                <HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD>
                <P>This action, pursuant to 5 U.S.C. 553, amends regulations issued to carry out a marketing order as defined in 7 CFR 900.2(j). This final rule is issued under Marketing Agreement No. 115 and Order No. 982, both as amended (7 CFR part 982), regulating the handling of hazelnuts grown in Oregon and Washington. Part 982 (referred to as the “Order”) is effective under the Agricultural Marketing Agreement Act of 1937, as amended (7 U.S.C. 601-674), hereinafter referred to as the “Act.” The Board locally administers the Order and is composed of growers and handlers of hazelnuts operating within the area of production, and a public member.</P>
                <P>The Agricultural Marketing Service (AMS) is issuing this final rule in conformance with Executive Orders 12866, 13563, and 14094. Executive Orders 12866 and 13563 direct agencies to assess all costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts and equity). Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, reducing costs, harmonizing rules, and promoting flexibility. Executive Order 14094 supplements and reaffirms Executive Orders 12866 and 13563 and directs agencies to conduct proactive outreach to engage interested and affected parties through a variety of means, such as through field offices, and alternative platforms and media. This action falls within a category of regulatory actions that the Office of Management and Budget (OMB) exempted from Executive Order 12866, 13563, and 14094 review.</P>
                <P>This final rule has been reviewed under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, which requires agencies to consider whether their rulemaking actions would have Tribal implications. AMS has determined that this rule is unlikely to have substantial direct effects on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or on the distribution of power and responsibilities between the Federal Government and Indian Tribes.</P>
                <P>This rule has been reviewed under Executive Order 12988, Civil Justice Reform. Under the Order now in effect, hazelnut handlers are subject to assessments. Funds to administer the Order are derived from such assessments. It is intended that the assessment rate will be applicable to all assessable hazelnuts for the 2023-2024 marketing year, and continue until amended, suspended, or terminated.</P>
                <P>The Act provides that administrative proceedings must be exhausted before parties may file suit in court. Under section 608c(15)(A) of the Act, any handler subject to an order may file with USDA a petition stating that the order, any provision of the order, or any obligation imposed in connection with the order is not in accordance with law and requesting a modification of the order or to be exempted therefrom. Such handler is afforded the opportunity for a hearing on the petition. After the hearing, USDA would rule on the petition. The Act provides that the district court of the United States in any district in which the handler is an inhabitant, or has his or her principal place of business, has jurisdiction to review USDA's ruling on the petition, provided an action is filed not later than 20 days after the date of the entry of the ruling.</P>
                <P>Section 982.61 provides authority for the Board, with the approval of AMS, to formulate an annual budget of expenses and collect assessments from handlers to administer the program. Members are familiar with the Board's needs and with the costs of goods and services in their local area and are, thus, in a position to formulate an appropriate budget and assessment rate. The assessment rate is formulated and discussed in a public meeting. Thus, all directly affected persons have an opportunity to participate and provide input.</P>
                <P>For the 2017-2018 marketing year and subsequent marketing years, the Board recommended, and AMS approved, an assessment rate of $12 per ton (equivalent to $0.006 per pound) of hazelnuts. That rate continues in effect from marketing year to marketing year until modified, suspended, or terminated by AMS upon recommendation and information submitted by the Board or other information available to AMS. This final rule will decrease the assessment rate from $0.006 per pound to $0.005 per pound for the 2023-2024 marketing year and subsequent marketing years.</P>
                <P>
                    The Board met on June 29, 2023, and recommended 2023-2024 marketing year expenditures of $1,815,000 and an assessment rate of $10 per ton (the equivalent of $0.005 per pound) of hazelnuts handled for the 2023-2024 
                    <PRTPAGE P="15956"/>
                    marketing year and subsequent marketing years. In comparison, last year's budgeted expenditures were $2,378,550. The assessment rate of $0.005 per pound is $0.001 lower than the rate currently in effect. The Board recommended decreasing the assessment rate to better align assessment revenue with budgeted expenses and to reduce the financial burden on the industry in a period of low commodity prices. The Board projects handler receipts of 85,000 tons (170 million pounds) of hazelnuts for the 2023-2024 marketing year, which is 10,000 tons (20 million pounds) more than was projected for the 2022-2023 marketing year.
                </P>
                <P>The expenditures totaling $1,815,000 recommended by the Board for the 2023-2024 marketing year include $670,000 for promotional activities, $300,000 for contingency/undesignated, $100,000 for marketing research, $100,000 for research endowment, $378,000 for administrative activities, and $267,000 for miscellaneous expenses. By comparison, budgeted expenditures for the 2022-2023 marketing year for promotional activities, contingency, marketing research, research endowment, administrative activities, and miscellaneous expenses were $1,251,200, $200,000, $150,000, $100,000, $347,350, and $330,000, respectively. The Board's 2023-2024 marketing year budget was reduced to account for generally lower commodity prices and decreased industry revenue.</P>
                <P>
                    The expected 170 million pounds of assessable hazelnuts from the 2023 crop will generate $850,000 in assessment revenue at the assessment rate established herein (170 million pounds multiplied by $0.005 assessment rate). The remaining $965,000 needed to cover budgeted expenditures will come from new grant funds and reserve funds carried over from previous marketing years. The Board anticipates $495,000 in Federal grants administered by USDA's Foreign Agricultural Service.
                    <SU>1</SU>
                    <FTREF/>
                     The remaining $470,000 necessary to cover budgeted expenditures will come from its monetary reserve. The decreased assessment rate should be appropriate to ensure that the Board has sufficient revenue, along with grants awarded and reserve funds, to fully fund its 2023-2024 marketing year budgeted expenditures and still maintain a level of reserve funds that the Board believes is appropriate.
                </P>
                <FTNT>
                    <P>
                        <SU>1</SU>
                         Specifically, $110,000 in Agricultural Trade Promotion program funds, $300,000 in Market Access Program funds, and $85,000 in Technical Assistance for Specialty Crop program funds.

                </FTNT>
                <P>The Board derived the recommended assessment rate by considering anticipated expenses, an estimated 2023 crop volume of 170 million pounds of assessable hazelnuts, grants that have been awarded, and the amount of funds available in the authorized reserve. Income derived from handler assessments ($850,000), and funds from other sources ($965,000), is expected to be adequate to cover budgeted expenses ($1,815,000).</P>
                <P>The assessment rate established herein will continue in effect indefinitely unless modified, suspended, or terminated by AMS upon recommendation and information submitted by the Board or other available information.</P>
                <P>Although this assessment rate will be in effect for an indefinite period, the Board will continue to meet prior to or during each marketing year to recommend a budget of expenses and consider recommendations for modification of the assessment rate. The dates and times of Board meetings are available from the Board or AMS. Board meetings are open to the public and interested persons may express their views at these meetings. AMS would evaluate Board recommendations and other available information to determine whether modification of the assessment rate is needed. Further rulemaking would be undertaken as necessary. The Board's 2023-2024 marketing year budget, and those for subsequent marketing years, will be reviewed and, as appropriate, approved by AMS.</P>
                <HD SOURCE="HD1">Final Regulatory Flexibility Analysis</HD>
                <P>Pursuant to requirements set forth in the Regulatory Flexibility Act (RFA) (5 U.S.C. 601-612), AMS has considered the economic impact of this final rule on small entities. Accordingly, AMS has prepared this final regulatory flexibility analysis.</P>
                <P>The purpose of the RFA is to fit regulatory actions to the scale of businesses subject to such actions in order that small businesses will not be unduly or disproportionately burdened. Marketing orders issued pursuant to the Act, and the rules issued thereunder, are unique in that they are brought about through group action of typically small entities acting on their own behalf.</P>
                <P>There are approximately 1,103 producers of hazelnuts in the production area and 14 handlers subject to regulation under the Order. At the time this analysis was prepared, small agricultural producers of hazelnuts were defined by the Small Business Administration (SBA) as those having annual receipts equal to or less than $3,750,000 (North American Industry Classification System code 111335), and small agricultural service firms were defined as those whose annual receipts are equal to or less than $34,000,000 (North American Industry Classification System code 115114) (13 CFR 121.201).</P>
                <P>According to the National Agricultural Statistics Service (NASS), the average producer price received for hazelnuts sold in Oregon specifically in 2022 was $1,300 per ton. Total production of hazelnuts for the 2022 season was reported by the NASS to be 68,000 tons. Using the average price and production data from the 2022 crop year, the most recent year for which there is NASS data available, the total 2022 crop value of hazelnuts could be estimated to be $88,400,000 (68,000 tons times $1,300 per ton). Dividing the crop value by the estimated number of producers (1,103) yields estimated average receipts per hazelnut producer of $80,145, which is well below the SBA threshold for small producers.</P>
                <P>In addition, according to AMS Market News data, the reported average 2021-2022 marketing year shipping point price for hazelnuts was $126.82 per 50-pound container, or $2.54 per pound ($126.82 per 50-pound container divided by 50 pounds). Multiplying the 2022 hazelnut production of 136,000,000 pounds (68,000 tons) by the estimated average price per pound of $2.54 equals $345,440,000 of estimated handler receipts. Dividing this figure by the 14 regulated handlers yields estimated average annual handler receipts of approximately $24,674,286 ($345,440,000 divided by 14 handlers), which is below the SBA threshold for small agricultural service firms. Therefore, using the above data, most of the producers and handlers of hazelnuts may be classified as small entities.</P>
                <P>This rule will decrease the assessment rate collected from handlers for the 2023-2024 marketing year and subsequent marketing years from $0.006 to $0.005 per pound of assessable hazelnuts. The Board unanimously recommended 2023-2024 marketing year expenditures of $1,815,000 and an assessment rate of $10 per ton ($0.005 per pound) of assessable hazelnuts. The assessment rate of $0.005 per pound is $.001 lower than the current rate. The Board expects the industry to handle 85,000 tons (170 million pounds) of assessable hazelnuts during the 2023-2024 marketing year.</P>
                <P>
                    Thus, at the $0.005 per pound rate, the Board anticipates $850,000 in assessment income (170 million pounds multiplied by $0.005 per pound). The Board also expects to use grant funds 
                    <PRTPAGE P="15957"/>
                    and the Board's monetary reserve to cover the remaining $965,000 of expenses. Income derived from handler assessments, along with grants and reserve funds, should be adequate to meet budgeted expenditures for the 2023-2024 marketing year.
                </P>
                <P>The major expenditures recommended by the Board for the 2023-2024 marketing year include $670,000 for promotional activities, $300,000 for contingency/undesignated, $100,000 for marketing research, $100,000 for research endowment, $378,000 for administrative activities, and $267,000 for miscellaneous expenses. Budgeted expenditures for the 2022-2023 marketing year were $1,251,200 for promotional activities, $200,000 for contingency/undesignated, $150,000 for marketing research, $100,000 for research endowment, $347,350 for administrative activities, and $330,000 for miscellaneous, respectively.</P>
                <P>The Board's 2023-2024 marketing year budget was reduced $563,550 from the prior year's budget to account for generally lower commodity prices and decreased industry revenue. In addition, the Board recommended decreasing the assessment rate to reduce the financial burden on the handlers and growers during the current environment of depressed prices. In recent years, the Board has utilized reserve funds to partially fund its budgeted expenditures. The Board's 2023-2024 marketing year budget again utilizes funds from the financial reserve to subsidize expenditures, but at a lower amount than in previous years. With this action, the Board's reserve balance will be maintained at a level that the Board believes is appropriate and is compliant with the provisions of the Order.</P>
                <P>Prior to arriving at the budget and assessment rate, the Board discussed various alternatives, including maintaining the current assessment rate of $0.006 per pound and reducing the assessment rate to $0.0055 per pound ($11 per ton). However, the Board determined that the recommended assessment rate will be able to reduce the financial burden on the industry and still fund most of the Board's budgeted expenses without drawing down reserves at an unsustainable rate. The assessment rate of $0.005 per pound of hazelnuts was derived by considering anticipated expenses, the projected volume of assessable hazelnuts, the projected monetary balance held in reserve, and additional pertinent factors.</P>
                <P>A review of NASS information indicates that the average producer price for the 2022 crop year was $0.65 per pound ($1,300 per ton). Further, NASS reported the quantity of hazelnuts harvested in the 2022 crop year was 136 million pounds (68,000 tons), which yields estimated total producer revenue for 2022 of $88,400,000 ($0.65 per pound multiplied by 136 million pounds). Therefore, utilizing the assessment rate of $0.005 per pound, the estimated assessment revenue as a percentage of total producer revenue will be approximately 0.77 percent ($0.005 per pound multiplied by 136 million pounds divided by $88,400,000 and multiplied by 100).</P>
                <P>This action will decrease the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers, and some of the costs may be passed on to growers. However, these costs are expected to be offset by the benefits derived by the operation of the Order.</P>
                <P>The Board's meetings are widely publicized throughout the production area. The hazelnut industry and all interested persons are invited to attend the meetings and participate in Board deliberations on all issues. Like all Board meetings, the June 29, 2023, meeting was a public meeting and all entities, both large and small, were able to express views on this issue.</P>
                <P>In accordance with the Paperwork Reduction Act of 1995, (44 U.S.C. Chapter 35), the Order's information collection requirements have been previously approved by OMB and assigned OMB No. 0581-0178, Vegetable and Specialty Crops. No changes in those requirements will be necessary as a result of this rule. Should any changes become necessary, they would be submitted to OMB for approval.</P>
                <P>This final rule will not impose any additional reporting or recordkeeping requirements on either small or large hazelnut handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies.</P>
                <P>AMS is committed to complying with the E-Government Act to promote the use of the internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes.</P>
                <P>AMS has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule.</P>
                <P>
                    A proposed rulemaking concerning this action was published in the 
                    <E T="04">Federal Register</E>

                    Sections 13801-13808 of the Tax Cuts and Jobs Act of 2017 (Pub. L. 115-97), signed December 22, 2017, commonly referred to as the Craft Beverage Modernization Act (CBMA), amended the Internal Revenue Code for two calendar years with respect to the tax treatment of imported alcohol, including beer, wine, and distilled spirits. The CBMA authorized reduced tax rates and tax credits for imported alcohol and permitted the refund of taxes paid prior to assigning a reduced tax rate or tax credit.

                     Public Law 116-94. On December 27, 2020, the Taxpayer Certainty and Disaster Tax Relief Act of 2020 (Tax Relief Act) was enacted.

                     Public Law 116-260, Division EE, sections 106-110. The Tax Relief Act amended and made permanent the CBMA, and directed the Secretary of the Treasury to implement and administer amended provisions concerning imported alcohol, in coordination with CBP. This authority was subsequently delegated to the Alcohol and Tobacco Tax and Trade Bureau (TTB). The relevant provisions of the Tax Relief Act became effective on January 1, 2023.

                     (87 FR 80442) to update the regulations issued in CBP Dec. 18-09, to reflect the transfer of authority for administration of the CBMA import refund program to TTB, and to direct the public to the relevant TTB regulations regarding refunds administered by TTB, in 27 CFR parts 27 and 70. Specifically, the interim final rule amended section 24.36 of title 19 of the Code of Federal Regulations (19 CFR 24.36). CBP Dec. 22-26 provided for the submission of comments from December 30, 2022, to March 2, 2023. No comments were received.

                <HD SOURCE="HD2">A. Executive Orders 13563, 12866, and 14094</HD>
                <P>Executive Orders 13563 and 12866 direct agencies to assess the costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, of reducing costs, of harmonizing rules, and of promoting flexibility. This final rule is not a “significant regulatory action,” under section 3(f) of Executive Order 12866, as amended by Executive Order 14094. Accordingly, the Office of Management and Budget (OMB) has not reviewed this regulation.</P>

                    The Regulatory Flexibility Act (5 U.S.C. 601 
                    <E T="03">et seq.</E>
                    ), as amended by the Small Business Regulatory Enforcement and Fairness Act of 1996, requires an agency to prepare and make available to the public a regulatory flexibility analysis that describes the effect of a proposed rule on small entities (
                    <E T="03">i.e.,</E>
                     small businesses, small organizations, and small governmental jurisdictions) when the agency is required to publish a general notice of proposed rulemaking for a rule. Since a general notice of proposed rulemaking is not necessary for this final rule, CBP is not required to prepare a regulatory flexibility analysis for this final rule.

                <P>
                    The Committee was established on December 12, 2023, and notice of establishment was published in the 
                    <E T="04">Federal Register</E>
                     on December 13, 2023 (88 FR 86344).
                </P>
                <P>The Committee reviews and evaluates data on the safety and effectiveness of marketed and investigational human drug and biologic products for use in the treatment of genetic metabolic diseases and makes appropriate recommendations to the Commissioner of Food and Drugs (the Commissioner).</P>
                <P>The Committee shall consist of a core of nine voting members, including the Chair. Members and the Chair are selected by the Commissioner or designee from among authorities knowledgeable in the fields of medical genetics, manifestations of inborn errors of metabolism, small population trial design, translational science, pediatrics, epidemiology, or statistics and related specialties. Members will be invited to serve for overlapping terms of up to 4 years. Non-Federal members of this Committee will serve either as special government employees or non-voting representatives. Federal members will serve as regular government employees or ex 1652fficious. The core of voting members may include one technically qualified member, selected by the Commissioner or designee, who is identified with consumer interests and is recommended by either a consortium of consumer-oriented organizations or other interested persons. In addition to the voting members, the Committee may include one non-voting representative member who is identified with industry interests. There may also be an alternate industry representative.</P>
                <P>The Committee name and function have been established with the establishment of the Committee charter. The change became effective December 12, 2023. Therefore, the Agency is amending § 14.100 (21 CFR 14.100) to add the Committee name and function to its current list as set forth in the regulatory text of this document.</P>
                <P>Under 5 U.S.C. 553(b)(4)(B) and (d) and 21 CFR 10.40(d) and ©, the Agency finds good cause to dispense with notice and public comment procedures and to proceed to an immediate effective date on this rule.</P>
                <P>Notice and public comment and a delayed effective date are unnecessary and are not in the public interest as this final rule is merely codifying the addition of the name and function of the GeMDAC to the list of standing FDA advisory committees. The establishment of the Committee is already effective, and the name and function that will be added to § 14.100 reflect the Committee charter. The Agency is amending § 14.100(c)(18) as set forth in the regulatory text of this document.</P>

                <P>We proposed to approve this rule because we determined that it complies with the relevant CAA requirements. Our proposed action contains more information on the rule and our evaluation.</P>
                <HD SOURCE="HD1">II. Public Comments and EPA Responses</HD>
                <P>The EPA's proposed action provided a 30-day public comment period. During this period, we received no comments.</P>

                    No comments were submitted. Therefore, as authorized in section 110(k)(3) of the Act, the EPA is approving SMAQMD Rule 307 into the California SIP. The March 23, 2023 version of Rule 307 will replace the 
                    <PRTPAGE P="15963"/>
                    previously approved version of this rule in the SIP. This final approval action also removes the EPA's obligation to promulgate a Federal Implementation Plan (FIP) for the SMAQMD portion of the Sacramento Metro ozone nonattainment area by permanently stopping the FIP clock associated with the January 17, 2023 (88 FR 2541) finding of failure to submit.

                <P>
                    In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference of SMAQMD Rule 307, “Clean Air Act Penalty Fees,” amended on March 23, 2023, which addresses the CAA section 185 fee program requirements. The EPA has made, and will continue to make, these documents available through 
                    <E T="03">www.regulations.gov</E>
                     and at the EPA Region IX Office (please contact the person identified in the

                <P>Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:</P>
                <P>• Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 14094 (88 FR 21879, April 11, 2023);</P>
                <P>
                    • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.S. 3501 
                    <E T="03">et seq.</E>
                    );
                </P>
                <P>
                    • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 
                    <E T="03">et seq.</E>
                    );
                </P>
                <P>• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);</P>
                <P>• Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);</P>
                <P>• Is not subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it approves a state program;</P>
                <P>• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); and</P>
                <P>• Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act.</P>
                <P>In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).</P>
                <P>Executive Order 12898 (Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations, 59 FR 7629, February 16, 1994) directs Federal agencies to identify and address “disproportionately high and adverse human health or environmental effects” of their actions on minority populations and low-income populations to the greatest extent practicable and permitted by law. The EPA defines environmental justice (EJ) as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” The EPA further defines the term fair treatment to mean that “no group of people should bear a disproportionate burden of environmental harms and risks, including those resulting from the negative environmental consequences of industrial, governmental, and commercial operations or programs and policies.”</P>
                <P>The State did not evaluate environmental justice considerations as part of its SIP submittal; the CAA and applicable implementing regulations neither prohibit nor require such an evaluation. The EPA did not perform an EJ analysis and did not consider EJ in this action. Consideration of EJ is not required as part of this action, and there is no information in the record inconsistent with the stated goal of Executive Order 12898 of achieving environmental justice for people of color, low-income populations, and Indigenous peoples.</P>
                <P>This action is subject to the Congressional Review Act, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. This action is not a “major rule” as defined by 5 U.S.C. 804(2).</P>
                <P>Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by May 6, 2024. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)</P>

                    <P>The FAA proposes to supersede Airworthiness Directive (AD) 2022-02-10, which applies to certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. AD 2022-02-10 requires replacement of certain titanium screws. Since the FAA issued AD 2022-02-10, affected parts have been found in other areas of certain Falcon 7X airplanes as well as in additional Falcon 7X airplanes. This proposed AD would continue to require the actions in AD 2022-02-10, add other locations for screw replacement, and revise the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.</P>

                <P>The FAA issued AD 2022-02-10, Amendment 39-21907 (87 FR 7025, February 8, 2022) (AD 2022-02-10), for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. AD 2022-02-10 was prompted by MCAI originated by EASA, which is the Technical Agent for the Member States of the European Union. EASA issued AD 2021-0047, dated February 16, 2021, to correct an unsafe condition.</P>
                <P>AD 2022-02-10 requires replacement of certain titanium screws. The FAA issued AD 2022-02-10 to address failure of an affected screw installed in a critical location, possibly resulting in reduced structural integrity of the airplane. See the MCAI for additional background information.</P>
                <HD SOURCE="HD1">Actions Since AD 2022-02-10 Was Issued</HD>
                <P>
                    Since the FAA issued AD 2022-02-10, EASA superseded EASA AD 2021-
                    <PRTPAGE P="15966"/>
                    0047, dated February 16, 2021, and issued EASA AD 2023-0207, dated November 21, 2023 (also referred to as the MCAI), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. The MCAI states that since EASA issued AD 2021-0047, it was determined that affected parts have been installed in production in additional areas of certain Model FALCON 7X airplanes already included in the applicability of EASA AD 2021-0047. Additionally, it was determined that additional Model FALCON 7X airplanes were not included in the applicability of EASA AD 2021-0047.

                <P>This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type design.</P>
                <HD SOURCE="HD1">Proposed AD Requirements in This NPRM</HD>
                <P>This proposed AD would retain certain requirements of AD 2022-02-10. This proposed AD would require accomplishing the actions specified in EASA AD 2023-0207 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD.</P>
                <HD SOURCE="HD1">Explanation of Required Compliance Information</HD>
                <P>
                    In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2023-0207 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2023-0207 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2023-0207 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2023-0207. Service information required by EASA AD 2023-0207 for compliance will be available at 
                    <E T="03">regulations.gov</E>
                     under Docket No. FAA-2024-0457 after the FAA final rule is published.

                <HD SOURCE="HD1">Authority for This Rulemaking</HD>
                <P>Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.</P>
                <P>The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.</P>
                <HD SOURCE="HD1">Regulatory Findings</HD>
                <P>The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132.

The proposed rule would amend the definition of hazardous waste applicable to corrective action to address releases from solid waste management units at RCRA-permitted treatment, storage, and disposal facilities and make related conforming amendments, thereby 
                        <PRTPAGE P="15968"/>
                        providing clear regulatory authority to fully implement the Resource Conservation and Recovery Act (RCRA) statutory requirement that permitted facilities conduct corrective action to address releases not only of substances listed or identified as hazardous waste in the regulations but of any substance that meets the statutory definition of hazardous waste. The proposed rule would also provide notice of EPA's interpretation that the statutory definition of hazardous waste applies to corrective action for releases from solid waste management units at permitted and interim status facilities.

                <P>
                    On February 8, 2024, the Agency published in the 
                    <E T="04">Federal Register</E>
                     (89 FR 8598) a proposed rule that would amend the regulations applicable to RCRA treatment, storage, and disposal facilities in two related respects. First, it would amend the definition of hazardous waste applicable to corrective action. Specifically, it would amend the definition in § 260.10 to expressly apply the RCRA section 1004(5) statutory definition of hazardous waste to corrective action requirements under § 264.101 and 40 CFR part 264 Subpart S. Similarly, it would amend the identical definition in the hazardous waste facility permitting regulations, § 270.2, to expressly apply the statutory definition of hazardous waste to the requirements relating to corrective action in § 270.14(d). These proposed revisions would more clearly provide EPA authority to address, through corrective action for solid waste management units, releases of the full universe of substances that the statute intended—not only hazardous waste and hazardous constituents listed or identified in the regulations, but all substances that meet the definition of hazardous waste in RCRA section 1004(5) at a facility. These proposed amendments are consistent with EPA's longstanding interpretation of the RCRA statute.
                </P>
                <P>Second, this proposed rule would add RCRA sections 3004(u) and (v) and 3008(h) to the statutory authorities identified in § 261.1(b)(2). That section provides that the statutory definitions of solid and hazardous waste govern the scope of EPA's authority under certain sections of RCRA, not the more limited 40 CFR part 261 regulatory definitions. These revisions provide notice of and codify the Agency's interpretation of the statute—that it provides authority to address releases from solid waste management units of all substances that meet the definition of hazardous waste under the statute.</P>
                <P>Following publication of the proposed rule, several members of the public requested that the Agency extend the comment period.</P>
                <P>In response to these requests, the Agency is extending the comment period for 15 days, until March 26, 2024. EPA does not want to unnecessarily delay this rulemaking and believes that this 15-day extension provides more than adequate time for reviewers to review the proposed rule and to submit comments given the very narrow scope of the rulemaking, and the limited amount of material reviewers need to review.</P>

                <P>
                    Pursuant to the PRA, the Agency is publishing this Notice to inform the public that the Agency will submit this proposed collection to the Office of Management and Budget (OMB) for approval. The Agency previously published this proposed information collection in the 
                    <E T="04">Federal Register</E>
                     on October 31, 2023 (88 FR 74401) with a 60-day comment period. The proposed information collection activity provides a means to garner qualitative customer and stakeholder feedback in an efficient, timely manner. By qualitative feedback we mean information that provides useful insights on perceptions and opinions but are not statistical surveys that yield quantitative results that can be generalized to the population of study. This feedback will provide insights into customer or stakeholder perceptions, experiences, and expectations, provide an early warning of issues with service, or focus attention on areas where communication, training, or changes in operations might improve delivery of products or services. These collections will allow for ongoing, collaborative, and actionable communications between the Agency and its customers and stakeholders. It will also allow feedback to contribute directly to the improvement of program management.
                </P>
                <P>The Agency will collect, analyze, and interpret information gathered through this generic clearance to identify strengths and weaknesses of the current services, information, and make improvements in service delivery based on feedback. The solicitation of feedback will target areas such as: timeliness, appropriateness, accuracy of information, courtesy, efficiency of service delivery, and resolution of issues with service delivery. Responses will be assessed to plan and inform efforts to improve or maintain the quality of service offered to the public. The Agency will only submit a collection for approval under this generic clearance if it meets the following conditions:</P>
                <P>• Information gathered will be used only internally for general service improvement and program management purposes and is not intended for release outside of the agency (if released, procedures outlined in Question 16 will be followed);</P>
                <P>• Information gathered will not be used for the purpose of substantially informing influential policy decisions;</P>
                <P>• Information gathered will yield qualitative information; the collections will not be designed or expected to yield statistically reliable results or used as though the results are generalizable to the population of study;</P>
                <P>• The collections are voluntary;</P>
                <P>• The collections are low-burden for respondents (based on considerations of total burden hours, total number of respondents, or burden-hours per respondent) and are low-cost for both the respondents and the Federal Government;</P>
                <P>• The collections are non-controversial and do not raise issues of concern to other Federal agencies;</P>
                <P>• Any collection is targeted to the solicitation of opinions from respondents who have experience with the program or may have experience with the program in the near future; and</P>
                <P>• With the exception of information needed to provide remunerations for participants of focus groups and cognitive laboratory studies, personally identifiable information (PII) is collected only to the extent necessary and is not retained.</P>
                <P>As a general matter, information collections will not result in any new system of records containing privacy information and will not ask questions of a sensitive nature, such as sexual behavior and attitudes, religious beliefs, and other matters that are commonly considered private.</P>
                <P>The projected average annual burden estimates for the next three years are listed below. The burdens have been increased from the 60-day notice amounts due to internal agency discussions on expected needs.</P>

                     Section 202 and 225 of the Agricultural Research, Extension, and Education Reform Act of 1998 (AREERA) which requires that a plan of work must be submitted by each institution and approved by the National Institute of Food and Agriculture (NIFA) before formula funds may be provided to the 1862 and 1890 land-grant institutions. The plan of work must address critical agricultural issues in the State and describe the programs and project targeted to address these issues using the NIFA formula funds. The plan of work also must describe the institution's multistate activities as well as their integrated research and extension activities. NIFA is requesting to continue to collect an update to the 5-Year Plan of Work which began with the Fiscal Year 2007, and as a result no longer needs to collect the initial 5-Year Plan. Also, as required by the Food Conservation and Energy Act of 2008 (FCEA) (

                    <E T="03">Need and Use of the Information:</E>
                     Institutions are required to annually report to NIFA the following: (1) The actions taken to seek stakeholder input to encourage their participation; (2) a brief statement of the process used by the recipient institution to identify individuals or groups who are stakeholders and to collect input from them; and (3) a statement of how collected input was considered. NIFA uses the information to provide feedback to the institutions on their Plans of Work and Annual Reports of Accomplishments and Results in order for institutions to improve the conduct and the delivery of their programs.
                </P>
                <P>Failure to comply with the requirements may result in the withholding of a recipient institution's formula funds and redistribution of its share of formula funds to other eligible institutions.</P>

                    Pursuant to 19 CFR 351.213(d)(3), Commerce will rescind an administrative review when there are no reviewable suspended entries. Based on our analysis of U.S. Customs and Border Protection (CBP) information, we preliminarily determine that 28 companies had no entries of subject merchandise during the POR. On January 16, 2024, we notified parties of our intent to rescind this administrative review with respect to the 28 companies listed in Appendix II that had no reviewable suspended entries during the POR.

The implementation of the standard also allows for uniform labeling and auditing of treated wood and, through a Memorandum of Understanding with the U.S. Department of Agriculture, labeling and auditing of wood packaging materials for international trade. As part of a five-year review process, NIST is seeking public comment and invites interested parties to review the revised standard and submit comments.</P>

                <P>
                    The MMPA prohibits the “take” of marine mammals, with certain exceptions. Sections 101(a)(5)(A) and (D) of the MMPA (16 U.S.C. 1361 
                    <E T="03">et seq.</E>
                    ) direct the Secretary of Commerce (as delegated to NMFS) to allow, upon request, the incidental, but not intentional, taking of small numbers of marine mammals by U.S. citizens who engage in a specified activity (other than commercial fishing) within a specified geographical region if certain findings are made and either regulations are promulgated or, if the taking is limited to harassment, an incidental harassment authorization is issued.
                </P>
                <P>
                    Authorization for incidental takings shall be granted if NMFS finds that the taking will have a negligible impact on the species or stock(s) and will not have an unmitigable adverse impact on the availability of the species or stock(s) for taking for subsistence uses (where relevant). Further, NMFS must prescribe the permissible methods of taking and other “means of effecting the least practicable adverse impact” on the affected species or stocks and their habitat, paying particular attention to rookeries, mating grounds, and areas of similar significance, and on the availability of such species or stocks for taking for certain subsistence uses 
                    <PRTPAGE P="15978"/>
                    (referred to here as “mitigation measures”). NMFS must also prescribe requirements pertaining to monitoring and reporting of such takings. The definition of key terms such as “take,” “harassment,” and “negligible impact” can be found in the MMPA and the NMFS's implementing regulations (see 16 U.S.C. 1362; 50 CFR 216.103).
                </P>
                <P>
                    NMFS' regulations implementing the MMPA at 50 CFR 216.107(e) indicate that IHAs may be renewed for additional periods of time not to exceed one year for each reauthorization. In the notice of proposed IHA for the initial IHA, NMFS described the circumstances under which we would consider issuing a renewal for this activity, and requested public comment on a potential renewal under those circumstances. Specifically, on a case-by-case basis, NMFS may issue a one-time 1-year renewal of an IHA following notice to the public providing an additional 15 days for public comments when (1) up to another year of identical, or nearly identical, activities as described in the Detailed Description of Specified Activities section of the initial IHA issuance notice is planned; or (2) the activities as described in the Description of the Specified Activities and Anticipated Impacts section of the initial IHA issuance notice would not be completed by the time the initial IHA expires and a renewal would allow for completion of the activities beyond that described in the 
                    <E T="02">DATES</E>
                     section of the notice of issuance of the initial IHA, provided all of the following conditions are met:
                </P>
                <P>1. A request for renewal is received no later than 60 days prior to the needed renewal IHA effective date (recognizing that the renewal IHA expiration date cannot extend beyond 1 year from expiration of the initial IHA);</P>
                <P>2. The request for renewal must include the following:</P>
                <P>
                    • An explanation that the activities to be conducted under the requested renewal IHA are identical to the activities analyzed under the initial IHA, are a subset of the activities, or include changes so minor (
                    <E T="03">e.g.,</E>
                     reduction in pile size) that the changes do not affect the previous analyses, mitigation and monitoring requirements, or take estimates (with the exception of reducing the type or amount of take); and
                </P>
                <P>• A preliminary monitoring report showing the results of the required monitoring to date and an explanation showing that the monitoring results do not indicate impacts of a scale or nature not previously analyzed or authorized; and</P>
                <P>3. Upon review of the request for renewal, the status of the affected species or stocks, and any other pertinent information, NMFS determines that there are no more than minor changes in the activities, the mitigation and monitoring measures will remain the same and appropriate, and the findings in the initial IHA remain valid.</P>
                <P>
                    An additional public comment period of 15 days (for a total of 45 days), with direct notice by email, phone, or postal service to commenters on the initial IHA, is provided to allow for any additional comments on the proposed renewal. A description of the renewal process may be found on our website at: 
                    <E T="03">https://www.fisheries.noaa.gov/national/marine-mammal-protection/incidental-harassment-authorization-renewals.</E>
                     Any comments received on the potential renewal, along with relevant comments on the initial IHA, have been considered in the development of this proposed IHA renewal, and a summary of agency responses to applicable comments is included in this notice. NMFS will consider any additional public comments prior to making any final decision on the issuance of the requested renewal, and agency responses will be summarized in the final notice of our decision.

                    To comply with the National Environmental Policy Act of 1969 (NEPA; 42 U.S.C. 4321 
                    <E T="03">et seq.</E>
                    ) and NOAA Administrative Order (NAO) 216-6A, NMFS must review our proposed action (
                    <E T="03">i.e.,</E>
                     the issuance of an IHA renewal) with respect to potential impacts on the human environment.
                </P>
                <P>This action is consistent with categories of activities identified in Categorical Exclusion B4 (incidental take authorizations with no anticipated serious injury or mortality) of the Companion Manual for NOAA Administrative Order 216-6A, which do not individually or cumulatively have the potential for significant impacts on the quality of the human environment and for which we have not identified any extraordinary circumstances that would preclude this categorical exclusion. Accordingly, NMFS determined that the issuance of the initial IHA qualified to be categorically excluded from further NEPA review. NMFS has preliminarily determined that the application of this categorical exclusion remains appropriate for this renewal IHA.</P>
                <HD SOURCE="HD1">History of Request</HD>
                <P>On March 29, 2023, NMFS issued an IHA to TMC to take marine mammals incidental to the construction of the cruise ship dock in Whittier, Alaska (88 FR 19927, April 4, 2023), effective from April 1, 2023 through March 31, 2024. On November 16, 2023, NMFS received an application for the renewal of that initial IHA. As described in the application for renewal IHA, the activities for which incidental take is requested consist of activities that are covered by the initial authorization but will not be completed prior to its expiration. As required, the applicant also provided a preliminary monitoring report which confirms that the applicant has implemented the required mitigation and monitoring, and which also shows that no impacts of a scale or nature not previously analyzed or authorized have occurred as a result of the activities conducted.</P>
                <HD SOURCE="HD1">Description of the Specified Activities and Anticipated Impacts</HD>
                <P>TMC's planned cruise ship construction project was planned to cover a 12-month window during which approximately 129 days of pile-installation and -removal activity will occur. This project involved installation and removal of seventy-two 36-inch (in) (0.91-meter (m)) temporary steel pile guides and installation of thirty-six 36-in (0.91-m), sixteen 42-in (1.1-m), and twenty 48-in (1.2-m) permanent steel piles. Three different installation methods were planned to be used including vibratory installation of piles into dense material, impact pile driving to drive piling to tip elevation, and the Down-the-Hole (DTH) hammer to drill pile into the bedrock. TMC planned to deploy a bubble curtain to the 60-foot (ft) (18.3-m) isobath. This was planned to be used during all activities that fall below the 60-ft (18.3-m) isobath.</P>
                <P>Due to unexpected winter weather conditions causing slower construction, TMC will not complete the initial construction during the 1-year period. Specifically, at the time of the renewal request, TMC had completed installation of 51 permanent piles to construct the approach trestle, 2 float restraint dolphins, and most of the mooring trestle. With the remaining time under the initial IHA, TMC anticipates completing at a minimum installation of 10 additional permanent piles.</P>
                <P>
                    This renewal request is to cover the subset of the activities covered in the initial IHA that will not be completed during the effective IHA period. TMC plans to complete the remaining 
                    <PRTPAGE P="15979"/>
                    construction activities, which would include at maximum installation of four 48-in piles for one mooring dolphin, installation of seven 36-in piles for the remainder of the mooring trestle, and installation and removal of eleven 36-in temporary piles to guide installation of the remaining permanent piles.
                </P>
                <P>The likely or possible impacts of the TMC's proposed activity on marine mammals could involve both non-acoustic and acoustic stressors and is unchanged from the impacts described in the initial IHA. Potential non-acoustic stressors could result from the physical presence of the equipment, vessels, and personnel; however, any impacts to marine mammals are expected to primarily be acoustic in nature. Sounds resulting from pile installation, removal, and drilling may result in the incidental take of marine mammals by Level A and Level B harassment in the form of auditory injury or behavioral harassment.</P>
                <HD SOURCE="HD2">Detailed Description of the Activity</HD>
                <P>A detailed description of the construction activities for which take is proposed here may be found in the notices of the proposed and final IHAs for the initial authorization (88 FR 9227, February 13, 2023; 88 FR 19927, April 4, 2023). As previously mentioned, this request is for a subset of the activities considered for the initial IHA that would not be completed prior to its expiration. The location, timing, and nature of the activities, including the types of equipment planned for use, are identical to those described in the previous notice for the initial IHA. The proposed renewal IHA would be effective from April 1, 2024 through March 31, 2025.</P>
                <HD SOURCE="HD2">Description of Marine Mammals</HD>
                <P>A description of the marine mammals in the area of the activities for which authorization of take is proposed here, including information on abundance, status, distribution, and hearing, may be found in the notice of the proposed IHA for the initial authorization (88 FR 9227, February 13, 2023).</P>
                <P>Since the initial IHA was published, NMFS published the final 2022 Alaska and Pacific Stock Assessment Reports (SARs), which describe revised stock structures under the MMPA for humpback whales. In the initial notice of proposed and final IHAs, we explained these proposed changes and that these changes would be adopted when final. Upon finalization of these revised stock structures, we have made appropriate updates, including attribution of take numbers to stock (see Estimated Take).</P>
                <P>
                    The revision to humpback whale stock structure modifies the previously MMPA-designated humpback stocks to align more closely with the ESA-designated distinct population segments (DPSs) (Caretta 
                    <E T="03">et al.,</E>
                     2023; Young 
                    <E T="03">et al.,</E>
                     2023). Specifically, the three existing North Pacific humpback whale stocks (Central North Pacific and Western North Pacific stocks addressed in the Alaska SAR and the California/Oregon/Washington stock addressed in the Pacific SAR) were replaced by five stocks (Western North Pacific, Hawaii, and Mexico-North Pacific stocks addressed in the Alaska SAR and the Central America/Southern Mexico-CA/OR/WA and Mainland Mexico-CA/OR/WA stocks addressed in the Pacific SAR) (Caretta 
                    <E T="03">et al.,</E>
                     2023; Young 
                    <E T="03">et al.,</E>
                     2023).
                </P>
                <P>In the initial notice of the proposed and final IHA, NMFS assumed that humpbacks in the action area were from the Central North Pacific Stock, Western North Pacific Stock, and CA/OR/WA Stock, and therefor authorized take of humpbacks from these stocks. Based on the revised stock designations, no take of WNP stock whales would occur, and in the proposed renewal IHA humpback whales are now assumed to be members of either the Hawaii stock or the Mexico-North Pacific stock, which corresponds with the takes previously authorized for the Central North Pacific Stock and CA/OR/WA Stocks, respectively. However, based on the work remaining in the renewal IHA, the takes proposed for authorization through this renewal would only be from the Hawaii stock. In southeast Alaska, it is likely that only 2% of humpbacks would be from the Mexico-North Pacific stock, and based on the proportionally reduced take in this renewal, there are no calculated takes of the Mexico-North Pacific stock. Therefor in this renewal IHA, we propose to authorize take only of the Hawaii stock of humpback whale.</P>
                <P>NMFS has reviewed the preliminary monitoring data from the initial IHA, recent draft and final Stock Assessment Reports including the updated humpback whale stock structure, and determined that neither this nor any other new information affects which species have the potential to be affected or the pertinent information in the Description of the Marine Mammals in the Area of Specified Activities contained in the supporting documents for the initial IHA (88 FR 9227, February 13, 2023).</P>

                <P>A description of the potential effects of the specified activity on marine mammals and their habitat for the activities for which the authorization of take is proposed here may be found in the notice of the proposed IHA for the initial authorization (88 FR 9227, February 13, 2023). NMFS has reviewed the monitoring data from the initial IHA, recent draft Stock Assessment Reports, information on relevant Unusual Mortality Events, and other scientific literature, and determined that neither this nor any other new information affects our initial analysis of impacts on marine mammals and their habitat.</P>
                <HD SOURCE="HD2">Estimated Take</HD>
                <P>A detailed description of the methods and inputs used to estimate take for the specified activity are found in the notices of the proposed and final IHAs for the initial authorization (88 FR 9227, February 13, 2023; 88 FR 19927, April 4, 2023). Specifically, days of operation, area or space within which harassment is likely to occur, and marine mammal occurrence data applicable to this authorization remain unchanged from the initial IHA. Similarly, methods of take, daily take estimates and types of take remain unchanged from the initial IHA. The number of takes proposed for authorization in this renewal are a subset of the initial authorized takes that better represent the amount of activity left to complete. These takes, which reflect the lower number of remaining days of work, are indicated below in table 1. Takes are calculated using the same methodology as the initial IHA, and are just a proportion of the initial takes based on the days of work remaining.</P>

                <HD SOURCE="HD2">Description of Proposed Mitigation, Monitoring and Reporting Measures</HD>
                <P>The proposed mitigation, monitoring, and reporting measures included as requirements in this authorization are almost identical to those included in the FR notice announcing the issuance of the initial IHA, and the discussion of the least practicable adverse impact included in that document remains accurate (88 FR 19927, April 4, 2023).</P>
                <P>The following mitigation, monitoring, and reporting measures are proposed for this renewal:</P>
                <P>• The TMC must avoid direct physical interaction with marine mammals during construction activity. If a marine mammal comes within 10-m of such activity, operations must cease and vessels must reduce speed to the minimum level required to maintain steerage and safe working conditions, as necessary to avoid direct physical interaction;</P>
                <P>• Conduct training between construction supervisors and crews and the marine mammal monitoring team and relevant TMC staff prior to the start of all pile driving activity and when new personnel join the work, so that responsibilities, communication procedures, monitoring protocols, and operational procedures are clearly understood;</P>
                <P>• Pile driving activity must be halted upon observation of either a species for which incidental take is not authorized or a species for which incidental take has been authorized but the authorized number of takes has been met, entering or within the harassment zone;</P>
                <P>• TMC will establish and implement the shutdown zones. The purpose of a shutdown zone is generally to define an area within which shutdown of the activity would occur upon sighting of a marine mammal (or in anticipation of an animal entering the defined area). Shutdown zones typically vary based on the activity type and marine mammal hearing group;</P>
                <P>
                    • Monitoring must take place from 30 minutes prior to initiation of construction activity (
                    <E T="03">i.e.,</E>
                     pre-start clearance monitoring) through 30 minutes post-completion of construction activity;
                </P>
                <P>• Pre-start clearance monitoring must be conducted during periods of visibility sufficient for the lead Protected Species Observer (PSO) to determine the shutdown zones clear of marine mammals. Construction may commence when the determination is made;</P>
                <P>• If construction is delayed or halted due to the presence of a marine mammal, the activity may not commence or resume until either the animal has voluntarily exited and been visually confirmed beyond the shutdown zone or 15 minutes have passed without re-detection of the animal;</P>
                <P>• TMC must use soft start techniques when impact pile driving. Soft start requires contractors and equipment to slowly approach the work site creating a visual disturbance allowing animals in close proximity to construction activities a chance to leave the area prior to stone resetting or new stone placement. A soft start must be implemented at the start of each day's construction activity and at any time following cessation of activity for a period of 30 minutes or longer;</P>
                <P>• The TMC must employ up to four PSOs to monitor the shutdown and Level B harassment zones during pile driving and DTH activities;</P>
                <P>• Monitoring will be conducted 30 minutes before, during, and 30 minutes after construction activities. In addition, observers shall record all incidents of marine mammal occurrence, regardless of distance from activity, and shall document any behavioral reactions in concert with distance from construction activity;</P>
                <P>• The TMC must submit a draft report detailing all monitoring within 90 calendar days of the completion of marine mammal monitoring or 60 days prior to the issuance of any subsequent IHA for this project, whichever comes first;</P>
                <P>• TMC must conduct hydroacoustic monitoring as specified in the initial IHA and submit a hydroacoustic monitoring report;</P>
                <P>• The TMC must prepare and submit final report within 30 days following resolution of comments on the draft report from NMFS;</P>
                <P>• The TMC must submit all PSO datasheets and/or raw sighting data (in a separate file from the Final Report referenced immediately above); and</P>
                <P>• The TMC must report injured or dead marine mammals.</P>
                <HD SOURCE="HD1">Comments and Responses</HD>
                <P>As noted previously, NMFS published a notice of a proposed IHA (88 FR 9227, February 13, 2023) and solicited public comments on both our proposal to issue the initial IHA for Whittier Head of the Bay cruise ship dock project and on the potential for a renewal IHA, should certain requirements be met. During the 30-day public comment period, NMFS received no comments on either the proposal to issue the initial IHA for TMC's construction activities or on the potential for a renewal IHA.</P>
                <HD SOURCE="HD1">Preliminary Determinations</HD>
                <P>
                    The proposed renewal request consists of a subset of activities analyzed through the initial authorization described above. In analyzing the effects of the activities for the initial IHA, NMFS determined that TMC's activities would have a negligible impact on the affected species or stocks and that authorized take numbers of each species or stock were small relative to the relevant stocks (
                    <E T="03">e.g.,</E>
                     less than one-third the abundance of all stocks). The mitigation measures and monitoring and reporting requirements as described above are identical to the initial IHA.
                </P>
                <P>
                    NMFS has preliminarily concluded that there is no new information suggesting that our analysis or findings should change from those reached for the initial IHA. Based on the 
                    <PRTPAGE P="15981"/>
                    information and analysis contained here and in the referenced documents, NMFS has preliminarily determined the following: (1) the required mitigation measures will effect the least practicable impact on marine mammal species or stocks and their habitat; (2) the authorized takes will have a negligible impact on the affected marine mammal species or stocks; (3) the authorized takes represent small numbers of marine mammals relative to the affected stock abundances; (4) TMC's activities will not have an unmitigable adverse impact on taking for subsistence purposes as no relevant subsistence uses of marine mammals are implicated by this action; and (5) appropriate monitoring and reporting requirements are included.
                </P>
                <HD SOURCE="HD1">Endangered Species Act</HD>
                <P>
                    The NMFS Alaska Regional Office issued a Biological Opinion under section 7 of the Endangered Species Act (ESA; 16 U.S.C. 1531 
                    <E T="03">et seq.</E>
                    ) on the issuance of an IHA and potential renewal IHA to TMC under section 101(a)(5)(D) of the MMPA by the NMFS Office of Protected Resources. The Biological Opinion concluded that the action is not likely to jeopardize the continued existence of ESA-listed humpback whales or Steller sea lions.

                <P>
                    As a result of these preliminary determinations, NMFS proposes to issue a renewal IHA to TMC for conducting the cruise ship dock construction in Whittier, Alaska, from April 1, 2024 through March 31, 2025, provided the previously described mitigation, monitoring, and reporting requirements are incorporated.

                     The Dodd-Frank Wall Street Reform and Consumer Protection Act charges the CFPB with researching, analyzing, and reporting on topics relating to the CFPB's mission including consumer behavior, consumer awareness, and developments in markets for consumer financial products and services. To improve its understanding of consumers and institutional actors in financial markets, the CFPB makes use of data collected through the complaint process. The CFPB seeks to enhance the utility of these data by better understanding the broader population of consumers who experience issues with their financial products and services.
                </P>
                <P>The CFPB proposes to collect data with two new surveys intended to identify factors that influence a consumer's decision to use the complaint process. The initial pilot survey will focus on consumers who have experienced issues with their credit cards and will include a sample of people who have used the CFPB's complaint process, and another sample of people who experienced similar issues but did not file a complaint with the CFPB. This design (known as a case-control study) will allow us to identify key factors that are associated with submitting regulatory complaints.</P>
                <P>The pilot survey will inform a second survey which will focus on a broader range of products and services. The second survey will (to the extent feasible) cover additional products about which consumers can submit complaints to the CFPB including (but not limited to) mortgages, vehicle loans, bank accounts, and debts owed to third-party debt collectors. Both surveys will collect data about factors that may play a role in consumer's decision to submit a complaint. These include information about their use of a given product, the problems they encountered when using a given product, their attitudes and perceptions towards the product and its offeror, as well as demographic information.</P>
                <P>
                    <E T="03">Request for Comments:</E>
                     Comments are invited on: (a) Whether the collection of information is necessary for the proper performance of the functions of the CFPB, including whether the information will have practical utility; (b) The accuracy of the CFPB's estimate of the burden of the collection of information, including the validity of the methods and the assumptions used; (c) Ways to enhance the quality, utility, and clarity of the information to be collected; and (d) Ways to minimize the burden of the collection of information on respondents, including through the use of automated collection techniques or other forms of information technology. Comments submitted in response to this notice will be summarized and/or included in the request for OMB's approval. All comments will become a matter of public record.

                <P>In support of its model energy code determinations, DOE conducts a technical analysis to assess the energy savings impacts associated with the updated code (Standard 90.1-2022). DOE's review under ECPA is technical in nature and helps to inform and advise interested industry stakeholders of the effects of the updated code, as well as states and local governments who ultimately adopt, implement and enforce building codes. Although, DOE is an active participant in the review and update process for Standard 90.1-2022, as directed under ECPA (42 U.S.C. 6836(b)), the Department neither administers nor publishes the model energy codes. Additionally, the directive for states to update their energy efficiency codes based on the updated edition of Standard 90.1-2022 is ultimately rooted in ECPA. DOE's technical analysis serves as basis for DOE's determination and helps inform adopting states who seek to update their codes and comply with ECPA.</P>

                         Standard 90.1.-2022 added prescriptive requirements for onsite energy generation in certain building types and climate zones which is to be achieved through the use of renewable energy systems. This determination excludes these provisions relating to renewable energy systems because they fall outside the scope of DOE's section 6833(2)(B) review. However, related impacts on whole-building energy savings are reported in DOE's technical analysis developed in support of this determination.

                <P>DOE recognizes that some States do not have a State commercial building energy code or have a State code that does not apply to all commercial buildings. States may base their certifications on reasonable actions by units of general-purpose local government. Each such State must review the information obtained from the local governments and gather any additional data and testimony in preparing its own certification.</P>
                <P>The applicability of any State revisions to new or existing buildings would be governed by the State building codes. States should be aware that the scope of Standard 90.1-2022 includes high-rise (greater than three stories) multi-family residential buildings, and hotels, motels, and other transient residential building types of any height, as commercial buildings for energy code purposes. Consequently, commercial buildings, for the purposes of certification to DOE, would include high-rise multi-family residential buildings, hotels, motels, and other transient residential building types of any height.</P>

The certification must include a demonstration that the provisions of the State's commercial building energy code regarding energy efficiency meets or exceeds Standard 90.1-2022. If a State intends to certify that its commercial building energy code already meets or exceeds the requirements of Standard 90.1-2022, the State should provide an explanation of the basis for this certification (

                     director of the State energy office, State code commission, utility commission, or equivalent State agency having primary responsibility for commercial building energy codes), would provide the certification to the Secretary. Such a designated State official would also provide the certifications regarding the codes of units of general purpose local government based on information provided by responsible local officials.

                     Once a State has adopted an updated energy code, DOE strives to provide technical assistance supporting the successful implementation of such codes, including compliance tools, education and training, and support for the updated code. DOE has issued previous guidance on how it intends to respond to technical assistance requests related to implementation resources, such as building energy code compliance software. 79 FR 15112. The DOE Secretary is directed to provide incentive funding to States to implement the requirements of section 304, and to improve and implement State residential and commercial building energy efficiency codes, including increasing and verifying compliance with such codes.

                     This ICR covers information collection requirements in the final Federal Implementation Plan (FIP) for Oil and Natural Gas Well Production Facilities; Fort Berthold Indian Reservation (Mandan, Hidatsa, and Arikara Nation), North Dakota (40 CFR part 49, subpart K, §§ 49.4161 through 49.4168), herein referred to as the FBIR FIP. In general, owners or operators are required to: (1) conduct certain monitoring; (2) keep specific records to be made available at the EPA's request; and (3) to prepare and submit an annual report (40 CFR part 49, subpart K, §§ 49.4166 through 49.4168). These records and reports are necessary for the EPA Administrator (or the Tribal agency if delegated), for example, to: (1) confirm compliance status of stationary sources; (2) identify any stationary sources not subject to the requirements and identify stationary sources subject to the regulations; and (3) ensure that the stationary source control requirements are being achieved. All information submitted to us pursuant to the recordkeeping and reporting requirements for which a claim of confidentiality is made is safeguarded according to the agency policies set forth in 40 CFR part 2, subpart B.

                     The purpose of this information collection request is to assist the EPA in selecting federal advisory committee members who will be appointed as Special Government Employees (SGEs), mostly to the EPA's scientific and technical committees. To select SGE members as efficiently and cost effectively as possible, the Agency needs to evaluate potential conflicts of interest before a candidate is hired as an SGE and appointed as a member to a committee.
                </P>
                <P>Agency officials developed the “Confidential Financial Disclosure Form for Special Government Employees at the U.S. Environmental Protection Agency,” also referred to as Form 3110-48, for greater inclusion of information to discover any potential conflicts of interest as recommended by the Government Accountability Office.</P>

                     The CASAC was established pursuant to the Clean Air Act (CAA) Amendments of 1977, codified at 42 U.S.C. 7409(d)(2), to review air quality criteria and NAAQS and recommend to the EPA Administrator any new NAAQS and revisions of existing criteria and NAAQS as may be appropriate. As amended, 5 U.S.C., app. Section 109(d)(1) of the Clean Air Act (CAA) requires that EPA carry out a periodic review and revision, as appropriate, of the air quality criteria and the NAAQS for the six “criteria” air pollutants, including NO

                    <E T="52">X</E>
                     panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies. Pursuant to FACA and EPA policy, notice is hereby given that the CASAC NO

                     Panel will hold a public meeting to provide consultative advice on the IRP Vol. 2, and the Chartered CASAC will provide advice on the NAAQS review process.

                    <E T="03">Availability of meeting materials:</E>
                     All meeting materials, including the agendas, will be available on the CASAC web page at

                    <E T="03">Procedures for providing public input:</E>
                     Public comment for consideration by EPA's federal advisory committees and panels has a different purpose from public comment provided to EPA program offices. Therefore, the process for submitting comments to a federal advisory committee is different from the process used to submit comments to an EPA program office. Federal advisory committees and panels, including scientific advisory committees, provide independent advice to the EPA. Members of the public can submit relevant comments pertaining to the committee's charge or meeting materials. Input from the public to the CASAC will have the most impact if it provides specific scientific or technical information or analysis for the CASAC to consider or if it relates to the clarity or accuracy of the technical information. Members of the public wishing to provide comments should follow the instruction below to submit comments.

                <P>
                    <E T="03">Oral statements:</E>
                     In general, individuals or groups requesting an oral presentation at the meeting will be limited to five minutes. Each person making an oral statement should consider providing written comments as well as their oral statement so that the points presented orally can be expanded upon in writing. Persons interested in providing oral statements should contact the DFO, in writing (preferably via email) at the contact information noted under 
                    <E T="02">FOR FURTHER INFORMATION CONTACT</E>

                <P>
                    <E T="03">Written statements:</E>
                     Written statements will be accepted throughout the advisory process; however, for timely consideration by CASAC members, statements should be submitted to the DFO by April 9, 2024, for consideration at the April 16, 2024 meeting, and by April 18, 2024, for consideration at the April 25, 2024 meeting. Written statements should be supplied to the DFO at the contact information above via email. Submitters are requested to provide an unsigned version of each document because the SAB Staff Office does not publish documents with signatures on its websites. Members of the public should

                    be aware that their personal contact information if included in any written comments, may be posted to the CASAC website. Copyrighted material will not be posted without the explicit permission of the copyright holder.

                <P>
                    On February 6, 2006, the Agency published a final rule for the protection of human subjects in research (71 FR 6138) that called for creating a new, independent human studies review board (
                    <E T="03">i.e.,</E>
                     HSRB). The HSRB is a Federal advisory committee operating in accordance with the Federal Advisory Committee Act (FACA) 5 U.S.C. 10 (Pub. L. 92-463). The HSRB provides advice, information, and recommendations to EPA on issues related to scientific and ethical aspects of human subjects research. The major objectives of the HSRB are to provide advice and recommendations on: (1) research proposals and protocols that include human subjects; and (2) reports of completed research with human subjects. Typically, the HSRB reviews protocols and completed studies involving pesticide studies, such as worker exposure studies with agricultural handlers applying pesticides in field conditions; janitorial maintenance personnel applying antimicrobial pesticides in commercial settings; and field efficacy studies for skin applied insect repellent products. The HSRB reports to the EPA Administrator through EPA's Human Subjects Research Review Official (HSRRO). General information concerning the HSRB, including its charter, current membership, and activities can be found on the EPA website at 
                    <E T="03">https://www.epa.gov/osa/human-studies-review-board.</E>
                </P>
                <HD SOURCE="HD1">HSRB Membership</HD>
                <P>HSRB members serve as special government employees or regular government employees. Members are appointed by the EPA Administrator for either two or three year terms with the possibility of reappointment for additional terms, for a maximum of six years of service. The HSRB convenes on average four times a year, with all of the meetings being virtual. The average workload for HSRB members is approximately 20 hours per meeting, including the time spent at the meeting. Responsibilities of HSRB members include reviewing extensive background materials prior to meetings of the Board, preparing draft responses to Agency charge questions, attending Board meetings, participating in the discussion and deliberations at these meetings, drafting assigned sections of meeting reports, and assisting with the finalization of HSRB reports. EPA compensates special government employees for their time and provides reimbursement for travel and other incidental expenses associated with official government business related to the HSRB meetings.</P>
                <P>Members of the HSRB are subject to the provisions of 5 CFR part 2634, Executive Branch Financial Disclosure, as supplemented by the EPA in 5 CFR part 6401. In anticipation of this requirement, each nominee will be asked to submit confidential financial information that fully discloses, among other financial interests, the candidate's employment, stocks and bonds, and where applicable, sources of research support. The information provided is strictly confidential and will not be disclosed to the public. Before a candidate is considered further for service on the HSRB, EPA will evaluate each candidate to assess whether there is any conflict of financial interest, appearance of a lack of impartiality, or prior involvement with matters likely to be reviewed by the Board.</P>

                <P>
                    To nominate a candidate for consideration or self-nominate, please visit the HSRB website at

Interested candidates may self-nominate. EPA values and welcomes diversity. In an effort to obtain nominations of diverse candidates, EPA encourages nominations of women and men of all racial and ethnic groups, as well as from a variety of backgrounds (

                <P>
                    Nominations will be evaluated on the basis of several criteria, including: professional background, expertise, and experience that would contribute to the diversity of perspectives of the committee; interpersonal, oral, and written communication skills and other attributes that would contribute to the HSRB's collaborative process; consensus building skills; absence of any financial conflicts of interest or the appearance of a lack of impartiality, or lack of independence, or bias; and the

                    availability to participate in meetings and administrative sessions, participate in teleconferences, develop policy recommendations to the Administrator, and prepare recommendations and advice in reports.
                </P>
                <P>Candidates not selected for HSRB membership at this time may be considered for HSRB membership as vacancies arise in the future or for service as consultants to the HSRB.</P>

                <P>
                    Final selection of HSRB members is a discretionary function of the Agency and will be announced as soon as selections are made on the HSRB website at

                <HD SOURCE="HD1">Background on Common Formats Development</HD>
                <P>
                    The Patient Safety and Quality Improvement Act of 2005, 42 U.S.C. 299b-21 to 299b-26, (Patient Safety Act) and the related Patient Safety and Quality Improvement Final Rule, 42 CFR part 3 (Patient Safety Rule), published in the 
                    <E T="04">Federal Register</E>
                     on November 21, 2008, 73 FR 70731-70814, provide for the formation of Patient Safety Organizations (PSOs), which collect and analyze confidential and privileged information regarding the quality and safety of health care delivery that meets the definition of PSWP. Aggregation of these data enables PSOs and others to identify and address underlying causal factors of patient safety and quality issues.
                </P>
                <P>The Patient Safety Act provides for the development of standardized reporting formats using common language and definitions (Common Formats) to ensure that health care quality and patient safety data collected by PSOs and other entities are comparable. The Common Formats facilitate aggregation of comparable data at local, PSO, regional and national levels. In addition, the formats are intended to enhance the reporting of information that is standardized both clinically and electronically.</P>
                <P>AHRQ has developed Common Formats for Event Reporting for three settings of care—acute care hospitals, nursing homes, and community pharmacies—as well as for diagnostic safety events across all care settings. AHRQ-listed PSOs are required to collect patient safety work product in a standardized manner to the extent practical and appropriate; this is a requirement the PSO can meet by collecting such information using Common Formats. Additionally, providers and other organizations not working with an AHRQ-listed PSO can use the Common Formats in their work to improve quality and safety; however, they cannot benefit from the Federal confidentiality and privilege protections of the Patient Safety Act.</P>
                <P>Since February 2005, AHRQ has convened the Federal Patient Safety Work Group (PSWG) to assist AHRQ in developing and maintaining the Common Formats. The PSWG includes major health agencies within HHS as well as the Departments of Defense and Veterans Affairs. The PSWG helps assure the consistency of definitions/formats with those of relevant government agencies. In addition, AHRQ solicit comments from the private and public sectors regarding proposed versions of the Common Formats through the Patient Safety Organization Privacy Protection Center (PSOPPC). After receiving comments, the PSOPPC will solicit review of the formats by its Common Formats Expert Panel. Subsequently, PSOPPC will review this input and provide its feedback to AHRQ who then uses it to refine the Common Formats.</P>
                <P>For the Common Formats, it should be noted that AHRQ uses the term “surveillance” in this context to refer to the improved detection of events and calculation of adverse event rates in populations reviewed that will allow for collection of comparable performance data over time and across populations of patients. These formats are designed to provide, through retrospective review of medical records, information that is complementary to that derived from event reporting systems.</P>
                <P>
                    AHRQ is specifically interested in receiving feedback in order to guide the improvement of the formats. The draft Event Descriptions for the

                    <E T="03">Background on the CPSTF:</E>
                     The CPSTF is an independent, nonfederal panel whose members are appointed by the CDC Director. CPSTF members represent a broad range of research, practice, and policy expertise in prevention, wellness, health promotion, and public health. The CPSTF was convened in 1996 by HHS to identify community preventive programs, services, and policies that increase health and longevity, save lives and dollars, and improve Americans' quality of life. CDC is mandated to provide ongoing administrative, research, and technical support for the operations of the CPSTF. During its meetings, the CPSTF considers the findings of systematic reviews of existing research and practice-based evidence, and issues recommendations. CPSTF recommendations are not mandates for compliance or spending. Instead, they provide information about evidence-based options that decision makers and affected community members can consider when they are determining what best meets the specific needs, preferences, available resources, and constraints of their jurisdictions and constituents. The CPSTF's recommendations, along with the systematic reviews of the evidence on which they are based, are compiled on the Community Guide website (
                    <E T="03">www.thecommunityguide.org</E>
                    ).

                     The agenda will consist of deliberation on systematic reviews of literature. Topics proposed for the April 2024 meeting include substance use, public health emergency preparedness and response, oral health, and social determinants of health. Changes regarding the start and end times for each day, and any updates to agenda topics, will be available on the Community Guide website (

                <HD SOURCE="HD1">I. Background and Legislative Authority</HD>
                <P>On October 31, 1988, the Congress enacted the Clinical Laboratory Improvement Amendments of 1988 (Pub. L. 100-578) (CLIA). CLIA amended section 353 of the Public Health Service Act. We issued a final rule implementing the accreditation provisions of CLIA on July 31, 1992 (57 FR 33992). Under those provisions, we may grant deeming authority to an accreditation organization if its requirements for laboratories accredited under its program are equal to or more stringent than the applicable CLIA program requirements in 42 CFR part 493 (Laboratory Requirements). Subpart E of part 493 (Accreditation by a Private, Nonprofit Accreditation Organization or Exemption Under an Approved State Laboratory Program) specifies the requirements an accreditation organization must meet to be approved by CMS as an accreditation organization under CLIA.</P>
                <HD SOURCE="HD1">II. Notice of Re-Approval of COLA as an Accreditation Organization</HD>
                <P>In this notice, we approve COLA as an organization that may accredit laboratories for purposes of establishing their compliance with CLIA requirements for the following specialty and subspecialty areas under CLIA:</P>
                <P>• Microbiology, including Bacteriology, Mycobacteriology, Mycology, Parasitology, and Virology.</P>
                <P>• Diagnostic Immunology, including Syphilis Serology, and General Immunology.</P>
                <P>• Chemistry, including Routine Chemistry, Toxicology, and Endocrinology.</P>
                <P>• Hematology, including routine hematology and coagulation.</P>
                <P>• Immunohematology, including ABO Group, D (Rho) typing, Unexpected Antibody Detection, Compatibility Testing, and Antibody Identification.</P>
                <P>• Pathology, including Histopathology, Oral Pathology, and Cytology.</P>
                <P>
                    We have examined the initial COLA application and all subsequent submissions to determine its accreditation program's equivalency with the requirements for re-approval of an accreditation organization under subpart E of part 493. We have determined that COLA meets or exceeds the applicable CLIA requirements. We have also determined that COLA will ensure that its accredited laboratories will meet or exceed the applicable requirements in subparts H, I, J, K, M, Q, and the applicable sections of R. Therefore, we grant COLA re-approval as an accreditation organization under subpart E of part 493, for the period stated in the 
                    <E T="02">DATES</E>
                     section of this notice for the submitted specialty and subspecialty areas under CLIA. As a result of this determination, any laboratory that is accredited by COLA during the time period stated in the 
                    <E T="02">DATES</E>
                     section of this notice will be deemed to meet the CLIA requirements for the listed subspecialties and specialties, and therefore, will generally not be subject to routine inspections by a State survey agency to determine its compliance with CLIA requirements. The accredited laboratory, however, is subject to validation and complaint investigation surveys performed by CMS, or its agent(s).
                </P>
                <HD SOURCE="HD1">III. Evaluation of COLA's Request for Re-Approval as an Accreditation Organization Under CLIA</HD>
                <P>The following describes the process we used to determine that COLA's accreditation program meets the necessary requirements to be approved by CMS and that, as such, CMS may approve COLA as an accreditation program with deeming authority under the CLIA program. COLA formally applied to CMS for re-approval as an accreditation organization under CLIA for the following specialties and subspecialties:</P>
                <P>• Microbiology, including Bacteriology, Mycobacteriology, Mycology, Parasitology, and Virology.</P>
                <P>
                    • Diagnostic Immunology, including Syphilis Serology, and General Immunology.

                </P>
                <P>• Chemistry, including Routine Chemistry, Toxicology, and Endocrinology.</P>
                <P>• Hematology, including routine hematology and coagulation.</P>
                <P>• Immunohematology, including ABO Group, D (Rho) typing, Unexpected Antibody Detection, Compatibility Testing, and Antibody Identification.</P>
                <P>• Pathology, including Histopathology, Oral Pathology, and Cytology.</P>
                <P>In reviewing these materials, we reached the following determinations for each applicable part of the CLIA regulations:</P>
                <HD SOURCE="HD2">A. Subpart E—Accreditation by a Private, Nonprofit Accreditation Organization or Exemption Under an Approved State Laboratory Program</HD>
                <P>COLA submitted a description of its mechanisms for monitoring compliance with all requirements equivalent to condition-level requirements, a list of all its current laboratories and the expiration date of their accreditation, and a detailed comparison of COLA's individual accreditation requirements with the comparable condition-level requirements. We determined COLA's policies and procedures for oversight of laboratories performing laboratory testing for the submitted CLIA specialties and subspecialties for inspection, monitoring proficiency testing (PT) performance, investigating complaints, and making PT information available, are equivalent to those of CLIA. COLA also submitted descriptions of its infrastructure and procedures for monitoring and inspecting laboratories in the areas of data management, the inspection process, procedures for removal or withdrawal of accreditation, notification requirements for laboratories out of compliance, and accreditation organization resources. We have determined that the requirements of COLA's accreditation program are equal to or more stringent than our requirements of the CLIA regulations.</P>
                <P>Our evaluation determined that COLA requirements regarding waived testing are more stringent than the CLIA requirements at § 493.15(e) that require eligible laboratories to follow the manufacturer's instructions for performing tests and obtain a certificate of waiver as outlined in subpart B, Certificate of Waiver. COLA requires the laboratory director to review quality control results for waived tests monthly and also requires that competency be assessed and documented for personnel performing waived testing.</P>
                <HD SOURCE="HD2">B. Subpart H—Participation in Proficiency Testing for Laboratories Performing Nonwaived Testing</HD>
                <P>We have determined that COLA's requirements are equal to the CLIA requirements at §§ 493.801 through 493.865. Like CLIA, all of COLA's accredited laboratories are required to participate in an HHS-approved PT program for tests listed in subpart I. COLA also encourages its accredited laboratories to participate in PT for tests that are waived under CLIA.  </P>
                <HD SOURCE="HD2">C. Subpart J—Facility Administration for Nonwaived Testing</HD>
                <P>We have determined that COLA's requirements are equal to the CLIA requirements at §§ 493.1100 through 493.1105.</P>
                <HD SOURCE="HD2">D. Subpart K—Quality System for Nonwaived Testing</HD>
                <P>We have determined that COLA's requirements are equal to the CLIA requirements at §§ 493.1200 through 493.1299.</P>
                <HD SOURCE="HD2">E. Subpart M—Personnel for Nonwaived Testing</HD>
                <P>We have determined that COLA's requirements are equal to the CLIA requirements at §§ 493.1403 through 493.1495 for laboratories that perform moderate and high complexity testing.</P>
                <HD SOURCE="HD2">F. Subpart Q—Inspection</HD>
                <P>We have determined that COLA's requirements are equal to the CLIA requirements at §§ 493.1771 through 493.1780. COLA will continue to conduct biennial onsite inspections. An unannounced inspection would be performed when a complaint, lodged against a laboratory accredited by COLA, indicates that problems may exist within the laboratory that may have a serious or immediate impact on patient care.</P>
                <HD SOURCE="HD2">G. Subpart R—Enforcement Procedures</HD>
                <P>We have determined that COLA meets the requirements of subpart R to the extent that such requirements apply to accreditation organizations. COLA policy sets forth the actions the organization takes when laboratories it accredits do not comply with its requirements and standards for accreditation. When appropriate, COLA will deny, suspend, or revoke accreditation in a laboratory accredited by COLA and report that action to CMS within 30 days. COLA also provides an appeals process for laboratories that have had accreditation denied, suspended, or revoked.</P>
                <HD SOURCE="HD1">IV. Federal Validation Inspections and Continuing Oversight</HD>
                <P>The Federal validation inspections of laboratories accredited by COLA may be conducted on a representative sample basis or in response to substantial allegations of noncompliance (that is, complaint inspections). The outcome of those validation inspections, performed by CMS or CMS agents, or the State survey agencies, will be our principal means for verifying that the laboratories accredited by COLA remain in compliance with CLIA requirements. This Federal monitoring is an ongoing process.</P>
                <HD SOURCE="HD1">V. Removal of Deeming Authority as an Accreditation Organization</HD>
                <P>CLIA regulations provide that we may withdraw the approval of an accreditation organization, such as that of COLA, before the end of the effective date of approval in certain circumstances, in accordance with § 493.575. If we determine that COLA has failed to adopt, maintain and enforce requirements that are equal to, or more stringent than, the CLIA requirements, or that systemic problems exist in its monitoring, inspection or enforcement processes, we may impose a probationary period 30 days following the date of CMS' determination, not to exceed 1 year, in which COLA would be allowed to address any identified issues, pursuant to our rules at § 493.575(b). Should COLA be unable to address the identified issues, CMS may, in accordance with the applicable regulations, revoke COLA's deeming authority under CLIA.</P>
                <P>
                    Should circumstances result in our withdrawal of COLA's re-approval, we will publish a notice in the 
                    <E T="04">Federal Register</E>

                <P>This information collection supports food safety projects administered by FDA. The FDA's National Retail Food Team conducted a study to measure trends in the occurrence of foodborne illness risk factors, preparation practices, and employee behaviors most commonly reported to the Centers for Disease Control and Prevention as contributing factors to foodborne illness outbreaks at the retail level. Specifically, data was collected in retail and foodservice establishments at 5-year intervals (1998, 2003, and 2008) in order to observe and document trends in the occurrence of the following foodborne illness risk factors:</P>
                <P>• Food from Unsafe Sources,</P>
                <P>• Poor Personal Hygiene,</P>
                <P>• Inadequate Cooking,</P>
                <P>• Improper Holding/Time and Temperature, and</P>
                <P>• Contaminated Equipment/Cross-Contamination.</P>
                <P>
                    FDA developed reports summarizing the findings for each of the three data collection periods, released in 2000, 2004, and 2009.

                    <FTREF/>
                     Data from all three data collection periods were analyzed to detect trends in improvement or regression over time and to determine whether progress had been made toward the goal of reducing the occurrence of foodborne illness risk factors in selected retail and foodservice facility types.

                <P>FDA has approximately 25 Retail Food Specialists (Specialists) who serve as the data collectors for the study. A standard form is used by the Specialists during each data collection. The form is divided into three sections: Section 1—“Establishment Information”; Section 2—“Regulatory Authority Information”; and Section 3—“Foodborne Illness Risk Factor and Food Safety Management System Assessment.” The information in Section 1 “Establishment Information” of the form is obtained during an interview with the establishment owner or person in charge by the Specialist and includes a standard set of questions. The information in Section 2 “Regulatory Authority Information” is obtained during an interview with the program director of the State or local jurisdiction that has regulatory responsibility for conducting inspections for the selected establishment.</P>
                <P>Section 3 includes three parts: Part A for tabulating the Specialists' observations of the food employees' behaviors and practices in limiting contamination, proliferation, and survival of food safety hazards; Part B for assessing the food safety management system being implemented by the facility; and Part C for assessing the frequency and extent of food employee handwashing. The information in Part A is collected from the Specialists' direct observations of food employee behaviors and practices. Infrequent, nonstandard questions may be asked by the Specialists if clarification is needed on the food safety procedure or practice being observed. The information in Part B is collected by making direct observations and asking followup questions of facility management to obtain information on the extent to which the food establishment has developed and implemented food safety management systems. The information in Part C is collected by making direct observations of food employee handwashing. No questions are asked in the completion of Section 3, Part C of the form.</P>
                <P>FDA collects the following information associated with the establishment's identity: establishment name, street address, city, State, ZIP Code, county, industry segment, and facility type. The establishment-identifying information is collected to ensure the data collections are not duplicative. Other information related to the nature of the operation, such as seating capacity and number of employees per shift, is also collected.</P>
                <P>The burden associated with the completion of Sections 1 and 3 of Form FDA 3967 is specific to the persons in charge of the selected facilities. The burden includes the time it will take the person in charge to accompany the data collector during the site visit and answer the data collector's questions. The burden related to the completion of Section 2 of the form is specific to the program directors (or designated individuals) of the respective regulatory authorities. This burden includes the time it will take to answer the data collectors' questions and is the same regardless of the facility type. Data will be consolidated and reported in a manner that does not reveal the identity of any establishment included in the study.</P>
                <P>FDA has collaborated with the Food Protection and Defense Institute to develop a web-based platform in FoodSHIELD to collect, store, and analyze data for the Retail Risk Factor Study. This platform is accessible to State, local, territorial, and tribal regulatory jurisdictions to collect data relevant to their own risk factor studies. Data will be consolidated and reported in a manner that does not reveal the identity of any establishment included in the study. FDA estimates the burden of this collection of information as follows:</P>

                <P>Based on a review of the information collection since our last request for OMB approval, we have made adjustments to our burden estimate. On our own initiative, however, and for efficiency of Agency operations, we are revising the information collection to include and consolidate related information collection found in 0910-0799. Therefore, our estimated burden for the information collection reflects an increase of 1,401 total burden hours and a corresponding increase of 808 total annual responses.</P>

                <P>In compliance with 44 U.S.C. 3507, FDA has submitted the following proposed collection of information to OMB for review and clearance.</P>
                <HD SOURCE="HD1">Applications for FDA Approval To Market a New Drug—21 CFR Part 314</HD>
                <HD SOURCE="HD2">OMB Control Number 0910-0001—Revision</HD>
                <P>This information collection supports implementation of statutory and regulatory authorities that govern new drugs. Under section 505(a) of the Federal Food, Drug, and Cosmetic Act (FD&amp;C Act) (21 U.S.C. 355(a)), a new drug may not be commercially marketed in the United States unless an approval of an application filed with FDA under section 505(b) or (j) of the FD&amp;C Act is effective with respect to such drug. We have issued regulations in part 314 (21 CFR part 314) that establish procedures and requirements for applications submitted in accordance with section 505 of the FD&amp;C Act. The regulations in subpart A (§§ 314.1 through 314.3) set forth general provisions, while regulations in subparts B and C (§§ 314.50 through 314.99) set forth content and format requirements for new drug applications (NDAs) and abbreviated new drug applications (ANDAs) respectively. The regulations include requirements for the submission of specific data elements along with patent information, pediatric use information, supplements and amendments, proposed labeling, and specific postmarketing reports (PMRs). Respondents to the information collection are sponsors of these applications.</P>
                <P>
                    Regulations in subpart D (§§ 314.100 through 314.170) explain Agency actions on applications and set forth timeframes for FDA review. The information collection includes provisions established through our Agency user fee programs, most recently authorized under the FDA User Fee Reauthorization Act of 2022. These provisions pertain to performance goals, expedited programs, review transparency, communications with FDA, dispute resolution, drug safety enhancements, and the allocation of Agency resources to align with these program objectives as agreed to with our stakeholders and set forth in our “User Fee Performance Goals for Fiscal Years 2023-2027” Commitment Letters, which are available from our website at 
                    <E T="03">https://www.fda.gov</E>
                     along with more information about specific FDA user fee programs.
                </P>
                <P>
                    Included among the provisions in subpart G (§§ 314.410 through 314.445), § 314.420 covers information to include in drug master files (DMFs). To assist respondents to this information collection we have prepared templates, guidance, forms, and resources available from our website at 
                    <E T="03">https://www.fda.gov/drugs/forms-submission-requirements/drug-master-files-dmfs.</E>
                     We have developed Form FDA 3938 and accompanying instructions on submitting DMFs in accordance with the applicable regulations. We are revising Form FDA 3898 and the accompanying instructions to allow for multiple selections of submission types and to clarify the number of digits to be entered for the holder and establishment registration numbers.
                </P>
                <P>
                    In accordance with § 314.445, we also develop Agency guidance documents to assist respondents in complying with provisions in part 314. These guidance documents are issued consistent with our good guidance practice regulations at 21 CFR 10.115. To search available FDA guidance documents, visit our website at 
                    <E T="03">https://www.fda.gov/regulatory-information/search-fda-guidance-documents.</E>
                </P>
                <P>Applications submitted in accordance with subpart H (§§ 314.500 through 314.560) pertain to accelerated approval of new drugs for serious or life-threatening illnesses.</P>
                <P>Information collection and associated burden for the submissions in subpart I (§§ 314.600 through 314.650) pertain to approval of certain new drugs when human efficacy studies are not ethical or feasible. The regulations provide for the submission of specific data elements, animal studies of safety and efficacy to establish likely clinical benefit in humans and upon approval of the drug product, additional requirements and/or restrictions to ensure safe use of the product. Additional PMRs, safety reporting, and promotional material as well as requirements for withdrawal of these human drug applications, and FDA termination of requirements for these human drug applications are included in §§ 314.620 through 314.650. The estimated burden for these human drug applications is included in the reported submissions and burden under general human drug applications, § 314.50, and other specific regulations in the table for human drug application requirements in general.</P>
                <P>
                    Finally, we are also revising the collection to include the submission of information pursuant to the CREATES Act (enacted as part of the Further Consolidated Appropriations Act of 2020 (21 U.S.C. 355-1(1) and 355-2)). Under the CREATES Act, developers of potential drug and biological products are enabled to use the CREATES pathway to obtain samples of brand products that are needed to support their applications. Relevant products include those submitted in generic drug applications under section 505(j) of the FD&amp;C Act and NDAs submitted under 
                    <PRTPAGE P="16000"/>
                    section 505(b)(2) of the FD&amp;C Act, and biosimilar products submitted under section 351(k) of the Public Health Service Act as amended by the Biologics Price Competition and Innovation Act of 2009. One of the requirements for using the CREATES pathway for products that are subject to a Risk Evaluation and Mitigation Strategy with elements to assure safe use is to obtain a Covered Product Authorization (CPA) from FDA (21 U.S.C. 355-2(b)(2)). Included in our estimated burden is effort we attribute to information collection activities associated with CPAs.

                <P>Our estimated burden for the information collection reflects an overall decrease of 642,293.5 hours. The reporting period for this information collection renewal includes the 3 years of the COVID-19 pandemic. We attribute this adjustment to a decrease in the number of submissions received during the public health emergency. We anticipate that the numbers of submissions to FDA will return to pre-pandemic levels as economic activity recovers. We also attribute a portion of the burden adjustment to improved operational efficiencies with regard to Agency data systems and digital submission processes.</P>

                <HD SOURCE="HD1">I. Background</HD>
                <P>On January 31, 2014, FDA approved new drug application (NDA) 205677 for HETLIOZ (tasimelteon) for treatment of non-24-hour sleep-wake disorder, a circadian-rhythm disorder that disproportionately afflicts individuals who are totally blind. On October 16, 2018, Vanda submitted the supplemental NDA (sNDA) that is the subject at issue here: sNDA 205677-004 for HETLIOZ (tasimelteon) capsules, 20 mg, proposing to add a new indication for the treatment of jet lag disorder. On December 1, 2020, FDA approved NDA 214517 for HETLIOZ (tasimelteon) suspension for the treatment of nighttime sleep disturbances in pediatric patients with Smith-Magenis Syndrome, a rare genetic neurodevelopment disorder.</P>
                <P>
                    On July 1, 2022, Vanda requested an opportunity for a hearing under 21 CFR 314.110(b)(3) on whether there are grounds under section 505(d) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(d)) for denying approval of sNDA 205677-004 for the treatment of jet lag disorder. On August 29, 2022, CDER notified Vanda by registered mail, providing it with a notice of opportunity for a hearing (NOOH) on a proposal to refuse to approve sNDA 205677-004. The NOOH was subsequently published in the 
                    <E T="04">Federal Register</E>
                     of October 11, 2022 (87 FR 61337).
                </P>
                <P>On November 10, 2022, Vanda filed a notice of participation and requested a hearing and, on December 12, 2022, submitted information, data, and analyses in support of that request. On June 12, 2023, CDER submitted a proposed order denying Vanda's request for a hearing and refusing to approve the sNDA. On August 11, 2023, Vanda responded to CDER's proposed order. On September 8, 2023, CDER submitted a reply, which included a revised proposed order.</P>
                <P>After considering the parties' submissions, on March 1, 2024, FDA issued a decision denying Vanda's request for a hearing on CDER's proposal to refuse approval and refusing to approve sNDA 205677-004.</P>

                <P>This information collection supports Agency outreach and other proactive communication efforts. Evaluating communication messages and supporting materials in advance of a communication campaign provides an important role in improving FDA communications as they allow for an indepth understanding of individuals knowledge, attitudes, beliefs, motivations, feelings, and behaviors. Such evaluations are critical in helping FDA develop public health communications that meet the needs and desires of its many diverse target audiences.</P>
                <P>We intend to use the following methods with general public health consumers and healthcare professionals in our efforts: individual indepth interviews, focus group discussions, intercept interviews, self-administered surveys, and gatekeeper surveys, all on a voluntary basis. The methods to be used serve the narrowly defined need for direct and informal opinion on a specific topic and, as a qualitative and/or quantitative research tools, have two major purposes: (1) to obtain information that is useful for developing variables and measures for formulating the basic objectives of risk communication campaigns and (2) to assess the potential effectiveness of messages and materials in reaching and successfully communicating with their intended audiences. We will use these methods to test and refine our ideas and to help develop messages and other communications but will generally conduct further research before making important decisions, such as adopting new policies and allocating or redirecting significant resources to support these policies.</P>
                <P>We will use this qualitative and/or quantitative research to test messages about regulated drug products on a variety of subjects related to consumer, patient, or healthcare professional perceptions and about use of drug products and related materials, including but not limited to: (1) direct-to-consumer prescription drug promotion; (2) labeling and information about prescription and over-the-counter drugs; (3) patient medication guides; (4) safety and risk communications; (5) online sale of medical products; and (6) consumer and professional education. Annually, we project about 75 communication studies using the variety of research methods listed in this document. FDA is requesting an extension of these burden hours so as not to restrict its ability to gather information on public opinion for its regulatory and communications programs.</P>

                <P>We are announcing the availability of a guidance for industry entitled “Dietary Supplements: New Dietary Ingredient Notification Procedures and Timeframes: Guidance for Industry.” We are issuing this guidance consistent with our good guidance practices regulation (21 CFR 10.115).

                    In the 
                    <E T="04">Federal Register</E>
                     of July 5, 2011 (76 FR 39111), we announced the availability of a draft guidance for industry entitled “Draft Guidance for Industry; Dietary Supplements: New Dietary Ingredient Notifications and Related Issues” and gave interested parties an opportunity to submit comments by October 3, 2011. Among other topics, the July 2011 draft guidance discussed FDA's views and recommendations on when an ingredient intended for use in a dietary supplement is a new dietary ingredient (NDI), when the requirement to submit a new dietary ingredient notification (NDIN) to FDA applies, the types of data and information that manufacturers and distributors should consider when they 
                    <PRTPAGE P="16004"/>
                    evaluate the safety of a dietary supplement containing an NDI, what to include in an NDIN (including recommendations about identity and safety information), and the procedures for submitting an NDIN. We received significant comments and decided to issue a revised draft guidance.

                    In the 
                    <E T="04">Federal Register</E>
                     of August 12, 2016 (81 FR 53486), we announced the availability of a revised draft guidance for industry entitled “Dietary Supplements: New Dietary Ingredient Notifications and Related Issues; Revised Draft Guidance for Industry” to replace the July 2011 draft guidance. In the notice of availability, we gave interested parties an opportunity to submit comments on the 2016 revised draft guidance by October 11, 2016. On October 4, 2016, we extended the comment period for the revised draft guidance to December 12, 2016 (81 FR 68434). We received numerous comments on the 2016 revised draft guidance, including requests for FDA to separate the 2016 revised draft guidance into discrete sections for ease of use. The final guidance whose availability we are announcing through this document reflects that approach. The guidance finalizes Section V of the 2016 revised draft guidance, “NDI Notification Procedures and Timeframes,” as well as several related questions from other sections. Changes since the revised draft guidance include providing the following: additional clarity on the procedures for preparing and submitting an NDIN; technical updates related to recent changes to our online submission portal for NDINs; and more information about communications with FDA during the NDIN review process. In addition, we made editorial changes to improve clarity. We understand the importance of finalizing other parts of the 2016 revised draft guidance, and we plan to finalize other individual sections as we complete our review and analysis of those sections.

                    Section 100.2 of the VICP's implementing regulation (42 CFR part 100) states that the revised amount of an average cost of a health insurance policy, as determined by the Secretary of Health and Human Services (the Secretary), is effective upon its delivery by the Secretary to the United States Court of Federal Claims (the Court) and will be published periodically in a notice in the 
                    <E T="04">Federal Register</E>
                    . This responsibility has been delegated to the Director, Division of Injury Compensation Programs. This figure is calculated using the most recent Medical Expenditure Panel Survey—Insurance Component data available as the baseline for the average monthly cost of a health insurance policy. This baseline is adjusted by the annual percentage increase/decrease obtained from the most recent annual Kaiser Family Foundation Employer Health Benefits Survey.
                </P>
                <P>
                    In 2023, the Medical Expenditure Panel Survey—Insurance Component, available at 
                    <E T="03">www.meps.ahrq.gov,</E>
                     published the annual 2022 average total single premium per enrolled employee at private-sector establishments that provide health insurance. The figure published was $7,590. This figure is divided by 12 to determine the cost per month of $632.50. The $632.50 figure is increased or decreased by the percentage change reported by the most recent Kaiser Family Foundation Employer Health Benefits Survey, available at 
                    <E T="03">www.kff.org.</E>
                     The increase from 2022 to 2023 was 7 percent. By adding this percentage increase, the calculated average monthly cost of a health insurance policy for a 12-month period is $676.78.
                </P>
                <P>Therefore, the Secretary announces that the revised average cost of a health insurance policy under the VICP is $676.78 per month. In accordance with section 100.2, the revised amount was effective upon its delivery by the Secretary to the Court. Such notice was delivered to the Court on February 23, 2024.</P>

                <P>The Request for Information was published on December 4, 2023. 88 FR 84157. The original comment period will close on March 4, 2024. However, the Coast Guard has been notified that several stakeholders would like more time to prepare their comments for the Request for Information. The Coast Guard has decided that an extension of the public comment period would be appropriate to allow interested parties additional time to submit comments for Coast Guard's consideration. Thus, Coast Guard is extending the comment period by 60 days, until May 3, 2024.</P>

                <P>In 1876, human remains representing, at minimum, six individuals were removed from Alton in Madison County, IL, by Reverend Robert West. Artifacts recovered from this informal excavation were later transferred to William Letchworth at an unknown point. The 29 associated funerary objects are 27 bones (identified as belonging to a white-tailed deer that represent at least four adults and two immature deer), one whale cervical vertebral body, and one black stone/ceramic pipe stem fragment (approx.10mm in length).</P>

                <HD SOURCE="HD1">Abstract of Information Available</HD>
                <P>One cultural item has been requested for repatriation. The object is a bear claw necklace, consisting of a small leather thong or strap, which is threaded through punctured holes in each of two bear claws. This necklace was originally in the collection of Townsend Bishop (1867-1950) of Colliersville, NY. It is unclear how Mr. Bishop acquired this necklace. This collection was purchased by Rowan Spraker Sr. of Cooperstown, NY, before joining the Yager Museum's collection in 1963. Museum records indicate that this necklace was made by the Ute, and subsequent research and consultation has supported this affiliation, as well as the culturally patrimonial status of this object to the Ute people.</P>

                    Human remains representing, at minimum, one individual were removed from Marinette County, WI. In 1964, historic burials were excavated at the Potato Rapids site (47-MT-79) located along the Peshtigo River just upstream of the Highway-64 Bridge near the town of Peshtigo and the Potato Rapids power plant in Porterfield Township, 
                    <PRTPAGE P="16014"/>
                    Marinette County, WI. Members of the Wisconsin Archaeological Society conducted the excavations under the supervision of Robert J. Hruska, then Curator of Anthropology at the Oshkosh Public Museum. The individual was then donated to the Milwaukee Public Museum by Hruska and the Wisconsin Archaeological Society on June 6th, 1967. The individual is a complete female that has associated funerary objects in a suspended matrix within a plaster jacket and two metal poles attached along the length serve as handles for transport. The 12 associated funerary objects include birch bark fragments, two silver brooches, one lot of black glass beads (&gt;50), fabric fragments, a metal cup, a belt buckle, a knife handle or pocketknife, a saucer or plate, brooch or gorget, metal fragments, and fur fragments.
                </P>
                <P>The Potato Rapids Burial site (47-MT-79) is located within the ancestral territory of the Menominee Indian Tribe of Wisconsin and within the area occupied by the Menominee during the early to mid-19th century. According to the Treaty with the Menominee of 1836, a section of land including the site was ceded by the Menominee to the United States Federal Government. Additionally, a map of Indian Villages c. 1830 in the Wisconsin Region of Michigan Territory from Helen Hornbeck Tanner's book, “Atlas of Great Lakes Indian History”, shows several Menominee villages located in the vicinity of the site. In 2000, a burial from the same site was affiliated with and repatriated to the Menominee Indian Tribe of Wisconsin by the Oshkosh Public Museum.</P>

                <HD SOURCE="HD1">Description</HD>
                <P>Human remains representing, at minimum, one individual were removed from an unknown geographic location in AR. The individual (V-MAN-0215) was collected on an unknown date and was obtained by Raymond C. Vietzen (1907-1995). Vietzen, an avocational archeologist, collector, and author, established the Indian Ridge Museum in Elyria, Ohio, and the Archaeological Society of Ohio (formerly the Ohio Indian Relic Collectors Society). The Indian Ridge Museum, founded in the 1930s, served as Vietzen's laboratory and repository, and it remained in operation until the mid-1990s. After Vietzen's death, the facility fell into disrepair, and most of the items he had acquired and housed at the museum were sold. In 1998, the Ohio Historical Society (presently the Ohio History Connection) removed ancestral human remains and some of the remaining items from the facility and temporarily housed them at the Ohio Historical Society. In October of 2003, these human remains were transferred from the Ohio Historical Society to Mercyhurst College (presently Mercyhurst University). No associated funerary objects are present.</P>

                <HD SOURCE="HD1">Description</HD>
                <P>Human remains representing, at minimum, one individual were removed from Crawford County, AR. The individual (VM-079) was collected on an unknown date and was obtained by Raymond C. Vietzen (1907-1995). Vietzen, an avocational archeologist, collector, and author, established the Indian Ridge Museum in Elyria, Ohio, and the Archaeological Society of Ohio (formerly the Ohio Indian Relic Collectors Society). The Indian Ridge Museum, founded in the 1930s, served as Vietzen's laboratory and repository, and it remained in operation until the mid-1990s. After Vietzen's death, the facility fell into disrepair and most of the items he had acquired and housed at the museum were sold. In 1998, the Ohio Historical Society (presently the Ohio History Connection) removed ancestral human remains and some of the remaining items from the facility and temporarily housed them at the Ohio Historical Society. In October of 2003, these human remains and items were transferred from the Ohio Historical Society to Mercyhurst College (presently Mercyhurst University). No associated funerary objects are present.</P>
                <HD SOURCE="HD1">Cultural Affiliation</HD>
                <P>The human remains in this notice are connected to one or more identifiable earlier groups, tribes, peoples, or cultures. There is a relationship of shared group identity between the identifiable earlier groups, tribes, peoples, or cultures and one or more Indian Tribes or Native Hawaiian organizations. The following types of information were used to reasonably trace the relationship: geographical, linguistics, and oral tradition.</P>
                <HD SOURCE="HD1">Determinations</HD>
                <P>Pursuant to NAGPRA and its implementing regulations, and after consultation with the appropriate Indian Tribes and Native Hawaiian organizations, Mercyhurst University has determined that:</P>
                <P>• The human remains described in this notice represent the physical remains of one individual of Native American ancestry.</P>
                <P>• There is a relationship of shared group identity that can be reasonably traced between the human remains described in this notice and the Caddo Nation of Oklahoma and The Osage Nation.</P>

                    A total of seven cultural items have been requested for repatriation. The sacred objects/objects of cultural patrimony are five basket hats, one basket with a lid, and one basket. The seven cultural items were removed from an unknown county and state, likely originating from Northern California and/or Southern Oregon. In 1983, a private individual donated five of the objects of cultural patrimony/sacred objects (four basket hats, one basket with lid) to DOMA. These are identified by DOMA catalog numbers 1983.006.003, 1983.006.004a, 1983.006.004b, 1983.006.005a-b, and 1983.006.059. In 2018, the estate of a private individual bequeathed two of the objects of cultural patrimony/sacred objects (one basket hat and one basket) to DOMA. These are identified by DOMA catalog numbers 2018.052.022 and 2018.052.024. No information is available for any of the objects concerning the dates of creation, donor

                <HD SOURCE="HD1">Description</HD>
                <P>Human remains representing, at minimum, five individuals were removed from Washoe County, NV. The human remains consisted of five incomplete individuals: one adult male; one young adult male approximately 20-35 years old; one young adult male; one youth, possibly male, approximately 15-20 years old; and one child. These human remains were originally cataloged by the Hearst Museum under Accession 1030 and their catalog number is 12-8369. At the request of the Pyramid Lake Paiute Tribe, these human remains were transferred to the Nevada State Museum (NSM) in 2012. The NSM catalog numbers for the human remains are AHUR 6019 through 6023.</P>
                <P>The Bureau of Land Management recently became aware of Native American human remains collected prior to November 16, 1990, on lands administered by the BLM. The human remains were reported as culturally unidentifiable on June 19, 2003, by the Phoebe A. Hearst Museum of Anthropology (Hearst Museum). In November 2011, the BLM became aware of previously unreported Native American human remains through a letter from the Pyramid Lake Paiute Tribe requesting BLM involvement in assisting with the repatriation of remains being held at the Hearst Museum. The remains were collected sometime in 1947-1948 near Winnemucca Lake Caves in Nevada and received by the Hearst Museum in 1948. According to the records of the Hearst Museum, this material was reported in their Washoe County Inventory, dated June 28, 2000. In a closer review of the locality documentation, it was determined the material is under the control of the BLM.</P>

                <P>Human remains representing, at minimum, one individual were removed from Yakima County, WA. The Yakima County Coroner's Office found the human remains in 2000 or 2001 and subsequently donated them to Central Washington University. The Coroner's Office has no information about their origins. The King County Medical Examiner's Forensic Anthropologist determined the human remains to be non-forensic. No associated funerary objects are present.</P>

                <P>The human remains in this notice are connected to one or more identifiable earlier groups, tribes, peoples, or cultures. There is a relationship of shared group identity between the identifiable earlier groups, tribes, peoples, or cultures and one or more Indian Tribes or Native Hawaiian organizations. The following types of information were used to reasonably trace the relationship: biological, geographical, historical, and expert opinion.</P>

                <P>A total of two cultural items have been requested for repatriation. The two objects of cultural patrimony are a robe and a mat. J.A. Wyrick and Frank Weddington removed these items from Piney Creek Bluff Shelter in Carroll County, AR in 1935. Harry Lemley acquired these from them later that same year. Thomas Gilcrease purchased Lemley's collection, including these items, in 1950, and Gilcrease transferred his collection to the City of Tulsa in 1955.</P>
                <P>A total of one cultural item has been requested for repatriation. The one object of cultural patrimony is a bald cypress pole fragment. James Porter removed the item from the Mitchell Mound site in Madison County, Illinois in the 1960s. Gilcrease Museum acquired the item shortly after.</P>
                <HD SOURCE="HD1">Determinations</HD>
                <P>The Gilcrease Museum has determined that:</P>
                <P>• The three objects of cultural patrimony described in this notice have ongoing historical, traditional, or cultural importance central to the Native American group, including any constituent sub-group (such as a band, clan, lineage, ceremonial society, or other subdivision), according to the Native American traditional knowledge of an Indian Tribe or Native Hawaiian organization.</P>

Supplements were filed on February 19, 2024, February 20, 2024, and February 21, 2024. The complaint alleges violations of section 337 based upon the importation into the United States, the sale for importation, and the sale within the United States after importation of certain oil vaporizing devices, components thereof, and products containing the same by reason of the infringement of certain claims of U.S. Patent No. 11,369,756 (“the '756 patent”); U.S. Patent No. 11,369,757 (“the '757 patent”); U.S. Patent No. 11,766,527 (“the '527 patent”); 11,759,580 (“the '580 patent”). The complaint further alleges that an industry in the United States exists as required by the applicable Federal Statute. The complainant requests that the Commission institute an investigation and, after the investigation, issue a limited exclusion order and a cease and desist order.</P>

                    The products covered by these investigations are all types of youth and adult mattresses. The term “mattress” denotes an assembly of materials that at a minimum includes a “core,” which provides the main support system of the mattress, and may consist of innersprings, foam, other resilient filling, or a combination of these materials. Mattresses also may contain: (1) “upholstery,” the material between the core and the top panel of the ticking on a single-sided mattress, or between the core and the top and bottom panel of the ticking on a double-sided mattress; and/or (2) “ticking,” the outermost layer of fabric or other material (

                     vinyl) that encloses the core and any upholstery, also known as a cover.

                <HD SOURCE="HD1">I. Background</HD>
                <P>
                    The Department of Labor, as part of the continuing effort to reduce paperwork and respondent (
                    <E T="03">i.e.,</E>
                     employer) burden, conducts a preclearance consultation program to provide the public with an opportunity to comment on proposed and continuing information collection requirements in accordance with the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3506(c)(2)(A)). This program ensures that information is in the desired format, reporting burden (time and costs) is minimal, the collection instruments are clearly understood, and OSHA's estimate of the information collection burden is accurate. The Occupational Safety and Health Act of 1970 (OSH Act) (29 U.S.C. 651 
                    <E T="03">et seq.</E>
                    ) authorizes information collection by employers as necessary or appropriate for enforcement of the OSH Act or for developing information regarding the causes and prevention of occupational injuries, illnesses, and accidents (29 U.S.C. 657). The OSH Act also requires that OSHA obtain such information with minimum burden upon employers, especially those operating small businesses, and to reduce to the maximum extent feasible unnecessary duplication of effort in obtaining information (29 U.S.C. 657).
                </P>
                <P>The Fire Protection in Shipyard Employment Standard specifies a number of information collection requirements. In general, the standard requires employers to develop a written fire safety plan covering elements that identify the potential fire risk hazards and procedures for reporting these hazards, employers to create, maintain, and update a written policy that describes the internal and outside fire response organizations that the employer will use, and employers to notify employees and take the necessary precautions to make sure employees are safe from fire if for any reason a fire extinguishing system stops working. The standard also requires the employer to obtain medical exams for certain workers and to create and maintain records to certify that employees have been made aware of the details of the fire safety plan and that employees have been trained as required by the standard.</P>
                <HD SOURCE="HD1">II. Special Issues for Comment</HD>
                <P>OSHA has a particular interest in comments on the following issues:</P>
                <P>• Whether the proposed information collection requirements are necessary for the proper performance of the agency's functions to protect workers, including whether the information is useful;</P>
                <P>• The accuracy of OSHA's estimate of the burden (time and costs) of the information collection requirements, including the validity of the methodology and assumptions used;</P>
                <P>• The quality, utility, and clarity of the information collected; and</P>
                <P>• Ways to minimize the burden on employers who must comply; for example, by using automated or other technological information, and transmission techniques.</P>
                <HD SOURCE="HD1">III. Proposed Actions</HD>
                <P>OSHA is requesting that OMB extend the approval of the information collection requirements specified in the Fire Protection in Shipyard Employment Standard. The agency is requesting an adjustment decrease in burden from 16,251 to 15,972 hours, a difference of 279 hours. This decrease in burden is due to the decrease in the number of affected workers and in the number of establishments.</P>
                <P>OSHA will summarize the comments submitted in response to this notice and will include this summary in the request to OMB to extend the approval of the information collection requirements.</P>

                     The National Credit Union Administration (NCUA) Federal Credit Union Act, 12 U.S.C. 1757(7), 1757(8), 1757(15), lists securities, deposits, and other obligations in which a Federal Credit Union (FCU) may invest. The regulations related to these areas are contained in Part 703 and Section 721.3 of the NCUA Rules and Regulations, which set forth requirements related to maintaining an adequate investment program. The information collected is used by the NCUA to determine compliance with the appropriate sections of the NCUA Rules and Regulations and FCU Act, which governs investment and deposit activities on the basis of safety and soundness concerns. It is used to determine the level of risk that exists within a credit union, the actions taken by the credit union to mitigate such risk, and helps prevent losses to federal credit unions and the National Credit Union Share Insurance Fund (NCUSIF).

The NCUA Board issued Interpretive Ruling and Policy Statement (IRPS) 13-1 establishing a MDI preservation program to comply with FIRREA § 308 goals. The IRPS identifies the procedure for a federally insured credit union to determine and document its ability to designate itself as a MDI, resulting in the ability to participate in the Program.

                        The U.S. Nuclear Regulatory Commission (NRC) is requesting comment on a draft Programmatic Agreement (PA) between the NRC, Pennsylvania State Historic Preservation Office (SHPO), and TMI-2 Energy Solutions (TMI-2

                        ). The purpose of this draft PA is to resolve any adverse effects to historic properties identified during consultation for a license amendment request for the Three Mile Island Nuclear Station, Unit No. 2 (TMI-2), located in Londonderry Township, Dauphin County, Pennsylvania. TMI-2

                         will be engaging in certain major decommissioning activities, including the physical demolition of buildings previously deemed eligible for the National Register of Historic Places (NRHP). Because the impacts on the historic properties from these decommissioning activities have not been previously evaluated and are not bounded by NUREG-0586, “Final Generic Environmental Impact Statement (GEIS) on Decommissioning of Nuclear Facilities”, the NRC initiated consultation under the National Historic Preservation Act (NHPA). During the NHPA section 106 consultation, it was determined that there would be adverse effects to historic properties and a PA was developed to address resolution of adverse effects.

                    By letter dated February 22, 2023 (ADAMS Accession No. ML23058A064), TMI-2
                    <E T="03">Solutions</E>
                     requested an amendment to Possession Only License No. DPR-73. TMI-2
                    <E T="03">Solutions</E>
                     will be engaging in certain major decommissioning activities, including the physical demolition of buildings previously deemed eligible for the National Register of Historic Places (NRHP). Paragraph 50.82(a)(6)(ii) of title 10 of the 
                    <E T="03">Code of Federal Regulations</E>
                     (10 CFR) states that licensees shall not perform any decommissioning activities that would result in significant environmental impacts that have not been previously reviewed. Adverse impacts, such as certain alterations or demolition to structures that have been deemed eligible for listing on the NRHP, could be considered unreviewed significant environmental impacts under 10 CFR 50.82(a)(6)(ii). Because the impacts on the historic properties from TMI-2
                    <E T="03">Solutions'</E>
                     proposed decommissioning activities have not been previously evaluated, TMI-2
                    <E T="03">Solutions</E>
                     requested an amendment to evaluate the impacts of the decommissioning activities on the NRHP-eligible properties.
                </P>
                <P>The NRC uses its National Environmental Policy Act process for developing environmental assessments (EAs) to facilitate consultation under section 106 of the National Historic Preservation Act (NHPA), pursuant to 36 CFR 800.8.</P>
                <P>
                    The NRC met with the Advisory Council on Historic Preservation, the Pennsylvania State Historic Preservation Officer (SHPO), TMI-2
                    <E T="03">Solutions,</E>
                     and other consulting parties to discuss how to address the adverse effects to historic properties. The parties agreed to develop a PA to resolve any adverse effects. As explained in the PA, once the agreement is executed, the NRC will become the lead agency for implementation of the PA.
                </P>
                <P>The draft PA addresses the potential direct and indirect adverse effects from the decommissioning activities and ensures that appropriate mitigation measures are implemented. The NRC's final EA will include the final PA and therefore conclude NHPA section 106 consultation.</P>

                <P>Under section 2 of the Railroad Retirement Act (45 U.S.C. 231a), dependency on an employee for one-half support at the time of the employee's death can affect (1) entitlement to a survivor annuity when the survivor is a parent of the deceased employee; (2) the amount of spouse and survivor annuities; and (3) the Tier II restored amount payable to a widow(er) whose annuity was reduced for receipt of an employee annuity, and who was dependent on the railroad employee in the year prior to the employee's death. One-half support may also negate the public service pension offset in Tier I for a spouse or widow(er). The Railroad Retirement Board (RRB) utilizes Form G-134, Statement Regarding Contributions and Support, to secure information needed to adequately determine if the applicant meets the one-half support requirement. One response is completed by each respondent. Completion is required to obtain benefits. The RRB proposes a minor editorial changes to Form G-134 to change the date under section 1 “General Instructions”.</P>

                <P>Under section 10 of the Railroad Retirement Act and section 2(d) of the Railroad Unemployment Insurance Act (45 U.S.C. 231i), the RRB may recover overpayments of annuities, pensions, death benefits, unemployment benefits, and sickness benefits that were made erroneously. An overpayment may be waived if the beneficiary was not at fault in causing the overpayment and recovery would cause financial hardship. The regulations for the recovery and waiver of erroneous payments are contained in 20 CFR 255 and CFR 340.</P>
                <P>The RRB utilizes Form DR-423, Financial Disclosure Statement, to obtain information about the overpaid beneficiary's income, debts, and expenses if that person indicates that (s)he cannot make restitution for the overpayment. The information is used to determine if the overpayment should be waived as wholly or partially uncollectible. If waiver is denied, the information is used to determine the size and frequency of installment payments. The beneficiary is made aware of the overpayment by letter and is offered a variety of methods for recovery. One response is requested of each respondent. Completion is voluntary. However, failure to provide the requested information may result in a denial of the waiver request. The RRB proposes no changes to Form DR-423.</P>

                <P>Under section 12 of the Railroad Retirement Act (RRA) (45 U.S.C. 231k), the RRB may pay annuity benefits to a representative payee when an employee, spouse, or survivor annuitant is incompetent or a minor. The RRB is responsible for determining if direct payment to an annuitant or a representative payee would best serve the annuitant's best interest. The accountability requirements authorizing the RRB to conduct periodic monitoring of representative payees, including a written accounting of benefit payments received, are prescribed in 20 CFR 266.7. The RRB utilizes the following forms to conduct its representative payee monitoring program.</P>
                <P>
                    Form G-99a, 
                    <E T="03">Representative Payee Report,</E>
                     is used to obtain information needed to determine whether the benefit payments certified to the representative payee have been used for the annuitant's current maintenance and personal needs and whether the representative payee continues to be concerned with the annuitant's welfare. RRB Form G-99c, 
                    <E T="03">Representative Payee Evaluation Report,</E>
                     is used to obtain more detailed information from a representative payee who fails to complete and return Form G-99a or in situations when the returned Form G-99a indicates the possible misuse of funds by the representative payee. Form G-99c contains specific questions concerning the representative payee's performance and is used by the RRB to determine whether or not the representative payee should continue in that capacity. The RRB proposes no changes to Form G-99a or Form G-99c.

Completion of the forms in this collection is required to retain benefits.

                <P>
                    Currently, the Exchange offers a Cabinet Proximity Option program 
                    <PRTPAGE P="16041"/>
                    where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

                         Due to heightened demand for power and cabinets, NYSE established certain procedures related to PNU cabinet conversion and restrictions on new PNU cabinet offerings. NYSE adopted a policy that, if unallocated cabinet inventory is at or below 40 cabinets, new PNU cabinets are not offered. However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>
                <HD SOURCE="HD3">2. Statutory Basis</HD>
                <P>
                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of Section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).
                    <SU>11</SU>
                    <FTREF/>
                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis.

The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (

Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                    On January 11, 2024, the Financial Industry Regulatory Authority, Inc. (“FINRA”) filed with the Securities and Exchange Commission (“Commission”), pursuant to section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
                    <SU>1</SU>

                    proposed rule change to amend FINRA Rule 6730 to reduce the 15-minute TRACE reporting timeframe to one minute, with exceptions for member firms with de minimis reporting activity and for manual trades. The proposed rule change was published for comment in the 
                    <E T="04">Federal Register</E>
                     on January 25, 2024.

                     provides that, within 45 days of the publication of notice of the filing of a proposed rule change, or within such longer period up to 90 days as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or as to which the self-regulatory organization consents, the Commission shall either approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether the proposed rule change should be disapproved. The 45th day after publication of the notice for this proposed rule change is March 10, 2024. The Commission is extending this 45-day time period for Commission action. The Commission finds that it is appropriate to designate a longer period within which to take action on the proposed rule change so that it has sufficient time to consider the proposed rule change and the comments received. Accordingly, pursuant to section 19(b)(2) of the Act, the Commission designates April 24, 2024, as the date by which the Commission shall approve or disapprove, or institute proceedings to determine whether to disapprove, the proposed rule change (File No. SR-FINRA-2024-004).

                    OCC is the issuer of and sole clearing agency for standardized equity options listed on national securities exchanges registered with the Commission. In accordance with OCC's By-Laws, adjustments may be made to some of the standardized terms of outstanding options upon the occurrence of certain events related to the underlying security, such as a stock dividend, stock distribution, stock split, reverse stock split, rights offering, distribution, reorganization, recapitalization, reclassification in respect of an underlying security, or a merger, consolidation, dissolution or liquidation of the issuer of the underlying security.

                     The determination whether to adjust outstanding options in response to a particular event, and, if so, what the adjustment should be, is made by OCC, taking into consideration policies and interpretations established in OCC's By-Laws and any policies and interpretations having general application to specific types of events or specified kinds of cleared contracts established by a committee (the “Securities Committee”) consisting of representatives of each of the U.S. options markets and a representative of OCC.

                     In the interest of promoting clarity and transparency for market participants, OCC is proposing to re-issue that interpretative guidance subject to proposed amendments that would (1) update the interpretative guidance's discussion of how adjustment determinations are made to reflect subsequent changes to the determination process since the interpretative guidance was last issued, and (2) provide additional guidance on certain underlying events.

                         Consistent with prior practice, the interpretative guidance would be issued as an OCC Information Memorandum that would supersede the previously published Information Memoranda related to this interpretative guidance. The Information Memorandum would contain prefatory material intended to provide context for its issuance, remind readers of its relationship to the prior Information Memoranda and this proposed rule change, and summarize the relevant OCC By-Laws that are the subject of the interpretation. OCC does not believe this prefatory material is a rule within the meaning of Section 19(b) of the Exchange Act, 15 U.S.C. 78s(b), and the regulations thereunder because unlike the interpretative guidance promulgated through this proposed rule change, the prefatory material it is not a stated policy, practice or interpretation that establishes or changes any standard, limit, or guideline with respect to the rights, obligations or privileges of specified persons or the meaning, administration, or enforcement of an existing rule.

                    OCC's By-Laws and Rules authorize OCC to make adjustments to listed options when certain events occur related to the underlying security, such as a stock dividend, stock distribution, stock split, reverse stock split, rights offering, distribution, reorganization, recapitalization, or reclassification with respect to the underlying security or the merger, consolidation, dissolution or liquidation of the issuer of the underlying security. The By-Laws provide policies and procedures for making such determinations, including that OCC determines whether to adjust a contract, taking into account such factors as fairness to holders and writers (or purchasers and sellers) of the affected contracts, the maintenance of a fair and orderly market in the affected contracts, consistency of interpretation and practice, efficiency of exercise settlement procedures, and the coordination with other clearing agencies of the clearance and settlement of transactions in the underlying interest.

                    <FTREF/>
                     OCC applies these factors to a particular corporate action on a case-by-case basis, considering the circumstances known to it at the time the determination is made, subject to OCC's discretion to depart from policy and precedent when the Corporation determines that unusual circumstances make such a departure appropriate.

                    OCC's By-Laws also provide general rules applicable to specific types of corporate actions, including with respect to cash dividends or distributions made by the issuer of an underlying security. For example, the By-Laws establish a general rule that OCC does not adjust listed options to reflect “ordinary cash dividends or distributions,” which the By-Laws define to mean “[c]ash dividends or distributions (regardless of size) by the issuer of the underlying security which [OCC] believes to have been declared pursuant to a policy or practice of paying such dividends or distributions on a quarterly or other regular basis or which [OCC] believes represents an acceleration or deferral of such payments.”

                    <FTREF/>
                     OCC established this general rule because when an issuer's policy or practice of paying such dividends is public, such ordinary dividends can be priced into options premiums.

                    <FTREF/>
                     OCC's By-Laws also provide that for cash dividends not declared pursuant to an issuer's policy or practice of paying such distributions at regular intervals (
                    <E T="03">i.e.,</E>
                     “special” cash dividends and distributions), OCC will not adjust if the amount distributed is less than $0.125 per share (or $12.50 per contract for listed options with a unit of trading larger than 100 shares). OCC established this de minimis threshold in part to avoid the proliferation of outstanding option symbols and series.

                    In connection with the adoption of the general rules against adjustments for cash dividends and distributions that are ordinary or below the de minimis threshold, OCC previously filed and published interpretative guidance promulgated by its Securities Committee to address questions about how those rules would be administered and applied.

OCC has since updated and re-issued that interpretative guidance, the last time in 2012.

                <HD SOURCE="HD3">(1) Conforming Changes To Reflect the Current Determination Process</HD>
                <P>
                    The proposed changes would remove references to the adjustment panel of the Securities Committee in the interpretative guidance's discussion of how options adjustments are made. Since the interpretative guidance was last issued in 2012, the Commission approved a proposed rule change that affected the determination process.
                    <SU>17</SU>
                    <FTREF/>
                     Previously, an adjustment panel of the Securities Committee, consisting of representatives from the exchanges on which an option was listed and OCC's Chairman, would make determinations about whether that option should be adjusted in response to a corporate action. Currently, adjustment determinations are made by OCC rather than adjustment panels of the Securities Committee.
                    <SU>18</SU>
                    <FTREF/>
                     However, the Securities Committee still maintains a role in promulgating statements of policy and interpretations having general 
                    <PRTPAGE P="16045"/>
                    application to specified types of corporate actions or specified kinds of cleared contracts.
                    <SU>19</SU>
                    <FTREF/>
                     In making adjustment determinations, OCC must consider such policy statements and interpretations in addition to the factors and general rules set forth in the By-Laws in light of the circumstances known to OCC at the time such determination is made, subject to OCC's discretion to depart from policy or precedent when the OCC determines that unusual circumstances make such a departure appropriate.
                    <SU>20</SU>
                    <FTREF/>
                     OCC assumed sole responsibility for making adjustment determinations after corresponding updates to the Options Disclosure Document were approved by the Commission in 2018.
                    <SU>21</SU>
                    <FTREF/>
                     Accordingly, when OCC re-issues the interpretative guidance on cash dividends and distributions, OCC proposes to replace references to determinations made by an adjustment panel of the Securities Committee with references to OCC and make other non-substantive, textual edits to the interpretative guidance consistent with that change. These changes are intended to reflect the current, Commission-approved process for adjustment determinations made by OCC.

                <HD SOURCE="HD3">(2) Additional Interpretative Guidance</HD>
                <P>OCC also proposes to add additional Q&amp;As that would provide guidance for several situations OCC has observed since the interpretative guidance was last issued, including (a) specific guidance with respect to variable dividends, and (b) additional guidance with respect to dividends issued by real estate investment trusts (“REITs”).</P>
                <HD SOURCE="HD3">a. Variable Dividends</HD>
                <P>OCC has seen an increase in the number of issuers that have established policies or practices of distributing “variable dividends.” Typically, such variable dividends are paid at regular intervals if issuer-defined thresholds for paying the dividends are met. The amount of the variable dividend may increase or decrease (sometimes significantly) from dividend to dividend based on issuer-established thresholds and, on occasion, may not be paid at all if the issuer-established thresholds are not met. These variable dividends may also be in addition to regular dividends paid pursuant to the issuer's policy or practice.</P>
                <P>
                    For example, on May 19, 2022, Arch Resources, Inc. (ARCH) announced an $8.11 quarterly dividend, which included a fixed component of $0.25 and a variable component of $7.86 per share. In making its adjustment determination, OCC considered an ARCH press release, issued on February 15, 2022, communicating that ARCH was launching a capital return program pursuant to which it planned to “return to stockholders approximately 50 percent of the prior quarter's discretionary cash flow . . . via a variable quarterly cash dividend in conjunction with its existing fixed quarterly cash dividend.” 
                    <SU>22</SU>
                    <FTREF/>
                     OCC determined that the quarterly variable dividend was an “ordinary dividend” as defined in Interpretation and Policy .01 to Article VI, Section 11A of OCC's By-Laws, and therefore not subject to adjustment, because the dividend had been declared pursuant to a policy or practice of paying such dividend on a quarterly or other regular basis.

                <P>OCC proposes to add further guidance about situations in which an issuer may pay a dividend outside of its normal schedule of dividend payments that the issuer describes as necessary to maintain its tax status as a particular type of organization, such as a REIT. The existing interpretative guidance answered several questions concerning dividends paid by REITs and similar companies. For example, the existing interpretative guidance addressed that while REITs may pay dividends at irregular intervals, these companies often have regular dividend policies, but will actually pay dividends only when certain conditions are met, or in response to market conditions. Similar to the variable dividend situation, in which, on occasion, no variable dividend is paid if issuer-established thresholds are not met, the prior interpretative guidance provided that such REIT distributions generally would be considered ordinary distributions when they occur pursuant to the policy of the company.</P>
                <P>
                    However, OCC has observed at least one case in which an issuer has declared a dividend outside of its normal schedule of dividend payments to maintain its tax status as a particular type of organization, such as a REIT. Specifically, On July 22, 2022, Public Storage (“PSA”) announced a “special,” “one-time” dividend of $13.15 per common share.

                    <FTREF/>
                     As explained in the issuer's press release, PSA was distributing a projected tax gain in connection with its investment in 
                    <PRTPAGE P="16046"/>
                    another company that had been acquired “in order to meet the distribution requirements as a [REIT].”

                    <FTREF/>
                     Nevertheless, OCC determined that the dividend was non-ordinary under its By-Laws and issued an Info Memo concerning an adjustment to options on PSA.

                <P>As OCC would clarify in the further guidance, such a dividend would most likely be considered non-ordinary and warrant an adjustment if OCC determines that the dividend is not being made pursuant to the issuer's established dividend policies and practices based on the company's departure from its regular dividend schedule and any characterization the company may make about the pay-out as “special” or “one time.” In other words, an issuer's characterization of a dividend as necessary to maintain its tax status as a particular type of organization is not determinative of whether a dividend is “ordinary” under OCC's By-Laws. Rather, the question is whether the dividend is paid pursuant to an issuer's policy of paying such a dividend at regular intervals to maintain its tax status. If such an issuer announces a special dividend outside of its regular dividend policies and practices, such dividend will most likely be considered non-ordinary and warrant an adjustment even if the issuer is paying the dividend to maintain its tax status. OCC proposes to add a Q&amp;A to the interpretative guidance to reflect OCC's practices in this situation.</P>

In addition, OCC believes the additional interpretative guidance would provide investors and the general public further clarity about the application of OCC's adjustment policies and procedures to scenarios not specifically addressed in the existing guidance. Providing this information will help investors make more informed decisions in connection with their participation in the listed options market.

                    Currently, the Exchange offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

                         Due to heightened demand for power and cabinets, NYSE established certain procedures related to PNU cabinet conversion and restrictions on new PNU cabinet offerings. NYSE adopted a policy that, if unallocated cabinet inventory is at or below 40 cabinets, new PNU cabinets are not offered. However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>
                <HD SOURCE="HD3">2. Statutory Basis</HD>
                <P>
                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of Section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).
                    <SU>11</SU>
                    <FTREF/>
                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

                <P>Nothing in the proposal imposes any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis. Use of any colocation service is completely voluntary, and each market participant is able to determine whether to use colocation services based on the requirements of its business operations.  </P>

                     permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (
                    <E T="03">e.g.,</E>
                     greater than 10kW) without delay once a fee is established for such cabinets. The Commission believes that the proposed rule change presents no novel legal or regulatory issues and that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                <P>The Exchange is filing a proposal to amend the Fee Schedule to: (i) apply the Exchange's current Connectivity and Application Session fees to MEMX Options Users, and (ii) make an organizational change to its existing fee schedule for the Exchange's pre-existing equities market (“MEMX Equities”), in order to create a separate fee schedule for Connectivity Fees (for both MEMX Equities and MEMX Options). The Exchange proposes to implement the changes to the Fee Schedule pursuant to this proposal immediately. The text of the proposed rule change is provided in Exhibit 5.</P>

                <P>In its filing with the Commission, the Exchange included statements concerning the purpose of and basis for the proposed rule change and discussed any comments it received on the proposed rule change. The text of these statements may be examined at the places specified in Item IV below. The Exchange has prepared summaries, set forth in sections A, B, and C below, of the most significant aspects of such statements.</P>

                <P>The Exchange is filing a proposal to amend the Fee Schedule to: (i) apply the Exchange's current Connectivity and Application Session fees to MEMX Options Users, and (ii) make an organizational change to its existing fee schedule for the Exchange's pre-existing equities market (“MEMX Equities”), in order to create a separate fee schedule for Connectivity Fees (for both MEMX Equities and MEMX Options). The Exchange believes that these changes will provide greater transparency to Members about how the Exchange assesses fees, as well as allowing Members to more easily validate their bills on a monthly basis. The Exchange notes that none of these changes amend any existing fee applicable to MEMX Equities. The Exchange is proposing to implement the proposal immediately. The Exchange previously filed the proposal on October 24, 2023 (SR-MEMX-2023-29) (the “Initial Proposal”). The Exchange withdrew the Initial Proposal and replaced the proposal with SR-MEMX-2023-39 (the “Second Proposal”). The Exchange recently withdrew the Second Proposal and is replacing it with the current filing (SR-MEMX-2024-06).</P>
                <P>
                    As set forth below, the Exchange believes that its proposal provides a great deal of transparency regarding the cost of providing connectivity services and anticipated revenue and that the proposal is consistent with the Act and associated guidance. The Exchange is re-filing this proposal promptly following the withdrawal of the Second Proposal in order to update the Cost Analysis included in the Second Proposal.

                <P>
                    As noted above, the Exchange is proposing to apply the current fees it charges to Members and non-Members 
                    <SU>3</SU>
                    <FTREF/>
                     for physical connectivity to the Exchange and for application sessions (otherwise known as “logical ports”) that a Member utilizes in connection with their participation on the Exchange (together with physical connectivity, collectively referred to in this proposal as “connectivity services”, as described in greater detail below) to both Users of MEMX Equities and MEMX Options.
                    <SU>4</SU>
                    <FTREF/>
                     Specifically, the Exchange will continue to charge $6,000 per month for a physical connection in the data center where the Exchange primarily operates under normal market conditions (“Primary Data Center”), and $3,000 per month for a physical connection at the geographically diverse data center, which is operated for backup and disaster recovery purposes (“Secondary Data Center”). These physical connections can be used to access both platforms, accordingly, a firm that is a Member of both MEMX Equities and MEMX Options may use a single physical connection to access its application sessions at both MEMX Equities and MEMX Options. This differs from application sessions in that a firm that is a Member of both MEMX Equities and MEMX Options would need to purchase separate application sessions for each trading platform in order to access each such trading platform. These application session fees will continue to be $450 per month for an application session used for order entry (“Order Entry Port”) and $450 per month for an application session for receipt of drop copies (“Drop Copy Port”), to the extent such ports are in the Primary Data Center. As is true today for MEMX Equities, the Exchange will not charge for Order Entry Ports or Drop Copy Ports in the Secondary Data Center. The Exchange's proposal to apply the same fees to Equities and Options stems from the same cost analysis it conducted in adopting those fees to its Equities Members,
                    <SU>5</SU>
                    <FTREF/>
                     which the Exchange has reviewed and updated for 2024 as detailed below. Given that the Exchange has only recently launched MEMX Options, however, and the fact that its analysis is based on projections across all potential revenue streams, the Exchange is committing to conduct a one-year review after these fees are applied. The Exchange expects that it may propose to adjust fees at that time, to increase fees in the event that revenues fail to cover costs, or to decrease fees in the event that revenue materially exceeds expectations.

Service bureaus offer technology-based services to other companies for a fee, including order entry services to Members, and thus, may access application sessions on behalf of one or more Members. Extranets offer physical connectivity services to Members and non-Members.

                </FTNT>
                <P>In general, the Exchange believes that exchanges, in setting fees of all types, should meet very high standards of transparency to demonstrate why each new fee or fee increase meets the Exchange Act requirements that fees be reasonable, equitably allocated, not unfairly discriminatory, and not create an undue burden on competition among members and markets. In particular, the Exchange believes that each exchange should take extra care to be able to demonstrate that these fees are based on its costs and reasonable business needs.</P>
                <P>
                    In proposing to charge fees for connectivity services to MEMX Options, the Exchange has sought to be especially diligent in assessing those fees in a transparent way against its own aggregate costs of providing the related services, and also carefully and transparently assessing the impact on Members—both generally and in relation to other Members, 
                    <E T="03">i.e.,</E>
                     to assure the fee will not create a financial burden on any participant and will not have an undue impact in particular on smaller Members and competition among Members in general. The Exchange believes that this level of diligence and transparency is called for by the requirements of Section 19(b)(1) under the Act,
                    <SU>6</SU>
                    <FTREF/>

                         In 2019, Commission staff published guidance suggesting the types of information that SROs may use to demonstrate that their fee filings comply with the standards of the Exchange Act (“Fee Guidance”). While MEMX understands that the Fee Guidance does not create new legal obligations on SROs, the Fee Guidance is consistent with MEMX's view about the type and level of transparency that exchanges should meet to demonstrate compliance with their existing obligations when they seek to charge new fees.

                    As detailed below, MEMX calculated its aggregate annual costs for providing physical connectivity to both MEMX Equities and MEMX Options in 2024 at $14,970,454 and its aggregate annual costs for providing application sessions at $7,185,273. In order to cover the aggregate costs of providing connectivity to its Options and Equities Users (both Members and non-Members) going forward and to make a modest profit, as described below, the Exchange is proposing to modify its Fee Schedule, pursuant to MEMX Rules 15.1(a) and (c), to charge a fee to Options Users, as it currently does to Equities Users, of $6,000 per month for each physical connection in the Primary Data Center and of $3,000 per month for each physical connection in the Secondary Data Center. The Exchange also proposes to modify its Fee Schedule, pursuant to MEMX Rules 15.1(a) and (c), to charge a fee to Options Users, as it currently does to Equities Users, of $450 per month for each Order Entry Port and Drop Copy Port in the Exchange's Primary Data Center, as further described below.

                         As proposed, fees for connectivity services would be assessed based on each active connectivity service product at the close of business on the first day of each month. If a product is cancelled by a Member's submission of a written request or via the MEMX User Portal prior to such fee being assessed then the Member will not be obligated to pay the applicable product fee. MEMX will not return pro-rated fees even if a product is not used for an entire month.

                <P>
                    In February 2024, MEMX completed an updated study of its aggregate projected costs to produce market data and connectivity across both its Equities and Options platforms in 2024 (the “Cost Analysis”).
                    <SU>14</SU>
                    <FTREF/>
                     The Cost Analysis required a detailed analysis of MEMX's aggregate baseline costs, including a 
                    <PRTPAGE P="16051"/>
                    determination and allocation of costs for core services provided by the Exchange—transaction execution, market data, membership services and trading permits, regulatory services, physical connectivity, and application sessions (which provide order entry, cancellation and modification functionality, risk functionality, ability to receive drop copies, and other functionality). MEMX separately divided its costs between those costs necessary to deliver each of these core services, including infrastructure, software, human resources (
                    <E T="03">i.e.,</E>
                     personnel), and certain general and administrative expenses (“cost drivers”). Next, MEMX adopted an allocation methodology with various principles to guide how much of a particular cost should be allocated to each core service. For instance, fixed costs that are not driven by client activity (
                    <E T="03">e.g.,</E>
                     message rates), such as data center costs, were allocated more heavily to the provision of physical connectivity (80%), with smaller allocations to logical ports (11%), and the remainder to the provision of transaction execution, regulatory services, and market data services (9%). In contrast, costs that are driven largely by client activity (
                    <E T="03">e.g.,</E>
                     message rates), were not allocated to physical connectivity at all but were allocated primarily to the provision of transaction execution and market data services (80%) with a smaller allocation to application sessions (20%). The allocation methodology was decided through conversations with senior management familiar with each area of the Exchange's operations. After adopting this allocation methodology, the Exchange then applied an estimated allocation of each cost driver to each core service, resulting in the cost allocations described below.

                         The updated Cost Analysis completed in February 2024 is based on the same principles applied to the Cost Analysis completed in September 2023 that was included in the Initial Proposal but contains updated figures now that MEMX Options has been operational for several months.
                    </P>
                </FTNT>
                <P>By allocating segmented costs to each core service, MEMX was able to estimate by core service the potential margin it might earn based on different fee models. The Exchange notes that as a non-listing venue it has four primary sources of revenue that it can potentially use to fund its operations: transaction fees, fees for connectivity services, membership and regulatory fees, and market data fees. Accordingly, the Exchange must cover its expenses from these four primary sources of revenue. The Exchange also notes that as a general matter each of these sources of revenue is based on services that are interdependent. For instance, the Exchange's system for executing transactions is dependent on physical hardware and connectivity; only Members and parties that they sponsor to participate directly on the Exchange may submit orders to the Exchange; many Members (but not all) consume market data from the Exchange in order to trade on the Exchange; and the Exchange consumes market data from external sources in order to comply with regulatory obligations. Accordingly, given this interdependence, the allocation of costs to each service or revenue source required judgment of the Exchange and was weighted based on estimates of the Exchange that the Exchange believes are reasonable, as set forth below.</P>
                <P>Through the Exchange's extensive Cost Analysis, the Exchange analyzed every expense item in the Exchange's general expense ledger to determine whether each such expense relates to the provision of connectivity services, and, if such expense did so relate, what portion (or percentage) of such expense actually supports the provision of connectivity services, and thus bears a relationship that is, “in nature and closeness,” directly related to network connectivity services. In turn, the Exchange allocated certain costs more to physical connectivity and others to application sessions, while certain costs were only allocated to such services at a very low percentage or not at all, using consistent allocation methodologies as described above. Based on this analysis, MEMX estimates that the cost drivers to provide connectivity services in 2024, including both physical connections and application sessions, will result in an aggregate annual cost of $22,155,727, as further detailed below. The Exchange notes that it utilized the same principles to generate the 2021 Cost Analysis, applicable to Equities only, and at that time, the estimated annual aggregate cost to provide connectivity services was $13,724,580. The differences between such estimated costs and the overall analysis are primarily based on: (1) the addition of MEMX Options, (ii) increased, and in some cases decreased, costs projected by the Exchange, (iii) and changes made to reallocate certain costs into categories that more closely align the Exchange's audited financial statements, as further described below.</P>

                     Of the remaining employee time left over, MEMX then calculated an allocation of employee time for employees whose functions include providing and maintaining physical connectivity and performance thereof (primarily the MEMX network infrastructure team, which spends most of their time performing functions necessary to provide physical connectivity) and for which the Exchange allocated 80% of each employee's time. The Exchange also allocated Human Resources costs to provide physical connectivity to a limited subset of personnel with ancillary functions related to establishing and maintaining such connectivity (such as information security and finance personnel), for which the Exchange allocated cost on an employee-by-employee basis (
                    <E T="03">i.e.,</E>

                    <FTREF/>
                     The Exchange notes that it has fewer than 100 employees and each department leader has direct knowledge of the time spent by those spent by each employee with respect to the various tasks necessary to operate the Exchange. The estimates of Human Resources cost were therefore determined by consulting with such department leaders, determining which employees are involved in tasks related to providing physical connectivity, and confirming that the proposed allocations were reasonable based on an understanding of the percentage of their time such employees devote to tasks related to providing physical connectivity. The Exchange notes that senior level executives were only allocated Human Resources costs to the extent the Exchange believed they are involved in overseeing tasks related to providing physical connectivity. The Human Resources cost was calculated using a blended rate of compensation reflecting salary, equity and bonus compensation, benefits, payroll taxes, and 401(k) matching contributions.

                         To reiterate, these allocations are applied to the percentage of employee time left over after the ORF allocation. As such, if 10% of an employee's time was allocated towards options regulation, the percentage of time allocated to physical connectivity in this example would apply to the 90% of the employee's time left over.

                    The Connectivity cost includes external fees paid to connect to other exchanges and third parties. The Exchange notes that its connectivity to external markets is required in order to receive market data to run the Exchange's matching engine and basic operations compliant with existing regulations, primarily Regulation NMS. Approximately 75% of the Exchange's connectivity costs are allocated towards the provision of physical connectivity, which is the same percentage identified in the 2021 Cost Analysis. Of note, the 2021 Cost Analysis allocated approximately $162,000 per month of connectivity costs towards physical connectivity, which is notably higher than the $61,018

The Exchange notes that this is due to a substantial redesign in the Exchange's connectivity plan which achieved the cost savings noted. Additionally, in the 2021 Cost Analysis, certain costs were included in the Connectivity category that have since been moved into the broader Technology category.

                <P>Data Center costs include an allocation of the costs the Exchange incurs to provide physical connectivity in the third-party data centers where it maintains its equipment (such as dedicated space, security services, cooling and power). The Exchange notes that it does not own the Primary Data Center or the Secondary Data Center, but instead, leases space in data centers operated by third parties. The Exchange has allocated a high percentage of the Data Center cost (80%) to physical connectivity because the third-party data centers and the Exchange's physical equipment contained therein is the most direct cost in providing physical access to the Exchange. In other words, for the Exchange to operate in a dedicated space with connectivity of participants to a physical trading platform, the data centers are a very tangible cost, and in turn, if the Exchange did not maintain such a presence then physical connectivity would be of no value to market participants. This slight increase over the allocation of Data Center costs to physical connectivity from 2021 (75%) is due to the Exchange's determination that the Data Center is more directly linked to physical connectivity than any other core service provided by the Exchange.</P>
                <HD SOURCE="HD3">Technology</HD>
                <P>The Technology category includes the Exchange's network infrastructure, other hardware, software, and software licenses used to operate and monitor physical assets necessary to offer physical connectivity to the Exchange. Of note, certain of these costs were included in the Connectivity and a separate Hardware and Software Licenses category in the 2021 Cost Analysis; however, in order to align more closely with the Exchange's audited financial statements these costs were combined into the broader Technology category. The Exchange allocated approximately 25% of its Technology costs to physical connectivity in 2024.</P>
                <HD SOURCE="HD3">Depreciation</HD>
                <P>
                    All physical assets and software, which also includes assets used for testing and monitoring of Exchange infrastructure, were valued at cost, depreciated or leased over periods ranging from three to five years. Thus, the depreciation cost primarily relates to servers necessary to operate the Exchange, some of which are owned by the Exchange and some of which are leased by the Exchange in order to allow efficient periodic technology refreshes. As noted above, the Exchange allocated 39% of all depreciation costs to providing physical connectivity. This is a higher percentage than was allocated to providing physical connectivity in 2021 (18.5%), and this increase is due to a high amount of capital expenditures required to build the Exchange's options platform, none of which began to depreciate until the launch of options in September 2023. The Exchange notes, however, that it did not allocate depreciation costs for any internally developed software to build the Exchange's trading platforms to physical connectivity, as such software does not impact the provision of physical connectivity.

                    Finally, a limited portion of general shared expenses was allocated to physical connectivity as without these general shared costs the Exchange would not be able to operate in the manner that it does and provide physical connectivity. The costs included in general shared expenses include general expenses of the Exchange, including office space and office expenses (
                    <E T="03">e.g.,</E>
                     occupancy and overhead expenses), utilities, recruiting and training, marketing and advertising costs, professional fees for legal, tax and accounting services (including external and internal audit expenses), and telecommunications costs. The Exchange notes that the cost of paying directors to serve on its Board of Directors is also included in the Exchange's general shared expenses, and thus a portion of such overall cost amounting to 7% of the overall cost for directors was allocated to providing physical connectivity.

                <P>
                    As a final part of the Exchange's analysis related to physical connectivity, the Exchange determined the total

                     cost of providing physical connections, (

                    <FTREF/>
                     Thus, the Exchange calculated an average monthly profit of $165,962, resulting in a physical connectivity profit margin of approximately 11.7%.
                    <SU>20</SU>
                    <FTREF/>
                     The Exchange notes that this projected profit margin represents an increase over the projected profit margin noted in the 2021 Cost Analysis related to physical connectivity,
                    <SU>21</SU>
                    <FTREF/>
                     which is in part due to certain cost savings noted above associated with a redesign in the Exchange's external connectivity plan. Nevertheless, the Exchange believes that the projected profit margin is reasonable and well within the range of where a similarly situated company would expect to be after three years of growth, especially upon launching a new trading platform that provides scale. While the Exchange does not anticipate a significant change to physical connectivity during 2024 (
                    <E T="03">i.e.,</E>
                     neither a significant increase nor a significant decrease), it is possible that participants will shift the way that they connect to the Exchange and a reduction occurs or that additional connectivity is established, resulting in an increase.

                         This projection was based off of actuals earned in January and February 2024 and revenue projections for the remainder of the year based off the number of primary and secondary connections maintained as of February 1, 2024, in both Equities and Options. The Exchange notes that its previous method of estimating profit by dividing the cost of providing physical connectivity by the number of physical connections maintained as of the date of proposed pricing is no longer an accurate method. This is due to the fact that such a calculation assumes that the Exchange earns revenue on all physical connections throughout the entire year, which it will not, given that the Exchange will not begin charging for options connections until March 1, 2024, and that the Exchange earns revenue of $6,000 for all physical connections, regardless of whether such connections are found in the primary or secondary data center, which is also not the case.

                    With respect to application sessions, MEMX calculated Human Resources cost by taking an allocation of employee time for employees whose functions include providing application sessions and maintaining performance thereof (including a broader range of employees such as technical operations personnel, market operations personnel, and software engineering personnel) as well as a limited subset of personnel with ancillary functions related to maintaining such connectivity (such as sales, membership, and finance personnel). The estimates of Human Resources cost were again determined by consulting with department leaders, determining which employees are involved in tasks related to providing application sessions and maintaining performance thereof, and confirming that the proposed allocations were reasonable based on an understanding of the percentage of their time such employees devote to tasks related to providing application sessions and maintaining performance thereof. The Exchange notes that senior level executives were only allocated Human Resources costs to the extent the Exchange believed they are involved in overseeing tasks related to providing application sessions and maintaining performance thereof. The Human Resources cost was again calculated

                    using a blended rate of compensation reflecting salary, equity and bonus compensation, benefits, payroll taxes, and 401(k) matching contributions. As shown in the table above, for 2024, the Exchange allocated approximately 11% of its Human Resources costs to providing application sessions, which is higher than the 7.7% it allocated in 2021. This increase is again due to additional hiring needed to support the addition of MEMX Options.

                <P>The Technology category includes the Exchange's network infrastructure, other hardware, software, and software licenses used to monitor the health of the order entry services provided by the Exchange.

                    External Market Data includes fees paid to third parties, including other exchanges, to receive and consume market data from other markets. The Exchange allocated 20% of External Market Data fees to the provision of application sessions as such market data is necessary to offer certain services related to such sessions, such as validating orders on entry against the National Best Bid and National Best Offer (“NBBO”) and checking for other conditions (
                    <E T="03">e.g.,</E>
                     whether a symbol is halted or subject to a short sale circuit breaker). Thus, as market data from other exchanges is consumed at the application session level in order to validate orders before additional processing occurs with respect to such orders, the Exchange believes it is reasonable to allocate a small amount of such costs to application sessions. The increase in allocation of External Market Data costs to the provision of application sessions compared to the 2021 Cost Analysis, in which 7.5% of its External Market Data costs were allocated, is due to a restructuring of the category. Specifically, in 2021, External Market Data only included those costs incurred to receive data from other exchanges, while costs to receive the SIP feeds and other non-exchange data feeds were categorized under Hardware and Software Licenses. These costs are now all categorized under External Market Data.

                    In conducting its Cost Analysis, the Exchange did not allocate any of its expenses in full to any core services (including physical connectivity or application sessions) and did not double-count any expenses. Instead, as described above, the Exchange allocated applicable cost drivers across its core services and used the same Cost Analysis to form the basis of this proposal and the filing it recently submitted proposing the establishment of an ORF.

                     For instance, in calculating the Human Resources expenses to be allocated to physical connections, the Exchange has a team of employees dedicated to network infrastructure and with respect to such employees the Exchange allocated network infrastructure personnel with a high percentage of the time of such personnel (80%) given their focus on functions necessary to provide physical connections. The time of those same personnel were allocated only 4% to application sessions and the remaining 16% was allocated to transactions and market data. Of note, this allocation applied only to the network infrastructure employee's time that was left over after allocating for options regulation support. The Exchange did not allocate any other Human Resources expense for providing physical connections to any other employee group outside of a smaller allocation 
                    <PRTPAGE P="16055"/>
                    (30%) of the employee time associated with certain specified personnel who work closely with and support network infrastructure personnel. In contrast, the Exchange allocated much smaller percentages of employee time (15% or less) across a wider range of personnel groups in order to allocate Human Resources costs to providing application sessions. This is because a much wider range of personnel are involved in functions necessary to offer, monitor and maintain application sessions but the tasks necessary to do so are not a primary or full-time function.

                <P>In total, the Exchange allocated 18% of its Human Resources costs to providing physical connections and 11% of its Human Resources costs to providing application sessions, for a total allocation of 29% of its Human Resources expense to provide connectivity services. In turn, the Exchange allocated the remaining 71% of its Human Resources expense to Regulatory Services (21%), membership (2%) and transactions and market data (48%). Thus, again, the Exchange's allocations of cost across core services were based on real costs of operating the Exchange and were not double-counted across the core services or their associated revenue streams.</P>
                <P>As another example, the Exchange allocated depreciation expense to all core services, including physical connections and application sessions, but in different amounts. The Exchange believes it is reasonable to allocate the identified portion of such expense because such expense includes the actual cost of the computer equipment, such as dedicated servers, computers, laptops, monitors, information security appliances and storage, and network switching infrastructure equipment, including switches and taps that were purchased to operate and support the network. Without this equipment, the Exchange would not be able to operate the network and provide connectivity services to its Members and non-Members and their customers. However, the Exchange did not allocate all of the depreciation and amortization expense toward the cost of providing connectivity services, but instead allocated approximately 53% of the Exchange's overall depreciation and amortization expense to connectivity services (39% attributed to physical connections and 14% to application sessions). The Exchange allocated the remaining depreciation and amortization expense (approximately 47%) toward regulatory services (approximately 6%), and to providing transaction services and market data (approximately 41%).  </P>
                <P>
                    Looking at the Exchange's operations holistically, the estimated total monthly costs to the Exchange for offering core services in 2024 is $5,299,754, compared to the $3,954,537 noted in the 2021 Cost Analysis. Based on its projections, the Exchange expects to collect approximately $2,076,238 on a monthly basis for connectivity services. Incorporating this amount into the Exchange's overall projected revenue, including projections related to the ORF, the Exchange anticipates monthly revenue of approximately $6,080,631 from all sources (
                    <E T="03">i.e.,</E>
                     connectivity fees and membership fees, transaction fees, ORF, and revenue from market data, both through the fees adopted in April 2022

                    <FTREF/>
                     and through the revenue received from the SIPs). As such, applying the Exchange's holistic Cost Analysis to a holistic view of anticipated revenues, the Exchange would earn approximately 13% margin on its operations as a whole. The Exchange believes that this amount is reasonable.

                <P>The Exchange notes that its revenue estimates are based on projections across all potential revenue streams and will only be realized to the extent such revenue streams actually produce the revenue estimated. As a new entrant to the hyper-competitive exchange environment, and an exchange focused on driving competition, the Exchange does not yet know whether such expectations will be realized. For instance, in order to generate the revenue expected from connectivity, the Exchange will have to be successful in retaining existing options clients that wish to maintain physical connectivity and/or application sessions or in obtaining new clients that will purchase such services. Similarly, the Exchange will have to be successful in retaining a positive net capture on transaction fees in order to realize the anticipated revenue from transaction pricing.</P>

                    The Exchange notes that the Cost Analysis was based on the Exchange's current operations and projections for the remainder of 2024. As such, the Exchange believes that its costs will remain relatively similar in future years (as demonstrated by the comparison of the 2021 Cost Analysis to the 2024 Cost Analysis). It is possible however that such costs will either decrease or increase. To the extent the Exchange sees growth in use of connectivity services it will receive additional revenue to offset future cost increases. However, if use of connectivity services is static or decreases, the Exchange might not realize the revenue that it anticipates or needs in order to cover applicable costs. Accordingly, the Exchange is committing to conduct a one-year review after implementation of these fees. The Exchange expects that it may propose to adjust fees at that time, to increase fees in the event that revenues fail to cover costs and a reasonable mark-up of such costs. Similarly, the Exchange would propose to decrease fees in the event that revenue materially exceeds our current projections. In addition, the Exchange will periodically conduct a review to inform its decision making on whether a fee change is appropriate (
                    <E T="03">e.g.,</E>
                     to monitor for costs increasing/decreasing or subscribers increasing/decreasing in ways that suggest the then-current fees are becoming dislocated from the prior cost-based analysis) and would propose to increase fees in the event that revenues fail to cover its costs and a reasonable mark-up, or decrease fees in the event that revenue or the mark-up materially exceeds our current projections. In the event that the Exchange determines to propose a fee change, the results of a timely review, including an updated cost estimate, will be included in the rule filing proposing the fee change. More generally, the Exchange believes that it is appropriate for an exchange to refresh and update information about its relevant costs and revenues in seeking any future changes to fees, and the Exchange commits to do so.

Extranet physical connections may provide access to one or multiple Members on a single connection. Users of MEMX physical connectivity services (both Members and non-Members

Upon receipt of the completed instructions, MEMX establishes the physical connections requested by the User. The number of physical connections assigned to each User (for both equities and options) as of October 1, 2023, ranges from one (1) 
                    <PRTPAGE P="16056"/>
                    to 46, depending on the scope and scale of the Member's trading activity on the Exchange as determined by the Member, including the Member's determination of the need for redundant connectivity. Separate physical connections are not required to access the Exchange's Options and Equities platforms, as such, a User could use a single connection to access both platforms. The Exchange notes that 50% of its Members do not maintain a physical connection directly with the Exchange in the Primary Data Center (though many such Members have connectivity through a third-party provider) and 21 members, or 27.6% have either one or two physical ports to connect to the Exchange in the Primary Data Center.

                <P>As described above, the Exchange has previously justified its pricing with respect to MEMX Equities and believes the most fair approach, absent a significant differentiation between application costs to Equities and Options, is to apply the same pricing to all participants of either platform. As such, in order to cover the aggregate costs of providing physical connectivity to Options and Equities Users and make a modest profit, as described below, the Exchange is proposing to charge a fee of $6,000 per month for each physical connection in the Primary Data Center and a fee of $3,000 per month for each physical connection in the Secondary Data Center for connections to its Options platform, as it currently charges for connections to its Equities platform. There is no requirement that any Member maintain a specific number of physical connections and a Member may choose to maintain as many or as few of such connections as each Member deems appropriate. Further, as noted above, existing Equities Members may choose to use their existing physical connection(s) to access the Exchange's Options platform.</P>
                <P>
                    The Exchange notes, however, that pursuant to Rule 2.4 (Mandatory Participation in Testing of Backup Systems), the Exchange does require a small number of Members to connect and participate in functional and performance testing as announced by the Exchange, which occurs at least once every 12 months. Specifically, Members that have been determined by the Exchange to contribute a meaningful percentage of the Exchange's overall volume must participate in mandatory testing of the Exchange's backup systems (
                    <E T="03">i.e.,</E>
                     such Members must connect to the Secondary Data Center). The Exchange notes that designated Members are still able to use third-party providers of connectivity to access the Exchange at its Secondary Data Center, and that for its Equities platform, one of eight such designated Members does use a third-party provider instead of connecting directly to the Secondary Data Center through connectivity provided by the Exchange. Nonetheless, because some Members are required to connect to the Secondary Data Center pursuant to Rule 2.4 and to encourage Exchange Members to connect to the Secondary Data Center generally, the Exchange has proposed to charge one-half of the fee for a physical connection in the Primary Data Center for its Options platform, as it currently charges for Equities. The Exchange notes that its costs related to operating the Secondary Data Center were not separately calculated for purposes of this proposal, but instead, all costs related to providing physical connections were considered in the aggregate. The Exchange believes this is appropriate because had the Exchange calculated such costs separately and then determined the fee per physical connection that would be necessary for the Exchange to cover its costs for operating the Secondary Data Center, the costs would likely be much higher than those proposed for connectivity at the Primary Data Center because Members maintain significantly fewer connections at the Secondary Data Center. The Exchange believes that charging a higher fee for physical connections at the Secondary Data Center would be inconsistent with its objective of encouraging Members to connect at such data center and is inconsistent with the fees charged by other exchanges, which also provide connectivity for disaster recovery purposes at a discounted rate.

                <P>The proposed fee will not apply differently based upon the size or type of the market participant, but rather based upon the number of physical connections a User requests, based upon factors deemed relevant by each User (either a Member, service bureau or extranet). The Exchange believes these factors include the costs to maintain connectivity, business model and choices Members make in how to participate on the Exchange, as further described below.</P>
                <P>The proposed fee of $6,000 per month for physical connections at the Primary Data Center is designed to permit the Exchange to cover the costs allocated to providing connectivity services with a modest profit margin (approximately 11.7%), which would also help fund future expenditures (increased costs, improvements, etc.). The Exchange believes it is appropriate to charge fees that represent a reasonable markup over cost given the other factors discussed above and the need for the Exchange to maintain a highly performant and stable platform to allow Members to transact with determinism.</P>
                <P>As noted above, the Exchange proposes a discounted rate of $3,000 per month for physical connections at its Secondary Data Center. The Exchange has proposed this discounted rate for Secondary Data Center connectivity in order to encourage Members to establish and maintain such connections. Also, as noted above, a small number of Members are required pursuant to Rule 2.4 to connect and participate in testing of the Exchange's backup systems, and the Exchange believes it is appropriate to provide a discounted rate for physical connections at the Secondary Data Center given this requirement. The Exchange notes that this rate is well below the cost of providing such services and the Exchange will operate its network and systems at the Secondary Data Center without recouping the full amount of such cost through connectivity services.</P>

                    <PRTPAGE P="16057"/>
                    sessions requested by the User. The number of sessions assigned to each User as of February 1, 2024, ranges from one (1) to more than 300 depending on the scope and scale of the Member's trading activity on the Exchange (either through a direct connection or through a service bureau) as determined by the Member. For example, by using multiple sessions, Members can segregate order flow from different internal desks, business lines, or customers. The Exchange does not impose any minimum or maximum requirements for how many application sessions a Member or service bureau can maintain, and it is not proposing to impose any minimum or maximum session requirements for its Members or their service bureaus. The same application session cannot be used to access both MEMX Equities and MEMX Options, as such, Users will need to purchase separate application sessions for MEMX Options, which differs from physical connections.

                <P>As described above, in order to cover the aggregate costs of providing application sessions to Options Users and to make a modest profit, as described below, the Exchange is proposing to charge a fee of $450 per month for each Order Entry Port and Drop Copy Port in the Primary Data Center for Options application sessions, which is the same fee it currently charges for Equities application sessions. The Exchange notes that it does not propose to charge for: (1) Order Entry Ports or Drop Copy Ports in the Secondary Data Center, or (2) any Test Facility Ports or MEMOIR Gap Fill Ports, again, which it does not charge for Equities Users. The Exchange has proposed to continue to provide Order Entry Ports and Drop Copy Ports in the Secondary Data Center for Options free of charge in order to encourage Members to connect to the Exchange's backup trading systems. Similarly, because the Exchange wishes to encourage Members to conduct appropriate testing of their use of the Exchange, the Exchange has not proposed to charge for Test Facility Ports. With respect to MEMOIR Gap Fill ports, such ports are exclusively used in order to receive information when a market data recipient has temporarily lost its view of MEMX market data. The Exchange has not proposed charging for such ports because the costs of providing and maintaining such ports is more directly related to producing market data.</P>
                <P>The proposed fee of $450 per month for each Order Entry Port and Drop Copy Port in the Primary Data Center is designed to permit the Exchange to cover the costs allocated to providing application sessions with a modest profit margin (approximately 9.7%), which would also help fund future expenditures (increased costs, improvements, etc.).</P>
                <P>
                    The proposed fee is also designed to encourage Users to be efficient with their application session usage, thereby resulting in a corresponding increase in the efficiency that the Exchange would be able to realize in managing its aggregate costs for providing connectivity services. There is no requirement that any Member maintain a specific number of application sessions and a Member may choose to maintain as many or as few of such ports as each Member deems appropriate. The Exchange has designed its platform such that Order Entry Ports can handle a significant amount of message traffic (
                    <E T="03">i.e.,</E>
                     over 50,000 orders per second), and has no application flow control or order throttling. In contrast, other exchanges maintain certain thresholds that limit the amount of message traffic that a single logical port can handle.

                     As such, while several Members maintain a relatively high number of ports because that is consistent with their usage on other exchanges and is preferable for their own reasons, the Exchange believes that it has designed a system capable of allowing such Members to significantly reduce the number of application sessions maintained.

                         The Exchange understands that some Members (or service bureaus) may also request more Order Entry Ports to enable the ability to send a greater number of simultaneous order messages to the Exchange by spreading orders over more Order Entry Ports, thereby increasing throughput (
                        <E T="03">i.e.,</E>
                         the potential for more orders to be processed in the same amount of time). The degree to which this usage of Order Entry Ports provides any throughput advantage is based on how a particular Member sends order messages to MEMX, however the Exchange notes that its architecture reduces the impact or necessity of such a strategy. All Order Entry Ports on MEMX provide the same throughput, and as noted above, the throughput is likely adequate even for a Member sending a significant amount of volume at a fast pace, and is not artificially throttled or limited in any way by the Exchange.

                    As discussed above, the proposed fees for connectivity services do not by design apply differently to different types or sizes of Members. As discussed in more detail in the Statutory Basis section, the Exchange believes that the likelihood of higher fees for certain Members subscribing to connectivity services usage than others is not unfairly discriminatory because it is based on objective differences in usage of connectivity services among different Members. The Exchange's incremental aggregate costs for all connectivity services are disproportionately related to Members with higher message traffic and/or Members with more complicated connections established with the Exchange, as such Members: (1) consume the most bandwidth and resources of the network; (2) transact the vast majority of the volume on the Exchange; and (3) require the high-touch network support services provided by the Exchange and its staff, including network monitoring, reporting and support services, resulting in a much higher cost to the Exchange to provide such connectivity services. For these reasons, MEMX believes it is not unfairly discriminatory for the Members with higher message traffic and/or Members with more complicated connections to pay a higher share of the total connectivity services fees. While Members with a business model that results in higher relative inbound message activity or more complicated connections are projected to pay higher fees, the level of such fees is based solely on the number of physical connections and/or application sessions deemed necessary by the Member and not on the Member's business model or type of Member. The Exchange notes that the correlation between message traffic and usage of connectivity services is not completely aligned because Members individually determine how many physical connections and application sessions to request, and Members may make different decisions on the appropriate ways based on facts unique to their individual businesses. Based on the Exchange's architecture, as described above, the Exchange believes that a Member even with high message traffic would be able to conduct business on the Exchange with a 
                    <PRTPAGE P="16058"/>
                    relatively small connectivity services footprint.
                </P>
                <P>
                    Finally, the fees for connectivity services will help to encourage connectivity services usage in a way that aligns with the Exchange's regulatory obligations. As a national securities exchange, the Exchange is subject to Regulation Systems Compliance and Integrity (“Reg SCI”).
                    <SU>33</SU>
                    <FTREF/>
                     Reg SCI Rule 1001(a) requires that the Exchange establish, maintain, and enforce written policies and procedures reasonably designed to ensure (among other things) that its Reg SCI systems have levels of capacity adequate to maintain the Exchange's operational capability and promote the maintenance of fair and orderly markets.
                    <SU>34</SU>
                    <FTREF/>
                     By encouraging Users to be efficient with their usage of connectivity services, the proposed fee will support the Exchange's Reg SCI obligations in this regard by ensuring that unused application sessions are available to be allocated based on individual User needs and as the Exchange's overall order and trade volumes increase. Additionally, because the Exchange will charge a lower rate for a physical connection to the Secondary Data Center and will not charge any fees for application sessions at the Secondary Data Center or its Test Facility, the proposed fee structure will further support the Exchange's Reg SCI compliance by reducing the potential impact of a disruption should the Exchange be required to switch to its Disaster Recovery Facility and encouraging Members to engage in any necessary system testing with low or no cost imposed by the Exchange.

However, the Exchange notes that a third-party service provider providing connectivity to the Exchange likely would charge a fee for providing such connectivity; such fees are not set by or shared in by the Exchange.

                <HD SOURCE="HD3">(ii) Organizational Fee Schedule Changes</HD>
                <P>
                    The Exchange is proposing to more clearly separate Connectivity Fees from the Exchange's current fee schedule. Currently, the Exchange has separate transaction fee schedules for Equities and Options, and the current Connectivity Fees appear solely on the Equities fee schedule. The Exchange proposes to remove the Connectivity Fees section from the Equities fee schedule, and add hyperlinks at the bottom of the Equities and Options fee schedules that direct the User to a single Connectivity fee schedule. The Exchange believes this format is appropriate given that the same Connectivity Fees apply to both Equities and Options Users, and separating out the fee schedule for Connectivity Fees will reduce potential confusion (
                    <E T="03">e.g.,</E>
                     as to which fees a Member that participates on both MEMX Equities and MEMX Options must pay on a monthly basis to maintain connectivity to the Exchange).
                </P>
                <P>
                    The Exchange also proposes to add three additional bullet points to the new Connectivity Fee Schedule related to MEMX Options. The first will notify Members that a physical connection can be used to access MEMX Equities and/or MEMX Options. The second will clarify that an application session can only be used to access one MEMX platform, 
                    <E T="03">i.e.,</E>
                     MEMX Equities or MEMX Options. The third will note that Connectivity and application session fees solely related to participation on MEMX Options are waived until March 1, 2024.

                <P>The Exchange believes that the proposed fees for connectivity services to MEMX Options are reasonable, equitable and not unfairly discriminatory because, as described above, the proposed pricing for connectivity services is directly related to the relative costs to the Exchange to provide those respective services and does not impose a barrier to entry to smaller participants.  </P>
                <P>
                    The Exchange recognizes that there are various business models and varying sizes of market participants conducting business on the Exchange. The Exchange's incremental aggregate costs for all connectivity services are disproportionately related to Members with higher message traffic and/or Members with more complicated connections established with the Exchange, as such Members: (1) consume the most bandwidth and resources of the network; (2) transact the vast majority of the volume on the Exchange; and (3) require the high-touch network support services provided by the Exchange and its staff, including network monitoring, reporting and support services, resulting in a much higher cost to the Exchange to provide such connectivity services. Accordingly, the Exchange believes the allocation of the proposed fees that increase based on the number of physical connections or application sessions is reasonable based on the resources consumed by the respective type of market participant (
                    <E T="03">i.e.,</E>
                     lowest resource consuming Members will pay the least, and highest resource consuming Members will pay the most), particularly since higher resource consumption translates directly to higher costs to the Exchange.
                </P>
                <P>With regard to reasonableness, the Exchange understands that when appropriate given the context of a proposal the Commission has taken a market-based approach to examine whether the SRO making the proposal was subject to significant competitive forces in setting the terms of the proposal. In looking at this question, the Commission considers whether the SRO has demonstrated in its filing that: (i) there are reasonable substitutes for the product or service; (ii) “platform” competition constrains the ability to set the fee; and/or (iii) revenue and cost analysis shows the fee would not result in the SRO taking supra-competitive profits. If the SRO demonstrates that the fee is subject to significant competitive forces, the Commission will next consider whether there is any substantial countervailing basis to suggest the fee's terms fail to meet one or more standards under the Exchange Act. If the filing fails to demonstrate that the fee is constrained by competitive forces, the SRO must provide a substantial basis, other than competition, to show that it is consistent with the Exchange Act, which may include production of relevant revenue and cost data pertaining to the product or service.</P>
                <P>
                    MEMX believes the proposed fees for connectivity services are fair and reasonable as a form of cost recovery for the Exchange's aggregate costs of offering connectivity services to Members and non-Members. The proposed fees are expected to generate monthly revenue of $2,076,238 providing cost recovery to the Exchange for the aggregate costs of offering 
                    <PRTPAGE P="16059"/>
                    connectivity services, based on a methodology that narrowly limits the cost drivers that are allocated cost to those closely and directly related to the particular service. In addition, this revenue will allow the Exchange to continue to offer, to enhance, and to continually refresh its infrastructure as necessary to offer a state-of-the-art trading platform. The Exchange believes that, consistent with the Act, it is appropriate to charge fees that represent a reasonable markup over cost given the other factors discussed above. The Exchange also believes the proposed fee is a reasonable means of encouraging Users to be efficient in the connectivity services they reserve for use, with the benefits to overall system efficiency to the extent Members and non-Members consolidate their usage of connectivity services or discontinue subscriptions to unused physical connectivity.
                </P>
                <P>The Exchange further believes that the proposed fees, as they pertain to purchasers of each type of connectivity alternative, constitute an equitable allocation of reasonable fees charged to the Exchange's Members and non-Members and are allocated fairly amongst the types of market participants using the facilities of the Exchange.</P>
                <P>As described above, the Exchange believes the proposed fees are equitably allocated because the Exchange's incremental aggregate costs for all connectivity services are disproportionately related to Members with higher message traffic and/or Members with more complicated connections established with the Exchange, as such Members: (1) consume the most bandwidth and resources of the network; (2) transact the vast majority of the volume on the Exchange; and (3) require the high-touch network support services provided by the Exchange and its staff, including network monitoring, reporting and support services, resulting in a much higher cost to the Exchange to provide such connectivity services.</P>
                <P>
                    Commission staff previously noted that the generation of supra-competitive profits is one of several potential factors in considering whether an exchange's proposed fees are consistent with the Act.
                    <SU>37</SU>
                    <FTREF/>
                     As described in the Fee Guidance, the term “supra-competitive profits” refers to profits that exceed the profits that can be obtained in a competitive market. The proposed fee structure would not result in excessive pricing or supra-competitive profits for the Exchange. The proposed fee structure is merely designed to permit the Exchange to cover the costs allocated to providing connectivity services with a modest margin (approximately 11.7% for physical connectivity and 9.7% for application sessions), which would also help fund future expenditures (increased costs, improvements, etc.). While the Fee Guidance did not establish a guideline as to what constitutes supra-competitive pricing through analyzing margin (nor does the Exchange believe it should have), the Exchange does not believe that it would be reasonable to consider the aforementioned margins to constitute supra-competitive pricing. As noted above, the increase in margin for connectivity services is primarily driven by certain cost savings that the Exchange has been able to achieve as compared to the 2021 Cost Analysis, and the Exchange does not believe it should be penalized, and instead should be rewarded for identifying and realizing such savings. Of course, should the Exchange find opportunities to dramatically reduce costs or increase revenues such that it believes the cost it is charging for physical connections or applications sessions is inconsistent with the cost of providing such connectivity or resulting in unreasonable margin, the Exchange will seek to lower its fees in order to pass savings on to its constituents. Thus, the Exchange believes that its proposed pricing for Connectivity Fees is fair, reasonable, and equitable. Further, the Exchange notes that certain of its competitors have connectivity fees that were approved without the presentation of a cost-based analysis, but it is reasonable to assume that certain of those competitors with significantly higher fees also operate with significantly higher profit margins. Accordingly, the Exchange believes that its proposal is consistent with Section 6(b)(4) 
                    <SU>38</SU>
                    <FTREF/>

                    The proposed fees for Options connectivity services will allow the Exchange to cover certain costs incurred by the Exchange associated with providing and maintaining necessary hardware and other network infrastructure as well as network monitoring and support services; without such hardware, infrastructure, monitoring and support the Exchange would be unable to provide the connectivity services. The Exchange routinely works to improve the performance of the network's hardware and software. The costs associated with maintaining and enhancing a state-of-the-art exchange network is a significant expense for the Exchange, and thus the Exchange believes that it is reasonable and appropriate to help offset those costs by adopting fees for connectivity services. As detailed above, the Exchange has four primary sources of revenue that it can potentially use to fund its operations: transaction fees, fees for connectivity services, membership and regulatory fees, and market data fees. Accordingly, the Exchange must cover its expenses from these four primary sources of revenue. The Exchange's Cost Analysis estimates the monthly costs to provide connectivity services at $1,846,310.58. Based on current connectivity services usage, the Exchange would generate monthly revenues of approximately $2,076,238. This represents a modest profit when compared to the cost of providing connectivity services and that profit represents a modest increase over the profit estimated in the 2021 Cost Analysis (a reasonable goal for a newly formed business, 
                    <E T="03">i.e.,</E>

                    <FTREF/>
                     Even if the Exchange earns that amount or incrementally more, the Exchange believes the proposed fees for connectivity services are fair and reasonable because they will not result in excessive pricing or supra-competitive profit, when comparing the total expense of MEMX associated with providing connectivity services versus the total projected revenue of the Exchange associated with network connectivity services.

                         Specifically, in the 2021 Cost Analysis, the Exchange estimated the total costs to provide connectivity services at $1,143,715 and estimated monthly revenues of $1,233,750.
                    </P>
                </FTNT>
                <P>As noted above, when incorporating the projected revenue from connectivity services into the Exchange's overall projected revenue, including projections related to recently adopted market data fees, the Exchange anticipates monthly revenue of $6,080,631 from all sources. As such, applying the Exchange's holistic Cost Analysis to a holistic view of anticipated revenues, the Exchange would earn approximately 13% margin on its operations as a whole. The Exchange believes that this amount is reasonable and is again evidence that the Exchange will not earn a supra-competitive profit.  </P>
                <P>
                    The Exchange notes that other exchanges offer similar connectivity options to market participants and that the Exchange's fees are a discount as compared to the majority of such fees.

                         This range is based on a review of the fees charged for 10-40Gb connections at each of these exchanges and relates solely to the physical port fee or connection charge, excluding co-location fees and other fees assessed by these exchanges. The Exchange notes that it does not offer physical connections with lower bandwidth than 10Gb and that Members and non-Members with lower bandwidth requirements typically access the Exchange through third-party extranets or service bureaus.

                         As noted above, all physical connections offered by MEMX are at least 10Gb capable and physical connections provided with larger bandwidth capabilities will be provided at the same rate as such connections. In contrast to other exchanges, MEMX has not proposed different types of physical connections with higher pricing for those with greater capacity.

                     for the reasons discussed above in that it provides for the equitable allocation of reasonable dues, fees and other charges among its Members and other persons using its facilities, does not permit unfair discrimination between customers, issuers, brokers, or dealers, and is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system and in general to protect investors and the public interest, particularly as the proposal neither targets nor will it have a disparate impact on any particular category of market participant.

                <P>The Exchange believes that the proposed reorganization of its fee schedule to establish a separate fee schedule for Connectivity Fees is reasonable and equitable because it is a non-substantive change and does not involve changing any existing fees or rebates that apply to trading activity on MEMX Equities. Further, the changes are designed to make the fee schedule easier to read and for Members to validate the bills they receive from the Exchange. The Exchange also believes this reorganization is non-discriminatory because it applies uniformly to all Members. The Exchange believes the proposed fee schedule will be clearer and less confusing for Members of the Exchange and will eliminate potential Member confusion, thereby removing impediments to and perfecting the mechanism of a free and open market and a national market, and in general, protecting investors and the public interest.</P>

                <P>
                    The Exchange does not believe that the proposed rule change to apply the same Connectivity Fees to Options Users as it does to Equities Users would place certain market participants at the Exchange at a relative disadvantage compared to other market participants because the proposed connectivity pricing is associated with relative usage of the Exchange by each market participant and does not impose a barrier to entry to smaller participants. As noted above, the Exchange has previously justified its pricing with respect to MEMX Equities and believes the most fair approach, absent a significant differentiation between application costs to Equities and Options, is to apply the same pricing to all participants of either platform. The Exchange believes its proposed pricing is reasonable and lower than what other options exchanges charge and, when coupled with the availability of third-party providers that also offer connectivity solutions, that participation on the Exchange is 
                    <PRTPAGE P="16061"/>
                    affordable for all market participants, including smaller trading firms. Therefore, the fees may stimulate intramarket competition by attracting additional firms to become Members of MEMX Options. As described above, the connectivity services purchased by market participants typically increase based on their additional message traffic and/or the complexity of their operations. The market participants that utilize more connectivity services typically utilize the most bandwidth, and those are the participants that consume the most resources from the network. Accordingly, the proposed fees for connectivity services do not favor certain categories of market participants in a manner that would impose a burden on competition; rather, the allocation of the proposed Connectivity Fees reflects the network resources consumed by the various size of market participants and the costs to the Exchange of providing such connectivity services.
                </P>
                <P>As it relates to the reorganization of the fee schedule, as discussed above, the Exchange does not believe that the proposed change would impose any burden on competition because such change serves to create an easier to read fee schedule to avoid any Member confusion.  </P>
                <HD SOURCE="HD3">Intermarket Competition</HD>
                <P>
                    The Exchange does not believe the proposed fees for Options Connectivity place an undue burden on competition on other SROs that is not necessary or appropriate. Additionally, other exchanges have similar connectivity alternatives for their participants, but with higher rates to connect.
                    <SU>49</SU>
                    <FTREF/>
                     The Exchange is also unaware of any assertion that the proposed fees for connectivity services would somehow unduly impair its competition with other exchanges. As a new entrant in an already highly competitive environment for equity options trading, MEMX does not have the market power necessary to set prices for services that are unreasonable or unfairly discriminatory in violation of the Exchange Act. In sum, MEMX's proposed Connectivity Fees for Options Members are comparable to and generally lower than fees charged by other options exchanges for the same or similar services.

                <P>
                    In 2020, in order to assist ETP Holders' efforts to manage their risk, the Exchange amended its rules to add Rule 7.19E (Pre-Trade Risk Controls),
                    <SU>3</SU>
                    <FTREF/>
                     which established a set of optional pre-trade risk controls by which Entering Firms and their designated Clearing Firms 
                    <SU>4</SU>
                    <FTREF/>
                     could set credit limits and other pre-trade risk controls for an Entering Firm's trading on the Exchange and authorize the Exchange to take action if those credit limits or other pre-trade risk controls are exceeded. These pre-trade risk controls include a Gross Credit Risk Limit, which is defined in Rule 7.19E(b)(1) as “a pre-established maximum daily dollar amount for purchases and sales across all symbols, where both buy and sell orders are counted as positive values.” The current version of Rule 7.19E(b)(1) specifies that both open and executed orders are considered: “[f]or purposes of calculating the Gross Credit Risk Limit, unexecuted orders in the Exchange Book, orders routed on arrival pursuant to Rule 7.37E(a)(1), and executed orders are included.”

                <P>
                    The Exchange has recently received several requests from market participants to create two additional 
                    <PRTPAGE P="16063"/>
                    Gross Credit Risk Limit risk controls: one that includes only open orders and another that includes only executed orders. Market participants have explained that Entering Firms and Clearing Firms would benefit from having more granular gross credit risk controls available, which would allow them to set limits and breach actions based solely on open orders or executed orders, in addition to the Exchange's existing Gross Credit Risk Limit that includes both open and executed orders.
                </P>
                <P>
                    The Exchange notes that the MIAX Pearl equities exchange (“MIAX Pearl”) currently offers risk controls substantially similar to those proposed here. Specifically, MIAX Pearl offers its “Equity Members” and their “Clearing Members” the option to use a “Gross Notional Trade Value” risk check, which includes only executed orders, and a “Gross Notional Open Value” risk check, which includes only unexecuted orders, in addition to a “Gross Notional Open and Trade Value” risk check, for which both executed and unexecuted orders are included.

                    <FTREF/>
                     As such, market participants are already familiar with these various gross credit risk checks, such that the ones proposed by the Exchange in this filing are not novel.

                </FTNT>
                <P>In light of these requests, the Exchange proposes to amend Rule 7.19E(b)(1) to rename the existing Gross Credit Risk Limit as “Gross Credit Risk Limit—Open + Executed,” and to add two additional risk limits: “Gross Credit Risk Limit—Open Only” and “Gross Credit Risk Limit—Executed Only.”</P>
                <P>Specifically, the Exchange proposes to amend and reorganize Rule 7.19E(b)(1) as follows. First, the Exchange would amend the language in the first sentence of the rule to refer to plural Gross Credit Risk Limits, instead of just one. At the end of the first sentence, the Exchange would add that “[a]vailable Gross Credit Risk Limits include” the three types described in new sub-sections (A), (B), and (C).</P>
                <P>Proposed sub-section (A) would define the “Gross Credit Risk Limit—Open + Executed” risk check to include unexecuted orders in the Exchange Book, orders routed on arrival pursuant to Rule 7.37E(a)(1), and executed orders (just as the current Gross Credit Risk Limit does).</P>
                <P>Proposed sub-section (B) would define the “Gross Credit Risk Limit—Open Only” risk check to include only unexecuted orders in the Exchange Book and orders routed on arrival pursuant to Rule 7.37E(a)(1).</P>
                <P>Proposed sub-section (C) would define the “Gross Credit Risk Limit—Executed Only” risk check to include executed orders only.</P>
                <P>In addition, the Exchange proposes to make a conforming change to section (c)(1)(B) of the rule, to make plural the current singular reference to “Gross Credit Risk Limit.”</P>
                <P>As with the Exchange's existing risk controls, use of the pre-trade risk controls proposed herein would be optional. The Exchange proposes no other changes to Rule 7.19E or its Commentary.</P>

                <P>
                    The proposed Pre-Trade Risk Controls described here are meant to supplement, and not replace, the ETP Holders' own internal systems, monitoring, and procedures related to risk management. The Exchange does not guarantee that these controls will be sufficiently comprehensive to meet all of an ETP Holder's needs, the controls are not designed to be the sole means of risk management, and using these controls will not necessarily meet an ETP Holder's obligations required by Exchange or federal rules (including, without limitation, the Rule 15c3-5 under the Act

                     (“Rule 15c3-5”)). Use of the Exchange's Pre-Trade Risk Controls will not automatically constitute compliance with Exchange or federal rules and responsibility for compliance with all Exchange and SEC rules remains with the ETP Holder.

                <P>The Exchange anticipates implementing the proposed change in the first quarter of 2024 and, in any event, will implement the proposed rule change no later than the end of June 2024. The Exchange will announce the timing of such changes by Trader Update.</P>

                    The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act,

                    <FTREF/>

                    <FTREF/>
                     in particular, because it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest, and because it is not designed to permit unfair discrimination between customers, issuers, brokers, or dealers.

                <P>
                    Specifically, the Exchange believes that the proposed rule change will remove impediments to and perfect the mechanism of a free and open market and a national market system because the proposed additional Pre-Trade Risk Controls would provide Entering Firms and Clearing Firms with enhanced abilities to manage their risk with respect to orders on the Exchange. The proposed additional Pre-Trade Risk Controls are not novel; they are based on existing risk settings already in place on MIAX Pearl and market participants are already familiar with the types of protections that the proposed risk controls afford.
                    <SU>10</SU>
                    <FTREF/>
                     As such, the Exchange believes that the proposed additional Pre-Trade Risk Controls would provide a means to address potentially market-impacting events, helping to ensure the proper functioning of the market.

                </FTNT>
                <P>In addition, the Exchange believes that the proposed rule change will protect investors and the public interest because the proposed additional Pre-Trade Risk Controls are a form of impact mitigation that will aid Entering Firms and Clearing Firms in minimizing their risk exposure and reduce the potential for disruptive, market-wide events. The Exchange understands that ETP Holders implement a number of different risk-based controls, including those required by Rule 15c3-5. The controls proposed here will serve as an additional tool for Entering Firms and Clearing Firms to assist them in identifying any risk exposure. The Exchange believes the proposed additional Pre-Trade Risk Controls will assist Entering Firms and Clearing Firms in managing their financial exposure which, in turn, could enhance the integrity of trading on the securities markets and help to assure the stability of the financial system.</P>
                <P>
                    Finally, the Exchange believes that the proposed rule change does not unfairly discriminate among the Exchange's ETP Holders because use of the proposed additional Pre-Trade Risk Controls is optional and is not a prerequisite for participation on the Exchange.

                <P>The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. In fact, the Exchange believes that the proposal will have a positive effect on competition because, by providing Entering Firms and Clearing Firms additional means to monitor and control risk, the proposed rule will increase confidence in the proper functioning of the markets. The Exchange believes the proposed additional Pre-Trade Risk Controls will assist Entering Firms and Clearing Firms in managing their financial exposure which, in turn, could enhance the integrity of trading on the securities markets and help to assure the stability of the financial system. As a result, the level of competition should increase as public confidence in the markets is solidified.</P>

                    Currently, the Exchange offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     The purpose of the proposed rule change is to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW, in addition to those reservations currently offered under the program.

                    <FTREF/>
                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

                         Due to heightened demand for power and cabinets, NYSE established certain procedures related to PNU cabinet conversion and restrictions on new PNU cabinet offerings. NYSE adopted a policy that, if unallocated cabinet inventory is at or below 40 cabinets, new PNU cabinets are not offered. However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>

                <P>
                    The Exchange believes that its proposal is consistent with section 6(b) of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).

                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

                <P>The Exchange does not believe that the proposed rule change will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act.</P>
                <P>Nothing in the proposal imposes any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis. Use of any colocation service is completely voluntary, and each market participant is able to determine whether to use colocation services based on the requirements of its business operations.</P>

                         17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) requires a self-regulatory organization to give the Commission written notice of its intent to file the proposed rule change, along with a brief description and text of the proposed rule change, at least five business days prior to the date of filing of the proposed rule change, or such shorter time as designated by the Commission. The Exchange has satisfied this requirement.

                    <FTREF/>
                     permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (
                    <E T="03">e.g.,</E>
                     greater than 10kW) without delay once a fee is established for such cabinets. The Commission believes that the proposed rule change presents no novel legal or regulatory issues and that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                    Currently, the Exchange offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>
                <HD SOURCE="HD3">2. Statutory Basis</HD>
                <P>
                    The Exchange believes that its proposal is consistent with Section 6(b) 
                    <PRTPAGE P="16068"/>
                    of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of Section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).
                    <SU>11</SU>
                    <FTREF/>
                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

                     As noted above, the Exchange offers the Cabinet Proximity Option program as a convenience, not a necessity, and it is only for those customers that choose to collocate directly with the Exchange.

                <P>Nothing in the proposal imposes any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis. Use of any colocation service is completely voluntary, and each market participant is able to determine whether to use colocation services based on the requirements of its business operations.</P>

In addition, Rule 19b-4(f)(6) requires a self-regulatory organization to give the Commission written notice of its intent to file the proposed rule change, along with a brief description and text of the proposed rule change, at least five business days prior to the date of filing of the proposed rule change, or such shorter time as designated by the Commission. The Exchange has satisfied this requirement.

                    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the Act 
                    <SU>15</SU>
                    <FTREF/>

                    <FTREF/>
                     permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (
                    <E T="03">e.g.,</E>
                     greater than 10kW) without delay once a fee is established for such cabinets. The Commission believes that the proposed rule change presents no novel legal or regulatory issues and that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                    Currently, the Exchange offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

                         Due to heightened demand for power and cabinets, NYSE established certain procedures related to PNU cabinet conversion and restrictions on new PNU cabinet offerings. NYSE adopted a policy that, if unallocated cabinet inventory is at or below 40 cabinets, new PNU cabinets are not offered. However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>
                <HD SOURCE="HD3">2. Statutory Basis</HD>
                <P>
                    The Exchange believes that its proposal is consistent with section 6(b) of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).
                    <SU>11</SU>
                    <FTREF/>
                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

                <P>Nothing in the proposal imposes any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis. Use of any colocation service is completely voluntary, and each market participant is able to determine whether to use colocation services based on the requirements of its business operations.</P>

The Exchange has satisfied this requirement.

                     permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (
                    <E T="03">e.g.,</E>
                     greater than 10kW) without delay once a fee is established for such cabinets. The Commission believes that the proposed rule change presents no novel legal or regulatory issues and that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                <P>
                    Currently, Rule 7.31(a)(2)(B) provides that a Limit Order to buy (sell) will be rejected if it is priced at or above (below) the greater of $0.15 or a specified percentage away from the National Best Offer (National Best Bid) (“NBO” and “NBB,” respectively),
                    <SU>3</SU>
                    <FTREF/>
                     and that Limit Order Price Protection will not be applied to an incoming Limit Order to buy (sell) if there is no NBO (NBB).

                    <P>
                        <SU>3</SU>
                         For securities with a reference price between $0.00 and $25.00, the specified percentage is 10%; for securities with a reference price between $25.01 and $50.00, the specified percentage is 5%; and for securities with a reference price greater than $50.00, the specified percentage is 3%.

                <P>
                    The Exchange has recently received requests from market participants to modify this rule so that during the Core Trading Session, Limit Order Price Protection would apply even when no contra-side NBB or NBO has been established. In such cases, market participants have suggested that the Limit Order Price Protection calculation should use an alternate reference price, such as the last consolidated round-lot price of the trading day or the prior trading day's official closing price. That way, even if no contra-side NBB or NBO has been established, the Exchange would still apply Limit Order Price Protection using the best-available alternate reference price, thereby offering market participants greater protections against the execution of Limit Orders with aberrant prices during the Core Trading Session. The Exchange is aware that the Limit Order Price Protection rule on the MIAX Pearl equities exchange (“MIAX Pearl”) currently features such a hierarchy of reference prices, so that Limit Order Price Protection is applied to all Limit 
                    <PRTPAGE P="16072"/>
                    Orders, even where no contra-side NBB or NBO has been established.

                        <SU>4</SU>
                         Under current MIAX Pearl rules, a Limit Order to buy (sell) will be rejected if it is priced at or above (below) the greater of a specified dollar and percentage away from (1) the PBO (PBB), or, if unavailable, (2) the consolidated last sale price disseminated during the Regular Trading Hours on trade date, or, if unavailable, (3) the prior day's Official Closing Price.

                <P>
                    In light of these requests from market participants, the Exchange now proposes to amend Rule 7.31(a)(2)(B) to provide a hierarchy of reference prices against which Limit Order Price Protection would apply during the Core Trading Session. As in the current rule, during the Core Trading Session, a Limit Order to buy (sell) would be rejected if it is priced at or above (below) the greater of $0.15 or a specified percentage (as set forth in the accompanying table) away from the NBO (NBB). But if such NBO (NBB) has not yet been established, the Exchange would use as the reference price the last consolidated round-lot price of that trading day, or, if none, the prior trading day's Official Closing Price.
                    <SU>5</SU>
                    <FTREF/>
                     This proposal is substantively identical to an immediately-effective rule change recently filed by the Exchange's affiliate exchange, NYSE American LLC (“NYSE American”).

                        <SU>5</SU>
                         The Exchange's proposed hierarchy of reference prices is substantially similar to the hierarchy in the MIAX Pearl rules. The only differences are that the Exchange's proposal (a) would continue to reference the NBO (NBB) instead of the PBO (PBB), as the Exchange's Limit Order Price Protection mechanism has always done; and (b) unlike the MIAX Pearl rule, which permits an odd lot to serve as “the consolidated last sale price disseminated during the Regular Trading Hours on trade date,” the Exchange's proposal would instead use the last consolidated round-lot price of that trading day, which the Exchange believes is a better indication of actual market conditions. Both the MIAX Pearl rule and the Exchange's proposed rule would use the prior trading day's Official Closing Price as the reference price of last resort.

                <P>As in the NYSE American filing, the Exchange does not propose for this change to apply during the Early and Late Trading Sessions. This is because with respect to both the Early and Late Trading Sessions, there is a higher likelihood that overnight news developments may move the market more than the percentages specified in the Limit Order Price Protection rule. If, in the absence of an NBO (NBB), such percentages were applied to the prior trading day's Official Closing Price, this might lead the Exchange to reject orders that are appropriately trying to establish a quote at the new market level. For this reason, the Exchange believes the current rule should continue to govern during the Early and Late Trading Sessions, such that if there is no contra-side NBO (NBB), Limit Order Price Protection will not be applied.</P>
                <P>Accordingly, the Exchange proposes to amend and reorganize Rule 7.31(a)(2)(B) into three sub-sections, with sub-section (i) describing the relevant reference prices during the Core Trading Session, sub-section (ii) describing the relevant reference price during the Early and Late Trading Sessions, and sub-section (iii) describing the balance of the current rule.</P>
                <P>Specifically, the Exchange proposes that new sub-section (i) of Rule 7.31(a)(2)(B) would provide that during the Core Trading Session, a Limit Order to buy (sell) will be rejected if it is priced at or above (below) the greater of $0.15 or a specified percentage (as set forth in the accompanying table) away from “(a) the NBO (NBB), or, if none, (b) the last consolidated round-lot price of that trading day, or, if none, (c) the prior trading day's Official Closing Price.”</P>
                <P>The Exchange proposes that new sub-section (ii) of the rule would provide that during the Early and Late Trading Sessions, a Limit Order to buy (sell) will be rejected if it is priced at or above (below) the greater of $0.15 or a specified percentage (as set forth in the accompanying table) away from the NBO (NBB), and that Limit Order Price Protection will not be applied to an incoming Limit Order to buy (sell) if there is no NBO (NBB).</P>
                <P>Finally, the Exchange proposes that the balance of the current rule be moved to new sub-section (iii) after the new subtitle “Applicability.”</P>
                <P>The Exchange does not propose to make any other changes to the rule, nor does it propose any changes to the $0.15 or specified percentages used in the calculation of Limit Order Price Protection.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange anticipates implementing the proposed change in the first quarter of 2024 and, in any event, will implement the proposed rule change no later than the end of June 2024. The Exchange will announce the timing of such changes by Trader Update.</P>

                <P>
                    The Exchange believes that the proposed rule change is consistent with section 6(b) of the Act,
                    <SU>7</SU>
                    <FTREF/>
                     in general, and with section 6(b)(5),

                    <FTREF/>
                     in particular, because it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest.

                </FTNT>
                <P>
                    The Exchange believes that the proposed change would remove impediments to and perfect the mechanism of a free and open market and a national market system, and in general, protect investors and the public interest, because the use a substantially similar hierarchy of reference prices for the application of Limit Order Price Protection when no contra-side NBO or NBB has been established is currently in effect on MIAX Pearl and is the subject of an immediately-effective rule filing on NYSE American, and therefore is not novel.
                    <SU>9</SU>
                    <FTREF/>
                     The Exchange further believes that the proposed change would enhance the Exchange's Limit Order Price Protection mechanism during the Core Trading Session, because it would apply using the best-available alternate reference price when a contra-side NBO or NBB has not been established, thereby offering market participants greater protection from aberrant prices and improving continuous trading and price discovery. In addition, the proposal to enhance Limit Order Price Protection by adding alternative reference prices to apply to the Core Trading Session would assist with the maintenance of fair and orderly markets because such mechanisms protect investors from potentially receiving executions away from the prevailing market prices.

                    The Exchange also believes that it would protect investors and the public interest for the Exchange to maintain the current Limit Order Price Protection rule for the Early and Late Trading Sessions. With respect to both the Early and Late Trading Sessions, there is a higher likelihood that overnight news developments may move the market more than the percentages specified in the Limit Order Price Protection rule. If, in the absence of an NBO (NBB), such percentages were applied to the prior trading day's Official Closing Price, this might lead the Exchange to reject orders that are appropriately trying to establish a quote at the new market level.

                <P>The Exchange believes that the proposed rule change will not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.

                    Currently, the Exchange offers a Cabinet Proximity Option program where, for a monthly fee, customers can obtain an option for future use on available, unused cabinet space in proximity to their existing equipment. Cabinets reserved under the Cabinet Proximity Option program are unused cabinets that customers reserve for future use and can be converted to a powered cabinet at the customer's request. Under the program, customers can reserve up to maximum of 20 cabinets that the Exchange endeavors to provide as close as reasonably possible to the customer's existing cabinet space, taking into consideration power availability within segments of the datacenter and the overall efficiency of use of datacenter resources as determined by the Exchange. Should reserved datacenter space be needed for use, the reserving customer will have three business days to formally contract with the Exchange for full payment for the reserved cabinet space in contention or it will be reassigned. In making determinations to require exercise or relinquishment of reserved space as among numerous customers, the Exchange will take into consideration several factors, including: proximity between available reserved cabinet space and the existing space of a customer seeking additional space for actual cabinet usage; a customer's ratio of cabinets in use to those reserved; the length of time that a particular reservation(s) has been in place; and any other factor that the Exchange deems relevant to ensure overall efficiency in use of the datacenter space.

                     The purpose of the proposed rule change is to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW, in addition to those reservations currently offered under the program.

                    <FTREF/>
                     the Exchange has yet to offer reservations under the Cabinet Proximity Option program for cabinets with power densities greater than 10 kW (despite offering cabinets with power densities greater than 10 kW). The Exchange now wishes to offer the Cabinet Proximity Option program for these higher power density cabinets. Similar to the Exchange's Cabinet Proximity Option program, the New York Stock Exchange LLC (“NYSE”) offers “PNU cabinets,” which are reserved cabinets that are not active and can be converted to powered, dedicated cabinets when the user requests.

Medium density cabinets are cabinets with power densities greater than 2.88 kW and less than or equal to 5 kW. Medium/High density cabinets are cabinets with power densities greater than 5 kW and less than or equal to 7 kW.

                         Due to heightened demand for power and cabinets, NYSE established certain procedures related to PNU cabinet conversion and restrictions on new PNU cabinet offerings. NYSE adopted a policy that, if unallocated cabinet inventory is at or below 40 cabinets, new PNU cabinets are not offered. However, when the unallocated cabinet inventory is more than 40 cabinets, NYSE may continue to offer PNU cabinets.

                <P>The Exchange offers the Cabinet Proximity Option program as a convenience to customers. No firms are required to reserve cabinets via the Cabinet Proximity Option program and it is only for those customers that choose to collocate directly with the Exchange. Participants can avoid reserving cabinets under this program (and the related fee) by (1) collocating but not reserving space in advance of needing it; (2) ordering cabinet space immediately and paying cabinet fees (without reserving in advance); (3) collocating indirectly through a vendor to defray costs; or (4) not collocating at all.</P>
                <HD SOURCE="HD3">Implementation</HD>
                <P>The Exchange intends to submit a fee filing in the future to establish related fees in the existing Cabinet Proximity Option Fees, in General 8, Section 1(d). Implementation of the proposal described herein to offer the Exchange's Cabinet Proximity Option program for cabinets with power densities greater than 10 kW would coincide with the subsequent fee filing.</P>

                <P>
                    The Exchange believes that its proposal is consistent with section 6(b) of the Act,
                    <SU>9</SU>
                    <FTREF/>
                     in general, and furthers the objectives of section 6(b)(5) of the Act,
                    <SU>10</SU>
                    <FTREF/>
                     in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general to protect investors and the public interest. The proposal would provide customers with the ability to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for those cabinets with power densities greater than 10 kW. Customers are currently able to obtain an option for future use on available, unused cabinet space in proximity to their existing equipment for smaller cabinets (
                    <E T="03">e.g.,</E>
                     for cabinets with power densities less than 10 kW). The proposal is consistent with the Act because it would clarify, in conjunction with a subsequent fee filing, that reservations under the Cabinet Proximity program are available for cabinets with power densities greater than 10 kW. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, which may be offered for cabinets of all power densities (when the unallocated cabinet inventory is more than 40 cabinets).
                    <SU>11</SU>
                    <FTREF/>
                     Furthermore, the proposal would benefit the public interest by providing customers more reservation options to choose from, thereby enhancing their ability to tailor their colocation operations to the requirements of their business operations.

                <P>Nothing in the proposal imposes any burden on the ability of other exchanges to compete. The Exchange operates in a highly competitive market in which exchanges and other vendors offer colocation services as a means to facilitate the trading and other market activities of those market participants who believe that colocation enhances the efficiency of their operations. The Cabinet Proximity Option program is comparable to PNU cabinets offered by NYSE, as discussed above.</P>
                <P>Nothing in the Proposal burdens intra-market competition because the Cabinet Proximity Option program is available to any customer and customers that wish to make reservations pursuant to the Cabinet Proximity Option program can do so on a non-discriminatory basis. Use of any colocation service is completely voluntary, and each market participant is able to determine whether to use colocation services based on the requirements of its business operations.</P>

The Exchange has requested that the Commission waive the 30-day operative delay so that the proposal may become operative immediately upon filing. The Exchange states that a waiver of the operative delay would permit the Exchange to offer reservations under the Cabinet Proximity Option program for cabinets with greater power densities (

                     greater than 10kW) without delay once a fee is established for such cabinets. The Commission believes that the proposed rule change presents no novel legal or regulatory issues and that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the 30-day operative delay and designates the proposed rule change operative upon filing.

                <P>
                    In 2020, in order to assist ETP Holders' efforts to manage their risk, the Exchange amended its rules to add Rule 7.19 (Pre-Trade Risk Controls),
                    <SU>3</SU>
                    <FTREF/>
                     which established a set of optional pre-trade risk controls by which Entering Firms and their designated Clearing Firms 
                    <SU>4</SU>
                    <FTREF/>
                     could set credit limits and other pre-trade risk controls for an Entering Firm's trading on the Exchange and authorize the Exchange to take action if those credit limits or other pre-trade risk controls are exceeded. These pre-trade risk controls include a Gross Credit Risk Limit, which is defined in Rule 7.19(b)(1) as “a pre-established maximum daily dollar amount for purchases and sales across all symbols, where both buy and sell orders are counted as positive values.” The current version of Rule 7.19(b)(1) specifies that both open and executed orders are considered: “[f]or purposes of calculating the Gross Credit Risk Limit, unexecuted orders in the Exchange Book, orders routed on arrival pursuant to Rule 7.37(a)(1), and executed orders are included.”

                         The terms “Entering Firm” and “Clearing Firm” are defined in Rule 7.19.
                    </P>
                </FTNT>
                <P>The Exchange has recently received several requests from market participants to create two additional Gross Credit Risk Limit risk controls: one that includes only open orders and another that includes only executed orders. Market participants have explained that Entering Firms and Clearing Firms would benefit from having more granular gross credit risk controls available, which would allow them to set limits and breach actions based solely on open orders or executed orders, in addition to the Exchange's existing Gross Credit Risk Limit that includes both open and executed orders.</P>
                <P>
                    The Exchange notes that the MIAX Pearl equities exchange (“MIAX Pearl”) currently offers risk controls substantially similar to those proposed here. Specifically, MIAX Pearl offers its “Equity Members” and their “Clearing Members” the option to use a “Gross Notional Trade Value” risk check, which includes only executed orders, and a “Gross Notional Open Value” risk check, which includes only unexecuted orders, in addition to a “Gross Notional Open and Trade Value” risk check, for which both executed and unexecuted orders are included.

                    <FTREF/>
                     As such, market participants are already familiar with these various gross credit risk checks, such that the ones proposed by the Exchange in this filing are not novel.

                </FTNT>
                <P>In light of these requests, the Exchange proposes to amend Rule 7.19(b)(1) to rename the existing Gross Credit Risk Limit as “Gross Credit Risk Limit—Open + Executed,” and to add two additional risk limits: “Gross Credit Risk Limit—Open Only” and “Gross Credit Risk Limit—Executed Only.”</P>
                <P>Specifically, the Exchange proposes to amend and reorganize Rule 7.19(b)(1) as follows. First, the Exchange would amend the language in the first sentence of the rule to refer to plural Gross Credit Risk Limits, instead of just one. At the end of the first sentence, the Exchange would add that “[a]vailable Gross Credit Risk Limits include” the three types described in new sub-sections (A), (B), and (C).</P>
                <P>Proposed sub-section (A) would define the “Gross Credit Risk Limit—Open + Executed” risk check to include unexecuted orders in the Exchange Book, orders routed on arrival pursuant to Rule 7.37(a)(1), and executed orders (just as the current Gross Credit Risk Limit does).</P>
                <P>Proposed sub-section (B) would define the “Gross Credit Risk Limit—Open Only” risk check to include only unexecuted orders in the Exchange Book and orders routed on arrival pursuant to Rule 7.37(a)(1).</P>
                <P>Proposed sub-section (C) would define the “Gross Credit Risk Limit—Executed Only” risk check to include executed orders only.</P>
                <P>In addition, the Exchange proposes to make a conforming change to section (c)(1)(B) of the rule, to make plural the current singular reference to “Gross Credit Risk Limit.”</P>
                <P>As with the Exchange's existing risk controls, use of the pre-trade risk controls proposed herein would be optional. The Exchange proposes no other changes to Rule 7.19 or its Commentary.</P>
                <HD SOURCE="HD3">Continuing Obligations of ETP Holders Under Rule 15c3-5</HD>
                <P>
                    The proposed Pre-Trade Risk Controls described here are meant to supplement, and not replace, the ETP Holders' own internal systems, monitoring, and procedures related to risk management. The Exchange does not guarantee that these controls will be sufficiently comprehensive to meet all of an ETP Holder's needs, the controls are not designed to be the sole means of risk management, and using these controls will not necessarily meet an ETP Holder's obligations required by Exchange or federal rules (including, without limitation, the Rule 15c3-5 under the Act

                     (“Rule 15c3-5”)). Use of the Exchange's Pre-Trade Risk Controls will not automatically constitute compliance with Exchange or federal rules and responsibility for compliance with all Exchange and SEC rules remains with the ETP Holder.

                    Specifically, the Exchange believes that the proposed rule change will remove impediments to and perfect the mechanism of a free and open market and a national market system because the proposed additional Pre-Trade Risk Controls would provide Entering Firms and Clearing Firms with enhanced abilities to manage their risk with respect to orders on the Exchange. The proposed additional Pre-Trade Risk Controls are not novel; they are based on existing risk settings already in place on MIAX Pearl and market participants are already familiar with the types of protections that the proposed risk controls afford.

                <P>In addition, the Exchange believes that the proposed rule change will protect investors and the public interest because the proposed additional Pre-Trade Risk Controls are a form of impact mitigation that will aid Entering Firms and Clearing Firms in minimizing their risk exposure and reduce the potential for disruptive, market-wide events. The Exchange understands that ETP Holders implement a number of different risk-based controls, including those required by Rule 15c3-5. The controls proposed here will serve as an additional tool for Entering Firms and Clearing Firms to assist them in identifying any risk exposure. The Exchange believes the proposed additional Pre-Trade Risk Controls will assist Entering Firms and Clearing Firms in managing their financial exposure which, in turn, could enhance the integrity of trading on the securities markets and help to assure the stability of the financial system.</P>
                <P>Finally, the Exchange believes that the proposed rule change does not unfairly discriminate among the Exchange's ETP Holders because use of the proposed additional Pre-Trade Risk Controls is optional and is not a prerequisite for participation on the Exchange.</P>
                <HD SOURCE="HD2">B. Self-Regulatory Organization's Statement on Burden on Competition</HD>
                <P>The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. In fact, the Exchange believes that the proposal will have a positive effect on competition because, by providing Entering Firms and Clearing Firms additional means to monitor and control risk, the proposed rule will increase confidence in the proper functioning of the markets. The Exchange believes the proposed additional Pre-Trade Risk Controls will assist Entering Firms and Clearing Firms in managing their financial exposure which, in turn, could enhance the integrity of trading on the securities markets and help to assure the stability of the financial system. As a result, the level of competition should increase as public confidence in the markets is solidified.</P>

The latter category includes: items of the same kind as those on multilateral lists but falling below the control list parameters when it is determined that such items have the potential of making 
                    <PRTPAGE P="16079"/>

                <P>Accordingly, pursuant to section 3 of the Act, the following measures are imposed on these persons:</P>
                <P>1. No department or agency of the U.S. Government may procure or enter into any contract for the procurement of any goods, technology, or services from these foreign persons, except to the extent that the Secretary of State otherwise may determine;</P>

                         Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 23, 2023 under docket number FAA-2020-0385. The collection involves information on the availability of airport gates and related facilities, leasing and sub-leasing arrangements, gate-use requirements, gate-assignment policy, financial constraints, airport controls over air- and ground-side capacity, and whether the airport intends to build or acquire gates that would be used as common facilities. The information to be collected is necessary because it is required by statute that a covered airport submits a written competition plan to the Secretary/Administrator in order to receive approval to impose a Passenger Facility Charge (PFC) or to receive a grant under the Airport Improvement Program (AIP) or Bipartisan Infrastructure Law (BIL).

                    <E T="04">Federal Register</E>
                     Notice with a 60-day comment period soliciting comments on the following collection of information was published on June 23, 2023 (88 FR 41184). This collection asks the public agencies to report on the availability of airport gates and related facilities, leasing and sub-leasing arrangements, gate-use requirements, gate-assignment policy, financial constraints, airport controls over air- and ground-side capacity, and whether the airport intends to build or acquire gates that would be used as common facilities. The DOT/FAA uses information submitted in response to this requirement to carry out the intent of §§ 40117(k) and 47106(f), which is to assure that a covered airport has, and implements, a plan to provide opportunities for competitive access by new entrant air carriers or air carriers seeking to expand. The information allows FAA to assess the competitive environment at airports and provide feedback to the airport on suggested improvements.
                </P>
                <P>Once an airport qualifies as covered the collection frequency is as follows: it is required to send its initial competition plan as soon as possible. Upon approval by the FAA of the initial competition plan, the public agency must submit two (2) competition plan updates, in 18-month intervals, while it remains a covered airport. Once an airport has submitted, and the FAA has approved, its initial competition plan and the subsequent two (2) updates, a competition plan is only required if the airport (1) has filed a competitive access report as required by Section 424 of Vision 100, codified as 49 U.S.C. 47107(s) stating it has denied access to an air carrier for gates or facilities within the last six months; or (2) is executing a new master lease and use agreement, or significantly amending a lease and use agreement, including an amendment due to use of PFC financing of gates. If an airport loses its status as a covered airport, no further competition plan updates are required unless or until the airport becomes covered again.</P>

                    <P>The FHWA issued regulations establishing minimum standards and requirements for certain electric vehicle (EV) chargers. Subsequent to the publication of this final rule, the Society of Automotive Engineers (SAE) published a Technical Information Report for a new connector standard, known as J3400, which multiple automakers have announced an intention to adopt in the coming years. To ensure the effective implementation of programs that are subject to the minimum standards and requirements and to inform a potential update to the minimum standards, FHWA, in coordination with the Joint Office of Energy and Transportation, is seeking additional information in five areas: on the expectations surrounding market availability for J3400 within EVs and EV chargers; on the technical compatibility of J3400 with existing regulations and safety considerations; on considerations regarding challenges and benefits of the implementation of J3400 at charging stations; on market demands for the continued availability of Combined Charging System (CCS) and J1772 connectors; and potential options for performance-based standards that can reduce the need for future regulatory updates or changes as technology evolves.</P>

                <P>
                    On February 28, 2023, FHWA published a final rule 
                    <SU>1</SU>
                    <FTREF/>
                     establishing minimum standards and requirements for projects funded under the National Electric Vehicle Infrastructure (NEVI) Formula Program and projects for the construction of publicly accessible electric vehicle (EV) chargers that are funded with funds made available under Title 23, United States Code, including any EV charging infrastructure project funded with Federal funds that is treated as a project on a Federal-aid highway. As outlined in statute, the purpose of the NEVI Formula Program is to “provide funding to States to strategically deploy EV charging infrastructure and to establish an interconnected network to facilitate data collection, access, and reliability.” This purpose is satisfied by creating a convenient, affordable, reliable, and equitable network of chargers throughout the country. Prior to the establishment of this rule, there were no national standards for the installation, operation, or maintenance of EV charging stations, and wide disparities exist among EV charging stations. The final rule enables States or other designated recipients to implement federally funded charging station projects in a standardized fashion in order to build a convenient, accessible, reliable, and equitable charging network across the country that can be utilized by all EVs regardless of vehicle brand. Such standards provide reliable expectations for travel in an EV across and throughout the United States.

                         On November 15, 2021, the Bipartisan Infrastructure Law (BIL) was enacted as the Infrastructure Investment and Jobs Act (IIJA), Public Law 117-58. To ensure standardization for a nationwide network of EV chargers, the BIL mandated the creation of a set of minimum standards and requirements for electric vehicle chargers which were finalized under 23 CFR 680 by FHWA on February 28, 2023, at 88 FR 12724.
                    </P>
                </FTNT>
                <P>
                    As part of this rule, FHWA regulates the connector type used on EV chargers through 23 CFR 680.106(c) which states, “All charging connectors must meet applicable industry standards. Each Direct Current Fast Charger (DCFC) charging port must be capable of charging any Combined Charging System (CCS)-compliant vehicle and each DCFC charging port must have at least one permanently attached CCS Type 1 connector. In addition, permanently attached CHAdeMO (
                    <E T="03">www.chademo.com</E>
                    ) connectors can be provided using only FY2022 NEVI Funds. Each Alternating Current (AC) Level 2 charging port must have a permanently attached J1772 connector and must charge any J1772-compliant vehicle.” The final rule allows permanently attached non-proprietary connectors to be provided on each charging port so long as each DCFC charging port has at least one permanently attached CCS Type 1 connector and is capable of charging a CCS-compliant vehicle.
                </P>
                <P>
                    Subsequent to the publication of 23 CFR part 680, the Society of Automotive Engineers (SAE) published a Technical Information Report (TIR) 
                    <SU>2</SU>
                    <FTREF/>
                     in December 2023 which provided information on the J3400 EV charging connector standard (also known as the North American Charging Standard Electric Vehicle Coupler). J3400 utilizes the same connector and pins for AC and DC charging; the publication of a new connector standard has implications for both vehicles and chargers. To date, J3400 has only been utilized in a proprietary implementation by one auto manufacturer and its charging network. However, several additional auto manufacturers have announced an intention to adopt J3400 with full vehicular integration beginning in 2025, and through adapters as early as 2024. Multiple charging equipment manufacturers have also publicly committed to adopting the J3400 connector on chargers. The FHWA, in coordination with the Joint Office of Energy and Transportation, seeks information to better understand how the introduction and adoption of J3400 will impact the EV charging industry, automakers, and EV charging consumers and to inform potential updates to the minimum standards.

                <P>To ensure FHWA has the most comprehensive and current information available, FHWA is specifically seeking detailed comments on the expectations surrounding market availability for J3400 within EVs and EV chargers, on the technical compatibility of J3400 with existing regulations, on considerations regarding challenges and benefits of the implementation of J3400 at charging stations, on market demands for the continued availability of CCS and J1772 connectors, and on potential options for performance-based standards that can reduce the need for future regulatory updates or changes as technology evolves. The FHWA is also interested in obtaining more information on the impact of the publication of the J3400 TIR in order to assess how the minimum standards and requirements for EV charging can address the evolving needs of EV charging consumers and industry.</P>
                <P>
                    The FHWA additionally requests information on what performance-based standards would best facilitate competition and innovation in EV markets, consistent with the Office of Information and Regulatory Affairs “Guidance on Accounting for 
                    <PRTPAGE P="16083"/>
                    Competition Effects When Developing and Analyzing Regulatory Actions.”

                    <FTREF/>
                     The term “performance-based standards” in this context refers to standards that specify a level of service and types of vehicles a charger must support without specifying specific connectors.

                     Include a specified number of each type of connector (J3400 and CCS Type 1/J1772) at each charging station.
                </P>
                <P>Under Approach 2, what is the optimal ratio of J3400 connectors to CCS/J1772 connectors? Why?</P>

                <P>b. Are there performance-based alternatives to specifying charging standards and communication standards (such as J3400, J1772, or ISO 15118) by reference that would support a convenient, affordable, reliable, and equitable EV charging network while reducing the need for future refinement to federal regulations?</P>
                <P>
                    c. Which performance-based alternative (

                     standards that specify a level of service and types of vehicles a charger must support without specifying specific connectors) would best facilitate competition and innovation in EV markets? Which performance-based alternatives have the potential to harm competition, create consumer lock in, or otherwise erect or increase entry barriers?
                </P>
                <P>d. Should performance-based standards include requirements for achieving Key Performance Indicators most important to EV customers? If so, what should those Key Performance Indicators be?</P>

                <P>a. Is there anything additionally that should be considered related to EV charging connector standards and technologies that is not covered in the above questions?</P>

                     T.D. 8096 provides final regulations relating to product liability losses and accumulations for the payment of reasonable anticipated product liability losses. Changes to the applicable tax law were made by the Revenue Act of 1978. Generally, a taxpayer who sustains a product liability loss must carry the loss back 10 years. However, a taxpayer may elect to have such loss treated as a regular net operating loss under section 172. If desired, such election is made by attaching a statement to the tax return. This statement will enable the IRS to monitor compliance with the statutory requirements.

Under section 6511(h), the statute of limitations on claims for credit or refund is suspended for any period of an individual taxpayer's life during which the taxpayer is unable to manage his or her financial affairs because of a medically determinable mental or physical impairment, if the impairment can be expected to result in death, or has lasted (or can be expected to last) for a continuous period of not less than 12 months.

                <HD SOURCE="HED">National Consumer Protection Week, 2024</HD>
                <PRES>By the President of the United States of America</PRES>
                <PROC>A Proclamation</PROC>
                <FP>As my Administration continues to build an economy that works for everyone, we cannot let fraud, cybercrimes, or unfair business practices interrupt the progress we have made. During National Consumer Protection Week, we recommit to protecting the rights of consumers and spreading awareness about the resources people have to defend themselves from predatory acts.</FP>
                <FP>Since I took office, we have made enormous progress in building an economy from the middle out and the bottom up. To date, we have created nearly 15 million jobs, driven stable economic growth, and brought down inflation by two-thirds from its peak. Still, I know we have more work to do to protect the progress we have made by defending American consumers from unfair business practices.</FP>
                <FP>In my first year in office, I issued an Executive Order on Promoting Competition in the American Economy, which directs and encourages Federal agencies to find ways to address powerful corporations' use of their market dominance to inflate prices of consumer goods and services. These corporations are also decreasing the quality of goods and services, deterring innovation, and limiting job mobility. Since then, agencies across the Federal Government have taken decisive action to encourage competition and lower costs for American households.</FP>
                <FP>The Department of Justice and the Federal Trade Commission (FTC) are cracking down on anticompetitive mergers, price fixing and price gouging, and other unfair practices that harm consumers. The Department of Agriculture has joined the effort to enforce antitrust and consumer protection laws in food and agriculture, which not only protect American families but farmers as well. At the same time, the FTC is working on a rule that would, if finalized as proposed, put an end to noncompete agreements, which restrict 30 million workers from switching jobs, even if they have opportunities that offer better pay and benefits. The FTC is also engaged in a rulemaking that proposes to require that companies make it as easy to cancel an online enrollment as it was to sign up so you are not left paying unwanted subscription fees because of a difficult cancellation process. The FTC is working with law enforcement to counter predatory student loan scams, mortgage scams, and identity theft.</FP>
                <FP>
                    My Administration is fighting to eliminate hidden junk fees that some banks, airlines, health care companies, and other organizations use to rip off their customers. Since 2021, 15 of the 20 largest banks have responded to my call to stop charging customers for bounced checks and reduce overdraft fees, saving Americans $5.5 billion annually in eliminated junk fees. The Consumer Financial Protection Bureau (CFPB) has proposed a rule that will slash credit card late fees from an average of $31 when I took office to a new cap of $8, which will save Americans more than $9 billion annually. The CFPB is also taking steps to cut the average overdraft fee by more than half, down from its typical amount of over $30, a move that would save $150 per year for the more than 20 million households that pay these fees. The CFPB has also banned banks and credit unions from charging fees for basic services, like checking an account balance 
                    <PRTPAGE P="15950"/>
                    or retrieving old bank records. In addition, it has proposed a new rule that would make it easier for customers to switch banks, encouraging them to compete for customers based on the quality of their services.
                </FP>
                <FP>The Department of Labor proposed a new rule that would, if finalized as proposed, minimize junk fees in retirement products by requiring financial advisers to provide retirement advice in the best interest of the saver. The Department of Health and Human Services and the Department of the Treasury have proposed a rule that would protect Americans from getting ripped off by health plans offering junk insurance that discriminate based on pre-existing conditions and trick consumers into buying insurance that provides little or no coverage when they need it most. Further, the Department of Transportation has challenged airlines to improve unfair business practices. Some airlines have already responded by eliminating fees that charge parents just to sit next to their child on a plane. Many have also begun guaranteeing free rebooking and reimbursement for hotels, meals, and ground transportation if a flight cancellation or delay is the airline's fault. Just last year, we saw the lowest rate of flight cancellations in a decade.</FP>
                <FP>The FTC has enhanced its translation resources to make it easier for consumers to submit fraud reports and learn how to spot and avoid scams in languages other than English. Meanwhile, we are continuing to work with partners across the Government and in our communities to amplify and expand language access for consumers. Last year, the FTC proposed a rule that would ban hidden fees across the economy and require all companies to show consumers the all-in pricing of products upfront.</FP>
                <FP>The American people should never be played like suckers. It is up to each of us to protect one another from harmful anticompetitive business practices. This National Consumer Protection Week, I encourage every American to visit consumer.ftc.gov to learn more about the resources available to defend the rights of consumers. I also encourage people to report cases of suspected fraud, issues with a consumer financial product, aggressive debt collection, inaccurate credit reporting, or unfair medical billing and other issues by visiting consumerfinance.gov/complaint online.</FP>
                <FP>NOW, THEREFORE, I, JOSEPH R. BIDEN JR., President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim March 3, 2024, through March 9, 2024, as National Consumer Protection Week. I call upon government officials, industry leaders, and advocates across the Nation to share information about consumer protection and provide our citizens with information about their rights as consumers.</FP>

                <HD SOURCE="HED">Read Across America Day, 2024</HD>
                <PRES>By the President of the United States of America</PRES>
                <PROC>A Proclamation</PROC>
                <FP>On Read Across America Day, we celebrate the power of literacy to expand our minds and our understanding of the world around us. We salute all the parents, educators, authors, librarians, and mentors who encourage our children to read, and we appreciate the literature that dares them to think big.</FP>
                <FP>For so many children, their dreams begin with a book. Whether it is through the stories they listen to at bed time or a trip to the local library, books introduce children to new ideas, cultures, and perspectives. They feed the imagination and stoke the fires of innovation that help them understand our world as it is and pioneer ways to make it better. I know firsthand how reading can change lives: the First Lady, a lifelong book lover, pursued a career as an educator because she wanted to share the gift of reading with people who “didn't know that joy.” As a community college professor, she continues to share that gift and remains committed to supporting all the teachers who do the same for their students.</FP>
                <FP>The First Lady and I recognize there is still more work to do to improve literacy across the country. For more than a decade, studies show that reading competency of American students has been on the decline—and the impact of the COVID-19 pandemic only made things worse. That is why, since day one of my Administration, we have been committed to supporting educators and improving literacy—from our youngest readers to adults.</FP>
                <FP>To get our schools back open and running during the pandemic, my American Rescue Plan secured $130 billion, putting more teachers in our classrooms and more counselors in our schools. This funding is providing high-quality tutoring, expanding summer and after-school programming, and increasing student engagement. Over the past 3 years, school districts have added more than 610,000 educators and staff. Our National Partnership for Student Success is working to add another 250,000 caring adults in tutoring, mentoring, and other critical support roles. That equals hundreds of thousands of additional professionals who are giving students the support they deserve.</FP>
                <FP>We also know that early education is a powerful stepping stone for academic success. Research shows that children who start school at 3 and 4 years old are more likely to graduate from high school and further their education. It is a big reason why I am working to ensure that every child in America has access to high-quality preschool.</FP>
                <FP>We are also supporting adults in their efforts to become better readers through my Administration's Adult Education State Grants. These grants support adult literacy programs and provide the skills and resources needed to gain employment—from obtaining a secondary school diploma to transitioning to a postsecondary school.</FP>
                <FP>
                    This Read Across America Day, we must also acknowledge a difficult truth—that our children are growing up in a country where some extremist politicians are banning books in grade schools and high schools. In America, 
                    <PRTPAGE P="15954"/>
                    we do not ban books. Rather, we celebrate the full diversity of stories and perspectives—and their potential to expand our horizons.
                </FP>
                <FP>Dr. Seuss once wrote, “The more that you read, the more things you will know. The more that you learn, the more places you'll go.” Today, may we celebrate the power that is unleashed by reading—discovering the comfort of words in times of sorrow, finding inspiration to fuel our imagination, or having a clear-eyed understanding of our past so we can forge a future of limitless possibilities.</FP>
                <FP>NOW, THEREFORE, I, JOSEPH R. BIDEN JR., President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim March 2, 2024, as Read Across America Day. I call upon children, families, educators, librarians, public officials, and all the people of the United States to observe this day with appropriate programs, ceremonies, and activities.</FP>
                <FP>IN WITNESS WHEREOF, I have hereunto set my hand this first day of March, in the year of our Lord two thousand twenty-four, and of the Independence of the United States of America the two hundred and forty-eighth.</FP>

                    <P>
                        The rise of concentration and changes in contracting practices in livestock and poultry markets over the last four decades have facilitated and exposed producers and growers (hereafter, producers unless otherwise noted) to increasing economic harms from exclusionary, prejudicial, or otherwise discriminatory conduct, as well as deceptive conduct, by packers, swine contractors, and live poultry dealers (hereinafter regulated entities, unless otherwise noted). The regulatory toolkit embodied in the Packers and Stockyards Act, 1921, as amended (P&amp;S Act or the Act) (7 U.S.C. 181 
                        <E T="03">et seq.</E>
                        ), authorizes USDA to issue regulations to address these issues. This final rule seeks to address a discrete but important set of those wrongfully exclusionary or deceptive practices that undermine inclusive competition and market integrity: specifically, (1) discriminatory prejudices on certain bases relating to the producer's characteristics, (2) retaliation for engaging in certain acts as part of being a livestock or poultry producer or grower, and (3) false or misleading statements or material omissions in certain contexts. These practices deny producers opportunities to compete in the marketplace and earn the full value of their livestock sales or poultry growout services.

                         (87 FR 60010) a proposal to amend the regulations implementing the Act located in title 9, part 201, of the Code of Federal Regulations (CFR) by adding a new subpart O titled “Competition and Market Integrity.” AMS solicited comments on the proposed rule for an initial period of 60 days, and extended the comment period for an additional 45 days on November 30, 2022 (87 FR 73507). AMS received 446 comments from industry trade associations, non-profit organizations, individuals, State attorneys general, farm bureaus, academic/research institutions, and other groups. After consideration of all comments, AMS is adopting the proposed rule, with modifications designed to increase specificity and, therefore, certainty and enforceability.
                    </P>
                    <P>AMS is issuing these regulations to enhance basic protections that modern livestock and poultry producers need to promote inclusive competition and market integrity. Specifically, this final rule will:</P>
                    <P>• Prohibit, as undue prejudices or disadvantages, actions that inhibit market access or actions that are otherwise adverse to covered producers on the basis of race, color, religion, national origin (including ethnicity), sex (including sexual orientation and gender identity, as well as pregnancy), disability, marital status, or age; or because of the covered producer's status as a cooperative, with certain narrow exceptions such as the provision of religious meats and the functions of Tribal governments;</P>
                    <P>• Prohibit, as unjust discrimination, retaliatory and adverse actions that interfere with lawful communications, assertion of rights, associational participation, and other protected activities;</P>
                    <P>• Prohibit, as deceptive practices, regulated entities employing false or misleading statements or omissions of material information in contract formation, performance, and termination; and prohibit regulated entities from providing false or misleading representations regarding refusal to contract; and</P>
                    <P>• Require recordkeeping to support USDA monitoring, evaluation, and enforcement of compliance with aspects of this rule.</P>
                    <P>
                        AMS is adopting this final rule to promote inclusive competition and market integrity, as rational decision-making, so critical to economic success, can most effectively occur in a market free of the practices prohibited by this 
                        <PRTPAGE P="16093"/>
                        rule. This final rule also affirms the importance of a clear and direct regulatory framework with respect to prohibited conduct, thus protecting producers in the marketplace. This rule does not address every possible way in which producers may be wrongfully excluded or deceived under the Act. Producers who believe their rights under the Act have been violated—whether specifically under this final rule, or in other circumstances—can report a violation to AMS.

                         Producers may also enforce the law and its regulations through private rights of action under the Act. Penalties under the Act depend upon the nature of the particular violation, including the particular animal species, and range from monetary penalties to injunctive relief.

AMS has chosen this effective date because it believes that compliance with this final rule will not require significant administrative or financial obligations for regulated entities. The low cost, coupled with minimal process changes regulated entities will be required to make to comply, support an effective date 60 days after publication. Sixty days will provide adequate time for regulated entities to be informed of the specified conduct this final rule prohibits as well as make changes to comply with the final rule.

                    <HD SOURCE="HD2">A. Current Market Structure and Risks for Producers</HD>
                    <P>Market abuses of discrimination, retaliation, and deception can occur in livestock and poultry markets. Such conduct is amplified and exacerbated under increasingly concentrated livestock and poultry markets. Such markets are dominated by a few large packers and live poultry dealers. Additionally, changes in contracting practices, specifically bilateral contracting and vertical contracting that reaches farther into the production aspects of livestock and poultry, have given processors greater control over producers. These changes can exacerbate the impacts of discriminatory, retaliatory, and deceptive conduct by packers and live poultry dealers, which inhibits producers from fully participating in livestock and poultry markets or obtaining the full value of their livestock and poultry products and services. With few marketing options in concentrated markets, producers are more likely to suffer long lasting harm from market abuses by packers and live poultry dealers than would be the case in a marketplace that is more competitive.</P>
                    <P>
                        A review of the historical structure of livestock and poultry markets shows how the risk of worsened competitive conditions or materially adverse effects to producers at the hands of a few large processors (livestock packers and live poultry dealers) has grown over time. In the late 1800s to early 1900s, the “Big Five” 
                        <SU>3</SU>
                        <FTREF/>
                         large meat packers dominated the livestock market by working cooperatively to jointly set prices and divide territories amongst themselves.

                        <FTREF/>
                         In 1921, Congress enacted the Packers and Stockyards Act, 7 U.S.C. 181-229, to promote effective competition and integrity in livestock, meat, and poultry markets because it believed that the large packers employed anticompetitive or abusive practices that harmed producers and consumers.
                        <SU>6</SU>
                        <FTREF/>
                         The objective of the P&amp;S Act is “to assure fair trade practices in the livestock marketing . . . industry in order to safeguard farmers and ranchers against receiving less than the true market value of their livestock.” 
                        <SU>7</SU>
                        <FTREF/>
                         After the enactment of the P&amp;S Act, several decades of relatively more competitive conditions in the livestock markets prevailed; however, structural shifts in the industry defined by technological and productivity advances and mergers and acquisitions by meat processors led to fewer and larger meat processors—increased market concentration—in the latter half of the 20th century. This transformation led to much larger sized packing plants, multi-plant packers and live poultry dealers; raised barriers to entry; reduced the number of meat processor competitors; and reduced competition. Today, greater use of bilateral and vertical contracting in the livestock and poultry industries also gives regulated entities greater practical ability to cause these harms in ways that are hard for producers to avoid.

The HHIs in the table assume equal market share for each integrator and, as such, are the minimum HHIs possible (at least with 2 to 4 growers). They show that 88.4 percent of growers are facing an integrator HHI of at least 2,500. The data suggest that most contract broiler growers in the U.S. are thus in markets where the live poultry dealers have the potential to exercise market power.

                        One of the notable structural changes over the course of the 20th century was the improvement in refrigeration technology. Refrigeration enabled meat packers to move away from the from Great Lakes and the Upper Midwest, where they could source large quantities of ice and build facilities closer to the centers of livestock production.

                         Slaughterhouse and fabrication plants, therefore, could and did move away from urban areas to remote rural locations. As technology and the ability to scale operations also grew in the latter half of the 20th century, plants also grew in size.

                        These changes had two implications over time. First, as processing plants moved from urban to rural areas, producers were more vulnerable to an exercise of monopsony power because the local and regional markets became more concentrated.

                         Second, instead of terminal (auction) stockyards aggregating livestock for sales to packers, packers and producers increasingly entered into bilateral contractual relationships to buy livestock.

                        <FTREF/>
                         When producers utilized stockyards for their livestock sales, they could rely for protection on the provisions of title III under the Act, which established robust nondiscrimination protections for producers (in sec. 312), as well as a DOJ Consent Decree in 1920 with the major packers, which established that the stockyards had to be structurally separate from packers.

                         For example, in 1968 USDA issued a Statement of General Policy under the Packers and Stockyards Act to clarify that the prohibitions against unjust discrimination under sec. 312 governing “just and reasonable stockyard services” prohibited discrimination on the basis of race, religion, color, or national origin. However, as the industry structure evolved and livestock were increasingly sold through bilateral, vertical contracts, producers were no longer protected by sec. 312 of the Act. Instead, the sales were governed by title II of the Act, under which sec. 202(a) and (b) prohibits unjust discrimination and undue prejudice.

                             (Documenting the historic shift from terminal auctions, in which around 90 percent of livestock were marketed in the 1920s; to 75 percent in the 1940s; to just 7 percent by 1984 (Lauck 1998; Aduddell 1981). In terminal auctions, market participants, including producers, new independent packers, and retailers enjoyed the benefits of transparent pricing and many possible marketing channels. The number of terminal auctions doubled every decade from 1935-1955 (Aduddell 1981). In the latter half of the 20th century, a new generation of large packers located closer to producers; and built new facilities to process larger numbers of animals which they purchased directly from increasingly larger feedlots (Williams 1978). Various researchers during the time period documented how direct purchases from these packers accounted for a larger share of the industry's sales; and contributed to decreasing numbers of market transactions and bids in terminal markets. For example, for cattle, the number of single bid transactions for cattle increased by 64 percent from 1982 to 1987; and by 38 percent for hogs (Purcell 1990). In turn, producers facing fewer buyers often reported lower prices paid (Marion 1988).

                    <P>The broiler industry also grew quickly after the Second World War. Early on it adopted a production model in which live poultry dealers contracted with poultry growers to grow-out broilers, rather than a model of independent producers selling broilers on the open market. With most broiler growing contracts, the live poultry dealer provides the chicks, the feed, and veterinary services, while the grower provides labor, facilities, equipment, and energy necessary to turn the chicks into slaughter-ready birds. At first, live poultry dealers were often feed suppliers, but now most processors act as live poultry dealers. Overall, the reality is that live poultry dealers have extensive control over production through the contracting practices.</P>

                        Furthermore, it is important to acknowledge the impact of a consolidating farm production landscape overall. With the livestock and poultry farming sectors consolidating over the last several decades, the aggregate number of producers has declined significantly, even as total production is stable or growing. Many factors driving the loss of producers in the marketplace are the same factors underlying the market changes referenced above and include productivity growth wrought by scientific and technological advances, economies of scale, and transportation improvements. As shown in Figures 2 and 3 below, over the last 60 years, changes in animal production have corresponded to declines on the order of 
                        <PRTPAGE P="16098"/>
                        hundreds of thousands of producers in nearly every size class except the largest, which increased by only hundreds of producers.

                        In the figure above, the intensity of shading indicates the magnitude of decrease (left) or increase (right), with shading intensity scaled individually to each map panel. Generally, the number of cattle and hog operations for every size class except the largest decreased in many counties across the U.S., while the number of operations for the largest size class increased in only a few counties. Owing to the limitations of available county-level data, the above map for cattle operations include both feedlot and cow-calf operations, of which only the first sell directly to packers in most instances. Feedlots and packers tended to locate closer to producers in the latter half of the 20th century. As feedlots became larger and more concentrated, the number of farms with fed cattle sales declined. For example, McBride found that from 1978-1992, as the distribution of cattle feedlots became geographically tighter, the number of counties contributing to half of cattle sales decreased from 73 counties in 1978 to just 44 counties in 1992, with a fourth

                        of sales coming from 13 counties. The number of feedlots declined from approximately 175,155 in 23 states in 1970 to 27,000 feedlots in 2020, with half of all fed cattle from just 132 of them.

                    <P>Data from Figure 3 clearly indicate a shift in livestock and poultry raising to larger farms. This shift has occurred in concert with an increase in bilateral and vertical contracting. Bilateral and vertical contracting facilitate the conditions in which discrimination and retaliation are more likely to restrict market opportunities of producers and cause them to earn less than the full value of their animals. It is harder to discriminate in the aggregated market of the stockyard than through bilateral contracting regimes. When producers are locked into long-term agreements with a single buyer, it is easier for buyers to discriminate on prohibited bases or retaliate in response to protected activities because they exercise considerably more leverage over producers. Buyer-seller relationships are more fixed, providing much less flexibility for producers. Furthermore, with the number of farms declining in number, the economic harms of discrimination and retaliation are more likely to be permanent as being denied a long-term contract may lead to permanent exclusion from the market. Smaller farms in particular may be more likely to be permanent casualties of discriminatory or retaliatory behavior in a consolidated farm context as buyers gravitate toward larger suppliers to more easily satisfy their volume requirements. Discriminatory or retaliatory behavior is more likely to harm producers economically because it is much harder to find alternative buyers in a world with fewer, bigger farms and fewer, bigger packers and live poultry dealers. This rule is not directly addressing consolidation at the farm level or concentration at the processor level, but in providing more protections to producers from discriminatory and retaliatory conduct, it is helping to prevent market exclusion.</P>

                         This final rule addresses some of the ways that livestock and poultry markets unfairly exclude producers or otherwise limit their ability to obtain the full value of their animals. This final rule does not address all the factors contributing to market exclusion. However, it does address several practices that exclude producers and, in doing so, violate the Packers and Stockyards Act. AMS recognizes that creating inclusive and competitive markets with integrity requires multiple legal, regulatory, and programmatic strategies to mitigate the potential harmful effects of concentration and vertical contracting; build up alternatives through investments in regional meat and poultry processing; 
                        <SU>25</SU>

                         and protect the rights of producers to develop producer organizations that advance farmer welfare, rural prosperity, and quality food. Thus, this rulemaking is one key piece to AMS's strong commitment to mitigating the factors that restrict market access for livestock and poultry producers.

                        AMS finds that current regulations under the Act do not sufficiently address the many unduly prejudicial, unjustly discriminatory, and deceptive practices in the livestock and poultry industry. As discussed above, the combination of increased concentration and use of vertical contracts in livestock and poultry markets enhances regulated entities' ability to unjustly discriminate against or deceive market participants and effect significant harm upon 
                        <PRTPAGE P="16101"/>
                        producers. With bilateral contracts where one side has significant market power, regulated entities can target specific individuals, whether because of their personal characteristics (prejudice) or because of they have engaged in certain activities (retaliation). With market concentration, producers have limited options in the marketplace with which to avoid the harms. Vertical contracts where regulated entities have greater control over producers' operations also enable certain forms of discrimination, such as in the provision of inputs, as live poultry dealers particularly have heightened control and involvement in the growers' poultry operations. The provision of accurate and not misleading information also takes on heightened importance in these markets. In markets where producers are exiting, it is especially difficult for producers to reenter after being excluded, and the harms from exclusion are significant.

                         The prejudicing entity that pays a producer below market value for his or her cattle or hogs because the producer belongs to a protected class causes that producer to not receive the full economic value of his or her animals; this discrimination also prevents the market from reaching an optimal allocation of wages and labor, contributing to a deadweight loss for the economy at large.

                        As previously noted, this rule does not address every form of discrimination or prejudicial exclusion or disadvantage in the marketplace but focuses on providing clarity regarding certain specific discriminatory and prejudicial practices that AMS has identified in this final rule as essentially unjust, which offer no benefits to the competitive market or producers, and which undermine competition on the merits of the products and services that producers offer. Additionally, although the descriptive analyses set forth below do not address the prevalence or degree or prejudice for each and every prohibited basis, owing to the limitations of available data, AMS believes that leaving out any of the bases listed in this rule would be inappropriate. Not only would that be inconsistent with the Department's approach toward discrimination in other contexts, as repeatedly endorsed by Congress, but the resulting uncertainty could also open the door to those forms of discrimination in livestock, poultry, and related markets under the Act, which would be contrary to the purposes of this regulation and

                    <P>AMS (including its predecessor agencies) has received complaints over the years of discrimination against producers, in particular in the poultry industry, and especially on the basis of race. The Agency has not always been able to act on these complaints for a variety of reasons. The Agency also believes that some complaints may have been suppressed due to the risks of retaliation, which are discussed below. As highlighted below, comments to this rulemaking affirmed the prevalence and remaining challenge of discrimination on prohibited bases.</P>

                        Researchers have documented the history of discrimination against racial and ethnic minorities in agricultural markets. Multiple factors have contributed to the decline of non-white-owned farms, specifically to the decline of Black-owned farms, including the Homestead Act of 1862, the Morrill Land Grant Act of 1862, lack of legal protections for heirs' property, and limited access to capital through discriminatory lending practices.

                         For example, in the earlier part of the 20th century, the Federal government and agricultural landholders restricted land sales, engaged in predatory and fraudulent lending practices, and denied farm support programs to Black farmers and ranchers,

In the livestock sector, the results of historical prejudice and the risk of present-day prejudice are apparent when looking at data from the 2017 Census of Agriculture, which show that a small fraction of livestock farms with production contracts are operated by Black, Asian, American Indian, or Native Hawaiian producers (Figure 1).

                         In Figure 1, the checkered bars represent the share of racial and ethnic groups among all livestock and poultry farms, and the colored bars indicate the share of production contracts received by each group. As indicated in Figure 1, American Indian, Black, Native Hawaiian, and Hispanic producers receive less than a proportional share of livestock and poultry production contracts relative to their respective populations. For example, Black producers and growers account for 1.6 percent of U.S. farms by race and ethnicity and receive a disproportionately lower 0.5 percent of livestock and poultry contracts. White producers and growers, meanwhile, represent 91 percent of all farms, but 98 percent of hog contracts and 97 percent of cattle contracts—a greater than proportionate share of livestock contracts, and at 90 percent, a lower than proportionate share of poultry contracts. Non-white racial and ethnic groups constitute a very small share of contracted livestock and poultry producers, which can be attributed to limited access to land and capital,

                             Most production contracts are held by poultry growers and less so by packers. A production contract, according to USDA NASS, “is an agreement between a producer or grower and a contractor (integrator) setting terms, conditions, and fees to be paid by the contractor to the operation for the production of crops, livestock, or poultry.” In contrast, many packers hold marketing contracts which, according to NASS, are “based strictly on price.” USDA NASS, No Date. “Appendix B.

                        Disparities are also found in income across racial and ethnic groups. It is difficult to disentangle historical discrimination—whether that be prejudicial administration of USDA farm policies, racial segregation laws, or discriminatory private lending policies, from current discrimination practiced by livestock and poultry companies. Figure 5 shows the percentage of livestock and poultry farms (omitting nonfamily farms) by the reported race or ethnicity, and categorized by the lowest level of Gross Cash Farm Income (GCFI), which is annual income before expenses, including cash receipts, farm-related cash income, and government payments.

                         These data indicate that livestock and poultry farms with producers who identify as American Indian, Black, Native Hawaiian, and Hispanic are more likely to be in the lowest income category (measured by GCFI &lt;$150,999) than their white counterparts. Those farms with producers who identify as Asian are less likely than their White counterparts to fall into the lowest income group, which might be a factor of being relatively recent immigrants and not facing past discrimination.

                         The fact that Black, Native Hawaiian, Native American, and Hispanic livestock and poultry farmers are more likely to be in the lower income GFCI category could be an effect of past discrimination, and it also could make such producers more vulnerable to current discriminatory behavior by packers. Markets dominated by one or a few large packers or live poultry dealers may also be less accessible to these lower income farms, which have limited financial or other economic resources with which to engage.

                         suggests that certain ethnic or racial groups are receiving lower prices compared to White producers from regulated entities in livestock and poultry contracts. In some cases, the research showed statistically significant differences in prices received for livestock (cattle and hogs) and broiler products across ethnic or racial groups after controlling for variables such as farm size, region, type of marketing contract or channel, organic certification status, distance to closest packer, and size of closest packer. Specifically, Black and American Indian cattle producers, Black contract broiler producers, and Black and American Indian hog producers all received lower prices for their livestock products relative to White producers. However, the effect of many animal quality variables, such as weight per animal, dressing percentage, and yield grade, cannot be controlled for under this analysis because the data is not in the Census of Agriculture or other data sets organized by race and ethnicity. Thus, endowment differences, such as better land and more capital, that represent the legacy of historical discrimination may account for a portion of these price differentials.

                    <P>Differences in livestock and broiler prices could also be due, at least in part, to discrimination. Due to current data deficiencies, however, it is impossible to tell whether differences in prices received across ethnic or racial groups are due to current discriminatory practices, historic discrimination, or some combination thereof. These omitted variables may be correlated with race or ethnicity, and thus may account for a substantial portion of the price differentials. Additional data collection efforts may shed light on the role of omitted variables, such as animal size, thus helping to distinguish economic effects arising from current racial discrimination from disparate economic outcomes due to historical discrimination.</P>

                        Gender is also a basis of discrimination in livestock and poultry markets. According to the 2017 Census, livestock and poultry operations where principal operators are female received significantly lower market value for the livestock and poultry they sell. Female principal operators in livestock and poultry earned 53 cents per operation for every dollar earned by male principal operators per operation. By comparison, in the broader U.S. population, females earn 77 to 82 cents for every dollar earned by men in 2022.

                         Figure 6 shows that the difference in livestock and poultry sales by gender is about $117,000 less per operation for female principal operators, or 47 percent less, compared to male principal-operated farms. Disproportionately more female operators are found in the lower income classes relative to males, and a disproportionately higher number of male operators are found in the highest income classes. The value of livestock and poultry production per total acres owned by males and females is $0.22 per acre for males and $0.18 per acre for females, or $0.82 per acre for female operators relative to every $1 per acre earned by male operators. Together, these data suggest that female

Table 3 presents the empirical results of multivariate regression analysis of the 2017 Agricultural Census and other data by the USDA Office of the Chief Economist. Black and American Indian cattle and broiler producers, and Black and American Indian hog producers of owned hogs (hogs not sold under production contracts) all received lower prices for their livestock products relative to White producers. For example, Black and American Indian producers received around 5 percent lower broiler prices but no statistically significant decrease in payments for hogs delivered under production contracts. However, the effect of many animal quality variables, such as weight per animal, dressing percentage, and yield grade, cannot be controlled for under this analysis because the data is not in the Census of Agriculture or other data sets organized by race and ethnicity. Thus, endowment differences, such as better land and more capital, that represent the legacy of historical discrimination may account for a portion of these price differentials. Hawaiian contract hog producers received 68 percent higher prices even though producer location was controlled for in the analysis, but the analysis cannot control for some unknown factors associated with this relatively small cohort of producers that may account for this relatively large price effect.</P>

                        The results of an analysis presented in Table 3 found there is a statistically significant and positive relationship between female operators and price received for the owned-hog market, which includes producers of both contracted and owned hogs (the regression accounted for whether the producer was on a production contract or not through an explanatory variable), but which examines the price impact only on owned-hogs sold.

                         However, for the production contract-only hog market, which makes up about 70 percent of all hogs produced, this relationship becomes negative, though not at a statistically significant level (non-statistically significant results are shown as zero values in the table). From regression results not shown in Table 3, it appears that female contract hog producers who also produce owned hogs receive a higher price for owned hogs than female farmers who only produce owned hogs. This finding suggests that females with hog contracts face preferential prices relative to those females that do not hold contracts.

That is, as producers and growers age in the owned-hog and poultry markets and gain experience in the contract hog market, average price received declines. However, the same finding was not evident in cattle markets, where the relationship between increasing producer age and price is positive and statistically significant.</P>

                             For the purposes of this preamble, a cooperative is an incorporated or unincorporated association of producers, with or without capital stock, formed for mutual benefit of its members. Farm cooperatives are formed under State, not Federal law, even though cooperatives have Federal protections.

Although much of the law that has developed around cooperatives has developed with respect to agricultural cooperatives, cooperatives exist in many areas . . . including housing, insurance, banking, health care, and retail sales, among others.”). Cooperatives can both be buyers and sellers of agricultural products. Cooperatives made up of sellers, because they jointly fix the prices of their goods, are legally permitted to market the products they produce when the cooperative organization meets the requirements of the Capper-Volstead Act (see 7 U.S.C. 291)7 U.S.C. 291) or the Clayton Act (see 15 U.S.C. 17).15 U.S.C. 17).

                        Regulated entity resistance to producer cooperatives is not difficult to understand—and indeed has been the basis for congressional action in the past. The increased bargaining power that cooperatives give to their members makes them a target for opposition or curtailment by regulated entities. In a market characterized by concentration of larger market intermediaries, cooperatives

                         can assist producers in promoting equal access to the market

                        and enhance the bargaining power of smaller producers. At the same time, cooperatives are responsive to the needs of regulated entities and the market for greater volume, as opposed to negotiating with many smaller producers.

                         Yet precisely that presence of enhanced bargaining power, which cooperatives give to their members, makes them a target for opposition or curtailment by regulated entities. Congress has affirmed that cooperatives are necessary to protect the marketing and bargaining position of individual farmers and that interference with this right is not only contrary to the public interest but damaging to the free market.

                        Producers have indicated to AMS that increased use of cooperatives is necessary because of the rise of abusive conduct aggravated by concentration in the markets and the decline in marketing options for smaller producers. For example, small cattle producers have expressed their concern to AMS about packers' disparate treatment of large and small producers. Large packers have commonly shown limited interest in dealing with producers that operate on a smaller capacity. Packers often prefer to buy large numbers of animals at once to lower transaction costs,
                        <SU>60</SU>
                        <FTREF/>
                         and if a single producer is unable to meet such demand, that producer is unable to compete in the industry. Smaller livestock producers can join together through cooperatives to achieve scale and meet buyers' volume requirements. Thus, cooperatives can help smaller producers gain business they would otherwise be unable to compete for in light of the current market structure. Moreover, Congress has encouraged the formation of agricultural cooperatives and, under the AFPA, has provided enhanced protection for them in the marketplace. Given that policy and statutory judgment, AMS interprets the Act to reinforce that objective. Accordingly, discriminating against a cooperative, absent a legitimate basis set forth under this final rule, is unjust and violative of the Act.

                        Additionally, cooperatives counterbalance the ability of regulated entities to exert market power against smaller or more vulnerable producers. Facing the threat of such a counterbalance, regulated entities have over time stymied producers' ability to form and utilize cooperatives. AMS has heard numerous reports of regulated entities terminating growers' or producers' contracts for their attempts to form cooperatives, as well as reports of the chilling effect such action has on any future attempts to do so.

                         More recently, cooperatives in the cattle sector have been frustrated in their effort to negotiate collectively. In recent years, the number of livestock and poultry cooperatives has declined, as shown in the figure below. While many reasons for that decline are unconnected to the discrimination prohibited in this rule, AMS believes cooperatives serve a crucial function in the marketplace and need protection against unjust discrimination by regulated entities. This final rule will protect producers who wish to form cooperatives and will strengthen the marketing and bargaining position of smaller or more vulnerable producers by enabling them to pool resources, coordinate, compete more effectively, and negotiate for fair and appropriate terms in the open market without fear of prejudice or discrimination from larger market intermediaries.

                        Numerous public comments on the proposed rule supported the prohibition of undue prejudice based on protected bases such as those described above. In expressing support for the proposed “market vulnerable individual (MVI)” approach to addressing undue prejudices, several agricultural advocacy groups recommended that AMS explicitly enumerate protected bases in its definition of MVI. MVI, as defined in the proposed rule, is a person who is a member, or who a regulated entity perceives to be a member, of a group whose members have been subjected to, or are at heightened risk of, adverse treatment because of their identity as a member or perceived member of the group without regard to their individual qualities. The organizations said these protected bases should include, but not be limited to, the protected classes of race, color, national origin, religion, sex, sexual orientation, disability, age, income derived from a public assistance program, and political beliefs.

                         An agricultural advocacy group commented in support of a protected-bases approach, saying that “fair access to markets for growers, farmers, and ranchers should be based on their farming and business skills, not on their membership in any of the above groups.”

                    <P>
                        Many producers across all animal species have expressed concerns about being retaliated against for engaging in legitimate business and advocacy activities inextricably linked to livestock and poultry markets. Contract poultry growers and hog producers have expressed to USDA that they have experienced—and consistently fear—retaliation from live poultry dealers and packers for communicating with each other, with their dealer's and packer's competitors, and with governmental officials, as well as for forming associations and cooperatives, exercising contract or legal rights, or being a witness in proceedings against the regulated entity.

                         Cattle producers have similarly expressed fear that packers will refuse to offer bids on livestock, or purchase livestock from disfavored producers, and they have highlighted other, more subtle retaliatory behaviors, like delaying delivery or shipment, for engaging in similar activities.

                        <FTREF/>
                         Producers believe the ability to communicate with others, to form associations and cooperatives, to exercise legal rights, and to witness against regulated entities are critical to free participation in the livestock and poultry markets. Inhibition of these freedoms jeopardizes producers' ability to obtain the full value of their livestock and poultry products and services. Indeed, producers have reported to AMS over the years that retaliation by regulated entities—or threat thereof—for producers' exercise of these rights is significant enough to place a producer's entire farm at risk. This reported conduct is the type of behavior AMS aims to prohibit through this rulemaking.

                             numerous producers, including the previous president of the Kansas Cattlemen's Association, discussed instances in which they experienced retaliation from the largest packers. For example, one producer described how they decided to allow other packer buyers first opportunity to buy cattle in response to the packer not selecting them for a contracting agreement. The producer said that the packer told “his buyer to quit coming into our yard.” Another producer agreed, describing an incident in which they perceived that one of the largest packers possibly retaliating against them for previous litigation: the producer described how the packer hung a “No Trespassing” sign on the producer's door and began offering a “five-minute window” to buy cattle).

                        This is a persistent problem. As recently as April 2022, threats and fear of retaliation interfered with witness testimony at each of the House and Senate Agriculture Committees' hearings on livestock competition practices. In his opening remarks, House Agriculture Committee Chair David Scott noted, “We were supposed to have a 4th witness, a rancher, on our panel, but due to intimidation and threats to this person's livelihood, to this person's reputation, they chose not to participate out of fear.

                        In response to the proposed rule, commenters expressed support and opposition for the proposal to establish prohibitions against retaliatory practices. Several industry associations opposed the proposed rule, indicating it is duplicative and therefore not necessary. These commenters contended the conduct addressed in the 
                        <PRTPAGE P="16111"/>
                        proposed rule is not a widespread problem and is already prohibited under the Act. Other commenters supported the rule. One organization cited a recent anonymous survey of contract growers it had conducted. Multiple respondents had experienced retaliation from integrators and said integrators regularly terminate contracts with farmers who engage in whistleblowing activities. These contract terminations leave growers with substantial debt tied up in specialized, single-use structures built as a condition of their contractual agreements. Although comments in response to the proposed rule differ greatly regarding the need for this rule, commenters generally do not disagree that discriminatory and retaliatory conduct is harmful to producers and offers no procompetitive benefits. For these reasons, AMS needs to use its statutory authority to provide a regulatory framework for prohibiting retaliatory behavior by regulated entities against covered producers. Establishing regulatory protections to prohibit regulated entities from retaliating against producers engaging in lawful activity will help promote fair trade practices and competitive markets.
                    </P>
                    <P>In recent years, producers have been increasingly vulnerable to harms from retaliatory behavior due to the market power afforded regulated entities under contracts that can reach further down into livestock and poultry production and/or are bilateral. This is in contrast to past circumstances where these relationships were intermediated through an institution such as a stockyard (auction) subject to heightened regulatory duties around nondiscrimination.</P>
                    <P>
                        As regulated entities have obtained greater control over the input industries, particularly in poultry, producers are increasingly dependent upon regulated entities for success. That dependence, in combination with high levels of debt, leaves producers vulnerable to the retaliation that regulated entities can exact through input distribution and in other ways. Growers have for years reported punitive delivery of inputs to deter their exercise of a wide range of legal rights and remedies that would enable them to earn the full value of their services.

                             1, 237-260 (Researchers have documented the increased incidence of producers' complaints and decreasing satisfaction in the industry beginning in the 1980s, which coincided with increasing concentration of the industry. Weinberg writes how, in 1960, 19 firms processed 30 percent of total US poultry processed and that producers who entered the business tended to achieve upward mobility. In the 1970s, only 8 firms processed the same percent of poultry. This trend accompanied an increased incidence of grower dissatisfaction. Gordy notes how “loss of independence and lower incomes caused some growers to become disenchanted.” Fite observed how poultry farmers were “controlled and sometimes exploited by their suppliers.” Peck notes how dissatisfaction by growers prompted State attorneys general to propose a 3-day right of review in a model producer protection act in the early 2000s. In 2010, the USDA and DOJ hosted a series of workshops in which growers raised concerns about retaliation in the industry. These trends, which occurred alongside increased productivity gains and use of technology, coincided with exits in the industry. As Weinberg documented, in Georgia, in 1950, 1176 Hall County farms sold 6.8 million chickens; in 1992, only 192 sold 44.3 million chickens).

                        Based on complaints and industry experience, AMS is aware that retaliation by regulated entities may take many forms, such as canceling contracts, selectively enforcing contract terms, refusing to deal or negotiate, or otherwise impairing an individual's or group of producers' ability to operate.

                         In contrast, in more competitive markets, producers facing retaliation can more easily avoid or mitigate adverse impacts by simply finding other entities with whom to do business. Without choices, producers are at the mercy of the types of abuses the Act was designed to prevent—market abuses that inhibit producers' ability to get the full value of their products and services. Ultimately, regulated entities may retaliate for various reasons, but none have any role in or benefit to the competitive functioning of the market.

                        The Packers and Stockyards Act has long recognized that integrity and honesty are vital to the marketing of livestock and, therefore, to the efficiency with which these markets supply meat to the American consumer.

                         This rulemaking is a response, in part, to the range of complaints lodged with USDA, Congress, and the media over the years regarding inaccurate, incomplete, or otherwise false or misleading statements, or omission of material information that affects decision-making or access to markets by producers. These complaints reflect, in part, changed industry contracting norms or a market environment where the prevalent norms result in more acute harms to producers. For example, packers and industry representatives have routinely indicated that producers may choose the form of pricing mechanism for their transactions. However, as cash-negotiated markets have declined, producers have increasingly complained to USDA that they are not provided such a choice, and are commonly given a take-it-or-leave-it offer to buy their cattle off of a pricing formula provided by the company.

                         Producers have complained they have been told that packers refuse to buy their cattle on the grounds they are not of sufficiently high quality or that formula market arrangements are necessary to incentivize such quality, when the cattle being offered were of no less quality than those the packer procured under other marketing arrangements.

                        Poultry producers have complained to USDA over the years regarding unfavorable provision of inputs made to certain producers despite statements by live poultry dealers that there are no differences in treatment. Producers have also complained to USDA of terminations, suspensions, or reductions in flocks on pretexts—

                         Contract termination puts the grower at severe risk of significant economic loss. A production broiler house often has significant long-term financial obligations. The potential loss includes not only the loss of production income, but financing for construction, which often comes from mortgages on the grower's farm or family home. Pretextual cancellation may make even the sale or transfer of the broiler production house impossible because purchasers may be unable to determine whether the broiler houses have value.

                    <P>Section 407 of the Act provides that the Secretary “may make such rules, regulations, and orders as may be necessary to carry out the provisions of this [Act].” (7 U.S.C. 228(a)) The Secretary has delegated the responsibility for administering the Act to AMS. Within AMS, the Packers and Stockyards Division (PSD) of the Fair-Trade Practices Program has responsibility for the day-to-day administration of the Act. The current regulations implementing the Act are found in title 9, part 201, of the CFR.

Accordingly, this final rule addresses the unfair treatment of farmers and improves competitive conditions in markets. This rule adds clarity to USDA's regulations concerning unjustly discriminatory practices, deceptive practices, and undue or unreasonable prejudices or disadvantages. E.O. 14036 underscored that “it is unnecessary under the... Act to demonstrate industry-wide harm to establish a violation of the Act and that the `unfair, unjustly discriminatory, or deceptive' treatment of one farmer” violates the Act. Among other policy goals in the E.O., this final rule is specifically intended to address the unfair treatment of farmers and make it easier for them to garner the full value of their animals. The Act is a remedial statute enacted to address problems faced by farmers, producers, and other participants in the markets for livestock, meats, meat food products, livestock products in unmanufactured form, poultry, and live poultry; to protect the public from predatory practices; and to help ensure a stable food supply. Thus, as academics and courts have noted, the Act has “tort-like provisions that are concerned with unfair practices and discrimination” that fulfill a “market facilitating function,” which Congress designed to prevent “market abuse.”

                    <HD SOURCE="HD1">IV. Summary of the Proposed Rule</HD>
                    <P>
                        In the October 2022 proposal, AMS proposed amending 9 CFR 201 by adding a new subpart O, titled “Competition and Market Integrity,” and containing §§ 201.300 through 201.390. AMS proposed adding a Definitions section, § 201.302, containing the terms 
                        <E T="03">covered producer, livestock producer, market vulnerable individual,</E>
                         and 
                        <E T="03">regulated entity.</E>
                    </P>
                    <P>AMS also proposed adding § 201.304, titled “Undue prejudices or disadvantages and unjust discriminatory practices,” to prohibit regulated entities from discriminating against a market vulnerable individual or a cooperative, detailing in proposed paragraph (a) types of prohibited actions. Paragraph (b) of the proposed regulation would prohibit regulated entities from retaliating against a covered producer because of the covered producer's participation in a producer association, protected activities, including assertion of rights under the Act, and lawful communication. Proposed paragraph (b) also provided examples of prohibited retaliatory actions. Proposed paragraph (c) included a requirement that regulated entities retain records of compliance with paragraphs (a) and (b) for no less than five years from the date of record creation.</P>
                    <P>
                        AMS also proposed adding § 201.306, titled “Deceptive practices,” prohibiting a regulated entity from employing a false or misleading statement or omission of material information necessary to make a statement not false or misleading during contract formation, 
                        <PRTPAGE P="16113"/>
                        performance, and termination. Section 201.306 also proposed to prohibit a regulated entity from providing false or misleading information concerning a refusal to contract. The proposal was designed to prohibit regulated entities from specified deceptive practices in contracting, which are of particular concern because of the power of the regulated entities over their vertical contracting relationships. As stated in the proposal, AMS intended this proposed regulation to address broad areas of specific concern, not exhaustively identify all deceptive practices that would violate sec. 202(a) of the Act.
                    </P>
                    <P>Finally, AMS proposed adding § 201.390, titled “Severability.” This provision was intended to inform reviewing courts that if any provision of subpart O was declared invalid, or if the applicability of any of its provisions, or any components of any provisions, to any person or circumstances was held invalid, the validity of the remaining provisions of subpart O or their applicability to other persons or circumstances would not be affected. Severability provisions are typical in modern AMS regulations. AMS regulations often cover several different topics in a subpart. This provision was added because the regulations in subpart O are designed to address several different types of violations under the Act. Because these violations address similar underlying developments in the livestock and poultry markets—namely, abusive practices facilitated by increased vertical integration and horizontal concentration—these violations were suitable for joining in a single rulemaking. However, each could be viewed as its own stand-alone rulemaking and therefore should be severable.</P>
                    <P>Upon consideration of public comments on the proposed rule, AMS modified some of its proposed provisions to derive this final rule. These changes are outlined below.</P>
                    <HD SOURCE="HD1">V. Changes From the Proposed Rule</HD>
                    <P>AMS is making the following changes to the proposed rule based on the agency's analysis of the issues raised by commenters.</P>
                    <HD SOURCE="HD2">A. Market Vulnerable Individual (MVI) to Prohibited Bases</HD>
                    <P>
                        With respect to the proposed regulations regarding undue prejudice and unjust discrimination, § 201.304, several commenters expressed concern that the definition of “market vulnerable individual (MVI)” as the basis for prohibiting undue prejudice and discrimination was too broad and ambiguous and could lead to an avalanche of litigation. To simplify this section, the final rule uses a delineated set of protected bases against undue prejudice and discrimination that were discussed in the proposed rule: race, color, national origin, religion, sex, sexual orientation, gender identity, age, disability, and marital status. These delineated bases reflect the Statement of General Policy Under the Packers and Stockyards Act published by USDA in 1968 (9 CFR 203.12(f)) and USDA's Conducted Programs Statement, and reflect a general congressional policy as indicated in other statutory sources (discussed below).

                        <FTREF/>
                         The final rule retains status as a cooperative as a protected basis against undue prejudice and discrimination, which reflects the principles set forth in the Agricultural Fair Practices Act of 1967.

                         (For the avoidance of doubt, AMS notes that discrimination against a member of a cooperative is prohibited under the provisions of paragraph (b)(2)(iii).) Accordingly, AMS has removed the term

                         from the list of terms defined for subpart O in § 201.302.

                    <P>AMS is adopting the aforementioned specific bases, as opposed to MVI, because the specific prohibited bases offer clearer, more workable standards to achieve the same goal set forth and specifically articulated in the proposed rule, but in a manner that will facilitate compliance by regulated entities and better enable producers to exercise their rights under the Act. As AMS explained in the proposed rule, the principal purpose of the MVI approach was to address prejudices in the marketplace against producers that are more vulnerable to such treatment and to stop unjust discrimination. AMS views vulnerability to adverse marketplace treatment to include, but not be limited to, exclusion or disadvantage on the basis of race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, marital status, or age, or on the basis of the covered producer's status as a cooperative. AMS initially adopted the MVI approach because it believed that the proposed rule's flexible approach to resolving marketplace vulnerabilities offered producers protection in an ever-evolving market. The proposed approach had the advantage of being responsive to the particular facts of given cases and particular markets over time.</P>
                    <P>As part of the rulemaking process, however, AMS sought comment on whether this was the best approach. AMS requested comment on whether it should “delineate specific categories of vulnerable producers on the basis of membership in groups that have historically been subject to adverse treatment owing to racial, ethnic, gender, or religious prejudices.” (87 FR 60010, Oct. 3, 2022) AMS also sought comment on “whether this regulation should ban discrimination against specific classes, such as on the basis of race, color, national origin, religion, sex, sexual orientation, gender identity, age, disability, marital status, or family status. Such an approach would differ from the market vulnerable individual approach and would instead more closely follow the civil rights laws that prohibit prejudicial discrimination against certain protected classes.”</P>
                    <P>
                        After considering the comments on both the MVI approach and on specific delineated bases, AMS determined that MVI is not sufficiently clear enough to meet the objectives of this regulation. The enumeration of specific prohibited bases provides more clarity and certainty by limiting the scope of the rule to prohibited adverse actions against all producers on the basis of their membership of a protected class, in line with existing civil rights requirements. Commenters, such as a meat industry trade association, a poultry industry trade association, and a live poultry dealer, criticized the proposed rule's MVI definition for being vague and ambiguous and potentially exposing their businesses to an unworkable standard that could potentially encompass a wide range of covered producers far beyond what the Agency appeared to be contemplating in the proposed rule. In contrast, these commenters indicated that an approach based on specific classes, such as race, sex, sexual orientation, or religion, would be clearer and would follow the precedent of civil rights laws already in place while protecting all producers.

                    <P>Multiple agricultural advocacy organizations also expressed approval of these protected classes as the prohibited bases for discrimination when responding to the proposed rule's solicitation of responses on this issue, saying discrimination against individuals in these groups should be clearly recognized so those individuals do not have to continually prove discrimination and prejudice against them based on the characteristic that makes them vulnerable in the market. AMS agrees that the bases adopted in the final rule reflect genuine vulnerability to market exclusion and have no competitive benefit.</P>
                    <P>AMS also notes that some commenters interpreted the MVI approach as potentially providing protection to small producers on the basis that small producers were vulnerable to discrimination in the form of the same kinds of adverse treatment proposed to be prohibited in this rule. While AMS is sympathetic to the plight of small producers' challenges in accessing fair markets, AMS did not intend this rule to address those concerns (as also discussed below in Section VII—Comment Analysis). Basing the rule on a term that gave rise to such disparate interpretations underlined the necessity of utilizing the more specific bases set forth in the proposed rule's alternative formulation.</P>
                    <P>
                        Additionally, AMS notes that these prohibited bases are now widely accepted standards of non-discrimination at USDA and in the U.S. economy more broadly. AMS adopted many of these as part of its 1968 Statement of General Policy.
                        <SU>93</SU>
                        <FTREF/>
                         Together with the Agricultural Fair Practices Act of 1967, these bases also apply to AMS enforcement of the Equal Credit Opportunity Act (ECOA) under the Act, to USDA programs through its Conducted Programs Statement, and, more recently, to the terms of USDA's debt relief under section 22007 of the Inflation Reduction Act.

                         The prohibited bases defined in the final rule have become so widely accepted as prohibited bases of discrimination that it would be notable and arbitrary for the Agency to pick some of the terms and not others. Quite simply, “

                    <HD SOURCE="HD2">B. Prohibited Actions Taken on a Prejudicial Basis</HD>
                    <P>
                        In § 201.304(a)(2), AMS made three changes to the provisions regarding prohibited actions taken on a prejudicial basis. First, in paragraphs (a)(2)(i) through (iii), AMS proposed to prohibit offering contracts that are less favorable than those generally or ordinarily offered, refusing to deal, and differential contract performance or enforcement, when each occurred on a prohibited basis. AMS is revising each of these provisions to provide clarity and uniformity across this final rule with respect to a comparison to similarly situated producers and also to ensure parallel language with the retaliation adverse actions under § 201.304(b)(3). Paragraph (a)(2)(i) is revised to read “Offering contract terms that are less favorable than those generally or ordinarily offered to similarly situated producers; paragraph (a)(2)(ii) is revised to read “Refusing to deal with a covered producer on terms generally or ordinarily offered to similarly situated covered producers”; and paragraph (a)(2)(iii) in the final rule is revised to read “performing under or enforcing a contract differently 
                        <E T="03">than with similarly situated covered producers</E>
                        ” [emphasis added]. “Similarly situated,” is a phrase commonly used by commenters and by AMS in the proposed rule when discussing producer groups.
                        <SU>96</SU>
                        <FTREF/>
                         Including this concept in the final regulation provides more context for a comparison of what differential performance or enforcement would look like, and therefore provides more specificity to the regulation. This revision also mirrors a revision made to language in a similar provision in the retaliation section (§ 201.304(b)(3)(ii) and (iv)). The addition of “with a covered producer” in paragraph (a)(2)(ii)—Refusal to deal, is similarly designed to align with the parallel provision for paragraph (b)(3)(iv) as was set out in the proposed rule and retained in the final rule. The final rule adds “on terms generally or ordinarily offered to similarly situated producers” as well, in response to comments (as discussed below) to provide similar clarity of application that refusal to deal is not simply an absolute boycott or making a sham or nominal offer, but includes failure to bid, negotiate, and otherwise make a reasonable attempt to contract on terms generally or ordinarily offered to similarly situated producers

                    <P>
                        Second, AMS is adding a new paragraph (a)(2)(iv), which prohibits—when it occurs on a prohibited basis—“requiring a contract modification or renewal on terms less favorable than similarly situated covered producers.” 
                        <SU>97</SU>
                        <FTREF/>
                         The new provision expands on the concept encompassed in paragraph (a)(2)(i), which prohibits “offering contract terms that are less favorable than those generally or ordinarily offered to similarly situated covered producers.” The new provision prohibits regulated entities from making contract terms less favorable for producers once they are under contract and have incurred financial obligations because of that contract. The new provision mirrors a new provision 
                        <PRTPAGE P="16115"/>
                        added to the retaliation section (§ 201.304(b)(3)(iii)) in response to public comment on the proposed retaliation regulations. AMS also uses a similar approach in the retaliation section on refusing to deal (§ 201.304(b)(3)(iv)), as requested by public commenters, by adding “with a covered producer on terms generally or ordinarily offered to similarly situated covered producers” after “deal,” for the same reasons—this language helps prevent evasion. Commenters requested that AMS provide more protection so that regulated entities cannot formulate new ways of harming producers in contracting—a crucial component of a producer's financial well-being. Commenters suggested an additional provision regarding specific contract terms, including contract modification, be added to the regulations. While AMS did not adopt the suggested provision in whole, AMS recognizes the importance of specifically prohibiting unfavorable contract modifications or renewals that occur on a prohibited basis, considering the detrimental financial impact this can have on producers already under contract. In making these changes, the final rule provides a greater degree of specificity regarding the type of conduct the rule prohibits. AMS will review the facts and circumstances of each case and the regulated entity's justifications for any modification or renewal to determine whether the regulated entity has violated this rule.

                        <P>
                            <SU>97</SU>
                             Proposed paragraph (a)(2)(iv), which prohibited termination or non-renewal of a contract on a prohibited basis, is renumbered in the final rule as paragraph (a)(2)(v).
                        </P>
                    </FTNT>
                      
                    <P>Third, AMS is adding a new paragraph (a)(2)(vi), which prohibits regulated entities from taking “any other action that a reasonable covered producer would find materially adverse.” This provision represents a logical outgrowth from the proposed rule, which had indicated that the “prejudice or disadvantage with respect to paragraph (a)(1) of this section includes the following actions.” As AMS explained in the proposed rule, AMS believes that the type of harm to a producer will not be difficult to identify when it occurs based upon the facts and circumstances, and thus provided an exemplary list to aid in identification and enforcement under the rule. Such a list was not intended to be all encompassing. However, in response to comments, AMS has recognized that such an open-ended approach may create too much uncertainty and undermine compliance and enforcement. AMS is replacing the use of “includes” with an additional, more flexible provision that provides a broader yet not unlimited range of possible harms. AMS's approach is in response to comments that adverse treatment of producers by regulated entities can occur outside the confines of the contractual relationship. Such conduct could include, for example, interference by a regulated entity into regulatory matters of significant material importance to producers. Several public commenters wanted more producer protections incorporated into § 201.304(a)(2). This provision provides a broad and flexible approach to these prohibitions and allows for “material” to be determined by the facts and circumstances of each case while staying within the scope of the proposed rule's intent around harms to producers under unjust discrimination and undue prejudice deriving from adverse actions.</P>
                    <HD SOURCE="HD2">C. Exceptions to the Prohibited Bases</HD>
                    <P>Commenters suggested that AMS include exceptions to the prohibition on undue prejudice and unjust discrimination. In response to these comments and the shift from MVI to identifying specific prohibited bases, AMS decided to provide specific exceptions from the prohibition in two circumstances. New § 201.304(a)(3) states that the following actions by a regulated entity do not prejudice, disadvantage, inhibit market access, or constitute adverse action under § 201.304(a)(1): (i) fulfilling a religious commitment relating to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry; (ii) a Federally-recognized Tribe, including its wholly or majority-owned entities, corporations, or Tribal organizations, performing its Tribal governmental functions.</P>
                    <P>In shifting from MVI toward specific prohibited bases, AMS identified the need to provide certain exceptions from the prohibition. The proposed MVI was a flexible standard that permitted the Agency to evaluate the facts and circumstances of a particular case and whether the exclusion or disadvantageous contracting arrangement was based on the characteristics of the producer. Specifying delineated prohibited bases provides greater clarity, yet in doing so, it eliminates a degree of flexibility that could be valuable in a small set of circumstances. Accordingly, the Agency is adopting two specific exceptions to recognize circumstances that do not give rise to unjust discrimination. AMS asked questions about both areas in the proposed rule, highlighting to commenters that the Agency recognized the potential for additional adjustments to be made in those areas.</P>
                    <P>
                        First, AMS is providing a specific exception to recognize the important role ritual slaughter plays in certain religious traditions and ensure that religiously significant meats—such as kosher, halal, and Amish meats—are not impacted by the rule's prohibition on discrimination on the basis of the producer's religion. According to AMS subject matter experts, halal slaughterers, for example, express a legitimate, religiously grounded preference for livestock and poultry raised by operators of faith, 
                        <E T="03">e.g.,</E>
                         the Muslim or the Amish Christian group, that maintain particular animal husbandry practices. In adopting its prohibition on prejudice on the basis of religion, AMS is principally focused on access to the broad livestock markets for persons where religion has no legitimate business purpose. In contrast, where religion is relevant to the livestock and meat itself, AMS is not seeking to disturb the religiously based determinations in what is a relatively discrete market segment. Therefore, when administering the Act, AMS must allow discriminatory conduct directed toward fulfilling religious commitments surrounding livestock care and meat production.
                    </P>
                    <P>To ensure clarity in its application, this rule respects longstanding jurisprudence surrounding Tribal sovereignty and the political relationship that a Tribe has with its members that secures the right for Tribal entities to preference Tribal members. To ensure that it is not read in contradiction with existing jurisprudence, the rule explicitly specifies that Tribal governments can engage in practices related to livestock, poultry, and meats with respect to non-Tribal entities or non-Tribal descendants. The prohibition on discrimination on the basis of race or color would be read to protect a person from discrimination for being of Native American descent, but not on preferential treatment given to Tribal members based on their political classification. This matter was specifically raised by, and is responsive to, Tribal governments during the Tribal consultation that AMS conducted and is described below under “VII.C.—Executive Order 13175—Consultation and Coordination with Indian Tribal Governments.”</P>
                    <P>
                        AMS recognizes that this rulemaking cannot foresee the range of unique or extenuating circumstances that may present in agricultural markets. Commenters stated that rapidly changing livestock and poultry markets may require an exception to the prohibition against undue prejudice or disadvantage on a protected basis. However, AMS did not identify, from the comments or based on its 
                        <PRTPAGE P="16116"/>
                        experience, any other specific circumstances in the livestock and poultry industries where a prejudice against a producer on a prohibited basis was justified under the Act. To the extent that unforeseen circumstances could arise that would justify creating the need to allow for additional exceptions to this rule, AMS believes that those circumstances are likely to be rare and tailored to narrow circumstances. Accordingly, AMS believes that prosecutorial discretion will provide it with adequate flexibility to offer relief on a case-by-case basis. Of course, if following implementation of this rule it becomes evident that additional exceptions should exist in regulation, AMS may amend this regulation through the ordinary rulemaking process.

                    <P>AMS proposed in § 201.304(b)(1) to prohibit retaliation against a covered producer that occurs because of the covered producer's participation in protected activities “to the extent that these activities are not otherwise prohibited by Federal or state law, including antitrust laws.” In the final rule, AMS modified the language of this provision to move the exception for Federal or State law, including antitrust laws, to paragraph (b)(2) and to add Tribal law to the types of law identified in this exception. AMS is adding this language to make explicit the applicability of Tribal law in this circumstance. Additionally, AMS changed “because of” to “based upon” both in response to comments and to align with its approach in § 201.304(a) and embodied in § 201.304(c). AMS proposed “based upon” in § 201.304(a) and “by employing” in § 201.304(c) to capture actions where the prohibited bases form a material part of the action—discrimination or prejudice, or as part of the deceptive practice. Section 201.304(b) is designed to achieve the same goal. AMS also received comments recommending broad protections for covered producers from retaliatory actions, including where the retaliation was a part of the decision to take an adverse action. AMS further underscores that “based upon the covered producer's participation in an activity . . .” covers threats that would reasonably dissuade or chill a covered producer from participating in the activities.  </P>
                    <P>Under proposed § 201.304(b)(2)(i), AMS proposed to establish as a protected activity a producer's communication with a government agency on matters related to livestock, meats, or live poultry or petitions for redress of grievances before a court, legislature, or government agency. Commenters requested that AMS clarify that this protection covers communication with any sector or level of government, including State governments. AMS intends for this regulation to include protections for communications with any level of government, including any government committee or official. In this final rule, AMS is aligning the use of the terms “court, legislature, or government agency” and simplifying the language to say, “government entity or official.” This change ensures that protected communications may occur with any of the three branches of government, any level of government, and with individual government officials, including committees and members of a legislature.</P>
                    <P>AMS requested public comment on whether the final rule should protect producers who choose not to participate in protected activities. In response to public comment supporting this proposal, AMS has revised § 201.304(b)(2)(ii) to protect a producer's right to refuse a regulated entity's request to engage in communication with a government entity or official that is not required by law, and § 201.304(b)(2)(iii) to protect a producer's right to form or join, or to refuse to form or join, a producer or grower association or organization. Proposed § 201.304(b)(2)(ii), which protected a producer's assertion of any of the rights granted under the Act or this part, or assertion of contract rights, is renumbered as paragraph (b)(2)(vii) in the final rule.</P>
                    <P>
                        AMS proposed in § 201.304(b)(2)(v) to protect producer communication or negotiation with a regulated entity for the purpose of exploring a business relationship. In response to public comment, AMS added in the final rule protection for communicating; negotiating; or contracting with a regulated entity, another covered producer, or with a commercial entity or consultant; for the purposes of exploring or entering into a business relationship. Commenters asserted that, as proposed, the protected activity was “unreasonably narrow” and that expanding this protection would “help ensure that covered producers may 
                        <E T="03">explore</E>
                         all their business opportunities.”

                         The Act is intended to ensure an inclusive market to protect and promote the ability for covered producers to compete.

                        <FTREF/>
                         Such competition may also take the form of exploring or entering into opportunities for enhanced price discovery through market intermediaries, such as listing cattle for competitive bidding on a publicly transparent exchange or selling at an auction barn or through a cooperative or other commercial entity that facilitates the marketing of livestock by the covered producer. The provision covers both the ability to negotiate or contract with the commercial entity or consultant serving as an intermediary or other facilitating the marketing or platform for marketing, such as the exchange or auction barn; and also the ability to negotiate or contract with other packers during the exchange or auction process. This is protected because both elements may be necessary parts of securing those opportunities to engage in price discovery and enhance the choice and competitive opportunities for covered producers to earn the full market value of their goods and services. The provision also covers consideration of alternative uses for farm property. As with all protected activities under this final rule, the regulated entity may not present an obstacle to engaging in these activities, whether written in a contract, verbally asserted, or otherwise, as those are impermissible under the Act.

                        Under proposed § 201.304(b)(3), AMS identified types of prohibited retaliatory conduct. Commenters expressed concern regarding the lack of clarity of these proposed prohibitions, with some saying the prohibitions were too broad, some arguing that the rule should provide even more flexibility, and some supporting the introduction of a “catch-all clause” to provide additional protection against retaliatory behavior. The final rule adds language to paragraph (b)(3)(ii) to prohibit performing under or enforcing a contract differently than with 
                        <E T="03">similarly situated producers</E>
                         [emphasis added]. This language, “similarly situated,” was commonly used by commenters and AMS in the proposed rule when discussing producer groups. The addition of “similarly situated” language provides greater specificity regarding the scope of the regulation by providing more context for a comparison of what differential 
                        <PRTPAGE P="16117"/>
                        performance or enforcement would look like.
                    </P>
                    <P>The final rule also revises the provision prohibiting a regulated entity from refusing to deal with a covered producer by adding the language, “on terms generally or ordinarily offered to similarly situated covered producers” (paragraph (b)(3)(iv) in the final rule). In response to comments, AMS agrees that the rule as proposed provided too great a latitude for a regulated entity to engage in retaliation because a regulated entity could, for example, satisfy the proposed rule by simply offering highly unfavorable terms to the covered producer. AMS believes that this revision provides broader coverage regarding the most common circumstances that producers may encounter in their business dealings in which regulated entities may attempt to exact retaliation. It would also cover circumstances where the “similarly situated producer” was the covered producer's own prior status quo circumstance with the regulated entity before the covered producer engaged in the protected activity. AMS is also aligning refusal to deal under paragraph (a)(2)(ii) to address the similar risk of evasion.</P>
                    <P>
                        Similarly, commenters requested that AMS add a regulation regarding contract modification, or contract renewal. AMS has amended proposed § 201.304(b)(3) to add a new paragraph (b)(3)(iii) to clarify that requiring a contract modification or a renewal on terms less favorable than for similarly situated producers is covered.

                        <FTREF/>
                         This provision covers any adverse change to the covered producer's contract terms if they are done in retaliation to a producer's engaging in protected activities. Additionally, in response to comments requesting AMS clarify that prohibited adverse actions “includes but is not limited to” the list in proposed § 201.304(b)(3), AMS has added a new paragraph (b)(3)(vi) to prohibit “any other action that a reasonable covered producer would find materially adverse.” AMS designed this rule to protect producers broadly from adverse actions based upon the rule's prohibitions. The regulatory text of the proposed rule set forth an exemplary list, specifically denoting that “retaliation includes the following actions” (paragraph (b)(2). Several public commenters wanted more producer protections, such as discriminatory conduct against producers by regulated entities through means outside of contractual devices. AMS agrees that adverse, retaliatory treatment of producers by regulated entities can occur through a wide range of means, including outside the confines of contractual devices, or through contractual means that are not easily delineated in a specific list. Such conduct could, for example, include interference by a regulated entity into regulatory matters of significant material importance to producers. Based on AMS's regulatory experience, regulated entities may interfere in covered producers' water rights, which are exemplary of harms that would be considered retaliation even if they occur outside the confines of contractual relationships. Or, conduct could include retaliation during the contracting process for protected activities that occurred prior to the covered producer's attempt to form a business relationship with the regulated entity. Such examples might not be clearly covered under §§ 201.304(b)(3)(i) through (v) of the proposed rule's protections relating to contracts but were covered within the scope of the proposed rule's intent around broad-ranging adverse actions that harm producers. AMS also intends the list of retaliatory activities to be broad enough to capture the fullest range of materially adverse harms encompassed under unjust discrimination and undue prejudice—including in comparison to either their prior circumstances or to similarly situated producers—and threats of such harms that are designed to deter or punish producers from participating in the activities protected by this final rule. Therefore, § 201.304 (b)(3)(vi) has been added to the final rule to cover other types of adverse treatment. This provision provides a broad and flexible approach to these prohibitions and allows for “material” to be determined by the facts and circumstances of each case.

                    <P>In making these changes, the final rule provides a greater degree of specificity regarding the type of conduct the rule prohibits. AMS is not, however, providing the degree of specificity requested by commenters regarding unfavorable contract terms because it is impractical to name every action a malicious actor could use to retaliate against a producer, and providing this level of detail is not necessary to enforce the rule.</P>
                    <HD SOURCE="HD2">E. Technical Changes</HD>
                    <P>
                        AMS made editorial changes to the text of several proposed regulations to improve clarity and readability. For instance, in the definition of 
                        <E T="03">livestock producer,</E>
                         AMS revised the proposed definition by removing multiple prepositions, so that the definition in the final rule reads more simply: from “
                        <E T="03">Livestock producer</E>
                         means any person engaged in the raising and caring for livestock by the producer or another person, whether the livestock is owned by the producer or by another person, but not an employee of the owner of the livestock” to “
                        <E T="03">Livestock producer</E>
                         means any person, except an employee of the livestock owner, engaged in the raising of and caring for livestock.” Additionally, AMS revised the syntax of several proposed regulations. For example, in § 201.304(b)(3)(i), which lists prohibited retaliatory actions, AMS revised the phrasing of the prohibition from “Termination of contracts or non-renewal of contracts” to “Terminating or not renewing a contract” to place emphasis on the action being prohibited rather than the subject of that action.
                    </P>
                    <P>
                        AMS also made several non-substantive clarifying changes to the wording of prohibited contractual deceptive practices in paragraphs (b) and (c) of § 201.306—Deceptive practices. These changes are identical under 
                        <E T="03">contract formation, performance, and termination</E>
                         and include the removal of the phrase “pretext” and “fact” and the inclusion of the term “information” in place of “fact.” The term “pretext” was removed because it is not needed to accomplish the objectives of § 201.306. The conduct this rule aims to prohibit is more directly defined through use of the following language: “
                        <E T="03">false or misleading statement or representation, or omission of material information.</E>
                        ” By changing the term “fact” to “information” certain conduct that may not be considered or defined as “factual” under the Act, yet is still deceptive, will be covered.
                    </P>
                    <P>Lastly, AMS made a technical change to the table of contents for subpart O. To avoid confusion, AMS is including §§ 201.303 and 201.305 in the table of contents as reserved sections to indicate the gaps between §§ 201.302, 304, and 306 are deliberate and that sections have not been inadvertently omitted.</P>

                    <P>Under the authority of the Act, this rule adds a new subpart O to AMS's regulations in 9 CFR 201, titled “Competition and Market Integrity,” and consisting of §§ 201.300 through 201.390. This section summarizes the substantive provisions of the new subpart.</P>
                    <HD SOURCE="HD2">A. Definitions (§ 201.302)</HD>
                    <P>
                        Section 201.302 defines three terms for subpart O: 
                        <E T="03">covered producer, livestock producer,</E>
                         and 
                        <E T="03">regulated entity.</E>
                          
                        <PRTPAGE P="16118"/>
                        A 
                        <E T="03">covered producer</E>
                         is defined as a livestock producer (as defined in § 201.302) or swine production contract grower or poultry grower as defined in section 2(a) of the P&amp;S Act (7 U.S.C. 182(8), (14)). Under section 2(a) of the Act, swine production contract grower means any person engaged in the business of raising and caring for swine in accordance with the instructions of another person. A live poultry grower is defined under section 2(a) of the Act as any person engaged in the business of raising and caring for live poultry for slaughter by another, whether the poultry is owned by such person or by another, but not an employee of the owner of such poultry. AMS is adopting this definition to facilitate a focus in this rule on protecting livestock producers (and other parties included in the definition of covered producer) because the harms of discrimination, retaliation, and deception that are addressed in this rule are directed toward and experienced by those persons. Therefore, even though the Act does not contain a definition for livestock producers, AMS has included livestock producers under the definition of 
                        <E T="03">covered producer;</E>
                         and provided a definition for the term 
                        <E T="03">livestock producer</E>
                         in this section.

                    <P>
                        <E T="03">Livestock producer</E>
                         is defined for the purposes of subpart O as being any person, except an employee of the livestock owner, engaged in the raising of and caring for livestock. AMS aligned its definition of the term 
                        <E T="03">livestock producer</E>
                         with phrasing used in the Act for the terms poultry grower and swine production contract grower. In response to comment to the proposed rule, AMS revised its definition by removing unnecessary and potentially confusing phrasing. Employees are specifically excluded as they typically lack direct financial interest in the livestock themselves.

                    <P>
                        AMS defines 
                        <E T="03">regulated entity</E>
                         as a swine contractor or live poultry dealer as defined in section 2(a) of the Act (7 U.S.C. 182(8)) or a packer as defined in section 201 of the Act (7 U.S.C. 191). A swine contractor is defined in the Act as any person engaged in the business of obtaining swine under a swine production contract for the purpose of slaughtering the swine or selling the swine for slaughter, if (a) the swine is obtained by the person in commerce or (b) the swine (including products from the swine) obtained by the person is sold or shipped in commerce. Live poultry dealers, the vast majority of whom are organized in a vertical structure with common ownership interest in inputs, often referred to as poultry integrators, are defined in the Act as any person engaged in the business of obtaining live poultry by purchase or under a poultry growing arrangement for the purpose of either slaughtering it or selling it for slaughter by another, if poultry is obtained by such person in commerce, or if poultry obtained by such person is sold or shipped in commerce, or if poultry products from poultry obtained by such person are sold or shipped in commerce. A packer is defined in the Act as any person engaged in the business (a) of buying livestock in commerce for purposes of slaughter; or (b) of manufacturing or preparing meats or meat food products for sale or shipment in commerce; or (c) of marketing meats, meat food products, or livestock products in an unmanufactured form acting as a wholesale broker, dealer, or distributor in commerce.

                    <HD SOURCE="HD2">B. Undue Prejudice and Unjust Discrimination (§ 201.304(a))</HD>
                    <P>Section 201.304(a) addresses the unique and often difficult to prove discriminatory conduct that has long existed in the agricultural sector by prohibiting specific bases of prejudicial action. Paragraph (a) also lists prohibited actions taken on a prejudicial basis and provides clarification on the types of actions that do not constitute prohibited action taken on a prejudicial basis. In doing so, AMS is clarifying the application of the Act, better empowering producers to protect themselves, and encouraging companies to adopt more robust compliance practices to snuff out conduct prohibited by the Act in its incipiency, before it can distort markets in the aggregate. In particular, this rule addresses the longstanding and often difficult to counter forms of exclusion that have plagued the agricultural sector for decades. AMS intends for this rule to support positive trends toward inclusivity in the marketplace. Prejudices and disadvantages based upon the producer's protected characteristics or status as a producers' cooperative have no place in today's modern agricultural markets.</P>
                    <P>The Act, through section 202(a) and (b), broadly prohibits certain practices or devices, including undue or unreasonable prejudices and disadvantages and unjust discrimination. Section 202(a) and (b) of the Act identifies several prohibited actions with respect to livestock, meats, meat food products, or livestock products in unmanufactured form, or for any live poultry dealer with respect to live poultry. In this rule, AMS is prohibiting specific undue and unreasonable prejudices and disadvantages, and unjust discrimination against any covered producer on the basis of certain categories of characteristics or attributes broadly and firmly established as unjust in a modern economy. This regulatory action implements Congress's intent, expressed through the Act, to stop unjust discrimination and undue prejudice by packers and live poultry dealers against livestock producers and poultry growers.</P>
                    <P>
                        In enacting the Act, Congress cast a wide net to capture all acts of unjust discrimination and undue or unreasonable prejudice against any particular person. There is no indication that Congress intended to exempt any discriminatory conduct taken by regulated entities against producers covered under the Act.

                         The Act's prohibition of unjustly discriminatory or unreasonably prejudicial actions against a particular person was not a new statutory concept, as the Interstate Commerce Act of 1887 (or ICA) also banned unreasonable prejudices and unjust discriminatory practices well before the enactment of the Act. While the ICA does not define the scope of the Act, the comparison is nevertheless useful, especially with respect to the structure and design of provisions governing undue prejudices. A comparison is provided in Table 4 below.

                         Further, the Court isolated a section of the ICA and noted that, “Paragraph 1 of Section 3 of the Act says explicitly that it shall be unlawful for any common carrier subject to the Act `to subject

                        The Act contains similar, but broader, language than sec. 3 of the ICA. Section 202 of the Act reads, “It shall be unlawful for any packer or swine contractor with respect to livestock, meats, meat food products, or livestock products in unmanufactured form, or for any live poultry dealer with respect to live poultry, to: (a) Engage in or use any unfair, unjustly discriminatory, or deceptive practice or device; or (b) Make or give any undue or unreasonable preference or

Jones concurring): “In all the cases discussed by the concurrence dealing with both terms [under the ICA], the defendant faced charges that it treated customers differently. According to the court, `railway companies are only bound to give the same terms to all persons alike under the same conditions.' If the conditions are different, then different treatment is merited. Further, `competition between rival routes is one of the matters which may lawfully be considered in making rates.' Differential treatment driven by competitive forces is not a violation. Acknowledging that competition can justify differential treatment of customers is different than requiring the plaintiff to prove anticompetitive harm to establish a violation.”

                        This rule sets forth specific prohibitions on prejudicial or discriminatory acts or practices against individuals that are sufficient to demonstrate violation of the Act without the need to further establish broad-based, market-wide prejudicial or discriminatory outcomes or harms. The prohibitions in this rule on regulated entities adversely treating individual producers address the types of harms the Act is intended to prevent. AMS finds that adverse acts on these bases are essentially unjust and unduly prejudicial, and actionable at the individual level. Moreover, AMS 
                        <PRTPAGE P="16120"/>
                        believes that preventing broad-based exclusion, and therefore promoting competitive markets, is most effectively enforced at the individual producer level when the conduct is in its incipiency.

                        In determining the bases for protection against discrimination under the Act, AMS drew insight initially from the Statement of General Policy Under the Packers and Stockyards Act published by the Secretary in 1968 (Statement of General Policy) (9 CFR 203.12(a)), which states that the Act provides that all stockyard services furnished at a stockyard “shall be reasonable and nondiscriminatory and stockyard services which are furnished shall not be refused on any basis that is unreasonable or unjustly discriminatory.”

                    <P>
                        The Statement of General Policy reflects the current USDA policy on the enforcement of the Act. The Statement of General Policy provides in part that it is a violation of secs. 304, 307, and 312(a) of the Act for a stockyard owner or market agency to discriminate, in the furnishing of stockyard services or facilities or in establishing rules or regulations at the stockyard, because of 
                        <E T="03">race, religion, color, or national origin</E>
                         of those persons using the stockyard services or facilities. Such services and facilities include, but are not limited to, the restaurant, restrooms, drinking fountains, lounge accommodations, those furnished for the selling, weighing, or other handling of the livestock, and facilities for observing such services.
                    </P>
                    <P>While this part of the Statement of General Policy applies to violations of secs. 304, 307, and 312(a) of the Act (related to the provision of services and facilities at stockyards on an unreasonable and discriminatory basis), almost identical prohibitive language is used in sec. 202 of the Act. Section 202 pertains to packers, swine contractors, and live poultry dealers. Section 202(a) of the Act prohibits any unjustly discriminatory practice or device with respect to livestock, meats, meat food products or livestock products in manufactured form, or live poultry.</P>

                        AMS also considered USDA's general regulatory prohibition against discrimination in USDA programs, which governs how USDA provides services to producers. In 1964, USDA prohibited discrimination on the basis of race, color, and national origin in its Federally conducted activities by adopting Title VI principles.

                        <FTREF/>
                         USDA then expanded the protected bases for its conducted programs to include religion, sex, age, marital status, familial status, sexual orientation, disability, and whether any portion of a person's income is derived from public assistance programs.

                         Most recently updated in 2014, the general regulatory prohibition offers a more current interpretation of antidiscrimination standards.

                        <FTREF/>
                         The 2014 rule aimed to “strengthen USDA's ability to ensure that all USDA customers receive fair and consistent treatment, and align the regulations with USDA's civil rights goals.” 
                        <SU>113</SU>
                        <FTREF/>
                         The relevant provision provides that no agency, officer, or employee of the USDA shall, on the grounds of race, color, national origin, religion, sex, sexual orientation, disability, age, marital status, family/parental status, income derived from a public assistance program, political beliefs, or gender identity, exclude from participation in, deny the benefits of, or subject to discrimination any person in the United States under any program or activity conducted by the USDA. In that rulemaking, USDA identified areas where discrimination against a producer is an unacceptable denial of access to USDA's services. This prior rulemaking provides a helpful reference to what constitutes unjust discrimination under the Packers and Stockyards Act.

                        The definitions and coverage in these statutes vary to some extent. Some focus principally on members of groups that have experienced racial or ethnic prejudices, while others address gender prejudices. Overall, these statutes and Congressional deliberations provide useful reference for USDA to most effectively carry out the Act, which outlaws undue prejudice against any person in any respect. For example, in the congressional hearings preceding the Act's passage, opposing members argued against the Act because producers were already protected by the ICA, which guaranteed “equal rights on the railroads to every man, woman and

                        Additionally, in crafting the final rule, AMS was informed by the provisions of two additional laws that fall under the enforcement of USDA with respect to livestock and poultry. The first is ECOA. ECOA prohibits a creditor from discriminating in the provision of credit on the basis of race, color, religion, national origin, sex (which includes sexual orientation and gender identity), marital status, or age, because the applicant's income derives all or in part from a public assistance program, or because the applicant has in good faith exercised any right under ECOA.

                        Secondly, AFPA protects producers from retaliation by certain market intermediaries, defined as handlers, for being members of a cooperative or seeking to form a cooperative.

                         The Secretary has delegated enforcement of the AFPA to AMS, which implements the law through the Packers and Stockyards Division. Congress has long protected the rights of agricultural cooperatives, acknowledging their important role in helping farmers meet the economic demands of the market. One year after the passage of the Act, Congress passed the Capper-Volstead Act (Pub. L. 67-146), which permits producer cooperatives to collectively process, prepare for market, handle, and market their products. In a decision related to an antitrust action against a nonprofit cooperative association whose members were involved in production and marketing of broiler chickens, the Supreme Court noted that farmers faced special challenges in the agricultural market and, therefore, cooperatives are afforded legal protections in helping them address those challenges.

They were subject to the vagaries of market conditions that plague agriculture generally, and they had no means individually of responding to those conditions. Often the farmer had little choice about who his buyer would be and when he would sell. A large portion of an entire year's labor devoted to the production of a crop could be lost if the farmer were forced to bring his harvest to market at an unfavorable time. Few farmers, however, so long as they could act only individually, had sufficient economic power to wait out an unfavorable situation. Farmers were seen as being caught in the hands of processors and distributors who, because of their position in the market and their relative economic strength, were able to take from the farmer a good share of whatever profits might be available from agricultural production. By allowing farmers to join together in cooperatives, Congress hoped to bolster their market strength and to improve their ability to weather adverse economic periods and to deal with processors and distributors.”).

                        AFPA provides enhanced protections to those seeking to form a cooperative. In particular, that statute prevents handlers from performing certain types of pricing and contract discrimination, coercion, and other practices that undermine cooperatives. As noted previously, the Act intended to improve the agricultural market and includes associations in the definition of “person” when referred to in the Act. The Act affords cooperative associations the same protections against discrimination as are afforded to all other covered producers.

                        In interpreting the Act in light of the aforementioned policy direction, AMS has sought to stamp out market exclusion on prohibited bases. This final rule establishes a prohibition of undue prejudice or unjust discrimination against covered producers on the bases of race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, marital status, or age; or because of the covered producer's status as a cooperative. Transitioning from the proposed rule's use of the more flexible “market vulnerable individual” to the more specific list of delineated terms, the final rule interprets the Act consistent with the antidiscrimination mandates in other related statutes, including the ECOA, which is already enforced by AMS for markets subject to the Act,

AMS also references the Equal Employment Opportunity Commission (EEOC) definitions (described below) for clarification regarding which characteristics a producer must possess to be considered a member of one or more protected classes. It is appropriate for the Secretary to consider these other authorities in effectuating the purposes of the Act as they effect a similar purpose to this final rule.

                        The EEOC has described racial discrimination as discrimination based on an “immutable characteristic associated with race, such as skin color, hair texture, or certain facial features.” Although race and color may appear indistinguishable, they are not. According to the EEOC, “color discrimination occurs when a person is discriminated against based on the lightness, darkness, or other color characteristic of the person.”

                         As explained above, in formulating this rule, AMS principally drew on its expertise and comments gathered from market participants about how undue discrimination manifests in markets, and considered the relevant references that concern this type of discrimination. These include the above referenced EEOC, ECOA, and AFPA-related approaches because these approaches: first, align with the intent of the Act to prohibit all instances of unjust discrimination and undue prejudice; second, effectuate the purposes of the final rule to clearly prohibit that discrimination; and third, promote more inclusive competition by protecting the individuals who participate in the market.

                        </P>
                    </FTNT>
                    <P>Because of the Act's broad applicability (as discussed in section III—“Authority”); the similar language used in secs. 202, 304, 305, and 312 of the Act; and the series of statutes outlining a range of prejudices identified as being deserving of public policy efforts to ensure full market access; AMS concludes that producers who have been subjected to discrimination, prejudice, disadvantage, or exclusion on the specific bases set forth in this final rule should be covered by the prohibitions against undue prejudice or disadvantage and unjust discrimination as enumerated by sec. 202 of the Act.</P>
                    <P>To stamp out unjustly discriminatory and unduly prejudicial conduct and support a more inclusive marketplace, AMS, in § 201.304, lays out the protected bases against which undue prejudices or disadvantages and unjust discrimination are prohibited, and then describes the specific conduct that, when initiated against a producer belonging to one of the protected bases, is prohibited. Paragraph (a)(1) prohibits a regulated entity from prejudicing, disadvantaging, inhibiting market access, or otherwise taking an adverse action against a covered producer on the basis of the covered producer's (i) race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, marital status, or age; or (ii) the covered producer's status as a cooperative. The sources of these bases are discussed above. Paragraph (a)(1)'s prohibition as “based upon” is intended to be broader than “but for” causation and so capture when the protected characteristics or status are a material, or non-trivial, element of the decision to take an adverse action against a covered producer. AMS expects that fact-finding tribunals will establish the necessary processes for proving these elements, with an eye toward the protections for covered producers and for open, inclusive markets that this rule is designed to provide.</P>
                    <P>Though this regulation prohibits prejudice or disadvantage against a covered producer on the basis of the specified statuses, AMS notes that regulated entities may decline to do business with covered producers for justified economic reasons. For example, a regulated entity may refuse to contract with a cooperative of covered producers when the contract would not be cost-effective for the entity, regardless of the cooperative status of the producers. In this hypothetical example, the regulated entity would not be unduly prejudicing cooperatives of covered producers based on their status as a cooperative. Instead, the regulated entity would have a nonprejudicial basis for its business decision.</P>
                    <P>
                        Section 201.304(a)(2) describes the actions that prejudice, disadvantage, inhibit market access, or are otherwise adverse under paragraph (a)(1). These actions were chosen because they relate to fairness in contracting, which is a consistent concern among producers; and are actions that PSD has determined are a recurring problem in the industry, directly impacting producers' financial well-being. In response to the proposed rule, many commenters noted the financial repercussions of lack of fairness in contracting.

                        Paragraph (a)(2)(i) prohibits the offering of less favorable contract terms to covered producers on the basis of their status as members of a protected class. In the Agency's experience, offering less favorable contract terms than those generally or ordinarily offered to similarly situated covered producers is a means through which regulated entities can prejudice or disadvantage producers. For example, the Agency has received complaints that the bidding on livestock by regulated entities occurs at a less advantageous time for certain producers on the basis of the classes protected under this rule resulting in lower prices or less favorable delivery terms. Similarly, in the Agency's experience, poultry growers have complained about being offered less favorable growing terms on the basis of the classes protected under this rule. This rule does not prohibit ordinary contracting for different prices on the basis of differences in product 
                        <PRTPAGE P="16123"/>
                        quality, service, transportation cost, or delivery terms.
                    </P>
                    <P>Paragraph (a)(2)(ii) prohibits regulated entities from refusing to deal with a covered producer on terms generally or ordinarily offered to similarly situated covered producers. This refers to situations in which a regulated entity makes no reasonable effort to deal, bid, or negotiate with a covered producer on the basis of the covered producer's status as a member of a protected class. Such refusal to deal has no connection with the service or quality of product offered, but rather is due, in material part, to the personal characteristics or status of the producer and restricts the producers' ability to obtain the fair market value of their products and services. In today's highly vertically integrated and concentrated markets, refusal to deal by one regulated entity will often leave a producer with very few, if any, parties to contract with, unduly inhibiting the competitive marketplace when performed on the bases prohibited by this final rule.</P>
                    <P>Paragraph (a)(2)(iii) prohibits regulated entities from performing under or enforcing a contract differently than with similarly situated producers. A violation of this regulation would occur when a regulated entity—based upon the covered producer's protected characteristics—inconsistently enforces its contracts as it would with similarly situated producers. For instance, a selective information disclosure would represent a selective performance of contract when a regulated entity withholds materially relevant information from one covered producer that the regulated entity generally or ordinarily provides to other covered producers. In these instances, information-deprived producers will have an incomplete picture of their business relationships with regulated entities, and therefore will operate at an unreasonable disadvantage relative to producers who receive the pertinent information. Similarly, the Agency has received complaints over the years with respect to differential performance under poultry growing arrangements, such as the delivery to affected growers of flocks that are sick or otherwise known to be likely to perform poorly owing to the age of the hens. Those sick or poor performing chicks are likely to result in lower performance for the grower in a poultry grower ranking system, which results in lower pay for the grower. While that may occur from time to time per natural cycles, a repeated or intentional delivery of underperforming flocks has been commonly reported by producers as a principal means of adversely affecting grower earnings. Similarly, a regulated entity withholding or delaying delivery of feed would result in lower performance and profit for a producer. Accordingly, AMS has incorporated differential contract performance to capture those contractual performance-based means to prejudice or disadvantage producers. By clarifying in its final rule that the Act prohibits such conduct, AMS seeks to better protect producers who suffer, or are at risk of suffering, this type of harm.</P>
                    <P>
                        Paragraph(a)(2)(iv) prohibits a regulated entity from, on the basis of a covered producer's protected status, requiring a contract modification or renewal on terms less favorable than those for similarly situated covered producers. The Agency has determined, based on producer complaints, that regulated entities sometimes prejudice or disadvantage growers by reducing numbers of flocks delivered, changing types of birds raised, or otherwise changing contract terms that result in lower incomes for growers. Poultry producers commonly experience these types of contract modifications. Livestock producers also experience modifications, such as a change from a cash negotiated contract to a negotiated grid contract or other purchase type that may be adverse from the perspective of the producer depending on the facts and circumstances. Therefore, in the final rule, AMS seeks to clarify that unfavorable contract modification or renewal by a regulated entity, on the basis of a protected class, amounts to a violation under the Act. This rule, by itself does not prohibit renegotiations or failure to renew a contract on the basis of changes in the market. However, while this rule does not distinguish modification for other reasons, many contract terms under the Act are not subject to modification during performance of the contract 
                        <E T="03">at all</E>
                         because any contract modification that serves to delay or reduce full payment is an unfair practice under sec. 202(a) of the Act.
                    </P>
                    <P>Paragraph (a)(2)(v) prohibits regulated entities from terminating or not renewing a contract with a covered producer on the basis of a covered producer's status as a protected class. Contract termination can have devastating consequences for producers that have invested substantial sums in infrastructure that only meets the requirements of a particular integrator.</P>
                    <P>Paragraph (a)(2)(vi) prohibits regulated entities from any other action that a reasonable covered producer would find materially adverse. This provision provides a broad and flexible approach to these prohibitions and allows for “material” to be determined by the facts and circumstances of each case where producers were harmed.</P>
                    <P>Finally, § 201.304(a)(3) delineates two exceptions to the prohibition on prejudicial or discriminatory conduct against covered producers on a protected basis. In one, the regulated entity is fulfilling a religious commitment relating to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry; in the other, a Federally recognized Tribe, including its wholly or majority-owned entities, corporations, or Tribal organizations, is performing Tribal governmental functions. As discussed in Section V—Changes from the Proposed Rule, these exceptions were added in response to commenters' request that some exceptions be provided to the prohibition on undue prejudice and unjust discrimination. To safeguard the free exercise of religion, AMS has provided an exception to allow discriminatory conduct necessary to fulfill religious commitments surrounding livestock care and meat production. To conform with longstanding jurisprudence surrounding Tribal sovereignty, AMS has provided an exception to allow Tribal entities to preference their own Tribal members in the purchase and sale of livestock.</P>

                    <P>
                        Section 201.304(b) establishes protected activities for covered producers and prohibits regulated entities from engaging in retaliatory conduct based on those activities. As noted previously, sec. 202(a) of the Act prohibits unjust discrimination. This regulation is designed to protect the essential activities producers must engage in to bargain effectively and exercise their economic rights, and in doing so obtain the full value of their livestock or poultry products or services. As a result, retaliation against producers because they have engaged in protected activities is disparate treatment that the Act intended to prohibit.

                    </FTNT>
                    <P>AMS determined the protected activities to include in § 201.304(b)(2) based on commonly recorded complaints from the industry, case law, USDA/DOJ workshops, conversations with AMS personnel, and a recently voiced concern from Congress. AMS also identified these types of activities because of their potential to mitigate certain ways that market power is exercised. The retaliatory conduct prohibited by this regulation covers a broad range of circumstances that AMS has determined occur commonly in connection with livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry. Free exercise of the protected activities facilitates a competitive and transparent market, ensuring producers can capture the full value of their livestock or growing services.</P>
                    <P>Section 201.304(b)(1) establishes that a regulated entity may not retaliate or otherwise take an adverse action against a covered producer based upon the covered producer's participation in protected activities. As described in Section V—Changes from the Proposed Rule,” paragraph (b)(1)'s prohibition as “based upon” is intended to be broader than “but for” causation and so capture when the protected characteristics or status are a material, or non-trivial, element of the decision to take an adverse action against a covered producer.

                        Section 201.304(b)(2) lists the activities that are protected. Paragraph (b)(2) also provides a caveat that the protected activities must not otherwise be prohibited by Federal, Tribal, or State law, including antitrust laws. As outlined in the following paragraphs, these activities form an essential foundation for producers to receive the benefit of their bargained for exchange and the protections afforded under the Act itself. Acts of retaliation to chill or curtail these protected activities offer no competitive benefits to the market. Commenters to the proposed rule echoed these concerns.

                    <P>Specifically, paragraph (b)(2)(i) protects a covered producer's ability to communicate with a government entity or official or to petition a government entity or official for redress of grievances with respect to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry. A covered producer must be able to freely seek redress of grievances to ensure the protections afforded by the Act and its regulations have their intended effect. Government regulators must also have the ability to fully appreciate the views of market participants to ensure that the rules and regulations—and enforcement of those laws and regulations—are sufficiently responsive to market realities and divergent interests and business practices in the marketplace. Hindering the free flow of market information creates risks of market distortions and will impair the ability for those with less economic power to operate in the marketplace.</P>
                    <P>In paragraph (b)(2)(ii), AMS adds a new protection for a covered producer to refuse a regulated entity's request that the producer communicate with a government entity or official when that communication is not required by law. Just as covered producers have the right to communicate with government entities or officials to ensure their rights are protected, so too do they have the right to decide when and under what circumstances they engage in such communication. Based on its experience regulating the livestock sector, AMS is aware that regulated entities may coerce covered producers to contact the government on regulatory and policy matters and to espouse positions that the covered producers disagree with. AMS has received reports frequently in the past, and including within the last two years, of regulated entities pressuring producers to oppose regulations that the producers support, and covered producers reported similar concerns to AMS during earlier rulemaking initiatives as well. Indeed, regulated entities should not punish a covered producer for the producer's decision to talk to government agencies or not, regardless of the producer's reasons.</P>
                    <P>The lack of clarity around prohibitions on retaliation in agricultural markets—clarity which this rule aims to provide—impairs AMS's ability to investigate potential violations and effectively enforce the Act. Accordingly, AMS has added § 201.304(b)(2)(ii) to clarify that the rule protects a covered producer from retaliation if the covered producer decides not to engage in a communication with a government entity or official that is not required by law.</P>
                    <P>
                        Paragraph (b)(2)(iii) protects a covered producer asserting the right to formor join—or to refuse to form or join—aproducer or grower association or organization, or cooperative, or the right to collectively process, prepare for market, handle, or market livestock or poultry. “Asserting the right” includes the preparatory steps necessary to form or join an association or cooperative. This provision protects two forms of producer interactions: cooperative and non-cooperative associations. The formulation “to collectively process, prepare for market, handle, or market livestock or poultry” refers to forming or joining a cooperative, tracking the language of the Capper Volstead Act.

The Agricultural Fair Practices Act explicitly protects the right of individual farmers to join cooperative organizations to preserve their marketing and bargaining position, stating that “[i]nterference with this right is contrary to the public interest and adversely affects the free and orderly flow of goods” (7 U.S.C. 2301).

                        against regulated entity coercion because they afford covered producers the opportunity to combine their resources to potentially counteract market imbalances and capture opportunities at scale. For example, they provide a means for covered producers to share information regarding the production of poultry and livestock (within permissible scope of the Federal antitrust laws) even when a cooperative is not feasible. They also enable producers to potentially uncover and address problematic practices in the industry, including through working together to reduce the risk of seeking redress of grievances, among other benefits. Some producer associations also provide means for producers to obtain lower cost inputs, such as gasoline. AMS believes that retaliating against producers for engaging in these activities hinders the free flow of information and hampers producers' ability to fairly compete in the market and realize full value of their livestock and poultry. An assertion of rights in both these contexts may involve expressing interest or intent to engage in these activities or engaging in these activities.
                    </P>
                    <P>Paragraph (b)(2)(iii) also protects a covered producer's right to refuse to join a producer or grower association or organization. AMS added protection for refusing to form or join a producer or grower association or organization in response to public comment on the proposed rule, as commenters noted that producers have experienced pressures from regulated entities to join certain organizations that may express views or interests in the livestock or poultry industry that are contrary or not fully reflective of the producer's views regarding their own interests.</P>
                    <P>Paragraph (b)(2)(iv) protects a covered producer's ability to communicate or cooperate with a person for the purposes of improving production or marketing of livestock or poultry. “A person” is intended to be broad, and includes USDA's Extension and other academic experts, businesses and associations, advisors and associates of the covered producer, other covered producers, including someone under contract with the same regulated entity. This regulation protects a covered producer's ability to communicate or cooperate with other persons, including efforts to obtain higher or otherwise more appropriate compensation from regulated entities, to the extent permissible under Federal antitrust laws and cooperative laws. Protecting such communications enables the producer to obtain help to enhance their ability to compete in the market. Such communication may include, for example, communication with extension programs or with independent veterinarians and animal health experts. It would also include communications with persons—including other producers—relating to potential illegal market abuses, anticompetitive conduct, or otherwise illegal conduct by regulated entities, as that conduct would obstruct the covered producer's ability to secure the full value of their livestock or poultry product or services. AMS notes that communications on these matters when with the government would be protected by paragraph (b)(2)(i), and would include but not be limited to communications with: USDA; the U.S. Department of Justice; the Federal Trade Commission; a State or Tribal attorney general or agriculture department; or a Federal, State, or Tribal legislative office or committee or judicial tribunal.</P>
                    <P>Paragraph (b)(2)(v) protects a covered producer's ability to communicate, negotiate, or contract with a regulated entity, another covered producer, a commercial entity, or a consultant for the purpose of exploring or entering into a business relationship. The purpose of the provision is to preserve and promote the competitive position of the covered producer and ensure that a regulated entity's retaliation does not discourage a covered producer from seeking competitive alternatives. It affords producers the opportunity to realize the full market potential of their products and services and participate in the market fully, including through price discovery and competition between multiple regulated entities. For example, a covered producer may want to seek information from a regulated entity with which they do not currently have a business relationship regarding the possibility of a future business relationship, such as entering into a contract. Or, a covered producer may enter into a contract to sell livestock in the market or through an auction or exchange. Protecting these activities allows covered producers to freely compare potential business relationships and choose between several regulated entities, encouraging competition. As also discussed in Section V—Changes from the Proposed Rule, communications of this type can improve production efficiency and price discovery mechanisms. Restricting participation in these activities forecloses full market participation by producers.</P>
                    <P>Paragraph (b)(2)(vi) protects a covered producer's ability to support or participate as a witness in any proceeding under the Act or any proceeding that relates to an alleged violation of any law by a regulated entity. Because of the close-knit and concentrated markets in which covered producers operate, AMS believes that protecting some covered producers as witnesses may enable other covered producers to effectuate their rights under the Act and related laws, which would improve market integrity in the markets governed by the Act. Without such protections, enforcement of the Act may be frustrated overall.</P>
                    <P>
                        Finally, paragraph (b)(2)(vii) protects a covered producer's ability to assert any of the rights granted under the Act or the regulations in 9 CFR 201, or to assert rights afforded by their contract. These rights include, for example, producers' rights to view the weighing of flocks, which is legally protected but which producers have complained is not practically enforceable. In the 2010 USDA-DOJ public workshop on the poultry market, a grower said he was retaliated against for asserting his right to view his flock being weighed; the integrator “cut me off from growing business and cost me hundreds of thousands of dollars.”

                        Section 201.304(b)(3) enumerates the actions that are retaliation or an otherwise adverse action under paragraph (b)(1) of this section. The final rule intends to capture the widest range of conduct harmful to producers, where such harms are based upon activities protected by the rule. The focus in any inquiry under this final rule is whether the regulated entity has engaged in harmful conduct in whole or material part because a covered producer engaged in any protected activity. To provide examples of what activities are materially harmful to a reasonable covered producer, paragraph (b)(3) sets out that regulated entities are prohibited from (i) terminating or not renewing a contract with a covered producer; (ii) performing under or enforcing a contract differently than with similarly situated covered producers; (iii) requiring a contract modification or a renewal on terms less favorable than those for similarly situated covered producers; (iv) refusing to deal with a covered producer on terms generally or ordinarily offered to similarly situated covered producers; (v) interfering in farm real estate transactions or contracts with third 
                        <PRTPAGE P="16126"/>
                        parties; (vi) taking any other action that a reasonable covered producer would find materially adverse.
                    </P>
                    <P>Paragraph (b)(3)(i) prohibits terminating or not renewing a contract with a covered producer because the covered producer has engaged in protected activities. This practice can have devastating consequences for producers that have invested substantial sums in infrastructure that only meets the requirements of a particular regulated entity. Furthermore, in concentrated markets, losing a contract may put a producer out of business as the producer has few, if any, other livestock or poultry buyers to whom they can sell livestock or poultry.</P>
                    <P>Paragraph (b)(3)(ii) prohibits performance under or enforcement of a contract differently as compared to performance under or enforcement of contracts for similarly situated covered producers as retaliation for engaging in protected activity. Depending on the facts and circumstances of the case, the “similarly situated producer” could be the covered producer's own status quo prior to engaging in the protected activity. A violation of this regulation would occur when a regulated entity, in response to a producer engaging in protected activities, inconsistently enforces its contracts compared with contract enforcement for similarly situated producers. For instance, the Agency has received complaints over the years with respect to differential performance under poultry growing arrangements, such as the delivery to affected growers of flocks that are sick or otherwise known to be likely to perform poorly owing to the age of the hens, differential delivery of feed, or other differential treatment such as early or delayed harvest of birds. Those actions are likely to result in lower performance for the grower in a poultry grower ranking system, which results in lower pay for the grower. While that may occur from time to time per natural cycles, a repeated or intentional delivery of underperforming flocks has been commonly reported as a principal means of adversely affecting grower earnings. Accordingly, AMS has incorporated differential contract performance to capture those contractual performance-based means that a regulated entity may use to retaliate against producers for engaging in protected activities.  </P>
                    <P>Paragraph (b)(3)(iii) prohibits requiring a contract modification or a renewal on terms less favorable than those for similarly situated covered producers as retaliation for engaging in protected activity. Depending on the facts and circumstances of the case, the similarly situated producer could be the covered producer's own status quo prior to engaging in the protected activity. In this final rule AMS seeks to clarify that unfavorable contract modification or renewal by a regulated entity, if it's the result of a producer engaging in a protected activity, is retaliatory conduct and amounts to a violation under the Act. This behavior is a common way for regulated entities to retaliate against producers by, for example, reducing the number of flocks or their density, changing types of birds raised, or otherwise changing contract terms that result in lower incomes for growers. As another example, if a regulated entity requires a capital investment from a covered producer as part of a contract modification or contract renewal that the regulated entity is not requiring of similarly situated producers, this requirement would be a violation of paragraph (b)(3)(iii) if the regulated entity is requiring the capital investment in retaliation for the covered producer's participation in a protected activity.</P>
                    <P>Paragraph (b)(3)(iv) prohibits refusing to deal with a covered producer on terms generally or ordinarily offered to similarly situated covered producers. A violation of this regulation could occur if a regulated entity makes no reasonable effort to bid or negotiate or fails to reasonably attempt to contract in good faith with a covered producer, due in whole or material part to a producer's prior, or current, participation in protected activities. In this context, the regulated entity's refusal to deal is not connected with the service or quality of the product offered, but rather is material in part due to the producer exercising his or her rights to engage in protected activities. A similarly situated producer may, depending on the facts and circumstances, be the producer's own prior status quo with the regulated entity before the producer engaged in a protected activity. This provision includes scenarios in which cattle producers operate in the cash market for livestock. While some cattle producers may only be in the cash market a few times a year, others may be in the cash market weekly. In the latter case, this provision would cover certain types of retaliation. If a producer sells cattle to a particular packer every week, and then one week the packer refuses to buy the producer's cattle or offers significantly less favorable terms after the producer engaged in a protected activity, this would constitute retaliation under this rule absent evidence of changed business conditions necessitating the packer's refusal to deal. AMS believes that retaliating against a producer in this way is conduct the Act seeks to remedy because it raises a barrier to competitive entry to the market by decreasing the number of parties a producer can do business with, which in effect is a market failure.</P>
                    <P>
                        Paragraph (b)(3)(v)'s prohibition on interfering with a covered producer's farm real estate transactions or with their contracts with third parties is a prohibition against conduct that a regulated entity may engage in due to the unequal power dynamic that exists between producers and the few firms available for them to contract with. This conduct may take several forms but has been observed most commonly to occur when a producer attempts to sell its farm to a third party and in doing so must terminate or fail to renew their existing contract with a regulated entity. In these situations, the regulated entity may choose not to guarantee a similar contract, or any contract at all, to the prospective buyer. Without this guarantee, banks and prospective buyers are unlikely to enter the farm real estate transaction because the land is of little use to them without a contract to grow livestock or poultry. This is often seen in the poultry sector, where it is alleged that regulated entities use the potential transfer of farm real estate as an opportunity to require growers to make capital improvements in exchange for their guarantee to contract with the new grower. This becomes retaliatory because the unreasonable refusal to guarantee a future contract with a prospective landowner or operator dramatically lowers the value of the farm operation, to the point of obstructing the transfer of the real property by the landowner, and yet the debt burden on the farm is commonly incurred in response to the regulated entity's requests for additional capital investments. The seller of farm real estate faces an unjust extraction, or else they are unable to sell land, as the cost of capital improvements required by the regulated entity in exchange for a guarantee to contract with a new owner or operator is not a freely-determined agreement. Farm sales transactions are not, however, the only circumstance where a regulated entity can retaliate against a covered producer through contracts with third parties. For example, covered producers have sought to develop new marketing opportunities for their livestock and poultry through collectively processing their product. If the regulated entity sought to obstruct the sale of the meat or poultry products through distribution or retail chains as retaliation against a 
                        <PRTPAGE P="16127"/>
                        covered producer with a material interest in the meat or poultry sales organization, that interference would be covered by this rule.
                    </P>
                    <P>Paragraph (b)(3)(vi) prohibits any other action that a reasonable covered producer would find materially adverse. This regulation is designed to account for a broader scope of actions that are considered retaliatory. Under this provision any conduct would be considered prohibited retaliation if such conduct caused material harm to the covered producer relative to the covered producer's situation prior to the allegedly retaliatory conduct, or relative to conduct toward similarly situated producers. This provision provides a broad and flexible approach to these prohibitions and allows for “material” to be determined by the facts and circumstances of each case. As discussed under Section V—Changes from the Proposed Rule, some retaliatory activities may occur outside the confines of contractual relationship, for example, a regulated entity's interference in a covered producers' water rights. The provision also covers the act of making a threat to engage in an action where the threat can reasonably be foreseen to change the producer's conduct or where the threat delivers a reasonable possibility of material harm.</P>
                    <P>When regulated entities punish covered producers or deny them opportunities afforded to other covered producers for engaging in certain activities, it is an unjustly discriminatory practice. Not only do retaliatory practices harm individual covered producers; recurrent instances and patterns of retaliation erode market integrity and discourage fairness and competition in the livestock and poultry markets. Under § 201.304(b), AMS is providing greater clarity, specificity, and certainty as to how the Act applies with respect to retaliatory behavior. This will facilitate higher levels of compliance by regulated entities, enable AMS to better enforce the Act, and position producers to better assert their rights under the Act.</P>

                         The recordkeeping requirement in this rule is not new. AMS currently has the authority to require regulated entities to create, maintain, release to AMS, and dispose of records through the Act and its regulations, including sec. 401 of the Act and 9 CFR 201.94, 201.95, and 203.4. Section 401 of the Act requires regulated entities to keep “such accounts, records, and memoranda as fully and correctly disclose all transactions involved in his business . . .” (7 U.S.C. 221). Such records may include details of a single transaction, such as the name of the owner of the livestock or poultry, date, weight of livestock or poultry, number of head of livestock, and unit price; all elements necessary to recreate the total sum paid to the producer or grower by the regulated entity. Existing regulations under 9 CFR 201 require regulated entities to give the Secretary “any information concerning the business . . .” (§ 201.94) and provide authorized representatives of the Secretary access to their place of business to examine records pertaining to the business (§ 201.95). Section 203.4 is another relevant existing regulation with respect to the types of records to be kept by regulated entities and the timelines for disposal of these records by the regulated entities.

                    <P>Existing gaps in both generally applicable agricultural and PSD-specific data collection make addressing widespread reports of discriminatory behavior difficult. Access to the types of records required by § 201.304(c) will assist AMS in assessing the effectiveness of a regulated entity's compliance with § 201.304(a) and (b). Therefore, this recordkeeping requirement is critical for AMS to fulfill its duties to prevent, and if necessary secure enforcement against, undue and unreasonable prejudice and unjust discrimination.</P>
                    <P>
                        AMS believes that this recordkeeping approach—at both the regulated entity policy and procedural level, as well as at the transactional level—will enable the Agency to monitor and facilitate a regulated entity's approach to compliance. Recordkeeping will encourage regulated entities to adopt more robust compliance practices to stamp out conduct prohibited by the Act in its incipiency. It will also enable AMS to uncover conduct that violates the rule in any investigation—a deterrent which will also strengthen compliance. AMS underscores that the tone and compliance practices set by senior executives play a vital role in establishing a corporate culture of compliance, which is a critical first step toward more inclusive market practices. Thus, relevant records may include those at the highest levels, such as relevant accountability practices of the board of directors. In addition to the importance of policies and procedures in developing a corporate culture of compliance, this rule maintains that transactional records, where decision-making occurs, are also important records to keep and to help AMS understand why an adverse action was taken against a producer or grower by a regulated entity. These records may include the number and nature of complaints received relevant to this section; in addition to records already required to be retained under § 203.4, such as buyers' estimates; buying or selling pricing instructions and price lists; correspondence; telegrams; or teletype communications and memoranda relating to matters other than contracts, agreements, purchase or sales invoices, or claims or credit memoranda.

While providing the authority for regulated entities to keep certain records, sec. 401 of the Act does not provide guidance on when records can be disposed. Existing regulation at 9 CFR 203.4 provides for a disposal date of two years, with an exception for certain records that may be disposed of after one year. This rule extends the disposal date of most records from two years to five years to promote efficient USDA monitoring efforts. For some records, the current disposal date is one year, which could be extended to five years under this rule if they are deemed relevant to showing compliance with this rule. Most records, such as specified in sec. 401, “such accounts, records, and memoranda as fully and

                    <P>
                        Section 201.306 is designed to broadly address deceptive practices in the marketplace by establishing four categories where deceptive practices commonly occur: contract formation, contract performance, contract termination, and contract refusal. Overall, the final rule addresses areas of concern regarding deception in contracting but does not exhaustively identify all deceptive practices that violate sec. 202(a) of the Act. Through this rule AMS aims to promote a marketplace that is free from the type of injury the Act was designed to prevent. False or misleading statements, or omissions of material information, during the contracting process or operation or termination of that contract, are prohibited deceptive practices because they prevent or mislead sellers or buyers from making informed decisions concerning their livestock or poultry operations. Deception puts honest businesses at a competitive disadvantage; and may even cause them to adopt deceptive practices.

                         To capture a range of longstanding approaches to deception that USDA has taken under the Act, AMS is prohibiting the use of false or misleading statements, or omission of material information during contract formation, performance (including enforcement or not enforcement of the contract), and termination. This rule also prohibits regulated entities from providing false or misleading information to a covered producer or a producer association concerning a refusal to contract. During this rulemaking process, AMS also considered the FTC's interpretation of sec. 5 of the FTC Act regarding deceptive acts or practices, “FTC Policy Statement on Deception.”

                        More than 100 years of history illustrate the types of conduct prohibited as deceptive by the Act, which provides a foundation for some of the specific deceptions that this rulemaking addresses. The regulations implemented by this rulemaking are not the first to prohibit deception. Current regulations under the Act require honesty in weighing (9 CFR 201.49 and 201.71), price reporting (§ 201.53), fees (§ 201.98), and business relationships (§ 201.67). Even when considering whether termination of a contract violated the Act, AMS currently considers the quality of the communication, and therefore considers its honesty (see § 201.217). Past cases indicate that USDA's approach, generally, is to view representations, omissions, and practices from the perspective of a reasonable party receiving them and determine if those deceptions affect the conduct or decision of the recipient. As the court explained in

                        AMS aims to have regulated entities be truthful and straightforward—that is, not misleading—in their dealings with producers. With § 201.306, AMS seeks to uncover the true motive for a regulated entity's treatment of a producer with whom they are forming or have a contractual relationship. Whether contract language was clear and written in a language the producer understands will be part of any evaluation to determine whether a statement (including any omission) was false or misleading; that determination will be dependent on the particular facts and circumstances of the contract. Violations of the Act that would constitute deceptive practices include false statements or omissions that are material in that they prevent sellers or buyers from making an informed business decision.

                         Thus, obvious falsehoods, such as false weighing and false accounting, have always been considered deceptive practices under sec. 202(a) of the Act. Another obvious falsehood—delivering checks drawn on accounts with insufficient funds, whether for livestock or meat—is also deceptive. Moreover, the Act requires honest dealing, so misleading omissions of material information necessary to make a statement not false or misleading are also prohibited. Prohibited omissions include failure to tell a business partner that the regulated entity was receiving a commission from a competitor,

                        Producers should not be misled with respect to their business decision-making with regulated entities. Deception can prevent producers from obtaining the full value of their products and services. In markets pervaded by deception, formerly honest businesses may be compelled to adopt deceptive practices if they are to remain competitive.

For these reasons, this final rule establishes a robust regulatory framework prohibiting deceptive practices in a range of contracting circumstances. Such a framework should provide a broad, although non-exhaustive, set of prohibitions to provide greater certainty for producers and regulated entities alike in the integrity of business dealings in the livestock and poultry markets.

This phrasing, which has been used in previous rules under the Act, points to the broadest possible interpretation of the Act's jurisdiction over regulated entities' conduct.</P>
                    <P>
                        Section 201.306(b) prohibits a regulated entity from making or modifying a contract with a covered producer by employing a false or misleading statement, or omission of material information necessary to make a statement not false or misleading. Preventing false or misleading representations, express or implied, or failing to provide the necessary information necessary to make a representation not misleading during the contracting process, are some of the most basic protections of the integrity of the marketplace. “By employing” captures the materiality of the false or misleading representation in that the representation formed a material part of the action under making or modifying the contract. Case law applying the Act illustrates some of the forms of deception that regulated entities may take during the offering or formation of a contract with producers. While some consumer-focused cases under the Act have addressed false advertising—specifically bait-and-switch advertising that occurs through advertising on price when, in fact, the customer has to pay a higher price at the point of sale,
                        <SU>154</SU>
                        <FTREF/>
                         a regulated entity's failure to disclose information to a covered producer has also been held to be deceptive under certain circumstances. The Act's purposes include protecting farmers and ranchers from receiving less than fair market value for their livestock and protecting consumers from unfair practices. Among the means employed to accomplish this purpose is the use of surety bonds. Sellers of livestock are entitled to the protection of a packer, dealer, or market agency's surety bond securing its obligations. Failure to maintain an adequate bond is therefore a deceptive practice.
                        <SU>155</SU>
                        <FTREF/>
                         When a packer fails to maintain a bond, the seller does not know that the sale is unsecured, and therefore the seller is at greater risk of nonpayment.

                         False weighing can occur in various ways. In some cases, the regulated entity records inaccurate weights using an improperly calibrated scale. In other cases, a regulated entity uses the scale improperly. In all these cases, false weighing is a plain and straightforward instance of a false statement that is material to the reasonable producer. Even if a regulated entity does not intentionally set out to deceive with respect to the weight of livestock, the Act does not require proof of a particularized intent.

                         Short weighing alone is enough to be an unfair and deceptive practice under the Act, without regard to the competitive injury the short weighing causes.

                        False or inaccurate grading has the same effect as false weighing because deceptive grading prevents the seller from receiving the full value of their livestock or poultry. A USDA Judicial Officer found a deceptive practice when a packer failed to inform hog producers of a change in the formula it used to estimate lean percent in hogs. Lean percent was one factor used in determining price when the packer purchased hogs on a carcass merit basis. USDA determined that nearly twenty thousand lots of hogs were purchased under the changed formula without notice to producers, resulting in payment of $1.8 million less than they would have received under the previous formula.

                    <P>Section 201.306(d) prohibits a regulated entity from terminating a contract with a covered producer by employing a false or misleading statement, or omission of material information necessary to make a statement not false or misleading. Employing false or misleading representations, express or implied, or failing to provide the necessary fact or information necessary to make a representation not misleading—critical protections during the performance or enforcement of contracts—are similarly fundamental to the integrity of the marketplace. “By employing” captures the materiality of the false or misleading representation in that the representation formed a material part of the action under performing or enforcing the contract. AMS draws on its experience in establishing the need for this prohibition. AMS notes, for example, that poultry growers complain of companies terminating their broiler production contracts based on pretext or for a deceptive reason. Contract termination puts the grower at severe risk of significant economic loss. The potential loss includes not only the loss of production income but also a grower's farm or family home, since a production broiler house construction is often financed with mortgages on those assets. Pretextual cancellation, in the form of false or misleading representations or material omissions, may also make even the sale or transfer of the broiler production house impossible because purchasers may be unable to determine if the broiler houses have value.</P>
                    <P>
                        AMS included the prohibition against false or misleading information or material omissions in paragraphs (b) through (d) to protect producers from conduct that employs deceit to disguise a regulated entity's genuine motive. A poultry producer stated in a public workshop that he relied upon cash flow statements provided by the integrator to secure a loan for his operation only to find out later “that the document wasn't accurate from the first flock that I placed and set. The capital investment of these facilities, while they may be greatly benefiting the integrator, are not returning any value to us whatsoever.”

                         In another public comment, a poultry producer asserted that he is “not given a clear picture of the integrator's operating procedures until after a contract has been signed. The contracts are very biased and one-sided, giving the bulk of control and authority to the initiator of the contract and then, only after you have committed to playing their game you are then given the rule book.”

                    <P>Section 201.306(e) prohibits a regulated entity from providing false information to a covered producer or association of covered producers concerning a refusal to contract. Deception related to refusal to contract is an unlawful practice designed to exclude producers from livestock and poultry markets. For example, if a producer association is asking on behalf of its members why a regulated entity is not executing any deals in the cash market and the entity lies about why it is avoiding the cash market, this could impede market entry for the association's members. Owing to the risk of retaliation, even with this final rule in place, a covered producer may depend upon a producer association to obtain the necessary understanding why the regulated entity is engaging in certain practices in the market, such as refusing to contract with covered producers.</P>
                    <P>A regulated entity that refuses to contract on unlawful grounds may well choose to hide their motives with misleading or deceptive statements. This regulation recognizes false and misleading statements made as justification of a refusal to enter into a contract as “deceptive” within the meaning of the Act. However, when refusing to enter into a contract, a regulated entity is not required to explain its reasoning so long as it does not offer a false or misleading statement to a covered producer.</P>
                    <P>Producers and consumers cannot make rational decisions in a dishonest market, and honest competitors cannot compete when regulated entities deceive. With this rulemaking, AMS is adding § 201.306 to its existing deception regulations under the Act to provide a broad array of coverage regarding the general circumstances that encourage the provision of false or misleading information in contracting. This regulation does not provide an exhaustive list of instances of deceptive practices; rather, it establishes four categories where deceptive practices commonly occur. The intent is to provide guidance to covered producers on how to effectuate their rights under section 202(a) of the Act and to promote a marketplace that is free from the type of injury section 202(a) was designed to prevent. AMS will investigate any alleged violations of this regulation and its determination will depend on the facts and circumstances of each case.</P>

                    <P>AMS is adding § 201.390, “Severability,” to new subpart O to confirm that if any provision of subpart O, or any component of any provision, is declared invalid or if the applicability thereof to any person or circumstances is held invalid, it is AMS's intention that the validity of the remainder of this subpart or the applicability thereof to other persons or circumstances shall not be affected thereby with the remaining provision, or component of any provision, to continue in effect. Such a provision is typical in AMS regulations that cover several different topics and is included here as a matter of housekeeping.</P>
                    <P>
                        This rule aims to address concerns around unduly prejudicial, unjustly discriminatory, retaliatory, and deceptive conduct in the livestock and 
                        <PRTPAGE P="16131"/>
                        poultry industry to the broadest jurisdiction of the Act. This new subpart has two sections that prohibit unduly prejudicial, unjustly discriminatory, and deceptive practices. This regulation is intended to take a series of regulatory actions, within this rulemaking, to address several different harms on the same or similar subjects but not prohibit identical conduct. The wrongful conduct addressed in the undue prejudice and discrimination, retaliation, and deception provisions are each different—the first focusing on adverse action on the basis of a personal characteristics or status of the producer, the second on certain protected actions by the covered producer, and the third focused on deception in contracting. AMS included these provisions based on the likelihood that conduct falling within one or more of these sections will stifle honest competition or exclude independent livestock producers, poultry growers, and swine contractors from the marketplace. Each provision could, however, have been implemented on a stand-alone basis without the others. Conduct that violates one provision is not dependent on protections put in place in other sections. For example, if a regulated entity discriminates against a producer on the basis of a protected class in an unduly prejudicial manner, AMS may enforce the regulation without alleging violations of retaliation or deception. These new provisions are written so that they are not mutually exclusive. Furthermore, the benefits of each provision of this rule are not diminished by the absence of a different provision. For example, the benefits of protecting producers against retaliation are not lost if the rule is held to fail to protect against deception or discrimination.
                    </P>
                    <P>AMS intends that the severability provision operate to the fullest extent possible. AMS recognizes that—to a limited extent—not all the language of the rule is severable. For example, to find undue prejudicial discrimination under “race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, or marital status, or age of the covered producer,” the prejudicial conduct must be “on the basis of” one of the specified protected bases. AMS recognizes that this causation requirement is not severable as it is integral to that specific provision of the rule.</P>
                    <P>However, AMS intends that all other portions and components of the rule may be severable without affecting the remaining portions of the rule, and that the rule remains workable and continues to serve the interests of the agency's policy goals. For instance, AMS intends that the invalidity or unenforceability of one of the rule's prohibited bases does not render the others invalid or unenforceable. The protected bases have different reasons for their appearance in the rule. For example, if the protected base of religion were found invalid or unenforceable, this does not negate the benefits of including protections for another protected base, like sex. Also, to further follow this example, the language in § 201.304(a)(1)(i) is severable from those included in the retaliation (§ 201.304(b)) and deception (§ 201.306) sections. Therefore, one or more provisions might be unenforceable as to an individual or a specific case, but AMS intends that the remaining provisions would still be enforced. Finally, if determining the necessity of an individual provision to the enforceability of its entire section, and the benefits of that section are still intact without an unenforceable provision, AMS would intend to retain the enforceable provisions.</P>

                    <P>AMS received 446 public submissions in response to the proposed rule. Numerous comments to the proposed rule expressed concerns that concentrated, vertically integrated markets expose producers to exclusion from the market on bases unrelated to the quality of their products or services and that the markets in which the commenters operate lack sufficient honesty, integrity, and fair dealing. In addition, numerous comments stated that, except for very narrow justified circumstances, there are no competitive benefits to these practices when operating within a market where producers are less able to compare, negotiate, or change business relationships.</P>
                    <P>Other commenters were critical of the proposed rule. Some commenters expressed disagreement with the need for the proposed rule, arguing that it is duplicative of the Act and existing regulations, while other commenters stated that the proposed rule's vagueness would make compliance a challenge. Other commenters argued that the proposed rule would result in costly litigation and recordkeeping burdens and exceeded AMS's authority under the Act.</P>

                        In § 201.302, AMS proposed to define

                         as any person engaged in the raising and caring for livestock by the producer or another person, whether the livestock is owned by the producer or by another person, but not an employee of the owner of the livestock. AMS proposed to add a new definition of 
                        <E T="03">covered producer</E>
                         to encompass livestock producers as defined in this section, along with swine production contract growers and poultry growers as defined in sec. 2(a) of the Act.

                         Several commenters noted the proposed definition of 
                        <E T="03">livestock producer</E>
                         could include individuals only tangentially related to livestock production, such as accountants working for feed yards, truck drivers hauling livestock owned by others, veterinarians, nutritionists, or consultants. The commenters contended the proposal opens the definition of 
                        <E T="03">livestock producer</E>
                         to an unlimited number of litigants beyond the scope of the Act.

                        Similarly, a meat industry trade association said AMS should withdraw or amend the definition of 
                        <E T="03">livestock producer</E>
                         because its vagueness potentially adds so many individuals to the covered producer umbrella as to be unworkable. Another association noted its confusion when reading the definition, given that the definition's wording explicitly excludes employees of the owner of livestock, but includes anyone who is not an employee of the owner of livestock that is engaged in raising or caring for livestock.

                         AMS is revising the definition of 
                        <E T="03">livestock producer.</E>
                         AMS intended that the term livestock producer be defined in a manner similar to other terms in the Act, so that the protections of the rule would fit violations that are described in this rulemaking. Under the final rule, 
                        <E T="03">livestock producer</E>
                         is defined as any person—except an employee of the livestock owner—engaged in the raising of and caring for livestock. As commenters noted, the proposed definition was vague and potentially confusing. The revised definition provides clarity by removing unnecessary and potentially confusing phrasing. In response to commenters' concerns that the term encompasses individuals only tangentially related to livestock production, AMS has revised 
                        <PRTPAGE P="16132"/>
                        the proposed definition to focus this final rule on the Agency's traditional role in protecting the producer to the fullest extent possible under the Act—including but not limited to production and marketing. To the extent that the producer is harmed through acts that the regulated entity takes against an employee acting as agent for the producer or another entity that the covered producer utilizes or relies on for production or marketing, the producer could still fully benefit from the protections of this final rule. Whether the non-producer parties could benefit from the protections of the Act may depend upon particular facts and circumstances.

                    <P>AMS proposed in §§ 201.304 and 201.306 to apply its prohibitions on undue prejudice, retaliation, and deceptive practices to swine contractors and live poultry dealers as defined in sec. 2(a) of the Act and to packers as defined in sec. 201 of the Act. Proposed § 201.304(a)(1) would prohibit prejudice, disadvantage, or the denial or reduction of market access by regulated entities against covered producers based on their status as “market vulnerable” producers. AMS requested comment on whether the prejudicial discrimination and retaliation provisions should be extended to all persons buying or selling meat and meat food products, including poultry, in markets subject to the Act.</P>

                         An agricultural advocacy organization expressed support for AMS's proposal to extend protections to all covered producers who experience retaliation by regulated entities.
                    </P>
                    <P>An agricultural advocacy organization said that if AMS adds aspects of regional concentration and aspects of contract growing arrangements, such as high debt load, to the definition of a market vulnerable individual, then the proposal to provide protection based on market vulnerable individual status is appropriate. This commenter noted that AMS's question regarding extension of the prejudicial discrimination and retaliation provisions highlights the need for a separate rule addressing enforcement of the Act's prohibition on undue preferences. According to this commenter, if AMS makes it clear that it intends to enforce the Act to stop companies from giving undue preferences to some sellers, everyone participating in these markets will have adequate protection.</P>
                    <P>
                        <E T="03">AMS Response:</E>
                         AMS appreciates the comments regarding a broader definition of MVI to include all those impacted by the abusive conditions aggravated by market concentration. AMS recognizes that producers face challenges because of consolidated market power, including from types of conduct this rule aims to address. One of the purposes of this rule is to address adverse impacts of concentrated markets by ensuring inclusive competition free of unjust discrimination on the basis of race, color, religion, national origin, sex, disability, or marital status, or age or because of the covered producer's status as a cooperative, as well as to protect against retaliation and deception.
                    </P>
                    <P>AMS underscores that the protections for cooperatives are intended, in part, to help producers gain market leverage in the face of concentrated markets. In 1922 Congress passed the Capper-Volstead Act providing legal protections for producers to collectively process, prepare for market, handle and market their products. Cooperatives enable smaller, disparate producers to band together, coordinate in ways that otherwise may not be permissible under the antitrust laws outside of a single company, and otherwise work together to obtain a better bargain from market counterparties with larger economic footprints. AMS will continue to work toward addressing problems associated with concentration through subsequent rulemaking. USDA is also utilizing other tools to address undesirable business practices born from market concentration that adversely impacts producers. USDA is investing $1 billion to support greater choice for producers through expanded local and regional processing capacity in meat and poultry. USDA has also announced enhancements to its antitrust enforcement partnerships, including investing in partnerships with DOJ through farmerfairness.gov and with more than 32 State attorneys general, updates to its meat and poultry labels that will better guard against misbranding that damages the signals that flow from consumers to producers, as well as other agency actions intended to address unfavorable behavior by regulated entities facilitated by concentration in the livestock industry.</P>
                    <P>However, addressing unjust discrimination solely on the basis of the size or indebtedness of the producer is outside the scope of this rule, and because of the complex economic implications of volume preferences and efficiencies, would be more appropriately considered in the context of a future update to undue preferences rules. In contrast, undue and unreasonable prejudice or disadvantage on the basis of the prohibited bases and protected activities adversely affects allocative efficiency and offers no competitive benefits. That is true irrespective of whether the unlawful conduct occurs in a concentrated market or not.</P>
                    <P>AMS has shifted away from its market vulnerable approach and has adopted a well-established standard in line with existing economic, civil rights, and other regulatory regimes that rely on protected bases for discrimination. Producers with high debt loads are not included in those well-established protections; therefore, AMS will not include them in its final rule.</P>

                    <P>AMS proposed new provisions in § 201.304(a) that would prohibit regulated entities from prejudicing, disadvantaging, or inhibiting market access, or otherwise taking adverse action against a livestock producer, swine production contract grower, or poultry grower based on the producer's status as a “market vulnerable individual” or as a cooperative.</P>
                    <HD SOURCE="HD3">i. Market Vulnerable Individual Approach</HD>
                    <P>
                        AMS proposed to prohibit prejudicing, disadvantaging, inhibiting market access, or otherwise taking adverse action against covered producers based on their status as a 
                        <E T="03">market vulnerable individual (MVI).</E>
                         It proposed to define that term as a person who is a member, or who a regulated entity perceives to be a member, of a group whose members have been subjected to, or are at heightened risk of, adverse treatment because of their identity as a member or perceived member of the group without regard to their individual qualities. A market vulnerable individual would include a company or organization where one or more of the principal owners, executives, or members would otherwise be a market vulnerable individual. When defining 
                        <E T="03">market vulnerable individual</E>
                         in its proposal, AMS listed a non-exhaustive list of protected classes that would be considered market vulnerable such as race, ethnicity, or sex or gender prejudices (including discrimination against an individual for being lesbian, gay, transgender, or queer), religion, disability, or age.
                    </P>
                    <P>
                        AMS requested comment on whether the regulatory protections provided by the prohibition on undue prejudices for market vulnerable individuals and cooperatives would assist those producers in overcoming barriers to reasonable treatment, or otherwise address prejudices or threats of prejudice in the marketplace. It further requested comment on whether specific 
                        <PRTPAGE P="16133"/>
                        groups should be named as market vulnerable individuals, whether AMS should identify defined protected classes, or whether AMS should use a “market vulnerable producer” approach, which extends broad antidiscrimination protections to any producer belonging to a group subjected to or at heightened risk of adverse treatment. In addition, it requested comment on whether it should delineate specific examples of groups that are market vulnerable, as well as supportive evidence regarding historical adverse treatment of such groups. Finally, it requested comment on whether the undue prejudices provision of the proposed rule provides sufficient protection regardless of the covered producer's type of business organization.

                         Several commenters indicated proposed § 201.304(a) would provide necessary protections, consistent with the Act, against packers and processors who leverage their market power to injure marginalized farmers. Farm bureaus and other agricultural advocacy organizations also indicated the rule would protect producers from certain prejudices, unjust discrimination, retaliation, and deceptive practices.
                    </P>
                    <P>Several commenters stated they preferred the market vulnerable producer approach to fighting discrimination over the traditional protected classes approach because it would allow for flexibility to address different markets and different forms of prejudice and discrimination that may develop. An agricultural and environmental organization stated the market vulnerable producer approach not only covers instances of discrimination based on protected characteristics such as race, national origin, sex, religion, gender identity, and disability, but can also apply to other forms of discrimination unique to livestock and poultry markets. This commenter said this approach is consistent with the Act, which prohibits “any” unjust discrimination, and “any” undue prejudice or disadvantage “in any respect whatsoever.” Several State attorneys general suggested that the proposed definition was preferable as proposed, without specifying traditional protected classes, because it would allow for flexibility among different markets and forms of prejudice or discrimination that may develop over time.</P>

                        Several agricultural advocacy organizations said poultry and cattle producers operating in regions with monopsony or oligopsony conditions should qualify as market-vulnerable individuals. Similarly, an academic or research institution sought to add producers operating in monopsony conditions to the definition. A commenter suggested AMS use the regional Herfindahl-Hirschman index to indicate the market vulnerable status of producers in a region. Some commenters cited heightened risk of adverse treatment as a rationale for considering these groups to be market vulnerable or noted that monopsony power has been legally relevant in cases under the Act and there is judicial precedent for acknowledging monopsonist power as a factor in adverse impacts to competition, while others said these groups meet the criteria laid out by AMS in the preamble to the proposed rule explaining why historically marginalized groups are likely to be vulnerable to market abuses.

                         The latter commenter provided detailed evidence that these groups met each of the criteria AMS identified: their relative “size, sales, and incomes;” their “exposure to concentrated market forces;” their having “fewer economic resources” to “counteract” adverse market structures; and their “isolation” from economic networks such as sources of supply, other producers, and distribution.

                    <P>Several commenters seeking protections for producers that are at increased risk of being disadvantaged due to highly concentrated regional markets cited Colorado cattle producers as an example, given the USDA has not publicly reported the State's fed cattle prices for several years because there are too few packers purchasing fed cattle in Colorado to overcome USDA confidentiality guidelines. Commenters noted, with few packers in the region, sellers in the region are vulnerable to unfair practices.</P>
                    <P>An agricultural advocacy association recommended that AMS expand the MVI definition to include covered producers whose geographic locations restrict their ability or willingness to sell and transport their livestock to two or fewer regulated entities. This commenter also said that it would be helpful for AMS to expand on and provide more “definite form” to the four socioeconomic factors presented in the rulemaking notice. The association reasoned that if producers can proactively demonstrate their status as market vulnerable, it would avoid the need for ad hoc microeconomic analyses or expert witnesses to make assessments on individual bases.</P>
                    <P>Several State attorneys general suggested AMS specifically address the vulnerability that small, rural farmers encounter due to their location or production size. The commenters stated small, rural farmers do not have enough local processors, and those processors give preference to packer-owned and contract livestock for the limited packing plant capacity available. An agricultural advocacy organization also said small, independent cattle producers meet many of the criteria for being considered market vulnerable, arguing for example that they are exposed to concentrated market forces because they do not receive forward contracting arrangements from packers; they are denied favorable bonus, financing, and risk sharing terms common with other arrangements; and they are required to sell their cattle to packers on at-will cash markets for lower aggregate compensation. Agricultural advocacy organizations also said independent cattle producers operating in cash-negotiated spot markets should be considered vulnerable because of their independent status. Other commenters recommended AMS expand market vulnerable individual status to include non-English speakers, people with limited education, producers in markets with limited buyers, and immigrant farmers.</P>
                    <P>Agricultural advocacy organizations recommended the definition of market vulnerable individual explicitly include, but not be limited to, race, color, national origin, religion, sex, sexual orientation, disability, age, marital status, family or parental status, income derived from a public assistance program, political beliefs, or gender identity. Commenters asserted individuals in each of these groups should not have to continually prove discrimination and prejudice against them based on the characteristic that makes them vulnerable in the market.</P>
                    <P>Agricultural advocacy organizations expressed support for including cooperatives in the prohibited bases under proposed § 201.304. These commenters recommended that AMS explain in the preamble to the final rule the relationship between the producer association protections under the Agricultural Fair Practices Act and the proposed new protections under the Act, noting regulated entities have unjustly discriminated against covered producers based on their membership in these cooperatives due to the increased market leverage these cooperatives or other producer associations provide.</P>
                    <P>
                        An individual commenter urged AMS to explicitly prohibit discrimination based on sexual orientation and gender identity for those who voluntarily disclose such status. The commenter 
                        <PRTPAGE P="16134"/>
                        stressed AMS should not require LGBTQ producers to disclose their sexual orientation or gender identity in conducting business, citing privacy, and security concerns. Other commenters noted sexual orientation is different from gender identity, so both should be listed individually in the rule.
                    </P>
                    <P>
                        Some agricultural and environmental advocacy organizations expressed support for AMS's flexible “market vulnerable individual” approach, but also expressed concern that the proposed rule would impose a difficult burden of proof on covered producers, requiring, for example, a producer alleging discrimination based on their status as a member of a historically marginalized group (
                        <E T="03">e.g.,</E>
                         a racial minority) to also demonstrate their status as a market vulnerable individual “in relevant markets.” Commenters indicated producers should not have to continually prove they are being discriminated against if they are members of a protected class or qualify as a market vulnerable individual. These commenters urged AMS to clarify the Act directly prohibits discrimination based on protected class status and to provide producers with guidance on how to demonstrate their market vulnerable status. Commenters recommended that AMS include in § 201.304 a non-exhaustive list of factors covered producers can rely on to demonstrate their market vulnerable status.
                    </P>
                    <P>Similarly, agricultural advocacy groups recommended that AMS clearly identify the types of individuals the agency would consider to be market vulnerable, and the methodology AMS will use to make this determination. A commenter specified producers who derive a substantial percentage of their income from their livestock or poultry operation are more vulnerable to unjust practices than those who derive a small percentage of their income from those operations. A commenter suggested that AMS develop a method to assess regional concentration levels using information regarding market share, Herfindahl-Hirschman index, and price reporting systems to allow producers to show they operate in a region that qualifies them as market vulnerable individuals.</P>
                    <P>An organization urged AMS to revise proposed § 201.304(a)(1) to clarify that the rule bans discriminatory conduct based on disparate treatment or disparate impact, not just discriminatory intent. According to the commenter, while secs. 202(a) and (b) of the Act clearly establish that the determinative factor for whether conduct constitutes a violation is its purpose or effects, the proposed language in § 201.304(a)(1) potentially requires a covered producer to prove discriminatory intent. The commenter said that, by describing prohibited conduct using the verb forms of “prejudice,” “disadvantage,” “inhibit market access,” and “take adverse action,” this language suggests the proposed rule would only prohibit actions motivated by a prohibited basis. Therefore, the commenter recommended that AMS revise this section to use language that parallels the text of sects. 202(a) and (b) in clearly distinguishing the actions of regulated entities from their discriminatory nature or effects.</P>
                    <P>
                        Some commenters who supported AMS's market vulnerable producer approach expressed concern that the proposed rule could place a heavy burden on producers to establish an intentional discrimination claim based on market vulnerable status, citing the DOJ, among others, in noting that successfully showing discriminatory intent can be extremely difficult.
                        <SU>170</SU>
                        <FTREF/>
                         According to the commenters, producers would have evidence of differential treatment, but they would not likely have evidence to show they were subject to adverse treatment because of their status as market vulnerable individuals. Therefore, these commenters urged AMS to require regulated entities to rebut a presumption of discriminatory intent once a producer demonstrates differential treatment. Specifically, the commenters recommended the final rule include provisions clarifying that, to prove an unlawful violation of § 201.304(a), producers must demonstrate that they meet the definition of a “market vulnerable individual” or are a member of a protected class, and that they were personally subject to disparate and adverse treatment. One commenter also said producers' burden here should include showing circumstantial facts plausibly suggesting a causal connection between their group identity and the treatment they received. The burden would then shift to the regulated entity to show that the producer's market-vulnerable status was not a motivating factor for its presumptively discriminatory conduct, and the same decision would have been made regardless of the producer's market vulnerable status. The commenters cited case law in asserting this burden-shifting approach is consistent with other antitrust and civil rights evidentiary frameworks developed by the courts to reduce the burden of proving discriminatory intent.

The commenter said the burden should then shift to the regulated entity to show that the challenged practice is necessary to achieve a substantial, legitimate, and nondiscriminatory interest which could not be served by another practice with a less discriminatory effect. The commenter also provided further details about what would constitute a discriminatory effect or a legitimate interest under this standard.

                        Some commenters expressed opposition to the proposed definition of market vulnerable individual on the basis that it was too vague. An association asserted the definition is “so vague that neither party may be able to figure out whether the contract grower is indeed a `market vulnerable individual.' ” Commenters said the proposed definition implicates the Due Process Clause, with commenters saying the definition as drafted is so open-

                        ended that it could potentially include any producer, thus giving processors inadequate notice of when they might be in danger of violating the proposed rule. Commenters suggested AMS intends for courts to flesh out the specifics on who the rule covers, noting this approach would lead to more uncertainty and confusion. Commenters also said the definition is vague because it incorporates inherently subjective concepts, such as whether a producer is a member of a group “whose members are at heightened risk of adverse treatment.” Commenters questioned what amount of risk constitutes “heightened risk.”
                    </P>
                    <P>Two cattle industry trade associations and a live poultry dealer contended that the ambiguity of the definition would create uncertainty for regulated entities when making market vulnerable-status determinations on a case-by-case basis, which could disincentivize bringing on new producers in the future. They argued that AMS could avoid this uncertainty if it introduced codified standards based on consistent immutable traits, such as protected classes.</P>
                    <P>Some commenters were opposed to explicitly including protected classes in the definition. A meat industry trade association noted that it can be difficult or impossible for regulated entities to ascertain all the demographic information for every producer they do business with to determine whether the producer they are contracting with is in a protected class and thus a market vulnerable individual. An agricultural association noted that regulated entities soliciting such demographic information could in and of itself give the appearance of discriminatory behavior.</P>

                         definition because they thought it would be too limiting. Two farm bureaus argued that it would create uncertainty for producers who do not meet the definition, and that protections should be available for anyone participating in the marketing of livestock. Other farm bureaus also suggested that

                         as the basis for the rule's prohibition on discrimination or undue or unreasonable prejudicial or disadvantageous action. AMS agrees that the term MVI may be too vague, ambiguous, and overly broad to serve as the prohibited basis for undue or unreasonable prejudice. Instead, this rule uses protected classes largely as defined by ECOA, plus disability and status as a cooperative, as the bases against which unjust discrimination or undue prejudice is prohibited because, as explained above in Section VI—Provisions of the Final Rule, this regulation incorporates the ECOA terms with respect to discrimination in the extension of credit because those terms reflect USDA policy against discrimination in conducted programs.

                         Protections against discrimination on these protected bases extend to all producers. AMS, incorporating feedback from producers and other stakeholders, decided to create its protected bases on the well-established ECOA standards, with some additions. Regarding the commenter's concern that regulated entities may not be aware of the demographic information of producers with whom they conduct business, in such cases AMS would not be able to prove discriminatory conduct because any adverse action taken against that producer could not have been on the basis of their status as a protected class.

                        AMS adopted several suggestions by commenters regarding the specific bases for protection against unjust discrimination. Principally, AMS's authority to clarify the protected bases stems from sec. 407 of the Act, which authorizes the Secretary to “make such rules, regulations and prescribed orders as may be necessary to carry out the provisions of this Act.” 
                        <SU>176</SU>
                        <FTREF/>
                         The Act has incorporated provisions of other law (such as the FTC Act and the Clayton Act). The Act is a remedial statute that prohibits unlawful discrimination. To inform the scope and bases of unlawful discrimination and prejudice under the Act in this rulemaking, AMS has looked to other civil rights laws, which aid in determining the scope of discrimination and prejudice that is unjust and undue. AMS concludes here that discrimination and prejudice on the bases set forth under this final rule inhibit the ability of all to participate in the market, and that the clarifications set forth in this final rule are necessary to protect all market participants from unjust discrimination and undue prejudice. Furthermore, AMS has considered available relevant references to support the determination. These include USDA's Statement on Conducted Programs 
                        <SU>177</SU>
                        <FTREF/>
                         and evidence of a general congressional policy found in ECOA that prohibits discrimination on the bases of race, color, religion, national origin, sex (including sexual orientation and gender identity), marital status, age, or disability. Additionally, AMS is including status of a covered producer as a cooperative as a prohibited basis of discrimination because Congress, through passage of the Capper-Volstead Act, has provided clear statutory support for cooperatives as an organizational form that allows farmers to achieve scale through coordination and thereby more effectively compete in agricultural markets and engage with other market participants. AMS is adopting the aforementioned specific bases, as opposed to MVI, because the specific prohibited bases offer clearer, more workable standards that will facilitate compliance by regulated entities and better enable producers to exercise their rights under the Act.

                    <P>The use of those terms comes with well-established jurisprudence in other contexts, such as ECOA, which incorporates the Act's enforcement provisions, appropriately applied in the context of livestock and poultry markets. Additionally, the status of covered producer as a cooperative was added to the list of protected classes against which discrimination is prohibited. The prohibition on discrimination covers cooperatives consistent with and in furtherance of the Agricultural Fair Practices Act. Cooperatives enable smaller producers' ability to balance concentrated economic power through their ability to coordinate and negotiate.</P>
                    <P>AMS will not include degrees of market concentration within particular geographic locations in its list of protected bases. Doing so would give rise to difficult questions around whether the government should restrict the ability of regulated entities to seek efficiency based on production volume, which is outside of the scope of this rule.</P>
                    <P>
                        Additionally, AMS will not include in its list of protected bases a size component for the same reasons that it is not incorporating market concentration or geographic location. Nor is AMS including a prohibition against discrimination in markets with limited buyers. In both cases, such a prohibition would likely result in an all-encompassing rule that would swallow this rule's intent to protect specific well-established classes and activities which are widely utilized across multiple 
                        <PRTPAGE P="16136"/>
                        economic and civil rights regulatory regimes to stop market exclusion and enable producers to realize the full value of their animals. AMS underscores that the agency is aware of and sensitive to the concerns that smaller producers face greater challenges in the face of concentrated markets, where, as commenters suggested, small rural farms are at a disadvantage when competing with larger operations in their sale of livestock to a limited number of packers.
                    </P>
                    <P>In this rule, AMS does not address questions of discrimination based on the type of contract a producer has with a regulated entity for the sale of their livestock. Considerations raised in that type of discrimination, revolving around how livestock is marketed, are different from the considerations undertaken in this rule around whether the producer's personal characteristics are a prohibited basis of unjust discrimination. Nonetheless, AMS is aware that some producers may be under pressure to enter forward contacts or AMAs and that this may limit their access to markets. AMS is considering other rules that may be more appropriate for addressing those concerns.</P>
                    <P>Additionally, AMS intends for non-English-speaking producers and immigrant producers to be covered under the prohibition on discrimination on the basis of national origin or, in some cases, race if they are facing discrimination on those bases. Therefore, AMS need not expressly include non-English speaking producers in this rule. However, people with limited education are not included as protected bases because enforcement of such discrimination offers certain practical challenges and is not well defined in other areas of law.</P>
                    <P>
                        In this final rule, AMS has expressly prohibited discrimination based on sexual orientation by adding that term as well as gender identity to the prohibited basis of sex. The Supreme Court in

                         AMS has included the term sex as part of its prohibition on discrimination.

Therefore, sexual orientation and transgender status are covered.

                    <P>Nor is disclosure a requirement for discrimination based on sex. If a regulated entity takes adverse action that amounts to undue prejudice against a person on the basis of sex, it is immaterial whether the decision is based on an accurate or inaccurate assessment of the actual gender or sexual orientation of the covered producer. In either instance, this prejudice is undue under the regulation.</P>
                    <P>In terms of concerns raised by commenters about the burden to establish a claim, producers will not have to prove their status as a market vulnerable individual as originally proposed as the bases of discrimination are now based on discrete types of protected classes. Therefore, as suggested by commenters responding to the proposed rule, AMS does not need to provide a non-exhaustive list of factors for covered producers to demonstrate their market vulnerable status.</P>
                    <P>
                        Furthermore, because market vulnerability is no longer a consideration when assessing violative conduct, AMS is not using market vulnerability as a basis for assessing whether unjust discrimination has occurred in violation of the Act. As noted above, this final rule will not address discrimination on the basis of geographical location, regional concentration, or size of a producer's operation because this rule is focused on prohibiting adverse actions on bases for which there are no pro-competitive benefits. Differences in treatment based on geographic location, regional concentration, or size of the producer's operation all raise more challenging tradeoffs with respect to competitive benefits. To the extent that a covered producer suffers discrimination on those bases, AMS encourages the covered producer to report the concern to PSD, including through the tips and complaints portal 
                        <E T="03">farmerfairness.gov,</E>
                         for consideration on a case-by-case basis under the Act.
                    </P>
                    <P>AMS is not establishing a formal burden-shifting framework in this rule, nor one specifically focused on discriminatory effects such as an analysis of disparate impact. Rather, AMS will leave the development of evidentiary proof to the facts and circumstances of specific cases and to the tribunals' processes and burdens for producing evidence. AMS has investigatory and enforcement capabilities to determine whether violative conduct has occurred under the Act. AMS's investigative powers are extensive and include the ability to examine regulated entities' records and compel testimony. AMS may investigate to determine whether a regulated entity's disparate treatment of a producer was on the basis of a protected class as specified in this regulation.</P>
                    <P>Moreover, as described in Section V—Changes from the Proposed Rule, subsection D—Retaliation Provisions, AMS changed “because of” to “based upon.” Paragraph (b)(1)'s prohibition as “based upon” is intended to be broader than “but for” causation and so capture when the protected characteristics or status are a material, or non-trivial, element of the decision to take an adverse action against a covered producer. AMS expects that fact-finding tribunals will establish the necessary processes for proving these elements, with an eye toward the protections for covered producers and for open, inclusive markets that this rule is designed to provide. AMS underscores that discriminatory intent is not an element of this final rule and need not be shown to establish a violation, for example, where the regulated entity cannot proffer a non-discriminatory business reason that fully justifies the adverse action, or where the producer can show that such reason offered was pretextual, a sham, or otherwise does not negate the presence of the prohibited bases as a material element of the action.</P>

                         This rule is designed to strengthen the regulatory protections afforded to producers by the Act. AMS intends to conduct education and outreach to producers to help them understand their rights under these acts. Additionally, greater access to specialized training and education could be helpful to stopping market exclusion of underserved producers. AMS and other USDA agencies conduct a range of programs to support producer education, with the goal of remedying market exclusion of underserved producers. However, providing specialized training oriented toward enabling members of historically disadvantaged groups to become more effective livestock producers is outside the scope of this rulemaking.

According to these commenters, the conduct addressed in the proposed rule is already prohibited under the Act and existing regulations, citing the “Undue and Unreasonable Preferences and Advantages Under the Packers and Stockyard Act” final rule (the 2020 Rule).

                         The commenters explained the 2020 Rule identifies factors for determining whether disparate treatment of similarly situated producers is justified. If the disparate treatment is not justified, it is likely to be deemed an undue or unreasonable preference. Commenters noted the proposed rule would prohibit several forms of disparate treatment of covered individuals, indicating proposed § 201.304(a)(2) would make it a violation for a regulated entity, in dealings with covered producers, to prejudice, disadvantage, inhibit market access, or otherwise take adverse action. Examples of prejudice or disadvantage specified in the proposed rule include offering less favorable contract terms than are customarily offered; refusing to deal; differential contract performance or enforcement; or termination or non-renewal of a contract. According to the commenters, these actions are already prohibited under § 201.211 because they are not justified based on cost savings, based on meeting a competitor's terms, or as a business decision.

                         AMS agrees with the commenters that the conduct at issue is prohibited under the Act and, in some circumstances, could be enforceable under existing rules and regulations. However, AMS disagrees with commenters who said this rule is duplicative of the 2020 Rule. In response to the proposed rulemaking that preceded the 2020 Rule,

                         AMS received numerous comments raising concerns regarding discriminatory and retaliatory practices; however, AMS stated that the 2020 Rule was published for the narrow purpose of establishing criteria to consider when assessing whether a violation of sec. 202(b)'s prohibition against undue preferences or unreasonable advantages occurred.

                    <P>The 2020 Rule established four criteria the Secretary will consider when determining whether conduct by packers, swine contractors or live poultry dealers represents an undue or unreasonable preference or advantage. Those criteria include whether the preference or advantage cannot be justified on the basis of a cost savings related to dealing with different producers, sellers, or growers; cannot be justified on the basis of meeting a competitor's prices; cannot be justified on the basis of meeting other terms offered by a competitor; and cannot be justified as a reasonable business decision. However, as set forth in the rule itself, the criteria are not exhaustive and not determinative. The rule offers limited guidance regarding how it is to be applied.</P>

                        The 2020 Rule did not include the prohibited bases of discrimination set forth in this rule because it asserted that they were undue prejudices, rather than undue preferences, which are distinct prohibitions in the statutory text.

                    <P>AMS is not aware of a separate Federal law or rule that would cover the circumstances outlined in this final rule. This rule sets forth how certain adverse actions by regulated entities give rise to unjust discrimination and prejudice that, on their face, are unjust and undue and undermine a competitive market. This rule addresses the unique and often difficult-to-prove discriminatory conduct that has long existed in the agricultural sector by prohibiting specific bases of prejudicial action. In doing so, AMS is clarifying the application of the Act, better empowering producers to protect themselves, and encouraging companies to adopt more robust compliance practices to snuff out prohibited conduct prohibited by the Act in its incipiency, before, in the aggregate, it can distort markets. In particular, this rule addresses the longstanding and often difficult-to-counter forms of exclusion that have plagued the agricultural sector for decades. AMS intends for this rule to support positive trends toward inclusivity in the marketplace. As noted above, all commenters, including industry commenters, affirmed that prejudices on the basis of race, color, religion, national origin, sex, age, disability, and similar bases have no place in today's modern agricultural markets.</P>
                    <P>Demographic information is seldom recorded in agricultural transactions; therefore, it is difficult to quantify discrimination, unlike in other sectors such as housing and banking. Furthermore, in highly concentrated agricultural markets with few minority participants, further defining the Act to include a list of prohibited bases of unjust discrimination helps ensure fair competition for all farmers. This rule will help all producers better understand their rights under the law and come forward when they recognize instances of unjust discrimination. This rule will help USDA to better enforce the Act. In addition, as AMS has determined not to use the market vulnerable individual approach in the final rule, commenter concerns that the definition for market vulnerable individual will lead to litigation are moot.</P>
                    <P>
                        AMS acknowledges one commenter's recommendation that AMS take action to reduce concentration in the meatpacking industry and create more packers, with the goal of facilitating greater market access for livestock and poultry operations. This recommendation was made out of skepticism that the rule would change 
                        <PRTPAGE P="16138"/>
                        conduct by regulated entities and substantially enhance market access for covered producers. While not directly addressing this specific recommendation, AMS is including a recordkeeping requirement to support evaluation of regulated entity compliance and thus facilitate effective enforcement of the statute. The USDA has also taken a number of steps to support small meat processors, including through hundreds of millions of dollars invested to support competition in the processing market.

                    <P>AMS asked about specific challenges or burdens regulated entities may face in complying with the undue prejudice provisions of the proposed rule. It also requested comment on how the undue prejudices provisions differ from existing policies, procedures, and practices of regulated entities.</P>

                         Industry commenters said the vague terms in the proposed rule present an additional challenge for compliance. Commenters cited unclearly defined terms such as “inhibit market access” and “adverse action,” saying they make it impossible for regulated entities to determine what constitutes a violation and how to comply with the proposed regulations. Similarly, commenters noted it is not clear how the regulated entity would determine whether contract terms are “less favorable,” or how contracts executed at different times, in different regions, or in different economic conditions would be compared.

                         “Inhibit market access” means excluding producers from livestock and poultry markets outright or erecting barriers to market access that prevent producers from earning the full value of their animals. AMS rejects the need to define “adverse action” because this would too greatly constrain the application of the regulation. Based on its regulatory experience, AMS believes regulated entities are fully aware of when their economic interactions with covered producers, including contracting, the operation of contracts, termination of contracts, or refusing to deal, result in adverse economic outcomes for producers. However, to provide greater clarity, the final rule provides greater specificity with respect to prohibited actions as set forth in § 201.304(a)(2), as described earlier.
                    </P>
                    <P>The scope of prohibited conduct regarding adverse actions is clarified by the shift from market vulnerable individual to membership in a protected class as the prohibited bases of unjust discrimination; the focus of the inquiry should be on those bases. If a regulated entity offers a covered producer less favorable contract terms principally or substantially because the covered producer belonged to one of the protected classes, it violates the law and this rule.</P>

                         AMS engaged in an extensive Tribal Consultation pursuant to USDA and Federal treaties governing U.S. relations with Indian Tribes. AMS's principal conclusion was that Tribal governments have important duties to serve their members that may require them to treat non-Tribal members less favorably. Accordingly, AMS has established a legitimate business justification as an exception to the prohibition of unjust discrimination against covered producers on the bases of protected classes (race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, marital status, age of the covered producer or the covered producer's status as a cooperative) when the regulated entity is a Federally-recognized Tribe, including its wholly or majority-owned entities, corporations, or Tribal organizations, that is performing Tribal governmental functions. The agency describes its rationale for creating this exception in greater detail above, as well as below under the Tribal Consultation section.

                         Agricultural advocacy organizations indicated this question relates to what is considered an “undue” preference. The commenters noted a program, practice, or policy that provides opportunities to producers who have been vulnerable to unfair market practices in the past may be a justified form of preference rather than an undue preference.

                         AMS takes note of the commenters' belief that a justified preference would likely apply in those circumstances and that this rule governs undue or unreasonable prejudices or disadvantages. As discussed above, the 2020 Rule establishes criteria for the Secretary to consider when assessing whether a preference is undue. To the extent that there may be situations where the 2020 Rule and this final rule would arguably both apply, AMS would take a facts-and-circumstances approach to decide which rule applies. Accordingly, AMS makes no change.

                         A group of State attorneys general and an academic institution expressed support for the proposed protection for cooperatives, noting these protections will ensure small farmers can continue to compete in the market. Agricultural advocacy organizations recommended AMS revise the reference to “cooperative” in proposed § 201.304(a)(1) to refer to “cooperatives or other association of producers” because many producer associations designed to give covered producers more leverage in the market are not structured as cooperatives, noting this recommended change is consistent with

                         AMS has included cooperatives as a class protected against prejudice or unjust discrimination because cooperatives are an important tool for smaller producers to countervail the market power of regulated entities, whether due to market concentration or the inherent power imbalance that exists in livestock supply chains between a small number of processors and a much larger number of producers. This inclusion of cooperatives as a protected class reaffirms the strong statutory authority Congress has provided cooperatives in agricultural markets, as manifested by its passage in of the Capper-Volstead Act, which permits producer cooperatives to collectively process, prepare for market, handle, and market their products.
                    </P>
                    <P>Adverse treatment at the hands of a regulated entity based on a grower exercising their right to join such an organization, including a cooperative or an association, is the exact conduct this provision addresses. However, the prohibition of regulated entities prejudicing a cooperative focuses on the cooperative's market interactions with the regulated entity compared to entities that are not cooperatives, and not on the formation or association of the cooperative itself.</P>
                    <P>Collectively, members of cooperatives are better able to gain access to markets, leverage negotiating power when dealing with regulated entities, and meet volume demands based on their ability to pool outputs. The rule supports covered producers in using procompetitive cooperatives to their fullest extent. This rule aims to ensure equal treatment of covered producers by regulated entities, regardless of whether or not a grower has exercised its right to join a grower organization or association. For these reasons, AMS has not changed § 201.304(a) to include “or other association of producers.”</P>
                    <P>AMS notes that many producer associations are designed to give their members certain benefits, including some ability to negotiate with regulated entities around certain outcomes in the market. However, cooperatives are the only group of agricultural producers with explicit ability to cooperate and contract collectively with regulated entities, which includes Federal antitrust law exemptions not enjoyed by other types of associations. Nonetheless, AMS notes the importance of covered producers forming associations that may offer benefits to their members outside of collective contracting. To that end, the final rule in § 201.304(b)(2)(iii) provides important new protections against retaliation for forming or joining an association.</P>

                         A cattle industry trade association and an agricultural advocacy organization proposed amending the prohibition of offering contract terms “less favorable than those generally or ordinarily offered” to reflect the fact that little is known about terms contained in forward contracts. They noted that it is unclear if the terms of forward contracts should be considered “generally or ordinarily offered” because, for example, atypical bonuses can be offered to a select number of preferred feedlots. If these bonuses are rarely offered, they may fall outside of the scope of “generally or ordinarily offered,” but would still disadvantage the other feedlots (market vulnerable individuals) that do not receive them. The commenters suggested AMS should instead compare specific terms of individual purchase agreements or contracts to determine violations.

                         Given the unique contract types in the cattle industry, AMS recognizes that certain premiums, discounts, and bonuses may not be “generally or ordinarily” offered. In this final rule, AMS is preserving the ability of regulated entities to be flexible in the types of contracts they offer to producers, with different producers having different contracts based on the particular quality and type of service provided for in the contract. Whether terms are generally or ordinarily offered is specific to the facts and circumstances of each case, including in comparison to similarly situated producers—a clarification which the final rule establishes. “Generally or ordinarily offered to similarly situated producers” is a fact-specific inquiry which looks to the contracting practices of the regulated entity, including how the regulated entity contracts for similar products or services with similar producers. While the rule does not guarantee any producer any particular contract terms, AMS underscores that the purpose of the rule is to prevent an adverse action based upon an unlawful basis. A refusal to offer a contract term

                         the producer's race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, or marital status, or age would weigh heavily in any analysis, as it inherently implies that the regulated entity is in the market to contract with those terms by others in the market. Such a circumstance is different than refusing to offer a contract because the producer is unable to meet special contract requirements.

                        AMS recognizes the existence of information asymmetry between regulated entities and covered producers, including in relation to what contract terms are commonly offered or not. AMS notes the availability of other tools to address that challenge, including new initiatives such as AMS's Cattle Contract Library Pilot, which provides disclosure into contract terms offered by packers with greater than 5 percent of the national market share, including disclosure of any contract specifications on financing, risk-sharing, and profit-sharing.

                         A cattle industry trade association and an agricultural advocacy organization recommended including in the prohibition on “refusing to deal” instances where a producer who ordinarily markets their livestock in the cash market is denied a bid unless they enter a forward contract with the regulated entity.

                         AMS is aware that market concentration in the cattle industry has had a negative effect on negotiated cash markets and on the ranchers who choose to deal exclusively in those markets, but the impact of thinning cash livestock markets on the ability of producers to use cash markets and freely enter forward contracts with regulated entities is outside the scope of this rulemaking. AMS will further consider the commenters' recommendations in the context of other rulemaking initiatives such as rules focused on particular species of livestock and evidentiary patterns of abusive conduct. AMS is making no further changes to the regulation as proposed in response to these comments.

                         Two farmers unions and several organizations generally supported the appropriateness of the list of specific prejudicial acts, but also recommended adding the phrase “including, but not limited to” to provide flexibility in evaluating future acts of discrimination or prejudice. An academic institution also endorsed the non-exhaustive list of specific actions provided in this section, suggesting the listed actions would reduce uncertainty in the industry and make this section of the rule easier to enforce.

                         This rule is not intended to limit AMS's ability to enforce the Act. Instead, the rule aims to better define the Agency's enforcement authority so that enforcement actions are more successful. AMS agrees with the commenters that listing specific prohibited prejudicial acts will aid enforcement efforts. The agency also agrees that such a list is meant to be exemplary, not exhaustive. To this end, “any other action that a reasonable covered producer would find materially adverse” has been added to § 201.204(a)(2) to indicate that a variety of other adverse actions done on a prohibited basis against covered producers may violate this section. The facts and circumstances of each case will be assessed in light of these provisions when determining whether the conduct in question violates the Act.

                         A swine industry trade association said that the specific “prejudicial or disadvantaging” acts listed, as well as the proposed rule's intimation that the list is “non-exhaustive,” would result in a vague and overbroad definition of prejudicial conduct. The commenter argued that terms such as “favorable” and “generally or ordinarily offered” vary with market conditions over time and would have to be ironed out in courts through costly litigation.

                         AMS has adequately described the type of conduct prohibited under this rule by expressly stating that undue prejudice and unjust discrimination on specified prohibited bases constitutes a violation under the Act.
                    </P>
                    <P>
                        AMS addressed concerns of vagueness by further defining conduct that is prejudicial or disadvantageous to producers in the final rule (as described in section V—Changes from the Proposed Rule). In particular, AMS has made a number of changes to provide additional clarity, specificity, and certainty to market participants relating to the list of adverse actions set forth in § 201.304(a)(2). In response to the commenter's concern that “generally or ordinarily offered” is a concept that may vary with market conditions over time, AMS revised the regulation to state “generally or ordinarily offered to 
                        <E T="03">similarly situated covered producers.</E>
                        ” Including this phrase in the final regulations provides more specificity with respect to the current market context in which the regulation would be applicable. Paragraph (a)(2)(vi) was added to limit the list to any other adverse action that a 
                        <E T="03">reasonable</E>
                         covered producer would find 
                        <E T="03">materially adverse.</E>
                         The final rule also adds two exceptions to the rule in new paragraph (a)(3), which provides further specificity to the rule by defining specific actions which are not considered prejudicial conduct under this rule.
                    </P>
                    <P>Nevertheless, AMS reads the statutory term “prejudicial” to be a broad term, that covers all acts that cause harm to covered producers on a prohibited basis with respect to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry. While the term “prejudicial” encompasses a broad range of conduct, it is not vague. This rule does not prohibit all harms that may be inflicted on covered producers by regulated entities, rather, only those prejudicial acts related to livestock, meat and poultry that occur on a prohibited basis.</P>

                         A cattle industry trade association said AMS should not prohibit the specific acts outlined in the rule because they are important tools that allow the free market to function. The commenter suggested that, while less favorable terms or contract terminations are unfavorable results for producers that experience them, they are important outcomes that incentivize producer innovation. If these specific acts are prohibited, the trade association argued, regulated entities would need to resort to “vanilla” standardized contracts that would degrade consumer outcomes and impair superior producers' profit opportunities.

                         AMS rejects the argument that discrimination on the basis of race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, marital status, age of the covered producer, or the covered producer's status as a cooperative, or retaliation is a free market value. Engaging in that unjust discriminatory conduct would exclude participants from the market, rather than encourage them.
                    </P>
                    <P>Moreover, the members of the trade association were mistaken even with respect to the original proposal protecting market vulnerable individuals. Regulated entities are free to use contracting tools to develop incentives. But a tool used to unduly prejudice the vulnerable does not incentivize; it oppresses. Any other conclusion is contrary to the plain meaning of the Act. This rule aims to create an inclusive, fair, and equal environment for farmers and ranchers to conduct business by preventing instances of unjust discrimination and undue prejudice. The key concept here is that there shall be no discrimination on the protected bases regarding the offering of “general and ordinary” contract terms. AMS concludes that the benefits of protecting farmers and ranchers from plainly unjustly discriminatory treatment outweigh the hypothetical prediction that such regulations will hamper efficiency or innovation. Inclusive markets breed innovation and efficiencies; they do not undermine them.</P>

                         An academic or research institution proposed adding a new specific action that would encompass “information disclosure.” The commenter defined information disclosure as failing to provide information materially relevant to a producer's operation while providing that information to one or more other producers. The commenter highlighted information asymmetry as a major fairness issue in livestock markets and suggested such asymmetry can heighten monopsony or oligopsony conditions. The commenter also cited the former Grain Inspection, Packers and Stockyards Administration's (GIPSA's) inclusion of information asymmetry in a 2010 proposed rule (the 2010 GIPSA Rule),
                        <SU>187</SU>
                        <FTREF/>
                         which defined undue or unreasonable prejudice or disadvantage as “whether information regarding acquiring, handling, processing, and quality of livestock is disclosed to all producers when it is disclosed to one or more producers.” The commenter encouraged AMS to use similar language in its final rule.

                         AMS is concerned about the negative impact information asymmetry, and the subsequent lack of transparency, has on producers. Information asymmetry could very well be used as a means of unjust discrimination if regulated entities preference certain producers over others through the information they choose to disclose. Such selective disclosure of information could cause those producers from whom information was withheld by regulated entities to lose out economically to those producers that received the information.
                    </P>
                    <P>In the final rule, AMS has added paragraph (a)(2)(vi) to address any other action that a reasonably covered producer would find materially adverse. If a covered producer can show they are materially harmed by information asymmetry, they will have a recourse under this rule. Additionally, the prejudicial act of differential contract performance or enforcement (§ 204(a)(2)(iii)) covers selective information disclosure in many circumstances. Withholding materially relevant information from a contractee that it previously made available to the contractee or which it makes generally or ordinarily available as part of its contract performance to other contractees is de facto differential contract performance or enforcement. A producer is likely to operate in a less-than-optimal manner regarding financial renumeration when the regulated entity it is contracting with has withheld materially relevant information that has been disclosed to other contractees. Such behavior will thus lead to differential contract performance or enforcement.</P>
                    <P>AMS has not adopted the wide-ranging proposal on information asymmetry from the 2010 GIPSA Rule because it could inhibit the ability for regulated entities to select trusted partners with whom to engage in more complex, value-added production that may require specialized cooperation and information sharing.</P>
                    <P>Addressing information asymmetry and improving transparency in interactions between covered producers and regulated entities is a focus of AMS and will continue to be a priority in rulemaking. AMS made no further changes to the provisions regarding undue prejudices in response to this comment.</P>

                         This rule prohibits regulated entities from denying covered producers access to the purchase or sale of livestock on equitable terms, including through AMAs, on account of one of the rule's protected bases.

                        <E T="03">AMS Response:</E>
                         This rule addresses undue prejudices that can exclude covered producers from the marketplace. As such, the rule focuses on terms that a regulated entity offers which are 
                        <E T="03">less favorable</E>
                         to those 
                        <E T="03">generally or ordinarily</E>
                         offered. To the extent that a regulated entity generally, commonly, or ordinarily offers bonuses, cost-sharing, and cost-plus contracts, then the denial of those terms to covered producers on the grounds of belonging to a protected class is covered by this rule as forms of differential contract terms. It is not, however, AMS's experience that those terms are generally, commonly, or ordinarily offered to producers, and based on the reporting in AMS's Cattle Contracts Library Pilot, are rarely if ever offered.
                        <SU>189</SU>
                        <FTREF/>
                         The rule does not prevent regulated entities from offering preferences to some producers, in particular for reasons relating to their choices in types of business relationships or how they incentivize quality of products or services delivered to them. This rule does not take a position on whether bonuses, cost-sharing, and cost-plus contracts may give rise to concerns of unfairness, undue preferences, or other concerns that are outside the scope of this rule.

                         AMS agrees that contract prices commonly reflect a range of differences in circumstances between the contracting parties. To the extent that those prices reflect differences in product quality or service being provided, including transportation and delivery, parties are free to set prices in contracts as they wish. This rule focuses on exclusion or adverse actions on only the enumerated prohibited bases. Accordingly, AMS made no changes to the rule based on the comment.

                         A cattle industry trade association and agricultural advocacy organizations argued that legitimate business reason defenses should not be allowed because it would weaken the Act's purpose and allow continued harm to producers. A swine industry trade association and an industry company argued that exceptions should be provided for legitimate business reasons, and that AMS should: (1) provide clear examples delineating between legitimate and illegitimate forms of differential treatments, and (2) provide clarity on whose burden it is to prove that an act meets the legitimate business reason exception. The company asserted that without such an exception there would be frivolous litigation where regulated entities would have to defend legitimate behavior such as canceling contracts with producers who are found to have animal welfare violations. A plant worker agreed that legitimate business exceptions should apply, and pointed to California employment law's affirmative defense, which serves as a complete defense if a policy alleged to cause a disparate impact is found to be efficient for the business.
                    </P>
                    <P>Commenters expressed concern that the proposed rule did not define legitimate business justification. Commenters expressed concern that the proposed rule fails to provide the industry with specific exceptions or justifications for disparate treatment of producers, stating there are multiple reasons why different (less favorable) terms may be offered to certain producers and not others, and that these reasons are not insidious in nature but instead a result of market forces and other nondiscriminatory factors. Additionally, several poultry industry commenters noted that AMS suggests in the preamble a legitimate business reason may justify disparate treatment, yet it never explains what constitutes a legitimate business reason. Several poultry industry commenters provided examples of reasonable business decisions that would result in differential treatment and may violate the proposed rule as written despite their reasonableness. These commenters urged AMS to add regulatory text similar to that in § 201.211 to expressly protect reasonable business conduct and specify how a company would demonstrate that an action was based on a reasonable business decision. The commenters also said that, due to the complicated nature of business relationships, business decisions should be presumed reasonable unless proven otherwise. A poultry industry trade association provided examples of complex fact patterns and asked, given each situation, how the regulated entity could demonstrate actions were taken for appropriate reasons.</P>
                    <P>An industry association contended proposed § 201.304(a) would eliminate the statutory requirement in 7 U.S.C. 192 that adverse actions against a market vulnerable individual are only prohibited if they are undue or unreasonable. The commenter noted the statute only prohibits “undue or unreasonable” advantages and disadvantages, meaning advantages or disadvantages that lack a reasonable business purpose. However, the commenter pointed out that, under the proposed rule, if the action is “adverse” and it impacts a market vulnerable individual, even if it was based on a legitimate business reason, the regulated entity would be in violation of the regulations. The commenter also noted that enforcing contract rights is often “adverse against” the other party, but “adverse” does not mean inappropriate or unfair. Commenters cautioned the proposed rule may result in regulated entities giving all producers the same contract terms to avoid litigation, which would eliminate the market competition the Act was intended to protect.</P>

                         AMS agrees with commenters that legitimate business justifications exist for disparate treatment of producers. AMS does not agree, however, that there are many legitimate business justifications for prejudice or disadvantage on the basis of race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, or marital status, or age of the covered producer. The rule seeks to prevent regulated entities from discriminating against producers on specific prohibited bases, retaliating against producers for exercising certain protected rights, and deceiving producers in the procurement of livestock. It does not limit the ability of regulated entities to make other business decisions, as long as they comply with the Act in that they are not unduly prejudicial or unjustly discriminatory. This includes terminating contracts for violating contractual provisions such as animal welfare policies. To clarify what types of conduct are allowed, the final rule delineates two specific legitimate justifications for discriminatory action by regulated entities against producers. Discriminatory conduct by a regulated entity falling in one of these categories is not prejudicial: (1) the regulated entity is fulfilling a religious commitment related to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry, and (2) a Federally-recognized Tribe, including its wholly or majority-owned entities, corporations, or Tribal organizations, that is performing Tribal governmental functions.

                    <P>
                        AMS is adopting the religious exception to recognize the important role ritual slaughter plays in certain religious traditions. AMS is also recognizing the important roles that Tribes play as governmental units and operators of economic enterprises. In those governmental activities, as interpreted by the Supreme Court as well as Federal laws governing Tribal affairs, Tribes may require the flexibility to only purchase livestock from or sell meat to their members. AMS believes that actions following these two 
                        <PRTPAGE P="16143"/>
                        principles do not amount to undue or unreasonable prejudice, disadvantage, inhibition of market access, or adverse action. Through its review of public comments and based on its experience, AMS finds these are the only two appropriate exemptions from the rule's broad prohibition against undue and unreasonable prejudices and disadvantages.
                    </P>
                    <P>
                        AMS underscores that, in this rule, legitimate justification only applies to whether adverse actions against covered producers on a prohibited basis are still permissible. Where the adverse action is 
                        <E T="03">not</E>
                         on a prohibited basis or was not differential in its treatment of producers on the prohibited basis, then the question of there being a legitimate justification is not relevant.

To the contrary, AMS finds that prejudice, disadvantage, or discrimination on the prohibited bases set forth in this final rule to be per se unjust, undue, and unreasonable.

                         Several organizations and an academic institution expressed support for the proposed rule's retaliation provisions, saying that poultry and meat companies take advantage of unbalanced power to create a climate in which farmers and ranchers fear retaliation for exposing unfair industry practices. One organization cited a recent anonymous survey of contract growers it had conducted, in which multiple respondents described experiencing retaliation from integrators and said integrators regularly terminate the contracts of farmers who engage in whistleblowing activities, leaving them with substantial debt tied up in specialized, single-use structures built as a condition of their contractual agreements.

                    <P>An agricultural advocacy organization said § 201.304(b) as proposed fits easily within the scope of the Act's prohibitions on undue prejudice and unjust discrimination, closes a key enforcement gap, and represents a solid first step toward prohibiting unfair retaliation.

The commenter said regulated entities have deeply embedded retaliation into their business practices, leaving producers too intimidated to expose industry abuses. The commenter also cautioned that meat processors and live poultry dealers may attempt to find novel ways to retaliate against producers that do not directly violate the proposed rule, suggesting AMS broaden the range of protected producer activities and of prohibited retaliatory behavior.</P>

This commenter also said cattle and pork producers take similar actions against producers who expose problematic practices. A meat industry trade association said the proposed rule would ensure that farmers and ranchers have access to a public forum necessary for open, transparent communication. Numerous individuals indicated support for the proposed rule's protections against retaliation, with many saying the proposed rule would allow farmers to engage in whistleblowing actions without facing repercussions and would thus promote consumer, environmental, and animal welfare concerns.</P>

                         AMS takes note of the commenters' support for the usefulness of the provisions. AMS designed the provision on retaliation to cover the core activities of being a producer—that is, activities are essential or unavoidable for producers in terms of their abilities to enjoy the full extent of their bargain and protect their economic rights. AMS notes that the provision that protects a covered producer who communicates or cooperates “with a person for the purposes of improving production or marketing of livestock or poultry” is broad. This covers many different scenarios not specifically named in this rule. AMS expects the retaliation provision of this rule to provide a significant measure of protection to covered producers against prohibited conduct, and likewise provide opportunity for redress, both to stop particularized harmful conduct, and keep it from persisting and causing greater harm. AMS chose this list of prohibited retaliatory practices based on conduct the agency identified as most commonly relevant to regulated entities' practices that exclude or penalize producers. This list is based on AMS's experience fielding complaints from producers, from its expertise in the operation of the livestock and poultry markets and practices of market participants, as well as the numerous comments to this rule that identified similar practices. AMS acknowledges there may be other forms of retaliation that would violate the Act that are not specifically delineated under this rulemaking. Prosecutorial discretion will determine what conduct is in fact retaliatory based on the facts and circumstances of each case. AMS made no further changes in response to these comments.

                         An agricultural advocacy organization suggested AMS consider further developing the enforcement procedures for the retaliation provisions, as well as the evidentiary burdens associated with complainants and defendants. The commenter specifically recommended that AMS establish a burden-shifting approach which would establish that, once a complainant has made a

                         showing that a covered producer was subjected to retaliation after engaging in protected activities, the regulated entity would have to show by clear and convincing evidence that they would have taken the same action in the absence of the producer's participation in protected activities. Shifting the burden to the regulated entity (who has the best access to proof about the underlying facts) once the complainant has met an initial threshold would reflect a public policy position against

                         As described in Section V—Changes from the Proposed Rule, subsection D—Retaliation Provisions, AMS changed “because of” to “based upon.” Paragraph (b)(1)'s prohibition as “based upon” is intended to be broader than “but for” causation and so capture when the protected characteristics or status are a material, or non-trivial, element of the decision to take an adverse action against a covered producer. AMS expects that fact-finding tribunals will establish the necessary processes for proving these elements. Moreover, AMS expects that evidentiary presentation may often follow those approaches to proving retaliation in other contexts as a function of the natural course of any litigation. AMS underscores that the rule is designed to protect producers' ability to engage in such covered activities, with the clarity provided by the rule specifically designed to assist producers in identifying and acting in a manner to effectuate their rights. AMS further notes that the prohibition on adverse actions taken on pretext are prohibited under 9 CFR 201.306 as established by this rule.

                         The rule as written protects covered producers from retaliation for protected activities, which include the assertion of contractual rights. Violation disclosures made within the chain of command or as part of the covered producer's contractual duties fall within the operation of the contract between the covered producer and the regulated entity, and as such may be expected to be covered by the rule. Accordingly, AMS made no change to the rule.

                         Compared to general criteria and interpretive guidance, this rule provides greater clarity, specificity, and certainty to how the Act applies, which will facilitate higher levels of compliance by regulated entities with the Act, broader enforcement of its provisions by AMS, and more informed producers, who will be in a better position to assert their rights established by the Act. Additionally, unlike § 201.211, this rule focuses on preventing undue prejudices and disadvantages and does not focus on preferential treatment that is not discriminatory. Accordingly, AMS made no change to the rule.

                         AMS believes that some degree of generality is necessary to capture the range of conduct that could give rise to a violation of the rule. However, the rule is not designed to prohibit every instance where a regulated entity's contracting decisions are unfavorable to a covered producer. For example, the rule would not apply where a regulated entity was engaged in unrelated business around the purchase or sale of farmland, or where a regulated entity chose for unrelated reasons not to continue a contract in the course of a covered producer's attempts to sell its farm. AMS believes that the wording of proposed § 201.304(b)(3)(iv)—“[i]nterference in farm sale transactions or contracts with third parties”—is appropriately specific to prohibit regulated entities from 
                        <E T="03">retaliating</E>
                         against covered producers for engaging in protected activities. This is because the focus of an AMS inquiry would be to determine the reason for the interference. AMS would determine whether a regulated entity interfered in a farm sale or third party contracting; if such interference occurred, whether it was harmful to the covered producer; and whether the interference occurred because the covered producer engaged in protected activity. Additionally, in response to this comment, AMS has included explanatory language in the retaliation section (Section VI.C—Provisions of the Final Rule, Retaliation) discussing the adverse effects that interference with the transfer of farm real estate by a regulated entity has on producers.

                         Proposed § 201.204(b)(2)(iii) provided broad protection against retaliation for a producer to form or join a producer or grower association and would cover all aspects of associations and cooperatives relevant to the business of livestock and poultry. Further, AMS acknowledges the importance of the freedom of association generally but underscores that the protections of the Act have limits. The Act is designed to protect covered producers in the business of livestock and poultry. AMS is not in a position to know or evaluate the full range of associations that individuals who are producers may join, and it would not be appropriate for AMS to be involved in encouraging or discouraging such associational activities, including whether regulated entities should be required to do business with covered producers that engage in those activities. Some associational activities unrelated to the business of livestock and poultry may expose regulated entities to reputational or other risks in the marketplace.

                         This rule is intended to establish broad prohibitions against retaliatory activities that in AMS's experience have significantly inhibited producers' ability to freely compete and secure the full value of their products and services. AMS agrees that intimidation or coercion that would dissuade or coerce covered producers from engaging in the prohibited activities are covered under “retaliate or otherwise take an adverse action against a covered producer.” In particular, intimidating or coercive conduct that credibly threatens retaliation prohibited by this rule would rise to the level of actionable adverse conduct under by this rule—which the Agency underscores further through its addition of Paragraph (b)(3)(iii) and (v) under the list of adverse actions. For example, if a regulated entity were to communicate to a producer stating, “if we were you, we would not report to the government” with the implication that the regulated entity might not renew their contract on favorable terms, AMS views this as a form of prohibited retaliatory conduct in its incipiency that this rule is intended to stop.

An agricultural advocacy organization noted that the freedom to refrain from associating is as important as the freedom to associate and represents the other side of the same coin.

                         AMS agrees that protected activities include the decision not to participate in such an activity. Based on its experience regulating the livestock sector, covered producers may be coerced by regulated entities to participate in associational activities or contact the government on regulatory and policy matters even when they may not agree. As recently as AMS's proposal on “Transparency in Poultry Growing Contracts and Tournaments,” covered producers reported to AMS potentially coercive pressure by regulated entities on poultry growers to oppose the regulation. AMS also notes commenter statements that regulated entities have pressured and may continue to pressure covered producers to join associations to support industry stances with which they disagree. Accordingly, AMS has added § 201.304(b)(2)(ii) and revised § 201.304(b)(2)(iii) to clarify that the decision not to participate in the protected activities, respectively, of engaging in a voluntary communication with the government or of forming or joining an association are also covered by the rule's protections against retaliation.

                         AMS agrees with the commenter and intends that the rule should include protections for communications with any of those entities, including any committee or member official of those entities. In this final rule, AMS is aligning the use of the terms “government agency, court, or legislature” and simplifying the language to “government entity or official.” This change ensures that protected communications may occur with any of the three branches of governments and with individual government officials, including committees and members of a legislature. As proposed, the rule did not limit its protection to communication with the Federal government. By using the words “government entity or official,” the rule's plain language applies equally to communications with all levels of government—Federal, State, Tribal, and local—with respect to the matters indicated.

                         A group of State attorneys general said the proposed rule may inadvertently leave out protections for farmers who communicate their concerns directly to regulated entities, suggesting AMS target this gap by expanding § 201.304(b)(2)(vii) (§ 201.304(b)(2)(ii) in the proposed rule) to include notification by a producer to the regulated entity of a potential breach of contract. An academic institution said protected activities should include the assertion of any civil right held by the producer, to the full extent feasible within the scope of AMS's authority. The attorneys general said that, while the proposed rule covers rights granted under the Act, the proposed rule, and contract rights, it does not encompass other rights a producer may have, such as whistleblower or other rights conferred by Federal or State law. An organization said the proposed rule should clarify, given the imbalance of power in contracting, that producers cannot waive the rights covered by this provision by any agreement, policy form, or condition of employment, including by a pre-dispute arbitration agreement.

                         With respect to the suggestion that AMS revise § 201.304(b)(2)(vii) to include notification by a producer to the regulated entity of a potential breach of contract, the regulation as proposed protects producers' right to assert their contract rights, their rights under 9 CFR 201, and their rights under the Act. The language of this protection necessarily encompasses the act of communicating with regulated entities, including to prevent a potential breach of contract; otherwise, a producer would be unable to exercise their contract rights. Accordingly, there is no need to add further notifications by the producer to the regulated entities to the list of protected activities in § 201.304(b)(2).
                    </P>
                    <P>With respect to the assertion of any civil right, the protected activities enumerated in § 201.304(b)(2) were chosen because of their nexus to the business relationship between regulated entities and covered producers with respect to livestock, meats, meat food products, livestock products in unmanufactured form, or live poultry. To the extent that a contract between a regulated entity and a covered producer includes representations and warranties, including implied ones, relating to either party's compliance with other Federal or State laws, such as labor, health, and safety practices, this provision would extend to communications relating thereto. AMS notes that the protection afforded in § 201.304(b)(2)(vi) covers supporting or participating as a witness in any proceeding with the regulated entity. The rule does not change any additional protections that may be provided under other Federal or State anti-retaliation laws.</P>
                    <P>With respect to the request that AMS revise the rule to clarify that producers cannot waive rights covered by the rule, AMS believes that the commentors are mistaken about the structure of the Act and its regulations. AMS enforces this rule. Irrespective of any agreement between the contracting parties, AMS does not waive its responsibilities to enforce the Act. The Act and regulatory scheme are designed to vindicate the public interest in fair and honest markets. Thus, AMS regularly brings its own enforcement actions to sanction companies that violate the provisions of the Act, irrespective of the contracting parties' waivers of liability. A regulated entity that seeks a waiver from a producer through undue prejudice, retaliation or deception still violates the general provisions of the Act by using a deceptive, unfair, or unjustly discriminatory practice.</P>
                    <P>To the extent that individuals waive their rights, AMS points the commenter to existing regulations at 9 CFR 201.218, which limit the use of mandatory arbitration clauses, as mandated by Congress in the 2008 Farm Bill (Pub. L. 110-246). Specifically, those regulations require that the regulated entity offer the producer or grower a specific disclosure regarding the ability to decline a mandatory arbitration clause and indicate that failure to accept or decline the arbitration clause will be treated as if the clause is declined. Additionally, the regulation sets out criteria governing the reasonableness of the arbitration clause. Arbitration is a procedural forum that some parties may utilize to adjudicate substantive rights; arbitration clauses cannot waive substantive rights under contracts or the Act.</P>
                    <P>Accordingly, AMS is making no changes to the rule in response to these comments.</P>

Accordingly, AMS is making no changes to the rule in response to this comment. However, as the commenter notes, asserting rights under a contract is not a protected activity under the Act and it is not the intention of AMS to incorrectly assert this false presumption through this rulemaking.

This commenter further suggested large agricultural companies would do well to appreciate the benefits of producer participation in such organizations, such as opportunities to make progress on solving problems, develop industry consensuses for presenting to government, and hear the perspectives of members with opposing views. An individual said producer organizations often act as a barrier between individual producers and consumers, and the proposed rule would prevent producer organizations from retaliating against producers who try to change this behavior and provide truthful information about the conditions under which their products are grown or raised.

                         AMS believes that the act of forming or joining an association clearly encompasses the act of communicating about the formation or joining, including examining the decision whether to form or join an association. All such activities are covered by the final rule. Therefore, AMS does not make any changes to the rule on those grounds.

                    <P>Additionally, AMS appreciates that producer organizations may at times be at odds with their producer members. However, producer organizations are not considered regulated entities under this rulemaking, and thus retaliatory conduct at the hands of such organizations is not covered. Producers have the choice to join or separate from such organizations based on their individual feelings surrounding the costs and benefits such membership brings. If producers feel as though their membership of an organization is serving as a barrier between them and consumers, thus preventing transparency regarding growing conditions, producers may find it advantageous to disassociate. Often producers do not have this luxury in their relationship with packers and integrators due to their reliance on these regulated entities and the absence of alternative buyers due to regional concentration.</P>

                         AMS disagrees with the commenter's assertion. The regulation protects the covered producer from retaliation for forming or joining an association or choosing not to join an association. It does not protect the covered producer from other acts that the association may take. This rule does not condone, for example, associational behaviors that violate the Sherman Act. Nor does this rule otherwise restrict the relationship between regulated entities and covered producers, whether the association may support or condemn particular acts or practices. Nor, additionally, does it suggest that the mere fact of forming or joining an association garner absolute protection from adverse actions by the regulated entity which are unrelated to forming or joining an association. Therefore, AMS has made no changes to the regulation as proposed.

                         AMS fully intends to protect many of the communications a producer makes in the ordinary course of business, so that the producer may freely operate in the market without fear of retaliation. Therefore, the regulation protects lawful communications and cannot, and does not seek to, absolve covered producers from unlawful communications. Section 201.304(b)(2) makes this clear by underscoring that the producers' activities are protected from retaliation only to the extent they are not otherwise in violation of Federal antitrust and other relevant laws. Furthermore, to find a violation of § 201.304(b)(2) there must be a causal connection between the regulated entity's behavior and a producer's protected communications, including where a regulated entity makes a threat that would reasonably dissuade the covered producer from engaging in the protected activity. AMS made no changes in response to this comment.

This protection encompasses participation, assistance, or intent to participate in any investigation of a possible violation of the Act.

                        to the proposed list of protected activities would not receive protection under the rule, arguing that retaliation of any kind against producers exercising their lawful rights qualifies as unjust discrimination and an unreasonable prejudice under the plain meaning of the Act. The commenter urged AMS to instead include the following catch-all provision to protect covered producers from retaliation against other lawful conduct in service of livestock production and marketing:
                    </P>
                    <P>“(viii) A covered producer engages in any lawful conduct for the purpose of improving production or marketing of livestock or poultry.”</P>
                    <P>A farmers union said AMS should broaden the grievance-sharing activities producers can participate in to give producers more protection from retaliation.</P>
                    <P>An agricultural advocacy organization said AMS should protect the ability of producers to freely associate with other farmers and other organizations, including using social media or other communication platforms.</P>
                    <P>An agricultural and environmental organization said AMS should expand the list of protected activities to include situations in which producers maintain their status as independent participants on open markets, refusing to enter into forward contracts or other contractual agreements that set future price or performance at the regulated entity's request. According to the commenter, producers who resist entering into forward contracts and AMAs often face retaliation, and therefore the final rule should protect them. The commenter recommended AMS add another paragraph to § 201.304(b)(2) as follows:</P>
                    <P>(vii) A covered producer refuses to sell livestock or poultry through forward contracts, AMAs, or similar contractual arrangements, opting instead to engage in open market sales.</P>
                    <P>An organization said lawful communications protected under the proposed rule should also include situations where a complainant provides information regarding conduct that they reasonably believe violates the Act or is about to do so. The commenter said that, because most people are not experts on their rights under the Act, the proposed rule should establish that complainants do not need to mention specific violations and that, as with similar corporate anti-retaliation measures, they do not need more than a subjective, good faith belief that the conduct at issue violates the Act. The commenter also said AMS should allow these complaints in any language and by means including in person, in writing, and by email.</P>

                         AMS appreciates and shares the commenters' viewpoint that retaliation is a serious concern in the livestock and poultry industry. AMS has attempted to craft this regulation to respond to the most common and clearly defined forms of retaliation in the form of prohibited unjust discrimination on the basis of protected activities. The regulation does not seek to define every prohibited activity, as the Act may limit unjust discrimination in circumstances not foreseen by this final rule. If covered producers believe they have suffered a form of unjust discrimination that is prohibited by the Act, they should report that to AMS.

                    <P>AMS acknowledges a commenter's concern regarding some covered producers' interest in not utilizing forward contracting for the sale of livestock.

                        AMS underscores that, to obtain the protection of this regulation, the producer need not engage in any particular form of the activity, such as quoting a precise regulatory section to assert an Act right. The focus will be on the substance of the producer's activities, and a good faith effort to assert an Act or contractual right is still protected from retaliation

                         AMS takes note of the commenters' recommendations of expanded protections for activities related to communication and cooperation. AMS believes that the commentators' concerns are largely addressed in the rule, which protects lawful communications with government agencies or other persons for the purpose of improving the production or marketing of livestock or poultry, exploring a possible business relationship, or supporting proceedings under the Act against a regulated entity, among other protected activities. The regulatory text provides broad coverage for these activities in § 201.304(b)(2)(iv) through (vi), without limitation. These communications are protected because they enhance producers' ability to receive protection under existing laws, improve the production process, and facilitate enforcement of contracts in ensuring producers receive their bargain for exchange. Communications unrelated to those purposes are outside the scope of this regulation.
                    </P>
                    <P>Whether social media communications are covered will depend on the protected activity in question and the particulars of the social media forum in question. Whether a public post by a covered producer about treatment by a regulated entity that the covered producer asserts to be in violation of the Act or is otherwise harmful to the producer may depend on the facts and circumstances of the post. For example, to the extent that the producer is testifying to Congress or courts regarding unfair treatment and the social media post simply refers to the testimony or describes the same material, then, for example, such a post would likely be protected, depending on the full scope of the facts and circumstances.</P>
                    <P>Similarly, if the social media post is part of an effort to share information with other producers for the improvement of production or marketing or is part of an effort to form an association or engage in cooperative activities, that would likely be protected under this rule as well since the rule is agnostic as to the form of the communications between producers. However, AMS notes that the activities protected under this rule are covered to the extent that these activities are not otherwise prohibited by Federal, State, or Tribal law. For example, the rule does not provide an exemption from defamation laws.</P>
                    <P>Nor does this rule attempt to preempt freedoms of the press. Whether a communication with a reporter or public investigation organization is covered will depend upon the facts and circumstances. The inquiry would need to balance the important role that freedom of the press plays in maintaining market integrity with legitimate expectations by a regulated entity of good faith behavior by a producer under a contract. Relevant questions include whether the communication was part of a factual effort to assist the reporter in understanding and reporting on asserted violations of law and regulation and whether the producer provided any confidential business information to the investigator or otherwise exposed the regulated entity to commercial risk or reputational damage unrelated to the violation in question. Also potentially relevant, in some circumstances, may be whether the producer has exhausted other avenues for resolving any dispute and also the extent to which the regulated entity has a reputation recognized in the market for retaliation which would otherwise place the producer in fear of asserting rights even with the presence of this rule.</P>
                    <P>The rule does not provide unlimited license for producers to damage the reputation of regulated entities. A social media post principally functioning as a threatening or coercive public communication is unlikely to be covered, absent other extenuating facts and circumstances. AMS underscores that the rule is intended to facilitate lawful communication and the exercise of lawful economic rights by covered producers, and the promotion of competitive markets and markets with integrity. That goal is most effectively served by enabling producers to exercise contractual and legal freedoms, communicate with government, other producers, and competitor firms for the purposes set forth in this rule. Therefore, AMS makes no changes to the rule in response to these comments.</P>

                         Several organizations asked AMS to broaden these protections to include communications and negotiations with any entity for the purpose of exploring a business relationship or alternative business model. According to these commenters, producers may want to explore alternative uses for industry livestock or poultry-raising infrastructure or add an additional type of agriculture to their operation. Several commenters said that while they recognize that producers who transition outside of the industry would no longer be covered under the Act or subject to many of the retaliatory actions covered by the proposed rule, they believe extending this protection is necessary so producers can fully explore all potential business opportunities without worrying about punishment if they do decide to retain their current business relationship.

                         The purpose of the provision is to preserve and promote the competitive position of the covered producer, and as such to ensure that the covered producer is not discouraged from seeking competitive alternatives by a regulated entity's retaliation. Paragraph (b)(2)(v) protects a covered producer's ability to communicate, negotiate, or contract with a regulated entity, another covered producer, another commercial entity, or consultant, for the purposes of exploring or entering into a business relationship. The Act is intended to ensure maximal competitive flexibility for covered producers. It may be the case that producers wish to explore a business opportunity by communicating, negotiating, or contracting with a consultant about forming a cooperative or, with a commercial intermediary such as an exchange or auction, or with another covered producer or commercial entity that may not yet be 
                        <PRTPAGE P="16150"/>
                        a regulated entity but intends to engage in meat or poultry processing. It may also be the case that producers wish to negotiate with other covered producers for the purpose of jointly investing in a business venture such as a slaughter facility. Accordingly, AMS has amended the regulation to indicate that the final rule provides protection for a covered producer who communicates, negotiates, or contracts with a regulated entity, another commercial entity, another covered producer, or a relevant consultant, for the purpose of exploring a business relationship. AMS concludes that a consultant either works to benefit another commercial entity or works to benefit the covered producer, and so would be covered by the provision.

                    <P>AMS requested comment on whether the proposed list of retaliatory actions should include a catch-all clause, such as “offering contract terms that are less favorable than those generally or ordinarily offered.”</P>

                        <E T="03">Comment:</E>
                         Several organizations indicated support for a catch-all provision. The commenters said they would be in favor of prohibiting the retaliatory offering of less favorable contract terms as AMS suggested in the preamble to the proposed rule. Commenters said this addition would recognize the importance of contracts as a retaliatory weapon because of their effect on producers' financial well-being and would avoid a potential loophole for the proposed rule's prohibition on retaliatory termination or non-renewal of contracts and refusals to deal. One commenter suggested that AMS include a new provision saying “offering unfavorable contract terms that otherwise affect reprisal” or “offering contract terms that are less favorable than those generally or ordinarily offered” is a prohibited action. However, several commenters recommended that AMS also introduce a second, broader catch-all provision to ensure that regulated entities cannot simply formulate new ways to retaliate against producers for engaging in protected activities. These commenters suggested that AMS add the following regulatory text to § 201.304(b)(3) to achieve both aims:

                        <E T="03">AMS Response:</E>
                         AMS elected not to introduce a provision prohibiting the “offering of contract terms that are less favorable than those generally or ordinarily offered” to its list of prohibited retaliatory actions as requested by a commenter because retaliation is principally focused on protecting producers from adverse actions by regulated entities in which they already have establish or recurring contractual relationships. The list of adverse actions in paragraph (b)(3) was designed to provide examples of the most common forms of retaliation as discrimination addressed by this rule. However, the proposed rule was intended and drafted broadly so as to ensure producers can engage in protected activities at all times and with all regulated entities in the marketplace. As described in Section V—Changes from the Proposed Rule, the final rule provides more specificity. Yet the final rule would still protect a producer against adverse treatment by a regulated entity which may be seeking to chill those activities across the marketplace—such as forming a producer association or asserting rights under the Act with other regulated entities—through the clarification that other actions that a reasonable covered producers would find materially adverse.
                    </P>
                    <P>Additionally, AMS accepts the commenters' critique that the proposed regulatory text was insufficiently specific to provide clarity regarding when regulated entities could and could not take adverse actions against covered producers. In particular, AMS is concerned that the proposed contours regarding refusals to deal and non-renewals offer regulated entities too great a latitude to engage in retaliation, because a regulated entity could, in theory, satisfy the proposed rule by simply offering highly unfavorable terms to the covered producer—which it could not do if the agency prohibited “offering of contract terms that are less favorable than those generally or ordinarily offered.” That is not, however, the intent of the regulation. Rather, it is to ensure that covered producers, in whatever circumstance they enjoy, do not suffer retaliation for effectuating their rights under the Act.</P>
                    <P>Accordingly, in the final rule, AMS has amended the provision to add several clarifying details. First, the final rule clarifies that requiring modifications or only offering to renew contracts on terms less favorable than those enjoyed by the covered producer is a violation where it occurs because the covered producer engaged in protected activities. This provision covers any adverse change to the covered producer's terms to provide maximum flexibility to the covered producer to exercise protected rights regardless of the particular circumstances. Second, the final rule clarifies that a refusal to deal with covered producers would be triggered where the regulated entity fails to offer terms generally or ordinarily offered to other similarly situated covered producers. This provision does not guarantee the covered producer the most favorable contract terms in the market, but simply those that the covered producer would generally or ordinarily offer to other similarly situated covered producers that had not engaged in protected activities, which could include the situation previously enjoyed by the covered producer prior to having engaged in the protected activity. Such a provision is necessary because covered producers may enter or exit the market at different times, and during that period may engage in protected activities for which a regulated entity may attempt to retaliate. Together, AMS believes that these modifications cover the most common circumstances that covered producers may encounter in their business dealings in which regulated entities may attempt to exact retaliation.</P>
                    <P>
                        AMS is not including the level of detail sought by some commenters regarding the specific form of retaliation. This rule is intended to provide protections for adverse actions against a covered producer based upon the protected activity (including threats intended to chill engaging in that activity). Any inquiry should focus on those bases, rather than on the particular form of the discriminatory harm. AMS recognizes that unfavorable 
                        <PRTPAGE P="16151"/>
                        contractual terms can cover a wide range of elements of a contractual relationship, such as prices, formulas, premiums or discounts, transportation provisions, delivery dates, duration, the required number of animals, arrangements such as financing, investment requirements or incentives, and other contractual specifications, among other terms and conditions. Such unfavorable terms may have direct financial impacts but may also have indirect financial impacts, such as reputational impacts which adversely affect the covered producer's ability to conduct business in the marketplace. Providing further detail in the regulatory text is not necessary to enforce the rule. It is not practical to name all the different ways a malicious actor could find to retaliate. The rule is intended to capture as fully as possible the difference between a serious contract offer and an offer that has the practical intent to retaliate.
                    </P>
                    <P>Additionally, AMS confirms that when a regulated entity claims that modification or renewal of a contract on less favorable terms is common with similarly situated producers for reasons unrelated to any exercise of protected activities, AMS will not automatically consider the less favorable modification or renewal a violation of this particular rule. AMS will, however, review modification and renewal and will carefully examine the regulated entity's justifications. Even outside of retaliation, unilateral modification of existing contracts has been a violation of the Act. The Act considers it an unfair and deceptive practice to modify an existing contract to either extend the time for payment or reduce the full price agreed upon at delivery. Moreover, contract modification has been a deceptive practice where the terms offered publicly were privately disavowed.</P>

In the final rule, AMS has added paragraph (b)(3)(iv) to address any other adverse action that a reasonable covered producer would find materially adverse. This is intended to focus on material harms to covered producers, including threats, based on the protected activities. However, AMS is not including the level of detail sought by some commenters regarding the specific forms of retaliation, because providing further detail in the regulatory text is not necessary to enforce the rule. There are too many possibilities to encompass every possible retaliatory action in a single rulemaking. The Agency prefers the general prohibitions because their simplicity reaches a broad array of unlawful retaliatory activities, including the ones the commenter raises.

                         In this final rule, AMS has made a number of changes, outlined above in Section V—Changes from the Proposed Rule, to provide additional clarity, specificity, and certainty to market participants. These include switching prohibited conduct in § 201.304(b)(3) from an exemplary list to a specific list of covered items. AMS rejects the general assertion that the provisions on retaliation are vague, ambiguous, or non-exhaustive. To the contrary, the final rule sets forth specific activities that are protected (§ 201.304(b)(2)) and specific conduct (§ 201.304(b)(3)) that would constitute retaliation if it were done because of the producer engaging the protected activities. As described above under Section V—Changes from the Proposed Rule, these included a range of further clarifications to the specific conduct. Notably, the inexhaustive list under paragraph (b)(3) has been refined, with paragraph (b)(3)(v) added to limit the list to any other adverse action that a

                        The activities protected by this final rule each constitute an exercise of basic freedoms necessary and essential to maintain a free and competitive market—freedoms such as exercising contractual and legal rights, seeking recourse through governmental channels, forming cooperatives or associations relating to the business of livestock and poultry, and being a witness in court. Most regulated entities assert that retaliation for engaging in these types of activities is not a common practice in the industry. AMS finds that factually questionable, given the level of complaints and concerns expressed by producers over the years, including

                        experience in response to producers' participation in hearings on competition by USDA and the DOJ in 2010. But to the extent that regulated entities stand by that position, then there should be little risk to regulated entities from litigation on the grounds of the activities protected in this rule. Regardless, AMS can identify no competitive benefits to adverse actions against covered producers for engaging in the activities protected by this final rule and can identify no genuine risks to contractual freedoms or ability to legitimately innovate from the activities protected by this final rule.

                         AMS has not identified any competitive benefits to adverse actions against covered producers for their having engaged in any of the protected activities set forth in this final rule. Accordingly, AMS has not provided any exemptions to the prohibition on retaliation against covered producers. If a regulated entity claims it has taken an adverse action against a covered producer for reasons unrelated to the producer's exercise of rights protected by this final rule, it becomes a factual question of proof. The agency has the burden of showing that the regulated entity violated the rule by taking covered adverse actions against a producer or grower wholly or in part because of the producer's or grower's exercise of a protected right under the rule. Any such determination will turn heavily on the particular facts and circumstances of any claim. This factual determination is not a question of whether a legitimate business reason existed to engage in the retaliation; rather it is a question of whether a violation occurred at all. In some cases, it may be possible that the regulated entity, including in the form of its agent interacting with the covered producer, is genuinely not aware of the protected activity by the covered producer (including not having constructive knowledge, being willfully blind, or grossly negligent in its affairs), the adverse action would not constitute a violation. AMS does not expect, and indeed does not encourage, the regulated entity to engage in any monitoring activities to attempt to make itself aware of when covered producers may be engaging in these activities. In fact, the purpose of the rule is the opposite, and were AMS to identify a regulated entity engaging in any such monitoring program, it would likely view such activities as being in violation of this regulation owing to their likely effect of intimidating producers.

                         A swine industry trade association said the proposed rule would allow producers who engage in common conduct, such as joining a cooperative or asserting their rights under a contract, to claim that a regulated entity engaged in retaliation by terminating a contract or giving differential treatment to a producer. A poultry industry trade association and several live poultry dealers said the retaliation provisions create a presumption that all grower protected activities are legitimate, which could open the door to strategically planned actions by poor performing growers designed to trigger these protections and would lead to especially severe risks if a grower has committed animal welfare violations.

                         AMS rejects the assertion that the rule would permit or encourage gaming by producers to avoid accountability for poor performance or violations of animal welfare guidelines. This final rule clearly specifies that the adverse action must be taken

                         the producer participating in such protected activities. The mere coincidence, or correlation, between a producer joining an association or reporting to the government and then experiencing an adverse action is not enough for a violation. There must be evidence showing the adverse action taken by a regulated entity was in response to the producer engaging in a protected activity for a violation to be exist.

                    <P>Additionally, AMS rejects the comment that the regulated entity would face a burden because it would not know which protected activities the producer has engaged in.

                         A poultry industry trade association and several live poultry dealers said the proposed rule also does not provide clarity regarding cooperative activity: live poultry dealers would still need to select which specific growers to contract with, choose where to place birds, and evaluate and approve housing and other grow-out specifications even if growers form cooperatives, but the proposed rule does not provide guidance on whether a regulated entity making these decisions might be considered to be engaging in retaliation.

                         A cooperative is a well understood legal status under the Co-Operative Marketing Associations (Capper-Volstead) Act of 1922 (Pub. L. 67-146) and protected by the Agricultural Fair Practice Act of 1967, which the proposed and final rule have both referenced. Generally, a cooperative is an organization established by individuals to provide themselves with goods and services or to produce and dispose of the products of their labor. The property of a cooperative, including the means of production and distribution, are typically owned in common. The final rule covers activities inherent in the planning and organization of a cooperative.
                    </P>
                    <P>AMS also rejects the comment that live poultry dealers would still need to determine how to treat particular growers when dealing with a cooperative. Cooperatives are independent entities, and the live poultry dealer would enter in a contract with the cooperative as a whole, rather than with any individual grower. The terms of the general contract would govern the relationship between the live poultry dealer and the cooperative. Generally, a cooperative is an organization established by individuals to provide themselves with goods and services or to produce and dispose of the products of their labor. The property of a cooperative, including the means of production and distribution, are typically owned in common. This rule prohibits live poultry dealers from discrimination against a cooperative because it is a cooperative or from retaliating against producers for forming a cooperative. Because a cooperative is an entity, a regulated entity cannot assert that they are dealing with a cooperative but then limit the agreement to individuals.</P>

                         This rule will not create exceptions to existing laws governing the sharing of information between members of associations and cooperatives. Information sharing by associations remains governed by the Federal antitrust laws and other relevant laws. Certain conduct by cooperatives is exempt from the Federal antitrust laws. This rule does not change whether these activities are lawful and protected, or prohibited, under Federal law. AMS makes no changes in response to this comment.

                         A whistleblower advocacy organization suggested several changes to expand the proposed rule's coverage. First, it recommended AMS extend the proposed rule's anti-retaliation protection to all natural or legal persons who provide information they reasonably believe is evidence of a violation of the Act or who refuse to take action they reasonably believe would violate the Act. According to the commenter, protected persons should include, but not be limited to, employees of meatpackers and integrators reporting violations of the Act; employees, contractors, and subcontractors of protected farmers or ranchers; and associates and relatives of protected persons or entities. Second, the commenter said that AMS should clarify language in the proposed rule stating that it does not protect farmers and ranchers acting in contravention of the Act from retaliation. According to the commenter, the final rule should exclude from protection only individuals acting without express or implied direction from the covered entity or its agent, and who deliberately and willfully cause a violation of any requirement relating to any violation or alleged violation under the Act. The commenter said this clarification would ensure that live poultry dealers cannot use this provision to attack farmers under broiler production contracts who engage in whistleblowing. According to this commenter, these contractors are subject to extreme corporate control that denies them the right to act under their own agency, so it would not be fair to exclude them from the protections against retaliation based on actions they could not control.
                    </P>
                    <P>This commenter also said that, because farmers are often unfamiliar with protections that apply to their exposure of industry wrongdoing, USDA must make efforts to share information about producer rights and company responsibilities at the beginning of the contractual relationship as well as throughout the engagement. The commenter suggested that AMS host educational programming about rights under the Act and develop language-appropriate educational material. The commenter urged USDA and DOJ to continue to offer anonymous protected disclosures through their joint portal and be transparent about subsequent regulatory and enforcement activity, saying most producers prefer to make reports anonymously or through another party to avoid retaliation.</P>

                         In this rule, AMS is principally focused on providing robust protections for covered producers participating in the market. Accordingly, AMS has not amended the regulatory text to extend the rule's coverage to all natural or legal persons who provide information regarding perceived violations of the Act or who refuse to take action they believe would violate the Act. AMS has, however, revised the regulatory text of § 201.304(b)(2)(i) to extend the coverage from a covered producer's communication “with a government agency” to communication “with a government entity or official” and from “petitions for redress of grievances before a court, legislature, or government agency” to “petitioning a government entity or official for redress of grievances.” AMS believes that this change ensures that protected communications may occur with any of the three branches of the Federal government and with individual government officials, including committees or members of a legislature. The regulation applies equally to communications with all levels of government—Federal, State, and local—with respect to the matters indicated.
                    </P>
                    <P>Furthermore, AMS is sympathetic to and broadly in agreement with the commenter's perspective that covered producers should not be required to understand the precise contours of the Act to exert their protected activity rights, and that they should be enjoyed heightened protection when acting at the express or implied direction of a regulated entity. Regulated entities have no motive to purposefully induce producers to commit unlawful acts. If a regulated entity induces criminal activity, irrespective of retaliation, this inducement may be deceptive within the meaning of the Act.</P>
                    <P>
                        AMS appreciates the commenter's advocacy regarding the need for continuing USDA-sponsored education regarding producer rights and company responsibilities under the Act. AMS is taking steps to increase producer education and outreach, including, for example, establishing the

                        Other commenters supported the proposed recordkeeping requirements, but suggested AMS should require regulated entities to maintain additional specific records. A cattle industry trade association said AMS should require retention of any records that include specific terms (including prices paid) of purchase agreements or contracts, as well as any methodologies used to calculate premiums or discounts paid to producers. This commenter argued that such records would enable AMS to evaluate differential treatment. An agricultural advocacy organization made a similar suggestion for regulated entities to maintain income/payment formulas and pre-contract discussions with producers as part of their recordkeeping obligations.

                         AMS takes note of the commenters' support for the usefulness of the provisions. With respect to the request that AMS revise the rule to identify specific records that regulated entities must retain, AMS notes that the regulation as proposed provides flexibility for a regulated entity to retain any records relevant to its compliance with § 201.304(c), including records not specifically referenced in the regulation. Under sec. 401 of the Act, regulated entities are already required to maintain the accounts, records, and memoranda necessary to fully and correctly disclose all transactions involved in their business. USDA's implementing regulations can be found at 9 CFR 201.94, 201.95, and 203.4. Existing regulations under part 201 require regulated entities to give the Secretary “any information concerning the business . . .” (§ 201.94) and provide authorized representatives of the Secretary access to their place of business to examine records pertaining to the business (§ 201.95). Section 203.4 regulates the types of records that must be kept by regulated entities and the timelines for disposal of these records. As part of its enforcement capabilities under sec. 401 of the Act, AMS can inspect the records of regulated entities to review detailed information related to purchases and ensure that regulated entities are in compliance. Because these records are already required under existing law, AMS made no further changes in response to the comments.

                         A poultry industry trade association argued that the proposed recordkeeping regulation—as written—is not appropriate because it is vague and does not make clear that it only requires integrators to maintain records relevant to proposed § 201.304(a) and (b). The trade association contended that the rule should make explicit that, if a regulated entity does not maintain records relevant to those respective proposals, no recordkeeping is required. The commenter also recommended exempting privileged communications or attorney work product from the recordkeeping requirement.

                         AMS disagrees with the commenter's view that the regulation as proposed does not make clear that regulated entities are only required to maintain records relevant to proposed § 201.304(a) and (b): the regulation as proposed specifically stated that a regulated entity “shall retain all records relevant to its compliance with paragraphs (a) and (b) of this section.” Further, AMS does not believe it necessary to specify that certain records do not need to be retained if they are irrelevant because the regulatory text states explicitly that the recordkeeping requirement applies only to records relevant to a regulated entity's compliance with this section. Under the Act and existing PSD regulations, regulated entities are required to keep records pertaining to their business. To comply with the proposed regulation, a regulated entity must retain all records relevant to its compliance with § 201.304(a) and (b) for no less than five years from the date of record creation. Lastly, AMS does not believe that adding an exemption for privileged communication, such as attorney work product, is necessary because attorney work product is already protected from disclosure under current law. Therefore, AMS makes no changes to the rule in response to this comment.

                         Several commenters expressed concern that the proposed recordkeeping requirement would not be sufficient to ensure compliance. One organization argued that AMS should require regulated entities to proactively identify and record the basis of differential treatment (

                         differences in prices paid) among producers. An academic or research institution concurred, suggesting that any differential treatment in price or contract terms should be justified by regulated entities in their records.
                    </P>
                    <P>An agricultural and environmental organization proposed regulated entities should be subject to an Annual Compliance Report to AMS that requires a detailed list of all their transactions. This list would include, specifically: (1) an anonymized list of producers the regulated entity did business with; (2) terms offered to producer during contract negotiations; (3) terms entered with producer and whether these terms differ with similarly situated producers; (4) prices paid to producers and methodology for the price; (5) whether AMAs were used; and 6) accounts of all instances of the regulated entity's refusal to deal with a producer and justification for the refusal. The commenter argued that it will be difficult for producers or AMS to prove violations of proposed § 201.304(a) without these detailed disclosures.</P>
                    <P>An agricultural advocacy organization proposed requiring regulated entities to report to AMS the contract terms and payments made to producers, as well as producer demographic information necessary to determine which producers are market vulnerable individuals. The commenter argued this was necessary to put the burden of enforcement of the new rule on AMS and regulated entities rather than covered producers. This commenter also suggested requiring regulated entities to use a uniform recordkeeping system that tracks and reports “relevant data” to allow AMS to monitor for potential differential treatment or discrimination. This commenter likened the proposed system to the Home Mortgage Disclosure Act, which allows regulators to use data from regulated entities to ensure compliance with fair housing laws.</P>

                         AMS is making no changes to the rule as proposed based on this comment. AMS believes that the regulation as proposed permits flexibility for regulated entities to determine which records best demonstrate compliance with § 201.304. Such an approach is appropriate, given that this rule regulates the poultry, cattle, and swine industries, and that regulated entities vary in size and in the nature of their business operations. Regulated entities may have an existing recordkeeping system in place that is suited to their industry, size, or business operation. The proposed regulation's flexibility regarding the types of records that must be kept will ensure that the array of regulated entities covered by this rule can choose the method of compliance most relevant to their circumstances; the proposed regulation's specification that a regulated entity must retain all records relevant to their compliance with § 201.304(a) and (b) will aid in PSD's enforcement of paragraphs (a) and (b). As noted above, under sec. 401 of the Act, AMS is authorized to conduct compliance inspections, which may include examination of information related to differences in purchases and prices. AMS also has the power under sec. 6 of the FTC Act to require reports from corporations on a case-by-case basis. The additional reporting requirements suggested by commenters are outside the scope of this rulemaking, but AMS reserves the right to consider those approaches in future rulemakings.

                         As noted in the response above, this rule regulates a wide array of entities. Regulated entities may have an existing recordkeeping system in place that is suited to their industry, size, or business operation. Also as noted above, existing regulations and the Act require regulated entities to keep records of their business operations, subject to AMS compliance investigations. The regulation as proposed provides the flexibility for regulated entities to keep the types of records they deem appropriate to demonstrate their compliance with § 201.304, rather than requiring all regulated entities to keep the same set of records that may not be relevant to how they run their businesses. Paragraph (c)(2) provides a non-exhaustive list of examples of the types of records that may be relevant for a regulated entity to demonstrate compliance with § 201.304(a) and (b). AMS is making no changes to the rule as proposed based on this comment.

                         A poultry industry trade association and several live poultry dealers said that the proposed recordkeeping rule was overly broad, such that regulated entities would need to document and maintain every document related to interactions with producers (such as emails, visits, or notes from calls or meetings). The commenters raised concerns that this obligation would impose an overwhelming administrative burden and exorbitant compliance costs on regulated entities, which would be compounded by the 5-year record maintenance requirement. They suggested reducing the requirement period to two years. An agricultural association shared these concerns, in particular around the possibility that communications with any person about potentially entering into a contract may be deemed relevant under the rule and that, as such communications could be directed at any employee, a regulated entity could have to maintain records of all communications with its employees for a period of five years. This commenter said, if USDA interprets the recordkeeping requirements in this broad manner, would impose a particular burden on smaller entities subject to the recordkeeping requirement since these entities lack the administrative or IT infrastructure necessary to comply. A legal foundation also posited that the recordkeeping proposal would impose significant costs on regulated entities and—to reduce their burden—urged AMS to impose a warrant requirement before requiring disclosure of records.

                         AMS is making no changes to the regulation as proposed. The recordkeeping requirement in this rule is not new. PSD currently has recordkeeping authority through the Act and its existing regulations, including sec. 401 of the Act, and 9 CFR 201.94, 201.95, and 203.4. Further, AMS subject matter experts—economists and supervisors with years of experience in AMS's PSD conducting inspections and compliance reviews—have estimated the recordkeeping costs associated with this rule to be relatively low. They have estimated that recordkeeping costs would be correlated with the size of the regulated entity, with the assumption that the hour burden would be highest for the largest entities. Therefore, at the highest end of the spectrum, AMS has estimated that annual recordkeeping compliance costs for the largest regulated entities would average of 4 hours of administrative assistant time and 1.5 hours of time each for managers, attorneys, and information technology staff in the first year. Thereafter, for the largest entities, annual recordkeeping compliance costs would average 3 hours per year of administrative assistant time, 1.5 hours per year of manager and attorney time, and 1.00 hour of time from information technology staff. As stated previously, AMS estimates that the hour burden would decrease proportionate to the size of the entity. AMS also notes that some firms might not have any records to store, while other firms may already store relevant records and may have no new costs associated with this rule. It also notes that the list of suggested records in § 201.304(c)(2) is illustrative and that regulated entities are not required to document and maintain all of these records. Therefore, AMS estimates that the compliance costs associated with this rule will be relatively low and, as these costs are likely to vary in proportion to the size of the regulated entity, smaller entities are unlikely to face particular burdens. The objective of the recordkeeping requirement is to support USDA monitoring efforts as well as to preserve the flexibility of allowing regulated entities to decide how best to comply with the rule. It is incumbent upon regulated entities to decide which records are relevant for rule compliance.

                        AMS is also declining to revise the regulation to limit the record retention requirement to two years. AMS believes that requiring that records be retained for five years from their creation date will enable the agency to monitor the evolution of compliance practices over time in this area and will ensure that records are available for what may be complex evidentiary cases. AMS will not be adding a warrant requirement to the rule at this time because the Agency already has jurisdiction under the Act to request documents concerning a regulated entity's business and therefore no warrant is required to do so under governing law.

                         Commenters including a group of State attorneys general, several organizations, and an academic institution indicated support for the deceptive practices provisions, with one commenter saying the provisions would clarify the duties of regulated entities to engage in honesty and market integrity.

                    <P>Two agricultural advocacy organizations recommended that, in addition to the four broad prohibitions on behavior enumerated under proposed § 201.306, AMS should provide a non-exhaustive list of prohibited conduct known to harm producers, saying this measure would provide clear guardrails and foster quicker termination of abusive practices against producers. These commenters also said the deception provisions of the proposed rule fall well within AMS's authority under the Act, noting that Congress gave USDA broad powers under the Act with the intention of halting unfair trade practices against producers before producers suffer actual harm.</P>

                         AMS is making no changes to the rule as proposed. AMS appreciates the views expressed by commenters but believes specifying the duties of regulated entities to engage honestly and itemizing prohibited deceptive practices adds unnecessary complexity. Firstly, specific guidance as to what constitutes deceptive practices can be taken from existing regulations in 9 CFR part 201, such as: §§ 201.49 and 201.71 (requiring honesty in weighing); § 201.53 (requiring honesty in representation of market conditions or prices); § 201.98 (requiring honesty in collection of fees); § 201.67 (prohibiting deception regarding the nature of packer and selling agency business relationships); and § 201.217 (requiring transparency regarding breach of contract determinations). Secondly, in the event deception occurs in ways actionable under sec. 202(a) of the Act, yet that violation is not specifically covered by this rule, AMS will look to the legislative history and case law of the Act to guide its handling of these matters. For example, obvious falsehoods, such as false weighing and false accounting have always been considered deceptive practices under sec. 202(a) of the Act. Therefore, AMS believes it is not necessary to itemize such practices in this particular section. Lastly, AMS underscores that this rule is intended to provide a broad array of coverage regarding the general circumstances that encourage the provision of false or misleading information. Facts and circumstances are unique to every case and may vary significantly; therefore, AMS has determined to retain the four broad prohibitions on behavior under § 201.306 as initially proposed.

                         A poultry industry trade association said all actions prohibited under proposed § 201.306 are already addressed in sec. 202(a) of the Act, which prohibits regulated entities from engaging in unfair, unjustly discriminatory, or deceptive practices or devices.

                         AMS is making no changes to the rule as proposed based on this comment. AMS agrees that the prohibitions established by this rule are well within the scope of sec. 202(a) of the Act. This rule is designed to help producers better understand what behavior constitutes a violation of sec. 202(a). Based on complaints and comments from stakeholders over the years, as well as in response to the proposed rule, AMS is aware that deceptive practices continue to harm producers and market integrity. Thus, AMS has determined it necessary to codify in its regulations deceptive practices prohibited under sec. 202(a) of the Act to better ensure that producers benefit from the protections intended by the passage of the Act.

                         An agricultural advocacy organization suggested the final rule's explanatory text should clarify that deceptive practices related to contract formation also include the making of false or misleading statements to prospective producers on the benefits of a contractual relationship with a regulated entity. The commenter said that this clarification would, for example, better address circumstances such as representatives of live poultry dealers who make verbal claims to prospective growers about benefits not reflected in the actual contract the grower later receives to sign.

                         AMS is not making the specific changes to proposed § 201.306(b) requested in this comment but is making changes to this paragraph to clarify the range of deceptive conduct prohibited during contract formation. AMS agrees with the commenter regarding the harm of false statements in contract formation. AMS formulated § 201.306(b) specifically to address the making of false statements in contract formation. The revised regulation states that not only is a regulated entity prohibited from employing a “false or misleading statement” but it also may not omit “material information necessary to make a statement not false or misleading.” Therefore, AMS believes the regulation encompasses the protection against misleading statements requested by the commenter. AMS will address the specific circumstances raised by the commenter via other rulemakings.

                         An agricultural advocacy organization pointed out a potential discrepancy, saying the range of deceptive behavior in contract formation, performance, and termination covered in § 201.306(b) through (d) of the proposed rule as drafted appears narrower than that contemplated in the proposed rule's preamble. The commenter noted that the preamble said USDA generally approaches deceptive practices from the perspective of a reasonable party 
                        <PRTPAGE P="16157"/>
                        receiving them and asks whether they would affect the conduct or decision of a reasonable recipient of these practices and asserts that the Act reaches beyond common-law fraud to affirmatively require honest dealing and truthfulness in the marketplace.

                         The commenter said that, if AMS intended the description in the preamble to encompass a broader range of deceptive behavior than that in the proposed rule's current language, it should broaden the language in § 201.306(b) through (d) of the proposed rule to prohibit any practices likely to mislead a covered producer, acting reasonably under the circumstances, to the producer's detriment.

                         There is not a contradiction or discrepancy between the preamble and the proposed regulation. The preamble discusses deception more generally, providing background on AMS's approach to implementing the prohibition on deceptive practices and its legal authority to do so under sec. 202(a) of the Act. The regulatory text is designed to provide example prohibited deceptions under the Act. It is not designed to enumerate every circumstance that may be a prohibited deceptive practice under the Act. There are circumstances where a deceptive practice could be covered under sec. 202(a)'s prohibition on deceptive practices even if that practice is not expressly addressed by this final rule. AMS chose not to provide an exhaustive coverage of every possible circumstance that could be a deceptive practice because such an effort would be unwieldly as a matter of rulemaking and likely offer little benefit to producers in terms of making the protections of the Act concrete and understandable. Such an effort would require such breadth of coverage and flexibility in application as to effectively replicate the interpretive process that is needed to analyze deceptive practices under the Act, which may vary significantly depending on the facts and circumstances of each case. In this rule, AMS has instead chosen to strike a balance, and is offering clear protection for a broad range of commonly encountered circumstances. AMS notes that the regulatory text in paragraphs (b) through (d) does include a prohibition on employing a “false or misleading statement.” Therefore, AMS is making no changes to the regulation as proposed.

                         Agricultural advocacy organizations urged AMS to expand and clarify the proposed rule's prohibition on deceptive conduct during contract refusal, saying regulated entities can use this tactic to manipulate producers, as they may do with contract termination. The commenters gave the example of a dominant buyer who only wants to purchase cattle from producers locked into AMAs, rather than those selling on a negotiated cash market, so it can pay lower than fair market value. If this buyer simply tells producers on the open cash market that it does not need their cattle, this statement may not necessarily be false or misleading, but it would be a pretextual justification for refusing to deal with them. A cattle industry trade association also urged AMS to ban the practice of refusing to buy a producer's cattle in the negotiated cash market unless the producer agrees to enter a forward contract, saying this practice is so widespread that it is common knowledge among cattle producers that packers who say they do not need their cattle are tacitly providing them with an ultimatum.

                        <E T="03">AMS Response:</E>
                         AMS has designed the prohibition on deceptive practices in refusal to contract differently than the prohibition for other circumstances because the relationship between a regulated entity and a covered producer differs in this circumstance. During contract formation, performance, or termination, there is a high degree of reliance by the covered producer on the regulated entity, owing to the existence of the contract. In a refusal-to-contract circumstance, however, the reliance is limited principally to the denial of the opportunity to transact. In general, regulated entities may refuse to contract with a covered producer for any reason or no reason at all, unless the reason is impermissible under the Act. This final rule's prohibition on deception seeks to ensure that any reasons provided by the regulated entity to the producer are truthful and not misleading. Failure to provide such truthfulness is deceptive because, given the high levels of vertical integration and horizonal concentration, producers lack marketing options and thus heavily depend on regulated entities for market integrity and, ultimately, the information needed to compete effectively. Producers are harmed when they cannot evaluate their competitive opportunities in an honest, objective manner. While the USDA Extension Service and other third parties may assist producers in appreciating their competitive strengths and weaknesses, ultimately the signals sent by packers are critical for competitive opportunities.
                    </P>
                    <P>The final rule does not include “pretext” or “omission of material fact necessary to make a statement not false or misleading” in this refusal to contract provision because refusals to contract may occur for any number of reasons, and regulated entities may not always be in a position to reveal the reason for a refusal to contract. There may be economic, social, community, or even simply polite reasons for offering an incomplete, if not untruthful, reason for a refusal to contract. As long as a regulated entity is not providing false or misleading information to a covered producer or omitting material information, it will not run afoul of § 201.306(e).</P>
                    <P>AMS appreciates the commenter's concerns regarding the use of forward contracts. However, including a specific prohibition regarding this practice was not under consideration in the proposal. With this rulemaking, AMS is implementing regulations to provide a broad array of coverage against deceptive practices during various stages of the contracting process. Deceptive acts in contract refusal will be determined on a case-by-case basis based on the facts and circumstances of each individual case. In the example raised by the commenter, were a packer to refuse to purchase cattle in the cash market and state that its plant has acquired all the cattle it needs, the packer would not run afoul of the final rule if that statement was true. However, were the packer to make such a statement but would be willing—or attempt—to purchase the cattle under a different marketing arrangement, that would suggest that the information provided was false or misleading and the packer would run afoul of the final rule. If the cattle were of a quality or type that the packer does not want and the packer has already acquired all the cattle it needs for a given week, the packer could state that it is full without telling the covered producer its real reason for refusing to purchase cattle—again, as long as the statement provided is truthful.</P>
                    <P>Accordingly, AMS is not making any changes to the regulation as proposed in response to these comments.</P>

                         AMS is not adopting the recommendation. “Not limited to” language is unnecessary, as paragraphs (b) through (e) of this section are not stated as being exhaustive. This regulation is not designed to, and should not be read to, create an exclusive or exhaustive set of instances of deceptive practices. This rulemaking is intended to provide guidance to covered producers for how to effectuate their rights under the Act by implementing regulations that provide a broad array of coverage against deceptive practices during various stages of the contracting process. Future rulemaking or enforcement actions would not be restricted to the conduct identified in § 201.306 when dealing with deception, as the Act's coverage is broader than this final rule.

                         An agricultural advocacy organization recommended that AMS address common cattle contracting practices that enable regulated entities to consolidate their power, expand their profit margins, and shift their risks to producers, particularly those practices facilitated by increased use of AMAs. The commenter asserted AMAs, which are typically contracts for future delivery of cattle where the price paid at time of delivery is tied to a contemporaneous price such as that in the “spot” cash market for cattle, give packers ample opportunity to offload the risks of changes in the spot market onto producers by manipulating the prices they pay them at delivery. The commenter cited several ways in which the prevalence of AMAs shapes the market to packers' advantage. According to the commenter, animals under AMAs contribute, along with those directly owned by packers, to a large “captive supply” of cattle for packers, which gives these regulated entities substantial control over the cash price of beef. In addition, the commenter said lack of participation in spot markets means they provide less reliable price signals for AMAs, allowing packers to easily conduct limited spot market sales at low prices, in turn lowering the prices they pay producers at time of delivery.
                    </P>
                    <P>
                        The commenter argued that many of these packer practices relating to AMAs are deceptive because they can induce producers to enter into contracts in which they do not fully appreciate the extent to which packers control the applicable risks. At a minimum, the commenter urged AMS to clarify that the proposed rule's ban on deceptive practices extends to packer manipulation of spot market prices to lower the price paid to independent producers at time of delivery. The commenter also stressed that it would prefer AMS to introduce a comprehensive prohibition of deceptive practices associated with AMAs to avoid placing the burden of identifying manipulation on individual producers. Specifically, the commenter recommended that AMS require forward livestock contracts to include a firm and predictable base price, so packers have no room to manipulate prices, citing the recent Cargill case under which DOJ alleged that contracts executed by major poultry processor defendants under the tournament system violated the Act. The final judgment agreed to by the parties and entered by the Court requires that the defendant processors pay contract poultry growers a firm and predictable base price.

                         An agricultural advocacy organization recommended that AMS add a provision to § 201.306 establishing a standard for contract completeness and providing that use of contracts that do not meet these minimum standards constitutes an unlawful deceptive practice under the Act. The commenter argued this measure would help producers operating in monopolistic regional markets, saying integrators often take advantage of the lack of buyer-side competition by unilaterally dictating base prices, providing deceptive earnings claims, offering incomplete and one-sided contracts leaving out key terms such as the number of flocks a poultry grower can expect to receive, and coercing producers into taking on additional debt to upgrade their facilities. The commenter recommended that the proposed rule specify that complete contracts include the expectation that contracts clearly state a minimum price or rate of pay for products or services rendered; a detailed disclosure of potential expected capital investments necessary for a continued contractual relationship; and a minimum commitment of contract years, annual animal placements, and stocking density sufficient for the producer to maintain any contractually expected debt payments at the minimum guaranteed price or payment rate. The commenter also suggested AMS clarify that it would be unlawful retaliation for an integrator to coerce, intimidate, or break contract with a producer based on the producer's unwillingness to implement integrator-desired upgrades not previously detailed in a complete contract, as long as the producer's infrastructure is legally compliant and in good working order.

                         AMS understands that in highly concentrated buyer markets, producers may have limited control over contract terms due to the limited availability of buyers; however, AMS will not be establishing minimum standards for contract completeness via this rulemaking. This rule is intended to address broad areas of specific concern, not exhaustively identify all deceptive practices that could violate sec. 202(a) of the Act. Deceptive acts in contracting will be determined on a case-by-case basis based on the facts and circumstances of each individual case. Similarly, AMS will not be amending the regulations prohibiting retaliation (§ 201.304(b)) to implement the commenter's specific circumstance regarding unwillingness to implement upgrades not previously detailed in a complete contract. This comment is outside the scope of this rulemaking and AMS is making no changes to the rule based on this comment.

                         An agricultural advocacy organization said the categorical approach to governance in the rule as proposed is appropriate because itemizing the likely deceptive actions more effectively draws attention to the various deceptive actions potentially used by regulated entities. This commenter indicated that either approach to structuring would be effective but said the structure as proposed would better make current producers and prospective aware of the types of potential deception they may encounter. It also indicated support for the approach to employing of false or misleading statements, pretexts, or omissions AMS took in the proposed rule.

                         Whether the contract language was clear and written in a language the producer understands would be part of any evaluation to determine whether a statement (including any omission of material information) was false or misleading and that determination would be dependent on the particular facts and circumstances of the contract. This rule is intended to cover not only the poultry industry, but the swine and cattle industries. As such, it focuses on general circumstances that may give rise to the provision of false or misleading information. Therefore, AMS is making no changes to the rule based on this comment.

                         A poultry industry trade association and several live poultry dealers said the deceptive practices provisions of the proposed rule would discourage legitimate adverse actions by companies, making the system less efficient overall. First, the commenters said AMS does not provide guidance on how it defines “pretext” or how a regulated entity would demonstrate that an explanation is not pretextual, which raises uncertainties in terms of compliance and may dissuade companies from providing detailed explanations to producers to avoid the potential for second-guessing on motive. The commenters also said the proposed rule is unclear about whether regulated entities seeking to avoid a potential omission of material fact need to mention every business reason that contributed to a decision even if other factors were more relevant. In addition, the commenters said the proposed deception provision makes it more challenging to terminate relationships with contractors who perform poorly or mistreat animals, giving regulated entities incentive to keep these contracts in place rather than risk lawsuits over whether any communications leading up to the termination were deceptive and resulted in fewer opportunities for new entrants to the poultry industry.
                    </P>
                    <P>A swine industry trade association said the deceptive practices provisions would likely lead to costly litigation because the rule is overly broad and vague in its description of prohibited conduct. For example, according to the commenter, the proposed rule does not provide any definition or guidance on what constitutes a “material” fact, which is deceptive if omitted, and its ban on deceptive practices with respect to “any matter” related to livestock, meats, or live poultry does not clearly establish the scope of conduct at issue. In addition, the commenter said much of § 201.306 is unnecessary because other laws already sufficiently restrict the conduct at issue.</P>
                    <P>
                        <E T="03">AMS Response:</E>
                         Section 201.306 is designed to address deceptive practices in the marketplace by establishing four categories in the contracting process where deceptive practices commonly occur. The aim is to promote a marketplace that is free from the type of injury the Act was designed to prevent. Such a framework is necessarily broad, as the commenters noted, however, this framework is not intended to, and should not, cripple regulated entities' decision-making or the system overall.
                    </P>
                    <P>AMS must help ensure that regulated entities are truthful in their dealings with producers. Under these rules, AMS would seek to uncover the real motive for a regulated entity's treatment of a producer with whom they are forming or have a contractual relationship. AMS is including a prohibition against false or misleading statements, or omission of material information necessary to make a statement not false or misleading (in paragraphs (b) through (d)) to protect producers from conduct that employs deceit to disguise a regulated entity's genuine motive. Over the years, producers have reported concerns regarding their inability to understand and appreciate the real reasons why regulated entities take certain actions against them, in particular with respect to certain actions such as reduced chick placement or contract termination. For example, producers have asserted that sometimes a regulated entity will suddenly enforce certain parts of a contract in a stricter manner—such as animal welfare guidelines—even though the regulated entity had earlier found the producer's conduct under the contract acceptable. Producers assert that this is an example of a form of retaliation for actions by the producer or a deceptive practice to accommodate unrelated economic decision-making. Producers need to understand the real reasons for regulated entities' decision-making both to protect themselves from specific inappropriate adverse actions (such as undue prejudice or retaliation) and to be able to compete more effectively in a concentrated marketplace. If they cannot learn the real reasons why certain actions are taken against them, they cannot plan or mitigate the risks they may face. Therefore, AMS believes it is crucial to establish a regulatory framework prohibiting deceptive practices in contracting. AMS believes such a framework should provide broad, non-exhaustive prohibitions to provide better coverage for producers against deceptive practices in various stages of the contracting process. AMS may refine this framework via future rulemakings if the need arises.</P>
                    <P>With respect to the commenters' view that AMS does not provide guidance on how it defines “pretext” or how a regulated entity would demonstrate that an explanation is not pretextual, AMS adopted clarifying language by withdrawing its use of “pretext” and relying on the prohibition against employing a “false or misleading statement.”</P>
                    <P>With respect to the commenters' critiques regarding the materiality standard, under the FTC's Policy Statement on Deception, “material” refers to information that would affect a consumer's—in this case, producer's—conduct or decision-making, from the perspective of a producer acting reasonably under the circumstances. Act precedent may not require AMS to follow FTC's precedent in all circumstances, but AMS has designed the rule to satisfy the approach set forth in the FTC Policy Statement on Deception in this set of deceptive practice prohibitions. AMS is not seeking to establish a “but for” standard; however, the materiality of the information is already embedded in the regulated entity's act of “employing” the omission on which the covered producer has relied on in the contracting activity under § 201.306. Commenters also expressed concern about § 201.306's prohibition against the omission of material facts, questioning whether compliance would require that regulated entities mention every business reason that contributed to a decision even if other factors were more relevant. AMS notes that proposed § 201.306(b) through (d) specified that the prohibition applies to the “omission of material fact necessary to make a statement not false or misleading.” If one of the factors that contributed to a regulated entity's business decision was not material or relevant, then the omission of that information would be unlikely to make a statement false or misleading from the perspective of a producer acting reasonably under the circumstances. AMS therefore made no changes to the proposed regulations in response to this comment; however, AMS notes that as discussed in Section V—Changes from the Proposed Rule, AMS made several changes to the verbiage of § 201.306(b) through (d), including replacing the phrase “omission of material fact” with “omission of material information.”</P>
                    <P>
                        In response to commenters' concerns regarding the potential for increased litigation, AMS acknowledges that the provisions of § 201.306 could result in additional litigation because the regulations could provide producers new hope for relief from deceptive conduct in the contracting process. However, as discussed in more detail in this rule's Regulatory Impact Analysis in Section VIII.B., AMS does not expect large increases or decreases in litigation from this rule. Though commenters expressed concern that this regulation will lead to costly litigation because it is too broad and vague, AMS notes that in this final rule the Agency has provided additional clarity on the meaning of “material” in these 
                        <PRTPAGE P="16161"/>
                        regulations and removed use of the word pretext. AMS also rejects the commenter's assertion that the rule is overly broad and vague in its ban on deceptive practices with respect to “any matter” related to livestock, meats, or live poultry because this assertion is inaccurate. This regulation does not ban any deceptive practice related livestock, meats, or live poultry: paragraph (a) establishes that the scope of § 201.306 is prohibiting deceptive practices that occur in specific stages of the contracting process. These stages are then delineated in paragraphs (b) through (e). AMS notes, however, that it has removed the words “any matter” from § 201.306(a).
                    </P>
                    <P>With respect to the commenter's view that § 201.306 is unnecessary, AMS disagrees. AMS believes that, while USDA regulations prohibiting specific deceptive practices already exist, a regulatory framework prohibiting deception during the contracting process is necessary because this will provide much-needed certainty and predictability to the interpretation of this section of the Act.</P>

                         An agricultural advocacy organization recommended that AMS introduce a recordkeeping requirement related to deceptive practices to help it enforce these practices.

                         In response to commenters' suggestions, AMS notes that regulated entities are already required to maintain records pertaining to their business activities (see 9 CFR 201.95). In light of existing law, a specific recordkeeping requirement covering every statement or interaction that could amount to deception is not appropriate as it could be expensive and burdensome, while yielding little benefit in terms of usable, searchable information. AMS will monitor regulated entities' practices to evaluate whether additional requirements are necessary. AMS further notes that should specific problems emerge, heightened recordkeeping could be a requirement arising out of enforcement actions or adopted in future rulemaking.

                    <P>AMS is not adopting the commenter's suggestion regarding examples of contract terms and procedures related to tournament settlements and input quality because they are outside the scope of this rule. AMS made no further changes in response to the comments.</P>

                         Agricultural advocacy organizations said AMS should require all contracts to be in writing because doing so is necessary for enforcing the Act. These commenters said AMS should also require regulated entities to make all claims to prospective producers in writing to deter false or misleading statements designed to encourage signing of a contract.
                    </P>
                    <P>A plant worker indicated support for requiring all contracts to be in writing, while noting that some benefits would be limited. According to the commenter, introducing this type of requirement would help producers by providing a record of the transaction and an increase in transparency. However, the commenter also said such a requirement would be less likely to address packer pressure on producers to use formula market arrangements to incentivize cattle quality if the packers present these arrangements as take-it-or-leave-it offers, although it would at least help create an environment that is transparent about material terms. The commenter also said that many jurisdictions may already require contracts to be in writing to satisfy the statute of frauds, especially if they cover multiple years, thus making a provision requiring written contracts potentially redundant in some cases.</P>
                    <P>
                        <E T="03">AMS Response:</E>
                         AMS appreciates the commenters' views on the value of written contracts and agrees that written contracts have significant benefits for reducing deceptive practices and encouraging market integrity. Written contracts provide both parties clearer understanding of their positions and the opportunity for regulators to review and evaluate the functioning of the market. However, AMS also recognizes that it is a longstanding trade practice in the agricultural sector for many parties to negotiate and assent to contract terms orally, which holds the same weight under the law as a written contract. USDA has pursued many cases based on the violation of unwritten terms, and this will not change. Requiring that all contracts be in writing would more significantly affect cattle markets, as more of those markets remain cash-negotiated. Contract formation regarding the purchase and sale of livestock often occurs over the phone and quickly. Requiring written contracts would impede the ability of parties to conduct business expeditiously, which is often necessary in fluctuating commodity markets, especially for perishable products like meat. Vertically integrated contract growing arrangements, which are nearly universal in poultry and widespread in hogs, are more characterized by written contracts already. In this rule, AMS is choosing not to adopt a requirement for written contracts or claims in all circumstances. While AMS believes that written contracts are a good practice, especially in light of changes in technology (like email and electronic signatures), AMS believes additional study and consideration is needed and is deferring for future consideration whether a mandate is appropriate.

                         An agricultural advocacy organization said it agreed with AMS that a decision or action on the part of a regulated entity to stop buying on the cash market is more analogous to a contract termination than a refusal to deal but notes that these decisions or actions also share key features with the latter. The commenter provided the example of a packer who refuses to buy cattle in the cash market from a covered producer who regularly sells on the cash market unless the producer agrees to enter a forward contract with a packer; this act would constitute both refusal to deal and termination of a contract, and would also be a form of prohibited retaliation.

                         AMS agrees that a circumstance where a packer refuses to buy cattle in the cash market from a covered producer who regularly sells on the cash market to the regulated entity is analogous to a contract termination, as past court decisions have recognized a remedial duty under the Act to a make purchases in certain circumstances.

                        AMS did not make any revisions to § 201.306 in response to this comment; however, AMS is clarifying in § 201.304(b)(3)(iv) of this final rule that refusing to deal with a covered producer refers to refusing to deal on terms generally or ordinarily offered to similarly situated covered producers, which would include the producer's prior status quo. This would address the case where a producer has a prior track record of regular sales to the packer but is cut off. AMS also added § 201.304(b)(3)(vi) to further clarify that harm to a producer on the basis of protected activities is intended broadly to capture materially adverse retaliatory action that a packer may take against a producer.

                         AMS agrees that a severability clause is appropriate because the undue prejudice, retaliation, and deception sections of this rule can be enforced as stand-alone provisions. They are not interdependent, therefore the exclusion of one does not disqualify any of the others. For this reason, as discussed in more detail in Section VI.F—Provisions of the Final Rule, Severability, AMS has included under § 201.390 a severability clause in its final rule.

                         AMS agrees with commenters that the final rule should provide a clear effective date for implementation. The AMS Act final rule “Undue and Unreasonable Preferences and Advantages Under the Packers and Stockyards Act” was published on December 11, 2020, and became effective on January 11, 2021, providing a 30-day period. AMS believes that this rule presents a similar scope of rulemaking coverage, relating to basic principles that regulated entities themselves have acknowledged they already comply with. However, in response to requests from commenters for additional time, AMS will give 60 days, which the Agency feels provides adequate time for regulated entities to become compliant with this rule given the low cost and minimal process changes required to do so. Accordingly, within 60 days of publication in the

                         Several live poultry dealers and trade associations took issue with the accuracy of cost estimates in the proposed rulemaking. A poultry industry trade association and several live poultry dealers contended that the Agency's first-year estimate of $504 per live poultry dealer to comply with the proposed rule is a drastic underestimate. They argued that the costs of physical filing cabinets to maintain the requisite paperwork alone would exceed the estimated first-year cost, and that recordkeeping and computer systems to digitally maintain records would be more costly. The commenters also contended that the AMS cost estimates overlooked significant labor costs that would be required to comply with the new rules, including legal services.

                         AMS disagrees with commenters' assertions regarding the accuracy of its cost estimates. AMS subject matter experts calculated the estimated compliance and recordkeeping costs associated with this rule. These experts are economists and supervisors in AMS's PSD with many years of experience conducting investigations and compliance reviews. AMS stands behind their estimates. AMS believes that the costs associated with this rule will be minimal: the first-year total cost is estimated to be $586,000, or 0.0002 percent of revenues, given that total sales of beef, pork, and broiler chicken was approximately $294.5 billion in 2022.

AMS estimates that the total cost for each succeeding year would be $298,000, or 0.0001 percent of revenues.

                        With respect to commenters' assertion that AMS has neglected to account for labor costs, including legal services, AMS notes that in the proposed rule's Paperwork Reduction Act analysis, AMS provided a compliance cost breakdown for the hours required of attorneys, as well as administrative assistants, managers, and information technology staff. AMS does not expect large increases or decreases in litigation costs, and thus regulated entity legal services. The clarity provided by the rule encourages regulated entities to proactively avoid prejudicial, discriminatory, and deceptive practices that could otherwise lead to costly litigation. Likewise, the rule could also provide producers hope for relief from the courts for perceived prejudicial, discriminatory, and deceptive practices, which could, in turn, increase litigation but would return benefits to producers in reduced harms. In response to commenters' concerns regarding the costliness of the rule's recordkeeping requirements, AMS argues that the recordkeeping requirements were crafted to provide flexibility for regulated entities. The rule does not prescribe the manner in which records must be stored. If a regulated entity finds the cost of filing cabinets prohibitive, the entity may choose whichever means of file retention is most cost effective, including currently available computer filing systems, which most companies maintain in the normal course of business. Additionally, the rule provides regulated entities leeway to determine which records they choose to maintain. Because this rule applies to regulated entities across a

                        variety of industries and of varying sizes, AMS did not prescribe a set of records each entity must retain, regardless of their relevance to a particular entity's circumstances. Some firms might not have any records to store. Others may already store relevant records and may have no new costs. Therefore, the rule saves regulated entities from the burden of maintaining records irrelevant to their circumstances.

                         Many industry companies and trade associations argued that the cost estimates put forward in the proposed rule ignore significant litigation costs that would be inevitable under the proposed regulations. A cattle industry trade association disagreed with AMS's cost analysis that the rule could plausibly reduce litigation costs “if companies come into compliance without any enforcement action.” The trade association argued that the rule contains vague standards and eliminates the requirement that a plaintiff must show competitive harm, both of which would lead to a proliferation of litigation. It asserted that the threat of litigation would cause packers to reduce their legal risk exposure by standardizing their contracts with producers, which could be costly for producers who benefit from contracts tailored to their individual needs or conditions (

                         cattle weight targets based on geographic location and regional feedstuffs availability). Finally, it noted that AMS itself acknowledged that GIPSA declined finalizing the agency's proposed rule in 2016—the Farmer Fair Practices Rule—because it contained ambiguous terms that would increase litigation between regulated entities and producers.

                         The dealer also said that if the proposed rule is implemented, the company would no longer have incentive to contract with individuals due to litigation risk and would need to rely more heavily on company-owned farms to raise its poultry. It argued that the result would be decreased grower competition and thus decreased grower pay, resulting in another unmeasured cost of the proposed rule.

It said that frivolous litigation that misunderstands or capitalizes on vagueness in the rule would add significant litigation costs. The trade association estimated the cost of compliance with the new rule (including anticipated litigation) to be more than $100 million to the industry.

                         Litigation is possible following the passage of any rule. The threat of such litigation does not preclude AMS from fulfilling its mandate to administer the Act. AMS believes that discriminatory, retaliatory, and deceptive practices only serve to exclude qualified producers from the market. Even if such conduct impacts a single producer, it can reasonably be inferred that, if unchecked, such conduct will proliferate and negatively impact other producers and the market. Therefore, it is the opinion of the Agency that such conduct must be stopped in its incipiency, or it will likely cause widespread harm.

                    <P>In response to commenters' complaint that AMS has overlooked significant litigation costs that would be inevitable under the proposed regulations, AMS does not expect large increases or decreases in litigation costs.

This effect would lead to a decrease in litigation costs. Likewise, the rule could also provide producers hope for relief from the courts for perceived prejudicial, discriminatory, and deceptive practices, which could, in turn, increase litigation costs but would return benefits to producers in reduced harms. AMS is uncertain as to which effect will dominate and to what extent and, therefore, does not estimate litigation costs in this analysis.</P>
                    <P>With respect to the comments regarding compliance costs for the 2016 Farmer Fair Practice Rule, commentors discussed that a trade association estimated the cost of compliance with rule (including anticipated litigation) to be more than $100 million to the industry. A commentor also noted that an independent economic analyses of previous AMS rulemakings on similar topics that estimated economic impact costs exceeding $1 billion. The 2016 Farmer Fair Practice Rule was a very different proposed rule with a much wider scope than this final rule, and AMS does not consider a comparison of the 2016 Farmer Fair Practice Rule and this final rule to be an accurate comparison. The costs of this final rule are much smaller than the estimated costs of the 2016 Farmer Fair Practice Rule. GIPSA estimates the average litigation cost of the 2016 Farmer Fair Practice Rule to be less than $9 million in the first year. Given the scope of this final rule is smaller than the 2016 Farmer Fair Practice Rule, AMS expects litigation to be smaller. This, combined with the offsetting effects of the increases and decreases in litigation, leads AMS to not consider adding litigation costs to the rule.</P>
                    <P>The assertion that packers will be forced to standardize all contracts to ensure conformity with the rule is without basis. Standardizing contracts may be one way to ensure fair treatment of producers, however, this rule in no way mandates such a response from packers. Similarly, AMS disagrees with the assertion that fear of litigation would remove any incentive to contract with individual poultry growers. The aim of the rule is to discourage abuses of power in the marketplace to allow qualified producers to participate freely in the market and receive full value for their efforts. Reliance on individuals to raise poultry evolved as an economically advantageous way for integrators to bring poultry to the market. AMS does not believe that a greater focus on ensuring honest dealing and honest decision-making is incompatible with this model. Further, AMS disagrees with the assumption that a regulated entity would need to abstain from contracting with individuals to ensure that they are not abusing their market power by operating in prejudicial, retaliatory, or deceptive ways.</P>

                        With respect to the comments regarding rules previously published by GIPSA, AMS notes that GIPSA's withdrawal of its 2016 rules was justified in part due to the rules' lack of clarity regarding prohibited behavior and the agency's perception that such ambiguity would increase litigation costs. This rule differs from the GIPSA rules by more clearly and specifically laying out the types of conduct that will 
                        <PRTPAGE P="16164"/>
                        be prohibited. Additionally, much has changed since the withdrawal of GIPSA's 2016 rules. In 2017, GIPSA merged with AMS. AMS now administers regulations under the Act and undertook this rulemaking to meet its statutory mandate. Also, in the years since the GIPSA rules were withdrawn, USDA has continued to receive complaints from producers regarding undue prejudice and unfair, unjustly discriminatory, and deceptive practices. When Congress, in April 2022, held hearings to discuss such concerns regarding the cattle and poultry markets, the hearings were marked by the absence of producers who chose to avoid public testimony for fear of retribution.

                        <FTREF/>
                         Meanwhile, the market remains highly concentrated and vertically integrated, which enables market power abuses and unjust distortions of the competitive landscape and makes any harms from them more significant. Smaller producers are unable to freely compete and receive fair value for their goods because in highly concentrated markets they often have no option but to do business with regulated entities which, in AMS's experience, have caused producers to experience unjust and adverse treatment. AMS has not been able to effectively address these complaints, partly because of the lack of clarity regarding its regulations under the Act and the ability for individuals to bring cases based on specific instances of harm. Therefore, it is now the Agency's belief that the potential costs of increased litigation are outweighed by the benefits to the market as a whole.

The commenter reasoned that because over 95 percent of packers reporting to AMS are small businesses, exempting such a large part of the industry would not be conducive to creating a uniform standard of recordkeeping and reducing deceptive practices across the industry.

                         An agricultural advocacy organization contended that AMS should clarify the role of litigation costs in its cost-benefit analysis. It argued that litigation resulting from proposed rulemaking should not be treated purely as a cost, since (1) changes in behavior by regulated entities to reduce violations of the Act and (2) compensatory awards to market participants that suffer from violations of the Act both result in benefits that AMS should weigh in calculating the net costs of the proposed regulation. The association said that the Act relies in part on private litigation to keep livestock markets competitive, and while AMS is right to be cognizant of litigation costs by providing clear and unambiguous language to forestall unnecessary legal proceedings, litigation in general should not be treated solely as an ancillary cost without considering the benefits it confers.

                         AMS is making no changes to the rule in response to this comment. Rulemaking procedure regarding the calculation of costs and benefits requires the inclusion of specific costs. The benefits of litigation are harder to quantify, and thus were not specifically included in the proposed rule. However, AMS agrees with commenter that there are benefits of litigation in that producers will be better able to protect themselves from undue prejudice, retaliation, and deception, and thus that litigation does not result solely in negative costs. By adding private rights of action to the Act as recently as 1987, Congress has expressly recognized that private litigation, or the threat thereof, is a force that shapes conduct for the protection of producers. To the extent that the threat of private litigation pressures regulated entities into compliance and keeps their conduct fair, litigation risks can serve to ensure this rule's full potential is realized.

                         Several live poultry dealers, an industry company, industry associations, a legal foundation, and an individual argued the proposed rule exceeds AMS's authority because it unlawfully seeks to transform the Act from an antitrust statute into a civil rights law despite Congress's clear intention to address the type of harm to producers covered by the proposed rule via other statutory schemes rather than under the auspices of the Act. They argued that, if these laws still do not cover certain types of mistreatment producers may face, the correct course of action is for Congress to revise these statutes or pass new ones, not for AMS to attempt to address them via the Act. For example, a cattle industry trade association noted that 42 U.S.C. 1981 already prohibits racial discrimination in private contracting in cases where the contractor cannot show harm to competition. The cattle industry trade association contended that, because Congress has never sought to expand the protections of section 1981 to other protected categories, AMS lacks authority to use the Act to effectively do 
                        <PRTPAGE P="16165"/>
                        so in the absence of enabling legislation. This commenter also noted that multiple other USDA statutes explicitly refer to socially disadvantaged groups and socially disadvantaged farmers or ranchers, saying the lack of such references in the Act itself indicates that Congress did not intend for issues relating to exclusion or disadvantage of covered producers to fall within its scope. A swine industry trade association said proposed § 201.304(a) of the proposed rule covers conduct already prohibited by the Act itself as well as by other antitrust and anti-discrimination laws, such as the Civil Rights Act of 1964, the Agricultural Fair Practices act, and the Robinson-Patman Act. Industry trade associations and companies said other statutes such as the Agricultural Fair Practices Act, the Capper-Volstead Act, and laws protecting farmers from retaliation if they act as witnesses in a Federal investigation already prohibit retaliation against essentially all covered activities under proposed § 201.304(b).

                         Consistent with the Act, this rule protects inclusive competition and market integrity, and is designed to ensure that fair and competitive conditions prevail in livestock and poultry markets. While this rule may in some ways resemble certain civil rights laws, it is distinct as it draws its authority from the Act, which sets forth a general prohibition on unjust discrimination and undue prejudice that is broader than civil rights statutes that focus solely on discrimination on account of a protected status. AMS believes that discrimination on the basis of an individual's characteristics—in particular, the bases (as set forth in § 201.304(a)) of race, color, religion, national origin, sex (including sexual orientation and gender identity), disability, or marital status, or age, and the producer's status as a cooperative)—has no place in the market for livestock and poultry. Prejudices, disadvantages, inhibitions on market access, or otherwise adverse actions against covered producers on these bases must fundamentally be viewed as unjust forms of discrimination, lest the word 
                        <E T="03">unjust</E>
                         be unmoored from its plain meaning. Moreover, this rule addresses the unique and often difficult-to-prove discriminatory conduct that has long existed in the agricultural sector. Demographic information is seldom recorded in agricultural transactions; therefore, it is difficult to quantify discrimination. However, as the preamble set forth, agricultural markets are not representative of the population as a whole, for reasons in part arising from a well-established track record of unjust discrimination from USDA itself. Unjust discrimination on the bases set forth in this rule does not stem solely from USDA's actions, rather it was widespread across society. Discrimination and prejudice have not been eliminated from society, and heightened steps are appropriate to prevent unjust discrimination from coloring public or private decision-making. Such clarity is especially important in today's highly concentrated agricultural markets, with few minority participants, as the lack of competition means that failure of inclusion for all farmers gives rise to a competitive harm under the Act.

                    <P>AMS recognizes that section 1981 of the Civil Rights Act establishes that certain rights are to be guaranteed, and these rights are to be protected against impairment by nongovernment and state discrimination. This rule addresses prohibited conduct specifically in the agricultural sector and is not superseded by section 1981. By expressly stating prohibited conduct that is violative of the Act, this rule seeks to allow AMS to better enforce the Act. AMS acknowledges that multiple USDA-administered statutes explicitly refer to socially disadvantaged groups and socially disadvantaged farmers or ranchers but underscores that AMS has replaced the definition of “market vulnerable individual” (which was more closely aligned with the formulations under those laws) with a simpler set of prohibited bases. And for the reasons described above, AMS's interpretation of the Act is faithful to its text and purposes. AMS notes that comments indicated that the Act in fact does prohibit the conduct set forth in this rule, in which case the rule will function to clarify and explicate already prohibited conduct.</P>

                        AMS notes commenters' argument that § 201.304(a) covers similar conduct as the Civil Rights Act of 1964, the Agricultural Fair Practices Act (AFPA), and the Robinson-Patman Act. However, the fact that such conduct is prohibited under those statutes does not mean that it is not also prohibited by the P&amp;S Act, which is broader in scope than other antitrust laws.

                         AMS believes it is appropriate to provide clarity regarding application of the Act because AMS has the authority to enforce the Act (and the AFPA), and not the Civil Rights Act of 1964 or the Robinson-Patman Act, with respect to livestock and poultry. The Act provides supplemental and parallel coverage to the AFPA, making its application appropriate and valuable to livestock producers and poultry growers who have, over the years, found it challenging to earn the full value of their animals in their dealings with packers and live poultry dealers.

                         A legal foundation and a cattle industry trade association claimed AMS's decision to broadly restrict discrimination against “market vulnerable” individuals exceeds its statutory authority. One commenter said this decision, and its likely result of leaving courts to flesh out the vague definition to determine whom the proposed rule should protect, is inconsistent with Congress's longstanding and repeated choices to ban discrimination using an approach based on protected classifications. Another commenter said AMS acts beyond its authority in proposing a broad definition of “market vulnerable” individuals because its goal in taking such an approach is to ensure that the rule can address prejudice based on categories such as sexual orientation or gender identity. According to the commenter, AMS cannot redefine the meaning of the key terms “undue prejudice” and “unjust discrimination” under the Act to include protections based on these categories because the Congress that enacted the Act in 1921 would not have contemplated such protections. The commenter further critiqued AMS's citation of

                         AMS accepts the comment that it would be burdensome for the courts to flesh out the vague definition of “market vulnerable individual” to determine who the proposed rule should protect and that the approach is inconsistent with Congress's longstanding and repeated choices to ban unjust discrimination using an approach based on protected classifications. Accordingly, AMS is adopting specific prohibited bases in this final rule.

The Act specifically addressed “unjust discrimination” and “undue prejudice” and left it to the Secretary to set out the scope of equitable terms such as “unjust” and “undue,” as well as “unfair.”

                         Industry trade associations said proposed § 201.304(a) inappropriately fails to incorporate the requirement from section 202(b) of the Act that a prejudice or disadvantage be “undue or unreasonable” to constitute a violation. The commenters said this provision would go against precedent which has concluded that the Act, as well as the broader antitrust regime, allows actions such as refusal to deal or non-renewal of a contract when conducted reasonably. One commenter said AMS exceeds its authority in omitting this statutory requirement from the proposed rule.

                         Therefore, this rule is within the Secretary's authority under secs. 202(a) and (b) of the Act. Under Act precedent, whether discriminatory conduct amounts to being “undue” or “unreasonable” is a determination that the statute provides broad discretion to the Secretary to determine. Advantages are not a component of this rule instead the rule focuses on prohibiting conduct that disadvantages producers based on characteristics unrelated to the quality of their products or services.

                         Multiple industry companies and associations, another organization, and an individual contended that AMS unlawfully rejected precedent by asserting that discriminatory conduct can violate secs. 202(a) or (b) of the Act without demonstrating injury, or likelihood of injury, to competition. The commenters cited legislative history and judicial precedent to argue that the Act is fundamentally an antitrust statute and is thus bound by the key antitrust principle of preventing harm to competition. Commenters said Congress's main concern in enacting the Act was preventing harm to competition from meatpacker monopolies and that, in drafting the Act, Congress used the basic blueprint of the Sherman Act and other existing antitrust statutes, which distinguish between fair competition and undesirable predatory competition. Commenters said interpreting secs. 202(a) and (b) to require plaintiffs to prove actual or likely harm to competition thus promotes the Act's main purpose of protecting healthy competition in the meatpacking industry. Commenters also cited numerous court cases holding that the Act requires a showing of injury to competition, including rulings spanning eight circuits.

A commenter argued that, in the absence of the harm-to-competition standard, courts will use a range of inconsistent means to establish violations of the Act, meaning individual cases will more likely require judicial resolution despite AMS's claim that its proposed approach will reduce litigation.

                         Congress designed the Act to provide broader protections than existing antitrust laws such as the Clayton and Sherman Acts due to specific challenges in agricultural markets.

                         The existence of the Act is proof that existing antitrust laws were not sufficient in protecting livestock producers and ensuring fair agricultural markets. It is well established that, to meet the needs of livestock producers more effectively, the Act provides broader protections than existing antitrust laws. The statutory text, case law, and legislative history make plain that the Act's protections extend beyond

                        antitrust laws.

                         Accordingly, it has been the Agency's longstanding position that because the Act addresses more and different types of harmful conduct than antitrust laws, a showing of competitive injury is not required to establish violations of secs. 202(a) and 202(b). Market abuses such as deception, unjust discrimination, and retaliation are illegal per se under the act. Addressing the harmful conduct this rule aims to prevent is squarely within the authority of the Secretary and accords with Congressional intent.

                         Moreover, the Secretary, exercising broad authority to define the scope of secs. 202(a) and (b), has determined that the prohibited practices are likely to exclude producers from the market, thereby lessening competition and causing widespread marketplace harm if not addressed in their incipiency, before competitive injury has occurred.

                             Title 9, part 201 of the Code of Federal Regulations (CFR). Section 407 of the P&amp;S Act (7 U.S.C. 228) provides that the Secretary “may make such rules, regulations, and orders as may be necessary to carry out the provisions of this Act.

                    <P>Commenters cite several circuit court decisions that required a showing of harm to competition or a likely harm to competition establish a violation of sec. 202. These cases involved private claims and do not control the Agency's statutory authority to promulgate regulations. AMS is within its statutory authority to promulgate rules that “assure fair competition and fair-trade practices, to safeguard farmers and ranchers . . . to protect consumers . . . and to protect members of the livestock, meat, and poultry industries from unfair, deceptive, unjustly discriminatory and monopolistic practices. . . .” Congress granted the Secretary broad authority to determine the scope of coverage of terms such as “unjust discrimination” and “undue prejudice” or “unreasonable disadvantage” under secs. 202(a) and (b) of the Act.</P>
                    <P>This rule aims to prevent market exclusion of producers who have been subjected to unjust discrimination on a prohibited basis or based on engaging in a protected activity, and to snuff out those harms at their incipiency. Based on its knowledge of the industry, AMS has determined that undue and unreasonable prejudice and unjust discrimination on the prohibited bases and the protected activities identified in the rule amount to conduct that negatively effects these markets, and therefore AMS is establishing these regulations to address that conduct at its incipiency, when it occurs against a single individual.</P>
                    <P>Additionally, deceptive conduct violative of the Act has routinely been enforced on an individual basis absent a required showing of any particularized harm to competition since the very first administrative actions brought by the Department. Deceptive conduct often takes the form of unfair contract formation, enforcement, and termination and therefore most frequently occurs on an individual basis. To require a showing of harm to competition to prove deception violations under the Act would be contrary to longstanding enforcement standards and is adverse to the intent of the Act to protect farmers and ranchers from deception. Furthermore, the assertion from commenters that this rule will result in costly “baseless” litigation is contrary to the findings of AMS. AMS has determined that this rule will not increase litigation significantly due to the assertion by regulated entities, through their comments, that they do not engage in the conduct this rule aims to prohibit.</P>

                         Several advocacy organizations and a cattle industry trade association supported AMS's position that prohibited conduct under the Act need not lead to market-wide harm to competition, with some urging AMS to explicitly state that a showing of such harm is not required under the proposed rule. An agricultural and environmental organization cited E.O. 14036 on Promoting Competition in the American Economy,
                        <SU>220</SU>
                        <FTREF/>
                         which called for a rule explicitly stating individuals should be able to prevail under the Act without proving market-wide harm. This commenter argued AMS needs to explicitly state its position to stop judicial confusion in the face of a Federal circuit court split on the competitive-harm issue. The commenter said that, since the proposed rule contains multiple references to both USDA's position on market-wide harm to competition and E.O. 14036's explicit direction to incorporate this position into a final rule, amending the rule to clearly adopt this position would be a logical outgrowth of the proposed rule.

                        An agricultural advocacy organization contended the text, structure, and legislative history of the Act indicate that it prohibits discrimination based on market-vulnerable and protected-class status, giving AMS the legal authority to promulgate regulations based on this interpretation. The commenter argued the Act's prohibition of differential treatment on an “unjust,” “undue,” or “unreasonable” basis encompasses all forms of discrimination based on a producer's market vulnerability or protected classification because it includes all actions that adversely differentiate between producers without a legitimate basis. The commenter said that, in using such words in the Act, Congress clearly intended to invoke national values and policies related to fairness and equal treatment, including equal protection jurisprudence as it existed during enactment. According to the commenter, this jurisprudence was understood to prohibit essentially unjust or arbitrary discrimination between persons or corporations “in a similar situation or condition.”

                    <P>The commenter next looked at secs. 202(a) and (b) of the Act in the context of the statutory scheme, contrasting their broad reach with the more limited scope of secs. 202(c) through (f), which specifically target business practices with anticompetitive effects, and arguing this difference implies Congress intended for these first two sections to apply more expansively. This commenter further claimed, if unfair, discriminatory, prejudicial, or deceptive conduct always required proof of market-wide competitive injury, these paragraphs would be superfluous because paragraph (e), which prohibits “any course of business” or “any act” for the purpose or with the effect of causing competitive injury, would always apply. The commenter said this broad interpretation of secs. 202(a) and (b) to include discrimination based on protected-class or market-vulnerable status easily advances the Act's statutory purpose of ensuring fair competition and trade practices in livestock markets, noting that this type of discrimination reduces output and prevents efficient resource allocation by restricting certain producers' ability to enter and participate in markets. The commenter also said legislators enacting the Act sought to broadly address imbalances between buyers and sellers of livestock, referring in detail to the Act's legislative history for evidence that Congress intended for it to have an expansive scope, including coverage of a wide range of unfair and unjust practices.</P>
                    <P>
                        The commenter also argued that the prohibitions in secs. 202(a) and (b) do not merely include intentionally 
                        <PRTPAGE P="16168"/>
                        discriminatory actions but also extend to actions with a disparate impact on covered producers based on their protected-class or market-vulnerable status. To support this position, the commenter noted that sec. 202(a) prohibits regulated entities from engaging in practices or using devices that are “unjustly discriminatory,” rather than simply prohibiting them from actively discriminating, and that sec. 202(b) prohibits regulated entities from “subject[ing]” persons or localities to undue or unreasonable prejudices or disadvantages, arguing that both provisions specifically use language intended to encompass non-intentional actions.

                        The commenter further argued that AMS holds authority to interpret the meaning of sec. 202 and identify practices that violate its prohibitions. The commenter said Congress modeled USDA's role under the Act on that of the Federal Trade Commission under the FTC Act, envisioning an authority with broad jurisdiction and power. According to the commenter, Congress even went beyond the FTC Act model in one respect in its grant of authority to USDA, with sec. 407 of the Act giving USDA unequivocal authority to promulgate rules as needed to carry out its provisions. The commenter also said many court decisions have given strong deference to USDA determinations on whether a practice violates the Act, relying on reasoning that the facts of individual cases determine the meaning of the Act's operative terms, and that USDA is responsible for efficiently regulating market agencies and packers. Finally, the commenter argued “

                         USDA maintains that this consistently held position is based on the language, structure, purpose, and legislative history of the Act, and USDA continues to adhere to this longstanding position, notwithstanding the disagreement of some courts as to the relationship between harm to competition and violations under the Act. Discrimination and undue prejudice on the bases set forth in this final rule are both essentially unjust and undue as forms of unacceptable personal discrimination under the Act (drawing on similar precedent from the ICA and from P&amp;S Act implementation in stockyards), and also subvert normal market forces, undermine market integrity, and deprive producers of the true value of their products and services. AMS has not incorporated the suggested § 201.308 provisions because the rule itself prohibits discrimination against an individual producer on the prohibited bases or protected activities. The proposed rule elaborated on the regulatory text, stating “[t]his proposed regulation sets forth specific prohibitions on prejudicial or discriminatory acts or practices against individuals that are sufficient to demonstrate violation of the Act without the need to further establish broad-based, market-wide prejudicial or discriminatory outcomes or harms.” 
                        <SU>224</SU>
                        <FTREF/>
                         AMS's position is that under the Act even a single instance of discriminatory or prejudicial conduct may violate the Act.
                        <SU>225</SU>
                        <FTREF/>
                         The Act prohibits “essentially unjust” discrimination and undue prejudice, which AMS has determined the provisions of this final rule to address. Moreover, discrimination on prohibited bases and retaliation on the basis of protected activities in livestock and poultry markets leads to economic inefficiency, and has no procompetitive justification. Undue prejudices or disadvantages and discriminatory practices in a concentrated livestock or poultry market inflict economic harm through a distortion of market signals such as a distortion of market prices and exclusion of market participants, which, in turn, can lead to disinvestments in the livestock and poultry markets and a misallocation of scarce resources. Deception deprives the seller of the benefits of the market, as competitors of the initial deceiving regulated entity may be induced to likewise engage in such practices. When market abuses become widespread, market success becomes less based on productive efficiency or quality and more on who can engage in the most abuses, leading to allocative inefficiencies and loss of social welfare.

                         Commenters representing industry perspectives said proposed § 201.306 on deceptive practices is outside the scope of the Act because it would require all tort or contract disputes under the Act to be addressed in Federal courts rather than as State matters. According to the commenters, Congress would have explicitly said so if it intended to give AMS wide-ranging authority to regulate the specifics of livestock industry contracts and business practices regardless of their effect on competition. According to commenters, further evidence that Congress did not intend to give the agency such authority includes its previous rejections of other proposals to expand the Act to cover contractual matters traditionally covered under State law, with Federal courts likewise holding that the Act does not cover these circumstances.

                        require proof of a particularized intent contradicts the plain text of the statute as it would have been interpreted at enactment. According to the commenter, Congress at this time would have understood meatpacker conduct only to be deceptive when committed with the intent to deceive a producer. The commenter further stated that AMS's arguments that deceptive practices under sec. 202 of the Act do not necessarily require intent to deceive—based on analogy to developments in the law of deceptive marketing—do not provide sufficient support for its position. An organization asserted that the proposed rule attempts to undercut Federal court rulings, such as

                         This rule does not require all tort or contract disputes under the Act to be addressed in Federal courts rather than as State matters. It only addresses the specific prohibited conduct covered by the rule. Moreover, in secs. 202(a) and (b), Congress gave broad authority to the Secretary to establish the scope of Federal protections governing transactions in livestock and poultry, given the interstate nature of the industry.

According to the commenters, AMS's citation in this context suggests commercial feed yards are required to post bonds despite the case holding that they are not regulated entities and thus do not need to do so. A commenter further said this inaccurate citation, combined with the proposed rule's overbroad definition of “livestock producer,” suggests AMS is trying to regulate feed yards under the Act despite both Congressional intent and judicial precedent supporting their exclusion.

                         Live poultry dealers and poultry industry trade associations said Congressional authority for AMS to issue the proposed rule has expired because the agency did not promulgate it within the deadline set by the 2008 Farm Bill. A commenter said this Farm Bill included language asking GIPSA, the agency formerly in charge of implementing the Act, to promulgate new regulations dealing with several sections of the Act. The commenter noted that section 11006 of the 2008 Farm Bill tasked AMS with writing new regulations establishing criteria to determine four issues, including whether an undue or unreasonable preference or advantage has occurred in violation of the Act. Section 11006 included a timeline, requiring AMS to promulgate these new regulations no later than two years after the Farm Bill's May 22, 2008, enactment. However, AMS did not publish the proposed rule for comment until October 3, 2022, nearly 12 years after the Farm Bill deadline expired. According to the commenter, finalizing the proposed rule would therefore unconstitutionally exceed the scope of Congress's grant of authority to USDA.

Commenters said issues not covered under the Farm Bill grant include the introduction of a vague and ambiguous definition of “market vulnerable individual;” a determination that proof of anticompetitive harm is no longer necessary to prevail under secs. 202(a) or (b) of the Act; and regulation of deceptive practices and of recordkeeping.

                        <FTREF/>
                         Commenters argued that the Act has long been understood to be grounded in antitrust principles and has never in its hundred-year history been used to broadly address the kind of discriminatory conduct covered in the proposed rule. The commenters further claim that the proposed rule's treatment of the Act as an antidiscrimination statute also unprecedently extends past the scope of other such laws by targeting discrimination against independent contractors rather than employees.

                         They also note that, in addition to declining to apply the Act as an antidiscrimination statute, Congress has also declined to adopt any general prohibitions on discrimination in contracting extending beyond the ban on racial discrimination in 42 U.S.C. 1981. The commenters stressed that it would be the role of Congress, not AMS, to decide to apply the Act like an antidiscrimination statute. According to the commenters, specific aspects of the proposed rule that trigger this doctrine include the elimination of the harm-to-competition standard, the creation of a definition of “market vulnerable individuals,” the identification of conduct constituting deceptive conduct, and the 5-year document retention mandate for regulated entities.

                         As discussed in the preamble to this final rule, Congress enacted the Act after many years of concern about farmers and ranchers being cheated and mistreated. In the Act, Congress gave the Secretary broad authority to regulate the meatpacking industry. Congress believed that existing antitrust and market regulatory laws, including the Sherman Act and Federal Trade Commission Act, did not sufficiently protect farmers and ranchers. In the Act, Congress gave the Secretary broad authority to regulate the meatpacking industry. The House of Representatives' report on the Act stated that it was the “most comprehensive measure and extends farther than any previous law in the regulation of private business, in time of peace, except possibly the interstate commerce act.”

                    <P>This rule's interpretations of unjust discrimination, undue and unreasonable prejudice, and retaliation are consistent with longstanding approaches to protecting producers under the Act, are consistent with interpretations of similar provisions of sec. 5 of the FTC Act and the ICA, and mirror congressional policy as reflected in ECOA. Moreover, Congress as recently as 2008 directed USDA to conduct rulemakings on sec. 202, which led to the 2020 Rule discussed above on undue preferences. The 2020 Rule wrestles with questions of undue prejudices which this final rule settles. Deception similarly follows a long line of cases and rules covering deceptive practices under the Act. Regarding issues raised by commenters around the major question doctrine, this rule does not address political matters, nor does it focus on fixing purely economic harms. This rule aims to increase protections for producers by clarifying that secs. 202 (a) and (b) of the Act prohibit discriminatory, retaliatory, and deceptive conduct by regulated entities.</P>

                         Live poultry dealers and industry associations argued that the administrative record for the proposed rule fails to support a rulemaking. Commenters contended AMS has failed to identify any actual harmful conduct that would justify the proposed rule. Several commenters criticized specific aspects of the record, saying the court cases providing examples of alleged violations of the Act seem to be “opportunistically selected” and inaccurately cited, while the discussions of previous rulemaking efforts, many of which were withdrawn after Congressional objection, do not provide legitimacy. The commenters said, rather than basing its justification on facts, AMS instead acted arbitrarily and capriciously in supporting it with unverifiable anecdotal evidence and anonymous sources. A cattle industry trade association said that the proposed rule is too reliant on unexplained anecdotal evidence and suggested AMS has compounded this problem by encouraging commenters to respond anonymously.

                        A commenter said AMS aggravates these issues by inviting more anonymous feedback in its request for comment on the proposed rule, making it difficult to assess commenters' credibility, encouraging more false or unverifiable anecdotes, and further weakening the evidentiary foundation of the eventual final rule. The commenter urged AMS to reopen the comment period after clarifying that it will not give anonymous anecdotes disproportionate weight. Another commenter said, as AMS explicitly left racially discriminatory practices off its list of criteria for finding undue or unreasonable preferences under the Act in promulgating the final rule codified at 9 CFR 201.211,

                         AMS disagrees with commenters' argument that the administrative record for the proposed rule fails to support this rulemaking.

                         AMS gathered evidence from livestock producer and poultry grower testimonies, Congressional testimonies, DOJ and USDA public workshops, case law, and economic data. AMS has gathered economic data on disparities between white farmers and ranchers and other racial and ethnic groups. This data is presented in Figure 5 and highlights the need for this rulemaking to provide fair access to markets for all producers. Preliminary empirical results indicate that there are some systemic differences in prices received across ethnic/racial groups after accounting for regional fixed effects and marketing variables. Relative to White producers, historically underserved Black and American Indian groups receive lower cattle prices; Black groups receive lower contract broiler prices, and Black and American Indian groups receive lower hog prices.

                    <P>The provisions in this rule are basic, fundamental protections against discrimination on prohibited bases as authorized by the Act and as consistent with congressional policy. The prohibition on retaliation protects the ability for producers to communicate with governmental entities, associate, cooperate, and compete. The prohibitions on deception are equally basic. These basic and fundamental provisions are justified with the record presented. Decades of complaints by producers, include public hearings with the Department of Justice, have catalogued how vertical integration and market concentration have left producers unable to avoid adverse treatment that tends to exclude them from the marketplace, including retaliation preventing them from even reporting these concerns to governmental authorities. The result has been producers unable to bargain effectively in the marketplace or fully obtain the benefits of their livestock production and poultry grow out services. Regulated entities consistently assert they do not engage in such practices; if so, then the burdens from adopting this rule are low.</P>
                    <P>AMS is not reopening the comment period for this rule. Consistent with the Administrative Procedure Act, all interested persons had an opportunity to comment and the agency has considered all relevant matter received through the public comment process.</P>
                    <P>AMS does not agree that it has reversed its position with respect to the rationale underpinning the rule promulgating § 201.211. This final rule addresses undue and unreasonable prejudices and disadvantages and unjust discrimination. Conversely, the rule implementing § 201.211 addressed undue and unreasonable preferences and advantages. AMS may return to the question of undue and unreasonable preferences and advantages in future rulemaking but does not have at this time any further information to offer with respect to how AMS would or would not apply the Act's prohibition on undue or unreasonable preferences or advantages. AMS is not making any further changes in response to this comment.</P>

                         A cattle industry association said AMS has provided no meaningful evidence of discrimination on grounds other than race, saying evidence of the latter is unnecessary because racial discrimination in private contracting is already prohibited. According to the commenter, AMS also has provided no evidence that would justify its proposal to establish a broad market vulnerable producer approach to discrimination. This commenter also criticized AMS's citation of disparities in farm size and income along racial and ethnic lines. It said the agency confuses correlation and causation by arguing that smaller minority-owned farms necessarily have a harder time competing because of race discrimination when it has merely shown that minority-owned farms tend to be smaller and that any smaller farms tend to face competitive disadvantages compared to larger ones.

                         The existence of the continued correlation suggests the continued persistence of problems, and accordingly the need for additional clarity regarding the enforcement of the Act. To the extent that the activities covered are already prohibited, then the clarity provided by this rule should place no new burdens on industry with respect to compliance. Additionally, AMS has adopted in its final rule a list of prohibited bases for undue and unreasonable prejudice and disadvantages instead of using the term “market vulnerable,” therefore addressing commenters' concerns around the term's broadness.

                         suggests that certain ethnic or racial groups may be suffering currently from discrimination by packers in the establishment and/or performance of livestock and poultry contracts. Qualitatively, the research found consistent differences in prices received for livestock (cattle and hogs) and broiler products across ethnic or racial groups after controlling for variables such as farm size, regional differences, type of marketing contract or channel, organic certification status, distance to closest packer, and size of closest packer. Limitations of the study include that it is unable to control for all animal characteristics and cannot separate disparate economic outcomes arising from current racial discrimination from disparate economic outcomes due to historical discrimination.

                         A cattle industry association said the proposed rule is arbitrary and capricious because AMS has yet to release several related proposals dealing with rulemakings under the Act. The commenter notes that sec. 553(c) of the Administrative Procedure Act requires agencies to give interested parties a “reasonable” and “meaningful” opportunity to participate in the rulemaking, then argues that AMS's failure to disclose how this proposed rule will fit in with other related rules addressing poultry and livestock contractors under the Act does not meet this standard because it does not give parties a chance to respond to the rulemaking actions as a whole.

                         That previous rulemaking efforts, such as those published in 2016, tied multiple rulemakings together with respect to certain assumptions in their cost-benefit analysis is not dispositive on how this set of rulemakings—which are entirely different and unconnected to the 2016 effort—should be designed or presented for public comment. This final rule is a logical outgrowth of the rule as proposed and does not in any way depend upon what AMS may or may not propose or finalize in any other rules.

                         The commenter confuses the design of the rule. The specific protected activities set forth under § 201.304(b)(1) and (2) are narrowly tailored and limited to those delineated. In contrast, the forms of adverse conduct, as set forth in 201.304(b)(3), are inherently broader and more flexible. Additionally, the final rule provides greater specificity with respect to forms of adverse conduct, which are now delineated specifically and are no longer subject to open-ended addition.

                         Commenters argued that multiple provisions of the proposed rule are so vague and open-ended they thwart processors' ability to determine how it may apply to their conduct. According to the commenters, these provisions raise issues under the Fifth Amendment's Due Process Clause, which requires rules of law to define unlawful conduct with enough specificity to let interested parties understand what conduct is prohibited and to prevent arbitrary or discriminatory application of the rule.

                    <P>Live poultry dealers and a poultry industry trade association said the proposed rule is unconstitutionally vague because it includes a number of poorly defined or undefined terms for which failure to comply would result in a regulatory violation. The commenters said it provides only examples of behavior that would constitute a prohibited “prejudice or disadvantage” or “retaliation,” rather than spelling out definitive lists or definitions that regulated entities can use to comply with the proposed rule. The commenters highlighted other terms raising vagueness issues, such as “generally or ordinarily offered,” “differential contract performance or enforcement,” and “tak[ing] an adverse action.” These commenters said the rule also fails to spell out other concepts essential for identifying unlawful conduct, such as what would constitute a prohibited pretext or a legitimate explanation, how the recordkeeping requirements would be triggered, or what records must be kept. Commenters emphasized clear definitions are critical for companies to know what is and is not allowed under the rule.</P>

                         The Due Process Clause under the Fifth Amendment requires legal matters to be resolved according to established rules and principles. AMS has adequately described the type of conduct prohibited under this rule by expressly stating that prejudices on specified prohibited bases constitutes a violation under the Act. These prohibited bases expressly draw from ECOA and apply to the Act and are explained in this rule with the specificity required to give notice to interested parties as to what conduct is prohibited. Moreover, changes in this final rule more clearly delineate prohibited bases of discrimination in § 201.304(a)(1), prohibited prejudicial conduct under § 201.304(a)(2), prohibited retaliatory conduct under § 201.304(b)(3), and more. Concerns of vagueness are addressed by AMS further explaining terms in the final rule with the specificity needed to thwart claims of unconstitutional government action. The final rule also provides two new specific exceptions that address commenters' concerns regarding the proposed rule not including exceptions. Furthermore, as explained in response to earlier comments, the recordkeeping requirement is clear and specific in its explanation in requiring regulated entities to keep certain records pertaining to their business practices relating to activities subject to the jurisdiction of the Act.
                    </P>
                    <P>The terms used in this rule are intended to follow their plain language meaning, as applied to the livestock and poultry industries and within the legal framework regulating these industries. The following discussion demonstrates how these terms support the rule's prohibitions against undue prejudice, deception, and retaliation and in fact are quite specific.</P>
                    <P>“Retaliation” is set forth in paragraph (b)(3) and encompasses actions taken by regulated entities against covered producers such as contract termination, refusal to renew a contract, offering of more unfavorable contract terms than those generally or ordinarily offered, refusal to deal, interference with third-party contracts, and modification of contracts on less favorable terms than those previously enjoyed in response to the producer's participation in a protective activity. What constitutes retaliation is clearly defined in the rule, and likewise the rule clearly lays out protected activities against which retaliation is prohibited.</P>
                    <P>In this rule, “generally or ordinarily offered” terms are terms most producers would qualify for when contracting with a regulated entity. Whether terms are “generally or ordinarily offered” is an inquiry regarding specific facts and circumstances. Each case may vary by regulated entity and even for any given regulated entity may vary based on how the regulated entity would normally deal in the circumstances presented by the producer in question. However, “generally or ordinarily” does not apply to special contract terms that some regulated entities may use with certain producers, whether to receive particular quality attributes or services or for other reasons that are not discrimination on prohibited bases. The purpose of the rule is to ensure that a covered producer is not denied contract terms on the basis of a protected class that an “ordinary” similarly situated producer could receive from the regulated entity.</P>
                    <P>
                        “Performing under or forcing a contract differently than with similarly situated producers” refers to situations where a regulated entity operates in such a way that it denies a grower the full benefits to which it is entitled under its contract with the regulated entity. A poultry grower may seek to enforce a production contract term that gives the grower the right to receive appropriate feed for the grower's flocks on a timely basis in the event the grower regularly or at critical times experiences insufficient, delayed, or inappropriate feed. If a regulated entity threatens to terminate a grower's contract in response to the grower's efforts to enforce a particular contract term (a protected activity), this retaliatory conduct would violate the Act. AMS notes that this violation would be separate from any violation of contract law that may also exist. Another example is selective information disclosures. These often take the form of a regulated entity withholding materially relevant information from one covered producer that the regulated entity generally or ordinarily provides to other covered producers. In these instances, information-deprived producers will have an incomplete picture of their business relationships with regulated entities, and therefore will operate at an unreasonable disadvantage relative to producers who receive the pertinent information. 
                        <PRTPAGE P="16173"/>
                        Furthermore, this rule not only protects covered producers from such conduct in the form of retaliation. If a regulated entity engages in differential contract enforcement on the bases of a producer's protected class, this would constitute discriminatory conduct in violation of § 201.304(a) of this regulation.
                    </P>
                    <P>“Tak[ing] an adverse action” encompasses a range of prejudicial, deceptive, or retaliatory actions that unjustly inhibit market access such as prejudice, disadvantage, retaliation, deception, or any action that inhibits market access to producers. A range of actions taken by producers on legitimate business grounds can be adverse to producer welfare. However, in the context of this rule, adverse actions are those actions taken by regulated entities against producers that either unfairly discriminate against producers on the basis of a protected class, deceive producers, or represent retaliation against producers for engaging in protected activities such as lawful communications, assertion of contract rights, associational participation, or participating as a witness in any proceeding under the Act.</P>

                         A cattle industry trade association said the requirement to demonstrate harm to competition is crucial within its industry because packers differentiate cattle values using an array of different factors including production method, animal handling requirements, and program enrollment, meaning that seemingly similar lots of cattle may be valued substantially differently. The commenter expressed concern that the results of individual adjudications taking place under sec. 202 of the Act without the threshold of a competitive-injury requirement would vary significantly, diminishing innovation and product differentiation, confusing market participants, and ultimately harming both producers and consumers. A poultry industry trade association said that, if AMS seeks to establish circumstances in which conduct can violate secs. 202(a) and (b) without a showing of competitive injury, a separate standalone rulemaking would be more suitable than inclusion in the proposed rule.

                         This final rule solely addresses the prohibited conduct it covers—undue prejudice on prohibited bases, retaliation as unjust discrimination for engaging in protected activities, and certain forms of deception. It does not, beyond the specific prohibitions, interfere with the manner in which packers differentiate cattle values using an array of different factors including production method, animal handling requirements, and program enrollment, meaning that seemingly similar lots of cattle may be valued substantially differently. Individual adjudications with respect to the conduct covered by this proposed rule are essential to effectuate the prohibitions set forth in this rule, so as to eliminate in their incipiency occurrences of undue prejudice on prohibited bases and retaliation on protected activities.

                         USDA has previously explained that this consistently held position is based on the language, structure, purpose, and legislative history of the Act, and USDA continues to adhere to this longstanding position, despite the disagreement of some courts as to the relationship between harm to competition and violations under the Act.

                         Scope of Sections 202(a) and (b) of the Packers and Stockyards Act, 82 FR 48596 (Oct. 18, 2017), (reaffirming that “USDA has adhered to this interpretation of the P&amp;S Act for decades” and rejecting comments that this interpretation is not the USDA's longstanding position). Regardless, even if a showing of harm to competition were required for an undue prejudice or discrimination claim, the discriminatory practices prohibited in this rule would meet such a requirement. Discrimination and undue prejudice have no value or place in a competitive market, and in fact can lead to inefficiencies as personal characteristics, not production factors influence contracting decisions. Ultimately, the conduct at issue is squarely within the purposes of the Act. Where conduct “prevents an honest give and take in the market,” it “deprives market participants of the benefits of competition” and “impedes . . . a well-functioning market.” In its report on the 1958 amendments to the Act, the U.S. House of Representatives explained that the statute promotes both “fair competition and fair trade” and is designed to guard “against [producers] receiving less than the true market value of their livestock.” Discrimination and undue prejudice on the bases set forth in this final rule are both essentially unjust and undue as forms of unacceptable personal discrimination under the Act (drawing on similar precedent from the ICA and from P&amp;S Act implementation in stockyards), and also subvert normal market forces, undermine market integrity, and deprive producers of the true value of their products and services.

                         A legal foundation said the introduction of a recordkeeping requirement for processors may violate the due process clause by imposing unreasonable burdens on them and may exceed the limits of Federal enumerated powers under the Constitution. The commenter said that, although the Supreme Court upheld a recordkeeping requirement for banks against a due process challenge, the ruling was specific to entities receiving public funds and does not apply to regulated entities under the proposed rule. The commenter also contended such recordkeeping requirements generally lead to warrantless searches of businesses, and that these types of searches are only authorized for pervasively regulated, inherently hazardous industries, which likely does not apply to the meat or poultry industries.

                         AMS has authority under the Act to regulate certain entities and to promulgate rulemaking accordingly. The inclusion of a recordkeeping requirements serves the legitimate purpose to ensure compliance with this rule. Recordkeeping is regularly a component of rulemaking to ensure compliance and allow the regulating agency to better monitor impacts of the Rule. Regulated entities are already subject to a range of oversight by AMS subject to the longstanding application of the Act. Indeed, the Act already requires recordkeeping that fully and completely discloses the transactions by regulated entities of their poultry growing arrangements and transactions in

                         Although pervasive unjust discrimination has in the past kept outstanding producers from achieving their potential, AMS recognizes that adverse actions against producers commonly have several elements mixed in, some of which may include the discrimination or retaliation covered by this rule. AMS has set forth a standard causation standard: “because” and “on the basis of.” Further cause will be determined in the specific facts and circumstances of any enforcement matter. Those facts will determine whether AMS brings any particular matters and AMS expects unjust discrimination and retaliation to be the principal, or at least substantial, part of any decision by the regulated entity. Moreover, AMS is choosing not to require “sole” causation because doing so would undermine the effectiveness of the rule and encourage after-the-fact revisions of causation. Rather, AMS believes that regulated entities should have a heightened duty to eliminate unjust discrimination on the protected basis and retaliation for engaging in protected activities. To do so, boards of directors and chief executive officers may wish to establish clear corporate policies, adopt procedures to provide for heightened managerial supervision for circumstances where a close call may arise, and implement training across the corporate structure. “Tone at the top” should direct employees such that undue prejudice and retaliation are not acceptable forms of conduct, and when close calls arise, the regulated entity has taken every step reasonably possible to ensure that its conduct is focused solely on the merits of the producer's performance and the other competitive factors that the regulated entity must take into account when running its business. AMS made no changes to the final rule based on this comment.

                         A cattle industry trade association said that AMS has not yet made available its proposal for an additional related rule concerning section 202 of the Act, which must be considered alongside the current proposal. A meat industry trade association likewise cited AMS's anticipation of a “suite of major actions [. . .] to create fairer marketplaces for poultry, livestock and hog producers” and argued that AMS should withdraw the current proposal until the entire suite of proposals can be submitted holistically. Live poultry dealers and industry companies, a poultry industry trade association, and a swine industry trade association concurred that piecemeal updates to the Act would create challenges and confusion for regulated entities and producers. They suggested updating regulations collectively at one time.

                         AMS made no changes to the proposed regulations based on this comment. AMS appreciates the comments regarding the desire to view the rules holistically. However, AMS is under no obligation to make all potential rules available to the public simultaneously, regardless of their potential connection to components of this rulemaking. AMS is addressing issues in the livestock and poultry sector through its statutorily defined authority to administer the Act. Federal agencies commonly use separate rulemakings to address specific issues under their regulatory authority. As stated elsewhere, the authority or effect of this rule does not in any way depend upon the proposal or adoption of any other rules, proposed or not yet proposed. Accordingly, AMS made no changes based on this comment.

                         A cattle industry trade association noted that the proposed rule's preamble implied a strong relationship between concentration in the meatpacking industry and declining use of negotiated cash trades, with the further implication that the use of AMAs in place of cash trades has negatively impacted the market and rural economies. The commenter said that AMAs are not germane to the proposed rule and requested information on whether AMS intends the proposed rule to limit the ability of cattle producers to use AMAs. It argued that AMAs are critical to funding production of more sustainable and climate-friendly cattle production. In defense of AMAs, the trade association cited a 2021 Texas A&amp;M study finding that AMAs do not change underlying supply-and-demand fundamentals and so do not create market power

                         AMS acknowledges the commenters' concerns over the relationship between this rulemaking and the use of AMAs in the cattle industry. According to some in the industry, the growth of these vertical contracting relationships in the context of highly concentrated markets has led to concerns that firms have greater control over producers and thus have more ability to abuse their market power, impede producer choices, exclude some market participants, and coerce producers unwittingly into inefficient farm decisions. This rule prohibits prejudices on certain protected bases that tend to exclude or disadvantage covered producers in those markets; identifies retaliatory practices that interfere with lawful communications, assertion of rights, and associational participation, among other protected activities, as unjust discrimination prohibited by the law; and identifies deceptive practices that violate the Act with respect to contract formation, contract performance, contract termination, and contract refusal. AMS sees no manner in which this regulation affects the general existence or use of AMAs. Therefore, AMS has made no changes to the regulations in response to this comment.

                         AMS appreciates this commenter's suggestion to further educate producers and will take this under consideration as additional support AMS may offer to producers. This rulemaking action clarifies that if regulated entities make omission of material information necessary to make a statement or representation not false or misleading (as defined in the rule) against a covered producer, such conduct amounts to deception and is a violation of the Act. The codification of these regulations stems from existing law that aims to prohibit deception in Act-regulated markets. The new regulations do not create any specific disclosure of information requirements. To the extent that regulated entities identify the need to provide additional information to producers, the facts and circumstances of the transaction will determine whether the information is in violation of the rule. AMS agrees that producer education and outreach are valuable to protecting producers and effectuating the purpose of the Act and intends to conduct more of such activities in the immediate term. AMS is making no changes to the regulations as proposed in response to this comment.

                         Section 201.304(c) will require live poultry dealers, swine contractors, and packers to retain all relevant records relating to their compliance with § 201.304(a) and (b) for no less than five years. This recordkeeping requirement is necessary to evaluate compliance with § 201.304(a) and (b) and to facilitate investigations and enforcements based on producer and grower complaints. This recordkeeping requirement will bolster AMS's ability to review the records of regulated entities during compliance reviews and investigations based on complaints of undue prejudices, unjust discrimination, and retaliation in the livestock and poultry industries in accordance with the purposes of the Act. Costs of recordkeeping include maintaining and updating records by regulated entities and will be discussed and quantified below.

                         Costs to comply with the recordkeeping are likely relatively low. This rule extends the disposal date of most records, if already kept, from 2 years to five years to promote efficient USDA monitoring efforts. For some records, the current disposal date is 1 year, which could be extended to five years under this rule if they are deemed relevant to showing compliance with this rule. Costs of recordkeeping include regulated entities maintaining and updating compliance records they already keep. From the perspective of the regulated entity, recordkeeping is a direct cost. Some smaller regulated entities that currently do not maintain records may voluntarily decide to develop formal policies, procedures, training, etc., to comply with the rule and will then have records to maintain.
                    </P>
                    <P>AMS expects the recordkeeping costs will be comprised of the time required by regulated entities to store and maintain records they already keep. AMS expects that the costs will be relatively small because some packers, live poultry dealers, and swine contractors may currently have few records concerning policies and procedures, staff training materials, materials informing covered producers regarding reporting mechanisms and protections, compliance testing, board of directors' oversight materials, and the number and nature of complaints received related to unduly prejudicial and unjustly discriminatory treatment. Some firms might not have any records to store. Others already store the records and may have no new costs.</P>
                    <P>
                        The amount of time required to keep records was estimated by AMS subject matter experts. These experts were auditors and supervisors with many years of experience in AMS's PSD conducting investigations and compliance reviews of regulated entities. AMS used the May 2022 U.S. Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics for the time values in this analysis.

                         BLS estimated an average hourly wage for general and operations managers in animal slaughtering and processing to be $61.24. The average hourly wage for lawyers in food manufacturing was $103.81. In applying the cost estimates, AMS marked-up the wages by 41.79 percent to account for fringe benefits.

                        AMS expects that recordkeeping costs will be correlated with the size of the firms. AMS ranked packers, live poultry dealers, and swine contractors by size and grouped them into quartiles, estimating more recordkeeping time for the largest entities in the first quartile than for the smallest entities in the fourth quartile. The first quartile contains the largest 25 percent of entities, and the fourth quartile contains the smallest 25 percent of entities. AMS estimated that § 201.304(c) will require an average of 4.00 hours of administrative assistant time, 1.50 hours of time each from managers, attorneys, and information technology staff for packers, live poultry dealers, and swine contractors in the first quartile to setup and maintain the required records in the 
                        <PRTPAGE P="16176"/>
                        first year. AMS expects the packers, live poultry dealers, and swine contractors in the second quartile will require an average of 2.00 hours of administrative assistant time, 0.75 hours of time each from managers, attorneys, and information technology staff for first year costs. The third quartile will require 1.33 hours of administrative assistant time, 0.50 hours of time each from managers, attorneys, and information technology staff for first year costs, and the fourth quartile will require 0.67 hours of administrative assistant time, 0.25 hours of time each from managers, attorneys, and information technology staff.

                    <P>AMS also expects that packers, live poultry dealers, and swine contractors will incur continuing recordkeeping costs in each successive year. AMS estimated that § 201.304(c) will require an average of 3.00 hours of administrative assistant time, 1.50 hours of time each from managers, attorneys, and 1.00 hour of time from information technology staff for packers, live poultry dealers, and swine contractors in the first quartile to setup and maintain the required records in each succeeding year. AMS expects that packers, live poultry dealers, and swine contractors in the second quartile will require an average of 1.50 hours of administrative assistant time, 0.75 hours of time each from managers, attorneys, and 0.50 hours of time from information technology staff in each succeeding year. The third quartile will require 1.00 hour of administrative assistant time, 0.50 hours of time each from managers, attorneys, and 0.33 hours of time from information technology staff in each succeeding year, and the fourth quartile will require 0.50 hours of administrative assistant time, 0.25 hours of time each from managers, and attorneys, and 0.17 hours from information technology staff.</P>

                        This section describes the need for the regulatory action, and how the regulatory action will meet this need. The structure of the livestock and poultry industries sets the stage for unjustly discriminatory and deceitful conduct by regulated entities. This rule aims to benefit covered producers by protecting their rights from these market harms. This regulatory action addresses market failure in the livestock and 
                        <PRTPAGE P="16177"/>
                        poultry industries. This section will show how high levels of concentration, the prevalence of vertical contracting, asymmetry of information and the hold-up problem together create an environment facilitating abusive conduct that this rule addresses and defines the need for this rule. Discriminatory practices are the exclusionary or adverse treatment which market concentration and vertical contracting makes possible and hard to avoid on the basis of a covered producer's race, or other protected basis, and on the basis of actions that prejudice, disadvantage, inhibit market access, or are otherwise adverse compared to terms generally or ordinarily offered to similarly situation covered producers. This rule focuses on prohibiting regulated entities from wrongfully excluding producers from markets or denying those producers the full value of their products or services in those markets. It will then be shown how the livestock and poultry market structures help define the distribution of this rule's costs and benefits.

                    <P>The rise of concentration and vertical contracts in livestock and poultry markets has increasingly created an environment that enables packers, swine contractors, and live poultry dealers to unjustly exclude many producers from, and otherwise undermine their economic opportunities in, the marketplace.

                        Concentration in these markets has intensified over the past several decades and continues today. Concentration ratios are one metric to track the increasing share of slaughter of livestock and poultry in U.S. attributed to fewer packers and poultry integrators. Table 1 in the 
                        <E T="03">Background</E>
                         section shows the level of concentration in the livestock and poultry slaughtering industries for 1980-2020 using four-firm Concentration Ratios (CR4). The CR4 for steers and heifers was 36 percent in 1980 and rose to 81 percent in 2020. That is, in 2020, the top four beef packers slaughtered 81 percent of the nation's steers and heifers. The CR4 for hogs was 32 percent in 1980 and rose to 64 in 2020, and the CR4 was 32 percent in 1980 for broilers and rose to 53 percent in 2020.

                        The data in Table 1 are estimates of CR4s at the national level; however, in practice, the relevant economic markets for livestock and poultry may be regional or local, where concentration may be higher than those at the national level. This is because of limits on how far live animals can be safely and efficiently transported. In particular, regional concentration is often higher than national concentration for hogs.

                         Similarly, based on AMS's experience conducting investigations and monitoring cattle markets, there are often only one or two cattle buyers in many local geographic markets, and very few sellers have the option of selling fed cattle to more than three or four packers. Likewise, even though poultry markets are the least concentrated of the four markets described above as measured by their national CR4s, relevant markets for poultry growing services are more localized than markets for fed cattle or hogs, and local concentration in poultry markets is often greater than the national concentration level. Thus, the current environment is one where producers have little choice in whom they do business with, resulting in an unequal distribution of bargaining power between parties. MacDonald and Key found that about one quarter of contract growers reported that there was just one live poultry dealer in their area, defined by a roughly 34-mile radius from their farm; another quarter reported two; another quarter reported three; and the rest reported four or more.

                         highlights this issue by using the Herfindahl-Hirschman Index (HHI) to show the limited ability of poultry growers to switch to different integrators. Similar to a CR4, HHI is an indicator of market concentration, with the index increasing as market shares across firms (packers) become more unequal or the number of these firms decrease. Markets with HHIs above 2,500 are considered highly concentrated. Table 2 presented earlier from MacDonald showed that 88.4 percent of growers face an integrator HHI of at least 2,500. As stated earlier, the data suggest that most contract broiler growers in the U.S. are thus in markets where the sellers have the potential for market power advantage. Livestock producers face similar market vulnerabilities as shown here for poultry growers given that livestock producers also face regional market concentration that is more concentrated than national data would indicate.

                    <P>Market concentration and the use of vertical contracts are interrelated; as such, growing, production, and marketing contracts feature prominently in the livestock and poultry industries. As outlined above, several provisions in §§ 201.304 and 201.306 will affect the process of contract formation, performance, termination, and any other action that a reasonable covered producer would find materially adverse for livestock, poultry, and meat grown or marketed.</P>
                    <P>The type of contracting varies among cattle, hogs, and poultry. Broilers, the largest segment of poultry, are almost exclusively grown under production contracts, in which the live poultry dealers, a regulated entity, own the birds and provide poultry growers with feed and medication to raise and care for the birds until they reach the desired market size. Poultry growers provide the housing, the skill and labor, water, electricity, fuel, and provide for waste removal. Fed cattle marketing contracts typically take the form of marketing agreements. Hog production falls between these two extremes.</P>
                    <P>As shown in Table 5 below, over 96 percent of all broilers and over 42 percent of all hogs are grown under contractual arrangements. Similar to poultry contracts, swine contractors typically own the slaughter hogs and sell the finished hogs to pork packers. The swine contractors typically provide feed and medication to the swine production contract growers who own the growing facilities and provide growing services. The following table shows that the percentage of contract growing arrangements by species has remained relatively stable between 2007 and 2017.</P>

                         of contracts include marketing agreements and forward contracts. Under marketing agreements and forward contracts, producers and packers agree to terms on a future sale and purchase of livestock. These types of agreements and contracts are commonly referred to as AMAs. Pricing mechanisms vary across AMAs. Some AMAs rely on a reported spot, or negotiated, market price or exchange-based futures price for at least one aspect of its price, while others involve complicated pricing formulas with premiums and discounts based on carcass merits. The livestock producer and packer agree on a pricing mechanism under AMAs, but usually not on a specific price.

                    <P>AMS reports the number of cattle sold to packers under formula, forward contract, and negotiated pricing mechanisms. Table 6 illustrates the prevalence of contracting in the marketing of fed cattle. Formula pricing methods and forward contracts are two forms of AMA contracts. Thus, the first two columns in the following table are cattle marketed under contract and the third column represents the spot market, or negotiated market, for fed cattle including negotiated grid. The data in the below table show that the AMA contracting of cattle has increased since 2010. Approximately 55 percent of fed cattle were marketed under contracts in 2010 (formula and forward contracts in the below table). By 2021, the percentage of fed cattle marketed to packers under AMA contracts had increased to just over 72 percent. These data also show the declines in the percentage of cattle sold on the spot market, or negotiated trades, from 46 in 2010 to 28 in 2021.</P>

The spot market, or negotiated trades, for hogs has declined from 5.2 percent in 2010 to 1.5 percent in 2020. As these data demonstrate, almost all hogs are marketed to packers under some type of marketing contract.

                        Despite various policy and public concerns, contracting, growing, production, and marketing contracts can offer certain benefits to the contracting parties. Properly tailored, benefits can include helping farmers, livestock producers, and processors manage price and production risks, elicit the production of products with specific quality attributes by tying prices to those attributes, and facilitate the smooth flow of commodities to processing plants. Such attributes may encourage certain efficiencies in use of farm and processing capacities. Quality-related attributes and standards can incentivize farmers to deliver products that consumers desire and produce products in ways that reduce processing costs.

In concentrated industries, like the cattle, hog, and poultry industries, where market power is present, these types of contracts may result in increased opportunities for undue prejudices and unjust discrimination, retaliation, and deception, among other concerns, which cause inefficiencies in the markets for livestock, poultry, and meat.

                         Heightened market concentration implies that livestock producers and poultry growers face fewer marketing and contract options compared to less concentrated markets. Livestock producers and poultry growers may find themselves in a take-it-or-leave it situation when a new or renewal contract is presented due to a limited number of packers and live poultry dealers with which to contract. Thus, livestock producers and poultry dealers entering into new, or renewal contracts may be taken advantage of through discriminatory, deceptive, or retaliatory practices.

                        Livestock and poultry contracts may lead to unjust, prejudicial, and retaliatory practices. For example, a contract that limits a poultry grower's services to a single integrator, even if the contract provides for fair compensation to the grower, still leaves the grower subject to risks. The grower faces the risk that the contractor may require additional capital investments or the contractor may impose lower returns at the time of contract renewal—leveraging its market power given the grower's limited options.

                         Some poultry make substantial long-term capital investments as part of livestock or poultry production contracts, including land, poultry or hog houses, and equipment. Those investments may bind the grower to a single contractor or integrator, furthering the indebtedness and exacerbating an imbalance of power.

                    <P>In the poultry industry, limited integrator choice may accentuate contract risks. The data in Table 2 above show that 52 percent of broiler growers, who account for 56 percent of total production, report having only one or two integrators in their local areas. Even where multiple integrators are present, there are high costs to switching, owing to the differences in technical specifications that integrators require. The growers likely need to invest in new equipment and learn to apply different operational techniques due to different breeds, target weights, and grow-out cycles.</P>
                    <P>
                        A 2006 survey indicated that growers with access to a single integrator received seven to eight percent less

                        In the cattle sector, cow-calf operations incur a significant investment in breeding stock and typically sell steers and heifers once a year. Access to competitive markets, absent from unjust discrimination, undue prejudice, and retaliation, is important to the economic livelihood of the market. Reduced marketing options—fewer options to sell on the spot market, or lack of access to contracts—can leave producers susceptible to unfair trade practices. Spot market trades, or negotiated trades, as opposed to marketing agreements or contracts, for fed cattle accounted for 51 percent of all trades in 2008 and fell to 29 percent in 2022.

                         Market concentration facilitates the exclusionary and adverse treatment observed in discriminatory practices. The data in Table 1 are estimates of national four-firm concentration ratios at the national level, but the relevant economic markets for livestock and poultry may be regional or local, and concentration in the relevant market may be higher than the national level. For example, while poultry markets may appear to be the least concentrated in terms of the four-firm concentration ratios presented above, relevant economic markets for poultry growing services are more localized than markets for fed cattle or hogs, and local concentration in poultry markets is often greater than in hog and other livestock markets. The data presented earlier in Table 2 highlights this issue by showing the limited ability a poultry grower has to switch to a different integrator. As a result, national concentration may not demonstrate accurately the options poultry growers in a particular region face.

                    <P>The levels of industry concentration shown in Tables 1 and 2 may contribute to oligopolistic market power and asymmetric information.

                    <HD SOURCE="HD3">The Need for the Rule: Asymmetric Information</HD>
                    <P>
                        There is asymmetry in the information available to livestock producers and livestock and poultry growers as compared to the packers, swine contractors, and live poultry dealers with whom they contract. The larger packers, swine contractors, and live poultry dealers generally have more information (costs of production, input quality, and consumer demand, for example) that is useful in contracting than the smaller livestock producers and livestock and poultry growers. This asymmetry of information can lead to deceptive practices by regulated entities with superior information in contract formation, performance, termination, or refusal by employing a false or misleading statement, or omission of material information necessary to make a statement not false or misleading. A 2023 AMS rule, Transparency in Poultry Grower Contracting and Tournaments, directly aims to address this asymmetric information in the poultry industry by adding disclosures and information that live poultry dealers engaged in the production of broilers must furnish to poultry growers with whom dealers make poultry growing arrangements.

                        Most growers producing poultry under production contracts are paid under a poultry grower ranking or “tournament” pay system. Under tournament systems, the contract between the poultry grower and the company for whom the grower raises poultry for slaughter pays the grower based on a grouping, ranking, or comparison of poultry growers delivering poultry to the same company during a specified period. Generally, live poultry dealers provide most of the inputs to all the growers in each poultry tournament used to determine grower pay. In these tournaments, the live poultry dealers have information about the quality of the inputs, while each grower only knows what he or she can observe. A grower may not be able to evaluate the inputs it received such as chicks and feed, and he or she almost certainly will not know about the inputs received by other growers. A live poultry dealer also has historical information concerning growers' production and income under many

                        different circumstances for all the growers with which the dealer contracts, while an individual grower, like most other producers, only has information concerning his or her own production and income. Prohibiting deception may serve to reduce the negative impacts from asymmetric information. Prohibiting retaliation against producers or growers because they joined a cooperative or grower association organization, shared information to improve their production or growing practices with a regulated entity, another covered producer, or with a commercial entity, communicated with the government, or asserted any of the rights granted under the Act should lead to reducing the information asymmetry between regulated entities and producers.
                    </P>
                    <HD SOURCE="HD3">The Need for the Rule: Hold-Up Problem</HD>
                    <P>Hold-up is another problem that is particularly acute in service contracts between poultry growers and live poultry dealers. The economic concept of a hold-up problem refers to a situation in which two parties may be unable to cooperate efficiently due to incomplete or asymmetric information and the inability to write, enforce, or commit to contracts. Once a party becomes locked into a transaction, especially as a result of making a transaction-specific investment, they become vulnerable to exploitation by the other party. This may involve one party to a contract opportunistically deviating from expectations of the other party or failing to live up to previously agreed upon terms.</P>
                    <P>In the poultry industry, hold-up occurs when a poultry grower makes an investment, such as in poultry housing, and becomes dependent upon the growing arrangement to repay the investment. Hold-up is less common for hog and cattle producers, so the discussion here is limited to poultry growing to highlight this risk to poultry growers. Substantial gaps exist between the periods of time covered by the contract and the mortgage on poultry housing, creating uncertainty around whether growers will be able to repay their debt and recoup their investments, introducing the potential for hold-up into the contracting process. If the integrator takes advantage of the grower's dependence, for example, by delaying delivery of chicks that the grower depends upon to make payments on investments, it would be holding up the grower. The aim of the economic hold-up may be to coerce the grower into accepting conditions that benefit the integrator at the expense of the grower. For example, refusing to supply chicks until a contract amendment with unfavorable conditions is signed.</P>
                    <P>This is of concern in poultry production contracts because the capital investment requirements related to growing chickens are significant and highly specialized (that is, they have little value outside of growing chickens). As a result, growers entering the market are tied to growing chickens to pay off the financing of the capital investment. Growers have reported that they must accept unfavorable contract terms or endure unfavorable treatment during a contract—including inappropriate limits on their ability to form associations, assert their rights under the law or contract (such as viewing the weighing of broilers), communicate with government entities, and seek alternative business relationships—because they are tied to production to pay off lenders and they have few, if any, alternative integrators with whom they can contract. Hog producers, which invest heavily in production facilities, may face similar risks.</P>
                    <P>Long term, this behavior may result in underinvestment in production, which is inefficient. Alternatively, if growers make a significant investment because they do not anticipate hold-up, but then it does occur, then growers may be required to spend too much on investments. The resulting over-investment in capital by those growers facing hold-up is also inefficient. The hold-up problem is a manifestation of both market power and asymmetric information.</P>
                    <HD SOURCE="HD3">Summary Need for the Rule: Contracting, Industry Structure, and Market Failure</HD>
                    <P>As described previously, the organization and structure of poultry and livestock markets is characterized by regional market power; substantial investment in production capital that is specific to a single production purpose; and, in the poultry industry, nearly universal use of production contracts, and widespread use of marketing contracts in the cattle industry, while less so, for hogs. These conditions create the potential for market failures. Asymmetric information and imperfect competition are concerns in livestock and poultry markets. economically incomplete contracts and hold-up are of particular concern in poultry markets and can exacerbate the risk of undue prejudice and unjust discrimination, retaliation, and deception in poultry and livestock markets.</P>
                    <P>By setting forth specific prohibitions on unduly prejudicial and unjustly discriminatory and deceptive practices, the rule will reinforce producers' existing rights to gather and share information, while reducing the fear of retaliation and interference in the contracting process. The prohibitions in the rule will also continue to support, and possibly promote more efficient and equitable information access, reduce the hold-up problem, reduce retaliation, discourage false and misleading statements, and increase communication, cooperation, and retention of legal rights. The prohibitions specified in §§ 201.304 and 201.306 will ultimately assist in mitigating the impacts of imperfect competition.</P>

                    <P>As discussed above, final § 201.304 prohibits undue prejudice, unjust discrimination, and retaliation by regulated entities and adds a requirement for regulated entities to maintain records that they already keep, for up to a period of five years, related to its compliance with final § 201.304. Section 201.306 will prohibit deceptive practices by regulated entities in contract formation, performance, or termination by employing a false or misleading statement, or omission of material information necessary to make a statement not false or misleading. Additionally, a regulated entity may not refuse a contract by providing false or misleading information to a covered producer or associations of covered producers.</P>
                    <HD SOURCE="HD3">Final Rule: Benefits</HD>
                    <P>Reductions in prejudicial, discriminatory, retaliatory, and deceptive practices by packers, swine contractors, and live poultry dealers will benefit society. These types of conduct are inefficient, and often difficult to quantify for prejudicial, discriminatory, retaliatory, and deceptive practices are not necessarily written into contracts but in contract offers, preparation and enforcement. Production contracts need not change to realize benefits in this rule. The amount of benefits that depends on the extent to which the rule reduces prejudicial, discriminatory, retaliatory, and deceptive practices. That, in turn, is bounded by the degree to which any of these types of activities are occurring in the baseline. If the reductions are small, the benefits will be small. The greater the reductions, the greater the potential benefits. USDA's long-standing policy has been that the Act prohibits the type of conduct that final §§ 201.304 and 201.306 addresses.</P>
                    <P>
                        Final §§ 201.304 and 201.306 add specificity to what constitutes undue prejudices, unjustly discriminatory practices, retaliation, and deception. The size of the benefits is difficult to quantify as it depends on the amount of undue prejudice, unjust discrimination and deception that will be avoided due to added specificity provided by the rule. The added benefits to the industry from final §§ 201.304 and 201.306 over the

                         occur when packers, swine contractors, and live poultry dealers alter their conduct to reduce instances of deceptive, prejudicial, and discriminatory practices, including retaliation. The potential benefits include protecting producer and grower rights, improved corporate culture, improved information, fewer deceptive practices, among others. The more undue prejudice, unjust discrimination, retaliation, and deception that will be avoided, the larger the benefits. AMS is unable to quantify the benefits and will present a qualitative discussion of the types of potential benefits that accrue from reductions in undue prejudice, unjust discrimination, retaliation, and deception.

                    <HD SOURCE="HD3">Benefits: Protecting Producer and Grower Rights</HD>
                    <P>A key purpose of specifying certain prohibitions on unduly prejudicial, discriminatory, and deceptive practices, including those in final §§ 201.304 and 201.306, is to protect livestock producers, swine contractors and poultry growers' rights under the Act. Final §§ 201.304 and 201.306 will also help protect producers from unfair and deceptive practices stemming from market power imbalances such as undue prejudice, unjust discrimination, retaliation, and deception by using false or misleading statements in contracting by packers and live poultry dealers. The benefits of prohibiting prejudicial, discriminatory, and deceptive practices, will accrue not only to the market's covered producers and cooperative producers who have been subjected to the prohibited practices, but also to those for whom the rule's deterrence effects will protect from future potential abuses.</P>
                    <HD SOURCE="HD3">Benefits: Addressing Imperfect Information</HD>
                    <P>Several provisions in the final rule will enhance the protection of the rights of producers to lawfully communicate and to associate with others to explore business relationships and improve production practices and in the marketing of livestock, poultry, and meat. These provisions will benefit producers by encouraging the use of their currently existing legal rights that will solidify and enhance their access to information. This in turn will help address information asymmetry and thus help producers make better business decisions, enhance their competitiveness, reduce the hold-up problem, and promote innovation and economic efficiency in the industry.</P>
                    <P>The final rule will help close this information gap by protecting the rights of producers to form associations and communicate freely with one another, and to communicate with other regulated entities for the purpose of exploring a business relationship. This will benefit producers by improving their ability to strengthen the returns to their livestock and poultry investments, by enhancing the bargaining power of supplier groups if they elect to organize in such a way.</P>
                    <P>This rule will prohibit retaliation against covered producers due to their communicating, negotiating, or contracting with other covered producers, a commercial entity, consultant, or regulated entities, which could increase the important decision-making information available to producers. Improved safeguarding of protected activities may enable the producer to improve business decision-making and manage risk, including potentially acquiring external insurance and risk-management products. In addition, facilitating producers' ability to gain more and better information will help correct information asymmetry and improve transparency and completeness in contracts.</P>
                    <P>More information will also reduce the risks associated with hold-up as discussed above. By protecting rights to freely communicate and associate, this rule will facilitate communication across the industry that may help disseminate information regarding new innovations and best practices within the industry. These types of provisions that could provide producers with access to more and better information should promote innovation and economic efficiency in the industry.</P>
                    <P>The final rule may also serve to reduce the risk of violating sec. 202(a) of the Act because it will provide clarification to the livestock, and poultry industries as to the discriminatory and deceptive practices that will be prohibited under that section of the Act. Less risk through the clarification provided in the final rule will likely foster fairness in contracting by providing explicit protections for livestock producers, swine production contract growers, and poultry growers.</P>

                        Final § 201.306 specifies prohibited practices that will be considered deceptive, and thus in violation of sec. 202(a) of the Act. Though USDA already protects producers from deceptive practices, the rule will explicitly protect suppliers from deception by packers and live poultry dealers by employing a false and misleading statement, or omission of material information necessary to make a statement not false or misleading in contracting. Prohibited deceptions, including false statements or omissions, can prevent or mislead producers, sellers, or buyers from making informed decisions and thus

                        represents a market inefficiency. The provisions in final §§ 201.304 and 201.306 will help give producers confidence that the information provided by processors is reliable, which will help them to make better and more informed business decisions and manage risk.

                    <P>
                        While some of these protections already benefit individual producers, ensuring they cover the full marketplace and can be enforced individually adds to the integrity and fairness of livestock and poultry contracting. Specifying these protections may bring additional benefits above the

                         Alternative.
                    </P>
                    <P>Production and marketing contracting has many benefits in the livestock and poultry industries. The final rule can further enhance the documented benefits of contracting by prohibiting unduly prejudicial, discriminatory, and deceptive practices. Livestock producers often have few choices of packers to which they sell, and poultry growers often have few choices in the live poultry dealers for which they raise poultry. The limited alternatives cause fear among producers that certain actions they might undertake, such as communication with government or other regulated entities to pursue business relationships, association with certain groups, or making lawful public complaints about the packers, swine contractors, or live poultry dealers might result in harmful retaliations. AMS intends the final rule to promote integrity to the marketplace by enhancing the protection of the rights of the producers and alleviating those fears.</P>
                    <P>
                        The literature and data on these topics are not sufficient to allow AMS to estimate the magnitude of the inefficiencies that the final rule may correct above the

                         Alternative, nor the degree to which the additional producer and grower protections will address inefficiencies. Though AMS is unable to quantify the benefits of the regulation, this analysis has explained the types of benefits that will be derived from reductions in undue prejudice, unjust discrimination, retaliation, and deception. If the reductions are small, the benefits will be small. The greater the reductions, the greater the potential benefits.

                    <HD SOURCE="HD3">Final Rule: Costs</HD>
                    <P>The final rule will not impose any restrictions on numbers or types of production or marketing contracts that can be utilized, use of AMAs, poultry tournaments, or base price mechanisms in contracts for packers, swine contractors, and live poultry dealers. Instead, the final rule clarifies the prohibited unduly prejudicial, unjustly discriminatory, and deceptive practices that AMS considers violations of sections 202(a) and (b) of the Act. The final rule will require packers, live poultry dealers, and swine contractors to discontinue any prejudicial, unjustly discriminatory, or deceptive practices, if any are occurring. The practices prohibited by §§ 201.304 and 201.306 are the kind of practices that do not benefit society as a whole, but there is uncertainty about the extent of net costs to regulated entities of preventing them since they are based on behaviors and are not expressly written into contracts. In other words, §§ 201.304 and 201.306 result in uncertain-in-magnitude indirect costs resulting from adjustments by the livestock and poultry industries to reduce their use of AMAs, poultry tournaments, and pricing mechanisms, with the possibility of a number of changes to existing marketing or production contracts.</P>
                    <P>
                        Though the magnitude of indirect costs is uncertain, AMS has constructed a scenario that indicates the magnitude is likely below an established dollar value benchmark. The following scenario illustrates why it is extremely unlikely that the rule's indirect costs will exceed the Unfunded Mandates Reform Act's (UMRA) cost compliance threshold of $170 million annually, a benchmark used to assess this rule's effects on the private sector.

                         If some cattle contracts are altered to come into compliance with the rule, and cattle prices to some producers are increased, AMS expects that the packers will offer, at most, the average price paid for cattle. Looking just at cattle, the weighted average difference between the minimum and average liveweight prices paid for cattle over the last nine years in four cattle regions reported by AMS Market News is $1.31 per cwt ($.01/lb.).
                        <SU>278</SU>
                        <FTREF/>
                         If AMS assumes that the entire difference between the minimum and average prices paid was due to unlawful discrimination, deception, and retaliation, this will require 13 billion pounds of liveweight cattle to meet the $170 million threshold.
                        <SU>279</SU>
                        <FTREF/>
                         This assumption does not account for any price differences for cattle related to quality of the animal. Taking the 2022 average liveweight per head for all cattle of 1,369 lbs. per head,

                        <FTREF/>
                         this means that 9.5 million head of cattle in one year would have to face conduct this rule aims to prohibit to equal $170 million in costs in that year.
                        <SU>281</SU>
                        <FTREF/>
                         This number accounts for 28 percent of all cattle slaughtered in 2022.

                        <FTREF/>
                         Based on AMS's knowledge of the livestock industry, it is not expected that the number of cattle affected by unlawful discrimination, retaliation, or deception reaches this level. This fact, combined with the unrealistic assumption that any price deduction below the average price does not account for quality differences and is wholly the result of discrimination, retaliation, and deception, points to a conclusion that this rule will have limited impacts, and not exceed the UMRA threshold.

                    <P>
                        AMS expects §§ 201.304 and 201.306 to reduce litigation costs due to increased compliance with the rule associated with the clarity provided by the rule as to the conduct that violates the Act, but also to increase litigation as this rule allows producers to find relief in courts. AMS is uncertain as to which of these offsetting effects will dominate and to what extent. The final rule clarifies the prohibited unduly prejudicial, discriminatory, and deceptive practices that will violate section 202(a) of the Act. The clarification could result in a reduction in litigation costs if companies come 
                        <PRTPAGE P="16184"/>
                        into compliance without any enforcement action. These regulations encourage regulated entities to proactively avoid prejudicial, discriminatory, and deceptive practices that could otherwise lead to costly litigation. Further, some firms may develop policies and procedures to comply with the recordkeeping requirements. This effect could reduce litigation and thus result in reduced litigation costs for regulated entities.
                    </P>
                    <P>However, there are several provisions in § 201.304 that could result in additional litigation. AMS has received formal and informal complaints against packers, swine contractors, and live poultry dealers for retaliation for belonging to various producer and grower associations, contacting AMS to file a complaint, asserting legal rights, and contacting a competing regulated entity to pursue a contractual relationship. Similarly, there are several provisions in § 201.306 that could result in additional litigation, including refusals by regulated entities to enter into or renegotiate contracts and contract terminations by producers. The clarity of the practices that AMS considers to be discriminatory and deceptive in §§ 201.304 and 201.306 could offer producers new hope for relief from courts for undue prejudicial, discriminatory, and deceptive practices by regulated entities. This effect could result in increased litigation.</P>
                    <P>As stated above, AMS is uncertain as to which effect will dominate and to what extent. AMS does not estimate litigation costs in this analysis.</P>
                    <HD SOURCE="HD3">Direct Costs of the Final Rule</HD>
                    <P>AMS expects §§ 201.304 and 201.306 will result in direct administrative and recordkeeping costs to the industry. AMS expects that packers, swine contractors, and live poultry dealers will incur direct administrative costs of learning the rule and then reviewing and, if necessary, revising marketing and production contracts to ensure compliance with §§ 201.304 and 201.306. Regulated entities will also incur recordkeeping costs from keeping the records they already maintain for up to five years as required under § 201.304. The expected total costs of §§ 201.304 and 201.306 will be the direct administrative costs and recordkeeping costs of that regulatory alternative. The direct administrative costs and recordkeeping costs will be estimated below.</P>
                    <HD SOURCE="HD3">Direct Administrative Costs of the Final Rule</HD>
                    <P>AMS expects that §§ 201.304 and 201.306 will prompt packers, live poultry dealers, and swine contractors to first review and learn the rule and then review their procurement policies and production contracts and make any necessary changes to ensure compliance with the new regulations. Expected costs are estimated as the total value of the time required to review and learn the rule and then review and, if necessary, revise procurement and production contracts.</P>
                    <P>AMS expects the direct administrative costs of complying with §§ 201.304 and 201.306 will be relatively small.</P>
                    <P>The certain types of benefits outlined above will be in proportion to the extent to which the rule reduces prejudicial, discriminatory, retaliatory, and deceptive practices. The USDA policy has long held that several of the provisions in §§ 201.304 and 201.306 or similar provisions were violations of the Act, although the position has not been established in regulations. Consequently, AMS expects packers, live poultry dealers, and swine contractors to make changes to relatively few contracts.</P>
                    <P>The direct costs of the rule are low because the discriminatory, retaliatory, and deceptive behavior which the rule seeks to mitigate are not overtly written into the terms of the contracts between regulated entities and producers. They are behaviors or conduct in which some regulated entities engage, for example by not offering contracts to some producers due to discrimination and retaliation or by offering less favorable contract terms due to discrimination, retaliation, and deception. If the rule results in less discriminatory, retaliatory, or deceptive behavior by regulated entities, the costs of offering a contract to a producer or grower that was previously denied a contract or amending the terms of a less favorable contract to an impacted producer or grower will be of uncertain. Given that the behavior that the rule seeks to mitigate is not overtly written into contracts and is behavior during the contract offering process, the potential costs of mitigating the behavior are uncertain. The more that discriminatory, retaliatory, and deceptive behavior is mitigated because of the rule, the greater the benefits. AMS does not expect any changes in types of production and marketing contracts offered. AMS expects the same types of contracts to be offered, but with more equitable performance under the contracts by regulated entities across producers, fewer producers denied or terminated from contracts, and better clarity regarding contractual expectations. AMS also expects more contracts to be offered to producers who may not previously have been offered a contract due to discrimination, for example. Given its professional expertise based on regulating the industry and investigating complaints of the prohibited behaviors, AMS does not believe that the discriminatory, retaliatory, and deceptive behavior addressed by this rule is written into contract terms frequently enough to warrant changes to very many contracts.</P>
                    <P>Although the amount of indirect costs is uncertain, AMS expects any indirect costs will likely range from marginal to modest. As shown above, AMS acknowledges that some regulated entities may offer higher prices to some livestock producers and growers when they come into compliance with this rule. This could shift livestock and poultry prices offered to some producers and growers toward the true value of their livestock or poultry that would prevail in a more competitive market and away from the artificially low prices offered through the abuse of market power by engaging in deception, discrimination, or retaliation. This would reduce the cost to society due to the market inefficiency (dead weight loss) created by discriminatory, retaliatory, and deceptive practices by some regulated entities. This shift in prices offered to some producers and growers toward their true value would result, in some instances, in a transfer of excess profits (profits that exceed those that would be earned in a more competitive market) from regulated entities to some growers and producers. This transfer from regulated entities to some producers and growers could occur. AMS cannot quantify the extent to which the behavior this rule aims to prohibit occurs in the industry or the extent of any harm that would be avoided by regulated entities' cessation of the behavior under the clearer limitations set by this rule. AMS notes that regulated entities, in their comments to the proposed rule, asserted that the occurrence of the practices addressed in the rule are not widespread. Assuming this is true, the indirect costs will be marginal. AMS, however, has noted the behaviors have been sufficiently widespread to warrant the intervention provided by this final rule.</P>

                        Packers are currently required to file form PSD 3004, “Annual Report of Packers” OMB control number 0581-0308, with AMS. Among other things, each packer reports the number of head of cattle or calves, hogs, and lamb, sheep, or goats that it processed. Three hundred sixty-five packers that processed cattle or calves, hogs, or lamb, sheep or goats filed reports or were due to file a report with AMS for their fiscal year 2021. Two hundred sixty-one were beef or veal packers. One hundred ninety-six were pork packers, and 139 were lamb, sheep, or goat packers.

                         The number of beef, pork, and lamb packers do not sum to 365 because many firms slaughtered more than one species of livestock. For instance, 112 packers slaughtered both beef and pork, and 66 slaughtered beef, pork, and lamb.

That is, AMS expects that each packer will require one hour of attorney's time and one hour of management time regardless of how many species of livestock it processes. To allocate costs across (1) beef, (2) pork, and (3) lamb processors, AMS allocated one-third of the costs to each of (1) beef, (2) pork, and (3) lamb for packers that processed all three species.

                    <P>Costs to comply with the recordkeeping requirements are likely relatively low. Section 201.304(c) requires specific records that, if the regulated entity maintains, should be kept for a period of five years, including policies and procedures, staff training materials, materials informing covered producers regarding reporting mechanisms and protections, compliance testing, board of directors' oversight materials, and any records of the number and nature of unduly prejudicial or unjustly discriminatory-based complaints received.</P>
                    <P>Costs of recordkeeping include regulated entities maintaining and updating compliance records and are considered a direct cost. Some smaller regulated entities that currently don't maintain records may voluntarily decide to develop formal policies, procedures, training, etc. to comply with the rule and will then have records to maintain.</P>
                    <P>AMS expects the recordkeeping costs will comprise the time required by regulated entities to store and maintain records they already keep. AMS expects that the costs will be relatively small because many packers, live poultry dealers, and swine contractors may currently have few records concerning policies and procedures, staff training materials, materials informing covered producers regarding reporting mechanisms and protections, compliance testing, and board of directors' oversight materials related to prejudicial treatment. Some smaller firms might not have any records to store. Others already store the records and may have no new costs.</P>
                    <P>AMS estimated that recordkeeping time for larger entities will be greater than for smaller entities, and thus estimated costs by quartiles, from largest entities to smallest. AMS estimated that § 201.304(c) will require packers, live poultry dealers, and swine contractors in each quartile an average 4.00 hours, 2.00 hours, 1.33 hours, and 0.67 hours of administrative time for the first, second, third, and fourth quartiles, respectively. Additionally, AMS estimated that the hours required of managers, attorneys, and information technology staff each will average 1.50 hours, 0.75 hours, 0.50 hours, and 0.25 hours for the first, second, third, and fourth quartiles, respectively.</P>
                    <P>AMS also expects that packers, live poultry dealers, and swine contractors will incur continuing recordkeeping costs in each successive year. AMS estimated that § 201.304(c) will require an average of 3.00 hours, 1.50 hours, 1.00 hour, and 0.50 hour of administrative assistant time; 1.50 hours, 0.75 hour, 0.50 hour, and 0.25 hour of time each from managers and attorneys; and 1.00 hour, 0.50 hour, 0.33 hour, and 0.17 hour of time from information technology staff for packers, live poultry dealers, and swine contractors in the first, second, third, and fourth quartiles, respectively, to setup and maintain the required records in each succeeding year.</P>

                        To account for the time value of money, the administrative costs to be incurred in the future are discounted back to today's dollars using a discount rate. The sum of all costs discounted back to the present is called the present value (PV) of total costs. AMS relied on both a three percent and seven percent discount rate as discussed in Circular A-4.

                        The expected costs of this rule are very small relative to the size of the industry; and expected benefits are expected to be proportional to reductions in conduct this rule addresses. Combined sales of beef, pork, and broiler chicken in the U.S. for 2022 were approximately $294.5 billion.
                        <SU>299</SU>
                        <FTREF/>
                         As discussed above, the total cost of §§ 201.304 and 201.306 in the first year is estimated to be $586,000, or 0.0002 percent of revenues. A reduction in prejudicial, discriminatory, retaliatory, and deceptive practices will lead to benefits that will be directly related to the reductions in these practices. If the reductions are small, the benefits will be small. The greater the reductions, the greater the benefits. AMS expects that the costs and benefits to society from the rule will be very small in relation to the total value of industry production, leading to negligible indirect effects on industry supply and demand, including price and quantity effects.

                        The third regulatory alternative that AMS considered is issuing §§ 201.304 and 201.306, but exempting small businesses, as defined by the SBA, from compliance with the recordkeeping requirement of § 201.304(c).

Of the 365 packers reporting to AMS, 348 are small businesses. Two hundred fifty-three beef packers and 183 pork packers are small businesses. All 139 lamb packers are small businesses. Packers include multi-species packers. One hundred eight swine contractors are small businesses. There are 55 small poultry dealers.

                        Table 13 summarizes combined expected administrative and recordkeeping costs for regulated entities in the first year and in succeeding years. AMS expects that administrative and recordkeeping costs associated with a small business exemption alternative will cost each live poultry dealer, swine contractor, and packer an average of $448, $548, and $265, respectively, in the first year. AMS expects costs to average $185, $271, and $27 for live poultry dealers, swine contractors, and packers, respectively, in each succeeding year. First-year costs will total $40,000 for live poultry dealers, $315,000 for swine contractors, and $97,000 for packers. 
                        <PRTPAGE P="16189"/>
                        Costs in successive years will be due to recordkeeping requirements and will total $17,000 for live poultry dealers, $156,000 for swine contractors, and $10,000 for packers annually. The total direct administrative and recordkeeping costs are estimated to be $452,000 in the first year.

                    <P>As discussed above, AMS considers the total costs from §§ 201.304 and 201.306 to be increased direct administrative and recordkeeping costs with no indirect costs from adjustments by the cattle, hog, and poultry industries to reduce their use of AMAs, change to pricing mechanisms or poultry tournaments, and no substantial changes to existing marketing, or growing or production contracts. AMS estimated the costs to small business from the direct administrative costs of §§ 201.304 and 201.306 but excluded the recordkeeping costs of § 201.304(c) in this alternative option.</P>
                    <P>AMS estimated the costs to small business to be the value of the time for management, attorneys, administrative staff, and information technology staff to review the rule and the firms' practices determining compliance with the direct administrative costs of §§ 201.304 and 201.306. AMS estimated costs for the Small Business Exemption Alternative similarly to the final rule. The only difference is the recordkeeping costs of § 201.304(c) attributable to small business are not included in the costs for the Small Business Exemption Alternative. The estimates appear in Table 14. Costs for the final rule are also shown for convenience.</P>

AMS expects the ten-year total costs of § 201.304 and 201.306 with a small business exemption to be $2.1 million.

                    <P>AMS maintains data on live poultry dealers from the annual reports these firms file with AMS. Currently, 90 live poultry dealers will be subject to the regulation. Fifty-five of the live poultry dealers will be small businesses according to the SBA standard.</P>
                    <P>AMS records identified 365 packers that file annual reports or are due to file with PSD for their 2021 fiscal year. Two hundred sixty-one were beef packers. One hundred ninety-six were pork packers, and 139 were lamb or goat packers. Many firms slaughtered more than one species of livestock. For instance, 112 packers slaughtered both beef and pork.</P>
                    <P>Most packers will be small businesses, although large packers are responsible for most meat production. Three hundred forty-eight packers will be small businesses. Two hundred fifty-three beef packers and 183 pork packers were small businesses. All 139 lamb and goat packers were small businesses.</P>
                    <P>AMS does not have similar records for swine contractors because they are not required to register with AMS or provide annual reports. Table 24 of the 2017 USDA Census of Agriculture indicated that there were 575 swine contractors in 2017. The Census of Agriculture table has categories for the number of head that swine contractors sold, but not the value of the head sold. AMS expects that the 467 swine contractors that sold 5,000 head of hogs or more were large businesses, and the 108 contractors that sold less than 5,000 head were small businesses.</P>
                    <P>AMS estimated the costs in two parts. First, AMS expects that each packer, swine contractor, and live poultry dealer will review and learn the new rule and, if necessary, revise production and marketing contracts to ensure compliance with the new rule. Second, AMS expects that packers, live poultry dealers, and swine contractors will have additional costs associated with the new recordkeeping requirements in § 201.304(c).</P>
                    <P>
                        AMS estimated that costs for reviewing and learning the final rule to small live poultry dealers, small packers, and small swine contractors will consist of one hour of a manager's time and one hour of a lawyer's time to review the requirements of §§ 201.304 and 201.306. Expected first-year costs will be $234

                         for each live poultry dealer, each swine contractor, and each packer. This will amount to a total $13,000 for the 55 live poultry dealers, $81,000 for the 348 packers, and $25,000 for the 108 swine contractors.

                        Concerning the recordkeeping requirements in final § 201.304(c), AMS expects the cost will be comprised of the time required to store and maintain records already kept. AMS expects that the costs will be relatively small 
                        <PRTPAGE P="16192"/>
                        because packers, live poultry dealers, and swine contractors will likely have few records concerning policies and procedures, staff training materials, materials informing covered producers regarding reporting mechanisms and protections, compliance testing, and board of directors' oversight materials related to prejudicial treatment. Many firms might not have any records to maintain. Others already maintain the records and have no new costs.
                    </P>
                    <P>AMS expects that recordkeeping costs will be correlated with the size of the firms. AMS ranked packers, live poultry dealers, and swine contractors by size and grouped them into quartiles, estimating more recordkeeping time for larger entities than for the smaller entities. AMS estimated that § 201.304(c) will require an average of 4.00 hours of administrative assistant time, 1.50 hours of time each from managers, attorneys, and information technology staff for packers, live poultry dealers, and swine contractors in the first quartile, containing the largest entities, to setup and maintain the required records in the first year. AMS expects the packers, live poultry dealers, and swine contractors in the second quartile will require an average of 2.00 hours of administrative assistant time, 0.75 hours of time each from managers, attorneys, and information technology staff for first year costs. The third quartile will require 1.33 hours of administrative assistant time, 0.50 hours of time each from managers, attorneys, and information technology staff for first year costs, and the fourth quartile, containing the smallest entities, will require 0.67 hours of administrative assistant time, 0.25 hours of time each from managers, attorneys, and information technology staff.</P>
                    <P>AMS also expects that packers, live poultry dealers, and swine contractors will incur continuing costs in each successive year. AMS estimated that § 201.304(c) will require an average of 3.00 hours of administrative assistant time, 1.50 hours of time each from managers and attorneys, and 1.00 hour of time from information technology staff for packers, live poultry dealers, and swine contractors in the first quartile to setup and maintain the required records in each succeeding year. AMS expects the packers, live poultry dealers, and swine contractors in the second quartile will require an average of 1.50 hours of administrative assistant time, 0.75 hours of time each from managers and attorneys, and 0.50 hours of time from information technology staff in each succeeding year. The third quartile will require 1.00 hour of administrative assistant time, 0.50 hours of time each from managers and attorneys, and 0.33 hours of time from information technology staff in each succeeding year, and the fourth quartile will require 0.50 hours of administrative assistant time, 0.25 hours of time each from managers and attorneys, and 0.17 hours from information technology staff.</P>

                    <P>Live poultry dealers annually file reports with AMS that list each firm's net sales. Packers that purchase more than $500,000 annually in livestock also file annual reports that list net sales. While packers that annually slaughter less than $500,000 in livestock also file annual reports with AMS, in order to reduce the reporting requirements for small packers, they are not required to provide annual net sales.</P>
                    <P>Data from the annual reports enables AMS to compare average net sales for small pork packers, beef packers, and live poultry dealers to the expected costs of §§ 201.304 and 201.306 in the table below. A shortcoming in the comparison is that net sales for smallest packers, those that purchase less than $500,000 in livestock, are not included in the average.</P>
                    <P>Swine contractors are not required to file annual reports with AMS, and similar net sales data are not available for swine contractors. Census of Agriculture's data have the number of head sold by size classes for farms that sold their own hogs and pigs in 2017 and that identified themselves as contractors or integrators, but not the value of sales nor the number of head sold from the farms of the contracted production. To estimate average revenue per establishment, AMS used the estimated average value per head for sales of all swine operations and the production values for firms in the Agriculture Census size classes for swine contractors.</P>
                    <P>Table 19 compares the average per entity first-year costs of final §§ 201.304 and 201.306 to the average revenue per establishment for all regulated small businesses. First-year costs are appropriate for a threshold analysis because all the costs will occur in the first year. First-year costs per regulated entity are considerably higher than annualized costs, and any ratio of annualized costs to revenues will be less than a ratio of first-year costs to revenues.</P>

                    <P>Average first-year costs as a percent of revenues are small. It is highest for swine contractors because average revenues for swine contractors are considerably smaller than average revenues for packers and live poultry dealers. At 0.0711 percent, the average first-year cost is small compared to revenue.</P>
                    <P>Average net sales for packers listed in Table 18 have the problem of excluding the smallest packers, and consequently the averages are biased toward being too large. However, first-year cost as a percent of net sales is 0.0007 percent. Estimated first year cost for each packer is $552. These are relatively small numbers. If average net sales for each packer were only one hundredth of the amount listed in Table 19, estimated average first-year costs will be less than 0.1 percent of net sales.</P>
                    <P>AMS has limited data on revenues for the smallest packers and live poultry dealers. One hundred eleven packers submitted shortened annual reports to AMS because they purchased less than $500,000 in livestock. For the largest of these small packers, annual revenues are likely close to $500,000 and expected costs will be about 0.07 percent.</P>

                    <P>AMS also considered a Small Business Exemption Alternative to final §§ 201.304 and 201.306. The Small Business Exemption Alternative will be the same as the final §§ 201.304 and 201.306 in all respects with the exception that none of the recordkeeping requirements in § 201.304(c) will apply to small businesses. This Small Business Exemption Alternative will cost small packers, swine contractors, and live poultry dealers less than §§ 201.304 and 201.306 will cost. Recordkeeping costs comprised the largest share of the costs associated with §§ 201.304 and 201.306.</P>

AMS expects that small live poultry dealers, small packers, and small swine contractors will need to review the new rule and determine whether the rule will require any changes to their procurement contracts or other business practices and make the necessary changes. AMS estimated that costs will consist of one hour of a manager's time and one hour of a lawyer's time to review the requirements of final §§ 201.304 and 201.306.

                    <P>With either the Small Business Exemption Alternative or the final rule, AMS expects the costs per entity to be relatively small. The number of regulated entities that could experience a cost increase is substantial. Most regulated packers and live poultry dealers are small businesses. However, AMS expects that few small businesses will experience significant costs. For all three groups of regulated entities: packers, live poultry dealers, and swine contractors, average first year costs are expected to amount to less than 0.1 percent of annual revenue for either of the alternatives. AMS expects that any additional costs to small packers, live poultry dealers, and swine contractors from this rulemaking will not change their ability to continue operations or place any small businesses at a competitive disadvantage.</P>
                    <P>AMS chose final §§ 201.304 and 201.306 over the Small Business Exemption Alternative because AMS wishes to prevent the kind of undue prejudices and unjust discrimination described in the rule.

                         A commenter stated that the proposed rule's provisions targeting unjust discrimination could inadvertently ban practices designed to enable Tribal enterprises to serve their own community, such as laws requiring businesses to provide contracting and employment preferences to Tribal members. According to the commenter, these practices could arguably be interpreted under the proposed rule as “offering contract terms that are less favorable than those generally or ordinarily offered” or “differential contract performance or enforcement” which are “based upon the covered producer's status as a market vulnerable individual.” According to the commenter, the regulation's language, as proposed, and the lack of exceptions provided could have a chilling effect on the traditional animal husbandry practices of Tribes regardless of a Tribal business's likelihood of prevailing under a legal challenge.

                         In its final rule, AMS has included a limited list of legitimate business justifications including an exception to the rule's prohibition on unjust discrimination for Tribes fulfilling their governmental function of serving their members. In doing so, AMS in this rule recognizes longstanding practice around Tribal entities, acting in their governmental capacities, in preferencing their own Tribal members and their descendants in the purchase and sale of livestock. Additionally, AMS has changed its approach from the proposed rule to no longer use the term “Market Vulnerable” to define to whom the rule offers protections. In shifting to the specific terms identified, the final rule provides greater certainty that Tribal members will be protected against discriminatory practices they may encounter in the marketplace.

                         A Tribal commenter stated that Tribal producers may be hesitant to report discriminatory practices, stating that the long history of governmental indifference to, or even complicity in, unjust discrimination against their communities' factors into a fear of retaliation. The commenter noted Tribal producers have also reported that they are not sure where to report violations of the Act, suggesting USDA should consider establishing a streamlined process for reporting issues under the Act and make concerted efforts to inform producers of their rights.

                         Through expressly prohibiting discriminatory and retaliatory conduct in this rulemaking, AMS aims to address the commenters concern that “a long history of governmental indifference to, or even complicity in, discrimination against their communities' factors into a fear of retaliation.” AMS has an online portal designed to receive complaints that may amount to violations under the Act and will direct Tribal producers to this portal as well as educating them as to other methods of reporting potential violations. Furthermore, AMS will consult with the USDA Office of Tribal Relations (OTR) and recommend educational outreach to ensure Tribal producers understand how to report a violation.

                         All three commenters urged AMS not to apply the proposed rule to Tribes and Tribal entities. The commenters said Tribes are sovereign governments that retain authority to make their own laws and be ruled by them, unless expressly abrogated. Commenters cited the Supreme Court's holding in

                         that statutory use of the term “person” does not include sovereign entities unless there is an “affirmative showing of statutory intent to the contrary,” arguing that Tribes do not fall within any of these categories.

                         Commenters said the omission of Tribes from the “person” definition also excludes them from being defined as “packers” under the Act, as it defines packers as “any person engaged in” the packing activities enumerated in the definition.

                         In this final rule, AMS excludes Tribes that are fulfilling their governmental function of serving their members from the rule's prohibition on unjust discrimination. In doing so, AMS recognizes the longstanding practice of Tribal entities, acting in their governmental capacities, in preferencing their own Tribal members and their descendants in the purchase and sale of livestock. AMS believes that these changes are sufficient to address the immediate policy concerns underlying the comments in relation to this final rule and that any further changes would be outside the scope of this rule.

                         Commenters stated that “complying with unnecessary and burdensome federal regulations will hinder our small Tribal agricultural operations that already operate on very thin margins.” Arguing that given the small size of packing operations on Tribal land, they may lack the resources or financial ability to comply with recordkeeping and other regulatory requirements the rule imposes. A commenter stated that “record keeping, and other regulatory obligations are always more burdensome to small businesses that lack the legal and compliance departments of a large corporation, and isolated rural locations often struggle to hire and retain adequate office staff.”

                         The economic costs of preventing undue prejudice, unjust discrimination, retaliation, and deception are minor in comparison to the benefit such protections will ensure for farmers and ranchers, including Tribal members. Many businesses already keep records for business purposes, therefore adding hardly any additional costs associated with compliance with this rule. Furthermore, Tribal commenters state that discrimination and retaliation are commonplace in Indian country and that these harms greatly hinder the success of Tribal producers. This rule aims to address those issues directly. AMS notes that the final rule excludes Tribes fulfilling their governmental function of serving their members from the rule's prohibition on unjust discrimination and that any further changes would be outside the scope of this rule.

                         The overarching objective of this rule is to improve market integrity and inclusive competition, and to decrease the undesirable conduct that is facilitated by concentration in agricultural markets. This rule aims to address three specific types of conduct that harm competition: undue prejudice and unjust discrimination, retaliation, and deception. As explained in the RIA/RFA, any regulatory burdens created from enforcing the Act in this regard will be minimal in comparison to the benefits of protecting producers from this harmful conduct. AMS notes that the final rule excludes Tribes fulfilling their governmental function of serving their members from the rule's prohibition on unjust discrimination and that any further changes would be outside the scope of this rule.

                         AMS is issuing this final rule to revise the regulations that effectuate the Act. AMS is adopting these regulations under the Act's provisions prohibiting undue prejudice, unjust discrimination, and deception to establish clearer, more effective standards to govern the modern marketplace and to better protect, through compliance and enforcement, individually harmed producers. AMS is concerned that the current regulations do not adequately address many unduly prejudicial, unjustly discriminatory, retaliatory, and deceptive practices, which are exacerbated by the environment created through increased horizontal concentration and vertical contracting.

                        <E T="03">Who Is Impacted</E>
                        —The effects of this new regulation will fall on packers, swine contractors and live poultry dealers. AMS will cite regulated entities initiating actions or conduct. AMS believes creating an undue prejudice is a violation of section 202(b) of the Act. This is particularly true for those purchasing livestock on a carcass grade, carcass weight, or carcass grade and weight basis, under marketing agreements and production contracts. Swine contractors obtaining swine under swine production contracts and live poultry dealers acquiring poultry through poultry growing arrangements will also feel the impacts of the new regulation.

                        <E T="03">Beneficiaries</E>
                        —The primary beneficiaries of §§ 201.304 and 201.306 will include farmers, feedlot owners, swine production contract growers, and poultry growers. These producers and growers are those most likely to be harmed by undue prejudices, unjust discrimination, retaliation, and deception resulting from the actions or conduct of firms subject to the Act. Identifying criteria for recognizing what actions or conduct may create undue prejudices, discrimination, retaliation, and deception will help lower the number of instances and severity of the harm done by these types of actions or conduct.

                        —Protected groups will see minimal, if any, direct or indirect costs because of the implementation or enforcement of the new regulations. Although the required analysis indicates a disproportionate impact for Asian, and Native Hawaiians or Other Pacific Islanders, because the new regulations impact all industry participants equally, no individual or group would likely be adversely impacted.
                    </P>
                    <P>AMS has considered the potential civil rights implications of this final rule on members of protected groups to ensure that no person or group will be adversely or disproportionately at risk or discriminated against on the basis of race, color, national origin, gender, religion, age, disability, sexual orientation, marital or family status, or protected genetic information.</P>

                        —Executive Order 13175 requires Federal agencies to consult with American Indian Tribes on a government-to-government basis on policies that have Tribal implications. This includes regulations, legislative comments or proposed legislation, and other policy statements or actions. Consultation is required when such policies have substantial direct effects on one or more Indian Tribes, on the relationship between the Federal Government and Indian Tribes, or the distribution of power and responsibilities between the Federal Government and Indian Tribes.
                    </P>
                    <P>AMS has determined that this final rule does not have substantial direct effects on one or more Tribes that would require consultation. If a Tribe requests consultation, AMS will work with USDA's Office of Tribal Relations to ensure meaningful consultation is provided where changes, additions, and modifications identified herein are not expressly mandated by Congress. AMS will also conduct outreach to ensure that Tribes and Tribal members are aware of the requirements and benefits under this final rule.</P>

                        —This final rule affirms the importance of a clear and direct regulatory framework that prohibits deception, retaliation, undue prejudice, and unjust discrimination, thus protecting producers in the marketplace. The rational decision-making and robust competition so critical to economic success can most effectively occur in a market free of such practices.
                    </P>

Agencies generally must prepare a written statement, including cost benefits analysis, for proposed and final rules with “Federal mandates” that may result in expenditures of $100 million or more (adjusted for inflation) in any 1 year for State, local or Tribal governments, in the aggregate, or to the private sector. UMRA generally requires agencies to consider alternatives and adopt the more cost effective or least burdensome alternative that achieves the objectives of the rule. This rule contains no Federal mandates, as defined in title II of UMRA, for State, local, or Tribal Governments, and it does not contain a mandate for the private sector that would likely result in compliance costs of $100 million or more (adjusted annually for inflation) in at least one year. Therefore, this rule is not subject to the requirements of sections 202 and 205 of UMRA.

                        AMS expects that the direct costs of this final rule will be 0.0002 percent of industry revenues in the first year of the rule, or $586,000. Indirect costs would have to be nearly 300 times

                         the expected direct costs to meet the compliance cost threshold of $170 million or more in a single year ($100 million in 1994 dollars adjusted for inflation as of 2021),

                         which AMS has no basis to expect, given its professional expertise gained by regulating the industry and regularly communicating with regulated entities, growers, and producers. Indeed, to reach that threshold, discrimination, retaliation, and deception would have to occur at a prevalence that would have to touch more than 28 percent of all cattle slaughtered in the United States in 2022 and account for the

                         of the difference in prices between the minimum and average liveweight price paid for cattle at the five regional cattle markets over the last 9 years. Extending that analysis to poultry and hogs would not change the conclusion. If anything, it would be even harder to meet the UMRA threshold because almost universal use of the tournament system in the poultry industry means higher compensation to certain growers is unlikely to increase compensation for growers in aggregate. Each tournament has a fixed total compensation pool, with growers ranked relative to other members of their respective tournament and compensated accordingly.

                            Based on the Environmental Protection Agency's (EPA's) reconsideration of the air quality criteria and the national ambient air quality standards (NAAQS) for particulate matter (PM), the EPA is revising the primary annual PM
                            <E T="52">2.5</E>
                             standard by lowering the level from 12.0 µg/m
                            <SU>3</SU>
                             to 9.0 µg/m
                            <SU>3</SU>
                            . The Agency is retaining the current primary 24-hour PM
                            <E T="52">2.5</E>
                             standard and the primary 24-hour PM
                            <E T="52">10</E>
                             standard. The Agency also is not changing the secondary 24-hour PM
                            <E T="52">2.5</E>
                             standard, secondary annual PM
                            <E T="52">2.5</E>
                             standard, and secondary 24-hour PM
                            <E T="52">10</E>
                             standard at this time. The EPA is also finalizing revisions to other key aspects related to the PM NAAQS, including revisions to the Air Quality Index (AQI) and monitoring requirements for the PM NAAQS.

                        This document presents the Administrator's final decisions for the reconsideration of the 2020 final decision on the primary (health-based) and secondary (welfare-based) National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM). More specifically, this document summarizes the background and rationale for the Administrator's final decisions to revise the primary annual PM
                        <E T="52">2.5</E>
                         standard by lowering the level from 12.0 µg/m
                        <SU>3</SU>
                         to 9.0 µg/m
                        <SU>3</SU>
                        ; to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard (at a level of 35 µg/m
                        <SU>3</SU>
                        ); to retain the primary 24-hour PM
                        <E T="52">10</E>
                         standard; and, not to change the secondary PM standards at this time. In reaching his final decisions, the Administrator considered the currently available scientific evidence in the 2019 Integrated Science Assessment (2019 ISA) and the Supplement to the 2019 ISA (ISA Supplement), quantitative and policy analyses presented in the 2022 Policy Assessment (2022 PA), advice from the Clean Air Scientific Advisory Committee (CASAC), and public comments on the proposal. The EPA has established primary and secondary standards for PM
                        <E T="52">2.5</E>
                        , which includes particles with diameters generally less than or equal to 2.5 µm, and PM
                        <E T="52">10</E>
                        , which includes particles with diameters generally less than or equal to 10 µm. The standards include two primary PM
                        <E T="52">2.5</E>
                         standards: an annual average standard, averaged over three years, with a level of 12.0 µg/m
                        <SU>3</SU>
                        , and a 24-hour standard with a 98th percentile form, averaged over three years, and a level of 35 µg/m
                        <SU>3</SU>
                        . It also includes a primary PM
                        <E T="52">10</E>
                         standard with a 24-hour averaging time, and a level of 150 µg/m
                        <SU>3</SU>
                        , not to be exceeded more than once per year on average over three years. Secondary PM standards are set equal to the primary standards, except that the level of the secondary annual PM
                        <E T="52">2.5</E>
                         standard is 15.0 µg/m
                        <SU>3</SU>
                        .

                    <P>The most recent of the PM NAAQS was completed in December 2020. In that review, the EPA retained the primary and secondary NAAQS, without revision (85 FR 82684, December 18, 2020). Following publication of the 2020 final action, several parties filed petitions for review and petitions for reconsideration of the EPA's final decision.</P>
                    <P>
                        In June 2021, the Agency announced its decision to reconsider the 2020 PM NAAQS final action.

                        <FTREF/>
                         The EPA decided to reconsider the December 2020 decision because the available scientific evidence and technical information indicated that the current standards may not be adequate to protect public health and welfare, as required by the Clean Air Act. The EPA noted that the 2020 PA concluded that the scientific evidence and information called into question the adequacy of the primary PM
                        <E T="52">2.5</E>
                         standards and supported consideration of revising the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard to below the current level of 12.0 µg/m
                        <SU>3</SU>
                         while retaining the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard (U.S. EPA, 2020b). The EPA also noted that the 2020 PA concluded that the available scientific evidence and information did not call into question the adequacy of the primary PM
                        <E T="52">10</E>

                         standards have been informed by key aspects of the available health effects evidence and conclusions contained in the 2019 ISA and ISA Supplement, quantitative exposure/risk analyses and policy evaluations presented in the 2022 PA, advice from the CASAC

                         The health effects evidence newly available in this reconsideration, in conjunction with the full body of evidence critically evaluated in the 2019 ISA, supports a causal relationship between long- and short-term exposures and mortality and cardiovascular effects, and the evidence supports a likely to be a causal relationship between long-term exposures and respiratory effects, nervous system effects, and cancer. The longstanding evidence base, including animal toxicological studies, controlled human exposure studies, and epidemiologic studies, reaffirms, and in some cases strengthens, the conclusions from past reviews regarding the health effects of PM
                        <E T="52">2.5</E>
                         exposures. Epidemiologic studies available in this reconsideration demonstrate generally positive, and often statistically significant, PM
                        <E T="52">2.5</E>
                         health effect associations. Such studies report associations between estimated PM
                        <E T="52">2.5</E>
                         exposures and non-accidental, cardiovascular, or respiratory mortality; cardiovascular or respiratory hospitalizations or emergency room visits; and other mortality/morbidity outcomes (
                        <E T="03">e.g.,</E>
                         lung cancer mortality or incidence, asthma development). The scientific evidence available in this reconsideration, as evaluated in the 2019 ISA and ISA Supplement, includes 
                        <PRTPAGE P="16204"/>
                        a number of epidemiologic studies that use various methods to characterize exposure to PM
                        <E T="52">2.5</E>
                         (
                        <E T="03">e.g.,</E>
                         ground-based monitors and hybrid modeling approaches) and to evaluate associations between health effects and lower ambient PM
                        <E T="52">2.5</E>
                         concentrations. There are a number of recent epidemiologic studies that use varying study designs that reduce uncertainties related to confounding and exposure measurement error. The results of these analyses provide further support for the robustness of associations between PM
                        <E T="52">2.5</E>
                         exposures and mortality and morbidity. Moreover, the Administrator notes that recent epidemiologic studies strengthen support for health effect associations at lower PM
                        <E T="52">2.5</E>
                         concentrations, with these new studies finding positive and significant associations when assessing exposure in locations and time periods with lower annual mean and 25th percentile concentrations than those evaluated in epidemiologic studies available at the time of previous reviews. Additionally, the experimental evidence (
                        <E T="03">i.e.,</E>
                         animal toxicological and controlled human exposure studies) strengthens the coherence of effects across scientific disciplines and provides additional support for potential biological pathways through which PM
                        <E T="52">2.5</E>
                         exposures could lead to the overt population-level outcomes reported in epidemiologic studies for the health effect categories for which a causal relationship (
                        <E T="03">i.e.,</E>
                         short- and long-term PM

                         exposure and mortality and cardiovascular effects) or likely to be causal relationship (

                         exposures. The primary analyses focus on exposure and risk associated with air quality that might occur in an area under air quality conditions that just meet the current and potential alternative standards. The risk assessment estimates that the current primary PM
                        <E T="52">2.5</E>
                         standards could allow a substantial number of PM

                        -associated premature deaths in the United States, and that public health improvements would be associated with just meeting all of the alternative (more stringent) annual and 24-hour standard levels modeled. Additionally, the results of the risk assessment suggest that for most of the U.S., the annual standard is the controlling standard and that revision to that standard has the most potential to reduce PM

                         standards to provide the requisite degree of protection, the Administrator recognizes that the current annual standard and 24-hour standard, together, are intended to provide public health protection against the full distribution of short- and long-term PM
                        <E T="52">2.5</E>
                         exposures. Further, he recognizes that changes in PM

                         air quality designed to meet either the annual or the 24-hour standard would likely result in changes to both long-term average and short-term peak PM

                    <P>
                        As in 2012, the Administrator concludes that the most effective way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures is to set a generally controlling annual standard, and to provide supplemental protection against the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations by means of a 24-hour standard set at the appropriate level. Based on the current evidence and quantitative information, as well as consideration of CASAC advice and public comments, the Administrator concludes that the current primary annual PM
                        <E T="52">2.5</E>
                         standard is not adequate to protect public health with an adequate margin of safety. The Administrator notes that the CASAC was unanimous in its advice on the 2021 draft PA regarding the need to revise the annual standard. In considering the appropriate level for a revised annual standard, the Administrator concludes that a standard set at a level of 9.0 µg/m
                        <SU>3</SU>
                         reflects his judgment about placing the most weight on the strongest available evidence while appropriately weighing the uncertainties.

                         standard, the Administrator finds the available scientific evidence and quantitative information to be insufficient to call into question the adequacy of the public health protection afforded by the current 24-hour standard. He further notes that a more stringent annual standard set at a level of 9.0 µg/m
                        <SU>3</SU>
                         is expected to reduce both average (annual) concentrations and peak (daily) concentrations. The Administrator also notes that, in their review of the 2021 draft PA, the CASAC did not reach consensus on whether revisions to the primary 24-hour PM

                        , which are particles with a diameter between 10 µm and 2.5 µm. The final decision to retain the current 24-hour PM
                        <E T="52">10</E>
                         standard has been informed by key aspects of the available health effects evidence and conclusions contained in the 2019 ISA, the policy evaluations presented in the 2022 PA, advice from the CASAC and public comments. Specifically, the health effects evidence for PM
                        <E T="52">10-2.5</E>
                         exposures is somewhat strengthened since past reviews, although the strongest evidence still only provides support for a suggestive of, but not sufficient to infer, causal relationship with long- and short-term exposures and mortality and cardiovascular effects, short-term exposures and respiratory effects, and long-term exposures and cancer, nervous system effects, and metabolic effects. In reaching his final decision on the primary PM
                        <E T="52">10</E>
                         standard, the Administrator recognizes that, while the available health effects evidence has expanded, recent studies are subject to the same types of uncertainties that were judged to be important in previous reviews. He also recognizes that, in their review of the 2019 draft PA and the 2021 draft PA, the CASAC generally agreed that it was reasonable to retain the primary 24-hour PM
                        <E T="52">10</E>
                         standard given the available scientific evidence, including retaining PM

                         as the indicator. He concludes that the newly available evidence does not call into question the adequacy of the current primary PM
                        <E T="52">10</E>
                         standard, and retains that standard, without revision.

                         The Administrator's final decision to not change the current secondary standards at this time has been informed by key aspects of the currently available welfare effects evidence as well as the conclusions contained in the 2019 ISA and ISA Supplement; quantitative analyses of visibility impairment; policy evaluations presented in the 2022 PA; advice from the CASAC; and public comments. Specifically, the welfare effects evidence available in this reconsideration is consistent with the evidence available in previous reviews and supports a causal relationship between PM and visibility, climate, and materials effects. With regard to visibility effects, the Administrator notes that he judges that the evidence supports a target level of protection of 27 dv. He further notes that the results of quantitative analyses of visibility impairment suggest that in areas that meet the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard that estimated light extinction in terms of a 3-year visibility metric would be at or well below the target level of protection. With regard to climate and materials effects, while the evidence has expanded since previous reviews, significant limitations and uncertainties remain in the evidence. While the evidence has expanded since previous reviews, the available scientific evidence remains insufficient to allow the Administrator to make a reasoned judgment about what specific standard(s) would be requisite to protect against known or anticipated adverse effects to public welfare from PM's effects on materials damage or climate.-In their review of the 2019 draft PA and the 2021 draft PA, the CASAC did not recommend revising the secondary PM standards. In considering the available evidence and quantitative information, with its inherent uncertainties and limitations, the Administrator judges that it is appropriate not to change the secondary PM standards at this time.

                             Consistent with the 2016 Integrated Review Plan (U.S. EPA, 2016), other welfare effects of PM, such as ecological effects, are being considered in the separate, on-going review of the secondary NAAQS for oxides of nitrogen, oxides of sulfur and PM. Accordingly, the public welfare protection provided by the secondary PM standards against ecological effects such as those related to deposition of nitrogen- and sulfur-containing compounds in vulnerable ecosystems is being considered in that separate review. Thus, the Administrator's conclusion in this reconsideration of the 2020 final decision is focused only and specifically on the adequacy of public welfare protection provided by the secondary PM standards from effects related to visibility, climate, and materials and hereafter “welfare effects” refers to those welfare effects.

                         NAAQS trigger a process under which States (and Tribes, if they choose) make recommendations to the Administrator regarding designations, identifying areas of the country that either meet or do not meet the new or revised PM NAAQS. Those areas that do not meet the revised PM NAAQS will need to develop plans that demonstrate how they will meet the standards. As part of these plans, states have the opportunity to advance environmental justice, in this case for overburdened communities in areas with high PM concentrations above the NAAQS, by using the tools described in the current PM NAAQS implementation guidance (80 FR 58010, 58136, August 25, 2016). The EPA is not making changes to any of the current PM NAAQS implementation programs in this final rulemaking.

                         sub-index of the Air Quality Index (AQI). First, the EPA is continuing to use the approach used in the revisions to the AQI in 2012 (77 FR 38890, June 29, 2012) of setting the lower breakpoints (50, 100 and 150) based on the levels of the primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards. In so doing, the EPA is revising the AQI value of 50 to 9.0 µg/m
                        <SU>3</SU>
                         and is retaining the AQI values of 100 and 150 at 35.4 µg/m
                        <SU>3</SU>
                         and 55.4 µg/m
                        <SU>3</SU>
                        , respectively. Second, the EPA is revising the upper AQI breakpoints (200 and above), and replacing the linear-relationship approach used in 1999 (64 FR 42530, August 4, 1999) to set these breakpoints, with an approach that more fully considers the PM

                         health effects evidence from controlled human exposure and epidemiologic studies that has become available in the last 20 years. The EPA is also revising the AQI values of 200, 300 and 500 to 125.4 µg/m
                        <SU>3</SU>
                        , 225.4 µg/m

                        <SU>3</SU>
                        , respectively. In addition, this final rule revises the daily reporting requirement from 5 days per week to 7 days per week, while also reformatting appendix G and providing clarifications.

These changes include addressing updates in data calculations, approval of reference and equivalent methods, updates in quality assurance statistical calculations to account for lower concentration measurements, updates to support improvements in PM methods, a revision to the PM

                    <P>Two sections of the Clean Air Act (CAA) govern the establishment and revision of the NAAQS. Section 108 (42 U.S.C. 7408) directs the Administrator to identify and list certain air pollutants and then to issue air quality criteria for those pollutants. The Administrator is to list those pollutants “emissions of which, in his judgment, cause or contribute to air pollution which may reasonably be anticipated to endanger public health or welfare”; “the presence of which in the ambient air results from numerous or diverse mobile or stationary sources”; and for which he “plans to issue air quality criteria. . . .” (42 U.S.C. 7408(a)(1)). Air quality criteria are intended to “accurately reflect the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health or welfare which may be expected from the presence of [a] pollutant in the ambient air. . . .” (42 U.S.C. 7408(a)(2)).</P>

                        Section 109 [42 U.S.C. 7409] directs the Administrator to propose and promulgate “primary” and “secondary” NAAQS for pollutants for which air quality criteria are issued [42 U.S.C. 7409(a)]. Section 109(b)(1) defines primary standards as ones “the attainment and maintenance of which in the judgment of the Administrator, based on such criteria and allowing an adequate margin of safety, are requisite to protect the public health.”

                         Under section 109(b)(2), a secondary standard must “specify a level of air quality the attainment and maintenance of which, in the judgment of the Administrator, based on such criteria, is requisite to protect the public welfare from any known or anticipated adverse effects associated with the presence of [the] pollutant in the ambient air.”

                             The legislative history of section 109 indicates that a primary standard is to be set at “the maximum permissible ambient air level . . . which will protect the health of any [sensitive] group of the population,” and that for this purpose “reference should be made to a representative sample of persons comprising the sensitive group rather than to a single person in such a group.” S.

                        In setting primary and secondary standards that are “requisite” to protect public health and welfare, respectively, as provided in section 109(b), the EPA's task is to establish standards that are neither more nor less stringent than necessary. In so doing, the EPA may not consider the costs of implementing the standards. See generally

                        The requirement that primary standards provide an adequate margin of safety was intended to address uncertainties associated with inconclusive scientific and technical information available at the time of standard setting. It was also intended to provide a reasonable degree of protection against hazards that research has not yet identified. See

Both kinds of uncertainties are components of the risk associated with pollution at levels below those at which human health effects can be said to occur with reasonable scientific certainty. Thus, in selecting primary standards that include an adequate margin of safety, the Administrator is seeking not only to prevent pollution levels that have been demonstrated to be harmful but also to prevent lower pollutant levels that may pose an unacceptable risk of harm, even if the risk is not precisely identified as to nature or degree. The CAA does not require the Administrator to establish a primary NAAQS at a zero-risk level or at background concentration levels, see

                        In addressing the requirement for an adequate margin of safety, the EPA considers such factors as the nature and severity of the health effects involved, the size of the sensitive population(s), and the kind and degree of uncertainties. The selection of any particular approach to providing an adequate margin of safety is a policy choice left specifically to the Administrator's judgment. See

                    <P>States are primarily responsible for ensuring attainment and maintenance of ambient air quality standards once the EPA has established them. Under section 110, Part C, and Part D, Subparts 1 and 4 of the CAA, and related provisions and regulations, States are to submit, for the EPA's approval, State implementation plans (SIPs) that provide for the attainment and maintenance of the NAAQS for PM through control programs directed to sources of the pollutants involved. The States, in conjunction with the EPA, also administer the prevention of significant deterioration of air quality program that covers these pollutants (see 42 U.S.C. 7470-7479). In addition, Federal programs provide for or result in nationwide reductions in emissions of PM and its precursors under Title II of the Act, 42 U.S.C. 7521-7574, which involves controls for motor vehicles and nonroad engines and equipment; the new source performance standards under section 111 of the Act, 42 U.S.C. 7411; and the national emissions standards for hazardous pollutants under section 112 of the Act, 42 U.S.C. 7412.</P>

                        In April 1994, the EPA announced its plans for the second periodic review of the air quality criteria and NAAQS for PM, and in 1997 the EPA promulgated revisions to the NAAQS (62 FR 38652, July 18, 1997). In the 1997 decision, the EPA determined that the fine and coarse fractions of PM
                        <E T="52">10</E>
                         should be considered separately. This determination was based on evidence that serious health effects were associated with short- and long-term exposures to fine particles in areas that met the existing PM
                        <E T="52">10</E>
                         standards. The EPA added new standards, using PM
                        <E T="52">2.5</E>
                         as the indicator for fine particles (with PM
                        <E T="52">2.5</E>
                         referring to particles with a nominal mean aerodynamic diameter less than or equal to 2.5 µm). The new primary standards were as follows: (1) An annual standard with a level of 15.0 µg/m
                        <SU>3</SU>

                         concentrations at each monitor within an area. Also, the EPA established a new reference method for the measurement of PM
                        <E T="52">2.5</E>
                         in the ambient air and adopted rules for determining attainment of the new standards. To continue to address the health effects of the coarse fraction of PM

Area-wide monitors are those sited at the neighborhood scale or larger, as well as those monitors sited at micro- or middle-scales that are representative of many such locations in the same core-based statistical area (CBSA) (78 FR 3236, January 15, 2013).

                        Following promulgation of the 1997 PM NAAQS, petitions for review were filed by several parties, addressing a broad range of issues. In May 1999, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) upheld the EPA's decision to establish fine particle standards and to regulate coarse particle pollution, but vacated the 1997 PM
                        <E T="52">10</E>
                         standards, concluding that the EPA had not provided a reasonable explanation justifying use of PM
                        <E T="52">10</E>
                         as an indicator for coarse particles.

                         standards, and the pre-existing 1987 PM

                         standards remained in place (65 FR 80776, December 22, 2000). The D.C. Circuit also upheld the EPA's determination not to establish more stringent secondary standards for fine particles to address effects on visibility.

                        The D.C. Circuit also addressed more general issues related to the NAAQS, including issues related to the consideration of costs in setting NAAQS and the EPA's approach to establishing the levels of NAAQS. Regarding the cost issue, the court reaffirmed prior rulings holding that in setting NAAQS the EPA is “not permitted to consider the cost of implementing those standards.”

                         175 F. 3d at 1040-41. Regarding the levels of NAAQS, the court held that the EPA's approach to establishing the level of the standards in 1997 (
                        <E T="03">i.e.,</E>
                         both for PM and for the ozone NAAQS promulgated on the same day) effected “an unconstitutional delegation of legislative authority.”

                         175 F. 3d at 1034-40. Although the court stated that “the factors EPA uses in determining the degree of public health concern associated with different levels of ozone and PM are reasonable,” it remanded the rule to the EPA, stating that when the EPA considers these factors for potential non-threshold pollutants “what EPA lacks is any determinate criterion for drawing lines” to determine where the standards should be set.

                        The D.C. Circuit's holding on the cost and constitutional issues were appealed to the United States Supreme Court. In February 2001, the Supreme Court issued a unanimous decision upholding the EPA's position on both the cost and constitutional issues.

                         531 U.S. 457, 464, 475-76. On the constitutional issue, the Court held that the statutory requirement that NAAQS be “requisite” to protect public health with an adequate margin of safety sufficiently guided the EPA's discretion, affirming the EPA's approach of setting standards that are neither more nor less stringent than necessary.

In a March 2002 decision, the D.C. Circuit rejected all remaining challenges to the standards, holding that the EPA's PM

                        In October 1997, the EPA published its plans for the third periodic review of the air quality criteria and NAAQS for PM (62 FR 55201, October 23, 1997). After the CASAC and public review of several drafts, the EPA's National Center for Environmental Assessment (NCEA) finalized the AQCD in October 2004 (U.S. EPA, 2004a). The EPA's Office of Air Quality Planning and Standards (OAQPS) finalized a Risk Assessment and Staff Paper in December 2005 (Abt Associates, 2005; U.S. EPA, 2005).

                         On December 20, 2005, the EPA announced its proposed decision to revise the NAAQS for PM and solicited public comment on a broad range of options (71 FR 2620, January 17, 2006). On September 21, 2006, the EPA announced its final decisions to revise the primary and secondary NAAQS for PM to provide increased protection of public health and welfare, respectively (71 FR 61144, October 17, 2006). With regard to the primary and secondary standards for fine particles, the EPA revised the level of the 24-hour PM

The then-Administrator judged that the available evidence generally did not suggest a link between long-term exposure to existing ambient levels of coarse particles and health or welfare effects. In addition, a new reference method was added for the measurement of PM

                        In December 2014, the EPA announced the initiation of the current periodic review of the air quality criteria for PM and of the PM
                        <E T="52">2.5</E>
                         and PM

                         NAAQS and issued a call for information (79 FR 71764, December 3, 2014). On February 9 to 11, 2015, the EPA's NCEA and OAQPS held a public workshop to inform the planning for the review of the PM NAAQS (announced in 79 FR 71764, December 3, 2014). Workshop participants, including a wide range of external experts as well as the EPA staff representing a variety of areas of expertise (
                        <E T="03">e.g.,</E>
                         epidemiology, human and animal toxicology, risk/exposure analysis, atmospheric science, visibility impairment, climate effects), were asked to highlight significant new and emerging PM research, and to make recommendations to the Agency regarding the design and scope of the review. This workshop provided for a public discussion of the key science and policy-relevant issues around which the EPA structured the review of the PM NAAQS and of the most meaningful new scientific information that would be available in the review to inform understanding of these issues.
                    </P>
                    <P>The input received at the workshop guided the EPA staff in developing a draft IRP, which was reviewed by the CASAC Particulate Matter Panel and discussed on public teleconferences held in May 2016 (81 FR 13362, March 14, 2016) and August 2016 (81 FR 39043, June 15, 2016). Advice from the CASAC, supplemented by the Particulate Matter Panel, and input from the public were considered in developing the final IRP (U.S. EPA, 2016). The final IRP discusses the approaches to be taken in developing key scientific, technical, and policy documents in the review and the key policy-relevant issues that frame the EPA's consideration of whether the primary and/or secondary NAAQS for PM should be retained or revised.</P>

                        In May 2018, the then-Administrator issued a memorandum announcing the Agency's intention to conduct the review of the PM NAAQS in such a manner as to ensure that any necessary revisions were finalized by December 2020 (Pruitt, 2018). Following this memo, on October 10, 2018, the then-Administrator additionally announced that the role of reviewing the key assessments developed as part of the ongoing review of the PM NAAQS (

                    <P>The EPA released the draft ISA in October 2018 (83 FR 53471, October 23, 2018). The draft ISA was reviewed by the chartered CASAC at a public meeting held in Arlington, VA in December 2018 (83 FR 55529, November 6, 2018) and was discussed on a public teleconference in March 2019 (84 FR 8523, March 8, 2019). The CASAC provided its advice on the draft ISA in a letter to the then-Administrator dated April 11, 2019 (Cox, 2019a). The EPA addressed these comments in the final ISA, which was released in December 2019 (U.S. EPA, 2019a).</P>
                    <P>
                        The EPA released the draft PA in September 2019 (84 FR 47944, September 11, 2019). The draft PA was reviewed by the chartered CASAC and discussed in October 2019 at a public meeting held in Cary, NC. Public comments were received via a separate public teleconference (84 FR 51555, September 30, 2019). A public meeting to discuss the chartered CASAC letter and response to charge questions on the draft PA was held in Cary, NC, in October 2019 (84 FR 51555, September 30, 2019), and the CASAC provided its advice on the draft PA, including its advice on the current primary and secondary PM standards, in a letter to the then-Administrator dated December 16, 2019 (Cox, 2019b). With regard to the primary standards, the CASAC recommended retaining the current 24-hour PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards but did not reach consensus on the adequacy of the current annual PM
                        <E T="52">2.5</E>
                         standard. Some CASAC members expressed support for retaining the current primary annual PM
                        <E T="52">2.5</E>
                         standard while other members expressed support for revising that standard in order to increase public health protection (Cox, 2019b, p. 1 of letter). These views are described in greater detail in the letter to the then-Administrator (Cox, 2019b) and in the notice of final rulemaking (85 FR 82706-82707, December 18, 2020), as well as below. With regard to the secondary standards, the CASAC recommended retaining the current standards. In response to the CASAC's comments, the 2020 final PA incorporated a number of changes (Cox, 2019b, U.S. EPA, 2020b), as described in detail in section I.C.5 of the 2020 proposal document (85 FR 24100, April 30, 2020).

                    <P>
                        On April 14, 2020, the EPA proposed to retain all of the primary and secondary PM standards, without revision. These proposed decisions were published in the 
                        <E T="04">Federal Register</E>
                         on April 30, 2020 (85 FR 24094, April 30, 2020). The EPA's final decision on the PM NAAQS was published in the 
                        <E T="04">Federal Register</E>
                         on December 18, 2020 (85 FR 82684, December 18, 2020). In the 2020 rulemaking, the EPA retained the primary and secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards, without revision. The then-Administrator's rationale for his decisions is described in more detail in section II, III, and V below, and is briefly summarized here.
                    </P>
                    <P>
                        In reaching his final decision to retain the primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards, the then-Administrator considered the available scientific evidence, quantitative information, CASAC advice, and public comments in his supporting rationale in the 2020 final action (85 FR 82714, December 18, 2020). In so doing, he concluded that the available controlled human exposure studies did not provide support for additional public health protection against exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations, beyond the protection provided by the combination of the current primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards. He also noted that the available epidemiologic studies did not indicate that associations in those studies are strongly influenced by exposures to peak concentrations in the air quality distribution and thus did not indicate the need for additional protection against short-term exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations. Accordingly, and taking into account consensus CASAC advice to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the then-Administrator concluded the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard should be retained.

                        With respect to the annual PM
                        <E T="52">2.5</E>
                         standard, the then-Administrator recognized that important uncertainties and limitations that were present in epidemiologic studies in previous 
                        <PRTPAGE P="16210"/>
                        reviews remained in the evidence assessed in the 2019 ISA. In considering the epidemiologic evidence, the then-Administrator noted that: (1) The reported mean concentration in the majority of the key U.S. epidemiologic studies using ground-based monitoring data are above the level of the current annual standard; (2) the mean of the reported study means (or medians) (
                        <E T="03">i.e.,</E>
                         13.5 µg/m
                        <SU>3</SU>
                        ) is above the level of the current primary annual PM
                        <E T="52">2.5</E>
                         standard of 12 µg/m
                        <SU>3</SU>
                        ; (3) air quality analyses show the study means to be lower than their corresponding design by 10-20%; and (4) that these analyses must be considered in light of uncertainties inherent in the epidemiologic evidence. The then-Administrator further considered other available information, including the risk assessment, accountability studies, and controlled human exposure studies, and found that, in considering all of the evidence together along with advice from the CASAC, the suite of primary PM
                        <E T="52">2.5</E>
                         standards were requisite to protect public health with an adequate margin of safety, and should be retained, without revision.

                    <P>
                        With regard to the primary PM
                        <E T="52">10</E>
                         standard, the then-Administrator noted that the expanded body of evidence has broadened the range of effects that have been linked with PM
                        <E T="52">10-2.5</E>
                         exposures. In light of that information, as well as continued uncertainties in the evidence and advice from the CASAC to retain the standard, the then-Administrator judged it appropriate to retain the primary PM
                        <E T="52">10</E>
                         standard to provide the requisite degree of public health protection against PM
                        <E T="52">10-2.5</E>
                         exposures, regardless of location, source of origin, or particle composition (85 FR 82725, December 18, 2020).
                    </P>
                    <P>
                        With regard to the secondary PM standards, the then-Administrator concluded that there was insufficient information available to establish any distinct secondary PM standards to address climate and materials effects of PM. For visibility effects, he found that in the absence of a monitoring network for direct measurement of light extinction, a calculated light extinction indicator that utilizes the IMPROVE algorithms continued to provide a reasonable basis for defining a target level of protection against PM-related visibility impairment. He further found that a visibility index with a 24-hour averaging time was reasonable based on its stability and suitability for representing subdaily periods, and a form based on the 3-year average of annual 90th percentile values was reasonable based on its stability and that it represents the median of the 20 percent worst visibility days which are targeted under the Regional Haze program. With regard to the level of a visibility index, the then-Administrator judged it appropriate to establish a target level of protection of 30 dv, reflecting the upper end of the range of visibility impairment judged to be acceptable by at least 50% of study participants in the available public preference studies, taking into consideration the variability, limitations and uncertainties of the public preference studies. The then-Administrator judged that the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard with its level of 35 µg/m
                        <SU>3</SU>
                         would provide at least the target level of protection for visual air quality of 30 dv which he judged appropriate. Accordingly, taking into consideration the advice of the CASAC to retain the current secondary PM standards, the then-Administrator found the current secondary standards provide the requisite degree of protection and that they should be retained (85 FR 82742, December 18, 2020).

                        On June 10, 2021, the Agency announced its decision to reconsider the 2020 PM NAAQS final action because the available scientific evidence and technical information indicate that the current standards may not be adequate to protect public health and welfare, as required by the Clean Air Act.

                         The Administrator reached this decision in part based on the fact that the EPA noted that the 2020 PA concluded that the scientific evidence and information called into question the adequacy of the primary annual PM

                    <P>The EPA staff conclusions detailed in the 2020 PA in combination with the CASAC advice that informed the Administrator's decisions regarding the 2020 final action, studies highlighted by public comments on the 2020 proposal, and the numerous studies published since the literature cutoff date of the 2019 ISA all informed the scope of the reconsideration.</P>
                    <P>
                        In its review of the 2019 draft PA, some members of the CASAC had recommended that greater attention should be given to accountability studies and epidemiologic studies that employ alternative methods for confounder control (also referred to as causal inference or causal modeling studies) in order to “more fully account for effects of confounding, measurement and estimation errors, model uncertainty, and heterogeneity” in epidemiologic studies (Cox, 2019b, p. 8 of consensus responses). In addition, public commenters submitted a number of recent studies published after the literature cutoff date for the 2019 ISA that would have been considered within the scope of the 2019 ISA. While the EPA provisionally considered these studies in responding to public comments,
                        <SU>19</SU>
                        <FTREF/>
                         it was determined that, at the time of the 2020 final action, these studies were generally consistent with the evidence assessed in the 2019 ISA (85 FR 82690, December 18, 2020; U.S. EPA, 2020a). As such, and consistent with previous NAAQS reviews, the EPA concluded that the new studies did not materially change any of the broad scientific conclusions regarding the health and welfare effects of PM in ambient air made in the air quality criteria, and therefore, reopening of the air quality criteria was not warranted (85 FR 82691, December 18, 2020). However, at that time, the EPA 
                        <PRTPAGE P="16211"/>
                        recognized that its “provisional consideration of these studies did not and could not provide the kind of in-depth critical review” (85 FR 82690, December 18, 2020) that studies undergo in the development of an ISA.
                    </P>

                             The list of provisionally considered studies is included in Appendix A to the 2020 Response to Comments document (U.S. EPA, 2020a).

                    <P>
                        In preparing to reconsider the 2020 final decision for the PM NAAQS, the Agency revisited the need to reopen the air quality criteria, given the amount of time that had passed since the literature cutoff date of the 2019 ISA (
                        <E T="03">i.e.,</E>
                         approximately January 2018) and the volume of literature that had become available, including those studies provisionally considered in responding to comments in 2020. In so doing, the EPA preliminarily concluded that at least some of these studies were likely to be relevant to its reconsideration of the air quality criteria and the PM NAAQS and that, in considering public comments on any proposed decisions for the reconsideration, these studies were likely to be raised by public commenters and would potentially warrant a reopening of the air quality criteria. For example, on February 16, 2021, the EPA received two petitions to reconsider the PM NAAQS. One petition objected to the EPA's provisional consideration of studies submitted in public comments on the 2020 proposal and suggested that the provisional consideration was inadequate because the studies could be important in determining whether the existing standards are adequately protective. See, Petition for Reconsideration of National Ambient Air Quality Standards for Particulate Matter, submitted by American Lung Association, et al, dated Feb. 16, 2020. The other petition identified a number of new studies, including one epidemiologic study that was published after the provisional consideration was completed that could further inform the concern expressed by the CASAC that associations reported in epidemiologic studies do not adequately account for “uncontrolled confounding and other potential sources of error and bias.” See Petition for Reconsideration of “Review of the National Ambient Air Quality Standards for Particulate Matter,” submitted by the State of California, dated Feb. 16, 2020. This was also an uncertainty noted by the then-Administrator in the 2020 decision, who also recognized “that methodological study designs to address confounding, such as causal inference methods, are an emerging field of study.” Thus, the Agency concluded it was appropriate to reconsider not only the standards but also the air quality criteria, in light of public comments during the 2020 PM NAAQS proposal and recent studies published since the cutoff date of the 2019 ISA, as reflected in petitions. In deciding to reopen the air quality criteria, the Agency concluded it was reasonable to focus on studies that were most likely to inform decisions on the appropriate standard, but not to reassess areas which, based on the assessment of available science published since the cutoff date of the 2019 ISA and through 2021, were judged unlikely to have new information that would be useful for the Administrator's decision making. The Agency accordingly announced that, in support of the reconsideration, it would develop a supplement to the 2019 ISA and a revised PA.
                    </P>
                    <P>The EPA also explained that the draft ISA Supplement and draft PA would be reviewed at a public meeting by the CASAC, and the public would have opportunities to comment on these documents during the CASAC review process, as well as to provide input during the rulemaking through the public comment process and public hearings on the proposed rulemaking.</P>

                        On March 31, 2021, the Administrator announced his decision to reestablish the membership of the CASAC to “ensure the agency received the best possible scientific insight to support our work to protect human health and the environment.”

                        The draft ISA Supplement was released in September 2021 (U.S. EPA, 2021a; 86 FR 54186, September 30, 2021), and included a discussion of the rationale and scope of the Supplement. As explained therein, the ISA Supplement focuses on a thorough evaluation of some studies that became available after the literature cutoff date of the 2019 ISA that could either further inform the adequacy of the current PM NAAQS or address key scientific topics that have evolved since the literature cutoff date for the 2019 ISA. In selecting the health effects to evaluate within the ISA Supplement, the EPA focused on health effects for which the evidence supported a “causal relationship” because those were the health effects that were most useful in informing conclusions in the 2020 PA (U.S. EPA, 2022a, section 1.2.1).

                         Consistent with the rationale for the focus on certain health effects, in selecting the non-ecological welfare effects to evaluate within the ISA Supplement, the EPA focused on the non-ecological welfare effects for which the evidence supported a “causal relationship” and for which quantitative analyses could be supported by the evidence because those were the welfare effects that were most useful in informing conclusions in the 2020 PA.

                         Specifically, for non-ecological welfare effects, the focus within the ISA Supplement is on visibility effects. The ISA Supplement also considers recent health effects evidence that addresses key scientific topics where the literature has evolved since the 2020 review was completed,

While the 2020 PA considered the broader set of evidence for these effects, for climate effects and material effects, it concluded that there remained `substantial uncertainties with regard to the quantitative relationships with PM concentrations and concentration patterns that limit[ed] [the] ability to quantitatively assess the public welfare protection provided by the standards from these effects' (U.S. EPA, 2020b).”

                        Given the narrow scope of the ISA Supplement, it is important to recognize that the evaluation does not encompass the full multidisciplinary evaluation presented within the 2019 ISA that would result in weight-of-evidence conclusions on causality (

                        In developing a revised PA to support the reconsideration, the EPA considered the available scientific evidence, including the evidence presented in the 2019 ISA and ISA Supplement. The 2022 PA considered the quantitative and technical information presented in the 2020 PA, in addition to new and updated analyses conducted since the 2020 final decision. For those health and welfare effects for which the ISA Supplement evaluated recently available studies (
                        <E T="03">i.e.,</E>
                         PM

                        -related health effects and visibility effects), new updated quantitative analyses were conducted as a part of the development of the 2022 PA. The newly available scientific and technical information presented in the 2022 PA were considered in reaching conclusions regarding the adequacy of the current standards and any potential alternative standards. For those health and welfare effects for which newly available scientific and technical information were not evaluated (
                        <E T="03">i.e.,</E>

                    <P>The chartered CASAC provided its advice on the draft ISA Supplement in a letter to the EPA Administrator dated March 18, 2022 (Sheppard, 2022b). In its review of the draft ISA Supplement, the CASAC noted that they found “the Draft ISA Supplement to be a well-written, comprehensive evaluation of the new scientific information published since the 2019 PM ISA” (Sheppard, 2022b, p. 2 of letter). Furthermore, the CASAC stated that “the final Integrated Science Assessment (ISA) Supplement . . . deserve[s] the Administrator's full consideration and [is] adequate for rulemaking” (Sheppard, 2022b, p. 2 of letter). The CASAC generally endorsed EPA's decisions regarding the limited scope of the draft ISA Supplement, stating that “this limitation [on scope] is appropriate for the targeted purpose of the Draft ISA Supplement” although the CASAC noted it would not be appropriate for ISAs generally, and recommended that the EPA provide additional acknowledgment and explanation for the limited scope (Sheppard, 2022b, p. 2 of letter; see also pp. 2-3 of consensus responses). The EPA specifically noted in the final ISA Supplement, which was released in May 2022 (U.S. EPA, 2022a; hereafter referred to as the ISA Supplement throughout this document) that the “targeted approach to developing the Supplement to the 2019 PM ISA for the purpose of reconsidering the 2020 PM NAAQS decision does not reflect a change to EPA's approach for developing ISAs for NAAQS reviews.” Thus, the evidence presented within the 2019 ISA, along with the targeted identification and evaluation of new scientific information in the ISA Supplement, provides the scientific basis for the reconsideration of the 2020 PM NAAQS final decision.</P>

                        The draft PA was released in October 2021 (86 FR 56263, October 8, 2021). The CASAC PM panel met at a virtual public meeting in December 2021 to review the draft PA (86 FR 52673, September 22, 2021). A virtual public meeting was then held in February 2022 and March 2022, and during this meeting the chartered CASAC considered the CASAC PM panel's draft letter to the Administrator on the draft PA (87 FR 958, January 7, 2022). The chartered CASAC provided its advice on the draft PA in a letter to the EPA Administrator dated March 18, 2022 (Sheppard, 2022a). The EPA took steps to address these comments in revising and finalizing the PA. The 2022 PA considers the scientific evidence presented in the 2019 ISA and ISA Supplement and considers the quantitative and technical information presented in the 2020 PA, along with updated and newly available analyses since the completion of the 2020 review.

                         on January 27, 2023 (88 FR 5558, January 27, 2023). The EPA held a multi-day virtual public hearing on February 21-23, 2023 (88 FR 6215, January 31, 2023). In total, the EPA received nearly 700,000 comments on the proposal from members of the public by the close of the public comment period on March 28, 2023. Major issues raised in the public comments are discussed throughout the preamble of this final action. A more detailed summary of all significant comments, along with the EPA's responses (henceforth “Response to Comments” document), can be found in the docket for this rulemaking (Docket No. EPA-HQ-OAR-2015-0072).

                        As in prior reviews, the EPA is basing its decision in this reconsideration on studies and related information in the air quality criteria, which have undergone CASAC and public review. These studies assessed in the 2019 ISA 
                        <SU>27</SU>
                        <FTREF/>

                        <SU>28</SU>
                        <FTREF/>
                         and the 2022 PA, and the integration of the scientific evidence presented in them, have undergone extensive critical review by the EPA, the CASAC, and the public. Decisions on the NAAQS should be based on studies that have been rigorously assessed in an integrative manner not only by the EPA but also by the statutorily mandated independent scientific advisory committee, as well as the public review that accompanies this process. It is for this reason that the EPA preliminarily concluded that the scientific evidence available since the completion of the 2019 ISA, including those raised in public comments on the proposal in 2020, warranted a partial reopening of the air quality criteria and prepared an ISA Supplement to enable the EPA, the CASAC, and the public to consider them further. Some commenters have referred to and discussed additional individual scientific studies on the health effects of PM that were not included in the 2019 ISA or ISA Supplement (“new studies”) and that have not gone through this comprehensive review process. In considering and responding to comments for which such “new” studies were cited in support, the EPA has provisionally considered the cited studies in the context of the findings of the 2019 ISA and ISA Supplement. The EPA's provisional consideration of these studies did not and could not provide the kind of in-depth critical review described above, but rather was focused on determining whether they warranted further reopening the review of the air quality criteria to enable the EPA, the CASAC, and the public to consider them further.

                             In addition to the 2020 review's opening “call for information” (79 FR 71764, December 3, 2014), the 2019 ISA identified and evaluated studies and reports that have undergone scientific peer review and were published or accepted for publication between January 1, 2009, through approximately January 2018 (U.S. EPA, 2019a, p. ES-2). References that are cited in the 2019 ISA, the references that were considered for inclusion but not cited, and electronic links to bibliographic information and abstracts can be found at:

                             As described above, the ISA Supplement represents an evaluation of recent studies that are of greatest policy relevance and utility to the reconsideration of the 2020 final decision on the PM NAAQS (U.S. EPA, 2022a).

                    <P>This approach, and the decision to rely on the studies and related information in the air quality criteria, which have undergone CASAC and public review, is consistent with the EPA's practice in prior NAAQS reviews and its interpretation of the requirements of the CAA. Since the 1970 amendments, the EPA has taken the view that NAAQS decisions are to be based on scientific studies and related information that have been assessed as a part of the pertinent air quality criteria, and the EPA has consistently followed this approach. This longstanding interpretation was strengthened by new legislative requirements enacted in 1977, which added section 109(d)(2) of the Act concerning CASAC review of air quality criteria. See 71 FR 6114, 61148 (October 17, 2006, final decision on review of NAAQS for particulate matter) for a detailed discussion of this issue and the EPA's past practice.</P>
                    <P>
                        As discussed in the EPA's 1993 decision not to review the O
                        <E T="52">3</E>
                         NAAQS, “new” studies may sometimes be of such significance that it is appropriate to delay a decision in a NAAQS review and to supplement the pertinent air quality criteria so the studies can be taken into account (58 FR 13013-13014, March 9, 1993). In the present case, the EPA decided to partially reopen the air quality criteria and prepared an ISA Supplement as a part of the reconsideration to facilitate evaluation of these studies by the EPA, the CASAC, and the public. The narrow scope of the ISA Supplement is supported by EPA's provisional consideration of “new” studies submitted in response to public comments on the 2020 proposal which concluded that, taken in context, the “new” information and findings do not materially change any of the broad scientific conclusions regarding the health and welfare effects of PM in ambient air made in the air quality criteria. Therefore, a full reopening of the air quality criteria was not warranted to assess the health and welfare effects of PM for purposes of the review.
                    </P>
                    <P>Accordingly, the EPA is basing the final decisions in this reconsideration on the studies and related information included in the PM air quality criteria (including the 2019 PM ISA and ISA Supplement) that have undergone rigorous review by the EPA, the CASAC, and the public. The EPA will consider these “new” studies for inclusion in the air quality criteria for the next PM NAAQS review, which the EPA expects to begin soon after the conclusion of this reconsideration and which will provide the opportunity to fully assess these studies through a more rigorous review process involving the EPA, the CASAC, and the public.</P>

                        In ambient air, PM is a mixture of substances suspended as small liquid and/or solid particles (U.S. EPA, 2019a, section 2.2) and distinct health and welfare effects have been linked with exposures to particles of different sizes. Particles in the atmosphere range in size from less than 0.01 to more than 10 μm

                        in diameter (U.S. EPA, 2019a, section 2.2). The EPA defines PM

                        , also referred to as fine particles, as particles with aerodynamic diameters generally less than or equal to 2.5 μm. The size range for PM
                        <E T="52">10-2.5</E>
                        , also called coarse or thoracic coarse particles, includes those particles with aerodynamic diameters generally greater than 2.5 μm and less than or equal to 10 μm. PM
                        <E T="52">10</E>
                        , which is comprised of both fine and coarse fractions, includes those particles with aerodynamic diameters generally less than or equal to 10 μm. In addition, ultrafine particles (UFP) are often defined as particles with a diameter of less than 0.1 μm based on physical size, thermal diffusivity or electrical mobility (U.S. EPA, 2019a, section 2.2). Atmospheric lifetimes are generally longest for PM
                        <E T="52">2.5</E>
                        , which often remains in the atmosphere for days to weeks (U.S. EPA, 2019a, Table 2-1) before being removed by wet or dry deposition, while atmospheric lifetimes for UFP and PM
                        <E T="52">10-2.5</E>
                         are shorter and are generally removed from the atmosphere within hours, through wet or dry deposition (U.S. EPA, 2019a, Table 2-1; U.S. EPA, 2022b, section 2.1).

                    <P>
                        PM is composed of both primary (directly emitted particles) and secondary particles. Primary PM is derived from direct particle emissions from specific PM sources while secondary PM originates from gas-phase precursor chemical compounds present in the atmosphere that have participated in new particle formation or condensed onto existing particles (U.S. EPA, 2019a, section 2.3). As discussed further in the 2019 ISA (U.S. EPA, 2019a, section 2.3.2.1), secondary PM is formed in the atmosphere by photochemical oxidation reactions of both inorganic and organic gas-phase precursors. Precursor gases include sulfur dioxide (SO
                        <E T="52">2</E>
                        ), nitrogen oxides (NO
                        <E T="52">X</E>
                        ), and volatile organic compounds (VOC) (U.S. EPA, 2019a, section 2.3.2.1). Ammonia also plays an important role in the formation of nitrate PM by neutralizing sulfuric acid and nitric acid. Sources and emissions of PM are discussed in more detail the 2022 PA (U.S. EPA, 2022b, section 2.1.1). Briefly, anthropogenic sources of PM include both stationary (
                        <E T="03">e.g.,</E>
                         fuel combustion for electricity production and other purposes, industrial processes, agricultural activities) and mobile (

                         diesel- and gasoline-powered highway vehicles and other engine-driven sources) sources. Natural sources of PM include dust from the wind erosion of natural surfaces, sea salt, wildfires, primary biological aerosol particles (PBAP) such as bacteria and pollen, oxidation of biogenic hydrocarbons, such as isoprene and terpenes to produce secondary organic aerosol (SOA), and geogenic sources, such as sulfate formed from volcanic production of SO
                        <E T="52">2</E>
                        . Wildland fire, which encompass both wildfire and prescribed fire, accounts for 44% of emissions of primary PM
                        <E T="52">2.5</E>
                         emissions (U.S. EPA, 2021b). Emissions from wildfire comprises 29% of primary PM
                        <E T="52">2.5</E>
                         emissions.

                        In recent years, the frequency and magnitude of wildfires have increased (U.S. EPA, 2019a). The magnitude of the public health impact of wildfires is substantial both because of the increase in PM
                        <E T="52">2.5</E>
                         concentrations as well as the duration of the wildfire smoke season, which is considered to range from May to November. Wildfire can make a large contribution to air pollution (including PM
                        <E T="52">2.5</E>
                        ), and wildfire events can threaten public safety and life. The impacts of wildfire events can be mitigated through management of wildland vegetation, including through prescribed fire. Prescribed fire (and some wildfires) can mimic the natural processes necessary to maintain fire-dependent ecosystems, minimizing catastrophic wildfires and the risks they pose to safety, property and air quality (see, 
                        <E T="03">e.g.,</E>
                         81 FR 58010, 58038, August 24, 2016). The EPA views the strategic use of prescribed fire as an important tool for reducing wildfire risk and the severity of wildfires and wildfire smoke (88 FR, 54118, 54126, August 9, 2023).

                        Wildfire events produce high PM emissions that may impact the PM concentrations in ambient air to the extent that the concentrations result in an exceedance or violation which may affect the design value in a given area. The EPA's Exceptional Events Rule (81 FR 68216, October 3, 2016) describes the process by which air agencies may request to exclude `event-influenced' data caused by exceptional events, which can include wildfires and prescribed fires on wildland. The EPA has issued guidance specifically addressing exceptional events demonstrations for both wildfires and prescribed fires on wildland. These documents are available on EPA's Exceptional Events Program website.

                        To promote uniform application of the air quality standards set forth under the CAA and to achieve the degree of public health and welfare protection intended for the NAAQS, the EPA establishes PM Federal Reference Methods (FRMs) for both PM

                         in appendices J and L to 40 CFR part 50, both of which were amended following the 2006 and 2012 PM NAAQS reviews. The current PM monitoring network relies on FRMs and automated continuous Federal Equivalent Methods (FEMs) approved pursuant to 40 CFR part 53, in part to support changes necessary for implementation of the revised PM standards. Additionally, 40 CFR part 58, appendices A through E, detail the requirements to measure ambient air quality and report ambient air quality data and related information. More information on PM ambient monitoring networks is available in section 2.2 of the 2022 PA (U.S. EPA, 2022b).

Urban particle number counts were several times higher than at the background site, and the highest particle number counts in an urban area with multiple sites (Buffalo) were observed at a near-road location (U.S. EPA, 2022b, section 2.3.2.6).

                    <P>
                        In this reconsideration, background PM is defined as all particles that are formed by sources or processes that cannot be influenced by actions within the jurisdiction of concern. U.S. background PM is defined as any PM formed from emissions other than U.S. anthropogenic (
                        <E T="03">i.e.,</E>
                         manmade) emissions. Potential sources of U.S. background PM include both natural sources (
                        <E T="03">i.e.,</E>
                         PM that would exist in the absence of any anthropogenic emissions of PM or PM precursors) and transboundary sources originating outside U.S. borders. Background PM is discussed in more detail in the 2022 PA (U.S. EPA, 2022b, section 2.4). At annual and national scales, estimated background PM concentrations in the U.S. are small compared to contributions from domestic anthropogenic sources.
                        <SU>44</SU>
                        <FTREF/>
                         For example, based on zero-out modeling in the last review of the PM NAAQS, annual background PM
                        <E T="52">2.5</E>
                         concentrations were estimated to range from 0.5-3 µg/m
                        <SU>3</SU>
                         across the sites examined. In addition, speciated monitoring data from IMPROVE sites can provide some insights into how contributions from different sources, including sources of background PM, may have changed over time. Such data suggests the estimates of background concentrations using speciated monitoring data from IMPROVE monitors are around 1-3 µg/m
                        <SU>3</SU>
                         and have not changed significantly since the 2012 review. Contributions to background PM in the U.S. result mainly from sources within North America. Contributions from intercontinental events have also been documented (
                        <E T="03">e.g.,</E>
                         transport from dust storms occurring in deserts in North Africa and Asia), but these events are less frequent and represent a relatively small fraction of background PM in most of the U.S. (U.S. EPA, 2022b, section 2.4).

                             Sources that contribute to natural background PM include dust from the wind erosion of natural surfaces, sea salt, wildland fires, primary biological aerosol particles such as bacteria and pollen, oxidation of biogenic hydrocarbons such as isoprene and terpenes to produce secondary organic aerosols (SOA), and geogenic sources such as sulfate formed from volcanic production of SO

                             and oceanic production of dimethyl-sulfide (U.S. EPA, 2022b, section 2.4). While most of these sources release or contribute predominantly to fine aerosol, some sources including windblown dust, and sea salt also produce particles in the coarse size range (U.S. EPA, 2019a, section 2.3.3).

Additionally, this rationale is based on a thorough evaluation of some studies that became available after the literature cutoff date of the 2019 ISA, as evaluated in the ISA Supplement, that could either further inform the adequacy of the current PM NAAQS or address key scientific topics that have evolved since the literature cutoff date for the 2019 ISA, generally through March 2021 (U.S. EPA, 2022a).

                        <FTREF/>
                         The Administrator's rationale also takes into account: (1) The 2022 PA evaluation of the policy-relevant information in the 2019 ISA and ISA Supplement and presentation of quantitative analyses of air quality and health risks; (2) CASAC advice and recommendations; and (3) public comments received during the development of these documents.

                             The ISA Supplement represents an evaluation of recent studies that are of greatest policy relevance to the reconsideration of the 2020 final decision on the PM NAAQS. Specifically, the ISA Supplement focuses on studies of health effects for which the evidence in the 2019 ISA supported a “causal relationship” (
                            <E T="03">i.e.,</E>

                             exposure and mortality and cardiovascular effects) because those were the health effects that were most useful in informing conclusions in the 2020 PA. The ISA Supplement does not include an evaluation of studies for other PM

                        In presenting the rationale for the Administrator's decisions and its foundations, section II.A provides background on the general approach for this reconsideration and the basis for the existing standard, and also presents brief summaries of key aspects of the currently available health effects and risk information. Section II.B summarizes the CASAC advice and the basis for the proposed conclusions, addresses public comments received on the proposal and presents the Administrator's conclusions on the adequacy of the current standards, drawing on consideration of the scientific evidence and quantitative risk information, advice from the CASAC, and comments from the public. Section II.C summarizes the Administrator's decision on the primary PM

                        The general approach for this reconsideration of the 2020 final decision on the primary PM
                        <E T="52">2.5</E>
                         standards is fundamentally based on using the EPA's assessment of the current scientific evidence and associated quantitative analyses to inform the Administrator's judgment regarding primary PM
                        <E T="52">2.5</E>
                         standards that protect public health with an adequate margin of safety. The EPA's assessments are primarily documented in the 2019 ISA, ISA Supplement, and 2022 PA, all of which have received CASAC review and public comment (83 FR 53471, October 23, 2018; 83 FR 55529, November 6, 2018; 85 FR 4655, January 27, 2020; 86 FR 52673, September 22, 2021; 86 FR 54186, September 30, 2021; 86 FR 56263, October 8, 2021; 87 FR 958, January 7, 2022; 87 FR 22207, April 14, 2022; 87 FR 31965, May 26, 2022). In bridging the gap between the scientific assessments of the 2019 ISA and ISA Supplement and the judgments required of the Administrator in determining whether the current standards provide the requisite public health protection, the 2022 PA evaluates policy implications of the evaluation of the current evidence in the 2019 ISA and ISA Supplement, and the risk information documented in the 2022 PA. In evaluating the public health protection afforded by the current standards, the four basic elements of the NAAQS (
                        <E T="03">i.e.,</E>
                         indicator, averaging time, level, and form) are considered collectively.

                    <P>
                        The final decision on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards is a public health policy judgment to be made by the Administrator. In reaching conclusions with regard to the standards, the decision will draw on the scientific information and analyses about health effects and population risks, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the scientific evidence and analyses. This approach is based on the recognition that the available health effects evidence generally reflects a continuum, consisting of levels at which scientists generally agree that health effects are likely to occur, through lower levels at which the likelihood and magnitude of the response become increasingly uncertain. This approach is consistent with the requirements of the NAAQS provisions of the Clean Air Act and with how the EPA and the courts have historically interpreted the Act (summarized in section I.A above). These provisions require the Administrator to establish primary standards that, in the judgment of the Administrator, are requisite to protect public health with an adequate margin of safety. In so doing, the Administrator seeks to establish standards that are neither more nor less stringent than necessary for this purpose. The Act does not require that primary standards be set at a zero-risk level, but rather at a level that avoids unacceptable risks to public health, including the health of sensitive (also referred to as “at-risk”) groups.

                         exposures (U.S. EPA, 2019a). Much of the evidence came from epidemiologic studies conducted in North America, Europe, or Asia examining short-term and long-term exposures that demonstrated generally positive, and often statistically significant, PM

                         standards, placing the greatest weight on evidence of effects for which the 2019 ISA determined there to be a causal or likely to be causal relationship with long- and short-term PM
                        <E T="52">2.5</E>

                        <E T="52">2.5</E>
                         exposures. He noted the 2020 PA conclusions that the information continued to support the PM
                        <E T="52">2.5</E>
                         mass-based indicator and remained too limited to support a distinct standard for any specific PM

                         as the indicator for the primary standards for fine particles (85 FR 82715, December 18, 2020).

                        With respect to averaging time and form, the then-Administrator noted that the scientific evidence continued to provide strong support for health effects associations with both long-term (
                        <E T="03">e.g.,</E>
                         annual or multi-year) and short-term (
                        <E T="03">e.g.,</E>
                         mostly 24-hour) exposures to PM
                        <E T="52">2.5</E>
                        , consistent with the conclusions in the 2020 PA. In the 2019 ISA, epidemiologic and controlled human exposure studies examined a variety of PM
                        <E T="52">2.5</E>
                         exposure durations. Epidemiologic studies continued to provide strong support for health effects associated with short-term PM
                        <E T="52">2.5</E>
                         exposures based on 24-hour PM
                        <E T="52">2.5</E>
                         averaging periods, and the EPA noted that associations with subdaily estimates are less consistent and, in some cases, smaller in magnitude (U.S. EPA, 2019a, section 1.5.2.1; U.S. EPA, 2020b, section 3.5.2.2). In addition, controlled human exposure and panel-based studies of subdaily exposures typically examined subclinical effects, rather than the more serious population-level effects that have been reported to be associated with 24-hour exposures (
                        <E T="03">e.g.,</E>
                         mortality, hospitalizations). Taken together, the 2019 ISA concluded that epidemiologic studies did not indicate that subdaily averaging periods were more closely associated with health effects than the 24-hour average exposure metric (U.S. EPA, 2019a, section 1.5.2.1). Additionally, while controlled human exposure studies provided consistent evidence for cardiovascular effects following PM
                        <E T="52">2.5</E>
                         exposures for less than 24 hours (
                        <E T="03">i.e.,</E>
                         &lt;30 minutes to 5 hours), exposure concentrations in the studies were well-above the ambient concentrations typically measured in locations meeting the existing standards (U.S. EPA, 2020b, section 3.2.3.1). Thus, these studies also did not suggest the need for additional protection against subdaily PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2020b, section 3.5.2.2). Therefore, the then-Administrator judged that the 24-hour averaging time remained appropriate (85 FR 82715, December 18, 2020).

                    <P>
                        With regard to the form of the 24-hour standard (98th percentile, averaged over three years), the then-Administrator noted that epidemiologic studies continued to provide strong support for health effect associations with short-term (
                        <E T="03">e.g.,</E>
                         mostly 24-hour) PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2020b, section 3.5.2.3) and that controlled human exposure studies provided evidence for health effects following single short-term “peak” PM
                        <E T="52">2.5</E>
                         exposures. Thus, the evidence supported retaining a standard focused on providing supplemental protection against short-term peak exposures and supported a 98th percentile form for a 24-hour standard. The then-Administrator further noted that this form also provided an appropriate balance between limiting the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations and identifying a stable target for risk management programs (U.S. EPA, 2020b, section 3.5.2.3). As such, the then-Administrator concluded that the available information supported retaining the form and averaging time of the current 24-hour standard (98th percentile, averaged over three years) and annual standard (annual average, averaged over three years) (85 FR 82715, December 18, 2020).

                        With regard to the level of the standards, in reaching his final decision, the then-Administrator considered the large body of evidence presented and assessed in the 2019 ISA (U.S. EPA, 2019a), the policy-relevant and risk-based conclusions and rationales as presented in the 2020 PA (U.S. EPA, 2020b), advice from the CASAC, and public comments. In particular, in considering the 2019 ISA and 2020 PA, he considered key epidemiologic studies that evaluated associations between PM
                        <E T="52">2.5</E>
                         air quality distributions and mortality and morbidity, including key accountability studies; the availability of experimental studies to support biological plausibility; controlled human exposure studies examining effects following short-term PM
                        <E T="52">2.5</E>
                         exposures; air quality analyses; and the important uncertainties and limitations associated with the information (85 FR 82715, December 18, 2020).

                    </P>
                    <P>
                        As an initial matter, the then-Administrator considered the protection afforded by both the annual and 24-hour standards together against long- and short-term PM
                        <E T="52">2.5</E>
                         exposures and health effects. The Administrator recognized that the annual standard was most effective in controlling “typical” PM
                        <E T="52">2.5</E>
                         concentrations near the middle of the air quality distribution (
                        <E T="03">i.e.,</E>
                         around the mean of the distribution), but also provided some control over short-term peak PM
                        <E T="52">2.5</E>
                         concentrations. On the other hand, the 24-hour standard, with its 98th percentile form, was most effective at limiting peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations, but in doing so also had an effect on annual average PM
                        <E T="52">2.5</E>
                         concentrations. Thus, while either standard could be viewed as providing some measure of protection against both average exposures and peak exposures, the 24-hour and annual standards were not expected to be equally effective at limiting both types of exposures. Thus, consistent with previous reviews, the then-Administrator's consideration of the public health protection provided by the existing primary PM
                        <E T="52">2.5</E>
                         standards was based on his consideration of the combination of the annual and 24-hour standards. Specifically, he recognized that the annual standard was more likely to appropriately limit the “typical” daily and annual exposures that are most strongly associated with the health effects observed in epidemiologic studies. The then-Administrator concluded that an annual standard (as the arithmetic mean, averaged over three years) remained appropriate for targeting protection against the annual and daily PM
                        <E T="52">2.5</E>
                         exposures around the middle portion of the PM
                        <E T="52">2.5</E>
                         air quality distribution. Further, recognizing that the 24-hour standard (with its 98th percentile form) was more directly tied to short-term peak PM
                        <E T="52">2.5</E>
                         concentrations, and more likely to appropriately limit exposures to such concentrations, the then-Administrator concluded that the current 24-hour standard (with its 98th percentile form, averaged over three years) remained appropriate to provide a balance between limiting the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations and identifying a stable target for risk management programs. However, the then-Administrator recognized that changes in PM
                        <E T="52">2.5</E>
                         air quality to meet an annual standard would likely result not only in lower short- and long-term PM
                        <E T="52">2.5</E>
                         concentrations near the middle of the air quality distribution, but also in fewer and lower short-term peak PM
                        <E T="52">2.5</E>
                         concentrations. The then-Administrator further recognized that changes in air quality to meet a 24-hour standard, with a 98th percentile form, would result not only in fewer and lower peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations, but also in lower annual average PM
                        <E T="52">2.5</E>
                         concentrations (85 FR 82715-82716, December 18, 2020).

                    <P>
                        Thus, in considering the adequacy of the 24-hour standard, the then-Administrator noted the importance of considering whether additional protection was needed against short-term exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations. In examining the scientific evidence, he noted the limited utility of the animal toxicological studies in directly informing conclusions on the appropriate level of the standard given the uncertainty in extrapolating from effects in animals to those in human populations. The then-Administrator noted that controlled human exposure studies provided evidence for health effects following single, short-term PM
                        <E T="52">2.5</E>
                         exposures that corresponded best to exposures that might be experienced in the upper end of the PM
                        <E T="52">2.5</E>
                         air quality distribution in the U.S. (
                        <E T="03">i.e.,</E>
                         “peak” concentrations). However, most of these studies examined exposure concentrations considerably higher than are typically measured in areas meeting the standards (U.S. EPA, 2020b, section 3.2.3.1). In particular, controlled human exposure studies often reported statistically significant effects on one or more indicators of cardiovascular function following 2-hour exposures to PM
                        <E T="52">2.5</E>
                         concentrations at and above 120 μg/m

                         for vascular impairment, the effect shown to be most consistent across studies). To provide insight into what these studies may indicate regarding the primary PM
                        <E T="52">2.5</E>
                         standards, the 2020 PA (U.S. EPA, 2020b, p. 3-49) noted that 2-hour ambient concentrations of PM

                         at monitoring sites meeting the current standards almost never exceeded 32 μg/m

                         concentrations, beyond the protection provided by the combination of the 24-hour and the annual standards (U.S. EPA, 2020b, section 3.2.3.1; 85 FR 82716, December 18, 2020).

                        With respect to the epidemiologic evidence, the then-Administrator noted that the studies did not indicate that associations in those studies were strongly influenced by exposures to peak concentrations in the air quality distribution and thus did not indicate the need for additional protection against short-term exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations (U.S. EPA, 2020b, section 3.5.1). The then-Administrator noted that this was consistent with CASAC consensus support for retaining the current 24-hour standard. Thus, the then-Administrator concluded that the 24-hour standard with its level of 35 µg/m
                        <SU>3</SU>
                         was adequate to provide supplemental protection (
                        <E T="03">i.e.,</E>
                         beyond that provided by the annual standard alone) against short-term exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations (85 FR 82716, December 18, 2020).

                    <P>
                        With regard to the level of the annual standard, the then-Administrator recognized that the annual standard, with its form based on the arithmetic mean concentration, was most appropriately meant to limit the “typical” daily and annual exposures that were most strongly associated with the health effects observed in epidemiologic studies. However, the then-Administrator also noted that while epidemiologic studies examined associations between distributions of PM
                        <E T="52">2.5</E>
                         air quality and health outcomes, they did not identify particular PM
                        <E T="52">2.5</E>
                         exposures that cause effects and thus, they could not alone identify a specific level at which the standard should be set, as such a determination necessarily required the then-Administrator's judgment. Thus, consistent with the approaches in previous NAAQS reviews, the then-Administrator recognized that any approach that used epidemiologic information in reaching decisions on what standards are appropriate necessarily required judgments about how to translate the information from the epidemiologic studies into a basis for appropriate standards. This approach included consideration of the uncertainties in the reported associations between daily or annual average PM
                        <E T="52">2.5</E>
                         exposures and mortality or morbidity in the epidemiologic studies. Such an approach is consistent with setting standards that are neither more nor less stringent than necessary, recognizing that a zero-risk standard is not required by the Clean Air Act (CAA) (85 FR 82716, December 18, 2020).

                        The then-Administrator emphasized uncertainties and limitations that were present in epidemiologic studies in previous reviews and persisted in the 2020 review. These uncertainties 
                        <PRTPAGE P="16222"/>
                        included exposure measurement error, potential confounding by copollutants, increasing uncertainty of associations at lower PM
                        <E T="52">2.5</E>
                         concentrations, and heterogeneity of effects across different cities or regions (85 FR 82716, December 18, 2020). The then-Administrator also noted the advice given by the CASAC on this matter. As described in section I.C.5 above, the CASAC did not reach consensus on the adequacy of the primary annual PM
                        <E T="52">2.5</E>
                         standard. “Some CASAC members” expressed support for retaining the primary annual PM
                        <E T="52">2.5</E>
                         standard while “other members” expressed support for revising that standard in order to increase public health protection (Cox, 2019b, p. 1 of consensus letter). The CASAC members who supported retaining the annual standard expressed their concerns with the epidemiologic studies, asserting that these studies did not provide a sufficient basis for revising the existing standards. They also identified several key concerns regarding the associations reported in epidemiologic studies and concluded that “while the data on associations should certainly be carefully considered, this data should not be interpreted more strongly than warranted based on its methodological limitations” (Cox, 2019b, p. 8 consensus responses).

                    <P>
                        Taking into consideration the views expressed by the CASAC members who supported retaining the annual standard, the then-Administrator recognized that epidemiologic studies examined associations between distributions of PM
                        <E T="52">2.5</E>
                         air quality and health outcomes, and they did not identify particular PM
                        <E T="52">2.5</E>
                         exposures that cause effects (U.S. EPA, 2020b, section 3.1.2). While the Administrator remained concerned about placing too much weight on epidemiologic studies to inform conclusions on the adequacy of the primary standards, he noted the approach to considering such studies in the 2012 review. In the 2012 review, it was noted that the evidence of an association in any epidemiologic study was “strongest at and around the long-term average where the data in the study are most concentrated” (78 FR 3140, January 15, 2013). In considering the characterization of epidemiologic studies, the then-Administrator viewed that when assessing the mean concentrations of the key short-term and long-term epidemiologic studies in the U.S. that used ground-based monitoring (
                        <E T="03">i.e.,</E>
                         those studies where the mean is most directly comparable to the current annual standard), the majority of studies had mean concentrations at or above the level of the existing annual standard, with the mean of the study-reported means or medians equal to 13.5 µg/m
                        <SU>3</SU>
                        , a concentration level above the existing level of the primary annual standard of 12 µg/m
                        <SU>3</SU>
                        . The then-Administrator further noted his caution in directly comparing the reported study mean values to the standard level given that study-reported mean concentrations, by design, are generally lower than the design value of the highest monitor in an area, which determines compliance. In the 2020 PA, analyses of recent air quality in U.S. CBSAs indicated that maximum annual PM
                        <E T="52">2.5</E>
                         design values for a given three-year period were often 10% to 20% higher than average monitored concentrations (
                        <E T="03">i.e.,</E>
                         averaged across multiple monitors in the same CBSA) (U.S. EPA, 2020b, Appendix B, section B.7). He further noted his concern in placing too much weight on any one epidemiologic study but instead judged that it was more appropriate to focus on the body of studies together and therefore noted the calculation of the mean of study-reported means (or medians). Thus, while the then-Administrator was cautious in placing too much weight on the epidemiologic evidence alone, he noted that: (1) The reported mean concentration in the majority of the key U.S. epidemiologic studies using ground-based monitoring data were above the level of the existing annual standard; (2) the mean of the reported study means (or medians) (
                        <E T="03">i.e.,</E>
                         13.5 µg/m
                        <SU>3</SU>
                        ) was above the level of the current standard;

                        <FTREF/>
                         (3) air quality analyses showed the study means to be lower than their corresponding design values by 10-20%; and (4) these analyses must be considered in light of uncertainties inherent in the epidemiologic evidence. When taken together, the then-Administrator judged that, even if it were appropriate to place more weight on the epidemiologic evidence, this information did not call into question the adequacy of the current standards (85 FR 82716-17, December 18, 2020).

                        In addition to the evidence, the then-Administrator also considered the potential implications of the risk assessment. He noted that all risk assessments have limitations and that he remained concerned about the uncertainties in the underlying epidemiologic data used in the risk assessment. The then-Administrator also noted that in previous reviews, these uncertainties and limitations have often resulted in less weight being placed on quantitative estimates of risk than on the underlying scientific evidence itself (
                        <E T="03">e.g.,</E>
                         78 FR 3086, 3098-99, January 15, 2013). These uncertainties and limitations included uncertainty in the shapes of C-R functions, particularly at low concentrations; uncertainties in the methods used to adjust air quality; and uncertainty in estimating risks for populations, locations and air quality distributions different from those examined in the underlying epidemiologic study (U.S. EPA, 2020b, section 3.3.2.4). Additionally, the then-Administrator noted similar concern expressed by some members of the CASAC who support retaining the existing standards; they highlighted similar uncertainties and limitations in the risk assessment (Cox, 2019b). In light of all of this, the then-Administrator judged it appropriate to place little weight on quantitative estimates of PM
                        <E T="52">2.5</E>
                        -associated mortality risk in reaching conclusions about the level of the primary PM

                    <P>
                        The then-Administrator additionally considered an emerging body of evidence from accountability studies that examined past reductions in ambient PM
                        <E T="52">2.5</E>
                         and the degree to which those reductions resulted in public health improvements. While the then-Administrator agreed with public commenters that well-designed and conducted accountability studies can be informative, he viewed the interpretation of such studies in the context of the primary PM
                        <E T="52">2.5</E>
                         standards as complicated by the fact that some of the available studies had not evaluated PM
                        <E T="52">2.5</E>
                         specifically (
                        <E T="03">e.g.,</E>
                         as opposed to PM
                        <E T="52">10</E>
                         or total suspended particulates), did not show changes in PM

He further recognized that the small number of available studies that did report public health improvements following past declines in ambient PM
                        <E T="52">2.5</E>
                         had not examined air quality meeting the existing standards (U.S. EPA, 2020b, Table 3-3). This included U.S. studies that reported increased life expectancy, decreased mortality, and decreased respiratory effects following past declines in ambient PM
                        <E T="52">2.5</E>
                         concentrations. Such studies examined “starting” annual average PM

                         concentrations (
                        <E T="03">i.e.,</E>
                         prior to the reductions being evaluated) ranging from about 13.2 to &gt;20µg/m

                         in locations meeting the existing standards, together with his broader concerns regarding the lack of experimental studies examining PM
                        <E T="52">2.5</E>
                         exposures typical of areas meeting the existing standards, the then-Administrator judged that there was considerable uncertainty in the potential for increased public health protection from further reductions in ambient PM
                        <E T="52">2.5</E>
                         concentrations beyond those achieved under the existing primary PM
                        <E T="52">2.5</E>
                         standards (85 FR 82717, December 18, 2020).

                    <P>
                        When the above considerations were taken together, the then-Administrator concluded that the scientific evidence assessed in the 2019 ISA, together with the analyses in the 2020 PA based on that evidence and consideration of CASAC advice and public comments, did not call into question the adequacy of the public health protection provided by the existing annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards. In particular, the then-Administrator judged that there was considerable uncertainty in the potential for additional public health improvements from reducing ambient PM
                        <E T="52">2.5</E>
                         concentrations below the concentrations achieved under the existing primary standards and that, therefore, standards more stringent than the existing standards (
                        <E T="03">e.g.,</E>
                         with lower levels) were not supported. That is, he judged that more stringent standards would be more than requisite to protect the public health with an adequate margin of safety. This judgment reflected the Administrator's consideration of the uncertainties in the potential implications of the lower end of the air quality distributions from the epidemiologic studies due in part to the lack of supporting evidence from experimental studies and retrospective accountability studies conducted at PM
                        <E T="52">2.5</E>
                         concentrations meeting the existing standards (85 FR 82717, December 18, 2020).

                        In reaching this conclusion in the 2020 review, the then-Administrator judged that the existing standards provided an adequate margin of safety. With respect to the annual standard, the level of 12 µg/m
                        <SU>3</SU>
                         was below the lowest “starting” concentration (
                        <E T="03">i.e.,</E>
                         13.2 µg/m
                        <SU>3</SU>
                        ) in the available accountability studies that showed public health improvements attributable to reductions in ambient PM
                        <E T="52">2.5</E>
                        . In addition, while the then-Administrator placed less weight on the epidemiologic evidence for selecting a standard, he noted that the level of the annual standard was below the reported mean (and median) concentrations in the majority of the key U.S. epidemiologic studies using ground-based monitoring data (noting that these means tend to be 10-20% lower than their corresponding area design values which is the more relevant metric when considering the level of the standard) and below the mean of the reported means (or medians) of these studies (
                        <E T="03">i.e.,</E>
                         13.5 µg/m
                        <SU>3</SU>
                        ). In addition, the then-Administrator recognized that concentrations in areas meeting the existing 24-hour and annual standards remained well-below the PM
                        <E T="52">2.5</E>
                         exposure concentrations consistently shown to elicit effects in human exposure studies (85 FR 82717-82718, December 18, 2020).

                        In addition, based on the then-Administrator's review of the science in the 2020 review, including controlled human exposure studies examining effects following short-term PM
                        <E T="52">2.5</E>
                         exposures, the epidemiologic studies, and accountability studies conducted at levels just above the existing annual standard, he judged that the degree of public health protection provided by the existing annual standard is not greater than warranted. This judgment, together with the fact that no CASAC member expressed support for a less stringent standard, led the then- Administrator to conclude that standards less stringent than the existing standards (
                        <E T="03">e.g.,</E>
                         with higher levels) were also not supported (85 FR 82718, December 18, 2020).

                        In reaching his final decision in the 2020 review, the then-Administrator concluded that the scientific evidence and technical information continued to support the existing annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards. This conclusion reflected the then-Administrator's view that there were important limitations and uncertainties that remained in the evidence. The then-Administrator concluded that these limitations contributed to considerable uncertainty regarding the potential public health implications of revising the existing primary PM

                         standards. Given this uncertainty, and noting the advice from some CASAC members, he concluded that the primary PM

                        ), when taken together, remained requisite to protect the public health. Therefore, in the 2020 review, the Administrator reached the conclusion that the primary 24-hour and annual PM

                         standards, together, were requisite to protect public health from fine particles with an adequate margin of safety, including the health of at-risk populations, and retained the standards, without revision (85 FR 82718, December 18, 2020).

                    <P>
                        The information summarized here and further detailed in section II.B of the proposal (88 FR 5580, January 27, 2023), is an overview of the policy-relevant aspects of the health effects evidence available in this reconsideration; the assessment of this evidence is documented in the 2019 ISA (U.S. EPA, 2019a) and ISA Supplement (U.S. EPA, 2022a) and its policy implications are further discussed in the 2022 PA (U.S. EPA, 2022b). While the 2019 ISA provides the broad scientific foundation for this reconsideration, additional literature has become available since the cutoff date of the 2019 ISA that expands the body of evidence related to mortality and cardiovascular effects for both short- and long-term PM
                        <E T="52">2.5</E>
                         exposure, which can inform the Administrator's judgment on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards. As such, the ISA Supplement builds on the information presented within the 2019 ISA with a targeted identification and evaluation of new scientific information (U.S. EPA, 2022a, section 1.2). The ISA Supplement focuses on PM
                        <E T="52">2.5</E>
                         health effects evidence where the 2019 ISA concludes a “causal relationship,” because such health effects are given the most weight in an Administrator's decisions in a NAAQS review. As such, in selecting the health effects to evaluate within the ISA Supplement (
                        <E T="03">i.e.,</E>
                         newly available evidence related to short- and long-term PM

                         exposure and mortality and cardiovascular effects), the primary rationale is based on the causality determinations for health effect categories presented in the 2019 PM ISA, and the subsequent use of the health effects evidence in the 2020 PM PA. Specifically, U.S. and Canadian epidemiologic studies for mortality and cardiovascular effects, along with controlled human exposure studies associated with cardiovascular effects at near ambient concentrations, were considered to be of greatest utility in informing the Administrator's conclusions on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards. Additionally, studies examining associations outside the U.S. or Canada reflect air quality and exposure patterns that may be less typical of the U.S., and thus less likely to be informative for purposes of reviewing the NAAQS (U.S. EPA, 2022b, p.1-3). While the ISA Supplement does not include information for health effects other than mortality and cardiovascular effects, the 
                        <PRTPAGE P="16224"/>
                        scientific evidence for other health effect categories is evaluated in the 2019 ISA, which in combination with the ISA Supplement represents the complete scientific record for the reconsideration of the 2020 final decision.

                        The ISA Supplement also assessed accountability studies because these types of epidemiologic studies were part of the body of evidence that was a focus of the 2020 review. Accountability studies inform our understanding of the potential for public health improvements as ambient PM
                        <E T="52">2.5</E>
                         concentrations have declined over time. Further, the ISA Supplement considered studies that employed statistical approaches that attempt to more extensively account for confounders and are more robust to model misspecification (
                        <E T="03">i.e.,</E>
                         used alternative methods for confounder control),

                         given that such studies were highlighted by the CASAC and identified in public comments in the 2020 review. Since the literature cutoff date for the 2019 ISA, multiple accountability studies and studies that employ alternative methods for confounder control have become available for consideration in the ISA Supplement and, subsequently, in this reconsideration.

                             As noted in the ISA Supplement (U.S. EPA, 2022a, p. 1-3): “In the peer-reviewed literature, these epidemiologic studies are often referred to as causal inference studies or studies that used causal modeling methods. For the purposes of this Supplement, this terminology is not used to prevent confusion with the main scientific conclusions (

                             the causality determinations) presented within an ISA. In addition, as is consistent with the weight-of-evidence framework used within ISAs and discussed in the Preamble to the Integrated Science Assessments, an individual study on its own cannot inform causality, but instead represents a piece of the overall body of evidence.”

                        The ISA Supplement also considered recent health effects evidence that addresses key scientific issues where the literature has expanded since the completion of the 2019 ISA.

                         The 2019 ISA evaluated a couple of controlled human exposure studies that investigated the effect of exposure to near-ambient concentrations of PM
                        <E T="52">2.5</E>
                         (U.S. EPA, 2019a, section 6.1.10 and 6.1.13). The ISA Supplement adds to this limited evidence, including a recent study conducted in young healthy individuals exposed to near-ambient PM

                         concentrations (U.S. EPA, 2022a, section 3.3.1). Given the importance of identifying populations at increased risk of PM

                        -related effects, the ISA Supplement also included epidemiologic or exposure studies that examined whether there is evidence of exposure or risk disparities by race/ethnicity or SES. These types of studies provide additional information related to factors that may increase risk of PM

                        -related health effects and provide additional evidence for consideration by the Administrator in reaching conclusions regarding the adequacy of the current standards. In addition, the ISA Supplement evaluated studies that examined the relationship between short- and long-term PM

                         exposures and SARS-CoV-2 infection and/or COVID-19 death, as these studies are a new area of research and were raised by a number of public commenters in the 2020 review.

In considering the available scientific evidence, the sections below, and in more detail in section II.B.1 of the proposal (88 FR 5580, January 27, 2023), summarize the relationships between long-and short-term PM

For these outcomes, the 2019 ISA concluded that the evidence supports either a “causal” or a “likely to be causal” relationship.

                        In the 2012 review, the 2009 ISA reported that the evidence was “sufficient to conclude that the relationship between long-term PM
                        <E T="52">2.5</E>
                         exposures and mortality is causal” (U.S. EPA, 2009a, p. 7-96). The strongest evidence supporting this conclusion was provided by epidemiologic studies, particularly those examining two seminal cohorts, the American Cancer Society (ACS) cohort and the Harvard Six Cities cohort. Analyses of the Harvard Six Cities cohort included evidence indicating that reductions in ambient PM
                        <E T="52">2.5</E>
                         concentrations are associated with reduced mortality risk (Laden et al., 2006) and increases in life expectancy (Pope et al., 2009). Further support was provided by other cohort studies conducted in North America and Europe that reported positive associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and mortality (U.S. EPA, 2019a).

                         exposures and mortality. These studies add support for associations with all-cause and total (non-accidental) mortality,

                        <FTREF/>
                         as well as with specific causes of mortality, including cardiovascular disease and respiratory disease (U.S. EPA, 2019a, section 11.2.2). Several of these studies conducted analyses over longer study durations and periods of follow-up than examined in the original ACS and Harvard Six Cities cohort studies and continue to report positive associations between long-term exposure to PM
                        <E T="52">2.5</E>
                         and mortality (U.S. EPA, 2019a, section 11.2.2.1; Figures 11-18 and 11-19). In addition to studies focusing on the ACS and Harvard Six Cities cohorts, additional studies examining other cohorts also provide evidence of consistent, positive associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and mortality across a wide range of demographic groups (

                        In addition to those cohort studies evaluated in the 2019 ISA, recent North American cohort studies evaluated in the ISA Supplement continue to examine the relationship between long-term PM

                         exposure and mortality and report consistent, positive, and statistically significant associations.

                        Furthermore, studies evaluated in the 2019 ISA and the ISA Supplement that examined cause-specific mortality expand upon previous research that found consistent, positive associations between PM
                        <E T="52">2.5</E>
                         exposure and specific mortality outcomes, which include cardiovascular and respiratory mortality, as well as other mortality outcomes. For cardiovascular-related mortality, the evidence evaluated in the ISA Supplement is consistent with the evidence evaluated in the 2019 ISA with recent studies reporting positive associations with long-term PM
                        <E T="52">2.5</E>
                         exposure. When evaluating cause-specific cardiovascular mortality, recent studies reported positive associations for a number of outcomes, such as ischemic heart disease (IHD) and stroke mortality (U.S. EPA, 2022a, Figure 3-23). Moreover, recent studies also provide some initial evidence that individuals with pre-existing health conditions, such as heart failure and diabetes, are at an increased risk of PM

                        -related health effects (U.S. EPA, 2022a, section 3.2.2.4) and that these individuals have a higher risk of mortality overall, which was previously only examined in studies that used stratified analyses rather than a cohort of people with an underlying health condition (U.S. EPA, 2022a, section 3.2.2.4). With regard to respiratory mortality, epidemiologic studies evaluated in the 2019 ISA and ISA Supplement continue to provide support for associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and respiratory mortality (U.S. EPA, 2019a, section 5.2.10; U.S. EPA, 2022a, Table 3-2).

                        A series of epidemiologic studies evaluated in the 2019 ISA tested the hypothesis that past reductions in ambient PM

                         concentrations are associated with increased life expectancy or a decreased mortality rate and report that reductions in ambient PM

                        Since the literature cutoff date for the 2019 ISA, a few epidemiologic studies were published that examined the relationship between long-term PM

In addition, multiple epidemiologic studies that implemented alternative methods for confounder control and were published since the literature cutoff date of the 2019 ISA were evaluated in the ISA Supplement (U.S. EPA, 2022a, section 3.2.2.3). These studies used a variety of statistical methods including generalized propensity score (GPS), inverse probability weighting (IPW), and difference-in-difference (DID) to reduce uncertainties related to confounding bias in the association between long-term PM

                        The 2019 ISA and ISA Supplement also evaluated the degree to which recent studies examining the relationship between long-term PM

                         exposure and mortality addressed key policy-relevant issues and/or previously identified data gaps in the scientific evidence, including methods to estimate exposure, methods to control for confounding (

With respect to exposure assessment, based on its evaluation of the evidence, the 2019 ISA concludes that positive associations between long-term PM

(2015) report that correction for bias due to exposure measurement error increases the magnitude of the hazard ratios (confidence intervals widen but the association remains statistically significant), suggesting that failure to correct for exposure measurement error could result in attenuation or underestimation of risk estimates.

                        The 2019 ISA additionally concludes that positive associations between long-term PM

                         exposures and mortality are robust across statistical models that use different approaches to control for confounders or different sets of confounders (U.S. EPA, 2019a, sections 11.2.3 and 11.2.5), across diverse geographic regions and populations, and across a range of temporal periods including periods of declining PM concentrations (U.S. EPA, 2019a, sections 11.2.2.5 and 11.2.5.3). Additional evidence further demonstrates that associations with mortality remain robust in copollutants analyses (U.S. EPA, 2019a, section 11.2.3), and that associations persist in analyses restricted to long-term exposures (annual average PM
                        <E T="52">2.5</E>

                         (Shi et al., 2016), indicating that risks are not disproportionately driven by the upper portions of the air quality distribution. Recent studies evaluated in the ISA Supplement further assess potential copollutant confounding and indicate that while there is some evidence of potential confounding of the PM

                        Additionally, a few studies use statistical techniques to reduce uncertainties related to potential confounding to further inform conclusions on causality for long-term PM

                         exposure and mortality, as further detailed in section II.B.1.a.i of the proposal (88 FR 5582, January 27, 2023), studies by Greven et al. (2011), Pun et al. (2017), and Eum et al. (2018) completed sensitivity analyses as part of their Medicare cohort study in which they decompose ambient PM

                         into “spatial” and “spatiotemporal” components in order to evaluate the potential for bias due to unmeasured spatial confounding. Pun et al. (2017) observed positive associations for the “temporal” variation model and approximately null associations for the “spatiotemporal” variation model for all causes of death except for COPD mortality. The difference in the results of these two models for most causes of death suggests the presence of unmeasured confounding, though the authors do not indicate anything about the direction or magnitude of this bias. It is important to note that the “temporal” and “spatiotemporal” coefficients are not directly comparable to the results of other epidemiologic studies when examined individually and can only be used in comparison with one another to evaluate the potential for unmeasured confounding bias. Eum et al. (2018) and Wu et al. (2020) also attempted to address long-term trends and meteorological variables as potential confounders and found that not adjusting for temporal trends could overestimate the association, while effect estimates in analyses that excluded meteorological variables remained unchanged compared to the main analyses. While results of these analyses suggest the presence of some unmeasured confounding, they do not indicate the direction or magnitude of the bias.

                         exposure is whether C-R relationships are linear across the range of concentrations or if nonlinear relationships exist along any part of this range. Studies evaluated in the 2019 ISA and the ISA Supplement examine this issue, and continue to provide evidence of linear, no-threshold relationships between long-term PM
                        <E T="52">2.5</E>

Across the studies evaluated in the 2019 ISA and the ISA Supplement, a variety of statistical methods have been used to assess whether there is evidence of deviations in linearity (U.S. EPA, 2019a, Table 11-7; U.S. EPA, 2022a, section 2.2.3.2). Studies have also conducted cut-point analyses that focus on examining risk at specific ambient PM

                         concentrations. Generally, the evidence remains consistent in supporting a no-threshold relationship, and in supporting a linear relationship for PM

There was also some limited evidence indicating that the slope of the C-R function may be steeper (supralinear) at lower concentrations for cardiovascular mortality (U.S. EPA, 2022a, section 3.1.1.2.6).

The evaluation of cause-specific mortality found that effect estimates were larger in magnitude, but also had larger confidence intervals, for respiratory mortality compared to cardiovascular mortality. Although the largest mortality risk estimates were for respiratory mortality, the interpretation of the results was complicated by the limited coherence from studies of respiratory morbidity. However, the evidence from studies of cardiovascular morbidity provided both coherence and biological plausibility for the relationship between short-term PM

                        Some studies have expanded the examination of potential confounders including long-term temporal trends, weather, and co-occurring pollutants. Mortality associations were found to remain positive, although in some cases were attenuated, when using different approaches to account for temporal trends or weather covariates (
                        <E T="03">e.g.,</E>
                         U.S. EPA, 2019a, section 11.1.5.1). For example, Sacks et al. (2012) examined the influence of model specification using the approaches for confounder adjustment from models employed in several multicity studies within the context of a common data set (U.S. EPA, 2019a, section 11.1.5.1). These models use different approaches to control for long-term temporal trends and the potential confounding effects of weather. The authors report that associations between daily PM
                        <E T="52">2.5</E>
                         and cardiovascular mortality were similar across models, with the percent increase in mortality ranging from 1.5-2.0% (U.S. EPA, 2019a, Figure 11-4). Thus, alternative approaches to controlling for long-term temporal trends and for the potential confounding effects of weather may influence the magnitude of the association between PM
                        <E T="52">2.5</E>
                         exposures and mortality but have not been found to influence the direction of the observed association (U.S. EPA, 2019a, section 11.1.5.1). Taken together, the 2019 ISA and the ISA Supplement conclude that recent multicity studies conducted in the U.S., Canada, Europe, and Asia continue to provide consistent evidence of positive associations between short-term PM
                        <E T="52">2.5</E>
                         exposures and total mortality across studies that use different approaches to control for the potential confounding effects of weather (

                        With regard to copollutants, studies evaluated in the 2019 ISA provide additional evidence that associations between short-term PM
                        <E T="52">2.5</E>
                         exposures and mortality remain positive and relatively unchanged in copollutant models with both gaseous pollutants and PM

                         (U.S. EPA, 2019a, section 11.1.4). Additionally, the low (r &lt; 0.4) to moderate correlations (r = 0.4-0.7) between PM

                         having an independent effect on mortality (U.S. EPA, 2019a, section 11.1.4). Consistent with the studies evaluated in the 2019 ISA, studies evaluated in the ISA Supplement that used data from more recent years also indicate that associations between short-term PM
                        <E T="52">2.5</E>
                         exposure and mortality remain unchanged in copollutant models. However, the evidence indicates that the association could be larger in magnitude in the presence of some copollutants such as oxidant gases (Lavigne et al., 2018; Shin et al., 2021).

                        The generally positive associations reported with mortality are supported by a small group of studies employing alternative methods for confounder control or quasi-experimental statistical approaches (U.S. EPA, 2019a, section 11.1.2.1). For example, two studies by Schwartz et al. report associations between PM
                        <E T="52">2.5</E>
                         instrumental variables and mortality (U.S. EPA, 2019a, Table 11-2), including in an analysis limited to days with 24-hour average PM
                        <E T="52">2.5</E>
                         concentrations &lt;30 μg/m
                        <SU>3</SU>
                         (Schwartz et al., 2015; Schwartz et al., 2017). In addition to the main analyses, these studies conducted Granger-like causality tests as sensitivity analyses to examine whether there was evidence of an association between mortality and PM
                        <E T="52">2.5</E>
                         after the day of death, which would support the possibility that unmeasured confounders were not accounted for in the statistical model. Neither study reports evidence of an association with PM
                        <E T="52">2.5</E>
                         after death (
                        <E T="03">i.e.,</E>
                         they do not indicate unmeasured confounding). Yorifuji et al. (2016) conducted a quasi-experimental study to examine whether a specific regulatory action in Tokyo, Japan (
                        <E T="03">i.e.,</E>
                         a diesel emission control ordinance) resulted in a subsequent reduction in daily mortality (Yorifuji et al., 2016). The authors reported a reduction in mortality in Tokyo due to the ordinance, compared to Osaka, which did not have a similar diesel emission control ordinance in place. In another study, Schwartz et al. (2018) utilized three statistical methods including instrumental variable analysis, a negative exposure control, and marginal structural models to estimate the association between PM
                        <E T="52">2.5</E>
                         and daily mortality (Schwartz et al., 2018). Results from this study continue to support a relationship between short-term PM
                        <E T="52">2.5</E>
                         exposure and mortality. Additional epidemiologic studies evaluated in the ISA Supplement that employed alternative methods for confounder control to examine the association between short-term PM

                    <P>
                        The positive associations for total mortality reported across the majority of studies evaluated are further supported by cause-specific mortality analyses, which generally report consistent, positive associations with both cardiovascular and respiratory mortality (U.S. EPA, 2019a, section 11.1.3). Recent multicity studies evaluated in the ISA Supplement add to the body of evidence indicating a relationship between short-term PM
                        <E T="52">2.5</E>
                         exposure and cause-specific mortality, with more variability in the magnitude and precision of associations for respiratory mortality (U.S. EPA, 2022a; Figure 3-14). For both cardiovascular and respiratory mortality, there has been a limited assessment of potential copollutant confounding, though initial evidence indicates that associations remain positive and relatively unchanged in models with gaseous pollutants and PM
                        <E T="52">10-2.5</E>
                        , which further supports the copollutant analyses conducted for total mortality. The strong evidence for ischemic events and heart failure, as detailed in the assessment of cardiovascular morbidity (U.S. EPA, 2019a, Chapter 6), provides biological plausibility for PM
                        <E T="52">2.5</E>
                        -related cardiovascular mortality, which comprises the largest percentage of total mortality (
                        <E T="03">i.e.,</E>
                         ~33%) (NHLBI, 2017). Although there is evidence for exacerbations of COPD and asthma, the collective body of respiratory morbidity evidence provides limited biological plausibility for PM
                        <E T="52">2.5</E>
                        -related respiratory mortality (U.S. EPA, 2019a, Chapter 5).

                        In the 2009 ISA, one of the main uncertainties identified was the regional and city-to-city heterogeneity in PM

                        -mortality associations. Studies evaluated in the 2019 ISA examine both city-specific as well as regional characteristics to identify the underlying contextual factors that could contribute to this heterogeneity (U.S. EPA, 2019a, section 11.1.6.3). Analyses focusing on effect modification of the PM

                         components and city specific differences in composition and sources indicate some differences in the PM

                         composition and sources across cities and regions, but these differences do not fully explain the observed heterogeneity. Additional studies find that factors related to potential exposure differences, such as housing stock and commuting, as well as city specific factors (
                        <E T="03">e.g.,</E>
                         land use, port volume, and traffic information), may also explain some of the observed heterogeneity (U.S. EPA, 2019a, section 11.1.6.3). Collectively, studies evaluated in the 2019 ISA and the ISA Supplement indicate that the heterogeneity in PM
                        <E T="52">2.5</E>
                         mortality risk estimates cannot be attributed to one factor, but instead a combination of factors including, but not limited to, PM composition and sources as well as community characteristics that could influence exposures (U.S. EPA, 2019a, section 11.1.12; U.S. EPA, 2022a, section 3.2.1.2.1).

                        Consistent with the evidence assessed in the 2009 ISA, the 2019 ISA concludes that recent studies, together with the evidence available in previous reviews, support a causal relationship between long-term exposure to PM

Additionally, recent epidemiologic studies published since the completion of the 2019 ISA and evaluated in the ISA Supplement expands the body of evidence and further supports such a conclusion (U.S. EPA, 2022a).

Additionally, studies evaluated in the ISA Supplement report positive associations among those with pre-existing conditions, among patients followed after a cardiac event procedure, and among those with a first hospital admission for heart attacks among older adults enrolled in Medicare (U.S. EPA, 2022a, sections 3.1.1 and 3.1.2).

                         exposure and cardiovascular effects by using methods that reduce uncertainties related to potential confounding through statistical and/or study design approaches. For example, to control for potential confounding Wei et al. (2021) used a doubly robust additive model (DRAM) and found an association between long-term exposure to PM

                         and cardiovascular effects, including MI, stoke, and atrial fibrillation, among the Medicare population. For example, an accountability study by Henneman et al. (2019) utilized a difference-in-difference (DID) approach to determine the relationship between coal-fueled power plant emissions and cardiovascular effects and found that reductions in PM

                        Positive associations reported in epidemiologic studies are supported by toxicological evidence evaluated in the 2019 ISA. The positive associations reported in epidemiologic studies are supported by toxicological evidence for increased plaque progression in mice following long-term exposure to PM

                         collected from multiple locations across the U.S. (U.S. EPA, 2019a, section 6.2.4.2). A small number of epidemiologic studies also report positive associations between long-term PM

                         exposure (U.S. EPA, 2019a, section 6.2.5.2). Similarly, a limited number of animal toxicological studies demonstrating a relationship between long-term PM

                         exposure and consistent increases in blood pressure in rats and mice are coherent with epidemiologic studies reporting positive associations between long-term exposure to PM

                        Additionally, a number of studies evaluated in the ISA Supplement focusing on morbidity outcomes, including those that focused on incidence of MI, atrial fibrillation (AF), stroke, and congestive heart failure (CHF), expand the evidence pertaining to the shape of the C-R relationship between long-term PM

These studies use statistical techniques that allow for departures from linearity (U.S. EPA, 2022a, Table 3-3), and generally support the evidence characterized in the 2019 ISA showing linear, no-threshold C-R relationship for most cardiovascular disease (CVD) outcomes. However, there is evidence for a sublinear or supralinear C-R relationship for some outcomes (U.S. EPA, 2022a, section 3.1.2.2.9).

                         exposure and cardiovascular morbidity (U.S. EPA, 2022a, section 3.1.2.2). Associations with coronary heart disease (CHD), stroke and atherosclerosis progression were observed in several additional epidemiologic studies, providing coherence with the mortality findings. Results from copollutant models generally support an independent effect of PM

Animal toxicological studies provided coherence and biological plausibility for the positive associations reported with MI, ED visits, and hospital admissions.

This includes generally positive associations observed in multicity epidemiologic studies of emergency department visits and hospital admissions for IHD, heart failure (HF), and combined cardiovascular-related endpoints. In particular, nationwide studies of older adults (65 years and older) using Medicare records report positive associations between PM

                         exposures and hospital admissions for HF (U.S. EPA, 2019a, section 6.1.3.1).

                        The ISA Supplement includes additional epidemiologic studies, published since the literature cutoff date for the 2019 ISA, including accountability analyses and epidemiologic studies that employ alternative methods for confounder control to evaluate the association between short-term PM

                        A number of controlled human exposure, animal toxicological, and epidemiologic panel studies provide evidence that PM
                        <E T="52">2.5</E>
                         exposure could plausibly result in IHD or HF through pathways that include endothelial dysfunction, arterial thrombosis, and arrhythmia (U.S. EPA, 2019a, section 6.1.1). The most consistent evidence from recent controlled human exposure studies is for endothelial dysfunction, as measured by changes in brachial artery diameter or flow mediated dilation. Multiple controlled human exposure studies that examined the potential for endothelial dysfunction report an effect of PM
                        <E T="52">2.5</E>
                         exposure on measures of blood flow (U.S. EPA, 2019a, section 6.1.13.2). However, these studies report variable results regarding the timing of the effect and the mechanism by which reduced blood flow occurs (
                        <E T="03">i.e.,</E>
                         availability vs sensitivity to nitric oxide). In addition, some controlled human exposure studies using CAPs report evidence for small increases in blood pressure (U.S. EPA, 2019a, section 6.1.6.3). Although not entirely consistent, there is also some evidence across controlled human exposure studies for conduction abnormalities/arrhythmia (U.S. EPA, 2019a, section 6.1.4.3), changes in heart rate variability (HRV) (U.S. EPA, 2019a, section 6.1.10.2), changes in hemostasis that could promote clot formation (U.S. EPA, 2019a, section 6.1.12.2), and increases in inflammatory cells and markers (U.S. EPA, 2019a, section 6.1.11.2). A recent study by Wyatt et al.

                        (2020), evaluated in the ISA Supplement, adds to the limited evidence base of controlled human exposure studies conducted at near ambient PM
                        <E T="52">2.5</E>
                         concentrations. The study, completed in healthy young adults subject to intermittent exercise, found some significant cardiovascular effects (

                         systematic inflammation markers, including C-reactive protein (CRP), and cardiac repolarization). Thus, when taken as a whole, controlled human exposure studies are coherent with epidemiologic studies in that they demonstrate that short-term exposures to PM
                        <E T="52">2.5</E>
                         may result in the types of cardiovascular endpoints that could lead to emergency department visits and hospital admissions for IHD or HF, as well as mortality in some people.

                        Animal toxicological studies published since the 2009 ISA and evaluated in the 2019 ISA also support a relationship between short-term PM
                        <E T="52">2.5</E>
                         exposure and cardiovascular effects. A study demonstrating decreased cardiac contractility and left ventricular pressure in mice is coherent with the results of epidemiologic studies that report associations between short-term PM
                        <E T="52">2.5</E>
                         exposure and heart failure (U.S. EPA, 2019a, section 6.1.3.3). In addition, and as with controlled human exposure studies, there is generally consistent evidence in animal toxicological studies for indicators of endothelial dysfunction (U.S. EPA, 2019a, section 6.1.13.3). Some studies in animals also provide evidence for changes in a number of other cardiovascular endpoints following short-term PM
                        <E T="52">2.5</E>
                         exposure including conduction abnormalities and arrhythmia (U.S. EPA, 2019a, section 6.1.4.4), changes in HRV (U.S. EPA, 2019a, section 6.1.10.3), changes in blood pressure (U.S. EPA, 2019a, section 6.1.6.4), and evidence for systemic inflammation and oxidative stress (U.S. EPA, 2019a, section 6.1.11.3).

                        In summary, evidence evaluated in the 2019 ISA extends the consistency and coherence of the evidence base evaluated in the 2009 ISA and prior assessments. Epidemiologic studies reporting robust associations in copollutant models are supported by direct evidence from controlled human exposure and animal toxicologic studies reporting independent effects of PM
                        <E T="52">2.5</E>
                         exposures on endothelial dysfunction as well as endpoints indicating impaired cardiac function, increased risk of arrhythmia, changes in HRV, increases in BP, and increases in indicators of systemic inflammation, oxidative stress, and coagulation (U.S. EPA, 2019, section 6.1.16). For some cardiovascular effects, there are inconsistencies in results across some animal toxicological, controlled human exposure, and epidemiologic panel studies, though this may be due to substantial differences in study design and/or study populations. Overall, the results from epidemiologic panel, controlled human exposure, and animal toxicological studies, in particular those related to endothelial dysfunction, impaired cardiac function, ST segment depression, thrombosis, conduction abnormalities, and changes in blood pressure provide coherence and biological plausibility for the consistent results from epidemiologic studies observing positive associations between short-term PM
                        <E T="52">2.5</E>
                         exposures and IHD and HF, and ultimately cardiovascular mortality. Overall, studies evaluated in the 2019 ISA support the conclusion of a causal relationship between short-term PM
                        <E T="52">2.5</E>
                         exposure and cardiovascular effects, which is supported and extended by evidence from recent epidemiologic studies evaluated in the ISA Supplement (U.S. EPA, 2022a, section 3.1.1.4).

                         exposure and changes in lung function or lung function growth in children. Biological plausibility was provided by a single animal toxicological study examining pre- and post-natal exposure to PM

Experimental evidence for other outcomes was also limited, with one animal toxicological study reporting that long-term exposure to PM

                         CAPs results in morphological changes in nasal airways of healthy animals. Other animal studies examined exposure to mixtures, such as motor vehicle exhaust and woodsmoke, and effects were not attributed specifically to the particulate components of the mixture.

                    <P>
                        Cohort studies evaluated in the 2019 ISA provided additional support for the relationship between long-term PM
                        <E T="52">2.5</E>
                         exposure and decrements in lung function growth (as a measure of lung development), indicating a robust and consistent association across study locations, exposure assessment methods, and time periods (U.S. EPA, 2019a, section 5.2.13). This relationship was further supported by a retrospective study that reports an association between declining PM
                        <E T="52">2.5</E>
                         concentrations and improvements in lung function growth in children (U.S. EPA, 2019a, section 5.2.11). Epidemiologic studies also examine asthma development in children (U.S. EPA, 2019a, section 5.2.3), with prospective cohort studies reporting generally positive associations, though several are imprecise (
                        <E T="03">i.e.,</E>
                         they report wide confidence intervals). Supporting evidence is provided by studies reporting associations with asthma prevalence in children, with childhood wheeze, and with exhaled nitric oxide, a marker of pulmonary inflammation (U.S. EPA, 2019a, section 5.2.13). Additionally, the 2019 ISA includes an animal toxicological study showing the development of an allergic phenotype and an increase in a marker of airway responsiveness supports the biological plausibility of the development of allergic asthma (U.S. EPA, 2019a, section 5.2.13). Other epidemiologic studies report a PM
                        <E T="52">2.5</E>
                        -related acceleration of lung function decline in adults, while improvement in lung function was observed with declining PM

                         concentrations (U.S. EPA, 2019a, section 5.2.11). A longitudinal study found declining PM
                        <E T="52">2.5</E>
                         concentrations are also associated with an improvement in chronic bronchitis symptoms in children, strengthening evidence reported in the 2009 ISA for a relationship between increased chronic bronchitis symptoms and long-term PM
                        <E T="52">2.5</E>
                         exposure (U.S. EPA, 2019a, section 5.2.11). A common uncertainty across the epidemiologic evidence is the lack of examination of copollutants to assess the potential for confounding. While there is some evidence that associations remain robust in models with gaseous pollutants, a number of these studies examining copollutant confounding were conducted in Asia, and thus have limited generalizability due to high annual pollutant concentrations.

                        When taken together, the 2019 ISA concludes that the epidemiologic evidence strongly supports a relationship with decrements in lung function growth asthma development in children, as well as increased bronchitis symptoms in children with asthma. Additionally, the epidemiologic

                        evidence strongly supports a relationship with an acceleration of lung function decline in adults, and with respiratory mortality and cause-specific respiratory mortality for COPD and respiratory infection (U.S. EPA, 2019a, p. 1-34). In support of the biological plausibility of associations reported in epidemiologic studies associated with respiratory health effects, animal toxicological studies evaluated in the 2019 ISA continue to provide direct evidence that long-term exposure to PM
                        <E T="52">2.5</E>
                         results in a variety of respiratory effects, including pulmonary oxidative stress, inflammation, and morphologic changes in the upper (nasal) and lower airways. Other results show that changes are consistent with the development of allergy and asthma, and with impaired lung development. Overall, the 2019 ISA concludes that “the collective evidence is sufficient to conclude that a causal relationship is likely to exist between long-term PM
                        <E T="52">2.5</E>

                         exposure and respiratory effects. This conclusion was based mainly on the epidemiologic evidence demonstrating positive associations with various respiratory effects. Specifically, the 2009 ISA described epidemiologic evidence as consistently showing PM
                        <E T="52">2.5</E>
                        -associated increases in hospital admissions and ED visits for COPD and respiratory infection among adults or people of all ages, as well as increases in respiratory mortality.

Studies examining copollutant models showed that PM

                         associations with respiratory effects were robust to inclusion of CO or SO

                         exposure on the respiratory system was provided by animal toxicological studies of PM

                         on respiratory health is also partially addressed by findings from animal toxicological studies evaluated in the 2019 ISA. Specifically, short-term exposure to PM

                         enhanced asthma-related responses in an animal model of allergic airways disease and enhanced lung injury and inflammation in an animal model of COPD (U.S. EPA, 2019a, sections 5.1.2.4.4 and 5.1.4.4.3). The experimental evidence provides biological plausibility for some respiratory-related endpoints, including limited evidence of altered host defense and greater susceptibility to bacterial infection as well as consistent evidence of respiratory irritant effects. However, animal toxicological evidence for other respiratory effects is inconsistent. A recent study evaluated in the ISA supplement by Wyatt et al. (2020) and conducted at near ambient PM

                        The 2009 ISA concluded that the overall body of evidence was “suggestive of a causal relationship between relevant PM
                        <E T="52">2.5</E>
                         exposures and cancer” (U.S. EPA, 2009a). This conclusion was based primarily on positive associations observed in a limited number of epidemiologic studies of lung cancer mortality. The few epidemiologic studies that had evaluated PM
                        <E T="52">2.5</E>
                         exposure and lung cancer incidence or cancers of other organs and systems generally did not show evidence of an association. Toxicological studies did not focus on exposures to specific PM size fractions, but rather investigated the effects of exposures to total ambient PM, or other source-based PM such as wood smoke. Collectively, results of in vitro studies were consistent with the larger body of evidence demonstrating that ambient PM and PM from specific combustion sources are mutagenic and genotoxic. However, animal inhalation studies 
                        <PRTPAGE P="16233"/>
                        found little evidence of tumor formation in response to chronic exposures. A small number of studies provided preliminary evidence that PM exposure can lead to changes in methylation of DNA, which may contribute to biological events related to cancer.

                        Since the completion of the 2009 ISA, additional cohort studies provide evidence that long-term PM
                        <E T="52">2.5</E>
                         exposure is positively associated with lung cancer mortality and with lung cancer incidence, and provide initial evidence for an association with reduced cancer survival (U.S. EPA, 2019a, section 10.2.5). Re-analyses of the ACS cohort using different years of PM
                        <E T="52">2.5</E>
                         data and follow up, along with various exposure assignment approaches, provide consistent evidence of positive associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and lung cancer mortality (U.S. EPA, 2019a, Figure 10-3). Additional support for positive associations with lung cancer mortality is provided by recent epidemiologic studies using individual level data to control for smoking status, as well as by studies of people who have never smoked (though such studies generally report wide confidence intervals due to the small number of lung cancer mortality cases within this population), and in additional analyses of cohorts that relied upon proxy measures to account for smoking status (U.S. EPA, 2019a, section 10.2.5.1.1). Although studies that evaluate lung cancer incidence, including studies of people who have never smoked, are limited in number, studies in the 2019 ISA generally report positive associations with long-term PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2019a, section 10.2.5.1.2). A subset of the studies focusing on lung cancer incidence also examined histological subtype, providing some evidence of positive associations for adenocarcinomas, the predominate subtype of lung cancer observed in people who have never smoked (U.S. EPA, 2019a, section 10.2.5.1.2). Associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and lung cancer incidence were found to remain relatively unchanged, though in some cases confidence intervals widened, in analyses that attempted to reduce exposure measurement error by accounting for length of time at residential address or by examining different exposure assignment approaches (U.S. EPA, 2019a, section 10.2.5.1.2).

                        To date, relatively few studies have evaluated the potential for copollutant confounding of the relationship between long-term PM
                        <E T="52">2.5</E>
                         exposure and lung cancer mortality or incidence. A small number of such studies have generally focused on O

                         associations remain relatively unchanged in copollutant models (U.S. EPA, 2019a, section 10.2.5.1.3). However, available studies have not systematically evaluated the potential for copollutant confounding by other gaseous pollutants or by other particle size fractions (U.S. EPA, 2019a, section 10.2.5.1.3).

                    <P>Compared to total (non-accidental) mortality (U.S. EPA, 2019a, section 10.2.4.1.4), fewer studies have examined the shape of the C-R curve for cause-specific mortality outcomes, including lung cancer. Several studies of lung cancer mortality and incidence have reported no evidence of deviations from linearity in the shape of the C-R relationship (Lepeule et al., 2012; Raaschou-Nielsen et al., 2013; Puett et al., 2014), though authors provided only limited discussions of results (U.S. EPA, 2019a, section 10.2.5.1.4).</P>

                         on lung cancer, the 2019 ISA notes evidence from experimental and epidemiologic studies demonstrating that PM
                        <E T="52">2.5</E>
                         exposure can lead to a range of effects indicative of mutagenicity, genotoxicity, and carcinogenicity, as well as epigenetic effects (U.S. EPA, 2019a, section 10.2.7). For example, both in vitro and in vivo toxicological studies have shown that PM
                        <E T="52">2.5</E>
                         exposure can result in DNA damage (U.S. EPA, 2019a, section 10.2.2). Although such effects do not necessarily equate to carcinogenicity, the evidence that PM exposure can damage DNA, and elicit mutations, provides support for the plausibility of epidemiologic associations exhibited with lung cancer mortality and incidence. Additional supporting studies indicate the occurrence of micronuclei formation and chromosomal abnormalities (U.S. EPA, 2019a, section 10.2.2.3), and differential expression of genes that may be relevant to cancer pathogenesis, following PM
                        <E T="52">2.5</E>
                         exposures. Experimental and epidemiologic studies that examine epigenetic effects indicate changes in DNA methylation, providing some support that PM
                        <E T="52">2.5</E>
                         exposure contributes to genomic instability (U.S. EPA, 2019a, section 10.2.3). Overall, there is limited evidence that long-term PM
                        <E T="52">2.5</E>
                         exposure is associated with cancers in other organ systems, though there is some evidence that PM

                         exposure may reduce survival in individuals with cancer (U.S. EPA, 2019a, section 10.2.7; U.S. EPA, 2022a, section 2.1.1.4.1).

                        Reflecting the very limited evidence available in the 2012 review, the 2009 ISA did not make a causality determination for long-term PM
                        <E T="52">2.5</E>
                         exposures and nervous system effects (U.S. EPA, 2009c). Since the 2012 review, this body of evidence has grown substantially (U.S. EPA, 2019, section 8.2). Animal toxicological studies assessed in in the 2019 ISA report that long-term PM
                        <E T="52">2.5</E>
                         exposures can lead to morphologic changes in the hippocampus and to impaired learning and memory. This evidence is consistent with epidemiologic studies reporting that long-term PM
                        <E T="52">2.5</E>
                         exposure is associated with reduced cognitive function (U.S. EPA, 2019a, section 8.2.5). Further, while the evidence is limited, the presence of early markers of Alzheimer's disease pathology has been demonstrated in rodents following long-term exposure to PM
                        <E T="52">2.5</E>
                         CAPs. These findings support reported associations with neurodegenerative changes in the brain (
                        <E T="03">i.e.,</E>
                         decreased brain volume), all-cause dementia, or hospitalization for Alzheimer's disease in a small number of epidemiologic studies (U.S. EPA, 2019a, section 8.2.6). Additionally, loss of dopaminergic neurons in the substantia nigra, a hallmark of Parkinson disease, has been reported in mice (U.S. EPA, 2019a, section 8.2.4), though epidemiologic studies provide only limited support for associations with Parkinson's disease (U.S. EPA, 2019a, section 8.2.6). Overall, the lack of consideration of copollutant confounding introduces some uncertainty in the interpretation of epidemiologic studies of nervous system effects, but this uncertainty is partly addressed by the evidence for an independent effect of PM
                        <E T="52">2.5</E>
                         exposures provided by experimental animal studies.

Biological plausibility is provided for the ASD findings by a study in mice that found inflammatory and morphologic changes in the corpus collosum and hippocampus, as well as ventriculomegaly (

                        Taken together, the 2019 ISA concludes that studies indicate long-term PM
                        <E T="52">2.5</E>
                         exposures can lead to effects on the brain associated with neurodegeneration (

                         neuroinflammation and reductions in brain volume), as well as cognitive effects in older adults (U.S. EPA, 2019a, Table 1-2). Animal toxicological studies provide evidence for a range of nervous system effects in adult animals, including neuroinflammation and oxidative stress, neurodegeneration, cognitive effects, and effects on neurodevelopment in young animals. The epidemiologic evidence is more limited, but studies generally support associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and changes in brain morphology, cognitive decrements and dementia. There is also initial, and limited, evidence for neurodevelopmental effects, particularly ASD. The consistency and coherence of the evidence supports the 2019 ISA's conclusion that “the collective evidence is sufficient to conclude that a causal relationship is likely to exist between long-term PM

The currently available evidence is “suggestive of, but not sufficient to infer, a causal relationship” for short-term UFP exposure and cardiovascular and respiratory effects and for short- and long-term UFP exposure and nervous system effects, primarily due to uncertainties and limitations in the evidence, specifically, variability across studies in the definition of UFPs and the exposure metric used (U.S. EPA, 2019a, P.3.1; U.S. EPA, 2022a, section 3.3.1.6.3). The causality determinations for the other health effect categories evaluated in the 2019 ISA are “inadequate to infer a causal relationship.” Additionally, this is the first time assessments of causality were conducted for short- and long-term UFP exposure and metabolic effects and long-term UFP exposure and nervous system effects (U.S. EPA, 2022a, Table ES-1).

                         can influence SARS-CoV-2 infection and COVID-19 death (U.S. EPA, 2022a, section 3.3.2.1). Additionally, several studies evaluated whether long-term PM

While there is initial evidence of positive associations with SARS-CoV-2 infection and COVID-19 death, uncertainties remain due to methodological issues that may influence the results, including: (1) The use of ecological study design; (2) studies were conducted during the ongoing pandemic when the etiology of COVID-19 was still not well understood (

                        Children make up a substantial fraction of the U.S. population, and often have unique factors that contribute to their increased risk of experiencing a health effect due to exposures to ambient air pollutants because of their continuous growth and development.

                         Children may be particularly at risk for health effects related to ambient PM

                         exposures compared with adults because they have (1) a developing respiratory system, (2) increased ventilation rates relative to body mass compared with adults, and (3) an increased proportion of oral breathing, particularly in boys, relative to adults (U.S. EPA, 2019a, section 12.5.1.1). There is strong evidence that demonstrates PM

                        In the U.S., older adults, often defined as adults 65 years of age and older, represent an increasing portion of the population and often have pre-existing diseases or conditions that may compromise biological function. While there is limited evidence to indicate that older adults have higher exposures than younger adults, older adults may receive higher doses of PM
                        <E T="52">2.5</E>
                         due to dosimetric differences. There is consistent evidence from studies of older adults demonstrating generally consistent positive associations in studies examining health effects from short- and long-term PM

                         exposure and cardiovascular or respiratory hospital admissions, emergency department visits, or mortality (U.S. EPA, 2019a, sections 6.1, 6.2, 11.1, 11.2, 12.5.1.2). Additionally, several animal toxicological, controlled human exposure, and epidemiologic studies did not stratify results by lifestage, but instead focused the analyses on older individuals, and can provide coherence and biological plausibility for the occurrence among this lifestage (U.S. EPA, 2019a, section 12.5.1.2).

                        Individuals with pre-existing disease may be considered at greater risk of an air pollution-related health effect than those without disease because they are likely in a compromised biological state that can vary depending on the disease and severity. With regard to cardiovascular disease, we first note that cardiovascular disease is the leading cause of death in the U.S., accounting for one in four deaths, and approximately 12% of the adult population in the U.S. has a cardiovascular disease (U.S. EPA, 2019a, section 12.3.1). Strong evidence demonstrates that there is a causal relationship between cardiovascular effects and long- and short-term exposures to PM
                        <E T="52">2.5</E>
                        . Some of the evidence supporting this conclusion is from studies of panels or cohorts with pre-existing cardiovascular disease, which provide supporting evidence but do not directly demonstrate an increased risk (U.S. EPA, 2019a, section 12.3.1). Epidemiologic evidence indicates that individuals with pre-existing cardiovascular disease may be at increased risk for PM
                        <E T="52">2.5</E>
                        -associated health effects compared to those without pre-existing cardiovascular disease. While the evidence does not consistently support increased risk for all pre-existing cardiovascular diseases, there is evidence that certain pre-existing cardiovascular diseases (
                        <E T="03">e.g.,</E>
                         hypertension) may be a factor that increases PM
                        <E T="52">2.5</E>
                        -related risk. Furthermore, there is strong evidence supporting a causal relationship for long- and short-term PM
                        <E T="52">2.5</E>
                         exposure and cardiovascular effects, particularly for IHD (U.S. EPA, 2019a, chapter 6, section 12.3.1).

                        With regard to respiratory disease, we first note that the most chronic respiratory diseases in the U.S. are asthma and COPD. Asthma affects a substantial fraction of the U.S. population and is the leading chronic disease among children. COPD primarily affects older adults and contributes to compromised respiratory function and underlying pulmonary inflammation. The body of evidence indicates that individuals with pre-existing respiratory diseases, particularly asthma and COPD, may be at increased risk for PM
                        <E T="52">2.5</E>
                        -related health effects compared to those without pre-existing respiratory diseases (U.S. EPA, 2019a, section 12.3.5). There is strong evidence indicating PM
                        <E T="52">2.5</E>
                        -associated respiratory effects among those with asthma, which forms the primary evidence base for the likely to be causal relationship between short-term exposures to PM
                        <E T="52">2.5</E>
                         and respiratory health effects (U.S. EPA, 2019a, section 12.3.5). For asthma, epidemiologic evidence demonstrates associations between short-term PM
                        <E T="52">2.5</E>
                         exposures and respiratory effects, particularly evidence for asthma exacerbation, and controlled human exposure and animal toxicological studies demonstrate support for the biological plausibility for asthma exacerbation with PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2019a, section 12.3.5.1). For COPD, epidemiologic studies report positive associations between short-term PM
                        <E T="52">2.5</E>
                         exposures and hospital admissions and emergency department visits for COPD, with supporting evidence from panel studies demonstration COPD exacerbation. Epidemiologic evidence is supported by some experimental evidence of COPD-related effects, which provides support for the biological plausibility for COPD in response to PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2019a, section 12.3.5.2).

                        -related health risk, as assessed in the 2019 ISA and with even more evidence available since the literature cutoff date for the 2019 ISA and evaluated in the ISA Supplement. There is strong evidence demonstrating that Black and Hispanic populations, in particular, have higher PM

                         exposures, in comparison to non-Hispanic White populations. There is also consistent evidence across multiple studies that demonstrate increased risk of PM

                        -related health effects, with the strongest evidence for health risk disparities for mortality (U.S. EPA, 2019a, section 12.5.4). There is also evidence of health risk disparities for both Hispanic and non-Hispanic Black populations compared to non-Hispanic White populations for cause-specific mortality and incident hypertension (U.S. EPA, 2022a, section 3.3.3.2).

                        Socioeconomic status (SES) is a composite measure that includes metrics such as income, occupation, or education, and can play a role in access to healthy environments as well as access to healthcare. SES may be a factor that contributes to differential risk from PM

                        -related health outcomes. There is some evidence that supports associations larger in magnitude between mortality and long-term PM
                        <E T="52">2.5</E>
                         exposures for those with low income or living in lower income areas compared to those with higher income or living in higher income neighborhoods (U.S. EPA, 2019a, section 12.5.3; U.S. EPA, 2022a, section 3.3.3.1.1). Additionally, evidence supports conclusions that lower SES is associated with cause-specific mortality and certain health endpoints (

                         HI and CHF), but less so for all-cause or total (non-accidental) mortality (U.S. EPA, 2022a, section 3.3.3.1).

                        The magnitude and characterization of a public health impact is dependent upon the size and characteristics of the populations affected, as well as the type or severity of the effects. As summarized above, lifestage (children and older adults), race/ethnicity and SES are factors that increase the risk of PM
                        <E T="52">2.5</E>
                        -related health effects. The American Community Survey (ACS) for 2019 estimates that approximately 22% and 16% of the U.S. population are children (age&lt;18) and older adults (age 65+), respectively. For all ages, non-Hispanic Black and Hispanic populations comprise approximately 12% and 18% of the overall U.S. population in 2019. Currently available information that helps to characterize key features of these population is included in the 2022 PA (U.S. EPA, 2022b, Table 3-2).

                        -related health effects. Currently available information that helps to characterize key features of populations with cardiovascular or respiratory diseases or conditions is included in the 2022 PA (U.S. EPA, 2022b, Table 3-3). The National Center for Health Statistics data for 2018 indicate that, for adult populations, older adults (

                         those 64 years and younger). For respiratory diseases, older adults also have a higher prevalence of emphysema than younger adults, and adults 44 years or older have a higher prevalence of chronic bronchitis. However, the prevalence for asthma is generally similar across all adult age groups.

                    <P>With respect to race, American Indians or Alaskan Native populations have the highest prevalence of all heart disease and coronary heart disease, while Black populations have the highest prevalence of hypertension and stroke. Hypertension has the highest prevalence across all racial groups compared to other cardiovascular diseases or conditions, ranging from approximately 22% to 32% of each racial group. Overall, the prevalence of cardiovascular diseases or conditions is lowest for Asians compared to Whites, Blacks, and American Indians or Alaskan Natives. Asthma prevalence is highest among Black and American Indian or Alaska Native populations, while the prevalence of chronic bronchitis and emphysema is generally similar across racial groups. Overall, the prevalence of respiratory diseases is lowest for Asians compared to Whites, Blacks, and American Indians or Alaskan Natives.

                             As described in more detail in section 5 of the Preamble to the ISAs, judgments regarding causality take into consideration a number of aspects when evaluating the available scientific evidence (U.S. EPA, 2015, Table I). In reaching conclusions regarding causality, “evidence is evaluated for major outcome categories or groups of related endpoints (
                            <E T="03">e.g.,</E>
                             respiratory effects, vegetation growth), integrating evidence from across disciplines, and evaluating the coherence of evidence across a spectrum of related endpoints” (U.S. EPA, 2015, p. 24). Furthermore, “[i]n drawing judgments regarding causality for the criteria air pollutants, the ISA focuses on evidence of effects in the range of relevant pollutant exposures or doses and not on determination of causality at any dose. Emphasis is placed on evidence of effects at doses (
                            <E T="03">e.g.,</E>
                             blood Pb concentration) or exposures (
                            <E T="03">e.g.,</E>
                             air concentrations) that are relevant to, or somewhat above, those currently experienced by the population. The extent to which studies of higher concentrations are considered varies by pollutant and major outcome category, but generally includes those with doses or exposures in the range of one to two orders of magnitude above current or ambient conditions to account for intra-species variability and toxicokinetic or toxicodynamic differences between experimental animals and humans. Studies that use higher doses or exposures may also be considered to the extent that they provide useful information to inform understanding of mode of action, inter-species differences, or factors that may increase risk of effects for a population and if biological mechanisms have not been demonstrated to differ based on exposure concentration. Thus, a causality determination is based on weight-of-evidence evaluation for health or welfare effects, focusing on the evidence from exposures or doses generally ranging from recent ambient concentrations to one or two orders of magnitude above recent ambient concentrations” (U.S. EPA, 2015, p. 24).

                        of PM exposures: controlled human exposure and animal toxicological studies. In such studies, investigators expose human volunteers or laboratory animals, respectively, to known concentrations of air pollutants under carefully regulated environmental conditions and activity levels. Thus, controlled human exposure and animal toxicological studies can provide information on the health effects of experimentally administered pollutant exposures under highly controlled laboratory conditions (U.S. EPA, 2015, p. 11).

                         exposures lasting from less than one hour up to five hours can impact cardiovascular function,

                         and the most consistent evidence from these studies is for impaired vascular function (U.S. EPA, 2019a, section 6.1.13.2). In addition, although less consistent, the 2019 ISA notes that studies examining PM
                        <E T="52">2.5</E>
                         exposures also provide evidence for increased blood pressure (U.S. EPA, 2019a, section 6.1.6.3), conduction abnormalities/arrhythmia (U.S. EPA, 2019a, section 6.1.4.3), changes in heart rate variability (U.S. EPA, 2019a, section 6.1.10.2), changes in hemostasis that could promote clot formation (U.S. EPA, 2019a, section 6.1.12.2), and increases in inflammatory cells and markers (U.S. EPA, 2019a, section 6.1.11.2). The 2019 ISA concludes that, when taken as a whole, controlled human exposure studies demonstrate that short-term exposure to PM
                        <E T="52">2.5</E>
                         may impact cardiovascular function in ways that could lead to more serious outcomes (U.S. EPA, 2019a, section 6.1.16). Thus, such studies can provide insight into the potential for specific PM
                        <E T="52">2.5</E>
                         exposures to result in physiological changes that could increase the risk of more serious effects. Table 3-4 in the 2022 PA summarizes information from the 2019 ISA and 2022 ISA supplement on available controlled human exposure studies that evaluate effects on markers of cardiovascular function following exposure to PM
                        <E T="52">2.5</E>
                         (U.S. EPA, 2022b). Most of the controlled human exposure studies in Table 3-4 of the 2022 PA have evaluated average PM
                        <E T="52">2.5</E>
                         concentrations at or above about 100 µg/m
                        <SU>3</SU>
                        , with exposure durations typically up to about two hours. Statistically significant effects on one or more indicators of cardiovascular function are often, though not always, reported following 2-hour exposures to average PM
                        <E T="52">2.5</E>
                         concentrations at and above about 120 µg/m
                        <SU>3</SU>
                        , with less consistent evidence for effects following exposures to concentrations lower than 120 µg/m
                        <SU>3</SU>
                        . Impaired vascular function, the effect identified in the 2019 ISA as the most consistent across studies (U.S. EPA, 2019a, section 6.1.13.2) is shown following 2-hour exposures to PM
                        <E T="52">2.5</E>
                         concentrations at and above 149 µg/m
                        <SU>3</SU>
                        . Mixed results are reported in the studies that evaluated longer exposure durations (
                        <E T="03">i.e.,</E>
                         longer than 2 hours) and lower (

                         concentrations (U.S. EPA, 2022b, section 3.3.3.1). For example, significant effects for some outcomes were reported following 5-hour exposures to 24 µg/m
                        <SU>3</SU>
                         in Hemmingsen et al. (2015b), but not for other outcomes following 5-hour exposures to 24 µg/m

                         in Bräuner et al. (2008). Additionally, Wyatt et al. (2020) found significant effects for some cardiovascular (

                         systematic inflammation markers, cardiac repolarization, and decreased pulmonary function) effects following 4-hour exposures to 37.8 µg/m
                        <SU>3</SU>
                         in healthy young participants (18-35 years, n=21) who were subject to intermittent moderate exercise. The higher ventilation rate and longer exposure duration in this study compared to most controlled human exposure studies is roughly equivalent to a 2-hour exposure of 75-100 µg/m
                        <SU>3</SU>
                         of PM
                        <E T="52">2.5</E>
                        . Therefore, dosimetric considerations may explain the observed changes in inflammation in young healthy individuals. Though this study provides evidence of some effects at lower PM
                        <E T="52">2.5</E>
                         concentrations, overall, there is inconsistent evidence for inflammation in other controlled human exposure studies evaluated in the 2019 ISA (U.S. EPA, 2019a, sections 5.1.7., 5.1.2.3.3, and 6.1.11.2.1; U.S. EPA, 2022a, section 3.3.1).

                             In contrast, controlled human exposure studies provide little evidence for respiratory effects following short-term PM

                             exposures (U.S. EPA, 2019a, section 5.1, Table 5-18). Therefore, this section focuses on cardiovascular effects evaluated in controlled human exposure studies of PM
                            <E T="52">2.5</E>
                             exposure.

                    <P>
                        While controlled human exposure studies are important in establishing biological plausibility, it is unclear how the results from these studies alone and the importance of the effects observed in these studies, should be interpreted with respect to adversity to public health. More specifically, impaired vascular function can signal an intermediate effect along the potential biological pathways for cardiovascular effects following short-term exposure to PM
                        <E T="52">2.5</E>
                         and show a role for exposure to PM
                        <E T="52">2.5</E>
                         leading to potential worsening of IHD and heart failure followed potentially by ED visits, hospital admissions, or mortality (U.S. EPA, 2019a, section 6.1 and Figure 6-1). However, just observing the occurrence of impaired vascular function alone does not clearly suggest an adverse health outcome. Additionally, associated judgments regarding adversity or health significance of measurable physiological responses to air pollutants have been informed by guidance, criteria or interpretative statements developed within the public health community, including the American Thoracic Society (ATS) and the European Respiratory Society (ERS), which cooperatively updated the ATS 2000 statement 
                        <E T="03">What Constitutes an Adverse Health Effect of Air Pollution</E>
                         (ATS, 2000) with new scientific findings, including the evidence related to air pollution and the cardiovascular system (Thurston et al., 2017).
                        <SU>64</SU>
                        <FTREF/>
                         With regard to vascular function, the ATS/ERS statement considers the adversity of both chronic and acute reductions in endothelial function. While the ATS/ERS statement concluded that chronic endothelial and vascular dysfunction can be judged to be a biomarker of an adverse health effect from air pollution, they also conclude that “the health relevance of acute reductions in endothelial function induced by air pollution is less certain” (Thurston et al., 2017). This is particularly informative to our consideration of the controlled human exposure studies which are short-term in nature (
                        <E T="03">i.e.,</E>
                         generally ranging from 2- to 5-hours), including those studies that are conducted at near-ambient PM
                        <E T="52">2.5</E>
                         concentrations.

                             The ATS/ERS described its 2017 statement as one “intended to provide guidance to policymakers, clinicians and public health professionals, as well as others who interpret the scientific evidence on the health effects of air pollution for risk management purposes” and further notes that “considerations as to what constitutes an adverse health effect, in order to provide guidance to researchers and policymakers when new health effects markers or health outcome associations might be reported in future.” The most recent policy statement by the ATS, which once again broadens its discussion of effects, responses and biomarkers to reflect the expansion of scientific research in these areas, reiterates that concept, conveying that it does not offer “strict rules or numerical criteria, but rather proposes considerations to be weighed in setting boundaries between adverse and nonadverse health effects,” providing a general framework for interpreting evidence that proposes a “set of considerations that can be applied in forming judgments” for this context (Thurston et al., 2017).

                        The 2022 PA also notes that it is important to recognize that controlled human exposure studies include a small number of individuals compared to epidemiologic studies. Additionally, these studies tend to include generally healthy adult individuals, who are at a lower risk of experiencing health effects. 
                        <PRTPAGE P="16238"/>
                        These studies, therefore, often do not include children, older adults, or individuals with pre-existing conditions. As such, these studies are somewhat limited in their ability to inform at what concentrations effects may be elicited in at-risk populations.

                         concentrations at such locations are likely to exceed the 2-hour exposure concentrations in the controlled human exposure studies at which statistically significant effects are reported in multiple studies for one or more indicators of cardiovascular function. At sites meeting the current primary PM

Most of the sites measuring these very high concentrations are in the northwestern U.S. and California (U.S. EPA, 2022b, Appendix A, Figure A-1), where wildfires have been relatively common in recent years. When the typical fire season is excluded from the analysis, the extreme upper end of the distribution is reduced (

                        As with controlled human exposure studies, most animal toxicological studies evaluated in the 2019 ISA have examined effects following exposure to PM
                        <E T="52">2.5</E>
                         well above the concentrations likely to be allowed by the current PM

                         (Cangerana Pereira et al., 2011). These two studies report serious effects following long-term exposures to PM

                         exposures and doses that cause those effects to human populations, animal toxicological studies are of limited utility in informing decisions on the public health protection provided by the current or alternative primary PM

                         standards. Therefore, the animal toxicological studies are most useful in providing further evidence to support the biological mechanisms and plausibility of various adverse effects.

                        As summarized in section II.A.2.a above, epidemiologic studies examining associations between daily or annual average PM
                        <E T="52">2.5</E>
                         exposures and mortality or morbidity represent a large part of the evidence base supporting several of the 2019 ISA's “causal” and “likely to be causal” determinations. The 2022 PA considers the ambient PM

                         concentrations present in areas where epidemiologic studies have evaluated associations with mortality or morbidity, and what such concentrations may indicate regarding the adequacy of the primary PM

                        <E T="52">2.5</E>
                         standards is complicated by the fact that such studies evaluate associations between distributions of ambient PM

                         concentrations evaluated, and epidemiologic studies conducted to date do not identify a population-level threshold below which it can be concluded with confidence that PM

                         air quality distributions over which epidemiologic studies support health effect associations (U.S. EPA, 2022b, section 3.3.3.2). In the absence of discernible thresholds, the 2022 PA considers the study-reported ambient PM
                        <E T="52">2.5</E>
                         concentrations reflecting estimated exposure with a focus around the middle portion of the PM

                         air quality distribution, where the bulk of the observed data reside and which provides the strongest support for reported health effect associations. The section below, as well as in more detail in section II.B.3.b.i of the proposal (88 FR 5594, January 27, 2023), describes the consideration of the key epidemiologic studies and observations from these studies, as evaluated in the 2022 PA (U.S. EPA, 2022b, section 3.3.3.2).

                    <P>
                        As an initial matter, in considering the PM
                        <E T="52">2.5</E>
                         air quality distributions associated with mortality or morbidity in the key epidemiologic studies, the 2022 PA recognizes that in previous reviews, the decision framework used to judge adequacy of the existing PM
                        <E T="52">2.5</E>
                         standards, and what levels of any potential alternative standards should be considered, placed significant weight on epidemiologic studies that assessed associations between PM
                        <E T="52">2.5</E>
                         exposure and health outcomes that were most strongly supported by the body of scientific evidence. In doing so, the decision framework recognized that while there is no specific point in the air quality distribution of any 
                        <PRTPAGE P="16239"/>
                        epidemiologic study that represents a “bright line” at and above which effects have been observed and below which effects have not been observed, there is significantly greater confidence in the magnitude and significance of observed associations for the part of the air quality distribution corresponding to where the bulk of the health events in each study have been observed, generally at or around the mean concentration. This is the case both for studies of daily PM
                        <E T="52">2.5</E>
                         exposures and for studies of annual average PM
                        <E T="52">2.5</E>
                         exposures (U.S. EPA, 2022b, section 3.3.3.2.1).
                    </P>
                    <P>
                        As discussed further in the 2022 PA, studies of daily PM
                        <E T="52">2.5</E>
                         exposures examine associations between day-to-day variation in PM
                        <E T="52">2.5</E>
                         concentrations and health outcomes, often over several years (U.S. EPA, 2022b, section 3.3.3.2.1). While there can be considerable variability in daily exposures over a multi-year study period, most of the estimated exposures reflect days with ambient PM
                        <E T="52">2.5</E>
                         concentrations around the middle of the air quality distributions examined (
                        <E T="03">i.e.,</E>
                         “typical” days rather than days with extremely high or extremely low concentrations). Similarly, for studies of annual PM
                        <E T="52">2.5</E>
                         exposures, most of the health events occur at estimated exposures that reflect annual average PM
                        <E T="52">2.5</E>
                         concentrations around the middle of the air quality distributions examined. In both cases, epidemiologic studies provide the strongest support for reported health effect associations for this middle portion of the PM
                        <E T="52">2.5</E>
                         air quality distribution, which corresponds to the bulk of the underlying data, rather than the extreme upper or lower ends of the distribution. Consistent with this, as noted in the 2022 PA (U.S. EPA, 2022b, section 3.3.1.1), several epidemiologic studies report that associations persist in analyses that exclude the upper portions of the distributions of estimated PM
                        <E T="52">2.5</E>
                         exposures, indicating that “peak” PM
                        <E T="52">2.5</E>
                         exposures are not disproportionately responsible for reported health effect associations.

                    <P>
                        Thus, in considering PM
                        <E T="52">2.5</E>
                         air quality data from epidemiologic studies, consistent with approaches in the 2012 and 2020 reviews (78 FR 3161, January 15, 2013; U.S. EPA, 2011, sections 2.1.3 and 2.3.4.1; 85 FR 82716-82717, December 18, 2020; U.S. EPA, 2020b, sections 3.1.2 and 3.2.3), the 2022 PA evaluates study-reported means (or medians) of daily and annual average PM
                        <E T="52">2.5</E>
                         concentrations as indicators for the middle portions of the air quality distributions, over which studies generally provide strong support for reported associations and for which confidence in the magnitude and significance of associations observed in the epidemiologic studies is greatest (78 FR 3101, January 15, 2013). In addition to the overall study means, the 2022 PA also focuses on concentrations somewhat below the means (
                        <E T="03">e.g.,</E>
                         25th and 10th percentiles), when such information is available from the epidemiologic studies, which again is consistent with approaches used in previous reviews. In so doing, the 2022 PA notes, as in previous reviews, that a relatively small portion of the health events are observed in the lower part of the air quality distribution and confidence in the magnitude and significance of the associations begins to decrease in the lower part of the air quality distribution. Furthermore, consistent with past reviews, there is no single percentile value within a given air quality distribution that is most appropriate or “correct” to use to characterize where our confidence in associations becomes appreciably lower. However, and as detailed further in the 2022 PA, the range from the 25th to 10th percentiles is a reasonable range to consider as a region where there is appreciably less confidence in the associations observed in epidemiologic studies compared to the means (U.S. EPA, 2022b, p. 3-69).

                             As detailed in the 2011 PA, we note the interrelatedness of the distributional statistics and a range of one standard deviation around the mean which represents approximately 68% of normally distributed data, and in that one standard deviation below the mean falls between the 25th and 10th percentiles (U.S. EPA, 2011, p. 2-71; U.S. EPA, 2005, p. 5-22).

                    </FTNT>
                    <P>
                        In evaluating the overall study-reported means, and concentrations somewhat below the means from epidemiologic studies, the 2022 PA focuses on the form, averaging time and level of the current primary annual PM
                        <E T="52">2.5</E>
                         standard. Consistent with the approaches used in the 2012 and 2020 reviews (78 FR 3161-3162, January 15, 2013; 85 FR 82716-82717, December 18, 2020), the annual standard has been utilized as the primary means of providing public health protection against the bulk of the distribution of short- and long-term PM
                        <E T="52">2.5</E>
                         exposures. Thus, the evaluation of the study-reported mean concentrations from key epidemiologic studies lends itself best to evaluating the adequacy of the annual PM
                        <E T="52">2.5</E>
                         standard (rather than the 24-hour standard with its 98th percentile form). This is true for the study-reported means from both long-term and short-term exposure epidemiologic studies, recognizing that the overall mean PM
                        <E T="52">2.5</E>
                         concentrations reported in studies of short-term (24-hour) exposures reflect averages across the study population and over the years of the study. Thus, mean concentrations from short-term exposure studies reflect long-term averages of 24-hour PM
                        <E T="52">2.5</E>
                         exposure estimates. In this manner, the examination of study-reported means in key epidemiologic studies in the 2022 PA aims to evaluate the protection provided by the annual PM
                        <E T="52">2.5</E>
                         standard against the exposures where confidence is greatest for associations with mortality and morbidity. In addition, the protection provided by the annual standard is evaluated in conjunction with that provided by the 24-hour standard, with its 98th percentile form, which aims to provide supplemental protection against the short-term exposures to peak PM
                        <E T="52">2.5</E>
                         concentrations that can occur in areas with strong contributions from local or seasonal sources, even when overall ambient mean PM
                        <E T="52">2.5</E>
                         concentrations in an area remain relatively low.
                    </P>
                    <P>
                        In focusing on the annual standard, and in evaluating the range of study-reported exposure concentrations for which the strongest support for adverse health effects exists, the 2022 PA examines exposure concentrations in key epidemiologic studies to determine whether the current primary annual PM
                        <E T="52">2.5</E>
                         standard provides adequate protection against these exposure concentrations. This means, as in past reviews, application of a decision framework based on assessing means reported in key epidemiologic studies must also consider how the study means were computed and how these values compare to the annual standard metric (including the level, averaging time and form) and the use of the monitor with the highest PM
                        <E T="52">2.5</E>
                         design value in an area for compliance. In the 2012 review, it was recognized that the key epidemiologic studies computed the study mean using an average across monitor-based PM
                        <E T="52">2.5</E>
                         concentrations. As such, the Agency noted that this decision framework applied an approach of using maximum monitor concentrations to determine compliance with the standard, while selecting the standard level based on consideration of composite monitor concentrations. Further, the Agency included analyses (Hassett-Sipple et al., 2010; Frank, 2012) that examined the differences in these two metrics (
                        <E T="03">i.e.,</E>
                         maximum monitor concentrations and composite monitor concentrations) across the U.S. and in areas included in the key epidemiologic studies and found that the maximum design value in an area was generally higher than the monitor average across that area, with the difference varying 
                        <PRTPAGE P="16240"/>
                        based on location and concentration. This information was taken into account in the Administrator's final decision in selecting a level for the primary annual PM

                         standard the 2012 review and discussed more specifically in her considerations on adequate margin of safety.

                    <P>
                        Consistent with the approach taken in 2012, in assessing how the overall mean (or median) PM
                        <E T="52">2.5</E>
                         concentrations reported in key epidemiologic studies can inform conclusions on the primary annual PM
                        <E T="52">2.5</E>
                         standard, the 2022 PA notes that the relationship between mean PM
                        <E T="52">2.5</E>
                         concentrations and the area design value continues to be an important consideration in evaluating the adequacy of the current or potential alternative annual PM
                        <E T="52">2.5</E>
                         standard levels in this reconsideration. In a given area, the area design value is based on the monitor in an area with the highest PM
                        <E T="52">2.5</E>
                         concentrations and is used to determine compliance with the standard. The highest PM
                        <E T="52">2.5</E>
                         concentrations spatially distributed in the area would generally occur at or near the area design value monitor and the distribution of PM
                        <E T="52">2.5</E>
                         concentrations would generally be lower in other locations and at monitors in that area. As such, when an area is meeting a specific annual standard level, the annual average exposures in that area are expected to be at concentrations lower than that level and the average of the annual average exposures across that area are expected (
                        <E T="03">i.e.,</E>

                        Another important consideration is that there are a substantial number of different types of epidemiologic studies available since the 2012 review, included in both the 2019 ISA and the ISA Supplement, that make understanding the relationship between the mean PM
                        <E T="52">2.5</E>
                         concentrations and the area design value even more important (U.S. EPA, 2019a; U.S. EPA, 2022a). While the key epidemiologic studies in the 2012 review were all monitor-based studies, the newer studies include hybrid modeling approaches, which have emerged in the epidemiologic literature as an alternative to approaches that only use ground-based monitors to estimate exposure. As assessed in the 2019 ISA and ISA Supplement, a substantial number of epidemiologic studies used hybrid model-based methods in evaluating associations between PM
                        <E T="52">2.5</E>
                         exposure and health effects (U.S. EPA, 2019a; U.S. EPA, 2022a). Hybrid model-based studies employ various fusion techniques that combine ground-based monitored data with air quality modeled estimates and/or information from satellites to estimate PM
                        <E T="52">2.5</E>
                         exposures.
                        <SU>68</SU>
                        <FTREF/>
                         Additionally, hybrid modeling approaches tend to broaden the areas captured in the exposure assessment, and in so doing, tend to report lower mean PM
                        <E T="52">2.5</E>
                         concentrations than monitor-based approaches because they include more suburban and rural areas where concentrations are lower. While these studies provide a broader estimation of PM
                        <E T="52">2.5</E>
                         exposures compared to monitor-based studies (
                        <E T="03">i.e.,</E>
                         PM
                        <E T="52">2.5</E>
                         concentrations are estimated in areas without monitors), the hybrid modeling approaches result in study-reported means that are more difficult to relate to the annual standard metric and to the use of maximum monitor design values to assess compliance. In addition, and to further complicate the comparison, when looking across these studies, variations exist in how exposure is estimated between such studies, which in turn affects how the study means are calculated. Two important variations across studies include: (1) Variability in spatial scale used (
                        <E T="03">i.e.,</E>
                         averages computed across the nation (or large portions of the country) versus a focus on only CBSAs) and (2) variability in exposure assignment methods (
                        <E T="03">i.e.,</E>
                         averaging across all grid cells [non-population weighting], averaging across a scaled-up area like a ZIP code [aspects of population weighting applied], and/or applying population weighting). To elaborate further on the variability in exposure assignment methods, studies that use hybrid modeling approaches can estimate PM
                        <E T="52">2.5</E>
                         concentrations at different spatial resolutions, including at 1 km x 1 km grid cells, at 12 km x 12 km grid cells, or at the census tract level. Mean reported PM
                        <E T="52">2.5</E>
                         concentrations can then be estimated either by averaging up to a larger spatial resolution that corresponds to the spatial resolution for which health data exists (
                        <E T="03">e.g.,</E>
                         ZIP code level) and therefore apply aspects of population weighting. These values are then averaged across all study locations at the larger spatial resolution (
                        <E T="03">e.g.,</E>
                         averaged across all ZIP codes in the study) over the study period, resulting in the study-reported mean 24-hour average or average annual PM
                        <E T="52">2.5</E>
                         concentration. Other studies that use hybrid modeling methods to estimate PM
                        <E T="52">2.5</E>
                         concentrations may use each grid cell to calculate the study-reported mean 24-hour average or average annual PM
                        <E T="52">2.5</E>
                         concentration. As such, these types of studies do not apply population weighting in their mean concentrations. In studies that use each grid cell to report a mean PM
                        <E T="52">2.5</E>
                         concentration and do not apply aspects of population weighting, the study mean may not reflect the exposure concentrations used in the epidemiologic study to assess the reported association. The impact of the differences in methods is an important consideration when comparing mean concentrations across studies (U.S. EPA, 2022b, section 3.3.3.2.1). Thus, the 2022 PA also considers the methods used to estimate PM

                        Given the emergence of the hybrid model-based epidemiologic studies since the 2012 review, the 2022 PA explores the relationship between the approaches used in these studies to estimate PM
                        <E T="52">2.5</E>

The 2022 PA further seeks to understand how the approaches and resulting mean concentrations compare across studies, as well as what the resulting mean values represent relative to the annual standard. In so doing, the 2022 PA presents analyses that compare the area annual design values, composite monitor PM

                         design values in U.S. CBSAs, maximum annual PM
                        <E T="52">2.5</E>
                         design values were approximately 10% to 20% higher than annual average composite monitor concentrations (
                        <E T="03">i.e.,</E>
                         averaged across multiple monitors in the same CBSA) (sections I.D.5.a above and U.S. EPA, 2022b, section 2.3.3.1, Figure 2-28 and Table 2-3). The difference between the maximum annual design value and average concentration in an area can be smaller or larger than this range (10-20%), depending on a variety of factors such as the number of monitors, monitor siting characteristics, the distribution of ambient PM
                        <E T="52">2.5</E>
                         concentrations, and how the average concentrations are calculated (
                        <E T="03">i.e.,</E>
                         averaged across monitors versus across modeled grid cells). Results of this analysis suggest that there will be a distribution of concentrations across an area and the maximum annual average monitored concentration in an area (at the design value monitor, used for compliance with the standard), will generally be 10-20% higher than the average PM
                        <E T="52">2.5</E>
                         concentration across the other monitors in the area. Thus, in considering how the annual standard levels would relate to the study-reported means from key monitor-based epidemiologic studies, the 2022 PA generally concludes that an annual standard level that is no more than 10-20% higher than monitor-based study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations would generally maintain air quality exposures to be below those associated with the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, exposures for which the strongest support for adverse health effects occurring is available.

                        The 2022 PA also evaluates data from two hybrid modeling approaches (DI2019 and HA2020) that have been used in several recent epidemiologic studies (U.S. EPA, 2022b, section 2.3.3.2.4).
                        <SU>71</SU>
                        <FTREF/>
                         The analysis shows that the means differ when PM
                        <E T="52">2.5</E>
                         concentrations are estimated in urban areas only (CBSAs) versus when the averages were calculated with all or most grid cells nationwide, likely because areas included outside of CBSAs tend to be more rural and have lower estimated PM
                        <E T="52">2.5</E>
                         concentrations. The 2022 PA recognizes the importance of this variability in the means since the study areas included in the calculation of the mean, and more specifically whether a study is focused on nationwide, regional, or urban areas, will affect the calculation of the study mean based on how many rural areas, with lower estimated PM
                        <E T="52">2.5</E>
                         concentrations, are included in the study area. While the determination of what spatial scale to use to estimate PM
                        <E T="52">2.5</E>
                         concentrations does not inherently affect the quality of the epidemiologic study, the spatial scale can influence the calculated reported long-term mean concentration across the study area and period. The results of the analysis show that, regardless of the hybrid modeling approach assessed, the annual average PM
                        <E T="52">2.5</E>
                         concentrations in CBSA-only analyses are 4-8% higher than for nationwide analyses, likely as a result of higher PM
                        <E T="52">2.5</E>
                         concentrations in more densely populated areas, and exclusion of more rural areas (U.S. EPA, 2022b, Table 2-4).

                        Based on these results, and similar to conclusions for the monitor-based studies, the 2022 PA generally concludes that study-reported mean concentrations in the studies that employ hybrid modeling approaches and calculate a population-weighted mean are associated with air quality conditions that would be achieved by meeting annual standard levels that are 15-18% higher than study-reported means. Therefore, an annual standard level that is no more than 15-18% higher than the study-reported means would generally maintain air quality exposures to be below those associated with the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, exposures for which we have the strongest support for adverse health effects occurring. For the studies that utilize hybrid modeling approaches but do not incorporate population weighting in calculating the mean, the annual design values associated with these air quality conditions are expected to be much higher (
                        <E T="03">i.e.,</E>
                         40-50% higher) and this larger difference makes it more difficult to consider how these studies can be used to determine the adequacy of the protection afforded by the current or potential alternative annual standards. Additionally, as noted above in studies that utilize hybrid modeling approaches and that do not incorporate population weighting in calculating the mean (
                        <E T="03">e.g.,</E>
                         use each grid cell to calculate a mean PM

                         concentration), the study mean does not reflect the exposure concentrations used in the epidemiologic study to assess the reported association.

                    <P>
                        The 2022 PA notes that while these analyses can be useful to informing the understanding of the relationship between study-reported mean concentrations and the level of the annual standard, some limitations of this analysis must be recognized (U.S. EPA, 2022a, section 3.3.3.2.1). First, the comparisons used only two hybrid modeling approaches. Although these two hybrid modeling surfaces have been used in a number of recent epidemiologic studies, they represent just two of the many hybrid modeling approaches that have been used in epidemiologic studies to estimate PM
                        <E T="52">2.5</E>
                         concentrations. These methods continue to evolve, with further development and improvement to prediction models that estimate PM
                        <E T="52">2.5</E>
                         concentrations in epidemiologic studies. In addition to differences in hybrid modeling approaches, epidemiologic studies also use different methods to assign a population weighted average PM
                        <E T="52">2.5</E>
                         concentration to their study population, and the assessment presented in the

                    <P>
                        Additionally, while some of these epidemiologic studies also provide information on the broader distributions of exposure estimates and/or health events and the PM
                        <E T="52">2.5</E>
                         concentrations corresponding to the lower percentiles of those data (
                        <E T="03">e.g.,</E>
                         25th and/or 10th), the air quality analysis in the 2022 PA focuses on mean PM
                        <E T="52">2.5</E>
                         concentrations and a similar comparison for lower percentiles of data was not assessed. Therefore, any direct comparison of study-reported PM
                        <E T="52">2.5</E>
                         concentrations corresponding to lower percentiles and annual design values is more uncertain than such comparisons with the mean. Finally, air quality analysis presented in the 2022 PA and detailed above in section I.D.5 included two hybrid modeling-based approaches that used U.S.-based air quality information for estimating PM
                        <E T="52">2.5</E>
                         concentrations. As such, the analyses are most relevant to interpreting the study-reported mean concentrations from U.S. epidemiologic studies and do not provide additional information about how the mean exposures concentrations reported in epidemiologic studies in other countries would compare to annual design values observed in the U.S. In addition, while information from Canadian studies can be useful in assessing the adequacy of the annual standard, differences in the exposure environments and population characteristics between the U.S. and other countries can affect the study-reported mean value and its relationship with the annual standard level. Sources and pollutant mixtures, as well as PM
                        <E T="52">2.5</E>
                         concentration gradients, may be different between countries, and the exposure environments in other countries may differ from those observed in the U.S. Furthermore, differences in population characteristics and population densities can also make it challenging to directly compare studies from countries outside of the U.S. to a design value in the U.S.

                        As with the experimental studies discussed above, the 2022 PA focuses on epidemiologic studies assessed in the 2019 ISA and ISA Supplement that have the potential to be most informative in reaching decisions on the adequacy of the primary PM
                        <E T="52">2.5</E>
                         standards. The 2022 PA focuses on epidemiologic studies that provide strong support for “causal” or “likely to be causal” relationships with PM
                        <E T="52">2.5</E>
                         exposures in the 2019 ISA. Further, the 2022 PA also focuses on the health effect associations that are determined in the 2019 ISA and ISA Supplement to be consistent across studies, coherent with the broader body of evidence (
                        <E T="03">e.g.,</E>
                         including animal and controlled human exposure studies), and robust to potential confounding by co-occurring pollutants and other factors.

                        <FTREF/>
                         In particular the 2022 PA considers the U.S. and Canadian epidemiologic studies to be more useful for reaching conclusions on the current standards than studies conducted in other countries, given that the results of the U.S. and Canadian studies are more directly applicable for quantitative considerations, whereas studies conducted in other countries reflect different populations, exposure characteristics, and air pollution mixtures. Additionally, epidemiologic studies outside of the U.S. and Canada generally reflect higher PM
                        <E T="52">2.5</E>
                         concentrations in ambient air than are currently found in the U.S., and are less relevant to informing questions about adequacy of the current standards.
                        <SU>74</SU>
                        <FTREF/>
                         However, and as noted above, the 2022 PA also recognizes that while information from Canadian studies can be useful in assessing the adequacy of the annual standard, there are still important differences between the exposure environments in the U.S. and Canada and interpreting the data (
                        <E T="03">e.g.,</E>
                         mean concentrations) from the Canadian studies in the context of a U.S.-based standard may present challenges in directly and quantitatively informing questions regarding the adequacy of the current or potential alternative the levels of the annual standard. Lastly, the 2022 PA emphasizes multicity/multistate studies that examine health effect associations, as such studies are more encompassing of the diverse atmospheric conditions and population demographics in the U.S. than studies that focus on a single city or State. Figures 3-4 through 3-7 in the 2022 PA summarize the study details for the key U.S. and Canadian epidemiologic studies (U.S. EPA, 2022b, section 3.3.3.2.1).

                             As described in the Preamble to the ISAs (U.S. EPA, 2015), “the U.S. EPA emphasizes the importance of examining the pattern of results across various studies and does not focus solely on statistical significance or the magnitude of the direction of the association as criteria of study reliability. Statistical significance is influenced by a variety of factors including, but not limited to, the size of the study, exposure and outcome measurement error, and statistical model specifications. Statistical significance may be informative; however, it is just one of the means of evaluating confidence in the observed relationship and assessing the probability of chance as an explanation. Other indicators of reliability such as the consistency and coherence of a body of studies as well as other confirming data may be used to justify reliance on the results of a body of epidemiologic studies, even if results in individual studies lack statistical significance. Traditionally, statistical significance is used to a larger extent to evaluate the findings of controlled human exposure and animal toxicological studies. Understanding that statistical inferences may result in both false positives and false negatives, consideration is given to both trends in data and reproducibility of results. Thus, in drawing judgments regarding causality, the U.S. EPA emphasizes statistically significant findings from experimental studies, but does not limit its focus or consideration to statistically significant results in epidemiologic studies.”

                             This emphasis on studies conducted in the U.S. or Canada is consistent with the approach in the 2012 and 2020 reviews of the PM NAAQS (U.S. EPA, 2011, section 2.1.3; U.S. EPA, 2020b, section 3.2.3.2.1) and with approaches taken in other NAAQS reviews. However, the importance of studies in the U.S., Canada, and other countries in informing an ISA's considerations of the weight of the evidence that informs causality determinations is recognized.

                         exposure by averaging each grid cell across the entire study area, whether that be the nation or a region of the country. These studies do not weight the estimated exposure concentrations based on population density or location of health events. As such, the study mean reported in these studies may not reflect the exposure concentrations used in the epidemiologic study to assess the reported association. As a result, these reported mean concentrations are the most different (and much lower) than the means reported in monitor-based studies. Due to the methodology employed in calculating the study-reported means and not necessarily a difference in estimates of exposure, these epidemiologic studies are expected to report some of the lowest mean values. For these studies, the reported mean PM
                        <E T="52">2.5</E>

                         40-50% higher) than the study-reported means. This larger difference between design values and study-reported mean concentrations makes it more difficult to consider how these studies can be used to determine the adequacy of the protection afforded by the current or potential alternative annual standards (U.S. EPA, 2022b, section 3.3.3.2.1).

                        Restricted analyses are studies that examine health effect associations in analyses with the highest exposures excluded, restricting analyses to daily exposures less than the 24-hour primary PM

While these studies are useful in supporting the confidence and strength of associations at lower concentrations, these studies also have inherent uncertainties and limitations, including uncertainty in how studies exclude concentrations (
                        <E T="03">e.g.,</E>
                         are they excluded at the modeled grid cell level, the ZIP code level) and in how concentrations in studies that restrict air quality data relate to design values for the annual and 24-hour standards. Further, these studies often do not report descriptive statistics (
                        <E T="03">e.g.,</E>

As such, while these studies can provide additional supporting evidence for associations at lower concentrations, the 2022 PA notes that there are also limitations in how to interpret these studies when evaluating the adequacy of the current or potential alternative standards.

Alternative methods for confounder control seek to mimic randomized experiments through the use of study design and statistical methods to more extensively account for confounders and are more robust to model misspecification. The 2022 PA presents a summary of the studies that employ alternative methods for confounder control, and employ a variety of statistical methods, which are evaluated in the 2019 ISA and ISA Supplement (U.S. EPA, 2022b, Table 3-11). These studies reported consistent results among large study populations across the U.S. and can further inform the relationship between long- and short-term PM

Some of these studies, accountability studies, provide insight on whether the implementation of environmental policies or air quality interventions result in changes/reductions in air pollution concentrations and the corresponding effect on health outcomes.

                        The 2022 PA recognizes that there are a number of uncertainties and limitations associated with the available health effects evidence. Although the epidemiologic studies clearly demonstrate associations between long- and short-term PM
                        <E T="52">2.5</E>
                         exposures and health outcomes, several uncertainties and limitations in the health effects evidence remain. Epidemiologic studies evaluating short-term PM
                        <E T="52">2.5</E>
                         exposure and health effects have reported heterogeneity in associations between cities and geographic regions within the U.S. Heterogeneity in the associations observed across epidemiologic studies may be due in part to exposure error related to measurement-related issues, the use of central fixed-site monitors to represent population exposure to PM
                        <E T="52">2.5</E>
                        , and a limited understanding of factors including exposure error related to measurement-related issues, variability in PM
                        <E T="52">2.5</E>
                         composition regionally, and factors that result in differential exposures (
                        <E T="03">e.g.,</E>
                         topography, the built environment, housing characteristics, personal activity patterns). Heterogeneity is expected when the methods or the underlying distribution of covariates vary across studies (U.S. EPA, 2019a, p. 6-221). Studies assessed in the 2019 ISA and ISA Supplement have advanced the state of exposure science by presenting innovative methodologies to estimate PM exposure, detailing new and existing measurement and modeling methods, and further informing our understanding of the influence of exposure measurement error due to exposure estimation methods on the associations between PM
                        <E T="52">2.5</E>
                         and health effects reported in epidemiologic studies (U.S. EPA, 2019a, section 1.2.2; U.S. EPA, 2022a). Data from PM
                        <E T="52">2.5</E>
                         monitors continue to be commonly used in health studies as a surrogate for PM
                        <E T="52">2.5</E>
                         exposure, and often provide a reasonable representation of exposures throughout a study area (U.S. EPA, 2019a, section 3.4.2.2; U.S. EPA, 2022a, section 3.2.2.2.2). However, an increasing number of studies employ hybrid modeling methods to estimate PM
                        <E T="52">2.5</E>
                         exposure using data from several sources, often including satellites and models, in addition to ground-based monitors. These hybrid models typically have good cross-validation, especially for PM
                        <E T="52">2.5</E>
                        , and have the potential to reduce exposure measurement error and uncertainty in the health effect estimates from epidemiologic models of long-term exposure (U.S. EPA, 2019a, section 3.5; U.S. EPA, 2022a, section 2.3.3).

                    <P>
                        While studies using hybrid modeling methods have reduced exposure measurement error and uncertainty in the health effect estimates, these studies use a variety of approaches to estimate PM
                        <E T="52">2.5</E>
                         concentrations and to assign exposure to assess the association between health outcomes and PM
                        <E T="52">2.5</E>
                         exposure. This variability in methodology has inherent limitations and uncertainties, as described in more detail in section 2.3.3.1.5 of the 2022 PA, and the performance of the modeling approaches depends on the availability of monitoring data which varies by location. Factors that likely contribute to poorer model performance often coincide with relatively low ambient PM
                        <E T="52">2.5</E>
                         concentrations, in areas where predicted exposures are at a greater distance to monitors, and under conditions where the reliability and availability of key datasets (
                        <E T="03">e.g.,</E>
                         air quality modeling) are limited. Thus, uncertainty in hybrid model predictions becomes an increasingly important consideration as lower predicted concentrations are considered.

                        Regardless of whether a study uses monitoring data or a hybrid modeling approach when estimating PM
                        <E T="52">2.5</E>
                         exposures, one key limitation that persists is associated with the interpretation of the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and how they compare to design values, the metric that describes the air quality status of a given area relative to the NAAQS.

                         As discussed above in section II.B.3.b, the overall mean PM
                        <E T="52">2.5</E>
                         concentrations reported by key epidemiologic studies reflect averaging of short- or long-term PM
                        <E T="52">2.5</E>
                         exposure estimates across location (

                         over several years). For monitor-based studies, the comparison is somewhat more straightforward than for studies that use hybrid modeling methods, as the monitors used to estimate exposure in the epidemiologic studies are generally the same monitors that are used to calculate design values for a given area. It is expected that areas meeting a PM
                        <E T="52">2.5</E>
                         standard with a particular level would be expected to have average PM

                        <PRTPAGE P="16249"/>
                        average concentration in an area can be smaller or larger than analyses presented above in section I.D.5.a, likely depending on factors such as the number of monitors, monitor siting characteristics, and the distribution of ambient PM
                        <E T="52">2.5</E>
                         concentrations. For studies that use hybrid modeling methods to estimate PM
                        <E T="52">2.5</E>
                         concentrations, the comparison between study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and design values is more complicated given the variability in the modeling methods, temporal scales (
                        <E T="03">i.e.,</E>
                         daily versus annual), and spatial scales (

                         nationwide versus urban) across studies. Analyses above in section I.D.5.b and detailed more in the 2022 PA (U.S. EPA, 2022b, section 2.3.3.2.4) present a comparison between two hybrid modeling surfaces, which explored the impact of these factors on the resulting mean PM
                        <E T="52">2.5</E>
                         concentrations and provided additional information about the relationship between mean concentrations from studies using hybrid modeling methods and design values. However, the results of those analyses only reflect two surfaces and two types of approaches, so uncertainty remains in understanding the relationship between estimated modeled PM
                        <E T="52">2.5</E>
                         concentrations and design values more broadly across hybrid modeling studies. Moreover, this analysis was completed using two hybrid modeling methods that estimate PM

                         concentrations in the U.S., thus an additional uncertainty includes understanding the relationship between modeled PM

                         and other pollutants (

                         ozone, nitrogen dioxide, and carbon monoxide) are correlated, it can be difficult to distinguish whether attenuation of effects in some studies results from copollutant confounding or collinearity with other pollutants in the ambient mixture (U.S. EPA, 2019a, section 1.5.1; U.S. EPA, 2022a, section 2.2.1). Studies evaluated in the 2019 ISA and ISA Supplement further examined the potential confounding effects of both gaseous and particulate copollutants on the relationship between long- and short-term PM
                        <E T="52">2.5</E>
                         exposure and health effects. As noted in the Appendix to the 2019 ISA (U.S. EPA, 2019a, Table A-1), copollutant models are not without their limitations, such as instances for which correlations are high between pollutants resulting in greater copollutant confounding bias in results. However, the studies continue to provide evidence indicating that associations with PM
                        <E T="52">2.5</E>
                         are relatively unchanged in copollutants models (U.S. EPA, 2019a, section 1.5.1; U.S. EPA, 2022a, section 2.2.1).
                    </P>
                    <P>
                        Another area of uncertainty is associated with other potential confounders, beyond copollutants. Some studies have expanded the examination of potential confounders to not only include copollutants, but also systematic evaluations of the potential impact of inadequate control from long-term temporal trends and weather (U.S. EPA, 2019a, section 11.1.5.1). Analyses examining these covariates further confirm that the relationship between PM
                        <E T="52">2.5</E>
                         exposure and mortality is unlikely to be biased by these factors. Other studies have explored the use of alternative methods for confounder control to more extensively account for confounders and are more robust to model misspecification that can further inform the causality determination for long-term and short-term PM
                        <E T="52">2.5</E>
                         and mortality and cardiovascular effects (U.S. EPA, 2019a, section 11.2.2.4; U.S. EPA, 2022a, sections 3.1.1.3, 3.1.2.3, 3.2.1.2, and 3.2.2.3). These studies indicate that bias from unmeasured confounders can occur in either direction, although controlling for these confounders did not result in the elimination of the association, but instead provided additional support for associations between long-term PM
                        <E T="52">2.5</E>
                         exposure and mortality when accounting for additional confounders (U.S. EPA, 2022a, section 3.2.2.2.6).

                    <P>
                        Another important limitation associated with the evidence is that, while epidemiologic studies indicate associations between PM
                        <E T="52">2.5</E>
                         and health effects, the currently available evidence does not identify particular PM
                        <E T="52">2.5</E>
                         concentrations that do not elicit health effects. Rather, health effects can occur over the entire distribution of ambient PM
                        <E T="52">2.5</E>
                         concentrations evaluated, and epidemiologic studies conducted to date do not identify a population-level threshold below which it can be concluded with confidence that PM

                        -related effects do not occur.

                        , with some recent studies providing evidence for either a sublinear, linear, or supralinear relationship at these lower concentrations (U.S. EPA, 2019a, section 11.2.4; U.S. EPA, 2022a, section 2.2.3.2).

                    <P>
                        There are also a number of uncertainties and limitations associated with the experimental evidence (
                        <E T="03">i.e.,</E>
                         controlled human exposure studies and animal toxicological studies). With respect to controlled human exposure studies, the PA recognizes that these studies include a small number of individuals compared to epidemiologic studies. Additionally, these studies tend to include generally healthy adult individuals, who are at a lower risk of experiencing health effects. These studies, therefore, often do not include populations that are at increased risk of PM
                        <E T="52">2.5</E>
                        -related health effects, including children, older adults, or individuals with pre-existing conditions. As such, these studies are somewhat limited in their ability to inform at what concentrations effects may be elicited in at-risk populations. With respect to animal toxicological studies, while these studies often examine more severe health outcomes and longer exposure durations and higher exposure concentrations than controlled human exposure studies, there is uncertainty in extrapolating the effects seen in animals, and the PM
                        <E T="52">2.5</E>

The evaluation and integration of the scientific evidence in the ISA focuses on evaluating the findings from the body of evidence across disciplines, including evaluating the strengths and weaknesses in the overall collection of studies across disciplines. Integrating evidence across disciplines can strengthen causal inference, such that a weak inference from one line of evidence can be addressed by other lines of evidence, and coherence of these lines of evidence can add support to a cause-effect interpretation of the association. Evaluation and integration of the evidence also includes consideration of uncertainties that are inherent in the scientific findings (U.S. EPA, 2015, pp. 13-15), some of which are described above.</P>

                        In addition to the overall risk assessment, the 2022 PA also includes an at-risk analysis and estimates exposures and health risks of specific populations identified as at-risk that would be allowed under the current and potential alternative standards to further inform the Administrator's conclusions regarding the adequacy of the public health protection provided by the current primary PM

                         concentrations are limited as they rely on model predictions, are based on emission changes scaled by fixed percentages, and use only two of the full set of possible emission scenarios and linear interpolation/extrapolation to adjust air quality that may not fully capture potential non-linearities associated with real-world changes in air quality. Additionally, the selection of case study areas is limited to urban areas predominantly located CA and in the Eastern U.S. that are controlled by the annual standard. While the risk assessment does not report quantitative uncertainty in the risk estimates as exposure concentrations are reduced, it does provide information on the distribution of concentrations associated with the risk estimates when evaluating progressively lower alternative annual standards. Based on these data, as lower alternative annual standards are evaluated, larger proportions of the distributions in risk occur at or below 10 μg/m
                        <SU>3</SU>
                         (at concentrations below or near most of the study-reported means from the key U.S. epidemiologic studies) and at or below 8 μg/m

                        Similarly, the at-risk analysis is also subject to many of these same uncertainties noted above. Additionally, the at-risk analysis included C-R functions from only one study (Di et al., 2017b), which reported associations between long-term PM
                        <E T="52">2.5</E>
                         exposures and mortality, stratified by race/ethnicity, in populations age 65 and older, as opposed to the multiple studies used in the overall risk assessment to convey risk estimate variability. These and other sources of uncertainty in the overall risk assessment and the at-risk analyses are characterized in more depth in the 2022 PA (U.S. EPA, 2022b, section 3.4.1.7, section 3.4.1.8, Appendix C, section C.3).

                        The approach to reviewing the primary standards is consistent with requirements of the provisions of the CAA related to the review of the NAAQS and with how the EPA and the courts have historically interpreted the CAA. As discussed in section I.A above, these provisions require the Administrator to establish primary standards that, in the Administrator's judgment, are requisite (
                        <E T="03">i.e.,</E>
                         neither more nor less stringent than necessary) to protect public health with an adequate margin of safety. Consistent with the Agency's approach across all NAAQS reviews, the EPA's approach to informing these judgments is based on a recognition that the available health effects evidence generally reflects a continuum that includes ambient air exposures for which scientists generally agree that health effects are likely to occur through lower levels at which the likelihood and magnitude of response become increasingly uncertain. The CAA does not require the Administrator to establish a primary standard at a zero-risk level or at background concentration levels, but rather at a level that reduces risk sufficiently so as to protect public health, including the health of sensitive groups, with an adequate margin of safety.

                        As part of its review of the 2019 draft PA, the CASAC provided advice on the adequacy of the public health protection afforded by the current primary PM
                        <E T="52">2.5</E>
                         standards. Its advice is documented in

                        a letter sent to the EPA Administrator (Cox, 2019b). In this letter, the committee recommended retaining the current 24-hour PM
                        <E T="52">2.5</E>
                         standard but did not reach consensus on whether the scientific and technical information support retaining or revising the current annual standard. In particular, though the CASAC agreed that there is a long-standing body of health evidence supporting relationships between PM
                        <E T="52">2.5</E>
                         exposures and various health outcomes, including mortality and serious morbidity effects, individual CASAC members “differ[ed] in their assessments of the causal and policy significance of these associations” (Cox, 2019b, p. 8 of consensus responses). Drawing from this evidence, “some CASAC members” expressed support for retaining the current annual standard while “other members” expressed support for revising that standard in order to increase public health protection (Cox, 2019b, p.1 of letter). These views are summarized below.
                    </P>
                    <P>
                        The CASAC members who supported retaining the current annual standard expressed the view that substantial uncertainty remains in the evidence for associations between PM
                        <E T="52">2.5</E>
                         exposures and mortality or serious morbidity effects. These committee members asserted that “such associations can reasonably be explained in light of uncontrolled confounding and other potential sources of error and bias” (Cox, 2019b, p. 8 of consensus responses). They noted that associations do not necessarily reflect causal effects, and they contended that recent epidemiologic studies assessed in the 2019 ISA that report positive associations at lower estimated exposure concentrations mainly confirm what was anticipated or already assumed in setting the 2012 NAAQS. In particular, they concluded that such studies have some of the same limitations as prior studies and do not provide new information calling into question the existing standard. They further asserted that “accountability studies provide potentially crucial information about whether and how much decreasing PM
                        <E T="52">2.5</E>
                         causes decreases in future health effects” (Cox, 2019b, p. 10 of consensus responses), and they cited recent reviews (
                        <E T="03">i.e.,</E>
                         Henneman et al., 2017; Burns et al., 2019) to support their position that in such studies, “reductions of PM
                        <E T="52">2.5</E>
                         concentrations have not clearly reduced mortality risks” (Cox, 2019b, p. 8 of consensus responses). Thus, the committee members who supported retaining the current annual standard advise that, “while the data on associations should certainly be carefully considered, this data should not be interpreted more strongly than warranted based on its methodological limitations” (Cox, 2019b, p. 8 of consensus responses).
                    </P>
                    <P>These members of the CASAC further concluded that the quantitative risk assessment included in the 2019 draft PA does not provide a valid basis for revising the current standards. This conclusion was based on concerns that (1) “the risk assessment treats regression coefficients as causal coefficients with no justification or validation provided for this decision;” (2) the estimated regression concentration-response functions “have not been adequately adjusted to correct for confounding, errors in exposure estimates and other covariates, model uncertainty, and heterogeneity in individual biological (causal) [concentration-response] functions;” (3) the estimated concentration-response functions “do not contain quantitative uncertainty bands that reflect model uncertainty or effects of exposure and covariate estimation errors;” and (4) “no regression diagnostics are provided justifying the use of proportional hazards . . . and other modeling assumptions” (Cox, 2019b, p. 9 of consensus responses). These committee members also contended that details regarding the derivation of concentration-response functions, including specification of the beta values and functional forms, were not well-documented, hampering the ability of readers to evaluate these design details. Thus, these members “think that the risk characterization does not provide useful information about whether the current standard is protective” (Cox, 2019b, p. 11 of consensus responses).</P>

                        Drawing from their evaluation of the evidence and the risk assessment in the 2019 draft PA, these committee members concluded that “the Draft PM PA does not establish that new scientific evidence and data reasonably call into question the public health protection afforded by the . . . 2012 PM
                        <E T="52">2.5</E>

                    <P>
                        In contrast, “[o]ther members of CASAC conclude[d] that the weight of the evidence, particularly reflecting recent epidemiology studies showing positive associations between PM
                        <E T="52">2.5</E>
                         and health effects at estimated annual average PM

                         [standard] to protect public health with an adequate margin of safety” (Cox, 2019b, p.1 of letter). The committee members who supported this conclusion noted that the body of health evidence for PM
                        <E T="52">2.5</E>
                         not only includes the repeated demonstration of associations in epidemiologic studies, but also includes support for biological plausibility established by controlled human exposure and animal toxicology studies. They pointed to recent studies demonstrating that the associations between PM
                        <E T="52">2.5</E>
                         and health effects occur in a diversity of locations, in different time periods, with different populations, and using different exposure estimation and statistical methods. They concluded that “the entire body of evidence for PM health effects justifies the causality determinations made in the Draft PM ISA” (Cox, 2019b, p. 8 of consensus responses).

                    <P>
                        The members of the CASAC who supported revising the current annual standard particularly emphasized recent findings of associations with PM

                        <SU>3</SU>
                         are excluded from analyses. They found it “highly unlikely” that the extensive body of evidence indicating positive associations at low estimated exposures could be fully explained by confounding or by other non-causal explanations (Cox, 2019b, p. 8 of consensus responses). They additionally concluded that “the risk characterization does provide a useful attempt to understand the potential impacts of alternate standards on public health risks” (Cox, 2019b, p. 11 of consensus responses). These CASAC members concluded that the available evidence reasonably calls into question the protection provided by the current primary PM
                        <E T="52">2.5</E>
                         standards and supports revising the annual standard to increase that protection (Cox, 2019b).

                        As a part of this reconsideration, the CASAC reviewed the 2021 draft PA (developed to support the reconsideration as described in section I.C.5 above). As a part of their review of the 2021 draft PA, the CASAC provided advice on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards. The range of views summarized here generally reflects differing judgments as to the relative weight to place on various types of evidence, the risk-based information, and the associated uncertainties, as well as differing judgments about the importance of various PM

                        In its comments on the 2021 draft PA, the CASAC stated that: “[o]verall the CASAC finds the Draft PA to be well-

                        written and appropriate for helping to `bridge the gap' between the agency's scientific assessments and quantitative technical analyses, and the judgments required of the Administrator in determining whether it is appropriate to retain or revise the National Ambient Air Quality Standards (NAAQS)” (Sheppard, 2022a, p. 1 of consensus letter). The CASAC also stated that the “[d]raft PA adequately captures and appropriately characterizes the key aspects of the evidence assessed and integrated in the 2019 ISA and Draft ISA Supplement of PM

                        <E T="52">2.5</E>

                         standard, “all CASAC members agree that the current level of the annual standard is not sufficiently protective of public health and should be lowered” (Sheppard, 2022a, p. 2 of consensus letter). Additionally, “the CASAC reached consensus that the indicator, form, and averaging time should be retained, without revision” (Sheppard, 2022a, p. 2 of consensus letter). With regard to the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard, the CASAC had differing recommendations for the appropriate range for an alternative level. The majority of the CASAC “judge[d] that an annual average in the range of 8-10 μg/m
                        <SU>3</SU>
                        ” was most appropriate, while the minority of the CASAC members stated that “the range of the alternative standard of 10-11 μg/m
                        <SU>3</SU>
                         is more appropriate” (Sheppard, 2022a, p. 16 of consensus responses). The CASAC did highlight, however, that “the alternative standard level of 10 μg/m
                        <SU>3</SU>
                         is within the range of acceptable alternative standards recommended by all CASAC members, and that an annual standard below 12 μg/m
                        <SU>3</SU>
                         is supported by a larger and coherent body of evidence” (Sheppard, 2022a, p. 16 of consensus responses).

In particular, these members cited recent U.S.- and Canadian-based epidemiologic studies that show positive associations between PM
                        <E T="52">2.5</E>
                         exposure and mortality with study-reported mean concentrations below 10 μg/m
                        <SU>3</SU>
                        . Further, these members also noted that the lower portions of the air quality distribution (
                        <E T="03">i.e.,</E>
                         concentrations below the mean) provide additional information to support associations between health effects and PM

                         concentrations lower than the reported long-term mean concentration. In addition, the CASAC members recognized that the available evidence has not identified a threshold concentration, below which an association no longer remains, pointing to the conclusion in the draft ISA Supplement that the “evidence remains clear and consistent in supporting a no-threshold relationship, and in supporting a linear relationship for PM
                        <E T="52">2.5</E>

                         air quality distributions with overall mean concentrations below 9.6 μg/m

                         (Sheppard, 2022a, p. 17 of consensus responses). In so doing, the minority of the CASAC specifically noted the variability in the relationship between study-reported means and area annual design values based on the methods utilized in the studies, noting that design values are generally higher than area average exposure levels. Further, the minority of the CASAC stated that “uncertainties related to copollutants and confounders make it difficult to justify a recommendation below 10-11 μg/m
                        <SU>3</SU>
                        ” (Sheppard, 2022a, p. 17 of consensus responses). Finally, the minority of the CASAC placed less weight on the risk assessment results, noting large uncertainties, including the approaches used for adjusting air quality to simulate just meeting the current and alternative standards.

                         standard, in their review of the 2021 draft PA, the CASAC did not reach consensus regarding the adequacy of the public health protection provided by the current standard. As described further below, the majority of the CASAC members concluded “that the available evidence calls into question the adequacy of the current 24-hour standard” (Sheppard, 2022a, p. 3 of consensus letter), while the minority of the CASAC members agreed with “the EPA's preliminary conclusion [in the draft PA] to retain the current 24-hour PM
                        <E T="52">2.5</E>
                         standard without revision” (Sheppard, 2022a, p. 4 of consensus letter). The CASAC recommended that in future reviews, the EPA should also consider alternative forms for the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. Specifically, the CASAC “suggests considering a rolling 24-hour average and examining alternatives to the 98th percentile of the 3-year average,” pointing to concerns that computing 24-hour average PM
                        <E T="52">2.5</E>
                         concentrations using the current midnight-to-midnight timeframe could potentially underestimate the effects of high 24-hour exposures, especially in areas with wood-burning stoves and wintertime stagnation (Sheppard, 2022a, p. 18 of consensus responses).

                    <P>
                        As noted above, the majority of the CASAC favored revising the level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, suggesting that a range of 25-30 μg/m
                        <SU>3</SU>
                         would be adequately protective. In so doing, the majority of the CASAC placed weight on the available epidemiologic evidence, including epidemiologic studies that restricted analyses to 24-hour PM
                        <E T="52">2.5</E>
                         concentrations below 25 μg/m
                        <SU>3</SU>
                        . These members also placed weight on results of controlled human exposure studies with exposures close to the current standard, which they note provide support for the epidemiologic evidence to lower the standard. These members noted the limitations in using controlled human exposure studies alone in considering the adequacy of the 24-hour standard, recognizing that controlled human exposure studies preferentially recruit less susceptible individuals and have a typical exposure duration shorter than 24 hours. These members also placed “greater weight on the scientific evidence than on the values estimated by the risk assessment,” citing their concerns that the risk assessment “may not adequately capture areas with wintertime stagnation and residential wood-burning where the annual standard is less likely to be protective” (Sheppard, 2022a, p. 17 of consensus responses). Furthermore, these CASAC members “also are less confident that the annual standard could adequately protect against health effects of short-term exposures” (Sheppard, 2022a

                        The minority of the CASAC agreed with the EPA's preliminary conclusion in the 2021 draft PA to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, the minority of the CASAC placed greater weight on the risk assessment, noting that the risk 
                        <PRTPAGE P="16254"/>
                        assessment accounts for both the level and the form of the current standard and the manner by which attainment with the standard is determined. Further, the minority of the CASAC stated that the “risk assessment indicates that the annual standard is the controlling standard across most of the urban study areas evaluated and revising the level of the 24-hour standard is estimated to have minimal impact on the PM
                        <E T="52">2.5</E>
                        -associated risks” and therefore, “the annual standard can be used to limit both long- and short-term PM
                        <E T="52">2.5</E>
                         concentrations” (Sheppard, 2022a, p. 18 of consensus responses). Further, the minority of the CASAC placed more weight on the controlled human exposure studies, which show “effects at PM
                        <E T="52">2.5</E>
                         concentrations well above those typically measured in areas meeting the current standards” and which suggest that “the current standards are providing adequate protection against these exposures” (Sheppard, 2022a, p. 18 of consensus responses).

                        While the CASAC members expressed differing opinions on the appropriate revisions to the current standards, they did “find that both primary standards, 24-hour and annual, are critical to protect public health given the evidence on detrimental health outcomes at both short-term and long-term exposures including peak events” (Sheppard, 2022a, p. 13 of consensus responses). The comments from the CASAC also took note of uncertainties that remain in this reconsideration of the primary PM
                        <E T="52">2.5</E>
                         standards and they identified a number of additional areas for future research and data gathering and dissemination that would inform future reviews of the primary PM

                         standard from its current level of 12.0 µg/m

                         to within the range of 9.0 to 10.0 µg/m

                         standard (88 FR 5558, January 27, 2023), the Administrator carefully considered the assessment of the current evidence and conclusions reached in the 2019 ISA and ISA Supplement; the currently available exposure and risk information, including associated limitations and uncertainties, described in detail in the 2022 PA; the considerations and staff conclusions and associated rationales presented in the 2022 PA; the advice and recommendations from the CASAC; and public comments that had been offered up to that point (88 FR 5558, January 27, 2023).

                        In reaching his proposed conclusions on whether the currently available scientific evidence and quantitative risk-based information support or call into question the adequacy of the public health protection afforded by the current primary PM
                        <E T="52">2.5</E>
                         standards, and as is the case with NAAQS reviews in general, the extent to which the current primary PM

                         standards are judged to be adequate will depend on a variety of factors, including science policy and public health policy judgments to be made by the Administrator on the strength and uncertainties of the scientific evidence. The factors relevant to judging the adequacy of the standards also include the interpretation of, and decisions as to the weight to place on, different aspects of the results of the risk assessment for the study areas included and the associated uncertainties. Thus, in reaching proposed conclusions of the current standards, the Administrator recognized that such a determination depends in part on judgments regarding aspects of the evidence and risk estimates, and judgments about the degree of protection that is requisite to protect public health with an adequate margin of safety.

                    <P>
                        The Administrator's full rationale for his proposed conclusions is presented in section II.D.3 of proposal (88 FR 5658, January 27, 2023), but is also briefly summarized here. In reaching the proposed decision to revise the annual standard level to 9-10 µg/m
                        <SU>3</SU>
                        , the Administrator placed weight on the full body of scientific information. He noted that the 2019 ISA finds that exposure to PM
                        <E T="52">2.5</E>
                         causes mortality and cardiovascular effects and is likely to cause respiratory effects, cancer, and nervous system effects as detailed further in section II.B.1 of the proposal. As detailed further in section II.B.4 of the proposal, he additionally noted that the 2019 ISA identifies at-risk populations at greater risk of health effects from exposure to PM
                        <E T="52">2.5</E>
                        , including children, older adults, people with pre-existing respiratory or cardiovascular disease, minority populations, and low socioeconomic status (SES) populations.
                    </P>
                    <P>
                        The Administrator also recognized that epidemiologic studies provide the strongest scientific evidence when evaluating the adequacy of the level of the annual standard. He noted that there is no specific point in the air quality distribution of any epidemiologic study that represents a `bright line' at and above which effects have been observed and below which effects have not been observed. In his proposed decision, he noted previous decision-making frameworks, which placed weight on values at or near the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, which is where the most confidence in the reported association of the epidemiologic study exists. He further noted that there are a number of epidemiologic studies available in this reconsideration that use new PM
                        <E T="52">2.5</E>
                         exposure estimation techniques (
                        <E T="03">e.g.,</E>
                         hybrid modeling) that were not used in epidemiologic studies that were available in previous reviews. These recent epidemiologic studies that use new exposure estimation techniques report long-term mean PM
                        <E T="52">2.5</E>
                         concentrations that are well below corresponding design values, which is an important consideration in reaching decisions on the level of the annual PM
                        <E T="52">2.5</E>
                         standard.

                    <P>
                        In reaching his proposed decision, the Administrator noted that a level of 9-10 µg/m
                        <SU>3</SU>
                         would near or below the reported 25th percentiles in key U.S. based epidemiologic studies, while also recognizing that he has less confidence in the magnitude and significance of the association at even lower percentiles (
                        <E T="03">e.g.,</E>
                         10th percentile), where even fewer health events are observed. The Administrator also noted that a proposed level of 9-10 µg/m
                        <SU>3</SU>
                         would be near the mean PM
                        <E T="52">2.5</E>
                         reported in Canadian based studies, though he also recognized that there are a number of factors associated with the studies in Canada (
                        <E T="03">e.g.,</E>
                         exposure environments) that make it more difficult to compare mean concnetrations from Canadian studies to design values, which determine compliance with the standard in the U.S.
                    </P>
                    <P>
                        The Administrator took note of additional pieces of scientific evidence, which were not available in previous reviews, including restricted analyses, which support that the association seen in epidemiologic studies does not just occur from the peaks of the exposure distribution. Additionally, he notes that a level of 9-10 µg/m
                        <SU>3</SU>
                         would be below the starting concentration in newly available accountability studies, though he did note that it is more difficult to interpret these studies in the context of selecting the level of the annual PM
                        <E T="52">2.5</E>
                         standard.

                    <P>
                        Further, the Administrator took into consideration the advice of the CASAC, noting that all members included 10 µg/m
                        <SU>3</SU>
                         in their recommended range, and that the proposed range of 9-10 µg/m
                        <SU>3</SU>
                         for the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard was within the range recommended by the majority of the CASAC.

                    <P>
                        In reaching the proposed conclusion of a range between 9-10 µg/m
                        <SU>3</SU>
                        , the Administrator noted that a level as high 
                        <PRTPAGE P="16255"/>
                        as 11 µg/m
                        <SU>3</SU>
                         might not provide an adequate margin of safety, given that 11 µg/m
                        <SU>3</SU>
                         was well above many of the epidemiologic study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations. Additionally, the Administrator noted the uncertainties associated with the scientific and quantitative information supporting a level as low as 8 µg/m
                        <SU>3</SU>
                        , which call into question the potential public health improvements of a standard below 9 µg/m
                        <SU>3</SU>
                        . The Administrator specifically noted the lack of key U.S. studies with mean concentrations below 9.3 µg/m
                        <SU>3</SU>
                         and he further noted that the risk assessment suggests that the risk remaining under a standard of 8 µg/m
                        <SU>3</SU>
                         would occur at very low concentrations (
                        <E T="03">e.g.,</E>
                         mainly 7 µg/m

                        As such, the Administrator's proposed decision noted that the current PM

                         annual standard did not adequately provide requisite protection against exposures to PM
                        <E T="52">2.5</E>
                         and that a proposed range of 9-10 µg/m
                        <SU>3</SU>
                         would provide an adequate margin of safety.

                    <P>
                        In his proposed decision to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard with a level of 35 µg/m
                        <SU>3</SU>
                        , the Administrator first considered the scientific information related to short-term exposures to PM
                        <E T="52">2.5</E>
                         and health effects. He noted that the controlled human exposure studies are the strongest line of evidence for informing his conclusions regarding the adequacy of the current 24-hour standard. In so doing, the Administrator recognized that controlled human exposure studies are conducted with healthy adult volunteers and that these studies do not include individuals who may be at increased risk of PM
                        <E T="52">2.5</E>
                        -related health effects (
                        <E T="03">i.e.,</E>
                         children, older adults, people with pre-existing diseases). He also noted that the effects observed in the controlled human exposure studies (
                        <E T="03">e.g.,</E>
                         changes in vascular function) are not effects that are judged to be clearly adverse. He recognized the most consistent evidence of effects in these studies occurs at higher concentrations (
                        <E T="03">e.g.,</E>
                         &gt;120 µg/m
                        <SU>3</SU>
                        ) following 1-5 hour exposures, and that one study observed effects at concentrations as low as 38 µg/m
                        <SU>3</SU>
                         following 4-hour exposures. However, the Administrator reiterated that these studies do not tell us at exactly what concentrations an adverse effect might occur, especially for at-risk populations. As noted above in section II.A.2.c, controlled human exposure studies tend to include generally healthy adult individuals who are at a lower risk of experiencing health effects, and often do not include at-risk populations (
                        <E T="03">e.g.,</E>
                         children, older adults, or individuals with pre-existing conditions). As such, the Administrator recognized that these studies are somewhat limited in their ability to inform at what concentrations effects may be elicited in in at-risk populations. The Administrator also considered air quality analyses in the 2022 PA that demonstrate that there will be very few, if any, days with PM
                        <E T="52">2.5</E>
                         concentrations at levels evaluated in controlled human exposure studies that are associated with effects in areas that meet the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard.
                    </P>
                    <P>
                        The Administrator also noted that as, in previous PM NAAQS reviews, the protection provided by the suite of standards (
                        <E T="03">e.g.,</E>
                         annual and 24-hour standards) is evaluated together. He noted that the annual standard is the controlling standard in most areas of the country. He also considered air quality analyses in the 2022 PA that suggest that revision of the annual standard to a level between 9-10 µg/m
                        <SU>3</SU>
                         would also control 24-hour PM
                        <E T="52">2.5</E>
                         concentrations in most areas to, or below, 30 µg/m
                        <SU>3</SU>
                        . Finally, the Administrator noted the agreement with the advice from the minority of CASAC and additionally noted the limited rationale and evidence provided by the majority CASAC's recommendation to support revision of the 24-hour standard. As such, the Administrator proposed to retain the current 24-hour standard with its level of 35 µg/m
                        <SU>3</SU>
                        .

                    <P>
                        Additionally, the Administrator proposed to conclude that it is appropriate to retain all other elements (

                        <E T="52">2.5</E>
                         standard, a number of commenters, primarily those from industry and industry groups, non-governmental organizations, and some State and local governments, disagree with the EPA's proposed decision to revise the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. These commenters generally expressed the view that the current standards provide the requisite degree of public health protection and should be retained, consistent with the 2020 final decision. In supporting their view, these commenters assert that the scientific evidence available in this reconsideration is essentially unchanged since the 2020 final decision and that the additional scientific evidence and quantitative risk information available for the reconsideration does not support strengthening the primary annual PM
                        <E T="52">2.5</E>
                         standard. These commenters also assert that uncertainties associated with the available scientific evidence have not changed since the 2020 final decision, and they note that these uncertainties were essential factors in the then-Administrator's decision to retain the primary annual PM
                        <E T="52">2.5</E>
                         standard. These commenters argue that, while the current Administrator acknowledges these uncertainties, he does not place enough weight on them in reaching his conclusions regarding the current standard. The commenters specifically highlight uncertainties related to exposure misclassification, confounding, and other sources of potential bias, which they claim supports retaining the current level of the annual standard. These commenters also note that these uncertainties were emphasized by the minority of the CASAC in their review of the 2021 draft PA, and the commenters further suggest that the lack of consensus from the CASAC on the appropriate level for the primary annual PM

                        In contrast, other commenters, primarily from public health and environmental organizations, some State and local elected representatives, and some State and local government agencies agree with the EPA's proposed decision that the primary annual PM

                         standard is not adequate. These commenters support revising the level of the primary annual PM

In particular, these commenters agree with the EPA's conclusions about the strength of the scientific evidence, including uncertainties, and they emphasize that the CASAC reached consensus in their review of the 2021 draft PA that the current primary annual PM

                         standard is not adequate. Some of these commenters also note that a revised primary annual PM
                        <E T="52">2.5</E>
                         standard would result in significant public health benefits by reducing morbidity and mortality associated with PM

                        The EPA agrees with commenters that the primary annual PM

                         exposures. As noted above, epidemiologic studies demonstrate generally positive and often statistically significant associations between PM

                         exposures and health effects. Such studies report associations between estimated PM

                         exposures and non-accidental, cardiovascular, or respiratory mortality; cardiovascular or respiratory hospitalizations or emergency room visits; and other mortality/morbidity outcomes (

                         exposures could lead to the serious effects reported in many population-level epidemiologic studies, including support for pathways that could lead to cardiovascular, respiratory, nervous system, and cancer-related effects. Moreover, these recent epidemiologic studies strengthen support for health effect associations at PM

                        Additionally, as discussed in more detail in section I.C.5.b above, the ISA Supplement focused on studies that were most likely to inform decisions on the appropriate standard, but not to reassess areas that, based on the assessment of available science published since the cutoff date of the 2019 ISA and through 2021, were judged unlikely to have new information that would be useful for the Administrator's decision making. The ISA Supplement included U.S. and Canadian epidemiologic studies for health effect categories where the 2019 ISA concluded a causal relationship (

                         exposure and cardiovascular effects and mortality. Additionally, studies that employ alternative methods for confounder control, as described in II.A.2.a above and in Table 3-11 and of the 2022 PA (U.S. EPA, 2022b), use a variety of statistical methods to control for confounding bias. These studies consistently report positive associations, which further supports the broader body of epidemiologic evidence for both cardiovascular effects and mortality.

                        Thus, in considering the available scientific evidence to inform conclusions on the adequacy of the primary PM
                        <E T="52">2.5</E>
                         standards, the Administrator recognizes that the 2019 ISA and the ISA Supplement together provides a strong scientific foundation for concluding that the current primary PM
                        <E T="52">2.5</E>
                         standards are not adequate.

                         standard could allow a substantial number of deaths in the U.S. Although the Administrator recognizes that while the risk estimates can help to place the evidence for specific health effects into a broader public health context, they should be considered along with the inherent uncertainties and limitations of such analyses when informing judgments about the potential for additional public health protection associated with PM
                        <E T="52">2.5</E>
                         exposures and related health effects. The Administrator takes into consideration these uncertainties, which are described in more detail in section II.A.3.b above, but notes that the general magnitude of risk estimates supports the potential for significant public health impacts, particularly for lower alternative annual standard levels.
                    </P>
                    <P>In the CASAC's review of the 2019 draft PA, the CASAC did not reach consensus on whether the current annual standard is adequate, with the majority of the CASAC recommending that the annual standard be retained and the minority of the CASAC recommending that the standard be revised.

                    <P>
                        The EPA disagrees with the commenters who state that the available scientific and quantitative information available in this reconsideration does not provide support for the current Administrator to reach a different decision than the then-Administrator reached in the 2020 final action. The EPA agrees with these commenters that there are uncertainties associated with the currently available scientific evidence. The EPA has considered these uncertainties extensively both in reaching conclusions in the 2022 PA (U.S. EPA, 2022b, sections 3.4.3, 3.6.1, and 4.6.3) and in the proposal (88 FR 5604, 5609, January 27, 2023), and the EPA addresses more detailed public comments about these uncertainties, including those related to copollutant confounding, unmeasured confounding, and temporal and spatiotemporal confounding, in the Response to Comments document. However, we disagree with the commenters that the evidence does not provide support for the Administrator's conclusion that the current primary annual PM
                        <E T="52">2.5</E>
                         standard is not adequate to protect public health with an adequate margin of safety, and should be revised. As described above, epidemiologic studies in the 2019 ISA and the ISA Supplement support and extend the evidence evaluated in the 2009 ISA, through studies conducted in diverse populations and geographic locations, using various statistical models and approaches to control for potential confounders, and using a variety of exposure assessment methodologies. Therefore, the consistent, positive associations reported across studies (U.S. EPA, 2019a, Figures 11-1 and 11-18; U.S. EPA, 2022a) are unlikely to be to be the result of unmeasured confounding and other biases are unlikely to account for the consistent positive associations observed across epidemiologic studies.

                    <P>
                        Additionally, this reconsideration includes epidemiologic studies that were not before the then-Administrator for consideration in reaching his final decisions at the time of the 2020 decision and that specifically evaluate 
                        <PRTPAGE P="16257"/>
                        confounding using alternative methods for confounder control). These recent epidemiologic studies provide support for the current Administrator's conclusion that the suite of primary PM
                        <E T="52">2.5</E>
                         standards are not adequate. While confounding was an uncertainty noted by the then-Administrator in the 2020 decision, he recognized “that methodological study designs to address confounding, such as causal inference methods, are an emerging field of study” (85 FR 82710, December 18, 2020). The ISA Supplement considered studies that employed statistical approaches that attempt to more extensively account for confounders and are more robust to model misspecification (
                        <E T="03">i.e.,</E>
                         used alternative methods for confounder control),
                        <SU>92</SU>
                        <FTREF/>
                         given that such studies were highlighted by the CASAC in their review of the 2019 draft PA and identified in public comments on the 2020 proposal. Since the literature cutoff date for the 2019 ISA, multiple studies that employ alternative methods for confounder control have become available for consideration in the ISA Supplement and, subsequently, in this reconsideration. For example, one study before the Administrator in this reconsideration that was not available in the 2019 ISA is Schwartz et al. (2021), which used a causal modeling approach focused on exposure changes and controls for measured confounders by design in order to evaluate the association between long-term PM
                        <E T="52">2.5</E>
                         exposure and mortality in the Medicare population. The study authors found significant associations of PM
                        <E T="52">2.5</E>
                         with increased mortality rates using a causal modeling approach robust to omitted confounding. The results of this study and other studies in the ISA Supplement that employ alternative methods to control for confounders lend support to the robustness of positive associations between PM
                        <E T="52">2.5</E>
                         exposure and multiple morbidity and mortality endpoints exhibited across epidemiologic studies, and also indicate that unmeasured confounding and other biases are unlikely to account for the consistent positive associations observed across epidemiologic studies (U.S. EPA, 2022b, sections 3.1.1.3, 3.1.2.3, 3.2.1.3, and 3.2.2.3).

                             As noted in the ISA Supplement: “In the peer-reviewed literature, these epidemiologic studies are often referred to as causal inference studies or studies that used causal modeling methods. For the purposes of this Supplement, this terminology is not used to prevent confusion with the main scientific conclusions (

                             the causality determinations) presented within an ISA. In addition, as is consistent with the weight-of-evidence framework used within ISAs and discussed in the Preamble to the Integrated Science Assessments, an individual study on its own cannot inform causality, but instead represents a piece of the overall body of evidence” (U.S. EPA, 2022a, p. 1-3).

                        Further, the EPA disagrees with the commenters who argue that the Administrator did not appropriately consider the strengths and limitations of the health evidence in reaching his decision to revise the current primary annual PM

                         standard in this reconsideration. In reaching his proposed decision, the Administrator considered the entire body of evidence and how to appropriately weigh the uncertainties associated with the health evidence (88 FR 5617, January 27, 2023). Such an approach is consistent with setting standards that are neither more nor less stringent than necessary, recognizing that “Congress provided that the Administrator is to use his judgment in setting air quality standards precisely to permit him to act in the face of uncertainty,” the Administrator must set standards on “the frontiers of scientific and medical knowledge” and “Congress directed the Administrator to err on the side of caution in making the necessary decisions

                        Additionally, the EPA disagrees with the commenters that contend that there is no basis in this reconsideration for deviating from the previous Administrator's decision in 2020. It is well-established that in CAA section 109 Congress specifically left the determination of the requisite NAAQS to the judgment of the Administrator and, moreover, that “decisions about the appropriate NAAQS level must `necessarily . . . rest largely on policy judgments.' ”

                        In this reconsideration, both the existing corpus of scientific knowledge as well as the Administrator's policy judgments about how to interpret and weigh that evidence to protect public health with an adequate margin of safety have changed. The expansion of the air quality criteria to encompass additional studies, information and analyses in the ISA Supplement and 2022 PA, as well as the additional consideration of the scientific record by the CASAC and the public provided the Administrator with significant additional information on which to base his decision.

                         In addition, in this reconsideration, the Administrator is reaching different judgments about how to weigh the epidemiologic evidence, including the uncertainties in the scientific evidence, and how to ensure an adequate margin of safety to protect against uncertain harms, compared to the approach in the 2020 final decision. For example, as discussed in greater detail above in section II.A.1 and in the 2020 notice of final rulemaking (85 FR 82717, December 18, 2020), in considering the epidemiologic evidence as part of his decision to retain the current primary annual PM

                         standard in the 2020 decision, the then-Administrator placed weight on the mean of the study-reported means (or medians) (
                        <E T="03">i.e.,</E>
                         13.5 µg/m

                        <SU>3</SU>
                        . By contrast, in this reconsideration, the current Administrator has taken an approach more similar to how the EPA has considered study-reported mean PM

                        As such and further detailed in section II.B.4 below, in considering the adequacy of the current primary PM standards in this reconsideration, the Administrator has carefully considered the: (1) Policy-relevant evidence and conclusions contained in the 2019 ISA and 2022 ISA Supplement; (2) the quantitative information presented and 
                        <PRTPAGE P="16258"/>
                        assessed in the 2022 PA; (3) the evaluation of this evidence, the quantitative information, and the rationale and conclusions presented in the 2022 PA; (4) the advice and recommendations from the CASAC; and (5) public comments. The Administrator concludes that the current suite of primary PM
                        <E T="52">2.5</E>
                         standards are not adequate to protect public health with an adequate margin of safety.

                    <P>
                        The four basic elements of the NAAQS (indicator, averaging time, form, and level) are considered collectively in evaluating the health protection afforded by a standard. The EPA received relatively few comments on the averaging time and form for the primary PM
                        <E T="52">2.5</E>
                         standards, but those who did provide comments on these elements were primarily from public health and environmental organizations, State and local elected representatives, and State and local government agencies. Some commenters assert that the current 24-hour averaging time for the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard does not adequately protect against short-term peaks. These commenters further state that the 24-hour averaging time protects against chronic exposures but does not adequately protect against serious acute risks from certain sources such as prescribed burning. Also, a few commenters explicitly recommend that a subdaily averaging time would be more appropriate, although none of the commenters recommended a specific averaging time for consideration. Additionally, some commenters cite to the CASAC's advice in their review of the 2021 draft PA that future reviews of the PM NAAQS should include evaluation of alternative forms and averaging times of the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard.

                    <P>
                        The EPA disagrees with commenters that the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, with its 24-hour averaging time, does not adequately protect against short-term peaks and disagrees that that there is sufficient information to conclude that a subdaily averaging time would be more appropriate than a 24-hour averaging time. The EPA has reviewed the currently available scientific evidence and finds that it does not indicate that alternative averaging times would be more appropriate for the primary PM
                        <E T="52">2.5</E>
                         standards. Accordingly, the EPA concludes that it is appropriate to retain both the annual and 24-hour averaging times for standards meant to protect against long- and short-term PM

                        As noted in the proposal, the 2019 ISA and ISA Supplement found that the scientific evidence continues to provide strong support for health effect associations with both long-term (
                        <E T="03">e.g.,</E>
                         annual or multi-year) and short-term (
                        <E T="03">e.g.,</E>
                         mostly 24-hour) exposures to PM
                        <E T="52">2.5</E>
                        . Epidemiologic studies continue to provide strong support for health effects associated with short-term PM
                        <E T="52">2.5</E>
                         exposures based on 24-hour PM
                        <E T="52">2.5</E>
                         averaging periods, and we note that subdaily effect estimates are less consistent and, in some cases, smaller in magnitude (88 FR 5618, January 27, 2023). Controlled human exposure and panel-based studies of subdaily exposures typically examine subclinical effects rather than the more serious population-level effects that have been reported to be associated with 24-hour exposures (
                        <E T="03">e.g.,</E>
                         mortality, hospitalizations). Collectively, the 2019 ISA concludes that epidemiologic studies do not indicate that subdaily averaging periods are more closely associated with health effects than the 24-hour average exposure metric (U.S. EPA, 2019a, section 1.5.2.1). Additionally, the EPA notes that while recent controlled human exposure studies provide consistent evidence for cardiovascular effects following PM
                        <E T="52">2.5</E>
                         exposures for less than 24 hours (
                        <E T="03">i.e.,</E>
                         &lt;30 minutes to 5 hours), exposure concentrations in these studies are well-above the ambient concentrations typically measured in locations meeting the current standards (U.S. EPA, 2022a, section 3.3.3.1). Therefore, this information does not indicate that a revision to the averaging time is needed to provide additional protection against subdaily PM
                        <E T="52">2.5</E>
                         exposures, beyond that provided by the current primary standards. This conclusion is also supported by the advice given to EPA by the CASAC in their review of the 2021 draft PA, which reached consensus that averaging times for the standards should be retained, without revision (Sheppard, 2022a, p. 2 of consensus letter).

                         For all of these reasons, the Administrator concludes that the currently available evidence does not support considering alternatives to the annual and 24-hour averaging times for standards meant to protect against long- and short-term PM
                        <E T="52">2.5</E>

                             standard but did recommend that the standard be retained because the available evidence does not call into question its adequacy (Cox, 2019b, p. 3 of consensus letter).

                        Multiple commenters, primarily from public health and environmental organizations, recommend revising the form of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard to a 99th percentile to provide increased public health protection against peak PM
                        <E T="52">2.5</E>
                         exposures, particularly for at-risk populations. These commenters express concern that the current 98th percentile form allows 7 exceedances per year and contend that a 99th percentile form that would allow half that number is more appropriate. Commenters also cite to the CASAC's advice in their review of the 2021 draft PA, which recommended that the EPA consider alternative percentiles for the form of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the future.

                        The EPA disagrees that the current 98th percentile form does not provide the requisite public health protection against peak PM
                        <E T="52">2.5</E>
                         exposures and concludes that the 98th percentile, averaged over three years, remains appropriate for the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. As noted in previous reviews and in the proposal, the EPA has set both an annual standard and a 24-hour standard to provide protection from health effects associated with both long- and short-term exposures to PM
                        <E T="52">2.5</E>
                         (62 FR 38667, July 18, 1997; 88 FR 5620, January 27, 2023). With respect to the form of the 24-hour standard, as described just above, the epidemiologic studies continue to provide strong support for health effect associations with short-term (
                        <E T="03">e.g.,</E>
                         mostly 24-hour) PM
                        <E T="52">2.5</E>
                         exposures and controlled human exposure studies provide evidence for health effects following single short-term “peak” PM
                        <E T="52">2.5</E>
                         exposures (88 FR 5619, January 27, 2023). Both the 98th and the 99th percentile form provide a very high degree of control of peak concentrations. As the commenters point out, a 99th percentile would reduce the number of allowable exceedances to four days per year. The EPA anticipates, however, that such a revision to the form would make the attainment status of an area more subject to change from unpredictable nonanthropogenic factors, such as meteorological events. The EPA has often noted that frequent shifts in attainment status that are unrelated to long-term air quality trends is inconsistent with providing a stable target for air quality planning and risk management programs, which in turn provides for the most effective public health protection in the long run (78 FR 3127, January 15, 2013; 80 FR 65351, October 26, 2015). Thus, the EPA's interest in an appropriate degree of stability is to ensure that the State air quality programs are effective in controlling pollution and that the public health protections of the standard are achieved. As discussed above, while recent controlled human exposure studies provide consistent evidence for cardiovascular effects following PM
                        <E T="52">2.5</E>
                          
                        <PRTPAGE P="16259"/>
                        exposures for less than 24 hours (
                        <E T="03">i.e.,</E>
                         &lt; 30 minutes to 5 hours), exposure concentrations in these studies are well-above the ambient concentrations typically measured in locations meeting the current standards (U.S. EPA, 2022a, section 3.3.3.1), and the 98th percentile form is very effective at limiting occurrences of exposures of concern. Taking into consideration the available scientific information and quantitative information, the EPA therefore concludes that the 98th percentile form provides an appropriate balance between limiting the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations and identifying a stable target for risk management programs. This conclusion is also supported by the advice given to the EPA by the CASAC in their review of the 2021 draft PA, where they reached consensus that the form for the standards should be retained, without revision (Sheppard, 2022a, p. 2 of consensus letter).

This advice is reflected in the proposal by the EPA, which noted “that it would be appropriate to gather additional air quality and scientific information and further consider these issues in future reviews” (88 FR 5619, January 27, 2023).

                         concentrations reported in key epidemiologic studies to inform conclusions on the level of the primary PM
                        <E T="52">2.5</E>
                         standard. These commenters argue that, in this reconsideration, the EPA is arbitrarily emphasizing uncertainties in key epidemiologic studies in the focus on mean concentrations. Many of these commenters recommend that the EPA consider the full distribution of PM
                        <E T="52">2.5</E>

                         standards, in particular concentrations below the mean, such as the 25th percentile. In supporting this view, commenters point to the CASAC's advice in their review of the 2021 draft PA, where the majority of the CASAC stated that the “use of the mean to define where the data provide the most evidence is conservative since robust data clearly indicate effects below the mean in concentration-response functions” (Sheppard, 2022a, p. 16 of consensus responses), and that “[e]pidemiologic studies require consideration of distribution around the mean of exposure to identify effects and thus lower levels than the mean must be considered as part of the range where the data provide higher confidence” (Sheppard, 2022a, p. 13 of consensus responses).

                         standard in section II.B.4 below, the EPA considers the long-term study-reported mean PM

                         concentrations from key epidemiologic studies and sets the level of the standard to somewhat below the lowest long-term mean PM

                         concentration. Additionally, as discussed further below, the EPA also considers the available information from a subset of epidemiologic studies that report exposure estimates or health events at the 25th and 10th percentiles of PM
                        <E T="52">2.5</E>
                         concentrations. The Administrator gives some weight to the 25th percentile data, although he recognizes that his confidence in the magnitude and significance in the reported concentrations, and their ability to inform decisions on the appropriate level of the annual standard, decreases with reduced data (below the mean) and diminishes further at percentiles that are even further below the mean and the 25th percentile. Therefore, the Administrator places weight on the reported 25th percentiles concentrations, rather than the reported 10th percentile concentrations, for the subset of studies that report lower percentile PM

These approaches were supported by the CASAC in previous reviews and were supported in this reconsideration by the CASAC in their review of the 2021 draft PA.

The Administrator also notes that, in their review of the 2019 draft PA, the CASAC lacked consensus on the inferences to be drawn from the epidemiologic evidence, with a majority of CASAC having concerns about confounding, error and bias and concluding that newer studies did not provide a basis for revising the current standards, while a minority concluded that the evidence, including more recent studies showing associations in areas with average long-term PM
                            <E T="52">2.5</E>
                             concentrations below the current annual standard, supported their conclusion that the current standards are inadequate (Cox, 2019b, pp. 8-9 of consensus responses).

                        In considering the available scientific evidence, the EPA notes the strength of the epidemiologic evidence which includes multiple studies that consistently report positive associations for short- and long-term PM

                         exposures and mortality and cardiovascular effects. Some available studies also use a variety of statistical methods to control for confounding bias and report similar associations, which further supports the broader body of epidemiologic evidence for both mortality and cardiovascular effects. Additionally, the EPA notes that recent epidemiologic studies strengthen support for health effect associations at PM
                        <E T="52">2.5</E>
                         concentrations lower than in those evaluated in epidemiologic studies available at the time of previous reviews.

                         concentrations and health outcomes, they do not identify the specific exposures that led to the reported effects. As such, there is no specific point in the air quality distribution of any epidemiologic study that represents a “bright line” at and above which effects have been observed and below which effects have not been observed.

                         exposures, most of the health events occur at estimated exposures that reflect annual average PM

                        Based on the air quality criteria for this reconsideration, as described in the 2019 ISA, ISA Supplement, 2022 PA and the proposal, the EPA believes it is appropriate to continue to use the mean PM

                    <P>The key U.S. epidemiologic studies that report percentiles below the mean that are monitor based are older studies. These studies included smaller numbers of people than the newer hybrid model-based studies. For the three older, monitor-based studies, because the cohorts were smaller in size, a relatively smaller portion of the health events were observed in the lower part of the air quality distribution. As such, our confidence in the magnitude and significance of the associations begins to decrease in the lower part of the air quality distribution of those older, monitor-based studies.</P>
                    <P>The three newer, hybrid model-based studies have larger cohort sizes than the older, monitor-based studies and, as noted by commenters, have more health events in the lower part of the air quality distribution. For these reasons, the EPA notes that we have more confidence in the reported association at concentrations lower than the reported mean in these more recent hybrid model-based studies, particularly at the 25th percentile compared to the 10th percentile. While the cohort sizes in the more recent, hybrid model-based studies are larger than the older, monitor-based studies, the EPA notes that the 10th percentiles are well below the middle portion of the air quality distribution for which we have the greatest confidence, and as noted above, our confidence in the magnitude and significance of associations in the lower parts of the air quality distribution begins to decrease. While we have more confidence in the lower percentiles because of the larger cohort sizes in the more recent hybrid model-based studies, we also have more confidence in the 25th percentiles than in the 10th percentiles, which are further from the means and closer to the lower end of the air quality distribution.</P>

The 25th percentiles from these studies, in particular those that are more recently available, help to inform the Administrator's judgments regarding the appropriate level for the primary annual PM

                        Some commenters disagree with the EPA's consideration of the relationship between mean PM

                         concentrations reported in the key epidemiologic studies and design values to inform conclusions on the appropriate level for the primary annual PM

                         standards. Commenters contend that setting the level of the primary annual standard below the design values in the epidemiologic studies, rather than below the study-reported mean concentrations, might keep overall mean PM
                        <E T="52">2.5</E>
                         concentrations throughout an area below the study-reported means but allow PM

                         concentrations in some parts of the area, including near the “design value monitor” to remain above the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, which are the concentrations where the evidence of health effects is strongest. Commenters contend that such a decision framework would not result in a standard that would provide requisite protection with an adequate margin of safety, 
                        <PRTPAGE P="16261"/>
                        particularly for at-risk populations. These commenters further support this view by citing the CASAC's advice in their review of the 2021 draft PA, where the majority of CASAC stated that “even if a design value is somewhat higher than the area average, it reflects actual exposure levels and thus any portion of the population living near the design value monitor does experience exposures at that level and consequent health effects of exposure to that higher concentration” (Sheppard, 2022a, p. 14 of consensus responses). Additionally, these commenters suggest that the EPA should not deviate from the approach taken in the 2012 review, which was to set the standard at a level “somewhat below” the lowest mean PM
                        <E T="52">2.5</E>
                         concentration in the key epidemiologic studies.

                        To the extent that commenters are suggesting that the EPA is setting the level of the primary annual PM

                         standard below the design values in the epidemiologic studies, rather than below the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, we disagree with the commenters. In reaching conclusions on the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard, the EPA considers the long-term study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations from key epidemiologic studies and sets the level of the standard to somewhat below the lowest long-term mean PM
                        <E T="52">2.5</E>
                         concentration, not below the design values in the epidemiologic studies. Additionally, the EPA also considers the available information from a subset of epidemiologic studies that report exposure estimates or health events at the 25th and 10th percentiles of PM
                        <E T="52">2.5</E>
                         concentrations. The EPA particularly considers the 25th percentile data, while recognizing that our confidence in the magnitude and significance in the reported concentrations, and the ability of the lower percentile PM
                        <E T="52">2.5</E>
                         concentrations to inform decisions on the appropriate level of the annual standard, decreases with reduced data (below the mean) and diminishes further at percentiles that are even further below the mean and the 25th percentile.

                    <P>
                        However, the EPA notes that it is important to understand, and to not ignore, the relationship between the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations reported in key epidemiologic studies and the area design value. As an initial matter, the NAAQS consists of all four elements of the standard (indicator, averaging time, form, and level) and setting a standard that is requisite to protect public health includes consideration of all four elements together. Following implementation of the NAAQS, the design value is the metric used to determine compliance with the standard and is the statistic that describes the air quality status of a given location relative to the level of the primary annual PM
                        <E T="52">2.5</E>
                         NAAQS. The design value is different from the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations. This is because the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations are an annual average PM
                        <E T="52">2.5</E>
                         concentration, similar to the level of the standard, but the epidemiologic studies do not report statistics that take into account the other elements of the standard (
                        <E T="03">i.e.,</E>
                         averaging time and form). Therefore, when considering the appropriate revisions to the annual PM
                        <E T="52">2.5</E>
                         standard, the EPA must consider the protection provided by a revised standard taking into account all of the elements of the standard, not just the annual average PM
                        <E T="52">2.5</E>
                         concentration alone.

                    <P>
                        In considering the annual standard, and in assessing the range of study-reported exposure concentrations for which we have the strongest support for adverse health effects observed in epidemiologic studies, the EPA focuses on whether the current primary annual PM
                        <E T="52">2.5</E>
                         standard provides adequate protection against these exposure concentrations or if the level of the standard should be revised to provide the appropriate public health protection. This means that, as in some previous reviews, it is important to consider how the study means were computed and how these concentrations compare to the annual standard metric (including the level, averaging time and form) which must be met at the monitor with the highest PM

                         design value in an area for compliance with the NAAQS. This approach is based on the application of a decision framework based on assessing means (as well as the lower distribution of reported PM
                        <E T="52">2.5</E>
                         concentration, as noted above) reported in key epidemiologic studies. In the 2012 review, the available key epidemiologic studies computed the mean PM
                        <E T="52">2.5</E>
                         concentrations using an average across monitor-based PM
                        <E T="52">2.5</E>
                         concentrations. As such, at that time, the decision framework used an approach based on maximum monitor concentrations to determine compliance with the standard, while selecting the standard level based on consideration of composite monitor concentrations (
                        <E T="03">i.e.,</E>
                         selecting the standard level of 12.0 µg/m
                        <SU>3</SU>
                         was just below the long-term study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations in key epidemiologic studies). Further, the EPA conducted analyses that examined the differences in these two metrics (
                        <E T="03">i.e.,</E>
                         maximum monitor concentrations, which is how compliance with the standard is assessed and composite monitor concentrations, which is how key epidemiologic studies report their mean concentrations) across the U.S. and in areas included in the key epidemiologic studies and found that the maximum design value in an area was generally higher than the monitor average across that area, with the amount of difference between the two metrics varying based on location and concentration (Hassett-Sipple et al., 2010; Frank, 2012). This information was taken into account by the then-Administrator's final decision in selecting a level of 12.0 µg/m
                        <SU>3</SU>

                         concentrations and the area design value continues to be an important consideration in evaluating the adequacy of the current or potential alternative annual standard levels in this reconsideration. Again, in a given area, the area design value is based on the monitor in an area with the highest PM

                         concentrations spatially distributed in the area would generally occur at or near the area design value monitor and the distribution of PM

                         a metric similar to the study-reported mean values) in that area to be at concentrations lower than that level (

                        However, as described in section II.A.2.c.ii, we note that there are a substantial number of different types of epidemiologic studies available since the 2012 review, as assessed in both the 2019 ISA and the ISA Supplement, that make understanding the relationship between the mean PM
                        <E T="52">2.5</E>
                         concentrations and the area design value an even more important consideration in this reconsideration (U.S. EPA, 2019a; U.S. EPA, 2022a). While the key epidemiologic studies in the 2012 review were all monitor-based studies, the recent epidemiologic studies in this reconsideration include hybrid modeling approaches that have emerged in the epidemiologic literature as an 
                        <PRTPAGE P="16262"/>
                        alternative to approaches that only use ground-based monitors to estimate PM
                        <E T="52">2.5</E>
                         exposure. As assessed in the 2019 ISA and ISA Supplement, a substantial number of epidemiologic studies used hybrid model-based methods in evaluating associations between PM
                        <E T="52">2.5</E>
                         exposure and health effects. Hybrid model-based studies employ various fusion techniques that combine ground-based monitored data with air quality modeled estimates and/or information from satellites to estimate PM
                        <E T="52">2.5</E>
                         exposures. While these studies provide a broader estimation of PM
                        <E T="52">2.5</E>
                         exposures compared to monitor-based studies (
                        <E T="03">i.e.,</E>
                         PM
                        <E T="52">2.5</E>
                         concentrations are estimated in areas without monitors), the hybrid modeling approaches result in study-reported means that are more difficult to relate to the annual standard metric and to the maximum monitor design values used to assess compliance. In addition, to further complicate the comparison, when looking across these studies, we find variations in how exposure is estimated between such studies, and thus, how the study means are calculated. Two important variations across studies include: (1) Variability in spatial scale used (
                        <E T="03">i.e.,</E>
                         averages computed across the national (or large portions of the country) versus a focus on only CBSAs); and (2) variability in exposure assignment methods (
                        <E T="03">i.e.,</E>
                         averaging across all grid cells, averaging across a scaled-up area like a ZIP code, and population weighting). The differences in these approaches can result in studies reporting different study means, even though the association between PM
                        <E T="52">2.5</E>
                         exposure and health effects outcomes are similar.
                    </P>
                    <P>
                        To emphasize the importance of the differences between the studies, we revisit the simplified example in the State of Georgia from the 2022 PA that evaluates monitors and hybrid modeling approaches, noting that this example is useful to exhibit how the differences in the methods used to estimate exposure can lead to differences in the reported mean concentrations (U.S. EPA, 2022b, p. 3-71). In this example, for all monitors within the Atlanta-Sandy Springs-Roswell CBSA, the average PM
                        <E T="52">2.5</E>
                         concentration is 9.3 µg/m
                        <SU>3</SU>
                        , while the area design value (based on the highest monitored PM
                        <E T="52">2.5</E>
                         concentration in the area) is 10.4 µg/m
                        <SU>3</SU>
                        . This comparison helps to illustrate the fact that composite monitor values tend to be somewhat lower than the highest area monitor values, consistent with the key points made in the 2012 review. This example also illustrates how monitors are sited to represent the higher concentrations within the area and that the area's annual design value, which is used for compliance with the standard, is calculated based on the highest monitor in the area. Next, in this example, mean PM
                        <E T="52">2.5</E>
                         concentrations were calculated using similar approaches to those used in hybrid modeling-based epidemiologic studies to compute study-reported means, including (1) the average concentration across the entire State of Georgia; (2) the population-weighted average across the entire State; (3) the average concentration across the Atlanta-Sandy Springs-Roswell CBSA; and (4) the population-weighted average across the Atlanta-Sandy Springs-Roswell CBSA. At the urban level (
                        <E T="03">e.g.,</E>
                         Atlanta-Sandy Springs-Roswell CBSA), the average PM
                        <E T="52">2.5</E>
                         concentration when taking the mean of all grid cells is 9.2 µg/m
                        <SU>3</SU>
                        , whereas the population-weighted mean is 9.6 µg/m
                        <SU>3</SU>
                        . Across Georgia, the average PM
                        <E T="52">2.5</E>
                         concentration using the hybrid approach and averaged across each grid cell is 8.3 µg/m
                        <SU>3</SU>
                        , which is lower than the population-weighted statewide average of 9.1 µg/m
                        <SU>3</SU>
                        . While this is a simple example completed in one State and one CBSA, it suggests that the lowest mean values tend to result from the approaches that use concentrations from all or most grid cells (
                        <E T="03">e.g.,</E>
                         did not apply population weighting), both urban and rural, across the study area to compute the mean. Higher mean values are observed when the approach focuses on the urban areas alone or when the approach incorporates population weighting. Overall, this example suggests that the means from studies using hybrid modeling approaches are generally lower than the means from monitor-based approaches, and means from both approaches are lower than the annual design values for the same area. Population weighting tends to increase the calculated mean concentration, likely because more densely populated areas also tend to have higher PM
                        <E T="52">2.5</E>
                         concentrations. In other words, this simplified example exhibits how not all reported mean PM
                        <E T="52">2.5</E>
                         concentrations from key epidemiologic studies are the same; some reported means are from monitored studies and some reported means are from hybrid modeling studies, while some reported means include only urban areas, and other reported means include both urban and rural areas, and some reported means include aspects of population weighting while others do not.

                    <P>
                        As detailed above in section I.D.5, in the air quality analyses comparing composite monitored PM
                        <E T="52">2.5</E>
                         concentrations with annual PM
                        <E T="52">2.5</E>
                         design values in U.S. CBSAs, maximum annual PM
                        <E T="52">2.5</E>
                         design values were approximately 10% to 20% higher than annual average composite monitor concentrations (
                        <E T="03">i.e.,</E>
                         averaged across multiple monitors in the same CBSA). Based on these results, this analysis suggests that there will be a distribution of concentrations and the maximum annual average monitored concentration in an area (at the design value monitor, used for compliance with the standard), will generally be 10-20% higher than the average across the other monitors in the area. Thus, in considering how the annual standard levels would relate to the study-reported means from monitor-based studies, we can generally conclude that an annual standard level that is no more than 10-20% higher than monitor-based study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations would generally maintain air quality exposures to be below those associated with the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, exposures for which we have the strongest support for adverse health effects occurring.
                    </P>
                    <P>
                        Air quality analyses described in section I.D.5 above also consider information from the epidemiologic studies that utilized the hybrid modeling approaches. Analyses show that average maximum annual design values are 40-50% higher when compared to annual average PM
                        <E T="52">2.5</E>
                         concentrations estimated without population weighting and are 15-18% higher when compared to average annual PM
                        <E T="52">2.5</E>
                         concentrations with population weighting applied. Given these results, it is worth noting that for the studies using the hybrid modeling approaches, the choice of methodology employed in calculating the study-reported means (
                        <E T="03">i.e.,</E>
                         using population weighting versus not applying aspects of population weighting), and not a difference in estimates of exposure in the study itself, can produce substantially different study-reported mean values, with the approach that does not employ population weighting producing a much lower reported mean PM
                        <E T="52">2.5</E>
                         concentration. Therefore, the impact of the differences in methods is an important consideration when comparing mean concentrations across studies.
                    </P>
                    <P>
                        Because of the differences in the methods employed by the key epidemiologic studies, and as demonstrated by the example and air quality analyses above, the application of any decision framework that considers the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, and evaluates whether the current annual standard provides adequate protection against these reported exposure concentrations, is more complicated than the 
                        <PRTPAGE P="16263"/>
                        approaches used in past reviews. As such, the EPA disagrees with commenters who argue that the EPA's consideration of the relationship between mean PM
                        <E T="52">2.5</E>
                         concentrations reported in key epidemiologic studies and design values is not appropriate and should be ignored.

                    <P>
                        In considering the information from the epidemiologic studies, while the EPA does not dispute the reported associations of epidemiologic studies in hybrid modeling studies that report long-term mean concentrations and do not apply aspects of population weighting, using the reported long-term mean concentration from these studies in informing an appropriate level of the annual PM
                        <E T="52">2.5</E>
                         standard is more uncertain. Given this, hybrid modeling studies that do not apply aspects of population weighting provide less information on conclusions regarding the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. In support of this, some commenters also noted this consideration and suggested that the Administrator place lower weight on U.S. studies that did not use population weighting.

                    <P>
                        In considering the relationship between study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and the design values, the EPA agrees with commenters that setting the level of the primary annual standard below the design values, rather than below the study-reported mean concentrations, might allow PM
                        <E T="52">2.5</E>
                         concentrations in some part of the area near the design value monitor to remain above the study-reported mean PM
                        <E T="52">2.5</E>
                        concentration, where evidence of health effects is strongest. As discussed in the proposal and in section II.B.4 below, the Administrator specifically notes that that the highest PM
                        <E T="52">2.5</E>
                         concentrations spatially distributed in the area would generally occur at or near the area design value monitor and that PM
                        <E T="52">2.5</E>
                         concentrations will be equal to or lower at other monitors in the area. Furthermore, since monitoring strategies aim to site monitors in areas with higher PM
                        <E T="52">2.5</E>
                         concentrations, monitored areas will generally have higher concentrations compared to areas without monitors. Therefore, by setting the level of the standard to 9.0 µg/m
                        <SU>3</SU>
                         and just below the lowest study-reported mean PM

                         concentration (

                        <SU>3</SU>
                        ), the highest possible design value in a given area would be just below the study-reported mean PM
                        <E T="52">2.5</E>
                         concentration, the concentration where we have the most confidence in the reported health effect association, and we anticipate that, based on our assessment of air quality data, the distribution of PM
                        <E T="52">2.5</E>
                         concentrations would decrease even further with distance from the highest monitor (
                        <E T="03">i.e.,</E>
                         the “design value monitor”) (see, for example, U.S. EPA, 2022a, section 2.3.3.2.4 and pp. 3-71 to 3-77). The Administrator further notes that when an epidemiologic study reports a mean PM
                        <E T="52">2.5</E>
                         concentration that reflects the average of annual average monitor-based concentrations across an area, the area design value will generally be higher than the study-reported mean. Similarly, he observes that when a study reports a mean that reflects the average of annual average concentrations estimated at across an area using a hybrid modeling approach, the area design value will generally be higher. As such, by evaluating the difference between the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and design values, the Administrator seeks to set the level of the standard below the lowest study-reported mean, while ensuring that the primary annual PM

                         standard, including its averaging time and form, provides protection against the exposures associated with health effects observed in the key epidemiologic studies.

                    <P>
                        Additionally, the EPA disagrees with commenters who contend that the approach taken may allow PM
                        <E T="52">2.5</E>
                         near the design value monitor to remain above the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations. In following this approach of setting the annual standard level somewhat below the lowest reported mean PM
                        <E T="52">2.5</E>
                         concentration, setting a standard level that requires the design value monitor (which is the highest monitor in an area) to be just below the lowest study-reported mean across key studies will generally result in distributions of even lower concentrations of PM
                        <E T="52">2.5</E>
                         across the entire area, such that even those people living near an area design value monitor (where PM
                        <E T="52">2.5</E>
                         concentrations are generally highest) will be exposed to PM
                        <E T="52">2.5</E>
                         concentrations below the PM
                        <E T="52">2.5</E>
                         concentrations reported in the epidemiologic studies where there is the highest confidence of an association. In their review of the 2021 draft PA, the majority of the CASAC had some concerns about the approach for comparing study means and design values, questioning whether such an approach would provide adequate protection for people who live in areas with higher concentrations, such as those living in areas with higher concentrations (
                        <E T="03">e.g.,</E>
                         near the design value monitor) (Sheppard, 2022a, p. 8 of consensus responses). The minority of the CASAC, in considering the relationship between the study-reported mean PM
                        <E T="52">2.5</E>
                         concentration and design values, stated that “the form of the standard and the way attainment with the standard is determined (
                        <E T="03">i.e.,</E>
                         highest design value in the CBSA) are important factors when determining the appropriate level for the standard” and noted that that design values are generally higher than area average exposure levels (Sheppard, 2022a, p. 17 of consensus responses). For all of the reasons discussed above, and consistent with the minority of the CASAC's advice in their review of the 2021 draft PA, we disagree with the commenters that areas near the design value monitors would be expected to experience PM
                        <E T="52">2.5</E>
                         concentrations above the study-reported mean concentrations.

                        Several commenters assert that epidemiologic studies that restrict PM
                        <E T="52">2.5</E>
                         concentration to below 12 µg/m
                        <SU>3</SU>
                         provide additional support for revising the level of the primary annual PM

                         standard to 8 µg/m
                        <SU>3</SU>
                        . Some commenters disagree with the EPA's assertion that the studies that employ restricted analyses do not provide enough information to understand how the studies were restricted to certain PM
                        <E T="52">2.5</E>
                         concentrations, with commenters providing additional information on the methods for restricted analyses. The commenters state that for the long-term studies at issue here, the study authors simply examined their database that linked subjects to long-term PM
                        <E T="52">2.5</E>
                         concentrations above 12 μg/m
                        <SU>3</SU>
                        , removed those data from the analysis, and reran the analysis. Additionally, one commenter provided an explanation of how the restricted analyses were conducted in studies for which he was an author. The commenter notes that for each year a subject was in the study, annual PM
                        <E T="52">2.5</E>
                         concentrations were assigned at the ZIP code level. If they moved, they were assigned the ZIP code level PM
                        <E T="52">2.5</E>
                         concentration for the new ZIP code. The commenter notes that these restricted analyses only included subjects whose annual PM
                        <E T="52">2.5</E>
                         exposure never exceeded that restricted concentration for any year of follow-up in the study. The commenter suggested that the EPA may be concerned as to how PM
                        <E T="52">2.5</E>
                         concentrations in restricted analyses related to a design value since these are exposures for individuals who may have relocated during the study but argue that that is not the point. The commenters assert that while the analyses were restricted to people never exposed above certain concentrations over longer periods of time, the actual PM
                        <E T="52">2.5</E>
                         exposure was one year of exposure in most of these studies. Commenters also suggest that, since the 
                        <PRTPAGE P="16264"/>
                        EPA has deviated from its approach from the 2012 review for considering study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations, the EPA should dismiss its concerns regarding being able to relate the mean PM
                        <E T="52">2.5</E>
                         concentrations from these studies to design values.
                    </P>
                    <P>
                        First, the EPA agrees with commenters that studies that employ restricted analyses can be used for informing conclusions regarding the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. However, the EPA disagrees that the information provided by the commenters provides a sufficient basis for an annual standard level of 8 μg/m
                        <SU>3</SU>
                        . Restricted analyses provide additional support for effects at lower concentrations, exhibiting associations for mean concentrations presumably below the mean concentrations for the main analyses. However, even though commenters note that any individual with exposures over the restricted analyses is excluded from restricted analyses, uncertainties remain with regard to how the mean PM
                        <E T="52">2.5</E>
                         concentrations in restricted analyses compare to design values, particularly in light of the removal of entire ZIP codes from analyses. Design values are calculated based on all measured PM
                        <E T="52">2.5</E>
                         concentrations. When an analysis is restricted below a certain level, some parts of the air quality distribution are removed, but comparing the restricted mean to a design value is not possible because these are two different metrics. For example, in a study that restricts concentrations below 12 µg/m
                        <SU>3</SU>
                        , that represents only part of the air quality distribution, whereas a design value for that study area would include all PM
                        <E T="52">2.5</E>
                         concentrations, not just the ones below 12 µg/m
                        <SU>3</SU>
                        . Therefore, in contrast to means from the main (unrestricted) analysis, it is not possible to compare mean concentrations from restricted analyses to design values. Further, it is unclear how one could evaluate such a relationship between design values and mean PM
                        <E T="52">2.5</E>
                         concentrations from studies that use restricted analyses because the standard is set based on all of its elements (indicator, averaging time, form, and level) and removing PM
                        <E T="52">2.5</E>
                         concentrations from the calculation of the design value for such a comparison would result in a metric that is no longer a design value that would provide the intended protection of the standard. This leads to greater uncertainty in how to use the mean PM
                        <E T="52">2.5</E>
                         concentrations from these studies that use restricted analyses in a similar decision framework as the epidemiologic studies that report long-term mean PM
                        <E T="52">2.5</E>
                         concentrations for health effect associations for the full distribution of PM
                        <E T="52">2.5</E>
                         concentrations.

                    <P>
                        As described in reaching his conclusions in the section below, the Administrator judges that, despite these uncertainties and limitations, studies that use restricted analyses can provide supplemental information for consideration in reaching conclusions regarding both the adequacy and level of the standard. He notes two studies (Di et al., 2017b and Dominici et al., 2019) are available in this reconsideration that report means in their restricted analyses (restricting annual average PM
                        <E T="52">2.5</E>
                         exposure below 12 μg/m
                        <SU>3</SU>
                        ) and used population-weighted approaches to estimate PM
                        <E T="52">2.5</E>
                         exposures and these studies report mean PM
                        <E T="52">2.5</E>
                         concentrations of 9.6 µg/m
                        <SU>3</SU>
                        . He recognizes that these studies are just one line of evidence for consideration and that along with the broader evidence base, including the key epidemiologic studies, these studies provide support that the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard should be set below 10 µg/m
                        <SU>3</SU>
                        .

                    <P>
                        We disagree with the commenters that concerns about relating the mean PM
                        <E T="52">2.5</E>
                         concentrations from restricted analyses to design values are not valid. As an initial matter, restricted analyses were not available and did not inform the 2012 decision to revise the annual PM
                        <E T="52">2.5</E>
                         standard level to 12.0 µg/m
                        <SU>3</SU>
                        . The approach in 2012 in revising the annual standard was to set the level to somewhat below the mean of key epidemiologic studies. As noted above, while the EPA believes that restricted analyses can help inform conclusions regarding the adequacy and the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard, in the context of placing the studies in a decision framework to inform the appropriate level of the annual PM
                        <E T="52">2.5</E>
                         standard, the EPA has not deviated from its approach from the 2012 review. Given that restricted analyses are new since the 2012 review, the EPA disagrees with commenters that uncertainties associated with these studies should not be considered, and that these studies should be used in a similar manner to their main analyses in taking an approach to set a level of the standard somewhat below the lowest long-term reported mean PM
                        <E T="52">2.5</E>
                         concentration. Specifically, as detailed above there are uncertainties and limitations associated with relating the mean PM
                        <E T="52">2.5</E>
                         concentrations from these studies to design values for studies that use restricted analyses, and many of these studies did not expressly report a mean PM
                        <E T="52">2.5</E>
                         concentration for the restricted analysis which makes it impossible to make such a comparison.

                        Several commenters contend that in considering the accountability studies, the EPA inappropriately reached conclusions regarding the level of the primary annual PM

                        Accountability studies examine the effect of a policy on reducing PM

                         concentrations in ambient air and evaluate whether such reductions were observed to also lead to reductions in PM

Prior to implementation of the policies, three accountability studies newly available in this reconsideration and assessed in the ISA Supplement, report mean PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current annual standard level (12.0 µg/m
                        <SU>3</SU>
                        ) and ranged from 10.0 µg/m
                        <SU>3</SU>
                         to 11.1 µg/m
                        <SU>3</SU>
                         (Sanders et al., 2020b; Corrigan et al., 2018; and Henneman et al., 2019). These studies suggest that public health improvements may occur following the implementation of a policy that reduces annual average PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current standard of 12.0 µg/m
                        <SU>3</SU>
                        , and potentially below the lowest “starting” concentrations in these studies of 10.0 µg/m
                        <SU>3</SU>
                        . However, while the small number of studies may provide limited information related to informing the adequacy and level of the annual PM
                        <E T="52">2.5</E>
                         standard, we note that accountability studies are only one line of evidence, and that these studies provide supplemental information for consideration in addition to the full body of evidence. Further, the EPA does not believe it would be appropriate to determine the level of the standard by reference to ending concentrations in accountability studies. Accountability studies are most informative in demonstrating that public health improvements may occur following the implementation of a policy that reduces annual average PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current standard of 12.0 µg/m
                        <SU>3</SU>
                        , and potentially below the lowest “starting” concentrations in these studies of 10.0 µg/m
                        <SU>3</SU>
                        . However, the EPA finds the available information from accountability studies is too limited to support a conclusion that the 
                        <PRTPAGE P="16265"/>
                        appropriate level at which to set the primary annual PM

                         standard would be equal to the ending concentrations of those studies, as the commenters suggest. These studies demonstrate that there are reductions in health outcomes when PM
                        <E T="52">2.5</E>
                         concentrations are reduced in these studies from the starting concentration to the ending concentration, but do not provide support for health effect associations at or below the ending concentrations that would warrant a more stringent standard.

                        Commenters disagree with the Administrator placing less weight on the epidemiologic studies conducted in Canada when reaching conclusions regarding the level of the primary annual PM

                         standard. These commenters argue that the Canadian epidemiologic studies provide support for setting the level at the lowest end of the proposed range (

                        <E T="52">2.5</E>
                         standard. Additionally, while the commenters disagree with the EPA's approach for considering the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and design values in general, they note that the CASAC, in their review of the 2021 PA, noted that “while there may be no design value in Canada, there are data that indicate what a U.S. design value would be if an area average like that found in the Canadian studies were to occur in the U.S.” (Sheppard, 2022a, p. 13 of consensus responses). The commenters contend that the EPA failed to acknowledge this advice from the CASAC, specifically noting that the majority of the CASAC highlighted Canadian epidemiologic studies as a part of their rationale for revising the level of the primary annual PM
                        <E T="52">2.5</E>

                        In considering the information from the epidemiologic studies in reaching his conclusions, the Administrator considered the full body of evidence, including studies conducted in the U.S. and Canada. However, as described in the proposal and in section II.B.4 below, the Administrator also recognizes that the exposure environments in the U.S. are different from those in Canada. In particular, the U.S. population density is approximately 43 people per square kilometer in the contiguous U.S.
                        <SU>98</SU>
                        <FTREF/>
                         compared to Canada, which has one of the lowest population densities on the Earth with 4.2 people per square kilometer (Statistics Canada, 2023). This difference in population density between the U.S. and Canada was not as apparent, and did not need to be highlighted, in the 2012 review given that the available Canadian epidemiologic studies used population-weighting and focused on urban areas where monitors were available and population densities were more comparable with those in the U.S. Given this, the study-reported mean concentrations from U.S. and Canadian studies in the 2012 review were very similar. The recent epidemiologic evidence available in this reconsideration, however, includes studies that utilize approaches that highlight the importance of considering the differences between the two exposure environments in the U.S. versus Canada. When focusing on the recently available Canadian monitor-based epidemiologic studies in this reconsideration, the information indicates that these studies, unlike the studies available in the 2012 review, do not apply population weighting (
                        <E T="03">e.g.,</E>
                         Lavigne et al., 2018; Liu et al., 2019). As noted in responding to other public comments above, the absence of population weighting is an important consideration that limits the utility of these studies in informing the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. In addition, there are recently available studies in the 2019 ISA and ISA Supplement that expand the geographical extent of the epidemiologic study areas by estimating exposure concentrations in areas where there are no monitors. To do this, these studies use either a statistical extrapolation of monitored values or use air quality modeling and other forms of data (
                        <E T="03">e.g.,</E>
                         hybrid model-based approaches). For these Canadian studies, the EPA notes two important considerations in using the information to directly translate to policy decisions regarding the level of the annual standard in the U.S. The first is that in incorporating a larger portion of Canada into these recent studies, more rural areas are included, and as such, the population densities and exposure environment differences become more important. The second is that in analyses that evaluate and validate hybrid models, there is less certainty in PM
                        <E T="52">2.5</E>
                         exposure estimates in more rural areas, which are further from air quality monitors and where PM
                        <E T="52">2.5</E>
                         concentrations in the ambient air tend to be lower (U.S. EPA, 2022b, pp. 2-51 and 2-63). Additionally, it is unclear what portion of the PM
                        <E T="52">2.5</E>
                         concentrations from rural areas are contributing to the study reported mean. Given this, studies that incorporate more rural areas into the epidemiologic studies highlight the importance of considering the differences between the population exposures in the studies themselves and in the U.S. versus Canadian study areas, as well as the influence these differences have on the interpretation of the epidemiologic study results. For these reasons, while the Canadian epidemiologic studies provide additional support for associations between PM
                        <E T="52">2.5</E>
                         concentrations and health effects, the long-term means from Canadian epidemiologic studies are a less certain basis for informing the EPA's selection of the annual standard level, given that it is a U.S.-based standard.

                        With respect to the CASAC's advice in their review of the 2021 draft PA, the EPA recognizes that the majority of the CASAC pointed to the Canadian studies as supporting their recommendation to revise the annual standard level to within the range of 8-10 µg/m
                        <SU>3</SU>
                        . However, the EPA also notes that the CASAC did not advise the EPA to revise the annual standard to a level that was below the study-reported means in the key Canadian epidemiologic studies. Indeed, the CASAC noted that some of the Canadian studies showed associations below 8 µg/m
                        <SU>3</SU>
                        , but did not recommend that the Administrator consider levels below 8 µg/m
                        <SU>3</SU>
                         for the annual standard. Further, based on the CASAC's advice, the Administrator is not excluding Canadian studies from his consideration in this reconsideration, but he is considering them in light of the limitations and challenges presented and in the context of the full body of available scientific evidence.

                    <P>
                        Lastly, the EPA disagrees with commenters that the findings of the Canadian epidemiologic studies can be directly translated into a primary annual PM
                        <E T="52">2.5</E>
                         standard based on the evaluation of the relationship between U.S. study-reported mean PM

                         concentrations and U.S. design values. It is unclear whether the relationship between U.S. study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations and U.S. design values (which, in the case of U.S. hybrid model-based studies, indicates that design values are 15-18% greater than area mean PM
                        <E T="52">2.5</E>
                         concentrations) would apply to the Canadian epidemiologic studies and their reported mean PM

                        <PRTPAGE P="16266"/>
                        concentrations, given that these studies generally report lower PM
                        <E T="52">2.5</E>
                         concentrations than the U.S.-based studies. As such, interpreting the study-reported mean concentrations from the Canadian studies in the context of a U.S.-based standard may present challenges in directly and quantitatively informing decisions regarding potential alternative levels of the annual standard, particularly noting the different in exposure relationships in the U.S. versus Canada given the large difference in population densities between the two countries. Further, as mentioned above, while the CASAC advised the EPA to consider the Canadian studies as relevant evidence and found that placing weight on the Canadian studies supported their recommendation to revise the annual standard level to within the range of 8-10 µg/m
                        <SU>3</SU>
                        , the lower end of their recommended range for the level of the annual standard did not extend below the lower study-reported means from those studies.

                         standard both raised concerns regarding how the EPA used the scientific evidence and quantitative risk assessment related to disparities in PM

                         exposure and risk in informing conclusions on the standard. Commenters who supported retaining the standard assert that the available scientific evidence that demonstrates disparities for minority populations do not support revising the standard, noting that these studies are in areas that tend to have large minority populations and more sources of PM. These commenters contend that because the studies conclude that minority populations experience more effects than others living in the same area that something other than PM
                        <E T="52">2.5</E>
                         concentrations in ambient air is causing the disproportionate impact on minority populations, providing proximity to a source as an example. The commenters note that it is unclear how a national standard will reduce exposure disparities for population groups living in the same area, and further assert that studies of exposure disparities among minority populations were considered in reaching the 2020 final decision to retain the standards.

                        <SU>3</SU>
                        , disparities in exposure are significantly reduced for an alternative standard level of 8.0 μg/m

                        As discussed in section I above, the primary (health-based) NAAQS are established at a level that is requisite to protect public health, including the health of sensitive or at-risk groups, with an adequate margin of safety.

                         In so doing, decisions on the NAAQS are based on an explicit and comprehensive assessment of the current scientific evidence and associated risk analyses. More specifically, the EPA expressly considers the available information regarding health effects among at-risk populations in decisions on the primary NAAQS. Where populations with disparities in exposure and risk are among the at-risk populations, the decision on the standards is based on providing requisite protection for these and other at-risk populations and lifestages.

                        With respect to the risk assessment, while the EPA notes that the analyses support the conclusion that the primary PM

                         standards are not adequate, as detailed further in the proposal and above in section II.A.3, the EPA also cautions against an over-interpretation of the absolute results. The quantitative risk assessment provides estimates of PM

                         concentrations to meet lower alternative standard levels. As a result, simulated air quality improvements used in the risk assessment will always lead to proportional decreases in risk (

                        The same is true for the new at-risk analysis in the risk assessment presented in the 2022 PA that is based on a recent epidemiologic study that is available in this reconsideration that provides mortality risk coefficients for older adults (
                        <E T="03">i.e.,</E>
                         65 years and older) based on PM

                         exposure and stratified by racial and ethnic demographics. Generally, the results of at-risk analyses can vary greatly depending on the inputs to the analyses, including the representativeness of the populations and demographics captured by the study areas that are a part of the analyses, as well as the available C-R functions from epidemiologic studies that stratify by race and ethnicity and the air quality adjustment approaches that are used to simulate air quality at different standard levels. In fact, for this at-risk analysis, the results are even more uncertain than similar estimates from the overall risk assessment due to additional sources of uncertainty specific to the at-risk analysis, such as using C-R functions derived from smaller epidemiologic sample sizes along with the sources of uncertainty that apply to the overall risk assessment (U.S. EPA, 2022b, section 3.4.1.8). Additionally, in characterizing at-risk populations, the at-risk analysis only used one of the air quality adjustment approaches used in the overall risk assessment, which decreases the potential representativeness of the PM
                        <E T="52">2.5</E>
                         concentrations across the study areas (U.S. EPA, 2022b, section 3.4.1.8). Lastly, this at-risk analysis relies on the stratified risk coefficients from only one epidemiologic study.

                        While there are substantial uncertainties in the absolute results of the quantitative risk assessment, the EPA also notes that recent scientific evidence evaluated in the ISA Supplement, which built upon the 2019 PM ISA conclusions, found that the evidence “[c]ontinue[s] to support disparities in PM
                        <E T="52">2.5</E>
                         exposure and health risks by race and ethnicity” while studies of SES “provide additional support indicating there may be disparities in PM
                        <E T="52">2.5</E>
                         exposure and health risk by SES” (U.S. EPA, 2022a, p. 5-4). Thus, in light of the statutory requirement to provide protection for at-risk populations, it is not surprising that the stratified population results of the risk assessment suggest that meeting a revised standard would result in higher risk reductions for minority and low SES populations.
                    </P>
                    <P>
                        In conclusion, the EPA recognizes that the at-risk analysis was based on one epidemiologic study that stratified by race/ethnicity for older adults (
                        <E T="03">e.g.,</E>
                         65+ years old) and that there is increasing uncertainty in quantitative estimates of stratified risk estimates at the lower end of the range of standard levels assessed. Moreover, the EPA finds that the goal of the NAAQS is to provide the requisite protection to at-risk groups, and where minority populations are included among the at-risk groups, providing requisite protection to minority populations will also result in protecting the public health of other populations. Thus, in setting the NAAQS to protect the health of at-risk groups with an adequate margin of safety, the Administrator is selecting the standard that will provide requisite protection, including for minority populations and other at-risk populations, which also generally results in protecting the public health of other populations and reducing risk disparities.

                         standards work together to provide public health protection, with the 98th percentile form of the 24-hour standard effectively limiting peak daily concentrations. The commenters agree with the EPA that the current suite of standards maintain subdaily concentrations below the higher concentrations in controlled human exposure studies where more consistent health effects are observed. Commenters also agree with the EPA's conclusions that the epidemiologic studies are not useful for informing decisions on the level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard because the standard focuses on reducing peak exposures with its 98th percentile form, while the epidemiologic studies often focus on the mean or median as the percentile for which associations with short-term exposures are observed. These commenters also agree with the EPA's focus on U.S.-based studies because of differences compared to Canadian studies. The commenters also generally agree with the Administrator's judgment that it was appropriate to place less weight on the risk assessment, noting that the annual standard is controlling in most areas of the country and revising the annual standard would have the most potential to reduce risk related to PM
                        <E T="52">2.5</E>
                         exposures and would reduce both average (annual) and peak (daily) PM
                        <E T="52">2.5</E>
                         concentrations. Finally, these commenters note that the CASAC did not reach consensus on whether the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard should be revised, and they agree with the minority of the CASAC's recommendation in their review of the 2021 draft PA that the primary 24-hour primary PM
                        <E T="52">2.5</E>
                         standard should be retained. These commenters also note the CASAC's support in their review of the 2019 draft PA for retaining the primary 24-hour PM
                        <E T="52">2.5</E>

                        A number of commenters, primarily from public health and environmental organizations and some States, oppose the EPA's proposed decision to retain the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. These commenters support revising the level of the primary 24-hour PM

                         standard, contending that a more stringent standard is necessary to provide requisite public health protection with an adequate margin of safety, particularly for at-risk groups. In so doing, these commenters place weight on the same aspects of the available scientific evidence as the majority of the CASAC in their review of the 2021 draft PA, and generally advocate for revising the level of the standard to within the range of 25-30 µg/m
                        <SU>3</SU>
                         as recommended by the majority of the CASAC. Some of these commenters support a level no higher than 25 µg/m
                        <SU>3</SU>
                         and others support a level of 20 µg/m
                        <SU>3</SU>
                        . These commenters generally cite to the available scientific evidence, including evidence of disproportionate exposures and risks for certain at-risk groups, and the CASAC's advice in support for their recommendation. Some of these commenters also suggest that decisions regarding the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard should not be related to decisions on the primary annual PM

                        As an initial matter, the EPA disagrees with commenters who suggest that decisions regarding the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard should not be related to decisions on the primary annual PM
                        <E T="52">2.5</E>
                         standard. In reviewing the adequacy of the public health protection afforded by the primary PM
                        <E T="52">2.5</E>
                         standards, the Administrator's consistent past practice has been to evaluate the combination of the annual and 24-hour standards together. In 2012, the then-Administrator concluded that the most effective and efficient way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures was to set a generally controlling annual standard, and to provide supplemental protection by means of a 24-hour standard set at the appropriate level. In so doing, the then-Administrator explicitly recognized that potential air quality changes associated with meeting a revised annual standard (with a level of 12 µg/m
                        <SU>3</SU>
                        ) would result in lowering risks associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures by lowering the overall distribution of air quality concentrations, and that retaining a 24-hour standard at the appropriate level would ensure an adequate margin of safety against short-term effects in areas with high peak-to-mean ratios (78 FR 3163, January 15, 2013). In this reconsideration, also, the Administrator considers it appropriate to rely on the annual standard (arithmetic mean, averaged over three years) for targeting protection against both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures, noting that the annual standard is typically controlling, while the 24-hour standard (98th percentile, averaged over three years) can provide supplemental protection against the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations (U.S. EPA, 2022b, section 3.6.3). Further, the Administrator notes that, as in the 2012 review, changes in PM
                        <E T="52">2.5</E>
                         air quality to meet a revised annual standard would 
                        <PRTPAGE P="16268"/>
                        affect the entire distribution of long- and short-term concentrations, thus likely resulting not only in lower short- and long-term PM
                        <E T="52">2.5</E>
                         concentrations near the middle of the air quality distribution, but also in fewer and lower short-term peak PM
                        <E T="52">2.5</E>
                         concentrations.
                        <SU>101</SU>
                        <FTREF/>
                         Thus, the Administrator continues to conclude it is appropriate to consider whether the annual and 24-hour standards together provide requisite protection of public health, rather than considering each standard in isolation.

                             Similarly, the Administrator recognizes that changes in air quality to meet a 24-hour standard, would result not only in fewer and lower peak 24-hour PM
                            <E T="52">2.5</E>
                             concentrations, but also in lower annual average PM
                            <E T="52">2.5</E>
                             concentrations. However, as noted in 2012, an approach that relied on setting the level of the 24-hour standard such that the 24-hour standard was generally controlling would be less effective and result in less uniform protection across the U.S. than an approach that focuses on setting a generally controlling annual standard (78 FR 3163, January 15, 2013).

                        Regarding the appropriate basis for determining the level of the 24-hour standard, a number of commenters who support revising the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard to a lower level contend that the EPA should not rely on the controlled human exposure studies in evaluating the adequacy of the public health protection afforded by the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. These commenters support this view by citing the CASAC comments in their review of the 2019 draft PA which advised that controlled human exposure studies have limitations that may impact their ability to inform conclusions on the adequacy of the public health protection afforded by the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. Commenters noted that these studies do not include the most vulnerable populations and often involve exposure to only one pollutant to elicit a response, and therefore are not representative of real-world exposures.

                    <P>
                        Other commenters support the EPA's use of the controlled human exposure studies to inform the adequacy of the public health protection and note that the 24-hour standard must at least provide protection against the health effects observed in controlled human exposure studies. Some of the commenters cite the Wyatt et al. (2020) study that demonstrated cardiovascular effects following 2-hour exposures to 120 µg/m
                        <SU>3</SU>
                         and 4-hour exposures to 37.8 µg/m
                        <SU>3</SU>
                        . Some of these commenters contend that the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard allows PM
                        <E T="52">2.5</E>
                         exposures comparable to those observed to elicit effects in the controlled human exposure studies, and therefore, the EPA must revise the level of the current standard to protect public health. To support this view, some commenters submitted an analysis of monitoring data from 2017-2020, which compares the number of days per year where maximum daily PM
                        <E T="52">2.5</E>
                         concentrations exceed 120 µg/m

                        Additionally, other commenters assert that the EPA should focus less on peak PM
                        <E T="52">2.5</E>
                         concentrations “typically measured” in areas meeting the current primary PM
                        <E T="52">2.5</E>
                         standards even if they do not exceed the concentrations in the controlled human exposure studies because, in their view, the standard needs to protect against atypical exposures to atypical peak PM
                        <E T="52">2.5</E>
                         concentrations. These commenters conclude that, when considered together, the controlled human exposure studies and the epidemiologic studies warrant strengthening the level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard.

                        The EPA generally disagrees with commenters who contend that it is inappropriate to rely on the controlled human exposures studies in evaluating the adequacy of the public health protection afforded by the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. The Agency considers these studies informative both for establishing biological plausibility and for determining an appropriate level for the 24-hour standard. When looking to the experimental studies, the EPA finds that the 2019 ISA and ISA Supplement included controlled human exposure studies that report statistically significant effects on one or more indicators of cardiovascular function following 2-hour exposures to PM
                        <E T="52">2.5</E>
                         concentrations at and above 120 μg/m
                        <SU>3</SU>
                         (and at and above 149 μg/m
                        <SU>3</SU>
                         for vascular impairment, the effect shown to be most consistent across studies). As noted in the 2019 ISA, these studies are important in establishing biological plausibility for PM
                        <E T="52">2.5</E>
                         exposures causing more serious health effects, such as those seen in short-term exposure epidemiologic studies, and they provide support that more adverse effects may be experienced following longer exposure durations and/or exposure to higher concentrations. Additionally, one controlled human exposure study assessed in the ISA Supplement reports evidence of some effects for cardiovascular markers at lower PM
                        <E T="52">2.5</E>
                         concentrations, 4-hour exposures to 37.8 µg/m

                         (Wyatt et al., 2020). However, there is inconsistent evidence for inflammation in other controlled human exposure studies evaluated in the 2019 ISA. The EPA notes that although the controlled human exposure studies do not provide a threshold below which no effects occur, the observed effects in these controlled human exposures studies are ones that signal an intermediate effect in the body, likely due to short-term exposure to PM
                        <E T="52">2.5</E>
                        , and typically would not, by themselves, be judged as adverse (88 FR 5620, January 27, 2023)

                        <PRTPAGE P="16269"/>
                        studies are therefore somewhat limited in their ability to inform at what concentrations effects may be elicited in at-risk populations. In spite of this limitation, the EPA also agrees with the CASAC, that even taking into consideration the limitations of the controlled human exposure studies, these studies can provide some support for evaluating the adequacy of the 24-hour standard. However, the EPA further notes that while the controlled human exposure studies are important in establishing biological plausibility, the health outcomes observed in these controlled human exposure studies are often “intermediate” outcomes (

                         not always clearly adverse) and therefore it is unclear how the importance of the effects observed in the studies should be interpreted with respect to adversity to public health. The EPA finds that it is appropriate to consider these study limitations in assessing the information provided by controlled human exposure studies in evaluating the adequacy of the primary 24-hour PM

                        <E T="52">2.5</E>
                         in the controlled human exposure studies occur under recent air quality conditions in areas meeting the current standards. Based on these air quality analyses, the EPA concludes that these types of exposures very rarely occur when the current standards are being met.

                        The EPA did receive multiple comments questioning these results and the approach in the EPA's analyses. For example, some commenters submitted an analysis of monitoring data from 2017-2020, which compares the number of days per year where maximum daily PM
                        <E T="52">2.5</E>
                         concentrations exceed 120 µg/m

                        First, the EPA notes that this analysis submitted by commenters was limited to a very small number of monitors and did not include a national perspective. Second, the EPA notes that this analysis focused on number of days (rather than the number of times) where there was a 2-hour maximum concentration over 120 µg/m
                        <SU>3</SU>
                         or a 4-hour max concentration over 37.8 µg/m

                        <SU>3</SU>
                         and 4-hour concentrations greater than 37.8 µg/m
                        <SU>3</SU>
                        , the EPA considers it more informative and appropriate from a public health perspective to assess the number of times a subdaily exposure of concern occurs in a year, rather than the number of days on which they occur because the former identifies more potential exposures of concern and provides more information about the scale and scope of the occurrences of those exposures. Lastly, the analyses allowed monitors somewhat above the standards to be included. Therefore, it is unclear whether the exceedances of the 2-hour or 4-hour benchmarks would still have occurred if the area had actually been meeting the current primary PM
                        <E T="52">2.5</E>

                        In evaluating the results from the new analyses, it is important to keep in mind that the 2019 ISA and ISA Supplement concluded that the most consistent evidence from the controlled human exposures studies is for impaired vascular function following 2-hour exposures to average PM
                        <E T="52">2.5</E>
                         concentrations at and above about 120 µg/m
                        <SU>3</SU>
                        , with less consistent evidence for effects following exposures to concentrations lower than 120 µg/m
                        <SU>3</SU>
                        . The new analyses show that across all monitors, on average, only 0.029 percent of 2-hour observations reach PM
                        <E T="52">2.5</E>
                         concentrations higher than 120 µg/m

                        . Further, recognizing that one purpose of the 24-hour standard is to protect against exposure in areas with high peak-to-mean ratios, when assessing the monitors individually across the U.S. under these same conditions, the monitors reporting the highest PM
                        <E T="52">2.5</E>

                        Additionally, the analyses also evaluated the frequency of reporting a 4-hour maximum concentration over 37.8 µg/m
                        <SU>3</SU>
                         when monitors were meeting the current 24-hour standard and a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                        . For this part of the analysis, the EPA finds that across all monitors, on average, only 0.41 percent of 4-hour observations reach PM
                        <E T="52">2.5</E>
                         concentrations higher than 37.8 µg/m

                        . Further, when assessing the monitors individually across the U.S. under these same conditions, the monitors reporting the highest PM
                        <E T="52">2.5</E>
                         concentrations have only 2.6 percent of 4-hour observations reach PM
                        <E T="52">2.5</E>
                         concentrations higher than 37.8 µg/m
                        <SU>3</SU>
                        . Thus, the EPA disagrees with commenters that the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard typically allows PM

                         exposures at or above those observed to cause health effects in controlled human exposure studies. Furthermore, the EPA notes that in light of the small number of occurrences and the intermediate nature of the effects observed in Wyatt et al. (2020) at concentrations of 37.8 µg/m
                        <SU>3</SU>

                         effects that typically would not, by themselves, be judged as adverse), there is substantial basis to doubt whether further improvements in public health 
                        <PRTPAGE P="16270"/>
                        would be achieved by further reducing these exposures. In drawing this conclusion, the EPA notes the lack of evidence of effects from controlled human exposure studies at levels below the current 24-hour standard and the fact that the results of Wyatt et al. (2020) are inconsistent with other currently available studies, and this study only observes intermediate effects.

                        In response to commenters that cited the majority of the CASAC's view that, in general, “[t]here is . . . less confidence that the annual standard could adequately protect against health effects of short-term exposures” (Sheppard, 2022a, p. 4 of consensus letter), the EPA disagrees with the majority of CASAC, noting that the results of the EPA's analysis suggest that high peak concentrations are extremely infrequent in areas meeting an annual standard of 9.0 µg/m
                        <SU>3</SU>
                        , occurring less than 0.029-0.41 percent of the time (for 2-hour concentrations &gt;120 µg/m
                        <SU>3</SU>
                         and 4-hour concentrations &gt;37.8 µg/m
                        <SU>3</SU>
                        , respectively). This suggests that in most locations, even the upper tail of the distribution would be controlled quite well under a revised annual standard. With regard to the likelihood that the current standards would allow peak concentrations that are clearly of concern from a health perspective, therefore, the EPA concludes that such occurrences are extremely infrequent—and will be even less frequent under the improved air quality conditions associated with meeting a revised annual PM

                         standard to a lower level suggest that the available epidemiologic evidence provides support for such a revision. To support their view, the commenters note that the currently available evidence, including a number of epidemiologic studies that demonstrate associations between short-term PM

                         exposures and health effects as described in the 2019 ISA and ISA Supplement. The commenters further note that the available epidemiologic studies include diverse populations that are broadly representative of the U.S. population, including at-risk populations, which they assert is an advantage over the controlled human exposure studies and the risk assessment, which are not as broadly representative.

                    <P>
                        These commenters highlight a number of specific epidemiologic studies that they suggest provide support for revising the level of the 24-hour standard. Additionally, commenters contend that there are epidemiologic studies using restricted analyses that show that positive and statistically significant associations between short-term PM
                        <E T="52">2.5</E>
                         exposure and mortality persist at daily mean concentrations below 25 µg/m
                        <SU>3</SU>
                        . The commenters also cite several studies that provide no evidence of a threshold. These commenters also point to the CASAC advice in their review of the 2021 draft PA, where the majority of the CASAC cited epidemiologic studies using restricted analyses as offering support for revision. The commenters argue that the EPA cannot base discretion on uncertainties related to the methods used in restricted analyses in the epidemiologic studies. In so doing, these commenters disagree with the EPA that it is important to take into consideration that these studies do not consider the form or averaging time of the 24-hour standard. Finally, the commenters claim that while the EPA stated that the study-reported means from epidemiologic studies that use restricted analyses are more useful for identifying impacts from typical 24-hour exposures than for peak 24-hour exposures, the commenters assert that the studies also indicate that there are health risks at relatively high concentrations below the current level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard that must be addressed.

                    <P>
                        As noted by the commenters, epidemiologic studies that show positive and statistically significant associations between short-term PM
                        <E T="52">2.5</E>
                         exposure and mortality provide support for the causal determination in the 2019 ISA. The EPA also agrees that the available epidemiologic studies include diverse populations that are broadly representative of the U.S. population, including at-risk populations. Further, the EPA agrees that studies evaluated in the 2019 ISA and the ISA Supplement continue to provide evidence of linear, no-threshold concentration-response relationships, but with less certainty in the shape of the curve at lower concentrations (
                        <E T="03">i.e.,</E>
                         below about 8 µg/m
                        <SU>3</SU>
                        ), with some recent studies providing evidence for either a sublinear, linear, or supralinear relationship at these lower concentrations (U.S. EPA, 2019a, section 11.2.4; U.S. EPA, 2022a, section 2.2.3.2).

                    <P>
                        However, findings of positive, significant associations in short-term epidemiologic studies do not directly indicate that short-term effects would occur in areas meeting the 24-hour standard and therefore, do not directly address the question of whether the current 24-hour standard is adequate. While short-term epidemiologic studies evaluate associations between distributions of ambient PM
                        <E T="52">2.5</E>
                         and health outcomes, they do not identify the specific exposures (
                        <E T="03">i.e.,</E>
                         a specific 24-hour concentration) that can lead to the reported effects. Short-term epidemiologic studies evaluate the association between day-to-day variation in daily (24-hour) PM
                        <E T="52">2.5</E>
                         exposure and health endpoints (

                        <E T="52">2.5</E>
                         concentrations over the entire multi-year period of the study, and typically report their results as a relative risk (

                        , the risk of mortality or cardiovascular hospital admissions increases by a certain percentage, across the full range of the 24-hour PM
                        <E T="52">2.5</E>
                         concentrations in the study). This means that there is no specific point in the air quality distribution of any epidemiologic study that represents a “bright line” at and above which effects have been observed and below which effects have not been observed. Nor, as noted above, do these studies allow for any direct inferences about health impacts associated with the short-term “peak” exposures that the primary 24-hour standard is designed to protect against. While there can be considerable variability in daily exposures over a multi-year study period, most of the estimated exposures in these epidemiologic studies reflect days with ambient PM
                        <E T="52">2.5</E>
                         concentrations around the mean or middle of the air quality distributions examined (
                        <E T="03">i.e.,</E>
                         “typical” days rather than days with extremely high or extremely low concentrations). This is true of long-term epidemiologic studies as well. The difference between epidemiologic studies examining associations with long-term exposures and short-term exposures is comparing different levels of exposure over different exposure durations (
                        <E T="03">i.e.,</E>
                         long-term studies exposures are defined as those that are annual or multi-year, while short-term exposures are defined as those that are mostly 24-hour) (U.S. EPA, 2019a, section P.3.1). Thus, in both cases, and in the absence of a discernible threshold, epidemiologic studies of short-term and long-term exposures provide the strongest support and confidence for reported health effect associations around the middle portion of the PM
                        <E T="52">2.5</E>
                         air quality distribution (

                        concentration), which corresponds to the bulk of the underlying data, rather than at the extreme upper or lower ends of the distribution. However, the difference between the annual standard and the 24-hour standard, aside from averaging times, is that the form of the annual standard is a mean PM
                        <E T="52">2.5</E>
                         concentration, which is based on the bulk of the air quality data, while the form of the 24-hour standard is a 98th percentile form, which is based on peak concentrations. Both long-term and short-term epidemiologic studies are informative for determining the appropriate level of the annual PM
                        <E T="52">2.5</E>
                         standard, which is designed to control “typical” daily exposures and risks, because these studies most often report long-term mean (or median) PM
                        <E T="52">2.5</E>
                         concentrations that are representative of “typical” exposures that are associated with health effects. In contrast, while the short-term epidemiologic studies examine health effects associated with shorter exposure durations (
                        <E T="03">e.g.,</E>
                         mostly 24-hour exposures), these studies are less informative for determining the appropriate level of the 24-hour PM
                        <E T="52">2.5</E>
                         standard because these studies do not report the 98th percentile PM
                        <E T="52">2.5</E>
                         concentrations,

                        <FTREF/>
                         which is more directly comparable to the form of the 24-hour standard. Additionally, if the 98th percentile of data were reported, the EPA would consider the peak concentrations observed in these studies (which by definition rarely occur) in conjunction with other supporting evidence. However, as already noted, there is an absence of new information in this reconsideration (either from controlled human exposure studies or epidemiologic studies) suggesting that peak concentrations just below the level of the current 24-hour standard (with its level of 35 µg/m
                        <SU>3</SU>
                        ) are associated with adverse effects. Instead, the evidence links risk to more typical daily exposures near the middle of the air quality distribution—exposures most effectively controlled through a strengthening of the annual standard. As noted in the 2012 final rule, “reducing the annual standard is the most efficient way to reduce the risks from short-term exposures . . . as the bulk of the risk comes from the large number of days across the bulk of the air quality distribution, not the relatively small number of days with peak concentrations” (78 FR 3156, January 15, 2013).

                             In the 2022 PA, the EPA has identified a number of key areas for additional research and data collection for PM

                            , based on the uncertainties and limitations that remain in the scientific evidence and technical information. In addition to research and data collection, the EPA specifically highlights additional information that could be reported in the epidemiologic studies that may help inform future reviews of the primary PM

                             from the 95th to the 99th percentile), as well as the number of days of concentrations and/or health events within each of these percentiles (U.S. EPA, 2022a, section 3.7).

                        As noted above, in evaluating the adequacy of the current standards, the EPA has consistently considered the annual standard (based on arithmetic mean concentrations) and 24-hour standard (based on 98th percentile concentrations) together in evaluating the public health protection provided by the standards against the full distribution of short- and long-term PM
                        <E T="52">2.5</E>
                         exposures. Moreover, the EPA has previously noted that the annual standard is generally controlling in most parts of the country, providing an effective and efficient way to reduce total population risk to both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures, while the 24-hour standard, with its 98th percentile form, provides supplemental protection, particularly for areas with high peak-to-mean ratios of 24-hour PM
                        <E T="52">2.5</E>
                         concentrations (78 FR 3158, January 15, 2013). In such areas, annual average PM
                        <E T="52">2.5</E>
                         concentrations could be quite low, and the 24-hour standard provides a means of ensuring control of episodic peaks possibly associated with strong local or seasonal sources, or PM
                        <E T="52">2.5</E>
                        -related effects that may be associated with shorter-than daily exposure periods. The approach taken in evaluating the adequacy and alternative levels of the annual standard has been to evaluate the long-term mean PM
                        <E T="52">2.5</E>
                         concentrations of both long-term and short-term key epidemiologic studies, where we have the most confidence in the reported health effects association, while also giving some consideration to lower percentiles of the air quality distribution (
                        <E T="03">e.g.,</E>
                         25th percentiles). However, using a similar approach to evaluate the adequacy of the current and any potential alternative levels of the 24-hour standard with short-term epidemiologic studies, as the majority of CASAC and some commenters are suggesting, presents challenges.

                        Short-term epidemiologic studies, including those that use restricted analyses, often report metrics that include mean PM
                        <E T="52">2.5</E>
                         concentrations, with some studies also reporting lower percentiles, such as the 25th percentile. As previously noted above, for studies of daily PM
                        <E T="52">2.5</E>
                         exposure, which examine associations between day-to-day variation in PM
                        <E T="52">2.5</E>
                         concentrations and health outcomes, often over several years, most of the estimated exposures reflect days with ambient PM
                        <E T="52">2.5</E>
                         concentrations around the middle of the air quality distributions examined (
                        <E T="03">i.e.,</E>
                         the mean or median). However, there is not a metric or statistic reported in short-term epidemiologic studies that allows for a direct comparison to the current 24-hour PM
                        <E T="52">2.5</E>
                         standard and its 98th percentile form. While a 98th percentile of PM
                        <E T="52">2.5</E>
                         concentrations is a metric that might be more closely compared to the 24-hour standard level, 98th percentile PM
                        <E T="52">2.5</E>
                         concentrations were not reported in key epidemiologic studies. Consistent with the Administrator's final decision in 2012, the EPA notes that even if 98th percentile values were reported, it would be inappropriate to focus on these concentrations without also considering the impact of a revised annual standard on short-term concentrations, since many areas would be expected to experience decreasing short- and long-term PM
                        <E T="52">2.5</E>
                         concentrations in response to a revised annual standard (78 FR 3156, January 15, 2013). Furthermore, in light of the scarcity of days at the very upper end of the distribution, and to avoid placing undue reliance on the peak concentrations observed in these studies (which by definition rarely occur), the EPA finds that such values would need to be considered in conjunction with other supporting evidence. In addition, as described above, the other lines of evidence available for consideration by the EPA do not indicate that the current primary 24-hour standard requires revision to protect public health with an adequate margin of safety. The EPA notes again the lack of corroborating evidence from controlled human exposure studies. While the EPA agrees with the CASAC that the controlled human exposure studies are limited in their ability to speak to the concentrations at which effects may be elicited in at-risk populations, as discussed above the lowest concentration associated with effects is 37.8 µg/m
                        <SU>3</SU>
                         and the effects observed were “intermediate” outcomes that are not by themselves considered adverse. We also note that, as detailed in section II.A.2.a above, the study that observed intermediate effects at concentrations of 37.8 µg/m
                        <SU>3</SU>
                         was evaluated in the ISA Supplement and the results of this study were inconsistent with the controlled human exposure studies evaluated in the 2019 ISA. Additionally, as noted above, the EPA finds that across all monitors, on average, only 0.41 percent of 4-hour observations reach PM
                        <E T="52">2.5</E>
                         concentrations higher than 38 µg/m
                        <SU>3</SU>
                         in areas meeting the current 24-hour 
                        <PRTPAGE P="16272"/>
                        standard and a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                        . Given the rarity of these occurrences and the fact that the effects associated with exposures to this PM
                        <E T="52">2.5</E>
                         concentration have not been found to be adverse in and of themselves, the EPA finds it reasonable to conclude that this pattern of air quality will protect at-risk populations, even though such populations were not in the study groups. The EPA concludes that further evidence would be needed at specific short-term (
                        <E T="03">i.e.,</E>
                         hourly or daily) concentrations below the level of the current 24-hour standard to support any revision to the current 24-hour standard.

                    <P>
                        With regard to the data that are available from the short-term epidemiologic studies (which, as noted, do not include 98th percentile values), the EPA considers it inappropriate to utilize the study-reported means from the short-term epidemiologic evidence to assess the adequacy of the 24-hour standard, with its 98th percentile form, considering that the study-reported mean concentrations do not provide meaningful insight regarding the frequency or health significance of peak concentrations occurring during the study period. As indicated in the 2022 PA, the study-reported means of short-term epidemiologic studies do not serve a purpose in determining a level at which we can confidently attribute effects to the impact of “peak” exposures. The 24-hour standard is intended to provide supplemental protection against short-term peak exposures and while there is a general relationship between mean concentrations and 98th percentile concentrations in individual locations, such relationships vary by location and there is not an established relationship that can be relied upon to predict 98th percentile concentrations based on mean PM
                        <E T="52">2.5</E>
                         concentrations reported in multi-city epidemiologic studies. Instead, mean concentrations from short-term epidemiologic studies are more useful in addressing questions regarding the effects of “typical” or average 24-hour exposures, which are addressed through the annual standard. For this reason, the EPA does consider the mean concentrations of short-term studies (as well as the means from the long-term studies) in evaluating the level of the annual standard, which the EPA recognizes as the generally controlling standard for both long- and short-term exposures. However, the EPA does not agree with commenters that it is appropriate to use means from short-term epidemiologic studies as the basis for a decision-making framework to determine the adequacy of the current 24-hour standard, with its 98th percentile form.

                        As described in the proposal (88 FR 5613, January 27, 2023), the 2022 PA also noted the epidemiologic studies that restrict 24-hour average PM
                        <E T="52">2.5</E>

                         concentration for the restricted analysis, the mean of the restricted analysis is presumably less than the mean PM

                         concentration in the main analysis. Restricted analyses from long-term and short-term exposure epidemiologic studies are informative in providing support that the health effects associations are not driven by just the upper peaks of the PM

                        In their review of the 2021 draft PA, the majority of the CASAC highlighted three U.S.-based epidemiologic studies that restricted 24-hour average PM

                        <SU>3</SU>
                        , the 24-hour standard level should be set at the concentration at which the analysis was restricted (
                        <E T="03">e.g.,</E>
                         25 µg/m
                        <SU>3</SU>
                        ). However, the EPA notes that neither the CASAC nor public commenters provided any detail regarding, how, in their view, these studies demonstrate that the level of the current 24-hour standard is not adequate, and/or how these studies demonstrate what revised level of the 24-hour standard would provide requisite public health protection with an adequate margin of safety. The EPA considers that such an approach would have several important limitations. First, the approach assumes that a specific point on the air quality distribution (
                        <E T="03">e.g.,</E>
                         the point at which the analysis was restricted) is where health effects are exhibited and where we have the most confidence in the reported association. However, in addition to the limitations associated with the short-term epidemiologic studies outlined above, the EPA does not agree that it would be appropriate to identify the requisite level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard based on the specific concentration at which the analyses restrict their studies. The choice to restrict the data at a particular concentration is in effect arbitrary, and does not establish that any particular effects are attributable to that concentration as opposed to other concentrations within the restricted analysis.
                    </P>
                    <P>
                        Further, these restricted analyses do not report the PM
                        <E T="52">2.5</E>
                         concentration at the 98th percentile of data or other metrics relating to the upper end of the distribution that could provide information about health risks associated with peak exposures. For example, the CASAC does not provide a discussion of what the comparable 98th percentile concentration is in the distribution of remaining 24-hour PM
                        <E T="52">2.5</E>
                         concentrations of restricted analyses (because such data is not reported by the study authors) and what degree of confidence the Administrator should place on those upper percentile values (
                        <E T="03">e.g.,</E>
                         98th percentile values). In order to identify a level of the 24-hour standard based on associations between the “upper end” of exposures, either in the unrestricted or the restricted analyses, and adverse health effects, it would be necessary to have both greater detail on the distribution of air quality in the study and greater confidence in the reported association at the peak concentrations such as the 98th percentile—in other words, a better understanding of how specific 24-hour concentrations correspond to the frequency and total number of observed health events in the study.
                    </P>
                    <P>
                        Further, the EPA notes that when resulting analyses based on the 
                        <PRTPAGE P="16273"/>
                        restricted dataset continue to find positive associations between the remaining air quality distribution and health effects, it suggests that the relationship was in fact not driven primarily by the upper tail (now removed from the dataset) but rather by lower portions of the distribution of air quality. In other words, we have no confidence that the remaining upper end of the air quality distribution is driving the remaining associations reported in the restricted analyses, as opposed to the vast array of health events at and around the mean PM
                        <E T="52">2.5</E>
                         concentration. In fact, it is reasonable to conclude that to effectively address the health effects observed in the study, it is necessary to control not just the peak concentrations but to reduce the bulk of the exposures (occurring near the mean), a task more effectively achieved, as noted above through a tightening of the annual standard, which has the effect of shifting the entire distribution of PM
                        <E T="52">2.5</E>
                         concentrations downward (both peaks and means). Therefore, while the EPA agrees that both short- and long-term epidemiologic studies that completed restricted analyses and reported the resulting study means could be used to inform conclusions regarding the adequacy of the annual standard, given that the resulting study means (when reported) could be evaluated in the context of the decision framework described above for informing decisions on the level of the annual standard, the EPA considers that current short-term epidemiologic studies that restrict analyses are subject to the same limitations outlined above for current short-term epidemiologic studies in how they can be used in a decision-making framework to inform the adequacy and alternative level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. As such, while the available short-term epidemiologic studies that restrict their analyses are useful for informing conclusions regarding the strength of the associations for health outcomes, they are not, as currently designed, as useful for informing conclusions regarding the adequacy of the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In reaching this conclusion, the EPA notes that the majority of the CASAC did not address the limitations of these studies outlined in the 2021 draft PA, particularly in the context of the 24-hour standard with its 98th percentile form. Among the future research needs identified by the EPA in the 2022 final PA, the Agency noted a number of gaps in the currently available information reported in the epidemiologic studies of short-term exposure, including “descriptive statistics of PM
                        <E T="52">2.5</E>
                         concentrations at individual percentiles from the 95th percentile to the 99th percentile, as well as the number of days of concentrations and/or health events within each of these percentiles” and other descriptive statistics and details regarding analytical design in studies employing restricted analyses (U.S. EPA, 2022b, pp. 3-225 to 3-226). Such information could significantly improve the EPA's ability to draw conclusions from these studies with regard to the adequacy of the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard.
                    </P>
                    <P>
                        Due to the limitations and uncertainties outlined above, in reaching his decision on the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator judges that the information from currently available short-term epidemiologic studies, including those that use restricted analyses, is inadequate to inform decisions regarding the adequacy of the current 24-hour standard. Additionally, consistent with the final decision in 2012, the EPA continues to view an approach that focuses on setting a generally controlling annual standard as the most effective and efficient way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures. Potential air quality changes associated with meeting an annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         will result in lowering risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposure by lowering the overall air quality distribution. As discussed above, reducing the annual standard is the most efficient way to reduce the risks from short-term exposures identified in the epidemiologic studies, as the available evidence suggests the bulk of the risk comes from the large number of days across the bulk of the air quality distribution, not the relatively small number of days with peak concentrations. However, as in the 2012 review, the Administrator recognizes that an annual standard alone would not be expected to offer sufficient protection with an adequate margin of safety against the effects of short-term PM
                        <E T="52">2.5</E>
                         exposures in all parts of the country, particularly in areas with high peak-to-mean ratios, and concludes that it is appropriate to continue to provide supplemental protection by means of a 24-hour standard. In so doing, the Administrator concludes that retaining the level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard of 35 µg/m
                        <SU>3</SU>
                         will provide requisite protection against short-term peak PM
                        <E T="52">2.5</E>
                         concentrations, in conjunction with a revised annual standard level of 9.0 µg/m

                    <HD SOURCE="HD3">4. Administrator's Conclusions</HD>
                    <P>
                        This section summarizes the Administrator's considerations and conclusions related to the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards and presents his decision to revise the primary annual PM
                        <E T="52">2.5</E>
                         standard to a level of 9.0 µg/m
                        <SU>3</SU>
                         and retain the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In establishing primary standards under the Act that are “requisite” to protect public health with an adequate margin of safety, the Administrator is seeking to establish standards that are neither more nor less stringent than necessary for this purpose. He recognizes that the requirement to provide an adequate margin of safety was intended to address uncertainties associated with inconclusive scientific and technical information and to provide a reasonable degree of protection against hazards that research has not yet identified. However, the Act does not require that primary standards be set at a zero-risk level; rather, the NAAQS must be sufficiently protective, but not more stringent than necessary.
                    </P>
                    <P>
                        Given these requirements, the Administrator's final decision in this reconsideration is a public health policy judgment drawing upon scientific and technical information examining the health effects of PM
                        <E T="52">2.5</E>
                         exposures, including how to consider the range and magnitude of uncertainties inherent in that information. This public health policy judgment is based on an interpretation of the scientific and technical information that neither overstates nor understates its strengths and limitations, nor the appropriate inferences to be drawn, and is informed by the Administrator's consideration of advice from the CASAC and public comments received on the proposal.

                    <P>
                        The initial issue to be addressed in the reconsideration of the primary PM
                        <E T="52">2.5</E>
                         standards is whether, in view of the advances in scientific knowledge and other information reflected in the 2019 ISA, ISA Supplement, and 2022 PA, the current standards are requisite to protect public health with an adequate margin of safety. In considering the adequacy of the current suite of primary PM
                        <E T="52">2.5</E>
                         standards, the Administrator has considered the large body of evidence presented and assessed in the 2019 ISA and ISA Supplement, the conclusions presented in the 2022 PA, the views expressed by the CASAC, and public comments. The Administrator has taken into account both evidence- and risk-based considerations in developing final conclusions on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards. The Administrator has additionally 
                        <PRTPAGE P="16274"/>
                        considered the associated public health policy judgments and judgments about the uncertainties inherent in the scientific evidence and quantitative analyses that are integral to the conclusions on the adequacy of the current primary PM
                        <E T="52">2.5</E>
                         standards.
                    </P>
                    <P>
                        In evaluating the adequacy of the current standards, the Administrator first recognizes the longstanding body of health evidence supporting relationships between PM
                        <E T="52">2.5</E>
                         exposures (short- and long-term) and mortality and serious morbidity effects. The evidence available in this reconsideration (
                        <E T="03">i.e.,</E>
                         that assessed in the 2019 ISA and ISA Supplement) and summarized above in section II.A.2.a reaffirms, and in some cases strengthens, the conclusions from the 2009 ISA regarding the health effects of PM
                        <E T="52">2.5</E>
                         exposures. Recent epidemiologic studies demonstrate generally positive and often statistically significant associations between PM
                        <E T="52">2.5</E>
                         exposures and a number of health effects, including non-accidental, cardiovascular, or respiratory mortality; cardiovascular or respiratory hospitalizations or emergency room visits; and other mortality/morbidity outcomes (
                        <E T="03">e.g.,</E>
                         lung cancer mortality or incidence, asthma development). Recent controlled human exposure and animal toxicological studies, as well as evidence from epidemiologic panel studies, strengthens support for potential biological pathways through which PM
                        <E T="52">2.5</E>
                         exposures could lead to the serious effects reported in many population-level epidemiologic studies, including support for pathways that could lead to cardiovascular, respiratory, nervous system, and cancer-related effects. In considering the available scientific evidence, and consistent with approaches employed in past NAAQS reviews, the Administrator places the most weight on evidence supporting “causal” or “likely to be causal” relationship with long or short-term PM
                        <E T="52">2.5</E>
                         exposures. In addition, the Administrator also takes note of those populations identified to be at greater risk of PM
                        <E T="52">2.5</E>
                        -related health effects, as characterized in the 2019 ISA and ISA Supplement, and the potential public health implications.
                    </P>
                    <P>
                        In evaluating what existing or revised standards may be requisite to protect public health, as described above in section II.A.2, the Administrator's approach recognizes that the current annual standard (based on arithmetic mean concentrations) and 24-hour standard (based on 98th percentile concentrations), together, are intended to provide public health protection against the full distribution of short- and long-term PM
                        <E T="52">2.5</E>
                         exposures. This approach recognizes that changes in PM
                        <E T="52">2.5</E>
                         air quality designed to meet either the annual or the 24-hour standard would likely result in changes to both long-term average and short-term peak PM
                        <E T="52">2.5</E>
                         concentrations.
                    </P>
                    <P>
                        Further, consistent with the approach adopted in 2012, the Administrator concludes that the most effective and efficient way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures is to set a generally controlling annual standard, and to provide supplemental protection against the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations by means of a 24-hour standard set at the appropriate level. In reaching this conclusion, the Administrator explicitly recognizes that air quality changes associated with meeting a revised annual standard would result in lowering risks associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures by lowering the overall distribution of air quality concentrations, leading to not only in lower short- and long-term PM
                        <E T="52">2.5</E>
                         concentrations near the middle of the air quality distribution, but also in fewer and lower short-term peak PM
                        <E T="52">2.5</E>
                         concentrations. Similarly, the Administrator recognizes that changes in air quality to meet a 24-hour standard, would result not only in fewer and lower peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations, but also in lower annual average PM
                        <E T="52">2.5</E>
                         concentrations. However, as noted in 2012, he also recognizes that an approach that relies on setting the level of the 24-hour standard such that the 24-hour standard is generally controlling would be less effective and result in less uniform protection across the U.S. than an approach that focuses on setting a generally controlling annual standard. Thus, he concludes that relying on a revised annual standard as the controlling standard will reduce aggregate risks associated with both long- and short-term exposures more consistently than a generally controlling 24-hour standard. He further concludes that retaining a 24-hour standard at the appropriate level will ensure an adequate margin of safety against short-term effects in areas with high peak-to-mean ratios.

                    <P>
                        In light of his focus on the annual standard as the generally controlling standard, in considering whether the primary PM
                        <E T="52">2.5</E>
                         standards are adequate, the Administrator first considers information available to inform his final conclusions regarding the primary annual PM
                        <E T="52">2.5</E>
                         standard. In so doing, he notes that in this reconsideration, a large number of key U.S. epidemiologic studies report positive and statistically significant associations for air quality distributions with overall mean PM
                        <E T="52">2.5</E>
                         concentrations that are well below the current level of the annual standard of 12.0 μg/m
                        <SU>3</SU>
                        . He further recognizes that there is additional scientific evidence assessed in the 2019 ISA and newly assessed in this reconsideration in the ISA Supplement that can provide supplemental information to inform his decisions. In addition to the key U.S. epidemiologic studies, the Administrator also recognizes that key Canadian epidemiologic studies also demonstrate positive and statistically significant associations at concentrations below 12 μg/m
                        <SU>3</SU>
                        . He also recognizes that epidemiologic studies that restrict annual average PM
                        <E T="52">2.5</E>
                         concentrations to below 12 μg/m
                        <SU>3</SU>
                         also provide support for positive and statistically significant associations at lower mean PM
                        <E T="52">2.5</E>
                         concentrations, as do accountability studies that also suggest public health improvements may occur at concentrations below 12 μg/m
                        <SU>3</SU>
                        .
                    </P>
                    <P>
                        With regard to the available scientific evidence to inform his final decisions on the adequacy of the current 24-hour standard, the Administrator finds that there is less information available to support decisions on the 24-hour standard than that summarized above for the annual standard. The Administrator first notes that controlled human exposure studies, including those newly available in this reconsideration, demonstrate effects following short-term PM
                        <E T="52">2.5</E>
                         exposures at concentrations higher than the current 24-hour standard. The Administrator also considers air quality analyses conducted in the 2022 PA and in responding to public comments, as described above in section II.B.3, that evaluate PM
                        <E T="52">2.5</E>
                         concentrations in ambient air for similar durations to the controlled human exposure studies. As noted above, these air quality analyses indicate that the current 24-hour standard, particularly in conjunction with the revised level of the annual standard, provides a high degree of protection against subdaily PM
                        <E T="52">2.5</E>
                         concentrations that have been shown to elicit effects in controlled human exposure studies. The Administrator considers a limited number of available epidemiologic studies that report associations with health effects when the analyses are restricted to daily PM
                        <E T="52">2.5</E>
                         concentrations below 35 μg/m
                        <SU>3</SU>
                        . As described above, although these studies are useful in demonstrating that health effects are associated with exposure to daily PM
                        <E T="52">2.5</E>
                         concentrations in the lower part of the air quality distribution, they do not provide information about health effects associated with the short-term 
                        <PRTPAGE P="16275"/>
                        “peak” exposures that the 24-hour standard is designed to protect against. Accordingly, these studies have limited relevance in informing a decision about the appropriate level of the 24-hour standard.

                    <P>
                        In addition to the scientific evidence, the Administrator also considers the information from the risk assessment. In so doing, he notes that the risk assessment estimates that the current primary annual PM
                        <E T="52">2.5</E>
                         standard could allow a substantial number of deaths in the U.S. With respect to the 24-hour standard, the Administrator recognizes that there are only a small number of study areas where the 24-hour standard is controlling and changes in the 24-hour standard level are estimated to have a much smaller impact on public health. The Administrator recognizes that while the risk estimates can help to place the evidence for specific health effects into a broader public health context, they should be considered along with the inherent uncertainties and limitations of such analyses when informing judgments about the potential for additional public health protection associated with PM
                        <E T="52">2.5</E>
                         exposure and related health effects. While the Administrator recognizes that these uncertainties are important, he also notes that the general magnitude of the risk estimates provide support for significant public health impacts, particularly for lower alternative annual standard levels.

                    <P>
                        In reaching his final conclusions regarding the adequacy of the primary PM
                        <E T="52">2.5</E>
                         standards, the Administrator also considers the CASAC's advice and recommendations, as well as public comments. With respect to the CASAC's advice, the Administrator recognizes that, in their review of the 2021 draft PA, the CASAC reached consensus that the current primary annual PM
                        <E T="52">2.5</E>
                         standard is not adequate and that it is not sufficiently protective of public health. The Administrator also takes note of the CASAC's advice in their review of the 2019 draft PA, where the CASAC did not reach consensus on the adequacy of the primary annual PM
                        <E T="52">2.5</E>
                         standard, with the minority recommending revision and the majority recommending the standard be retained. Furthermore, he recognizes that in reviewing the 2019 draft PA, the CASAC reached consensus regarding the adequacy of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, concluding that the standard should be retained. Conversely, in their review of the 2021 draft PA, the majority of the CASAC advised that the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard is not adequate and recommended revising the level of the standard, while the minority of the CASAC concluded that the standard was adequate and should be retained. However, in considering the advice of the CASAC collectively in the context of this reconsideration, the Administrator recognizes that the 2021 draft PA included scientific evidence and quantitative risk information that was not available in the 2019 draft PA, and therefore, the advice and recommendations of the CASAC in their review of the 2021 draft PA are based on consideration of the full body of scientific evidence available in this reconsideration, including the evidence evaluated in the 2019 ISA and the ISA Supplement.
                    </P>
                    <P>
                        The Administrator recognizes that much of the scientific evidence available in this reconsideration was also available in the 2019 ISA and was considered by the then-Administrator when he decided that the current primary PM
                        <E T="52">2.5</E>
                         standards are requisite to protect public health with an adequate margin of safety. However, as described in section I.C.5.b above, in reaching his decision to reconsider the 2020 final decision, the Administrator also recognized that there were a number of studies published since the literature cutoff date of the 2019 ISA that were raised by some members of the CASAC in their review of the 2019 draft PA, in public comments on the 2020 proposal, and in the petitions for reconsideration. As such, the expansion of the air quality criteria in this reconsideration to encompass both the 2019 ISA and the additional scientific evidence evaluated in the ISA Supplement, along with evidence and updated quantitative analyses in the 2022 PA also provided an expanded record for the CASAC's review and public comments as a part of this reconsideration. Taken together, the 2019 ISA, ISA Supplement, and 2022 PA, along with the CASAC's advice and recommendations and public comments, provide the Administrator with additional information for consideration in reaching his final conclusions in this reconsideration. As a result, the record before him notably expands upon and strengthens the basis for the conclusions of the 2019 ISA while reducing some uncertainties that were identified in the 2020 final action.
                    </P>
                    <P>
                        In considering the available information in this reconsideration, the current Administrator reached different conclusions regarding the appropriate weight to place on certain aspects of the evidence than the then-Administrator in the 2020 final decision. For example, in reaching his conclusions on the primary annual PM
                        <E T="52">2.5</E>
                         standard in 2020, the then-Administrator concluded that it was appropriate to place more weight on epidemiologic studies that used ground-based monitors and to place less weight on the studies that used hybrid model-based approaches, citing to increased uncertainties associated with this new and emerging approach to estimating exposure. In placing more weight on the key U.S. monitor-based studies, the then-Administrator noted that the majority of these studies had mean concentrations at or above the level of the annual standard (12.0 µg/m
                        <SU>3</SU>
                        ). However, unlike the approach for considering such studies in the 2012 review, the then-Administrator concluded that it was appropriate to consider the study-reported means collectively, and in so doing, he placed weight on the average of the study-reported means (or medians) across the U.S. monitor-based studies of 13.5 µg/m
                        <SU>3</SU>
                        , and noted that this concentration was above the level of the standard (85 FR 82717, December 18, 2020). In contrast, in this reconsideration, the current Administrator judges that it is appropriate to consider the individual study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations from not only the U.S. monitor-based epidemiologic studies, but also the U.S. hybrid model-based epidemiologic studies, which are an advancement in the available science since the completion of the 2009 ISA. The current Administrator also adopts an approach similar to some previous approaches for the PM NAAQS in which he judges it most appropriate to set the level of the standard to somewhat below the lowest long-term study-reported mean PM
                        <E T="52">2.5</E>
                         concentration reported in key U.S. epidemiologic studies, which is 9.3 µg/m
                        <SU>3</SU>
                        . The study that reports the long-term mean PM
                        <E T="52">2.5</E>
                         concentration of 9.3 µg/m
                        <SU>3</SU>
                         is newly available in this reconsideration and is evaluated in the ISA Supplement. In the 2019 ISA, the lowest long-term study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations for U.S.-based studies that use ground-based monitors and hybrid model-based approaches are 9.9 µg/m
                        <SU>3</SU>
                         and 10.7 µg/m
                        <SU>3</SU>
                        , respectively. In judging that it is appropriate to consider both monitor- and hybrid model-based epidemiologic studies and that it is appropriate to adopt an approach to set the level of the standard to somewhat below the lowest long-term mean PM
                        <E T="52">2.5</E>
                         concentration, the current Administrator judges that the available scientific evidence—evaluated in both the 2019 ISA and in the ISA Supplement—provide support for his conclusion that that current primary 
                        <PRTPAGE P="16276"/>
                        PM
                        <E T="52">2.5</E>
                         standard is not adequate and should be revised.
                    </P>
                    <P>
                        In addition to adopting a different approach than the previous Administrator for considering the long-term mean PM
                        <E T="52">2.5</E>
                         concentrations from key U.S. epidemiologic studies (one more consistent with the approach of the EPA in other prior reviews), the current Administrator both has information newly available in this reconsideration before him and is reaching different conclusions about how to weigh the evidence before him in reaching his final conclusions. For example, in reaching his final decision in 2020, the then-Administrator was concerned about placing too much weight on epidemiologic studies to inform his conclusions on the adequacy of the primary PM
                        <E T="52">2.5</E>
                         standards, noting that the epidemiologic studies do not identify particular PM
                        <E T="52">2.5</E>
                         concentrations that cause effects and cannot alone identify a specific level at which to set the standard. In so doing, the then-Administrator placed greater weight on the uncertainties and limitations associated with the epidemiologic studies, including exposure measurement error, potential confounding by copollutants, increased uncertainty of associations at lower PM
                        <E T="52">2.5</E>
                         concentrations, and heterogeneity of effects across different cities or regions (85 FR 82716, December 18, 2020). The Administrator recognizes that in reaching these judgments, the then-Administrator took into consideration the views of some members of the CASAC, who, in their advice on the 2019 draft PA, expressed the view that the current PM NAAQS should be retained because reported associations between short- and long-term PM
                        <E T="52">2.5</E>
                         exposures and adverse health outcomes “can reasonably be explained in light of uncontrolled confounding and other potential sources of error and bias” (Cox, 2019b, p. 8 of consensus responses).
                    </P>
                    <P>
                        In this reconsideration, the current Administrator notes that the ISA Supplement evaluates additional studies that employed statistical approaches that attempted to more extensively account for confounders and are more robust to model misspecification (
                        <E T="03">i.e.,</E>
                         used alternative methods for confounder control, which are sometimes referred to as causal modeling or causal inference methods) that build upon those studies available and evaluated in the 2019 ISA (U.S. EPA, 2019, sections 11.1.2.1 and 11.2.2.4). These studies report consistent positive associations between long-term and short-term PM
                        <E T="52">2.5</E>
                         exposure and total mortality and cardiovascular effects (U.S. EPA, 2022a, section 3.2.2.3). In considering the epidemiologic evidence evaluated in the 2019 ISA, along with the newly available studies evaluated in the ISA Supplement, the current Administrator also recognizes that there are uncertainties and limitations associated with the epidemiologic studies, but judges that it is appropriate to place less weight on these uncertainties than the then-Administrator placed on them in reaching his final decision in 2020, given the strength of the longstanding large body of epidemiologic evidence, employing a variety of study designs, that demonstrates associations between long- and short-term PM
                        <E T="52">2.5</E>
                         exposures and health effects across multiple U.S. cities and in diverse populations, including in studies examining populations and lifestages that may be at comparatively higher risk of experiencing a PM
                        <E T="52">2.5</E>
                        -related health effect (
                        <E T="03">e.g.,</E>
                         older adults, children).
                    </P>
                    <P>In reaching this final decision, the Administrator recognizes he is differing not only with the prior Administrator but also with the advice some members of the CASAC provided during their review of the 2019 draft PA. Specifically, taking into consideration the strength of the evidence providing support for causality determinations, the advice of other members of the CASAC and the need to protect public health with an adequate margin of safety, the current Administrator disagrees with these members of CASAC regarding the weight to be given to epidemiologic evidence “based on its methodological limitations” (Cox, 2019b, p. 8 of consensus responses), such as the possibility “that such associations could reasonably be explained by uncontrolled confounding and other potential sources of error and bias” (Cox, 2019b, p. 8 of consensus responses).</P>
                    <P>
                        As another example of information that was not available to the CASAC in providing advice to the Administrator in reaching his final decision in 2020, the then-Administrator noted in his final decision that, while some members of the CASAC and public commenters highlighted a number of accountability studies that examined past reductions in ambient PM
                        <E T="52">2.5</E>
                         concentrations and the degree to which those reductions have resulted in public health improvements, the small number of available accountability studies did not examine air quality with starting concentrations meeting the primary annual PM
                        <E T="52">2.5</E>
                         standard of 12.0 µg/m
                        <SU>3</SU>
                        <E T="52">.</E>
                         The then-Administrator took into consideration the absence of such accountability studies, as part of his consideration of the full body of scientific evidence, in reaching his judgment that there was considerable uncertainty in the potential for increased public health protection from further reductions in ambient PM
                        <E T="52">2.5</E>
                         concentrations beyond those achieved under the existing primary PM
                        <E T="52">2.5</E>
                         NAAQS (85 FR 82717, December 18, 2020). However, there are several accountability studies available since the literature cutoff date of the 2019 ISA and evaluated in the ISA Supplement in this reconsideration that have starting concentrations (or concentrations prior to the policy or intervention) below 12.0 µg/m
                        <SU>3</SU>
                         (Corrigan et al, 2018; Henneman et al., 2019; Sanders et al., 2020a). The current Administrator concludes that, while the number of available accountability studies is limited, he recognizes that these studies provide supplemental information for consideration for informing decisions on the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard along with the full body of evidence.

                    <P>
                        As EPA has frequently noted throughout this document, the extent to which the current primary PM
                        <E T="52">2.5</E>
                         standards are judged to be adequate depends in part on science policy and public health policy judgments to be made by the Administrator on the strength and uncertainties of the scientific evidence, such as how to consider epidemiologic evidence and the need for an adequate margin of safety in setting the standards. Thus, it would be pure speculation to guess whether the then-Administrator would have reached the same or different conclusions in the 2020 final decision had the record before him included the newly available information in this reconsideration.

                         However, the current Administrator concludes that, for the reasons explained herein that, in his judgment, based on the record before him in this reconsideration, it is necessary and appropriate to revise the primary annual PM
                        <E T="52">2.5</E>

                             standard to within the range of 10-11 µg/m

                         standard is not adequate to protect public health with an adequate margin of safety. In addition, he finds the available information insufficient to call into question the adequacy of the public health protection afforded by the current primary 24-hour PM
                        <E T="52">2.5</E>

                         standards in order to achieve the requisite protection for public health, with an adequate margin of safety, against long- and short-term PM

                         exposures the Administrator considers the four basic elements of the NAAQS (indicator, averaging time, form, and level) collectively. With respect to indicator, the Administrator recognizes that the scientific evidence in this reconsideration, as in previous reviews, continues to provide strong support for health effects associated with PM
                        <E T="52">2.5</E>
                         mass. He notes the 2022 PA conclusion that the available information continues to support the PM
                        <E T="52">2.5</E>
                         mass-based indicator and remains too limited to support a distinct standard for any specific PM

                         component or group of components, and too limited to support a distinct standard for the ultrafine fraction of PM (U.S. EPA, 2022b, section 3.6.3.2.1). In its advice on the adequacy of the current primary PM

                         standards in their review of the 2021 draft PA, the CASAC reached consensus that the PM

                         Additionally, there was no information in the public comments that provided a rationale for an alternative indicator. For all of these reasons, the Administrator concludes that it is appropriate to retain PM

                        Consistent with his proposed conclusions regarding averaging time, the Administrator notes that the scientific evidence continues to provide strong support for health effect associations with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures (88 FR 5618, January 27, 2023). Epidemiologic studies continue to provide strong support for health effects associated with short-term PM
                        <E T="52">2.5</E>
                         exposures based on 24-hour averaging periods, and associations in epidemiologic studies with subdaily estimates are less consistent and, in some cases, smaller in magnitude (88 FR 5618, January 27, 2023). Taken together, the 2019 ISA concludes that epidemiologic studies do not indicate that subdaily averaging periods are more closely associated with health effects than the 24-hour average exposure metric (U.S. EPA, 2019a, section 1.5.2.1). In addition, controlled human exposure and panel-based studies of subdaily exposures typically examine subclinical effects rather than the more serious population-level effects that have been reported to be associated with 24-hour exposures (
                        <E T="03">e.g.,</E>
                         mortality, hospitalizations). While recent controlled human exposure studies provide consistent evidence for cardiovascular effects following PM
                        <E T="52">2.5</E>
                         exposures for less than 24 hours (
                        <E T="03">i.e.,</E>
                         &lt;30 minutes to 5 hours), air quality analyses have shown that the current averaging times can effectively protect against the exposure concentrations in these studies. This information does not indicate that a revision to the averaging time is necessary to provide additional protection against subdaily PM
                        <E T="52">2.5</E>
                         exposures, beyond that provided by the current primary annual and 24-hour PM

                        <E T="52">2.5</E>
                         standards should be retained, without revision (Sheppard, 2022a, p. 2 of consensus letter).

                         The Administrator also considers the relatively few public comments received that support a subdaily averaging time, but concludes that the currently available information does not provide support for an alternate averaging time. Consistent with his proposed decision, the Administrator concludes that it is appropriate to retain the annual and 24-hour averaging times for the primary PM

                        With regard to form, the Administrator first notes that the EPA has set both an annual standard and a 24-hour standard to provide protection from health effects associated with both long- and short-term exposures to PM
                        <E T="52">2.5</E>

With regard to the form of the annual standard, the Administrator recognizes that a large majority of the recently available epidemiologic studies continue to report associations between health effects and annual average PM
                        <E T="52">2.5</E>
                         concentrations. These studies of annual average PM

                         exposures. In its review of the 2021 draft PA, the CASAC reached consensus that the form of the annual standard (

                        With regard to the form of the 24-hour standard (98th percentile, averaged over three years), epidemiologic studies continue to provide strong support for health effect associations with short-term (
                        <E T="03">e.g.,</E>
                         mostly 24-hour) PM
                        <E T="52">2.5</E>
                         exposures, and controlled human exposure studies provide evidence for health effects following single short-term “peak” PM
                        <E T="52">2.5</E>
                         exposures (88 FR 5618, January 27, 2023). Therefore, the Administrator concludes that the evidence supports retaining a standard focused on providing supplemental protection against short-term peak exposures and supports a 98th percentile form for a 24-hour standard, in combination with a primary annual PM
                        <E T="52">2.5</E>
                         standard with its annual mean averaged over three years form. As described in the proposal and in responding to comments in section II.B.3 above, the Administrator further notes that the 98th percentile, averaged over three years, form also provides an appropriate balance between limiting the occurrence of peak 24-hour PM
                        <E T="52">2.5</E>
                         concentrations and identifying a stable target for risk management programs (U.S. EPA, 2022b, section 3.6.3.2.3). Furthermore, the Administrator notes that the multi-year percentile form (
                        <E T="03">i.e.,</E>
                         averaged over three years) offers greater stability to the air quality management process by reducing the possibility that statistically unusual indicator values will lead to transient violations of the standard. This conclusion is also supported by the CASAC's advice in their review of the 2021 draft PA, where they reached consensus that the form for the primary PM
                        <E T="52">2.5</E>
                         standards should be retained, without revision (Sheppard, 2022a, p. 2 of consensus letter).

                        The Administrator also recognizes that the CASAC recommended that in future reviews, the EPA also consider alternative forms for the primary 24-hour PM
                        <E T="52">2.5</E>

                        p. 18 of consensus responses). Based on the CASAC's advice, the proposal solicited comment on alternatives to the current form for consideration in future reviews (88 FR 5619, January 27, 2023). The Administrator recognizes that there were a limited number of public comments related to the form of the primary PM

                         standards as discussed in section II.D.3 above and in the Response to Comments document, and notes that, the EPA will consider the information provided by the commenters regarding the form of the 24-hour PM

                         standard in the next review of the PM NAAQS. Consistent with his proposed decision, in considering the information summarized above, the Administrator concludes that it is appropriate to retain the forms of the current annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards.

                         standards to provide the requisite public health protection with an adequate margin of safety, the Administrator next evaluates the appropriate levels of the primary PM
                        <E T="52">2.5</E>
                         standards, beginning with the annual PM
                        <E T="52">2.5</E>
                         standard. In having carefully considered public comments related to the primary annual PM
                        <E T="52">2.5</E>
                         standard, the Administrator believes that the fundamental conclusions regarding the scientific evidence and quantitative information that supported his proposed conclusions (as described in the 2019 ISA, ISA Supplement, 2022 PA, and the proposal) remain valid. In considering the level at which the primary annual PM
                        <E T="52">2.5</E>
                         standard should be set, the Administrator considers the entire body of evidence and information, giving appropriate weight to each part of that body of evidence and information. He continues to place the greatest weight in this reconsideration on the available scientific evidence that provides support for associations between health effects and long- and short-term PM
                        <E T="52">2.5</E>
                         exposures. In conjunction with his decisions to retain the current indicator, averaging time, and form as described above, the Administrator is revising the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard to 9.0 µg/m
                        <SU>3</SU>
                        . In so doing, he is selecting a primary annual PM
                        <E T="52">2.5</E>
                         standard that, together with the primary 24-hour PM

                         standard, provides requisite public health protection with an adequate margin of safety, based on his judgments about and interpretation of the scientific evidence and quantitative risk information.

                         builds upon his conclusion that the overall body of scientific evidence and quantitative risk information calls into question the adequacy of public health protection afforded by the current standard, particularly for at-risk populations. Consistent with his consideration of the available information in reaching his proposed decisions, the Administrator's final decision on the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard places the greatest emphasis on key U.S. epidemiologic studies that report associations between long- and short-term PM
                        <E T="52">2.5</E>
                         exposures and mortality and morbidity. As in the proposal, and as discussed further below, he views additional epidemiologic studies (
                        <E T="03">i.e.,</E>
                         studies that employ alternative methods for confounding control, studies that employ restricted analyses, and accountability studies), the controlled human exposure studies, and the risk assessment as providing supplemental information in support of his decision to revise the current annual standard, but recognizes that some of these lines of evidence and information provide a more limited basis for selecting a particular standard level among a range of options. See 
                        <E T="03">Mississippi,</E>
                         744 F. 3d at 1351-52 (studies can legitimately support a decision to revise the standard, but not provide sufficient information to justify their use in setting the level of a revised standard).

                    <P>
                        Given his consideration of the scientific evidence, quantitative risk information, advice from the CASAC, and public comments, the Administrator judges that a primary annual PM
                        <E T="52">2.5</E>
                         standard with a level of 9.0 µg/m
                        <SU>3</SU>
                         is requisite to protect public health with an adequate margin of safety. He notes that the determination of what constitutes an adequate margin of safety is expressly left to the judgment of the EPA Administrator. See

                         744 F.3d at 1353. He further notes that in evaluating how particular standards address the requirement to provide an adequate margin of safety, it is appropriate to consider such factors as the nature and severity of the health effects, the size of the at-risk populations, and the kind and degree of the uncertainties present. In considering the need for an adequate margin of safety, the Administrator notes that a primary annual PM
                        <E T="52">2.5</E>
                         standard with a level of 9.0 µg/m
                        <SU>3</SU>
                         would be expected to provide substantial improvements in public health compared to the current annual standard, including for at-risk groups such as children, older adults, people with preexisting conditions, minority populations, and low SES populations.

                    <P>
                        Consistent with his conclusions on the need for revision of the current annual standard, in reaching a decision on level, the Administrator places the most weight on information from epidemiologic studies. In so doing, the Administrator notes that these studies provide consistent evidence of positive and statistically significant associations between long- and short-term exposure to PM
                        <E T="52">2.5</E>
                         and mortality and morbidity (88 FR 5624, January 27, 2023). The Administrator recognizes that placing weight on the information from the epidemiologic studies allows for examination of the entire population, including those that may be at comparatively higher risk of experiencing a PM
                        <E T="52">2.5</E>
                        -related health effects (

                         children, older adults, minority populations) (88 FR 5624, January 27, 2023). The Administrator also recognizes that recent epidemiologic studies continue to support a no-threshold relationship, meaning that there is no “bright line” below which no effects have been found. These studies also support a linear relationship between health effects and PM
                        <E T="52">2.5</E>
                         exposures at PM

                        , with some recent studies providing evidence for either a sublinear, linear, or supralinear relationship at these lower concentrations (U.S. EPA, 2019a, section 11.2.4; U.S. EPA, 2022a, section 2.2.3.2; 88 FR 5625, January 27, 2023).

                        As at the time of proposal, the Administrator notes that some recent epidemiologic studies have adopted a broad range of approaches to examine confounding and the results of those examinations support the robustness of reported associations seen in epidemiologic studies. These include studies that employ alternative methods for confounder control and studies that evaluate the uncertainty related to exposure measurement error, both of which continue to support associations between PM
                        <E T="52">2.5</E>
                         exposures and health effects while taking approaches to address uncertainties.

                    <P>
                        In considering the epidemiologic evidence, the Administrator judges that, in reaching his decision on an appropriate level for the annual standard that will protect public health with an adequate margin of safety, in the absence of any discernible population-level thresholds, and in recognizing the need to weigh uncertainties associated with the epidemiologic evidence, it is most appropriate to examine where the evidence of associations observed in the 
                        <PRTPAGE P="16279"/>
                        epidemiologic studies is strongest and, conversely, to place less weight where he has less confidence in the associations observed in the epidemiologic studies. As at the time of proposal, the Administrator notes that in previous reviews, evidence-based approaches noted that the evidence of an association in any epidemiologic study is “strongest at and around the long-term average where the data in the study are most concentrated” (78 FR 3140, January 15, 2013). Given this, these approaches focused on identifying standard levels near or somewhat below long-term mean concentrations reported in key epidemiologic studies. These approaches were supported by previous CASAC advice as well as the CASAC's advice in their review of the 2021 draft PA as a part of this reconsideration.
                    </P>
                    <P>Additionally, the Administrator acknowledges that in the 2020 final action, the then-Administrator decided to retain the standard based in part on concerns about placing reliance on the epidemiologic studies and his judgment that even if he did rely on them, the majority of the studies had means or medians, as well as the mean of all of the key study-reported means or medians, above the level of the current annual standard. However, after considering the evidence, the advice of CASAC, and public comments the Administrator judges that this approach is insufficient to protect public health with an adequate margin of safety. The Administrator's decision to reach a different judgment about the appropriate level of the annual standard reflects the updated and expanded scientific record available to the Administrator in this reconsideration, as well as the additional advice from the CASAC and the public comments based on this newly available information. In addition, the Administrator observes the decision in this action to place weight on the epidemiologic studies, and to revise the annual primary standard to a level below the lowest long-term mean in the U.S.-based epidemiologic studies, is consistent with the EPA's past practice in PM NAAQS reviews.</P>
                    <P>In this reconsideration, the Administrator is considering the scientific record which has been expanded and updated since the 2020 final action, as well as the additional advice from the CASAC and the public comments that are based on the newly available information that expands upon the information previously available. In addition, the Administrator is exercising his judgment about how to interpret and weigh the expanded evidence in a way that is more consistent with the approaches used in prior PM NAAQS reviews. As a result, the Administrator has concluded on reconsideration that the level of the primary annual standard is not adequate and should be revised to protect public health with an adequate margin of safety.</P>

                         He notes that in previous PM NAAQS reviews (including the 1997, 2006 and 2012 reviews), evidence-based approaches focused on identifying standard levels near or somewhat below long-term mean concentrations reported in key long- and short-term epidemiologic studies. These approaches were supported by the CASAC in previous reviews and were supported in this reconsideration by the CASAC in their review of the 2021 draft PA. In considering the available scientific evidence to inform such an approach, the Administrator notes the strength of the epidemiologic evidence which includes multiple studies that consistently report positive associations for short- and long-term PM
                        <E T="52">2.5</E>
                         exposure and mortality and cardiovascular effects. Some available studies also use a variety of statistical methods to control for confounding bias and report similar associations, which further supports the broader body of epidemiologic evidence for both mortality and cardiovascular effects. Additionally, he notes that recent epidemiologic studies available for consideration in reaching his final decision strengthen support for health effect associations at PM
                        <E T="52">2.5</E>
                         concentrations lower than in those evaluated in epidemiologic studies available at the time of previous reviews. The Administrator does recognize, however, that while these epidemiologic studies evaluate associations between distributions of ambient PM
                        <E T="52">2.5</E>
                         concentrations and health outcomes, they do not identify the specific exposures that led to the reported effects. As such, he notes that there is no specific point in the air quality distribution of any epidemiologic study that represents a “bright line” at and above which effects have been observed and below which effects have not been observed. The Administrator further notes that the epidemiologic studies provide the strongest support for reported health effect associations for this middle portion of the PM
                        <E T="52">2.5</E>
                         air quality distribution, which corresponds to the bulk of the underlying data, rather than the extreme upper or lower ends of the distribution, and concludes that the long-term study-reported means from both long- and short-term studies provide the strongest support for reported health effect associations in epidemiologic studies. For these reasons, as described in the proposal and in responding to public comments in section II.B.3 above, the Administrator concludes that it is appropriate to continue to employ an approach that focuses on the mean PM
                        <E T="52">2.5</E>
                         concentrations from the key epidemiologic studies to inform his conclusions regarding the appropriate level for the primary annual PM

                        In adopting such an approach, the Administrator considers the long-term mean concentrations reported in two types of key epidemiologic studies: (1) Monitor-based studies 
                        <SU>114</SU>
                        <FTREF/>
                         (epidemiologic studies that used ground-based monitors to estimate exposure, similar to approaches used in past reviews), and (2) hybrid modeling-based studies 
                        <SU>115</SU>
                        <FTREF/>
                         (epidemiologic studies that used hybrid modeling approaches and apply aspects of population weighting to estimate exposures). In reaching conclusions regarding the level of a standard that would provide requisite protection with an adequate margin of safety, the Administrator recognizes that he must use his judgment regarding the appropriate weight to place on the available evidence and technical information, including uncertainties. As shown in Figures 1 and 2 above, for the key U.S. monitor-based epidemiologic studies, 
                        <PRTPAGE P="16280"/>
                        the study-reported mean concentrations range from 9.9-16.5 μg/m
                        <SU>3</SU>
                        , and for the key U.S. hybrid modeling-based epidemiologic studies, the mean concentrations range from 9.3-12.2 μg/m
                        <SU>3</SU>
                        . The Administrator also recognizes that, in their review of the 2021 draft PA, both the majority and minority of the CASAC emphasized the epidemiologic studies in support of their recommendations for the level of the annual standard, but they weighed the studies in different ways (Sheppard, 2022a, p. 16-17 of consensus responses).

                        Based on this information, and in considering the CASAC's advice in their review of the 2021 draft PA, the Administrator judges that it is appropriate to set the level of the primary PM
                        <E T="52">2.5</E>
                         standard at least as low as the lowest mean PM

                        <SU>3</SU>
                        . The Administrator additionally notes that setting the annual standard level at 9.0 µg/m
                        <SU>3</SU>
                        , which is below the lowest study-reported mean PM

                         concentration of 9.3 µg/m
                        <SU>3</SU>
                        , would be expected to shift the distribution of PM

                         concentrations in an area such that the area's highest monitor would generally be at or below 9.0 µg/m
                        <SU>3</SU>
                         annually, when meeting the annual standard. In this situation, the resulting average or mean PM

                         concentration for the entire area (measured across a number of monitors) would be even further below the study-reported means,

                        As noted above, however, the Administrator must exercise his judgment regarding the appropriate weight to place on the available scientific evidence and quantitative information, including uncertainties, in determining what level of the annual standard is sufficient to protect public health with an adequate margin of safety. In so doing, he considers other information available in this reconsideration to inform his judgments, including study-reported PM
                        <E T="52">2.5</E>
                         concentrations at lower percentiles in key epidemiologic studies, supplemental information from other types of epidemiologic studies, study-reported PM
                        <E T="52">2.5</E>
                         concentrations from key Canadian epidemiologic studies, and the results from the quantitative risk assessment.

                    <P>
                        In weighing the evidence in considering the requisite level of the annual standard, the Administrator also takes into account additional information from the key long- and short-term U.S. epidemiologic studies available that provide study-reported PM
                        <E T="52">2.5</E>
                         concentrations below the mean and, in particular, the subset of epidemiologic studies that report 25th and 10th percentile concentrations. Consistent with his proposed conclusions, as well as the CASAC's advice in their review of the 2021 draft PA and public comments, the Administrator judges that it is appropriate to place some weight on these lower percentiles in reaching his conclusions on the level of the primary annual standard. There are six key U.S. epidemiologic studies that report information on other percentiles (
                        <E T="03">e.g.,</E>
                         10th and 25th percentiles of PM

                         concentrations or 10th and 25th percentiles of PM
                        <E T="52">2.5</E>
                         concentrations associated with health events) that are below the mean.
                        <SU>117</SU>
                        <FTREF/>
                         In considering the information from these studies, the Administrator first notes that the three older, monitor-based studies that report lower percentiles of PM
                        <E T="52">2.5</E>
                         concentrations have smaller cohort sizes than the three hybrid model-based studies. Thus, the Administrator recognizes that the older, monitor-based studies had a relatively smaller portion of the health events that were observed in the lower part of the air quality distribution because of the generally smaller size of the cohorts. He further notes that the recent hybrid model-based studies have larger cohort sizes than the older, monitor-based studies, and therefore, have more health events in the lower part of the air quality distribution. Because of the larger cohort sizes and having a larger portion of health events that are observed across the air quality distribution, the Administrator has more confidence in the magnitude and significance of the associations in the lower parts of the air quality distribution for the recent, hybrid model-based studies compared to the older, monitor-based studies. Given this, the Administrator judges that it is appropriate to place weight on the 25th percentile concentrations reported in the recently available hybrid model-based studies in reaching his conclusions regarding the appropriate level for the primary annual PM
                        <E T="52">2.5</E>
                         standard. However, the Administrator also recognizes that his confidence in the magnitude and significance in the reported concentrations, and their ability to inform decisions on the appropriate level of the annual standard, starts to diminish at percentiles that are even further below the mean and the 25th percentile. For these reasons, the Administrator places weight on the reported 25th percentiles concentrations in the recent hybrid model-based studies, rather than the reported 10th percentile concentrations, in reaching his conclusions regarding the appropriate level for the primary annual PM
                        <E T="52">2.5</E>

These studies are Di et al. (2017b) and Wang et al. (2017) and the reported 25th percentile concentration is 9.1 µg/m

                         In considering these studies, the Administrator concludes that it is appropriate to place weight on the 25th percentile concentrations of these newer hybrid model-based studies (of 9.1 µg/m
                        <SU>3</SU>
                        ) such that setting the level of the standard near these 25th percentile concentrations would provide requisite protection. The Administrator observes that an annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         would be near the reported 25th percentile concentrations in these studies.

                             There is a third hybrid model-based study, as described in the 2022 PA and in section II.B.3 above in responding to public comments, but it is not referenced here because it reports a 25th percentile PM
                            <E T="52">2.5</E>
                             concentration based on the 25th percentile of health events that occur in the study (Di et al., 2017a) rather than report the 25th percentile based on air quality concentrations.

                    <P>
                        As at the time of proposal, the Administrator also takes note of the study-reported long-term mean PM
                        <E T="52">2.5</E>
                         concentrations in long- and short-term Canadian epidemiologic studies, which ranged from 6.9 to 13.3 µg/m
                        <SU>3</SU>
                         for monitor-based studies and 5.9 to 9.8 µg/m
                        <SU>3</SU>
                         for hybrid model-based studies. While the Administrator notes that these studies provide additional support for associations between PM
                        <E T="52">2.5</E>
                         concentrations and health effects, he is also mindful that there are important differences between the exposure environments in the U.S. and Canada and that interpreting the data (
                        <E T="03">e.g.,</E>
                         study-reported mean concentrations) 
                        <PRTPAGE P="16281"/>
                        from the Canadian studies in the context of a U.S.-based standard may present challenges in directly and quantitatively informing decisions regarding potential alternative levels of the annual standard. For example, in terms of people per square kilometer, the U.S. population density is nearly 10 times in the contiguous U.S. compared to Canada. As described in more detail in responding to public comments in section II.B.3 above, in this reconsideration, the Administrator recognizes that this difference in population density between the U.S. and Canada is more apparent than in previous reviews because the studies available in this reconsideration use different approaches than those previously available. In the 2012 review, the available Canadian epidemiologic studies used population-weighting and focused on urban areas where monitors were available and population densities were more comparable with those in the U.S., and at that time, the U.S. and Canadian studies reported similar mean PM
                        <E T="52">2.5</E>
                         concentrations. However, in this reconsideration, the Administrator takes note that for the new Canadian epidemiologic studies: (1) The Canadian monitor-based studies available in this reconsideration do not apply population weighting as the previously available studies did; and (2) some of the studies now use hybrid modeling approaches for estimating exposure. The Administrator recognizes that these differences are important to consider in reaching conclusions on how these Canadian epidemiologic studies should be interpreted regarding decisions on the requisite level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. Specifically, the Administrator notes that the more recent Canadian studies that use hybrid modeling incorporate larger portions of the country, and therefore include more rural areas. The more rural areas that are included in the study using the hybrid modeling approaches, the more important it is to consider how the population densities and exposure environments differ between the U.S. and Canada. Additionally, the Administrator notes that for hybrid modeling-based studies there is less certainty in PM
                        <E T="52">2.5</E>
                         exposure estimates in more rural areas, which are further from air quality monitors and where PM
                        <E T="52">2.5</E>
                         concentrations in the ambient air tend to be lower. For these hybrid model-based studies, the portion of the rural areas that are contributing to the study-reported mean PM
                        <E T="52">2.5</E>
                         concentrations in these studies is unclear. For these reasons, the Administrator concludes that it is important to consider the differences between the population exposures in the U.S. and Canadian study areas and how these differences influence the interpretation of the epidemiologic study results.

                    <P>
                        Thus, the Administrator considers the Canadian studies to inform his judgments on what level for the annual standard is requisite in light of the limitations and challenges presented. The Administrator also recognizes that the majority of the CASAC in their review of the 2021 draft PA, as well as a number of public commenters, place weight on the Canadian epidemiologic studies in recommending that the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard be revised to 8-10 µg/m
                        <SU>3</SU>
                        . The Administrator further notes while the majority of the CASAC advised the EPA to consider the Canadian studies in revising the annual standard level to within the range of 8.0-10.0 µg/m
                        <SU>3</SU>
                        , they did not advise the EPA to set the annual standard level below the study-reported means from those studies. Given these considerations, the Administrator judges that it is appropriate to set the level of annual standard within the range of 8-10 µg/m
                        <SU>3</SU>
                         to be consistent with the majority of the CASAC's advice in their consideration of these studies.

                    <P>
                        The Administrator also recognizes that information from epidemiologic studies that included analyses that restrict annual average PM
                        <E T="52">2.5</E>
                         concentrations to concentrations below the level of the current annual standard can be useful for informing conclusions regarding the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. In so doing, he particularly notes the two key U.S. epidemiologic studies (Di et al., 2017b and Dominici et al., 2019) that restrict annual average PM
                        <E T="52">2.5</E>
                         concentrations to less than 12 µg/m
                        <SU>3</SU>
                         and report positive and statistically significant associations with all-cause mortality and mean PM
                        <E T="52">2.5</E>
                         concentrations of 9.6 µg/m
                        <SU>3</SU>
                        . He also considers these results along with the uncertainties and limitations associated with studies that restricted analyses below certain PM
                        <E T="52">2.5</E>
                         concentrations. As described in responding to comments in section II.B.3 above, uncertainties associated with how the studies exclude PM
                        <E T="52">2.5</E>
                         concentrations from the analyses (
                        <E T="03">e.g.,</E>
                         at what spatial resolution are concentrations being excluded), make it difficult to understand how to interpret the results of the restricted analyses in the context of the approach employed in this reconsideration, which takes into consideration the relationship between mean PM
                        <E T="52">2.5</E>
                         concentrations and design values.

                    <P>
                        The Administrator also recognizes that, in their review of the 2021 draft PA, the CASAC noted that epidemiologic studies that restrict analyses below certain PM
                        <E T="52">2.5</E>
                         concentrations represent one area for which the evidence has expanded in this reconsideration, stating that these studies provide support for mortality effects at concentrations below the current PM NAAQS (Sheppard, 2022a, p. 5 of consensus responses). In their recommendations on alternative levels for the primary annual PM
                        <E T="52">2.5</E>
                         standard, the majority of the CASAC cited to studies that restrict PM
                        <E T="52">2.5</E>
                         concentrations to below 12 µg/m
                        <SU>3</SU>
                         as a part of their rationale for supporting a level within the range of 8-10 µg/m
                        <SU>3</SU>
                         (Sheppard, 2022a p. 16 of consensus responses). Additionally, the Administrator notes that some members of the CASAC, in their review of the 2019 draft PA, concluded that the epidemiologic studies that restrict analyses below 12 µg/m
                        <SU>3</SU>
                         and show positive associations with health effects, along with other aspects of the scientific evidence, provide support for their conclusion that the primary annual PM
                        <E T="52">2.5</E>
                         standard is not adequate (Cox, 2019b, p. 9 of consensus responses). Furthermore, the Administrator takes note of public commenters who also noted that the epidemiologic studies that restrict PM
                        <E T="52">2.5</E>
                         concentrations to below the current standard provide support, along with the other available information, for lowering the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. In considering the studies that include restricted analyses, along with the CASAC's advice and public comments on these types of studies, the Administrator concludes that, although there are inherent uncertainties associated with this limited body of evidence, these studies that apply restricted analyses provide support for serious effects (
                        <E T="03">e.g.,</E>
                         mortality) at concentrations below 10.0 µg/m
                        <SU>3</SU>
                        . Given this, the Administrator concludes that it is appropriate to place some weight on these studies, and in doing so, notes that a standard level of 9.0 µg/m
                        <SU>3</SU>
                         would be below the reported mean PM
                        <E T="52">2.5</E>
                         concentrations of 9.6 µg/m
                        <SU>3</SU>
                         in these studies and would, thus, be expected to provide protection against exposures related to these reported mean concentrations.

                    <P>
                        The Administrator also takes into consideration recent U.S. accountability studies, which assess the health effects associated with actions that improve air quality (
                        <E T="03">e.g.,</E>
                         air quality policies or implementation of an intervention). These types of studies can also reduce uncertainties related to residual confounding of temporal and spatial factors (U.S. EPA, 2022a, p. 3-25). The 
                        <PRTPAGE P="16282"/>
                        Administrator notes that in the 2020 review, the available accountability studies had “starting” annual average PM
                        <E T="52">2.5</E>
                         concentrations (
                        <E T="03">i.e.,</E>
                         mean concentration prior to reductions being evaluated) from 13.2-31.5 µg/m
                        <SU>3</SU>
                        , and the then-Administrator cited the lack of accountability studies in areas where the “starting” concentration met the current primary PM
                        <E T="52">2.5</E>
                         standards as part of his rationale for retaining the standards. As at the time of proposal, the current Administrator notes that in three studies newly available in this reconsideration and assessed in the ISA Supplement, prior to implementation of the policies, mean PM
                        <E T="52">2.5</E>
                         concentrations in these studies were below the level of the current annual standard level (12.0 µg/m
                        <SU>3</SU>
                        ) and ranged from 10.0 µg/m
                        <SU>3</SU>
                         to 11.1 µg/m
                        <SU>3</SU>
                        . These studies report positive and significant associations between mortality and cardiovascular morbidity and reductions in ambient PM
                        <E T="52">2.5</E>
                         following the implementation of a policy (Henneman et al., 2019; Corrigan et al., 2018; Sanders et al., 2020a; 88 FR 5627, January 27, 2023). These studies suggest that public health improvements may occur following the implementation of a policy that reduces annual average PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current standard of 12.0 µg/m
                        <SU>3</SU>
                        . The Administrator recognizes that in their review of the 2021 draft PA, the CASAC noted that the availability of recent accountability studies was one area where the evidence had been strengthened and that the studies assessed in the ISA Supplement provide evidence of mortality effects at annual average PM
                        <E T="52">2.5</E>
                         concentrations below the current NAAQS (Sheppard, 2022a, p. 5 of consensus responses). The Administrator recognizes that the CASAC also concluded that, along with other lines of evidence, the accountability studies with starting concentrations below the levels of the current standards are appropriate to consider for informing conclusions on alternative standard levels (Sheppard, 2022a, p. 13 of consensus responses). The Administrator also notes the advice of the CASAC in their review of the 2019 draft ISA, where they suggested that accountability studies be taken into account and such studies provide potentially crucial information about whether and how much decreasing PM
                        <E T="52">2.5</E>
                         causes decreases in future health effects, which reflects the primary purpose of the NAAQS (Cox, 2019b, p. 8 and 10 of consensus responses). The Administrator also notes that in their review of the 2019 draft ISA, some members of the CASAC cautioned against placing more weight on the data from accountability studies based on the methodological limitations of the studies (Cox, 2019b, p. 8 of consensus responses). The Administrator notes that the CASAC did not explicitly cite to accountability studies in their reviews of the 2019 draft PA or 2021 draft PA as support for their recommendations on the adequacy of the primary annual PM
                        <E T="52">2.5</E>
                         standard or potential alternative standard levels. A number of public commenters who support revising the level of the standard to 8 µg/m
                        <SU>3</SU>
                         cite these accountability studies, along with the broader evidence base, as support for a more protective standard. The Administrator, in considering the evidence, the advice from the CASAC, and public comment, first recognizes that accountability studies are just one line of evidence to be considered in the broader evaluations of the information available to inform conclusions on the level of the standard. In so doing, he notes that public health improvements may occur following the implementation of a policy that reduces annual average PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current standard of 12.0 µg/m
                        <SU>3</SU>
                        , and potentially below the lowest “starting” concentrations in these studies of 10.0 µg/m
                        <SU>3</SU>
                        . However, the Administrator concludes that the limited number of accountability studies provide limited information for informing decisions on the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard but recognizes that these studies provide supplemental information for consideration along with the full body of evidence. Taken together, the Administrator notes a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         is at or below the lowest starting concentration of these accountability studies (
                        <E T="03">i.e.,</E>
                         10.0 µg/m
                        <SU>3</SU>
                        ), and judges that it is appropriate to place some weight on these studies, particularly for informing his public policy judgments regarding an adequate margin of safety.

                    <P>
                        In addition to his consideration of and conclusions regarding the available scientific evidence, the Administrator also considers the results of the quantitative risk assessment to inform his conclusions regarding the appropriate level for the primary annual PM
                        <E T="52">2.5</E>
                         standard. The Administrator recognizes that the risk estimates can help to place the evidence for specific health effects into a broader public health context, but should be considered along with the inherent uncertainties and limitations of such analyses when informing judgments about the potential for additional public health protection associated with PM
                        <E T="52">2.5</E>
                         exposure and related health effects. The Administrator recognizes that the overall risk assessment estimates suggest that the current primary annual PM
                        <E T="52">2.5</E>
                         standard could allow a substantial number of PM

                        -associated deaths in the U.S. The Administrator also recognizes that the CASAC concurred with the 2021 draft PA's assessment that meaningful risk reductions will result from lowering the annual PM

                        Additionally, with respect to the results of the quantitative risk assessment, the Administrator recognizes that the 2022 PA also provides information on the distribution of concentrations associated with the estimated mortality risk at each alternative standard level assessed (U.S. EPA, 2022b, sections 3.4.2.2 and 3.6.2.2, Figure 3-18 and 3-19). When meeting an annual standard of 9.0 µg/m
                        <SU>3</SU>
                         at the design value monitor, the exposure concentrations within an area are estimated to be below 9 µg/m
                        <SU>3</SU>
                        , with the majority of those exposures being at concentrations of below 8 µg/m
                        <SU>3</SU>
                        . The Administrator notes that this range of concentrations is below the lowest means in the key long- and short-term epidemiologic studies (concentrations at which the evidence is the strongest in supporting an association between exposure to PM
                        <E T="52">2.5</E>
                         and adverse health effects observed in the key epidemiologic studies available in this reconsideration). Thus, the Administrator concludes that the results of the quantitative risk assessment suggest that a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         is estimated to reduce PM
                        <E T="52">2.5</E>
                         exposures to fall within the range of concentrations in which there is the most confidence in the associations and thus, confidence that estimated risk reductions will actually occur.

                    <P>
                        The Administrator also notes the information provided by the quantitative risk assessment on the distribution of concentrations associated with the estimated mortality risk for a higher annual standard level of 10.0 µg/m
                        <SU>3</SU>
                         and a lower standard level of 8.0 µg/m
                        <SU>3</SU>
                         (U.S. EPA, 2022b, sections 3.4.2.2 and 3.6.2.2, Figure 3-18 and 3-19). The Administrator finds that, for an annual standard level of 10.0 µg/m
                        <SU>3</SU>
                        , the quantitative risk assessment estimates that the standard would allow multiple exposures at concentrations above the lowest means in the key epidemiologic studies, and therefore, calls into question whether a standard level of 10.0 µg/m
                        <SU>3</SU>
                         would provide enough public health protection. Additionally, the Administrator also finds that, for a lower annual standard level of 8.0 µg/
                        <PRTPAGE P="16283"/>
                        m
                        <SU>3</SU>
                        , the quantitative risk assessment estimates the exposure concentrations to be below 8 µg/m
                        <SU>3</SU>
                        , with the majority of those exposures being at concentrations of below 7 µg/m
                        <SU>3</SU>
                        . The Administrator observes that the majority of exposure concentrations under this air quality scenario are estimated to fall outside of the range of concentrations in which he has the most confidence in the associations and that the additional risk reductions will actually occur.

                    <P>
                        Recognizing and building upon the above considerations and judgments, and with consideration of advice from the CASAC and public comment, the Administrator concludes that the current body of scientific evidence and quantitative risk assessment support his judgment that the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard should be revised to a level of 9.0 µg/m
                        <SU>3</SU>
                        . Revising the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard will, in the Administrator's judgment, provide requisite public health protection with an adequate margin of safety.
                    </P>
                    <P>
                        The Administrator recognizes that placing weight on the information from the epidemiologic studies allows for examination of the entire population, including those that may be at comparatively higher risk of experiencing a PM
                        <E T="52">2.5</E>
                        -related health effects (
                        <E T="03">e.g.,</E>
                         children, older adults, minority populations) (88 FR 5624, January 27, 2023). In considering the epidemiologic evidence, the Administrator judges that, in reaching his decision on an appropriate level for the annual standard that will protect public health with an adequate margin of safety, in the absence of any discernible population-level thresholds, and in recognizing the need to weigh uncertainties associated with the epidemiologic evidence, it is most appropriate to examine where the evidence of associations observed in the epidemiologic studies is strongest and, conversely, to place less weight where he has less confidence in the associations observed in the epidemiologic studies. The Administrator notes that in previous reviews, evidence-based approaches noted that the evidence of an association in any epidemiologic study is “strongest at and around the long-term average where the data in the study are most concentrated” (78 FR 3140, January 15, 2013). These approaches were supported by previous CASAC advice as well as the CASAC's advice in their review of the 2021 draft PA as a part of this reconsideration. Given this, the Administrator notes that in revising the annual PM
                        <E T="52">2.5</E>
                         standard to a level of 9.0 µg/m
                        <SU>3</SU>
                        , he is setting the standard at a level below the long-term mean PM
                        <E T="52">2.5</E>
                         concentrations in the key long- and short-term epidemiologic studies, including the lowest study reported mean of 9.3 µg/m
                        <SU>3</SU>
                        , following an approach that is consistent with previous PM NAAQS reviews. The Administrator additionally notes that air quality analyses in the 2022 PA demonstrate that areas meeting a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                         would be expected to shift the distribution of PM
                        <E T="52">2.5</E>
                         exposure concentrations in an area such that the area's highest monitor would generally be at or below 9.0 µg/m
                        <SU>3</SU>
                         annually, and most of the resulting PM
                        <E T="52">2.5</E>
                         concentrations across the area would be even further below the study-reported means.
                        <E T="51">119 120</E>
                        <FTREF/>
                         Thus, a standard level of 9.0 µg/m
                        <SU>3</SU>
                         is expected to provide sufficient protection not only in areas where the highest allowable concentration would be located (
                        <E T="03">i.e.,</E>
                         near design value monitors) but also in other parts of the area where PM
                        <E T="52">2.5</E>
                         concentrations would be expected to be maintained even lower.

                             Analyses in the 2022 PA suggest that the highest monitored value would be expected to be greater than the study-reported mean values by 10-20% for monitor-based studies and 15-18% for hybrid modeling studies that apply aspects of population weighting (U.S. EPA, 2022b, section 2.3.3.2.4).

                             The risk assessment in the 2022 PA used air quality adjustments to simulate just meeting the current primary PM

                             standards, as well as alternative standard levels (U.S. EPA, 2022b, section 3.4.1.4 and Appendix C, section C.1.4).

                    <P>
                        Furthermore, the Administrator recognizes the CASAC's advice in their review of the 2021 draft PA, as well as public comments, that weight should be placed on study-reported PM
                        <E T="52">2.5</E>
                         concentrations that are somewhat below the mean, particularly for some of the newer epidemiologic studies with larger cohort sizes. In weighing uncertainties associated with using these data to inform a revised annual standard level, as well as noting the limited studies for which this information is available, the Administrator judges that some weight should be placed on these data, but they should not receive the same weight as the study-reported mean concentrations. Thus, the Administrator concludes that it would be appropriate to set the annual standard level near the 25th percentile PM
                        <E T="52">2.5</E>
                         concentrations in the two newer key epidemiologic studies for which these values were reported. In doing so, the Administrator notes that a decision to revise the annual standard to 9.0 µg/m
                        <SU>3</SU>
                         would set a level of the standard near and somewhat below the reported 25th percentile PM
                        <E T="52">2.5</E>
                         concentrations of 9.1 µg/m
                        <SU>3</SU>
                         in these two more recent hybrid model-based studies.

                    <P>
                        The Administrator also takes note of the study-reported long-term mean PM
                        <E T="52">2.5</E>
                         concentrations in the key Canadian epidemiologic studies. While the Administrator notes that these studies provide additional support for associations between PM
                        <E T="52">2.5</E>
                         concentrations and health effects, he is also mindful that there are important differences between the exposure environments in the U.S. and Canada that affect interpretation of the data in the context of informing decisions regarding potential alternative levels of the annual standard. The Administrator also recognizes that the majority of the CASAC in their review of the 2021 draft PA, as well as a number of public commenters, placed weight on the Canadian epidemiologic studies in recommending that the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard be revised to 8-10 µg/m
                        <SU>3</SU>
                        . The Administrator notes that a decision to revise the annual standard to 9.0 µg/m
                        <SU>3</SU>
                         would set the level of the standard within the range of levels recommended by the majority of CASAC in their consideration of these studies.
                    </P>
                    <P>
                        Additionally, the Administrator also considers the information provided by epidemiologic studies that use restricted analyses, as well as accountability studies. With respect to the restricted analyses, the Administrator, in considering the CASAC's advice in their review of the 2021 draft PA and many public comments on these types of studies, concludes that, although there are inherent uncertainties associated with this limited body of evidence, the studies that apply restricted analyses provide support for serious effects (
                        <E T="03">e.g.,</E>
                         mortality) at concentrations below 10.0 µg/m
                        <SU>3</SU>
                        . Additionally, in considering accountability studies, the Administrator concludes that while the small number of these studies provide limited information for informing decisions on the appropriate level of the primary annual PM
                        <E T="52">2.5</E>
                         standard, these studies provide supplemental information for consideration along with the full body of evidence. The Administrator further notes that these studies suggest that public health improvements may occur following the implementation of a policy that reduces annual average PM
                        <E T="52">2.5</E>
                         concentrations below the level of the current standard of 12.0 µg/m
                        <SU>3</SU>
                        , and potentially below the lowest “starting” concentrations in these studies of 10.0 µg/m
                        <SU>3</SU>
                        . Taken together, the Administrator judges that it is appropriate to place some weight on these types of studies, particularly for informing his public policy judgments regarding an adequate margin 
                        <PRTPAGE P="16284"/>
                        of safety, and notes that a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         is below the lowest starting concentration of the accountability studies (
                        <E T="03">i.e.,</E>
                         10.0 µg/m
                        <SU>3</SU>
                        ), and below the concentration at which studies that apply restricted analyses provide support for serious effects (
                        <E T="03">i.e.,</E>
                         9.6 µg/m

                    <P>
                        The Administrator also judges that the results of the quantitative risk assessment provide support for a primary annual PM
                        <E T="52">2.5</E>
                         standard with a level of 9.0 µg/m

                         at the design value monitor, with the majority of those exposures being at concentrations below 8 µg/m
                        <SU>3</SU>
                        . Thus, the Administrator notes that an annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         would be expected to provide protection from exposures where he has the greatest confidence in the associations between health effects and PM

                        <SU>3</SU>
                        , which is below concentrations at which the evidence is the strongest in supporting an association between exposure to PM

                         and adverse health effects observed in the key epidemiologic studies available in this reconsideration, would be expected to shift the distribution of PM

                         would provide requisite protection with adequate margin of safety, for all populations, including those most at-risk.

                    <P>In reaching this conclusion, the Administrator recognizes that in establishing primary standards under the Act that are requisite to protect public health with an adequate margin of safety, he is seeking to establish standards that are neither more nor less stringent than necessary for this purpose. The Act does not require that primary standards be set at a zero-risk level or to protect the most sensitive individual, but rather at a level that avoids unacceptable risks to public health. In this context, the Administrator's conclusion is that revised primary annual standard, in conjunction with the 24-hour standard, provides the appropriate degree of protection, and that more or less stringent standards would not be requisite.</P>
                    <P>
                        In considering the requirement for an adequate margin of safety, the Administrator notes that the determination of what constitutes an adequate margin of safety is expressly left to the judgment of the EPA Administrator.

Consistent with past practice and long-standing judicial precedent, and as described in this section, the Administrator takes the need for an adequate margin of safety into account as an integral part of his decision making on a standard.

                    <P>
                        Given all of the evidence and information discussed above, the Administrator judges that a standard with a level of 9.0 µg/m
                        <SU>3</SU>
                         is requisite to protect public health with an adequate margin of safety. In so doing, he first recognizes that a less stringent standard would allow the occurrence of higher long- and short-term PM
                        <E T="52">2.5</E>
                         concentrations at a level at or above the mean PM
                        <E T="52">2.5</E>
                         concentrations in key U.S. epidemiologic studies. That is, a less stringent standard would be expected to allow more PM
                        <E T="52">2.5</E>
                         exposures at concentrations at or above which the key U.S. epidemiologic studies have reported associations between mean PM
                        <E T="52">2.5</E>
                         concentrations and serious health effects and would deviate from some past approaches for selecting the appropriate level of the annual standard. A less stringent standard would also not provide requisite protection with an adequate margin of safety against PM
                        <E T="52">2.5</E>
                         exposures in the lower percentiles of the air quality distribution (
                        <E T="03">i.e.,</E>
                         25th percentile) for which associations with health effects have been observed in a limited number of epidemiologic studies. Furthermore, the Administrator notes that the primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards, together, are intended to provide public health protection against the full distribution of long- and short-term PM
                        <E T="52">2.5</E>
                         exposures. As noted above, the Administrator recognizes that the changes in PM
                        <E T="52">2.5</E>
                         air quality designed to meet a less stringent annual standard would likely result in higher exposures across the distribution of air quality, including both higher average (or typical) concentrations as well as higher short-term peak PM
                        <E T="52">2.5</E>
                         concentrations. Taking into consideration both the full evidence base for associations of PM
                        <E T="52">2.5</E>
                         with mortality and other adverse health effects, including the reported mean PM
                        <E T="52">2.5</E>
                         concentrations from key long- and short-term U.S. epidemiologic studies, information from epidemiologic studies that report 25th percentile PM
                        <E T="52">2.5</E>
                         concentrations, supplemental information from other epidemiologic studies (

                         epidemiologic studies that use restricted analyses, accountability studies, and Canadian epidemiologic studies), and the results of the risk assessment, as well as the advice from the CASAC and public comments, the Administrator concludes that a less stringent standard would allow risks of mortality and other adverse health effects that are too great, and thus would not provide sufficient protection for public health as required by the CAA.
                    </P>
                    <P>
                        Additionally, in considering a less stringent standard, the Administrator recognizes that through its control of long- and short-term PM
                        <E T="52">2.5</E>
                         concentrations, the annual standard provides a margin of safety for less well-studied exposure levels and population groups for which the evidence is limited or lacking. In so doing, he recognizes that our understanding of the relationships between the presence of a pollutant in ambient air and associated health effects is based on a broad body of information encompassing not only more established aspects of the evidence, such as the conclusion that long- and short-term exposures to PM
                        <E T="52">2.5</E>
                         are causally related to mortality and cardiovascular effects and likely to be causally related to respiratory effects, but also aspects with which there may be substantial uncertainty. In particular, the Administrator notes that there are other categories of effects with causality determinations that are suggestive of, but not sufficient to infer, a causal 
                        <PRTPAGE P="16285"/>
                        relationship between PM
                        <E T="52">2.5</E>
                         exposure and health outcomes. These include, but are not limited t,o short-term exposure and nervous system effects, as well as long- and short-term exposure and pregnancy and birth outcomes, where the evidence is less certain but which represent potentially substantial additional risk to public health from exposure to PM
                        <E T="52">2.5</E>
                        . He recognizes the CAA requirement that requires primary standards to provide an adequate margin of safety was intended to address uncertainties associated with inconclusive scientific and technical information as well as to provide a reasonable degree of protection against hazards that research has not yet identified and in his judgment, the primary NAAQS must be set at a level that is adequately protective against these and other effects which research has not yet identified. Thus, even if the Administrator had somewhat greater concerns about the possibility of confounding, error and bias in the epidemiologic studies, which reduced his confidence in finding that PM
                        <E T="52">2.5</E>
                         is causally related to mortality and cardiovascular effects, he would still find it appropriate to set the primary NAAQS below the means of key U.S. epidemiologic studies given the strength of the evidence providing support for the association, as well as additional evidence linking PM
                        <E T="52">2.5</E>
                         to other endpoints of substantial public health concern, and the need to protect public health with an adequate margin of safety. In considering the uncertainties in both the epidemiologic evidence and the controlled human exposures studies, the Administrator recognizes that collectively, the health effects evidence generally reflects a continuum, consisting of levels at which scientists generally agree that health effects are likely to occur, through lower levels at which the likelihood and magnitude of the response become increasingly uncertain. In light of these uncertainties, the Administrator recognizes that the CAA requirement that primary standards provide an adequate margin of safety, as summarized in section I.A above, is intended to address uncertainties associated with inconclusive scientific and technical information, as well as to provide a reasonable degree of protection against hazards that research has not yet identified. The Administrator has taken the need to provide for an adequate margin of safety into account as an integral part of his decision-making on the appropriate standards in setting the standard at a level below the level where available epidemiologic studies, which include diverse populations that are broadly representative of the U.S. population including at-risk populations, have provided the strongest evidence supporting effects, and in other ways as well. For example, consideration of a margin of safety is reflected in the approach of setting the level of the annual standard near and somewhat below the 25th percentile PM
                        <E T="52">2.5</E>
                         concentrations from key U.S. epidemiologic studies (
                        <E T="03">i.e.,</E>
                         9.1 µg/m
                        <SU>3</SU>
                        ), as well as recognition that attaining a design value will generally result in significantly broader and greater improvements of air quality across an area (including but certainly not limited to areas near the design value monitor) (U.S. EPA, 2022a, sections 2.3.3.2.4 and 3.3.3.2.1, Table 3-5). Based on all of the considerations noted here, and considering the current body of evidence, including the associated limitations and uncertainties, in combination with the exposure/risk information, the Administrator concludes that a less stringent standard than the current standard would not provide the requisite protection of public health, including an adequate margin of safety.
                    </P>
                    <P>
                        Having concluded that a less stringent standard would not provide the requisite protection of public health, the Administrator next considers whether a more stringent standard would be appropriate. In so doing, he notes that a decision to set the level of the annual standard to below 9.0 µg/m
                        <SU>3</SU>
                         would place a large amount of the emphasis on potential public health importance of further reducing the occurrence of PM
                        <E T="52">2.5</E>
                         concentrations of concern, though the exposures about which he is most concerned are well controlled with an annual standard level of 9.0 µg/m
                        <SU>3</SU>
                        , as demonstrated by the quantitative risk assessment. Such a decision would also place greater weight on (1) further reducing ambient PM
                        <E T="52">2.5</E>
                         concentrations relative to those observed in long-and short-term epidemiologic studies, including those that he had judged to have significant uncertainties, including Canadian studies, studies using restricted analyses, and accountability studies; (2) shifting the air quality distribution in areas such that the highest exposure concentrations are reduced to below PM
                        <E T="52">2.5</E>
                         concentrations observed in epidemiologic studies to be in the 25th or lower percentile, for which the evidence is limited; and (3) further shifting exposure concentrations to those shown at the lower end of the distribution in the quantitative risk assessment, despite the important uncertainties in the overall risk assessment. As discussed in this section and in responses to significant comments above and in the Response to Comments document, the Administrator has concluded that placing a large emphasis on these factors and revising the standard to a level below 9.0 µg/m
                        <SU>3</SU>
                         would result in a standard that is more stringent than the evidence indicates to be sufficient to protect public health with an adequate margin of safety. Compared to a primary annual PM
                        <E T="52">2.5</E>
                         standard set at a level of 9.0 µg/m
                        <SU>3</SU>
                        , the Administrator concludes that the extent to which lower standard levels could result in further public health improvements becomes notably less certain.
                    </P>
                    <P>
                        Thus, having carefully considered the scientific evidence, quantitative information, CASAC advice, and public comments relevant to his decision on the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard, as discussed above and in the Response to Comments document, the Administrator is revising the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard to 9.0 µg/m
                        <SU>3</SU>
                        . In the Administrator's judgment, based on the currently available evidence and information, an annual standard set at this level and using the specified indicator, averaging time, and form, in conjunction with the other primary PM standards, would be requisite to protect public health with an adequate margin of safety. The Administrator judges that such a standard would protect, with an adequate margin of safety, the health of at-risk populations, including children, older adults, those with pre-existing cardiovascular and respiratory diseases, minority populations, and low SES populations. The Administrator believes that a standard set at 9.0 µg/m
                        <SU>3</SU>
                         would be sufficient to protect public health with a margin of safety, and believes that a lower standard would be more than what is necessary to provide this degree of protection. This judgment by the Administrator appropriately considers the degree of protection that is neither more nor less stringent than necessary for this purpose and recognizes that the CAA does not require that primary standards be set at a zero-risk level, but rather at a level that reduces risk sufficiently so as to protect public health with an adequate margin of safety.

                        In reaching his conclusions on adequacy of the current suite of primary PM
                        <E T="52">2.5</E>
                         standards, based on consideration of the available scientific evidence and quantitative information, the CASAC's advice and public comments, the Administrator finds that the available information is insufficient to call into question the adequacy of the public 
                        <PRTPAGE P="16286"/>
                        health protection afforded by the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. As described earlier in this section, the Administrator concludes that it is appropriate to retain the current indicator (PM
                        <E T="52">2.5</E>
                        ), averaging time (24-hour), and form (98th percentile, averaged over three years) for the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard and below explains the basis for his final decision that is also appropriate to retain the current level of the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard.

                    <P>
                        In reaching his conclusion to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard the Administrator does so in light of the conclusion that the epidemiologic evidence supports associations between short- and long-term PM
                        <E T="52">2.5</E>
                         exposures and adverse health effects, but that the epidemiologic evidence does not identify specific concentrations at which those effects occur and the Administrator has greatest confidence in effects where the bulk of the data is reported (
                        <E T="03">i.e.,</E>
                         the mean PM
                        <E T="52">2.5</E>
                         concentration, with some consideration for the 25th percentile of the air quality distribution). Thus, in considering the epidemiologic evidence, the Administrator concludes it is appropriate to focus on setting a generally controlling annual standard as the most effective and efficient way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures, and that it is appropriate to revise the level of the annual standard level to 9.0 µg/m
                        <SU>3</SU>
                        . In addition to the epidemiologic evidence, the Administrator also considers the available controlled human exposure studies, which provide evidence for health effects following single, short-term PM
                        <E T="52">2.5</E>
                         exposures to concentrations that typically correspond to upper end of the PM
                        <E T="52">2.5</E>
                         air quality distribution in the U.S. (
                        <E T="03">i.e.,</E>
                         “peak” concentrations). In so doing, the Administrator notes that these studies report statistically significant effects on one or more indicators of cardiovascular function following 2-hour exposures to PM
                        <E T="52">2.5</E>
                         concentrations at and above 120 μg/m
                        <SU>3</SU>
                         and at and above 149 μg/m
                        <SU>3</SU>
                         for vascular impairment, the effect shown to be most consistent across studies. In particular, the Administrator notes that a single study is assessed in the ISA Supplement that reports effects following 4-hour exposures at 37.8 µg/m
                        <SU>3</SU>
                        , although the results of this study are inconsistent with the results of the controlled human exposure studies assessed in the 2019 ISA. Along with the inconsistent results from the controlled human exposure studies, the Administrator also recognizes that effects observed in these studies are intermediate effects which are not typically considered adverse and that the study participants were healthy individuals. Taking into consideration the available scientific evidence, including the uncertainties and limitations, along with the CASAC's advice, the Administrator concludes that it is appropriate to maintain a primary 24-hour PM
                        <E T="52">2.5</E>
                         standard to protect against peak exposures.

                    <P>
                        Thus, the Administrator considers what primary 24-hour PM
                        <E T="52">2.5</E>
                         standard is requisite to provide supplemental protection against peak exposures. While having confidence that the revised annual standard will result in lowering risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposure by lowering the overall air quality distribution, as in the 2012 review, the Administrator recognizes that an annual standard alone would not be expected to offer sufficient protection with an adequate margin of safety against the effects of short-term PM
                        <E T="52">2.5</E>
                         exposures in all parts of the country. Therefore, he continues to conclude that it is appropriate to continue to provide supplemental protection by means of a 24-hour standard, in conjunction with a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>

                        In considering the available scientific evidence assessed in the 2019 ISA and ISA Supplement, the Administrator first considers the controlled human exposure studies for informing his decisions on the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, he notes that in their review of the 2021 draft PA, the majority of CASAC members expressed the view that controlled human exposure studies are not the best evidence to use for justifying retaining the 24-hour standard without revision, in part because these studies preferentially recruit less susceptible individuals and have a typical exposure duration much shorter than 24 hours. Thus, in the view of the majority, “the evidence of effects from controlled human exposure studies with exposures close to the current 24-hour standard supports epidemiological evidence for lowering the standard” (Sheppard, 2022a, p. 3-4 of consensus letter). In reviewing the controlled human exposure studies, the Administrator agrees with the majority of CASAC that these controlled human exposure studies generally do not include populations with substantially increased risk from exposure to PM
                        <E T="52">2.5</E>
                        , such as children, older adults, or those with more severe underlying illness. However, he disagrees with any conclusion that they should not be used to inform a decision about the adequacy of the current standard. The Administrator finds the information available from these studies to be useful, noting that the recently available controlled human exposure studies provide evidence for health effects following single, short-term exposures to PM
                        <E T="52">2.5</E>
                         concentrations that are greater than those allowed under the current standard. The results of the controlled human exposure studies are inconsistent, particularly at lower PM
                        <E T="52">2.5</E>
                         concentrations, but some studies do report statistically significant effects on one or more indicators of cardiovascular function following 2-hour exposures to PM
                        <E T="52">2.5</E>
                         concentrations at and above 120 μg/m
                        <SU>3</SU>
                         (and at and above 149 μg/m
                        <SU>3</SU>
                         for vascular impairment, the effect shown to be most consistent across studies). Additionally, one controlled human exposure study assessed in the ISA Supplement reports evidence of some effects for cardiovascular markers following 4-hour exposures to 37.8 µg/m
                        <SU>3</SU>
                         (Wyatt et al., 2020). However, there is inconsistent evidence for inflammation in other controlled human exposure studies evaluated in the 2019 ISA. The Administrator finds these studies are important in establishing biological plausibility for PM
                        <E T="52">2.5</E>
                         exposures causing more serious health effects, such as those seen in short-term exposure epidemiologic studies, and they provide support that more adverse effects may be experienced following longer exposure durations and/or exposure to higher concentrations. As described in more detail in responding to public comments in section II.B.3 above, he notes that although the controlled human exposure studies do not provide a threshold below which no effects occur, the observed effects in these controlled human exposures studies are ones that signal an intermediate effect in the body, likely due to short-term exposure to PM
                        <E T="52">2.5</E>
                        , and typically would not, by themselves, be judged as adverse. As noted in sections II.A.2 and II.B.3 above, associated judgments regarding adversity or health significance of measurable physiological responses to air pollutants in previous NAAQS reviews have been informed by guidance, criteria or interpretative statements developed within the public health community. This type of information on adversity of effects is particularly informative to the Administrator's judgments regarding the adversity of the effects observed in the controlled human exposure studies which are short-term in nature (
                        <E T="03">i.e.,</E>
                         generally ranging from 2- to 5-hours), including those studies that are

                        conducted at near-ambient PM
                        <E T="52">2.5</E>
                         concentrations. Based on the observation that the effects observed in Wyatt et al. (2020) are not by themselves adverse, and the fact that the findings of this study are inconsistent with other currently available evidence regarding the level at which effects are observed, the Administrator disagrees with the view expressed by the majority of CASAC that this study supports epidemiologic evidence for lowering the 24-hour standard.

                        Consistent with his approach in reaching his proposed decision and taking into consideration these points as well as balancing these limitations (

                         that the health outcomes observed in these controlled human exposure studies are not clearly adverse and that the studies generally do not include those at increased risk from PM

                         exposure), the Administrator still considers it appropriate to ensure that the 24-hour PM

                         standard provides protection against health effects consistently observed in the controlled human exposure studies. He next examines the air quality analyses, described in more detail in section II.A.c.i above, to assess whether during recent air quality conditions, areas meeting the current standards would experience PM
                        <E T="52">2.5</E>
                         concentrations reported in these controlled human exposure studies. He observes that air quality analyses demonstrate that the PM
                        <E T="52">2.5</E>
                         exposures shown to cause consistent effects in the controlled human exposure studies are well above the ambient concentrations typically measured in locations meeting the current primary standards, and therefore suggest that the current primary PM
                        <E T="52">2.5</E>
                         standards provide protection against these “peak” concentrations. In fact, at air quality monitoring sites meeting the current primary PM
                        <E T="52">2.5</E>
                         standards (

                        . Though two-hour concentrations are higher at monitoring sites violating the current standards, they generally remain below 16 μg/m

                        <FTREF/>
                         that provide a more refined analysis of whether areas that meet the current standards experience peak concentrations reported in controlled human exposure studies. He notes that 2-hour observations greater than 120 μg/m
                        <SU>3</SU>
                         and 4-hour observations greater than 38 μg/m

                         in ambient air far below the exposure concentrations in controlled human exposure studies where consistent effects have been observed, and notes that while these studies generally do not include the most at-risk individuals, the exposure concentrations in these studies also do not elicit adverse effects.

                        Further, in light of the Administrator's emphasis on the annual standard as the controlling standard, with the 24-hour standard providing supplemental protection against peak concentrations, he next considers the potential impact of a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                         on the occurrence of peak sub-daily PM

                        <FTREF/>
                         where he observes that lower percentages of concentrations greater than 120 µg/m
                        <SU>3</SU>
                         and 38 µg/m
                        <SU>3</SU>
                         occur in areas meeting an annual standard of 9.0 µg/m
                        <SU>3</SU>
                         and a 24-hour standard of 35 µg/m
                        <SU>3</SU>
                        , versus an annual standard of 12.0 µg/m
                        <SU>3</SU>
                         and a 24-hour standard of 35 µg/m
                        <SU>3</SU>
                        . Thus, he concludes that an annual standard that is controlling across most areas of the country will continue to effectively limit peak daily concentrations in conjunction with the existing 24-hour standard, with its level of 35 µg/m
                        <SU>3</SU>
                         and 98th percentile form, which continues to provide supplemental protection against peak concentrations.

                        In addition, the Administrator also notes that the majority of the CASAC in their review of the 2021 draft PA, as well as a number of public commenters, support their recommendation to revise the current 24-hour standard by pointing to “substantial epidemiologic evidence from both morbidity and mortality studies” which “includes three U.S. air pollution studies with analyses restricted to 24-hour concentrations below 25 μg/m
                        <SU>3</SU>
                        ” (Sheppard, 2022a, p. 17 consensus responses). The Administrator notes that the epidemiologic evidence available in this reconsideration, including the studies that restrict short-term PM
                        <E T="52">2.5</E>
                         exposures (

                        <SU>3</SU>
                        , provides support for positive and statistically significant associations between short-term exposure to PM
                        <E T="52">2.5</E>
                         and all-cause mortality (Di et al., 2017a) and CVD hospital admissions (deSouza et al., 2021; Di et al., 2017a). He agrees that these studies help to provide additional support for reaching conclusions on causality in the 2019 ISA. He further agrees that the available epidemiologic studies provide important information that it is appropriate to consider in this reconsideration, including information on associations between health effects and PM
                        <E T="52">2.5</E>
                         exposures in diverse populations that are broadly representative of the U.S. population, and include populations identified as at-risk (

                         older adults, minority populations), as well as evidence of linear, no-threshold concentration-response relationships in those associations, although with less certainty in the shape of the curve at long-term average concentrations below about 8 μg/m

                        However, the Administrator also notes significant limitations in the currently available epidemiologic information that limit his ability to draw conclusions from the key short-term studies, including those that employ restricted analyses, to inform his decision regarding the level of the 24-hour PM
                        <E T="52">2.5</E>
                         standard. As a result of these limitations, the Administrator does not find that the short-term epidemiologic studies, or the other evidence such as the controlled human exposure studies or the risk assessment, provide a sufficient justification for revising the 24-hour standard.
                    </P>
                    <P>
                        First, he notes that short-term epidemiologic studies examine associations between day-to-day variations in PM
                        <E T="52">2.5</E>
                         concentrations and health outcomes, often over multi-year study periods. As such, these studies report long-term mean 24-hour PM
                        <E T="52">2.5</E>
                         concentrations (
                        <E T="03">e.g.,</E>
                         mean 24-hour PM
                        <E T="52">2.5</E>
                         concentrations over multi-year study periods), rather than at specific points in the distribution (
                        <E T="03">i.e.,</E>
                         90th or 98th percentile 24-hour concentrations) at which effects occur. Further, he notes 
                        <PRTPAGE P="16288"/>
                        that while there can be considerable variability in daily exposures over a multi-year study period, the bulk of the observations reflect days with ambient PM
                        <E T="52">2.5</E>
                         concentrations in the middle of the air quality distribution (
                        <E T="03">i.e.,</E>
                         “typical” days rather than days with extremely low or extremely high concentrations). As a result, the results of these studies are more directly applicable to decisions regarding the annual standard (which is based on the long-term mean of both short- and long-term epidemiologic studies), and the fact that they do not report other air quality statistics, such as the 98th percentile concentrations which might be more directly compared to the level of the 24-hour standard, makes them less useful for informing decisions on the 24-hour standard. As discussed in responding to comments above, the form of the annual standard is based on the annual mean PM
                        <E T="52">2.5</E>
                         concentration averaged over three years,
                        <SU>123</SU>
                        <FTREF/>
                         which makes it better suited as a basis for controlling air quality to avoid effects observed in both long-term and short-term epidemiologic studies. By contrast, the form of the 24-hour standard is the 98th percentile averaged over three years, which makes it appropriate for controlling short-term peak concentrations. However, based on the available air quality information, including distribution statistics of PM
                        <E T="52">2.5</E>
                         concentrations and health events reported in the short-term epidemiologic studies, these studies are too limited in their ability to identify health effects attributable to specific short-term peak concentrations that are necessary to evaluate whether the 24-hour standard with its 98th percentile form should be revised (
                        <E T="03">e.g.,</E>
                         restricted epidemiologic studies do not report the number or the percentile of health events or the percentile of PM
                        <E T="52">2.5</E>
                         concentrations across the highest part of the restricted air quality distribution, including the 98th percentile). Thus, the Administrator does not consider it appropriate to use the reported means from short-term studies to determine the appropriate level for a 24-hour standard with a 98th percentile form.

                        Similarly, the Administrator does not consider the results of the restricted analyses to be well suited to informing the choice of level for a 24-hour standard. Restricted analyses use a subset of data from their main analyses to evaluate health events that occur at concentrations below a certain concentration (

                         25 μg/m
                        <SU>3</SU>
                        ). The Administrator notes that the associations between the health effects (
                        <E T="03">e.g.,</E>
                         mortality and cardiovascular morbidity) and PM
                        <E T="52">2.5</E>
                         concentrations remain even after excluding higher concentrations in the restricted analyses, and he also recognizes that the magnitude of the effect is generally greater in the restricted analyses compared to the associations reported in the main analysis. He considers such analyses to be informative in indicating that the health effects association reported in the main (unrestricted) analysis are not driven only by the upper peaks of the PM
                        <E T="52">2.5</E>
                         air quality distribution, but rather persist at lower portions of the distribution (consistent with his emphasis on the annual standard, which is focused on exposures near the mean concentration, where the bulk of the exposure distribution is concentrated). Indeed, he notes that if peak concentrations were the principal driver of health effects associated with PM
                        <E T="52">2.5</E>
                         exposure, one might expect the associations to become weaker as the upper portion of the data is excluded in the restricted analyses, which is not what is reported by the analyses (
                        <E T="03">e.g.,</E>
                         the restricted analyses generally report associations that are greater in magnitude compared to the main analyses). However, he disagrees with the assertion by the CASAC in their review of the 2021 draft PA and some public commenters that it would be appropriate to focus on the specific PM
                        <E T="52">2.5</E>
                         concentration (
                        <E T="03">e.g.,</E>
                         25 or 30 μg/m

                        ) at which the analysis was restricted as the basis for choosing a 24-hour standard level. The Administrator recognizes that in restricted analyses, while an association continues to persist across the full range of the air quality distribution, and that the cutpoint concentration at which the analysis was restricted (
                        <E T="03">e.g.,</E>
                         25 or 30 µg/m
                        <SU>3</SU>
                        ) becomes the maximum PM
                        <E T="52">2.5</E>
                         concentration in the distribution, he also notes that these studies do not provide information related to the distribution of health events and PM
                        <E T="52">2.5</E>
                         concentrations, and as such, he is more uncertain where the bulk of the data are and where he has confidence in the reported association.
                        <SU>124</SU>
                        <FTREF/>
                         He notes that no evidence exists to support a conclusion that the PM
                        <E T="52">2.5</E>
                         concentration chosen as the cutpoint in a restricted analysis has any bearing on the concentration at which effects are likely to occur (or not occur). He notes that, as with long-term studies, the evidence does not suggest there is a specific point in the air quality distribution of these short-term studies that represents a “bright line” at and above which effects have been observed and below which effects have not been observed. In order to identify a level of the 24-hour standard based on associations between the “upper end” of exposures, either in the unrestricted or the restricted analyses, and adverse health effects, it would be necessary to have a better understanding of how specific 24-hour concentrations correspond to the frequency and total number of observed health events in the study. Currently, such information, including 98th percentile statistics, are not reported in the key short-term epidemiologic studies (and if they were reported, the Administrator would have to carefully consider how to weigh the data). As such, in reaching his decision on the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator judges that the currently available information from short-term epidemiologic studies, including those that employ restricted analyses, does not provide a sufficient basis to revise the current 24-hour standard, given that the 24-hour standard focuses on reducing “peak” exposures (with its 98th percentile form), but rather that such information supports his judgment that it is appropriate to focus on revising the annual standard for purposes of reducing all exposures, across the entire distribution of air quality, to increase public health protection.

                         standard, the Administrator continues to view an approach that focuses on setting a generally controlling annual standard as the most effective and efficient way to reduce total population risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures. Additionally, he emphasizes that improvements in air quality associated with meeting an annual standard level of 9.0 µg/m
                        <SU>3</SU>
                         will result in lowering risk associated with both long- and short-term PM
                        <E T="52">2.5</E>
                         exposure by lowering the overall air quality distribution. The Administrator concludes that reducing the annual standard is the most efficient way to reduce the risks from short-term exposures identified in the epidemiologic studies, as the available evidence suggests the bulk of the risk comes from the large number of days across the bulk of the air quality distribution, not the relatively small number of days with peak concentrations. However, as in the 2012 
                        <PRTPAGE P="16289"/>
                        review, the Administrator recognizes that an annual standard alone would not be expected to offer sufficient protection with an adequate margin of safety against the effects of short-term PM
                        <E T="52">2.5</E>
                         exposures in all parts of the country and concludes that, in conjunction with a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                        , it is appropriate to continue to provide supplemental protection by means of a 24-hour standard, particularly for areas with high peak-to-mean ratios possibly associated with strong local or seasonal sources.

                    <P>
                        In selecting the level of a 24-hour standard designed to provide supplemental protection against peak exposures (in conjunction with a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                        ), the Administrator considers the information from the controlled human exposure studies and the EPA's analysis of peak concentrations observed in areas meeting the current standard of 35 µg/m
                        <SU>3</SU>
                         in conjunction with a revised standard of 9.0 µg/m
                        <SU>3</SU>
                         to be of particular relevance. He notes the controlled human exposure evidence includes studies reporting effects on one or more indicators of cardiovascular function following 2-hour exposures at and above 120 µg/m
                        <SU>3</SU>
                        , including effects reported at and above 149 µg/m
                        <SU>3</SU>
                         for vascular impairment, the effect shown to be most consistent across studies, and less consistent effects at lower concentrations, including a single study at near ambient concentrations (Wyatt et al., 2020) reporting effects following 4-hour exposures at 37.8 µg/m
                        <SU>3</SU>
                        . He recognizes that the effects observed (in those studies that observed effects) are ones that signal an intermediate effect in the body, likely due to short-term exposure to PM
                        <E T="52">2.5</E>
                        , and typically would not, by themselves, be judged as adverse, and the study participants were healthy individuals.

                    <P>
                        He notes in particular that, in the EPA's analysis, in areas meeting the current 24-hour standard and the revised annual standard 0.029 percent of 2-hour observations and 0.41 percent of 4-hour observations reach PM
                        <E T="52">2.5</E>
                         concentrations higher than 120 µg/m
                        <SU>3</SU>
                         and 37.8 µg/m
                        <SU>3</SU>
                        , respectively. He also notes the lack of evidence of effects from controlled human exposure studies at levels below the current 24-hour standard and the fact that the results of Wyatt et al. (2020) are inconsistent with other available studies, as well as the intermediate nature of effects observed in this study. In his judgment, the small number of occurrences of peak exposures indicate that, in conjunction with a revised annual standard of 9.0 µg/m
                        <SU>3</SU>
                        , the current 24-hour standard of 35 µg/m
                        <SU>3</SU>
                         remains requisite to protect public health with an adequate margin of safety, and that there is substantial basis to doubt whether further improvements in public health would be achieved by further reducing these exposures. Furthermore, the Administrator concludes that due to the limitations and uncertainties outlined above, the information from recent short-term epidemiologic studies, including those that use restricted analyses, is inadequate to inform decisions regarding the adequacy of the current 24-hour standard. Thus, in reaching his decision on the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator concludes that currently available evidence does not call into question the adequacy of the current standard.

                    <P>
                        In addition to the scientific evidence, the Administrator also considers the risk assessment in evaluating the appropriate level of the 24-hour PM
                        <E T="52">2.5</E>
                         standard. The risk assessment indicates that the annual standard is the controlling standard across most of the urban study areas evaluated (
                        <E T="03">i.e.,</E>
                         when air quality related to the annual average PM
                        <E T="52">2.5</E>

                        <E T="52">2.5</E>
                         concentrations are also expected to decrease). When air quality is adjusted to just meet an alternative 24-hour standard level of 30 μg/m
                        <SU>3</SU>
                         in the areas where the 24-hour standard is controlling, the risk assessment estimates reductions in PM
                        <E T="52">2.5</E>
                        -associated risks across a more limited population and number of areas compared to when air quality is adjusted to simulate alternative levels for the annual standard (
                        <E T="03">i.e.,</E>
                         where the annual standard is controlling), and these predictions are largely confined to areas located in the western U.S., several of which are also likely to experience risk reductions upon meeting a revised annual standard. With respect to the CASAC's advice in their review of the 2021 draft PA, the Administrator notes that the minority of CASAC advised that these results suggest that the annual standard can be used to limit both long- and short-term PM
                        <E T="52">2.5</E>
                         concentrations and views these risk assessment results as supporting the conclusion that the current 24-hour standard is adequate (Sheppard, 2022a, p. 4 of consensus letter). In contrast, the majority of CASAC members in their review of the 2021 draft PA, as well as a number of public commenters that support revision of the 24-hour standard, placed greater weight on the evidence-based considerations (
                        <E T="03">e.g.</E>
                         scientific evidence, like the restricted analyses) than on the values estimated by the risk assessment, noting the potential for uncertainties in how the risk assessment was able to “capture areas with wintertime stagnation and residential wood-burning where the annual standard is less likely to be protective” (Sheppard, 2022a, p. 4 of consensus letter).

                        In considering the application of the risk assessment to judgments about the adequacy of the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator again notes that the risk assessment analyses of PM
                        <E T="52">2.5</E>
                        -attributable mortality use input data that include C-R functions from epidemiologic studies that have no threshold and a linear C-R relationship down to zero, as well an air quality adjustment approach that incorporates proportional decreases in PM
                        <E T="52">2.5</E>
                         concentrations to meet lower standard levels. As such, the Administrator notes that this quantitative approach does not incorporate any elements of uncertainty in associations of health effects at lower concentrations and that simulated air quality improvements will always lead to proportional decreases in risk (
                        <E T="03">i.e.,</E>
                         each additional µg/m
                        <SU>3</SU>
                         reduction produces additional benefits with no clear stopping point at any PM
                        <E T="52">2.5</E>
                         concentration). Therefore, the Administrator recognizes that while the risk estimates can help to place the evidence for specific health effects into a broader public health context, the results should be considered along with the inherent uncertainties and limitations of such analyses when informing judgments about the potential for additional public health protection associated with PM
                        <E T="52">2.5</E>
                         exposure and related health effects. Further, the Administrator notes additionally that air quality analyses have also been considered in looking at the adequacy of the 24-hour standard in controlling peak PM
                        <E T="52">2.5</E>
                         concentrations of potential concern,

                         and that those analyses included monitoring information from across the entire U.S., specifically highlighting areas with higher peak concentrations and including areas impacted by wintertime stagnation and residential wood-burning. Thus, while the risk assessment may have focused on a subset of areas across the U.S. based on the study area selection criteria, the Administrator is considering a broader set of information in reaching his conclusions regarding the appropriateness of the current 24-

                        The Administrator also considers the advice from the CASAC in their reviews of the 2019 draft PA and 2021 draft PA. In their review of the 2019 draft PA, the CASAC “agrees with the EPA and finds that the available evidence does not call into question the adequacy of public health protection afforded by the current 24-hour PM
                        <E T="52">2.5</E>
                         standard and concurs that it be retained” (Cox, 2019b, p. 3 of letter). He also notes that in their review of the 2021 draft PA, the CASAC did not reach consensus on whether the current 24-hour standard is adequate, with the majority of the CASAC recommending that the 24-hour standard be revised and the minority of the CASAC recommending that the standard be retained. The majority of the CASAC members further stated that “[t]here is also less confidence that the annual standard could adequately protect against health effects of short-term exposures. A range of 25-30 μg/m
                        <SU>3</SU>

                        <E T="52">2.5</E>
                         standard would be adequately protective” (Sheppard, 2022a, p. 4 of consensus letter). The Administrator also acknowledges that some public commenters agreed with the majority of the CASAC in supporting a revision to the level of the 24-hour standard to a range between 25-30 µg/m
                        <SU>3</SU>
                        . These commenters cite a number of reasons, including: (1) Results from controlled human exposure studies at near ambient concentrations; (2) aspects of the scientific evidence, including restricted analyses that report positive and significant associations below 35 µg/m
                        <SU>3</SU>
                        ; and (3) quantitative risk analyses that show decreasing risk with decreasing PM
                        <E T="52">2.5</E>
                         concentrations. In responding to these comments, the Administrator recognizes that some commenters have different interpretations of the evidence, air quality information, and quantitative results from the risk assessment in this review and would make different judgments about the weight to place on the relative strength and limitations of the currently available scientific evidence and information and how such information could be used in making public health policy decisions on the 24-hour standard. However, as outlined above, the Administrator has carefully considered the information available from controlled human exposure studies and short-term epidemiologic studies, and weighed the strengths and limitations of this evidence in formulating his decisions. Furthermore, as discussed above the Administrator has noted significant uncertainties and limitations inherent in the risk estimates, as well as noting that very few areas were included. In addition, he has given careful consideration to the majority of the CASAC's advice in their review of the 2021 draft PA, but has drawn different conclusions with respect to how currently available evidence and air quality information inform the selection of level for the 24-hour primary PM

                        <SU>3</SU>
                         would place a large amount of emphasis on the potential public health importance of further reducing the occurrence of peak PM
                        <E T="52">2.5</E>
                         concentrations. However, the Administrator concludes that there is insufficient basis to conclude that a more stringent standard to further reduce peak concentrations is needed or would benefit public health. As discussed above, he judges that the PM
                        <E T="52">2.5</E>
                         exposures in controlled human exposure studies that correspond to peak concentrations will already be well controlled via the combination of the revised annual standard, with a level of 9.0 µg/m
                        <SU>3</SU>
                        , and the 24-hour standard with its level 35 µg/m
                        <SU>3</SU>
                         and its 98th percentile form. Taking into consideration the inconsistent results reported in controlled human exposure studies, the intermediate nature of the health effects observed in the controlled human exposure studies that are not typically considered adverse, the health status of the study participants, and how infrequently peak concentrations of potential concern are anticipated to occur in areas meeting the revised primary annual PM
                        <E T="52">2.5</E>
                         standard, he judges that the current 24-hour standard is requisite to protect against the effects reported in these studies with an adequate margin of safety. Likewise, he judges that neither the epidemiologic studies (including the studies that use restricted analyses) nor the risk assessment provide a sufficient basis for revising the 24-hour standard. As discussed above, the epidemiologic studies, including short-term studies and those with restricted analyses, are not well-suited for identifying a level for a 24-hour standard to address health effects associated with peak concentrations. The restricted analyses support the conclusion that the health effects associated with PM
                        <E T="52">2.5</E>
                         is not associated primarily with exposure to higher concentrations of the main analyses, but like other epidemiologic studies they typically report only long-term mean 24-hour concentrations (
                        <E T="03">e.g.,</E>
                         restricted epidemiologic studies do not report the number or the percentile of health events or the percentile of PM
                        <E T="52">2.5</E>
                         concentrations across the highest part of the restricted air quality distribution, including the 98th percentile) and do not identify any particular concentration within the air quality distribution above which effects have been observed and below which effects have not been observed. Similarly, the risk assessment highlights that the annual standard is controlling across much of the U.S. and is generally more effective at reducing risk than the 24-hour standard and, taking into account the limitations and assumptions of the risk assessment discussed above, does not provide a basis for revising the 24-hour standard. For the reasons discussed herein, the Administrator judges that the uncertainties as to whether there would be public health benefits from a more stringent 24-hour standard are too great to justify revising the standard.
                    </P>
                    <P>
                        Thus, having carefully considered the scientific evidence, quantitative information, CASAC advice, and public comments, the Administrator is retaining the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard, with its level of to 35 µg/m
                        <SU>3</SU>
                         and its 98th percentile form. In the Administrator's judgment, based on the currently available evidence and information, a 24-hour standard set at this level and using the specified indicator, averaging time, and form would be requisite to protect public health with an adequate margin of safety, in conjunction with the annual standard. As noted, in evaluating the adequacy of the current standards, the Administrator focuses on evaluating the public health protection afforded by the annual and 24-hour standards, taken together, against adverse health effects associated with long- or short-term PM
                        <E T="52">2.5</E>
                         exposures. A 24-hour standard set at a level of 35 µg/m
                        <SU>3</SU>
                        , in conjunction with a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                        , in the judgment of the Administrator, provides an appropriate level of public health protection, for both long- and short-term PM
                        <E T="52">2.5</E>
                         exposures. The Administrator believes that a 24-hour standard set at 35 µg/m
                        <SU>3</SU>
                         would continue to be sufficient to protect public health with a margin of safety, and believes that a lower standard would be more than what is necessary to provide this degree of protection when considered in conjunction with a revised annual standard. The Administrator concludes the current 24-hour standard at a level of 35 µg/m
                        <SU>3</SU>
                        , in conjunction with a revised annual standard level of 9.0 µg/m
                        <SU>3</SU>
                        , will provide appropriate protection 
                        <PRTPAGE P="16291"/>
                        in areas in which the long-term mean concentrations are already relatively low (
                        <E T="03">i.e.,</E>
                         below 9 µg/m
                        <SU>3</SU>
                        ) but where there may be elevated short-term peak PM
                        <E T="52">2.5</E>
                         concentrations, often associated with strong local or seasonal sources. This judgment by the Administrator appropriately considers the degree of protection that is neither more nor less stringent than necessary for this purpose and recognizes that the CAA does not require that primary standards be set at a zero-risk level, but rather at a level that reduces risk sufficiently so as to protect public health with an adequate margin of safety.

                        , given all of the evidence and information discussed above, the Administrator judges that the revised suite of primary PM
                        <E T="52">2.5</E>
                         standards and the rationale supporting these levels appropriately reflects consideration of the strength of the available evidence and other information and its associated uncertainties as well as the advice of CASAC and consideration of public comments. He additionally judges that this suite of primary PM

                         standards is requisite to protect public health, including at-risk populations, with an adequate margin of safety from effects associated with long and short-term exposures to fine particles. This judgment by the Administrator appropriately considers the requirement for standards that are requisite to protect public health but are neither more nor less stringent than necessary.

As described in section I above and in section 1.2 of the ISA Supplement, the scope of the updated scientific evaluation of the health effects evidence is based on those PM size fractions, exposure durations, and health effects category combinations where the 2019 ISA concluded a causal relationship exists (U.S. EPA, 2019a, U.S. EPA, 2022b).). Therefore, because the 2019 ISA did not conclude a causal relationship for PM

                         for any exposure durations or health effect categories, the ISA Supplement does not include an evaluation of additional studies for PM

                        Consistent with the 2009 ISA, the 2019 ISA concluded that the available epidemiologic, controlled human exposure, and animal toxicological studies, including uncertainties, provided support for the causality determinations of “suggestive of, but not sufficient to infer, a causal relationship” between short-term exposures to PM
                        <E T="52">10-2.5</E>
                         and cardiovascular effects, respiratory effects, and mortality (U.S. EPA, 2019a, section 1.4.2). The 2019 ISA also reached the conclusion that the evidence supports a “suggestive of, but not sufficient to infer, a causal relationship” between short-term PM

                        Compared to the 2009 ISA, the 2019 ISA includes expanded evidence for the relationships between long-term exposures and cardiovascular effects, metabolic effects, nervous system effects, cancer, and mortality. The 2019 ISA concluded that the small number of epidemiologic and experimental studies, including uncertainties, contribute to the determination that, “the evidence is suggestive of, but not sufficient to infer, a causal relationship between long-term PM

This determination is also the first for long-term exposures and metabolic effects, as the 2009 ISA did not include metabolic effects as an endpoint (U.S. EPA, 2019a section 1.4.2).

                         and mortality that were statistically significant and remained so in copollutant models (U.S. EPA, 2019a). In addition to the epidemiologic studies, there were a small number of controlled human exposure studies evaluated in the 2019 ISA that reported alterations in heart rate variability or increased pulmonary inflammation following short-term exposure to PM

                        -related health effects, the then-Administrator noted that epidemiologic studies continued to report positive associations with mortality and morbidity in cities across North America, Europe, and Asia, where PM
                        <E T="52">10-2.5</E>
                         sources and composition were expected to vary widely. While significant uncertainties remained in the 2020 review, the then-Administrator recognized that this expanded body of evidence had broadened the range of effects that have been linked with PM
                        <E T="52">10-2.5</E>
                         exposures. The studies evaluated in the 2019 ISA expanded the scientific foundation presented in the 2009 ISA and led to revised causality determinations (and new determinations) for long-term PM

                        exposures and mortality, cardiovascular effects, metabolic effects, nervous system effects, and cancer (85 FR 82726, December 18, 2020). Drawing from his consideration of this evidence, the then-Administrator concluded that the scientific information available since the time of the last review supported a decision to maintain a primary PM
                        <E T="52">10</E>
                         standard to provide public health protection against PM

                         exposures, regardless of location, source of origin, or particle composition (85 FR 82726, December 18, 2020). With regard to uncertainties in the available evidence, the then-Administrator first noted that a number of limitations were identified in the 2012 review related to: (1) Estimates of ambient PM
                        <E T="52">10-2.5</E>
                         concentrations used in epidemiologic studies; (2) limited evaluation of copollutant models to address the potential for confounding; and (3) limited experimental studies supporting biological plausibility for PM
                        <E T="52">10-2.5</E>
                        -related effects. Despite the expanded body of evidence for PM
                        <E T="52">10-2.5</E>
                         exposures and health effects, the then-Administrator recognized that uncertainties in the 2020 review continued to include those associated with the exposure estimates used in epidemiologic studies, the independence of the PM
                        <E T="52">10-2.5</E>
                         health effect associations, and the biologically plausible pathways for PM
                        <E T="52">10-2.5</E>
                         health effects (85 FR 82726, December 18, 2020). These uncertainties contributed to the 2019 ISA determinations that the evidence is at most “suggestive of, but not sufficient to infer” causal relationships (85 FR 82726, December 18, 2020). In considering the available evidence in his basis for the decision, the then-Administrator emphasized evidence supporting “causal” and “likely to be causal” relationships, and therefore, judged that the PM
                        <E T="52">10-2.5</E>
                        -related health effects evidence provided an uncertain scientific foundation for making standard-setting decisions. He further judged limitations in the evidence raised questions as to whether additional public health improvements would be achieved by revising the existing PM
                        <E T="52">10</E>
                         standard (85 FR 24126, April 30, 2020). In the 2020 decision, for all of the reasons discussed above and recognizing the CASAC conclusion that the evidence provided support for retaining the current standard, the then-Administrator concluded that it was appropriate to retain the existing primary PM
                        <E T="52">10</E>
                         standard, without revision. His decision was consistent with the CASAC advice related to the primary PM
                        <E T="52">10</E>
                         standard. Specifically, the CASAC agreed with the 2020 PA conclusions that, while these effects are important, the “evidence does not call into question the adequacy of the public health protection afforded by the current primary PM
                        <E T="52">10</E>
                         standard” and “supports consideration of retaining the current standard in this review” (Cox, 2019b, p. 3 of consensus letter). Thus, the then-Administrator concluded that the primary PM
                        <E T="52">10</E>
                         standard (in all of its elements (

                         has been strengthened for some health effect categories since the completion of the 2009 ISA, the 2019 ISA concludes that overall “the uncertainties in the evidence identified in the 2009 ISA have, to date, still not been addressed” (U.S. EPA, 2019a, section 1.4.2, p. 1-41; U.S. EPA, 2022b, section 4.3.1).

                         concentrations have not been systematically evaluated (U.S. EPA, 2019a, section 3.3.1.1), contributing to uncertainty regarding the spatial and temporal correlations in PM

                         concentrations across methods and in the PM

As reported in the 2019 ISA, some cohort studies conducted in the U.S. and Europe report positive associations between long-term PM

As discussed above, temporal and spatial correlations between these approaches have not been evaluated, contributing to uncertainty regarding the potential for exposure measurement error (U.S. EPA, 2019a, section 3.3.1.1 and Table 11-11). The 2019 ISA concludes that this uncertainty “reduces the confidence in the associations observed across studies” (U.S. EPA, 2019a, p. 11-125). The 2019 ISA additionally concludes that the evidence for long-term PM
                        <E T="52">10-2.5</E>
                         exposures and cardiovascular effects, respiratory morbidity, and metabolic disease provide limited biological plausibility for PM

The 2019 ISA concludes that, overall, the assessment of potential copollutant confounding is limited due to the lack of information on the correlation between PM

The evidence for associations with cardiovascular morbidity has grown and, while results across studies are not entirely consistent, some epidemiologic studies report positive associations with ischemic heart disease (IHD) and MI (U.S. EPA, 2019a, Figure 6-34); stroke (U.S. EPA, 2019a, Figure 6-35); atherosclerosis (U.S. EPA, 2019a, section 6.4.5); venous thromboembolism (VTE) (U.S. EPA, 2019a, section 6.4.7); and blood pressure and hypertension (U.S. EPA, 2019a, Section 6.4.6).

                         exposure and cardiovascular effects was “suggestive of a causal relationship.” This conclusion was based on several epidemiologic studies reporting associations between short-term PM

In addition, dust storm events resulting in high concentrations of crustal material were linked to increases in total cardiovascular disease emergency department visits and hospital admissions. However, the 2009 ISA noted the potential for exposure measurement error primarily due to the different methods used across studies to estimate PM

                         concentrations in epidemiologic studies compare amongst one another and subsequently how exposure measurement error varies between each method. Specifically, it is unclear how well-correlated PM

                         concentrations are both temporally and spatially across these methods and therefore whether exposure measurement error varies across these methods.

                         exposure to asthma exacerbation and respiratory mortality, with some evidence that associations remain positive (though attenuated in some studies of mortality) in copollutant models that include PM
                        <E T="52">2.5</E>
                         or gaseous pollutants. Epidemiologic studies provide limited evidence for positive associations with other respiratory outcomes, including COPD exacerbation, respiratory infection, and combined respiratory-related diseases (U.S. EPA, 2019a, Table 5-36). As noted above for other endpoints, an uncertainty in these epidemiologic studies is the lack of a systematic evaluation of the various methods used to estimate PM
                        <E T="52">10-2.5</E>
                         concentrations and the resulting uncertainty in the spatial and temporal variability in PM
                        <E T="52">10-2.5</E>
                         concentrations compared to PM
                        <E T="52">2.5</E>
                         (U.S. EPA, 2019a, sections 2.5.1.2.3 and 3.3.1.1). Specifically, the existing monitoring networks do not provide a good characterization of how well correlated concentrations are both spatially and temporally across the PM
                        <E T="52">10-2.5</E>
                         estimation methods and overall spatial and temporal patterns in PM

                         concentrations. Taken together, the 2019 ISA concludes that “the collective evidence is suggestive of, but not sufficient to infer, a causal relationship between short-term PM
                        <E T="52">10-2.5</E>
                         exposure and respiratory effects” (U.S. EPA, 2019a, p. 5-270).

                        In the 2012 review, little information was available from studies of cancer following inhalation exposures to PM
                        <E T="52">10-2.5</E>
                        . Thus, the 2009 ISA determined the evidence was “inadequate to evaluate the relationship between long-term PM
                        <E T="52">10-2.5</E>
                         exposures and cancer” (U.S. EPA, 2009a). The scientific information evaluated in the 2019 ISA of long-term PM
                        <E T="52">10-2.5</E>
                         exposure and cancer remains limited, with a few recent epidemiologic studies reporting positive, but imprecise, associations with lung cancer incidence (U.S. EPA, 2019a). Moreover, uncertainty remains in these studies with respect to exposure measurement error due to the use of PM
                        <E T="52">10-2.5</E>
                         predictions that have not been validated by monitored PM

                         concentrations (U.S. EPA, 2019a, sections 3.3.2.3 and 10.3.4). Relatively few experimental studies of PM
                        <E T="52">10-2.5</E>
                         have been conducted, though available studies indicate that PM

                         exhibits two key characteristics of carcinogens: genotoxicity and oxidative stress. While limited, such experimental studies provide some evidence of biological plausibility for the findings in a small number of epidemiologic studies (U.S. EPA, 2019a, section 10.3.4).

                        Taken together, the small number of epidemiologic and experimental studies, along with uncertainty with respect to exposure measurement error, contribute to the determination in the 2019 ISA that, “the evidence is suggestive of, but not sufficient to infer, a causal relationship between long-term PM
                        <E T="52">10-2.5</E>

                        -related metabolic effects. One epidemiologic study in the 2019 ISA reports an association between long-term PM
                        <E T="52">10-2.5</E>
                         exposure and incident diabetes, while additional cross-sectional studies report associations with effects on glucose or insulin homeostasis (U.S. EPA, 2019a, section 7.4). As discussed above for other outcomes, uncertainties with the epidemiologic evidence include the potential for copollutant confounding and exposure measurement error due to the different methods used across studies to estimate PM
                        <E T="52">10-2.5</E>
                         concentrations (U.S. EPA, 2019a, Tables 7-14 and 7-15). The evidence base to support the biological plausibility of metabolic effects following PM
                        <E T="52">10-2.5</E>
                         exposures is limited, but a cross-sectional study that investigated biomarkers of insulin resistance and systemic and peripheral inflammation may support a pathway leading to type 2 diabetes (U.S. EPA, 2019a, sections 7.4.1 and 7.4.3). Based on the expanded, though still limited evidence base, the 2019 ISA concludes that, “[o]verall, the evidence is suggestive of, but not sufficient to infer, a causal relationship between [long]-term PM

                         and impaired cognition and anxiety in adults in longitudinal analyses (U.S. EPA, 2019a, Table 8-25, section 8.4.5). Associations of long-term exposure with neurodevelopmental effects are not consistently reported in children (U.S. EPA, 2019a, sections 8.4.4 and 8.4.5). Uncertainties in these studies include the potential for copollutant confounding, as no studies examined copollutants models (U.S. EPA, 2019a, section 8.4.5), and for exposure measurement error, given the use of various methods to estimate PM
                        <E T="52">10-2.5</E>
                         concentrations (U.S. EPA, 2019a, Table 8-25). In addition, there is limited animal toxicological evidence supporting the biological plausibility of nervous system effects (U.S. EPA, 2019a, sections 8.4.1 and 8.4.5).

In so doing, the Administrator has taken into account both evidence-based and quantitative information-based considerations, as well as advice from the CASAC and public comments. Evidence-based considerations draw upon the EPA's integrated synthesis of the scientific evidence from animal toxicologic, controlled human exposure, and epidemiologic studies evaluating health effects related to exposures to PM

                         as presented in the 2019 ISA and discussed in section III.A.2. In addition to the evidence, the Administrator has weighed a range of policy-relevant considerations as discussed in the 2022 PA and summarized in sections III.B and III.C of the proposal and summarized in section III.B.2 below. These considerations, along with the advice from the CASAC (section III.B.1) and public comments (section III.B.3), are discussed below.

                        As described in section I.X, the EPA decided to prepare a revised PA for the reconsideration of the 2020 final decision. The CASAC's advice on the 2019 draft PA and the 2021 draft PA was documented in letters to the prior and current Administrators (Cox, 2019b; Sheppard, 2022a) and is summarized below. In reviewing both the 2019 draft PA and the 2021 draft PA, the CASAC agreed with the EPA's preliminary conclusion that the available scientific evidence, including its uncertainties and limitations, does not call into question the adequacy of the current primary PM
                        <E T="52">10</E>
                         standard and that the standard should be retained, without revision.

                    <P>
                        In its review of the 2019 draft PA, the CASAC concurred with the overall preliminary conclusion that it is appropriate to consider retaining the current primary PM
                        <E T="52">10</E>
                         standard, without revision. In their agreement with the conclusions in the 2019 draft PA, the CASAC stated that “that key uncertainties identified in the last review remain” (Cox, 2019b) and that “none of the identified health outcomes linked to PM
                        <E T="52">10-2.5</E>
                        ” were judged to be causal or likely to be causal (Cox, 2019b, p. 12 of consensus responses). Moreover, to reduce these uncertainties in future reviews, the CASAC recommended improvements to PM
                        <E T="52">10-2.5</E>
                         exposure assessment, including a more extensive network for direct monitoring of the PM

                         fraction (Cox, 2019b, p. 13 of consensus responses). The CASAC also recommended additional controlled human exposure and animal toxicological studies of the PM
                        <E T="52">10-2.5</E>
                         fraction to improve the understanding of biological mechanisms and pathways (Cox, 2019b, p. 13 of consensus responses). Overall, the CASAC agreed with the EPA's preliminary conclusion in the 2019 draft PA that “. . . the available evidence does not call into question the adequacy of the public health protection afforded by the current primary PM
                        <E T="52">10</E>
                         standard and that evidence supports consideration of retaining the current standard in this review” (Cox, 2019b, p. 3 of letter).

                        . In this context, the CASAC supported the preliminary conclusion in the 2021 draft PA that the evidence reviewed in the 2019 ISA does not call into question the public health protection provided by the current primary PM

                         is an appropriate choice as the indicator for PM

                         studies, the more limited number of epidemiology studies with positive statistically significant findings, and the difficulty in extracting the sole contribution of coarse PM to observed adverse health effects” (Sheppard, 2022a, p. 19 of consensus responses).

                        At the time of the proposal, the Administrator carefully considered the assessment of the current evidence and conclusions reached in the 2019 ISA, considerations and staff conclusions and associated rationales presented in the 2020 PA and 2022 PA, and advice and recommendations of the CASAC (88 FR 5634, January 27, 2023). Consistent with previous reviews, the Administrator first considered the available scientific evidence for PM
                        <E T="52">10-2.5</E>
                        -related exposures and health effects, as evaluated in the 2019 ISA. As an initial matter, the Administrator recognized that the scientific evidence for PM

                        the evidence for several PM
                        <E T="52">10-2.5</E>
                        -related health effects has expanded since the completion of the 2009 ISA, but important uncertainties remain. The uncertainties in the epidemiologic studies contribute to the determinations in the 2019 ISA that the evidence for short and long-term PM
                        <E T="52">10-2.5</E>
                         exposures and mortality, cardiovascular effects, metabolic effects, nervous system effects, and cancer is “suggestive of, but not sufficient to infer” causal relationships (U.S. EPA, 2019a; U.S. EPA, 2022b, section 4.3.1). Drawing from the evidence evaluated in the 2019 ISA and consideration of the scientific evidence in the 2022 PA, the Administrator noted that, consistent with previous reviews, the 2019 ISA and the 2022 PA highlight a number of uncertainties associated with the evidence, including: (1) PM
                        <E T="52">10-2.5</E>
                         exposure estimates used in epidemiologic studies, (2) independence of PM
                        <E T="52">10-2.5</E>
                         health effect associations, and (3) biological plausibility of the PM
                        <E T="52">10-2.5</E>
                        -related effects. These uncertainties contribute to the determinations in the 2019 ISA that the evidence for short-term PM
                        <E T="52">10-2.5</E>
                         exposures and key health effects is “suggestive of, but not sufficient to infer” causal relationships. In considering the available scientific evidence, consistent with approaches employed in past NAAQS reviews, the Administrator placed the most weight on evidence supporting “causal” and “likely to be causal” relationships. In so doing, he noted that the available evidence for short- and long-term PM
                        <E T="52">10-2.5</E>
                         exposures and health effects does not support causality determinations of a “causal relationship” or “likely to be causal relationship.” Furthermore, the Administrator recognized that, because of the uncertainties and limitations in the evidence base, the 2022 PA does not include a quantitative assessment of PM
                        <E T="52">10-2.5</E>
                         exposures and risk that might further inform decisions regarding the adequacy of the current 24-hour primary PM
                        <E T="52">10</E>
                         standard. Therefore, in light of the 2019 ISA conclusions that the evidence supports “suggestive of, but not sufficient to infer” causal relationships. The Administrator judged that there are substantial uncertainties that raise questions regarding the degree to which additional public health improvements would be achieved by revising the existing PM
                        <E T="52">10</E>
                         standard. In considering the available evidence for long-term PM
                        <E T="52">10-2.5</E>
                         exposures, the Administrator noted that there is limited evidence that would support consideration of an annual standard to provide protection against such effects, in conjunction with the current primary 24-hour PM
                        <E T="52">10</E>
                         standard. He preliminarily concluded that the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard that reduces 24-hour exposures also likely reduces long-term average exposures, and therefore provides some margin of safety against the health effects associated with long-term PM
                        <E T="52">10-2.5</E>
                         exposures.

                        In reaching his proposed decision on the adequacy of the current primary 24-hour PM
                        <E T="52">10</E>
                         standard, the Administrator also considered advice from the CASAC. As noted above in section III.B.1, the CASAC recognized uncertainties associated with the scientific evidence and agreed with the 2019 draft PA and 2021 draft PA conclusions that the scientific evidence does not call into question the adequacy of the primary PM
                        <E T="52">10</E>
                         standard and supports consideration of retaining the current standard.

                    <P>
                        When considering the above information together, the Administrator proposed to conclude that the available scientific evidence continues to support a PM
                        <E T="52">10</E>
                         standard to provide some measure of protection against PM
                        <E T="52">10-2.5</E>
                         exposures. Additionally, he recognized that there are important uncertainties and limitations associated with the available evidence for PM
                        <E T="52">10-2.5</E>
                        -related health effects, for both short and long-term exposure, as evaluated in the 2019 ISA. Consistent with the decisions in the previous reviews, the Administrator proposed to conclude that these limitations lead to considerable uncertainty regarding the potential public health implications of revising the level of the current primary 24-hour PM
                        <E T="52">10</E>
                         standard. Thus, based on his consideration of the evidence and associated uncertainties and limitations for PM
                        <E T="52">10-2.5</E>
                        -related health effects and his consideration of CASAC advice on the primary PM
                        <E T="52">10</E>
                         standard, the Administrator proposed to retain the current primary PM
                        <E T="52">10</E>
                         standard, without revision.

                        Of the public comments received on the proposal, very few commenters provided comments on the primary PM

                         standard. Of those commenters who did provide comments on the primary PM

                         standard, the majority agree with the EPA's proposed decision to retain the primary PM

                         standard. In so doing, these commenters agree with the EPA's rationale regarding the available scientific information, including uncertainties and limitations, for informing decisions on the standard. These commenters state that no new scientific evidence or quantitative information has emerged since the 2020 decision to retain the current standard. Furthermore, these commenters note that the EPA did not evaluate any new scientific evidence related to PM
                        <E T="52">10-2.5</E>
                         exposures and health effects as a part of the 2022 ISA Supplement developed for this reconsideration, nor did the revised 2022 PA consider any new or different information from the 2020 PA, and therefore, the EPA reached the same conclusion as is the 2020 PA that the current standard is adequate and should be retained. This group includes industries and industry groups, as well as some State and local governments. All of these commenters generally note their agreements with the rationale provided in the proposal and the CASAC concurrence with the 2021 draft PA conclusion that the available information does not call into question the adequacy of the current standard, and therefore, does not support revision and that the current standard should be retained.

                        Some commenters, including those from environmental and public health organizations and groups, some states, and individuals, disagreed with the Administrator's proposed decision to retain the current primary PM

                        Commenters who disagreed with the proposal to retain the current standard state that revision to the primary PM

                         standard is necessary to protect public health with an adequate margin of safety. In their recommendations for revising the standard, some commenters contend that the current standard, with its indicator of PM

                         have been reduced with revisions to that standard. These commenters assert that the current primary PM

                         would allow proportionately more PM

                        -related health effects has been expanded and strengthened since the time of the last review. Taken together, the commenters contend that the primary PM

                         fraction of PM
                        <E T="52">10</E>
                         could increase in some areas as the PM
                        <E T="52">2.5</E>
                         fraction decreases (78 FR 3085, March 03, 2013). As described in the 2019 ISA, PM
                        <E T="52">10</E>
                         has become considerably coarser across the U.S. compared to similar observations in the 2009 ISA such that, in urban areas, the mass of the coarse fraction of PM is similar to or greater than the mass of the fine fraction of PM (U.S. EPA, 2019, section 2.5.1.1.4; U.S. EPA, 2009c). However, in considering recent air quality data, the EPA notes that in most areas of the country PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         concentrations have declined and are well below their respective 24-hour standards. While the contribution of fine and coarse PM to PM
                        <E T="52">10</E>
                         mass concentrations may vary spatially and temporally, based on the trends in recent air quality data, the Administrator concludes that the current primary 24-hour PM
                        <E T="52">10</E>
                         standard is maintaining air quality at level that provides requisite protection against PM
                        <E T="52">10-2.5</E>
                        . That is, recent air quality data does not suggest that PM
                        <E T="52">10-2.5</E>
                         concentrations have been increasing as PM
                        <E T="52">2.5</E>
                         concentrations have been decreasing. In considering the available PM
                        <E T="52">10-2.5</E>
                         health effects evidence in this reconsideration, there continue to be significant uncertainties and limitations, specifically with respect to the exposure assessment methods used to estimate PM
                        <E T="52">10-2.5</E>
                         concentrations, that make it difficult to fully assess the public health implications of revising the primary PM
                        <E T="52">10</E>
                         standard even considering the possibility for additional variability in the relative ratio of PM
                        <E T="52">2.5</E>
                         to PM
                        <E T="52">10-2.5</E>
                         in current PM
                        <E T="52">10</E>
                         air quality across the U.S. As described in detail above in section III.A.2 and in the proposal (85 FR 5558, January 27, 2023), the uncertainties and limitations in the health effects evidence for PM
                        <E T="52">10-2.5</E>
                         contributed to the determinations in the 2019 ISA that the evidence for key PM
                        <E T="52">10-2.5</E>
                         health effects is “suggestive of, but not sufficient to infer, a causal relationship” or “inadequate to infer the presence, or absence of a causal relationship” (U.S. EPA, 2019a). While the evidence base for PM
                        <E T="52">10-2.5</E>
                        -related health effects has somewhat expanded since the 2009 ISA, the Administrator concludes that the evidence remains too limited to inform judgments regarding whether a more protective primary PM
                        <E T="52">10</E>
                         standard is warranted at this time.

                    <P>
                        Beyond the uncertainties and limitations associated with the available scientific evidence, the EPA also notes that, while the NCore monitoring network has been expanded since the time of the last review, epidemiologic studies available in this review do not use PM
                        <E T="52">10-2.5</E>
                         NCore data in evaluating associations between PM
                        <E T="52">10-2.5</E>
                         in ambient air and long- or short-term exposures. In the absence of such evidence, the public health implications of changes in ambient PM
                        <E T="52">10-2.5</E>
                         concentrations as PM
                        <E T="52">2.5</E>
                         concentrations decrease remain unclear. Therefore, the EPA continues to recognize this as an area for future research, to address the existing uncertainties (U.S. EPA, 2022b, section 4.6), and inform future reviews of the PM NAAQS. Taken together, as at the time of proposal, the Administrator concludes that these and other limitations in the PM
                        <E T="52">10-2.5</E>
                         evidence raised questions as to whether additional public health improvements would be achieved by revising the existing PM
                        <E T="52">10</E>
                         standard, particularly when considering such judgments along with his decision to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. Therefore, the EPA does not agree with the commenters that the currently available air quality information or scientific evidence support revisions to the primary PM
                        <E T="52">10</E>
                         standard in this reconsideration.
                    </P>
                    <P>
                        Consistent with their comments on the 2020 proposal, some commenters disagreed with the Administrator's proposed conclusion to retain the current primary PM
                        <E T="52">10</E>
                         standard, primarily focusing their comments on the need for revisions to the form of the standard or the level of the standard. With regard to comments on the form of the standard, some commenters assert that the EPA should revise the standard by adopting a separate form (or a “compliance threshold” in their words)—the 99th percentile, averaged over three years—for the primary PM
                        <E T="52">10</E>
                         standard for continuous monitors, which provide data every day, while maintaining the current form of the standard (one exceedance, averaged over three years) for 1-in-6 samplers, given the increased use of continuous monitoring and to ease the burden of demonstrating exceptional events. These commenters, in support of their comment, contend that the 99th percentile would effectively change the form from the 2nd highest to the 4th highest and would allow no more than three exceedances per year, averaged over three years. These commenters additionally highlight the EPA's decision in the 1997 review to adopt a 99th percentile form, averaged over three years, citing to advantages of a percentile-based form in the Administrator's rationale in that review. The comments further assert that a 99th percentile form for the primary PM
                        <E T="52">10</E>
                         standard is still more conservative than the form for other short-term NAAQS (
                        <E T="03">e.g.,</E>
                         PM
                        <E T="52">2.5</E>
                         and NO
                        <E T="52">2</E>
                        ).
                        <PRTPAGE P="16299"/>
                    </P>
                    <P>
                        First, the EPA has long recognized that the form is an integral part of the NAAQS and must be selected together with the other elements (
                        <E T="03">i.e.,</E>
                         indicator, averaging time, level) of the NAAQS to ensure the appropriate stringency and requisite degree of public health protection. Thus, if the EPA were to change the form according to the monitoring method it would be establishing two different NAAQS, varying based on the monitoring method. The EPA has not done this to date, did not propose such an approach, and declines to adopt it for the final rule, as we believe such a decision in this final rule is beyond the scope of the proposal, and that each PM standard should have a single form, indicator, level and averaging time, chosen by the Administrator as necessary and appropriate. While certain continuous monitors may be established and approved as a Federal Equivalent Method (FEM) for PM
                        <E T="52">10</E>
                        , as an alternative to a Federal Reference Method (FRM), the use of an FEM is intended as an alternative means of determining compliance with the NAAQS, not as authorizing a different NAAQS.
                    </P>
                    <P>
                        Even if the commenters had asked that the change in form be made without regard to monitoring method, the EPA does not believe such a change would be warranted. The change in form for continuous monitors suggested by the commenters, without also lowering the level of such a standard, would allow more exceedances and thereby reduce the public health protection provided against exposures to PM
                        <E T="52">10-2.5</E>
                         in ambient air, resulting in a less stringent primary PM
                        <E T="52">10</E>
                         standard than the current standard. These commenters have not provided new evidence or analyses to support their conclusion that an appropriate degree of public health protection could be achieved by allowing the use of an alternative form (
                        <E T="03">i.e.,</E>
                         99th percentile), while retaining the other elements of the standard.
                    </P>
                    <P>
                        With regard to the commenters' assertion that an alternate form of the standard would ease the burden of demonstrating exceptional events, the EPA recognizes, consistent with the CAA, that it may be appropriate to exclude monitoring data influenced by “exceptional” events when making certain regulatory determinations. However, the EPA notes that the cost of implementation of the standards may not be considered by the EPA in reviewing the standards. The EPA continues to update and develop documentation and tools to facilitate the implementation of the 2016 Exceptional Events Rule, including new PM
                        <E T="52">2.5</E>
                         implementation focused products under development that are intended to assist air agencies with the development of demonstrations for specific types of exceptional events. With regard to the commenters' specific concerns for wildfires or high winds, the EPA released updated guidance documents on the preparation of exceptional event demonstrations related to wildfires in September 2016, high wind dust events in April 2019, and prescribed fires in August 2019. These guidance documents outline the regulatory requirements and provide examples for air agencies preparing demonstrations for wildfires, high wind dust, and prescribed fire events. For all of the reasons discussed above, the EPA does not agree with the commenters that the form of the primary PM
                        <E T="52">10</E>
                         standard should be revised to a 99th percentile for continuous monitors.

                    <P>
                        This section summarizes the Administrator's considerations and conclusions related to the current primary PM
                        <E T="52">10</E>
                         standard. In establishing primary standards under the Act that are “requisite” to protect the public health with an adequate margin of safety, the Administrator is seeking to establish standards that are neither more nor less stringent than necessary for this purpose. In so doing, the Administrator notes that his final decision in this reconsideration is a public health policy judgment that draws upon scientific information, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the information. Accordingly, he recognizes that his decision requires judgments based on the interpretation of the evidence that neither overstates nor understates the strength or limitations of the evidence nor the appropriate inferences to be drawn. He recognizes, as described in section I.A above, that the Act does not require that primary standards be set at a zero-risk level; rather, the NAAQS must be sufficient but not more stringent than necessary to protect public health, including the health of sensitive groups with an adequate margin of safety.

                        Given these requirements, and consistent with the primary PM
                        <E T="52">2.5</E>
                         standards discussed above (section II.C.3), the Administrator's final decision in this reconsideration of the current primary PM
                        <E T="52">10</E>
                         standard will be a public health policy judgment that draws upon the scientific information examining the health effects of PM
                        <E T="52">10-2.5</E>
                         exposures, including how to consider the range and magnitude of uncertainties inherent in that information. The Administrator's final decision is based on an interpretation of the scientific evidence that neither overstates nor understates its strengths and limitations, nor the appropriate inferences to be drawn.

                    <P>
                        Having carefully considered advice from the CASAC and public comments, as discussed above, the Administrator notes that the fundamental scientific conclusions on health effects of PM
                        <E T="52">10-2.5</E>
                         in ambient air that were reached in the 2019 ISA and summarized in the 2020 PA and 2022 PA remain valid. Additionally, the Administrator believes the judgments he proposed (85 FR 5558, January 27, 2023) with regard to the evidence remain appropriate. Further, in considering the adequacy of the current primary PM
                        <E T="52">10</E>
                         standard in this reconsideration, the Administrator has carefully considered the policy-relevant evidence and conclusions contained in the 2019 ISA; the rationale and conclusions presented in the 2020 PA and 2022 PA; the advice and recommendations from the CASAC in their reviews of the 2019 draft PA and 2021 draft PA; and public comments, as addressed in section III.B.3 above and in the RTC document. In the discussion below, the Administrator gives weight to the conclusions in the 2020 PA and 2022 PA, with which the CASAC has concurred, as summarized in section III.C of the proposal and takes note of the key aspects of the rationale for those conclusions that contribute to his decision in this review. In considering this information, the Administrator concludes that the preliminary conclusions and policy judgments supporting his proposed decision remain valid, and that the current primary PM
                        <E T="52">10</E>
                         standard provides requisite protection of public health with an adequate margin of safety and should be retained. In considering the 2020 PA and 2022 PA evaluations and conclusions, the Administrator notes that, while the health effects evidence is somewhat expanded since the 2009 ISA as described in section III.A.2 above, the overall conclusions are generally consistent with those reached in the 2009 ISA (U.S. EPA, 2020b, section 4.4). In so doing, he additionally notes that the CASAC supported the preliminary conclusion in the 2019 draft PA and 2021 draft PA that the evidence reviewed in the 2019 ISA does not call into question the public health protection provided by the current primary PM
                        <E T="52">10</E>

                        <E T="52">10</E>

                    <P>
                        As noted below, the scientific evidence for PM
                        <E T="52">10-2.5</E>
                        -related health effects has expanded somewhat since the 2012 review, in particular for long-term exposures. The Administrator recognizes, however, that there are a number of uncertainties and limitations associated with the available information, as described in the proposal (85 FR 5558, January 27, 2023) and below. With regard to the current evidence on PM
                        <E T="52">10-2.5</E>
                        -related health effects, the Administrator takes note of recent epidemiologic studies that continue to report positive associations with mortality and morbidity in cities across North America, Europe, and Asia, where PM
                        <E T="52">10-2.5</E>
                         sources and composition are expected to vary widely. While significant uncertainties remain, as described below, the Administrator recognizes that this expanded body of evidence has broadened the range of effects that have been linked with PM
                        <E T="52">10-2.5</E>
                         exposures. These studies provide an important part of the scientific foundation supporting the 2019 ISA's revised causality determinations (and new determinations) for long-term PM
                        <E T="52">10-2.5</E>
                         exposures and mortality, cardiovascular effects, metabolic effects, nervous system effects, and cancer (U.S. EPA, 2019a; U.S. EPA, 2022b, section 4.2). Drawing from his consideration of this evidence, the Administrator concludes that the available scientific information supports a decision to maintain a primary PM
                        <E T="52">10</E>
                         standard to provide public health protection against PM
                        <E T="52">10-2.5</E>
                         exposures, regardless of location, source of origin, or particle composition. With regard to uncertainties in the evidence, the Administrator first notes that a number of limitations were identified in the 2012 review related to: (1) Estimates of ambient PM
                        <E T="52">10-2.5</E>
                         concentrations used in epidemiologic studies; (2) limited evaluation of copollutant models to address the potential for confounding; and (3) limited experimental studies supporting biological plausibility for PM
                        <E T="52">10-2.5</E>
                        -related effects. Despite the expanded body of evidence for PM
                        <E T="52">10-2.5</E>
                         exposures and health effects assessed in the 2019 ISA, the Administrator recognizes that uncertainties remain, similar to those in the 2012 review. As summarized in section III.A.2 above and in responding to public comments, uncertainties in the available scientific evidence continue to include those associated with the exposure estimates used in epidemiologic studies, the independence of the PM
                        <E T="52">10-2.5</E>
                         health effect associations, and the biologically plausible pathways for PM
                        <E T="52">10-2.5</E>
                         health effects (U.S. EPA, 2022b, section 4.3). These uncertainties contribute to the 2019 ISA determinations that the evidence is “suggestive of, but not sufficient to infer” causal relationships (U.S. EPA, 2019a). The Administrator recognizes that the NAAQS must allow for a margin of safety but also places emphasis on evidence supporting “causal” or “likely to be causal” relationships (as described in sections II.A.2 and III.A.2 above). Finding that there is too much uncertainty that a more stringent standard would improve public health, the Administrator judges that the available evidence provides support for his conclusion that the current standard provides the requisite level of protection from the effects of PM
                        <E T="52">10-2.5</E>
                        . In making this judgment, the Administrator considers whether this level of protection is more than what is requisite and whether a less stringent standard would be appropriate to consider. He notes that there continues to be uncertainty associated with the evidence, as reflected by the “suggestive of, but not sufficient to infer” causal determinations. The Administrator recognizes that the CAA requirement that primary standards provide an adequate margin of safety, as summarized in section I.A above, is intended to address uncertainties associated with inconclusive scientific evidence and technical information, as well as to provide a reasonable degree of protection against hazards that research has not yet identified. In light of these considerations and the current body of evidence, including uncertainties and limitations, the Administrator concludes that a less stringent standard would not provide the requisite protection of public health, including an adequate margin of safety. The Administrator also considers whether the level of protection associated with the current standard is less than what is requisite and whether a more stringent standard would be appropriate to consider. In so doing, the Administrator considers, as discussed above, the level of protection offered from exposures for which public health implications are less clear. In so doing, he again notes the significant uncertainties and limitations that persist in the scientific evidence. In particular, he notes limitations in the approaches used to estimate ambient PM
                        <E T="52">10-2.5</E>
                         concentrations in epidemiologic studies, limited examination of the potential for confounding by co-occurring pollutants, and limited support for the biological plausibility of the serious effects reported in many epidemiologic studies that are reflected by the “suggestive of, but not sufficient to infer” causal determinations. Thus, in light of the currently available information, including the uncertainties and limitations of the evidence base available to inform his judgments regarding protection against PM
                        <E T="52">10-2.5</E>
                        -related effects, the Administrator does not find it appropriate to increase the stringency of the standard in order to provide the requisite public health protection. Rather, he judges it appropriate to maintain the level of protection provided by the current primary PM
                        <E T="52">10</E>
                         standard for PM
                        <E T="52">10-2.5</E>
                         exposures and he does not judge that the available information and the associated uncertainties indicate the need for a greater level of public health protection.

                        In reaching his conclusions on the primary PM
                        <E T="52">10</E>
                         standard, the Administrator also considers advice from the CASAC. In their comments, the CASAC noted that uncertainties that were identified in the 2012 review persist in the evidence for PM
                        <E T="52">10-2.5</E>
                        -related health effects (Cox, 2019b, p. 13 of consensus responses; Sheppard, 2022a, p. 4 of consensus letter) In considering these comments, the Administrator takes note of the CASAC consideration of the evidence, and associated uncertainties, and its conclusion that the evidence reviewed in the 2019 ISA does not call into question the adequacy of the public health protection afforded by the current primary PM
                        <E T="52">10</E>
                         standard (Cox, 2019b, p. 3 of letter; Sheppard, 2022a, p. 4 of consensus letter). The Administrator further notes the unanimous conclusions of the CASAC that evidence supports consideration of retaining the current primary PM
                        <E T="52">10</E>
                         standard (Cox, 2019b, p. 3 of consensus letter; Sheppard, 2022a, p. 4 of consensus letter). In addition to the CASAC's advice, the Administrator also considers public comments, the majority of which supported retaining the primary PM
                        <E T="52">10</E>
                         standard, citing to and agreeing with the Administrator's rationale for his proposed decision. The Administrator also recognizes that a few public commenters supported revising the primary PM

                         standard in order to provide increased protection against PM
                        <E T="52">10-2.5</E>

                        The Administrator also notes that the scientific record for his decision on the primary PM

                         standard is the same as the record before the then-Administrator in 2020, as the scope of the ISA Supplement focused on health effect categories where the 2019 ISA concluded a causal relationship (

                         exposure and cardiovascular effects and mortality). Therefore, because no health outcome categories for short- or long-term PM
                        <E T="52">10-2.5</E>
                         exposure in the 2019 ISA were greater than “suggestive of, but not sufficient to infer, a causal relationship”, the ISA Supplement did not evaluate studies published after the literature cutoff date of the 2019 ISA related to PM

                         exposures and health effects. The Administrator further notes his decision is consistent with the decision of the prior Administrator in 2020 to retain the primary PM

                         standard.

                         standard, the Administrator recognizes that the 2022 PA notes that the evidence continues to support retaining the PM

                        -related effects. He notes that, consistent with the approaches in previous reviews, a standard with a PM
                        <E T="52">10</E>
                         mass-based indicator, in conjunction with a PM
                        <E T="52">2.5</E>
                         mass-based standard, will result in controlling allowable concentrations of PM
                        <E T="52">10-2.5</E>
                        . The Administrator also takes note of the 2019 ISA comparison that showed that the relative contribution of PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10-2.5</E>
                         to PM
                        <E T="52">10</E>
                         concentrations can vary across the U.S. by region and season, with urban locations having a somewhat higher contribution of PM
                        <E T="52">2.5</E>
                         contributing to PM
                        <E T="52">10</E>
                         concentrations than PM
                        <E T="52">10-2.5</E>
                         (U.S. EPA, 2019a, section 2.5.1.1.4, Table 2-7). In these urban locations, where PM
                        <E T="52">2.5</E>
                         concentrations are somewhat higher than in rural locations, the toxicity of the PM
                        <E T="52">10</E>
                         may be higher due to contaminating PM
                        <E T="52">2.5</E>
                        . Further, although uncertainties with the evidence persist, the strongest health effects evidence associated with PM
                        <E T="52">10-2.5</E>
                         comes from epidemiologic studies conducted in urban areas. He also notes that the CASAC agreed with the EPA's conclusions that a PM
                        <E T="52">10</E>
                         indicator remained appropriate (Cox, 2019b, p. 13 of consensus responses; Sheppard, 2022a, p. 4 of letter). In light of this information, the Administrator concludes that the PM
                        <E T="52">10</E>
                         indicator remains appropriate and provides protection from exposure to all coarse PM, regardless of location, source of origin, or particle composition.

                        Similarly, with regard to averaging time, form, and level of the standard, the Administrator takes note of uncertainties in the available evidence and information and continues to find that the current standard, as defined by in all of its elements, is requisite. As an initial matter, the Administrator notes that the current primary PM
                        <E T="52">10</E>
                         standard, with its level of 150 µg/m
                        <SU>3</SU>
                        , 24-hour averaging time, not to be exceeded more than once per year on average over three years, is intended to protect against short-term peak PM
                        <E T="52">10-2.5</E>
                         exposures. In so doing, while the Administrator notes that changes in PM
                        <E T="52">2.5</E>
                         concentrations in ambient air can influence the contribution of the fine and coarse fractions to PM
                        <E T="52">10</E>
                         mass, such that reductions in PM
                        <E T="52">2.5</E>
                         concentrations can lead to more allowable PM
                        <E T="52">10-2.5</E>
                         under the current primary PM
                        <E T="52">10</E>
                         standard, he recognizes that there is no new information available in this reconsideration to suggest that the public health protection provided by the current standard is not requisite or that a more stringent standard is warranted at this time. The Administrator concludes that, particularly in light of his decision to retain the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard with its level of 35 µg/m
                        <SU>3</SU>
                         as described in section II.B.4 above, the primary PM
                        <E T="52">10</E>
                         standard would be expected to maintain PM
                        <E T="52">10-2.5</E>
                         concentrations in ambient air below those that have been considered to be associated with serious health effects in past NAAQS reviews. The Administrator also notes that while the scientific evidence available in the 2019 ISA has expanded since the completion of the 2009 ISA, he concludes that this information does not provide support for the causal or likely to be causal relationships upon which he places the greatest weight in considering the adequacy of the current standards. He further concludes that the uncertainties and limitations of the scientific evidence, along with the absence of information to inform a quantitative exposure or risk assessment, make it difficult to reach decisions regarding whether a more protective standard is warranted at this time. He has additionally considered the public comments regarding revisions to these elements of the standard and continues to judge that the existing level and the existing form, in all its aspects, together with the other elements of the existing standard provide an appropriate level of public health protection. For all of the reasons discussed above and recognizing the CASAC's conclusion that the current evidence provides support for retaining the current standard, the Administrator concludes that the current primary PM
                        <E T="52">10</E>
                         standard (in all of its elements) is requisite to protect public health with an adequate margin of safety from effects of PM
                        <E T="52">10-2.5</E>
                         in ambient air and should be retained without revision.

                             In 1976, the EPA established a nationally uniform air quality index, then called the Pollutant Standard Index (PSI), for use by State and local agencies on a voluntary basis (41 FR 37660, September 7, 1976; 52 FR 24634, July 1,1987). In August 1999, the EPA adopted revisions to this air quality index (64 FR 42530, August 4, 1999) and renamed the index the AQI.

                        The AQI converts an individual pollutant concentration in a community's air to a number on a scale from 0 to 500. Reported AQI values for specific pollutants enable the public to know whether air pollution levels in a particular location are characterized as good (0-50), moderate (51-100), unhealthy for sensitive groups (101-150), unhealthy (151-200), very unhealthy (201-300), or hazardous (301+). Across criteria pollutants, the AQI value of 100 typically corresponds to the level of the short-term (
                        <E T="03">e.g.,</E>
                         24-hour, 8-hour, or 1-hour standard) NAAQS for each pollutant. Below an index value of 100, an intermediate value of 50 is defined either as the level of the annual standard if an annual standard has been established (
                        <E T="03">e.g.,</E>
                         PM

                        concentration equal to one-half the value of the 24-hour standard used to define an index value of 100 (
                        <E T="03">e.g.,</E>
                         carbon monoxide), or a concentration based directly on health effects evidence (
                        <E T="03">e.g.,</E>
                         ozone). An AQI value greater than 100 means that a pollutant is in one of the unhealthy categories (
                        <E T="03">i.e.,</E>
                         unhealthy for sensitive groups, unhealthy, very unhealthy, or hazardous). An AQI value at or below 100 means that a pollutant concentration is in one of the satisfactory categories (
                        <E T="03">i.e.,</E>
                         moderate or good). The scientific evidence on pollutant-related health effects for each NAAQS review support decisions related to pollutant concentrations at which to set the various AQI breakpoints, which delineate the AQI categories for each individual pollutant (
                        <E T="03">i.e.,</E>
                         the pollutant concentrations corresponding to index values of 150, 200, 300, and 500). The AQI is reported three ways by the EPA and State, local and Tribal agencies, all of which are useful and complementary. The daily AQI is reported for the previous day and used to observe trends in community air quality, the AQI forecast helps people plan their outdoor activities for the next day, and the near-real-time AQI, or NowCast AQI, tells people whether it is a good time for outdoor activity.

                        Historically, State and local agencies have primarily used the AQI to provide general information to the public about air quality and its relationship to public health. For more than two decades, many State and local agencies, as well as the EPA and other Federal agencies, have been developing new and innovative programs and initiatives to provide more information related to air quality and health messaging to the public in a more timely way. These initiatives, including air quality forecasting, near real-time data reporting through the AirNow website, use of data from air quality sensors on the EPA and U.S. Forest Service's (USFS) Fire and Smoke Map, and air quality action day programs, provide useful, up-to-date, and timely information to the public about air pollution and its health effects. Such information can help the public learn when their well-being may be compromised, so they can take actions to avoid or to reduce exposures to ambient air pollution at concentrations of concern. This information can also encourage the public to take actions that will reduce air pollution on days when concentrations are projected to be of concern to local communities (

                        One purpose of the AQI is to communicate to the public when air quality is poor and thus when they should consider taking actions to reduce their exposures. The higher the AQI value, the higher the level of air pollution and the greater the health concern. In recognition of the scientific information available that is informing the reconsideration of the 2020 final decision on the primary PM

                         standards, including a number of new controlled human exposure and epidemiologic studies published since the completion of the 2009 ISA, as well as additional epidemiologic studies from other peer reviewed documents that evaluate the health effects of wildfire smoke exposure and that can inform the selection of AQI breakpoints at higher PM

                         the EPA proposed to make two sets of changes to the PM

                         sub-index of the AQI. First, the EPA proposed to continue to use the approach used in the revisions to the AQI in 2012 (77 FR 38890, June 29, 2012) of setting the lower breakpoints (50, 100 and 150) to be based on the levels of the primary PM

                         annual and 24-hour standards and proposed to revise the lower breakpoints to be consistent with changes to the primary PM

                         standards that are part of this reconsideration. Second, the EPA proposed to revise the upper AQI breakpoints (200 and above) and to replace the linear-relationship approach used in 1999 to set these breakpoints, with an approach that more fully considers the PM
                        <E T="52">2.5</E>
                         health effects evidence from controlled human exposure and epidemiologic studies that have become available in the last 20 years (64 FR 42530, August 4, 1999).

                             In evaluating the scientific evidence available to inform decisions regarding the AQI breakpoints, the EPA considered studies that were included as a part of the 2019 ISA and ISA Supplement, but also considered other studies that were not included as a part of the review of the air quality criteria. The ISAs have specific criteria for study inclusion and consideration in reaching conclusions regarding causal relationships, and some studies that may not have met those criteria (

                    <P>
                        With respect to the lower AQI breakpoints in the proposal (88 FR 5638, January 27, 2023), the EPA proposed to conclude that it is appropriate to continue setting these breakpoints to be consistent with the primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standard levels. The lowest AQI value of 50 provides the breakpoint between the “good” and “moderate” categories. At and below this concentration, air quality is considered “good” for everyone. Above this concentration, in the “moderate” category, the AQI contains advisories for unusually sensitive individuals. The EPA has historically set this breakpoint at the level of the primary annual PM
                        <E T="52">2.5</E>
                         standard. In doing so, the EPA has recognized that: (1) The annual standard is set to provide protection to the public, including at-risk populations, from PM
                        <E T="52">2.5</E>
                         concentrations, which, when experienced on average for a year, have the potential to result in adverse health effects; and (2) the AQI exposure period represents a shorter exposure period (
                        <E T="03">e.g.,</E>
                         24-hour (or less)) while focusing on the most sensitive individuals. The EPA saw no basis for deviating from this approach in this reconsideration. Thus, the EPA proposed to set the AQI value of 50 at a daily (
                        <E T="03">i.e.,</E>
                         24-hour) average concentration equal to the level of the primary annual PM

                    <P>
                        The historical approach to setting an AQI value of 100, which is the breakpoint between the “moderate” and “unhealthy for sensitive groups” categories, and above which advisories are generated for sensitive groups, is to set it at the same level as the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, the EPA has recognized that the primary 24-hour PM
                        <E T="52">2.5</E>
                         standard is set to provide protection to the public, including at-risk populations, from short-term exposures to PM
                        <E T="52">2.5</E>
                         concentrations that have the potential to result in adverse health effects. Given this, it is appropriate to generate advisories for sensitive groups at concentrations above this level. In the past, State, local, and Tribal air quality agencies have expressed strong support for this approach (78 FR 3086, January 15, 2013). The EPA saw no basis to deviate 
                        <PRTPAGE P="16303"/>
                        from this approach in this reconsideration. In the proposal (88 FR 5638, January 27, 2023), the EPA proposed to retain the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard with its level of 35 μg/m

                         but took comment on revising the level of that standard to 25 μg/m

                         (section II.D.3.b). Thus, the EPA proposed to retain the AQI value of 100 set at the level of the current primary 24-hour PM
                        <E T="52">2.5</E>
                         standard concentration of 35 μg/m

                        With respect to an AQI value of 150, which is the breakpoint between the “unhealthy for sensitive groups” and “unhealthy categories,” this breakpoint concentration in this reconsideration is based upon the considering the same health effects information, as assessed in the 2019 ISA and ISA Supplement and described in section II above, that informs the proposed decisions on the level of the 24-hour standard and the AQI value of 100. Previously, the Agency has used a proportional adjustment in which the AQI value of 150 was set proportionally to the AQI value of 100. This proportional adjustment inherently recognizes that the available epidemiologic studies provide no evidence of discernible thresholds, below which effects do not occur in either sensitive groups or in the general population, that could inform conclusions regarding concentrations at which to set this breakpoint. Given that the epidemiologic evidence continues to be the most relevant health effects evidence for informing this range of AQI values, the EPA saw no basis to deviate from this approach in this reconsideration. Therefore, the EPA proposed to set an AQI value of 150 proportionally, depending on the breakpoint concentration of the AQI value of 100 (

                        In the proposal (88 FR 5639, January 27, 2023), the EPA summarized the history of setting the AQI values of 300 and above in the 1999 rule (64 FR 42530, August 4, 1999) and established breakpoints for PM
                        <E T="52">2.5</E>
                         in that range. In general, the AQI values between 100 and 500 were based on PM
                        <E T="52">2.5</E>
                         concentrations that generally reflected a linear relationship between increasing index values and increasing PM

                         concentrations.

                        <FTREF/>
                         It was found that this linear relationship was generally consistent with the health effects evidence, which suggested that as PM
                        <E T="52">2.5</E>
                         concentrations increase, increasingly larger numbers of people are likely to experience serious health effects in this range of PM

                         concentrations (64 FR 42536, August 4, 1999). For the AQI breakpoint of 500, the concentration was based on the method used to establish a previously existing PM

                         breakpoint that was informed by studies conducted in London using the British Smoke method, which uses a different particle size cutpoint as noted in the proposal (88 FR 5639, January 27, 2023). Due to limited ambient PM

                         monitoring data available at that time, the decision on the 500 value concentration for PM
                        <E T="52">2.5</E>
                         was based on the stated assumption that PM concentrations measured by the British Smoke method were approximately equivalent to PM
                        <E T="52">2.5</E>
                         concentrations (64 FR 42530, August 4, 1999). Given that the British Smoke method has a larger particle size cutpoint than the current PM

                         monitoring method, which has a cutpoint of 2.5 microns, a concentration of 500 μg/m
                        <SU>3</SU>
                         based on the British Smoke method would be equivalent to a lower PM

                         concentration. With respect to the upper breakpoints of the AQI, the EPA has historically been concerned about establishing these upper breakpoints using evidence based on larger size fractions of PM, given that PM
                        <E T="52">2.5</E>
                         is the indicator for the AQI. While monitoring data for higher PM

                         concentrations in ambient air has been available for many years, the health effects evidence has only recently become available for consideration in informing decisions on the upper breakpoints of the AQI.

                             The AQI breakpoint at 150 was originally set in 1999 to be linearly related to the concentrations at the 100 and 500 breakpoints but then revised in 2012 to be proportional to the AQI breakpoint concentration at 100 (78 FR 3181, January 15, 2013).

                        As part of this reconsideration, the EPA recognized that the health effects evidence associated with PM
                        <E T="52">2.5</E>
                         exposure has greatly expanded in recent years. Multiple controlled human exposure studies have become available that provide information about health effects across a range of concentrations. While many of the new studies evaluated in the 2019 ISA focused on examining health effects associated with exposure to lower PM
                        <E T="52">2.5</E>
                         concentrations, there are also several new controlled human exposure studies that provide information about the health effects observed in study participants at concentrations well above the standard levels. Additionally, there are also epidemiologic studies now available and evaluated in other Agency peer-reviewed documents that can inform health effects associated with higher PM
                        <E T="52">2.5</E>
                         concentrations (U.S. EPA, 2021b).

                        <FTREF/>
                         Thus, the EPA concluded that it is appropriate to reevaluate the upper AQI breakpoints, taking into account the expanded body of scientific evidence, particularly given several new epidemiologic studies conducted during high pollution events like wildfires and multiple controlled human exposure studies. While it remains unclear the exact PM
                        <E T="52">2.5</E>
                         concentrations at which specific health effects occur, the more recent studies do provide more refined information about the concentration range in which these effects might occur in some populations. These studies provide support for coherence of effects across scientific disciplines and potentially biologically plausible pathways for the overt population-level health effects observed in epidemiologic studies. Therefore, taking into account the short exposure time period in these studies (
                        <E T="03">e.g.,</E>
                         1-6 hours) and that the studies generally do not include at-risk (or sensitive) populations, but rather young, healthy adults, these studies, in conjunction with information from epidemiologic studies, the EPA preliminarily concluded it would be appropriate to be more cautionary and offer advisories to the public for reducing exposures at lower concentrations than recommended with the current AQI breakpoints.

                        The AQI value of 200 is the breakpoint between the “unhealthy” and “very unhealthy” categories. At AQI values above 200, the AQI would be providing a health warning that the risk of anyone experiencing a health effect following short-term exposures to these PM

                         concentrations has increased. To inform proposed decisions on this breakpoint, the EPA takes note of studies indicating the potential for respiratory or cardiovascular effects that are on their own representative of or are on the biologically plausible pathway to more serious health outcomes (
                        <E T="03">e.g.,</E>
                         emergency department visits, hospital admissions). The controlled human exposure studies evaluated in the 2009 and 2019 ISAs provide evidence of inflammation as well as cardiovascular effects in healthy subjects at and above 120 µg/m

One of these studies, Hutchinson et al. (2018), conducted a bidirectional case-crossover analysis to examine associations between wildfire-specific PM

Further, during the initial 5-day period of the wildfire event, the study observed that there was evidence of increases in a number of respiratory-related outcomes particularly ED visits for asthma, upper respiratory infection, respiratory symptoms, acute bronchitis, and all respiratory-related visits (Hutchinson et al., 2018). When examining the air quality during the wildfire event, PM
                        <E T="52">2.5</E>
                         concentrations were highest during the initial five days of the wildfire, with 24-hour average PM

                        When considering this collective body of evidence from controlled human exposure and epidemiologic studies, the Agency proposed to set an AQI value of 200 at a daily (

                        . As discussed above and in the proposal (88 FR 5640, January 27, 2023), this concentration is at the lower end of the concentrations consistently shown to be associated with respiratory and cardiovascular effects in controlled human exposure studies following short-term exposures (

                        The AQI value of 300 denotes the breakpoint between the “very unhealthy” and “hazardous” categories, and thus marks the beginning of the “hazardous” AQI category. At AQI values above 300, the AQI provides a health warning that everyone is likely to experience effects following short-term exposures to these PM

To inform decisions on this AQI breakpoint, the EPA takes note of controlled human exposure studies that consistently show subclinical effects which are often associated with more severe cardiovascular outcomes. As discussed above, Brook et al. (2009) reported a transient increase of 2.9 mm Hg in diastolic blood pressure in healthy subjects during the 2-hour exposure to a mean concentration of 148 µg/m

                        In addition to the controlled human exposure studies discussed above, the epidemiologic study conducted by DeFlorio-Barker et al. (2019) examined the relationship between wildfire smoke and cardiopulmonary hospitalizations among adults 65 years of age and older from 2008-2010 in 692 U.S. counties. The authors reported a 2.22% increase in all-cause respiratory hospitalizations on wildfire smoke days for a 10 µg/m
                        <SU>3</SU>

                         concentrations (DeFlorio-Barker et al., 2019). The maximum 24-hour average concentration in this study on wildfire smoke days was 212.5 µg/m

                         (DeFlorio-Barker et al., 2019). In considering this study, the EPA notes the increased probability that even healthy adults experience effects at this maximum exposure concentration, particularly given that this maximum concentration is near the exposure concentrations in controlled human exposure studies that consistently reported evidence of impaired vascular function and several that reported increases in blood pressure in healthy adults following 2-hour exposures.

                        Based on the information discussed above and in the proposal (88 FR 5640, January 27, 2023), the EPA proposed to revise the 300 level of the AQI, which marks the beginning of the “hazardous” AQI category, to a concentration that is consistent with the PM
                        <E T="52">2.5</E>
                         concentrations associated with health effects as reported in the controlled human exposure (Brook et al., 2009; Bellavia et al., 2013; Tong et al., 2015; Behbod et al., 2013) and epidemiologic studies (DeFlorio-Barker et al. (2019). Specifically, the Agency proposed to set an AQI value of 300 at a daily (
                        <E T="03">i.e.,</E>
                         24-hour average) PM

                        <SU>3</SU>
                        . This concentration falls between the 2-hour average concentrations reported in controlled human exposure studies found to be consistently associated, in healthy adults, with impaired vascular function and/or increases in blood pressure, which could both be a precursor to more severe cardiovascular effects following short-term (1- to 2-hour) exposures, and the maximum 24-hour average PM

The 500 value of the AQI is within the “hazardous” category but is specified and used to calculate the slope of the AQI values in the “hazardous category” above and below AQI values of 500. In the past, this breakpoint had a very prominent role in determining the current upper AQI values given that it was used as part of the linear relationship with the concentration at the AQI value of 100 to determine the AQI values of 200 and 300 in 1999 (64 FR 42530, August 4, 1999).</P>

                        As discussed above and in the proposal (88 FR 5641, January 27, 2023), the current breakpoint concentration for the 500 value of the AQI was set in 1999 at a 24-hour average PM
                        <E T="52">2.5</E>

                         and was based on studies conducted in London using the British Smoke method, which used a different particle size cutpoint and likely overestimated the PM
                        <E T="52">2.5</E>
                         concentration. In looking to improve upon that approach, the EPA considered several recent controlled human exposure studies that observe health effects that are on the biologically plausible pathway to more severe cardiovascular outcomes and note that these seem to follow exposures to high PM
                        <E T="52">2.5</E>
                         concentrations that are well above those typically observed in ambient air. More specifically, in controlled human exposure studies, Vieira et al. (2016a) and Vieira et al.

                        The controlled human exposure studies provide biological plausibility for results of epidemiologic studies that document increases in respiratory-related health care events during the wildfires. The collective evidence from controlled human exposure and epidemiologic studies, which includes decreases in stroke volume, increased arterial stiffness, impaired vascular function and respiratory-related healthcare encounters provide health-based evidence that informed the proposed decisions on the level of the AQI value of 500. Given the concentrations observed in these studies, the Agency proposed to revise the AQI value of 500 to a level set at a daily (

                        <E T="52">2.5</E>
                         standards and recent scientific evidence discussed in the proposal (88 FR 5558, January 27, 2023). However, we received specific comments on proposed revisions to the breakpoints in the lower end of the AQI, related to their linkage to the annual and daily PM
                        <E T="52">2.5</E>

                    <P>
                        Some commenters agreed with using the historical approach of setting the 50, 100 and 150 breakpoints of the AQI to be consistent with the primary PM
                        <E T="52">2.5</E>
                         standards. Some cited the reason that this approach creates consistent communication with respect to air quality and the standards, and this is how the other AQI sub-indices are set. A few commenters disagreed with the historical approach and suggested instead that the 50 breakpoint of the AQI should not be revised at all, or that the 50 and 100 breakpoints of the AQI should be supported directly by health data similar to the basis for the proposed 200, 300 and 500 breakpoints.
                    </P>
                    <P>The few commenters that disagreed with the historical approach of the 50 breakpoint of the AQI noted that setting a short-term breakpoint to annual standard was not logical since it is a long-term standard and not meant to be interpreted for short-term messaging with the AQI, in particular when reported hourly via the NowCast. These commenters also noted that additional studies are needed to identify the health impacts of short-term exposures at low concentrations. They also noted that lowering the 50 breakpoint of the AQI in conjunction with the annual standard may cause confusion with the public because some State programs and policy decisions are connected to the AQI while others are based on PM concentrations, which could lead to inconsistent messaging reducing the public's trust. These comments were supported by noting that revised breakpoints could lead to more moderate days than in the past, but the monitor values would be the same as before when the commenters considered it “healthy,” possibly eroding trust in air agencies' messaging. Commenters also noted if the breakpoints are revised, the public will not visually be able to detect the difference between what was considered a good AQI day versus a now moderate AQI day.</P>
                    <P>
                        The EPA disagrees with these commenters. With respect to setting a short-term breakpoint to the level of a much longer-term (annual) standard, setting the lower AQI breakpoints at the level of the annual and daily PM
                        <E T="52">2.5</E>
                         standards for communication purposes was discussed in the proposed reconsideration (88 FR 5558, January 27, 2023) and previously supported by State organizations in the 2012 PM Final Rule (77 FR 38890, June 29, 2012). Both the AQI and the Pollutant Standards Index, which came before it, have historically been normalized across pollutants by defining an index value of 50 and 100 as the numerical level of the annual (when defined) and short-term (
                        <E T="03">i.e.,</E>
                         averaging time of 24-hours or less) primary NAAQS for each pollutant. This approach clearly communicates the air quality to the public. The EPA considers this approach to be appropriate given the available evidence and structure of the standard. As discussed in section II.B above and in the notice of final rulemaking for the 2012 review (77 FR 38890, June 29, 2012), the primary annual and 24-hour PM
                        <E T="52">2.5</E>
                         standards work together in concert to provide public health protection. The annual PM
                        <E T="52">2.5</E>
                         standard is generally viewed as the principal means of providing public health protection against “typical” daily and annual PM
                        <E T="52">2.5</E>
                         exposures, while the 24-hour PM
                        <E T="52">2.5</E>
                         standard is generally viewed as a means of providing protection against short-term exposures to “peak” PM
                        <E T="52">2.5</E>
                         concentrations, such as can occur in areas with strong contributions from local or seasonal sources, even when annual average PM
                        <E T="52">2.5</E>
                         concentrations remain relatively low. Because the annual standard provides public health protection for typical daily PM
                        <E T="52">2.5</E>
                         exposures, the EPA thinks it is appropriate to use that level for the 50 breakpoint of the AQI and describe daily air quality at and below the level of the annual standard “Good.” Since an annual standard allows for days with air quality above that level, it is appropriate to call days just above it “Moderate.” If the 50 breakpoint of the AQI was set at a level above the annual standard, it would be possible for the majority of days to be called “good” in a year when an area exceeds the annual standard. This could cause confusion with the public about air quality if the general perception is that local air quality is “good,” but the area fails to meet the annual standard. In addition, the EPA continues to find it appropriate to use the NowCast with the PM
                        <E T="52">2.5</E>
                         AQI index to provide more real-time information to the public. As discussed in the AQI Technical Assistance Document, while the NowCast algorithm is approximating a 24-hour average exposure, it can reflect concentrations observed over shorter averaging times when air quality is changing rapidly (U.S. EPA, 2018a). The EPA continues to consider the use of the primary annual standard level suitable in the NowCast given the health evidence supporting the standard and given that the reported concentrations are an approximation of “typical” daily exposure. Additionally, the EPA reflects the nature of the NowCast in the associated health messaging.

                        With regard to the commenter stating the public may not be able to visually detect a difference in the air quality, the EPA notes that the AQI is intended to be a communication tool for public awareness precisely because it is generally difficult for the public to visually judge air quality risks when air pollution is “moderate.” Moreover, since the establishment of the AQI, the EPA and State and local air agencies and organizations have developed experience in educating the public about changes in the standards and, 
                        <PRTPAGE P="16307"/>
                        concurrently, related changes to AQI breakpoints and advisories. When the standards change, the EPA and State and local agencies have sought to help the public understand that air quality is not getting worse, it's that the health evidence underlying the standards and the AQI has changed. The EPA's Air Quality System (AQS), the primary repository for air quality monitoring data, is also adjusted to reflect the revised breakpoints. Specifically, all historical AQI values in AQS are recomputed with the revised breakpoints, so that all data queries and reports downstream of AQS will show appropriate trends in AQI values over time. If any State, local or Tribal air agency is concerned that people are or will be confused on a moderate AQI day, then they could use the communication information that has been developed with this rulemaking.

                    <P>
                        Some commenters stated that the AQI should not necessarily be linked to the primary PM
                        <E T="52">2.5</E>
                         standards. One example is the comment that if the annual standard is not lowered to 8 µg/m
                        <SU>3</SU>
                        , the EPA should lower the 50 breakpoint of the AQI to that level to better inform the public of the need for behavioral modifications to reduce the harm to health from PM
                        <E T="52">2.5</E>
                         exposure. Similar to the reasons discussed above, the EPA concludes that setting the 50 breakpoint of the AQI at the level of the annual PM
                        <E T="52">2.5</E>
                         standard is appropriate from a health perspective and for communication purposes. The Administrator has judged the primary annual standard (in conjunction with the other primary standards) as revised in this final action to be requisite to protect public health with an adequate margin of safety, based on the health evidence discussed in section II.A.2. Setting the 50 breakpoint lower than the annual standard also has the potential to cause confusion with the public since it does not reflect the standards and the Administrator's judgments about the standards as well.

                    <P>
                        With regard to the 100 breakpoint of the AQI, several commenters expressed the view that the level of the 24-hour PM
                        <E T="52">2.5</E>
                         standard and an AQI value of 100 should be set at 25 μg/m
                        <SU>3</SU>
                         based on the body of evidence and lower end of the range recommended by CASAC. These commenters noted that if the current 24-hour standard and AQI value of 100 is retained at 35 μg/m
                        <SU>3</SU>
                         then the public will not be able to make informed decisions about actions to take to protect their health. Many of these commenters further recommended that the AQI value of 100 should be lowered to 25 μg/m
                        <SU>3</SU>
                         even if the standard is retained. Commenters expressed the view that this would more adequately allow the public to take health-protective actions.
                    </P>
                    <P>
                        The EPA disagrees with these commenters and notes that many State, Tribal and local air agencies have expressed strong support for aligning the 100 breakpoint of the AQI with the short-term 24-hour primary PM
                        <E T="52">2.5</E>
                         standards as discussed in the proposal (88 FR 5558, January 27, 2023). The EPA agrees with the view, expressed by State, local and Tribal entities, that aligning the lower breakpoints with the standards enables clear communication of the standards. This alignment approach is also utilized in the other AQI sub-indices lower breakpoints and taking a different approach with the PM
                        <E T="52">2.5</E>
                         AQI could cause confusion. Additionally, the Administrator has judged that it is appropriate to retain the 24-hour standard at a level of 35 μg/m
                        <SU>3</SU>
                         (in conjunction with the other primary standards) to protect public health with an adequate margin of safety, based on the health evidence discussed in section II.A.2. Thus, EPA disagrees that it is necessary or appropriate to set the 100 breakpoint at a lower concentration to provide further information to the public. The 50 breakpoint, which is set at a level below 25 μg/m
                        <SU>3</SU>
                        , will continue to provide information to members of the public particularly concerned about exposures to PM
                        <E T="52">2.5</E>
                        . As with the 50 breakpoint, aligning the breakpoint with the standard both reflects the Administrator's judgment about the health risks and eliminates the potential to cause confusion in the public about those risks.

                        Some commenters supported the proposed revisions to the 200, 300 and 500 breakpoints that recognize the expanded body of scientific evidence, particularly several new epidemiologic studies conducted during high pollution events such as wildfires and multiple controlled human exposure studies. A few commenters agreed with incorporating the expanded body of scientific evidence into the 200, 300 and 500 breakpoints, but suggested a modified linear approach between 200 (115 μg/m
                        <SU>3</SU>

                        ) based on recent epidemiologic wildfire smoke studies.

                    <P>Other commenters disagreed with the proposed revisions and suggested the EPA should continue using the previous breakpoints that follow the 1999 linear approach (64 FR 42530, August 4, 1999), because not changing the breakpoints would simplify communications. A few commenters stated the proposed revisions to the AQI upper breakpoints are not justified because the scientific evidence supporting the revisions is inadequate. To support this view, the commenters suggest that only three epidemiologic studies were used in determining the upper breakpoints and none of them were representative of potential effects in the general public; of the 13 studies cited only three were near the proposed revised breakpoints; four of the studies involved exposure to PM from diesel and traffic pollution, which is different than PM from wildfire smoke; and the data supporting the revisions only indicated “mild” health effects that were mostly in sensitive populations.</P>

                        The EPA agrees with the majority of commenters that supported utilizing the expanded body of scientific evidence to revise the 200, 300 and 500 breakpoints of the AQI. The EPA appreciates the suggestion of using a revised linear approach from 200 to 500. But rather than using the available evidence to only set the breakpoint of 500, the EPA finds it appropriate to set the breakpoints for 200, 300 and 500 using an evidence-based approach, by relying on information presented in both controlled human exposure studies and epidemiologic studies that examine relationships between high PM
                        <E T="52">2.5</E>
                         exposure episodes (
                        <E T="03">i.e.,</E>
                         periods of wildfire smoke) and various health outcomes. Setting these breakpoints based directly on health effects evidence, which can be communicated, is more useful and appropriate than using a linear approach, because it can better describe the potential health effects and symptoms which also helps the public better understand why more health protective actions are needed. By its nature, a linear approach does not evaluate and identify associated health effects and risk factors.
                    </P>
                    <P>
                        The EPA disagrees with the commenters that expressed the view that these upper breakpoints should not be revised based largely on the numerous peer-reviewed studies published since the 200, 300 and 500 breakpoints were originally established in 1999 (64 FR 42530, August 4, 1999). As discussed in the proposal (88 FR 5641, January 27, 2023), the rationale behind the proposed revisions is rooted in the fact the upper AQI breakpoints are based on outdated scientific evidence. Specifically, the traditional linear approach was predicated on the 500 value of the AQI, which was estimated using health studies that used the British Smoke Method. The British Smoke Method is based on a particle size fraction (4.5 microns) that is larger 
                        <PRTPAGE P="16308"/>
                        than PM
                        <E T="52">2.5</E>
                        . Given that the British Smoke method has a larger particle size cutpoint than the current PM
                        <E T="52">2.5</E>
                         monitoring method, which has a cutpoint of 2.5 microns, a concentration of 500 μg/m
                        <SU>3</SU>
                         based on the British Smoke method would be equivalent to a lower PM
                        <E T="52">2.5</E>
                         concentration (88 FR 5641, January 27, 2023). The combination of a larger particle size fraction informing previous decisions around upper AQI breakpoints and more recent scientific evidence than the London Fog Episode, on the potential health consequences of what we currently consider to be high PM
                        <E T="52">2.5</E>
                         exposures, provides the underlying basis for revising the upper breakpoints to better inform the public about air quality to allow the public to take health protective actions as appropriate. Moreover, as discussed above, until recently there was limited information upon which to base the breakpoints between 150 and 500, so the linear approach was a reasonable substitute. While not changing the breakpoints may be easier because there is no change to communicate, using a health-based approach is more appropriate, because it helps the public better understand that more health protective actions are needed.

                    <P>
                        The Agency disagrees that the scientific evidence discussed in the proposal is inadequate to revise the 200, 300 and 500 breakpoints of the AQI (88 FR 5640, January 27, 2023). The EPA disagrees that these studies should not be considered because they “indicated mild health effects in sensitive populations.” The EPA notes that many of the subclinical effects discussed in the proposal (88 FR 5640, January 27, 2023) that informed the breakpoints are on the biologically plausible pathway (see 2019 ISA, section 6.1.1 and Figure 6-1) to more severe cardiovascular outcomes, such as ED visits, hospital admissions, and death as depicted in the large number of epidemiologic studies evaluated in the 2019 ISA and ISA Supplement. From a public health perspective, the purpose of the AQI is to inform the public when air quality could adversely affect their health. The scientific evidence informed revisions to the breakpoints at the upper end of the AQI allow it to better reflect the risk of experiencing health effects at higher PM
                        <E T="52">2.5</E>
                         concentrations. In addition, the EPA disagrees with the commenter that the effects reported at these higher concentrations were observed only in sensitive populations as these effects were also reported in healthy populations (Ghio et al., 2000; Ghio et al., 2003; Urch et al., 2010; Ramanathan et al., 2016; Sivagangabalan et al., 2011; Brook et al., 2009; Bellavia et al.

                        The EPA received a few additional comments on elements of the PM
                        <E T="52">2.5</E>
                         AQI, including the averaging time. Some commenters expressed the view that the 24-hour averaging time was not useful when informing the public how to protect their health, particularly during rapidly changing conditions such as wildfire smoke events. Instead, they suggested a subdaily averaging time of 1-3 hours would be more effective because it more closely aligns with how people breathe.

                    <P>
                        A few of these commenters suggested that instead of changing the AQI averaging time, which aligns with the short-term standard, the EPA could create a public health warning system for unhealthy PM
                        <E T="52">2.5</E>
                         levels. The commenters noted that aligning the AQI averaging time with the short-term standard could be useful for consistent communication with the standards and attainment but suggested that a subdaily warning system could better allow the public to take health protective actions.
                    </P>
                    <P>
                        The EPA disagrees that a shorter averaging period for the PM
                        <E T="52">2.5</E>
                         AQI sub-index would be better. The health effects evidence supporting a subdaily metric is limited and inconsistent. As part of its review of the health effects evidence, the 2019 ISA evaluated whether a subdaily metric would be more closely related to health effects. Most epidemiologic studies that examined the relationship between short-term PM
                        <E T="52">2.5</E>
                         exposures and health effects evaluated an exposure metric averaged over 24-hours. Some recent studies, focusing on respiratory and cardiovascular effects and mortality, have examined whether there is evidence that subdaily exposure metrics are more closely related to health effects than a traditional 24-hour average metric. After evaluating this limited newer evidence, the 2019 ISA concluded that “collectively, the available evidence does not indicate that subdaily averaging periods for PM
                        <E T="52">2.5</E>
                         are more closely associated with health effects than the 24-hour avg exposure metric,” (2019 ISA, chapter 1, section 1.5.2.1, pp. 146-147; U.S. EPA, 2022a).
                    </P>
                    <P>
                        In addition, there are communication benefits to aligning the averaging time of the AQI with the daily standard, as some of these commenters note, such as providing consistent messages about when it may be beneficial for people to take actions to reduce PM
                        <E T="52">2.5</E>
                         exposures. Furthermore, with regard to an additional warning system, the EPA is concerned that having two air quality communication systems operating at the same time would likely be confusing to the public and reduce the effectiveness of the systems.
                    </P>
                    <P>
                        At the same time, the EPA recognizes that when air quality is rapidly changing, such as during wildfire smoke events, reporting information based on a 24-hour metric may not be as useful for the public as reporting more frequently would be. The EPA has balanced concerns about being able to provide timely communication of air quality hazards when conditions are changing quickly with the goal of limiting the number of air quality communications systems and its judgment that the evidence supports a 24-hour-based metric linked to the daily standard by establishing the NowCast, which takes into consideration subdaily PM
                        <E T="52">2.5</E>
                         concentrations and provides a near real-time AQI value based on the AQI colors and scale. Specifically, the NowCast shows air quality conditions for the most current hour of PM
                        <E T="52">2.5</E>
                         data available by using a calculation that involves multiple hours of past data. As noted in the AQI Technical Assistance Document, the NowCast currently uses longer averages during periods of stable air quality and shorter averages (down to a 3-hour average) when air quality is changing rapidly, such as during a wildfire (U.S. EPA, 2018a). As discussed further in section IV.D.2 of this notice, the EPA uses the NowCast to approximate the complete daily AQI (24-hour average) during any given hour. This means the subdaily NowCast is approximating a 24-hour average exposure, which aligns with the health evidence and the existing AQI communications network, while also being capable of communicating rapidly changing conditions to the public.

                    <P>Upon reviewing and considering the comments on the proposed revisions (summarized above in Section IV.C) along with the scientific evidence outlined in the proposal (88 FR 5639, January 27, 2023) and summarized above in section IV.A, the EPA is finalizing the proposed changes to the AQI.</P>

                    <HD SOURCE="HD2">D. Air Quality Index Reporting</HD>
                    <P>With respect to the reporting requirements for the AQI and as noted in the proposal (88 FR 5642, January 27, 2023) there have been many technological advances in air quality monitoring and data reporting since the appendix G to 40 CFR part 58 was last revised in 1999. Federal, State, local, and Tribal agencies have used these changes to make health information and air quality data more readily available and easier to access. Given this, it is useful to update the reporting requirements and recommendations to match current practices and ensure the public has the most useful and timely information to take health-protective behaviors.</P>
                    <HD SOURCE="HD3">1. Summary of Proposed Revisions</HD>
                    <P>Currently, appendix G defines daily reporting as five days per week. When this reporting requirement was originated in 1999 the technology available at that time was not sufficient to calculate and report the AQI more than five days per week without requiring additional staffing on the weekends. Since that time, advances in technology have allowed for reporting seven days per week automatically without expending additional resources on weekends. As a result, most State, local, and Tribal air agencies now report the AQI seven days per a week. Given these technological advances and noting that reporting agencies currently report the AQI seven days per week, the EPA proposed that State, local, and Tribal agencies that report the AQI be required to report it seven days a week, ensuring that the members of the public continue to have access to daily air quality and health information that they can use to take steps to protect their health.</P>
                    <P>Improvements in monitoring networks and modeling capabilities have also enabled the ability to report the AQI in near real-time. This allows State, local, and Tribal air agencies to provide timely air quality information to the public for making health-protective decisions and to help satisfy AQI reporting requirements. The availability of near real-time AQI data also allows for more timely responses by the public when air quality conditions are changing rapidly, such as during wildfire smoke events. Subdaily reporting of the AQI can be critical when there are rapidly change conditions and/or high pollution events so that the public is able to make informed decisions to protect their health. Many State, local, and Tribal air agencies currently report the AQI hourly to ensure that the public has access to accurate and timely information. In recognition of these advances, and to continue to provide for near-real time AQI reporting that the public has come to rely on, the EPA proposed to recommend that State, local, and Tribal agencies report the AQI in near-real time.</P>
                    <P>In lieu of or along with reporting the near-real-time AQI directly to the public, most State/local and Tribal agencies submit hourly air quality data to the EPA. The EPA and some State, local and Tribal air quality agencies use this near-real-time data to create products for use by the public, weather service providers and the media as discussed in the proposal (88 FR 5643, January 27, 2023). To continue to ensure the availability of the products that the public and many stakeholders rely upon, the EPA proposed to recommend that State, local, and Tribal air quality agencies submit hourly data to the EPA's air quality database. Submitting hourly data to the EPA for use on the AirNow website and in other products also enables State, local, and Tribal air quality agencies to meet the recommendation to report the AQI in near-real-time.</P>
                    <P>In addition to the proposed updates to the reporting requirements and recommendations for near-real-time reporting and data submission recommendations, the Agency also proposed reformatting the question-and-answer format used in appendix G to align with the current standard formatting used in the Code of Federal Regulations. In proposing to update the format, the EPA did not reopen the language that has merely been moved or rearranged as there are no substantive changes.</P>
                    <P>
                        Another change the EPA proposed to make to appendix G is with regard to Table 2—Breakpoints for the AQI for purposes of clarity. As discussed in the proposal (88 FR 5642, January 27, 2023) and summarized here, the EPA proposed to collapse the two rows presented for the Hazardous Category into one. The two rows in the current table specify pollutant concentrations for two AQI ranges within the Hazardous category (301-400 and 401-500), with an intermediate break at 400. The 400 breakpoint for all criteria pollutants in the current Table 2 is set at the proportional pollutant concentration approximately halfway between the Index values of 300 and 500. In proposing updated AQI breakpoints for PM
                        <E T="52">2.5</E>
                        , the EPA considered adjusting the 400 breakpoint similarly. However, the EPA concluded that collapsing the two rows into a single range (301-500) would provide a more transparent and easy-to-follow presentation of the pollutant concentrations corresponding to the AQI range for the Hazardous category. Moreover, collapsing the Hazardous category into a single row in Table 2 has no substantive effect on the Emergency Episode program in 40 CFR part 51, appendix L. Thus, the EPA proposed to remove the breakpoint of 400 from the table in appendix G but this change would not substantively affect the derivation of the AQI for any pollutant.
                    </P>
                    <P>
                        In addition, the EPA proposed to move some information currently in appendix G into the Technical Assistance Document for the Reporting of Daily Air Quality, or TAD (U.S. EPA, 2018a), so that it can be updated in a more timely manner to reflect current scientific and health effects evidence and current communication methods, thereby assisting State, local, and Tribal agencies in providing accurate and timely information to the public. Information that was proposed to be moved from appendix G to the TAD included the definitions of the sensitive (at-risk) populations for each pollutant. 
                        <PRTPAGE P="16310"/>
                        This definition is typically evaluated and updated, as warranted, in most NAAQS reviews, even if the standard is not revised. Generally, if the standard is not revised in a review of the NAAQS, then appendix G is also not revised. Moving the definitions of sensitive groups to the TAD allows them to be updated even when a NAAQS is not revised to be consistent with the definitions of the sensitive (at-risk) populations identified in the ISA for that NAAQS review. Also, the proposal (88 FR 5642, January 27, 2023) recognized that the ways that air quality and health information is supplied to the news media and public changes regularly and thus proposed that information about suggested approaches for public communication be taken out of appendix G and discussed in the TAD.

                    <HD SOURCE="HD3">2. Summary of Significant Comments on the Proposed Revisions</HD>
                    <P>The EPA received many comments on the proposed changes to AQI reporting, many of which supported the proposed revisions. EPA discusses several of the topics that received the most attention from commenters below. Discussion of other comments received on the proposed changes to the AQI can be found in section IV of the Responses to Significant Comments on the 2023 Proposed Reconsideration of the National Ambient Air Quality Standards for Particulate Matter.</P>
                    <P>Most commenters expressed support for revising the definition of “daily reporting” from five days a week to seven days a week. A commenter did not support this change and recommended the EPA maintain the definition of daily as five days per week, noting that State and local air agencies do not routinely work seven days per week and would not be available to perform quality control of this data and report it reliably on weekends.</P>
                    <P>The EPA appreciates the support for this proposed revision and disagrees that the proposed change would require personnel to perform quality control of AQI data on weekends. 40 CFR part 58 Appendix D defines continuous monitoring requirements for agencies participating in the State/Local Air Monitoring Stations (SLAMS) network, and Appendix G states that agencies “  . . . must use concentration data from State/Local Air Monitoring Stations (SLAMS) required by 40 CFR 58.10” when reporting the AQI. Therefore, as noted in Appendix D and G, Agencies are required to report the AQI using monitors within SLAMS, which are not subject to daily quality control/validation.</P>
                    <P>
                        A few commenters noted that the proposal preamble language mentioned AQI is reported three ways (88 FR 5637, 5638, January 27, 2023): “The AQI is reported three ways all of which are useful and complementary. The daily AQI is reported for the previous day and used to observe trends in community air quality, the AQI forecast helps people plan their outdoor activities for the next day, and the near-real-time AQI, or NowCast AQI, tells people whether it is a good time for outdoor activity.” These commenters suggested that the NowCast is being codified in 40 CFR part 58 Appendix G as a method of calculating the AQI, which they oppose, saying that codifying its use is inappropriate given the shortest averaging period of the PM
                        <E T="52">2.5</E>
                         NAAQS remains at 24-hours. Some stated that NowCast values have no direct correlation to the AQI calculation methodology codified in 40 CFR part 58 Appendix G. These commenters say that codifying the NowCast would impose a significant burden on States' forecasting staff.
                    </P>
                    <P>However, some other commenters noted they appreciate the public-friendly format and near real-time data the NowCast provides and use it in their clinical encounters with patients. One air agency recognized the importance of the NowCast near real-time AQI during high pollution events and suggested the EPA should provide more “concrete” health messaging for these short-term spikes.</P>
                    <P>The EPA disagrees that the preamble language proposed to codify the NowCast or to impose a burden on reporting agencies. The preamble to the proposed rule references the AQI being reported in three ways and it does so because the EPA and many State, local and Tribal air quality agencies already report it these three ways. However, text included in the preamble is generally explanatory and does not alter regulatory provisions. Comments that State that EPA is codifying the NowCast into Appendix G are incorrect. Further, in proposed revisions to 40 CFR part 58 Appendix G, the EPA recommended, but did not propose to require, the use of air quality forecasts and a subdaily AQI. Consistent with the proposal, the EPA is therefore not finalizing any additional requirement or burden on States' forecasting staff relative to forecasts or a subdaily AQI.</P>
                    <P>The EPA disagrees with the comment that the NowCast values have no direct correlation to the AQI calculation methodology codified in 40 CFR part 58 Appendix G. As noted in the AQI Technical Assistance Document (Technical Assistance Document for the Reporting of Daily Air Quality—the Air Quality Index (AQI)), the NowCast algorithm is based on the AQI methodology but provides more real-time information to the public (U.S. EPA, 2018a). While the NowCast algorithm is approximating a 24-hour average exposure, it can reflect concentrations observed over shorter averaging times when air quality is changing rapidly (U.S. EPA, 2018a). The EPA reflects the nature of the NowCast in the health messaging provided there.</P>
                    <P>
                        As noted in the above discussion of the AQI, air quality can change quickly during the day. A central purpose of the AQI is to help the public know when it is prudent to take action to reduce their exposure to pollution. Accordingly, the EPA developed the NowCast to estimate the 24-hour AQI for the current hour to give people information and tools to reduce their exposures to protect their health, particularly when air quality may be changing. The NowCast gives people the knowledge and ability to take timely action. They can use this information to reduce their exposure—reducing exposures if PM

                         is high only during a few hours a day will help reduce a person's 24-hour exposure—or be active when air quality is better.

                        The first NowCast method was developed in 2003 and was designed so “current conditions” represent the 24-hour PM

                         standard as closely as possible. This method proved to be slow to respond during rapid air quality changes. In 2013, the EPA developed an updated NowCast method for PM

                         that responds more quickly to rapidly changing air quality conditions, such as those we see during wildfires, to make air quality alerts more timely. We analyzed millions of data points in developing this NowCast method and presented this information to State, local and Tribal air agencies. The updated NowCast, which is still in use, was launched August 1, 2013, on AirNow.gov. It was designed to represent a shorter average (target 3-hour) when air quality is changing rapidly, in part because 3-hour averages from some continuous monitors are more stable than 1-hour averages. The NowCast reflects a longer-term (12-hour) average when air quality is stable.

                        After evaluating the 2013 NowCast method, the EPA concluded that it matched the desired characteristics. The NowCast method responds to rapid changes in air quality yet still reflects a

                        longer-term average when air quality is stable; will work in any location with adequate air quality data and for any air quality situation; gives people the best possible estimate of a 24-hour exposure; allows the EPA to caution people in time for them to take protective action and reduce their 24-hour exposure; and ensures that AQI maps on AirNow more closely match what people see.
                    </P>
                    <P>The AQI is designed to allow people to reduce their exposure when pollution levels are higher and be active outdoors when pollution levels are lower. Since air quality almost always changes during the day, that level of granularity is not possible with a 24-hour forecast. If the public has only the 24-hour forecast, they may miss the times to be active outdoors when air quality is better and may be active outdoors when air quality is worse.</P>
                    <P>Also as noted above, many entities appreciate the near real-time reporting of the AQI that the NowCast provides and suggested more specific messaging is needed. The EPA appreciates this insight and will continue to consider ways to communicate air quality information most effectively to the public. For example, in light of recent wildfire events, the EPA worked with the USFS to pilot the AirNow Fire and Smoke Map.</P>

Thus, as discussed in section IV of the preamble to the proposed rule, the EPA is taking final action to require the AQI be reported seven days a week; recommend that State, local, and Tribal agencies report the AQI in near-real time; recommend that State, local, and Tribal air quality agencies submit hourly data to the EPA's air quality database; reformat appendix G to align with the current standard formatting used in the Code of Federal Regulations; collapse the two rows in Table 2 presented for the Hazardous Category into one by removing the 400 breakpoint; and move some information currently in appendix G into the Technical Assistance Document for the Reporting of Daily Air Quality, or TAD (U.S. EPA, 2018a) such as including the definitions of the sensitive (at-risk) populations for each pollutant and suggested approaches for public communication as stated in the revised Appendix G.</P>

                        This section presents the rationale for the Administrator's decision that no change to the current secondary PM standards is required at this time to provide requisite protection against the public welfare effects of PM within the scope of this reconsideration (
                        <E T="03">i.e.,</E>
                         visibility, climate, and materials effects).
                        <SU>142</SU>
                        <FTREF/>
                         This decision is based on a thorough review of the scientific evidence generally published through December 2017,
                        <SU>143</SU>
                        <FTREF/>
                         as presented in the 2019 ISA (U.S. EPA, 2019a), on the non-ecological public welfare effects of PM pertaining to the presence of PM in ambient air, specifically visibility, climate, and materials effects. Additionally, this decision is based on a thorough evaluation of some studies that became available after the literature cutoff date of the 2019 ISA that could either further inform the adequacy of the current PM NAAQS or address key scientific topics that have evolved since the literature cutoff date for the 2019 ISA, generally through March 2021, as presented in the ISA Supplement 
                        <SU>144</SU>

                         (U.S. EPA, 2022a). The selection of welfare effects evaluated within the ISA Supplement was based on the causality determinations reported in the 2019 ISA and the subsequent use of scientific evidence in the 2020 PA.

                        Specifically, for welfare effects, the focus within the ISA Supplement is on visibility effects. The ISA Supplement does not include an evaluation of studies on climate or materials effects. The Administrator's decision also takes into account the 2022 PA evaluation of the policy-relevant information in the 2019 ISA and ISA Supplement and presentation of quantitative analysis of air quality related to visibility impairment; CASAC advice and recommendations, as reflected in discussions of the drafts of the ISA Supplement and 2022 PA at public meetings and in the CASAC's letters to the Administrator; and public comments received on the proposal.

                             Consistent with the 2016 Integrated Review Plan (U.S. EPA, 2016), other welfare effects of PM, including ecological effects, are being considered in the separate, on-going review of the secondary NAAQS for oxides of nitrogen, oxides of sulfur and PM. Accordingly, the public welfare protection provided by the secondary PM standards against ecological effects such as those related to deposition of nitrogen- and sulfur-containing compounds in vulnerable ecosystems is being considered in that separate review. Thus, the Administrator's decision in this reconsideration will be focused only and specifically on the adequacy of public welfare protection provided by the secondary PM standards from effects related to visibility, climate, and materials and hereafter “welfare effects” refers to non-ecological welfare effects (

While the 2020 PM PA considered the broader set of evidence for these effects, for climate effects and material effects, it concluded that there remained `substantial uncertainties with regard to the quantitative relationships with PM concentrations and concentration patterns that limit[ed] [the] ability to quantitatively assess the public welfare protection provided by the standards from these effects (U.S. EPA, 2020b). Given these uncertainties and limitations, the basis of the discussion on conclusions regarding the secondary standards in the 2020 PM PA primarily focused on visibility effects. Therefore, this Supplement focuses only on visibility effects in evaluating newly available scientific information and is limited to studies

Section V.B summarizes the CASAC's advice (section V.B.1) and the proposed conclusions (section V.B.2), addresses public comments received on the proposal (section V.B.3), and presents the Administrator's conclusions on the adequacy of the current standards (section V.B.4), drawing on consideration of the available scientific and quantitative information, advice from the CASAC, and comments from the public. Section V.C summarizes the Administrator's decision on the secondary PM standards.</P>
                    <HD SOURCE="HD2">A. Introduction</HD>
                    <P>The general approach for this reconsideration of the 2020 final decision on the secondary PM standards relies on the EPA's assessments of the current scientific evidence and associated quantitative analyses to inform the Administrator's judgments regarding secondary standards that are requisite to protect the public welfare from known or anticipated adverse effects associated with the pollutant's presence in the ambient air. The EPA's assessments are primarily documented in the 2019 ISA, ISA Supplement, and 2022 PA, which builds on the 2020 PA, all of which have received CASAC review and public comment (83 FR 53471, October 23, 2018; 83 FR 55529, November 6, 2018; 85 FR 4655, January 27, 2020; 86 FR 52673, September 22, 2021; 86 FR 54186, September 30, 2021; 86 FR 56263, October 8, 2021; 87 FR 958, January 7, 2022; 87 FR 22207, April 14, 2022; 87 FR 31965, May 26, 2022). In bridging the gap between the scientific assessments of the 2019 ISA and ISA Supplement and the judgments required of the Administrator in determining whether the current standards provide the requisite public welfare protection, the 2022 PA evaluates policy implications of the evaluation of the current evidence in the 2019 ISA and ISA Supplement, and the quantitative information documented in the 2022 PA. In evaluating the public welfare protection afforded by the current standards against PM-related effects within the scope of this reconsideration, the four basic elements of the NAAQS (indicator, averaging time, level, and form) are considered collectively.</P>
                    <P>The final decision on the adequacy of the current secondary standards is a public welfare policy judgment to be made by the Administrator. In reaching conclusions with regard to the standard, the decision draws on the scientific information and analyses about welfare effects, and associated public welfare significance, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the scientific evidence and analyses. This approach is based on the recognition that the available evidence generally reflects a continuum that includes ambient air exposures at which scientists agree that effects are likely to occur through lower levels at which the likelihood and magnitude of responses become increasingly uncertain. This approach is consistent with the requirements of the provisions of the Clean Air Act related to the review of NAAQS and with how the EPA and the courts have historically interpreted the Act. These provisions require the Administrator to establish secondary standards that, in the judgment of the Administrator, are requisite to protect public welfare from known or anticipated adverse effects associated with the presence of the pollutant in the ambient air. In so doing, the Administrator seeks to establish standards that are neither more nor less stringent than necessary for this purpose. The Act does not require that standards be set at a zero-risk level, but rather at a level that reduces risk sufficiently so as to protect the public welfare from known or anticipated adverse effects.</P>

                        The current secondary PM standards were retained in 2020 based on the scientific and technical information available at that time, as well as the then-Administrator's judgments regarding the available welfare effects evidence, the appropriate degree of public welfare protection for the existing standards, and available air quality information on visibility impairment that may be allowed by such a standard (85 FR 82684, December 18, 2020).

                    <HD SOURCE="HD3">a. Non-Visibility Effects</HD>
                    <P>In light of the robust evidence base, the 2019 ISA concluded there to be causal relationships between PM and climate effects and materials effects (U.S. EPA, 2019a, sections 13.3.9 and 13.4.2). The 2020 final decision was based on a thorough review in the 2019 ISA of the scientific information on PM-induced climate and materials effects. The decision also took into account: (1) Assessments in the 2020 PA of the most policy-relevant information in the 2019 ISA regarding evidence of adverse effects of PM to climate and materials, (2) uncertainties in the available evidence to inform a quantitative assessment of PM-related climate and materials effects, (3) CASAC advice and recommendations, and (4) public comments received during the development of these documents and on the proposal document.</P>
                    <P>In considering non-visibility welfare effects in the 2020 decision, the then-Administrator concluded that, while it is important to maintain an appropriate degree of control of fine and coarse particles to address non-visibility welfare effects, “it is generally appropriate to retain the existing standards and that there is insufficient information to establish any distinct secondary PM standards to address climate and materials effects of PM” (85 FR 82744, December 18, 2020).</P>
                    <P>
                        With regard to climate, the then-Administrator recognized that there were a number of improvements and refinements to climate models since the 2012 review. However, while the evidence continued to support a causal relationship between PM and climate effects, the then-Administrator noted that significant limitations continued to exist related to quantifying the contributions of direct and indirect 
                        <PRTPAGE P="16313"/>
                        effects of PM and PM components on climate forcing (U.S. EPA, 2020b, sections 5.2.2.1.1 and 5.4). He also recognized that the models continued to exhibit considerable variability in estimates of PM-related climate impacts at regional scales (
                        <E T="03">e.g.,</E>
                         ~100 km) as compared to simulations at global scales. Therefore, the resulting uncertainty led the then-Administrator to conclude in the 2020 decision that the available scientific information remained insufficient to quantify climate impacts associated with particular concentrations of PM in ambient air (U.S. EPA, 2020b, section 5.2.2.2.1) or to evaluate or consider a level of PM air quality in the U.S. to protect against climate effects and that there was insufficient information available to base a national ambient standard on climate impacts (85 FR 82744, December 18, 2020).
                    </P>
                    <P>With regard to materials effects, the then-Administrator noted that the evidence available in the 2019 ISA continued to support a causal relationship between materials effects and PM deposition (U.S. EPA, 2019a, section 13.4). He recognized that the deposition of fine and coarse particles to materials can lead to physical damage and/or impaired aesthetic qualities. Particles can contribute to materials damage by adding to the natural weathering processes and by promoting the corrosion of metals, the degradation of building materials, and the weakening of material components. While some new information was available in the 2019 ISA, the information was from studies primarily conducted outside of the U.S. in areas where PM concentrations in ambient air are higher than those observed in the U.S. (U.S. EPA, 2020b, section 13.4). Additionally, the information assessed in the 2019 ISA did not support quantitative analyses of PM-related materials effects in the 2020 PA (U.S. EPA, 2020b, section 5.2.2.2.2). Given the limited amount of information available and its inherent uncertainties and limitations, the Administrator concluded that he was unable to relate soiling or damage to specific levels of PM in ambient air or to evaluate or consider a level of air quality to protect against such materials effects, and that there was insufficient information available to support a distinct national ambient standard based on materials effects (85 FR 82744, December 18, 2020).</P>
                    <P>
                        In reviewing the 2019 draft PA, the CASAC agreed with staff conclusions that, while these effects are important, “the available evidence does not call into question the protection afforded by the current secondary PM standards” and recommended that the secondary standards “should be retained” (Cox, 2019b, p. 3 of letter). In reaching a final decision in 2020, for all of the reasons discussed above and recognizing the CASAC conclusion that the evidence provided support for retaining the current secondary PM standards, the then-Administrator concluded that it was appropriate to retain the existing secondary PM standards, without revision. For climate and materials effects, this conclusion reflected his judgment that, although it remains important to maintain secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards to provide some degree of control over long- and short-term concentrations of both fine and coarse particles, there was insufficient information to establish distinct secondary PM standards to address non-visibility PM-related welfare effects (85 FR 82744, December 18, 2020).

                        The 2019 ISA concluded that, “the evidence is sufficient to conclude that a causal relationship exists between PM and visibility impairment” (U.S. EPA, 2019a, section 13.2.6). The 2020 decision on the adequacy of the secondary standards with regard to visibility effects was a public welfare policy judgment made by the then-Administrator, which drew upon the available scientific evidence for PM-related visibility effects and on analyses of visibility impairment, as well as judgments about the appropriate weight to place on the range of uncertainties inherent in the evidence and analyses. The 2020 final decision was based on a thorough review in the 2019 ISA of the scientific information on PM-related visibility effects. The decision also took into account: (1) Assessments in the 2020 PA of the most policy-relevant information in the 2019 ISA regarding evidence of adverse effects of PM on visibility; (2) air quality analyses of the PM

                        In considering the visibility effects in the 2020 review, the then-Administrator noted the long-standing body of evidence for PM-related visibility impairment. This evidence, which is based on the fundamental relationship between light extinction and PM mass, demonstrated that ambient PM can impair visibility in both urban and remote areas, and had changed very little since the 2012 review (U.S. EPA, 2019a, section 13.1; U.S. EPA, 2009a, section 9.2.5). The evidence related to public perception of visibility impairment was from studies from four areas in North America.
                        <SU>146</SU>
                        <FTREF/>
                         These studies provided information to inform our understanding of levels of visibility impairment that the public judged to be “acceptable” (U.S. EPA, 2010b; 85 FR 24131, April 30, 2020). In considering these public preference studies, the then-Administrator noted that no new visibility studies conducted in the U.S. were discussed in the 2019 ISA, and there was little newly available information with regard to acceptable levels of visibility impairment in the U.S. The Administrator recognized that visibility impairment can have implications for people's enjoyment of daily activities and their overall well-being, and therefore, considered the degree to which the current secondary standards protect against PM-related visibility impairment.

                             Preference studies were available in four urban areas. Three western preference studies were available, including one in Denver, Colorado (Ely et al., 1991), one in the lower Fraser River valley near Vancouver, British Columbia, Canada (Pryor, 1996), and one in Phoenix, Arizona (BBC Research &amp; Consulting, 2003). A pilot focus group study was also conducted for Washington, DC (Abt Associates, 2001), and a replicate study with 26 participants was also conducted for Washington, DC (Smith and Howell, 2009). More details about these studies are available in Appendix D of the 2022 PA (U.S. EPA, 2022b).

                        Consistent with the 2012 review, in the 2020 review, the then-Administrator first concluded that a target level of protection for a secondary PM standard is most appropriately defined in terms of a visibility index that directly takes into account the factors (
                        <E T="03">i.e.,</E>
                         species composition and relative humidity) that influence the relationship between PM
                        <E T="52">2.5</E>
                         in ambient air and PM-related visibility impairment. In defining a target level of protection, the then-Administrator considered the specific aspects of such an index, including the appropriate indicator, averaging time, form and level (78 FR 82742-82744, December 18, 2020).
                    </P>
                    <P>
                        First, with regard to indicator, the then-Administrator noted that in the 2012 review, the EPA used an index based on estimates of light extinction by PM
                        <E T="52">2.5</E>
                         components calculated using an adjusted version of the IMPROVE algorithm, which allows the estimation of the light extinction using routinely monitored components of PM
                        <E T="52">2.5</E>
                        , PM
                        <E T="52">10-2.5</E>
                         mass, and estimates of relative humidity. The then-Administrator recognized that, while there have been some revisions to the IMPROVE algorithm since the time of the 2012 
                        <PRTPAGE P="16314"/>
                        review, our fundamental understanding of the relationship between PM in ambient air and light extinction had changed little and the various IMPROVE algorithms appropriately reflected this relationship across the U.S. In the absence of a monitoring network for direct measurement of light extinction, he concluded that a calculated light extinction indicator that utilizes the IMPROVE algorithms continued to provide a reasonable basis for defining a target level of protection against PM-related visibility impairment (78 FR 82742-82744, December 18, 2020).

                    <P>
                        In further defining the characteristics of a visibility index, the then-Administrator next considered the appropriate averaging time, form, and level of the index. Given the available scientific information the review, and in considering the CASAC's advice and public comments, the then-Administrator concluded that, consistent with the decision in the 2012 review, a visibility index with a 24-hour averaging time and a form based on the 3-year average of annual 90th percentile values remained reasonable. With regard to the averaging time and form of such an index, the Administrator noted analyses conducted in the last review that demonstrated relatively strong correlations between 24-hour and subdaily (
                        <E T="03">i.e.,</E>
                         4-hour average) PM
                        <E T="52">2.5</E>
                         light extinction (78 FR 3226, January 15, 2013), indicating that a 24-hour averaging time is an appropriate surrogate for the subdaily time periods of the perception of PM-related visibility impairment and the relevant exposure periods for segments of the viewing public. This decision in the 2020 review also recognized that a 24-hour averaging time may be less influenced by atypical conditions and/or atypical instrument performance (78 FR 3226, January 15, 2013). The then-Administrator recognized that there was no new information to support updated analyses of this nature, and therefore, he believed these analyses continued to provide support for consideration of a 24-hour averaging time for a visibility index in this review. With regard to the statistical form of the index, the Administrator noted that, consistent with the 2012 review: (1) A multi-year percentile form offers greater stability from the occasional effect of interannual meteorological variability (78 FR 3198, January 15, 2013; U.S. EPA, 2011, p. 4-58); (2) a 90th percentile represents the median of the distribution of the 20 percent worst visibility days, which are targeted in Federal Class I areas by the Regional Haze Program; and (3) public preference studies did not provide information to identify a different target than that identified for Federal Class I areas (U.S. EPA, 2011, p. 4-59). Therefore, the then-Administrator judged that a visibility index based on estimates of light extinction, with a 24-hour averaging time and a 90th percentile form, averaged over three years, remained appropriate (78 FR 82742-82744, December 18, 2020).

                    <P>
                        With regard to the level of a visibility index, consistent with the 2012 review, the then-Administrator judged that it was appropriate to establish a target level of protection of 30 deciviews (dv),
                        <E T="51">147 148</E>
                        <FTREF/>
                         reflecting the upper end of the range of visibility impairment judged to be acceptable by at least 50% of study participants in the available public preference studies (78 FR 3226, January 15, 2013). The 2011 PA identified a range of levels from 20 to 30 dv based on the responses in the public preference studies available at that time (U.S. EPA, 2011, section 4.3.4). At the time of the 2012 review, the then-Administrator noted a number of uncertainties and limitations in public preference studies, including the small number of stated preference studies available, the relatively small number of study participants, the extent to which the study participants may not be representative of the broader study area population in some of the studies, and the variations in the specific materials and methods used in each study. In considering the available preference studies in 2012, with their inherent uncertainties and limitations, the then-Administrator concluded that the substantial degree of variability and uncertainty in the public preference studies should be reflected in a target level of protection based on the upper end of the range of candidate protection levels (CPLs).

                    <P>Given that there were no new preference studies in the 2019 ISA, the then-Administrator's judgments in 2020 were based on the same studies, with the same range of levels, available in the 2012 review. The 2020 PA (U.S. EPA, 2020b, section 5.5), discussed a number of limitations and uncertainties associated with these studies. In considering the scientific information, with its uncertainties and limitations, as well as public comments on the level of the target level of protection against visibility impairment, the then-Administrator concluded that it was appropriate to again use a level of 30 dv for the visibility index (78 FR 82742-82744, December 18, 2020).</P>

                        Having concluded that the protection provided by a standard defined in terms of a PM

                         visibility index, with a 24-hour averaging time, and a 90th percentile form, averaged over 3 years, set at a level of 30 dv, was requisite to protect public welfare with regard to visual air quality, the Administrator next considered the degree of protection from visibility impairment afforded by the existing suite of secondary PM standards.

                    <P>
                        In this context, the then-Administrator considered the updated analyses of visibility impairment presented in the 2020 PA (U.S. EPA, 2020b, section 5.2.1.2), which reflected a number of improvements since the 2012 review. Specifically, the updated analyses examined multiple versions of the IMPROVE equation, including the version incorporating revisions since the time of the 2012 review. These updated analyses provided a further understanding of how variation in the inputs to the algorithms affect the estimates of light extinction (U.S. EPA, 2020b, Appendix D). Additionally, for a subset of monitoring sites with available PM
                        <E T="52">10-2.5</E>
                         data, the updated analyses better characterized the influence of coarse PM on light extinction than in the 2012 review (U.S. EPA, 2020b, section 5.2.1.2).
                    </P>
                    <P>
                        The results of the updated analyses in the 2020 PA were consistent with those from the 2012 review. Regardless of which version of the IMPROVE equation was used, the analyses demonstrated that, based on 2015-2017 data, the 3-year visibility metric was at or below about 30 dv in all areas meeting the current 24-hour PM

While the inclusion of the coarse fraction had a relatively modest impact on the estimates of light extinction, the then-Administrator recognized the continued importance of the PM

                         standard given the potential for larger impacts on light extinction in areas with higher coarse particle concentrations, which were not included in the analyses in the 2020 PA due to a lack of available data (U.S. EPA, 2019a, section 13.2.4.1; U.S. EPA, 2020b, section 5.2.1.2).

                    <HD SOURCE="HD3">2. Overview of Welfare Effects Evidence</HD>
                    <P>The information summarized here is based on the scientific assessment of the welfare effects evidence available in this reconsideration; this assessment is documented in the 2019 ISA and ISA Supplement and its policy implications are further discussed in the 2022 PA. While the 2019 ISA provides the broad scientific foundation for this reconsideration, additional literature has become available since the cutoff date of the 2019 ISA that expands the body of evidence related to visibility effects that can inform the Administrator's judgment on the adequacy of the current secondary PM standards. As such, the ISA Supplement builds on the information in the 2019 ISA with a targeted identification and evaluation of new scientific information regarding visibility effects. As described in the ISA Supplement and the 2022 PA, the selection of welfare effects to evaluate within the ISA Supplement were based on the causality determinations reported in the 2019 ISA and the subsequent use of scientific evidence in the 2020 PA (U.S. EPA, 2019a, section 1.2; U.S. EPA, 2022a, section 1.4.2). The ISA Supplement focuses on U.S. and Canadian studies that provide new information on public preferences for visibility impairment and/or developed new methodologies or conducted quantitative analyses of light extinction (U.S. EPA, 2022a, section 1.2). Such studies of visibility effects and quantitative relationships between visibility impairment and PM in ambient air were considered to be of greatest utility in informing the Administrator's conclusions on the adequacy of the current secondary PM standards. The visibility effects evidence presented within the 2019 ISA, along with the targeted identification and evaluation of new scientific information in the ISA Supplement, provides the scientific basis for the reconsideration of the 2020 final decision on the secondary PM standards for visibility effects. For climate and materials effects, the 2020 PA concluded that there were substantial uncertainties associated with the quantitative relationships with PM concentrations and the concentration patterns that limited the ability to quantitatively assess the public welfare protection provided by the standards from these effects. Therefore, the evaluation of the information related to these effects draws heavily from the 2019 ISA and 2020 PA. The subsections below briefly summarize the nature of PM-related visibility (section V.B.1.a), climate (section V.B.1.b), and materials (section V.B.1.c) effects.</P>
                    <HD SOURCE="HD3">a. Nature of Effects</HD>
                    <P>Visibility impairment can have implications for people's enjoyment of daily activities and for their overall sense of well-being (U.S. EPA, 2009a, section 9.2). The strongest evidence for PM-related visibility impairment comes from the fundamental relationship between light extinction and PM mass (U.S. EPA, 2009a), which confirms a well-established “causal relationship exists between PM and visibility impairment” (U.S. EPA, 2009a, p. 2-28). Beyond its effects on visibility, the 2009 ISA also identified a causal relationship “between PM and climate effects, including both direct effects of radiative forcing and indirect effects that involve cloud and feedbacks that influence precipitation formation and cloud lifetimes” (U.S. EPA, 2009a, p. 2-29). The evidence also supports a causal relationship between PM and effects on materials, including soiling effects and materials damage (U.S. EPA, 2009a, p. 2-31).</P>
                    <P>The evidence available in this reconsideration is consistent with the evidence available at the time of the 2012 and 2020 reviews and supports the conclusions of causal relationships between PM and visibility, climate, and materials effects (U.S. EPA, 2019a, chapter 13). Evidence newly available in this reconsideration augments the previously available evidence of the relationship between PM and visibility impairment (U.S. EPA, 2019a, section 13.2; U.S. EPA, 2022a, section 4), climate effects (U.S. EPA, 2019a, section 13.3), and materials effects (U.S. EPA, 2019a, section 13.4).</P>

                        The fundamental relationship between light extinction and PM mass, and the EPA's understanding of this relationship, has changed little since the 2009 ISA (U.S. EPA, 2009a). The combined effect of light scattering and absorption by particles and gases is characterized as light extinction, 
                        <E T="03">i.e.,</E>
                         the fraction of light that is scattered or absorbed per unit of distance in the atmosphere.
                        <SU>149</SU>
                        <FTREF/>
                         Light extinction is measured in units of 1/distance, which is often expressed in the technical literature as visibility per megameter (abbreviated Mm
                        <E T="51">−1</E>
                        ). Higher values of light extinction (usually given in units of Mm
                        <E T="51">−1</E>
                         or dv) correspond to lower visibility. When PM is present in the air, its contribution to light extinction is typically much greater than that of gases (U.S. EPA, 2019a, section 13.2.1). The impact of PM on light scattering depends on particle size and composition, as well as relative humidity. All particles scatter light, as described by the Mie theory, which relates light scattering to particle size, shape, and index of refraction (U.S. EPA, 2019a, section 13.2.3; Mie, 1908, Van de Hulst, 1981). Fine particles scatter more light than coarse particles on a per unit mass basis and include sulfates, nitrates, organics, light-absorbing carbon, and soil (Malm et al., 1994). Hygroscopic particles like ammonium sulfate, ammonium nitrate, and sea salt increase in size as relative humidity increases, leading to increased light scattering (U.S. EPA, 2019a, section 13.2.3).

                             All particles scatter light and, although a larger particle scatters more light than a similarly shaped smaller particle of the same composition, the light scattered per unit of mass is greatest for particles with diameters from ~0.3-1.0 µm (U.S. EPA, 2009a, section 2.5.1; U.S. EPA, 2019a, section 13.2.1). Particles with hygroscopic components (
                            <E T="03">e.g.,</E>
                             particulate sulfate and nitrate) contribute more to light extinction at higher relative humidity than at lower relative humidity because they change size in the atmosphere in response to relative humidity.

                        As at the time of the 2012 and 2020 reviews, direct measurements of PM light extinction, scattering, and absorption continue to be considered more accurate for quantifying visibility than PM mass-based estimates because measurements do not depend on assumptions about particle characteristics (
                        <E T="03">e.g.,</E>
                         size, shape, density, component mixture, etc.) (U.S. EPA, 2019a, section 13.2.2.2). Measurements of light extinction can be made with high time resolution, allowing for characterization of subdaily temporal patterns of visibility impairment. A number of measurement methods have been used for visibility impairment (
                        <E T="03">e.g.,</E>

                        transmissometers, integrating nephelometers, teleradiometers, telephotometers, and photography and photographic modeling), although each of these methods has its own strengths and limitations (U.S. EPA, 2019a, Table 13-1). While some recent research confirms and adds to the body of knowledge regarding direct measurements as is described in the 2019 ISA and ISA Supplement, no major new developments have been made with these measurement methods since prior reviews (U.S. EPA, 2019a, section 13.2.2.2; U.S. EPA, 2022a, section 4.2).
                    </P>
                    <P>
                        In the absence of a robust monitoring network for the routine measurement of light extinction across the U.S., estimation of light extinction based on existing PM monitoring can be used. The theoretical relationship between light extinction and PM characteristics, as derived from Mie theory (U.S. EPA, 2019a, Equation 13.5), can be used to estimate light extinction by combining mass scattering efficiencies of particles with particle concentrations (U.S. EPA, 2019a, section 13.2.3; U.S. EPA, 2009a, sections 9.2.2.2 and 9.2.3.1). This estimation of light extinction is consistent with the method used in previous reviews. The algorithm used to estimate light extinction, known as the IMPROVE algorithm,
                        <SU>150</SU>
                        <FTREF/>
                         provides for the estimation of light extinction (b

                        ), in units of Mm
                        <SU>-1</SU>
                        , using routinely monitored components of fine (PM
                        <E T="52">2.5</E>
                        ) and coarse (PM

                        ) PM. Relative humidity data are also needed to estimate the contribution by liquid water that is in solution with the hygroscopic components of PM. To estimate each component's contribution to light extinction, their concentrations are multiplied by extinction coefficients and are additionally multiplied by a water growth factor that accounts for their expansion with moisture. Both the extinction efficiency coefficients and water growth factors of the IMPROVE algorithm have been developed by a combination of empirical assessment and theoretical calculation using particle size distributions associated with each of the major aerosol components (U.S. EPA, 2019a, sections 13.2.3.1 and 13.2.3.3).

                             The algorithm is referred to as the IMPROVE algorithm as it was developed specifically to use monitoring data generated at IMPROVE network sites and with equipment specifically designed to support the IMPROVE program and was evaluated using IMPROVE optical measurements at the subset of monitoring sites that make those measurements (Malm et al., 1994).

                    <P>At the time of the 2012 review, two versions of the IMPROVE algorithm were available in the literature—the original IMPROVE algorithm (Lowenthal and Kumar, 2004, Malm and Hand, 2007, Ryan et al., 2005) and the revised IMPROVE algorithm (Pitchford et al., 2007). As described in detail in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.1) and the 2019 ISA (U.S. EPA, 2019a, section 13.2.3), the algorithm has been further evaluated and refined since the time of the 2012 review (Lowenthal and Kumar, 2016), particularly for PM characteristics and relative humidity in remote areas. All three versions of the IMPROVE algorithm were considered in evaluating visibility impairment in this reconsideration.</P>

                        Consistent with the evidence available at the time of the 2012 and 2020 reviews, our understanding of public perception of visibility impairment comes from visibility preference studies conducted in four areas in North America.

                         The detailed methodology for these studies are described in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.1), the 2019 ISA (U.S. EPA, 2019a), and the 2009 ISA (U.S. EPA, 2019a). In summary, the study participants were queried regarding multiple images that were either photographs of the same location and scenery that had been taken on different days on which measured extinction data were available or digitized photographs onto which a uniform “haze” had been superimposed. Results of the studies indicated a wide range of judgments on what study participants considered to be acceptable visibility across the different study areas, depending on the setting depicted in each photograph. Based on the results of the four cities, a range encompassing the PM

Much lower visibility (considerably more haze resulting in higher values of light extinction) was considered acceptable in Washington, DC, than was in Denver, and 30 dv reflected the level of impairment that was determined to be “acceptable” by at least 50 percent of study participants (78 FR 3226-3227, January 15, 2013).

                        Since the completion of the 2009 and 2019 ISAs, there has been only one public preference study that has become available in the U.S. This study uses images of the Grand Canyon, AZ, described in the ISA Supplement (U.S. EPA, 2022a). The Grand Canyon study, conducted by Malm et al. (2019), has a similar study design to that used in the public preference studies discussed above; however, there are several important differences that make it difficult to directly compare the results of the Malm et al. (2019) study with other public preference studies. As an initial matter, the Grand Canyon study was conducted in a Federal Class I area, as opposed to in an urban area, with a scene depicted in the photographs that did not include urban features.

                         We recognize that public preferences with respect to visibility in Federal Class 1 areas may well differ from visibility preferences in urban areas and other contexts, although there is currently a lack of information to on such questions. Further, the Malm et al. (2019) study also used a much lower range of superimposed “haze” than the preference studies discussed above.

                         It is unclear whether the participant preferences are a function in part of the range of potential values presented, such that the participant preferences for the Grand Canyon were generally lower

                         than the other preference studies in part because of the lower range of superimposed “haze” for the images in that study, or if their preferences would vary if presented with images with a range of superimposed “haze” more comparable to the levels used in the other studies (
                        <E T="03">i.e.,</E>

The scenes presented in the previously available visibility preference studies are presented in more detail in Table D-9 in the 2022 PA (U.S. EPA, 2022b, Appendix D).

In those studies, the visibility ranges presented were as low as 9 dv and as high as 45 dv. The visibility ranges presented in the previously available visibility preference studies are described in more detail in Table D-9 in the 2022 PA (U.S. EPA, 2022b, Appendix D).

                        The Malm et al. (2019) study also explored alternate methods for evaluating “acceptable” levels of visual air quality from the preference studies, including the use of scene-specific visibility indices as potential indicators of visibility levels as perceived by the observer (Malm et al., 2019). In addition to measures of atmospheric haze, such 
                        <PRTPAGE P="16317"/>
                        as atmospheric extinction, used in previously available preference studies, other indices for visual air quality include color and achromatic contrast of single landscape figures, average and equivalent contrast of an entire scene, edge detection algorithms such as the Sobel index, and just-noticeable difference or change indexes. The results reported by Malm et al. (2019) suggest that scene-dependent metrics, such as contrast, may be useful alternate predictors of preference levels compared to universal metrics like light extinction (U.S. EPA, 2022a, section 4.2.1). This is because extinction alone is not a measure of “haze,” but of light attenuation per unit distance, and visible “haze” is dependent on both light extinction and distance to a landscape feature (U.S. EPA, 2022a, section 4.2.1). However, there are very few studies available that use scene-dependent metrics (

                         contrast) to evaluate public preference information, which makes it difficult to evaluate them as an alternative to the light extinction approach.

                        The available evidence continues to support the conclusion of a causal relationship between PM and climate effects (U.S. EPA, 2019a, section 13.3.9). Since the 2012 review, climate impacts have been extensively studied and recent research reinforces and strengthens the evidence evaluated in the 2009 ISA. Recent evidence provides greater specificity about the details of radiative forcing effects

                        <FTREF/>
                         and increases the understanding of additional climate impacts driven by PM radiative effects. The Intergovernmental Panel on Climate Change (IPCC) assesses the role of anthropogenic activity in past and future climate change, and since the completion of the 2009 ISA, has issued the Fifth IPCC Assessment Report (AR5; IPCC, 2013), which summarizes any key scientific advances in understanding the climate effects of PM since the previous report. As in the 2009 ISA, the 2019 ISA draws substantially on the IPCC report to summarize climate effects. As discussed in more detail in the 2022 PA (U.S. EPA, 2022b, section 5.3.2.1.1), the general conclusions are similar between the IPCC AR4 and AR5 reports with regard to effects of PM on global climate. Consistent with the evidence available in the 2012 review, the key components, including sulfate, nitrate, organic carbon (OC), black carbon (BC), and dust, that contribute to climate processes vary in their reflectivity, forcing efficiencies, and direction of forcing. Since the completion of the 2009 ISA, the evidence base has expanded with respect to the mechanisms of climate responses and feedbacks to PM radiative forcing; however, the recently published literature assessed in the 2019 ISA does not reduce the considerable uncertainties that continue to exist related these mechanisms.

                             Radiative forcing (RF) for a given atmospheric constituent is defined as the perturbation in net radiative flux, at the tropopause (or the top of the atmosphere) caused by that constituent, in watts per square meter (Wm
                            <SU>-2</SU>
                            ), after allowing for temperatures in the stratosphere to adjust to the perturbation but holding all other climate responses constant, including surface and tropospheric temperatures (Fiore et al., 2015; Myhre et al., 2013). A positive forcing indicates net energy trapped in the Earth system and suggests warming of the Earth's surface, whereas a negative forcing indicates net loss of energy and suggests cooling (U.S. EPA, 2019a, section 13.3.2.2).

                        As described in the proposal (88 FR 5650, January 27, 2023), PM has a very heterogeneous distribution globally and patterns of forcing tend to correlate with PM loading, with the greatest forcings centralized over continental regions. The climate response to this PM forcing, however, is more complicated since the perturbation to one climate variable (
                        <E T="03">e.g.,</E>
                         temperature, cloud cover, precipitation) can lead to a cascade of effects on other variables. While the initial PM radiative forcing may be concentrated regionally, the eventual climate response can be much broader spatially or be concentrated in remote regions, and may be quite complex, affecting multiple climate variables with possible differences in the direction of the forcing in different regions or for different variables (U.S. EPA, 2019a, section 13.3.6). The complex climate system interactions lead to variation among climate models, which have suggested a range of factors that can influence large-scale meteorological processes and may affect temperature, including local feedback effects involving soil moisture and cloud cover, changes in the hygroscopicity of the PM, and interactions with clouds (U.S. EPA, 2019a, section 13.3.7). As a result, there remains insufficient evidence to related climate effects to specific PM levels in ambient air or to establish a quantitative relationship between PM and climate effects, particularly at a regional scale. Further research is needed to better characterize the effects of PM on regional climate in the U.S. before PM climate effects can be quantified.

                        Consistent with the evidence assessed in the 2009 ISA, the available evidence continues to support the conclusion that there is a causal relationship between PM deposition and materials effects. Effects of deposited PM, particularly sulfates and nitrates, to materials include both physical damage and impaired aesthetic qualities, generally involving soiling and/or corrosion (U.S. EPA, 2019a, section 13.4.2). Because of their electrolytic, hygroscopic, and acidic properties and their ability to sorb corrosive gases, particles contribute to materials damage by adding to the effects of natural weathering processes, by potentially promoting or accelerating the corrosion of metals, degradation of painted surfaces, deterioration of building materials, and weakening of material components.

                         There is a limited amount of recently available data for consideration in this review from studies primarily conducted outside of the U.S. on buildings and other items of cultural heritage. However, these studies involved concentrations of PM in ambient air greater than those typically observed in the U.S. (U.S. EPA, 2019a, section 13.4).

                        Building on the evidence available in the 2009 ISA, and as described in detail in the proposal (88 FR 5650, January 27, 2023) and in the 2019 ISA (U.S. EPA, 2019a, section 13.4), research has progressed on (1) the theoretical understanding of soiling of items of cultural heritage; (2) the quantification of degradation rates and further characterization of factors that influence damage of stone materials; (3) materials damage from PM components besides sulfate and black carbon and atmospheric gases besides SO

While the evidence of PM-related materials effects has expanded somewhat since the completion of the 2009 ISA, there remains insufficient evidence to relate soiling or damage to specific PM levels in ambient air or to establish a quantitative relationship between PM and materials degradation. The recent evidence assessed in the 2019 ISA is generally similar to the evidence available in the 2009 ISA, including

                    <P>
                        In the 2012 and 2020 reviews, quantitative analyses for PM-related visibility effects focused on daily visibility impairment, given the short-term nature of PM-related visibility effects. The evidence and information available in this reconsideration continues to provide support for the short-term (
                        <E T="03">i.e.,</E>
                         hourly or daily) nature of PM-related visibility impairment. As such, the quantitative analyses presented in the 2022 PA continue to focus on daily visibility impairment and utilize a two-phase assessment approach for visibility impairment, consistent with the approaches taken in past reviews. First, the 2022 PA considers the appropriateness of the elements (indicator, averaging time, form, and level) of the visibility index for providing protection against PM-related visibility effects. Second, recent air quality was used to evaluate the relationship between the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard and the visibility index. The information available since the 2012 review includes an updated equation for estimating light extinction, summarized in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.1) and described in the 2019 ISA (U.S. EPA, 2019a, section 13.2.3.3), as well as more recent air monitoring data, that together allow for development of an updated assessment of PM-related visibility impairment in study locations in the U.S.

                    <P>
                        With regard to an indicator for the visibility index, the 2022 PA recognizes the lack of availability of methods and an established network for directly measuring light extinction (U.S. EPA, 2022b, section 5.3.1.1). Therefore, consistent with previous reviews, the 2022 PA concludes that a visibility index based on estimates of light extinction by PM
                        <E T="52">2.5</E>
                         components derived from an adjusted version of the original IMPROVE algorithm to be the most appropriate indicator for the visibility index in this reconsideration. As described in section 5.3.1.1 of the 2022 PA, the IMPROVE algorithm estimates light extinction using routinely monitored components of PM
                        <E T="52">2.5</E>
                         and PM

                    <P>
                        With regard to averaging time, the 2022 PA notes that the evidence continues to provide support for the short-term nature of PM-related visibility effects. Given that there is no new information available regarding the time periods during which visibility impairment occurs or public preferences related to specific time periods for visibility impairment, the 2022 PA concludes that it is appropriate to continue to focus on daily visibility impairment. In so doing, the 2022 PA relies on analyses that were conducted in the 2012 review that showed relatively strong correlations between 24-hour and subdaily (
                        <E T="03">i.e.,</E>
                         4-hour average) PM
                        <E T="52">2.5</E>
                         light extinction that indicated that a 24-hour averaging time is an appropriate surrogate for the subdaily time periods relevant for visual perception (U.S. EPA, 2011, Figures G-4 and G-5; Frank, 2012). These analyses continue to provide support for a 24-hour averaging time for the visibility index in this reconsideration. Consistent with previous reviews, the 2022 PA also notes that the 24-hour averaging time may be less influenced by atypical conditions and/or atypical instrument performance than a subdaily averaging time (85 FR 82740, December 18, 2020; 78 FR 3226, January 15, 2013).
                    </P>
                    <P>With regard to the form for the visibility index, the available information continues to provide support for a 3-year average of annual 90th percentile values. Given that there is no new information to inform selection of an alternate form, as in previous reviews, the 2022 PA notes that the 3-year average form provides stability from the occasional effect of inter-annual meteorological variability that can result in unusually high pollution levels for a particular year (85 FR 82741, December 18, 2020; 78 FR 3198, January 15, 2013; U.S. EPA, 2011, p. 4-58). In so doing, the 2022 PA considers the evaluation in the 2010 Urban-Focused Visibility Assessment (UFVA) of three different statistical forms: 90th, 95th, and 98th percentiles (U.S. EPA, 2010b, Chapter 4).). In considering this evaluation of statistical forms from the 2010 UFVA, consistent with the 2011 PA, the 2022 PA notes that the Regional Haze Program targets the 20 percent most impaired days for visibility improvements in visual air quality in Federal Class I areas and that the median of the distribution of these 20 percent most impaired days would be the 90th percentile. The 2011 PA also noted that strategies that are implemented so that 90 percent of days would have visual air quality that is at or below the level of the visibility index would reasonably be expected to lead to improvements in visual air quality for the 20 percent most impaired days. Additionally, as in the 2011 PA, the 2022 PA recognizes that the available public preference studies do not address frequency of occurrence of different levels of visibility (U.S. EPA, 2022b, section 5.3.1.2). Therefore, the analyses and consideration for the form of a visibility index from the 2011 PA continue to provide support for a 90th percentile form, averaged across three years, in defining the characteristics of a visibility index in this reconsideration.</P>
                    <P>
                        With regard to the level for the visibility index, the 2022 PA recognizes that there is an additional public preference study (Malm et al., 2019) available in this reconsideration. As noted above, however, this study differs from the previously available public preference studies in several ways, which makes it difficult to integrate this newly available study with the previously available studies. Most significantly, this study was evaluated public preferences for visibility in the Grand Canyon, perhaps the most notable Class I area in the country for visibility purposes. Therefore, the 2022 PA concludes that the Grand Canyon study is not directly comparable to the other available preferences studies and public preferences of visibility impairment in the Malm et al. (2019) study are not appropriate to consider in identifying a range of levels for the target level of protection against visibility impairment for this reconsideration of the secondary PM NAAQS.

                    <P>
                        Therefore, the 2022 PA continues to rely on the same studies 
                        <SU>157</SU>
                        <FTREF/>
                         and the range of 20 to 30 dv identified from those studies in previous reviews. With regard to selecting the appropriate target level of protection for visibility impairment within this range, the 2022 PA notes that in previous reviews, a level at the upper end of the range (
                        <E T="03">i.e.,</E>
                         30 dv) was selected given the uncertainties and limitations associated with the public preference studies (U.S. EPA, 2022b, section 5.3.1.1). However, the 2022 PA also recognizes that (1) the degree of protection provided by a secondary PM NAAQS is not determined solely by any one element of the standard but by all elements (
                        <E T="03">i.e.,</E>
                         indicator, averaging time, form, and level) being considered together, and (2) decisions regarding the adequacy of the current secondary standards is a public welfare policy judgment to be made by the Administrator. As such, the Administrator may judge that a target level of protection below the upper end of the range (
                        <E T="03">i.e.,</E>
                         less than 30 dv) is appropriate, depending on his public welfare policy judgments, which draw upon the available scientific evidence for PM-related visibility effects and on analyses of visibility impairment, as well as judgments about the appropriate weight to place on the range of uncertainties inherent in the evidence and analyses.

                             As noted above, the available public preference studies include those conducted in Denver, Colorado (Ely et al., 1991), Vancouver, British Columbia, Canada (Pryor, 1996), Phoenix, Arizona (BBC Research &amp; Consulting, 2003), and Washington, DC (Abt Associates, 2001; Smith and Howell, 2009).

                        In considering the available public preference studies, consistent with past reviews, the 2022 PA concludes that it is reasonable to consider a range of 20 to 30 dv for selecting a target level of protection, including a high value of 30 dv, a midpoint value of 25 dv, and a low value of 20 dv. A target level of protection at or in the upper end of the range would focus on the Washington, DC, preference study results (Abt Associates, 2001; Smith and Howell, 2009), which identified 30 dv as the level of impairment that was determined to be “acceptable” by at least 50 percent of study participants. The public preferences of visibility impairment in the Washington, DC, study are likely to be generally representative of urban areas that do not have valued scenic elements (
                        <E T="03">e.g.,</E>
                         mountains) in the distant background. This would be more representative of areas in the middle of the country and many areas in the eastern U.S., as well as possibly some areas in the western U.S.

                    <P>
                        A target level of protection in the middle of the range would be most closely associated with the level of impairment that was determined to be “acceptable” by at least 50 percent of study participants in the Phoenix, AZ, study (BBC Research &amp; Consulting, 2003), which was 24 dv. This study, while methodologically similar to the other public preference studies, included participants that were selected as a representative sample of the Phoenix area population 
                        <SU>158</SU>
                        <FTREF/>
                         and used computer-generated images to depict specific uniform visibility impairment conditions. This study yielded the best results of the four public preference studies in terms of the least noisy preference results and the most representative selection of participants. Therefore, based on this study, the use of 25 dv to represent a midpoint within the range of target levels protection is well supported.

                             The other preference studies did not include populations that were necessarily representative of the population in the area for which the images being judged. For example, in the Denver, CO, study, participants were from intact groups (
                            <E T="03">i.e.,</E>
                             those who were meeting for other reasons) and were asked to provide a period of time during a regularly scheduled meeting to participate in the study (Ely et al., 1991). As another example, in the British Columbia, Canada, study, participants were recruited from undergraduate and graduate students enrolled in classes at the University of British Columbia's Department of Geography (Pryor, 1996).

                        A target level of protection at or just above the lower end of the range would focus on the Denver, CO, study, but may not be as strongly supported as higher levels within the range (Ely et al., 1991). Older studies, such as those conducted in Denver, CO (Ely et al., 1991), and British Columbia, Canada (Pryor, 1996), used photographs that were taken at different times of the day and on different days to capture a range of light extinction levels needed for the preference studies. Compared to studies that used computer-generated images (
                        <E T="03">i.e.,</E>
                         those in Phoenix, AZ, and Washington, DC) there was more variability in scene appearance in these older studies that could affect preference rating and includes uncertainties associated with using ambient measurements to represent sight path-averaged light extinction values rather than superimposing a computer-generated amount of haze onto the images. When using photographs, the intrinsic appearance of the scene can change due to meteorological conditions (
                        <E T="03">i.e.,</E>
                         shadow patterns and cloud conditions) and spatial variations in ambient air quality that can result in ambient light extinction measurement not being representative of the sight-path-averaged light extinction. Computer-generated images, such as those generated with WinHaze, do not introduce such uncertainties, as the same base photograph is used (
                        <E T="03">i.e.,</E>
                         there is no intrinsic change in scene appearance) and the modeled haze that is superimposed on the photograph is determined based on uniform light extinction throughout the scene.
                    </P>
                    <P>
                        In addition to differences in preferences that may arise from photographs versus computer-generated images, urban visibility preference may differ by location, and such differences may arise from differences in the cityscape scene that is depicted in the images. These differences are related to the perceived value of objects and scenes that are included in the image, as objects at a greater distance have a greater sensitivity to perceived visibility changes as light extinction is changed compared to similar scenes with objects at shorter distances. For example, a person (regardless of their location) evaluating visibility in an image with more scenic elements such as mountains or natural views may value better visibility conditions in these images compared to the same level of visibility impairment in an image that only depicts urban features such as buildings and roads. That is, if a person was shown the same level of visibility impairment in two images depicting different scenes—one with mountains in the background and urban features in the foreground and one with no mountains in the background and nearby buildings in the image without mountains in the distance—may find the amount of haze to be unacceptable in the image with the mountains in the distance because of a greater perceived value of viewing the mountains, while finding the amount of haze to be acceptable in the image with the buildings because of a lesser value of viewing the cityscape or an expectation that such urban areas may generally have higher levels of haze in general. This is consistent when comparing the differences between the Denver, CO, study results (which found the 50% acceptance criteria occurred at the best visual air quality levels among the four cities) and the Washington, DC, results (which found the 50% acceptability criteria occurred at the worst visual air quality levels among the four cities). These results may occur because the most prominent and picturesque feature of the cityscape of Denver is the visible snow-covered mountains in the distance, while the prominent and 
                        <PRTPAGE P="16320"/>
                        picturesque features of the Washington, DC, cityscape are buildings relatively nearby without prominent and/or valued scenic features that are more distant. Given these variabilities in preferences it is unclear to what extent, the available evidence provides strong support for a target level of protection at the lower end of the range. Future studies that reduce sources of noisiness and uncertainty in the results could provide more information that would support selection of a target level of protection at or just above the lower end of the range.

                        The 2022 PA presents quantitative analyses based on recent air quality that evaluate the relationship between recent air quality and calculated light extinction. As in previous reviews, these analyses explored this relationship as an estimate of visibility impairment in terms of the 24-hour PM
                        <E T="52">2.5</E>
                         standard and the visibility index. Generally, the results of the updated analyses are similar to those based on the data available at the time of the 2012 and 2020 reviews (U.S. EPA, 2022b, section 5.3.1.2). As discussed in section V.C.1.a above, the 2022 PA concludes that the available evidence continues to support a visibility index with estimated light extinction as the indicator, a 24-hour averaging time, and a 90th percentile form, averaged over three years, with a level within the range of 20 to 30 dv. These analyses evaluate visibility impairment in the U.S. under recent air quality conditions, particularly those conditions that meet the current standards, and the relative influence of various factors on light extinction. Given the relationship of visibility with short-term PM, we focus particularly on the short-term PM standards.

                             mass and component measurements that could be input into IMPROVE equation calculations for subdaily visibility impairment estimates. As detailed in the 2022 PA, there are uncertainties associated with the precision and bias of 24-hour PM

Given the uncertainties present when evaluating data quality on a 24-hour basis, the uncertainty associated with subdaily measurements may be even greater. Therefore, the inputs to these light extinction calculations are based on 24-hour average measurements of PM

                        In considering visibility impairment under recent air quality conditions, the 2022 PA recognizes that the differences in the inputs to equations estimating light extinction can influence the resulting values. For example, given the varying chemical composition of emissions from different sources, the 2.1 multiplier for converting OC to organic matter (OM) in the Lowenthal and Kumar (2016) equation may not be appropriate for all source types. At the time of the 2012 review, the EPA judged that a 1.6 multiplier was more appropriate, for the purposes of estimating visibility index at sites across the U.S., than the 1.4 or 1.8 multipliers used in the original and revised IMPROVE equations, respectively. A multiplier of 1.8 or 2.1 would account for the more aged and oxygenated organic PM that tends to be found in more remote regions than in urban regions, whereas a multiplier of 1.4 may underestimate the contribution of organic PM found in remote regions when estimating light extinction (78 FR 3206, January 15, 2013; U.S. EPA, 2012, p. IV-5). The available scientific information and results of the air quality analyses indicate that it may be appropriate to select inputs to the IMPROVE equation (
                        <E T="03">e.g.,</E>
                         the multiplier for OC to OM) on a regional basis rather than a national basis when calculating light extinction. This is especially true when comparing sites with localized PM sources (such as sites in urban or industrial areas) to sites with PM derived largely from biogenic precursor emissions (that contribute to widespread secondary organic aerosol formation), such as those in the southeastern U.S. The 2022 PA notes, however, that conditions involving PM from such different sources have not been well studied in the context of applying a multiplier to estimate light extinction, contributing uncertainty to estimates of light extinction for such conditions.

                        At the time of the 2012 review, the EPA noted that PM

                         is the size fraction of PM responsible for most of the visibility impairment in urban areas (77 FR 38980, June 29, 2012). Data available at the time of the 2012 review suggested that, generally, PM
                        <E T="52">10-2.5</E>
                         was a minor contributor to visibility impairment most of the time (U.S. EPA, 2010b) although the coarse fraction may be a major contributor in some areas in the desert southwestern region of the U.S. Moreover, at the time of the 2012 review, there were few data available from PM
                        <E T="52">10-2.5</E>

                        <E T="52">2.5</E>
                         sites where collocated PM

                         monitoring data were available. Since that time, PM

                         monitoring data are available at more locations and the analyses presented in the 2022 PA include those for light extinction estimated with coarse and fine PM at all 60 sites. Generally, the contribution of the coarse fraction to light extinction at these sites is minimal, contributing less than 1 dv to the 3-year visibility metric (U.S. EPA, 2020b, section 5.2.1.2). However, the 2022 PA notes that in the updated quantitative analyses, only a few sites were in locations that would be expected to have high concentrations of coarse PM, such as the Southwest. These results are consistent with those in the analyses in the 2019 ISA, which found that mass scattering from PM
                        <E T="52">10−2.5</E>
                         was relatively small (less than 10%) in the eastern and northwestern U.S., whereas mass scattering was much larger in the Southwest (more than 20%) particularly in southern Arizona and New Mexico (U.S. EPA, 2019a, section 13.2.4.1, p. 13-36).
                    </P>
                    <P>
                        Overall, the findings of these updated quantitative analyses are generally consistent with those in the 2012 and 2020 reviews. The 3-year visibility metric was generally below 26 dv in most areas that meet the current 24-hour PM
                        <E T="52">2.5</E>
                         standard. Small differences in the 3-year visibility metric were observed between the variations of the IMPROVE equation, which may suggest that it may be more appropriate to use one version over another in different regions of the U.S. based on PM characteristics such as particle size and composition to more accurately estimate light extinction.

                    <P>
                        Consistent with the evidence available at the time of the 2012 and 2020 reviews, and as described in detail in the 2022 PA (U.S. EPA, 2022b, section 5.3.2.2), the data remain insufficient to conduct quantitative analyses for PM effects on climate and materials. For PM-related climate effects, as explained in more detail in the proposal (88 FR 5654, January 27, 2023), our understanding of PM-related climate effects is still limited by significant key uncertainties. The recently available evidence does not appreciably improve our understanding of the spatial and temporal heterogeneity of PM components that contribute to climate forcing (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). Significant uncertainties also persist related to quantifying the contributions of PM and PM components to the direct and indirect effects on climate forcing, such as changes to the pattern of rainfall, changes to wind patterns, and effects on vertical mixing in the atmosphere (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). Additionally, while improvements have been made to climate models since the completion of the 2009 ISA, the models continue to exhibit variability in estimates of the PM-related climate effects on regional scales (
                        <E T="03">e.g.,</E>
                         ~100 km) compared to simulations at the global scale (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). While our understanding of climate forcing on a global scale is somewhat expanded since the 2012 review, significant limitations remain to quantifying potential adverse PM-related climate effects in the U.S. and how they would vary in response to incremental changes in PM concentrations across the U.S. As such, while recent research is available on climate forcing on a global scale, the remaining limitations and uncertainties are significant, and the recent global scale research does not translate directly for use at regional spatial scales. Therefore, the evidence does not provide a clear understanding at the necessary spatial scales for quantifying the relationship between PM mass in ambient air and the associated climate-related effects in the U.S. that would be necessary to evaluate or consider a level of air quality to protect against such effects and for informing consideration of a national PM standard on climate in this reconsideration (U.S. EPA, 2022b, section 5.3.2.2.1; U.S. EPA, 2019a, section 13.3).

                    <P>For PM-related materials effects, as explained in more detail in the 2022 PA (U.S. EPA, 2022b, section 5.3.2.2), the available evidence has been somewhat expanded to include additional information about the soiling process and the types of materials impacted by PM. This evidence provides some limited information to inform dose-response relationships and damage functions associated with PM, although most of these studies were conducted outside of the U.S. where PM concentrations in ambient air are typically above those observed in the U.S. (U.S. EPA, 2022b, section 5.3.2.1.2; U.S. EPA, 2019a, section 13.4). The evidence on materials effects characterized in the 2019 ISA also includes studies examining effects of PM on the energy efficiency of solar panels and passive cooling building materials, although the evidence remains insufficient to establish quantitative relationships between PM in ambient air and these or other materials effects (U.S. EPA, 2022b, section 5.3.2.1.2). While the available evidence assessed in the 2019 ISA is somewhat expanded since the time of the 2012 review, quantitative relationships have not been established for PM-related soiling and corrosion and frequency of cleaning or repair that further the understanding of the public welfare implications of materials effects (U.S. EPA, 2022b, section 5.3.2.2.2; U.S. EPA, 2019a, section 13.4). Therefore, there is insufficient information to inform quantitative analyses assessing materials effects to inform consideration of a national PM standard on materials in this reconsideration (U.S. EPA, 2022b, section 5.3.2.2.2; U.S. EPA, 2019a, section 13.4).</P>

                    <P>In drawing conclusions on the adequacy of the current secondary PM standards, in view of the advances in scientific knowledge and additional information now available, the Administrator has considered the evidence base, information, and policy judgments that were the foundation of the 2020 decision and reflects upon the body of information and evidence available in this reconsideration. In so doing, the Administrator has taken into account both evidence-based and quantitative information-based considerations, as well as advice from the CASAC and public comments. Evidence-based considerations draw upon the EPA's assessment and integrated synthesis of the scientific evidence from studies evaluating welfare effects related to visibility, climate, and materials associated with PM in ambient air as discussed in the 2022 PA (summarized in sections V.B and V.D.2 of the proposal, section V.A.2 above). The quantitative information-based considerations draw from the results of the quantitative analyses of visibility impairment presented in the 2022 PA (as summarized in section V.C of the proposal and V.A.3 above) and consideration of these results in the 2022 PA.</P>
                    <P>Consideration of the scientific evidence and quantitative information in the 2022 PA and by the Administrator is framed by consideration of a series of policy-relevant questions. Section V.B.2 below summarizes the rationale for the Administrators proposed decision, drawing from section V.D.3 of the proposal. The advice and recommendations of the CASAC and public comments on the proposed decision are addressed below in sections V.B.1 and V.B.3, respectively. The Administrator's conclusions in this reconsideration regarding the adequacy of the secondary PM standards and whether any revisions are appropriate are described in section V.D.4.</P>

                    <P>
                        In comments on the 2019 draft PA, the CASAC concurred with the staff's overall preliminary conclusions that it is appropriate to consider retaining the current secondary standards without revision (Cox, 2019b). The CASAC “finds much of the information . . . on visibility and materials effects of PM
                        <E T="52">2.5</E>
                         to be useful, while recognizing that uncertainties and controversies remain about the best ways to evaluate these effects” (Cox, 2019b, p. 13 of consensus responses). Regarding climate, while the CASAC agreed that research on PM-related effects has expanded since the 2012 review, it also concluded that “there are still significant uncertainties associated with the accurate measurement of PM to the direct and indirect effects of PM on climate” (Cox, 2019b, pp. 13-14 of consensus responses). The committee recommended that the EPA summarize the “current scientific knowledge and quantitative modeling results for effects of reducing PM
                        <E T="52">2.5</E>
                        ” on several climate-related outcomes (Cox, 2019b, p. 14 of consensus responses), while also recognizing that “it is appropriate to acknowledge uncertainties in climate change impacts and resulting welfare impacts in the United States of reductions in PM
                        <E T="52">2.5</E>
                         levels” (Cox, 2019b, p. 14 of consensus responses). When considering the overall body of scientific evidence and technical information for PM-related effects on visibility, climate, and materials, the CASAC agreed with the EPA's preliminary conclusions in the 2019 draft PA, stating that “the available evidence does not call into question the protection afforded by the current secondary PM standards and concurs that they should be retained” (Cox, 2019b, p. 3 of letter).
                    </P>
                    <P>In this reconsideration, the CASAC provided its advice regarding the current secondary PM standards in the context of its review of the 2021 draft PA (Sheppard, 2022a). In its comments on the 2021 draft PA, the CASAC first recognized that the scientific evidence is sufficient to support a causal relationship between PM and visibility effects, climate effects and materials effects.</P>
                    <P>
                        With regard to visibility effects, the CASAC recognized that the identification of a target level of protection for the visibility index is based on a limited number of studies and suggested that “additional region- and view-specific visibility preference studies and data analyses are needed to support a more refined visibility target” (Sheppard, 2022a, p. 21 of consensus responses). While the CASAC did not recommend revising either the target level of protection for the visibility index or the level of the current 24-hour PM
                        <E T="52">2.5</E>
                         standard, they did state that a visibility index of 30 deciviews “needs to be justified” and “[i]f a value of 20-25 deciviews is deemed to be an appropriate visibility target level of protection, then a secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the range of 25-35 µg/m

                    <P>
                        The CASAC also recognized the limited availability of monitoring methods and networks for directly measuring light extinction. As such, they suggest that “[a] more extensive technical evaluation of the alternatives for visibility indicators and practical measurement methods (including the necessity for a visibility FRM) is need for future reviews” (Sheppard, 2022a, p. 22 of consensus letter). The majority of the CASAC “recommend[ed] that an FRM for a directly measured PM
                        <E T="52">2.5</E>
                         light extinction indicator be developed” to inform the consideration of the protection afforded by the secondary PM standards against visibility impairment, the minority of the CASAC “believe that a light extinction FRM is not necessary to set a secondary standard protective of visibility” (Sheppard, 2022a, p. 22 of consensus responses).

                    <P>With regard to climate, the CASAC noted that “there is a causal relationship between PM and climate change, but large uncertainties remain” and recommended additional research (Sheppard, 2022a, p. 22 of consensus responses). With respect to materials damage, the CASAC noted that “[q]uantitative information on the relationship between PM and material damage is lacking” and suggested some additional studies and research approaches that could provide additional information on the effects of PM on materials and the quantitative assessment of the relationship between materials effects and PM in ambient air (Sheppard, 2022a, p. 23 of consensus responses).</P>

                    <P>In reaching his proposed conclusions, the Administrator first recognized that, consistent with the scope of this reconsideration, his decision in this reconsideration will be focused only and specifically on the adequacy of public welfare protection provided by the secondary PM standards from effects related to visibility, climate, and materials. He then considered the assessment of the current evidence and conclusions reached in the 2019 ISA and ISA Supplement; the currently available quantitative information, including associated limitations and uncertainties, described in detail and characterized in the 2022 PA; considerations and staff conclusions and associated rationales presented in the 2022 PA; and the advice and recommendations from the CASAC (88 FR 5655, January 27, 2023).</P>
                    <P>
                        With respect to visibility, the Administrator noted the longstanding body of evidence that demonstrates a causal relationship between ambient PM and effects on visibility (U.S. EPA, 2019a, section 13.2). and that visibility impairment can have implications for people's enjoyment of daily activities and for their overall sense of well-being. Therefore, as in previous reviews, he considered the degree to which the current secondary standards protect against PM-related visibility impairment. In so doing, and consistent with previous reviews, the Administrator considered the protection provided by the current secondary standards against PM-related visibility impairment in conjunction with the Regional Haze Program 
                        <SU>166</SU>
                        <FTREF/>
                         for protecting visibility in Class I areas,

                        <FTREF/>
                         which together would be expected to achieve appropriate visual air quality across all areas (88 FR 5658, January 27, 2023). The Administrator proposed to conclude that addressing visibility impairment in Class I areas is beyond the scope of the secondary PM NAAQS and that setting the secondary PM NAAQS at a level that would remedy visibility impairment in Class I areas would result in standards that are more stringent than is requisite.

                             The Regional Haze Program was established by Congress specifically to achieve “the prevention of any future, and the remedying of existing, impairment of visibility in mandatory Class I areas, which impairment results from man-made air pollution,” and that Congress established a long-term program to achieve that goal (CAA section 169A).

                             In adopting section 169A, Congress set a goal of eliminating anthropogenic visibility impairment at Class I areas, as well as a framework for achieving that goal which extends well beyond the planning process and timeframe for attaining secondary NAAQS. Thus, the Regional Haze Program will continue to contribute to reductions in visibility impairment in Class I areas.

                        In further considering what standards are requisite to protect against adverse public welfare effects from visibility impairment, the Administrator adopted an approach consistent with the approach used in previous reviews (88 FR 5645, January 27, 2023). That is, he first identified an appropriate target level of protection in terms of a PM visibility index that accounts for the factors that influence the relationship between particles in the ambient air and visibility (
                        <E T="03">i.e.,</E>
                         size fraction, species composition, and relative humidity). He then considered air quality analyses examining the relationship between this PM visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in locations meeting the current 24-hour PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards (U.S. EPA, 2022b, section 5.3.1.2; 88 FR 5650, January 27, 2023).
                    </P>
                    <P>To identify a target level of protection, the Administrator first considered the characteristics of the visibility index and defines its elements (indicator, averaging time, form, and level). With regard to the indicator for the visibility index, the Administrator recognized that there is a lack of availability of methods and an established network for directly measuring light extinction, consistent with the conclusions reached in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.1) and with the CASAC's recommendation for additional research on direct measurement methods for light extinction in their review of the 2021 draft PA (Sheppard, 2022a, p. 22 of consensus responses). Consistent with the approaches used in reaching decisions in 2012 and 2020, given the lack of such monitoring data, the Administrator preliminarily judged that estimated light extinction, as calculated using one or more versions of the IMPROVE algorithms, continues to be the most appropriate indicator for the visibility index in this reconsideration (88 FR 5659, January 27, 2023).</P>
                    <P>
                        In further defining the characteristics of a visibility index based on estimates of light extinction, the Administrator considered the appropriate averaging time, form, and level of the index. With regard to the averaging time and form, the Administrator noted that in previous reviews, a 24-hour averaging time was selected and the form was defined as the 3-year average of annual 90th percentile values. The Administrator recognized that the evidence available in this reconsideration and described in the 2022 PA continue to provide support for the short-term nature of PM-related visibility effects. Considering the available analyses of 24-hour and subdaily PM
                        <E T="52">2.5</E>
                         light extinction, and noting that the CASAC did not provide advice or recommendations with regard to the averaging time of the visibility index, the Administrator preliminarily judged that the 24-hour averaging time continues to be appropriate for the visibility index (88 FR 5659, January 27, 2023).
                    </P>
                    <P>
                        With regard to the form of the visibility index, the Administrator noted that, consistent with the approach taken in other NAAQS, including the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         NAAQS, a multi-year percentile form offers greater stability to the air quality management process by reducing the possibility that statistically unusual indicator values will lead to transient violations of the standard. Using a 3-year average provides stability from the occasional effects of inter-annual meteorological variability that can result in unusually high pollution levels for a particular year (88 FR 5659, January 27, 2023). In considering the percentile that would be appropriate with the 3-year average, the Administrator first noted that the Regional Haze Program targets the 20% most impaired days for improvements in visual air quality in Class I areas.
                        <SU>168</SU>
                        <FTREF/>
                         Based on analyses examining 90th, 95th, and 98th percentile forms, the Administrator preliminarily judged that a focus similar to the Regional Haze Program focused on improving the 20% most impaired days suggest that the 90th percentile, which represents the median of the 20% most impaired days, such that 90% of days have visual air quality that is at or below the target level of protection of the visibility 
                        <PRTPAGE P="16324"/>
                        index, would be reasonably expected to lead to improvements in visual air quality for the 20% most impaired days (88 FR 5659, January 27, 2023). In the analyses of percentiles, the results suggest that a higher percentile value could have the effect of limiting the occurrence of days with peak PM-related light extinction in areas outside of Federal Class I areas to a greater degree. However, the Administrator preliminarily concluded that it is appropriate to balance concerns about focusing on the group of most impaired days with concerns about focusing on the days with peak visibility impairment. Additionally, the Administrator noted that the CASAC did not provide advice or recommendations related to the form of the visibility index. Therefore, the Administrator preliminarily judged that it remains appropriate to define a visibility index in terms of a 24-hour averaging time and a form based on the 3-year average of annual 90th percentile values (88 FR 5659, January 27, 2023).

                            <SU>168</SU>
                             As noted above, the Administrator viewed the Regional Haze Program as a complement to the secondary PM NAAQS, and thus took into consideration its approach to improving visibility in considering how to address visibility outside of Class I areas.

                    <P>
                        With regard to the level of the visibility index, the Administrator first noted that the scientific evidence that is available to inform the level of the visibility index is largely the same as in previous reviews, and continues to provide support for a level within the range of 20 to 30 dv (88 FR 5659-5660, January 27, 2023). The Administrator recognized that significant uncertainties and limitations remained, in particular those related to the public preference studies, including methodological differences between the studies, and that the available studies may not capture the full range of visibility preferences in the U.S. population (88 FR 5659-5660, January 27, 2023). The Administrator also noted that, in their review of the 2021 draft PA, the CASAC recognized that a judgment regarding the appropriate target level of protection for the visibility index is based on a limited number of visibility preference studies, with studies conducted in the western U.S. reporting public preferences for visibility impairment associated with the lower end of the range of levels, while studies conducted in the eastern U.S. reporting public preferences associated with the upper end of the range (Sheppard, 2022a, p. 21 of consensus responses). The Administrator noted that there have long been significant questions about how to set a national standard for visibility that is not overprotective for some areas of the U.S. In establishing the Regional Haze Program to improve visibility in Class I areas, Congress noted that “as a matter of equity, the national ambient air quality standards cannot be revised to adequately protect visibility in all areas of the country.” H.R. Rep. 95-294 at 205. Thus, in reaching his proposed conclusion, the Administrator recognized that there are substantial uncertainties and limitations in the public preference studies that should be considered when selecting a target level of protection for the visibility index and took the uncertainties and variability inherent in the public preference studies into account. In so doing, the Administrator first preliminarily judged that, consistent with similar judgments in past reviews, it is appropriate to recognize that the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard is intended to address visibility impairment across a wide range of regions and circumstances, and that the current standard works in conjunction with the Regional Haze Program to improve visibility, and therefore, it is appropriate to establish a target level of protection based on the upper end of the range of levels. In considering the information available in this reconsideration and the CASAC's advice, the Administrator proposed to conclude that the protection provided by a visibility index based on estimated light extinction, a 24-hour averaging time, and a 90th percentile form, averaged over 3 years, set at a level of 30 dv (the upper end of the range of levels) would be requisite to protect public welfare with regard to visibility impairment (88 FR 5660, January 27, 2023).
                    </P>
                    <P>
                        In preliminarily concluding that it remains appropriate in this reconsideration to define the target level of protection in terms of a visibility index based on estimated light extinction as described above (
                        <E T="03">i.e.,</E>
                         with a 24-hour averaging time; a 3-year, 90th percentile form; and a level of 30 dv), the Administrator next considered the degree of protection from visibility impairment afforded by the existing secondary standards. He considered the updated analyses of PM-related visibility impairment presented in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.2), which reflect several improvements over the analyses conducted in the 2012 review. Specifically, the updated analyses examine multiple versions of the IMPROVE algorithm, including the version incorporating revisions since the 2012 review (section V.B.1.a), which provides an improved understanding of how variation in equation inputs impacts calculated light extinction (U.S. EPA, 2022b, Appendix D). In addition, unlike the analyses in the 2012 review and the 2020 PA, all of the sites included in the analyses had PM
                        <E T="52">10-2.5</E>
                         data available, which allows for better characterization of the influence of the coarse fraction on light extinction (U.S. EPA, 2022b, section 5.3.1.2).
                    </P>
                    <P>
                        The Administrator noted that the results of these updated analyses are consistent with the results from the 2012 and 2020 reviews (88 FR 5660, January 27, 2023). Regardless of the IMPROVE equation used, these analyses demonstrate that the 3-year visibility metric is at or below 28 dv in all areas meeting the current 24-hour PM
                        <E T="52">2.5</E>
                         standard (section V.C.1.b). Given the results of these analyses, the Administrator preliminarily concluded that the updated scientific evidence and technical information support the adequacy of the current secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards to protect against PM-related visibility impairment. While the inclusion of the coarse fraction had a relatively modest impact on calculated light extinction in the analyses presented in the 2022 PA, he nevertheless recognized the continued importance of the PM
                        <E T="52">10</E>
                         standard given the potential for larger impacts in locations with higher coarse particle concentrations, such as in the southwestern U.S., for which only a few sites met the criteria for inclusion in the analyses in the 2022 PA (U.S. EPA, 2019a, section 13.2.4.1; U.S. EPA, 2022b, section 5.3.1.2).

                    <P>
                        With regard to the adequacy of the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator noted that the CASAC stated that “[i]f a value of 20-25 deciviews is deemed to be an appropriate visibility target level of protection, then a secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the range of 25-35 µg/m
                        <SU>3</SU>
                         should be considered” (Sheppard, 2022a, p. 21 of consensus responses). The Administrator recognized that the CASAC recommended that the Administrator provide additional justification for a visibility index target of 30 dv but did not specifically recommend that he choose an alternative level for the visibility index. The Administrator considered the CASAC's advice, together with the available scientific evidence and quantitative information, in reaching his proposed conclusions. He recognized conclusions regarding the appropriate weight to place on the scientific and technical information examining PM-related visibility impairment including how to consider the range and magnitude of uncertainties inherent in that information is a public welfare policy judgment left to the Administrator. As such, the Administrator noted his conclusion on 
                        <PRTPAGE P="16325"/>
                        the appropriate visibility index (
                        <E T="03">i.e.,</E>
                         with a 24-hour averaging time; a 3-year, 90th percentile form; and a level of 30 dv) and his conclusions regarding the quantitative analyses of the relationship between the visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, he proposed to conclude that the current secondary standards provide requisite protection against PM-related visibility effects (88 FR 5661, January 27, 2023).
                    </P>
                    <P>
                        In reaching his proposed conclusions, the Administrator also recognized that the available evidence on visibility impairment generally reflects a continuum and that the public preference studies did not identify a specific level of visibility impairment that would be perceived as “acceptable” or “unacceptable” across the whole U.S. population. However, he noted that a judgment regarding the appropriate target level of protection would take into consideration the appropriate weight to place on the individual public preference studies. In so doing, he noted that placing more weight on the public preference study from Washington, DC, could provide support for a target level of protection at or near 30 dv, whereas placing more weight on the public preference study performed in the Phoenix, AZ, study could provide support for a target level of protection below 30 dv and down to 25 dv. While the Administrator noted that, in their review of the 2021 draft PA, the CASAC did not recommend revising the level of the current 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator recognized that they did recommend greater justification for a target level of protection of 30 dv, and noted that if a target level of protection of 20-25 dv was identified, then a secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the range of 25-35 μg/m
                        <SU>3</SU>
                         should be considered (Sheppard, 2022a, p. 21 of consensus responses). For these reasons, the Administrator solicited comment on his proposed decision to retain the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, as well as the appropriateness of a target level of protection for visibility below 30 dv and as low as 25 dv, and on revising the level of the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard to a level as low as 25 µg/m

                    <P>
                        With respect to climate effects, the Administrator recognized that a number of improvements and refinements have been made to climate models since the time of the 2012 review. However, despite continuing research and the strong evidence supporting a causal relationship with climate effects (U.S. EPA, 2019a, section 13.3.9), the Administrator noted that there are still significant limitations in quantifying the contributions of the direct and indirect effects of PM and PM components on climate forcing (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). He also recognized that models continue to exhibit considerable variability in estimates of PM-related climate impacts at regional scales (
                        <E T="03">e.g.,</E>
                         ~100 km), compared to simulations at the global scale (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). As noted above, the CASAC recognized a causal relationship between PM and climate effects but also the large uncertainties associated with quantitatively assessing such effects, particularly on a national level in the context of a U.S.-based standard. These uncertainties led the Administrator to preliminarily conclude that the scientific information available in this reconsideration remains insufficient to quantify, with confidence, the impacts of ambient PM on climate in the U.S. (U.S. EPA, 2022b, section 5.3.2.2.1) and that there is insufficient information at this time to revise the current secondary PM standards or to promulgate a distinct secondary standard to address PM-related climate effects (88 FR 5661, January 27, 2023).
                    </P>
                    <P>With respect to materials effects, the Administrator noted that the available evidence continues to support the conclusion that there is a causal relationship with PM deposition (U.S. EPA, 2019a, section 13.4). He recognized that deposition of particles in the fine or coarse fractions can result in physical damage and/or impaired aesthetic qualities. Particles can contribute to materials damage by adding to the effects of natural weathering processes and by promoting the corrosion of metals, the degradation of painted surfaces, the deterioration of building materials, and the weakening of material components. While some recent evidence on materials effects of PM is available in the 2019 ISA, the Administrator noted that this evidence is primarily from studies conducted outside of the U.S. in areas where PM concentrations in ambient air are higher than those observed in the U.S. (U.S. EPA, 2019a, section 13.4). The CASAC also noted the lack of quantitative information relating PM and material effects. Given the limited amount of information on the quantitative relationships between PM and materials effects in the U.S., and uncertainties in the degree to which those effects could be adverse to the public welfare, the Administrator preliminarily judged that the scientific information available in this reconsideration remains insufficient to quantify, with confidence, the public welfare impacts of ambient PM on materials and that there is insufficient information at this time to revise the current secondary PM standards or to promulgate a distinct secondary standard to address PM-related materials effects (88 FR 5661, January 27, 2023).</P>
                    <P>
                        Taken together, the Administrator proposed to conclude that the scientific and technical information for PM-related visibility impairment, climate impacts, and materials effects, with its attendant uncertainties and limitations, supports the current level of protection provided by the secondary PM standards as being requisite to protect against known and anticipated adverse effects on public welfare. For visibility impairment, this proposed conclusion reflected his consideration of the evidence for PM-related light extinction, together with his consideration of updated analyses of the protection provided by the current secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards. For climate and materials effects, this conclusion reflected his preliminary judgment that, although it remains important to maintain secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards to provide some degree of control over long- and short-term concentrations of both fine and coarse particles, it is generally appropriate not to change the existing secondary standards at this time and that it is not appropriate to establish any distinct secondary PM standards to address PM-related climate and materials effects at this time. As such, the Administrator recognized that current suite of secondary standards (
                        <E T="03">i.e.,</E>
                         the 24-hour PM

                        , and annual PM
                        <E T="52">2.5</E>
                         standards) together provide such control for both fine and coarse particles and long- and short-term visibility and non-visibility (
                        <E T="03">e.g.,</E>

                         effects related to PM in ambient air. His proposed conclusions on the secondary standards were consistent with advice from the CASAC, which noted substantial uncertainties remain in the scientific evidence for climate and materials effects. Thus, based on his consideration of the evidence and analyses for PM-related welfare effects, as described above, and his consideration of CASAC advice on the secondary standards, the Administrator proposed not to change those standards (
                        <E T="03">i.e.,</E>
                         the current 24-hour and annual PM

                    <P>
                        Of the public comments received on the proposal, very few were specific to the secondary PM standards. Of those commenters who did provide comments on the secondary PM standards, the majority support the Administrator's proposed decision to retain the current standards. Some commenters disagree with the Administrator's proposed conclusion to retain the current secondary standards, primarily focusing their comments on the need for a revised standard to protect against visibility impairment. In addition to the comments addressed in this notice, the EPA has prepared a Response to Comments document that addresses other specific comments related to setting the secondary PM standards. This document is available for review in the docket for this rulemaking and through the EPA's NAAQS website (
                        <E T="03">https://www.epa.gov/naaqs/particulate-matter-pm-air-quality-standards</E>

                    <P>
                        We first note that some commenters raise questions about the protection provided by the secondary PM standards for ecological effects (
                        <E T="03">e.g.,</E>
                         effects on ecosystems, ecosystem services, or species). However, consistent with the 2016 IRP and as described in the proposal (88 FR 5643, January 27, 2023), other welfare effects of PM, such as the ecological effects identified by commenters, are being considered as part of the separate, ongoing review of the secondary standards for oxides of sulfur, oxides of nitrogen and PM, and thus, those comments are beyond the scope of this action.
                    </P>
                    <P>
                        Of the comments addressing the proposed decision for the secondary PM standards, many of the commenters support the Administrator's proposed decision to retain the current secondary PM standards, without revision. This group includes industries and industry groups and State and local governments and organizations. All of these commenters generally note their agreement with the rationale provided in the proposal, with a focus on the strength of the available scientific evidence for PM-related welfare effects. Most also recognize that the scientific evidence and quantitative information available in this reconsideration have not substantially altered our previous understanding of PM-related effects on non-ecological welfare effects (
                        <E T="03">i.e.,</E>
                         visibility, climate, and materials) and do not call into question the adequacy of the current secondary standards. They find the proposed decision not to change the standards at this time to be well supported and a reasonable exercise of the Administrator's public welfare policy judgment under the CAA. The EPA agrees with these comments regarding the adequacy of the current secondary PM standards and the lack of support for revision of these standards at this time.
                    </P>
                    <P>The EPA received relatively few comments on the proposed decision that it is not appropriate to establish any distinct secondary PM standards to address PM-related climate effects. Several commenters agree that the available scientific evidence provides support for the 2019 conclusion that there is a causal relationship between PM and climate effects, and the commenters also agree with the EPA that the currently available information is not sufficient for supporting quantitative analyses for the climate effects of PM in ambient air. These commenters support the Administrator's proposed decision not to set a distinct standard for climate.</P>
                    <P>There were also very few commenters who commented on the proposed decision that it is not appropriate to establish any distinct secondary PM standards to address PM-related materials effects. As with comments on climate effects, commenters generally agree with the EPA that the evidence is not sufficient to support quantitative analyses for PM-related materials effects. However, some commenters contend that EPA failed to explain in the proposal how the current standard is appropriate to protect materials from the effects of PM. These commenters disagree with the EPA's conclusion that quantitative relationships have not been established for PM-related soiling and corrosion and frequency of cleaning or repair of materials, and cite to several studies conducted outside the U.S. that they contend that the EPA should consider since the same materials are present in the U.S. They further contend that, in discussing the available scientific evidence in the 2019 ISA for studies conducted outside of the U.S., the EPA did not provide references to these studies and, therefore, the public is unable to comment on these studies. They further State that EPA failed to consider the following information: (1) Recent work related to soiling of photovoltaic modules and other surfaces, and; (2) damage and degradation resulting from oxidant concentrations and solar radiation for a number of materials, including polymeric materials, plastic, paint, and rubber. These commenters further assert that the EPA failed to propose a standard that provides requisite protection against materials effects attributable to PM.</P>
                    <P>
                        As an initial matter, we note that the commenters submitted the same comments related to materials effects during the 2020 review. Consistent with our response in the 2020 notice of final rulemaking (85 FR 82737, December 18, 2020), we disagree with the commenters that the EPA failed to consider the relevant scientific information about materials effects available in this reconsideration. The 2019 ISA considered and included studies related to materials effects of PM, including studies conducted in and outside of the U.S., on newly studied materials including photovoltaic modules that were published prior to the cutoff date for the literature search.
                        <SU>170</SU>

                         These include the Besson et al. (2017) study referenced by the commenters (U.S. EPA, 2019a, section 13.4.2). The Grøntoft et al. (2019) study referenced by the same commenters was published after the cutoff date for the literature search for the 2019 ISA. However, the EPA provisionally considered new studies in responding to comments in the 2020 review, including the new studies highlighted by the commenters in their comments on the 2020 notice of proposed rulemaking, in the context of the findings of the 2019 ISA (see Appendix in U.S. EPA, 2020a).
                        <SU>171</SU>
                        <FTREF/>
                         Based on the provisional consideration, the EPA concluded in the 2020 review that the new studies are not sufficient to alter the conclusions reached in the 2019 ISA regarding PM and materials effects. For example, the Grøntoft et al. (2019) study was based on European air pollution which as the EPA has noted has higher concentrations (as well as diversity in sources, such as light duty diesel engines) compared to the U.S.. Thus, the EPA did not find it necessary or appropriate to reopen the air quality criteria to consider this study because it would not have been an adequate basis on which to set a NAAQS. As discussed in section I, when the EPA decided to reconsider the standards, it also decided to reopen the air quality criteria to a limited degree, based on its judgment that certain new studies were likely to be useful in reconsidering the standards. 
                        <PRTPAGE P="16327"/>
                        Based on the provisional consideration in the 2020 review and the significant data gaps that existed at that time, the EPA did not include these studies within the scope of the 2022 ISA Supplement because, although these studies provide additional support for PM-related materials, the studies would not support quantitative analyses or alternative conclusions regarding these effects. As described in section I.C.5.b above, the ISA Supplement focuses on a thorough evaluation of some studies that became available after the literature cutoff date of the 2019 ISA that could either further inform the adequacy of the current PM NAAQS or address key scientific topics that have evolved since the literature cutoff date for the 2019 ISA. In developing the ISA Supplement, the EPA focused on the non-ecological welfare effects for which the evidence supported a “causal relationship” and for which quantitative analyses could be supported by the evidence because those were the welfare effects that were most useful in informing conclusions in the 2020 PA. While the 2020 PA considered the broader set of evidence for materials effects, it concluded that there remained `substantial uncertainties with regard to the quantitative relationships with PM concentrations and concentration patterns that limit[ed] [the] ability to quantitatively assess the public welfare protection provided by the standards from these effects' (U.S. EPA, 2020b).” Therefore, the ISA Supplement did not include an evaluation of scientific evidence for PM-related materials effects. However, the EPA has once again provisionally considered new studies in this reconsideration, including the studies highlighted by the commenters, in the context of the 2019 ISA and concludes that, as in the 2020 review, these studies are not sufficient to alter the conclusions reached in the 2019 ISA regarding PM and materials effects or to provide sufficient information on which to base a secondary NAAQS. The EPA agrees there is a causal relationship between the presence of PM in the ambient air and materials effects, but to set a standard, the EPA needs not only to understand at what point materials effects become adverse to public welfare but to be able to relate specific concentrations of ambient PM to those levels of materials effects. Given the significant gaps in the evidence, particularly given that the majority of the recent evidence has been conducted outside of the U.S., establishing any quantitative relationships between particle size, concentration, chemical components, and specific measures of materials damage, such as frequency of painting or repair of materials, the EPA finds the evidence is insufficient to support a secondary NAAQS to protect against materials effects.

A limited literature update identified some additional studies that were published before December 31, 2017” (U.S. EPA, 2019a, Appendix, p. A-3).

                             As discussed in section I.D, the EPA has provisionally considered studies that were highlighted by commenters and that were published after the 2019 ISA. These studies are generally consistent with the evidence assessed in the 2019 ISA, and they do not materially alter our understanding of the scientific evidence or the Agency's conclusions based on that evidence.

                    </FTNT>
                    <P>With regard to studies conducted outside of the U.S., including those referenced by the commenters, as described in the proposal, in reaching his proposed conclusion, the Administrator recognized that while there was some newly available information related to materials effects of PM included in the 2019 ISA, “this evidence is primarily from studies conducted outside of the U.S. in areas where PM concentrations in ambient air are higher than those observed in the U.S. (U.S. EPA, 2019a, section 13.4)” (88 FR 5661, January 27, 2023). We disagree with the commenters that EPA did not provide references for these studies, nor that the lack of references inhibited the public's ability to provide comment on this proposed conclusion. First, the reference to section 13.4 in the 2019 ISA is a direct citation to the evaluation of newly available studies on PM-related materials effects, which includes citations for all materials effects evidence considered in the 2020 review and in this reconsideration. Second, section 5.3.2.1.2 of the 2022 PA considers the available scientific evidence for PM-related materials effects—including citations to the studies newly available in the 2019 ISA—and how that evidence informs conclusions regarding the adequacy of the standard (U.S. EPA, 2022b, section 5.3.2.1.2). Therefore, the EPA disagrees that the proposal failed to provide the proper references to the studies conducted outside of the U.S., and that the public was not provided the opportunity to provide comment on these studies.</P>
                    <P>Moreover, we disagree with the commenters that the EPA failed to consider quantitative information from studies available in this reconsideration. As detailed in sections 5.3.2.1.2 and 5.3.2.2 of the 2022 PA, and consistent with the information available in the 2020 review, a number of new studies are available that apply new methods to characterize PM-related effects on previously studied materials; however, the evidence remains insufficient to relate soiling or damage to specific levels of PM in ambient air or to establish quantitative relationships between PM and materials degradation. The uncertainties in the evidence identified in the 2012 review persist in the evidence in the 2020 review and in this reconsideration, with significant uncertainties and limitations to establishing quantitative relationships between particle size, concentration, chemical components, and frequency of painting or repair of materials. While some new evidence is available in the 2019 ISA, overall, the data are insufficient to conduct quantitative analyses for PM-related materials effects. Quantitative relationships have not been established between characteristics of PM and frequency of repainting or cleaning of materials, including photovoltaic panels and other energy-efficient materials, that would help inform our understanding of the public welfare implications of soiling in the U.S. (U.S. EPA, 2022b, section 5.3.2.2.2; U.S. EPA, 2019a, section 13.4). Similarly, the information does not support quantitative analyses between microbial deterioration of surfaces and the contribution of carbonaceous PM to the formation of black crusts that contribute to soiling (U.S. EPA, 2022b, section 5.3.2.2.2; U.S. EPA, 2019a, section 13.4). We also note that quantitative relationships are difficult to assess, in particular those characterized using damage functions as these approaches depend on human perception of the level of soiling deemed to be acceptable and evidence in this area remains limited in this reconsideration (U.S. EPA, 2022b, section 5.3.2.1.2). Additionally, we note the CASAC's concurrence with conclusions in the 2020 PA (Cox, 2019b, p. 13 of consensus responses) and the 2022 PA (Sheppard, 2022a, p. 23 of consensus responses) that uncertainties remain about the best way to evaluate materials effects of PM in ambient air. Further, no new studies are available in this reconsideration to link human perception of reduced aesthetic appeal of buildings and other objects to materials effects and PM in ambient air. Finally, uncertainties remain about deposition rates of PM in ambient air to surfaces and the interaction of PM with copollutants on these surfaces (U.S. EPA, 2022b, section 5.6).</P>
                    <P>
                        With respect to the commenters' assertion that the EPA failed to consider information related to materials damage and degradation from oxidant concentrations and solar radiation for a variety of materials, we first note that, even assuming these sources of materials damage are within the scope of this review of the PM NAAQS, the commenter did not provide any references to the scientific studies that they suggest that the EPA did not consider. Despite the lack of a list of specific references from the commenter, we note that the 2019 ISA considered a number of studies that examined the 
                        <PRTPAGE P="16328"/>
                        relationships between PM and several of the materials listed by the commenters (
                        <E T="03">e.g.,</E>
                         paint, plastic, rubber). However, as described in the 2022 PA, these studies did not provide additional information regarding quantitative relationships between PM and materials that could inform quantitative analyses (U.S. EPA, 2022b, sections 5.3.2.1.2 and 5.3.2.2.2), nor did they alter conclusions regarding the adequacy of the current standard (U.S. EPA, 2022b, section 5.5).
                    </P>
                    <P>As summarized above and in the proposal, the evidence in the 2020 review and in this reconsideration for PM-related effects on materials is not substantively changed from that in the 2012 review. There continues to be a lack of evidence related to materials effects that establishes quantitative relationships and supports quantitative analyses of PM-related materials soiling or damage. While the information available in the 2020 review and in this reconsideration continues to support a causal relationship between PM in ambient air and materials effects (U.S. EPA, 2019a, section 13.4), the EPA is unable to relate soiling or damage to specific levels of PM in ambient air and is unable to evaluate or consider a level of air quality to protect against such materials effects. Although the EPA did not propose a distinct level of air quality or a national standard based on air quality impacts (88 FR 5662, January 27, 2023), we did identify data gaps that prevented us from doing so. The EPA identified a number of key uncertainties and areas of future research (U.S. EPA, 2022b, section 5.6) that may inform consideration of the materials effects of PM in ambient air in future reviews of the PM NAAQS. The EPA notes that one commenter objected to the Administrator's proposed conclusion in the proposal (88 FR 5661, January 27, 2023) that in light of the available evidence for PM-related impacts on climate and on materials that it is appropriate not to change the existing secondary standards at this time. The EPA has explained, in both the proposal and this final action, the basis for its conclusion that there is insufficient evidence to identify any particular secondary standard or standards that would provide requisite protection against climate effects or materials damage. The EPA acknowledges that, as a result, the adoption of any distinct secondary PM standards for those effects would be inconsistent with the requirements of the CAA. The EPA is clarifying that it is not basing its decisions on secondary standards in this reconsideration to address these welfare effects because it has concluded that the available scientific evidence is insufficient to allow the Administrator to make a reasoned judgment about what specific standard(s) would be requisite to protect against known or anticipated adverse effects to public welfare from PM-related materials damage or climate effects.</P>
                    <P>
                        Some commenters agree with the Administrator's proposed conclusion that a target level of protection for visibility of 30 dv and the level of the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard of 35 µg/m
                        <SU>3</SU>
                         continues to be adequate to protect visibility, highlighting improvements in visibility in the U.S. Other commenters who disagree with the proposed decision indicated support for a more stringent standard for visibility impairment, although some of these commenters did not necessarily specify the alternative standard that would, in their judgment, address their concerns related to various aspects of the EPA's proposal, including the available public preference studies, specific aspects of the visibility index, and the target level of protection identified by the Administrator. Rather, most commenters focused on particular aspects of the visibility metric underlying the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, including the form, averaging time, and target level of protection necessary to protect against visibility impairment.
                    </P>
                    <P>
                        With regard to the commenters' assertion that the current secondary standards are inadequate to protect the public welfare from PM-related visibility impairment, the EPA disagrees that the currently available information is sufficient to suggest that a more stringent standard is warranted. The EPA identified and addressed in great detail the limitations and uncertainties associated with the public preference studies as a part of the 2012 review (78 FR 3210, January 15, 2013). Given that the evidence related to public preferences has not substantially changed since the 2012 review, the EPA reiterated the limitations and uncertainties inherent in the evidence as a part of the 2020 PA (U.S. EPA, 2020b, section 5.5), as well as in the 2022 PA for this reconsideration (U.S. EPA, 2022b, section 5.6). The 2022 PA highlights key uncertainties associated with public perception of visibility impairment and identifies areas for future research to inform future PM NAAQS reviews, including those raised by the commenters (U.S. EPA, 2022b, section 5.6). Specifically, the EPA agrees with commenters that there are several areas where additional information would reduce uncertainty in our interpretation of the available information for purposes of characterizing visibility impairment. As described in more detail in the 2020 PA (U.S. EPA, 2020b, p. 5-41) and the 2022 PA (U.S. EPA, 2022b, p. 5-53), briefly, these areas include: (1) Expanding the number and geographic coverage of preference studies in urban, rural, and Class I areas; (2) evaluating visibility preferences of the U.S. population today, given that the preference studies were conducted more than 15 years ago, during which time air quality in the U.S. has improved; (3) accounting for the influence of varying study methods may have on an individual's response as to what level of visibility impairment is acceptable, and; (4) information on people's judgments on acceptable visibility based on factors that can influence their perception of visibility (
                        <E T="03">e.g.,</E>
                         duration of impairment experiences, time of day, frequency of impairment).
                    </P>
                    <P>However, the EPA disagrees with the commenters that the current secondary PM standards are inadequate and should be made more stringent because of the limitations and uncertainties associated with the available public preference studies. The EPA does not view the limitations of the preference studies and other available evidence as so significant as to render the EPA unable to identify a secondary standard to protect against the adverse effects of PM on visibility, but the EPA also does not believe that the limitations themselves mean that the standards are inadequate. In fact, there is a limited amount of recently available scientific evidence to further inform our understanding of public preferences and visibility impairment is recognized by the Administrator in reaching his proposed decision not to change the current secondary PM standards at this time, given that the evidence base is largely the same as at the time of the 2012 and 2020 reviews.</P>
                    <P>
                        These same commenters further contend that the EPA failed to use the latest science to develop a visibility index, stating that the EPA failed to consider the contrast of distance methodology employed in a recent meta-analysis of available preference studies (Malm et al., 2019). Commenters claim that the EPA draws conclusions from the Malm et al. (2019) study about how to relate contrast to acceptable visibility preferences in the 2022 ISA Supplement, yet ignores the findings of the study and fails to consider the “contrast of distance” methodology in the 2022 PA and the proposal, thereby, in their view, departing from the CASAC's advice to consider this evidence in setting the secondary 
                        <PRTPAGE P="16329"/>
                        standard. Finally, the commenters assert that the EPA did not explain why the available public preference studies are adequate for analysis using a light extinction approach but not using the contrast of distance approach, and that such differential treatment is arbitrary.
                    </P>
                    <P>
                        We disagree with the commenters that the EPA did not use the latest science in evaluating the visibility index, and that the EPA failed to consider the contrast of distance methodology used in Malm et al. (2019). As the commenters state, the Malm et al. (2019) study was included in the ISA Supplement (U.S. EPA, 2022a, section 4.2.1). However, the EPA disagrees with the assertion that the ISA Supplement reached conclusions about how to relate contrast to acceptable visibility preferences. The ISA Supplement provided an overview of the Malm et al. (2019) study, stating that “[t]he main conclusion of this study was that the level of acceptable visual air quality is more consistent across studies using metrics that evaluate the distinction of an object from a background than using metrics that evaluate the greatest distance at which an object can be observed.” Furthermore, the statements that the commenters are referencing in support of this statement (
                        <E T="03">i.e.,</E>
                         U.S. EPA, 2022b, pp. 4-5-4-6) are in fact the conclusions of the study itself, rather than conclusions of the EPA. For example, the ISA Supplement notes that “Malm et al. (2019) suggested that scene-dependent metrics like contrast, which integrate the effects of b
                        <E T="52">ext</E>
                         along the sight paths between observers and landscape features, are better predictors of preference levels than universal metrics like light extinction.” The suggestion that the contrast of distance methodology is a better predictor than light extinction is one of the study authors, not the EPA. The EPA has not reached a conclusion on whether contrast of distance methodology would be a more appropriate indicator for a visibility index than estimated light extinction because the EPA finds that there is insufficient information in the record at this time to support that it is practical to evaluate, much less adopt, the contrast of distance methodology on a national basis. Specifically, the Malm et al. (2019) study does not provide as a part of their publication the specific input values to the equation to calculate the contrast of distance associated with the available public preference studies (
                        <E T="03">e.g.,</E>
                         sight paths from the images), nor do the preference studies present or make publicly available these data in their publications. In the absence of additional studies or publicly available data to further evaluate the contrast of distance methodology, the EPA is unable to consider contrast of distance as an alternative to estimated light extinction in this reconsideration, although we note that it may be appropriate to evaluate it more closely in future reviews.
                    </P>
                    <P>
                        In reaching conclusions regarding the appropriate indicator for the visibility index, the 2022 PA specifically notes “that limited new research is available on methods of characterizing visibility or on how visibility is valued by the public, such as visibility preference studies. Thus, while limited new research has further informed our understanding of the influence of atmospheric components of PM
                        <E T="52">2.5</E>
                         on light extinction, the available evidence to inform consideration of the public welfare implications of PM-related visibility impairment remains relatively unchanged” (U.S. EPA, 2022b, p. 5-50). The EPA again notes in the proposal that “there are very few studies available that use scene-dependent metrics (
                        <E T="03">i.e.,</E>
                         contrast) to evaluate public preference information, which makes it difficult to evaluate them as an alternative to the light extinction approach” (88 FR 5649-5650, January 27, 2023). To further expand on this statement, the Malm et al. (2019) study does not provide enough information to replicate the results of their contrast of distance approach to allow for a comprehensive evaluation of the potential use of this methodology in considering the results of the public preference studies for determining the target level of protection for visibility.
                    </P>
                    <P>
                        Some commenters suggests that the methodology could be approximated by simply ensuring that people could always see distant scenic elements, and that characterizing typical average and/or maximal viewing distances cross different geographical areas and regions would be a straightforward Geographical Information Systems (GIS) exercise. The EPA disagrees that this assessment would be straightforward, given the lack of data establishing viewing distances in the available scientific record and the diversity of distance to scenic elements across different areas and regions of the U.S., and finds that this approach is also not practical to adopt in this reconsideration. Finally, while the Malm et al. (2019) study is using an alternative approach for evaluating public preferences and acceptability, we note that this study is evaluating the same public preference studies that have been available for the past several decades. For these reasons, the EPA disagrees with the commenters' allegation that the EPA ignored the findings of the Malm et al. (2019) study and failed to consider the contrast of distance methodology in the 2022 PA and the proposal, and ignored the CASAC's advice to consider this study. The ISA Supplement and the 2022 PA considered the Malm et al. (2019) study, along with the full body of available scientific evidence, and took into account the uncertainties and limitations associated with the evidence for visibility preferences, in reaching conclusions regarding the adequacy of the secondary 24-hour PM
                        <E T="52">2.5</E>

                         standard to protect against visibility generally recommend revisions to the elements of the standard and visibility index (indicator, averaging time, form, and level) consistent with those supported by the CASAC and public comments in previous PM NAAQS reviews. Some commenters assert that the EPA's approach in the 2022 PA and in the proposal for this reconsideration did not evaluate options for alternative secondary PM standards and thereby is flawed. We address comments on the elements of a visibility index and a revised standard for visibility effects below.
                    </P>
                    <P>As an initial matter, the EPA disagrees to the extent commenters are suggesting that the PA is legally required to analyze options for alternative standards. The PA is a document developed by the EPA in order to assist the Administrator and the CASAC in reaching conclusions regarding the adequacy of the current standards, and its scope is determined by the EPA. Moreover, the 2022 PA did assess a wide range of information relevant to the Administrator's decision and considered a range of potential standards.</P>

                        First, in developing the 2022 PA and in responding to CASAC's advice and recommendations during its review of the 2021 draft PA, the EPA expanded upon its discussion of determining the target level of protection for the visibility index and considered the extent to which the available scientific information would alter regarding the visibility index and the appropriate target level of protection against PM-related visibility effects (U.S. EPA, 2022b, pp. 5-27-5-29). This detailed discussion expands the consideration of the target level of protection for the visibility index presented in the 2020 PA (U.S. EPA, 2020b) and the 2021 draft PA (U.S. EPA, 2021c), neither of which specifically considered the elements of the visibility index in determining the appropriate target level of protection. In 
                        <PRTPAGE P="16330"/>
                        considering the available information in the 2022 PA, the EPA concluded that the available information continued to provide support for a visibility index with a level of 30 dv, with estimated light extinction as the indicator, a 24-hour averaging time, and a 90th percentile form, averaged over three years.
                    </P>
                    <P>
                        Additionally, in summarizing the air quality and quantitative information in the proposal for this reconsideration, the EPA further expands upon the discussion added to the 2022 PA related to the target level of protection in terms of a PM
                        <E T="52">2.5</E>
                         visibility index. In so doing, the EPA considers even more extensively the available public preference studies and quantitative analyses (88 FR 5651-5652, January 27, 2023). In particular, there is a more detailed discussion of the public preference studies, including the levels of impairment determined to be “acceptable” by at least 50 percent of study participants and the methodologies used in the studies, including uncertainties and limitations associated with the methodologies (88 FR 5652, January 27, 2023). In reaching a proposed decision regarding the adequacy of the secondary PM standards, as well as the appropriate target level of protection for the visibility index, the Administrator considered the available scientific evidence and quantitative analyses, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the scientific evidence and analyses. In so doing, the Administrator proposed to conclude that the protection provided by a visibility index based on estimated light extinction, a 24-hour averaging time, and a 90th percentile form, averaged over 3 years, set at a level of 30 dv would be requisite to protect public welfare with regard to visibility impairment (88 FR 5660, January 27, 2023).
                    </P>
                    <P>
                        Having provisionally concluded that it was appropriate to define the target level of protection in terms of a visibility index based on estimated light extinction as described above (
                        <E T="03">i.e.,</E>
                         with a 24-hour averaging time; a 3-year, 90th percentile form; and a level of 30 dv), the Administrator next considered the degree of protection from visibility afforded by the current secondary PM standards. In so doing, he considered the updated analyses of PM-related visibility impairment presented in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.2) and described in more detail in the proposal (88 FR 5656, January 27, 2023), which included estimating light extinction using multiple versions of the IMPROVE algorithm and inclusion of PM
                        <E T="52">10-2.5</E>
                         data at all sites to allow for better characterization of the influence of the coarse fraction of PM on light extinction. The Administrator noted that the results of the analyses in the 2022 PA were consistent with those from the 2012 and 2020 reviews. He also recognized that, regardless of the IMPROVE equation that was used, the analyses demonstrated that the 3-year visibility metric is at or below 28 dv in all areas meting the current 24-hour PM
                        <E T="52">2.5</E>
                         standard (88 FR 5657, January 27, 2023). The Administrator also noted that, in their review of the 2021 draft PA, the CASAC stated that “[i]f a value of 20-25 deciviews is deemed to be an appropriate visibility target level of protection, then a secondary 24-hour standard in the range of 25-35 µg/m
                        <SU>3</SU>
                         should be considered (Sheppard, 2022a, p. 21 of consensus responses). The Administrator recognized that while the CASAC recommended that additional justification be provided for a visibility index target level of protection of 30 dv, they did not specifically recommend that he choose an alternative level for the visibility index. Therefore, the Administrator considered the available scientific evidence, quantitative information, and the CASAC's advice in reaching his proposed conclusions. The Administrator recognized conclusions regarding the appropriate weight to place on the scientific and technical information, including how to consider the range and magnitude of uncertainties inherent in that information, is a public welfare policy judgment left to the Administrator. As such, the Administrator noted his preliminary conclusion on the appropriate visibility index (
                        <E T="03">i.e.,</E>
                         with a 24-hour averaging time; a 3-year, 90th percentile form; and a level of 30 dv) and his preliminary conclusions regarding the quantitative analyses of the relationship between the visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, he proposed to conclude that the current secondary standards provide requisite protection against PM-related visibility effects (88 FR 5661, January 27, 2023).

                    <P>
                        However, the Administrator additionally recognized that the available evidence on visibility impairment generally reflects a continuum and that the public preference studies did not identify a specific level of visibility impairment that would be perceived as “acceptable” or “unacceptable” across the whole U.S. population. He noted a judgment of a target level of protection, below 30 dv and down to 25 dv, could be supported if more weight was put on the public preference study performed in the Phoenix, AZ, study (BBC Research &amp; Consulting, 2003). As described above, while the Administrator noted that the CASAC did not recommend revising the level of the current 24-hour PM
                        <E T="52">2.5</E>
                         standard in their review of the 2021 draft PA, they did state that, should an alternative level be considered for the visibility index, revisions to the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard should also be considered (Sheppard, 2022a, p. 21 of consensus responses). Thus, the Administrator solicited comment on the appropriateness of a target level of protection for visibility below 30 dv and down as low as 25 dv, and of revising the level of the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard to a level as low as 25 µg/m
                        <SU>3</SU>
                         (88 FR 5662, January 27, 2023), and the Administrator considered these public comments in reaching his final decision on the secondary standards. Thus, the EPA disagrees that the 2022 PA and the proposal did not adequately consider options for revising the secondary PM NAAQS.

                         standard to protect against visibility impairment, as described in the proposal (88 FR 5658-5660, January 27, 2023), the Administrator first defined an appropriate target level of protection in terms of a PM visibility index. In considering the information available in this reconsideration and the CASAC's advice, the Administrator proposed to conclude that the protection provided by a visibility index based on estimated light extinction, a 24-hour averaging time, and 90th percentile form, averaged over 3 years, set at a level of 30 dv, would be requisite to protect public welfare with regard to visibility impairment (88 FR 5660, January 27, 2023).

                        In defining this target level of protection, the Administrator first considered the indicator of such an index. He noted that, given the lack of availability of methods and an established network for directly measuring light extinctions, a visibility index based on estimates of light extinction by PM
                        <E T="52">2.5</E>
                         components derived from an adjusted version of the original IMPROVE algorithm would be most appropriate, consistent with the 2012 and 2020 reviews. As described in the proposal (88 FR 5649, January 27, 2023) and above (section V.A.2), the IMPROVE algorithm estimates light extinction using routinely monitored components of PM
                        <E T="52">2.5</E>
                         and PM

                        , along with estimates of relative humidity. The 
                        <PRTPAGE P="16331"/>
                        Administrator, while recognizing that some revisions to the IMRPOVE algorithm were newly available in the 2020 review, noted that the fundamental relationship between ambient PM and light extinction has changed very little and the different versions of the IMPROVE algorithms can appropriately reflect this relationship across the U.S. (88 FR 5658-5659, January 27, 2023). As such, he judged that defining a target level of protection in terms of estimated light extinction continues to be a reasonable approach in this reconsideration.

                    <P>
                        Some commenters who criticized the EPA's interpretation and application of the Malm et al. (2019) study also contend that an indicator based on the contrast of distance would be a significant improvement over the current indicator for the visibility index and would more accurately evaluate public preferences. However, as described in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.1), while scene-dependent metrics, such as contrast, may be useful alternative predictors of preferences compared to universal metrics like light extinction, there are a very limited number of studies that use such metrics to evaluate public preferences of visibility impairment and there is a lack of scientific evidence that supports one metric over another. Moreover, the EPA finds that even if the Administrator agreed that the contrast of distance methodology was an improvement over light extinction, there is insufficient information available to evaluate and adopt contrast of distance as an indicator for a national visibility target at this time. While, in its review of the 2021 draft PA the CASAC suggested that the EPA consider this method in developing the secondary PM standards, the CASAC also noted that “more extensive technical evaluation of the alternatives for visibility indicators and practical measurement methods” is needed to inform future reviews of the secondary PM standards (Sheppard, 2022a, p. 22 of consensus responses). The CASAC did not recommend using a different indicator for this reconsideration, with the majority of CASAC members reiterated past advice recommending development of a visibility FRM for a directly measured PM
                        <E T="52">2.5</E>
                         light extinction indicator (Sheppard, 2022a, p. 22 of consensus responses), a recommendation that was supported by other public commenters as well, and the minority of the CASAC suggested that such an FRM is not necessary. For these reasons, the EPA does not consider it feasible or appropriate to define the visibility index in terms of a contrast of distance indicator at this time.
                    </P>
                    <P>With regard to averaging time, some commenters suggested to the EPA that a secondary standard with a different form than the primary standard may be a more relevant for welfare effects. While they do not recommend a specific alternative form, the commenters point to CASAC advice in past reviews where the CASAC stated that a subdaily standard based on daylight hours better reflects visibility impairment.</P>
                    <P>
                        In defining the characteristics of a visibility index, the EPA continues to believe that a 24-hour averaging time is reasonable. This is in part based on analyses conducted in the 2012 review that showed relatively strong correlations between 24-hour and subdaily (
                        <E T="03">i.e.,</E>
                         4-hour average) PM
                        <E T="52">2.5</E>
                         light extinction (88 FR 5659, January 27, 2023; 85 FR 82740, December 18, 2020; 78 FR 3226, January 15, 2013), indicating that a 24-hour averaging time is an appropriate surrogate for the subdaily time periods relevant for visual perception. The EPA believes that these analyses continue to provide support for a 24-hour averaging time for the visibility index in this reconsideration. The EPA also recognizes that the longer averaging time may be less influenced by atypical conditions and/or atypical instrument performance (88 FR 5659, January 27, 2023; 85 FR 82740, December 18, 2020; 78 FR 3226, January 15, 2013). When taken together, the available scientific information and updated analyses of calculated light extinction available in this reconsideration continue to support that a 24-hour averaging time is appropriate when defining a target level of protection against visibility impairment in terms of a visibility index.
                    </P>
                    <P>
                        Moreover, the EPA disagrees with commenters that a secondary PM
                        <E T="52">2.5</E>
                         standard with a 24-hour averaging time does not provide requisite protection against the public welfare impacts of visibility impairment. At the time of the 2012 review, the EPA recognized that hourly or subdaily (
                        <E T="03">i.e.,</E>
                         4- to 6-hour) averaging times, within daylight hours and excluding hours with high relative humidity, are more directly related to the short-term nature of visibility impairment and the relevant viewing periods for segments of the viewing public than a 24-hour averaging time. At the time of the 2012 review, the EPA agreed that a subdaily averaging time would generally be preferable. However, the Agency noted significant data quality uncertainties associated with the instruments that would provide hourly PM
                        <E T="52">2.5</E>
                         mass concentrations necessary to inform a subdaily averaging time. These uncertainties, as described in the 2012 review, included short-term variability in hourly data from available continuous monitoring methods, which would prohibit establishing a subdaily averaging time (78 FR 3209, January 15, 2013). For all of these reasons, and consistent with the 2020 review, the EPA continues to believe that a subdaily averaging time is not supported by the information available in this reconsideration.
                    </P>
                    <P>With regard to the form of the visibility index, some commenters contend that the form used in evaluating visibility impairment is not appropriate. First, commenters contend that the EPA incorrectly stated that the CASAC did not provide advice on the 3-year, 90th percentile form of the visibility index and that the CASAC specifically recommended that the EPA further justify the metric and form, and by not doing so, the proposal arbitrarily departs from the CASAC's recommendations. The commenters also contend that the EPA fails to explain how averaging the form over three years is protective given that the public does not perceive visibility in three-year averages.</P>
                    <P>
                        We disagree with the commenters that the EPA departed from the CASAC's recommendations that “[t]he final PA should provide a robust justification for the daily light extinction percentile used in the analysis” (Sheppard, 2022a, p. 22 of consensus responses). In this statement, the CASAC did not make explicit recommendations for revisions to the form of the visibility index, as the commenters assert, but rather requested additional justification for the percentile selected for the visibility index in the 2022 PA. In response to the CASAC's recommendation after reviewing the 2021 draft PA, the EPA included a new section in the 2022 PA that explicitly discusses the elements (
                        <E T="03">i.e.,</E>
                         indicator, averaging time, form, and level) of the visibility index, including additional justification for the conclusions regarding the appropriate elements for the index (U.S. EPA, 2022b, pp. 5-27-5-29). In so doing, the 2022 PA recognizes that there is no new information available in this reconsideration to inform selection of an alternative form of the visibility index, and therefore, relied on the analyses presented in the 2010 UFVA that evaluated the different statistical forms of the visibility index. The 2022 PA also discusses the approach to improving visual air quality in Federal Class I areas as a part of the Regional Haze Program (U.S. EPA, 2022b, p. 5-28). Furthermore, as reflected in responding to public comments below, and in 
                        <PRTPAGE P="16332"/>
                        reaching his final conclusions in section V.B.4 below, the Administrator further considers the available scientific and quantitative information, the CASAC's advice, and public comments in informing his final conclusions regarding the appropriate target level of protection for the visibility index. With regard to the commenters' assertion that the EPA did not justify why averaging the form over three years is protective, we agree with the commenters that people do not perceive visibility impairment in three year averages. As described in the 2022 PA, visibility-related effects and perceived impairment are often associated with short-term PM concentrations, and therefore, the focus of the visibility analyses is centered on the adequacy of the 24-hour PM
                        <E T="52">2.5</E>
                         standard (U.S. EPA, 2022b, p. 5-29). However, as described in the 2022 PA, the 3-year average form provides stability from the occasional effect of inter-annual meteorological variability that can result in unusually high pollution levels for a particular year (U.S. EPA, 2022b, p. 5-28). Occasional meteorological variability is of particular concern for the visibility index, which can be impacted by not only PM concentrations in ambient air but also relative humidity. The D.C. Circuit has previously recognized that it is legitimate for the EPA to consider overall stability of the standard and its resulting promotion of overall effectiveness of NAAQS control programs in setting a standard.

                         283 F.3d 355, 375-76 (D.C. Cir. 2002). The 2022 PA concluded that the available information continues to provide support for a 90th percentile form, averaged over three years, and the inclusion of additional justification for the elements of the visibility index responds to the CASAC's recommendation (U.S. EPA, 2022b, section 5.3.1.2).
                    </P>
                    <P>Some commenters suggest that the 90th percentile form is too low and would result in 36 days being excluded annually, presuming that the public only finds it objectionable when visibility is worse than the standard on 37 or more days per year. The commenters also contend that the EPA's approach of using a 90th percentile form for the visibility index is inconsistent with the goals of the Regional Haze Program. In so doing, the commenters note that the Regional Haze Rule focuses on improving conditions on the worst days, while they argue that a 90th percentile form for the visibility index would ignore the 36 worst visibility days, rather than identifying them and reducing pollution on those days.</P>
                    <P>
                        In reaching conclusions regarding the appropriate form of the visibility index, the EPA is following the same approach employed in past reviews of the secondary PM NAAQS, including those in the 2012 and 2020 rulemakings. In reaching conclusions regarding the appropriate form of the visibility index in the 2011 PA, the EPA considered the percentile forms of the visibility index assessed in the 2010 PA (
                        <E T="03">i.e.,</E>
                         90th, 95th, 98th) along with the approach for improving visual air quality under the Regional Haze Program. In so doing, the 2011 PA notes that the Regional Haze Program targets the 20% most impaired days for improvements in visual air quality in Federal Class I areas (
                        <E T="03">i.e.,</E>
                         the days more impaired than the 80th percentile). The 2011 PA recognized that to increase the likelihood of improving visual air quality on the worst days, the form of the visibility index should be set well above the 80th percentile. The 2011 PA further concluded that a 90th percentile form would represent the median of the distribution of the 20% most impaired days, and meeting a visibility index with a 90th percentile form would mean that 90% of the days have visual air quality that is at or below the level of the visibility index and would reasonably expected to lead to improvements in visual air quality for the 20% most impaired days (U.S. EPA, 2011, p. 4-59). The 2022 PA noted that there is no new information from public preference studies that would inform the Administrator's consideration of the appropriate form for the visibility target index, and reached conclusions consistent with those of 2011 PA. However, as discussed below, the EPA disagrees that a focus on the 90th percentile “ignores” any days with worse visibility. It is possible to examine past patterns of air quality to judge the relationship between the 90th percentile and higher percentiles, and to assess whether achieving a 90th percentile visibility target will also result in air quality improvements, where necessary, at higher percentiles. Based on its assessment of past air quality and potential alternative percentiles for the form, the EPA judged that a 90th percentile would appropriately achieve improved air quality both above and below that percentile.
                    </P>
                    <P>Some commenters suggest that the analyses conducted in the 2010 UFVA are based on a different metric than the 24-hour average being considered in the reconsideration, that the analyses are outdated and irrelevant. Therefore, the commenters assert that relying on the analyses in the 2010 UFVA is not a rational justification for the use of a 90th percentile for the visibility index in this reconsideration. Moreover, these commenters state that, in past reviews, both the EPA and the CASAC have considered and recommended a 98th percentile form, but the proposal does not consider the 98th percentile.</P>

                        These commenters assert that the 2010 UFVA was not considering the same metric under consideration here. However, the EPA was citing to the 2010 UFVA for the conclusion that there are correlations between different statistical forms of the visibility index. To confirm whether these correlations occur under recent air quality, we conducted additional air quality analyses evaluating the visibility index using the current percentile form (
                        <E T="03">i.e.,</E>
                         90th) and two alternative forms (
                        <E T="03">i.e.,</E>
                         95th and 98th).

                        <FTREF/>
                         While a higher percentile form would further limit the number of days with peak PM-related light extinction, the analyses confirm that a 90th percentile form is effective in limiting visibility impairment at higher percentiles. Based on these analyses, depending on which version of the IMPROVE equation is used to estimate light extinction, the differences in the 3-year averages of estimated light extinction for the 90th, 95th, and 98th percentile forms are small. For example, in areas that meet the current 24-hour PM
                        <E T="52">2.5</E>
                         standard, for light extinction estimated using the original IMPROVE equation, all sites have light extinction estimates for a 90th percentile form at or below 26 dv, for a 95th or 98th percentile form at or below 29 dv.
                        <SU>173</SU>
                        <FTREF/>
                         In most locations, when estimating light extinction based on the original IMPROVE equation, the difference between a 95th or 98th percentile form and a 90th percentile form is generally less than 3 dv.
                        <SU>174</SU>
                        <FTREF/>
                         As noted in previous reviews, a change of 1 to 2 dv in light extinction under many viewing conditions will be perceived as a small, but noticeable, change in the appearance of a scene, regardless of the initial amount of visibility impairment (88 FR 5657, January 27, 2023; U.S. EPA, 2004b; U.S. EPA, 2010b). Thus, differences between a 90th percentile form and a 95th or 98th percentile form remain small, and for any of these forms of the visibility index, the estimated light extinction based on the original IMPROVE equation in areas meeting the current secondary 24-hour PM
                        <E T="52">2.5</E>

                        Some commenters disagree with the EPA's proposed conclusion that a level of 30 dv is appropriate for the visibility index and support a lower level in order to provide increased protection against visibility impairment. Commenters who support a revised level for the visibility index state that a target level of protection of 30 dv would mean that less than 10% of participants in the public preference studies, other than the Washington, DC, study, would accept visibility conditions above 29 dv. These commenters further suggest that a 75% acceptability, rather than 50% acceptability, is requisite to protect visibility sources, which would be on average a level of 21 dv when using the light extinction method or 18 dv when using the contrast of distance method. These commenters argue that, based on the available information, a target level of protection for the visibility index of approximately 20 dv would be more appropriate, and therefore, the level of the secondary 24-hour PM
                        <E T="52">2.5</E>

Other commenters who support a revised level for the visibility index suggest that public preference studies with longer sight paths to distant landscape features or with lower target levels than those in the Washington, DC study, such as the Phoenix study, would support a lower level. These commenters support revising the target level of protection for the visibility index to a 25 dv, and revising the level of the secondary 24-hour PM

                    <P>Some commenters state that EPA's justification for setting a target level of protection at the upper end of the 20 to 30 dv range is arbitrary. These commenters state that the EPA's reliance on the standard operating in many regions and circumstances as support for the upper end of the range is irrational and illegal. Moreover, these commenters contend that EPA provided no rational connection between the Regional Haze Program and the proposed decision to set the target level of protection at the upper end of the range. They suggest that the EPA proposed to rely exclusively on the Regional Haze Program to protect visibility in Class I areas and to give visibility in these areas no weight in considering the secondary PM standard and that it is not rational to entirely ignore visibility in Class I areas when setting the secondary standard. These commenters assert that the Regional Haze Program provides no rational basis for a target level of protection at the upper end of the range, nor does the EPA identify one.</P>

                        The EPA recognizes that the selection of the target level of protection for the visibility index is fundamentally a public welfare policy judgment for the Administrator. The Administrator is tasked by the CAA to judge when visibility impairment becomes an adverse effect on public welfare. It is clear that visibility impairment can become adverse to public welfare, but the Administrator does not consider that every deciview of impairment is adverse to public welfare. In considering the point at which visibility impairment becomes adverse to public welfare, such that the attainment of the secondary PM NAAQS would prevent the adverse effect, the Administrator gives weight to the public preference studies as to when visibility impairment is unacceptable. At the same time, the Administrator recognizes the limitations of these studies, which have been detailed in the proposal and the 2022 PA. Similarly, the EPA discussed the Regional Haze program in the proposal to highlight that there is a distinct program to protect against visibility impairment in Class I areas, and the existence of that program is relevant to the Administrator's judgment about the level of visibility impairment that is adverse to public welfare under CAA 109(d), because in determining what is requisite the Administrator is primarily considering visibility impairment outside of Class I areas.

                    <P>In considering how to use the results of the public preference studies, the Administrator concludes that a 50th acceptability criterion is an appropriate tool. The Administrator's task is to set standards that are neither more stringent nor less stringent than necessary, and a 50% acceptability criterion seems most appropriate to use in judging when visibility impairments become adverse, because it should more closely represent when the median person would find the impairment to be adverse. The Administrator notes this conclusion is consistent with the approach adopted in the Denver study by Ely et al. (1991) where the 50% acceptability criterion for urban visibility was first presented. This study discussed the use of the 50% acceptability criteria as a reasonable basis for setting a standard to protect visibility in urban areas. In doing so, Ely et al. (1991) noted that the 50% acceptability criterion divided the slides into two groups—those judged acceptable and those judged unacceptable by a majority of people in the study—and therefore, was reasonable since it defines the point where the majority of the study participants began to judge levels of visibility impairment as unacceptable (Ely et al., 1991).</P>
                    <P>
                        In considering the appropriate target level of protection, we next look to the available public preference studies, noting that the selecting of the range of 20 to 30 dv for the target level of protection for the visibility index is informed by the 50% acceptability values from these studies. The Denver, CO, (Ely et al., 1991) and British Columbia, Canada, (Pryor, 1996) studies met the 50% acceptability criteria at 20 dv and 19-23 dv, respectively (U.S. EPA, 2022b, Table D-8). As described in the proposal, these studies used photographs that were taken at different times of the day and on different days to capture a range of light extinction levels needed for the preference studies (88 FR 5652, January 27, 2023). Compared to studies that used computer-generated images (
                        <E T="03">i.e.,</E>
                         those in Phoenix, AZ, and Washington, DC) there was more variability in scene appearance in these older studies that could affect preference rating and includes uncertainties associated with using ambient measurements to represent sight path-averaged light extinction values rather than superimposing a computer-generated amount of haze onto the images. When using photographs, the intrinsic appearance of the scene can change due to meteorological conditions (
                        <E T="03">i.e.,</E>
                         shadow patterns and cloud conditions) and spatial variations in ambient air quality that can result in ambient light extinction measurement not being representative of the sight-path-averaged light extinction. Computer-generated images, such as those generated with WinHaze, do not introduce such uncertainties, as the same base photograph is used (
                        <E T="03">i.e.,</E>
                         there is no intrinsic change in scene appearance) and the modeled haze that is superimposed on the photograph is determined based on uniform light extinction throughout the scene. Because of the uncertainties and limitations associated with the Denver, CO, and British Columbia, Canada, the EPA concludes that it is appropriate to place less weight on these studies, and to instead focus on the public preference studies that were designed to reduce these uncertainties and limitations.

                    <P>
                        In so doing, we focus on the public preference studies that use computer-generated images (
                        <E T="03">i.e.,</E>
                         those in the Phoenix, AZ, and Washington, DC) studies. As described in the proposal, the use of computer-generated images have less variability in scene appears than in those studies that use photographs taken on different days and at different times of the days (
                        <E T="03">i.e.,</E>
                         those in the Denver, CO, study) that would be likely to influence preference rating and introduces uncertainties associated with using ambient measurements to present sight path-averaged light extinction values rather than superimposing a computer-generated amount of haze onto the images (88 FR 5652, January 27, 2023).

                    <P>The Phoenix, AZ, public preference study (BBC Research &amp; Consulting, 2003) had several strengths compared to some of the other public preference studies. The Phoenix, AZ, study had the largest number of participants (385 in 27 separate focus group sessions) of all of the public preference studies, with a sample group designed to be demographically representative of the Phoenix population at that time. The age range in the Phoenix study was also more inclusive (18-65+), with the distribution of the study participants corresponding reasonably well to the overall age distribution in the 2000 U.S. Census for the Phoenix area (BBC Research &amp; Consulting, 2003). Furthermore, the 21 images used in the Phoenix, AZ, study were developed using the WinHaze software with visual air quality ranging from 15 to 35 dv, and the view was toward the southwest, including downtown Phoenix, with the Sierra Estrella Mountains in the background at a distance of 25 miles. This study had the least noisy preference results, perhaps because a larger, more representative group of participants combined with the use of computer-generated images resulted in the smoother distribution of responses of “acceptable” visual air quality. Based on the EPA's evaluation of the public preference studies in the 2012 review, the 50% “acceptable” criteria was met at approximately 24 dv (U.S. EPA, 2010, Table 2-3).</P>
                    <P>We also consider the public preferences for the Washington, DC, studies (Abt Associates, 2001; Smith and Howell, 2009). The 2001 Washington, DC study included nine participants, and the 2009 Washington, DC, study replicated the 2001 study with 26 additional participants. Similar to the Phoenix study, the Washington, DC, studies also had the strength of having the 20 images included in the study generated using WinHaze with visual air quality ranging from 9 to 45 dv. The study depicted a scene of a panoramic view of the Potomac River, the National Mall, and downtown Washington, DC. All of the distinct buildings in the scene were within four miles and the higher elevations in the background were less than 10 miles from where the image was taken from the Arlington National Cemetary in Virginia. The 50% “acceptable” criteria was met at approximately 29 dv (U.S. EPA, 2010, Table 2-3).</P>
                    <P>
                        As described in more detail in the proposal, visibility preferences can vary by location, and such differences may arise based on the differences in the cityscape scene that is depicted in the images (88 FR 5652, January 27, 2023). In considering the geographical differences between the public preference studies, we recognize that the methodological differences between the studies may influence the resulting “acceptable” level of visibility impairment. In the Phoenix, AZ, study, the image depicted mountains in the background and urban features in the foreground, whereas the Washington, DC, study depicted nearby buildings in the image without mountains in the distance. As an initial matter, we note that the object of interest to the study participant could differ across the studies based on the scenes included in the images being evaluated—with the mountains being of greater interest in the images in the Phoenix, AZ, study, despite also depicting buildings that are similar to those shown and presumed to be of interest in the images in the Washington, DC, study (88 FR 5652, January 27, 2023). We also agree with the commenters that the distance between the object of interest and the camera is an important consideration in 
                        <PRTPAGE P="16335"/>
                        evaluating the public preference studies. Objects at greater distances from the camera location (such as those in the Phoenix, AZ, study which had a maximum distance of 42 km (U.S. EPA, 2022b, Table D-8)) have a greater sensitivity to light extinction, which alone could explain differences in preferences but coupled with an object of greater interest results in lower acceptable levels of visibility impairment. Conversely, objects at closer distances from the camera location (such as those in the Washington, DC, study which had a maximum distance of 8 km (U.S. EPA, 2022b, Table D-8)) have less sensitivity to light extinction, which coupled with objects of interest (compared to the mountainous views in the Phoenix, AZ, study) result in higher acceptable levels of visibility impairment. These studies clearly demonstrate that there are differences in the public preferences across the studies depending on the images that are used, in particular the object of interest to the study participant depicted in the image and the distance of the sight path to the object, and that such differences can influence preference results.
                    </P>
                    <P>
                        However, we note that these uncertainties and limitations have persisted from past reviews, and there is very little new information to inform conclusions regarding the interpretation of these results with regard to the target level of protection. In selecting a target level of protection, and in considering the CASAC's advice in their review of the 2021 draft PA and public comments, we conclude that it is appropriate to consider the information from the public preference studies in Washington, DC, and Phoenix, AZ, and in so doing, that it is appropriate to place weight on both of these studies in reaching conclusions on the appropriate target level of protection. The EPA recognizes that the scenes depicted in these two studies are different and may influence public preferences of visibility impairment, but notes these studies can be considered together as providing information about different areas across the U.S. with variations in the scenes that people are likely to most commonly encounter. The scene depicted in the images used in the Washington, DC, study have a mix of buildings, landmarks, and open space. On the other hand, the scene depicted in the Phoenix, AZ, study included a mix of buildings in the foreground and with more distant mountains in the background. The Administrator considers it appropriate to consider these studies together because in combination, they provide a greater diversity of scenes, which is more likely to be representative of scenes people typically experience around the country (
                        <E T="03">e.g.,</E>
                         not only in eastern metropolitan statistical areas, but also in western areas with different vistas). In considering these two studies together, the EPA recognizes that, first, the “object of interest” is a subjective judgment left to the participants of the public preference studies, and second, the images in these two studies may differ in terms of sensitivity to changes in light extinction because of the distance between the object of interest in the scene and the camera. As noted by the public commenters, the sight path for the images in the public preference studies is an important consideration in reaching conclusions regarding the appropriate target level of protection for the visibility index. In addition, the Administrator judges that giving weight to multiple studies is a more appropriate approach than focusing on a single study, particularly where the study design (including the representativeness of the participants and the scenes depicted in the images) may be important for interpreting the results of the public preference studies for informing conclusions regarding the visibility index. Given these considerations and taking into consideration public comments on the target level of protection for the visibility index, the Administrator recognizes that it is more appropriate to consider a broader range of public preferences, reflecting a broader range of scenes, by putting significant weight on both the Washington, DC, and Phoenix, AZ, studies. In so doing, he reaches the conclusion that it would be appropriate to identify secondary PM standards that generally limit visibility impairment to a level between the two studies.
                    </P>
                    <P>
                        The Administrator next considers what target level of protection would be appropriate based on the available information from these public preference studies. He first recognizes that, in the 2012 and 2020 final decisions, the then-Administrators selected a target level of protection of 30 dv, based on the upper end of the range. In so doing, the then-Administrators judged that it was appropriate to place more weight on the uncertainties associated with the public preference studies in reaching their conclusions. However, in this reconsideration, the current Administrator, while continuing to recognize that substantial uncertainties remain and that there is relatively limited new information regarding public preferences of visibility impairment, judges that it is important to balance the weight placed on uncertainties with the strength of the scientific evidence. As such, the Administrator concludes that it is appropriate to consider a target level of protection within the range of 20 to 30 dv. He further concludes that in selecting a target level within that range it is appropriate to place weight on both the mid-point of the range, as supported by the study in Phoenix, AZ, as well as the upper end, as supported by the Washington, DC, study. The Administrator notes that these two studies both employ similar methodologies that are subject to fewer uncertainties than older public preference studies (including their use of WinHaze to reduce uncertainties in the preference solicitations) although he notes that the Phoenix, AZ, study yielded the best results of the four public preference studies in terms of the least noisy preference results and the most representative selection of participants. Furthermore, he notes the differences between the scenes used for each study and finds that consideration of these studies together is more appropriate in selecting a national target for visibility protection than considering either study alone. Thus, in considering this information, along with the uncertainties and limitations of the public preference studies, the Administrator judges that it would be appropriate to select a target level of protection based on placing equal weight on the upper end of the range (
                        <E T="03">i.e.,</E>
                         30 dv) and the middle of the range (
                        <E T="03">i.e.,</E>
                         24 dv based on the Phoenix, AZ, study) in order to identify a nationwide target for protection against visibility impairment. In so doing, the Administrator concludes that a visibility index with a target level of protection of 27, defined in terms of estimated light extinction, with a 24-hour averaging time and a 3-year, 90th percentile form, would provide adequate protection against PM-related visibility effects on public welfare. Such a target level of protection balances the information from two key studies reflecting different participant preferences for different vistas in different parts of the country, appropriately weighting both near-field and more distant landscape features that may be of importance to public perceptions of visibility.

                    <P>
                        The Administrator notes that the available evidence indicates that the relationship between PM and light extinction is complex, depending on factors such as PM composition, size fraction, and age of the particles in ambient air, as well as relative 
                        <PRTPAGE P="16336"/>
                        humidity. These factors can vary across the country based on differences in regional influences, as well as meteorological conditions that can vary spatially and temporally in different areas. The Administrator also recognizes that this variability, coupled with the age of the PM depending on the distance from the source to the monitor location, also complicates the selection of which IMPROVE equation is most appropriate in different areas, although he notes that different IMPROVE equations will yield similar, but not identical, results. In so doing, the Administrator takes note of the figures presented in the 2022 PA, which depict the comparisons using the original IMPROVE equation (Figure 5-3), the revised IMPROVE equation (Figure 5-4), and the Lowenthal &amp; Kumar equation (Figure 5-6), as well as the estimated light extinction values for the three different equations presented in Table D-7.

                    <P>
                        The Administrator notes that when light extinction is calculated using the original IMPROVE equation, all 60 sites have 3-year visibility metrics below 28 dv, 58 sites are at or below 25 dv, 26 sites are at or below 20 dv, and of the two sites above 25 dv one is at 26 dv and the other has a 24-hour PM

                         well above the current 24-hour standard). Results are similar for other IMPROVE equations.

                         Based on these analyses, and consistent with the results of similar analyses in the 2012 review and the 2020 PA, the Administrator concludes that the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, with its level of 35 μg/m
                        <SU>3</SU>
                        , maintains the visibility index below 27 dv, and in fact, the current standard maintains air quality such that many areas have visibility index values that range between 15 and 25 dv for all three IMPROVE equations. In the areas that meet the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, all locations were below 27 dv when using the original and revised IMPROVE equation and all but three locations were at or below 27 dv when using the Lowenthal &amp; Kumar IMPROVE equation. Three locations (two in California and one in Utah) had air quality that was at 28 dv when the Lowenthal &amp; Kumar IMPROVE equation was used. As described in more detail in section V.A.1.3, we recognize that there are differences in the inputs for the three IMPROVE equations that can influence the resulting estimated light extinction values. The higher multiplier for converting OC to OM in the Lowenthal &amp; Kumar IMPROVE equation (
                        <E T="03">i.e.,</E>
                         a multiplier of 2.1) may be more appropriate in more remote locations where there is more aged and oxygenated organic PM than in urban locations. The three locations with air quality at 28 dv are all in urban areas (downtown Los Angeles, CA; Rubidoux, CA; Salt Lake City, UT) and tend to have higher levels of nitrate and OC, especially during the wintertime when peak PM
                        <E T="52">2.5</E>
                         concentrations typically occur. In these locations, it may be more appropriate to use either the original or revised IMPROVE equation, which have multipliers of 1.4 and 1.8, respectively, in order to refine the inputs such that estimated light extinction in these locations is more accurately characterized based on site-specific characteristics.

                    <P>
                        We also note that the four areas that exceed the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard also generally had air quality that was below 27 dv in terms of the visibility index, with only two locations experiencing a visibility index above 27 dv. One location that exceeds the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard had a visibility index of 29 dv using the original IMPROVE equation, while two locations were 30 and 32 dv using the Lowenthal &amp; Kumar IMPROVE equation. We believe attainment and maintenance of the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard will result in improved air quality in these areas, such that the visibility index values for these areas will decrease even further.
                    </P>
                    <P>
                        The Administrator recognizes that in concluding that it is appropriate to identify secondary PM standards that generally limit visibility impairment to as low as 27 dv in terms of the visibility index, the current secondary PM standards continue to provide protection against visibility impairment associated with a visibility index as low as, or even lower than, 27 dv. In so doing, he notes that when meeting the current 24-hour PM
                        <E T="52">2.5</E>
                         standard, all sites have a visibility index at or below 27 dv with the original and revised IMPROVE equations, and all but three sites at or below 27 dv with the Lowenthal and Kumar IMPROVE equation. Furthermore, the Administrator notes that this conclusion is consistent with the CASAC's advice who, in their review the 2021 draft PA, stated that “[i]f a value of 20-25 deciviews is deemed to be an appropriate visibility target level of protection, then a secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the range of 25-35 μg/m
                        <SU>3</SU>
                         should be considered” (Sheppard, 2022a, p. 21 of consensus responses). 
                    </P>
                    <P>
                        Thus, the Administrator concludes that weight on both the upper end of the range of target levels of protection for the visibility index identified in previous reviews and the mid-point of the range, as presented by the Phoenix, AZ, public preference study, and focusing on a target level of protection of 27 dv, he still judges the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard requisite to achieve that target because the standard generally maintains the visibility index at or below 27 dv such that more stringent standards are not warranted.

                    <P>
                        The EPA agrees with the commenters that the secondary PM standards work together to provide protection against short- and long-term effects of both fine and coarse particles (U.S. EPA, 2022b, section 5.5; 88 FR 5661, January 27, 2023). However, the EPA disagrees with commenters that we failed to discuss the secondary annual PM
                        <E T="52">2.5</E>
                         standard in the proposal, 2022 PA, and the 2020 final notice and that we failed to justify the adequacy of the secondary annual PM
                        <E T="52">2.5</E>
                         standard. As described in the 2022 PA and the proposal, we recognize that PM
                        <E T="52">2.5</E>
                         is the size fraction of PM responsible for most of the visibility impairment in urban areas (U.S. EPA, 2022b, section 5.3.1.2; 88 FR 5654, January 27, 2023). Analyses in the 2019 ISA found that mass scattering from PM
                        <E T="52">10-2.5</E>
                         was relatively small (less than 10%) in the eastern and northwestern U.S., whereas mass scattering was much larger in the Southwest (more than 20%), particularly in southern Arizona and New Mexico (U.S. EPA, 2019, section 13.2.4.1, p. 13-36). Given the relationship between visibility and PM
                        <E T="52">2.5</E>
                         along with the short-term nature of visibility effects, we focus more on the adequacy of the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard for providing protection against visibility impairment (U.S. EPA, 2022b, section 5.3.1.2; 88 FR 5653, January 27, 2023). In reaching his proposed conclusions, the Administrator clearly states that he “recognizes that the current suite of secondary standards (
                        <E T="03">i.e.,</E>
                         the 24-hour PM
                        <E T="52">2.5</E>
                        , 24-hour PM
                        <E T="52">10</E>
                        , and annual PM
                        <E T="52">2.5</E>
                         standards) together provide . . . control for both fine and coarse particulates and long- and short-term visibility and non-visibility (
                        <E T="03">e.g.,</E>
                         climate and materials) effects related to PM in ambient air” (88 FR 5661, January 27, 2023). Thus, by explaining how the secondary standards work together to provide protection from adverse effects, why we focus on the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard as 
                        <PRTPAGE P="16337"/>
                        most relevant to visibility impairment, and how the Administrator selected the target level of protection for the visibility index, we have addressed the CASAC's request to support the proposed decision to revise the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard while retaining the secondary annual PM
                        <E T="52">2.5</E>
                         standard. The commenters also cite to an individual CASAC member's comments for the review of the 2021 draft PA who stated “[f]or the limited scope of this reconsideration review, I see no reason to not simply set the Secondary equal to the Primary PM Standards, whatever they may be” (Sheppard, 2022a, p. A-3). This CASAC member did not provide a supporting rationale for revising the secondary standards to levels equal to the primary standards. Although areas across the country are required to attain both the primary and secondary PM
                        <E T="52">2.5</E>
                         standards so air quality is unaffected by the Administrator's decision not to revise the secondary standards to be equal to the primary standards, as described in responding to comments above, the CAA provisions require the Administrator to establish secondary standards that, in the judgment of the Administrator, are requisite to protect public welfare from known or anticipated adverse effects associated with the presence of the pollutant in ambient air. In so doing, the Administrator seeks to establish standards that are neither more nor less stringent than necessary for this purpose. The Act does not require that standards be set at a zero-risk level, but rather at a level that reduces risk sufficiently so as to protect the public welfare from known or anticipated adverse effects. The final decision on the adequacy of the current secondary standards is a public welfare policy judgment to be made by the Administrator. In reaching his proposed and final decisions regarding the adequacy of the current secondary PM standards, the Administrator considered the available scientific information and analyses about welfare effects, and associated public welfare significance, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the scientific evidence and analyses. In so doing, the Administrator concluded that the currently available scientific evidence and quantitative analyses, including uncertainties and limitations, do not call into question the adequacy of the current secondary PM standards and that the current secondary PM standards should be retained, without revision. The Administrator's judgments and decisions on the primary and secondary standards are independent and consider different aspects of the available scientific evidence and information in reaching conclusions regarding the adequacy of the standards in protecting against PM-related health and welfare effects.

                    <P>
                        This section summarizes the Administrator's considerations and conclusions related to the current secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards and presents the rationale for his decision that no change is required for those standards at this time. The CAA provisions require the Administrator to establish secondary standards that, in the judgment of the Administrator, are requisite to protect public welfare from known or anticipated adverse effects associated with the presence of the pollutant in the ambient air. In so doing, the Administrator seeks to establish standards that are neither more nor less stringent than necessary for this purpose. The Act does not require that standards be set at a zero-risk level, but rather at a level that reduces risk sufficiently so as to protect the public welfare from known or anticipated adverse effects. The final decision on the adequacy of the current secondary standards is a public welfare policy judgment to be made by the Administrator. The decision should draw on the scientific information and analyses about welfare effects, and associated public welfare significance, as well as judgments about how to consider the range and magnitude of uncertainties that are inherent in the scientific evidence and analyses. This approach is based on the recognition that the available evidence generally reflects a continuum that includes ambient air exposures at which scientists agree that effects are likely to occur through lower levels at which the likelihood and magnitude of responses become increasingly uncertain. This approach is consistent with the requirements of the provisions of the Clean Air Act related to the review of NAAQS and with how the EPA and the courts have historically interpreted the Act.
                    </P>
                    <P>Given these requirements, the Administrator's final decision in this reconsideration is a public welfare policy judgment that draws upon the scientific and technical information examining PM-related visibility impairment, climate effects and materials effects, including how to consider the range and magnitude of uncertainties inherent in that information. The Administrator recognizes that his final decision is based on an interpretation of the scientific evidence and technical analyses that neither overstates nor understates their strengths and limitations, or the appropriate inferences to be drawn. In particular, the Administrator notes that the assessment of when visibility impairment is adverse to public welfare requires a public welfare policy judgment informed by available scientific and quantitative information.</P>
                    <P>In considering the adequacy of the current secondary PM standards in this reconsideration, the Administrator has carefully considered the: (1) Policy-relevant evidence and conclusions contained in the 2019 ISA and 2022 ISA Supplement; (2) the quantitative information presented and assessed in the 2022 PA; (3) the evaluation of this evidence, the quantitative information, and the rationale and conclusions presented in the 2022 PA; (4) the advice and recommendations from the CASAC; and (5) public comments. In the discussion below, the Administrator gives weight to the 2022 PA conclusions, with which the CASAC generally concurred during their review of the 2019 draft PA and 2021 draft PA, as summarized in section IV.B.1 of the 2020 final notice and section V.D.1 of the 2022 proposal, and takes note of key aspects of the rationale for those conclusions that contribute to his decision in this reconsideration. After giving careful consideration to all of this information, the Administrator judges that no change is required for the secondary PM standards at this time.</P>
                    <P>
                        In considering the 2022 PA evaluations and conclusions, the Administrator takes note of the overall conclusions that the non-ecological welfare effects evidence and quantitative information are generally consistent with what was considered in the 2020 final decision and in the 2012 review (U.S. EPA, 2022b, section 5.5). The scientific evidence for non-ecological welfare effects in this reconsideration is largely the same as that available in the 2019 ISA and 2020 PA. As described in section I.C.5.b above, the 2022 ISA Supplement included a limited number of newly available studies on PM-related visibility effects. This newly available evidence on visibility effects, along with the full body of non-ecological welfare effects evidence assessed in the 2019 ISA, reaffirms conclusions on the visibility, climate, and materials effects recognized in the 2020 final decision and in the 2012 review, including key conclusions on which the standards are based. Further, as discussed in more 
                        <PRTPAGE P="16338"/>
                        detail above, the updated quantitative analyses of visibility impairment for areas meeting the current standards in the 2022 PA support the adequacy of the current secondary PM standards to protect against PM-related visibility impairment. The Administrator also recognizes that uncertainties and limitations continue to be associated with the available scientific evidence and quantitative information.
                    </P>
                    <P>
                        With regard to the current evidence on visibility effects, as summarized in the 2022 PA and discussed in detail in the 2019 ISA and ISA Supplement, the Administrator notes the long-standing body of evidence for PM-related visibility impairment. As in previous reviews, this evidence continues to demonstrate a causal relationship between PM in ambient air and effects on visibility (U.S. EPA, 2019a, section 13.2). The Administrator recognizes that visibility impairment can have implications for people's enjoyment of daily activities and for their overall sense of well-being. Therefore, as in previous reviews, he considers the degree to which the current secondary standards protect against PM-related visibility impairment and the degree to which PM-related visibility impairment is adverse to public welfare. In particular, in recognizing the short-term nature of visibility impairment along with the fact that PM
                        <E T="52">2.5</E>
                         is the size fraction that contributes most to light extinction, the Administrator especially focuses on the adequacy of the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in providing protection against PM-related visibility effects judged to be adverse. The Administrator also considers the protection provided by the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard against PM-related visibility impairment in conjunction with the Regional Haze Program as a means of achieving appropriate levels of protection against PM-related visibility impairment in urban, suburban, rural, and Federal Class I areas across the U.S. Programs implemented to meet the secondary PM standards, along with the requirements of the Regional Haze Program established for protecting against visibility impairment in Class I areas, would be expected to improve visual air quality across all areas of the country.
                    </P>
                    <P>
                        As described in the proposal (88 FR 5658, January 27, 2023), the Administrator recognizes that the Regional Haze Program was established by Congress specifically to achieve “the prevention of any future, and the remedying of existing, impairment of visibility in mandatory Class I areas, which impairment results from man-made air pollution,” and that Congress established a long-term program to achieve that goal (CAA section 169A). In adopting section 169, Congress set a goal of eliminating anthropogenic visibility impairment at Class I areas, as well as a framework for achieving that goal which extends well beyond the planning process and timeframe for attaining the secondary PM NAAQS. Recognizing that the Regional Haze Program will continue to contribute to reductions in visibility impairment in Class I areas, consistent with his proposed conclusions, the Administrator concludes that addressing visibility impairment in Class I areas is largely beyond the scope of the secondary PM standards and that setting the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard at a level that would remedy visibility impairment in Class I areas would result in standards that are more stringent than is requisite.
                    </P>
                    <P>
                        In further considering what standards are requisite to protect against adverse public welfare effects from visibility impairment, the Administrator concludes that it is appropriate to use an approach consistent with the approach used past reviews (88 FR 5650, January 27, 2023). He first identifies an appropriate target level of protection in terms of a PM visibility index that takes into account the factors that influence the relationship between PM in ambient air and visibility (
                        <E T="03">i.e.,</E>
                         size fraction, species composition, and relative humidity). He then considers the air quality analyses conducted in the 2022 PA that examine the relationship between the PM visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in locations that meet the current 24-hour PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards (U.S. EPA, 2022b, section 5.3.1.2).
                    </P>
                    <P>
                        In reaching conclusions regarding the target level of protection, the Administrator first considers the characteristics of the visibility index and defines its elements (indicator, averaging time, form, and level). With regard to the indicator for the visibility index, the Administrator continues to recognize that, consistent with the conclusions of the 2022 PA and the CASAC's advice in their review of the 2021 draft PA, there is a lack of availability of methods and an established network for directly measuring light extinction. Therefore, the Administrator concludes that it continues to be appropriate to using an index based on estimates of light extinction by PM
                        <E T="52">2.5</E>
                         components based on the IMPROVE algorithm. In so doing, the Administrator recognizes that the fundamental understanding of the relationship between ambient PM and light extinction has generally changed very little over time; however, several versions of the IMPROVE equation have been developed and evaluated that could be used to estimate light extinction. As at the time of the proposal, the Administrator recognizes that the results of the quantitative analyses in the 2022 PA that examined three versions of the IMPROVE equation indicate that there are very small differences in estimates of light extinction between the equations, and that it is not always clear that one version of the IMPROVE equation is more appropriate for estimating light extinction across the U.S. than other versions of the IMPROVE algorithm (88 FR 5659, January 27, 2023). He also recognizes that the selection of inputs to the IMPROVE equation (
                        <E T="03">e.g.,</E>
                         the multiplier for OC to OM) may be more appropriate on a regional basis rather than a national basis when calculating light extinction, and notes the CASAC's advice that PM-visibility relationships are region specific (Sheppard, 2022a, p. 21 of consensus responses). The Administrator further notes that neither the CASAC nor public commenters recommended a specific IMPROVE equation or an approach for using different IMPROVE equations across the U.S. Therefore, given the absence of a robust monitoring network to directly measure light extinction, the Administrator concludes that light estimated light extinction, as calculated using one or more versions of the IMPROVE algorithms, continues to be the most appropriate indicator for the visibility index.
                    </P>
                    <P>
                        Having reached the conclusion that estimated light extinction is the appropriate indicator for the visibility index, the Administrator next considers the appropriate averaging time and form of the index. With regard to the averaging time and form, the Administrator notes that in previous reviews, a 24-hour averaging time was selected and the form was defined as the 3-year average of annual 90th percentile values. As at the time of proposal, the Administrator recognizes that the available information continues to provide support for the short-term nature of visibility effects. He further recognizes that no new information is available in this reconsideration to inform his conclusions regarding averaging time, and therefore, he considers past analyses of 24-hour and subdaily PM
                        <E T="52">2.5</E>
                         light extinction to inform his conclusions on averaging time. As described in the proposal (88 FR 5659, January 27, 2023) and in responding to comments in section V.B.3 above, prior 
                        <PRTPAGE P="16339"/>
                        analyses demonstrated that there are strong correlations between 24-hour and subdaily (
                        <E T="03">i.e.,</E>
                         4-hour average) PM
                        <E T="52">2.5</E>
                         light extinction, indicating that a 24-hour averaging time is an appropriate surrogate for the subdaily time periods associated with when individuals experience visibility impairment and that a longer averaging time may also be less influenced by atypical conditions and/or atypical instrument performance. The Administrator also notes that the CASAC did not provide advice or recommendations with regard to the averaging time of the visibility index, although some public commenters referenced CASAC advice in past reviews that a subdaily standard based on daylight hours would better reflect the public welfare effects of public perceptions of visibility impairment than a 24-hour standard. However, in considering the available scientific and quantitative information, as well as the CASAC's advice in their reviews of the 2019 draft PA and 2021 draft PA, the Administrator concludes that the 24-hour averaging time continues to be appropriate for the visibility index because it is an appropriate surrogate for subdaily time periods and results in a more stable target.
                    </P>
                    <P>With regard to the form of the visibility index, the Administrator notes the approach in other NAAQS that a multi-year percentile form offers greater stability to the air quality management process by reducing the possibility that statistically unusual indicator values will lead to transient violations of the standard. He recognizes that using a 3-year average provides stability from the occasional effects of inter-annual meteorological variability (including relative humidity) that can result in unusually high pollution levels for a particular year (88 FR 5659, January 27, 2023) and recognizes that a stable standard contributes to the benefits of the NAAQS by ensuring that attainment strategies are designed to address non-transient problems and achieve durable air quality improvements. For these reasons, he concludes that a 3-year average continues to be appropriate.</P>
                    <P>
                        In considering the percentile that would be appropriate with the 3-year average, the Administrator recognizes that there is very little new information available in this reconsideration to inform selection of an alternative form of the visibility index and that the appropriate form requires the exercise of public welfare policy judgment. In selecting the appropriate target level of protection for the visibility index, the Administrator is required to assess when visibility impairment becomes adverse to public welfare, weighing both the degree of visibility impairment (in dv) and the frequency of such impairment (through the form). As with the mass-based PM air quality standard, the target level of protection for the visibility index must be selected in conjunction with the form to determine the appropriate stringency. In so doing, consistent with approaches in past reviews, the Administrator first notes that the Regional Haze Program targets the 20% most impaired days for improvements in visual air quality in Class I areas, which are the days above the 80th percentile form of the visibility index. The Administrator concludes that a percentile form set at the 80th percentile would not be likely to sufficiently improve visual air quality on the worst days based on the visibility index. In considering the information available in past reviews regarding the form of the visibility index, as well as the analysis of alternative forms based on recent air quality discussed above, the Administrator notes that a 90th percentile form would represent the median of the distribution of the 20% most impaired days, and meeting a visibility index with a 90th percentile form would reasonably be expected to lead to improvements in visual air quality for days both above and below the 90th percentile (88 FR 5660, January 27, 2023). In reaching his conclusion that a 90th percentile would appropriately achieve improved air quality both above and below that percentile, the Administrator took into consideration assessments of air quality data and potential alternative percentiles for the form. The Administrator further notes that, consistent with the conclusions in the 2011 PA and 2020 PA, the 2022 PA concluded that there is no new information from public preference studies that would suggest that a 90th percentile form is not appropriate. The Administrator also considers air quality analyses described above in responding to public comments regarding the percentile form of the visibility index. In particular, the Administrator notes that while a higher percentile form (
                        <E T="03">i.e.,</E>
                         95th or 98th) would somewhat further limit the number of days with peak PM-related light extinction, the differences in the 3-year averages of estimated light extinction for the 90th, 95th, and 98th percentile forms are small. For example, he notes that for the original IMPROVE equation, in areas that meet the current 24-hour PM
                        <E T="52">2.5</E>
                         standard, all sites have light extinction estimates for a 90th percentile form at or below 26 dv, and for a 95th or 98th percentile form light extinction estimates are at or below 29 dv.
                        <SU>176</SU>
                        <FTREF/>
                         He further notes that, in most locations when estimating light extinction based on the original IMPROVE equation, the difference between a 95th or 98th percentile form and a 90th percentile form is generally less than 3 dv.
                        <SU>177</SU>
                        <FTREF/>
                         Moreover, the Administrator concludes that a 90th percentile form achieves a very high degree of control but appropriately targets the group of worst days, rather than the few very worst days. Based on the available information and these analyses, the Administrator concludes that the information does not indicate that it would be appropriate to consider limiting the occurrence of days with peak PM-related light extinction to a greater degree, nor did the CASAC provide advice or recommendations related to the form of the visibility index. Therefore, the Administrator judges that it remains appropriate to define a visibility index in terms of a 24-hour averaging time and form based on the 3-year average of annual 90th percentile values.

                        With regard to the level of the visibility index, as at the time of proposal, the Administrator continues to recognize that there is very little new information available to inform his judgment regarding the range of levels of visibility impairment judged to be acceptable by at least 50% of study participants in the visibility preference studies,
                        <SU>178</SU>
                        <FTREF/>
                         and therefore, the range of 20 to 30 dv identified in the 2022 PA remains appropriate for considering the level of the visibility index. The Administrator also recognizes that the uncertainties and limitations associated with the public preferences identified in the 2012 and 2020 reviews continue to persist, and that these limitations and uncertainties contributed to the decisions in 2012 and 2020 that a level at the upper end of the range (
                        <E T="03">i.e.,</E>
                         30 dv) was selected. The Administrator specifically notes that, while the studies 
                        <PRTPAGE P="16340"/>
                        are methodologically similar, there are a number of factors that can influence comparability across the studies and that the available studies may not capture the full range of visibility preferences in the U.S. population, as described in more detail in section V.D.3 of the 2022 proposal (88 FR 5659-5660, January 27, 2023). The Administrator also notes the CASAC's advice in their review of the 2021 draft PA that there are a limited number of visibility preference studies available to inform the Administrator's judgment regarding the appropriate target level of protection for the visibility index (Sheppard, 2022a, p. 21 of consensus responses). In considering the available information, including uncertainties and limitation, and the CASAC's advice, the Administrator proposed to conclude that it is appropriate to consider a target level of protection for the visibility index within the range of 20 to 30 dv, and that establishing a target level of protection at the upper end of the range was appropriate. In so doing, the Administrator proposed to conclude that the protection provided by a visibility index based on estimated light extinction, a 24-hour averaging time, and a 90th percentile form, averaged over 3 years, set to a level of 30 dv would be requisite to protect public welfare with regard to visibility impairment.

                             For reasons stated above and described in the 2022 PA and proposal, the Administrator does not find it appropriate to use the most recent preference study based on the Grand Canyon study area (Malm et al., 2019) for purposes of identifying a target level of protection for the visibility index.
                        </P>
                    </FTNT>
                    <P>However, at the time of proposal, the Administrator recognized that the available evidence on visibility impairment generally reflects a continuum and that the public preference studies do not provide information about the specific level for which visibility impairment would be “acceptable” or “unacceptable” across the country, and that alternative target levels of protection could be supported. At that time, in soliciting public comments, the Administrator recognized that other interpretations, assessments, and judgments based on the available welfare effects evidence for this reconsideration could be possible (88 FR 5662, January 27, 2023).</P>
                    <P>With regard to the appropriate target level of protection for the visibility index, the Administrator first notes that while the public preference studies were conducted in several geographical areas across the U.S., and they provide insight into regional preferences for visibility impairment, none of the studies identify a specific level of visibility impairment that would be perceived as “acceptable” or “unacceptable” across the whole U.S. population. He also noted that there have been significant questions about how to set a standard for visibility that is neither overprotective nor underprotective for some areas of the U.S. As described in the proposal (88 FR 5660, January 27, 2023), in establishing the Regional Haze Program to improve visibility in Class I areas, Congress noted that “as a matter of equity, the national ambient air quality standards cannot be revised to adequately protect visibility in all areas of the country.” H.R. Rep. 95-294 at 205. For the reasons noted above, in reaching his proposed decision regarding visibility impairment, the Administrator recognized that he is not seeking to set a standard that would eliminate visibility impairment in Class I areas, but significant uncertainties remain regarding how to judge when visibility impairment becomes adverse to public welfare across the range of daily outdoor activities for Americans across the country.</P>
                    <P>
                        In reaching final conclusions regarding the available information, along with the CASAC's advice and public comments, the Administrator again considers what constitutes an appropriate target level of protection, and in particular considers whether a target level of protection below 30 dv is warranted. In so doing, he first notes the variability in public preferences of visibility impairment as demonstrated by the available public preferences, which support a range of potential target levels of protection for the visibility index from 20 to 30 dv. He also notes that this range informed the 2012 and 2020 then-Administrators final decisions that a target level of protection at the upper end of the range (
                        <E T="03">i.e.,</E>
                         30 dv) would be most appropriate, given the uncertainties and limitations associated with the public preference studies. As described in in section V.B.3 above in responding to public comments, the Administrator recognizes that a number of factors can influence public preferences across studies, in particular due to the types of scenes depicted in the images as well as the distances at which the objects of interest are located from the camera. Furthermore, the Administrator recognizes the small number of public preference studies currently available makes precise interpretations of their results challenging for determining a nationally appropriate target level of visibility protection. The Administrator also recognizes that the CASAC, in their review of 2021 draft PA, reiterated that PM-visibility relationships are region-specific based on aerosol composition, and that several public commenters emphasized the importance of the sight path distance in the images when considering how to interpret the public preference studies.
                    </P>
                    <P>
                        In this reconsideration, the Administrator judges that in determining when visibility impairment becomes adverse to public welfare for purposes of the secondary NAAQS, while continuing to recognize that substantial uncertainties remain and that there is relatively limited new information regarding public preferences of visibility impairment, it is important to balance the weight placed on uncertainties with the strength of the scientific evidence. In so doing, the Administrator first concludes that, consistent with previous reviews and his proposed decision, it remains appropriate to consider a target level of protection within the range of 20 to 30 dv. However, in further considering the available scientific and quantitative information, CASAC advice, and public comments, he further concludes that in selecting a target level within that range it is appropriate to place weight on both the middle of the range, as supported by the study in Phoenix, AZ, as well as the upper end, as supported by the Washington, DC, study. In so doing, he notes that the Washington, DC, and Phoenix, AZ, studies employ similar methodologies that are subject to fewer uncertainties than older public preference studies (including their use of WinHaze to reduce uncertainties in the preference solicitations) although he does note that the Phoenix, AZ, study yielded the best results of the four public preference studies in terms of the least noisy preference results and the most representative selection of participants. Further, the Administrator judges that this approach would take into account scenes that are similar to both the Washington, DC, study and Phoenix, AZ, study, which would be more representative of the “typical” scenes encountered across more areas of the U.S. than an approach that places weight on just one study or on studies conducted in certain geographical areas of the country. In considering this information, along with the uncertainties and limitations of the public preference studies, the Administrator judges that it would be appropriate to select a target level of protection based on placing equal weight on the upper end of the range (
                        <E T="03">i.e.,</E>
                         30 dv) and the middle of the range (
                        <E T="03">i.e.,</E>
                         24 dv based on the Phoenix, AZ, study) in order to provide protection against visibility impairment in different geographical areas of the U.S. For these reasons, the Administrator concludes that a visibility index with a target level of protection of 27 dv, 
                        <PRTPAGE P="16341"/>
                        defined in terms of estimated light extinction, with a 24-hour averaging time and a 3-year, 90th percentile form, would provide adequate protection against PM-related visibility effects. In reaching this conclusion, the Administrator judges that such a target level of protection balances the information from these two key public preference studies in such a way appropriately weighs both near-field and more distant landscape features that may be of importance to public perceptions of visibility.
                    </P>
                    <P>In further considering the appropriate target level of protection for the visibility index, the Administrator again recognizes the complexity of the relationship between PM and light extinction which is dependent on a number of factors, including PM composition, size fraction, and age of the particles in ambient air, as well as relative humidity. As noted in responding to comments above, these factors can vary geographically across the U.S. and local or regional meteorological conditions can also vary spatially and temporally. These factors are critical inputs to the IMPROVE equation and can influence the resulting estimated light extinction such that it is not a straightforward comparison between estimated light extinction in one area of the country versus another. Moreover, the Administrator recognizes that there is variability in estimated light extinction depending on the version of the IMPROVE equation that is used. As described in more detail in the 2022 PA and the proposal, and in reaching his decisions on the indicator of the visibility index above, the Administrator notes that the 2022 PA concluded that one version of the IMPROVE equation is not more accurate or precise in estimating light extinction, and that difference in locations may support the selection of inputs into the IMPROVE equation or of the appropriate IMPROVE equation to estimate light extinction on a regional basis rather than on a national basis.</P>
                    <P>In considering the available information, including variations in both public preferences of visibility impairment and estimates of light extinction using one or more IMPROVE equation, as well as the CASAC's advice in their review of the 2019 draft PA and 2021 draft PA and public comments, the Administrator judges that a target level of protection of 27 dv would be appropriate. In so doing, he concludes that a target level of protection above 27 dv would not provide adequate protection against PM-related visibility impairment based on the 50% acceptability values when both the Washington, DC, and Phoenix, AZ, studies are considered. However, he also notes that when considering the 50% acceptability values from studies conducted in different areas of the U.S. and with different scenes and images depicted, the available public preference studies do not provide a “bright line” at and above which visibility impairment is considered adverse to public welfare. He further recognizes that, as discussed just above, there are a number of region-specific factors that can influence light extinction, and thereby influence visibility impairment, as well as variations in public preferences of visibility impairment based on the available studies, that complicate selection of a single target level of protection that would be appropriate for a national visibility index. While the Administrator recognizes that the uncertainties and limitations associated with public preferences of visibility and estimating light extinction have persisted over the last several PM NAAQS reviews, he also recognizes that in reaching conclusions regarding the appropriate target level of protection for the visibility index also involves public welfare policy judgments regarding how to appropriately consider the particular uncertainties around identifying when visibility impairment becomes adverse to public welfare, and the limitations on relying on the public preference studies.</P>
                    <P>
                        The Administrator also places weight on the high degree of spatial and temporal variability in PM composition and relative humidity across the U.S. in considering a target level of protection. This approach of establishing a target level of protection that takes into account 50% acceptability values from both eastern and western sites is a more appropriate basis for determining the requisite level of protection against known or anticipated adverse effects on public welfare across diverse locations, 
                        <E T="03">i.e.,</E>
                         a standard that is neither more nor less stringent than necessary nationwide. Specifically, the Administrator judges that a target level of protection for the visibility index focused on maintaining estimated light extinction between the upper end of the range of the target levels of protection (
                        <E T="03">i.e.,</E>
                         30 dv based on the Washington, DC, study) and the middle of the range (
                        <E T="03">i.e.,</E>
                         24 dv based on the Phoenix, AZ, study) to be more appropriate for a nationwide standard to protect against visibility impairment compared to a value derived from one location or one type of scene alone. For these reasons, in selecting a target level of protection, the Administrator concludes that a target level of protection somewhere between the upper end and middle of the range is appropriate because he judges that this approach, in conjunction with the Regional Haze program, is sufficient, but not more stringent than necessary, to protect against adverse effects on public welfare. Thus, he concludes a secondary 24-hour PM
                        <E T="52">2.5</E>
                         NAAQS should be evaluated based on its ability to provide protection against visibility impairment associated with estimated light extinction of 27 dv based on estimated light extinction, a 24-hour averaging time, and a 90th percentile form, averaged over 3 years.
                    </P>
                    <P>Having concluded that it is appropriate to identify a target level of protection in terms of a visibility index based on estimated light extinction as described above, the Administrator next considers the degree of protection from visibility impairment afforded by the current secondary PM standards. He considers the updated analyses of PM-related visibility impairment presented in the 2022 PA (U.S. EPA, 2022b, section 5.3.1.2) and described in section V.B.1.a of the proposal, and notes that the results of the analyses are consistent with the results from the 2012 and 2020 reviews.</P>
                    <P>
                        Taking into consideration the full body of scientific evidence and technical information concerning the known and anticipated effects of PM on visibility impairment, the Administrator concludes that the current secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards are requisite to protect against PM-related visibility impairment. While the inclusion of the coarse fraction had a relatively modest impact on calculated light extinction in the analyses presented in the 2022 PA, he recognizes the continued importance of the PM
                        <E T="52">10</E>
                         standard given the potential for larger impacts in locations with higher coarse particle concentrations, such as in the southwestern U.S., for which only a few sites met the criteria for inclusion in the analyses in the 2022 PA (U.S. EPA, 2019a, section 13.2.4.1; U.S. EPA, 2022b, section 5.3.1.2).
                    </P>
                    <P>
                        With regard to the adequacy of the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, the Administrator notes that, in their review of the 2021 draft PA, the CASAC stated that “[i]f a value of 20-25 deciviews is deemed to be an appropriate visibility target level of protection, then a secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard in the range of 25-35 µg/m
                        <SU>3</SU>
                         should be considered” (Sheppard, 2022a, p. 21 of consensus responses). The Administrator recognizes that the CASAC recommended that the Administrator provide additional justification for a visibility index target 
                        <PRTPAGE P="16342"/>
                        of 30 dv but did not specifically recommend that he choose an alternative level for the visibility index. The Administrator carefully considered the advice of CASAC and the public comments and concluded that a lower target level of visibility was appropriate in order to properly reflect both a broader set of studies and a broader range of vistas that were the subject of those studies. However, in their review of the 2021 draft PA, the CASAC recognized that even a visibility index target in the range of 20-25 dv could still warrant retention of the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard. The Administrator also considers the advice from the CASAC in their review of the 2019 draft PA, who “recogniz[ed] that uncertainties. . .remain about the best way to evaluate” PM-related visibility effects (Cox, 2019b, p. 13 consensus responses). The Administrator considered the CASAC's advice, together with the available scientific evidence and quantitative information, in reaching his conclusions.
                    </P>
                    <P>
                        The Administrator recognizes that conclusions regarding the appropriate weight to place on the scientific and technical information examining PM-related visibility impairment, including how to consider the range and magnitude of uncertainties inherent in that information, is a public welfare policy judgment left to the Administrator. In reaching his final decision in 2020, the then-Administrator noted that the available evidence regarding visibility effects had changed very little since the 2012 review, specifically recognizing that, as evaluated in the 2019 ISA, there were no new visibility studies that were conducted in the U.S. and there was little new information available with regard to acceptable levels of visibility impairment in the U.S. (85 FR 82742, December 18, 2020). As such, the then-Administrator concluded that the protection provided by a standard defined in terms of a PM
                        <E T="52">2.5</E>
                         visibility index, with a 24-hour averaging time, a 90th percentiles form averaged over three years, set at a level of 30 dv, was requisite to protect public welfare against visibility impairment (85 FR 82743, December 18, 2020). He also recognized that there was some new information to inform quantitative analyses of light extinction, but that the results of the analyses conducted in the 2020 PA were consistent with those from the 2012 review. The then-Administrator recognized that the analyses demonstrated that the 3-year visibility metric was at or below about 30 dv in all areas that met the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard, and was below 25 dv in most of those areas (85 FR 82743, December 18, 2020). Therefore, the Administrator judged that the secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard provided sufficient protection for visual air quality of 30 dv, which he judged appropriate (88 FR 82744, December 18, 2020). In this reconsideration, the ISA Supplement evaluated newly available studies on public preferences for visibility impairment and/or development methodologies or conducted quantitative analyses of light extinction. In considering the available scientific and quantitative information, including that newly available in this reconsideration, the current Administrator reached the same preliminary conclusions in the notice of proposed rulemaking regarding the 3-year visibility index and the current secondary PM standards as the then-Administrator in the 2020 final decision. However, in light of public comments on the proposal, the Administrator has further considered the available scientific evidence and information, as well as the CASAC's advice regarding visibility effects in their review of the 2021 draft PA. In so doing, the Administrator judges that it is appropriate to place more weight on certain aspects of the evidence that he had placed less weight on in reaching his proposed conclusions (
                        <E T="03">i.e.,</E>
                         he focused on the both the middle and the upper end of the range of the 50% acceptability values from the available public preference studies). As such, the Administrator notes his conclusion on the appropriate visibility index (
                        <E T="03">i.e.,</E>
                         with a 24-hour averaging time; a 3-year, 90th percentile form; and a level of 27 dv), which takes into account the regional variations in public preferences and equations for estimating light extinction, and his conclusions regarding the quantitative analyses of the relationship between the visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard. In so doing, the Administrator concludes that the current secondary standards provide requisite protection against PM-related visibility effects.
                    </P>
                    <P>
                        With respect to climate effects, as at the time of proposal, the Administrator recognizes that a number of improvements and refinements have been made to climate models since the time of the 2012 review. However, despite continuing research and the strong evidence supporting a causal relationship with climate effects (U.S. EPA, 2019a, section 13.3.9), the Administrator notes that there are still significant limitations in quantifying the contributions of the direct and indirect effects of PM and PM components on climate forcing (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). He also recognizes that models continue to exhibit considerable variability in estimates of PM-related climate impacts at regional scales (
                        <E T="03">e.g.,</E>
                         ~100 km), compared to simulations at the global scale (U.S. EPA, 2022b, sections 5.3.2.1.1 and 5.5). Moreover, the effects of PM on climate are diverse as well as uncertain. Depending on the circumstances, the radiative forcing effects of PM in the atmosphere can vary, such that positive forcing could result in warming of the Earth's surface, whereas a negative forcing could result in cooling (U.S. EPA, 2019a, section 13.3.2.2). The resulting uncertainty leads the Administrator to conclude that the scientific information available in this reconsideration remains insufficient to quantify, with confidence, the impacts of ambient PM on climate in the U.S. (U.S. EPA, 2022b, section 5.3.2.2.1) and that there is not an adequate scientific basis to link attainment of any particular PM concentration in ambient air in the U.S. to specific climate effects. Consequently, the Administrator judges that there is insufficient information at this time to revise the current secondary PM standards or to promulgate a distinct secondary standard to address PM-related climate effects.
                    </P>
                    <P>
                        With respect to materials effects, the Administrator notes that the available evidence continues to support the conclusion that there is a causal relationship with PM deposition (U.S. EPA, 2019a, section 13.4). He recognizes that deposition of particles in the fine or coarse fractions can result in physical damage and/or impaired aesthetic qualities. Particles can contribute to materials damage by adding to the effects of natural weathering processes and by promoting the corrosion of metals, the degradation of painted surfaces, the deterioration of building materials, and the weakening of material components. While some recent evidence on materials effects of PM is available in the 2019 ISA, the Administrator notes that this evidence is primarily from studies conducted outside of the U.S. in areas where PM concentrations in ambient air are higher than those observed in the U.S. (U.S. EPA, 2019a, section 13.4). Given the limited amount of information on the quantitative relationships between PM and materials effects in the U.S., and uncertainties in the degree to which those effects could be adverse to the public welfare, the Administrator judges that the available scientific information 
                        <PRTPAGE P="16343"/>
                        remains insufficient to quantify, with confidence, the public welfare impacts of ambient PM on materials and that there is insufficient information at this time to revise the current secondary PM standards or to promulgate a distinct secondary standard to address PM-related materials effects.
                    </P>
                    <P>
                        Taken together, the Administrator concludes that the scientific and quantitative information for PM-related non-ecological welfare effects (
                        <E T="03">i.e.,</E>
                         visibility, climate, and materials),
                        <SU>179</SU>
                        <FTREF/>
                         along with the uncertainties and limitations, supports the current level of protection provided by the secondary PM standards as being requisite to protect against known and anticipated adverse effects on public welfare. For visibility impairment, this conclusion reflects his consideration of the evidence for PM-related light extinction, together with his consideration of updated air quality analyses of the relationship between the visibility index and the current secondary 24-hour PM
                        <E T="52">2.5</E>
                         standard and the protection provided by the current secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards. For climate and materials effects, this conclusion reflects his judgment that, although it remains important to maintain secondary PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                         standards to provide some degree of control over long- and short-term concentrations of both fine and coarse particles, it is appropriate not to change the existing secondary standards at this time and that it is not appropriate to establish any distinct secondary PM standards to address PM-related climate and materials effects at this time. As such, the Administrator recognizes that current suite of secondary standards (
                        <E T="03">i.e.,</E>
                         the 24-hour PM
                        <E T="52">2.5</E>

                        <E T="52">2.5</E>
                         standards) together provide such control for both fine and coarse particles and long- and short-term visibility and non-visibility (
                        <E T="03">e.g.,</E>
                         climate and materials) effects related to PM in ambient air. His conclusions on the secondary standards are consistent with advice from the CASAC, which noted substantial uncertainties remain in the scientific evidence for climate and materials effects, as well as the majority of public comments on the secondary PM standards. Thus, based on his consideration of the evidence and analyses for PM-related welfare effects, as described above, and his consideration of CASAC advice and public comments on the secondary standards, the Administrator concludes that it is appropriate not to change those standards (
                        <E T="03">i.e.,</E>
                         the current 24-hour and annual PM

                         design values, asserting that it would amount to an imposition of a more stringent PM

                         standard due to the potential high bias of FEMs. The EPA disagrees with this assertion because site-level design values would combine data from any high biased FEM with other monitors at the site rather than calculate a monitor-level design value with data solely from that high-biased FEM. The EPA tested the impact of calculating site-level PM
                        <E T="52">10</E>
                         design values for the 2019-2021 period by assigning the lowest parameter occurrence code as the primary monitor and calculating site-level design values. Most resulting site-level design values were either identical to or in-between the multiple monitor-level design values at the site. Combining data from two or more monitors also has the benefit of increasing the number of valid sample days at many sites. For the 2019-2021 test period, approximately 10% of the sites with more than one monitor went from having multiple invalid design values to a single valid design value.

Because the procedure for calculating PM

                         design values on a site-level basis being finalized here will require monitoring agencies to designate a primary monitor for each site in their annual network plans (88 FR 5694, January 27, 2023; App. K, 1.0(b)), the EPA agrees with the commenter that this footnote was unnecessary.

                         FEMs, which requires testing at wide range of ambient concentrations. For this reason, Table C-4 specifies a minimum number of valid sample sets to be conducted at specified high concentrations. However, due to the dramatic decrease in ambient PM concentrations in the past two decades, these number of valid test days at high concentrations has been difficult to achieve. Accordingly, the EPA proposed to revise the testing specifications for high concentration events in Table C-4 to reflect current levels of ambient PM for all three PM metrics. In addition to the revision of the ambient PM concentration specifications to Table C-4, there are also several entry errors that required correction.

The EPA received mixed comments in support of and in opposition to this proposed revision. The sole commenter opposing the proposed revision indicated that the proposed PGVP requirements would be additional and is concerned with an increased resource burden. But the EPA responds that the PGVP requirements that were proposed to be added are consistent with the existing PGVP requirements in 40 CFR 75.21(g), and PGVP has been defined as a regulatory requirement since 2016 (81 FR 17263, March 28, 2016), so the proposed part 58 changes are not “additional” to existing regulations.

                         (88 FR 5666, January 27, 2023). The proposed new statistics are designed to address the high imprecision values that result from using these calculations to compare low concentrations that are now more routinely observed in the networks. The EPA received several comments in support of this change in general, but some commenters indicated that they believed there was an error in the new calculation that may result in high imprecision from the calculation of the equation. The EPA reviewed the technical memorandum and confirmed that a multiplier of 100 was unintentionally left in the proposed relative difference equation, Equation 6. Also, equation 6 was corrected from a normalized percent difference to a normalized relative percent difference that is appropriate for comparing collocated pairs at low concentrations. The technical memorandum titled “Task 16 on PEP/NPAP Task Order: Bias and Precision DQOs for the PM

                        The EPA also proposed to add a footnote to Table A-1 of part 58, appendix A—Minimum Data Assessment Requirements for NAAQS Related Criteria Pollutant Monitors (88 FR 5669, January 27, 2023). The proposed footnote clarifies the allowable time (

                         every two weeks, once a month, once a quarter, once every six months, or distributed over all four quarters depending on the check) between checks and encourages monitoring organizations to perform data assessments at regular intervals. The EPA received two comments regarding this proposed footnote. One commenter indicated that this change is inconsistent with the QA Handbook for Air Pollution Measurement Systems: “Volume II: Ambient Air Quality Monitoring Program QA Handbook.” The EPA agrees with the commenter; because the QA Handbook is guidance, 
                        <PRTPAGE P="16348"/>
                        the EPA will revise it after this action is finalized to be consistent with the updated CFR provision. Another commenter does not support the addition of the footnote due to concerns about limiting flexibility. In response, the EPA reiterates that the proposed revision is intended to clarify intent and does not make any changes to the required frequencies or acceptance criteria for data assessment. A “weight of evidence” narrative is still found in 40 CFR part 58, appendix A, section 1.2.3. As a result of the comments received and the rationale discussed above, the EPA is finalizing the addition of the new footnote to Table A-1 of part 58, appendix A—Minimum Data Assessment Requirements for NAAQS Related Criteria Pollutant Monitors as proposed.

                         The current total bias goal is an upper 90 percent confidence limit for the coefficient of variation (CV) of 10 percent and ±10 percent for total bias. The EPA's intent was to investigate if this goal is still realistic given updated precision and bias statistics. The EPA received one comment that bias reevaluation may be premature, since the final NAAQS standard had not yet been determined at the time of the proposal. The EPA acknowledges this comment but clarifies that the proposed new bias statistic was evaluated at a range of levels including the proposed range of PM

The EPA proposed to revise appendix B to clarify that in order to participate in the Ambient Air PGVP, producers of Protocol Gases must adhere to the requirements of 40 CFR 75.21(g), and only regulatory ambient air monitoring programs may submit cylinders for assay verification to the EPA Ambient Air PGVP. The EPA received comments in support of and in opposition to this proposed revision. The commenter opposing the revision indicated that the proposed PGVP requirements would be additional and is concerned with an increased resource burden. However, the EPA disagrees with the commenter because that the proposed PGVP requirements are consistent with the existing PGVP requirements in 40 CFR 75.21(g). PGVP has been defined as a regulatory requirement since 2016 (81 FR 17263, March 28, 2016), so the proposed part 58 changes are not “additional” to existing regulations. After consideration of the comments, the EPA is finalizing the update and clarification of ambient air monitoring requirements found in appendix B, section 2.6.1 pertaining to EPA Protocol Gas standards used for ambient air monitoring and the Ambient Air PGVP as proposed.</P>

                        . The commenter also indicated that the MDL “typically has minimal value per the definition of the MDL.” 40 CFR part 50, appendix L states, “The lower detection limit of the mass concentration measurement range is estimated to be approximately 2 μg/m

                         (88 FR 5707, January 27, 2023). These new statistics are designed to address the high imprecision values that result from using these calculations to compare low concentrations that are now more routinely observed in the networks. The EPA received several comments in support of this change in general, but a couple commenters indicated that there could be an error in the new calculation that resulted in high imprecision from the calculation of the equation. The EPA reviewed the technical memorandum and discovered that a multiplier of 100 was unintentionally left in the proposed relative difference equation, Equation 6. Also, equation 6 was corrected from a normalized percent difference to a normalized relative percent difference that is appropriate for comparing collocated pairs at low concentrations.

                         (88 FR 5668-59, January 27, 2023). Because average ambient PM concentrations across the nation have steadily declined since the promulgation of the PM

The EPA received two comments regarding this proposal. One commenter indicated that this change is inconsistent with the QA Handbook. The EPA agrees with the commenter; because the QA Handbook is guidance, the EPA will revise it after this action is finalized to be consistent with the updated CFR provision. Another commenter does not support the addition of the footnote due to concerns about limiting flexibility. In response, the EPA reiterates that the proposed revision is intended to clarify intent and does not make any changes to the required frequencies or acceptance criteria for data assessment. A “weight of evidence” narrative is still found in 40 CFR part 58, appendix B, section 1.2.3. As a result of the comments received and the rationale discussed above, the EPA is adding the new footnote to Table B-1 of part 58, appendix B—Minimum Data Assessment Requirements for NAAQS Related Criteria Pollutant PSD Monitors as proposed.

                    <P>
                        The EPA proposed to remove provisions for approval and use of Approved Regional Methods (ARMs) throughout parts 50 and 58 of the CFR (88 FR 5669, January 27, 2023). ARMs are continuous PM
                        <E T="52">2.5</E>
                         methods that have been approved specifically within a State or local air agency monitoring network for purposes of comparison to the NAAQS and to meet other monitoring objectives. Currently, there are no approved ARMs. There are, however, more than a dozen approved Federal Equivalent Methods (FEMs) for PM
                        <E T="52">2.5</E>
                        . These approved FEMs are eligible for comparison to the NAAQS and to meet other monitoring objectives.
                    </P>
                    <P>The EPA received comments from multiple State air programs in support of the proposal to remove provisions for approval and use of ARMs. One commenter cites that there are multiple FEMs available for monitoring agencies to work with and that the agency was never able to get a candidate ARM to meet the requirements for approval. With the availability of multiple FEMs that now work in the monitoring agency's network, the commenting agency does not anticipate the need to ever pursue an ARM in the future and, therefore, suggests that the ARM provision is no longer needed. Another commenter strongly supported the proposed changes to remove the ARM provisions. The EPA also received comments from a few agencies that supported retaining the ARM provisions instead. One commenter cited the need to consider the rapid advancement of various new technologies and that, in some cases, approved continuous FEMs may have shortcomings, meaning that losing the ability to propose an ARM in the future may limit useful alternative options to monitoring agencies. Another commenter suggested that the removal of the ARM would take away the ability and right to use locally derived correction factors.</P>
                    <P>
                        After considering the comments for and against removing the provisions for ARMs, the EPA believes it is most appropriate to remove the ARM provisions. As described in the proposal, when the EPA first proposed the process for approving and using ARMs, there were no continuous FEMs approved. There are now over a dozen approved PM
                        <E T="52">2.5</E>
                         continuous FEMs and no approved ARMs. Therefore, the EPA is finalizing the removal of ARMs throughout 40 CFR parts 50 and 58 as proposed.

                    <P>
                        The EPA proposed to modify its specifications for PM FEMs in appendix C to Part 58 (88 FR 5670-73, January 27, 2023). Specifically, the EPA proposed that valid State, local, and Tribal (SLT) air monitoring data from Federal Reference Methods (FRMs) generated in routine networks and submitted to the EPA may be used to improve the PM concentration measurement performance of approved FEMs. This approach, initiated by instrument manufacturers, would be implemented as a national solution in factory calibrations of approved FEMs through a firmware update. This could apply to any PM FEM methods (
                        <E T="03">i.e.,</E>
                         PM

                    <P>
                        The EPA proposed this modification because there are some approved PM FEMs that are not currently meeting bias measurement quality objectives (MQOs) when evaluating data nationally as described in the 2022 PA (U.S. EPA, 2022b, section 2.2.3.1), meaning that an update to factory calibrations may be appropriate; however, there is no clearly defined process to update the calibration of FEMs. While there are several types of data available to use as the reference for such updates (
                        <E T="03">e.g.,</E>
                         routinely operated FRMs, audit program FRMs, and chemical speciation sampler 
                        <PRTPAGE P="16351"/>
                        data), we proposed to use routinely operated SLT FRMs as the basis of comparison upon which to calibrate FEMs. The goal of updating factory calibrations would be to increase the number of routinely operating FEMs meeting bias MQOs across the networks in which they are operated. While there are other approaches that could improve data comparability between PM FEMs and collocated FRMs, the EPA believes that the proposed modification to calibrate PM FEMs represents the most reliable approach to update FEM factory calibrations, since the existing FRM network data that meet MQOs would be used to set updated factory calibrations.
                    </P>
                    <P>
                        While the Agency proposed to add this language to more expressly define a process to update factory calibrations of approved PM FEMs, the EPA believes that the existing rules for updating approved FRMs and FEMs found at 40 CFR 53.14 may also continue to be utilized for this purpose, as appropriate. 40 CFR 53.14 allows instrument manufactures to submit to the EPA a “Modification of a reference or equivalent method.” Submitting a modification request may be appropriate to ensure an approved FEM continues to meet 40 CFR 53.9, “Conditions of designation.” Specifically, 40 CFR 53.9(c) requires that, “Any analyzer, PM
                        <E T="52">10</E>

                    <P>
                        There are several technical components to EPA's proposed modification, including: the reference data to be used in the calibrations; implementing as a national solution in factory calibrations of approved FEMs through firmware updates; application to any PM FEM methods (

                        <E T="03">e.g.,</E>
                         during certification of data and 5-year assessments; the EPA's recognition that only data from existing operating sites is available; and finally, that an updated factory calibration does not have to work with the original field study data submitted that led to the original FEM designation.

                        With the proposed modification, the EPA solicited input on these technical issues as well as the overall approach and any alternatives that could lead to more sites meeting the bias MQO with automated FEMs, especially for those sites that are near the level of the primary annual PM
                        <E T="52">2.5</E>
                         NAAQS, as proposed to be revised in section II above. In response, the EPA received comments from about two dozen entities, most of which were SLT air programs or Multi-Jurisdictional Organizations (MJOs) comprised of these entities.
                    </P>
                    <P>Overall, there was broad and strong support from a majority of commenters for the proposed requirement to use FRM data generated in routine networks and submitted to the EPA to update factory calibrations included as part of approved FEMs. There were a smaller number of critical comments on the proposed process as well as some commentors that supported the proposed requirement but also provided additional suggestions for the EPA's consideration. Below, we address each of the areas on which the EPA requested comment regarding the calibration of PM FEMs, as well as a few additional areas where multiple commenters offered input on other areas related to our proposal.</P>
                    <P>
                        A majority of the commenters on the proposed PM FEM calibration process support the process to use valid State, local, and Tribal FRM data generated in routine networks and submitted to the EPA to improve the PM concentration measurement performance of approved FEMs. Some commenters suggested that this action is needed to ensure that data reported from FRMs and FEMs are comparable and correction methods applied to data from FEM monitors are defensible across the national PM monitoring network. Others stated that they agree with the EPA that this is a critical step in the right direction to account for the discrepancies between PM
                        <E T="52">2.5</E>
                         FRM data and PM
                        <E T="52">2.5</E>
                         FEM data. Some commented that applying corrections includes a recognition that, while different measurement principles may produce differences in the resulting data, having an approach that minimizes bias is extremely important. Finally, some stated their belief that a correction factor is necessary to preserve data integrity with the FRM.
                    </P>
                    <P>The EPA also received comments suggesting ways that the PM FEM correction could be performed, including through detailed analysis of data; by having PM FEM instrument manufacturers evaluate nationally available valid FRM data to update factory calibrations; and, by having the instrument manufacturers implement calibration adjustments at the factory.</P>
                    <P>
                        The EPA also received supportive comments on the PM FEMs calibration relating to comparability to the NAAQS. For example, a commenter stated that it is important to ensure bias MQOs are met for FEMs run at sites potentially affected by revised standards as well as the need to accurately designate areas as attaining or not attaining the NAAQS. There were comments supporting the correction of PM FEM data as helping the EPA and SLT monitoring programs continue to evolve toward more automated methods. For example, one commenter appreciates the EPA's support for the ongoing move from filter-based PM
                        <E T="52">2.5</E>
                         FRMs to use of continuous FEMs, stating that they concur with the EPA's assessment that there is monitoring bias between FRMs and FEMs, and commending EPA for recognizing ongoing data quality issues for FEMs and for taking action to improve these issues in collaboration with instrument manufacturers and SLT agencies.
                    </P>
                    <P>
                        A small number of commenters were critical of the proposed FEM calibration approach. One commenter noted that EPA should further examine the handling of FEM PM
                        <E T="52">2.5</E>
                         data when used for comparison to the NAAQS. In response, we note that monitoring agencies and the EPA will continue to examine the comparability and use of FEM data used in comparison to the NAAQS. Another commenter suggested that the calibration process for a designated PM monitor should not be altered following Class III designation approval. The EPA disagrees as we believe it is appropriate for FEMs to be calibrated with routinely operated FRMs, because doing so is an efficient way to work towards FEM data meeting the bias MQO across the networks in which the FEMs are currently being operated. Also, having continuous PM FEMs meeting bias MQOs allows the use of the data in a variety of other ways that manually operated FRMs samplers cannot support. Another commenter stated that, if a particular FEM designated make or model of 
                        <PRTPAGE P="16352"/>
                        instruments fails to meet MQOs, then that make or model should be removed from the designations altogether. The EPA agrees and clarifies that the modification would not prevent removal of FEM designation from a make or model of instrument under the existing 40 CFR 53.11—Cancellation of reference or equivalent method designation. This may be appropriate if there are no other solutions to improve the method such that it achieves bias MQOs.

                    <P>
                        A few commenters provided specific recommendations for how the regulatory language could be improved. These included comments that the new regulatory language proposed for 40 CFR part 58, appendix C, section 2.2 must ensure consistency and transparency when requesting changes to the factory calibration; that the EPA should incorporate binding regulatory language in 40 CFR part 58, appendix C, section 2.2 (
                        <E T="03">i.e.,</E>
                         it currently lacks “shall” or “must”) to ensure the language is not open to inconsistency and does not provide unique deference to instrument manufacturers without a mechanism for transparent communication of the changes being made and the supporting technical analysis. A commenter also requested that the EPA define the core requirements needed to ensure all requests for updating factory calibrations are required to follow the same process, using data of the same known quality, and evaluating the effectiveness of the resulting correction factors consistently.
                    </P>
                    <P>In response to these comments, while the EPA agrees that the proposed regulatory language for 40 CFR part 58, appendix C, section 2.2 must ensure consistency and transparency when entities request changes to factory calibrations, the EPA disagrees that the regulations cannot also provide some flexibility. For example, we believe that a degree of flexibility is appropriate regarding whether outliers in the data to be used for factory calibration should or should not be included, the range of data to be included, and in utilizing collocated FRM and FEM data for updated calibrations from a representative set of geographic areas in which it is produced. The EPA believes that the proposal defined the core requirements needed to ensure all requests for updating FEM factory calibrations will follow the same process, using data of the same known quality and evaluating the effectiveness of the resulting correction factors consistently.</P>
                    <P>
                        In its proposal, the EPA identified that while there are several types of data available to use as the reference for FEM calibration updates, including data from routinely operated FRMs, audit program FRMs, and PM
                        <E T="52">2.5</E>
                         chemical speciation samplers, the EPA proposed to use routinely operated State, local, and Tribal FRMs as the basis of comparison upon which to calibrate FEMs (88 FR 5670-71, January 27, 2023). Importantly, routine SLT agency FRM data form the largest portion of the monitored air quality data used in epidemiologic studies that are being used to inform proposed decisions regarding the adequacy of the public health protection afforded by the primary PM
                        <E T="52">2.5</E>
                         NAAQS, as discussed in section II above.
                    </P>
                    <P>Overall, there was broad and strong support for utilizing collocated FRM data from routine SLT networks to provide calibrations of the continuous FEMs. For example, several commenters agree that valid SLT air monitoring data generated in routine networks and submitted to the EPA will improve the PM concentration measurement performance of approved FEMs. Another commenter provided support for PM FEM instrument manufacturers to evaluate nationally available valid FRM data as well as other data sets such as the performance evaluation audit program to update factory calibrations. The EPA believes that the routinely operated PM FRMs represent the best and largest source of data to calibrate continuous PM FEMs, and that performance evaluation audit program data should be kept independent of the calibration process. This will mean that assessments of the routine monitoring operations, including both the FRM and any future updated PM FEMs, will appropriately remain independent in evaluating whether updated methods are meeting bias MQOs. The EPA is, therefore, finalizing its approach to use routinely operated SLT FRMs as the basis of comparison upon which to calibrate continuous PM FEMs as proposed.</P>
                    <P>Regarding the EPA's proposed requirement to utilize factory calibrations (88 FR 5670-71, January 27, 2023), several commenters agreed that factory calibrations provide the best option to improve PM FEMs. For example, one commenter stated that the correction factors are necessary to preserve data integrity with the FRM, and they support the proposal that the approach be initiated by instrument manufacturers and implemented as a national solution through firmware updates.</P>
                    <P>Regarding the proposed requirement that calibrations be initiated by instrument manufacturers (88 FR 5671, January 27, 2023), most commenters were supportive of the proposed approach that recalibration of FEM PM instruments be initiated by instrument manufacturers. For example, one commenter stated they support allowing instrument companies submit improvements to their existing FEMs, as vendors should be encouraged to improve their methods. Another commenter noted that having a methodology initiated by the manufacturer will have nationwide consistency. A few of commenters recommended that SLT air agencies should have the additional ability to petition the EPA Administrator to initiate factory calibrations of FEMs to better meet MQOs when data collected by their agencies indicate disparities, because the monitoring agencies are responsible for the quality of the data from the specific makes and models of instrumentation used in their networks. While the EPA believes that, in most cases, the instrument companies should be the ones to initiate the process for calibration of FEMs to routinely operated FRMs, we agree with the commenters who suggested that other options should be available, including allowing monitoring agencies or MJOs to work independently or together to pursue improvements to designated FEMs. However, the EPA believes that any such improvements initiated by monitoring agencies or MJOs should still be facilitated through the responsible instrument company. Also, any such effort to improve data quality should be employed across all the networks in which the methods are operated and not limited to the networks operated by the agency(s) pursuing such improvements.</P>
                    <P>
                        Regarding how frequently factory calibrations should be updated, our proposal identified that it would be most appropriate to not define a specific time period for updates; rather, updates should be based on whether or not quality data is being produced across a given network (88 FR 5672, January 27, 2023). Regarding this issue, one commenter recommended that instrument manufacturers be required to evaluate and, if necessary, adjust PM FEMs factory calibrations on an ongoing basis at regular intervals. The EPA notes that while it does not have the authority to require instrument companies to evaluate the quality of data from operating FEMs under 40 CFR part 58, the EPA does routinely participate in conferences and workshops and makes assessments of data quality specific to instrument makes and models publicly available. The EPA also regularly summarizes relevant FRM and FEM data 
                        <PRTPAGE P="16353"/>
                        quality in documents such as the 2022 PA (U.S. EPA, 2022b). Therefore, consistent with the proposal, we are not finalizing any specifics regarding how frequently factory calibrations should be updated but commit to continue to routinely provide information to SLT agencies regarding FEM data quality.

                    <P>
                        The EPA proposed that the calibration of FEMs could apply to any of the PM FEM method indicators (
                        <E T="03">i.e.,</E>
                         PM
                        <E T="52">10</E>
                        , PM
                        <E T="52">2.5</E>
                        , and PM
                        <E T="52">10-2.5</E>
                        ) (88 FR 5670, January 27, 2023). The EPA received only supportive comments. All comments that included a discussion of three PM metrics support their inclusion for calibration of PM FEMs. Therefore, the EPA is finalizing the inclusion of all three PM indicators (
                        <E T="03">i.e.,</E>
                         PM
                        <E T="52">10</E>
                        , PM
                        <E T="52">2.5</E>
                        , and PM
                        <E T="52">10-2.5</E>
                        ) as proposed.
                    </P>
                    <P>The EPA proposed that either all data available or a range of data up to 125% of the 24-hour NAAQS for the PM indicator of interest may be used to establish new factory calibrations, (88 FR 5671-73, January 27, 2023). The EPA received many comments supportive of the proposal and one comment offering a different approach on the range of data to use. One commenter recommends that the EPA should consider using all “validated” data because how these instruments behave under normal operating ranges may be just as important as how they behave when monitoring conditions are low or elevated, and that the full range of data should be used when determining the appropriate level of the standard, just as the full range of data is used in determining if an area is attaining the standard. In response to this comment, the EPA believes that making allowances for some flexibilities will increase the likelihood of instrument companies pursuing such improvements. Also, even though there is flexibility, the EPA will still be able to evaluate the appropriateness of a range of concentration data included as part of each application submitted. Also, the EPA notes that in certain circumstances, States do petition the EPA to set aside data under the Exceptional Events Rule (§ 50.14, “Treatment of air quality monitoring data influenced by exceptional events”). Where approved, exceptional event data are set aside from use in regulatory decisions. Thus, there is a process to set aside certain high concentration data for certain purposes. Therefore, the EPA is finalizing the provision that factory calibrations may be based on a range of valid data as proposed.</P>
                    <P>The EPA solicited comment on the representative set of geographic locations to use in the calibration of FEMs compared to collocated FEMs (88 FR 5671, January 27, 2023). Most commenters were supportive of the approach of using representative sites in SLT networks from across the country. For example, several commenters provided their support for PM FEM instrument manufacturers to evaluate nationally available valid FRM data to update factory calibrations. Commenters disagreeing with a national geographic approach preferred to allow local solutions to correct data. For example, one commenter suggested having a local or regional option because PM instruments are impacted by, and respond differently to, a variety of local factors, including relative humidity, temperature, concentration levels, and particle composition. The EPA agrees that there are challenges in the response of PM FEMs to a variety of local factors; however, this can be true of many methods and are not specific to PM FEMs and, therefore, does not provide a reason to reject this approach in this instance. Another commenter stated that the proposed national correction factor is a “flawed concept,” suggesting that it is “widely understood throughout the monitoring community that monitors perform best with a local correction factor.” This commentor offered no record or citation supporting this point. The EPA counters that while monitoring agencies may statistically correct data from a PM continuous monitor for AQI purposes (40 CFR part 58, appendix G), there are both examples of well performing statistically corrected PM continuous monitors being used for AQI purposes; however, without proper attention and updates, there are also examples of poorly performing ones. Finally, another commenter believes that a national correction factor cannot possibly incorporate data to represent all the scenarios across the nation that have an impact on monitor performance and data quality. Although the EPA agrees that there are a variety of local scenarios that could affect monitor performance, the overall benefits of having nationally consistent measurement of PM concentrations and national calibration of data outweigh the potential advantages of locally specific calibrations.</P>
                    <P>Several commenters also disagreed with using local and regional calibrations of data, including some monitoring agencies that asserted being unable to reinvest in the operation of FRMs that would be required to locally calibrate their own PM FEMs. Further, every approved PM FEM method designated today is effectively calibrated through demonstration of field testing in the areas in which it was required to be tested (40 CFR 53.35(b)(1)). Moreover, the EPA proposed to require instrument manufacturers to demonstrate that they can improve the number of sites meeting bias MQOs by initiating a recalibration of an FEM. Thus, the use of a national set of sites where the methods are operated is essentially a fine-tuning of the PM FEMs performance across all sites where it is used.</P>
                    <P>After considering all the comments received, the EPA believes it is appropriate to finalize as proposed with a representative set geographic locations at SLT sites to calibrate PM FEMs. Identification of such sites would be made by the applicant of the planned updated calibration, subject to EPA approval, and submitted to the EPA in accordance with the requirements and application instructions in 40 CFR part 58, appendix C, sections 2.2 and 2.7. The EPA encourages early communication between an applicant seeking a method update and the EPA to facilitate the most appropriate sites are included in any updated application of the methods calibration.</P>
                    <P>
                        The EPA proposed that instrument companies may, but are not required to, check for and exclude any potential outliers that may exist in the validated State, local, and Tribal agency network data available from AQS that would be used to establish new factory calibrations. The EPA received two comments regarding potential outlier approaches. One commenter disagreed with the proposed approach and instead recommended the use of all “validated” data, because how these instruments behave under normal operating ranges may be just as important as how they behave when monitoring conditions are low or elevated. The EPA acknowledges this point; however, the proposal on outliers allows flexibility in using standard outlier tests if needed to include or exclude such data as part of the calibration process. Ultimately, the true test of success for an updated method calibration will be that a higher number of sites are meeting bias MQOs in the areas in which the method is used, which will include all routine valid data including any potential outliers. Another commenter asserted concerns with the ability of instrument manufacturers to analyze data within individual monitoring agencies. The EPA disagrees with the commenter because decisions whether to include or exclude outliers should be flexible and made on a case-by-case basis. Moreover, the expected substantially larger dataset from routinely operated collocated FRMs and FEMs compared to what was 
                        <PRTPAGE P="16354"/>
                        used in the original FEM designation testing (§ 53.35 Test procedure for Class II and Class III methods for PM
                        <E T="52">2.5</E>
                         and PM

                        ) will minimize the effect of any potential outliers.
                    </P>
                    <P>In contrast to these two comments, the EPA received many comments supportive of the proposed outlier approach overall. Therefore, the EPA is finalizing this part of the proposal that instrument companies may, but are not required to, check for and exclude any potential outliers that may exist in the validated State, local, and Tribal agency network data available from AQS that would be used to establish new factory calibrations.</P>
                    <P>Several commenters offered input on statistical criteria and initial testing requirements for approval of candidate PM FEMs and the role of instrument manufacturers in this process. The EPA did not propose any changes related to these issues; however, these comments have been considered below.</P>
                    <P>
                        One commenter suggested that data quality objectives, bias, and precision estimators for different monitoring methods should be based on averages at both national and regional levels for purposes of comparison. Another commenter asked to strengthen the criteria for Class 3 Equivalency standards for candidate PM instrumentation. On testing requirements, one commenter recommended that the EPA consider updating the 40 CFR part 53 process for approving FEMs so that the testing process more closely reflects the regulatory deployment and data handling that generates NAAQS-comparable data. Another commenter asked that the results from “summer” and “winter” field evaluations not be averaged together because it allows agencies to minimize the error of biased instruments by averaging poor results with data often biased in the other direction. The same commenter also recommended that candidate instruments data sets should not be averaged together as is done currently where data from triplicate instruments are averaged for each day. Another commenter asked that the EPA require FEM field comparability tests in the northwest (
                        <E T="03">e.g.,</E>
                         in EPA Region 10) in areas where particulate derived from biomass predominates to ensure that certified instruments will perform reliably in regions influenced by these sources. Related to the different measurement principles and the instrument companies' role in PM FEMs, one commenter noted that FEMs may never align perfectly with the FRMs due to the use of different measurement principles. Another commenter asked that manufacturers of FEM instruments be held accountable for ensuring that they continue to meet FEM criteria, whether through calibration updates and/or follow-up evaluations. Another commenter suggested that instrument manufacturers should be required to further evaluate the FEM monitoring data at defined intervals including, but not limited to, the 2-year and 5-year approval anniversaries.

                    <P>
                        The EPA did not propose to make modifications to the statistical criteria or testing requirements; however, we did solicit comment on any alternatives that would lead to more sites meeting the bias MQO with automated FEMs, especially for those sites that are near the level of the primary annual PM
                        <E T="52">2.5</E>
                         NAAQS as proposed (88 FR 5672-73, January 27, 2023). While the comments requesting that the statistical criteria be strengthened may have merit, doing so would not address the large inventory of already deployed PM FEMs used throughout the country. Also, without performing a detailed Data Quality Objective (DQO) design process, it is unclear how changing one or more statistical criteria would help improve the number of sites meeting the bias MQO now or in the future. Similarly, while the comments asking for changes to the locations of testing may also have merit, the EPA believes this could be a deterrent for instrument manufactures to seek additional improvements since more testing would be required, at least for candidate methods. Regarding the comment on the different measurement principles, the EPA concurs that different measurement principles may never align perfectly. Also, the EPA notes that the Agency has longstanding goals for acceptable measurement uncertainty of automated and manual PM
                        <E T="52">2.5</E>
                         methods in 40 CFR part 58, appendix A, section 2.3.1.1. Therefore, while having different measurement principles align is useful, meeting the goal for acceptable measurement uncertainty is the objective.

                        Regarding the comments related to the instrument companies' role in PM FEMs, the EPA notes that FEMs are already required to meet 40 CFR 53.9, “Conditions of designation.” Specifically, 40 CFR 53.9(c) requires that, “Any analyzer, PM
                        <E T="52">10</E>

                    </P>
                    <P>In addition to these few recommendations, the EPA received many comments supportive of the proposal that valid State, local, and Tribal air monitoring data from FRMs generated in routine networks and submitted to the EPA may be used to improve the PM concentration measurement performance of approved FEMs; therefore, consistent with the proposal we are not finalizing any updates to the statistical criteria, testing requirements, or requirements on instrument manufactures as proposed.</P>
                    <P>The EPA proposed that any new factory calibration should be developed using data from at least 2 years and tested on a separate year(s) of data (88 FR 5672, January 27, 2023). Comments on this part of the proposal were generally supportive. One commenter requested that at least a 3-year dataset, rather than the proposed 2 years, be used for a representative design value comparison of the FEM and FRM datasets to be evaluated. Another commenter pointed out that as large a data set as possible should be used, but EPA should not limit it to only data collected by instruments that have operated for more than 2 years.</P>
                    <P>In response to these comments, the EPA notes the broad support for the proposal as written. Also, the EPA notes that the 2-year period for using data to develop a factory calibration is a minimum, and that more years may be used as appropriate. Therefore, the EPA is finalizing its approach that any new factory calibration should be developed using data from at least 2 years and tested on a separate year(s) of data as proposed.</P>
                    <P>
                        The EPA proposed several aspects of the FEM calibration on which we did not receive specific comments, including a provision that FEM methods should be evaluated by monitoring agencies as part of routine data assessments, such as during certification of data and 5-year assessments; the fact that the EPA recognizes only data from existing operating sites are available for use in factory calibrations; and recognition that an updated factory calibration does not have to work with the original field study data submitted that led to the designation as an FEM. With the broad general support from commenters summarized above, the EPA is finalizing each of these 
                        <PRTPAGE P="16355"/>
                        individual aspects of the FEM calibration as proposed.
                    </P>
                    <P>In the proposal, the EPA identified that we should expect a lag between the date when an already designated method is approved with a new factory calibration as an updated method by the EPA and when it can be implemented in the field. The EPA solicited comment on how to approach the data produced during this lag. Commenters provided input not only on how to address data during the lag, but also regarding how to address data already collected prior to a method update that has the potential to be used in regulatory decision making, particularly where such collected data do not meet the bias MQO. In response to this solicitation of comment, there was a consistent recommendation that calibrations of data associated with method updates should be applied to all relevant PM data prior to the EPA using it for designations under a final NAAQS.</P>
                    <P>While the EPA appreciates these comments and recognizes their support for retroactive data correction, at this time and following this final rule, monitoring agencies should continue to report PM FEM data as measured. This component of this final rule is focused only on revising 40 CFR part 53, appendix C to implement an updated calibration for approved PM FEMs. The issue of how prior and future monitoring data will be used in the implementation of this NAAQS, such as for designations, and for air quality regulatory programs is outside the scope of this rulemaking and will therefore be addressed by the EPA in a subsequent relevant action or actions.</P>
                    <P>The EPA received comments on whether updates to PM FEM methods should be required to be implemented or there would flexibility in when and if a monitoring agency implemented them. The commenters asked that EPA be flexible in allowing the use of updated method correction factors intended to improve the data comparability between the FRMs and FEMs.</P>
                    <P>In most cases, the EPA expects that updating the FEMs will result in improved data quality and more sites meeting bias MQOs; however, the EPA is not finalizing an update requirement in this action. Monitoring agencies can assess their data and make decisions on an update based on whether they are meeting the bias MQOs. Such decisions on whether or not to update a method may efficiently be included in those agencies' annual monitoring network plans under 40 CFR 58.10, “Annual monitoring network plan and periodic assessment,” which are already subject to EPA Regional office approval. In some circumstances, it is possible the original PM FEM may be revised in a manner where only the updated method has an active approved designation. In these cases, monitoring agencies would need to address updating their PM FEM in a timely manner.</P>
                    <P>
                        The EPA solicited input on any alternative approaches that could lead to more sites meeting the bias MQO with automated PM FEMs, especially for those sites that are near the level of the primary annual PM
                        <E T="52">2.5</E>
                         NAAQS as proposed to be revised in section II above. A few commentors provided input on potential options for alternative approaches and several others offered input on how a local or regional calibration of an FEM could work. Among alternative approaches, one commenter suggested that manufacturers of FEMs could provide settings that would allow for adjustments to make FEM data more “FRM-like.” Another commenter suggested working with the manufacturers of FEM equipment to diagnose the cause of the bias and then to address it appropriately.

                        The EPA received several comments on how to implement a local or regional calibration of FEMs. One commenter suggested that EPA could allow for SLT agencies to adjust FEM data to be more “FRM-like” prior to submitting data to AQS. Another commenter suggested using a rolling 3-month linear regression based on a comparison of FEM data to PM
                        <E T="52">2.5</E>
                         levels measured by a 1-in-6-day FRM. Another commenter recommended that the EPA allow the application of a correction factor that is from an area with a similar climate and other conditions. Another commenter suggested that, for metropolitan statistical areas (MSAs) where the re-calibrated FEMs still do not meet equivalency criteria, monitoring agencies should be able to use the rolling linear regression technique to further calibrate the FEMs within an MSA. Another commenter suggested that developing a simple linear regression could establish the relationship between FEM data and FRM data and be used to adjust the FEM data at each site where they are collocated. Another commenter suggested that averaging the results within a MSA and applying it on an MSA basis with the previous 2 years of data could provide an adjustment method for sites without a collocated FRM. Another commenter identified that a regional correction factor potentially could improve instrument accuracy to biomass sources, which are a large component of PM in many communities.
                    </P>
                    <P>Among the alternative approaches suggested, having settings that would allow for adjustments to make FEM data more “FRM-like” has merit, but assuming this was within a PM FEM itself, it would need to be separately incorporated into each make and model of FEM. If EPA were to pursue this alternative approach, the suggestion could be incorporated into a future regulatory action as a potential condition of designation because, without having the opportunity to thoughtfully consider how every step of such an approach would need to work, including what such requirements would look like and how potential settings adjustments would be made, it is not appropriate for the EPA to require the availability of such settings now, nor would it address the inventory of currently available PM FEMs already operating.</P>
                    <P>Regarding the suggestion that the EPA and SLTs should work with the manufacturers of FEM equipment to diagnose the cause of any biases and then to address them appropriately, the EPA supports this recommendation, but does not believe a regulatory change is required to allow the monitoring community (EPA and SLTs) to work with instrument manufacturers in this way.</P>
                    <P>
                        Regarding the several comments on how to implement a local or regional calibration of FEMs, the EPA acknowledges the desire for this flexibility but believes that any such provisions for local or regional calibration of FEMs would need to be thoroughly thought out and proposed for consideration across the monitoring community. While several commenters support such an approach, the EPA also received adverse comments on the potential for local and regional calibration of PM FEMs instead of national. Most of the criticism of local and regional calibration of PM FEMs centered on both the lack of existing operating PM FRMs in commenters' networks and monitoring agencies' inability to staff the higher number of operating FRMs that would have to be collocated with PM FEMs to calibrate. Thus, the commenters that oppose local and regional calibrations of data prefer to utilize the national calibration of FEM data as proposed. Acknowledging all of these viewpoints, the EPA believes that it would not be appropriate to institute such an approach at this time. As discussed throughout this section, this final rule, the EPA is embarking on a new national approach to calibration of FEMs where valid State, local, and

                        Tribal air monitoring data from FRMs generated in routine networks and submitted to the EPA may be used to improve the PM concentration measurement performance of approved FEMs. The EPA and the community of SLT monitoring agencies can further consider other solutions to improving PM FEM methods, including local and regional scale calibration of FEMs, in a future review of the PM NAAQS.

                        In summary, the EPA is finalizing its proposal to allow valid State, local, and Tribal air monitoring data from PM FRMs and FEMs generated in routine networks and submitted to the EPA to update factory calibrations included as part of approved FEMs (40 CFR part 58, appendix C, sections 2.2 and 2.7). This approach, which will typically be initiated by instrument manufacturers but can also be spurred by monitoring agencies, MJOs of monitoring agencies, and the EPA itself, is to be implemented as a national solution in factory calibrations of approved FEMs through a firmware update, subject to EPA approval. FEM calibrations can apply to any PM FEM methods (

                        ). As part of this process, the EPA is finalizing that a range of data based on the most representative concentrations up to all available concentrations may be used in developing and testing a new factory calibration; that a representative set of geographic locations can be used; that outliers may be included or not included; that a new factory calibration should be developed using data from at least 2 years and tested on a separate year(s) of data; that updates to factory calibrations can occur as often as needed and should be evaluated by monitoring agencies as part of routine data assessments such as during certification of data and 5-year assessments; that the EPA recognizes only data from existing operating sites is available; and that an updated factory calibration does not have to work with the original field study data submitted that led to the designation as an FEM. The EPA is finalizing this approach as proposed with the intention of having more sites meet the bias MQOs with automated PM FEMs.

Specifically, the EPA proposed to modify the existing requirement at 40 CFR part 58, appendix D, section 4.7.1(b)(3)): “For areas with additional required SLAMS, a monitoring station is to be sited in an area of poor air quality,” to additionally address at-risk communities with a focus on anticipated exposures from local sources of emissions.

                         exposures to sources of concern. Commenters included State, local, and Tribal air agencies and multijurisdictional organizations (MJOs) comprised of those agencies; industry and industry groups; other Federal, State, and local government entities; public health, medical, and environmental nongovernmental organizations (NGOs); and private citizens. The EPA proposed to require that sites located in at-risk communities (particularly those whose air quality is potentially affected by local sources of concern) should nonetheless meet the requirements to be considered representative of “areawide” air quality as this is consistent with all other minimally required sites. There were several other technical components of the proposed requirement for which we asked for comment, including: how to identify at-risk communities; the PM sources of concern important to consider; the datasets that can be used to identify communities with high exposures; the most useful measurement methods to collocate with PM
                        <E T="52">2.5</E>

                         exposures to sources of concern. A few commenters offered detailed supporting comments. For example, one commenter recommended targeting investment in regulatory monitors in EJ communities, opining that there is presently a lack of equitable distribution of these monitors in low-income and minority communities. Another commenter supports the inclusion of an EJ factor in PM
                        <E T="52">2.5</E>
                         monitoring network design criteria as a means to assess whether disparities in exposure are reduced in the future. The EPA appreciates the support for the proposed requirement and acknowledges the desirability of a goal to assess if disparities in exposure are reduced in the future as a result of these monitoring efforts.
                    </P>
                    <P>
                        Some commenters were generally supportive of the proposed requirement but suggested that the EPA should recast the approach in a more specific way or offered additional examples of sources of concern. For example, one commenter stated that PM
                        <E T="52">2.5</E>
                         emissions from residential and commercial wood burning result in localized hotspots that are often not revealed by community air monitoring. Another commenter asked that the EPA adopt a strategy to monitor EJ communities near both larger well-known point sources of PM
                        <E T="52">2.5</E>
                         and along traffic corridors as well as smaller sources that, when taken together, may create a large amount of emissions and health harms in the area. Another commenter stated that the national network of monitors operated by the EPA captures data used for generalized modeling, but overall monitoring is not as granular as one would expect, especially in urban areas. For instance, the commenter suggested that EPA could monitor suspected “hot spots” (
                        <E T="03">e.g.,</E>
                         residential development adjacent to highways and active construction sites) to better manage and mitigate PM
                        <E T="52">2.5</E>
                         pollution at their sites of origin, and that more extensive and granular monitoring data would also facilitate essential research and inform future evaluations and adjustments of the NAAQS. The EPA acknowledges these comments identifying other sources of concern, and we address these and other potential sources of concern below.
                    </P>
                    <P>
                        Among adverse comments, a few commenters stated that “at-risk communities” is not well defined. The EPA disagrees and directs those commenters to the numerous places where this definition is covered, including in Section II.B.2 of the proposal where we explained the term related to a variety of at-risk populations (88 FR 5591-92, January 27, 2023) as well as section 12.5 of the 2019 ISA (U.S. EPA, 2019a) and section 3.3.3 of the ISA Supplement (U.S. EPA, 2022a). Other commenters oppose the addition of the proposed monitoring because they feel it would reduce flexibility for agencies in deciding where they should site monitors, advocating that monitoring agencies should be afforded maximum flexibility to identify where to site monitors for at-risk areas. Because the EPA recognizes the challenges cited by these commenters related to establishing new ambient air monitoring stations, the EPA is finalizing the modified requirement on PM
                        <E T="52">2.5</E>
                         monitoring network design criteria intended to address at-risk communities that allows flexibility regarding which EJ communities should be monitored. Finally, one commenter asked that the EPA clarify a specific metric to judge how to site monitors in at-risk communities. Instead, the EPA believes it is appropriate for agencies to recommend what they believe to be the most important things to consider for their sites to meet the PM
                        <E T="52">2.5</E>
                         network design requirements and, thus, applying a new metric could take away from local priorities for at-risk communities.

                    <P>
                        A few commenters asked that the EPA require more monitoring than proposed. One commenter stated that it would be more beneficial to overburdened communities if air monitoring were required in all at-risk communities. A few commenters asked that EPA require additional monitoring for attainment of PM
                        <E T="52">2.5</E>
                         NAAQS in EJ communities. In response to these comments, the EPA supports the SLT agencies' initiatives to conduct additional monitoring beyond the minimum monitoring requirements and network design criteria. In addition, the EPA supports agencies' use of alternative datasets such as sensors and sensors networks, satellites, and other non-regulatory monitoring where appropriate for non-regulatory data uses. The EPA notes that many monitoring agencies already operate more monitoring sites than are minimally required, and we expect this to continue as agencies consider siting monitors in at-risk communities.

                    <P>
                        However, the EPA also received substantial concerns from monitoring agencies about their resource constraints, including staffing to support any potential new monitoring. The EPA also notes that the existing and robust network of almost 1,000 PM
                        <E T="52">2.5</E>
                         sites nationally is designed to continue to protect all populations at the level of the NAAQS discussed in section II of this final action by always having at least one site in the area of expected maximum concentration for each CBSA where monitoring is required. As a result of the revisions to the annual PM
                        <E T="52">2.5</E>
                         NAAQS being finalized in this action, a small number of new monitoring sites will also be required under EPA's current minimum monitoring requirements. With the monitoring network design changes finalized in this rule, many of these existing and new sites will form an important sub-component of the PM
                        <E T="52">2.5</E>
                         network by better characterizing air quality in at-risk communities, particularly with respect to sources of concern.

                    <P>
                        The EPA concludes that the requirements in this final rule for siting of monitoring in at-risk communities will meaningfully improve the PM
                        <E T="52">2.5</E>
                         monitoring network and its characterization of air quality in at-risk communities, without placing substantial new resource burdens on States and their monitoring agencies that would be associated with requirements for additional monitoring sites. Therefore, the EPA is finalizing this part of the proposed action without requiring additional monitoring sites beyond what would be associated with the revised annual PM
                        <E T="52">2.5</E>
                         NAAQS described in section II as they pertain to the minimum requirements associated with Table D-5 of Appendix D to Part 58—PM
                        <E T="52">2.5</E>

                    <P>
                        A few commenters asked that the EPA enhance monitoring in smaller cities and rural areas. One commenter asked for the EPA to extend the proposed monitoring network to Micropolitan Statistical Areas with populations of 10,000-50,000 and to rural areas. Another commenter pointed out that current air quality monitoring networks focus on urban and densely populated areas; therefore, rural areas are often not captured in this existing monitoring infrastructure, despite well-documented examples of high PM concentration in rural communities. The commenter believes this results in inadequate assessment of air pollution exposures for a substantial segment of the U.S. population. The EPA disagrees that there needs to be additional requirements for small CBSA's and rural areas. Regarding these comments, the EPA points out that we have a long-standing requirement for each State to monitor at background and transport sites (40 CFR part 58, appendix D, section 4.7.3—Requirement for PM
                        <E T="52">2.5</E>
                         Background and Transport Sites). Also, if an agency deems it appropriate to do so, monitoring coverage of rural areas can be accomplished with other tools 
                        <PRTPAGE P="16358"/>
                        such as sensors and sensors networks, satellites, and other non-regulatory monitoring. Although there may be short-term high exposures in rural areas, there is no evidence that long-term averages are higher in rural areas compared to urban areas with significantly higher density of populations and emissions. For smaller cities or rural areas that may have concentrations near the level of the PM
                        <E T="52">2.5</E>
                         NAAQS finalized in section II above, monitoring agencies are encouraged to monitor and address emissions as appropriate.

                    <P>
                        Some commenters disagree that the proposed revision to the PM
                        <E T="52">2.5</E>
                         monitoring network design criteria to address at-risk communities is needed. One commenter stated that including an EJ factor is not necessary because the current network is designed to protect all citizens. Another commenter stated that EJ factors could be cumbersome to implement. Another commenter asserted the proposal to add SLAMS in at-risk communities with higher PM
                        <E T="52">2.5</E>
                         concentrations might create more granular data and provide for a greater margin of safety for those communities and monitors in such a way that data from those areas could misrepresent the larger area represented by the network. In response to the comment on the current network protecting all citizens, the EPA agrees that by measuring in the community with the highest concentration of PM
                        <E T="52">2.5</E>
                         we protect other citizens; however, as stated in the proposal, the EPA believes that adding a requirement for sites with an EJ factor near sources of concern will enhance the overall network to the benefit of all citizens. Also, we anticipate that with the more protective annual NAAQS finalized in section II above, characterizing localized air quality issues will become even more important around local emission sources. As for EJ factors being cumbersome to implement, the EPA disagrees because there are many such locations already operating successfully in the current network. Regarding the comment that sites in at-risk communities may misrepresent the larger area represented by a particular network, the EPA notes that pursuant to 40 CFR part 58, minimally required sites in a given network are to represent area-wide air quality; therefore, sites in at-risk communities, by definition, would be representative of the communities within the network in which they are sited for the level of protection intended under the annual PM

                        In the proposal, the EPA identified that, in light of the evidence of increased risk to at-risk communities, it would be appropriate to better characterize exposures for communities in proximity to local sources of concern (88 FR 5673-76, January 27, 2023). Thus, the EPA proposed that enhanced networks should include representation of at-risk communities living near emission sources of concern (
                        <E T="03">e.g.,</E>
                         major ports, rail yards, airports, industrial areas, or major transportation corridors). The EPA requested comment on the types of sources of concern most important to consider. In addition to supporting the types of sources the EPA identified in the proposal, commenters also identified several additional localized sources such as railroads, stationary sources, transportation facilities, and communities with high numbers of wood stoves. 
                    </P>
                    <P>
                        A few commenters suggested the inclusion of sources that are often considered line and/or area sources, 
                        <E T="03">e.g.,</E>
                         traffic corridors and emissions from federally regulated facilities, military installations, and national forests. Commenters also identified other sources usually associated with long-range transport such as smoke from wildfire and prescribed fires and long-distance transport of PM, for example from Saharan dust and other international transport. As explained in the proposal, the site with the highest expected PM
                        <E T="52">2.5</E>
                         is already required to have a monitor by our long-standing requirement that monitors be placed “. . . in the area of expected maximum concentration” (§ 58.1 and appendix D, section 4.7.1(b)(1)). The EPA expects that both sites with the expected maximum concentration and sites specifically placed in at-risk communities would be impacted by any long-range transport in the area. Therefore, the EPA believes any emphasis on the sources of concern should prioritize localized sources, including point, area, and line sources of concern impacting the at-risk community of interest. Therefore, based upon the comments, the EPA is finalizing a broader example list of sources of concern to include localized sources such as point sources and transportation facilities, since these are the most commonly expected additional sources of concern. In response to the other sources of concern suggested by commenters, the EPA notes that while it has provided examples, the siting of monitors in EJ communities would not be limited to these examples. Thus, the revised set of examples would include “a major industrial area, point source(s), port, rail yard, airport, or other transportation facility or corridor.” In finalizing this modified list of examples, the EPA is not looking to prioritize one type of source category over another; rather, we intend to further illustrate the types of localized sources of pollution that might impact at-risk communities such that the siting of monitors nearby may be appropriate.

                    <P>
                        One commenter noted that the proposal may have unintentionally taken out the requirement related to specific design criteria for PM
                        <E T="52">2.5</E>
                         in 40 CFR part 58, appendix D, 4.7.1(b)(3) that, for an area with a requirement for an additional SLAMS monitor, it should “be sited in an area of poor air quality.” Thus, the language as proposed neither requires that such monitors be sited in areas of poor air quality, nor does it require that the monitor be sited in an area that is anticipated to experience poor air quality from unspecified (and thus potentially relatively insignificant) sources in the area. The EPA agrees that this was not our intention; the EPA wants to protect populations in at-risk communities by ensuring they are protected by the NAAQS when there are sources of concern that may be impacting them (
                        <E T="03">i.e.,</E>
                         not insignificant sources). Thus, the EPA is reinstating this requirement in the network design language and combining it with the examples of the types of localized sources of concern: “For areas with additional required SLAMS, a monitoring station is to be sited in an at-risk community with poor air quality, particularly where there are anticipated effects from sources in the area (
                        <E T="03">e.g.,</E>
                         a major industrial area, point source(s), port, rail yard, airport, or other transportation facility or corridor).”

                        To ensure minimally required monitoring sites appropriately represent exposures in at-risk communities, the EPA proposed that sites represent “area-wide” air quality near local sources of concern (88 FR 5674, January 27, 2023). Sites representing “area-wide” air quality are those monitors sited at neighborhood, urban, and regional scales, as well as those monitors sited at either micro- or middle-scale that are identified as being representative of many such locations in the same Metropolitan Statistical Area (MSA).

                         Most existing—as well as new or moved sites—are expected to be neighborhood-scale, which means that the monitoring stations would typically represent conditions throughout some reasonably homogeneous urban sub-region with dimensions of a few kilometers per part 58, appendix D, section 4.7.1(c)(3). Additionally, as described in § 58.30,

                    <P>The EPA received a few comments on its proposed requirement that minimally required sites represent “area-wide” air quality. One commenter stated that the inclusion of a provision for EJ would narrow the location of monitors to certain communities that may not best represent “areawide” air quality. Another commenter asked the EPA to consider removing requirements that sites be area-wide, since 24-hour and annual averaging times would miss short, elevated pollution events. A couple commenters had concerns with the difference in the scale of representation between EJ monitors using small scale and other NAAQS monitors using area-wide scale, in that area-wide scale would not protect those most at risk. However, another commenter agreed with the EPA that sites representing at-risk communities should represent area-wide air quality. In addition to these comments, the EPA received many comments with support for its proposed modifications to the network design criteria as whole.</P>

                        Regarding whether narrowing the location to certain communities may not best represent “area-wide” air quality, the EPA notes that sites are either identified as being area-wide or not; the EPA did not suggest it was seeking a best “area-wide” location. In response to the comment that area-wide site may miss short, elevated pollution events, the EPA is aware that there can be local, short-term spikes in PM

                         relatively unique micro-scale, or localized hot spot, or unique middle-scale impact sites), are not applicable to the annual NAAQS as described in § 58.30—Special consideration for data comparison to the NAAQS.

                    <P>After considering all the comments on this topic, the EPA is finalizing this part of the modification to the network design criteria to maintain, consistent with our long-standing network design criteria, that all minimally required sites are to represent area-wide air quality.</P>
                    <P>
                        In addition to using data from the robust network of almost 1,000 PM

                         sites for NAAQS and AQI purposes, having a stable network of long-term sites is especially valuable to examine trends and to inform long-term health and epidemiology studies that support reviews of the PM NAAQS. Therefore, while we proposed to add a PM
                        <E T="52">2.5</E>
                         network design criterion to address at-risk communities, many sites are likely already in valuable locations meeting one of the existing network design criteria (
                        <E T="03">i.e.,</E>
                         being in an area-wide area of expected maximum concentration or collocated with near-road sites) and supporting multiple monitoring objectives. Also, in many communities, there may already be sites meeting the network design criterion we proposed for at-risk communities. Thus, acknowledging the value of having long-term data from a consistent set of network sites, the EPA believes that moving sites should be minimized, especially in MSAs with a small number of sites. However, because a small number of new sites are expected to be required due to the existing minimum monitoring requirements (40 CFR part 58, appendix D, Table D-5)

                         NAAQS detailed in section II, and because sites occasionally have to be moved—due to, for example, loss of access to a site or a site no longer meeting siting criteria—the EPA believes it is appropriate to prioritize establishing sites in at-risk communities near sources of concern, whenever new sites are established, whether because it is a new site or a replacement for a prior site that must be moved. The EPA accordingly proposed that annual monitoring network plans (40 CFR 58.10(a)(1)) and 5-year assessments (40 CFR 58.10(d)) that include any of the few new sites that will be required include a commitment to examine the ability of existing and proposed sites to support air quality characterization for areas with at-risk populations in the community and the objective discussed herein.

                        In the proposal, the EPA identified that assessing and prioritizing at-risk communities for monitoring can be accomplished through several approaches (88 FR 5675). The most critical aspect of prioritizing which communities to monitor is their representation of the at-risk populations described earlier in this section. The other major consideration is whether the community is near a source or sources of concern. While many CBSAs have one or more sources of concern described above, some CBSAs will not have a quantity of emissions from sources of concern that result in an elevated level of measured PM
                        <E T="52">2.5</E>
                         concentrations in surrounding communities. The siting criteria to be “in the area of expected maximum concentration,” § 58.1 &amp; appendix D, section 4.7.1(b)(1) ensures there is a monitoring site in the community with the highest exposure in each CBSA with a monitoring requirement. Some CBSAs may also have a requirement to collocate a PM
                        <E T="52">2.5</E>
                         monitor at a near-road NO
                        <E T="52">2</E>
                         station. Therefore, the EPA believes that for cases where an additional PM
                        <E T="52">2.5</E>
                         site is required, we should include a criterion that the site be in an at-risk community when there are no sources of concern identified in that CBSA, or such sources do exist but are not expected to lead to elevated levels of measured PM
                        <E T="52">2.5</E>
                         concentrations.

                    <P>
                        In its proposal, the EPA highlighted that tools such as the EPA's EJSCREEN 
                        <SU>192</SU>
                        <FTREF/>

                         network design criteria (88 FR 5675-76, January 27, 2023). The EPA solicited comment on other tools and/or datasets that can be utilized to identify at-risk communities. In addition to support for using EJSCREEN, commenters identified several other options to identify at-risk communities intended for monitoring as part of the proposed revision to the PM
                        <E T="52">2.5</E>

                        For at-risk communities, monitoring agencies need data that can best inform where there may be elevated levels of exposures from sources of concern. While we use FRMs and FEMs to determine compliance with the NAAQS, data from these methods will only be available at existing sites. However, there are several additional datasets available that may be useful in evaluating the potential for elevated levels of exposure to communities near sources of concern. In the proposal, EPA identified potential non-regulatory monitoring datasets such as CSN, IMPROVE, and AQI non-regulatory PM
                        <E T="52">2.5</E>
                         continuous monitors; modeling data that utilizes emission inventory and meteorological data; emerging sensor networks such as those that comprise EPA and the USFS's Fire and Smoke Map;

                         and satellites that measure radiance and, with computational algorithms, can be used to estimate PM
                        <E T="52">2.5</E>
                         from aerosol optical depth (AOD) (88 FR 5675-76, January 27, 2023). The EPA solicited comment on datasets most useful to identify communities with high exposures for PM
                        <E T="52">2.5</E>

                         annual or 24-hour). In addition to providing information about datasets that can inform the NAAQS comparison, commenters additionally identified several types of datasets that may be useful to identify where there may be elevated levels of exposures from sources of concern. These datasets include satellite measurements, sensors, and sensor network data, which may all be useful to find hot spots in communities. Commenters also identified EJScreen and CalEnviroScreen, which are screening and mapping tools that utilize several datasets. Another commenter stated that to better understand exposure differences in disadvantaged communities, shorter measurement intervals should be measured and reported.

However, each of them may also have limitations and, therefore, users should be careful not to rely solely on one dataset versus another for all purposes. Fortunately, many of the available datasets are becoming easier to work with and more accessible, which will allow interested parties and monitoring agencies the opportunity to efficiently review the datasets and determine best applicability. For all of these reasons, the EPA is not finalizing a requirement to use a specific dataset or tool to identify at risk communities; however, whatever datasets a monitoring agency elects to use, its plan to use such data for purposes of meeting the network design requirements will be subject to EPA approval as part of the 40 CFR 58.10 annual monitoring network plan. Regarding the comment recommending shorter measurement intervals in measuring and reporting data to better understand exposure differences in disadvantaged communities, the EPA agrees and generally supports use of continuous methods. While we generally support use of continuous methods, approved filter-based technologies and methods also provide valuable air quality information. Therefore, the EPA is not requiring the use of automated continuous methods beyond what is already required in 40 CFR part 58, appendix D, section 4.7.2—Requirement for Continuous PM

                         sites in at-risk communities are FRMs and automated continuous FEMs (88 FR 5675-76, January 27, 2023). These are the methods eligible to compare to the PM

                         NAAQS, which is the primary objective for collecting this data. There are several other monitoring objectives that would benefit from the use of automated continuous FEMs. For example, having hourly data available from automated continuous FEMs would allow sites to provide data in near-real time to support forecasting and near real-time reporting of the AQI. Automated continuous methods are also useful to support evaluation of other methods such as low-cost sensors. When used in combination with on-site wind speed and wind direction measurements, automated FEMs can provide useful pollution roses, which help in identifying the origin of emissions that affect a community. Additionally, when collocated with continuous carbon methods such as an aethalometer, automated FEMs can help identify potential local carbon sources contributing to increased exposure in the community. While either FRMs or automated FEMs may be used at a site for comparison to the PM
                        <E T="52">2.5</E>
                         NAAQS, the EPA supports use of automated continuous FEMs at sites in at-risk communities.

                        The EPA requested comment on the measurement methods most useful to collocate with PM

                         in at-risk communities (88 FR 5675-76, January 27, 2023), and a few commenters provided input. One commenter recommended that the EPA should employ supplemental technologies and systems to increase coverage of the regulatory monitoring network and obtain more complete data to further protect public health and address environmental injustice in air pollution exposure. Another commenter recommended that the EPA invest in community-led monitoring and mobile air quality monitoring with a goal of recording block-level variabilities in data. And another commenter cited the value of community-deployed PM

                         NAAQS comparable sites in at-risk communities will allow for collaboration at multiple levels. The EPA strongly encourages such collaboration with impacted communities, and the measurement methods discussed here should be considered for use as appropriate.

                        In the proposal, the EPA identified that, to meet the revised network design criteria, there will be only a few new sites required,
                        <SU>198</SU>
                        <FTREF/>
                         plus any potentially moved sites in cases where an existing site lease is lost or otherwise requires relocation (88 FR 5675-76, January 27, 2023). To handle these new or relocated sites, the EPA proposed to build upon our existing regulatory process for selecting and approving these sites under 40 CFR 58.10 (88 FR 5676, January 27, 2023). In the proposal, we stated it would be appropriate to provide at least 12 months from the effective date of the final rule to allow monitoring agencies to initiate planning to implement these measures by seeking input from communities and other interested parties and considering whether to revise their PM
                        <E T="52">2.5</E>

                        or explain how their existing networks meet the objectives of the proposed modification to the network design criteria. Thus, the EPA proposed that monitoring agencies should address their approach to the question of whether any new or moved sites are needed and identify the potential communities in which the agencies are considering adding monitoring, if applicable, as well as identifying how they intend to meet the revised criteria for PM
                        <E T="52">2.5</E>
                         network design to address at-risk communities in the agencies' annual monitoring network plans due to each applicable EPA Regional office no later than July 1, 2024 (see 40 CFR 58.10). Specifics on the resulting new or moved sites for PM

                         network design to address at-risk communities were proposed to be detailed in the annual monitoring network plans due to each applicable EPA Regional office no later than July 1, 2025 (40 CFR 58.10). The EPA proposed that any new or moved sites would be required to be implemented and fully operational no later than 24 months from the date of approval of a plan or January 1, 2027, whichever comes first, but the EPA solicited comment on whether less time is needed (

                        The EPA received a few comments on its proposed timeline for monitoring agencies to identify, propose, and ultimately bring any new or moved sites online. One commenter asked that the timeline give states more time to start or move sites. A few commenters asked that the EPA only require meeting a timeline for identifying whether any new or moved sites are needed after the EPA has provided the monitoring agencies with guidance on the priority of the potential at-risk communities. One of those commenters further requests that the EPA allow at least 24 months from the date of approval of a § 58.10 monitoring plan identifying any relocation of monitoring sites or establishment of new monitoring sites to implement any changes to the network, citing the need for more time to work with local officials, procure monitoring equipment, and contract for services, all of which can cause significant delays in establishing a monitoring site. Another commenter asked that the EPA remain attentive to the challenges that States, and air agencies face regarding recruiting and retaining the specialized staff needed to support their existing regulatory monitoring networks and the capital resources needed to implement and sustain new monitoring stations in areas that are clearly meeting the existing PM NAAQS or any revised PM NAAQS. Another commenter stated that the July 1, 2024, timeline for a network evaluation this complex is insufficient, noting that they submit their draft annual monitoring network plan for public review and comment in mid-April for 30 days. Because the final plan is due July 1 and must include all comments and responses and describe any changes based on those comments, the timeline does not take these requirements into consideration by allowing for the more extensive assessment of changes that may be needed to meet the proposed new monitoring requirements. The commenter stated that it would be appropriate to provide at least 12 months from the effective date of this final rule for monitoring agencies to initiate planning to implement these measures, seek input, consider revisions to their PM
                        <E T="52">2.5</E>
                         networks, and explain how their existing networks meets the objectives of the final rule. The commenter notes that that SLT agencies should be provided a minimum of 18 months after the final recommendation is published to add this information to their § 58.10 annual monitoring network plans. Another commenter encourages the EPA to retain the proposed deadline for any newly required monitoring stations in at-risk communities to be operational (
                        <E T="03">i.e.,</E>
                         24 months after the July 2025 network plan approval or January 1, 2027, whichever is earlier). While the need for this data is urgent, the commenter stated that the process for procuring instrumentation, securing leases, and building permits, and other logistics in constructing new monitoring sites can take a significant amount of time, some of which are outside of agencies' control.

                    <P>
                        As stated earlier, the EPA received strong support for our proposal to modify the PM
                        <E T="52">2.5</E>
                         monitoring network design criteria to include an EJ factor that accounts for proximity of populations at increased risk of adverse health effects from PM
                        <E T="52">2.5</E>
                         exposures to sources of concern from a wide range of commenters. A few commenters support the timeline proposed, a few others support starting any new or moved sites sooner than proposed, while other commenters asked for more time or offered conditions regarding how to establish an appropriate timeline.
                    </P>
                    <P>
                        The EPA disagrees with the commenter that suggested the EPA should only require agencies to meet a timeline to identify whether any new or moved sites are needed after the EPA has provided the monitoring agencies with guidance on the priority of the potential at-risk communities, because the regulatory text provides all the guidance required for agencies to begin this process. As we explained above, the EPA does not anticipate that many new or moved sites will be required based on the final rule because we think most sites are already in suitable locations and long-term sites are highly valued. Also, monitoring agencies have discretion to provide to the EPA their recommendations regarding how they intend to meet the modifications to the PM
                        <E T="52">2.5</E>
                         monitoring network design criteria to include an EJ factor that accounts for proximity of populations at increased risk of adverse health effects from PM
                        <E T="52">2.5</E>
                         exposures to sources of concern. Overall, the EPA believes that having sites in the areas of expected maximum concentrations will best ensure that all communities are protected. Since there may be multiple choices for sites in EJ areas near sources of concern, the EPA acknowledges that there may be many locations that can meet the revised PM
                        <E T="52">2.5</E>
                         network design criteria. While, as we explained earlier, we want such sites to also be in areas of poor air quality, the sites in the area of maximum concentration will ensure that all communities are protected, there can be more flexibility afforded in the selection amongst at-risk communities to meet the revised requirements, since any alternative at-risk communities would already be protected.  
                    </P>
                    <P>
                        The EPA considered both the concerns and support for the timeline proposed and clarifies that the component of the proposed requirement regarding the need to identify potential new sites or an intention to move sites to be included in the annual monitoring network plan due to EPA on July 1, 2024, would be satisfied with a statement of intent to pursue a new site per the revised network design criteria and in consideration of the minimum monitoring requirements. While monitoring agencies may provide as much detail as they deem appropriate regarding the revised PM
                        <E T="52">2.5</E>
                         network design criteria in their annual monitoring network plans due on July 1, 2024, there is no expectation that any details on site-specific information would be included at that stage. We encourage agencies to provide their initial thinking on the communities they are most interested in monitoring pursuant to the revised network design criteria. Therefore, the EPA is finalizing the timeline as proposed, including the provision that monitoring agencies report their intention to add or move sites, where required, in their annual monitoring network plans due to each applicable EPA Regional office no later than July 1, 2024 (40 CFR 58.10). The 
                        <PRTPAGE P="16362"/>
                        monitoring agencies will then provide specifics on any new or moved sites for PM
                        <E T="52">2.5</E>
                         network design to address at-risk communities in the annual monitoring network plans due to each applicable EPA Regional office no later than July 1, 2025 (40 CFR 58.10). And any new or moved sites shall be implemented and fully operational no later than 24 months from the date of approval of a § 58.10 plan, or January 1, 2027, whichever comes first.

                        In summary, the EPA is finalizing modifications to the PM
                        <E T="52">2.5</E>
                         network design criteria to include an EJ factor to address at-risk communities with a focus on exposures from sources of concern in areas of poor air quality. While this modification to the PM
                        <E T="52">2.5</E>
                         network design requires sites to be located in at-risk communities, particularly those whose air quality is potentially affected by local sources of concern, such sites must still meet the requirement for being considered “area-wide” air quality. In finalizing this modification to the PM
                        <E T="52">2.5</E>
                         network design requirement, the EPA is making two changes in the final rule response to the comments received. First, the EPA is broadening our examples of “sources of concern” to include localized sources such as point sources and major transportation facilities or corridors. Second, the EPA is reinstating “poor air quality” in our requirement for the modified network design criteria, meaning the revised PM
                        <E T="52">2.5</E>
                         network design requirement now states: “For areas with additional required SLAMS, a monitoring station is to be sited in an at-risk community with poor air quality, particularly where there are anticipated effects from sources in the area (
                        <E T="03">e.g.,</E>

                        The EPA proposed changes to monitoring requirements in the Appendix E—Probe and Monitoring Path Siting Criteria for Ambient Air Quality Monitoring (88 FR 5676-78, January 27, 2023). Since 2006, the EPA finalized multiple rule revisions to establish siting requirements for PM

                         monitoring sites (78 FR 3285, January 15, 2013). Through these previous revisions to the regulatory text, some requirements were inadvertently omitted, and, over time, the clarity of this appendix was reduced through those omissions that, in a few instances, led to unintended and conflicting regulatory requirements. The EPA proposed to reinstate portions of previous Probe and Monitoring Path Siting Criteria Requirements from previous rulemakings, where appropriate, to restore the original intent.
                    </P>
                    <P>The EPA only received a few comments on the proposed rulemaking pertaining to the proposed changes regarding probe and monitoring path siting criteria for ambient air quality monitoring, most of which were supportive of the proposed revisions. One commenter noted that the image for Figure E-1 in Appendix E to part 58 was distorted and of extremely poor quality, rendering the text in places almost unreadable (88 FR 5712, January 27, 2023). The EPA makes several references to Figure E-1, which provides detailed information needed for assessing a range of acceptable probe distances from roadways based on a monitor's spatial scale. The commenter also stated that a higher quality image is needed for the figure so that agencies can fully interpret the figure to the extent that EPA requires. The EPA agrees with the commenter that a higher quality image for Figure E-1 is important and needed. Based on this comment, the EPA is finalizing the revision to Figure E-1 to clearly communicate the requirements of appendix E.</P>
                    <P>The EPA is revising appendix E in its entirety as proposed (88 FR 5709-5717, January 27, 2023) for clarity and as described in detail below.</P>
                    <HD SOURCE="HD3">a. Separate Section for Open Path Monitoring Requirements</HD>
                    <P>The EPA proposed to relocate all open path monitor siting criteria requirements to a separate section in appendix E from those requirements for siting samplers and monitors that utilize probe inlets (88 FR 5676, January 27, 2023). Separate sections for these distinct monitoring method types allows the EPA to more clearly articulate minimum technical siting requirements for each.</P>
                    <P>The EPA received one supportive comment to adopt this change and received no adverse comments. Another commenter stated the regulatory text of the proposal improves the clarity of the appendix but encouraged the EPA to break the summary tables down further into more manageable components (perhaps by pollutant). The commenter stated that summary tables for the proposed appendix continue to be a “jumbled mess of regulatory requirements.” The EPA agrees that the summary tables E-3 and E-6 in the proposal could be improved further. Also, the EPA found that footnote 3 of Table E-6 in the proposed rule was incomplete and corrected this editorial error.</P>
                    <P>Therefore, the EPA is making editorial changes to both summary tables E-3 and E-6 and finalizing the remainder of the language as proposed with the open path monitor siting criteria requirements placed into a separate section of the appendix.</P>
                    <HD SOURCE="HD3">b. Distance Precision for Spacing Offsets</HD>
                    <P>The EPA proposed to require that when rounding is performed to assess compliance with these siting requirements, the distance measurements will be rounded such as to retain at least two significant figures (88 FR 5676, January 27, 2023). The EPA proposed to communicate this rounding requirement in the regulatory text using footnotes in the tables of this appendix.</P>
                    <P>The EPA received two supportive comments and no adverse comments regarding this proposed change. While supportive of the proposal, one of the two supporting comments suggested it would be clearer if EPA explicitly defined a decimal in the distance values and round to the nearest tenths place for these assessments. The EPA disagrees with this recommendation because in some cases it would be more restrictive and burdensome than the proposed requirement that was intended to provide both clarity and flexibility. Therefore, the EPA is finalizing the language as proposed.</P>
                    <HD SOURCE="HD3">c. Summary Table of Probe Siting Criteria</HD>
                    <P>The EPA proposed to provide additional specificity and flexibility to the summary table for probe siting criteria by changing the “&gt;” (greater than) symbols to “≥” (greater than or equal to) symbols in the summary table E-4 (88 FR 5676, January 27, 2023). Because one commenter pointed out to the EPA that in the prior version of the rule there was no table E-4, as a clerical matter, we have renumbered this summary table to table E-3 in the final rule. This proposed minor revision to the summary table more clearly expresses the EPA's intent that the distance offsets provided in the summary tables in appendix E are acceptable for NAAQS compliance monitoring.</P>
                    <P>
                        The EPA received one comment supporting the proposal. The EPA received no adverse comments. Because

Therefore, the EPA is updating the table numbering and otherwise finalizing the tables as proposed.

                    <P>The EPA proposed to clarify and provide flexibility regarding siting monitors near minor sources by changing a requirement to a goal (88 FR 5676-77, January 27, 2023). To accomplish this, the EPA proposed to replace the “must” in the regulation with a “should.” While the EPA proposed to change this requirement to a goal, the EPA reiterated in the proposal that it recommends that sites with minor sources be avoided whenever practicable and probe inlets should be spaced as far from minor sources as possible when alternative monitoring stations are not suitable.</P>
                    <P>The EPA received one comment supporting the proposed revision and received no adverse comments. Therefore, the EPA is finalizing the language as proposed.</P>
                    <HD SOURCE="HD3">e. Spacing From Obstructions and Trees</HD>
                    <P>The EPA proposed to clarify and redefine that the minimum arc required to be free of obstructions for a probe inlet or monitoring path is 270-degrees and that probe inlets must be no closer than 10-meters to the driplines of any trees (88 FR 5677, January 27, 2023). These changes were proposed because of inconsistencies introduced into the rule with the 2006 rulemaking. Both are discussed in more detail in the following sections.</P>
                    <P>The majority of comments received were supportive of these proposed siting amendments and clarifications. Two commenters were not supportive of this proposal. One adverse comment focused on the potential that site modifications would be required if the minimum arc required to be free of obstructions for a probe inlet is 270-degrees. The second adverse comment pertained to the proposal to clarify distance requirements from tree driplines. The commenter stated they would expect significant challenges in meeting the proposed 20-meter tree dripline distance. This comment is not a substantive negative comment because the 20-meter distance provided in the proposal is a goal and not a requirement. As such, monitoring organizations should not expect additional challenges in meeting the probe siting requirements. One supportive commenter on the 270-degree minimum arc proposal also requested that the EPA acknowledge that some cases exist where monitoring is desired or necessary to protect the public health, but siting criteria cannot be met.</P>
                    <P>Based on the only two negative comments received from monitoring agencies or organizations, one of which was not substantive, the EPA believes most sites already meet these proposed requirements related to the arc and distance from dripline. However, the EPA also acknowledges that there may be limited cases where this proposed revision may require site modifications, and some sites may not be able to be achieve the proposed siting requirements, even with modifications to the site. For cases where long-term trend sites or monitors that determine the design value for their area cannot reasonably meet these regulatory siting requirements, the EPA encourages monitoring organizations to work with their respective EPA Regional offices to determine if a waiver from this siting criteria would be appropriate under appendix E, section 10.</P>
                    <P>These siting requirements are discussed in more detail below in sections VII.B.5.f and VII.B.5.h.</P>
                    <HD SOURCE="HD3">f. Reinstating Minimum 270-Degree Arc and Clarified 180-Degree Arc</HD>
                    <P>The EPA proposed to correct identified inconsistencies in the 270-degree requirement for unrestricted airflow to the probe inlet by reinstating the requirement stated in appendix E, paragraph 4(b), and to clarify that the continuous 180-degree minimum arc of unrestricted airflow provision is reserved for monitors sited on the side of a building or wall to comply with network design criteria requirements specified in appendix D of part 58 (88 FR 5677, January 27, 2023).</P>
                    <P>The EPA received two comments regarding this proposal, with one being supportive and one being negative. The adverse comment focused on the potential that site modifications would be required if this revision was made. The commenter supporting the proposal also requested that the EPA acknowledge that some cases exist where monitoring is desired or necessary to protect the public health, but siting criteria cannot be met. The EPA agrees with both commenters and acknowledges that there does exist limited cases where this proposal would require site modifications and some sites may not be able to be achieve the proposed siting requirement even with modifications to the site. For these cases, and especially when long-term trend sites or monitors that determine the design value for their area cannot reasonably meet these regulatory siting requirements, the EPA encourages monitoring organizations to work with their respective EPA Regional Offices to determine if a waiver from this siting criteria is appropriate through the provisions found in Section 10 of this appendix.</P>
                    <P>Based on the EPA only receiving a single negative comment regard the 270-degree and 180-degree provisions the EPA thinks most sites already meet these proposed requirements. Additionally, as stated above, the EPA is also retaining waiver provisions from these siting requirements for the remaining cases that can be exercised when appropriate. Therefore, the EPA is finalizing the language as proposed.</P>

                    <P>
                        The EPA proposed to clarify the definitions of “obstructions” and “obstacles” in the regulatory text (88 FR 5677, January 27, 2023). Stating that, “[o]bstructions to the air flow of the probe inlet are those obstacles that are horizontally closer than twice the vertical distance the obstacle protrudes above the probe inlet and can be reasonably thought to scavenge reactive gases or to restrict the airflow for any pollutant,” the EPA proposed to reiterate that the EPA does not generally consider objects or obstacles such as flag poles or site towers used for NO

                    </P>

                    <HD SOURCE="HD3">h. 10-Meter Tree Dripline Requirement</HD>
                    <P>The EPA proposed to reconcile the conflicting requirements in 5(a) and the prior table E-4 footnote 3 by clarifying that the probe inlet must always be no closer than 10 meters to the tree dripline (88 FR 5677, January 27, 2023). The EPA also proposed to reinstate the goal “that monitor probe inlets should be at least 20-meters from the driplines of trees,” a goal that was inadvertently omitted during previous rule revisions. In addition, the EPA proposed to clarify that if a tree or group of trees is considered an “obstruction,” section 4(a) will apply.</P>
                    <P>
                        As described above, the majority of comments received were supportive of the EPA proposed amendments and clarification, with two commenters focused on the possibility that monitoring agencies may not be able to meet the revised siting requirements. Specific to the proposed dripline requirement, the EPA reiterates that the 
                        <PRTPAGE P="16364"/>
                        20-meter tree dripline offset is not a requirement, but rather a goal. Monitoring programs should as much as practicable attempt to meet this 20-meter tree dripline offset goal but are only required to be at least 10 meters removed from tree driplines. If these requirements cannot be met, the EPA encourages monitoring organizations to contact their respective EPA Regional offices to determine if a waiver from this siting criteria would be appropriate under appendix E, section 10.
                    </P>
                    <P>Another commenter recommended that the proposal should also include an elevation specification. For instance, if a monitor is on the roof of a shelter, a tree below that roof should not be considered an obstruction no matter the distance to the dripline. The EPA considers this scenario to occur in practice only rarely. The EPA agrees that when the overall tree height is less than the height of the probe inlet, the tree is not obstructing the airflow to the probe inlet. However, a tree in such proximity to the probe inlet in many cases is not likely to remain at a height lower than the probe inlet. The EPA considers a scenario such as this to be best addressed in the waiver provisions of this appendix due both to the rarity of this occurring as well as the need for the EPA to periodically reassess whether tree growth has adversely impacted the site conditions.</P>
                    <P>For these reasons, the EPA is finalizing the language as proposed.</P>
                    <HD SOURCE="HD3">i. Spacing Requirement for Microscale Monitoring</HD>
                    <P>The EPA proposed to require that microscale sites for any pollutant shall have no trees or shrubs blocking the line-of-sight fetch between the monitor's probe inlet and the source under investigation (88 FR 5677, January 27, 2023). This proposed revision would bring consistency between near-road monitoring stations and other microscale monitoring.</P>
                    <P>The EPA received one comment on this proposed requirement expressing concerns regarding its practicality and legality. The commenter stated agencies may at times want to site a monitor close to a source, but the closest location will have trees in the line of sight on private property. Additionally, in some cases, the trees may have been planted for the purpose of reducing off-property emissions from a source such as a Concentrated Animal Feeding Operation (CAFO). The commenter further stated that the proposal mandates that State agencies order the removal of trees from private property to collect valid data.</P>
                    <P>The EPA disagrees that the proposed requirement is impractical or unlawful. The proposed requirement would not require, mandate, or otherwise empower monitoring agencies to force the removal of trees on private property. The EPA agrees with the commenter that trees may at times be planted as part of control strategies to reduce offsite emissions and thus protect the public, but the EPA disagrees with the commenter that the trees must be removed to perform ambient air monitoring in these locations. Rather, if trees or shrubs block the line-of-sight fetch between the monitor's probe inlet and the source under investigation, it is the EPA's position that, for most cases, a microscale designation does not accurately reflect the monitoring scale for this location, and instead the EPA would recommend that the monitoring scale be designated to a more representative monitoring scale such as middle scale or neighborhood scale.</P>
                    <P>Moreover, for cases where long-term trend sites or monitors that determine the design value for an area cannot reasonably meet this regulatory siting requirement, the EPA encourages monitoring organizations to work with their respective EPA Regional offices to determine if a waiver from this siting criteria may be appropriate under appendix E, section 10.</P>

                    <HD SOURCE="HD3">j. Waiver Provisions</HD>
                    <P>The EPA proposed to maintain the appendix E, section 10 waiver provisions in the current regulation for siting criteria, but to modify section 10.3 to require that waivers from the probe-siting criteria must be reevaluated and renewed minimally every 5 years (88 FR 5677-78, January 27, 2023).</P>
                    <P>The EPA received one comment supporting the proposal and no adverse comments. Therefore, the EPA is finalizing the language as proposed.</P>

The EPA proposed to add polyvinylidene fluoride (PVDF), also known as Kynar®, polytetrafluoroethylene (PTFE), and perfluoroalkoxy (PFA) to the list of approved materials for efficiently transporting gaseous criteria pollutants, and the use of Nafion

                         This mapping product uses Application Program Interfaces (APIs) where data sets are automatically shared on prespecified computer servers. Given the success of the Fire and Smoke Map, the EPA indicated interest in exploring the use of next-generation technologies to develop additional approaches, products, and applications to help address important non-regulatory air quality data needs. Therefore, the EPA solicited comment on the most important data uses and data sets to consider in such future initiatives. Such approaches and/or products could utilize historical or near real-time data. The EPA sought this input and prioritization on use of next generation technologies to help improve the utility of data to better support air quality management to improve public health and the environment.

                    <P>The EPA received comments from about two dozen entities on its request for comments on how to incorporate data from next generation technologies. The entities that provided comment included federal agencies; representatives of industry and industry groups; public health, medical, and environmental organizations; State, local and related multi-state organizations involved in air program management; Tribes and Tribal organizations involved in air program management; and other State and local governments.</P>
                    <P>
                        While there were some differences across commenters, a majority of the commenters support use of next generation data for non-regulatory purposes, but not for regulatory decision making due to their inherent uncertainties and limitations. The EPA also received comments from some environmental organizations support using alternative data for regulatory decision making.
                        <PRTPAGE P="16365"/>
                    </P>
                    <P>Many commenters pointed out that they are already successfully using sensor data and networks in supplemental and informational applications and support further expansion of these capabilities. Across many commenters, there was support for using next generation data as “fit for purpose,” filling in gaps, finding hot spots, identifying and addressing EJ concerns, and evaluating and informing network siting. The EPA acknowledges the successful examples of sensor data and networks for non-regulatory purposes. A few commenters support expanding the use of sensor data to provide real-time AQI; the EPA is interested in this use of next generation data as well. A few commenters pointed the need for the EPA to work closely with them and their communities to understand and use next generation data, while others expressed a desire for help developing best practices around collecting and using next generation data, developing products with data analysis/visualization, and developing appropriate QA/QC for sensor data. The EPA acknowledges each of these requests and expects to continue to work closely with SLTs and other stakeholders to understand and develop information on the collection and use of next generation data.</P>
                    <P>A few commenters offered more detailed comments. Some recommended that the EPA repropose implementation provisions related to next generation technologies with greater clarity to provide for meaningful comment. For example, the use of low-cost sensor and satellite data could be used in drawing nonattainment area boundaries or identifying sources for emissions control, but doing so would be such a significant change from prior EPA policy that it warrants a more specific proposal, beyond the scope of this request for comment. In response to this comment, the EPA notes it did not propose or change the use of non-regulatory measurement data as part of this proposal, but instead opened an opportunity to comment about the use of next generation technologies.</P>
                    <P>Another commenter stated that while low-cost sensor data can be invaluable for some purposes, the potentially overwhelming amount of data produced by sensors may present additional challenges to communities without the resources or expertise to analyze it. Cost is another concern associated with some next generation technologies of which some communities may not be aware, as the initial cost of the sensor alone is not indicative of the total cost of operation, which can include costs of internet access and servers. The EPA appreciates the need to consider all the costs of implementing and maintaining sensor data.</P>
                    <P>Another commenter stated that having a dense sensor network collocated with FRMs and FEMs could help ensure timely maintenance of the regulatory measurements in the event there appears to be a divergence of data. The EPA appreciates the comment that emphasizes how sensors could be used to complement the FRM and FEM data with regard to ensuring timely maintenance.</P>
                    <P>Another commentor strongly opposes incorporating sensor data into any EPA systems unless robust quality assurance (QA) practices are widely established and managed by qualified personnel. The EPA agrees that QA is necessary, and notes that the “fit for purpose” aspect of using sensor data will inform the appropriate QA associated with the intended use of such data.</P>
                    <P>
                        In summary, the EPA invited comment on how we should consider incorporating data from next generation technologies into our air monitoring efforts. In seeking comment on this topic, the EPA did not propose to add, edit, or delete any regulatory language associated with the PM NAAQS. The EPA received comments from a variety of entities that largely support using next generation data for a variety of purposes that supplement, but cannot replace, the measurement data from monitoring methods required (
                        <E T="03">i.e.,</E>
                         FRMs and FEMs) for regulatory decision making. Across many commenters, there was support for using next generation technologies and data as “fit for purpose,” filling in gaps, finding hot spots, identifying, and addressing EJ concerns, and evaluating and informing network siting. Quality assurance of the data will be an important component in the use of next generation technology data. The EPA will consider these comments as it continues its work with the co-regulated community comprised of SLT agencies and other stakeholders to understand and use next generation data and joint efforts to manage the nation's ambient air.

Such period may be extended for up to one year in the event the Administrator has insufficient information to promulgate the designations.” With respect to the NAAQS setting process, courts have interpreted the term “promulgation” to be signature and widespread dissemination of a final rule.

If, however, the EPA disagrees with the State's recommendation, then the EPA may elect to make modifications to the recommended designations. By no later than 120 days prior to promulgating the final designations, the EPA is required to notify States of any intended modifications to the State designation recommendations for any areas or portions thereof, including the boundaries of areas, as the EPA may deem necessary. States then have an opportunity to comment on the EPA's intended modification and tentative designation decision. If a State elects not to provide designation recommendations for any area, then the EPA must itself promulgate the designation that it deems appropriate.</P>

                        While section 107(d) of the CAA specifically addresses the designations process for States, the EPA intends to follow the same process for Tribes to the extent practicable, pursuant to section 301(d) of the CAA regarding Tribal authority, and the Tribal Authority Rule (63 FR 7254, February 12, 1998). To provide clarity and consistency in doing so, the EPA issued a guidance memorandum to our Regional Offices on working with Tribes during the designations process.

                        Consistent with the process used in previous area designations efforts, the EPA will evaluate each area on a case-by-case basis considering the specific facts and circumstances unique to the area to support area boundary decisions for the revised standard. The EPA intends to issue a designations memorandum which will provide information regarding the designations process. In broad overview, the EPA has historically used area-specific analyses to support nonattainment area boundary recommendations and final boundary determinations by evaluating factors such as air quality data, emissions and emissions-related data (

The EPA will then base the final designations on the most recent three consecutive years of complete, certified air quality monitoring data available at the time of final designations.

                         such as prescribed fires on wildland, wildfires, or high wind dust storms). Accordingly, for purposes of initial area designations for a new or revised NAAQS, an air agency may submit to the EPA an exceptional events demonstration with supporting information and analyses for each monitoring site and day the air agency claims the EPA should exclude from design value calculations for designations purposes.

                         Further, the EPA will continue to work with air agencies as they identify exceptional events that may influence decisions related to the initial area designations process, and to prepare and submit exceptional events demonstrations if appropriate. Importantly, air quality monitoring data may be influenced by emissions from prescribed fires on wildland and wildfires. The EPA's Exceptional Events Rule provides for both of these types of events to be considered as exceptional events, provided the affected air agencies submit exceptional events demonstrations that meet the procedural and technical requirements of the EPA's Exceptional Events Rule. To that end, the EPA has issued guidance addressing development of exceptional events demonstrations for both wildfire and prescribed fires on wildland.

                         In light of the growing frequency and severity of wildfire events, and expected increases in the application of prescribed fire as a means to achieve long-term reductions in high severity wildfire risk and associated smoke impacts, the EPA seeks to ensure that the Agency's exceptional events process provides an efficient and clear pathway for excluding data that may be affected by such events in a manner that is consistent with the Clean Air Act and the public health objectives of the NAAQS. Accordingly, the EPA is continuing to explore opportunities to develop additional tools that could assist air agencies in preparing exceptional events demonstrations for wildfires and prescribed fires on wildland. In addition, EPA intends to continue engaging with the U.S. Department of Agriculture, U.S. Department of the Interior, air agencies, and other stakeholders on these issues.

                    <P>
                        As discussed in the NPRM, the CAA directs States to address basic SIP requirements to implement, maintain, and enforce the NAAQS. Under CAA sections 110(a)(1) and (2), states are required to have State implementation plans that provide the necessary air quality management infrastructure that provides for the implementation, maintenance, and enforcement of the NAAQS. After the EPA promulgates a new or revised NAAQS, States are required to make a new SIP submission to establish that they meet the necessary structural requirements for such new or revised NAAQS or make changes to do so. The EPA refers to this type of SIP submission as an “infrastructure SIP submission.” Under CAA section 110(a)(1), all States are required to make these infrastructure SIP submissions within three years after the effective date of a new or revised primary standard. While the CAA authorizes the EPA to set a shorter time for States to make these SIP submissions, the EPA is requiring submission of infrastructure SIPs within three years of the effective date of this revised primary annual PM
                        <E T="52">2.5</E>

                        The EPA has provided general guidance to States concerning its interpretation of these requirements of CAA section 110(a)(1) and (2) in the context of infrastructure SIP submissions for a new or revised NAAQS.

                    <P>
                        As a reminder, the EPA notes that States are not required to address nonattainment plan requirements for purposes of the revised primary annual PM
                        <E T="52">2.5</E>
                         NAAQS on the same schedule as infrastructure SIP requirements. The EPA interprets the CAA such that two elements identified in section 110(a)(2) are not subject to the 3-year submission deadline of section 110(a)(1) and thus States are not required to address them in the context of an infrastructure SIP submission. The elements pertain to part D, in title I of the CAA, which addresses additional SIP requirements for nonattainment areas. Therefore, for the reasons explained below, the following section 110(a)(2) elements are considered by the EPA to be outside the scope of infrastructure SIP actions: (1) The portion of section 110(a)(2)(C), programs for enforcement of control measures and for construction or modification of stationary sources that applies to permit programs applicable in designated nonattainment areas (known as “nonattainment new source review”) under part D; and (2) section 110(a)(2)(I), which requires a SIP submission pursuant to part D, in its entirety.
                    </P>
                    <P>
                        Accordingly, the EPA does not expect States to address the requirement for a new or revised NAAQS in the infrastructure SIP submissions to include regulations or emissions limits developed specifically for attaining the relevant standard in areas designated nonattainment for the revised primary annual PM
                        <E T="52">2.5</E>
                         NAAQS. States are required to submit infrastructure SIP submissions for the revised primary annual PM
                        <E T="52">2.5</E>
                         NAAQS before they will be required to submit nonattainment plan SIP submissions to demonstrate attainment with the same NAAQS. States are required to submit nonattainment plan SIP submissions to provide for attainment and maintenance of a revised primary annual PM
                        <E T="52">2.5</E>
                         NAAQS within 18 months from the effective date of nonattainment area designations as required under CAA section 189(a)(2)(B). The EPA reviews and acts upon these later SIP submissions through a separate process. For this reason, the EPA does not expect States to address new nonattainment area emissions controls per section 110(a)(2)(I) in their infrastructure SIP submissions.
                    </P>
                    <P>
                        One of the required infrastructure SIP elements is that each State SIP must contain adequate provisions to prohibit, consistent with the provisions of title I of the CAA, emissions from within the State that will significantly contribute to nonattainment in, or interfere with maintenance by, any other State of the primary or secondary NAAQS.

                        <PRTPAGE P="16368"/>
                        element is often referred to as the “good neighbor” or “interstate transport” provision.
                        <SU>210</SU>
                        <FTREF/>
                         The provision has two prongs: significant contribution to nonattainment (prong 1), and interference with maintenance (prong 2). The EPA and States must give independent significance to prong 1 and prong 2 when evaluating downwind air quality problems under CAA section 110(a)(2)(D)(i)(I).
                        <SU>211</SU>
                        <FTREF/>
                         Further, case law has established that the EPA and States must implement requirements to meet interstate transport obligations in alignment with the applicable statutory attainment schedule of the downwind areas impacted by upwind-state emissions.

                        <FTREF/>
                         Thus, the EPA anticipates that States will need to address interstate transport obligations associated with this revised PM NAAQS, in alignment with the provisions of subpart 4 of part D of the CAA, as discussed in more detail in section VIII.C below. Specifically, States must implement any measures required to address interstate transport obligations as expeditiously as practicable and no later than the next statutory attainment date, 
                        <E T="03">i.e.,</E>

                         CAA section 188(c). States may find it efficient to make SIP submissions to address the interstate transport provisions separately from other infrastructure SIP elements.

                        Each State has the authority and responsibility to review its air quality management program's existing SIP provisions in light of a new or revised NAAQS to determine if any revisions are necessary to implement the new or revised NAAQS. Most States have revised and updated their SIPs in recent years to address requirements associated with other revised NAAQS. For certain infrastructure elements, some States may believe they already have adequate State regulations adopted and approved into the SIP to address a particular requirement with respect to the revised primary annual PM

                         In the case of such a submission, the State does not have to include a copy of the relevant provision (

                         rule or statute) itself. Rather, this certification submission should provide citations to the SIP-approved State statutes, regulations, or non-regulatory measures, as appropriate, in or referenced by the already EPA-approved SIP that meet particular infrastructure SIP element requirements. The State's infrastructure SIP submission should also include an explanation as to how the State has determined that those existing provisions meet the relevant requirements.

                    <P>Like any other SIP submission, that State can make such an infrastructure SIP submission certifying that it has already met some or all of the applicable requirements only after it has provided reasonable notice and opportunity for public hearing. This “reasonable notice and opportunity for public hearing” requirement for infrastructure SIP submissions is to meet the requirements of CAA sections 110(a) and 110(l). Under the EPA's regulations at 40 CFR part 51, if a public hearing is held, an infrastructure SIP submission must include a certification by the State that the public hearing was held in accordance with the EPA's procedural requirements for public hearings.

                    <P>The CAA, at parts C and D of title I, contains preconstruction review and permitting programs applicable to new major stationary sources and major modifications of existing major sources. The preconstruction review of each new major stationary source and major modification applies on a pollutant-specific basis, and the requirements that apply for each pollutant depend on whether the area in which the source is situated is designated as attainment (or unclassifiable) or nonattainment for that pollutant. In areas designated attainment or unclassifiable for a pollutant, the Prevention of Significant Deterioration (PSD) requirements under part C apply to construction at major sources. In areas designated nonattainment for a pollutant, the Nonattainment New Source Review (NNSR) requirements under part D apply to construction at major sources. Collectively, those two sets of permit requirements are commonly referred to as the “major New Source Review” or “major NSR” programs.</P>

                        The statutory requirements for a PSD permit program set forth under part C of title I of the CAA (sections 160 through 169) are addressed by the EPA's PSD regulations found at 40 CFR 51.166 (minimum requirements for an approvable PSD SIP) and 40 CFR 52.21 (PSD permitting program for permits issued under the EPA's Federal permitting authority). These regulations already apply to PM
                        <E T="52">2.5</E>
                         in areas that are designated attainment or unclassifiable for PM
                        <E T="52">2.5</E>
                         whenever a proposed new major source or major modification triggers PSD requirements for PM

                    <P>
                        For PSD, a “major stationary source” is one with the potential to emit 250 tons per year (tpy) or more of any regulated NSR pollutant, unless the new or modified source is classified under a list of 28 source categories contained in the statutory definition of “major emitting facility” in section 169(1) of the CAA. For those 28 source categories, a “major stationary source” is one with the potential to emit 100 tpy or more of any regulated NSR pollutant. A “major modification” is a physical change or a change in the method of operation of an existing major stationary source that results, first, in a significant emissions increase of a regulated NSR pollutant and, second, in a significant net emissions increase of that pollutant. See 40 CFR 51.166(b)(2)(i), 40 CFR 52.21(b)(2)(i). The EPA PSD regulations define the term “regulated NSR pollutant” to include any pollutant for which a NAAQS has been promulgated and any pollutant identified by the EPA as a constituent or precursor to such pollutant. See 40 CFR 51.166(b)(49), 40 CFR 52.21(b)(50). These regulations identify SO
                        <E T="52">2</E>
                         and NO

                         Thus, for PM

                        . Among other things, for each regulated NSR pollutant emitted or increased in a significant amount, the PSD program requires a new major stationary source or a major modification to apply the “best available control technology” (BACT) to limit emissions and to conduct an air quality impact analysis to demonstrate that the proposed major stationary source or major modification will not cause or contribute to a violation of any NAAQS or PSD increment.

Such comments are addressed in the Response to Comments portion of this action. The EPA is making this revised primary annual PM

                        contribute to a violation of the NAAQS. Section 165(a)(3)(B) of the CAA states that a proposed source may not construct unless it demonstrates that it will not cause or contribute to a violation of any NAAQS. This statutory requirement is implemented through a provision contained in the PSD regulations at 40 CFR 51.166(k) and 52.21(k).

                         If a source cannot make this demonstration, or if its initial air quality impact analysis shows that the source's impact would cause or contribute to a violation, the reviewing authority may not issue a PSD permit to that source. However, a PSD permit applicant may be able to make this demonstration if it compensates for the adverse impact that would otherwise cause or contribute to a violation of the NAAQS. In contrast to the NSR requirements for nonattainment areas, the PSD regulations do not explicitly specify remedial actions that a prospective source must take to address such a situation, but the EPA has historically recognized that sources applying for PSD permits may utilize offsetting reductions in emissions as part of the required PSD demonstration under CAA section 165(a)(3)(B).

                        Part D of title I of the CAA includes preconstruction review and permitting requirements applicable to new major stationary sources and major modifications located in areas designated nonattainment for a pollutant for which the EPA has established a NAAQS (

The EPA's regulations for the NNSR program are contained in 40 CFR 51.165 and 52.24 and part 51, appendix S. Specifically, the EPA has developed minimum program requirements for a NNSR program that is approvable in a SIP, and those requirements, which include requirements for PM

This interim program enables NNSR permitting in nonattainment areas by States that lack a SIP-approved NNSR permitting program during the time between the date of the relevant designation and the date that the EPA approves into the SIP a NNSR program.

                        For NNSR, “major stationary source” is generally defined as a source with the potential to emit at least 100 tpy of the regulated NSR pollutant for which the area is designated nonattainment. In some cases, however, the CAA and the NNSR regulations define “major stationary source” for NNSR in terms of a lower rate dependent on the pollutant and degree of nonattainment in the area.

                        Transportation conformity is required under CAA section 176(c) to ensure that transportation plans, transportation improvement programs (TIPs) and federally supported highway and transit projects will not cause or contribute to any new air quality violation, increase the frequency or severity of any existing violation, or delay timely attainment or any required interim emissions reductions or other milestones. Transportation conformity applies to areas that are designated as nonattainment or nonattainment areas that have been redesignated to attainment with an approved CAA section 175A maintenance plan (

                        The conformity requirement under CAA section 176(c) ensures that federal activities implemented by federal agencies will not interfere with a State's ability to attain and maintain the NAAQS. Under CAA 176(c)(1), the requirement prohibits Federal agencies from approving, permitting, licensing, or funding activities that do not conform to the purpose of the applicable SIP for the control and prevention of air pollution.

                        With regard to issues regarding prescribed fires, which were addressed earlier in this action, here is some additional information regarding prescribed fires and General Conformity regulations. Under the General Conformity regulations at 40 CFR 93.153(c)(4), a conformity evaluation is not required to support a decision by a federal agency to conduct or carry out prescribed burning when the burn is consistent with the terms of a land management plan or other plan that includes the prescribed burn at issue, where the overall plan that includes the burn was previously evaluated under 40 CFR part 93 subpart B by the responsible federal agency, and the agency found the plan conforms under CAA paragraphs 176(c)(1)(A) and (1)(B). This assumes the burn at issue will be conducted by meeting any conditions specified as necessary for meeting conformity in the agency's decision to approve the plan. Alternatively, a presumption of conformity applies also under 40 CFR 93.153(i)(2) for prescribed fires conducted in accordance with a Smoke Management Program that meets the requirements of the EPA's 1998 Interim Air Quality Policy on Wildland and Prescribed Fires or an equivalent replacement EPA policy. The preamble to the Exceptional Events Rule explains that the EPA adapted language associated with the six basic components of a certifiable Smoke Management Program for exceptional events purposes from the 1998 Interim Air Quality Policy on Wildland and Prescribed Fires (

The Exceptional Events Rule at 40 CFR 50.14(a)(3)(ii)(A) also indicates that certain requirements within the Exceptional Events Rule can be satisfied if a prescribed fire is conducted under a certified Smoke Management Program or using appropriate basic smoke management practices such as those identified in Table 1 to 40 CFR 50.14 (

Accordingly, the EPA submitted this action to the Office of Management and Budget (OMB) for review. Documentation of any changes made in response to the Executive Order 12866 review is available in the docket. The EPA prepared an illustrative analysis of the potential costs and benefits associated with this action. This analysis, “Regulatory Impact Analysis for the Reconsideration of the National Ambient Air Quality Standards for Particulate Matter,” is available in the Regulatory Impact Analysis (RIA) docket (EPA-HQ-OAR-2019-0587) and briefly summarized below. However, the CAA and judicial decisions make clear that the economic and technical feasibility of attaining ambient standards are not to be considered in setting or revising NAAQS, although such factors may be considered in the development of State plans to implement the standards. Accordingly, although an RIA has been prepared, the results of the RIA have not been considered in issuing this final rule.</P>

                             Rows may not appear to add correctly due to rounding. We provide a snapshot of costs and benefits in 2032, using the best available information to approximate social costs and social benefits recognizing uncertainties and limitations in those estimates. The estimated costs and monetized human health benefits associated with applying national control strategies do not fully account for all the emissions reductions needed to reach the final and more stringent alternative standard levels for some standard levels analyzed.

                             We assume that there is a cessation lag between the change in PM exposures and the total realization of changes in mortality effects. Specifically, we assume that some of the incidences of premature mortality related to PM

                             exposures occur in a distributed fashion over the 20 years following exposure, which affects the valuation of mortality benefits at different discount rates. Similarly, we assume there is a cessation lag between the change in PM exposures and both the development and diagnosis of lung cancer. The benefits are associated with two point estimates from two different epidemiologic studies, and we present the benefits calculated at a real discount rate of 3 percent. The monetized benefits exclude additional health and welfare benefits that could not be quantified.

                    <P>
                        Executive Order 13045 directs federal agencies to include an evaluation of the health and safety effects of the planned regulation on children in federal health and safety standards and explain why the regulation is preferable to potentially effective and reasonably feasible alternatives. This action is subject to Executive Order 13045 because it is a significant regulatory action under section 3(f)(1) of Executive Order 12866, and the EPA believes that the environmental health or safety risk addressed by this action may have a disproportionate effect on children. Accordingly, we have evaluated the environmental health or safety effects of PM exposures on children. The protection offered by these standards may be especially important for children because childhood represents a lifestage associated with increased susceptibility to PM-related health effects. Because children have been identified as a susceptible population, we have carefully evaluated the environmental health effects of exposure to PM pollution among children. Children make up a substantial fraction of the U.S. population, and often have unique factors that contribute to their increased risk of experiencing a health effect due to exposures to ambient air pollutants because of their continuous growth and development. As described in the 2019 Integrated Science Assessment, children may be particularly at risk for health effects related to ambient air PM

More detailed information on the evaluation of the scientific evidence and policy considerations pertaining to children, including an explanation for why the Administrator judges the revised standards to be requisite to protect public health, including the health of children, with an adequate margin of safety, are contained in section II.A.2. “Overview of the Health Effects Evidence”, section II.A.2.b “Public Health Implications and At-Risk Populations” and II.B “Conclusions on the Primary PM

                        This action is not a “significant energy action” because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. The purpose of this action is to revise level of the primary annual PM

Such strategies will be developed by States on a case-by-case basis, and the EPA cannot predict whether the control options selected by States will include regulations on energy suppliers, distributors, or users. Thus, the EPA concludes that this action does not constitute a significant energy action as defined in Executive Order 13211.

                        To the extent feasible, the EPA employs a Performance-Based Measurement System (PBMS), which does not require the use of specific, prescribed analytic methods. The PBMS is defined as a set of processes wherein the data quality needs, mandates or limitations of a program or project are specified and serve as criteria for selecting appropriate methods to meet those needs in a cost-effective manner. 
                        <PRTPAGE P="16375"/>
                        It is intended to be more flexible and cost effective for the regulated community; it is also intended to encourage innovation in analytical technology and improved data quality. Though the FRM defines the particular specifications for ambient monitors, there is some variability with regard to how monitors measure PM, depending on the type and size of PM and environmental conditions. Therefore, it is not practically possible to fully define the FRM in performance terms to account for this variability. Nevertheless, our approach in the past has resulted in multiple brands of monitors being approved as FRM for PM, and we expect this to continue. Also, the FRMs described in 40 CFR part 50 and the equivalency criteria described in 40 CFR part 53, constitute a performance-based measurement system for PM, since methods that meet the field testing and performance criteria can be approved as FEMs. Since finalized in 2006 (71 FR 61236, October 17, 2006) the new field and performance criteria for approval of PM
                        <E T="52">2.5</E>
                         continuous FEMs has resulted in the approval of 13 approved FEMs. In summary, for measurement of PM
                        <E T="52">2.5</E>
                         and PM
                        <E T="52">10</E>
                        , the EPA relies on both FRMs and FEMs, with FEMs relying on a PBMS approach for their approval. The EPA is not precluding the use of any other method, whether it constitutes a voluntary consensus standard or not, as long as it meets the specified performance criteria.

                        Socioeconomic status (SES) is a composite measure that includes metrics such as income, occupation, or education, and can play a role in access to healthy environments as well as access to healthcare. SES may be a factor that contributes to differential risk from PM

                                 The PEP is an independent assessment used to estimate total measurement system bias. These evaluations will be performed under the national performance evaluation program (NPEP) as described in section 2.4 of this appendix or a comparable program. A prescribed number of Performance evaluation sampling events will be performed annually within each PQAO. For PQAOs with less than or equal to five monitoring sites, five valid performance evaluation audits must be collected and reported each year. For PQAOs with greater than five monitoring sites, eight valid performance evaluation audits must be collected and reported each year. A valid performance evaluation audit means that both the primary monitor and PEP audit concentrations are valid and equal to or greater than 2 µg/m3. Siting of the PEP monitor must be consistent with section 3.2.3.4(c) of this appendix. However, any horizontal distance greater than 4 meters and any vertical distance greater than one meter must be reported to the EPA regional PEP coordinator.

                         The PEP is an independent assessment used to estimate total measurement system bias. These evaluations will be performed under the NPEP as described in section 2.4 of this appendix or a comparable program. Performance evaluations will be performed annually within each PQAO. For PQAOs with less than or equal to five monitoring sites, five valid performance evaluation audits must be collected and reported each year. For PQAOs with greater than five monitoring sites, eight valid performance evaluation audits must be collected and reported each year. A valid performance evaluation audit means that both the primary monitor and PEP audit concentrations are valid and equal to or greater than 2 µg/m3. Siting of the PEP monitor must be consistent with section 3.2.3.4(c) of this appendix. However, any horizontal distance greater than 4 meters and any vertical distance greater than one meter must be reported to the EPA regional PEP coordinator. Additionally for every monitor designated as a primary monitor, a primary quality assurance organization must:

                        3.2.4.3 Additional information concerning the PEP is contained in Reference 10 of this appendix. The calculations for evaluating bias between the primary monitor and the performance evaluation monitor for PM

                            <P>2.2.2 A request to update a designated methods calibration may be initiated by the instrument manufacturer of record or the EPA Administrator.

                                 continuous FEM calibration must meet the general submittal requirements of section 2.7 of this appendix.
                            </P>
                            <P>2.2.4 Data included in the request should represent a subset of representative locations where the method is operational. For cases with a small number of collocated FRMs and continuous FEMs sites, an updated candidate calibration may be limited to the sites where both methods are in use.</P>
                            <P>2.2.5 Data included in a candidate method updated calibration may include a subset of sites where there is a large grouping of sites in one part of the country such that the updated calibration would be representative of the country as a whole.</P>
                            <P>2.2.6 Improvements should be national in scope and ideally implemented through a firmware change.</P>
                            <P>2.2.7 The goal of a change to a methods calibration is to increase the number of sites meeting measurements quality objectives of the method as identified in section 2.3.1.1 of appendix A to this part.</P>
                            <P>2.2.8 For meeting measurement quality objectives (MQOs), the primary objective is to meet the bias goal as this statistic will likely have the most influence on improving the resultant data collected.</P>
                            <P>2.2.9 Precision data are to be included, but so long as precision data are at least as good as existing network data or meet the MQO referenced in section 2.2.8 of this appendix, no further work is necessary with precision.</P>
                            <P>2.2.10 Data available to use may include routine primary and collocated data.</P>
                            <P>2.2.11 Audit data may be useful to confirm the performance of a candidate updated calibration but should not be used as the basis of the calibration to keep the independence of the audit data.</P>
                            <P>2.2.12 Data utilized as the basis of the updated calibration may be obtained by accessing EPA's AQS database or future analogous EPA database.</P>
                            <P>2.2.13 Years of data to use in a candidate method calibration should include two recent years where we are past the certification period for the previous year's data, which is May 1 of each year.</P>
                            <P>2.2.14 Data from additional years is to be used to test an updated calibration such that the calibration is independent of the test years of interest. Data from these additional years need to minimally demonstrate that a larger number of sites are expected to meet bias MQO especially at sites near the level of the NAAQS for the PM indicator of interest.</P>
                            <P>2.2.15 Outliers may be excluded using routine outlier tests.</P>
                            <P>
                                2.2.16 The range of data used in a calibration may include all data available or alternatively use data in the range from the lowest measured data available up to 125% of the 24-hour NAAQS for the PM indicator of interest.
                                <PRTPAGE P="16396"/>
                            </P>
                            <P>2.2.17 Other improvements to a PM continuous method may be included as part of a recommended update so long as appropriate testing is conducted with input from EPA's Office of Research and Development (ORD) Reference and Equivalent (R&amp;E) Methods Designation program.</P>
                            <P>2.2.18 EPA encourages early communication by instrument manufacturers considering an update to a PM method. Instrument companies should initiate such dialogue by contacting EPA's ORD R&amp;E Methods Designation program. The contact information for this can be found at 40 CFR 53.4.</P>
                            <P>2.2.19 Manufacturers interested in improving instrument's performance through an updated factory calibration must submit a written modification request to EPA with supporting rationale.

                            <P>(a) This appendix contains specific location criteria applicable to ambient air quality monitoring probes, inlets, and optical paths of SLAMS, NCore, PAMS, and other monitor types whose data are intended to be used to determine compliance with the NAAQS. These specific location criteria are relevant after the general location has been selected based on the monitoring objectives and spatial scale of representation discussed in appendix D to this part. Monitor probe material and sample residence time requirements are also included in this appendix. Adherence to these siting criteria is necessary to ensure the uniform collection of compatible and comparable air quality data.</P>
                            <P>(b) The probe and monitoring path siting criteria discussed in this appendix must be followed to the maximum extent possible. It is recognized that there may be situations where some deviation from the siting criteria may be necessary. In any such case, the reasons must be thoroughly documented in a written request for a waiver that describes whether the resulting monitoring data will be representative of the monitoring area and how and why the proposed or existing siting must deviate from the criteria. This documentation should help to avoid later questions about the validity of the resulting monitoring data. Conditions under which the EPA would consider an application for waiver from these siting criteria are discussed in section 4 of this appendix.</P>
                            <P>(c) The pollutant-specific probe and monitoring path siting criteria generally apply to all spatial scales except where noted otherwise. Specific siting criteria that are phrased with “shall” or “must” are defined as requirements and exceptions must be granted through the waiver provisions. However, siting criteria that are phrased with “should” are defined as goals to meet for consistency but are not requirements.</P>

                                (a) It is important to understand the monitoring objective for a particular site in order to interpret this requirement. Local minor sources of a primary pollutant, such as SO
                                <E T="52">2</E>
                                , lead, or particles, can cause high concentrations of that particular pollutant at a monitoring site. If the objective for that monitoring site is to investigate these local primary pollutant emissions, then the site will likely be properly located nearby. This type of monitoring site would, in all likelihood, be a microscale-type of monitoring site. If a monitoring site is to be used to determine air quality over a much larger area, such as a neighborhood or city, a monitoring agency should avoid placing a monitor probe inlet near local, minor sources, because a plume from a local minor source should not be allowed to inappropriately impact the air quality data collected at a site. Particulate matter sites should not be located in an unpaved area unless there is vegetative ground cover year-round, so that the impact of windblown dusts will be kept to a minimum.

                                 or NO. The separation distance should take into account the heights of the flues, type of waste or fuel burned, and the sulfur content of the fuel.

To avoid this interference, the probe inlet must have unrestricted airflow pursuant to paragraph (b) of this section and should be located at a distance from obstacles. The horizontal distance from the obstacle to the probe inlet must be at least twice the height that the obstacle protrudes above the probe inlet. An obstacle that does not meet the minimum distance requirement is considered an obstruction that restricts airflow to the probe inlet. The EPA does not generally consider objects or obstacles such as flag poles or site towers used for NOy convertors and meteorological sensors, etc. to be deemed obstructions.
                            </P>
                            <P>(b) A probe inlet located near or along a vertical wall is undesirable because air moving along the wall may be subject to removal mechanisms. A probe inlet must have unrestricted airflow with no obstructions (as defined in paragraph (a) of this section) in a continuous arc of at least 270 degrees. An unobstructed continuous arc of 180 degrees is allowable when the applicable network design criteria specified in appendix D of this part require monitoring in street canyons and the probe is located on the side of a building. This arc must include the predominant wind direction for the season of greatest pollutant concentration potential. For particle sampling, there must be a minimum of 2.0 meters of horizontal separation from walls, parapets, and structures for rooftop site placement.</P>
                            <P>(c) A sampling station with a probe inlet located closer to an obstacle than required by the criteria in this section should be classified as middle scale or microscale, rather than neighborhood or urban scale, since the measurements from such a station would more closely represent these smaller scales.</P>
                            <P>(d) For near-road monitoring stations, the monitor probe shall have an unobstructed air flow, where no obstacles exist at or above the height of the monitor probe, between the monitor probe and the outside nearest edge of the traffic lanes of the target road segment.</P>

To reduce this possible interference/obstruction, the probe inlet should be 20 meters or more from the drip line of trees and must be at least 10 meters from the drip line of trees. If a tree or group of trees is an obstacle, the probe inlet must meet the distance requirements of section 2.3 of this appendix.

For microscale traffic corridor sites, the location must be greater than or equal 5.0 meters and less than or equal to 15 meters from the major roadway. For the microscale street canyon site, the location must be greater than or equal 2.0 meters and less than or equal to 10 meters from the roadway. For the middle scale site, a range of acceptable distances from the roadway is shown in Figure E-1 of this appendix. This figure also includes separation distances between a roadway and neighborhood or larger scale sites by default. Any PM probe inlet at a site, 2.0 to 15 meters high, and further back than the middle scale requirements will generally be neighborhood, urban or regional scale. For example, according to Figure E-1 of this appendix, if a PM sampler is primarily influenced by roadway emissions and that sampler is set back 10 meters from a 30,000 ADT (average daily traffic) road, the site should be classified as microscale, if the sampler's inlet height is between 2.0 and 7.0 meters. If the sampler's inlet height is between 7.0 and 15 meters, the site should be classified as middle scale. If the sampler is 20 meters from the same road, it will be classified as middle scale; if 40 meters, neighborhood scale; and if 110 meters, an urban scale.</P>

Of the above materials, only borosilicate glass, PVDF, PTFE, PFA, and FEP have been found to be acceptable for use as intake sampling lines for all the reactive gaseous pollutants.

Therefore, borosilicate glass, PVDF, PTFE, PFA, FEP, or their equivalents must be the only material in the sampling train (from probe inlet to the back of the monitor) that can be in contact with the ambient air sample for reactive gas monitors.

                            <P>(b) For volatile organic compound (VOC) monitoring at PAMS, FEP Teflon® is unacceptable as the probe material because of VOC adsorption and desorption reactions on the FEP Teflon®. Borosilicate glass, stainless steel, or their equivalents are the acceptable probe materials for VOC and carbonyl sampling. Care must be taken to ensure that the sample residence time is kept to 20 seconds or less.</P>

                                (c) No matter how nonreactive the sampling probe material is initially, after a period of use, reactive particulate matter is deposited on the probe walls. Therefore, the time it takes the gas to transfer from the probe inlet to the sampling device is critical. Ozone in the presence of nitrogen oxide (NO) will show significant losses, even in the most inert probe material, when the residence time exceeds 20 seconds.

                            <P>Table E-3 of this appendix presents a summary of the general requirements for probe siting criteria with respect to distances and heights. Table E-3 requires different elevation distances above the ground for the various pollutants. The discussion in this appendix for each of the pollutants describes reasons for elevating the monitor or probe inlet. The differences in the specified range of heights are based on the vertical concentration gradients. For source oriented and near-road monitors, the gradients in the vertical direction are very large for the microscale, so a small range of heights are used. The upper limit of 15 meters is specified for the consistency between pollutants and to allow the use of a single manifold for monitoring more than one pollutant.</P>

                                (a) It is important to understand the monitoring objective for a particular site in order to interpret this requirement. Local minor sources of a primary pollutant, such as SO

                                 can cause high concentrations of that particular pollutant at a monitoring site. If the objective for that monitoring site is to investigate these local primary pollutant emissions, then the site will likely be properly located nearby. This type of monitoring site would, in all likelihood, be a microscale type of monitoring site. If a monitoring site is to be used to determine air quality over a much larger area, such as a neighborhood or city, a monitoring agency should avoid placing a monitoring path near local, minor sources, because a plume from a local minor source should not be allowed to inappropriately impact the air quality data collected at a site.

                                 or NO. The separation distance should take into account the heights of the flues, type of waste or fuel burned, and the sulfur content of the fuel.

To avoid this interference, at least 90 percent of the monitoring path must have unrestricted airflow and should be located at a distance from obstacles. The horizontal distance from the obstacle to the monitoring path must be at least twice the height that the obstacle protrudes above the monitoring path. An obstacle that does not meet the minimum distance requirement is considered an obstruction that restricts airflow to the monitoring path. The EPA does not generally consider objects or obstacles such as flag poles or site towers used for NOy convertors and meteorological sensors, etc. to be deemed obstructions.

                            <P>(b) A monitoring path located near or along a vertical wall is undesirable because air moving along the wall may be subject to removal mechanisms. At least 90 percent of the monitoring path for open path analyzers must have unrestricted airflow with no obstructions (as defined in paragraph (a) of this section) in a continuous arc of at least 270 degrees. An unobstructed continuous arc of 180 degrees is allowable when the applicable network design criteria specified in appendix D of this part require monitoring in street canyons and the monitoring path is located on the side of a building. This arc must include the predominant wind direction for the season of greatest pollutant concentration potential.</P>

                                (c) Special consideration must be given to the use of open path analyzers given their inherent potential sensitivity to certain types of interferences and optical obstructions. A monitoring path must be clear of all trees, brush, buildings, plumes, dust, or other optical obstructions, including potential obstructions that may move due to wind, human activity, growth of vegetation, etc. Temporary optical obstructions, such as rain, particles, fog, or snow, should be considered when siting an open path analyzer. Any of these temporary obstructions that are of sufficient density to obscure the light beam will negatively affect the ability of the open path analyzer to continuously measure pollutant concentrations. Transient, but significant obscuration of especially longer measurement paths, could occur as a result of certain meteorological conditions (
                                <E T="03">e.g.,</E>
                                 heavy fog, rain, snow) and/or aerosol levels that are of a sufficient density to prevent the open path analyzer's light transmission. If certain compensating measures are not otherwise implemented at the onset of monitoring (

                                 shorter path lengths, higher light source intensity), data recovery during periods of greatest primary pollutant potential could be compromised. For instance, if heavy fog or high particulate levels are coincident with periods of projected NAAQS-threatening pollutant potential, the representativeness of the resulting data record in reflecting maximum pollution concentrations may be substantially impaired despite the fact that the site may otherwise exhibit an acceptable, even exceedingly high, overall valid data capture rate.

                            <P>(d) A sampling station with a monitoring path located closer to an obstacle than required by the criteria in this section should be classified as middle scale or microscale, rather than neighborhood or urban scale, since the measurements from such a station would more closely represent these smaller scales.  </P>
                            <P>(e) For near-road monitoring stations, the monitoring path shall have an unobstructed air flow, where no obstacles exist at or above the height of the monitoring path, between the monitoring path and the outside nearest edge of the traffic lanes of the target road segment.</P>

Table E-4 of this appendix provides the required minimum separation distances between a roadway and at least 90 percent of a monitoring path for various ranges of daily roadway traffic. A monitoring site with a monitoring path located closer to a roadway than allowed by the Table E-4 requirements should be classified as microscale or middle scale, rather than neighborhood or urban scale, since the measurements from such a site would more closely represent these smaller scales. The monitoring path(s) must not cross over a roadway with an average daily traffic count of 10,000 vehicles per day or more. For locations where a monitoring path crosses a roadway with fewer than 10,000 vehicles per day, monitoring agencies must consider the entire segment of the monitoring path in the area of potential atmospheric interference from automobile emissions. Therefore, this

                                calculation must include the length of the monitoring path over the roadway plus any segments of the monitoring path that lie in the area between the roadway and minimum separation distance, as determined from Table E-4 of this appendix. The sum of these distances must not be greater than 10 percent of the total monitoring path length.

Table E-5 of this appendix provides the required minimum separation distances between a roadway and at least 90 percent of a monitoring path for various ranges of daily roadway traffic. A site with a monitoring path located closer to a roadway than allowed by the Table E-4 requirements should be classified as microscale or middle scale rather than neighborhood or urban scale. The monitoring path(s) must not cross over a roadway with an average daily traffic count of 10,000 vehicles per day or more. For locations where a monitoring path crosses a roadway with fewer than 10,000 vehicles per day, monitoring agencies must consider the entire segment of the monitoring path in the area of potential atmospheric interference form automobile emissions. Therefore, this calculation must include the length of the monitoring path over the roadway plus any segments of the monitoring path that lie in the area between the roadway and minimum separation distance, as determined from Table E-5 of this appendix. The sum of these distances must not be greater than 10 percent of the total monitoring path length.

                            <P>The cumulative length or portion of a monitoring path that is affected by minor sources, trees, or roadways must not exceed 10 percent of the total monitoring path length.</P>

                            <P>The monitoring path length must not exceed 1.0 kilometer for open path analyzers in neighborhood, urban, or regional scale. For middle scale monitoring sites, the monitoring path length must not exceed 300 meters. In areas subject to frequent periods of dust, fog, rain, or snow, consideration should be given to a shortened monitoring path length to minimize loss of monitoring data due to these temporary optical obstructions. For certain ambient air monitoring scenarios using open path analyzers, shorter path lengths may be needed in order to ensure that the monitoring site meets the objectives and spatial scales defined in appendix D to this part. The Regional Administrator may require shorter path lengths, as needed on an individual basis, to ensure that the SLAMS sites meet the appendix D requirements. Likewise, the Administrator may specify the maximum path length used at NCore monitoring sites.</P>

                            <P>Table E-6 of this appendix presents a summary of the general requirements for monitoring path siting criteria with respect to distances and heights. Table E-6 requires different elevation distances above the ground for the various pollutants. The discussion in this appendix for each of the pollutants describes reasons for elevating the monitoring path. The differences in the specified range of heights are based on the vertical concentration gradients. For source oriented and near-road monitors, the gradients in the vertical direction are very large for the microscale, so a small range of heights are used. The upper limit of 15 meters is specified for the consistency between pollutants and to allow the use of a monitoring path for monitoring more than one pollutant.</P>

                                     When the monitoring path is located on a rooftop, this separation distance is in reference to walls, parapets, or penthouses located on roof.

                                     At least 90 percent of the monitoring path should be greater than 20 meters from the dripline of tree(s) and must be 10-meters from the dripline.

                                     The monitoring path should be away from minor sources, such as furnace or incineration flues. The separation distance is dependent on the height of the minor source's emission point (such as a flue), the type of fuel or waste burned, and the quality of the fuel (sulfur, ash, or lead content). This criterion is designed to avoid undue influences from minor sources.

                            <P>Most sampling probes or monitors can be located so that they meet the requirements of this appendix. New sites, with rare exceptions, can be located within the limits of this appendix. However, some existing sites may not meet these requirements and may still produce useful data for some purposes. The EPA will consider a written request from the State, or where applicable local, agency to waive one or more siting criteria for some monitoring sites providing that the State or their designee can adequately demonstrate the need (purpose) for monitoring or establishing a monitoring site at that location.</P>
                            <P>4.1 For a proposed new site, a waiver may be granted only if both the following criteria are met:</P>
                            <P>4.1.1 The proposed new site can be demonstrated to be as representative of the monitoring area as it would be if the siting criteria were being met.</P>
                            <P>
                                4.1.2 The monitor or probe cannot reasonably be located so as to meet the siting criteria because of physical constraints (
                                <E T="03">e.g.,</E>
                                 inability to locate the required type of site the necessary distance from roadways or obstructions).
                            </P>
                            <P>4.2 For an existing site, a waiver may be granted if either the criterion in section 4.1.1 or the criterion in 4.1.2 of this appendix is met.</P>
                            <P>4.3 Cost benefits, historical trends, and other factors may be used to add support to the criteria in sections 4.1.1 and 4.1.2 of this appendix; however, by themselves, they will not be acceptable reasons for the EPA to grant a waiver. Written requests for waivers must be submitted to the Regional Administrator. Granted waivers must be renewed minimally every 5 years and ideally as part of the network assessment as defined in § 58.10(d). The approval date of the waiver must be documented in the annual monitoring network plan to support the requirements of § 58.10(a)(1) and 58.10(b)(10).</P>

                                 For each pollutant, the AQI transforms ambient concentrations to a scale from 0 to 500. As appropriate, the AQI is associated with the NAAQS for each pollutant. In most cases, the index value of 100 is associated with the numerical level of the short-term standard (
                                <E T="03">i.e.,</E>
                                 averaging time of 24-hours or less) for each pollutant. The index value of 50 is associated with the numerical level of the annual standard for a pollutant, if there is one, at one-half the level of the short-term standard for the pollutant or at the level at which it is appropriate to begin to provide guidance on cautionary language. Higher categories of the index are based on the potential for increasingly serious health effects to occur following exposure and increasing proportions of the population that are likely to be affected. The reported AQI corresponds to the pollutant with the highest calculated AQI. For the purposes of reporting the AQI, the sub-indexes for PM
                                <E T="52">10</E>

                                 are to be considered separately. The pollutant responsible for the highest index value (the reported AQI) is called the “main” pollutant for that day.

                                     Areas are generally required to report the AQI based on 8-hour ozone values. However, there are a small number of areas where an AQI based on 1-hour ozone values would be more precautionary. In these cases, in addition to calculating the 8-hour ozone index value, the 1-hour ozone index value may be calculated, and the maximum of the two values reported.

                        ”) decision issued on April 21, 2020, the D.C.

                         Emissions data collected from the exhaust stacks of existing taconite indurating furnaces indicate that Hg is emitted from the source category. However, Hg emissions from the Taconite Iron Ore Processing source category are not regulated under the existing Taconite Iron Ore Processing NESHAP. To meet the EPA's obligations under CAA section 112(d)(6), in this action, the EPA is establishing new standards for Hg emissions from the Taconite Iron Ore Processing source category that reflect MACT for Hg emitted from taconite indurating furnaces, pursuant to CAA sections 112(d)(2) and (3).

                    <HD SOURCE="HD2">B. What is the source category and how does the current NESHAP regulate its HAP emissions?</HD>
                    <P>The Taconite Iron Ore Processing NESHAP (codified at 40 Code of Federal Regulations (CFR) part 63, subpart RRRRR) applies to each new or existing ore crushing and handling operation, ore dryer, pellet indurating furnace, and finished pellet handling operation at a taconite iron ore processing plant that is (or is part of) a major source of HAP emissions. Taconite iron ore processing plants separate and concentrate iron ore from taconite, a low-grade iron ore containing 20- to 25-percent iron, and produce taconite pellets, which are 60- to 65-percent iron. The current NESHAP includes particulate matter (PM) limits that, prior to this final action, served as a surrogate for particulate metal HAP, HCl, and HF emissions. The existing PM emissions limits were summarized in table 2 of the proposal (see 88 FR 30917; May 15, 2023). The current NESHAP does not presently include standards for Hg emissions.</P>
                    <P>
                        There are currently eight taconite iron ore processing plants in the United States: six plants are located in Minnesota and two are located in Michigan. This includes the Empire Mining facility in Michigan, which maintains an air quality permit to operate, but has been indefinitely idled since 2016 and is therefore not included

                    <HD SOURCE="HD2">C. What changes did we propose for the Taconite Iron Ore Processing source category?</HD>
                    <P>
                        On May 15, 2023, the EPA published a proposal in the 
                        <E T="04">Federal Register</E>
                         to set MACT standards for Hg emissions from indurating furnaces in the source category and to revise the existing emission standards for HCl and HF for indurating furnaces. The PM emission limits in the current NESHAP will continue to serve as surrogate for particulate metal HAP (
                        <E T="03">e.g.,</E>
                         nickel and arsenic). The EPA proposed that compliance with the emission standards for Hg, HCl, and HF be demonstrated through operating limits, monitoring, and performance testing. We also proposed minor changes to the electronic reporting requirements found in 40 CFR 63.9641(c) and 40 CFR 63.9641(f)(3) to reflect new procedures for reporting CBI that included an email address for owners and operators to electronically submit compliance reports containing CBI to the Office of Air Quality Planning and Standards (OAQPS) CBI Office. Finally, we requested comment on our evaluation that the addition of 1-bromopropane (1-BP) to the CAA section 112 HAP list would not impact the Taconite Iron Ore Processing NESHAP because, based on our knowledge of the source category and available emissions data, 1-BP is not emitted from this source category.

                    <P>
                        As described in the May 15, 2023, proposal (88 FR 30917), we proposed MACT standards for Hg for new and existing indurating furnaces that reflected the MACT floor level of control, based on the 99-percent upper prediction limit (UPL), of 1.4 × 10
                        <E T="51">−5</E>
                         pounds of Hg emitted per long ton of taconite pellets produced (lb/LT) for existing sources and 3.1 × 10
                        <E T="51">−6</E>
                         lb/LT for new sources. We also proposed an emissions averaging compliance alternative that would allow taconite iron ore processing facilities with more than one existing indurating furnace to comply with a Hg emissions limit of 1.26 × 10
                        <E T="51">−5</E>
                         lb/LT by averaging emissions on a production-weighted basis for two or more existing indurating furnaces located at the same facility. In the proposal, we explained that the emissions averaging compliance alternative reflected a 10 percent adjustment factor to the proposed MACT floor standard and that we expected this 10 percent adjustment factor would result in Hg reductions greater than those achieved by compliance with the MACT floor on a unit-by-unit basis. We proposed that compliance with the Hg MACT standards would be demonstrated through initial and periodic performance testing (completed at least twice per 5-year permit term), establishing operating limits for each control device used to comply with the Hg standards, and installing and operating continuous parameter monitoring systems (CPMS) to ensure continuous compliance with the Hg standards.  
                    </P>
                    <P>For the proposal, in addition to calculating the MACT floor, pursuant to CAA section 112(d)(2), we also assessed more stringent “beyond-the-floor” (BTF) regulatory options for the Hg MACT standards. As discussed in the proposal (88 FR 30923), unlike the MACT floor's minimum stringency requirements, the EPA must examine various impacts of the more stringent BTF regulatory options in determining whether MACT standards are to reflect BTF requirements. These impacts include the cost of achieving additional emissions reductions beyond those achieved by the MACT floor level of control, any non-air quality health and environmental impacts that would result from imposing controls BTF, and energy requirements of such BTF measures. If the EPA concludes that the more stringent regulatory options have unreasonable impacts, the EPA selects the MACT floor level of control as MACT. However, if the EPA concludes that impacts associated with BTF levels of control are reasonable in light of additional HAP emissions reductions achieved, then the EPA selects those BTF levels as MACT.</P>
                    <P>
                        We considered BTF regulatory options that were 10, 20, 30, and 40 percent more stringent than the MACT floor and calculated the capital and annual costs as well as secondary impacts associated with each option. For a detailed discussion of our analysis of emissions reductions and potential secondary impacts developed for the proposal, please see the memorandum, 
                        <E T="03">Development of Impacts for the Proposed Amendments to the NESHAP for Taconite Iron Ore Processing,</E>
                         which is available in the docket for this action. We proposed that requiring new or existing furnaces to meet BTF emission limits was not reasonable based on the estimated capital and operating costs and cost-effectiveness.

                         Industry commenters provided data that they indicated corrected the Hg stack test data submitted in response to the CAA section 114 Information Collection Request (ICR) sent to the taconite facilities in 2022 for the Tilden, UTAC, Keetac, and Hibbing facilities that were used when calculating the baseline emissions, the MACT floor standards, and the emission reductions. The commenters indicated that the error in the Keetac emissions data resulted in an overestimate of both the baseline emissions and the estimated emission reductions that could be achieved if the proposed Hg standards were adopted.

                         In response to these comments and revised data provided, the EPA reviewed the Hg emissions data that we used in the proposal to calculate baseline Hg emissions. At proposal we estimated total baseline Hg emissions were 1,010 pounds per year. The EPA confirmed that errors were present in the Hg emissions data used to calculate the baseline emissions. We revised the emissions data as appropriate based on the emissions data provided by industry commenters and recalculated the baseline emissions, MACT floor emission limits, emission reductions, and estimated capital and annual costs accordingly for the final rule. The updates to the emissions data did not impact the MACT floor limit for existing sources but did decrease the baseline emissions and the expected Hg emissions reductions for existing sources. The updates to the emissions data changed the Hg standard for new sources from 3.1 × 10
                        <E T="51">−6</E>
                         lb/LT to 2.6 × 10
                        <E T="51">−6</E>
                         lb/LT. The updated baseline Hg emissions for the final rule are estimated to be 751 pounds per year (0.38 tons per year (tpy)). We estimate 
                        <PRTPAGE P="16411"/>
                        that unit-by-unit compliance with the final MACT floor limit will result in a reduction of 232 pounds of Hg emissions per year and a reduction of 247 pounds per year of Hg emissions if all facilities with more than one existing taconite furnace elect to demonstrate compliance through the emissions averaging compliance alternative.

                         One commenter recommended the proposed limit for the emissions averaging compliance alternative for existing sources should have the same number of significant figures as the MACT floor limit. Instead of 1.26 × 10
                        <E T="51">−5</E>
                         lb/LT, the limit for the emissions averaging compliance alternative for existing sources would be rounded up to 1.3 × 10

                         The EPA agrees with the commenter that the Hg emission limit for the emissions averaging compliance option should have only two significant figures. The limit cannot have more significant figures than Hg MACT floor from which it was derived, which has only two significant figures. As recommended by commenters, the Hg emission limit in the final rule is revised to 1.3 × 10
                        <E T="51">−5</E>
                         lb/LT so that the limit for the emissions averaging compliance alternative has the same number of significant figures as the other Hg limits finalized in this rulemaking.

                        We estimate that the final Hg emissions averaging compliance alternative will reduce Hg emissions by 247 pounds per year, if Hibbing and Minntac elect to demonstrate compliance through the emissions averaging compliance alternative by each facility installing mercury controls on two furnaces and averaging the emissions across all furnaces located at their facility. We expect that, should Hibbing and Minntac elect to demonstrate compliance through the emissions averaging compliance alternative, the Hg reductions would still be greater than the reductions we anticipate would be achieved through unit-by-unit compliance with the MACT floor level of control. For additional details, please refer to section IV.A.1 of the proposal preamble (88 FR 30925).

                         Commenters recommended that the proposed 40 CFR 63.9621(d)(4) and 63.9631(j) be revised to allow the mass of taconite pellets produced to be determined indirectly through calculation based on industry standards. They noted that pellet mass is measured prior to offsite shipment and later “trued-up” at the end of each month.

                         The EPA agrees that taconite pellet production can be determined indirectly through calculation using bulk density and volume measurements. We have revised the language in 40 CFR 63.9621(d)(4) and 63.9631(j) to allow the weight of taconite pellets produced to be determined either by direct measurement using weigh hoppers, belt weigh feeders, or weighed quantities in shipments, or calculated using the bulk density and volume measurements.

                         Industry commenters stated that the capital and operating costs for Hg controls were underestimated in the proposal and that the estimated capital costs were significantly below cost estimates developed by industry. The commenters thought the retrofit factor of 1.2 used by the EPA failed to adequately account for the additional costs incurred when retrofitting an existing emission unit with new controls. They recommended the EPA use the capital costs prepared by industry and apply a retrofit factor of 1.5 or 1.6 with a contingency factor of 30 percent to account for the higher costs for retrofit projects. The commenters also stated that the total annual costs were underestimated because the EPA had underestimated costs for activated carbon, electricity, and waste disposal and used an interest rate that was too low. Industry commenters also stated that currently, some plants recycle iron particles collected by their particulate emission control device, but that the presence of activated carbon would create product quality issues and make recycling no longer possible. The commenters stated the EPA had not accounted for the loss of product and increased waste disposal costs in the cost estimates prepared for the proposal. The commenters provided cost estimates for the Keetac, Minorca, Minntac and UTAC facilities that included estimates of the amount of product they assert would be lost if scrubber solids are not recycled back through the process and the estimated price for the lost product. The commenters also disagreed with the estimated labor costs, arguing that both the number of operator hours and hourly labor rates were too low.

                         For the final rule, the EPA has updated the capital and annual costs to reflect the costs in 2023 dollars using an interest rate of 8.5 percent and updated unit prices for activated carbon, utilities, and labor. The EPA also assessed the commenters concerns that ACI would prevent plants from recovering iron particles collected with other solids by their particulate emission control device. Based on the information provided by industry, ten indurating furnaces currently collect the solids from their particulate control devices and recycle the solids back to the production process, thereby recovering valuable iron product. Commenters said plants using ACI would not be able to continue to recover iron in this way because carbon would impact the quality of their product. Commenters said EPA should account for costs due to the loss of product and increased cost of waste disposal of the unrecoverable product. Industry provided estimates of the amount of iron that would be lost for the furnaces located at the UTAC, Minorca, and Minntac plants. We used this data to estimate iron losses for the Hibbing plant and multiplied the estimated iron losses for each furnace by the current market price of iron to estimate the costs associated with the loss iron product. The updated cost estimates that we are using for the final rule, including the basis for the 8.5 percent interest rate, are documented in the memorandum,

                        The EPA reviewed the capital cost information submitted by industry during the comment period and found the information submitted consisted of a total capital cost for equipment. However, no breakdown was provided from which we could ascertain what was included in the cost and little information was provided on how the costs were derived. The lack of detail in the cost estimates combined with little supporting documentation made it impossible for the EPA to assess the accuracy of the cost estimates submitted by industry. Industry commenters indicated that the estimated equipment costs for the air pollution control equipment for the Minorca and UTAC facilities they submitted were estimated using cost data from another project at a different facility and scaled using the 
                        <PRTPAGE P="16412"/>
                        `rule of six-tenths.' The `rule of six-tenths' is a method by which equipment costs are estimated as the cost of a known project multiplied by a capacity factor raised to the power of six-tenths. The `rule of six-tenths' can provide a reasonable order of magnitude estimate of equipment costs where the capacities of the two systems are reasonably similar. However, the commenters did not identify the facility or provide a detailed description of the project to which they are applying the rule of six-tenths. Commenters also failed to provide a detailed breakdown of the equipment costs used in the `rule of six-tenths' estimate. Without additional information, the EPA was unable to assess the accuracy of the equipment costs provided by commenters. Therefore, we are not making any changes based on this information.

                        We disagree with the commenters' recommendations that a retrofit factor of 1.5 or 1.6 should be applied to the capital costs with a 30-percent contingency factor. Retrofit factors account for costs directly related to the demolition, fabrication, and installation of the control system. For the venturi scrubbers we included the 3-percent contingency factor and applied a retrofit factor of 1.2 to the estimate of the total capital investment for new construction. The EPA's 
                        <E T="03">Air Pollution Control Cost Manual</E>
                         indicates a 3-percent contingency factor is considered appropriate for a mature air pollution control technology and states that retrofit costs are “generally minimal” for venturi scrubbers because of their small footprint.

                        <FTREF/>
                         While we agree with the commenters that retrofits may, in some cases, be more expensive than new construction, the 1.2 retrofit factor used in the cost estimates provides a reasonable increase to account for the higher cost associated with retrofit projects that involve replacing an existing venturi scrubber with a high-efficiency venturi scrubber, where infrastructure (
                        <E T="03">e.g.,</E>
                         water and power supply) already exist. The retrofit factor applied does not have a significant impact on the total annual costs. If a retrofit factor of 1.6 is applied, as recommended by the commenters, the total annual costs would increase by about 2 percent (less than $2 million for replacing the venturi scrubbers on all 11 furnaces with mercury emissions currently exceeding the MACT floor. We did not apply a retrofit factor to the capital costs for the activated carbon injection (ACI) system because the costs were estimated using a methodology developed by Sargent &amp; Lundy for the EPA's Integrated Planning Model (IPM).

                        <FTREF/>
                         The IPM methodology is based on costs for retrofitting ACI on utility boilers and therefore already represents the average or typical costs for ACI retrofits.

Retrofit and contingency factors can be difficult to assess as they vary based on site-specific characteristics. Nevertheless, the EPA considers the methodology used to calculate capital and total annual costs to be a reasonable approach to estimating costs for the purposes of this rulemaking.

                         Industry commenters noted that the Hg concentrations in taconite ore deposits vary widely both within each mine and between mines, which in turn affects Hg emissions. The commenters said the primary source of Hg emissions from indurating furnaces is from the Hg contained in the greenballs (
                        <E T="03">i.e.,</E>
                         unfired taconite iron ore pellets). The commenters provided Hg concentration data for greenballs from each taconite iron ore processing facility and recommended that the EPA revise the proposed Hg limits for new and existing furnaces to address the variability inherent in the Hg concentration of greenballs. They suggested the EPA use the data to develop a raw material variability factor that could be used when calculating the MACT floor limits for Hg. The commenters noted that the EPA had accounted for variability in the Hg concentration of raw materials when calculating the MACT floor limits for other NESHAP.

                         The EPA reviewed the Hg data submitted by industry and determined the data were not adequate for us to calculate a variability factor for use in deriving the MACT floor limits. This decision was based on several factors. First, the number of measurements submitted for each facility varied considerably—from as few as three measurements for the best performing furnace at Northshore (including two measurements on the same day) to as many as 948 measurements for the UTAC plant. The very limited data provided for Northshore is a concern because Northshore's stack test data showed that their furnace was the best performing (
                        <E T="03">i.e.,</E>
                         had the lowest emissions of Hg). The data provided for Northshore are insufficient to evaluate temporal variability in the Hg content of the greenballs at Northshore because the data consist of measurements made during only two greenball sampling episodes: one in January 1997 and the other in November 2001. Second, much of the data submitted could not be validated because the commenters did not provide the laboratory reports for the test results. For example, the UTAC facility provided 948 measurements of the Hg concentration of the greenballs at their plant but submitted none of the laboratory reports needed to corroborate their data. Laboratory reports are needed to determine whether appropriate methods were used for sample collection and analysis, to confirm appropriate quality assurance and quality control measures were taken, and to check that the values submitted are accurate. In total, we were unable to confirm the concentration values for over 87 percent of the measurements submitted because we lacked the laboratory reports. Third, the samples were collected at irregularly spaced intervals, often with large gaps in time during which no samples were collected. These sampling intervals varied from as little as a few days to multiple years. In cases where samples were collected over a period of several consecutive months, the measurements were not collected at consistent intervals. Ideally, the samples would be collected at representative intervals with supporting documentation of the sample collection and analysis, to avoid bias in the dataset. Finally, the data submitted for some facilities included measurements that we determined to be statistical outliers. For example, we identified two statistical outliers in the Tilden dataset, where in one case the Hg content of greenballs increased from 1.4 nanograms per gram (ng/g) on July 6, 2022, to 15.0 ng/g on July 15, 2022, before decreasing to 1.2 ng/g on July 22, 2022. The presence of statistical outliers does not necessarily mean the 
                        <PRTPAGE P="16413"/>
                        measurements are incorrect. However, statistical outliers raise concerns over the accuracy and representativeness of the measurements, particularly where no explanation for the anomaly is available.

                         In response to the commenters' request, we reviewed EPA Method 30B and determined that this method is appropriate for measuring Hg emissions from indurating furnaces. In the final rule, we have updated the list of approved methods for Hg measurement to include EPA Method 30B, in addition to the proposed methods. The final rule allows owners and operators to use EPA Methods 29 or 30B in 40 CFR part 60, appendix A-8, and the voluntary consensus standard (VCS), ASTM D6784-16,

                         Industry commenters expressed concern that the proposed Hg stack testing volumes for performance testing to demonstrate compliance with the proposed Hg standards were too large such that each test run would require too much time to complete. They recommended that smaller test volumes would be appropriate and suggested that the test volume be small enough to allow each test run to be completed within 60 minutes.

                         In response to the commenters' concerns regarding the stack testing volumes and duration of each test run, the EPA reconsidered the proposed sample volume requirements and revised the performance testing requirements in the final rule to require a minimum sample volume of 1.7 dry standard cubic meters (dscm) (60 dry standard cubic feet (dscf)) for EPA Method 29 and ASTM D6784-16, instead of the 3 dscm sample volume we proposed. The 1.7 dscm sample volume will allow test runs to be completed in approximately 2 hours while still ensuring that the required sample volume is sufficient for analysis and that a non-detect test result indicates compliance with the final Hg limits.

                         We received multiple comments recommending continuous emission monitoring systems (CEMS) for Hg be included either as a requirement for all indurating furnaces or as an optional alternative to conducting performance testing and establishing operating limits. The commenters stated that CEMS would ensure continuous compliance with the Hg standard and could help lower compliance costs by making it possible for facilities to vary the ACI rate based on the Hg emissions data collected by CEMS. Some commenters said facilities would be more likely to use CEMS if the CEMS provisions were incorporated into the rule because facilities would not have to apply for approval of an alternative monitoring method.

                         The EPA agrees with recommendations made by commenters that suggested CEMS be included as an optional alternative to the proposed compliance monitoring and performance testing requirements. We agree that CEMS are an acceptable alternative monitoring method for assuring compliance with the Hg emissions standards. In the final rule, we have included provisions that provide owners and operators the option of using Hg CEMS in lieu of establishing operating limits and performing periodic performance testing. These provisions will provide more options for the methods that facilities can use to demonstrate compliance with the new Hg standards and reduce the burden associated with applying for Administrator approval of an alternative monitoring plan. However, we are not requiring installation of CEMS due to compliance cost considerations, as explained in the memorandum,

                         Industry commenters were concerned that the proposed approach to setting operating limits for ACI would not allow facilities flexibility to adjust the carbon injection rates when production decreases. These commenters suggested the EPA allow flexibility to adjust the average ACI rate and average carrier flow rate based on taconite pellet production rates during stack testing to provide facilities with the operational flexibility needed at lower production rates.

                         We agree with the industry commenters that lower ACI and carrier gas flow rates would achieve compliance with the emission limit when production rates are lower than the production rates during the performance test used to establish operating limits. We have included provisions in the final rule that allow a facility to adjust the operating limits based on taconite pellet production. Under the requirements of the final rule, a facility has the option of establishing operating limits for different production rates by conducting performance tests at the maximum, minimum, and median taconite pellet production rates of an indurating furnace to develop a relationship between the carbon injection rate and taconite pellet production rate. An owner or operator would monitor the taconite pellet production rate and adjust the ACI rate in accordance with the relationship between these parameters developed during the performance testing. If the taconite pellet production rate falls below the minimum rate measured during performance testing, the owners and operators must maintain a carbon injection rate that is equal to, or above, the rate determined during the performance testing completed at the minimum taconite production rate.
                    </P>
                    <P>As an alternative, an owner or operator may adjust the ACI rate based on the direct measurement of Hg emitted to the atmosphere.

                         Industry commenters supported the EPA's decision to set the Hg emissions standards at the MACT floor rather than setting a BTF standard. Industry commenters stated that the capital and annual costs required to comply with the MACT floor are too high and setting BTF standards would not be cost-effective. One commenter asserted that any standard beyond the MACT floor must be justified by a “thorough and robust analysis of the costs and benefits.” The commenter agreed with the EPA's proposed determination that the cost-effectiveness of the BTF options identified for Hg control were above the level historically found to be reasonable.

                        Several other commenters recommended the EPA set a BTF Hg standard and recommended the standard be at least 30-40 percent more stringent than the MACT floor. The commenters stated that additional Hg reductions can be achieved and that a more stringent Hg standard is warranted due to the bioaccumulative nature of Hg. The commenter noted that many water bodies located near taconite facilities already have fish consumption advisories, which commenters noted impact the rights of tribes to exercise their traditional life practices. One commenter noted that tribes have a particular interest in Hg emissions due to the Hg-related fish consumption advisories that have been issued by Minnesota since the 1970s and by the Fond du Lac Tribe beginning in 2000. One commenter stated that the 30

                        percent BTF option would reduce Hg emissions to a level that would help address public health concerns associated with high concentrations of Hg in water, fish tissues, and other subsistence resources. Commenters from several tribes located near taconite facilities stated that the EPA's Tribal trust and treaty responsibilities justified adoption of a BTF option. They added that the EPA should consider its trust responsibility to protect the interests of tribes and the tribes' treaty rights and quoted from two EPA policy documents: 
                        <E T="03">EPA Policy for the Administration of Environmental Programs on Indian Reservations</E>

Commenters noted that the areas impacted by taconite iron ore processing plants are in the areas covered by a series of treaties. These commenters disagreed with the EPA's determination that BTF options were not cost-effective.

                         The EPA agrees with the commenters that said the Hg standard should be set at the MACT floor. In our analysis, the BTF options were above the numbers we have found cost effective for Hg controls in prior CAA section 112 rulemakings.

                        The EPA recognizes the Federal government's trust responsibility, which derives from the historical relationship between the Federal government and Indian Tribes. The EPA acts consistently with the Federal government trust responsibility by implementing the statutes it administers and consulting with and considering the interests of tribes when taking actions that may affect them. As we noted in the proposal, the EPA consulted with Tribal government officials during the development of this rule. The EPA's Office of Air and Radiation held a meeting with the Fond du Lac Band of Lake Superior Chippewa Reservation and the Leech Lake Band of Ojibwe Reservation on January 12, 2022, to discuss the EPA's CAA section 114 information request, and to ensure that the views of affected tribes were taken into consideration in the rulemaking process in accordance with the

                        The Agency recognizes the concerns raised by numerous Tribal commenters regarding impacts to treaty fishing and other resource rights. However, for the reasons explained below, the EPA is declining to set BTF standards for Hg, based on the statutory factors that we are required to consider pursuant to CAA section 112(d)(2) when assessing whether to set MACT standards more stringent than the MACT floor level of control. These statutory factors include the cost of achieving such emission reduction, and any non-air quality health and environmental impacts and energy requirements. As discussed in paragraphs later in this section, the cost-effectiveness values associated with BTF standards for this Taconite Iron Ore Processing rule are well above the cost-effectiveness values that EPA has historically accepted when considering BTF options for regulating mercury emissions. We note that the historic acceptable cost-effectiveness values for mercury (
                        <E T="03">e.g.,</E>
                         up to $22,400 per pound [in 2007 dollars] in the 2011 final MATS rule, which equates to about $32,000 per pound in current dollars) are much higher than the cost-effectiveness values we have accepted for all other HAPs (except for maybe a few exceptions such as dioxins and furans) and is based, at least in part, on the fact that mercury is a persistent, bioaccumulative, toxic (PBT) HAP. Nevertheless, we conclude that setting BTF Hg standards in this rule would be inconsistent with the values found to be cost-effective for Hg controls in prior rulemakings. We are declining to set BTF standards in this rule based on cost and other statutory factors.
                    </P>
                    <P>Section 112(d) of the CAA requires the EPA to set emissions standards for HAP emitted by sources in each source category and subcategory listed under CAA section 112(c). The MACT standards for existing sources must be at least as stringent as the average emissions limitation achieved by the best performing 12 percent of existing sources (for which the Administrator has emissions information) or the best performing five sources for source categories with less than 30 sources (CAA sections 112(d)(3)(A) and (B)). This level of minimum stringency is called the MACT floor. For new sources, MACT standards must be at least as stringent as the control level achieved in practice by the best controlled similar source (CAA section 112(d)(3)). The EPA may not consider costs or other impacts in determining the MACT floor.</P>
                    <P>
                        Section 112(d)(2) of the CAA also requires the EPA to examine emission standards more stringent than the MACT floor, which the EPA refers to as BTF control options. Unlike standards set at the MACT floor level of control, when assessing whether to require emission standards more stringent than the MACT floor, the EPA must consider the cost of achieving such emission reduction, and any non-air quality health and environmental impacts and energy requirements. The EPA's BTF analysis evaluated these factors in determining whether to establish Hg standards more stringent than the MACT floor. In developing this final rule, we evaluated Hg emission limits more stringent than the MACT floor after adjusting estimates of Hg emissions, Hg emission reductions, and control costs as discussed above, including those BTF limits suggested by commenters, to assess whether a BTF option was technically achievable and cost-effective. We estimate that the total capital costs and total annual costs would range from a low of $137 million and $92 million, respectively, for a limit that is 10 percent more stringent than the floor to a high of $148 million and $102 million, respectively, for a limit that is 40 percent more stringent than the floor. The incremental cost effectiveness for the BTF options examined varied from a low of $46,266 per pound of Hg reduced for 30 percent more stringent than the floor to a high of $91,140 per pound of Hg reduced for 40 percent more stringent than the floor. These values are well above the $/pound of Hg reduced that we have historically found to be cost-effective when considering BTF options for regulating Hg emissions. Where EPA has taken costs into account, the Agency has finalized standards for mercury with cost effectiveness estimates of up to $32,000/lb Hg reduced (adjusted to 2024 dollars). See Mercury Cell Chlor-Alkali Plants Residual Risk and Technology Review (87 FR 27002, May 6, 2022); 2011 Mercury and Air Toxics (MATS) final rule. To date, these are the highest cost-effectiveness values that we have accepted in the air toxics program for any HAP (except for maybe a few exceptions such as dioxins and furans), largely because of the toxicity and nature of Hg. While we conclude that mercury standards more stringent than the MACT floor are not cost-effective, we note that as a result of the revisions to the rule being finalized in this rulemaking, we will receive compliance test information that will allow us to evaluate our conclusions and potentially inform appropriate future

                        regulatory activities including the next statutorily required technology review. Mercury is one of the high concern HAPs because it is environmentally persistent, it bioaccumulates in humans and food chains—including in fish, which is a concern for subsistence needs, uses and cultural practices as noted in multiple comments from Tribes—and is a neurotoxin that is especially of concern for developing fetuses and young children. For these reasons, mercury is one of the few HAPs for which we use the expression of $ per pound and consider higher cost-effectiveness values. We also estimated the secondary impacts of the BTF options would range between 155,000 megawatt-hours per year (MWh/yr) and 160,000 MWh/yr of electricity (with associated secondary air emissions), generate between 4.7 million and 7.4 million gallons of wastewater per year, and produce between 110,000 tons and 112,000 tons of solid waste of per year. Based on our assessment of Hg emission standards 10 percent, 20 percent, 30 percent, and 40 percent more stringent than the MACT floor, including consideration of cost and other statutory factors of setting BTF Hg standards for indurating furnaces in the source category as specified in CAA section 112(d)(2), in the final rule, we are declining to adopt BTF emission standards for Hg and are finalizing Hg standards at the MACT floor as discussed in section III.A.3 of this preamble.

                         Several commenters, including the National Park Service, several local tribes, and environmental organizations said Hg standards for the taconite industry were important because of the benefits lower Hg emissions will have on public health and the environment. One commenter cited several studies, such as the Dragonfly Mercury Project, that document elevated levels of Hg and higher risks of Hg exposure to humans and wildlife in the Great Lakes Region. This commenter stated that the upper Great Lakes Region is particularly sensitive to Hg pollution due to the abundance of wetlands and peatlands, low-pH lakes, high dissolved organic matter, low biological productivity, and other factors that provide conditions suitable for the conversion of Hg to the bioavailable form methylmercury. The commenter also stated the impacts of Hg on wildlife include reduced foraging efficiency, lower reproductive success, impaired endocrine modulation, and damage to kidney and other tissues. The commenters expressed concern over the number of fish with Hg levels exceeding the human and wildlife health thresholds. The commenter cited data from a 1998-2016 study that measured Hg concentrations in fish from the upper Great Lakes at 0.12 ppm wet weight, with 24 percent of the fish sampled exceeding the EPA human health criterion of 0.3 ppm wet weight, 27 percent of the fish exceeding fish-eating wildlife health threshold of 0.2 ppm whole-body, and 17 percent exceeding the fish toxicity benchmark of 0.3 ppm whole-body. This commenter cited studies linking Hg deposition with bioaccumulation, including a study of Hg concentration in moose teeth from Isle Royale National Park, Michigan from 1952 to 2002. The commenter noted that Hg decreased by about two-thirds during the early 1980s but remained constant for the following 2 decades. The commenter cited an additional six studies that analyzed the concentrations and trends of Hg in bald eagle nestlings in the upper Midwest from 2006-2015 and long-term trends at two Lake Superior sites between 1989-2015. These studies show concentrations of Hg in nestling breast feathers were highest at the Saint Croix National Scenic Riverway (6.66 µg/g wet weight) and that Hg concentrations have increased at two other study area sites.

                    <P>The commenters said the new Hg standards will help reduce Hg deposition in the Great Lakes Region and improve public health. The commenters asserted that taconite iron ore processing plants in Minnesota and Michigan have a significant impact on the natural resources of the upper Great Lakes Region and the elevated Hg levels in fish and bird populations. Several commenters mentioned the statewide fish consumption advisories for Hg in Minnesota, Michigan, and Wisconsin and noted several water bodies in these states are listed as impaired for aquatic consumption due to Hg. The commenters asserted that the new Hg standards will reduce the impact of Hg on public health and the environment, provide additional protection to recreational and subsistence fish consumers in national parks and surrounding communities, and protect natural resources that are of cultural significance to many local communities.</P>

                         The EPA acknowledges the independent research conducted by the National Park Service and others on the impacts of Hg on the communities and wildlife of the upper Great Lakes Region. We share the commenters' concern about the elevated Hg levels in fish and other wildlife in Minnesota, Wisconsin, and Michigan, and the critical impact these Hg levels have on tribes and low-income populations that rely on the fish and wildlife from the Great Lakes region. By controlling Hg emissions, the Hg MACT standards EPA is finalizing in this action for taconite iron ore processing plants will achieve an estimated reduction of 247 pounds per year of mercury emissions from the Taconite facilities, which we expect will also achieve an unquantified reduction of Hg deposition in the Great Lakes Region and therefore improve public health of local communities, including local tribes and low-income populations.

                        Owners and operators may demonstrate compliance with the new Hg standards in one of two ways. Under the first option, an owner or operator may demonstrate compliance by completing performance testing and establishing operating limits for each control device used to comply with the Hg standard. The final rule clarifies that performance testing must be performed when the production rate is equal to or greater than 90 percent of the capacity of the indurating furnace. If the performance testing cannot be performed when the production rate is equal to or greater than 90 percent of the production rate capacity of the furnace, the owner or operator may complete testing at a lower production rate if they receive approval from the delegated authority. An owner or operator selecting this option must install and operate continuous parameter monitoring systems (CPMS) to monitor the parameters specified in 40 CFR 63.9631(g). An owner or operator must take corrective action when an established operating limit is exceeded.

In the May 15, 2023, proposal, we proposed to revise the HCl and HF standards based on new information we obtained in response to the 2022 information collection concerning emissions of these pollutants from the source category.

                         lb/LT for HCl and 1.2 × 10

                         lb/LT for HF. For new indurating furnaces, we proposed emission standards of 4.4 × 10

                         lb/LT for HF. We proposed to require that owners or operators demonstrate compliance through initial and periodic performance testing (completed at least twice per 5-year permit term), establishing operating limits for each control device used to comply with the HCl and HF standards, and installing and operating continuous parameter monitoring systems (CPMS) to ensure continuous compliance with the standards.

                         We received comments and data from industry identifying errors in the emissions data for the Tilden and Hibbing indurating furnaces submitted to the EPA in response to the CAA section 114 information request sent to the taconite facilities in 2022. For the Tilden stack test report, industry confirmed the units of measure were incorrectly listed in the stack test report submitted by industry as “pounds per ton” instead of “pounds per long ton” of taconite pellets produced. Commenters confirmed the units of measure should be “pounds per long ton.” For Hibbing, the commenters identified one transcription error in the HCl emissions data for one of the four emission stacks.

                         In response to these comments, the EPA reviewed all stack test runs for the seven furnaces that completed HCl and HF stack testing pursuant to the 2022 CAA section 114 information request. We confirmed there was a transcription error in HCl emissions for the first run of the stack testing completed on the Hibbing furnace. Since the emissions data for Hibbing were included in the dataset used to calculate the proposed HCl emission limit, we recalculated the emission limit for HCl using the revised data. As a result of the changes to the Hibbing emissions data, the numerical emission standard for HCl for existing sources was revised from the proposed 4.4 × 10

                         lb/LT limit we are finalizing in this action. The revisions to the emissions data do not impact the numerical limit for HCl for new sources or the numerical limits for HF for new and existing sources. Therefore, the proposed HCl standard for new sources of 4.4 × 10
                        <E T="51">−4</E>
                         lb/LT and the HF standards for new and existing sources of 3.3 × 10

                        The EPA revised the units of measure for the Tilden HCl and HF emission data based on the comments we received from industry. As we explained in the proposal, the HCl and HF emissions data for the Tilden furnace are not used to calculate the emission limits for HCl and HF because Tilden's furnaces use dry electrostatic precipitators (ESP). In the proposal, we stated that we expect Tilden's two indurating furnaces would be able to meet the HF limit for existing furnaces without adding any air pollution control devices but that we expect Tilden would be required to add air pollution control devices to meet the proposed HCl emission standard. Although the revised emission rates for Tilden are slightly lower than the emissions rates used for the proposal, we expect that Tilden's furnaces would still need to add air pollution controls to meet the HCl emission standard we are finalizing for existing furnaces. As explained in the previous paragraph, the EPA is finalizing the HCl emission standard of 4.6 × 10
                        <E T="51">−2</E>
                         lb/LT for existing sources. To comply with the HCl emission standard, Tilden must reduce HCl emissions by 76 percent (compared to 79 percent HCl reduction we estimated at proposal) and the HCl emissions reduction for the final rule is 683 tpy (compared to a 713 tpy reduction we estimated at proposal). Our revised total capital cost estimate for HCl controls (dry sorbent injection) is $1.1 million and our revised annual cost estimate is $1.4 million. The revised cost effectiveness is $2,040 per ton of HCl removed, which is a level of cost effectiveness that is acceptable for HCl and would also likely be acceptable for any other HAP. The revised emissions data, numerical limits, and cost estimates prepared for the final rule are documented in the memorandum,

                         Multiple commenters were supportive of replacing PM as a surrogate for HCl and HF emissions and supported the proposed numerical emission limits for HCl and HF. One commenter said the PM limit was not a valid surrogate for emissions of HCl and HF and argued the EPA should set HCl and HF limits under the provisions of CAA section 112(d)(2) and (3). However, other commenters from industry disagreed with our proposal and said the existing standards based on PM as a surrogate for acid gases should not be changed. These commenters asserted that the EPA lacked the authority to revise the existing HCl and HF standards because the EPA had not shown that technological developments have occurred that would lower emissions of acid gases nor shown that revisions are necessary, as required by CAA section 112(d)(6). The commenters stated that new emissions data does not qualify as a development under CAA section 112(d)(6) and that the language in CAA section 112(d)(6) focuses on actual control measures and requires the EPA to update an existing emissions standard only if improvements in control measures occur and the improvements in control measures warrant a revision. The commenters added that PM is still recognized as a proper surrogate for HAP emissions and the revised standards are unnecessary because they impose a significant financial burden on taconite iron ore processing plants without reducing risks to the public health and the environment.

                         The EPA agrees that revising the emission limits for HCl and HF is appropriate for the reasons explained in this discussion, below, and in the proposal preamble (88 FR 30926). We disagree that the EPA lacks authority to revise the existing standards for HCl and HF. When the NESHAP for the Taconite Iron Ore Processing source category was first developed, PM emission limits were used as a surrogate for HCl and HF. The decision to use the PM standards as a surrogate for HCl and HF emissions was based on an analysis of the HCl, HF, and PM emissions data that the EPA possessed at the time of promulgation of the initial NESHAP for the Taconite Iron Ore Processing source category in 2003 (68 FR 61868; October 30, 2003). That data indicated there was a correlation between acid gas and PM emissions. We note, however, that the use of PM as a surrogate for HCl and HF and the corresponding PM emission limit were based on a limited dataset because only three furnaces conducted PM emissions tests concurrently with the HCl and HF tests. As part of the 2022 CAA section 114 information request, the EPA sought emissions data from Taconite Iron Ore Processing facilities, including stack testing for PM, HCl, and HF emissions from seven indurating furnaces located at six taconite facilities. The data received in response to the 2022 CAA section 114 information request are presented in the memorandum, 
                        <E T="03">Final Emissions Data Collected in 2022 for Indurating Furnaces Located at Taconite Iron Ore Processing Plants,</E>
                         which is available in the docket for this action. The 2022 dataset is not only more robust than the limited dataset available in 2003 but also more representative of current conditions since some of the control devices used on the furnaces at the time of the 2003 rulemaking have changed since that time. For example, the Keetac plant has since replaced the multicyclones on their indurating furnace with venturi scrubbers and the Tilden plant replaced a wet ESP on one stack with a dry ESP. Based on this new data, we determined it was more appropriate to directly regulate the HAP of concern than to use a surrogate. Our analysis of the 2022 data and our review of available air pollution controls for acid gases indicates that the controls we expect will be necessary to meet the numerical standards for HCl and HF are available and cost-effective. As we explained in the proposal (88 FR 30926), the new data received in response to the 2022 CAA section 114 information request showed that indurating furnaces using wet scrubbers achieve better control of HCl and HF than furnaces using dry ESP.
                    </P>
                    <P>We disagree with commenter that we lack the authority to revise standards pursuant to CAA section 112(d)(6) absent a showing that the revisions would reduce risk. CAA section 112(d)(6) requires the EPA to review and revise as necessary emission standards taking into account developments in practices, processes, and control technologies. This provision does not require the EPA to consider risk. We agree that the EPA has the discretion to consider cost when considering the appropriate level of control under CAA section 112(d)(6). The EPA identified dry sorbent injection (DSI) and wet scrubbers as a feasible control options and estimated the associated costs. We concluded that DSI is the lowest cost option for the indurating furnaces located at the Tilden plant. Based on this analysis, the EPA concluded the costs to comply with the numerical limits for HCl were justified and cost-effective and do not impose a significant financial burden on industry. The cost effectiveness was estimated to be $2,040 per ton of HCl removed, which is within the range the EPA has previously considered to be a cost-effective level of control for many HAP. Based on the 2022 emissions data, add on air pollution controls are not required to meet the HF emission limit. The standards we are finalizing in this action ensure HCl and HF emissions from all indurating furnaces in the source category are controlled to the same extent as the best performing indurating furnaces in the source category.</P>

                        <E T="03">Comment:</E>
                         Industry commenters stated there is no basis for changing the way HCl and HF emissions are regulated, that the EPA did not explain why PM cannot be used as a surrogate for HCl and HF emissions, and that if revised standards were needed, they should be based on the subcategories established in the Taconite Iron Ore Processing NESHAP in 2003. The commenters stated that the EPA should make determinations on whether new standards are necessary for each subcategory and then should base any new standards for each subcategory on emission data for the furnaces within that subcategory. The commenters acknowledged that CAA section 112(d)(6) authorizes the EPA to review and revise as necessary the emission standards every 8 years, but they said the statute does not permit the EPA to develop new standards ignoring the existing subcategories. The commenters argued the Tilden facility processes a different type of taconite ore (
                        <E T="03">i.e.,</E>
                         hematite instead of magnetite) than the other facilities and therefore the furnaces at this facility should remain in a separate subcategory from the furnaces at the other facilities (as was the case when the EPA established the PM standards in the 2003 NESHAP). The commenters noted that a subcategory was established for grate kilns processing hematite ore because of differences in the ore and furnace, including different air flow direction and rates, the perpetual motion of the pellets inside the kiln, fineness of the hematite ore, tendency for the hematite pellets to break, and production of fluxed pellets that use limestone/dolomite containing chloride. For furnaces that process magnetite, the commenters argued that limits for HCl and HF are not needed and would result in unnecessary compliance costs

                         We disagree with the industry commenters' assertion that the EPA should extend the subcategorization for PM standards used in the 2003 rulemaking and set HCl and HF limits only for grate kilns processing hematite ore. When the NESHAP for the Taconite Iron Ore Processing source category was initially developed, indurating furnaces were identified as significant sources of HCl and HF emissions. The NESHAP promulgated in 2003 established limits, as required under CAA section 112(d), for all indurating furnaces. The decision to use the PM standards as a surrogate for HCl and HF emissions was based on very limited HCl, HF, and PM emissions data available and evaluated for the 2003 rulemaking. As we explained in the response to the previous comment, in this action, we have determined it is more appropriate to directly regulate the HAP of concern (
                        <E T="03">i.e.,</E>
                         HCl and HF) than to use a surrogate, using the more robust 2022 dataset now available to us. The data collected for this rulemaking are presented in the memorandum, 
                        <E T="03">Final Emissions Data Collected in 2022 for Indurating Furnaces Located at Taconite Iron Ore Processing Plants,</E>

                        We disagree with commenters' assertion that emission limits for acid gases should be established using the existing subcategories for PM and that HCl and HF standards are not necessary for furnaces that process magnetite ore. The EPA found in the 2003 NESHAP final rule that HCl and HF are emitted by all indurating furnaces and established standards for all types of indurating furnaces in the Taconite Iron Ore Processing source category, including those indurating furnaces that process magnetite ore. Indeed, the emissions data collected in response to the 2022 CAA section 114 information request demonstrate that indurating furnaces processing magnetite ore emit measurable levels of HCl and HF even after control by wet scrubbers. HCl and HF are formed in indurating furnaces due to the presence of chlorides and fluorides in the raw materials used to form the greenballs (
                        <E T="03">i.e.,</E>
                         unfired taconite pellets) that are fed into the indurating furnaces. While some of the chlorides and fluorides in the raw materials come from the ore, pellet additives, such as dolomite and limestone, are also a source of HCl and HF emissions. These additives are routinely used by all taconite plants, including those that process magnetite ore. Although the commenters suggested plants processing hematite ore using grate-kilns should be considered a separate subcategory when considering acid gas emissions, the commenters provided no data demonstrating a significant difference in the chloride and fluoride content of the two types of ores. Nor did they provide any explanation or data to support their assertion that differences in the design of the indurating furnace impact HCl and HF emissions. The data pertaining to indurating furnaces processing magnetite ore that was collected in response to the 2022 CAA section 114 information request does not show a significant difference in acid gas emissions between straight-grate and grate kiln indurating furnaces.

                        Pursuant to CAA section 112(d)(1), the Administrator “may distinguish among classes, types, and sizes of sources within a category or subcategory in establishing” standards. However, as we have discussed in previous Agency actions, the CAA does not mandate that the EPA create subcategories. See, 
                        <E T="03">e.g., National Emission Standards for Hazardous Air Pollutants From Coal- and Oil-Fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial-Commercial-Institutional Steam Generating Units</E>
                         (77 FR 9304, 9378; February 16, 2012) (“2012 Mercury and Air Toxics Final Rule”). In addition, the Agency may create subcategories for the purpose of regulating specific HAP, while declining to create subcategories more broadly. In the 2012 Mercury and Air Toxics Final Rule, we explained the Agency's position that any basis for subcategorization (
                        <E T="03">i.e.,</E>
                         class, type, or size) typically must be related to an effect on HAP emissions that is due to the difference in class, type, or size of the sources. We further explained that “[e]ven if we determine that emissions characteristics are different for units that differ in class, type, or size, the Agency may still decline to subcategorize if there are compelling policy justifications that suggest subcategorization is not appropriate” (77 FR 9378). In the 2012 Mercury and Air Toxics Final Rule, we determined it was appropriate to subcategorize coal-fired boilers for purposes of regulating Hg emissions based on differences in Hg emissions between two types of coal-fired boiler subcategories. We also determined that for all other HAP, the data did not show any difference in HAP emission levels, and we declined to set separate emission standards for the two types of coal-fired boilers for other HAP.
                    </P>
                    <P>In this final rule, we are retaining the separate PM emission limits established in the 2003 final rule for indurating furnaces processing magnetite and hematite. Based on the data available, we continue to believe it is appropriate to retain these separate PM emission standards because hematite is a finer grained ore than magnetite, and processing of hematite in an indurating furnace results in higher PM emissions than processing magnetite. However, we are declining to subcategorize taconite indurating furnaces for purposes of regulating Hg or acid gas emissions. As explained previously, pursuant to CAA section 112(d)(1), the EPA has the discretion to subcategorize sources for the purpose of setting emission standards under CAA section 112, but is not required to do so. As we also explained, where the EPA elects to subcategorize sources, we typically do so for the purpose of setting standards for specific HAP where the basis for the subcategorization is related to an effect on HAP emissions that is due to a difference in class, type, or size of the sources. The differences in emissions of HCl and HF among taconite indurating furnaces are largely the result of differing controls utilized by sources rather than a result of the class, type, or size of the indurating furnaces themselves. Therefore, we conclude that the differences in HCl and HF emissions are not due to differences in the class, type, of size of taconite indurating furnaces. As a result, we do not believe it is appropriate to subcategorize taconite indurating furnaces for the purpose of regulating Hg, HCl, or HF emissions and are declining to do so in this final rule.</P>

                        Based on the data available, the EPA proposed to set HCl and HF emission standards that apply to all indurating furnaces. In this action, we are finalizing emission standards for HCl and HF as discussed in section III.B.1 of this preamble. While the HCl emission standard for existing furnaces differs from what we proposed for the reasons explained in section III.B.2 of this preamble, we continue to believe it is appropriate to set numerical emission standards for HCl and HF based on the 2022 ICR data rather than to continue to rely on PM standards as a surrogate for these pollutants. While we expect that most indurating furnaces will be able to meet the revised HCl and HF limits using existing air pollution controls, the new performance testing and parametric monitoring requirements are necessary to ensure continuous compliance with the HCl and HF emission standards. The

                        PM testing and monitoring requirements in the current NESHAP designed to ensure compliance with the PM emission standards, which will remain in place as surrogates for non-Hg metal HAP, are not sufficient to demonstrate compliance with the HCl and HF emission standards. Each owner and operator must complete performance testing, establish operating limits for each control device used to control HCl and HF, and monitor the appropriate parameters to demonstrate the control device is operating in a manner that ensures compliance with the HCl and HF emission standards. Performance testing must be completed at least twice per 5-year permit term and within 180 days of startup of new furnaces.

                         Industry commenters asserted the data used to develop the numerical standards for HCl and HF was too limited to reflect the operational and seasonal variability in the HCl and HF emissions. They stated that several factors influence the HCl and HF emissions and that the emissions data received in response to the 2022 CAA section 114 information request covers too short of a time period to be representative of the acid gas emissions from indurating furnaces. The commenters noted that HCl and HF emissions are driven by the chloride or fluoride content in the iron ore and that the limited dataset does not account for the full range of variability in the chlorine and fluorine content of raw materials. They stated that the raw materials vary throughout a taconite mine, producing raw materials with different compositions and characteristics that are not reflected in the 2022 CAA section 114 information request data. The commenters recommended the HCl and HF limits be based on a more representative dataset collected over a longer period of time that accounts for raw material variation as well as seasonal and operational variation. The commenters stated that because the proposed limits are based on a limited dataset that does not fully account for operational variability, the proposed HCl and HF emission limits should not be finalized and they recommended that the PM standards in the current NESHAP continue to be used as a surrogate for acid gas emissions.

                         The method used to calculate the proposed numeric emission limits for HCl and HF for new and existing taconite indurating furnaces has been used for several years to set numerical limits for other source categories and is an appropriate methodology that accounts for variability in the emissions between different furnaces and different plants and accounts for some variability in the chloride and fluoride content of the ore and pellet additives used at different facilities because it includes data from two different types of indurating furnaces (straight grate furnaces and grate kiln furnaces) at five different taconite facilities. We used the emissions data from the six indurating furnaces currently using wet scrubbers to calculate a UPL. The UPL approach encompasses all the data point-to-data point variability within the sample set (
                        <E T="03">i.e.,</E>
                         all of the emissions data from the six indurating furnaces equipped with wet venturi scrubbers), which consisted of 21 individual data points. The UPL was calculated as the mean of the 21 data points plus a factor that accounts for the variability within the dataset. The UPL represents the value which one can expect the mean of a specified number of future observations (
                        <E T="03">e.g.,</E>
                         3-run average) to fall below at a specified level of confidence based upon the results of an independent sample from the same population. We used a 99-percent level of confidence to calculate the UPL, which means that a facility that uses the same or similar type of air pollution control device(s) has one chance in 100 of exceeding the emission limit. A prediction interval for a single future observation (or an average of several test observations) is an interval that will, with a specified degree of confidence, contain the next (or the average of some other pre-specified number of) randomly selected observation(s) from a population. The UPL estimates what the upper bound of future values will be based upon present or past background samples taken. While larger datasets are always preferable, numerical emission limits are often based on data from a single stack test event.

                        We are finalizing numerical emission limits for HCl and HF, pursuant to CAA section 112(d)(6). We are finalizing as proposed the numerical emission limit for HCl for new indurating furnaces. We are finalizing a numerical emission limit for HCl for existing indurating furnaces which differs from the limit proposed because the final limit reflects a revision to the emissions data for the Hibbing facility, as discussed in section III.B.2 of this preamble. We are finalizing as proposed the numerical emission limits for HF for new and existing indurating furnaces. For existing indurating furnaces, we are finalizing an HCl emission limit of 4.6 × 10

The final rule clarifies that the owner or operator must perform performance testing when the pellet production rate is equal to or greater than 90 percent of the capacity of the indurating furnace. If the performance testing cannot be performed at or above 90 percent of capacity of the indurating furnace, the owner or operator may complete testing at a lower production rate if they receive approval from the delegated authority. The owner or operator must install and operate CPMS in accordance with the requirements of 40 CFR 63.9633 and must prepare a preventive maintenance plan and keep records of calibration and accuracy checks of the CPMS to document proper operation and maintenance of each monitoring system. An owner or operator must take corrective action when an established operating limit is exceeded. The owner or operator must complete the initial performance tests within 180 calendar days of the compliance date for existing furnaces, or within 180 calendar days of startup for new furnaces. The performance tests must be repeated at least twice per 5-year permit term.

                    <P>The EPA proposed amendments to the performance testing provisions that would require the owner or operator to complete a performance test on a source within 7 calendar days of initiating that performance test. This provision was included for the existing performance testing for PM, as well as for the proposed new performance testing for Hg, HCl, and HF. We received one comment that resulted in changes to the proposed requirements. The comment and our response are summarized below.</P>

                        <E T="03">Comments:</E>
                         Industry commenters opposed the proposed requirement that all performance testing be completed within 7 calendar days because some emission sources have multiple stacks and testing of multiple stacks could require more than 7 days to complete. They also stated that unanticipated shutdowns due to process upsets may prevent tests from being completed within 7 days. The commenters recommended that the EPA allow facilities to notify the Administrator when a longer time frame is needed but asserted that facilities should not be required to obtain approval if more than 7 calendar days are needed to complete performance testing.

                    <P>
                        <E T="03">Response:</E>
                         We consider the 7 calendar day period to complete all performance testing to be reasonable based on our previous experience with performance testing at industrial facilities. We believe it is unlikely that a facility would be unable to complete the required performance testing within a 7 calendar day timeframe. However, we acknowledge the commenters' concerns that unanticipated shutdowns can occur due to equipment failures or process upsets. To address such circumstances, we included the phrase “to the extent practicable” in the final rule. We have finalized the proposed requirement that performance tests be completed within 7 calendar days of the date on which the first test run was started. However, we agree with the commenters' suggestion that owners and operators be required to notify the Administrator when a performance test cannot be completed within 7 calendar days. In the final rule, we revised the proposed language in 40 CFR 63.9620(b)(2), 63.9620(k)(2), and 63.9630(b) to require facilities that will not be able to complete performance tests within 7 calendar days to notify the Administrator within 24 hours of making the determination that they will not be able to do so.

For all affected sources that commence construction or reconstruction before May 15, 2023, we are finalizing, as proposed, that an owner or operator must comply with the new Hg emission standard and revised HCl and HF standards no later than 3 years after the effective date of the final rule. For all affected sources that commenced construction or reconstruction on or after May 15, 2023, we are finalizing, as proposed, that owners and operators comply with provisions by the effective date of the final rule or upon startup, whichever is later. For existing sources, CAA section 112(i)(3) requires compliance “as expeditiously as practicable, but in no event later than 3 years after the effective date of such standard” subject to certain exemptions further detailed in the statute.

                         In determining what compliance period is as “expeditious as practicable,” we examine the amount of time needed to plan and construct projects and change operating procedures. Since some existing sources may need to install new add-on controls to comply with the Hg, HCl, and/or HF standards, we determined that a period of 3 years is appropriate to allow owners and operators time to plan, design, construct, begin operating the new add-on controls, and conduct performance testing.

                    <HD SOURCE="HD2">A. What are the affected sources?</HD>
                    <P>The Taconite Iron Ore Processing NESHAP applies to the owner or operator of a taconite iron ore processing plant that is (or is part of) a major source of HAP emissions. A taconite iron ore processing plant is any facility engaged in separating and concentrating iron ore from taconite ore to produce taconite pellets. Taconite iron ore processing includes the following processes: liberation of the iron ore by wet or dry crushing and grinding in gyratory crushers, cone crushers, rod mills, and ball mills; concentration of the iron ore by magnetic separation or flotation; pelletizing by wet tumbling with a balling drum or balling disc; induration using a straight grate or grate kiln indurating furnace; and finished pellet handling. A major source of HAP is a plant site that emits, or has the potential to emit, any single HAP at a rate of 9.07 megagrams (10 tons) or more, or any combination of HAP at a rate of 22.68 megagrams (25 tons) or more per year from all emission sources at the plant site. There are currently seven major sources subject to the Taconite Iron Ore Processing NESHAP that are operating in the United States with six located in Minnesota and one located in Michigan. One additional major source located in Michigan, Empire Mining, is subject to the Taconite Iron Ore Processing NESHAP and has a permit to operate but has been indefinitely idled since 2016.</P>
                    <HD SOURCE="HD2">B. What are the air quality impacts?</HD>
                    <P>To meet the Hg emission limits we anticipate that five of the taconite iron ore processing plants would likely need to install additional controls on their indurating furnaces. To meet the HCl and HF emission limits, we anticipate that one additional taconite iron ore processing plant would likely need to install additional controls on their indurating furnaces. We estimate that the installation of such controls will reduce Hg emissions by 247 pounds per year (0.12 tpy) and HCl and HF emissions by 683 tpy and 36 tpy, respectively.</P>
                    <P>
                        Indirect or secondary air emissions impacts are impacts that would result from the increased electricity usage associated with the operation of control devices (

This rule is also expected to reduce emissions of Hg. Methylmercury (MeHg), which is formed by microbial action in the top layers of sediment and soils, after mercury has precipitated from the air and deposited into waterbodies or land, is known to cause a number of adverse effects. Though not quantified here, these effects include IQ loss measured by performance on neurobehavioral tests, particularly on tests of attention, fine motor-function, language, and visual spatial ability.

                        We estimate the total capital and annualized costs of this final rule for existing sources in the Taconite Iron Ore Processing source category will be approximately $106 million and $68 million per year, respectively. The annual costs are based on operation and maintenance of added control systems. Although this action also finalizes standards for new sources, we are not aware of any new sources being constructed now or planned for the future. No new indurating furnaces have been constructed, reconstructed or modified in more than a decade and the domestic demand for taconite pellets has decreased over the past several decades caused by the increasing use of electric arc furnaces.

                    <P>The EPA assessed the potential economic impacts of this action by comparing the expected annual cost for operating the air pollution control devices to the total sales revenue for the ultimate owners of affected facilities. The expected annual cost is $10.2 million (on average) for each facility that needs air pollution controls to comply with the standards, with an estimated nationwide annual cost of $61 million per year. The six affected facilities are owned by two parent companies (U.S. Steel and Cleveland-Cliffs, Inc.). Neither parent company qualifies as a small business, and the total costs associated with this final rule are expected to be less than 1 percent of annual sales revenue per ultimate owner.</P>
                    <P>
                        The EPA also modeled the economic impacts of the final rule using two standard partial equilibrium economic models: one for taconite iron ore pellets and one for steel mill products. The EPA linked these two partial equilibrium models by specifying interactions between supply and demand in both markets and solving for changes in prices and quantity across both markets simultaneously. These models use baseline economic data from 2019 to project the impact of the final rule on the market for taconite iron ore pellets and steel mill products. The models allow the EPA to project facility- and market-level price and quantity changes for taconite iron ore pellets and market-level price and quantity changes for steel mill products, including changes in imports and exports in both markets. The models project a 0.28 percent fall in the quantity of domestically produced taconite iron ore pellets along with a 0.63 percent increase in their price. The models also project a 0.02 percent fall in the quantity of domestically produced steel mill products along with an 0.01 percent increase in their price.

Overall, we found that in the population living in close proximity (within 10 kilometers (km)) of facilities, the following demographic groups were above the national average: White, Native American, and people living below the poverty level. The EPA defines EJ as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.”

                        For the Taconite Iron Ore Processing source category, the EPA examined the potential for EJ concerns by conducting a proximity demographic analysis for the eight existing taconite iron ore processing plants (seven operating plants and one indefinitely idled). The proximity demographic analysis is an assessment of individual demographic groups in the total population living within 10 km and 50 km of the facilities. The EPA compared the data from this analysis to the national average for each of the demographic groups. Since the taconite iron ore processing facilities are very large, a radius of 10 km was used as the near facility distance for the proximity analysis. A distance closer than 10 km does not yield adequate population size for the results. A summary of the proximity demographic assessment was included in Table 5 in the proposal for this rulemaking (88 FR 30931; May 15, 2023). The results show that for the population living within 10

                        km of the eight facilities, the following demographic groups were above the national average: White (93 percent versus 60 percent nationally), Native American (0.8 percent versus 0.7 percent nationally), and people living below the poverty level (15 percent versus 13 percent nationally). For two facilities (the UTAC and Minntac facilities), the percentage of the population living within 10 km that is Native American (1.9 percent and 2.3 percent) was more than double the national average (0.7 percent). For four facilities (Keetac, Hibbing, Minorca, and Minntac) the percentage of the population living within 10 km that is low-income is above the national average.

                    <P>This action sets new standards for Hg and revised standards for HCl and HF that will reduce the annual emissions of these HAP from taconite facilities. The Hg standards will reduce the health, environmental and cultural impacts of Hg identified by tribes in their comments by requiring the five taconite facilities (UTAC, Keetac, Hibbing, Minorca, and Minntac) that have nearby Native American populations and low-income populations above the national averages to reduce Hg emissions by up to 247 pounds per year (0.12 tpy). The emission limits must be met at all times (including periods of startup, shutdown, and malfunctions) and compliance must be demonstrated through monitoring of control device operating parameters and either periodic testing or CEMS.</P>

                    <P>This action involves technical standards. Therefore, the EPA conducted searches for the Taconite Iron Ore Processing NESHAP through the Enhanced National Standards Systems Network (NSSN) Database managed by the American National Standards Institute (ANSI). We also conducted a review of VCS organizations and accessed and searched their databases. We conducted searches for EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 4, 5, 5D, 17, 26A, 29 and 30B. During the VCS search, if the title or abstract (if provided) of the VCS described technical sampling and analytical procedures that are similar to the EPA's reference method, the EPA ordered a copy of the standard and reviewed it as a potential equivalent method. We reviewed all potential standards to determine the practicality of the VCS for this rule. This review requires significant method validation data that meet the requirements of EPA Method 301 for accepting alternative methods or scientific, engineering, and policy equivalence to procedures in the EPA referenced methods. The EPA may reconsider determinations of impracticality when additional information is available for any particular VCS.</P>
                    <P>No VCS were identified for EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 4, 5, 5D, 17 or 26A. One VCS was identified as an acceptable alternative to EPA Methods 3B, 29 and 30B.</P>
                    <P>
                        The EPA is allowing use of the VCS ASTM D6784-16, “Standard Test Method for Elemental, Oxidized, Particle-Bound and Total Mercury in Flue Gas Generated from Coal-Fired Stationary Sources (Ontario Hydro Method)” as an acceptable alternative to EPA Method 29 (Hg portion only) as a method for measuring Hg concentrations ranging from approximately 0.5 to 100 micrograms per normal cubic meter (µg/Nm
                        <SU>3</SU>
                        ). This test method describes equipment and procedures for obtaining samples from effluent ducts and stacks, equipment and procedures for laboratory analysis, and procedures for calculating results. VCS ASTM D6784-16 allows for additional flexibility in the sampling and analytical procedures from the earlier version of the same standard VCS ASTM D6784-02 (Reapproved 2008). VCS ASTM D6784-16 allows for the use of either an EPA Method 17 sampling configuration with a fixed (single) point where the flue gas is not stratified, or an EPA Method 5 sampling configuration with a multi-point traverse. For this action, only the EPA Method 5 sampling configuration with a multi-point traverse can be used. This method is available at ASTM International, 100 Barr Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959. See 
                        <E T="03">https://www.astm.org</E>
                        /. The standard is available to everyone at a cost determined by ASTM ($82). The cost of obtaining this method is not a significant financial burden, making the method reasonably available. Additional detailed information on the VCS search and determination can be found in the memorandum,

                         which is available in the docket for this action. The EPA solicited comment on potentially applicable VCS in the proposal for this rule. However, no other VCS were identified. The EPA is finalizing as proposed incorporating by reference the VCS ASTM D6784-16, “Standard Test Method for Elemental, Oxidized, Particle-Bound and Total Mercury in Flue Gas Generated from Coal-Fired Stationary Sources (Ontario Hydro Method),” as an acceptable alternative to EPA Method 29 (Hg portion only).

                    <P>
                        The EPA believes that the human health or environmental conditions that exist prior to this action result in or have the potential to result in disproportionate and adverse human health or environmental effects on communities with EJ concerns. The assessment of populations in close proximity of taconite iron ore processing plants shows Native American and low-income populations are higher than the national average (see section IV.E of this preamble). The higher percentages of Native American populations are near the UTAC and Minntac facilities. The higher percentages of low-income populations are near the Keetac, Hibbing, Minorca, and Minntac facilities. The EPA believes that this action is likely to reduce existing disproportionate and adverse effects on low-income populations and/or indigenous peoples. The EPA is finalizing new MACT standards for Hg and revised standards for HCl and HF. The EPA expects that at least five facilities would have to implement control measures to reduce Hg emissions to comply with the new Hg MACT standard (including the UTAC, Keetac, Hibbing, Minorca and Minntac facilities) and one facility would need to implement control measures to reduce HCl emissions to comply with the revised standard for HCl (the Tilden facility).

                    <HD SOURCE="HD2">I. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks</HD>
                    <P>Executive Order 13045 (62 FR 19885; April 23, 1997) directs Federal agencies to include an evaluation of the health and safety effects of the planned regulation on children in Federal health and safety standards and explain why the regulation is preferable to potentially effective and reasonably feasible alternatives. This action is not subject to Executive Order 13045 because it is not significant as defined in Executive Order 12866(3)(f)(1), and because the EPA does not believe the environmental health or safety risks addressed by this action present a disproportionate risk to children. In 2020, the EPA conducted a residual risk assessment and determined that risk from the Taconite Iron Ore Processing source category was acceptable, and the standards provided an ample margin of safety to protect public health (see 85 FR 45476 and Docket ID No. EPA-HQ-OAR-2017-0664-0163). For this rulemaking, we updated that risk analysis using new emissions data that the EPA received for some HAP emissions sources at the taconite facilities. We determined that these new HAP emissions estimates would not significantly change our previous estimates of the human health risk posed by the Taconite Iron Ore Processing source category. In this action the EPA is promulgating new emission standards for one previously unregulated pollutant (Hg) and revised emissions standards for two currently regulated pollutants (HCl and HF). These emissions standards will reduce Hg, HCl and HF emissions and thereby reduce children's exposure to these harmful HAP. We estimate that the installation of controls will reduce HCl and HF emissions by 683 tpy and 36 tpy, respectively, and will reduce Hg emissions by up to 247 pounds per year (0.12 tpy).</P>
                    <P>This action's health and risk assessments are protective of the most vulnerable populations, including children, due to how we determine exposure and through the health benchmarks that we use. Specifically, the risk assessments we perform assume a lifetime of exposure, in which populations are conservatively presumed to be exposed to airborne concentrations at their residence continuously, 24 hours per day for a 70-year lifetime, including childhood. With regards to children's potentially greater susceptibility to noncancer toxicants, the assessments rely on the EPA's (or comparable) hazard identification and dose-response values that have been developed to be protective for all subgroups of the general population, including children. For more information on the risk assessment methods, see the risk report for the July 28, 2020, final Taconite residual risk and technology review (RTR) rule (85 FR 45476), which is available in the docket. Therefore, the rulemaking finalizes actions that will result in health benefits to children by reducing the level of HAP emissions emitted from taconite iron ore processing plants.</P>

                            <P>(d) For each indurating furnace subject to the initial performance testing under § 63.9620(k)(1) or (l), you must determine compliance with the applicable emission limits for mercury, hydrogen chloride and hydrogen fluoride in tables 2 and 3 to this subpart by following the test methods and procedures in paragraphs (d)(1) through (9) of this section. You are not required to complete the initial performance test for mercury emissions when you are using a CEMS in accordance with paragraph (e) of this section.</P>
                            <P>(1) The furnace must be operated at or above 90 percent of capacity throughout the duration of the performance testing. If testing cannot be performed at or above 90 percent of capacity, you must provide an explanation for the lower production rate in your performance test plan. The lower production rate must be approved by the Administrator prior to beginning performance testing. For indurating furnaces that comply with the mercury emissions limit in table 2 to this subpart by adjusting the activated carbon injection rate based on the taconite pellet production rate, you must complete the performance testing for mercury in accordance with the provisions in § 63.9634(n).</P>
                            <P>(2) Use the methods specified in paragraphs (c)(1)(i) through (iv) of this section to select sampling port locations and the number of traverse points and to determine the volumetric flow rate, dry molecular weight, and moisture content of the stack gas.</P>
                            <P>(3) Determine the concentration of mercury for each stack using Method 29 or Method 30B in 40 CFR part 60, appendix A, or the voluntary consensus standard ASTM D6784-16 (incorporated by reference, see § 63.14). For Method 29 and ASTM D6784-16, the sample volume must be at least 1.7 dry standard cubic meters (dscm) (60 dry standard cubic feet) per run. For Method 30B, each test run must be at least one hour in duration.</P>
                            <P>(4) Determine the concentration of hydrogen chloride and hydrogen fluoride for each stack using Method 26A in 40 CFR part 60, appendix A. Each test must consist of three separate runs. The minimum sample volume must be at least 2 dscm per run.</P>
                            <P>(5) During each stack test run, determine the weight of taconite pellets produced and calculate the emissions rate of each pollutant in pounds of pollutant per long ton (lb/LT) of pellets produced for each test run. The weight of taconite pellets produced must be determined by measurement using weigh hoppers, belt weigh feeders, or weighed quantities in shipments, or calculated using the bulk density and volume measurements. If any measurement result for any pollutant is reported as below the method detection limit, use the method detection limit as the measured emissions level for that pollutant when calculating the emission rate. If the furnace has more than one stack, calculate the total emissions rate for each test run by summing the emissions across all stacks, as shown in Equation 4.</P>

                                 Beginning on January 25, 2021, submit all subsequent compliance reports to the EPA via CEDRI, which can be accessed through the EPA's Central Data Exchange (CDX) (
                                <E T="03">https://cdx.epa.gov/</E>
                                ). The EPA will make all the information submitted through CEDRI available to the public without further notice to you. Do not use CEDRI to submit information you claim as confidential business information (CBI). Anything submitted using CEDRI cannot later be claimed to be CBI. You must use the appropriate electronic report template on the CEDRI website (
                                <E T="03">https://www.epa.gov/electronic-reporting-air-emissions/compliance-and-emissions-data-reporting-interface-cedri</E>
                                ) for this subpart. The report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted. Although we do not expect persons to assert a claim of CBI, if persons wish to assert a CBI claim, submit a complete report, including information claimed to be CBI, to the EPA. The report must be generated using the appropriate form on the CEDRI website. Clearly mark the part or all of the information that you claim to be CBI. Information not marked as CBI may be authorized for public release without prior notice. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. Submit the file following the procedures in paragraph (c)(1) or (2) of this section. The same file with the CBI omitted must be submitted to the EPA via the EPA's CDX as described earlier in this paragraph (c). All CBI claims must be asserted at the time of submission. Furthermore, under CAA section 114(c) emissions data is not entitled to confidential treatment, and EPA is required to make emissions data available to the public. Thus, emissions data will not be protected as CBI and will be made publicly available. On or before January 25, 2021, for affected sources that commenced construction or reconstruction on or before September 25, 2019, if you had a startup, shutdown, or malfunction during the reporting period that is not consistent with your startup, shutdown, and malfunction plan you must submit an immediate startup, shutdown and malfunction report according to the requirements in § 63.10(d)(5)(ii). After January 25, 2021, for affected sources that commenced construction or reconstruction on or before September 25, 2019, and after July 28, 2020, or upon start-up, which ever date is later, for affected sources that commenced construction or reconstruction after September 25, 2019, an immediate startup, shutdown, and malfunction report is not required.
