                <P>The NRC is issuing a revision in the NRC's “Regulatory Guide” series. This series was developed to describe methods that are acceptable to the NRC staff for implementing specific parts of the agency's regulations, to explain techniques that the staff uses in evaluating specific issues or postulated events, and to describe information that the staff needs in its review of applications for permits and licenses.</P>
                <P>Proposed Revision 1 to RG 5.87, “Suspicious Activity Reports Under 10 CFR part 73,” was issued with a temporary identification of Draft Regulatory Guide, (DG)-5082 (ADAMS Accession No. ML23198A151).</P>
                <P>
                    This revision of the guide (Revision 1) provides additional guidance on suspicious activity reporting. These new and updated requirements are part of the NRC's final rule, titled “Enhanced Weapons, Firearms Background Checks, and Security Event Notifications” (hereafter the Enhanced Weapons rule), that was published in the 
                    <E T="04">Federal Register</E>
                     on March 14, 2023 (88 FR 15864). These provisions are found in the NRC's regulations under section 73.1215 of title 10 of the 
                    <E T="03">Code of Federal Regulations</E>
                     (10 CFR). Revision 1 to RG 5.87 provides acceptable methods that eligible applicants and licensees (collectively referred to as licensees in this RG) may use for reporting suspicious activity under NRC regulations. These provisions are found in the NRC's regulations under section 10 CFR 73.1215. Revision 1 to RG 5.87 provides guidance to applicants and licensees regarding an acceptable approach for reporting suspicious activity to local law enforcement agencies, the Federal Bureau of Investigation, the NRC, and the Federal Aviation Administration. Revision 1 to RG 5.87 also includes examples, considerations, and guidance to assist licensees in understanding their responsibilities in implementing 10 CFR 73.1215 requirements.

                     The final rule addresses barriers to sustainable housing opportunities for underserved communities by codifying existing FHFA practices in regulation and adding new requirements. Collectively, the actions in the final rule will improve FHFA's fulfillment of its statutory purposes and its oversight of the regulated entities and their fulfillment of their statutory purposes.

                    The final rule codifies in regulation much of FHFA's existing practices and programs regarding fair housing and fair lending oversight of its regulated entities, the Equitable Housing Finance Plan program for the Enterprises, and requirements for the Enterprises to collect and report language preference, homeownership education, and housing counseling information. The final rule makes changes to the Equitable Housing Finance Plan program to promote greater accountability for the Enterprises and public transparency, adds oversight of unfair or deceptive acts or practices to FHFA's fair housing and fair lending oversight programs, requires additional certification of compliance by the regulated entities, and establishes more precise standards related to fair housing, fair lending, and principles of equitable housing for regulated entity boards of directors (boards). The final rule also establishes a requirement for the Banks 
                    <PRTPAGE P="42769"/>
                    to report annually on any actions they voluntarily take to address barriers to sustainable housing opportunity for underserved communities in order to provide public transparency but does not require the Banks to undertake such actions or engage in the planning process required of the Enterprises.

FHFA issued a Report based on its comprehensive review in November 2023, “The Federal Home Loan Bank System at 100: Focusing on

The Report also noted that participants in FHFA's comprehensive review of the System suggested that FHFA consider requiring the Banks to prepare an affordable housing strategy or equitable housing finance plan that would describe their planned activities and summarize actions taken in the prior year.

                    <E T="03">Challenges Accessing Sustainable Housing Opportunities.</E>
                     There are many underserved communities experiencing significant challenges in accessing sustainable housing opportunities. This includes, for example, families living on tribal land, in rural areas, and in rental homes. Almost half of renters are cost-burdened, paying more than 30 percent of their income on housing, compared to only 22 percent of homeowners.
                    <SU>31</SU>
                    <FTREF/>
                     More than 10 million households headed by someone over age 65 are cost-burdened, with the median older renter having net worth under $6,000 in 2019.

                    <FTREF/>
                     By 2035, the population age 80 and over is expected to double from its level in 2016. The population in rural areas is older and more likely to have lower income levels, with the median income for renters in high needs rural areas being $26,422 compared to $40,505 nationally.
                    <SU>33</SU>
                    <FTREF/>
                     Lower incomes can lead to greater cost burdens in rural areas, particularly for renters. For example, in Middle Appalachia, 49 percent of renters are cost-burdened.

                     Individuals with disabilities also face housing challenges. As an increasing proportion of households wish to age in place, there is often a lack of housing opportunities that provide for mobility and other physical impairments. Two percent of total housing inventory is accessible for people with mobility disabilities, while 14 percent of Americans have mobility disabilities.

                     Additionally, LEP households, or those who are more comfortable transacting in a language other than English, may also experience barriers to housing opportunities and housing sustainability. Often, LEP borrowers will rely on their English-proficient child, who may not be familiar with mortgage lending terms, as a translator.

                    <FTREF/>
                     However, there have been persistent gaps in the homeownership rate by race and ethnicity. In the fourth quarter of 2023, the White homeownership rate was 73.8 percent, the Black homeownership rate was 45.9 percent, the Latino homeownership rate was 49.8 percent, and the Asian, Native Hawaiian and Pacific Islander homeownership rate was 63.0 percent.
                    <SU>43</SU>
                    <FTREF/>
                     The Black and White homeownership gap, at 27.9 percentage points as of the fourth quarter of 2023, has persisted over time, though there have been some modest reductions in the gap since 2019. Even when the racial homeownership rate is stratified by household income, there continue to be significant disparities in homeownership between racial groups, even in the highest income brackets. For example, for households with an income over $150,000, there exists a 10-percentage point gap between Black and White families.

                    A household's home is often its largest financial asset and key to wealth building and intergenerational wealth transfers, which in turn enable future generations to achieve homeownership. The Federal Reserve, in a 2022 survey, found that White families have the highest level of both median and mean family wealth: $285,000 and $1,367,170, respectively.

                     In contrast, Black families' median and mean wealth was $44,890 and $211,450, respectively. In other words, the typical Black family has about $16 in wealth for every $100 held by the typical White family. These wealth disparities grew between 2003 and 2018, though have narrowed slightly since 2018.

                     Black families are less likely to receive or expect to receive an inheritance, and, if they do, it is, on average, less than that of White households.

                     Black families are also less likely to obtain financial assistance from their personal networks, with 41 percent of Black families reporting they could receive $3,000 from family or friends compared to 72 percent of White families.

                     Moreover, many Black, Latino, and Asian households provide financial assistance to older generations, which slows their ability to save for a down payment.

For example, although Asians and Pacific Islanders as a whole have homeownership rates above 60 percent, Korean Americans' homeownership rate is 54 percent and

Similarly, when the Pacific Islander group is disaggregated, it becomes clear that Samoan and “Other Pacific Islander” applicants have significantly lower approval rates than Native Hawaiian and Chamorro applicants.

                    FHFA has released data on Fannie Mae's and Freddie Mac's automated underwriting systems, presenting gaps in approval rates for applicants from certain groups over time compared to other groups. These underwriting tools complete credit risk assessments on loan applicants to determine whether a loan is eligible for sale to the Enterprises. Although the move to a more automated, less subjective system to assess creditworthiness in mortgage market underwriting was an important step in eliminating bias in subjective underwriting decisions, further improvements in automated underwriting to reduce gaps would promote better access to sustainable housing opportunities. In the fourth quarter of 2023, White applicants' automated underwriting system applications had approval rates of about 83 percent and 89 percent for the automated underwriting systems of Fannie Mae and Freddie Mac, respectively; Black applicants had approval rates of about 65 percent and 73 percent; Latino applicants had approval rates of about 75 percent and 80 percent; Asian applicants had approval rates of about 86 percent and 90 percent; American Indian and Alaska Native applicants had approval rates of about 76 percent and 78 percent; and Native Hawaiian and Pacific Islander applicants had approval rates of about 77 percent and 82 percent.

                    Additional mortgage market disparities and challenges remain with respect to rural areas, manufactured housing, and other market segments. For example, rural areas suffer from a lack of affordable multifamily and single-family capital, and borrowers typically have lower credit scores and higher mortgage denial rates than the overall population of borrowers.

                     FHFA's Uniform Appraisal Dataset (UAD) Aggregate Statistics highlight that properties located in minority tracts have a higher proportion of appraised values less than the contract price. According to the 2021 appraisal statistics, 23.3 percent of homes in high minority tracts (80.1-100 percent) experienced an appraised value less than the contract price.
                    <SU>69</SU>
                    <FTREF/>
                     This is compared to 13.4 percent of homes in White tracts (0-50 percent) and 19.2 percent of homes in minority tracts (50.1-80 percent).

                    <FTREF/>
                     Additionally, FHFA identified examples of appraisal reports with direct references to the racial and ethnic composition of the neighborhood.
                    <SU>71</SU>
                    <FTREF/>
                     FHFA also identified time adjustments as a factor in appraisals that contributes to appraised values less than contract price, and racial disparities in appraisal outcomes.

                    <FTREF/>
                     Freddie Mac's research showed that properties in minority tracts are more likely than properties in White tracts to receive an appraisal lower than the contract price.

                     Similarly, the availability of appraisals for manufactured housing is limited due in part to the lack of comparable property data and the lack of familiarity with appraising techniques surrounding manufactured housing.

                </FTNT>
                <P>For the first Equitable Housing Finance Plan cycle, the Enterprises focused on addressing inequities and removing barriers to housing opportunities in a manner consistent with safety and soundness, and borrower sustainability for Black and Latino borrowers, as these borrower populations have been historically denied consistent and systemic fair, just, and impartial treatment and face persistent disparities in accessing housing. Although the Enterprises focused their 2022-2024 Equitable Housing Finance Plans on addressing barriers faced by Black and Latino borrowers, all implemented actions were beneficial to numerous underserved communities.</P>
                <P>
                    Freddie Mac pursued a variety of activities under its 2022-2024 Equitable Housing Finance Plan to achieve its objectives. To help eliminate disparities for Black and Latino communities in the Multifamily sector, Freddie Mac expanded financing for affordable housing developers and improved access to education and financing opportunities for diverse and emerging multifamily developers through its Develop the Developer program. Freddie Mac also established a fair servicing process to help identify gaps in loss mitigation outcomes, promoted Borrower Help Centers, and expanded use of its own renovation products to preserve affordable single-family homes. It financed rehabilitation loans to 
                    <PRTPAGE P="42774"/>
                    maintain and improve the quality of existing affordable housing stock and used its preservation loan agreements to preserve affordable rents at affordable housing properties that do not receive government subsidies. To promote renter empowerment at multifamily properties, Freddie Mac established a Renter Resource Organization program and expanded CreditSmart, a free financial and homeownership education curriculum for renters and borrowers.
                </P>
                <P>Freddie Mac employed affirmative outreach methods to ensure housing professionals were equipped with equity-related information, education, and resources to ensure its servicing and oversight policies promote positive borrower-home retention outcomes. Freddie Mac followed up with its Mission Servicing Oversight Framework that allows the Enterprise to work with servicers that provide high-touch engagement with at-risk borrowers to offer early delinquency counseling and help mitigate mortgage defaults. To combat appraisal bias, a text detection method was added to Freddie Mac's Loan Collateral Advisor tool to flag subjective words and phrases that could indicate bias to better educate appraisers and correct the use of potentially biased language in appraisal reports with real-time feedback. Finally, both Freddie Mac and Fannie Mae continued the Appraiser Diversity Initiative to provide scholarships and promote the diversity of new entrants to the residential appraisal profession by reducing the barriers to entry, including education, training, and experience requirements.</P>
                <P>Fannie Mae also pursued a variety of activities under its 2022-2024 Equitable Housing Finance Plan to achieve its objectives. Fannie Mae introduced HomeView, a free online homeownership education course designed to address misconceptions and knowledge gaps about the home purchase and mortgage qualification process. Fannie Mae also made the HomeView course available in Spanish. Fannie Mae used its Here2Help program to provide counseling services for renters and homeowners facing financial hardships and offered its Future Housing Leaders program to connect college students from diverse institutions to career opportunities in the housing industry. In its efforts to assist Black and Latino renters and support affordable housing in the Multifamily sector, Fannie Mae offered pricing and underwriting incentives for multifamily borrowers that set aside at minimum 20 percent of a property's units as affordable units for renters earning up to 120 percent of the area median income (AMI) in very low-income markets through their Sponsor-Dedicated Workforce and Sponsor-Initiated Affordability programs. Fannie Mae also introduced the Multifamily Positive Rental Payment History program to help renters establish and improve credit scores using bank transaction data and is currently exploring ways to decrease renters' upfront security deposits, which can then be saved as cash reserves and later used towards down payment and/or closing costs. Fannie Mae also agreed to partner with local housing organizations to support the revitalization and expansion of housing opportunities in historically Black neighborhoods.</P>
                <P>
                    In their efforts to advance equity as part of their Equitable Housing Finance Plans, both Enterprises provided liquidity for eligible lender-developed Special Purpose Credit Programs (SPCPs) and developed their own SPCPs to expand access to mortgage funding for historically underserved communities.

                <P>Fannie Mae initiated several appraisal modernization efforts, including appraisal text scanning reviews and introduction of the Value Acceptance/Property Data option that permits lenders to bypass an appraisal if interior and exterior property data collection is provided to verify the property's eligibility prior to the note date. In order to extend credit access to underserved communities that have a low credit score or no credit score established, Freddie Mac improved its automated underwriting system, Loan Product Advisor (LPA), to increase accuracy and fairness by removing reliance on third-party credit scores and using a proprietary, enhanced credit view that focuses specifically on mortgage credit risk. LPA was also improved to consider bank transaction data, allowing positive cash flow and on-time rent payments to be factored into loan purchase decisions. Fannie Mae also improved its automated underwriting system, Desktop Underwriter (DU), to consider a borrower's positive rent payment history as part of the credit risk assessment and allow for cash-flow assessments using a borrower's bank transaction data in cases when the borrower has no established credit score.</P>
                <P>The Enterprises' respective performance reports demonstrate their efforts to ensure all communities have greater access to sustainable rental and homeownership opportunities and better preparedness for obtaining a mortgage loan, all while fulfilling their statutory missions to promote affordable housing, serve the public interest, and ensure safety and soundness. Ultimately, FHFA expects that Enterprise changes implemented as part of the inaugural Equitable Housing Finance Plans will have long-standing impacts, even as the Enterprises proceed to devise new objectives to advance sustainable housing opportunities and address a new set of barriers impacting the spectrum of underserved communities for the 2025-2027 Equitable Housing Finance Plans.</P>
                <P>
                    Based on FHFA's experience in overseeing the activities undertaken by the Enterprises pursuant to their 2022-2024 Equitable Housing Finance Plans and the public reporting provided by the Enterprises, FHFA finds that the Enterprises' activities and the EHFP program have helped the Enterprises meet their statutory purposes under the authorizing statutes and helped FHFA fulfill its statutory duties. FHFA finds these activities have assisted the Enterprises in fulfilling their mission to provide stability to the secondary market for residential mortgages; provide ongoing assistance to the secondary market for residential mortgages (including activities related to mortgages on housing for low- and moderate-income families) by increasing the liquidity of mortgage investments and improving distribution of investment capital available for residential mortgage financing; and promote access to mortgage credit throughout the United States.

                <P>Industry commenters challenged codification of FHFA's oversight of the regulated entities' compliance with UDAP, arguing that UDAP is distinct from fair lending and fair housing, and exceeds congressional intent for FHFA's authority. Commenters also raised concerns that codification of UDAP compliance oversight may result in unintentional consequences for primary mortgage market lenders and asserted that codifying UDAP compliance in regulation was legally unnecessary. One commenter similarly contended that because the regulated entities do not interact with consumers in the same way as other lenders subject to UDAP, UDAP compliance requirements for the regulated entities were inappropriate.</P>
                <P>
                    FHFA considered these comments and determined that the proposed provisions are necessary to carry out its statutory duties and purposes and the benefits of codifying FHFA's oversight of regulated entity UDAP compliance in regulation otherwise outweigh commenters' concerns. The broad language of Section 5 of the FTC Act prohibits “unfair or deceptive acts or practices in or affecting commerce,” which would encompass activities of FHFA's regulated entities.

                    FHFA acknowledges that UDAP is distinct from fair lending and fair housing. In the proposed rule, FHFA distinguished between the two by separating UDAP specific language from fair lending specific language to clarify that FHFA does not view UDAP compliance and fair lending compliance as identical.

                    Codification of the Enterprises' and the Banks' existing UDAP compliance obligations would be consistent with the broad nature of Section 5 of the FTC Act, the actions of the prudential regulators for their regulated entities, and FHFA's supervisory responsibilities.
                    <SU>95</SU>
                    <FTREF/>
                     For example, such compliance would support FHFA's principal duty to ensure that the regulated entities manage risks and foster fair, efficient, and competitive housing finance markets. Indeed, one of the core purposes served by UDAP prohibitions is to correct actions that impede efficient and competitive marketplaces, such as those that “unreasonably create[ ] or take[ ] advantage of an obstacle to the free exercise of consumer decision-making.” 
                    <SU>96</SU>
                    <FTREF/>
                     Given the strong statutory support for fair lending oversight, FHFA's concurrent oversight of UDAPs in connection with fair lending oversight would further the efficient supervision and examination of the regulated entities. Ensuring UDAP compliance can also reasonably be understood to be part of FHFA's duty to ensure that the regulated entities' activities and operations are consistent with the “public interest.”

                    Furthermore, FHFA's regulated entities have significant impacts on consumers. The Enterprises maintain underwriting models and other automated systems and lending and servicing standards that have substantial potential to affect consumers and the housing market. There are certain circumstances involving mortgage servicing and disposition of Real Estate Owned (REO) properties where FHFA's regulated entities or their agents interact with consumers. The regulated entities also provide consumer education and outreach activities to borrowers and applicants. Additionally, UDAP is not limited to consumers

                     and the Enterprises and Banks have a duty to ensure that their dealings with other parties protected by UDAP standards are compliant and that their standards that affect primary market lenders are consistent with UDAP. FHFA plans to give due consideration to any effects on primary market participants in the supervision and regulation of regulated entity UDAP compliance, just as it does in all aspects of its work, and to coordinate with other regulators as appropriate. FHFA agrees that it is not necessary for FHFA to issue a rule to supervise the regulated entities for UDAP compliance.

                     However, given that FHFA had not previously supervised and enforced UDAP standards, FHFA believes that it was valuable to provide notice and opportunity for comment to both the regulated entities and the public. Accordingly, FHFA is adopting § 1293.11(b) of the final rule on regulated entity UDAP compliance with no changes from the proposed rule.

                <P>FHFA proposed to require the board of directors of a regulated entity to direct the entity's operations in conformity with fair lending, fair housing, and UDAP laws. FHFA received two comments from the Enterprises regarding the responsibilities of boards of directors. One comment raised concerns that requiring boards of directors to direct the operations of a regulated entity consistent with fair housing, fair lending, and UDAP authorities is duplicative of existing compliance duties and places fair lending above other compliance obligations.</P>

                    FHFA believes that the proposed language clarifies rather than duplicates existing compliance duties. The regulated entities are currently required to comply with fair housing, fair lending, and UDAP laws,

                     The proposed language clarified that the board of directors must consider fair lending, fair housing, and UDAP compliance in its oversight of the regulated entity. The proposed section referenced 12 CFR 1239.4(b)(4), which sets out the duties of the regulated entities' boards of directors. Section 1239.4(b)(4) states that each director on the board of a regulated entity has a duty to “[d]irect the operations of the regulated entity in conformity with the requirements set forth in the authorizing statutes, the Safety and Soundness Act, and this chapter[.]” The proposed language referenced the general board responsibilities laid out in § 1239.4(b)(4) and makes clear that that responsibility includes directing the regulated entity's behavior in compliance with fair lending, fair housing, and UDAP laws in addition to compliance with the Safety and Soundness Act and other authorizing statutes such as the Enterprises' charter acts, not in lieu of compliance with other authorities.

                    One commenter objected to the use of “directs” as the board of directors' responsibility, arguing that a board of directors actually “oversees” the operations of an entity. Section 1239.4(b)(4) uses the term “direct” in regard to the board of directors' oversight responsibility.

                    <FTREF/>
                     In the preamble of the final rule promulgating § 1239.4(b)(4), FHFA responded to a comment asking whether “directs” was the appropriate language for a board's responsibilities.
                    <SU>104</SU>
                    <FTREF/>
                     FHFA explained that the language had originated in regulations promulgated by FHFA's predecessor agencies, the Federal Housing Finance Board and the Office of Federal Housing Enterprise Oversight.
                    <SU>105</SU>
                    <FTREF/>
                     After analysis of state laws governing the Enterprises' corporate responsibility duties, FHFA revised the proposed language to read that management of the entity should be “by or under the direction of” of the board.
                    <SU>106</SU>
                    <FTREF/>
                     FHFA expects boards of directors to direct management consideration of whether and how much potential decisions heighten or mitigate fair lending, fair housing, and UDAP risk, as appropriate, prior to making decisions. After consideration, FHFA believes that the use of “direct” in the proposed rule is consistent with the language in § 1239.4(b)(4) of this chapter as it appropriately reflects a board's responsibilities and has retained it in this final rule.

                <P>Accordingly, FHFA is adopting § 1293.11 of the final rule with no changes from the proposed rule.</P>
                <HD SOURCE="HD2">D. Certification of Compliance</HD>
                <P>FHFA proposed to require the regulated entities to certify compliance with fair lending, fair housing, and UDAP laws with each regular report concerning fair housing and fair lending submitted. FHFA received five comments regarding the proposal to require certifications of compliance.</P>
                <P>Comments from the regulated entities uniformly opposed the proposed requirement for certifications of compliance with fair housing, fair lending, and UDAP laws, stating it would be too burdensome and could create liability. One commenter suggested that such a certification would place fair lending and fair housing above other compliance concerns. A second commenter suggested that such a certification would require “absolute compliance” and suggested instead that FHFA require a certification of accuracy or certification of a “system reasonably assured to ensure compliance.” A third commenter opposed the proposed requirement on the basis that it was too broad and recommended altering the language to certify compliance “to the best of one's knowledge and belief following reasonable or due inquiry of the certifying official.”</P>
                <P>One civil rights advocate commenter observed that FHFA has authority for requiring certifications and proposed expanding the language to apply to special reports and regular reports, and to cite Section 5 of the FTC Act directly. One industry commenter opposed requiring certification of compliance with UDAP, stating that inclusion of UDAP was inappropriate and could have unintended consequences for primary market participants. FHFA understood this comment to be more directly related to proposed § 1293.11(b) and responded to it in Section II.B. above.</P>
                <P>
                    FHFA does not intend to create liability with this certification, but instead to incentivize consideration of fair lending compliance throughout decision-making processes. FHFA's stated intention not to create liability is consistent with proposed § 1293.1(c), which further states that “[n]othing in this part creates a private right of action.” FHFA also believes that a requirement to certify compliance would be consistent with the Enterprises' own practices in certifications required of seller/servicers 
                    <SU>108</SU>
                    <FTREF/>
                     and HUD's practices in certifications required for grantees.
                    <SU>109</SU>
                    <FTREF/>
                     After consideration of the various alternatives proposed by the commenters, FHFA believes that qualifying the certification “to the best of the certifier's knowledge and belief following reasonable or due inquiry of the certifying official” adequately incentivizes compliance management efforts without creating an undue burden of certifying absolute compliance.

FHFA intends this revision to make clear that identification of a fair lending compliance risk following the completion of the certification does not on its own create liability for the regulated entity.

                <P>
                    FHFA proposed the designation of the Equitable Housing Finance Planning subpart (proposed subpart C) as a Prudential Management and Operations Standard (“PMOS” or “prudential standard”). While some commenters supported a PMOS designation, most commenters did not support it, and suggesting it was an inappropriate use of PMOS authority. As discussed in the proposed rule preamble, FHFA proposed the PMOS designation because the Enterprise equitable housing finance planning framework is consistent with the Enterprises' authorizing statute obligations and FHFA's statutory charges related to ensuring the regulated entities operate consistent with the public interest and that FHFA furthers fair housing in its oversight of the regulated entities.

                     The prudential standards regarding internal controls and information systems may be relevant if FHFA determines an Enterprise failed to monitor the overall effectiveness of its internal controls and key risks on an ongoing basis and ensure that business units and internal and external audit teams conduct periodic evaluations related to the equitable housing finance planning requirements.
                    <SU>116</SU>
                    <FTREF/>
                     The prudential standards for independence and adequacy of internal audit systems may also be relevant if FHFA determines an Enterprise failed to conduct risk-based audits related to equitable housing finance planning, or an Enterprise's internal audit department failed to determine whether violations, findings, weaknesses, and other issues reported by FHFA with regard to the equitable housing finance planning have been promptly addressed.

                     Lastly, the prudential standard for the board and senior management to ensure an Enterprise's risk profile is aligned with its mission objectives and the prudential standard related to overall risk management and compliance with laws, regulations and supervisory guidance may be relevant if FHFA determined an Enterprise's equitable housing finance planning efforts did not reflect adherence to the authorizing statutes, the Fair Housing Act, the Equal Credit Opportunity Act, the requirements of the final rule, and other relevant guidance and regulations, and posed reputational or other material risks to the Enterprise.

                     Although FHFA is not designating any part of the final rule as a new PMOS, an Enterprise's failure to properly engage in equitable housing finance planning could result in a determination that it has failed to meet one or more of the existing PMOS, and must take corrective action.

In addition to the existing PMOS discussed above which may be relevant to ensure compliance by the Enterprises, the final rule provides that FHFA may enforce compliance in any manner and through any means within its authority, including but not limited to adverse examination findings or through supervision or enforcement under 12 U.S.C. 4511(b), 4513b, 4631, or 4636.

                <P>
                    FHFA asked commenters on the proposed rule whether “equity” should 
                    <PRTPAGE P="42779"/>
                    be defined in the rule. Most commenters supported FHFA defining “equity” in the regulatory text to prevent confusion and ensure the Enterprises take actions that promote the Agency's definition of “equity.” Two commenters argued that imposing an “equity” definition and requirements on the regulated entities is outside FHFA's statutory mission.
                </P>
                <P>
                    FHFA recognizes that a definition of “equity” has been explicitly provided in HUD's most recent proposed Affirmatively Furthering Fair Housing (AFFH) rule,
                    <SU>119</SU>
                    <FTREF/>
                     which would require equity plans from HUD program participants and which FHFA reviewed in developing the proposed and final rules given that both equity plans are grounded in the statutory requirement to affirmatively further fair housing.
                    <SU>120</SU>
                    <FTREF/>
                     According to a 2021 Presidential Memorandum, the AFFH mandate “. . . is not only a mandate to refrain from discrimination but a mandate to take actions that undo historic patterns of segregation and other types of discrimination and that afford access to long-denied opportunities.”

                    <FTREF/>

                    The proposed rule did not specifically define “equity,” but did include defined terms that would form the basis of the rule's requirements, informed by the concept of equity as it has been interpreted under the Fair Housing Act's affirmatively furthering statutory provision, the proposed AFFH rule, Presidential Memoranda, and Executive Orders noted above, as well as incorporating concepts to ensure consistency with FHFA's public interest duty and the Enterprises' Charter Act obligation to promote access to mortgage credit throughout the Nation. The proposed rule provides a concrete framework through which the Enterprises may work to promote sustainable housing opportunities for all homebuyers, homeowners, and tenants by taking meaningful actions under an “equitable housing finance plan” to overcome “barriers” faced by “underserved communities” throughout the country.
                    <SU>123</SU>
                    <FTREF/>
                     For example, the proposed rule's “underserved community” definition includes groups with a shared characteristic or geographic area that previously had or currently have difficulty accessing housing opportunities compared with groups of people without the shared characteristic or other areas.
                    <SU>124</SU>
                    <FTREF/>
                     The proposed rule defined “barrier” to refer to Enterprise actions, products, or policies, or aspects of the housing market that can reasonably be influenced by the Enterprise's actions, products, or policies, that contribute to inequitable housing opportunities and outcomes for underserved communities.

                    <FTREF/>
                     The “equitable housing finance plan” requires an Enterprise to identify barriers to sustainable housing opportunities faced by one or more underserved communities, and subsequently, establish objectives that demonstrate a focus to combat those identified barriers through the EHFP plan and the outcomes sought.

                </FTNT>
                <P>FHFA believes the Equitable Housing Finance Planning program standards and provided definitions of “underserved community,” “barrier,” and “equitable housing finance plan” provide a clear framework for the Enterprises' work to advance the availability of mortgage credit and housing for all individuals. FHFA believes it is important to recognize there are many underserved communities throughout the nation, and it is important to understand each community's unique barriers, starting points, and access to opportunities that have been shaped by history and the present day. FHFA believes the proposed rule's approach provides a flexible and adaptable framework for addressing the needs of underserved communities that exist today, or that may arise in the future. Accordingly, consistent with the proposed rule, the final rule does not include a definition of “equity.” FHFA may consider issuing additional guidance or engaging in future rulemaking on this topic based on additional experience with the program and engagement with stakeholders.</P>
                <HD SOURCE="HD2">H. Resource Disclosures</HD>
                <P>FHFA proposed a requirement in § 1293.23(b)(4) for the Enterprises to submit disclosures of resources dedicated to the Equitable Housing Finance Plans as part of their performance reports. Commenters who specifically addressed this issue opposed the proposed requirement. Some commenters expressed concerns about reputational risks, due to the high potential for subjectivity when different parties examine the same value. For example, consumer advocates may posit that the Enterprises' financial expenditures for meaningful actions are inadequate, while industry commenters may view the same value as an excessive and unnecessary expenditure. Other commenters suggested a financial disclosure requirement would be burdensome for the Enterprises and difficult to calculate accurately, as “resources” could be interpreted to include anything from closing cost credits to administrative costs.</P>
                <P>Based on the comments, FHFA considered the requirement in the proposed rule as well as an alternative limited resource disclosure requirement and removing the requirement. The limited disclosure requirement would mandate the Enterprises to publish a summary of cost savings and benefits delivered to consumers for homeownership programs or products created pursuant to an Equitable Housing Finance Plan to support Enterprise accountability and transparency. However, concerns of subjectivity when interpreting any financial disclosures and whether financial disclosures are sufficient or excessive would still remain. Further, it could be difficult for the Enterprises to determine what monetary threshold constitutes sufficient resource dedication, and what constitutes a resource for Plan purposes, as some resources are not easily quantifiable or may be issued by a third party because of Enterprise efforts. Accordingly, for these reasons, FHFA has not included this alternative more limited financial disclosure requirement in the final rule.</P>
                <P>
                    FHFA finds the comments on the proposed financial disclosures requirement persuasive and has 
                    <PRTPAGE P="42780"/>
                    determined not to include that requirement in the final rule at this time. FHFA agrees with commenters that it can be difficult to fully and uniformly account for resource expenditures. In contrast to federal grant-making, the Enterprises provide support to underserved communities through the Equitable Housing Finance Plans through a variety of mechanisms. These mechanisms include both direct spending and indirect support, including but not limited to closing cost credits, special pricing, and policy enhancements. The Enterprises' indirect support can be difficult to quantify and compare across projects. Further, “typical” or customary costs may differ significantly across markets, resulting in aggregated data that does not provide meaningful insights and transparency. For these reasons, FHFA does not believe at this time that the potential burdens of the proposed rule provision or the alternative more limited disclosure requirement discussed above would be outweighed by the usefulness of information provided.
                </P>
                <P>
                    FHFA recognizes that although financial disclosures are one way to monitor program effectiveness and prioritization of housing equity, other performance metrics may better illustrate the impact of the Plans, including accept rate gaps, home loan acquisitions, and other performance metrics that are included in the Enterprises' performance reports.
                    <SU>127</SU>
                    <FTREF/>
                     Enterprise accountability can also be achieved through FHFA's Enterprise Fair Lending and Fair Housing Rating System (Rating System).
                    <SU>128</SU>

                     This Rating System will directly evaluate Enterprise impact, performance, public engagement, and overall commitment to addressing barriers to sustainable housing opportunities for underserved communities as part of FHFA's confidential supervisory ratings. Additionally, as discussed below, FHFA is also adopting a requirement in § 1293.27 of the final rule for a public narrative assessment of the Plans that will also contribute to Enterprise accountability and public transparency. FHFA may consider implementing a financial disclosure requirement in the future based on additional experience with the program and engagement with stakeholders.

                <HD SOURCE="HD2">I. Public Engagement</HD>
                <P>Proposed § 1293.24 included an annual public engagement requirement for FHFA, and a requirement for the Enterprises to consult with the public, including members of underserved communities and housing market participants, in the development and implementation of their Equitable Housing Finance Plans and updates, and describe such consultation in their Plans. The Enterprises' comments on the proposal requested additional instructions and flexibility for public engagement and input. Some other commenters were concerned that the absence of detailed public engagement requirements in the proposed rule could lead to inadequate public outreach and requested more rigorous requirements. One commenter recommended mandating the Enterprises provide several opportunities for input during the year via public meetings in each of the nine census divisions.</P>
                <P>Although FHFA agrees that the Enterprises should provide ongoing opportunities for public engagement, FHFA does not believe the rule should state specific requirements for the Enterprises' public engagement because it may cause the Enterprises to limit public engagement efforts only to those specified in the rule and may otherwise inhibit flexibility in how public engagement is achieved. FHFA also believes mandating Enterprise engagement by census division is inappropriate at this time, as the census divisions are not prominently known to the public and may be unduly burdensome for the Enterprises, due to the additional resources necessary to employ multiple meetings in the various census divisions across the country, and subsequently, incorporate the public input in their EHFP reports each year before the September 30 due date.</P>
                <P>Making this provision too prescriptive could have the unintended consequence of hindering an Enterprise's innovative and flexible ways of engaging with the public. Due to the specifics of the final rule, the underserved communities and barriers addressed with meaningful actions will continuously change, and the program standards must be flexible enough to allow for that. FHFA expects that the Enterprises would seek feedback from stakeholder groups about how best to design their Plans. Affording flexibility regarding public engagement will allow for more focused and targeted Plans based on specific Enterprise public outreach efforts, which must be described in the Plan as part of the public engagement requirement. Accordingly, FHFA has not implemented any changes to the public engagement requirements in this final rule. FHFA may provide further guidance on the adequacy of public engagement in the future based on additional experience with the program and engagement with stakeholders.</P>

                <P>FHFA asked commenters on the proposed rule whether an evaluation of the Enterprises' equitable housing performance should be publicly issued, or whether evaluation metrics should be included in the Enterprises' public performance reports. Commenters generally supported FHFA publishing an evaluative narrative to facilitate constructive public input and increase Enterprise transparency and accountability. Two commenters suggested the Enterprises should granularly disclose the success or failure of reports, and provide full reporting on all Enterprise pilot programs at the local level.</P>

                    FHFA's Rating System assesses the Enterprises' compliance with fair lending and fair housing standards and their planning and execution with respect to Equitable Housing Finance Plans.

                     One of the four rating components is equitable housing finance, which measures the performance of each Enterprise under its Equitable Housing Finance Plan activities. The Rating System complements other existing FHFA supervisory rating systems used by FHFA's Division of Bank Regulation, Division of Enterprise Regulation, and Office of Minority and Women Inclusion.

                     Supervisory ratings are generally confidential supervisory information and have not historically been publicly disclosed in order to encourage greater candor, cooperation, and compliance by the regulated entity. One exception to this general policy in financial regulation is the disclosure of Community Reinvestment Act (CRA) ratings.

                    As part of evaluating comments on this issue, FHFA considered disclosing the supervisory ratings, disclosing a narrative assessment of the equitable housing finance component, and 
                    <PRTPAGE P="42781"/>
                    developing separate public evaluation metrics. FHFA believes that maintaining the confidential supervisory nature of the ratings under the Rating System, including the equitable housing finance component, is most consistent with agency policy of maintaining confidentiality of supervisory information. While FHFA considered public evaluation metrics similar to those provided under the Duty to Serve program,
                    <SU>133</SU>
                    <FTREF/>
                     FHFA believes that implementation of two separate evaluation systems—one internal to FHFA and one public-facing—to assess the equitable housing finance program metrics would likely create implementation challenges for FHFA and the Enterprises. However, FHFA does agree with the commenters that favored some form of public evaluation and has added a provision in § 1293.27 of the final rule requiring FHFA to publish a narrative evaluative assessment of each Enterprise's program performance. FHFA believes this change will foster greater public transparency and Enterprise accountability, while reducing the burden associated with developing separate public evaluation metrics. This provision requires FHFA, by May 15 of each year, to publish on its website a narrative assessment evaluating each Enterprise's performance under its respective Equitable Housing Finance Plans. This requirement will also provide greater alignment of the Equitable Housing Finance Program with the CRA, though FHFA acknowledges the CRA examinations ratings disclosures are more extensive.

                    FHFA asked commenters on the proposed rule whether the Banks should be required to comply with the same Equitable Housing Finance Planning requirements as the Enterprises, including submission of Equitable Housing Finance Plans. Some commenters suggested that imposing such requirements on the Banks would be too burdensome and unnecessary, stating that the Banks' Affordable Housing Programs and Community Investment Programs already address the needs of underserved communities.

                     Several other commenters requested that FHFA ensure the Banks do more to promote fair and affordable housing by determining appropriate mechanisms and structures to assess the Banks' equity efforts. The regulated entities' comments emphasized the differences between the Enterprises and the Banks, including contrasts in acquisition volume, market share, and the Banks' issuance of advances to their members.

                <P>FHFA believes addressing barriers to sustainable housing opportunities for underserved communities should be a priority for all its regulated entities and, after considering comments requesting appropriate mechanisms for the Banks, FHFA is adopting a requirement in the final rule for the Banks to report any voluntary meaningful actions taken to further equity in the past year. FHFA expects to engage in future guidance and rulemaking specific to the Banks, in response to and consistent with “The Federal Home Loan Bank System at 100: Focusing on the Future” Report. Although FHFA recognizes the Banks' activities have less influence on aspects of the housing market in comparison to the Enterprises' activities, FHFA believes addressing barriers to sustainable housing opportunities should be a priority for all regulated entities and is consistent with the public interest and acknowledges commenters' requests for FHFA to develop appropriate mechanisms for the Banks. FHFA recognizes that equitable housing finance planning requires time, effort, and financial and administrative resources from the Enterprises, which may not be feasible for the Banks to provide at the same level, considering the difference in their resources. Therefore, consistent with the proposed rule, the final rule does not adopt the equitable housing finance planning requirements for the Banks, but requires instead the reporting of voluntary meaningful Bank efforts for addressing barriers to sustainable housing opportunities in new subpart D.</P>
                <P>This addition recognizes the importance of equitable housing finance planning for all regulated entities, while also recognizing the differences between the Banks and the Enterprises and providing FHFA and stakeholders additional time and information to further refine any potential future requirements for the Banks. FHFA has determined that a delayed effective date for this subpart is appropriate, considering the differences between the Banks and the Enterprises and that the Enterprises are conforming to similar requirements already. Subpart D will be effective on February 15, 2026.</P>

An Enterprise requested clarification of the proposed housing counseling data collection requirement. Commenters on the proposed rule generally supported codifying the data collection requirements for collecting language preference and data regarding completion of housing counseling and homeownership courses, though some commenters did not support the requirement. Some commenters provided suggestions for future policies that would support limited English proficient (LEP) communities. Additionally, the proposed requirement is substantially the same as the policy announced by FHFA in May 2022 mandating lender use of the Supplemental Consumer Information Form (SCIF) as part of the application process for loans that will be sold to the Enterprises.

                <P>
                    As noted above, an Enterprise requested clarification of the proposed housing counseling data collection requirement. At this time, the Enterprises' SCIF instructions require lenders to provide an opportunity for the borrower to indicate a language preference or that they would prefer not to respond.

                    education was not required by a loan program, and analysis of current data indicates that voluntary data is being provided in some circumstances.

                     FHFA did not intend to change the existing policy or instructions as part of the proposed rule, which was intended to codify the existing policy and practice. FHFA believes that the instructions and current practice comply with the proposed and final rule text. FHFA appreciates the comments provided on future LEP policy, but based on the scope of the final rule, is not addressing them in the final rule.

FHFA does not believe this is a reasonable interpretation of the statute. Applying the commenters' reading to the section 4565 as a whole makes clear that it is not a reasonable reading, as there are numerous categories which are joined by “and” which are mutually exclusive or clear from the context that they are not intended to be joined requirements which must all be satisfied simultaneously by individual actions. Regardless, the final rule does not rest solely on this provision.

                     Some commenters asserted that fair housing and fair lending with respect to the Enterprises are solely HUD's responsibility, because 12 U.S.C. 4545 directs the Secretary of HUD to take certain actions related to fair housing and the Enterprises.

                     This provision does not mean that FHFA is not responsible for overseeing fair housing and fair lending compliance at the Enterprises.

                     Some commenters asserted that the rule would be illegal under the Equal Protection Clause. FHFA disagrees. The final rule sets forth a strategic planning, public input, and public reporting process for addressing the needs of underserved communities, which will necessarily vary over time. The term “underserved community” is defined broadly to encompass many different types of communities, including communities that do not share any particular race or ethnicity, and the rule does not impose any requirement to take actions that are racially restricted. Further, the Plans merely provide public transparency into the Enterprise's analyses, the barriers experienced by that underserved community, and actions the Enterprises intends to take to attempt to overcome those barriers. Any such actions are subject to fair lending and fair housing laws, including the Equal Credit Opportunity Act and the Fair Housing Act, which generally prohibit discrimination based on prohibited characteristics with limited exceptions (which include special purpose credit programs). This final rule specifies that unlawful actions are not permitted in several provisions, including §§ 1293.1(b), 1293.11(a), (b), 1293.12(b), 1293.22(f)(2), (g), 1293.23(d)(2), and 1293.32(d)(2). Current Equitable Housing Finance Plan reports demonstrate that actions taken under the current Plans, which identify Black and Latino communities as underserved communities, benefit applicants, borrowers, and renters of all races.

                     FHFA disagrees. The final rule is not a sweeping change either with respect to oversight of the regulated entities or with respect to the equitable housing finance plan program. Much of the content of the final rule codifies existing policy. Further, the final rule is consistent with FHFA's core statutory purposes as discussed above. With respect to equitable housing finance as well as other aspects, the final rule does not impose changes of vast economic or political significance. It requires a strategic planning process supported by broad stakeholder input and program standards to more effectively achieve FHFA's and the Enterprises' public mission, in concert with other FHFA programs and requirements. It also includes guardrails and processes for self-correction to ensure activities remain consistent with the law and the Enterprises' Congressionally chartered purposes and that FHFA's oversight remains within the bounds of the law and the Constitution.

                <HD SOURCE="HD2">A. Section 1293.1(d), Severability Clause</HD>
                <P>FHFA has added a severability clause in § 1293.1(d) of the final rule. FHFA believes that it is appropriate to make clear its intention in the final rule that all provisions of the final rule be severable given that the final rule contains many thematically related but ultimately independent regulatory requirements, each of which FHFA believes is independently important to pursue through rulemaking and can function independently.</P>
                <HD SOURCE="HD2">B. Section 1293.12(a), Reports, Data, and Certification</HD>
                <P>FHFA has added a reference to § 1293.11(b) in § 1293.12(a) of the final rule to make clear that reports to FHFA may be required to include matters related to UDAP compliance, consistent with the certification attached to the report required in § 1293.12(b). FHFA has also changed the title of subpart B to include UDAP.</P>
                <HD SOURCE="HD2">C. Section 1293.12, Certification of Compliance</HD>
                <P>FHFA has revised § 1293.12(b) in the final rule by qualifying the required certification of compliance with fair lending, fair housing, and UDAP laws “to the best of the certifier's knowledge and belief following reasonable or due inquiry of the certifying official.” FHFA determined that certifying compliance to the best of the certifier's knowledge and belief will adequately incentivize identification of risk without imposing additional liability for certifying to absolute compliance.</P>
                <HD SOURCE="HD2">D. Section 1293.21, General</HD>
                <P>FHFA has not included in the final rule the proposed rule provision that would have identified Enterprise Equitable Housing Finance Planning as a prudential standard by regulation pursuant to section 4513(b) of the Safety and Soundness Act. Accordingly, the title of § 1293.21 has changed to remove “Identification of subpart as a prudential standard,” and now states “General” only. Based on comments received, FHFA determined it is not necessary to designate this rule as a prudential standard at this time. FHFA acknowledges that Enterprise failure to adhere to EHFP program standards can be addressed by other enforcement and supervision methods, and certain deficiencies may also be failures to meet existing PMOS standards that may trigger corrective action pursuant to section 4513(b) of the Safety and Soundness Act and 12 CFR part 1236.</P>
                <HD SOURCE="HD2">E. Section 1293.23, Resource Disclosures, Additions, and Clarifying Edits</HD>
                <P>In response to comments, FHFA has not included in the final rule proposed § 1293.23(b)(4), which would have required the Enterprises to submit a summary of the value of resources dedicated to supporting the outcomes categorized by type of activity and a summary of additional value of resources contributed from third parties because of the Enterprise's support of the outcomes. Instead, Enterprise accountability will be evaluated by FHFA's Rating System and performance metrics, including but not limited to accept rate gaps and home loan acquisitions. The Rating System will assess Enterprise reports, performance, and overall commitment to equity. FHFA also may consider implementing a financial disclosure requirement in a future rule and will examine the Enterprises' equitable housing finance planning under the rule.</P>
                <P>FHFA has made additions and clarifying edits to § 1293.23 in the final rule, including distinguishing between multifamily and single-family acquisition reporting, adding neighborhood race and ethnicity reporting where appropriate, adding narrative description requirements for the underwriting sections of the performance reports, adding a separate reporting requirement for all homeownership programs to facilitate better comparison between the Enterprises, and clarifying that FHFA may use its order authority under 12 U.S.C. 4514 to establish requirements for reporting.</P>
                <HD SOURCE="HD2">F. Section 1293.27, Program Evaluation</HD>
                <P>In response to comments, FHFA has added § 1293.27 “Program Evaluation” in the final rule, which provides that FHFA will publish on its website a narrative assessment evaluating each Enterprise's performance under its respective Equitable Housing Finance Planning program standards by May 15 of each year. FHFA believes this change will foster greater public transparency and Enterprise accountability, while reducing burden and complexity associated with developing separate evaluation metrics for public consumption. It will also further align the Equitable Housing Finance Program with the Community Reinvestment Act, in that both programs require review and public disclosure by their respective agencies of the performance of the entities they regulate.</P>

                <P>
                    In response to comments, FHFA has added a new Subpart D—Federal Home Loan Bank Equitable Housing Finance Planning in the final rule, requiring the Banks to report on any meaningful actions voluntarily taken to support underserved communities and such actions currently planned for the coming year, or to provide a public notice that it has not taken any voluntary actions and does not currently have any such voluntary meaningful actions planned for the coming year. This requirement recognizes the importance of addressing barriers to

                    sustainable housing for all regulated entities, while also recognizing and considering the differences between the Banks and Enterprises. FHFA may engage in future rulemaking and guidance specific to the Banks regarding equitable housing finance planning.
                </P>
                <HD SOURCE="HD1">IV. Consideration of Differences Between the Banks and the Enterprises</HD>
                <P>Under the final rule, both the Enterprises and the Banks would be subject to subpart A (§§ 1293.1 through 1293.3) and subpart B (§§ 1293.11 through 1293.12), including general provisions related to fair housing and fair lending laws, compliance, examinations, oversight, and enforcement. Additionally, both the Banks and the Enterprises would be covered by FHFA's authority to require regular and special reports and the requirement to certify compliance in regular reports. However, FHFA has not currently issued any reporting orders requiring regular or special fair housing and fair lending reports from the Banks. The Equitable Housing Finance Plan and broader equitable housing finance planning requirements described specifically in subpart C (§§ 1293.21 through 1293.26) would apply only to the Enterprises and would codify in regulation, and expand on, the existing equitable housing framework for the Enterprises that FHFA previously established. In response to comments, FHFA has added subpart D in the final rule which requires the Banks to report on any voluntary equitable housing finance actions taken or planned but does not require any actions by the Banks other than the reports or notices that there are no actions to report. Subpart E (§ 1293.41) could include data collection and reporting requirements that would apply to both the Enterprises and the Banks, but currently the requirements would apply only to the Enterprises.</P>
                <P>
                    When promulgating any regulation that may have future effect relating to the Banks, the Director is required by section 1313(f) of the Safety and Soundness Act to consider the differences between the Banks and the Enterprises with respect to the Banks' cooperative ownership structure, mission of providing liquidity to members, affordable housing and community development mission, capital structure, and joint and several liability.

                     FHFA requested comments from the public about whether differences related to these factors should result in a revision of the proposed rule as it relates to the Banks. FHFA's adoption of new subpart D in the final rule reflects its consideration of the comments and appropriate consideration of the differences between the Banks and the Enterprises. The Director considered the differences between the Banks and the Enterprises, as they relate to the above factors, and determined that this final rule is appropriate.

                    <E T="03">et seq.</E>

FHFA has considered the impact of the final rule under the Regulatory Flexibility Act.

                <HD SOURCE="HD1">Background</HD>
                <P>On September 16, 2019, Airbus applied for an amendment to Type Certificate No. A28NM to include the new Model A321neo XLR airplane. These airplanes are twin-engine, transport-category airplanes with seating for 244 passengers, and a maximum take-off weight of 222,000 pounds.</P>
                <HD SOURCE="HD1">Type Certification Basis</HD>
                <P>Under the provisions of 14 CFR 21.101, Airbus must show that the Model A321neo XLR airplane meets the applicable provisions of the regulations listed in Type Certificate No. A28NM, or the applicable regulations in effect on the date of application for the change, except for earlier amendments as agreed upon by the FAA.</P>
                <P>
                    If the Administrator finds that the applicable airworthiness regulations (
                    <E T="03">e.g.,</E>
                     14 CFR part 25) do not contain adequate or appropriate safety standards for the Airbus Model A321neo XLR airplanes because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16.
                </P>
                <P>Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same novel or unusual design feature, or should any other model already included on the same type certificate be modified to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under § 21.101.</P>
                <P>In addition to the applicable airworthiness regulations and special conditions, the Airbus Model A321neo XLR airplane must comply with the fuel-vent and exhaust-emission requirements of 14 CFR part 34, and the noise-certification requirements of 14 CFR part 36.</P>
                <P>The FAA issues special conditions, as defined in § 11.19, in accordance with § 11.38, and they become part of the type certification basis under 14 CFR 21.101.</P>
                <HD SOURCE="HD1">Novel or Unusual Design Feature</HD>
                <P>The Airbus Model A321neo XLR airplane will incorporate the following novel or unusual design feature:</P>
                <P>Flight-envelope protections, in icing and non-icing conditions, that use high- incidence protection and an alpha-floor function to automatically advance throttles when the airplane angle of attack (AoA) reaches a predetermined value.</P>
                <HD SOURCE="HD1">Discussion</HD>
                <P>The current airworthiness standards do not contain adequate safety standards for the high-incidence protection system and the alpha-floor system for the Airbus Model A321neo XLR series airplanes. This is because the FAA's current standards were designed for more traditional electronic flight control systems (EFCS), which involve less advanced envelope protections, such as stick shakers and pushers. These special conditions address the more advanced flight envelope protections, including icing and non-icing conditions, that are part of the EFCS design of the A321neo XLR airplane.</P>
                <P>
                    The high-incidence protection system prevents the airplane from stalling and, therefore, the stall warning system is not needed during normal flight conditions. However, during failure conditions which are not shown to be extremely improbable, the requirements of §§ 25.203 and 25.207 apply, although slightly modified by these conditions. If there are failures not shown to be extremely improbable, the flight characteristics at the angle-of-attack for C
                    <E T="52">LMAX</E>
                     must be suitable in the traditional sense, and stall warning must be provided in a conventional manner. These special conditions address the need for modification during icing conditions and non-icing conditions.

                    The FAA issued Notice of Special Conditions No. 25-23-03-SC for the Airbus Model A321neo XLR airplane. They were published in the 
                    <E T="04">Federal Register</E>

                    Boeing requested that the FAA add statements to sections (e)(1)(ii)(B) and (C) of the proposed special conditions regarding the demonstration of satisfactory lateral control at the aft stop and the consideration of rapid application of go-around power or thrust. Boeing requested these changes for consistency with the proposed regulatory material for § 25.202(d)(2) and (4) in the Flight Test Harmonization Working Group Phase 2 Rev A Final Report

                     (FTHWG Report). The FAA does not agree to this change. The FAA has previously published special conditions on this subject. The terms of those special conditions were consistent with the terms of these special conditions, and the FAA finds that they provide an adequate level of safety,

                    Boeing recommended the FAA add “and emergency” to the proposed special conditions regarding the alpha-floor setting not interfering with normal maneuvering because this change would be consistent with proposed regulatory material for § 25.144(a) in the FTHWG Report. The FAA declines to make this change. This special condition only addresses the alpha-floor setting in normal maneuvering. The general limiting special conditions

                <P>
                    Boeing requested the FAA revise the deceleration rate in icing conditions in section (e)(1)(ii)(C)(
                    <E T="03">2</E>
                    ) of the proposed special conditions to 3 knots per second because this change would be consistent with the Airbus Model A350-900 Special Conditions No. 25-517-SC part I section 5.1(b)(3)(ii) and the proposed regulatory material for § 25.202(d)(4) in the FTHWG Report. The FAA does not concur with Boeing's request because this change would not be appropriate for the design of the A321neo XLR. The XLR EFCS architecture is based on a previously certified architecture for the Airbus Model A321neo ACF. The A321neo ACF used a deceleration rate in icing conditions of 2 knots per second; therefore, using the same requirement for the A321neo XLR is appropriate and provides an adequate (equivalent) level of safety.
                </P>
                <P>Boeing requested the FAA revise section (e)(2)(i)(D) of the proposed special conditions related to buffeting to have the same requirement for icing and non-icing conditions, which Boeing said would also be consistent with 25-517-SC part II section 3(a)(2)(i) and the proposed regulatory material for 25.105(a)(2)(iii) in the FTHWG Report. Boeing stated that the requirement for icing conditions appears to indicate that buffet of a deterrent magnitude and severity would be acceptable for demonstration. The FAA does not concur with Boeing's request. The FAA does not intend the buffeting requirement for icing conditions to allow deterrent buffet. The wording of these special conditions is appropriate because the magnitude of the buffet can be a driver in setting the protections while still requiring the airplane be free from excessive vibration and buffet. Therefore, these special conditions provide an adequate level of safety.</P>
                <P>
                    Boeing requested that the FAA remove all notes under section (j) of the proposed special conditions; the notes mention a tolerance for take-off and climb-out speeds in icing. Boeing stated that the tolerance in the notes appears to expand the allowable degradation in performance prior to calculating the icing effect and that the removal of the notes would align with previously released special conditions on this topic, such as 25-517-SC, and the recommendations in the FTHWG Report. The FAA does not concur with Boeing's request. The A321neo XLR is a derivative of an airplane (A321neo ACF) initially certified with tolerances to account for ice effect on performance along the take-off path as well as at landing. In particular, it was not needed to account for icing if the ice effect on V
                    <E T="52">min</E>
                    1g was less than 5%/5kt. To reflect the intent of § 25.21(g) on airplanes for which § 25.21(g) is not applicable, Airbus has proposed a standard for the A321neo XLR consisting of the removal of the tolerance at landing and a reduced tolerance to 2.5%/2.5kt for take-off path. Airbus considers that the requirements of these special conditions provide an adequate level of safety based on the in-service performance of previous A321 models, and the FAA concurs.
                </P>
                <P>Airbus, the applicant, requested the FAA revise the special condition that the FAA proposed would apply in lieu of § 25.121(d)(2)(ii). Airbus provided updated wording that replaced the text presented in the notice with text inspired by the FTHWG report recommendations. Airbus stated that this text is comparable in intent to the text proposed by FAA in the notice but with an improved clarity thanks to a more modern wording, anticipating the future implementation of the FTHWG recommendations. The FAA concurs with this rationale and has modified the final special condition accordingly.</P>
                <P>Boeing commented that the formatting of the proposed special conditions related to § 25.121 could lead to confusion as to which regulations were being addressed due to missing paragraph numbers. The FAA concurs and has updated the format of the final special conditions to clarify.</P>
                <HD SOURCE="HD1">Applicability</HD>
                <P>As discussed above, these special conditions are applicable to the Airbus Model A321neo XLR airplane. Should Airbus apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, these special conditions would apply to that model as well.</P>
                <P>
                    Under standard practice, the effective date of final special conditions would be 30 days after the date of publication in the 
                    <E T="04">Federal Register</E>
                    . However, as the certification date for the Airbus Model A321neo XLR is imminent, the FAA finds that good cause exists to make these special conditions effective upon publication.

                <HD SOURCE="HD1">Background</HD>
                <P>
                    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all De Havilland Aircraft of Canada Limited Model DHC-8-401 and -402 airplanes. The NPRM published in the 
                    <E T="04">Federal Register</E>
                     on October 27, 2023 (88 FR 73775). The NPRM was prompted by AD CF-2022-59, dated October 27, 2022, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that new or more restrictive airworthiness limitations have been developed.
                </P>
                <P>In the NPRM, the FAA proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address new or more restrictive maintenance interval limitations. Failure to adhere to the specified interval limitations may result in reduced structural integrity of the airplane.</P>
                <P>
                    You may examine the MCAI in the AD docket at 
                    <E T="03">regulations.gov</E>
                     under Docket No. FAA-2023-2137.
                </P>
                <HD SOURCE="HD1">Discussion of Final Airworthiness Directive</HD>
                <HD SOURCE="HD1">Comments</HD>
                <P>The FAA received a comment from an individual who supported the NPRM without change.</P>
                <P>The FAA received additional comments from De Havilland Aircraft of Canada Limited and Horizon Air. The following presents the comments received on the NPRM and the FAA's response to each comment.</P>
                <HD SOURCE="HD1">Request To Update the Number of Affected Airplanes</HD>
                <P>De Havilland requested that the Costs of Compliance section of the NPRM be updated to show the correct number of affected airplanes.</P>
                <P>The FAA agrees. The Costs of Compliance section of this AD has been updated to show 52 affected airplanes.</P>
                <HD SOURCE="HD1">Request To Require Tasks as Mandated in the MCAI</HD>
                <P>Horizon Air requested that the proposed AD directly mandate maintenance review board report (MRBR) tasks instead of Aircraft Maintenance Manual (AMM) tasks. Horizon noted that Transport Canada AD CF-2022-59 mandates MRBR tasks directly, and that using the AMM tasks would put an additional burden on the operator to monitor multiple sources for the same tasks. The commenter also asserted that AMM task 77-31-00-710-803, which would be required by the proposed AD, adds MRBR tasks 731100-203, 733100-201, 740000-201, 750000-201, 772100-202, and 793000-201. These tasks are not identified in Section 7-00, PSM 1-84-7—Maintenance Requirements Manual—Part 2 ALI.</P>
                <P>The FAA does not agree because the FAA has decided to not mandate MRBRs that are part of Candidate Certification Maintenance Requirements (CCMRs), which are required by Transport Canada AD CF-2022-59. Instead of mandating the CCMR as done in the Transport Canada AD, the FAA, after coordination with Transport Canada, determined the corresponding AMM task numbers will be used. With the AMM tasks, operators must check for all engine fault codes at once, which involves reading codes from the engine fault code indicator. Although this involves more tasks, it does not add a significant number of steps. Requiring the AMM task does not pose a significant burden on the operator. This AD has not been changed with regard to this request.</P>
                <HD SOURCE="HD1">Request To Limit Required Tasks to Procedure Section</HD>
                <P>Horizon Air requested that the proposed AD require only the procedure section of the AMM, with provisions for equivalent tooling and materials, rather than requiring the entire AMM maintenance task, including the job set-up, specific tools, equipment, and close-out sections. The commenter stated that mandating the entire AMM maintenance task procedure may restrict the operator's ability to perform other maintenance along with AMM tasks.</P>
                <P>The FAA does not agree. The job set-up and close-out procedures are essential for ensuring the safety of maintenance personnel, and for ensuring the correct completion of the AMM task. This AD has not been changed with regard to this request.</P>
                <HD SOURCE="HD1">Request To Allow Further AMM Revisions</HD>
                <P>Horizon Air requested clarification of whether future revisions of the AMM are allowed. Horizon noted that the proposed AD did not address whether task changes such as additions, removals, and interval adjustments could cause an operator to be out of compliance with the rule as issued.</P>
                <P>The FAA agrees to clarify. Using the current revision of the AMMs or other revisions that incorporate the information specified in paragraph (g) of this AD is acceptable for compliance with this AD. This AD does not mandate using a specific revision of the AMM, provided that the revision used complies with the requirements of paragraph (g) of this AD.</P>
                <HD SOURCE="HD1">Conclusion</HD>
                <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 reviewed the relevant data, considered the comments received, and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, and any other changes described previously, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator.</P>
                <HD SOURCE="HD1">Costs of Compliance</HD>
                <P>The FAA estimates that this AD affects 52 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:</P>
                <P>
                    The FAA has determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the agency 
                    <PRTPAGE P="42794"/>
                    estimates the average total cost per operator to be $7,650 (90 work-hours × $85 per work-hour).
                </P>
                <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>This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.</P>
                <P>For the reasons discussed above, I certify that this AD:</P>
                <P>(1) Is not a “significant regulatory action” under Executive Order 12866,</P>
                <P>(2) Will not affect intrastate aviation in Alaska, and</P>
                <P>(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.</P>

                <HD SOURCE="HD1">Authority for This Rulemaking</HD>
                <P>The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies the Air Traffic Service (ATS) route structure as necessary to preserve the safe and efficient flow of air traffic within the National Airspace System.</P>

                    This action amends 14 CFR part 71 by amending VOR Federal airways V-44, V-128, and V-493, and United States RNAV routes T-315 and T-323. The FAA is taking this action due to the planned decommissioning of the VOR portion of the York, KY, VORTAC NAVAID. The ATS route actions are described below.

                <P>
                    <E T="03">V-44:</E>
                     Prior to this final rule, V-44 extended between the Columbia, MO, VOR/Distance Measuring Equipment (VOR/DME) and the Centralia, IL, VORTAC; and between the Falmouth, KY, VOR/DME and the Albany, NY, VORTAC. The airspace below 2,000 feet mean sea level (MSL) outside the United States was excluded. The airway segment between the Falmouth VOR/DME and the Parkersburg, WV, VORTAC is removed. As amended, the airway is changed to now extend between the Columbia VOR/DME and the Centralia VORTAC, and between the Parkersburg VORTAC and the Albany VORTAC.
                </P>
                <P>
                    <E T="03">V-128:</E>
                     Prior to this final rule, V-128 extended between the Brickyard, IN, VORTAC and the Casanova, VA, VORTAC. The airway segment between the Cincinnati, OH, VORTAC and the Charleston, WV, VORTAC is removed. As amended, the airway is changed to now extend between the Brickyard VORTAC and the Cincinnati VORTAC, and between the Charleston VORTAC and the Casanova VORTAC.
                </P>
                <P>
                    <E T="03">V-493:</E>
                     Prior to this final rule, V-493 extended between the Livingston, TN, VOR/DME and the Appleton, OH, VORTAC. The airway segment between the Lexington, KY, VOR/DME and the Appleton VORTAC is removed. As amended, the airway is changed to now extend between the Livingston VOR/DME and the Lexington VOR/DME.
                </P>
                <P>
                    <E T="03">T-315:</E>
                     Prior to this final rule, T-315 extended between the JARLO, WV, waypoint (WP) and the Burlington, VT, VORTAC. The route is extended westward from the JARLO WP to the JIMUR, KY, Fix which is located approximately 1.1 nautical miles (NM) east northeast from the Cincinnati, KY, VORTAC and will be charted when the York VOR is decommissioned. The route extension will include the CALIF, KY, Fix and the ILILE, OH, Fix which is being converted to a WP when the York VOR is decommissioned. As amended, T-315 is changed to now extend between the JIMUR, KY, Fix and the Burlington, VT, VORTAC. The full T-315 route description is listed in the amendments to part 71 as set forth below.
                </P>
                <P>
                    <E T="03">T-323:</E>
                     Prior to this final rule, T-323 extended between the MARQO, FL, WP and the DACEL, KY, WP. The route is extended northward from the DACEL WP to the Appleton, OH, VORTAC. The route extension includes the ZELID, KY, WP which is being established approximately 2.1 NM southeast from the York, KY, VORTAC and the ROHDE, OH, Fix which is being converted to a WP when the York VOR is decommissioned. As amended, T-323 is changed to now extend between the MARQO WP and the Appleton VORTAC. The full T-323 route description is listed in the amendments to part 71 as set forth below.
                </P>
                <P>The NAVAID radials listed in the VOR Federal Airway descriptions in the regulatory text of this final rule are unchanged and stated in degrees True north.</P>
                <HD SOURCE="HD1">Regulatory Notices and Analyses</HD>
                <P>The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.</P>

                <P>
                    The FAA has determined that this action of amending VOR Federal Airways V-44, V-128, and V-493, and United States RNAV Routes T-315 and T-323, due to the planned decommissioning of the VOR portion of the York, KY, VORTAC NAVAID, qualifies for categorical exclusion under the National Environmental Policy Act (42 U.S.C. 4321 
                    <E T="03">et seq.</E>
                    ) and its implementing regulations at 40 CFR part 1500, and in accordance with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, paragraph 5-6.5a, which categorically excludes from further environmental impact review rulemaking actions that designate or modify classes of airspace areas, airways, routes, and reporting points (see 14 CFR part 71, Designation of Class A, B, C, D, and E Airspace Areas; Air Traffic Service Routes; and Reporting Points); and paragraph 5-6.5i, which categorically excludes from further environmental impact review the establishment of new or revised air traffic control procedures conducted at 3,000 feet or more above ground level (AGL); procedures conducted below 3,000 feet AGL that do not cause traffic to be routinely routed over noise sensitive areas; modifications to currently approved procedures conducted below 3,000 feet AGL that do not significantly increase noise over noise sensitive areas; and increases in minimum altitudes and landing minima. As such, this action is not expected to result in any potentially significant environmental impacts. In accordance with FAA Order 1050.1F, paragraph 5-2 regarding Extraordinary Circumstances, the FAA has reviewed this action for factors and circumstances in which a normally categorically excluded action may have a significant environmental impact requiring further analysis. The FAA has determined that no extraordinary circumstances exist that warrant preparation of an environmental assessment or environmental impact study.

                <HD SOURCE="HD1">Authority for This Rulemaking</HD>
                <P>The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it modifies Class E airspace to support IFR operations at Edward G. Pitka Sr. Airport, Galena, AK.</P>

                <P>
                    The FAA published a notice of proposed rulemaking for Docket No. FAA-2023-2482 in the 
                    <E T="04">Federal Register</E>
                     (89 FR 2520; January 16, 2024), proposing to amend Class E airspace at Edward G. Pitka Sr, Airport, Galena, AK. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received.
                </P>
                <HD SOURCE="HD1">Differences From the NPRM</HD>
                <P>When identifying the Class E airspace extending upward from 700 feet or more above the surface of the earth, an inadvertent text was entered in line one of the text header for type of airspace. The appropriate designation of E5 was entered in the airport's legal texts in the Final Rule.</P>

                    Class E2 and E5 airspace areas are published in paragraph 6002 and 6005, respectively, of FAA Order JO 7400.11, Airspace Designations and Reporting Points, which is incorporated by reference in 14 CFR 71.1 on an annual basis. This document amends the current version of that order, FAA Order JO 7400.11H, dated August 11, 2023, and effective September 15, 2023. FAA Order JO 7400.11H is publicly available as listed in the 
                    <E T="02">ADDRESSES</E>
                     section of this document. These amendments will be published in the next update to FAA Order JO 7400.11.
                </P>
                <P>FAA Order JO 7400.11H lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.</P>
                <HD SOURCE="HD1">The Rule</HD>
                <P>This action amends 14 CFR part 71 by modifying the Class E airspace area designated as a surface area and modifying the Class E airspace extending upward from 700 feet above the surface at Edward G. Pitka Sr. Airport, Galena, AK.</P>
                <P>The Class E airspace area designated as a surface area is reduced to 4.1-mile radius around the airport. The reduction in airspace efficiently contains IFR departure operations until reaching 700 feet above the surface or the next adjacent controlled airspace.</P>
                <P>The Class E airspace area extending upward from 700 feet above the surface is modified to contain aircraft executing IFR arrival procedures descending through 1,500 feet above the surface. The modification more appropriately contains the airport's instrument arrival approaches' final bearings and final bearing protected airspaces.</P>
                <P>Finally, the FAA amended the airport's legal description. The airport's geographic coordinates have been updated to match the FAA's database.</P>
                <HD SOURCE="HD1">Regulatory Notices and Analyses</HD>
                <P>The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.</P>
                <HD SOURCE="HD1">Environmental Review</HD>
                <P>The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with FAA Order 1050.1F, “Environmental Impacts: Policies and Procedures,” paragraph 5-6.5.a. This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.</P>

                <HD SOURCE="HD1">II. Background, Purpose, and Legal Basis</HD>
                <P>On February 2, 2024, Orsted, an offshore wind farm developer, notified the Coast Guard that they plan to begin construction of the Revolution Wind facilities in the Revolution Wind Farm (RWF) project area within federal waters on the Outer Continental Shelf (OCS), specifically in the Bureau of Ocean Energy Management (BOEM) Renewable Energy Lease Area OCS-A 0486, approximately 15 nautical miles (NM) offshore southeast of Point Judith, Rhode Island, 32 NM southeast of the Connecticut coast and 12 NM southwest of Martha's Vineyard, Massachusetts in June 2024.</P>
                <P>After determining that establishment of safety zones was necessary to provide for the safety of life, property, and the environment during the anticipated construction of the structures, on March 21, 2024, the Coast Guard published a notice of proposed rulemaking (NPRM) titled “Safety Zone; Revolution Wind Farm Project Area, Outer Continental Shelf, Lease OCS-A 0486, Offshore Rhode Island, Atlantic Ocean” (89 FR 20150). There we explained the basis for the NPRM and invited comments on our proposed regulatory action related to the establishment of safety zones around the construction of 65 Wind Turbine Generators (WTG) and two Offshore Sub Stations (OSS) located in the RWF project area. Eighty-six comments were received during the comment period that ended April 22, 2024.</P>
                <P>
                    Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause exists for making this rule effective less than 30 days after publication in the 
                    <E T="04">Federal Register</E>
                    . The comment period for the NPRM associated with the RWF project area ended on April 22, 2024, and construction for the project has already begun. Thus, there is insufficient time to allow for 30-days before the rule becomes effective. Delaying the effective date of this rule would be contrary to public interest because immediate action is needed to respond to the potential safety risks associated with the extremely complex and unusually hazardous construction of these OCS facilities including hydraulic pile driving hammer operations, heavy lift operations, overhead cutting operations, potential falling debris, increased vessel traffic, and stationary barges in close proximity to the facilities and each other, occurring at times within 12 NM of shore.
                </P>
                <P>Based on these circumstances, the First Coast Guard District Commander has determined that establishment of 67 safety zones through rulemaking is warranted to ensure the safety of life, property, and the environment within a 500-meter radius of each of the 67 facilities during their construction.</P>
                <HD SOURCE="HD1">III. Legal Authority and Need for Rule</HD>
                <P>The Coast Guard is issuing this rule under the authority provided in 14 U.S.C. 544, 43 U.S.C. 1333, and Department of Homeland Security (DHS) Delegation No. 00170.1, Revision No. 01.3. As an implementing regulation of this authority, 33 CFR part 147 permits the establishment of safety zones for non-mineral energy resource permanent or temporary structures located on the OCS for the purpose of protecting life and property on the facilities, appurtenances and attending vessels, and on the adjacent waters within the safety zone (see 33 CFR 147.10). Accordingly, a safety zone established under 33 CFR part 147 may also include provisions to restrict, prevent, or control certain activities, including access by vessels or persons to maintain safety of life, property, and the environment.</P>
                <HD SOURCE="HD1">IV. Discussion of Comments, Changes, and the Rule</HD>
                <P>
                    As noted above, the Coast Guard received 86 public comments on the NPRM published March 21, 2024. Three of the 86 comments were supportive of the 67 temporary 500-meter safety zones while the remaining 83 were opposed. One commenter who supported the rulemaking, provided three recommendations. Another supporter of our proposed rule sought clarification of the rule in their comment. A third supporter of the rule requested the Coast Guard consider conducting a radar interference and additional studies. Those opposing the NPRM communicated this opposition relative to wind farm construction in general and not necessarily regarding our proposed rule and the enforcement of 
                    <PRTPAGE P="42800"/>
                    safety zones around this construction. Six commenters expressed specific opposition to taxpayer dollars being used for the enforcement of safety zones around the construction of private facilities and stated that the developer should be held responsible for the financial burden. Three commenters expressed their concerns with our review of the Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) without any further specificity on their contentions. One commenter questioned the need for safety zones for this particular offshore construction project as compared to offshore drilling platforms in the Gulf of Mexico. We provide a detailed discussion below in response to each comment.
                </P>
                <P>One commenter who agreed with our proposed rule to create 67 temporary 500-meter safety zones during construction of these OCS facilities to protect life, property, and the environment, and supported the proposed rule, offered three recommendations for the Coast Guard to consider.</P>
                <P>First, the commenter expressed their concern that a 500-meter safety zone was insufficient and recommended we extend the safety zones 500-meters by originating the measurement from the outer perimeter of attending, primary construction vessels once those vessels have achieved stationary position to conduct construction activities vice from the center point of the construction site. For clarity and consistency for mariners working in and transiting the area, we believe that enforcement of the 500-meter zone from the center point of construction as a fixed geographic position is most appropriate for this offshore construction project. Using the center point of construction to base the location of the safety zone ensures there is a balance between ensuring safety and reducing impact on vessel transit.</P>
                <P>Second, the commenter recommended we clarify the term “local officer” as used in the definition of “designated representative” and expand the definition of “designated representative” to include an appropriate employee or contractor of Orsted to facilitate navigation around and through the safety zones and enhance effective communications when safety zones are enforced. We agree with the recommendation to clarify term “local officer” and will add the following definition in the regulatory text: the term “local officer” as used in the definition “designated representative” for this rulemaking means “any officer, agent, or employee of a unit of local government authorized by law or by a local government agency to engage in or supervise the prevention, detection, investigation, or prosecution of any violation of criminal law.” However, the Coast Guard does not agree with the commenter's other recommendation to expand the definition of “designated representative” in our proposed rule to include employees of Orsted, or their contractors. The Coast Guard finds no compelling need to broaden the definitional reach of the term “designated representative” or the authority to permit passage through and around the enforced safety zone based on the particular details of this offshore construction project, to include, the short duration of the enforcement period (possibly lasting less than one week depending on weather and other factors), the reduced vessel traffic in areas of construction, and the types of larger vessels that are most likely to navigate in the vicinity of the safety zones (commercial shipping, fishing, larger recreational vessels, and tugs with tows). The details of this offshore construction project suggest that those currently included in the definition of “designated representative” can properly ensure enforcement and administration of the rulemaking. Moreover, maintaining designation to Coast Guard Patrol Commander, including a Coast Guard coxswain, petty officer, or other officer operating a Coast Guard vessel and a Federal, State, and local officer designated by or assisting the First Coast Guard District Commander in the enforcement of the safety zones will ensure consistent application.</P>
                <P>Finally, the commenter suggested the Coast Guard not specify the duration that a safety zone may be enforced during active construction to accommodate delays in construction due to weather and other factors. In a previous similar offshore construction project, the developer estimated a 48-hour total active construction time, which translated to an estimated 48-hour enforcement period for each phase of the project. For this offshore construction project, the developer finds the 48-hour timeframe to be unrealistic, however. We do believe that providing an estimated time frame of safety zone enforcement is important to help the mariner understand any impacts on their intend voyage and alter course as needed and agree with the commenter that delays due to weather and other factors may extend the original period of construction. Accordingly, the Coast Guard finds that an enforcement period correlated to a regularly updated date range published in the weekly Local Notice to Mariners (LNM) is the best option because it is easily interpreted, reliable, and enforceable risk mitigation. Therefore, for this project and for voyage planning purposes, mariners should understand that it is possible that the enforcement period for a safety zone cited in the LNM could last for the entirety of the week due to the uncertainty of the active construction period. If active construction at a particular facility is completed before publishing of the next weekly LNM, a Broadcast Notice to Mariners (BNM) will broadcast the suspension of safety zone enforcement. As stated in our proposed rule, the Coast Guard's intention in enforcing safety zones during active construction and suspending enforcement when there is no construction is to reduce the regulatory burden on the mariner.</P>
                <P>
                    One commenter supported our proposed rule to create 67 temporary 500-meter safety zones during construction of these OCS facilities to protect life, property, and the environment, but requested additional clarification to the rule. The commenter specifically asked, “how many safety zones would be active at any given time?” The Coast Guard's response is, the 67 temporary safety zones could be enforced individually or simultaneously at several locations for a period lasting up to one week as construction progresses throughout the RWF project area. The commenter also asked, “will there be a website to check the open or closed zones, which is updated regularly?” In response, the Coast Guard will make notice of each enforcement period via the LNM and issue a BNM via marine channel 16 (VHF-FM) as soon as practicable in response to an emergency or hazardous condition. The First Coast Guard District LNM can be found at: 
                    <E T="03">http://www.navcen.uscg.gov.</E>
                     The commenter also asked, “since each zone is 
                    <FR>1/4</FR>
                     mile and the pilings are 1 mile apart, there's a 
                    <FR>1/2</FR>
                     mile corridor between each and all, correct?” In response, this is generally correct but not exact and in some instances the distance may be considerably less than a 
                    <FR>1/2</FR>
                     nm. We interpret the commenter's question to be aimed at determining if a safety zone is being enforced at adjacent facilities simultaneously what would be the available sea lane for a vessel to transit safely between the safety zones. In response to this interpretation, when enforced, there will be a 500-meter regulated area around the construction of each facility. The mariner may consider each facility to be roughly built, based on guidelines, at approximately 1 nm spacing. In 
                    <PRTPAGE P="42801"/>
                    addition, the mariner should account for the amount of spacing between facilities base on the vessel's direction of travel and the orientation of the facilities to each other and the vessel. The Coast Guard recommends that mariners transiting in the vicinity of the wind energy construction areas to maintain a proper watch and assess all risk factors during its voyage. Lastly, the commenter asked, “has the company provided a construction timeline for the work, perhaps by name (AE06 for example) and sector?” Additional information about the construction process of the RWF project area can be found at

                </P>
                <P>One commenter agreed with our proposed rule to create 67 temporary 500-meter safety zones during construction of these OCS facilities to protect life, property, and the environment but, requested the Coast Guard consider conducting a radar interference and additional studies. The commenter also stated that the economic impacts of the RWF have not been analyzed by BOEM correctly and therefore the Coast Guard is now required to conduct the analysis.</P>
                <P>The commenter expressed their concerns about possible radar interference and the Coast Guard's ability to operate and conduct search and rescue within RWF and requested the Coast Guard conduct additional studies and modeling analysis as a part of this rule. The Coast Guard acknowledges these concern and requests. However, the purpose of this rulemaking is to establish 67 temporary safety zones around the construction of each facility during the development of the RWF project area, which is unrelated to the commenter's concerns. Also, the First Coast Guard District has factored applicable statutes and regulations into this rule, as cited in Section III.</P>
                <P>The same commenter also stated that the economic impacts of the RWF have not been analyzed by BOEM as part of the FEIS correctly and therefore this analysis is now required to be conducted be the Coast Guard. While this rule may affect some owners or operators of small entities, the Coast Guard believes these safety zones will have a minimal economic impact because the safety zones are temporarily enforced, allow for deviation requests, and do not significantly impact transits. Vessels will only be prohibited from the regulated zone during periods of actual construction activity. The Coast Guard anticipates the enforcement period at each location to last anywhere from 48-hours to less than one week. Vessel traffic will be able to pass safely around each safety zone using an alternate route. Use of an alternate route will likely cause minimal delay for vessels in reaching their destination depending on other traffic in the area and vessel speeds. Vessels will be permitted to request deviations from this rule to transit through a safety zone. Such requests would be considered on a case-by-case basis and may be authorized by the First Coast Guard District Commander.</P>
                <P>Six commenters expressed specific opposition to taxpayer dollars being used for the enforcement of safety zones around the construction of private facilities and stated that the developer should be held responsible for the financial burden. The Coast Guard acknowledges these comments and concerns. Coast Guard authorities direct us to assess the potential safety risks associated with such complex and unusually hazardous construction projects, whether publicly or privately funded, and require establishment of the safety zones to ensure the safety of life, property, and the environment when such hazards exist.</P>
                <P>Three commenters expressed their concerns with our review generally of the Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) which requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Without having a more specific understanding of the commenters concerns to comment on, the Coast Guard maintains the belief that this rule would not result in any expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year.</P>
                <P>One commenter questioned the need for safety zones for this offshore construction project as compared to offshore drilling in the Gulf of Mexico. The Coast Guard acknowledges this comment but disagrees. Although there are some similarities between offshore wind facilities and offshore drilling platforms, the Coast Guard finds significant differences exist, warranting different considerations in the assessment for safety zones. The Coast Guard would also like to stress that this rule focuses on the enforcement of safety zones during the initial active construction of the facility, which will cease upon completion and installation, not the establishment of permanent safety zones. As we stated in our NPRM, the extremely complex offshore construction of these OCS facilities presents many unusually hazardous conditions including hydraulic pile driving hammer operations, heavy lift operations, overhead cutting operations, potential falling debris, increased vessel traffic, and stationary barges in close proximity to the facilities and each other. Based on these circumstances, the First Coast Guard District Commander has determined that establishment of 67 temporary safety zones through rulemaking is warranted to ensure the safety of life, property, and the environment within a 500-meter radius of each of the 67 facilities during their construction. Additionally, the Coast Guard is establishing these 67 safety zones to be temporary in nature and only effective and enforceable during periods of active construction through May 31, 2027. If the project is completed before May 31, 2027, enforcement of the safety zones will be suspended, and notice given via LNM. Any desire by the Coast Guard to create permanent safety zones would require addition notice and comment rulemaking.</P>
                <P>After considering the comments discussed above, the Coast Guard determined that no additional changes other than adding a definition for “local officer” should be made to the regulatory text based on these comments. As written, the Coast Guard believes that the rule ensures consistency, sufficient notice, and improved safety while minimizing impact on vessel transit.</P>
                <P>There is one change to the regulatory text of this rule from the NPRM. As discussed in comments above, we are adding a definition to the term “local officer”. The term “local officer” as used in the definition “designated representative” for this rulemaking means “any officer, agent, or employee of a unit of local government authorized by law or by a local government agency to engage in or supervise the prevention, detection, investigation, or prosecution of any violation of criminal law.”</P>
                <P>This rule establishes 67 temporary 500-meter safety zones around the construction of 65 WTGs and two OSS on the OCS from June 1, 2024, through 11:59 p.m. on May 31, 2024.</P>
                <P>
                    The 67 temporary safety zones could be enforced individually or simultaneously at several locations for a period lasting up to one week as construction progresses throughout the RWF project area. The Coast Guard will 
                    <PRTPAGE P="42802"/>
                    make notice of each enforcement period via the LNM and issue a BNM via marine channel 16 (VHF-FM) as soon as practicable in response to an emergency or hazardous condition. The Coast Guard is publishing this rulemaking to be effective, and enforceable, through May 31, 2027, to encompass any construction delays due to weather or other unforeseen circumstances. If the project is completed before May 31, 2027, enforcement of the safety zones will be suspended, and notice given via Local Notice to Mariners.

                <P>When enforced, no unauthorized vessel or person would be permitted to enter the safety zone without obtaining permission from the First Coast Guard District Commander or a designated representative. Requests for entry into the safety zone would be considered and reviewed on a case-by-case basis. Persons or vessels seeking to enter the safety zone must request authorization from the First Coast Guard District Commander or designated representative via VHF-FM channel 16 or by phone at 866-842-1560 (First Coast Guard District Command Center). If permission is granted, all persons and vessels shall comply with the instructions of the First Coast Guard District Commander or designated representative.</P>
                <P>The regulatory text appears at the end of this document.</P>
                <HD SOURCE="HD1">IV. Regulatory Analyses</HD>
                <P>We developed this rule after considering numerous statutes and Executive Orders related to rulemaking. A summary of our analyses based on these statutes and Executive Orders follows.</P>
                <HD SOURCE="HD2">A. Regulatory Planning and Review</HD>
                <P>Executive Orders 12866 and 13563 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. This TFR has not been designated a “significant regulatory action,” under Executive Order 12866. Accordingly, the TFR has not been reviewed by the Office of Management and Budget (OMB).</P>
                <P>Aligning with 33 CFR 147.15, the safety zones established would extend to a maximum distance of 500-meters around the OCS facility measured from its center point. Vessel traffic would be able to safely transit around the safety zones, which would impact a small, designated area in the Atlantic Ocean, without significant impediment to their voyage. This safety zone would provide for the safety of life, property, and the environment during the construction of each structure, in accordance with Coast Guard maritime safety missions.</P>
                <HD SOURCE="HD2">B. Impact on Small Entities</HD>
                <P>The Regulatory Flexibility Act of 1980, 5 U.S.C. 601-612, as amended, requires Federal agencies to consider the potential impact of regulations on small entities during rulemaking. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000. The Coast Guard certifies under 5 U.S.C. 605(b) that this rule would not have a significant economic impact on a substantial number of small entities.</P>
                <P>This rule may affect owners or operators of vessels intending to transit or anchor in the RWF, some of which might be small entities. However, these safety zones would not have a significant economic impact on a substantial number of these entities because they are temporarily enforced, allow for deviation requests, and do not impact vessel transit significantly. Regarding the enforcement period, although these safety zones would be in effect from June 1, 2024, through May 31, 2027, vessels would only be prohibited from the regulated zone during periods of actual construction activity in correspondence to the period of enforcement. We expect the enforcement period at each location to last approximately 48-hours to one week, as construction progresses throughout the RFW project area. Additionally, vessel traffic could pass safely around each safety zone using an alternate route. Use of an alternate route likely will cause minimal delay for the vessel in reaching their destination depending on other traffic in the area and vessel speed. Vessels would also be able to request deviation from this rule to transit through a safety zone. Such requests would be considered on a case by-case basis and may be authorized by the First Coast Guard District Commander or a designated representative. For these reasons, the Coast Guard expects any impact of this rulemaking establishing a temporary safety zone around these OCS facilities to be minimal and have no significant economic impact on small entities.</P>
                <P>
                    If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this rule would have a significant economic impact on it, please submit a comment (see 
                    <E T="02">ADDRESSES</E>
                    ) explaining why you think it qualifies and how and to what degree this rule would economically affect it.
                </P>
                <P>
                    Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we want to assist small entities in understanding this rule. If the rule would affect your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance, please call or email the person listed in the 
                    <E T="02">FOR FURTHER INFORMATION CONTACT</E>
                     section. The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard.

                <P>This rule would not call for a new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).</P>
                <HD SOURCE="HD2">D. Federalism and Indian Tribal Governments</HD>
                <P>A rule has implications for federalism under Executive Order 13132 (Federalism), if it has a substantial direct effect on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government. We have analyzed this rule under that Order and have determined that it is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132.</P>
                <P>
                    Also, this rule does not have tribal implications under Executive Order 13175 (Consultation and Coordination with Indian Tribal Governments) because it would not have a substantial direct effect 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>The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Though this rule would not result in such an expenditure, we do discuss the potential effects of this rule elsewhere in this preamble.</P>

                    We have analyzed this rule under Department of Homeland Security Directive 023-01, Rev. 1, associated implementing instructions, and Environmental Planning COMDTINST 5090.1 (series), which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made a preliminary determination that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. This rule involves the establishment of a safety zone around an OCS facility to protect life, property, and the marine environment. It is categorically excluded from further review under paragraph L60 of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 1. A Record of Environmental Consideration supporting this determination is available in the docket. For instructions on locating the docket, see the

                    <E T="03">Background:</E>
                     On December 21, 2023, we published a document in the 
                    <E T="04">Federal Register</E>
                     (88 FR 88381) (December 2023 proposed waiver and extension) proposing to waive 
                    <E T="03">34 CFR 75.250</E>
                     and extend the project period under 
                    <E T="03">34 CFR 75.261(c)(2</E>
                    ) for TCPCTIP under the Carl D. Perkins Career and Technical Education Act of 2006 (Perkins V). These regulations generally limit project periods to 60 months and restrict project period extensions involving the obligation of additional Federal funds. In the December 2023 proposed waiver and extension, the Secretary also proposed to: (1) extend the project period for current TCPCTIP grantees through FY 2027, if Congress continues to appropriate funds under the existing program authority; and (2) not announce a new competition or make new awards until FY 2027.
                </P>
                <P>
                    <E T="03">Public Comment:</E>
                     In the December 2023 proposed waiver and extension, we invited comments about the potential effect the proposed waiver and extension would have on TCPCTIP and on applicants that may be eligible to apply for grant awards under any new TCPCTIP notice inviting applications, should there be one. In response to our invitation in the December 2023 proposed waiver and extension, two parties provided responsive comments.
                </P>
                <P>
                    <E T="03">Analysis of Comments and Changes:</E>
                     An analysis of the comments we received on the proposed waiver and extension follows. There are no substantive differences between the proposed waiver and extension and the final waiver and extension.
                </P>
                <P>
                    <E T="03">Comment:</E>
                     The first commenter supported the waiver and extension of the comment period for TCPCTIP, pointing out that: (1) no entities other than Navajo Technical University (NTU) and United Tribes Technical College (UTTC) meet the definition of a “tribally controlled postsecondary career and technical institution” in section 3(52) of Perkins V (20 U.S.C. 2302(52)) and the criteria in section 117 of Perkins V (20 U.S.C. 2327(d)); and (2) there is no indication that another entity has ever applied for TCPCTIP. The commenter further noted that a Native American or Alaska Native Tribe will not take the steps necessary to establish and support a TCPCTIP because it is easier for a Tribe to establish a Tribally Controlled College or University that meets the requirements to receive funding under title I of the Tribally Controlled Colleges and Universities Assistance Act of 1978 (TCCUAA; 25 U.S.C. 1801 
                    <E T="03">et seq.</E>
                    ), which requires at least one year of operation prior to making an application with a majority of students who are Indians (TCCUAA, section 103(3); 25 U.S.C. 1804(3)), as opposed to the three years of operation prior to making an application for participation in the TCPCTIP (Perkins V, section 3(52)(E); 20 U.S.C. 2302(52)(E)).
                </P>
                <P>The commenter also recommended that in the event a Tribe expresses interest in establishing a TCPCTIP that meets the requirements of the program, the Department of Education (ED) should consult with Tribes, Tribal Colleges and Universities, and the Department of the Interior's (DOI's) Bureau of Indian Education (BIE) to ensure consistency in the application process, including ensuring the completion of a satisfactory feasibility study.</P>
                <P>In addition, for future competitions, the commenter proposed that ED should take steps to ensure that existing grantees are held harmless should a new institution be deemed fundable, specifically, urging ED to establish a “hold-harmless provision,” which would ensure that funding for existing grantees would not be reduced below the prior year's level.</P>
                <P>
                    <E T="03">Discussion:</E>
                     We appreciate the commenter's support for the TCPCTIP waiver and extension. We will continue to work with Tribes, Tribal Colleges and Universities, and the DOI's BIE to ensure consistency in the TCPCTIP application process so that all applicants meet the same requirements. We note, however, that neither section 
                    <PRTPAGE P="42807"/>
                    3(52) of Perkins V (20 U.S.C. 2302(52)), which defines “tribally controlled postsecondary career and technical institution,” nor section 117 of Perkins V (20 U.S.C. 2327), which authorizes funding for TCPCTIP, requires an applicant to complete a feasibility study. Also, neither section 3(52) or section 117 of Perkins V (20 U.S.C. 2302 (52), 2327) includes a hold-harmless provision. Because a feasibility study and adding a hold-harmless provision are outside the scope of the proposed waiver and extension, we decline to make the suggested changes.
                </P>

                    <E T="03">Comment:</E>
                     The second commenter stated that deviation from standard grant making practice should only be considered where it is fully evident that no other organizations could apply for, and make use of, grant funds, and expressed concern that the proposed extension of the grant period would have the unintended consequence of limiting the ability of a new organization to access TCPCTIP funds. The commenter opposed the waiver and extension of the project period for the TCPCTIP through FY 2027 and proposed that a new competition should be held to provide the opportunity for new organizations to fairly compete for grant funds and that failing to hold a new competition only benefits the existing grantees.
                </P>
                <P>
                    <E T="03">Discussion:</E>
                     There are no entities besides NTU and UTTC that meet the requirements in the definition of “tribally controlled postsecondary career and technical institution” in section 3(52)(E) of Perkins V (20 U.S.C. 2302(52)(E)) and the eligibility requirements in section 117(a) (20 U.S.C. 2327(a)), which specifies that an applicant may not receive Federal assistance under title I of the Tribally Controlled Colleges and Universities Assistance Act of 1978 (25 U.S.C. 1801 
                    <E T="03">et seq.</E>
                    ) or the Navajo Community College Act (Pub. L. 92-189, as amended) to be eligible to apply for a TCPCTIP grant. On September 5, 2023, the Department solicited Tribal input on the proposed waiver and extension for TCPCTIP, pursuant to Executive Order 13175, Consultation and Coordination With Indian Tribal Governments. We asked during that consultation whether participants were aware of any other entity that is or will be eligible to apply for TCPCTIP prior to FY 2025. Participants did not identify any other entities that are or will be eligible for TCPCTIP during the consultation or its written comment period that ended October 5, 2023. The Department also did not receive any comments from entities that are or seek to be eligible to apply for TCPCTIP grant funds during the 30-day public comment period for this waiver and extension.
                </P>
                <P>Moreover, as noted earlier, the definition of “tribally controlled postsecondary career and technical institution” requires an institution to have been in operation for three years (20 U.S.C. 2302(52)(E)). Should a new entity that aspires to be a “tribally controlled postsecondary career and technical institution” emerge and begin operations in the next year or later, it would not be eligible to apply to TCPTIP until FY 2028 at the earliest.</P>

                    ection 117 of Perkins V authorizes the Secretary to make grants to Tribally Controlled Postsecondary Career and Technical Institutions that do not receive Federal support under title I of the Tribally Controlled Colleges and Universities Assistance Act of 1978 (25 U.S.C. 1801 
                    <E T="03">et seq.</E>
                    ) or the Navajo Community College Act (Pub. L. 92-189, as amended) for career and technical education programs for Native American students and for the institutional support costs of the grant.

                <P>
                    Current TCPCTIP grantees, selected based on the TCPCTIP notice inviting applications published in the 
                    <E T="04">Federal Register</E>
                     (84 FR 29854) on June 25, 2019 (NIA), operate career and technical education programs for Native American students as authorized by section 117 of Perkins V (20 U.S.C. 2327). The budget and project period for the two TCPCTIP grantees is scheduled to end with funds awarded in FY 2023.
                </P>
                <P>
                    For these projects, the Secretary waives the requirements of 
                    <E T="03">34 CFR 75.250</E>
                     and
                    <E T="03"> 75.261(c)(2)</E>
                    , which limit project periods to 60 months and restrict project period extensions that involve the obligation of additional Federal funds. The Secretary makes these changes because section 117(i) of Perkins V authorizes appropriations for activities under section 117 of the Act, through FY 2024 (20 U.S.C. 2327(i)). The Secretary also extends the project period for the two current TCPCTIP grantees (Perkins V, section 117(a); 20 U.S.C. 2327(a)) through FY 2027, if Congress continues to appropriate funds under the existing program authority. The waiver and extension enables the two current TCPCTIP grantees to request and continue to receive Federal funds beyond the 60-month limitation set by 
                    <E T="03">34 CFR 75.250.</E>
                </P>
                <P>Moreover, with the waiver and extension, the Department will not announce a new competition or make new awards until FY 2027, if Congress continues to authorize and appropriate funds under the existing program authority. Instead, current TCPCTIP projects funded under the NIA could be continued at least through the FY 2027 budget and project period if Congress continues to appropriate funds for TCPCTIP under the existing program authority.</P>
                <P>We believe that the waiver and extension is in the public interest, given that NTU and UTTC are the only two eligible entities for the TCPCTIP program, and those entities are the current grantees. Running another competition in which only the same very limited number of entities will be eligible to receive awards is not an effective use of Department and grantee resources. Further, allowing these grantees to continue their projects will provide continuity in the current projects and resources for the current beneficiaries of the grantees' programs.</P>
                <P>
                    We will base our decisions regarding annual continuation awards on the program narratives, budgets, budget narratives, and program performance reports, submitted by current grantees, and the requirements in 
                    <E T="03">34 CFR 75.253.</E>
                     Any activities to be carried out during the year or years of continuation awards must be consistent with, or be a logical extension of, the scope, goals, and objectives of each grantee's application, as approved following the 2019 TCPCTIP competition. We will award continuation grants based on information provided to us by each grantee, indicating that it is making substantial progress performing its TCPCTIP grant activities.

                    For areas designated nonattainment for one or more of the National Ambient Air Quality Standards (NAAQS), the applicable SIP must include preconstruction review and permitting requirements for new or modified major stationary sources of such nonattainment pollutant(s) under part D of title I of the Act, commonly referred 
                    <PRTPAGE P="42809"/>
                    to as Nonattainment New Source Review (NNSR). The rule listed in Table 1 contains the SLOCAPCD's NNSR permit program applicable to new and modified major sources located in the areas within the District that are designated nonattainment for the NAAQS. 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 did not receive any comments.</P>
                <HD SOURCE="HD1">III. EPA Action</HD>
                <P>
                    No comments were submitted on our proposal. We continue to find that Rule 224 satisfies the relevant requirements for a CAA NNSR program for ozone,
                    <SU>2</SU>
                    <FTREF/>
                     as well as the associated visibility requirements for sources subject to review under such a program in accordance with 40 CFR 51.307. Therefore, as authorized in section 110(k)(3) of the Act, the EPA is approving the submitted rule.
                </P>

                    <P>
                        <SU>2</SU>
                         As discussed in our proposed action, we determined that Rule 224 satisfies the NNSR program requirements applicable to nonattainment areas classified as Marginal for ozone, and that the submittal addressed the NNSR requirements both the 2008 and 2015 ozone NAAQS. 88 FR 90138, 90139.

                </FTNT>
                <P>This action incorporates the submitted rule into the California SIP. In conjunction with the EPA's SIP approval of the District's visibility program for sources subject to the NNSR program, this action also revises the scope of the visibility Federal Implementation Plan (FIP) at 40 CFR 52.281 for California so that this FIP no longer applies to sources located in the SLOCAPCD nonattainment areas that are subject to the District's visibility program.</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 incorporating by reference San Luis Obispo County Air Pollution Control District Rule 224, “Federal Requirements for New and Modified Major Sources in Non-Attainment Areas,” adopted on January 26, 2022, as described in Section I of this preamble, which regulates the District's issuance of permits for stationary sources under part D of title I of the CAA.

                <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.C. 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 proposes to approve 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 District 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 goals of E.O. 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 July 15, 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>

                        ) Reasonably Available Control Technology (RACT) for the Facility sources identified as four power boilers, a wood waste boiler, and four recovery boilers. This action is being taken in accordance with the requirements of the Clean Air Act (CAA) for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposed to approve this rule on January 19, 2024, and received three comments all of which were in favor of the rulemaking.

                    A SSSIP revision was submitted to the EPA by the State of New York on May 24, 2022, for Finch Paper LLC, located at 1 Glen Street, Glens Falls, New York (the Facility), and it replaces and withdraws the SSSIP that was submitted by the State on September 16, 2008. On January 19, 2024, the EPA published a notice of proposed rulemaking that proposed to approve a SSSIP revision to addresses NO
                    <E T="52">X</E>
                     RACT emission limits for the Facility's nine boilers. 
                    <E T="03">See</E>
                     89 FR 3620. Specifically, the notice of proposed rulemaking addressed the following: (1) Source-specific emission limits and RACT control options for four large power boilers where the presumptive NO
                    <E T="52">X</E>
                     limit is not technologically and economically feasible; (2) a case-by-case NO
                    <E T="52">X</E>
                     emission limit for the wood waste boiler's biomass fuel; and (3) NO
                    <E T="52">X</E>
                     emission limits for four recovery boilers that are not covered by other New York RACT regulations, and therefore must follow 6 NYCRR part 212 as a process operation.
                </P>
                <P>
                    The EPA is determining through this final action that the NO
                    <E T="52">X</E>
                     RACT emission limits included in the May 24, 2022, SSSIP revision are demonstrated to be RACT for the power boilers, wood waste boiler and the recovery boilers. The boilers have the lowest emission limits with the application of control technology that are reasonably available given the technological and economic feasibility considerations. Furthermore, the NO
                    <E T="52">X</E>
                     RACT emission limits for the boilers comply with the New York State regulations, 6 NYCRR part 227, “Stationary Combustion Installations,” subpart 227-2, “Reasonably Available Control Technology for Major Facilities of Oxides of Nitrogen,” and 6 NYCRR part 212, “Process Operations,” subpart 212-3, “Reasonably Available Control Technology for Major Facilities”, and are contained in the Facility's title V operating permit, 5-5205-00005/00059. The permit was issued by the State on December 20, 2021, modified on January 
                    <PRTPAGE P="42811"/>

                    The specific details for how the NO
                    <E T="52">X</E>
                     emission limits comprise RACT for the power boilers, wood waste boiler and the recovery boilers, and the rationale for the EPA's approval action, are explained in the EPA's notice of proposed rulemaking and are not restated in this final action. For this detailed information, the reader is referred to the EPA's notice of proposed rulemaking. 89 FR 3620 (January 19, 2024).

                <HD SOURCE="HD1">II. Environmental Justice Considerations</HD>
                <P>The CAA and applicable implementing regulations neither prohibit nor require an environmental justice evaluation and so the State of New York did not evaluate environmental justice considerations as part of its SSSIP submittal. The EPA performed an environmental justice analysis for the purpose of transparency about this rulemaking to the public and the analysis is not provided for the basis of this action.</P>
                <P>
                    The EPA created a Community Report (Report) using its EJ Screen, Version 2.2, representing a 1-mile ring centered at the Facility. We analyze both EJ Indexes and Supplemental Indexes because they offer different perspectives on community level vulnerability based on different factors. We also use the National percentile for the Report results and not the State percentile since this SSSIP action is a Federal action. Lastly, the EPA focused on any environmental index result that is 80 percentile or greater because environmental indexes at this level are relatively high compared to the United States population. The Report shows the Facility ranked greater than 80th percentile for National Supplemental Indexes, as follows: 83rd percentile for Superfund proximity; and 81st percentile for being located near a facility regulated under the Risk Management Program (extremely hazardous substances). The Report,

                <P>
                    The EPA received three public comments during the 60-day public comment period of the EPA's proposed approval of New York's SIP revision. All commenters are in support of the action. The specific comments may be viewed under Docket ID Number EPA-R02-OAR-2022-0714 on the

                <P>
                    Regarding one commenter, the EPA appreciates the commenter's support of the proposed action. Regarding the commenter's point about the EJ Index, the EPA notes that EJ Screen has two indexes, the EJ Index and the Supplemental Index. Although it is correct to say that Finch Paper shows no EJ Index above 80th percentile, the EPA notes that Finch Paper shows above 80th percentile for Supplemental Indexes. The Supplemental Index includes data on low-income, linguistically isolated, high school education, unemployment, and low life expectancy. Please refer to the EJ Screen Report that is contained in the EPA docket assigned to this 
                    <E T="04">Federal Register</E>
                     document. Also, the Facility is regulated because of the RACT regulations, not because of EJ concerns. Lastly, this action addresses NO
                    <E T="52">X</E>
                     RACT variance for the boilers—the SSSIP revision does not involve rerouting the smoke of boilers into separate smoke stacks.
                </P>
                <P>Regarding another commenter, the EPA appreciates the commenter's support of the proposed action, and notes that the cap-and-trade program is beyond the scope of this action.</P>

                <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.C. 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 
                    <PRTPAGE P="42812"/>
                    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 it 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, Feb. 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.” resulting from the negative environmental consequences of industrial, governmental, and commercial operations or programs and policies.”</P>
                <P>The New York State Department of Environmental Conservation did not evaluate environmental justice considerations as part of its SSSIP submittal; the CAA and applicable implementing regulations neither prohibit nor require such an evaluation. The EPA performed an environmental justice analysis, as is described above in the section titled, “Environmental Justice Considerations.” The analysis was done for the purpose of providing additional context and information about this rulemaking to the public, not as a basis of the action. In addition, there is no information in the record upon which this decision is based inconsistent with the stated goal of E.O. 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 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 July 15, 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>On March 1, 2024 (89 FR 15096), EPA published a notice of proposed rulemaking (NPRM) proposing approval of revisions to the Delaware SIP. The revision will incorporate into the Delaware SIP amendments to subsections 12.3.2 and 12.4.2 of Title 7 Delaware Administrative Code 1102 (7 DE Admin Code 1102), Permits. The formal SIP revision was submitted by Delaware Department of Natural Resources and Environmental Control (DNREC) on behalf of the State of Delaware on November 10, 2022. Delaware amended 7 DE Admin Code 1102 (DE 1102) to update the public notice requirements for permits covered by the regulation to be consistent with certain provisions of the October 18, 2016 rule regulatory revisions “Revisions to Public Notice Provisions in Clean Air Act Permitting Programs,” (81 FR 71613, October 18, 2016) and the implementing regulations codified in the Code of Federal Regulations (CFR) at 40 CFR 70.7(h)(2).</P>
                <HD SOURCE="HD1">II. Summary of SIP Revision and EPA Analysis</HD>
                <P>
                    Delaware's November 10, 2022 SIP submission reflects amendments made to its public notice requirements in DE 1102 that are consistent with those in the EPA October 18, 2016 rule's public notice requirements. While DE 1102 applies to some permits that are not covered by EPA's October 18, 2016 rule (such as minor sources), some of the permits covered by DE 1102 are addressed by the October 18, 2016 rule, such as major source operating permits (which are covered under DE 1130 
                    <SU>1</SU>
                    <FTREF/>
                    ).

                        <SU>1</SU>
                         Delaware had previously revised the public notice operating requirements of its title V operating permit regulations, 7 DE Admin. Code 1130 (DE 1130). DE 1102 also applies to title V sources covered by 1130 as well as other sources, such as minor sources not covered by DE 1130. The effect of these changes is to make all sources covered by DE 1102 and 1130 subject to identical state public notice requirements. The changes to DE 1130 have not been submitted to EPA for approval and are not part of this rule.
                    </P>
                </FTNT>
                <P>Specifically, Delaware's submittal consists of changes to subsections 12.3.2 and 12.4.2 of DE 1102. These subsections have been amended to require that each public notice include: (1) the name, address, and telephone number of a person (or an email or website address) of DNREC Staff from whom interested persons may obtain additional information; and (2) the time and place of any hearing that may be held, including a statement of procedures to request a hearing (unless a hearing has already been scheduled). The updated regulatory language in DE 1102 (and DE 1130) is consistent with that of EPA's October 18, 2016 rule and Federal regulations regarding public notice requirements for major source permits (81 FR 71613 and 40 CFR 70.7(h)(2)).</P>
                <P>The rationale for EPA's action is further explained in the NPRM, and will not be restated here.</P>
                <HD SOURCE="HD1">III. EPA's Response to Comments Received</HD>
                <P>EPA received one public comment for the NPRM. That comment is not relevant to this action. EPA therefore offers no response to the comment.</P>
                <HD SOURCE="HD1">IV. Final Action</HD>
                <P>EPA is approving revision to subsections 12.3.2 and 12.4.2 of 7 DE Admin Code 1102, Permits as a revision to the Delaware SIP.</P>
                <HD SOURCE="HD1">V. Incorporation by Reference</HD>
                <P>
                    In this document, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of the amendments to subsections 12.3.2 and 12.4.2 of DE 1102, as discussed in sections I and II of this preamble. EPA has made, and will continue to make, these materials generally available through 
                    <E T="03">www.regulations.gov</E>
                     and at the EPA Region III Office (please contact the person identified in the

                     section of this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the SIP, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rule of EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.

                <P>Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve State choices, provided that they meet the criteria of the CAA. 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 13563 (76 FR 3821, January 21, 2011);</P>
                <P>
                    • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 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 an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);</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 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 
                    <PRTPAGE P="42814"/>
                    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. 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. 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 DNREC 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. EPA did not perform an EJ analysis and did not consider EJ in this final rule. Due to the nature of this action being taken here, where EPA is approving revisions of the State regulations to be consistent with notice and comment provisions previously established by EPA, this final rule is expected to have a neutral to positive impact on the air quality of the affected area.</P>

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.

                <HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD>
                <P>The Gulf reef fish fishery, which includes red snapper, is managed under the Fishery Management Plan for the Reef Fish Resources of the Gulf of Mexico (FMP). The FMP was prepared by the Gulf of Mexico Fishery Management Council and is implemented by NMFS under the authority of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act) by regulations at 50 CFR part 622.</P>
                <P>The final rule implementing Amendment 40 to the FMP established two components within the recreational sector fishing for Gulf red snapper: the private angling component and the Federal for-hire component (80 FR 22422, April 22, 2015). Amendment 40 also allocated the red snapper recreational annual catch limit (ACL; recreational quota) between the components and established separate seasonal closures for the two components. The Federal for-hire component's red snapper annual catch target (ACT) is 9 percent below the for-hire component quota (87 FR 74014, December 2, 2022; 50 CFR 622.41(q)(2)(iii)(B)).</P>
                <P>The red snapper for-hire component seasonal closure is projected from the component's ACT. Projecting the for-hire component's seasonal closure using the ACT reduces the likelihood of the harvest exceeding the component quota and the total recreational quota. The Federal for-hire component ACT for red snapper in the Gulf EEZ is 3,076,322 pounds (1,395,396 kilograms), round weight (50 CFR 622.41(q)(2)(iii)(B)).</P>
                <P>
                    The 2024 Federal Gulf red snapper for-hire fishing season has been determined to be 88 days based on NMFS' projection of the date landings are expected to reach the Federal for-hire component ACT. NMFS determined that 88 days is likely to constrain harvest to the for-hire component ACT based on catch rates from the 2023 fishing year. For details about the calculation of the projection for 2024, see 
                    <E T="03">https://www.fisheries.noaa.gov/southeast/sustainable-fisheries/gulf-mexico-recreational-red-snapper-management.</E>
                     Therefore, the 2024 recreational season for the Federal for-hire component will begin at 12:01 a.m., local time, on June 1, 2024, and close at 12:01 a.m., local time, on August 28, 2024.
                </P>
                <P>
                    On and after the effective date of the Federal for-hire component closure, the bag and possession limits for red snapper for Federal for-hire vessels are zero. When the Federal for-hire component is closed, these bag and possession limits apply in the Gulf on board a vessel for which a valid Federal for-hire permit for Gulf reef fish has been issued, without regard to where such species were harvested, 
                    <E T="03">i.e.,</E>
                     in state or Federal waters. In addition, a person aboard a vessel that has been issued a charter vessel/headboat permit for Gulf reef fish any time during the fishing year may not harvest or possess red snapper in or from the Gulf EEZ when the Federal charter vessel/headboat component is closed.

                <P>NMFS issues this action pursuant to section 305(d) of the Magnuson-Stevens Act. This action is taken under 50 CFR 622.41(q)(2)(i) and (ii), which was issued pursuant to section 304(b) of the Magnuson-Stevens Act, and is exempt from review under Executive Order 12866.</P>
                <P>Pursuant to 5 U.S.C. 553(b)(B), there is good cause to waive prior notice and an opportunity for public comment on this action, as notice and comment is unnecessary and contrary to the public interest. Such procedures are unnecessary because the rule implementing the recreational red snapper quotas and ACTs, and the rule implementing the requirement to close the for-hire component when its ACT is projected to be reached have already been subject to notice and comment, and all that remains is to notify the public of the closure. Such procedures are contrary to the public interest because many for-hire operations book trips for clients in advance and require as much notice as NMFS is able to provide to adjust their business plans to account for the fishing season.</P>

                <HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD>
                <P>SBA proposes to make changes to the process by which an application for certification is reviewed by SBA in order to implement a statutory amendment from the National Defense Authorization Act for Fiscal Year 2022 regarding the effects of a status determination on a small business concern. SBA also proposes to remove outdated references to the U.S. Department of Veterans Affairs Center for Verification and Evaluation, instead referring to SBA's Veteran Small Business Certification Program. The rule would also provide additional definitions of terms used in the regulations, attempt to provide consistency across the regulations used in SBA's other government contracting programs, and define who is authorized to represent a firm when validating or signing certification pages during the certification process.</P>
                <HD SOURCE="HD1">Section-by-Section Analysis</HD>
                <HD SOURCE="HD2">Sections 124.106(a), 127.202(c), and 128.203(i)</HD>
                <P>Sections 124.106(a) (for the 8(a) Business Development (BD) program), 127.202(c) (for the women-owned small business (WOSB program), and 128.203(i) (for the veteran small business certification (VetCert) program) address limitations on outside employment that can affect a business concern's eligibility for participation in the 8(a) BD, WOSB, and VetCert programs based on a qualifying individual's lack of control. Basically, each of these provisions generally requires the qualifying individual to devote fulltime or the number of hours of normal operation to the business. Each also requires the business concern to demonstrate how a qualifying individual does in fact control the day-to-day operations of the business concern if the qualifying individual does devotes fewer hours to the business than its normal hours of operation. The language of the three provisions, however, is not identical. This has led to questions as to whether SBA intended different application of the control requirements for different programs. In order to clear up any confusion, this rule proposes to change the wording of the three provisions to make them identical to ensure that the control requirement is consistently applied. Basically, the rule would align the language of the restrictions in 8(a) BD and WOSB programs to the current restriction in the VetCert Program.</P>
                <HD SOURCE="HD2">Section 127.102</HD>
                <P>Section 127.102 sets out the definitions for the Women-Owned Small Business (WOSB) Federal Contract Program. This rule first proposes to add a definition for the term “Applicant” as a definition was not included in the previous version of the regulations and appears in the regulations of SBA's other government contracting programs. SBA believes that including this definition will provide consistency in the rules that apply to its various certification programs and make clear that a concern applying for certification in the WOSB Program is an “Applicant.” </P>
                <P>The proposed rule would amend the current definition of the term “System for Award Management (SAM) (or any successor system).” SBA believes that the definition is outdated and should match the definition that is used in the FAR for consistency purposes.</P>
                <P>The proposed rule would also remove the definition for “WOSB Program Repository” as this definition refers to the old repository system that is no longer in use. SBA believes that removing this definition, which is not used elsewhere in 13 CFR part 127, will alleviate any confusion.</P>
                <P>
                    Lastly, the proposed rule would amend the current definition of “Interested party,” limiting it to certified WOSB concerns or concerns that have a pending application for WOSB certification, either at SBA or a third-party certifier, that submit an offer for a specific Economically Disadvantaged Women-Owned Small Business (EDWOSB) or WOSB requirement, rather than any concern 
                    <PRTPAGE P="42817"/>
                    who submits an offer for a specific EDWOSB or WOSB requirement. SBA believes that only certified WOSBs and EDWOSBs or concerns pending WOSB certification should be able to submit a protest against an apparent successful offeror's EDWOSB or WOSB status. It is not uncommon for an incumbent contractor to file a bid or size/status protest in order for its performance to be extended pending the resolution of the protest. SBA does not want to encourage firms that are not certified WOSBs or certified EDWOSBs to submit offers merely to be able to file a status protest that could prolong their performance under a preceding contract. Such firms have no chance to be awarded a WOSB/EDWOSB contract, and such protests may be nothing more than delay tactics. Only firms that are capable of winning the WOSB set-aside contract or order should be able to protest the WOSB status of an apparent successful offeror.
                </P>
                <HD SOURCE="HD2">Section 127.202</HD>
                <P>Current § 127.202 generally requires that a woman devote sufficient time to the business with a rebuttable presumption that the business is not a WOSB if a woman devotes fewer hours to the business than its normal hours of operation. Where the presumption applies, the woman must provide evidence to SBA that she has ultimate managerial and supervisory control over both the long-term decision making and day-to-day management and administration of the business. This rule proposes to align this language to the current restriction in the Veteran Small Business Certification Program. The business still will be generally required to have the qualified woman that controls the concern devote the woman's full time to the business during the business's normal hours of operation. The business may, however, demonstrate to SBA that the woman has ultimate managerial and supervisory control over both the long-term decision making and day-to-day management of the business.</P>
                <HD SOURCE="HD2">Section 127.300</HD>
                <P>The proposed rule would amend the outdated references in § 127.300(a)(2) and (b)(3) to certifications made by the U.S. Department of Veterans Affairs (VA) Center for Verification and Evaluation. Instead, the regulation would refer to SBA's Veteran Small Business Certification Program. SBA believes this change would resolve any confusion caused by reference to the VA's Verification Program, which no longer certifies veteran-owned or service-disabled veteran-owned small business concerns following its transfer to SBA pursuant to section 862 of the National Defense Authorization Act for Fiscal Year 2021.</P>
                <P>The proposed rule would also amend § 127.300(c) by referring to SAM, in addition to the Dynamic Small Business Search (DSBS) system. This change would recognize that a concern that is a qualified WOSB or EDWOSB will be designated as such in both SAM and the DSBS system.</P>
                <HD SOURCE="HD2">Section 127.303</HD>
                <P>The proposed rule would add a new paragraph and reorganize § 127.303(a)(1) to provide that a concern certified as a veteran-owned or service-disabled veteran-owned small business for the Veteran Small Business Certification Program and owned and controlled by one or more women may use documentation of its Veteran-Owned Small Business Concern (VOSB) or Service-Disabled Veteran-Owned Small Business Concern (SDVOSB) certification or more recent recertification in support of its application for WOSB certification. The proposed rule would further provide that if the concern is also seeking EDWOSB certification, it must submit documentation that demonstrates it is owned and controlled by one or more women who are economically disadvantaged in accordance with § 127.203. This change would recognize a concern's ability to use documentation from SBA's other certification program in support of its application for WOSB certification and refer to the current veteran-owned and service-disabled veteran-owned certification program.</P>
                <HD SOURCE="HD2">Section 127.305</HD>
                <P>The proposed rule would incorporate the same language used in § 124.207 for purposes of applying to the 8(a) Business Development (BD) Program. Section 124.207 provides that a concern that has applied to the 8(a) BD program and has been declined three times within 18 months of the date of the first final Agency decision finding the concern ineligible cannot submit a new application for admission to the program until 12 months from the date of the third final Agency decision to decline. SBA seeks to provide consistency among its various certification programs and believes that an applicant that has applied three times within a relatively short timeframe and has not corrected its deficiencies should be required to wait 12 months before applying again. SBA wants to encourage concerns to submit accurate applications in the first instance and to fully respond to all deficiencies noted in its decline decisions.</P>
                <HD SOURCE="HD2">Section 127.356(c)</HD>
                <P>
                    The proposed rule would revise § 127.356(c) to provide consistency between § 127.356(c) and § 127.356(a) and (b). Currently, § 127.356(c) states that an approved third-party certifier must ensure that all of a concern's documents are uploaded in 
                    <E T="03">https://certify.sba.gov</E>
                     or any successor system. SBA believes that is inconsistent with SBA's intent that it is the responsibility of the concern, not the SBA-approved third-party certifier, to ensure that all its documents are uploaded. Section 127.356(a) and (b) require the applicant concern to apply directly with a third-party certifier and register in SAM. Consistent with paragraphs (a) and (b), SBA believes that it is the responsibility of the applicant concern, and not the third-party certifier, to ensure that all documents necessary to determine its eligibility for certification by an approved certifier are uploaded with its application. SBA believes this uniformity within the section will lead to less confusion about whose duty it is to make sure documents have been made available to SBA when a third-party certifier is involved. Furthermore, a system has not yet been put in place for a third-party certifier to upload the documents on behalf of the concern.
                </P>
                <HD SOURCE="HD2">Section 127.504(a)</HD>
                <P>Section 127.504 permits a concern that has submitted a complete application for WOSB or EDWOSB certification to SBA or a third-party certifier and has not received a negative determination regarding that application to submit an offer for a competitive WOSB or EDWOSB award. The proposed rule would define “pending application,” as this term is not currently defined in this section or elsewhere in the WOSB regulations. SBA believes providing this definition will lead to less confusion amongst concerns and contracting officers who have been unsure when an application is pending and believed an application to be pending at the point of application. This change will support the acquisition process for WOSB and EDWOSB set-asides.</P>
                <HD SOURCE="HD2">Section 127.604(f)</HD>
                <P>
                    The proposed rule would add the language describing the effects of a status determination on a concern and the obligation of a concern to update the System for Award Management (or any successor system) within two business days of a final determination. This change would be made to implement a 
                    <PRTPAGE P="42818"/>
                    statutory amendment of the National Defense Authorization Act of Fiscal Year 2022, which amended section 863 of the Small Business Act, to provide such language in the status determination of a concern.
                </P>
                <HD SOURCE="HD2">Section 127.701</HD>
                <P>The proposed rule would remove this section entirely as it contains outdated language regarding the previous WOSB program and system whereby a concern certified its WOSB or EDWOSB status on SAM in relation with specific eligibility requirements. This section, in its entirety, is no longer necessary, as 13 CFR 127.304(f) and other WOSB program regulations specify that SBA will update DSBS and SAM to indicate that a concern has been certified by SBA as a WOSB and/or EDWOSB.</P>
                <HD SOURCE="HD1">Request for Comments</HD>
                <P>SBA invites all interested parties to participate in this rulemaking by submitting written data, views, comments, and arguments on all aspects of this proposed rule. Comments that will provide the most assistance to SBA in implementing these changes will reference a specific portion of the proposed rule, explain the reason for any recommended change, and include data, information, or authority that support such recommended change. Comments submitted in a manner other than the methods listed above will not be considered comments on the proposed rule and may not receive a response from SBA.</P>
                <HD SOURCE="HD1">Compliance With Executive Orders 12866, 12988, 13132, 13563, and the Paperwork Reduction Act (44 U.S.C. Ch. 35), the Regulatory Flexibility Act (5 U.S.C. 601-612)</HD>
                <HD SOURCE="HD2">Executive Order 12866</HD>
                <P>The Office of Management and Budget has determined that this proposed rule is not a “significant regulatory action” under Executive Order 12866. This proposed rule would amend the WOSB regulations to provide uniformity amongst SBA's government contracting programs and to clarify certain regulations that have been misunderstood by concerns and contract officers. As such, the proposed rule has no effect on the amount or dollar value of any Federal contract requirements or of any financial assistance provided through SBA. Therefore, the proposed rule is not likely to have an annual economic effect of $200 million or more, result in a major increase in costs or prices, or have a significant adverse effect on competition or the United States economy. In addition, this proposed rule does not create a serious inconsistency or otherwise interfere with an action taken or planned by another agency, materially alter the budgetary impact of entitlements, grants, user fees, loan programs, or the rights and obligations of such recipients, nor raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive order.</P>
                <HD SOURCE="HD2">Executive Order 13563</HD>
                <P>Executive Order 13563, Improving Regulation and Regulatory Review (January 18, 2011), requires agencies to adopt regulations through a process that involves public participation, and to the extent feasible, base regulations on the open exchange of information and perspectives from affected stakeholders and the public as a whole. SBA has developed this proposed rule in a manner consistent with these requirements, and the public will have the opportunity to provide comments following the publication of this proposed rule.</P>
                <HD SOURCE="HD2">Executive Order 12988</HD>
                <P>This action meets applicable standards set forth in section 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden. The action does not have retroactive or preemptive effect.</P>
                <HD SOURCE="HD2">Executive Order 13132</HD>
                <P>This proposed rule does not have Federalism implications as defined in Executive Order 13132. It will not have substantial direct effects on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in the Executive order. As such, it does not warrant the preparation of a Federalism Assessment.</P>
                <HD SOURCE="HD2">Paperwork Reduction Act</HD>
                <P>The SBA has determined that this proposed rule does not impose additional reporting or recordkeeping requirements under the Paperwork Reduction Act, 44 U.S.C. chapter 35.</P>
                <HD SOURCE="HD2">Regulatory Flexibility Act</HD>
                <P>The Regulatory Flexibility Act of 1980, as amended (RFA), 5 U.S.C. 601-612, requires Federal agencies to prepare an initial regulatory flexibility analysis (IRFA) to consider the potential impact of the regulations on small entities. Small entities include small businesses, small not-for-profit organizations, and small governmental jurisdictions. Section 605 of the RFA allows an agency to certify a rule, in lieu of preparing an IRFA, if the rulemaking is not expected to have a significant economic impact on a substantial number of small entities.</P>
                <P>This proposed rule would revise the WOSB regulations to update definitions and adopt similar language to that used in SBA's other government contracting program regulations. Specifically, the proposed rule would amend the length of time in which a firm that has been declined three times must wait before reapplying to the WOSB Program and remove reference to the 15-calendar day timeframe in which SBA will notify an applicant for certification to the WOSB Program that their application is either complete or incomplete. While SBA does not anticipate that this proposed rule would have a significant economic impact on any small business, we do welcome comments from any small business setting out how and to what degree this proposed rule would affect it economically. Therefore, the Administrator of SBA certifies under 5 U.S.C. 605(b) that this proposed rule would not have a significant economic impact on a substantial number of small entities.</P>

                        The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC225LP helicopters. This proposed AD was prompted by a report of water in the oil of a main gearbox (MGB). This AD requires replacing certain main rotor (M/R) mast upper stops assembly screws. This proposed AD would also require inspecting certain M/R mast 
                        <PRTPAGE P="42821"/>
                        cover plates and accomplishing MGB oil analyses and, depending on the results, replacing the M/R mast cover plate, accomplishing an additional inspection, or replacing the MGB. This proposed AD would also prohibit installing certain M/R mast upper stops assembly screws, M/R masts with an affected M/R mast upper stops assembly screw installed, or used M/R mast cover plates on any helicopter. Lastly, this proposed AD would prohibit installing affected M/R masts unless the inspections are done. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

                <P>EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022-0104, dated June 9, 2022 (EASA AD 2022-0104), to correct an unsafe condition on Airbus Helicopters Model EC 225 LP helicopters.</P>
                <P>This proposed AD was prompted by a report of water in the oil of an MGB, due to an incorrect installation of the upper M/R mast cover plate. According to Airbus Helicopters, a detailed inspection of the MGB showed corrosion on the M/R mast and inside the MGB. The upper M/R mast cover plate was deformed. Also, according to Airbus Helicopters, a different M/R mast had damaged upper stop screws installed, also due to an incorrect installation. The FAA is issuing this proposed AD to prevent water in the MGB oil. The unsafe condition, if not addressed, could result in corrosion of the M/R mast and inside the MGB, degradation of the MGB, degradation of the upper stops assembly, failure of a critical part, and subsequent loss of control of the helicopter.</P>
                <P>
                    You may examine EASA AD 2022-0104 in the AD docket at 
                    <E T="03">regulations.gov</E>

                <P>EASA AD 2022-0104 requires replacing each M/R mast upper stops assembly screw, except those marked with “BC” on the screw head. For certain helicopters, EASA AD 2022-0104 requires inspecting a certain part-numbered M/R mast cover plate and depending on the results, replacing the cover plate and accomplishing an additional inspection. For those same certain helicopters, EASA AD 2022-0104 also requires accomplishing MGB oil analyses and, depending on the results, accomplishing an additional inspection. Depending on the results of the additional inspection following the M/R mast cover plate inspection or MGB oil analyses, EASA AD 2022-0104 requires replacing the MGB. As an option, EASA AD 2022-0104 allows replacing the MGB as an acceptable alternative method to comply with the required MGB oil sample analyses.</P>
                <P>
                    Lastly, EASA AD 2022-0104 prohibits installing M/R mast upper stops assembly screws—except those marked 
                    <PRTPAGE P="42822"/>
                    with “BC” on the screw head, M/R masts with an affected M/R mast upper stops assembly screw installed, and used M/R mast cover plates on any helicopter. EASA AD 2022-0104 also prohibits installing an affected M/R mast unless its required inspections are done.

This service information specifies procedures for inspecting the M/R mast upper stops assembly screws to determine if they're marked with “BC” on the screw head and depending on the results, replacing those screws one by one. This service information also specifies procedures for checking the flatness of the M/R mast cover plate and, depending on the results, removing and discarding that cover plate, installing a flat cover plate, draining the MGB, writing to Airbus Helicopters to do a detailed MGB inspection, and removing the M/R mast. Depending on the detailed MGB inspection results, this service information specifies filling the MGB with oil and installing the M/R mast; or replacing the MGB with an airworthy MGB, sending the removed MGB to an approved D-level center for repair, and installing the M/R mast.</P>
                <P>This service information also specifies procedures for collecting an MGB oil sample and sending the sample to an Airbus Helicopters approved laboratory for water content analysis.

Depending on the detailed MGB inspection results, this service information specifies filling the MGB with oil and installing the M/R mast; or replacing the MGB with an airworthy MGB, sending the removed MGB to an approved D-level center for repair, and installing the M/R mast.</P>
                <HD SOURCE="HD1">FAA's Determination</HD>
                <P>These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design.</P>
                <HD SOURCE="HD1">Proposed AD Requirements in This NPRM</HD>
                <P>This proposed AD would require accomplishing the actions specified in EASA AD 2022-0104, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under “Differences Between this Proposed AD and the EASA 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 2022-0104 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022-0104 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 2022-0104 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 2022-0104. Service information referenced in EASA AD 2022-0104 for compliance will be available at 
                    <E T="03">regulations.gov</E>
                     under Docket No. FAA-2024-1297 after the FAA final rule is published.
                </P>
                <HD SOURCE="HD1">Differences Between This Proposed AD and the EASA AD</HD>
                <P>For certain helicopters, EASA AD 2022-0104 specifies sending oil samples to an Airbus Helicopters approved laboratory for an analysis of the water content, whereas this proposed AD would require sending the main gearbox oil sample for water content analysis. Additionally, for those helicopters, EASA AD 2022-0104 specifies taking and analyzing the second MGB oil sample within 110 FH or 3 months after the initial oil sample, whereas this proposed AD would require collecting the second main gearbox oil sample and sending it for water content analysis within 110 hours time-in-service or 3 months after accomplishing the initial instance of those actions, whichever occurs later. Depending on the results of the cover plate inspection or an oil sample analysis, EASA AD 2022-0104 specifies contacting Airbus Helicopters to request to accomplish a detailed inspection, which shall be accomplished by authorized Airbus Helicopters staff and the Airbus Helicopters qualified staff identify any discrepancies, whereas this proposed AD would require a detailed inspection, which must define what is considered a discrepancy and be done in accordance with a method approved by the FAA, EASA, or Airbus Helicopters' EASA Design Organization Approval.</P>
                <HD SOURCE="HD1">Costs of Compliance</HD>
                <P>The FAA estimates that this AD, if adopted as proposed, would affect 32 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this proposed AD.</P>
                <P>Replacing the M/R mast upper stops assembly screws (up to 10 screws) would take up to approximately 0.5 work-hour and parts would cost up to approximately $250 (for 10 screws) for an estimated cost of up to $293 per helicopter and $9,376 for the U.S. fleet.</P>
                <P>For certain helicopters, inspecting the M/R mast cover plate would take approximately 0.5 work-hour for an estimated cost of $43 per helicopter and up to $1,376 for the U.S. fleet. Collecting an MGB oil sample and sending the MGB oil sample for water content analysis, which is considered a reporting requirement in this proposed AD, would take approximately 1.5 work-hours (0.5 work-hour for collecting and 1 work-hour for sending) for an estimated cost of $128 per helicopter and up to $4,096 for the U.S. fleet, per instance.</P>
                <P>
                    If required, replacing the M/R mast cover plate would take approximately 2 work-hours and parts would cost approximately $276 for an estimated cost of $446 per helicopter. The detailed inspection that may be needed could vary significantly from helicopter to helicopter. The FAA has no data to determine the costs to accomplish the detailed inspection or the number of helicopters that may need it. Replacing an MGB would take approximately 40 work-hours and parts would cost approximately $998,595 (overhauled) for an estimated cost of $1,001,995 per helicopter.

                    <HD SOURCE="HD1"> (e) Unsafe Condition</HD>
                    <P>This AD was prompted by a report of water in the oil of a main gearbox (MGB), due to an incorrect installation of the upper main rotor mast cover plate. The FAA is issuing this AD to prevent water in the MGB oil. The unsafe condition, if not addressed, could result in corrosion of the main rotor mast and inside the MGB, degradation of the MGB, degradation of the upper stops assembly, failure of a critical part, and subsequent loss of control of the helicopter.</P>

                <P>
                    The FAA is planning to decommission the VOR portion of the Beckley, WV, VOR/DME in February 2025. The Beckley VOR is one of the candidate VORs identified for discontinuance by the FAA's VOR MON program and listed in the Final policy statement notice, “Provision of Navigation Services for the Next Generation Air Transportation System (NextGen) Transition to Performance-Based Navigation (PBN) (Plan for Establishing a VOR Minimum Operational Network),” published in the 
                    <E T="04">Federal Register</E>
                     on July 26, 2016 (81 FR 48694), Docket No. FAA-2011-1082.
                </P>
                <P>Although the VOR portion of the Beckley VOR/DME is planned for decommissioning, the co-located Distance Measuring Equipment (DME) is being retained to continue supporting current and future NextGen PBN flight procedure requirements.</P>
                <P>The Air Traffic Service (ATS) routes affected by the planned decommissioning of the Beckley VOR are Jet Routes J-213 and J-526, and VOR Federal Airways V-59, V-258, and V-519. With the planned decommissioning of the Beckley VOR, the remaining ground-based NAVAID coverage in the area is insufficient to enable the continuity of the affected ATS routes. As such, proposed modifications to V-258 and V-519 would result in the airways being shortened and to J-213, J-526, and V-59 would result in the routes and airway being revoked.</P>
                <P>To address the proposed modifications to the affected ATS routes, pilots operating under instrument flight rules (IFR) could use adjacent Jet Routes J-6, J-8, J-24, J-48, and J-78 in the high-altitude stratum or use VOR Federal Airways V-16, V-45, V-115, V-133, V-140, and V-178 in the low-altitude stratum to navigate around the area affected. Additionally, pilots operating aircraft equipped with RNAV capabilities could also navigate using RNAV Routes Q-34, Q-50, Q-68, Q-75, and Q-80 in the high-altitude stratum; RNAV Route T-426, once amended by this action, in the low-altitude stratum; or point-to-point using the existing Fixes and waypoints (WP) that would remain in place to support continued operations though the affected area. Pilots operating under visual flight rules who elect to navigate via the affected VOR Federal airways could take advantage of the adjacent conventional routes or airways listed above, as well as the listed RNAV routes and point-to-point navigation, if properly equipped. Lastly, all pilots also have the option to request and receive radar vectors from air traffic control to transit the affected area.</P>
                <P>To further mitigate the proposed modifications to the affected VOR Federal airways, the FAA also proposes to modify RNAV Route T-426. T-426 would be extended northward from the DANCO, VA, WP to overlay and mitigate the proposed removal of the affected V-59 airway. The extended T-route would provide pilots with RNAV-equipped aircraft an alternative route through the affected area, reduce ATC sector workload and complexity, reduce pilot-to-controller communication, and support the FAA's continued NextGen efforts to modernize the NAS from a ground-based navigation system to a satellite-based system.</P>
                <HD SOURCE="HD1">The Proposal</HD>
                <P>The FAA is proposing to amend 14 CFR part 71 by amending VOR Federal Airways V-258 and V-519, and RNAV Route T-426; and revoking Jet Routes J-213 and J-526, and VOR Federal Airway V-59 due to the planned decommissioning of the Beckley, WV, VOR. The proposed ATS route actions are described below.</P>
                <P>
                    <E T="03">J-213:</E>
                     J-213 currently extends between the Armel, VA, VOR/DME and the Beckley, WV, VOR/DME. The FAA proposes to remove the route in its entirety.
                </P>
                <P>
                    <E T="03">J-526:</E>
                     J-526 currently extends between the Beckley, WV, VOR/DME and the Louisville, KY, VOR/Tactical Air Navigation (VORTAC). The FAA proposes to remove the route in its entirety.
                </P>
                <P>
                    <E T="03">V-59:</E>
                     V-59 currently extends between the Pulaski, VA, VORTAC and the Parkersburg, WV, VOR/DME. The FAA proposes to remove the airway in its entirety.
                </P>
                <P>
                    <E T="03">V-258:</E>
                     V-258 currently extends between the Charleston, WV, VOR/DME and the Danville, VA, VOR. The FAA proposes to remove the airway segment between the Charleston VOR/DME and the Roanoke, VA, VOR/DME. As amended, the airway would be changed to extend between the Roanoke VOR/DME and the Danville VOR. Additional amendments to the airway have been proposed in a separate rulemaking action.
                </P>
                <P>
                    <E T="03">V-519:</E>
                     V-519 currently extends between the Volunteer, TN, VORTAC and the Beckley, WV, VOR/DME. The FAA proposes to remove the airway segment between the Bluefield, WV, VOR/DME and the Beckley VOR/DME. As amended, the airway would be changed to extend between the Volunteer VORTAC and the Bluefield VOR/DME.
                </P>
                <P>
                    <E T="03">T-426:</E>
                     T-426 currently extends between the DANCO, WV, WP and the MCDON, VA, WP. The FAA proposes to extend the route northward from the DANCO WP to the Parkersburg, WV, VOR/DME. As amended, T-426 would extend between the Parkersburg VOR/DME and the MCDON WP and provide mitigation for the proposed V-59 airway removal. The full T-426 route description is listed in the regulatory text of this NPRM.
                </P>
                <P>All NAVAID radials listed in the VOR Federal airway descriptions in the proposed regulatory text of this notice of proposed rulemaking are unchanged and stated in degrees True north.</P>

                <P>
                    The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant 
                    <PRTPAGE P="42826"/>
                    regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

                <P>
                    The FAA's authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is 
                    <PRTPAGE P="42827"/>
                    promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it would establish Class E airspace extending upward from 700 feet above the surface at Wash Co Air 1 Base, Brenham, TX, to support instrument flight rule (IFR) operations at this airport.

                <HD SOURCE="HD1">Comments Invited</HD>
                <P>The FAA invites interested persons to participate in this rulemaking by submitting written comments, data, or views. Comments are specifically invited on the overall regulatory, aeronautical, economic, environmental, and energy-related aspects of the proposal. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should submit only one time if comments are filed electronically, or commenters should send only one copy of written comments if comments are filed in writing.</P>
                <P>The FAA will file in the docket all comments it receives, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments it received on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments it receives.</P>

                <P>The FAA is proposing to amend 14 CFR part 71 by:</P>
                <P>Establishing Class E airspace extending upward from 700 feet above the surface within a 6.1-mile radius of Wash Co Air 1 Base, Brenham, TX.</P>
                <P>This action is to support new instrument procedures and IFR operations at this airport.</P>
                <HD SOURCE="HD1">Regulatory Notices and Analyses</HD>
                <P>The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.</P>

                <P>
                    The FAA is planning to decommission the Mankato, KS, VOR in February 2025. The Mankato VOR was one of the candidate VORs identified for discontinuance by the FAA's VOR MON program and listed in the final policy statement notice, “Provision of Navigation Services for the Next Generation Air Transportation System 
                    <PRTPAGE P="42829"/>
                    (NextGen) Transition to Performance-Based Navigation (PBN) (Plan for Establishing a VOR Minimum Operational Network),” published in the 
                    <E T="04">Federal Register</E>
                     on July 26, 2016 (81 FR 48694), Docket No. FAA-2011-1082.
                </P>
                <P>Although the VOR portion of the Mankato, KS, VORTAC is planned for decommissioning, the co-located Tactical Air Navigation (TACAN) portion of the NAVAID is being retained. The TACAN would continue to provide navigational service for military operations and Distance Measuring Equipment (DME) service supporting current and future NextGen PBN flight procedure requirements.</P>
                <P>The VOR Federal airways affected by the Mankato VOR decommissioning are V-216, V-380, V-549, and V-551. With the planned decommissioning of the Mankato VOR, the remaining ground-based NAVAID coverage in the area is insufficient to enable the continuity of the affected airways. As such, proposed modifications to V-216 would result in an existing gap in the airway being expanded; to V-380 would result in the airway being shortened; and to V-549 and V-551 would result in the airways being revoked.</P>
                <P>To address the proposed modifications to the affected VOR Federal airways, pilots operating under instrument flight rules (IFR) may circumnavigate or fly through the affected area by requesting air traffic control (ATC) radar vectors since there are no alternate conventional airways available in the area. Additionally, pilots operating aircraft equipped with area navigation (RNAV) capabilities could navigate through the affected area point-to-point using the existing Fixes and waypoints (WP) that would remain in place or by using RNAV routes T-413, T-431, or T-468. Pilots operating under visual flight rules who elect to navigate via the affected VOR Federal airways may also take advantage of the ATC services and RNAV routes, if properly equipped, listed previously.</P>
                <HD SOURCE="HD1">The Proposal</HD>
                <P>The FAA is proposing to amend 14 CFR part 71 by amending VOR Federal Airways V-216 and V-380, and revoking VOR Federal Airways V-549 and V-551. The FAA is proposing this action due to the planned decommissioning of the VOR portion of the Mankato, KS, VORTAC. The proposed airway actions are described below.</P>
                <P>
                    <E T="03">V-216:</E>
                     V-216 currently extends between the Lamar, CO, VOR/Distance Measuring Equipment (VOR/DME) and the Mankato, KS, VORTAC; and between the Lamoni, IA, VOR/DME and the Janesville, WI, VOR/DME. The FAA proposes to remove the airway segment between the Hill City, KS, VORTAC and the Mankato VORTAC. As amended, the airway would be changed to extend between the Lamar VOR/DME and the Hill City VORTAC, and between the Lamoni VOR/DME and the Janesville VOR/DME. Additional amendments to the airway have been proposed in a separate rulemaking action.
                </P>
                <P>
                    <E T="03">V-380:</E>
                     V-380 currently extends between the Grand Island, NE, VOR/DME and the Mankato, KS, VORTAC. The FAA proposes to remove the airway segment between the Hastings, NE, VOR/DME and the Mankato VORTAC. As amended, the airway would be changed to extend between the Grand Island VOR/DME and the Hastings VOR/DME. Additional amendments to the airway have been proposed in a separate rulemaking action.

                <P>The FAA has determined that this proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore: (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.</P>

                    <P>The Environmental Protection Agency (EPA) is proposing to approve an October 27, 2023, submittal from the Wisconsin Department of Natural Resources (WDNR) to align provisions approved in the Wisconsin State Implementation Plan (SIP) with current Wisconsin administrative rules and statutes. WDNR requested that certain provisions previously approved into the Wisconsin SIP under now obsolete numbering schemes be renumbered to ensure citations in the Wisconsin SIP reflect the current numbering systems of the Wisconsin Administrative Code (WAC) and the Wisconsin Statutes (Wis. Stats.). WDNR also requested that EPA approve rule and statute provisions that have been revised since they were approved into the Wisconsin SIP. Finally, WDNR requested removal of rules and statutes from the Wisconsin SIP that are no longer in effect in Wisconsin. Approval of these changes in the Wisconsin SIP will not impact the state's air quality or ability to meet Clean Air Act (CAA) requirements.</P>

                <P>Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA.</P>
                <HD SOURCE="HD1">I. Background</HD>
                <P>Wisconsin's air pollution control rules were officially submitted for SIP approval on January 14, 1972, and approved into the SIP on May 31, 1972 (37 FR 10902), under Natural Resources (NR) chapter 154 of the Wisconsin Administrative Code (WAC). On October 1, 1986 (Wisconsin Register No. 369, September 1986), the air pollution control rules were renumbered from the NR 154 series to the NR 400 series. In addition, on May 1, 1995 (Wisconsin Register No. 472, April 1995), the air pollution control rules underwent a subsequent renumbering process within the NR 400 series. This has resulted with the Wisconsin SIP consisting of rules approved using the previous NR 154 citations, some NR 400 series rules prior to being renumbered on May 1, 1995, and NR 400 series rules under the current numbering system. The SIP revision submitted by WDNR on October 27, 2023, requests that the previous SIP rules approved under the obsolete numbering systems are renumbered to ensure that all the rules in the Wisconsin SIP are aligned with the WAC's current NR 400 numbering system.</P>
                <P>Similarly, Wisconsin Statutes addressing air pollution were originally submitted and approved into the Wisconsin SIP under Wis. Stats. chapter 144. The Wisconsin Statutes also underwent a renumbering under 1995 Wisconsin Act 227, where the air pollution statutes were moved from Wis. Stats. chapter 144 to Wis. Stats. chapter 285. This has resulted with the Wisconsin SIP consisting of Wisconsin air pollution statutes approved under both Wis. Stats. chapter 144 and Wis. Stats. chapter 285. The SIP revision submitted by WDNR on October 27, 2023, requests that the previously SIP statutes approved under Wis. Stats. chapter 144 are renumbered to ensure that all the rules in the Wisconsin SIP are aligned with the current numbering system under Wis. Stats. chapter 285.</P>
                <P>Further, there are some instances where rule and statute language was revised and some provisions were not retained by Wisconsin as part of, or after, the renumbering processes. The October 27, 2023, SIP revision also requests that EPA approve revised rule or statute language into the Wisconsin SIP to replace the provisions' former citations and language and to remove some provisions from the Wisconsin SIP that are no longer in effect in Wisconsin.</P>
                <HD SOURCE="HD1">II. Review of the Wisconsin Alignment SIP Submittal</HD>
                <P>As previously stated, the purpose of this SIP revision is to revise the current SIP approved Wisconsin administrative rules and statute provisions so that they are consistent with the current version of the Wisconsin rules and statutes. This will provide clarity to regulators, sources, and the public as to what has been approved into the Wisconsin SIP. To accomplish this WDNR requested that EPA revise the SIP by (1) replacing rules and statutes citations that were revised as part of, or after, the renumbering processes, and (2) approving provisions that were simply updated, but not renumbered, with the most current version of these rule or statute provisions. WDNR also requested that EPA remove certain provisions from the Wisconsin SIP that are no longer in effect in Wisconsin. These provisions were either repealed at the state level via rulemaking action, or were not retained in the WAC or Wis. Stats. during the renumbering processes. The following list identifies the most recent version of the state rules and statutes that contain all of the requested revisions:</P>

                </P>
                <P>WDNR's request was organized as follows: (1) Section 2 requests renumbering of current SIP-approved rules and statutes; (2) Section 3 requests approval of rules and statutes that were modified following initial EPA approval; and (3) Section 4 requests removal of provisions from the Wisconsin SIP that are no longer in effect.</P>
                <HD SOURCE="HD2">Section 2. Renumbering Request: Update Citations in the SIP</HD>
                <P>This section of the WDNR submittal identifies citations that were previously approved into the SIP under now obsolete numbering schemes. These citations have not undergone any language revisions since they were approved into the Wisconsin SIP, making this primarily an administrative action to update the citation numbers. Table 1 of the submittal contains NR 154 provisions that were approved into the SIP prior to the October 1986. Table 2 contains NR 400 provisions that were approved into the SIP between October 1986 and May 1995. Table 3 contains Wis. Stats. Chapter 144 provisions that were approved into the SIP prior to promulgation of 1995 Wisconsin Act 227. These changes are approvable because they do not impact the stringency of the Wisconsin SIP.</P>
                <HD SOURCE="HD2">Section 3. Approval Request: Incorporate Updated Provisions Into the SIP</HD>
                <P>This section of the WDNR submittal identifies provisions that were previously approved into the SIP under now obsolete numbering schemes and underwent language revisions by Wisconsin after they were approved into the SIP. This section also identifies provisions that were not renumbered, but contain language revisions since they were approved into the SIP. Approving these provisions updates the Wisconsin SIP to be consistent in both language and numbering with current Wisconsin rules and statues. Table 4 of the submittal contains NR 154 provisions that were renumbered and revised since they were approved into the SIP. Table 5 contains NR 400 provisions that were renumbered and revised since they were approved into the SIP. Table 6 contains Wis. Stats. Provisions that were renumbered and revised since they were approved into the SIP or are being approved into the SIP for the first time. These changes are approvable because the majority of these are administrative in nature and will not impact the stringency of the Wisconsin SIP. In some instances, the changes will increase the stringency of the Wisconsin SIP by replacing current SIP limits with more stringent limits, providing clarity to previously approved SIP provisions or by filling in gaps in the currently approved SIP rules. For example, table A2-1 of the submittal identifies sources that were subject to NR 154.11(4)(b) before the provision was revised and renumbered to NR 415.06(1). In this instance, more stringent emission limits apply to the sources under NR 415.06(1) than the limit that was required under NR 154.11(4)(b). Further, the revision updates cross-references to rules that were renumbered since they were SIP approved and improves the continuity of some rules where portions were approved under the current numbering system and other portions were approved under the old numbering system.</P>
                <HD SOURCE="HD2">Section 4. Removal Request</HD>
                <P>This section of the WDNR submittal identifies provisions that were previously approved into the SIP but were not retained during the renumbering processes, were repealed at the state level, or the associated CAA requirements were revised by Congress. Removing these provisions from the SIP will ensure the Wisconsin SIP reflects the rules and statutes currently being implemented in the state. Table 7 of the submittal contains WAC rules that are being removed from the Wisconsin SIP because they were repealed at the state level. Table 8 contains Wis. Stats. provisions that are being removed from the Wisconsin SIP because they were repealed at the state level. These changes are approvable because the provisions are no longer needed or have been replaced by other approved rules in the WI SIP.</P>
                <HD SOURCE="HD1">III. CAA Section 110(1)</HD>
                <P>Section 110(l) of the CAA provides that state submissions cannot be approved as SIP revisions if they interfere with applicable requirements concerning attainment and maintenance of the National Ambient Air Quality Standards (NAAQS), reasonable further progress, or any other applicable requirement of the CAA for any of the criteria pollutants. Appendix 1 of the WDNR submittal contains CAA section 110(l) non-interference demonstrations for each of the revised SIP provisions and of the provisions being removed from the Wisconsin SIP. More specifically, table A1-1 contains the 110(l) demonstrations for revision or removal of WAC rules and table A1-2 contains the 110(l) demonstrations for incorporation, revision, or removal of Wisconsin Statutes. In their submittal, WDNR certified that approval of the Section 3 provision updates and incorporations into the Wisconsin SIP and removal of the Section 4 provisions from the Wisconsin SIP will not result in emissions increases that will interfere with Wisconsin's attainment or maintenance of the NAAQS. Therefore, EPA finds that Wisconsin's request to revise or remove specific rules and statutes from the SIP will not interfere with attainment and maintenance of the NAAQS, reasonable further progress, or any other applicable requirement of the CAA, nor pose a risk to the permanence and compliance with attainment/unclassifiable designations in the state.</P>
                <HD SOURCE="HD1">IV. EPA Action</HD>
                <P>EPA is proposing to approve the SIP revision request submitted by Wisconsin on October 27, 2023. The revisions include primarily administrative changes to existing rules and updates to material adopted by reference related to rules in WAC Chapters 400, 415, 417, 431, 436, 445, 447, 492 and 493, and Wis. Stats. Chapters 15, 110, 285 and 299. Also, EPA is proposing to approve Wisconsin's request for the removal of the previously approved WAC rules and Wis. Stats. identified in section 4 of the WDNR submittal. Most of the provisions that WDNR has removed are from outdated Wis. Stats. that are obsolete. These provisions are no longer needed or have been replaced by other approved rules in the Wisconsin SIP.</P>
                <P>EPA believes that the revisions improve the clarity of the rules without affecting their stringency and therefore is proposing to approve the submitted revisions as SIP strengthening measures. The changes to the Wisconsin rules are consistent with EPA regulations and will not interfere with any applicable requirement of the CAA. Further, the revisions will provide clarity to regulators, sources and the public as to what has been approved into the Wisconsin SIP.</P>

                <P>Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. 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.C. 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 CAA.</P>
                <P>In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where 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. 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.” 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>WDNR did not evaluate EJ considerations as part of its SIP submittal; the CAA and applicable implementing regulations neither prohibit nor require such an evaluation. 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 E.O. 12898 of achieving EJ for people of color, low-income populations and Indigenous peoples.</P>

                <HD SOURCE="HD1">I. Summary</HD>
                <P>
                    On March 20, 2024, EPA published in the 
                    <E T="04">Federal Register</E>
                     (89 FR 19952) a proposed rule that would revise the RCRA regulations to clarify and add specificity to existing requirements for owners/operators of open burning and open detonation (OB/OD) units, including how and when to apply and implement the requirements in the permitting process.
                </P>
                <P>In 1980, EPA prohibited OB/OD of hazardous waste due to the potential risks to human health and the environment. EPA allowed one exception to this prohibition for OB/OD of waste explosives because at the time, there were no safe alternative treatment options for these wastes. Since that time, facilities have been required to determine and continue to evaluate whether alternatives are available. Recent findings from the National Academies of Sciences, Engineering, and Medicine and EPA identify several safe alternatives that are now available for certain types of explosive wastes. The proposed rule would improve implementation of requirements for how facilities must evaluate and use alternative technologies determined to be safe and available for treating waste explosives in lieu of OB/OD, and would set new minimum technical standards for OB/OD where it remains the only available treatment option.</P>
                <P>Specifically, EPA proposed to create new subparts for OB/OD units in parts 264 (applicable to permitted facilities) and 265 (applicable to interim status facilities). The new subparts contain requirements that would apply to all owners/operators conducting or seeking to conduct OB/OD of waste explosives, including activities conducted as part of RCRA cleanup and closure. The new subparts propose: certain requirements for OB/OD emergency permits and an exemption from the alternative technology evaluation and implementation regulations for the de minimis treatment of waste explosives by OB/OD; new provisions that would specify how and when owners/operators and permit authorities are to evaluate alternative treatment technologies for OB/OD, including specific information that would be required for facilities to demonstrate whether safe modes of treatment are available for specific waste streams and for waste analysis/characterization; new and revised regulatory provisions on timelines for implementing alternative technologies; wastes prohibited/restricted from OB/OD; technical standards for OB/OD units; delay of closure applicability to OB/OD units; clarifications to emergency provisions; and procedures for permitting of mobile treatment units (MTUs) for waste explosives.</P>
                <P>The comment period for the proposed rule was scheduled to end on May 20, 2024. Since publication, EPA has received requests to extend that comment period to allow for additional time to develop comments on the proposed rule. After considering the requests, EPA has decided to extend the comment period for an additional 31 days, through June 20, 2024.</P>

                <P>The Agricultural Bioterrorism Protection Act of 2002, as amended (7 U.S.C. 8401, referred to below as the Act) provides for the regulation of certain biological agents and toxins that have the potential to pose a severe threat to animal and plant health, or to animal and plant products. The Animal and Plant Health Inspection Service (APHIS) has the primary responsibility for implementing the provisions of the Act within the U.S. Department of Agriculture.</P>
                <P>In accordance with the Act, APHIS promulgated the select agent and toxin regulations found in 7 CFR part 331 and 9 CFR part 121. Paragraph (e) in § 121.3 of the select agent and toxin regulations states that an attenuated strain of a select agent or a select toxin modified to be less potent or toxic may be excluded from the requirements of the select agent and toxin regulations based upon a determination by the Administrator that the attenuated strain or modified toxin does not pose a severe threat to animal health or animal products.</P>
                <P>
                    African swine fever virus (ASFV) is listed as a select agent in § 121.3(b) of the select agent and toxin regulations. APHIS approved the initial regulatory exclusion for ASFV strain ASFV-G-ΔI177L, based on an application submitted in accordance with the select agent and toxin regulations and with review and recommendations from the Agriculture Interagency Select Agents and Toxins Technical Advisory Committee (Ag-ISATTAC) at a meeting on April 2, 2020. The exclusion became effective on April 3, 2020. Pursuant to § 121.3(e)(1) of the select agent and toxin regulations, APHIS listed the exclusion on the National Select Agent Registry website at

                    On February 7, 2024, APHIS withdrew the previously approved select agent regulatory exclusion for the ASFV-G-ΔI177L strain. APHIS will remove this strain from the list on the National Select Agency Registry website concurrent with this notice. APHIS notified all entities that were known to have the previously excluded ASFV strains that possession, use, and transfer of these ASFV strains must now comply with the select agent and toxin regulations in 9 CFR part 121. APHIS based the decision to withdraw the exclusion on newly acquired information obtained in February 2024 regarding safety and genome instability potentially leading to reversion of virulence that was unavailable to Ag-ISATTAC during the April 2020 discussion for regulatory exclusion. Recent 
                    <E T="03">in-vitro</E>
                     and 
                    <E T="03">in-vivo</E>
                     studies conducted for a European Union grant provided general information that under certain conditions, the strain can demonstrate an increase or reversion to virulence. More specifically, the ASFV-G-ΔI177L strain was adapted to growth on a Zuckermann macrophage (ZMAC) cell line, which is a porcine macrophage cell line that supports high levels of ASFV replication. The resulting virus used in back passage swine studies and upon a fifth passage in swine showed clinical signs and/or gross pathology that is consistent with ASFV infection. Due to the development of clinical signs and associated gross pathology that resulted from inoculation with the cell line adapted virus, APHIS determined that the ASFV-G-ΔI177L strain represents an increased risk under certain conditions. For these reasons, APHIS further determined that the ASFV-G-ΔI177L strain does not maintain acceptable attenuation to continue to remain excluded under § 121.3(e).
                </P>
                <P>With the publication of this notice, we are informing the public that we withdrew the previously approved select agent regulatory exclusion for the ASFV-G-ΔI177L strain, effective on February 7, 2024, and that the possession, use, and transfer of this ASFV strain must now comply with the select agent and toxin regulations in 9 CFR part 121. This notice serves as an official record and public notification of this action.</P>

                <HD SOURCE="HD1">I. Abstract</HD>
                <P>The Quarterly Survey of Foreign Airline Operators' Revenues and Expenses in the United States (BE-9) collects data from U.S. offices, agents, or other representatives of foreign airline operators that transport passengers or freight and express to or from the United States. A U.S. office, agent, or other representative of a foreign airline operator must report if total covered revenues or total covered expenses were $5 million or more in the previous year or are expected to be $5 million or more during the current year.</P>
                <P>The data are needed to monitor U.S. trade in transport services, to analyze the impact of these cross-border services on the U.S. and foreign economies, to compile and improve the U.S. economic accounts, to support U.S. commercial policy on trade in transport services, to conduct trade promotion, and to improve the ability of U.S. businesses to identify and evaluate market opportunities. The data are used in estimating the trade in transport services component of the U.S. international transactions accounts (ITAs) and national income and product accounts (NIPAs).</P>
                <P>The Bureau of Economic Analysis (BEA) is not proposing any changes to the survey reporting requirements or to the data items collected on the survey.</P>
                <P>BEA does not plan to change the exemption levels used for the current quarterly survey. BEA estimates there will be no change in the average number of burden hours per response. The language in the instructions and definitions will be reviewed and adjusted as necessary to clarify survey requirements.</P>
                <HD SOURCE="HD1">II. Method of Collection</HD>
                <P>BEA contacts potential respondents by mail at the end of each quarter. Respondents would be required to file the completed BE-9 forms within 30 days after the end of each quarter of the year. Reports would be required from each U.S. offices, agents, or other representatives of foreign airline operators that transport passengers to or from the United States, whose total covered revenues or total covered expenses were $5 million or more during the previous year or are expected to exceed that amount during the current year. Entities required to report will be contacted individually by BEA. Entities not contacted by BEA have no reporting responsibilities.</P>
                <P>
                    BEA offers its electronic filing option, the eFile system, for use in reporting on Form BE-9. For more information about eFile, go to 
                    <E T="03">www.bea.gov/efile</E>

                <P>Commerce is providing interested parties an opportunity to comment on the appropriate physical characteristics of ceramic tile to be reported in response to Commerce's AD questionnaires. This information will be used to identify the key physical characteristics of the subject merchandise in order to report the relevant cost of production (COP) accurately, as well as to develop appropriate product comparison criteria.</P>
                <P>
                    Interested parties may provide any information or comments that they feel are relevant to the development of an accurate list of physical characteristics. Specifically, they may provide comments as to which characteristics 
                    <PRTPAGE P="42838"/>
                    are appropriate to use as: (1) general product characteristics; and (2) product comparison criteria. We note that it is not always appropriate to use all product characteristics as product comparison criteria. We base product comparison criteria on meaningful commercial differences among products. In other words, although there may be some physical product characteristics utilized by manufacturers to describe ceramic tile, it may be that only a select few product characteristics take into account commercially meaningful physical characteristics. In addition, interested parties may comment on the order in which the physical characteristics should be used in matching products. Generally, Commerce attempts to list the most important physical characteristics first and the least important characteristics last.

                <P>
                    In order to consider the suggestions of interested parties in developing and issuing the AD questionnaires, all product characteristics comments must be filed by 5:00 p.m. ET on May 29, 2024, which is 20 calendar days from the signature date of this notice.

                <HD SOURCE="HD1">Determination of Industry Support for the Petition</HD>
                <P>Section 732(b)(1) of the Act requires that a petition be filed on behalf of the domestic industry. Section 732(c)(4)(A) of the Act provides that a petition meets this requirement if the domestic producers or workers who support the petition account for: (i) at least 25 percent of the total production of the domestic like product; and (ii) more than 50 percent of the production of the domestic like product produced by that portion of the industry expressing support for, or opposition to, the petition. Moreover, section 732(c)(4)(D) of the Act provides that, if the petition does not establish support of domestic producers or workers accounting for more than 50 percent of the total production of the domestic like product, Commerce shall: (i) poll the industry or rely on other information in order to determine if there is support for the petition, as required by subparagraph (A); or (ii) determine industry support using a statistically valid sampling method to poll the “industry.”</P>
                <P>
                    Section 771(4)(A) of the Act defines the “industry” as the producers as a whole of a domestic like product. Thus, to determine whether a petition has the requisite industry support, the statute directs Commerce to look to producers and workers who produce the domestic like product. The U.S. International Trade Commission (ITC), which is responsible for determining whether “the domestic industry” has been injured, must also determine what constitutes a domestic like product in order to define the industry. While both Commerce and the ITC must apply the same statutory definition regarding the domestic like product,
                    <SU>16</SU>
                    <FTREF/>
                     they do so for different purposes and pursuant to a separate and distinct authority. In addition, Commerce's determination is subject to limitations of time and information. Although this may result in different definitions of the like product, such differences do not render the decision of either agency contrary to law.

                    the Petition established support from domestic producers (or workers) accounting for more than 50 percent of the total production of the domestic like product and, as such, Commerce is not required to take further action in order to evaluate industry support (

                     Second, the domestic producers (or workers) have met the statutory criteria for industry support under section 732(c)(4)(A)(i) of the Act because the domestic producers (or workers) who support the Petition account for at least 25 percent of the total production of the domestic like product.
                    <SU>27</SU>

                     Finally, the domestic producers (or workers) have met the statutory criteria for industry support under section 732(c)(4)(A)(ii) of the Act because the domestic producers (or workers) who support the Petition account for more than 50 percent of the production of the domestic like product produced by that portion of the industry expressing support for, or opposition to, the Petition.

                    Based on the data provided by the petitioner, there is reason to believe that imports of ceramic tile from India are being, or are likely to be, sold in the United States at LTFV. Based on comparisons of EP to NV in accordance with sections 772 and 773 of the Act, the estimated dumping margins for ceramic tile for India are 328.14 to 489.36 percent.

                <P>
                    Section 773(e) of the Act addresses the concept of particular market situation (PMS) for purposes of CV, stating that “if a particular market situation exists such that the cost of materials and fabrication or other processing of any kind does not accurately reflect the cost of production in the ordinary course of trade, the administering authority may use another calculation methodology under this subtitle or any other calculation methodology.” When an interested party submits a PMS allegation pursuant to section 773(e) of the Act (
                    <E T="03">i.e.,</E>
                     a cost-based PMS allegation), Commerce will respond to such a submission consistent with 19 CFR 351.301(c)(2)(v). If Commerce finds that a cost-based PMS exists under section 773(e) of the Act, then it will modify its dumping calculations appropriately.
                </P>
                <P>Neither section 773(e) of the Act, nor 19 CFR 351.301(c)(2)(v), sets a deadline for the submission of cost-based PMS allegations and supporting factual information. However, in order to administer section 773(e) of the Act, Commerce must receive PMS allegations and supporting factual information with enough time to consider the submission. Thus, should an interested party wish to submit a cost-based PMS allegation and supporting new factual information pursuant to section 773(e) of the Act, it must do so no later than 20 days after submission of a respondent's initial section D questionnaire response.</P>
                <P>
                    We note that a PMS allegation filed pursuant to sections 773(a)(1)(B)(ii)(III) or 773(a)(1)(C)(iii) of the Act (
                    <E T="03">i.e.,</E>
                     a sales-based PMS allegation) must be filed within 10 days of submission of a respondent's initial section B questionnaire response, in accordance with 19 CFR 351.301(c)(2)(i) and 19 CFR 351.404(c)(2).

                <P>
                    Parties may request an extension of time limits before the expiration of a time limit established under 19 CFR 351.301, or as otherwise specified by Commerce. In general, an extension request will be considered untimely if it is filed after the expiration of the time limit established under 19 CFR 351.301, or as otherwise specified by Commerce.

                     For submissions that are due from multiple parties simultaneously, an extension request will be considered untimely if it is filed after 10:00 a.m. ET on the due date. Under certain circumstances, Commerce may elect to specify a different time limit by which extension requests will be considered untimely for submissions which are due from multiple parties simultaneously. In such a case, we will inform parties in a letter or memorandum of the deadline (including a specified time) by which extension requests must be filed to be considered timely. An extension request must be made in a separate, standalone submission; under limited circumstances we will grant untimely filed requests for the extension of time limits, where we determine, based on 19 CFR 351.302, that extraordinary circumstances exist. Parties should review Commerce's regulations concerning the extension of time limits and the

                    <P>The merchandise covered by this investigation is ceramic flooring tile, wall tile, paving tile, hearth tile, porcelain tile, mosaic tile, flags, decorative tile, finishing tile, and the like (hereinafter ceramic tile). Ceramic tiles are articles containing a mixture of minerals including clay (generally hydrous silicates of alumina or magnesium) that are fired so the raw materials are fused to produce a tile that is less than 3.2 cm in thickness, exclusive of decorative features. All ceramic tile is subject to the scope regardless of end use, surface area, and weight, regardless of whether the tile is glazed or unglazed, regardless of the water absorption coefficient by weight, regardless of the extent of vitrification, and regardless of whether or not the tile is on a backing. Subject merchandise includes ceramic tile “slabs” or “panels” (tiles that are larger than 1 meter2 (11 ft2)).</P>
                    <P>Subject merchandise includes ceramic tile that undergoes minor processing in a third country prior to importation into the United States. Similarly, subject merchandise includes ceramic tile produced that undergoes minor processing after importation into the United States. Such minor processing includes, but is not limited to, one or more of the following: beveling, cutting, trimming, staining, painting, polishing, finishing, additional firing, affixing a decorative surface to the tile, or any other processing that would otherwise not remove the merchandise from the scope of the investigation if performed in the country of manufacture of the in-scope product.</P>

                <P>In accordance with section 702(b)(1) of the Tariff Act of 1930, as amended (the Act), the petitioner alleges that the Government of India (GOI) is providing countervailable subsidies, within the meaning of sections 701 and 771(5) of the Act, to producers of ceramic tile in India, and that such imports are materially injuring, or threatening material injury to, the domestic industry producing ceramic tile in the United States. Consistent with section 702(b)(1) of the Act and 19 CFR 351.202(b), for those alleged programs on which we are initiating a CVD investigation, the Petition is supported by information reasonably available to the petitioner.</P>

                <HD SOURCE="HD1">Determination of Industry Support for the Petition</HD>
                <P>Section 702(b)(1) of the Act requires that a petition be filed on behalf of the domestic industry. Section 702(c)(4)(A) of the Act provides that a petition meets this requirement if the domestic producers or workers who support the petition account for: (i) at least 25 percent of the total production of the domestic like product; and (ii) more than 50 percent of the production of the domestic like product produced by that portion of the industry expressing support for, or opposition to, the petition. Moreover, section 702(c)(4)(D) of the Act provides that, if the petition does not establish support of domestic producers or workers accounting for more than 50 percent of the total production of the domestic like product, Commerce shall: (i) poll the industry or rely on other information in order to determine if there is support for the petition, as required by subparagraph (A); or (ii) determine industry support using a statistically valid sampling method to poll the “industry.”</P>
                <P>
                    Section 771(4)(A) of the Act defines the “industry” as the producers as a whole of a domestic like product. Thus, to determine whether a petition has the requisite industry support, the statute directs Commerce to look to producers and workers who produce the domestic like product. The U.S. International Trade Commission (ITC), which is responsible for determining whether “the domestic industry” has been injured, must also determine what constitutes a domestic like product in order to define the industry. While both Commerce and the ITC must apply the same statutory definition regarding the domestic like product,
                    <SU>16</SU>
                    <FTREF/>
                     they do so for different purposes and pursuant to a separate and distinct authority. In addition, Commerce's determination is subject to limitations of time and information. Although this may result in different definitions of the like product, such differences do not render the decision of either agency contrary to law.

                    In determining whether the petitioner has standing under section 702(c)(4)(A) of the Act, we considered the industry support data contained in the Petition with reference to the domestic like product as defined in the “Scope of the Investigation,” in the appendix to this notice. To establish industry support, the petitioner provided its own production of the domestic like product in 2023.

                    Our review of the data provided in the Petition, First General Issues Supplement, the Second Petition Supplement, and other information readily available to Commerce indicates that the petitioner has established industry support for the Petition.

                    <FTREF/>
                     First, the Petition established support from domestic producers (or workers) accounting for more than 50 percent of the total production of the domestic like product and, as such, Commerce is not required to take further action in order to evaluate industry support (
                    <E T="03">e.g.,</E>

                     Second, the domestic producers (or workers) have met the statutory criteria for industry support under section 702(c)(4)(A)(i) of the Act because the domestic producers (or workers) who support the Petition account for at least 25 percent of the total production of the domestic like product.
                    <SU>27</SU>
                    <FTREF/>
                     Finally, the domestic producers (or workers) have met the statutory criteria for industry support under section 702(c)(4)(A)(ii) of the Act because the domestic producers (or workers) who support the Petition account for more than 50 percent of the production of the domestic like product produced by that portion of the industry expressing support for, or opposition to, the Petition.

                    The petitioner contends that the industry's injured condition is illustrated by a significant and increasing volume of subject imports; increased subject market share; adverse impact on production, capacity utilization, and U.S. shipments; underselling and price depression and/or suppression; lost sales and revenues; adverse impact on profitability and returns on investments; cancellation, postponement, or rejection of expansion projects and reduced spending on research and development; and increase in inventories.

                    Based upon the examination of the Petition and supplemental responses, we find that they meet the requirements of section 702 of the Act. Therefore, we are initiating a CVD investigation to determine whether imports of ceramic tile from India benefit from countervailable subsidies conferred by the GOI. Based on our review of the Petition, we find that there is sufficient information to initiate a CVD investigation on 58 of 65 programs alleged by the petitioner.

                    Parties may request an extension of time limits before the expiration of a time limit established under 19 CFR 351.301, or as otherwise specified by Commerce.

                     For submissions that are due from multiple parties simultaneously, an extension request will be considered untimely if it is filed after 10:00 a.m. ET on the due date. Under certain circumstances, Commerce may elect to specify a different time limit by which extension requests will be considered untimely for submissions which are due from multiple parties simultaneously. In such a case, Commerce will inform parties in a letter or memorandum of the deadline (including a specified time) by which extension requests must be filed to be considered timely. An extension request must be made in a separate, stand-alone submission; under limited circumstances we will grant untimely filed requests for the extension of time limits, where we determine, based on 19 CFR 351.302, that extraordinary circumstances exist.

                    <E T="03">de minimis</E>
                     (

                    <E T="03">ad valorem</E>
                     antidumping duty assessment rates based on the ratio of the total amount of dumping calculated for the importer's examined sales to the total entered value of those same sales in accordance with 19 CFR 351.212(b)(1).

                    <FTREF/>
                     If the respondent has not reported entered values, we will calculate a per-unit assessment rate for each importer by dividing the total amount of dumping calculated for the examined sales made to that importer by the total quantity associated with those sales. We will instruct CBP to assess antidumping duties on all appropriate entries covered by this review when the importer-specific assessment rate calculated in the final results of this review is above 
                    <E T="03">de minimis</E>

                     0.50 percent). Where either the respondent's weighted-average dumping margin is zero or

                     or an importer-specific assessment rate is zero or

                     we will instruct CBP to liquidate the appropriate entries without regard to antidumping duties. The final results of this review shall be the basis for the assessment of antidumping duties on entries of merchandise covered by the final results of this review and for future deposits of estimated duties, where applicable.

                <P>The Gulf of Mexico, South Atlantic, and Caribbean Fishery Management Councils, in conjunction with NOAA Fisheries and the Atlantic and Gulf States Marine Fisheries Commissions, have implemented the Southeast Data, Assessment and Review (SEDAR) process, a multi-step method for determining the status of fish stocks in the Southeast Region. SEDAR is a three-step process including: (1) Data Workshop; (2) Assessment Process utilizing webinars; and (3) Review Workshop. The product of the Data Workshop is a data report which compiles and evaluates potential datasets and recommends which datasets are appropriate for assessment analyses. The product of the Assessment Process is a stock assessment report which describes the fisheries, evaluates the status of the stock, estimates biological benchmarks, projects future population conditions, and recommends research and monitoring needs. The assessment is independently peer reviewed at the Review Workshop. The product of the Review Workshop is a Summary documenting panel opinions regarding the strengths and weaknesses of the stock assessment and input data. Participants for SEDAR Workshops are appointed by the Gulf of Mexico, South Atlantic, and Caribbean Fishery Management Councils and NOAA Fisheries Southeast Regional Office, Highly Migratory Species Management Division, and Southeast Fisheries Science Center. Participants include: data collectors and database managers; stock assessment scientists, biologists, and researchers; constituency representatives including fishermen, environmentalists, and non-governmental organizations (NGOs); international experts; and staff of Councils, Commissions, and state and federal agencies.</P>
                <P>The items of discussion at the SEDAR 95 Atlantic Migratory Cobia Indices Webinar I are as follows:</P>
                <P>Discuss and review available indices of abundance and provide recommendations for their use in the assessment.</P>
                <P>Although non-emergency issues not contained in this agenda may come before this group for discussion, those issues may not be the subject of formal action during this meeting. Action will be restricted to those issues specifically identified in this notice and any issues arising after publication of this notice that require emergency action under section 305(c) of the Magnuson-Stevens Fishery Conservation and Management Act, provided the public has been notified of the intent to take final action to address the emergency.</P>

                    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 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 issued or, if the taking is limited to harassment, a notice of a proposed authorization is provided to the public for review.
                </P>
                <P>
                    An authorization for incidental takings shall be granted if NMFS finds that the taking will have a negligible impact on the species or stock(s), will 
                    <PRTPAGE P="42850"/>
                    not have an unmitigable adverse impact on the availability of the species or stock(s) for subsistence uses (where relevant), and if the permissible methods of taking and requirements pertaining to the mitigation, monitoring and reporting of such takings are set forth. NMFS has defined “negligible impact” in 50 CFR 216.103 as an impact resulting from the specified activity that cannot be reasonably expected to, and is not reasonably likely to, adversely affect the species or stock through effects on annual rates of recruitment or survival.
                </P>
                <P>Except with respect to certain activities not pertinent here, the MMPA defines “harassment” as: any act of pursuit, torment, or annoyance which (i) has the potential to injure a marine mammal or marine mammal stock in the wild (Level A harassment); or (ii) has the potential to disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns, including, but not limited to, migration, breathing, nursing, breeding, feeding, or sheltering (Level B harassment).</P>
                <P>On January 19, 2021, we issued a final rule with regulations to govern the unintentional taking of marine mammals incidental to geophysical survey activities conducted by oil and gas industry operators, and those persons authorized to conduct activities on their behalf (collectively “industry operators”), in U.S. waters of the GOM over the course of 5 years (86 FR 5322, January 19, 2021). The rule was based on our findings that the total taking from the specified activities over the 5-year period will have a negligible impact on the affected species or stock(s) of marine mammals and will not have an unmitigable adverse impact on the availability of those species or stocks for subsistence uses. The rule became effective on April 19, 2021.</P>
                <P>
                    Our regulations at 50 CFR 217.180 
                    <E T="03">et seq.</E>
                     allow for the issuance of LOAs to industry operators for the incidental take of marine mammals during geophysical survey activities and prescribe the permissible methods of taking and other means of effecting the least practicable adverse impact on marine mammal species or stocks and their habitat (often referred to as mitigation), as well as requirements pertaining to the monitoring and reporting of such taking. Under 50 CFR 217.186(e), issuance of an LOA shall be based on a determination that the level of taking will be consistent with the findings made for the total taking allowable under these regulations and a determination that the amount of take authorized under the LOA is of no more than small numbers.

                <HD SOURCE="HD1">Summary of Request and Analysis</HD>
                <P>CGG plans to conduct a three-dimensional (3D) ocean bottom node (OBN) survey over the Garden Banks and Keathley Canyon areas, with approximate water depths ranging from approximately 190 to 2,650 meters (m). See section F of the LOA application for a map of the area.</P>
                <P>
                    CGG anticipates using two source vessels, towing conventional airgun array sources consisting of 42 elements with a total volume of 5,220 cubic inches (in
                    <SU>3</SU>
                    ), or the low-frequency tuned pulse source (TPS). Please see CGG's application for additional detail.
                </P>
                <P>
                    The TPS was not included in the acoustic exposure modeling developed in support of the rule. However, the TPS was previously described and evaluated in the notice of issuance of a previous LOA to Shell (86 FR 37309, 37310; July 15, 2021; see also 87 FR 55790, 55791 (September 12, 2022 (notice of issuance of LOA to Shell)). For additional detail regarding sources, see Section C of the LOA application. Based on this information we have determined there will be no effects of a magnitude or intensity different from those evaluated in support of the rule. NMFS therefore expects that use of modeling results supporting the final rule relating to use of the 72 element, 8,000 in
                    <SU>3</SU>
                     airgun array are expected to be significantly conservative as a proxy for use in evaluating potential impacts of use of the TPS.

                    Consistent with the preamble to the final rule, the survey effort proposed by CGG in its LOA request was used to develop LOA-specific take estimates based on the acoustic exposure modeling results described in the preamble (86 FR 5398, January 19, 2021). In order to generate the appropriate take number for authorization, the following information was considered: (1) survey type; (2) location (by modeling zone

                    No 3D OBN surveys were included in the modeled survey types, and use of existing proxies (

                     2D, 3D NAZ, 3D WAZ, Coil) is generally conservative for use in evaluation of 3D OBN survey effort, largely due to the greater area covered by the modeled proxies. Summary descriptions of these modeled survey geometries are available in the preamble to the proposed rule (83 FR 29212, 29220, June 22, 2018). Coil was selected as the best available proxy survey type in this case because the spatial coverage of the planned survey is most similar to the coil survey pattern.

                     area covered, line spacing, number of sources, shot interval, total simulated pulses), NMFS considers area covered per day to be most influential on daily modeled exposures exceeding Level B harassment criteria. Although CGG is not proposing to perform a survey using the coil geometry, the coil proxy is most representative of the effort planned by CGG in terms of predicted Level B harassment exposures.

                    For some species, take estimates based solely on the modeling yielded results that are not realistically likely to occur when considered in light of other relevant information available during the rulemaking process regarding marine mammal occurrence in the GOM. The approach used in the acoustic exposure modeling, in which seven modeling zones were defined over the U.S. GOM, necessarily averages fine-scale information about marine mammal distribution over the large area of each modeling zone. Thus, although the modeling conducted for the rule is a natural starting point for estimating take, the rule acknowledged that other information could be considered (see,

For this survey, NMFS has other relevant information reviewed during the rulemaking that indicates use of the acoustic exposure modeling to generate a take estimate for two marine mammal species produces results inconsistent with what is known regarding their occurrence in the GOM. Accordingly, we have adjusted the calculated take estimates for those species as described below.

                     2016). However, whaling records suggest that Rice's whales historically had a broader distribution within similar habitat parameters throughout the GOM (Reeves

                     2011; Rosel and Wilcox, 2014). In addition, habitat-based density modeling has identified similar habitat (

                     approximately 100 to 400 m water depths along the continental shelf break) as being potential Rice's whale habitat (Roberts

                        <E T="03">Balaenoptera edeni</E>
                        ). These whales were subsequently described as a new species, Rice's whale (

                        ) (Rosel

                <P>
                    Although Rice's whales may occur outside of the core habitat area, we expect that any such occurrence would be limited to the narrow band of suitable habitat described above (
                    <E T="03">i.e.,</E>
                     100-400 m) and that, based on the few available records, these occurrences would be rare. CGG's planned activities will slightly overlap this depth range, with approximately 0.8 percent of the area expected to be ensonified by the survey above root-mean-squared pressure received levels (RMS SPL) of 160 dB (referenced to 1 micropascal (re 1 μPa)) overlapping the 100-400 m isobaths. Therefore, while we expect take of Rice's whale to be unlikely, there is some reasonable potential for take of Rice's whale to occur in association with this survey. However, NMFS' determination in reflection of the data discussed above, which informed the final rule, is that use of the generic acoustic exposure modeling results for Rice's whales would result in estimated take numbers that are inconsistent with the assumptions made in the rule regarding expected Rice's whale take (86 FR 5322, January 19, 2021; 86 FR 5403, January 19, 2021).

                    Killer whales are the most rarely encountered species in the GOM, typically in deep waters of the central GOM (Roberts 
                    <E T="03">et al.,</E>
                     2015; Maze-Foley and Mullin, 2006). As discussed in the final rule, the density models produced by Roberts 
                    <E T="03">et al.</E>
                     (2016) represent the output of models derived from multi-year observations and associated environmental parameters that incorporate corrections for detection bias. However, in the case of killer whales, the model is informed by few data, as indicated by the coefficient of variation associated with the abundance predicted by the model (0.41, the second-highest of any GOM species model; Roberts 
                    <E T="03">et al.,</E>
                     2016). The model's authors noted the expected non-uniform distribution of this rarely-encountered species (as discussed above) and expressed that, due to the limited data available to inform the model, it “should be viewed cautiously” (Roberts 
                    <E T="03">et al.,</E>
                     2015).

                    NOAA surveys in the GOM from 1992-2009 reported only 16 sightings of killer whales, with an additional 3 encounters during more recent survey effort from 2017-18 (Waring 
                    <E T="03">et al.,</E>

                    <E T="03">https://www.boem.gov/gommapps</E>
                    ). Two other species were also observed on fewer than 20 occasions during the 1992-2009 NOAA surveys (Fraser's dolphin and false killer whale).

                    <FTREF/>
                     However, observational data collected by protected species observers (PSOs) on industry geophysical survey vessels from 2002-2015 distinguish the killer whale in terms of rarity. During this period, killer whales were encountered on only 10 occasions, whereas the next most rarely encountered species (Fraser's dolphin) was recorded on 69 occasions (Barkaszi and Kelly, 2019). The false killer whale and pygmy killer whale were the next most rarely encountered species, with 110 records each. The killer whale was the species with the lowest detection frequency during each period over which PSO data were synthesized (2002-2008 and 2009-2015). This information qualitatively informed our rulemaking process, as discussed at 86 FR 5334 (January 19, 2021), and similarly informs our analysis here.

                    The rarity of encounters during seismic surveys is not likely to be the product of high bias on the probability of detection. Unlike certain cryptic species with high detection bias, such as 
                    <E T="03">Kogia</E>
                     spp. or beaked whales, or deep-diving species with high availability bias, such as beaked whales or sperm whales, killer whales are typically available for detection when present and are easily observed. Roberts 
                    <E T="03">et al.</E>
                     (2015) stated that availability is not a major factor affecting detectability of killer whales from shipboard surveys, as they are not a particularly long-diving species. Baird 
                    <E T="03">et al.</E>
                     (2005) reported that mean dive durations for 41 fish-eating killer whales for dives greater than or equal to 1 minute in duration was 2.3-2.4 minutes, and Hooker 
                    <E T="03">et al.</E>
                     (2012) reported that killer whales spent 78 percent of their time at depths between 0-10 m. Similarly, Kvadsheim 
                    <E T="03">et al.</E>
                     (2012) reported data from a study of 4 killer whales, noting that the whales performed 20 times as many dives 1-30 m in depth than to deeper waters, with an average depth during those most common dives of approximately 3 m.
                </P>
                <P>In summary, killer whales are the most rarely encountered species in the GOM and typically occur only in particularly deep water (&gt;700 m). This survey would take place in deep waters that would overlap with depths in which killer whales typically occur. While this information is reflected through the density model informing the acoustic exposure modeling results, there is relatively high uncertainty associated with the model for this species, and the acoustic exposure modeling applies mean distribution data over areas where the species is in fact less likely to occur. NMFS' determination in reflection of the data discussed above, which informed the final rule, is that use of the generic acoustic exposure modeling results for killer whales will generally result in estimated take numbers that are inconsistent with the assumptions made in the rule regarding expected killer whale take (86 FR 5403, January 19, 2021).</P>
                <P>
                    In past authorizations, NMFS has often addressed situations involving the low likelihood of encountering a rare species such as Rice's or killer whales in the GOM through authorization of take of a single group of average size (
                    <E T="03">i.e.,</E>
                     representing a single potential encounter). See 83 FR 63268, December 7, 2018; 86 FR 29090, May 28, 2021; 85 FR 55645, September 9, 2020. For the reasons expressed above, NMFS determined that a single encounter of Rice's whales or killer whales is more likely than the model-generated 
                    <PRTPAGE P="42852"/>
                    estimates and has authorized take associated with a single group encounter (
                    <E T="03">i.e.,</E>
                     up to two animals for Rice's whale and up to seven animals for killer whales).
                </P>
                <P>Based on the results of our analysis, NMFS has determined that the level of taking expected for this survey and authorized through the LOA is consistent with the findings made for the total taking allowable under the regulations. See table 1 in this notice and table 9 of the rule (86 FR 5322, January 19, 2021).</P>
                <HD SOURCE="HD1">Small Numbers Determination</HD>
                <P>Under the GOM rule, NMFS may not authorize incidental take of marine mammals in an LOA if it will exceed “small numbers.” In short, when an acceptable estimate of the individual marine mammals taken is available, if the estimated number of individual animals taken is up to, but not greater than, one-third of the best available abundance estimate, NMFS will determine that the numbers of marine mammals taken of a species or stock are small. For more information please see NMFS' discussion of the MMPA's small numbers requirement provided in the final rule (86 FR 5438, January 19, 2021).</P>
                <P>The take numbers for authorization are determined as described above in the Summary of Request and Analysis section. Subsequently, the total incidents of harassment for each species are multiplied by scalar ratios to produce a derived product that better reflects the number of individuals likely to be taken within a survey (as compared to the total number of instances of take), accounting for the likelihood that some individual marine mammals may be taken on more than 1 day (see 86 FR 5404, January 19, 2021). The output of this scaling, where appropriate, is incorporated into adjusted total take estimates that are the basis for NMFS' small numbers determinations, as depicted in table 1.</P>
                <P>
                    This product is used by NMFS in making the necessary small numbers determinations through comparison with the best available abundance estimates (see discussion at 86 FR 5391, January 19, 2021). For this comparison, NMFS' approach is to use the maximum theoretical population, determined through review of current stock assessment reports (SAR; 
                    <E T="03">https://www.fisheries.noaa.gov/national/marine-mammal-protection/marine-mammal-stock-assessments</E>
                    ) and model-predicted abundance information (
                    <E T="03">https://seamap.env.duke.edu/models/Duke/GOM/</E>
                    ). For the latter, for taxa where a density surface model could be produced, we use the maximum mean seasonal (
                    <E T="03">i.e.,</E>
                     3-month) abundance prediction for purposes of comparison as a precautionary smoothing of month-to-month fluctuations and in consideration of a corresponding lack of data in the literature regarding seasonal distribution of marine mammals in the GOM. Information supporting the small numbers determinations is provided in table 1.

                    Based on the analysis contained herein of CGG's proposed survey activity described in its LOA application and the anticipated take of marine mammals, NMFS finds that small numbers of marine mammals will be taken relative to the affected species or stock sizes (
                    <E T="03">i.e.,</E>
                     less than one-third of the best available abundance estimate) and therefore the taking is of no more than small numbers.

                <P>NMFS has determined that the level of taking for this LOA request is consistent with the findings made for the total taking allowable under the incidental take regulations and that the amount of take authorized under the LOA is of no more than small numbers. Accordingly, we have issued an LOA to CGG authorizing the take of marine mammals incidental to its geophysical survey activity, as described above.</P>

                <P>The Gulf of Mexico, South Atlantic, and Caribbean Fishery Management Councils, in conjunction with NOAA Fisheries and the Atlantic and Gulf States Marine Fisheries Commissions, have implemented the Southeast Data, Assessment and Review (SEDAR) process, a multi-step method for determining the status of fish stocks in the Southeast Region. SEDAR is a three-step process including: (1) Data Workshop; (2) Assessment Process utilizing webinars; and (3) Review Workshop. The product of the Data Workshop is a data report which compiles and evaluates potential datasets and recommends which datasets are appropriate for assessment analyses. The product of the Assessment Process is a stock assessment report which describes the fisheries, evaluates the status of the stock, estimates biological benchmarks, projects future population conditions, and recommends research and monitoring needs. The assessment is independently peer reviewed at the Review Workshop. The product of the Review Workshop is a Summary documenting panel opinions regarding the strengths and weaknesses of the stock assessment and input data. Participants for SEDAR Workshops are appointed by the Gulf of Mexico, South Atlantic, and Caribbean Fishery Management Councils and NOAA Fisheries Southeast Regional Office, Highly Migratory Species Management Division, and Southeast Fisheries Science Center. Participants include: data collectors and database managers; stock assessment scientists, biologists, and researchers; constituency representatives including fishermen, environmentalists, and non-governmental organizations (NGOs); international experts; and staff of Councils, Commissions, and state and federal agencies.</P>
                <P>The items of discussion at the SEDAR 92 Atlantic Blueline Tilefish LS-TWG Webinar II are as follows:</P>
                <P>Discuss available data sources, review preliminary analysis, and provide guidance for next steps.</P>
                <P>
                    Although non-emergency issues not contained in this agenda may come before this group for discussion, those issues may not be the subject of formal action during this meeting. Action will be restricted to those issues specifically identified in this notice and any issues arising after publication of this notice that require emergency action under section 305(c) of the Magnuson-Stevens

                <P>The Government of Argentina has requested to buy follow-on sustainment and support of their T-6 Texan aircraft fleet, to include the following aircraft hardware and software modifications and support: major and minor modifications include airframe and avionics improvements for reliability and integration of training munitions and external fuel tanks; aircraft and engine support equipment, components, consumables, spare parts and repair/return; publications and technical documentation; heavy maintenance support; other U.S. Government and contractor engineering, technical, and logistical support services, and related elements of program support. The estimated total cost is $73 million.</P>
                <P>This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of a major Non-NATO ally that is a force for political stability and economic progress in South America. It is in the U.S. national interest to assist Argentina in developing and maintaining a strong and ready self-defense capability.</P>
                <P>The proposed renewal of T-6 aircraft support will provide the Government of Argentina with the capability to meet current and future threats by revitalizing Argentina's trainer aircraft capabilities and to aid in the overall development of a professional pilot corps. Argentina is committed to modernizing its military and will have no difficulty absorbing the additional sustainment into its armed forces.</P>
                <P>The proposed sale of this equipment and support will not alter the basic military balance in the region.</P>
                <P>The principal contractor will be Textron Aviation Defense, Wichita, KS. There are no known offset agreements proposed in connection with this potential sale.</P>
                <P>Implementation of this proposed sale may require the assignment of additional U.S. Government and/or U.S. contractor representatives to Argentina to support program and financial management reviews.</P>
                <P>There will be no adverse impact on U.S. defense readiness as a result of this proposed sale. </P>

                <SUBJECT>Village of Swanton, Vermont; Notice of Authorization for Continued Project Operation</SUBJECT>
                <P>The license for the Highgate Falls Hydroelectric Project No. 2547 was issued for a period ending April 30, 2024.</P>
                <P>Section 15(a)(1) of the FPA, 16 U.S.C. 808(a)(1), requires the Commission, at the expiration of a license term, to issue from year-to-year an annual license to the then licensee(s) under the terms and conditions of the prior license until a new license is issued, or the project is otherwise disposed of as provided in section 15 or any other applicable section of the FPA. If the project's prior license waived the applicability of section 15 of the FPA, then, based on section 9(b) of the Administrative Procedure Act, 5 U.S.C. 558(c), and as set forth at 18 CFR 16.21(a), if the licensee of such project has filed an application for a subsequent license, the licensee may continue to operate the project in accordance with the terms and conditions of the license after the minor or minor part license expires, until the Commission acts on its application. If the licensee of such a project has not filed an application for a subsequent license, then it may be required, pursuant to 18 CFR 16.21(b), to continue project operations until the Commission issues someone else a license for the project or otherwise orders disposition of the project.</P>
                <P>If the project is subject to section 15 of the FPA, notice is hereby given that an annual license for Project No. 2547 is issued to the Village of Swanton, Vermont for a period effective May 1, 2024, through April 30, 2025, or until the issuance of a new license for the project or other disposition under the FPA, whichever comes first.</P>
                <P>
                    If issuance of a new license (or other disposition) does not take place on or before April 30, 2025, notice is hereby given that, pursuant to 18 CFR 16.18(c), an annual license under section 15(a)(1) of the FPA is renewed automatically without further order or notice by the Commission, unless the Commission orders otherwise.

                <P>On June 30, 2022, Union Falls Hydropower, L.P. filed a relicense application for the 2.6-megawatt Saranac Hydroelectric Project No. 4472 (project). The project is located on the Saranac River in Franklin and Clinton Counties, New York.</P>
                <P>In accordance with the Commission's regulations, on February 29, 2024, Commission staff issued a notice that the project was ready for environmental analysis (REA Notice). Based on the information in the record, including comments filed on the REA Notice, staff does not anticipate that licensing the project would constitute a major federal action significantly affecting the quality of the human environment. Therefore, staff intends to prepare an Environmental Assessment (EA) on the application to relicense the project.</P>
                <P>The EA will be issued and circulated for review by all interested parties. All comments filed on the EA will be analyzed by staff and considered in the Commission's final licensing decision.</P>

                <P>The license for the Tower and Kleber Hydroelectric Project No. 10615 was issued for a period ending April 30, 2024.</P>
                <P>Section 15(a)(1) of the FPA, 16 U.S.C. 808(a)(1), requires the Commission, at the expiration of a license term, to issue from year-to-year an annual license to the then licensee(s) under the terms and conditions of the prior license until a new license is issued, or the project is otherwise disposed of as provided in section 15 or any other applicable section of the FPA. If the project's prior license waived the applicability of section 15 of the FPA, then, based on section 9(b) of the Administrative Procedure Act, 5 U.S.C. 558(c), and as set forth at 18 CFR 16.21(a), if the licensee of such project has filed an application for a subsequent license, the licensee may continue to operate the project in accordance with the terms and conditions of the license after the minor or minor part license expires, until the Commission acts on its application. If the licensee of such a project has not filed an application for a subsequent license, then it may be required, pursuant to 18 CFR 16.21(b), to continue project operations until the Commission issues someone else a license for the project or otherwise orders disposition of the project.</P>
                <P>If the project is subject to section 15 of the FPA, notice is hereby given that an annual license for Project No. 10615 is issued to Tower Kleber Limited Partnership for a period effective May 1, 2024, through April 30, 2025, or until the issuance of a new license for the project or other disposition under the FPA, whichever comes first.</P>
                <P>If issuance of a new license (or other disposition) does not take place on or before April 30, 2025, notice is hereby given that, pursuant to 18 CFR 16.18(c), an annual license under section 15(a)(1) of the FPA is renewed automatically without further order or notice by the Commission, unless the Commission orders otherwise.</P>
                <P>If the project is not subject to section 15 of the FPA, notice is hereby given that Tower Kleber Limited Partnership is authorized to continue operation of the Tower and Kleber Hydroelectric Project under the terms and conditions of the prior license until the issuance of a subsequent license for the project or other disposition under the FPA, whichever comes first.</P>

                    <E T="03">Description of Request:</E>
                     The licensee submitted a request on behalf of Idaho Water Resources Board to allow the use and to occupy lands and waters inside the project boundary for the purposes of constructing a pumping station and an intake pipe. The lands inside the project boundary are administered by BLM. The facility would withdraw up to 2 cubic feet per second (cfs) (1.29 million gallons per day (MGD)) in the winter season (November to mid-March) and 6 cfs (3.88 MGD) in the summer season (mid-March through October). The anticipated average annual water withdrawal volume is approximately 1,800 acre-feet/year which would provide raw water to the Mountain Home Airforce Base water treatment plant. Discharged treated wastewater from the Airforce Base would be stored in a lagoon and used to irrigate a golf course under an Idaho Department of Environmental Quality Re-use Permit.

                    <E T="03">Project Description:</E>
                     The Moose River Project includes a dam that is comprised of: (1) a southern section that includes: (a) an earthen dike; (b) a concrete retaining wall; (c) a 39-foot-long concrete intake structure with: (i) a 3-foot-wide debris sluice gate; and (ii) a 15-foot-wide sluice gate equipped with an approximately 27-foot-wide trashrack with 2-inch clear bar spacing; and (d) a concrete section with a 10-foot-wide stoplog gate; and (2) a northern section that includes: (a) a south abutment; (b) a 240-foot-long spillway that has a crest elevation of 1,024.6 feet National Geodetic Vertical Datum of 1929 (NGVD 29) with a 58-foot-long, 0.5-foot-high notch; and (c) a north abutment.
                </P>
                <P>
                    The dam creates an impoundment that has a surface area of 21 acres at the spillway crest elevation of 1,024.6 feet NGVD, which is the normal maximum surface elevation of the impoundment. 
                    <PRTPAGE P="42870"/>
                    From the impoundment, water flows through the intake structure into: (1) an approximately 5,000-foot-long tunnel with a surge chamber; and (2) an approximately 90-foot-long penstock. From the impoundment, water also flows through the debris sluice gate and stoplog gate to an excavated rock channel that discharges into the Moose River approximately 100 feet downstream of the spillway. The penstock conveys water to an underground powerhouse that contains a 12.6-MW Kaplan turbine-generator unit. Water is discharged from the turbine to an approximately 82.5-foot-long tailrace. The project creates an approximately 6,200-foot-long bypassed reach of the Moose River.
                </P>
                <P>The project generator is connected to the regional electric grid by 13.8-kilovolt (kV) underground generator lead lines and a switchyard approximately 400 feet east of the powerhouse that includes a 13.8/115-kV step-up transformer.</P>
                <P>Project recreation facilities include: (1) Agers Falls Recreation Area that includes two picnic areas and a 900-foot-long interpretative trail through the historic Agers Mill Complex; (2) Moose River Trail that includes a one-mile-long trail on the shoreline of the bypassed reach; (3) a 230-foot-long boat portage trail from a hand-carry boat access site on the north side of the dam to a hand-carry boat access site approximately 300 feet downstream of the dam; and (4) a car-top boat launch located on the south shore of the impoundment, approximately 850 feet upstream of the dam.</P>
                <P>The minimum and maximum hydraulic capacities of the powerhouse are 200 and 1,300 cubic feet per second (cfs), respectively. The average annual energy production of the project from 2016 through 2022, was 51,350 megawatt-hours.</P>
                <P>The current license requires EONY to operate the project in an instantaneous run-of-river mode, such that project outflow approximates the “instantaneous sum of the inflow” to the impoundment. EONY maintains the normal maximum surface elevation of the impoundment at the spillway crest elevation of 1,024.6 feet NGVD 29 during non-winter months. During winter months, EONY maintains the surface elevation of the impoundment at 1,024.1 feet NGVD 29, which corresponds to the crest elevation of the notch in the spillway, to manage ice.</P>
                <P>The current license requires EONY to release a year-round minimum flow of 60 cfs or inflow, whichever is less, to the bypassed reach. EONY releases the minimum flow through the spillway notch, expect during the winter, when EONY releases the minimum flow through the stoplog gate. Under the current license, EONY is required to provide annual whitewater flow releases downstream of the dam on ten scheduled days and ten unscheduled days, from 12:00 to 7:00 p.m., or one-half hour prior to sunset, whichever is earlier. EONY is required to stop generating electricity during whitewater releases, except when project inflow exceeds 1,500 cfs. At flows above 1,500 cfs, EONY is required to release 1,000 cfs to the bypassed reach for whitewater recreation and can use the remainder of flow for electric generation. EONY is required to ramp down generation upon sign-in of the first boater, and increase flows to the bypassed reach gradually and in equal increments over a period of two hours to provide whitewater flows. Following a whitewater release, EONY ramps up generation upon sign-out of the last boater, and decreases flows to the bypassed reach gradually and in equal increments over a period of one hour.</P>
                <P>EONY proposes the following changes to the project boundary: (1) remove approximately 5.4 acres of land adjacent to the impoundment shoreline; (2) remove approximately 6.8 acres of land along the northern shoreline of the bypassed reach; (3) remove approximately 4.5 acres of land associated with Lyonsdale Road; and (4) add approximately 0.8 acre of land and water north of the hand-carry boat put-in site.</P>
                <P>EONY proposes to continue operating the project in a run-of-river mode and maintaining a normal maximum surface elevation of 1,024.6 feet NGVD 29 during non-winter months and 1,024.1 feet NGVD 29 during winter months. EONY also proposes to: (1) release a year-round minimum flow of 80 cfs or inflow, whichever is less, to the bypassed reach; (2) implement an impoundment drawdown and cofferdam plan, an invasive species management plan, and a bat and eagle management plan; (3) maintain an existing interpretative display and fencing for the protection of historic properties; (4) continue to operate and maintain existing project recreation facilities; (5) install signage at a hand-carry boat take-out site along the Moose River Trail; (6) continue to provide up to 20 whitewater flow releases per year; and (7) continue ramping during whitewater release days as outlined in the current license.</P>

                <HD SOURCE="HD1">Analysis of Agreement Containing Consent Order To Aid Public Comment</HD>
                <HD SOURCE="HD1">I. Introduction</HD>
                <P>The Federal Trade Commission (“Commission”) has accepted for public comment, subject to final approval, an Agreement Containing Consent Order (“Consent Agreement”) from Exxon Mobil Corporation (“Exxon”). Pursuant to an Agreement and Plan of Merger dated October 10, 2023 (“Merger Agreement”), Exxon and Pioneer Natural Resources Company (“Pioneer”) intend to combine their businesses through a merger (“the Proposed Acquisition”). The Proposed Acquisition will further enlarge Exxon—already the largest multinational supermajor oil company—and make Exxon by far the largest producer of crude oil in the Permian Basin, the United States' top oil-producing region. The purpose of the Consent Agreement is to remedy the anticompetitive effects that otherwise would result from the Proposed Acquisition.</P>
                <P>Through public statements and private communications, Pioneer founder and former CEO Scott D. Sheffield has campaigned to organize anticompetitive coordinated output reductions between and among U.S. crude oil producers, and others, including the Organization of Petroleum Exporting Countries (“OPEC”), and a related cartel of other oil-producing countries known as OPEC+. Rather than seeking to compete against OPEC and OPEC+ through independent competitive decision-making, Mr. Sheffield's goal in recent years at Pioneer has been to align U.S. oil production with OPEC and OPEC+ country output agreements, thereby cementing the cartel's position and sharing in the spoils of its market power.</P>
                <P>Under the terms of Exxon and Pioneer's Merger Agreement, Exxon is required to take all necessary actions to appoint Mr. Sheffield to Exxon's Board of Directors. Prior attempts to coordinate between Mr. Sheffield and firms representing a substantial share of the relevant market are highly informative as to the market's susceptibility to coordination. The appointment of Mr. Sheffield to Exxon's board as a result of the Proposed Acquisition will expand the scope of his reach to promote his anticompetitive messaging and therefore meaningfully increases the likelihood that these attempts at coordination will bear fruit. In particular, Mr. Sheffield's post-merger appointment to Exxon's board would give him a larger platform from which to advocate for greater industry-wide coordination as well as decision-making input on not only the largest producer in the Permian Basin, but also the largest multinational supermajor oil company. Under the terms of the proposed Decision and Order (“Order”), Exxon is prohibited from appointing Mr. Sheffield, current Pioneer employees, and certain other persons affiliated with Pioneer to its board, required to comply with section 8 of the Clayton Act, 15 U.S.C. 19, and required to attest on a regular basis that it is complying with the Order.</P>
                <P>The Consent Agreement is thus designed to remedy allegations in the Commission's Complaint that the Proposed Acquisition, if consummated, would violate section 7 of the Clayton Act, as amended, 15 U.S.C. 18, and section 5 of the FTC Act, as amended, 15 U.S.C. 45, by meaningfully increasing the risk of coordination in the relevant market. Absent a remedy, placing Mr. Sheffield on the Exxon board would harm the competitive process. The merger, if consummated, would also violate section 5 of the FTC Act by creating a board interlock among competitors. Mr. Sheffield currently serves on the board of The Williams Companies, Inc. (“Williams”), which operates a host of natural gas pipelines; natural gas gathering, processing, and treating assets; natural gas and natural gas liquids processing assets; crude oil transportation assets; and crude oil and natural gas production. Exxon and Williams are competitors of each other.</P>
                <P>
                    The proposed Order presents significant relief for these concerns and imposes effective and administrable relief. By restricting Mr. Sheffield and other Pioneer representatives from Exxon's board, the proposed Order makes clear that signaling coordinated price, output, or other competitive terms between market participants, 
                    <PRTPAGE P="42877"/>
                    particularly in the oil and gas industry, may give rise to legal liability. This Consent Order remedies the harm from the agreement to place Mr. Sheffield on the Exxon board. The Commission will continue to investigate mergers and acquisitions activity in the oil and gas industry and its risks to competition, as well as problematic unilateral signaling and coordination and attempted coordination among market participants.
                </P>
                <P>The Consent Agreement has been placed on the public record for 30 days for receipt of comments from interested persons. Comments received during this period will become part of the public record. After 30 days, the Commission will review the comments received and decide whether it should withdraw, modify, or finalize the proposed Order.</P>
                <HD SOURCE="HD1">II. The Merging Parties</HD>
                <P>Exxon is a public multi-national vertically integrated refiner and oil and gas producer, with revenues of over $340 billion and operations in the United States and worldwide. Exxon is headquartered in Spring, Texas, and operates refineries throughout the world that produce transportation fuels and petrochemicals.</P>
                <P>Pioneer is a public independent oil and gas company headquartered in Irving, Texas with revenues of nearly $20 billion. Pioneer produces crude oil and associated natural gas in the Permian Basin.</P>
                <HD SOURCE="HD1">III. The Agreement and Plan of Merger</HD>
                <P>On October 10, 2023, Exxon and Pioneer entered into the Merger Agreement, pursuant to which Exxon agreed to acquire Pioneer for an enterprise value of approximately $64.5 billion. The terms of the Merger Agreement state that Exxon “shall take all necessary actions to cause Scott D. Sheffield . . . . to be appointed to the board of directors” immediately following the consummation of the Proposed Acquisition. The Commission's Complaint alleges that this effect—Mr. Sheffield's appointment to the Exxon board—of the Proposed Acquisition, if consummated, would violate section 7 of the Clayton Act and section 5 of the FTC Act. Moreover, because Mr. Sheffield's appointment to Exxon's board would create a board interlock among competitors, the Proposed Acquisition, if consummated, would also violate section 5 of the FTC Act.</P>
                <HD SOURCE="HD1">IV. Relevant Market</HD>
                <P>A relevant product market in which to assess the Proposed Acquisition's anticompetitive effects is the development, production, and sale of crude oil. Crude oil is the main input to produce gasoline, diesel fuel, heating oil, and jet fuel. Crude oil purchasers generally cannot switch to alternative commodities without facing substantial costs. Exxon and Pioneer are engaged in the development, production, and sale of crude oil. A relevant geographic market in which to analyze the Proposed Acquisition is global.</P>
                <HD SOURCE="HD1">V. Effects of The Proposed Acquisition</HD>
                <P>The Commission's Complaint alleges that the Proposed Acquisition poses risks to competition by meaningfully increasing the risk of coordination among remaining firms in the relevant market. The 2023 Merger Guidelines identify three primary factors that indicate a merger may increase the risk of coordination, including the existence of prior actual or attempted attempts to coordinate in the market. If any of the three primary factors are met, the Agencies “may conclude that post-merger market conditions are susceptible to coordinated interaction and that the merger materially increases the risk of coordination.”</P>
                <P>Mr. Sheffield's history of attempting to coordinate with other oil industry participants suggests that the market is susceptible to anticompetitive coordination—a risk the Proposed Acquisition would only heighten. The Commission's Complaint lays out evidence, including from Mr. Sheffield's own public and private statements, of his campaign to organize anticompetitive coordinated output reductions between and among U.S. crude oil producers, and others, including OPEC and OPEC+. Much of this coordination has been with high-ranking OPEC representatives, thus indicating that firms with a substantial share of the relevant market have engaged in this conduct. By installing Mr. Sheffield on Exxon's Board, the Proposed Acquisition risks amplifying his public messaging and the effectiveness of his private contacts with OPEC, thereby meaningfully increasing the likelihood of coordination in the relevant market.</P>
                <HD SOURCE="HD1">VI. The Proposed Order</HD>
                <P>The proposed Order imposes several terms to remedy these concerns. First, the proposed Order prohibits Exxon from appointing Scott Sheffield to Exxon's board—as required by the Merger Agreement—or to serve in an advisory capacity to Exxon's board or Exxon's management. Second, for a period of five years, Exxon is also prohibited from appointing Pioneer's current employees and certain other persons affiliated with Pioneer to its board.</P>
                <P>Third, the proposed Order prohibits Exxon's directors and officers from serving as a director or officer of another corporation if that interlock would violate section 8 of the Clayton Act.

                <HD SOURCE="HD1">Statement of Chair Lina M. Khan</HD>
                <P>A core principle that should underpin the Commission's antitrust analysis is examining and understanding commercial realities. Sometimes the evidence that is most probative of commercial realities is how market participants act. Staff's investigation here uncovered troubling evidence of Pioneer CEO Scott Sheffield's actions and communications, which make clear that he believed and acted as if he could persuade his rivals to join him in colluding to restrict output and raise prices. When market actors speak and act as if they can collude, we should not ignore this direct evidence or subordinate it to less direct indicators of market realities.</P>
                <P>
                    The dissent does not dispute that Mr. Sheffield has tried to facilitate a cartel, nor does it suggest he will stop doing so after being elevated to the Exxon Board of Directors. Instead, the dissent suggests that Mr. Sheffield is wasting 
                    <PRTPAGE P="42878"/>
                    his time because he is unlikely to succeed.
                </P>
                <P>We should be wary of dispensing with regulatory humility. Corporate executives are not always credible narrators. But when corporate executives' words or actions reveal, against their interests, a belief that they can collude, we should generally believe them.</P>
                <HD SOURCE="HD1">Concurring Statement of Commissioner Rebecca Kelly Slaughter</HD>
                <P>Today's complaint and consent decree are an important step forward in merger investigations and enforcement. I'm very glad that we are able, through this consent decree, to prevent the substantial lessening of competition that would have occurred from one component of the merger: elevating Scott Sheffield to the board of directors of Exxon.</P>
                <P>
                    This complaint and consent decree reflect what I have long believed to be true: the management and business intentions of merging parties should matter to our assessment of the likely effects of a merger on competition. When a company agrees, as a condition of a merger, to elevate one of the industry's notorious public and private advocates of output coordination to its board, we can and should take that seriously as a competitive effect of the merger. This principle applies not just in oil and gas markets like the ones we assess today, but across the American economy.

                         Indeed, it may be particularly relevant in pharmaceuticals. The FTC has an entire division dedicated to investigation anticompetititive conduct in healthcare markets with a particularly strong enforcement track record in the pharmaceutical space. When pharmaceutical companies that have a history of anticompetitive conduct merge, I have long believed we should consider that history in our assessment of the likely competitive effects of the merger.

                <P>This is not to say that we should trust everything merging parties say in their effort to get a merger through the review process. The economic incentives of the merged firm continue to play a central role. If we find reason to believe that the merged firm, acting on those incentives, may substantially lessen competition, we should act. Corporate executives may profess that they plan to continue to compete as if those incentives don't exist. In that situation, enforcers must be highly skeptical. The parties have every reason to want to present a pro-competitive strategy to try to get their merger through. That is why we rely on ordinary course documents and business evidence to give us a clearer picture of how parties will behave. And when they openly embrace anticompetitive strategies, that is when we should take notice.</P>
                <P>I agree with my dissenting colleagues that another appropriate response to the concerning statements around coordinated behavior uncovered in this investigation would be to separately scrutinize them as a potential antitrust violation. Today's complaint and consent decree should not be seen as mutually exclusive with such a conduct investigation. Conduct investigations—rightly—are not subject to the strict statutory deadlines of merger investigations, and for a variety of reasons tend to take much longer. The harms to competition identified in the complaint are specific to this merger, and therefore they are appropriate to address now, at the time of the merger.</P>
                <P>
                    Lastly, it's important to reiterate here that the FTC does not approve mergers under any circumstances. This consent decree, like any other consent decree, should not be seen as resolving all competitive concerns this merger may present.

                    <FTREF/>
                     Enforcers are always faced with tradeoffs to weigh in our decisions. This consent decree will have an important and meaningful impact on the market and competition. It is worth doing now, whether or not further intervention may be warranted.

                         This is especially true given that the merging parties often have outsized control over the timing and timeline of FTC investigations. To ensure that enforcers can adequately and thoroughly investigate potentially unlawful mergers, lawmakers should amend the HSR Act to extend statutory deadlines.

Sheffield. . . to be appointed to [its] board of directors. . . immediately following the Effective Time” of the merger somehow does not place Mr. Sheffield on that board as a result of the merger.

                    The Commission has issued a Complaint and Order against Exxon Mobil Corporation (“Exxon”) on the 
                    <PRTPAGE P="42879"/>
                    ground that the proposed acquisition of Pioneer Natural Resources Company (“Pioneer”) would violate section 7 of the Clayton Act.

                    <FTREF/>
                     The principal ground on which the Commission proceeds is that the merger may substantially lessen competition because of the prospect that Exxon's shareholders may elect Scott Sheffield—Pioneer's founder, former CEO, and current board member—to Exxon's board of directors. The Complaint alleges that Mr. Sheffield has made “previous efforts to organize tacit (and potentially express) coordination of capital investment discipline and oil production levels.”

                    <FTREF/>

                    Antitrust enforcers have long recognized that a transaction which increases the risk of coordination also increases the risk of a substantial diminution of competition. Until recently, we considered three factors in assessing the risk of increased coordination: whether the transaction created “(1) a significant increase in concentration, leading to a moderately or highly concentrated market”; whether the transaction involved “(2) a market vulnerable to coordinated conduct”; and whether we had “(3) a credible basis for concluding the transaction will enhance that vulnerability.”

                    The 2023 Guidelines provide that “attempts to coordinate” are relevant to the risk-of-coordination inquiry where “firms representing a substantial share in the relevant market appear to have previously engaged in express or tacit coordination . . . .”

                     The Complaint alleges only that a combined OPEC and OPEC+ “account for over 50% of global crude oil production.”

                    <FTREF/>
                     Importantly, it does not allege the merging parties' market shares at all. As such, it fails to allege that either Exxon or Pioneer represents part of any “substantial share” of the market, and for good reason: the post-merger firm's share in the alleged market will not be substantial. The concentration in this market, and thus, the likelihood of successful coordination post-merger, are virtually unchanged by the proposed acquisition.

                         To be clear, we do not contend that every individual oil producer is a meaningful constraint on coordination. The Commission's Complaint is silent, however, on the existence or sufficiency of any other firm to constrain the coordination the consent purports to prevent with this remedy. For us, this omission precludes reason to believe the proposed transaction may substantially lessen competition.

                    The Complaint also focuses on the fact that the merger would give Mr. Sheffield “a larger platform from which to advocate for greater industry-wide coordination as well as decision-making input.” 
                    <SU>11</SU>
                    <FTREF/>
                     Mr. Sheffield's alleged prior conduct certainly raises serious concern and warrants antitrust scrutiny. But the merger does not place Mr. Sheffield on the board.
                    <SU>12</SU>
                    <FTREF/>
                     That decision belongs to Exxon's shareholders. The Commission acts today based only on the risk that the shareholders might elect him to the board, and that his election might give him a “larger platform” to coordinate—if indeed this market is susceptible to coordination. We do not believe this alleged risk presents a section 7 problem. Further, we are especially concerned with the Complaint's focus on Sheffield's past conduct at Pioneer as an indicator of Exxon's future actions, without any discussion of whether Exxon has incentives to engage in the same behavior. Focusing on individuals' conduct divorced from a firm's incentives could have troubling ramifications for future enforcement actions.

                <P>The alleged conduct by Mr. Sheffield warrants scrutiny, but that does not mean we have reason to believe the transaction violates section 7. The Commission should not leverage its merger enforcement authority—or any authority—the way it does today. We respectfully dissent.</P>

                     CMS is mandated to identify and implement measures to prevent fraud and abuse in the Medicare program. To meet this challenge, CMS has moved forward to improve the quality of the process for enrolling suppliers into the Medicare program by establishing a uniform application for enumerating suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS). Implementation of enhanced procedures for verifying the enrollment information has also improved the enrollment process. As part of this process, verification of compliance with supplier standards is necessary. The site investigation form has been used in the past to aid the Medicare contractor (the National Supplier Clearinghouse and/or its subcontractors) in verifying compliance with the required supplier standards found in 42 CFR 424.57(c). The primary function of the site investigation form is to provide a standardized, uniform tool to gather information from a DMEPOS supplier that tells us whether it meets certain qualifications to be a DMEPOS supplier (as found in 42 CFR 424.57(c)) and where it practices or renders its services.

                     Prior Authorization Process and Requirements for Certain Hospital Outpatient Department (OPD) Services; 
                    <E T="03">Use:</E>
                     Section 1833(t)(2)(F) of the Act authorizes CMS to develop a method for controlling unnecessary increases in the volume of covered OPD services. CMS believes the increases in volume associated with certain covered OPD services are unnecessary because the data show that the volume of utilization of these OPD service categories far exceeds what would be expected in light of the average rate-of-increase in the number of Medicare beneficiaries. Therefore, CMS is using the authority under section 1833(t)(2)(F) of the Act to require prior authorization for certain covered OPD services as a condition of Medicare payment. The reviews conducted under the program help to reduce unnecessary utilization and payments for these services. The information required for the prior authorization request includes all documentation necessary to show that the service meets applicable Medicare coverage, coding, and payment rules. Trained clinical reviewers at the Medicare Administrative Contractors (MACs) receive and review the information required for this collection. Review of that documentation is used to determine if the requested services are medically necessary and meet Medicare requirements to help reduce unnecessary increases for these services.

                    <E T="03">Description:</E>
                     In fiscal year 2023, OCS began administering the MLP+ program, which was appropriated in HR 117-403, Departments of Labor, Health and Human Services, and Related Agencies Appropriations Bill, 2023 through the Social Services Research Demonstration program. OCS awarded $1.6 million to eight MLPs to expand and strengthen the delivery of legal and social services that address health-harming needs for families and individuals with low incomes. The proposed information collection will support program performance monitoring, the provision of technical assistance to grant recipients, and an implementation evaluation. This information collection includes the following activities:
                </P>
                <P>• Collecting program data describing implementation, outcomes, and participant characteristics through a narrative quarterly Performance Progress Report (PPR) and a semi-annual report.</P>
                <P>• Conducting interviews with program directors to better understand their program implementation efforts and responses to client needs.</P>
                <P>• Conducting interviews with members of the legal team to better understand their program implementation efforts and responses to client needs.</P>
                <P>• Conducting interviews with members of the social services team to better understand their program implementation efforts and responses to client needs.</P>
                <P>• Conducting interviews with members of the clinical team to better understand their program implementation efforts and responses to client needs.</P>
                <P>• Conducting individual patient interviews with beneficiary clients to understand their needs and experiences with the medical, legal, and social services offered through the medical-legal partnership.</P>
                <P>
                    <E T="03">Respondents:</E>
                     There will be three types of respondents to the proposed instruments. First, the direct beneficiaries, the clients working with the MLP teams, will participate in the patient interviews and provide information about their characteristics, needs, and outcomes for the grant recipients' semi-annual reporting. Second, the program directors, legal staff, clinical staff, and social services staff will respond to interview instruments tailored to their roles. Grant recipients and project partners will also be asked to supply information that grant recipients will compile for quarterly PPRs and semi-annual reports, which will include information aggregated across partner sites and individuals participating in the program.

                     Section 641A of the Head Start Act, 42 U.S.C. 9836A, directs the U.S. Department of Health and Human Services (HHS) to develop “scientifically based and developmentally appropriate education performance standards related to school readiness” and “ensure that any such revisions in the standards do not result in the elimination of or any reduction in quality, scope, or types of health, educational, parental involvement, nutritional, social, or other services.” This information collection is entirely record keeping and does not contain any standardized instruments to provide flexibility for local programs. These records are intended to act as a tool for grantees and delegate agencies to be used in their day-to-day operations. For example, this includes the requirement that programs maintain a waiting list of eligible families. There are currently no changes to the record keeping requirements. However, if any proposed changes from the Notice of Proposed Rulemaking on Supporting the Head Start Workforce and Consistent Quality Programming (88 FR 80818), this information collection will be updated to reflect those changes.

                     Head Start grant recipients. Depending on the standard, the calculated burden hours is based on the individual enrollee, family, grant, program, or staff. In a few cases, only a proportion of one of these may apply.

                    <P>The Food and Drug Administration (FDA or Agency) is announcing the issuance of Emergency Use Authorizations (EUAs) (the Authorizations) for certain medical devices related to Coronavirus Disease 2019 (COVID-19). FDA has issued the Authorizations listed in this document under the Federal Food, Drug, and Cosmetic Act (FD&amp;C Act). These Authorizations contain, among other things, conditions on the emergency use of the authorized products. The Authorization follows the February 4, 2020, determination by the Secretary of Health and Human Services (HHS), as amended on March 15, 2023, that there is a public health emergency, or a significant potential for a public health emergency, that affects, or has a significant potential to affect, national security or the health and security of U.S. citizens living abroad and that involves the virus that causes COVID-19, and the subsequent declarations on February 4, 2020, March 2, 2020, and March 24, 2020, that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of the virus that causes COVID-19, personal respiratory protective devices, and medical devices, including alternative products used as medical devices, respectively, subject to the terms of any authorization issued under the FD&amp;C Act. These Authorizations, which include an explanation of the reasons for issuance, are listed in this document, and can be accessed on FDA's website from the links indicated.</P>

                <P>Section 564 of the FD&amp;C Act (21 U.S.C. 360bbb-3) allows FDA to strengthen the public health protections against biological, chemical, radiological, or nuclear agent or agents. Among other things, section 564 of the FD&amp;C Act allows FDA to authorize the use of an unapproved medical product or an unapproved use of an approved medical product in certain situations. With this EUA authority, FDA can help ensure that medical countermeasures may be used in emergencies to diagnose, treat, or prevent serious or life-threatening diseases or conditions caused by a biological, chemical, radiological, or nuclear agent or agents when there are no adequate, approved, and available alternatives.</P>
                <P>
                    Section 564(b)(1) of the FD&amp;C Act provides that, before an EUA may be issued, the Secretary of HHS must declare that circumstances exist justifying the authorization based on one of the following grounds: (1) a determination by the Secretary of Homeland Security that there is a domestic emergency, or a significant potential for a domestic emergency, involving a heightened risk of attack with a biological, chemical, radiological, or nuclear agent or agents; (2) a determination by the Secretary of Defense that there is a military emergency, or a significant potential for 
                    <PRTPAGE P="42886"/>
                    a military emergency, involving a heightened risk to U.S. military forces, including personnel operating under the authority of title 10 or title 50 of the U.S. Code, of attack with (A) a biological, chemical, radiological, or nuclear agent or agents; or (B) an agent or agents that may cause, or are otherwise associated with, an imminently life-threatening and specific risk to U.S. military forces;

                    <FTREF/>
                     (3) a determination by the Secretary of HHS that there is a public health emergency, or a significant potential for a public health emergency, that affects, or has a significant potential to affect, national security or the health and security of U.S. citizens living abroad, and that involves a biological, chemical, radiological, or nuclear agent or agents, or a disease or condition that may be attributable to such agent or agents; or (4) the identification of a material threat by the Secretary of Homeland Security pursuant to section 319F-2 of the Public Health Service (PHS) Act (42 U.S.C. 247d-6b) sufficient to affect national security or the health and security of U.S. citizens living abroad.

                        <SU>1</SU>
                         In the case of a determination by the Secretary of Defense, the Secretary of HHS shall determine within 45 calendar days of such determination, whether to make a declaration under section 564(b)(1) of the FD&amp;C Act, and, if appropriate, shall promptly make such a declaration.

                <P>
                    Once the Secretary of HHS has declared that circumstances exist justifying an authorization under section 564 of the FD&amp;C Act, FDA may authorize the emergency use of a drug, device, or biological product if the Agency concludes that the statutory criteria are satisfied. Under section 564(h)(1) of the FD&amp;C Act, FDA is required to publish in the 
                    <E T="04">Federal Register</E>
                     a notice of each authorization, and each termination or revocation of an authorization, and an explanation of the reasons for the action. Under section 564(h)(1) of the FD&amp;C Act, revisions to an authorization shall be made available on the internet website of FDA. Section 564 of the FD&amp;C Act permits FDA to authorize the introduction into interstate commerce of a drug, device, or biological product intended for use when the Secretary of HHS has declared that circumstances exist justifying the authorization of emergency use. Products appropriate for emergency use may include products and uses that are not approved, cleared, or licensed under section 505, 510(k), 512, or 515 of the FD&amp;C Act (21 U.S.C. 355, 360(k), 360b, or 360e) or section 351 of the PHS Act (42 U.S.C. 262), or conditionally approved under section 571 of the FD&amp;C Act (21 U.S.C. 360ccc). FDA may issue an EUA only if, after consultation with the HHS Assistant Secretary for Preparedness and Response, the Director of the National Institutes of Health, and the Director of the Centers for Disease Control and Prevention (to the extent feasible and appropriate given the applicable circumstances), FDA

                <P>On May 28, 2021, FDA approved NDA 214622 for TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, for the treatment of adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma (advanced bile duct cancer or advanced cholangiocarcinoma) with a fibroblast growth factor receptor 2 fusion or other rearrangement as detected by an FDA-approved test, under the Agency's accelerated approval regulations, 21 CFR part 314, subpart H. The accelerated approval of TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, for advanced bile duct cancer or advanced cholangiocarcinoma included required postmarketing trials intended to verify the clinical benefit of TRUSELTIQ.</P>
                <P>On October 5, 2022, Helsinn voluntarily requested withdrawal of approval of TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg. On February 15, 2023, FDA recommended that the applicant submit a letter to voluntarily request withdrawal of approval of TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, according to § 314.150(d) (21 CFR 314.150(d)) due to the company's inability to conduct a clinical trial to verify clinical benefit. On April 21, 2023, FDA requested Helsinn waive its opportunity for a hearing.</P>
                <P>
                    On May 30, 2023, Helsinn submitted a letter asking FDA to withdraw approval of NDA 214622 for TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, according to § 314.150(d) and waiving its opportunity for a hearing. In its letter requesting withdrawal of approval, Helsinn stated that it is voluntarily requesting withdrawal due to difficulties in recruiting and enrolling study subjects for the required confirmatory clinical trial in first line cholangiocarcinoma (a new indication under investigation for TRUSELTIQ), and the determination that, as a result, continued distribution of TRUSELTIQ in second line cholangiocarcinoma (the accelerated approval indication) is not commercially reasonable. Helsinn stated 
                    <PRTPAGE P="42888"/>
                    that it agreed to withdrawal of the application for this reason only.
                </P>
                <P>For the reasons discussed above, and in accordance with the applicant's request, approval of NDA 214622 for TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, and all amendments and supplements thereto, is withdrawn under § 314.150(d). Distribution of TRUSELTIQ (infigratinib phosphate) Capsules, 25 mg and 100 mg, into interstate commerce without an approved application is illegal and subject to regulatory action (see sections 505(a) and 301(d) of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355(a) and 331(d))).</P>

                <P>FDA is announcing the issuance of a priority review voucher to the sponsor of an approved rare pediatric disease product application. Under section 529 of the FD&amp;C Act (21 U.S.C. 360ff), FDA will award priority review vouchers to sponsors of approved rare pediatric disease product applications that meet certain criteria. FDA has determined that XOLREMDI (mavorixafor), manufactured by X4 Pharmaceuticals, Inc., meets the criteria for a priority review voucher. XOLREMDI (mavorixafor) is indicated for the treatment of WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome in patients 12 years of age and older to increase the number of circulating mature neutrophils and lymphocytes.</P>

                <P>The Federal Emergency Management Agency (FEMA) makes the final flood hazard determinations as shown in the LOMRs for each community listed in the table below. Notice of these modified flood hazard determinations has been published in newspapers of local circulation and 90 days have elapsed since that publication. The Deputy Associate Administrator for Insurance and Mitigation has resolved any appeals resulting from this notification.</P>
                <P>
                    The modified flood hazard determinations are made pursuant to section 206 of the Flood Disaster Protection Act of 1973, 42 U.S.C. 4105, and are in accordance with the National Flood Insurance Act of 1968, 42 U.S.C. 4001 
                    <E T="03">et seq.,</E>
                     and with 44 CFR part 65. The currently effective community number is shown and must be used for all new policies and renewals.
                </P>
                <P>The new or modified flood hazard information is the basis for the floodplain management measures that the community is required either to adopt or to show evidence of being already in effect in order to remain qualified for participation in the National Flood Insurance Program (NFIP).</P>
                <P>This new or modified flood hazard information, together with the floodplain management criteria required by 44 CFR 60.3, are the minimum that are required. They should not be construed to mean that the community must change any existing ordinances that are more stringent in their floodplain management requirements. The community may at any time enact stricter requirements of its own or pursuant to policies established by other Federal, State, or regional entities.</P>
                <P>This new or modified flood hazard determinations are used to meet the floodplain management requirements of the NFIP. The changes in flood hazard determinations are in accordance with 44 CFR 65.4.</P>
                <P>
                    Interested lessees and owners of real property are encouraged to review the final flood hazard information available at the address cited below for each community or online through the FEMA Map Service Center at

                     The Nonprofit Security Grant Program provides funding support for security related enhancements to nonprofit organizations that are at high risk of a terrorist or other extremist attack. The program seeks to integrate the preparedness activities of nonprofit organizations that are at high risk of a terrorist or other extremist attack with broader State and local preparedness efforts. The NSGP Investment Justification summarizes the nonprofit organization's mission, vulnerability assessment, and proposed project(s) details.

                <P>The Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 U.S.C. 5121-5207 (the Stafford Act), authorizes grants to assist State, local, Tribal, and territorial governments and certain private nonprofit entities with the response to and recovery from disasters following Presidentially declared major disasters and emergencies. 44 CFR part 206 specifies the information collections necessary to facilitate the provision of assistance under the PA Program. 44 CFR 206.202 describes the general application procedures for the PA Program. FEMA revised FEMA Form FF-104-FY-21-238, Pre-Approval Request to support survivors in non-congregate shelters and it was approved by the Office of Management and Budget (OMB) under an emergency request.</P>

                    <E T="04">Federal Register</E>
                     on Jan. 31, 2024, at 89 FR 6123 with a 60-day public comment period. FEMA received ten public comments. Two public comments were not relevant to this collection. Five State agencies (Florida, Iowa, Ohio, Missouri and South Dakota) provided detailed comments and proposed revisions. After public comment, language was refined to enhance the customer experience and understanding of the question. Policy related suggestions were referred to the policy team for review and consideration.
                </P>
                <P>Three individuals provided detailed comments and proposed revisions. Some comments were not germane to the collection. Other comments proposing elimination of questions were reviewed and accepted as the information is not necessary and removal reduced the burden on the applicant. The purpose of this notice is to inform the public that FEMA will submit the information collection abstracted below to the Office of Management and Budget for review and clearance.</P>

                     This information collection provides disaster survivors the opportunity to request approval of late applications, continued temporary housing assistance, request advance disaster assistance, stop payments not received in order to be reissued funds, and to appeal program decisions. This collection also allows for the establishment of an annual agreement between FEMA and States, Territories, and Tribal Governments regarding how the Other Needs Assistance provision of IHP will be administered: by FEMA, by the State, Territory, or Tribal Government, or jointly. This collection allows survivors to provide additional information after the initial disaster assistance registration period in support of their applications for assistance from FEMA's IHP. If the information in this collection is not collected, a delay in assistance provided to disaster survivors would occur.

                <P>
                    FEMA proposes to make flood hazard determinations for each community listed below, in accordance with section 110 of the Flood Disaster Protection Act of 1973, 42 U.S.C. 4104, and 44 CFR 67.4(a).
                    <PRTPAGE P="42896"/>
                </P>
                <P>These proposed flood hazard determinations, together with the floodplain management criteria required by 44 CFR 60.3, are the minimum that are required. They should not be construed to mean that the community must change any existing ordinances that are more stringent in their floodplain management requirements. The community may at any time enact stricter requirements of its own or pursuant to policies established by other Federal, State, or regional entities. These flood hazard determinations are used to meet the floodplain management requirements of the NFIP.</P>
                <P>The communities affected by the flood hazard determinations are provided in the tables below. Any request for reconsideration of the revised flood hazard information shown on the Preliminary FIRM and FIS report that satisfies the data requirements outlined in 44 CFR 67.6(b) is considered an appeal. Comments unrelated to the flood hazard determinations also will be considered before the FIRM and FIS report become effective.</P>
                <P>
                    Use of a Scientific Resolution Panel (SRP) is available to communities in support of the appeal resolution process. SRPs are independent panels of experts in hydrology, hydraulics, and other pertinent sciences established to review conflicting scientific and technical data and provide recommendations for resolution. Use of the SRP only may be exercised after FEMA and local communities have been engaged in a collaborative consultation process for at least 60 days without a mutually acceptable resolution of an appeal. Additional information regarding the SRP process can be found online at 
                    <E T="03">https://www.floodsrp.org/pdfs/srp_overview.pdf.</E>
                </P>
                <P>
                    The watersheds and/or communities affected are listed in the tables below. The Preliminary FIRM, and where applicable, FIS report for each community are available for inspection at both the online location 
                    <E T="03">https://hazards.fema.gov/femaportal/prelimdownload</E>
                     and the respective Community Map Repository address listed in the tables. For communities with multiple ongoing Preliminary studies, the studies can be identified by the unique project number and Preliminary FIRM date listed in the tables.

                </P>
                <P>The Committee will also meet in a closed session from 9 a.m. to 12 p.m. EDT to participate in an operational discussion that will address areas of critical cybersecurity vulnerabilities and priorities for CISA.

                     The form is used when an authorized noncriminal justice agency requests that the CJIS Division complete a Biographic Verification. Title 28, Code of Federal Regulations (CFR), Section 0.85 (j) sets forth the Attorney General's delegation to the FBI to implement the exchange of identity history information for noncriminal justice purposes. Additionally, 28 CFR 20.33 (a)(3) and 50.12 both further explain the dissemination of identity history information for noncriminal justice purposes. The FBI's Criminal Justice Information Services (CJIS) Division currently offers a Biographic Verification Service to noncriminal justice agencies as a way to obtain adjudicated criminal history information in cases where the required fingerprint image quality could not be achieved after two attempts for a fingerprint-based search. The service was implemented to ensure that individuals with poor quality fingerprints not be denied benefits, licensing, or employment opportunities due to non-discernible fingerprints. The information collected on the CJIS Biographic Verification Request form is required to ensure the agency requesting the service has the authority to request and obtain the results and to verify fingerprints were submitted and rejected twice for the individual of the request.

                <P>
                    (a) How made and addressed. You may make a request for records of the Department of Justice by writing directly to the Department component that maintains those records. You may find the Department's “Freedom of Information Act Reference Guide”—which is available electronically at the Department's World Wide website, and is available in paper form as well—helpful in making your request. For additional information about the FOIA, you may refer directly to the statute. If you are making a request for records about yourself, see § 16.41(d) for additional requirements. If you are making a request for records about another individual, either a written authorization signed by that individual permitting disclosure of those records to you or proof that that individual is deceased (for example, a copy of a death certificate or an obituary) will help the processing of your request. Your request should be sent to the component's FOIA office at the address listed in appendix I to part 16. In most cases, your FOIA request should be sent to a component's central FOIA office. For records held by a field office of the FBI or the Immigration and Naturalization Service (INS), however, you must write directly to that FBI or INS field office address, which can be found in most telephone books or by calling the component's central FOIA office. (The functions of each component are summarized in part 0 of this title and in the description of the Department and its components in the “United States Government Manual,” which is issued annually and is available in most libraries, as well as for sale from the Government Printing Office's Superintendent of Documents. This manual also can be accessed electronically at the Government Printing Office's World Wide website (which can be found at 
                    <E T="03">http://www.access.gpo.gov/su_docs</E>
                    ).) If you cannot determine where within the Department to send your request, you may send it to the FOIA/PA Mail Referral Unit, Justice Management Division, U.S. Department of Justice, 950 Pennsylvania Avenue NW, Washington, DC 20530-0001. That office will forward your request to the component(s) it believes most likely to have the records that you want. Your request will be considered received as of the date it is received by the proper component's FOIA office. For the quickest possible handling, you should mark both your request letter and the envelope “Freedom of Information Act Request.”
                </P>
                <P>
                    (b) Description of records sought. You must describe the records that you seek in enough detail to enable Department personnel to locate them with a 
                    <PRTPAGE P="42902"/>
                    reasonable amount of effort. Whenever possible, your request should include specific information about each record sought, such as the date, title or name, author, recipient, and subject matter of the record. In addition, if you want records about a court case, you should provide the title of the case, the court in which the case was filed, and the nature of the case. If known, you should include any file designations or descriptions for the records that you want. As a general rule, the more specific you are about the records or type of records that you want, the more likely the Department will be able to locate those records in response to your request. If a component determines that your request does not reasonably describe records, it shall tell you either what additional information is needed or why your request is otherwise insufficient. The component also shall give you an opportunity to discuss your request so that you may modify it to meet the requirements of this section. If your request does not reasonably describe the records you seek, the agency's response to your request may be delayed.

                <P>(c) Agreement to pay fees. If you make a FOIA request, it shall be considered an agreement by you to pay all applicable fees charged under § 16.11, up to $25.00, unless you seek a waiver of fees. The component responsible for responding to your request ordinarily will confirm this agreement in an acknowledgement letter. When making a request, you may specify a willingness to pay a greater or lesser amount.</P>

When registrants or other authorized individuals request information from or copies of SSS records they must provide on forms or letters certain information about the registrant and the nature of the request. Requesters use NA Form 13172, Selective Service Record Request to obtain information from SSS records stored at NARA facilities.

                <P>The Amundsen-Scott South Pole station is one of three year-round stations operated by the National Science Foundation (NSF) as outlined in Presidential Memorandum 6646. The South Pole is a unique research site that supports projects ranging from cosmic observations to seismic and atmospheric studies. The South Pole Station begins austral summer operations in October of each year. The station typically remains in summer operating mode until early February, at which point the eight-month long winter season begins.</P>
                <P>Amundsen-Scott South Pole Station sits at the Earth's axis on a shifting continental ice sheet several miles thick. At an elevation of 2,835 meters (9,300 feet), the South Pole has an average monthly temperature in the austral summer of −28 °C (−18 °F); in the austral winter, the average monthly temperature is −60 °C (−76 °F).</P>
                <P>
                    The NSF Office of Polar Programs has identified the need for a South Pole Station Master Plan. The master plan looks at future infrastructure needs to support groundbreaking science at the South Pole, as well as phasing for implementation. NSF will consider input from the community before completing the final plan later this year. The final SPSMP will be posted online at 
                    <E T="03">www.usap.gov</E>
                     along with the existing Master Plans for NSF McMurdo Station and NSF Palmer Station.

                <P>
                    Constellation Energy Generation, LLC (Constellation) is the holder of Renewed Facility Operating License Nos. NPF-39 and NPF-85, which authorize operation of the Limerick Generating Station (LGS) Units 1 and 2 in Limerick, Pennsylvania, pursuant to Part 50 of Title 10 of the 
                    <E T="03">Code of Federal Regulations</E>
                     (10 CFR), “Domestic Licensing of Production and Utilization Facilities.” The licenses provide, among other things, that the facility is subject to all rules, regulations, and orders of the U.S. Nuclear Regulatory Commission (NRC) now or hereafter in effect.
                </P>
                <P>Consistent with 10 CFR part 72, subpart K, “General License for Storage of Spent Fuel at Power Reactor Sites,” a general license is issued for the storage of spent fuel in an Independent Spent Fuel Storage Installation (ISFSI) at power reactor sites to persons authorized to possess or operate nuclear power reactors under 10 CFR part 50. Constellation is authorized to operate nuclear power reactors under 10 CFR part 50 and holds a 10 CFR part 72 general license for storage of spent fuel at the LGS ISFSI. Under the terms of the general license, Constellation stores spent fuel at its LGS ISFSI using the HI-STORM Flood/Wind (FW) Multi-Purpose Canister (MPC) Storage System in accordance with Certificate of Compliance (CoC) No. 1032, Amendment No. 1, Revision No. 1.</P>
                <HD SOURCE="HD1">II. Request/Action</HD>
                <P>
                    By a letter dated April 5, 2024 (Agencywide Documents Access and Management System [ADAMS] Accession No. ML24096A137), Constellation requested an exemption from the requirements of 10 CFR 72.212(a)(2), 72.212(b)(3), 72.212(b)(5)(i), 72.212(b)(11), and 72.214 that require the LGS to comply with the terms, conditions, and specifications of the CoC No. 1032, Amendment No. 1, Revision No. 1 (ML15152A358). If approved, Constellation's exemption request would accordingly allow the LGS to maintain three loaded and to load five MPCs with continuous basket shims (CBS) (
                    <E T="03">i.e.,</E>
                     MPC-89-CBS) in the HI-STORM FW MPC Storage System, and thus, to maintain and load the systems in a storage condition where the terms, conditions, and specifications in the CoC No. 1032, Amendment No. 1, Revision No. 1, are not met.
                </P>
                <P>Constellation currently uses the HI-STORM FW MPC Storage System under CoC No. 1032, Amendment No. 1, Revision No. 1, for dry storage of spent nuclear fuel in MPC-89 at the LGS ISFSI. Holtec International (Holtec), the designer and manufacturer of the HI-STORM FW MPC Storage System, developed a variant of the design with CBS for the MPC-89 known as MPC-89-CBS. Holtec performed a non-mechanistic tip-over analysis with favorable results and implemented the CBS variant design under the provisions of 10 CFR 72.48, “Changes, tests, and experiments,” which allows licensees to make changes to cask designs without a CoC amendment under certain conditions (listed in 10 CFR 72.48(c)). After evaluating the specific changes to the cask designs, the NRC determined that Holtec erred when it implemented the CBS variant design under 10 CFR 72.48, as this is not the type of change allowed without a CoC amendment. For this reason, the NRC issued three Severity Level IV violations to Holtec (ML24016A190).</P>
                <P>Prior to the issuance of the violations, Constellation had loaded three MPC-89-CBS in the HI-STORM FW MPC Storage System, which are safely in storage at the LGS ISFSI.</P>
                <P>
                    Constellation's near-term loading campaign for the LGS ISFSI include plans to load five MPC-89-CBS in the HI-STORM FW MPC Storage System beginning in August 2024. While Holtec was required to submit a CoC 
                    <PRTPAGE P="42906"/>
                    amendment to the NRC to seek approval of the CBS variant design, such a process will not be completed in time to inform decisions for this near-term loading campaign. Therefore, Constellation submitted this exemption request in order to allow for the continued storage of the three already loaded MPC-89-CBS, and future loading of five MPC-89-CBS beginning in August 2024 at the LGS ISFSI. This exemption is limited to the use of MPC-89-CBS in the HI-STORM FW MPC Storage System only for the three already loaded canisters and specific near-term planned loading of five new canisters using the MPC-89-CBS variant basket design.
                </P>
                <HD SOURCE="HD1">III. Discussion</HD>
                <P>Pursuant to 10 CFR 72.7, “Specific exemptions,” the Commission may, upon application by any interested person or upon its own initiative, grant such exemptions from the requirements of the regulations of 10 CFR part 72 as it determines are authorized by law and will not endanger life or property or the common defense and security and are otherwise in the public interest.</P>
                <HD SOURCE="HD2">A. The Exemption Is Authorized by Law</HD>
                <P>This exemption would allow Constellation to maintain three loaded and to load five MPC-89-CBS in the HI-STORM FW MPC Storage System at its LGS ISFSI in a storage condition where the terms, conditions, and specifications in the CoC No. 1032, Amendment No. 1, Revision No. 1, are not met. Constellation is requesting an exemption from the provisions in 10 CFR part 72 that require the licensee to comply with the terms, conditions, and specifications of the CoC for the approved cask model it uses. Section 72.7 allows the NRC to grant exemptions from the requirements of 10 CFR part 72. This authority to grant exemptions is consistent with the Atomic Energy Act of 1954, as amended, and is not otherwise inconsistent with the NRC's regulations or other applicable laws. Additionally, no other law prohibits the activities that would be authorized by the exemption. Therefore, the NRC concludes that there is no statutory prohibition on the issuance of the requested exemption, and the NRC is authorized to grant the exemption by law.</P>
                <HD SOURCE="HD2">B. The Exemption Will Not Endanger Life or Property or the Common Defense and Security</HD>
                <P>This exemption would allow Constellation to maintain three loaded and to load five MPC-89-CBS in the HI-STORM FW MPC Storage System at the LGS ISFSI in a storage condition where the terms, conditions, and specifications in the CoC No. 1032, Amendment No. 1, Revision No. 1, are not met. In support of its exemption request, Constellation asserts that issuance of the exemption would not endanger life or property because the administrative controls the applicant has in place prevent a tip-over or handling event, and that the containment boundary would be maintained in such an event. Constellation relies, in part, on the approach in the NRC's Safety Determination Memorandum (ML24018A085). The NRC issued this Safety Determination Memorandum to address whether, with respect to the enforcement action against Holtec regarding this violation, there was any need to take an immediate action for the cask systems that were already loaded with non-compliant basket designs. The Safety Determination Memorandum documents a risk-informed approach concluding that, during the design basis event of a non-mechanistic tip-over, the fuel in the basket in the MPC-89-CBS remains in a subcritical condition.</P>
                <P>Constellation also provided site-specific technical information, including information explaining why the use of the approach in the NRC's Safety Determination Memorandum is appropriate for determining the safe use of the CBS variant baskets at the LGS ISFSI. Specifically, Constellation described that the analysis of the tip-over design basis event that is relied upon in the NRC's Safety Determination Memorandum, which demonstrates that the MPC confinement barrier is maintained, is documented in the updated final safety analysis report (UFSAR) for the HI-STORM FW MPC Storage System CoC No. 1032, Amendment 1, Revision No. 1, that is used at the LGS site. Constellation also described its administrative controls for handling of the HI-STORM FW MPC Storage System at the LGS ISFSI to prevent a tip-over or handling event. Those controls include using single-failure-proof handling systems as defined in Section 5.1.6 of NUREG-0612, “Control of Heavy Loads at Nuclear Power Plants”. The LGS's UFSAR Section 9.1.5.4 indicates that the single failure proof design of the reactor enclosure crane conforms to NUREG-0554, “Single-Failure-Proof Cranes for Nuclear Power Plants”. Constellation referenced their “Rigging and Lifting Program”, “Control of Heavy Loads Program” and “Limerick Generating Station Rigging and Handling Heavy Loads” to further demonstrate that the LGS has applicable operational procedures in place to safely load, process, transfer and move the MPCs in accordance with the Technical Specifications in Appendix A of the CoC and the HI-STORM FW UFSAR.</P>
                <P>Additionally, Constellation provided specific information from the LGS's 72.212 Evaluation Report, Revision 3, indicating that during the design basis event of a non-mechanistic tip-over, the LGS's ISFSI would meet the requirements in 10 CFR 72.104, “Criteria for radioactive materials in effluents and direct radiation from an ISFSI or MRS,” and 72.106, “Controlled area of an ISFSI or MRS.” Specifically, Constellation described that, in the highly unlikely event of a tip-over, any potential fuel damage from a non-mechanistic tip-over event would be localized, the confinement barrier would be maintained, and the shielding material would remain intact. Coupled with the distance of the LGS ISFSI to the site area boundary, Constellation concluded that compliance with 72.104 and 72.106 is not impacted by approving this exemption request.</P>
                <P>The NRC staff reviewed the information provided by Constellation and concludes that issuance of the exemption would not endanger life or property because the administrative controls Constellation has in place at the LGS ISFSI sufficiently minimize the possibility of a tip-over or handling event, and that the containment boundary would be maintained in such an event. The staff confirmed that these administrative controls are documented in the technical specifications and UFSAR for the HI-STORM FW MPC Storage System CoC No. 1032, Amendment 1, Revision No. 1, that is used at the LGS site. In addition, the staff confirmed that the information provided by Constellation regarding the LGS's 72.212 Evaluation Report, Revision 3, demonstrates that the consequences of normal and accident conditions would be within the regulatory limits of the 10 CFR 72.104 and 10 CFR 72.106. The staff also determined that the requested exemption is not related to any aspect of the physical security or defense of the LGS ISFSI; therefore, granting the exemption would not result in any potential impacts to common defense and security.</P>
                <P>
                    For these reasons, the NRC staff has determined that under the requested exemption, the storage system will continue to meet the safety requirements of 10 CFR part 72 and the offsite dose limits of 10 CFR part 20 and, therefore, will not endanger life or 
                    <PRTPAGE P="42907"/>
                    property or the common defense and security.
                </P>
                <HD SOURCE="HD2">C. The Exemption Is Otherwise in the Public Interest</HD>
                <P>The proposed exemption would allow the three already loaded MPC-89-CBS in the HI-STORM FW MPC Storage System to remain in storage at the LGS ISFSI and allow Constellation to load five MPC-89-CBS in the HI-STORM FW MPC Storage System beginning in August 2024 at the LGS ISFSI, even though the CBS variant basket design is not part of the approved CoC No. 1032, Amendment No. 1, Revision No. 1. According to Constellation, the exemption is in the public interest because unloading fuel from already loaded canisters and not being able to load fuel into dry storage in future loading campaigns would impact Constellation's ability to offload fuel from the LGS reactor units, consequently impacting continued safe reactor operation. The reflooding of the MPCs, removal of fuel assemblies, and replacement into a different MPC would result in additional doses and handling operations with no added safety benefit. In addition, future loading campaigns would need to be delayed until older design canisters can be fabricated and delivered to the site.</P>
                <P>Constellation stated that to unload already loaded MPC-89-CBS or delay the future loading campaigns would impact the ability to effectively manage the margin to full core discharge capacity in the LGS Units 1 and 2 spent fuel pools. The low spent fuel pool capacity would make it difficult to refuel and present potential risks to fuel handling operations during pre- and post-outage. In addition, a crowded spent fuel pool would challenge the decay heat removal demand of the pool and increase the likelihood of a loss of fuel pool cooling event and a fuel handling accident. Furthermore, the LGS planned the cask loading campaigns years in advance based on availability of the specialized workforce and equipment that is shared throughout the Constellation fleet. These specialty resources support competing priorities including refueling outages, loading campaigns, fuel pool cleanouts, fuel inspections, fuel handing equipment upgrade and maintenance, fuel sipping, new fuel receipt, and crane maintenance and upgrades. Any delays would have a cascading impact on other scheduled specialized activities.</P>
                <P>For the reasons described by Constellation in the exemption request, the NRC agrees that it is in the public interest to grant the exemption. If the exemption is not granted, in order to comply with the CoC, Constellation would have to unload MPC-89-CBS from the HI-STORM FW MPC Storage System at the LGS ISFSI and reload into the older design MPC-89 to restore compliance with terms, conditions, and specifications of the CoC. This would subject onsite personnel to additional radiation exposure, increase the risk of a possible fuel handling accident, and increase the risk of a possible heavy load handling accident. Furthermore, the removed spent fuel would need to be placed in the spent fuel pool until it can be loaded into another storage cask or remain in the spent fuel pool if it is not permitted to be loaded into casks for future loading campaigns. As described by Constellation, this scenario would affect Constellation's ability to effectively manage the spent pool capacity and reactor fuel offloading at the LGS. In addition, the rescheduling of the specialized resources for the future loading campaigns would impact the operations of the LGS and other Constellation sites.</P>
                <P>Therefore, the staff concludes that approving the exemption is in the public interest.</P>
                <HD SOURCE="HD3">Environmental Consideration</HD>
                <P>The NRC staff also considered whether there would be any significant environmental impacts associated with the exemption. For this proposed action, the NRC staff performed an environmental assessment pursuant to 10 CFR 51.30. The environmental assessment concluded that the proposed action would not significantly impact the quality of the human environment. The NRC staff concluded that the proposed action would not result in any changes in the types or amounts of any radiological or non-radiological effluents that may be released offsite, and there would be no significant increase in occupational or public radiation exposure because of the proposed action. The environmental assessment and the finding of no significant impact was published on May 8, 2024 (89 FR 38921).</P>
                <HD SOURCE="HD1">IV. Conclusion</HD>
                <P>Based on these considerations, the NRC has determined that, pursuant to 10 CFR 72.7, the exemption is authorized by law, will not endanger life or property or the common defense and security, and is otherwise in the public interest. Therefore, the NRC grants Constellation an exemption from the requirements of §§ 72.212(a)(2), 72.212(b)(3), 72.212(b)(5)(i), 72.212(b)(11), and 72.214 with respect to the ongoing storage of three MPC-89-CBS in the HI-STORM FW MPC Storage System and a future loading in the HI-STORM FW MPC Storage System of five new MPC-89-CBS beginning in August 2024.</P>
                <P>This exemption is effective upon issuance.</P>

Training/Internship Placement Plans are to be completed by designated program sponsors. A Training/Internship Placement Plan is required for each trainee or intern participant. It will set forth the training or internship program to be followed, methods of supervision, the skills the trainee or intern will obtain, and trainee or intern remuneration. The plan must be signed by the trainee or intern, sponsor, and the third-party placement organization, if a third-party organization is used in the conduct of the training or internship. Upon request, trainees or interns must present a fully executed Training/Internship Placement Plan on Form DS-7002 to any Consular Official interviewing them in connection with the issuance of J-1 visas.</P>

                <HD SOURCE="HD1">II. Background</HD>
                <P>Under 49 U.S.C. 31136(e) and 31315(b), FMCSA may grant an exemption from the FMCSRs for no longer than a 5-year period if it finds such exemption would likely achieve a level of safety that is equivalent to, or greater than, the level that would be achieved absent such exemption. The statutes also allow the Agency to renew exemptions at the end of the 5-year period. FMCSA grants medical exemptions from the FMCSRs for a 2-year period to align with the maximum duration of a driver's medical certification.</P>
                <P>The 10 individuals listed in this notice have requested an exemption from the hearing requirement in 49 CFR 391.41(b)(11). Accordingly, the Agency will evaluate the qualifications of each applicant to determine whether granting the exemption will achieve the required level of safety mandated by statute.</P>
                <P>The physical qualification standard for drivers regarding hearing found in § 391.41(b)(11) states that a person is physically qualified to drive a CMV if that person first perceives a forced whispered voice in the better ear at not less than 5 feet with or without the use of a hearing aid or, if tested by use of an audiometric device, does not have an average hearing loss in the better ear greater than 40 decibels at 500 Hz, 1,000 Hz, and 2,000 Hz with or without a hearing aid when the audiometric device is calibrated to American National Standard (formerly ASA Standard) Z24.5—1951.</P>
                <P>This standard was adopted in 1970 and was revised in 1971 to allow drivers to be qualified under this standard while wearing a hearing aid, (35 FR 6458, 6463 (Apr. 22, 1970) and 36 FR 12857 (July 8, 1971), respectively).</P>
                <P>On February 1, 2013, FMCSA announced in a Notice of Final Disposition titled, “Qualification of Drivers; Application for Exemptions; National Association of the Deaf,” (78 FR 7479), its decision to grant requests from 40 individuals for exemptions from the Agency's physical qualification standard concerning hearing for interstate CMV drivers. Since that time the Agency has published additional notices granting requests from hard of hearing and deaf individuals for exemptions from the Agency's physical qualification standard concerning hearing for interstate CMV drivers.</P>

                     Interested parties may comment on the effect this action may have on U.S. vessel builders or businesses in the U.S. that use U.S.-flag vessels. If MARAD determines, in accordance with 46 U.S.C. 12121 and MARAD's regulations at 46 CFR part 388, that the employment of the vessel in the coastwise trade to carry no more than 12 passengers will have an unduly adverse effect on a U.S.-vessel builder or a business that uses U.S.-flag vessels in that business, MARAD will not issue an approval of the vessel's coastwise endorsement eligibility. Comments should refer to the vessel name, state the commenter's interest in the application, and address the eligibility criteria given in section 388.4 of MARAD's regulations at 46 CFR part 388.

                     Under 12 CFR 1.3(h)(2), a national bank may request an OCC determination that it may invest in an entity that is exempt from registration under section 3(c)(1) of the Investment Company Act of 1940 
                    <SU>1</SU>
                    <FTREF/>
                     if the portfolio of the entity consists exclusively of assets that a national bank may purchase and sell for its own account. The OCC uses the information contained in the request as a basis for ensuring that the bank's investment is consistent with its investment authority under applicable law and does not pose unacceptable risk. Under 12 CFR 1.7(b), a national bank may request OCC approval to extend the five-year holding period for securities held in satisfaction of debts previously contracted for up to an additional five years. In its request, the bank must provide a clearly convincing demonstration of why the additional holding period is needed. The OCC uses the information in the request to ensure, on a case-by-case basis, that the bank's purpose in retaining the securities is not speculative and that the bank's reasons for requesting the extension are adequate. The OCC also uses the information to evaluate the risks to the bank in extending the holding period, including potential effects on the bank's safety and soundness.

                     The information collection is contained within the regulations issued pursuant to the GSA, which require government securities brokers and dealers to make and keep certain records concerning their business activities and their holdings of government securities, to submit financial reports, and to make certain disclosures to investors. The regulations also require depository institutions to keep certain records of non-fiduciary custodial holdings of government securities. The regulations and associated information collection are fundamental to customer protection and dealer financial responsibility.

The EPA is also finalizing amendments to the NSPS for equipment leaks of volatile organic compounds (VOC) in SOCMI based on its reconsideration of certain issues raised in an administrative petition for reconsideration. Furthermore, the EPA is finalizing emission standards for ethylene oxide (EtO) emissions and chloroprene emissions after considering the results of a risk assessment for the HON and for Neoprene Production processes subject to the P&amp;R I NESHAP, and is finalizing a fenceline monitoring work practice standard for certain hazardous air pollutants (HAP). Lastly, the EPA is finalizing the removal of exemptions from standards for periods of startup, shutdown, and malfunction (SSM), adding work practice standards for such periods where appropriate, finalizing standards for previously unregulated HAP, and adding provisions for electronic reporting of performance test reports and periodic reports.</P>

                         On April 25, 2023, the EPA proposed amendments to the NSPS that apply to the SOCMI, and amendments to the HON and P&amp;R I and P&amp;R II NESHAP. In this action, we are finalizing decisions and revisions for the rule. We summarize some of the more significant comments we timely received regarding the proposed rule and provide our responses in this preamble. A summary of all other public comments on the proposal and the EPA's responses to those comments is available in the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         Docket ID No. EPA-HQ-OAR-2022-0730. A “track changes” version of the regulatory language that incorporates the changes in this action is available in the docket.

                    <P>
                        The source categories that are the subject of this final action are the SOCMI and various polymers and resins manufacturing source categories. The SOCMI source category includes chemical manufacturing processes producing commodity chemicals while the polymers and resins manufacturing source categories covered in this action include elastomers production processes and resin production processes that use epichlorohydrin feedstocks (see sections I.B and II.B of this preamble for detailed information about these source categories). The EPA has previously promulgated maximum achievable control technology (MACT) standards for certain processes in the SOCMI source category in the HON rulemaking at 40 Code of Federal Regulations (CFR) part 63, subparts F, G, and H. In 1994, the EPA finalized MACT standards in subparts F, G, and 
                        <PRTPAGE P="42934"/>
                        H for SOCMI processes (59 FR 19454),
                        <SU>1</SU>
                        <FTREF/>
                         and the Agency completed a residual risk and technology review (RTR) for these NESHAP in 2006 (71 FR 76603). In 1995, the EPA finalized MACT standards in the P&amp;R II NESHAP (40 CFR part 63, subpart W) for epoxy resin and non-nylon polyamide resin manufacturing processes (60 FR 12670), and the Agency completed a residual RTR for these standards in 2008 (73 FR 76220). In 1996, the EPA finalized MACT standards in the P&amp;R I NESHAP (40 CFR part 63, subpart U) for various elastomer manufacturing processes (61 FR 46906), and the Agency completed residual RTRs for these standards in 2008 and 2011 (73 FR 76220 and 76 FR 22566).
                    </P>
                    <FTNT>
                        <P>
                            <SU>1</SU>
                             Around the same time, the EPA set MACT standards for equipment leaks from certain non-SOCMI processes at chemical plants regulated under 40 CFR part 63, subpart I (59 FR 19587).
                        </P>
                    </FTNT>
                    <P>The EPA has also promulgated NSPS for certain processes in the SOCMI source category. In 1983, the EPA finalized NSPS (40 CFR part 60, subpart VV) for equipment leaks of VOC in SOCMI (48 FR 48328). In 1990, the EPA finalized NSPS (40 CFR part 60, subparts III and NNN) for VOC from air oxidation unit processes and distillation operations (55 FR 26912 and 55 FR 26931). In 1993, the EPA finalized NSPS (40 CFR part 60, subpart RRR) for VOC from reactor processes (58 FR 45948). In 2007, the EPA promulgated NSPS (40 CFR part 60, subpart VVa) for VOC from certain equipment leaks (72 FR 64883), which reflect the EPA's review and revision of the standards in 40 CFR part 60, subpart VV.</P>
                    <P>The statutory authority for this action is sections 111, 112, 301(a)(1), and 307(d)(7)(B) of the CAA. Section 111(b)(1)(B) of the CAA requires the EPA to promulgate standards of performance for new sources in any category of stationary sources that the Administrator has listed pursuant to 111(b)(1)(A). Section 111(a)(1) of the CAA provides that these performance standards are to “reflect[ ] the degree of emission limitation achievable through the application of the best system of emission reduction which (taking into account the cost of achieving such reduction and any nonair quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.” We refer to this level of control as the best system of emissions reduction or “BSER.” Section 111(b)(1)(B) of the CAA requires the EPA to “at least every 8 years, review and, if appropriate, revise” the NSPS.</P>
                    <P>For NESHAP, CAA section 112(d)(2) requires the EPA to establish MACT standards for listed categories of major sources of HAP. Section 112(d)(6) of the CAA requires the EPA to review standards promulgated under CAA section 112, and revise them “as necessary (taking into account developments in practices, processes, and control technologies),” no less often than every eight years following promulgation of those standards. This is referred to as a “technology review” and is required for all standards established under CAA section 112. Section 112(f) of the CAA requires the EPA to assess the risk to public health remaining after the implementation of MACT emission standards promulgated under CAA section 112(d)(2). If the MACT standards for a source category do not provide “an ample margin of safety to protect public health,” the EPA must also promulgate health-based standards for that source category to further reduce risk from HAP emissions.</P>
                    <P>Section 301(a)(1) of the CAA authorizes the Administrator to prescribe such regulations as are necessary to carry out his functions under the CAA. Section 307(d)(7)(B) of the CAA requires the reconsideration of a rule only if the person raising an objection to the rule can demonstrate that it was impracticable to raise such objection during the period for public comment or if the grounds for the objection arose after the comment period (but within the time specified for judicial review), and if the objection is of central relevance to the outcome of the rule.</P>
                    <P>
                        The final new NSPS for SOCMI equipment leaks, air oxidation unit processes, distillation operations, and reactor processes (
                        <E T="03">i.e.,</E>
                         NSPS subparts VVb, IIIa, NNNa, and RRRa, respectively) are based on the Agency's review of the current NSPS (subparts VVa, III, NNN, and RRR) pursuant to CAA section 111(b)(1)(B), which requires that the EPA review the NSPS every eight years and, if appropriate, revise them. In addition, the EPA is finalizing amendments to the NSPS for equipment leaks of VOC in SOCMI based on its reconsideration of certain aspects of subparts VV and VVa that were raised in an administrative petition which the Agency granted pursuant to section 307(d)(7)(B) of the CAA. The final amendments to the HON (NESHAP subparts F, G, H, and I), the P&amp;R I NESHAP (NESHAP subpart U), and the P&amp;R II NESHAP (NESHAP subpart W) are based on the Agency's review of the current NESHAP (subparts F, G, H, I, U, and W) pursuant to CAA sections 112(d) and (f).
                    </P>
                    <P>
                        Due to the development of the EPA's Integrated Risk Information System (IRIS) inhalation unit risk estimate (URE) for chloroprene in 2010, the EPA conducted a second CAA section 112(f) risk review for the SOCMI source category and Neoprene Production source category. In the first step of the CAA section 112(f)(2) determination of risk acceptability for this rulemaking, the use of the 2010 chloroprene risk value resulted in the EPA identifying unacceptable cancer risk driven by chloroprene emissions from the sole affected source producing neoprene subject to the P&amp;R I NESHAP.
                        <SU>2</SU>
                        <FTREF/>
                         Consequently, the final amendments to the P&amp;R I NESHAP address the EPA review of additional control technologies, beyond those analyzed in the technology review conducted for the P&amp;R I source category, to address the unacceptable risk and achieve an ample margin of safety to protect public health at that affected source.
                    </P>

                        <P>
                            <SU>2</SU>
                             As discussed in section III.B of the proposal preamble (see 88 FR 25080, April 25, 2023), chloroprene emissions from HON processes do not on their own present unacceptable cancer risk from the SOCMI source category.
                        </P>
                    </FTNT>
                    <P>Additionally, in 2016, the EPA updated the IRIS inhalation URE for EtO. In the first step of the CAA section 112(f)(2) determination of risk acceptability for this rulemaking, the use of the updated 2016 EtO risk value resulted in the EPA identifying unacceptable cancer risk driven by EtO emissions from HON processes. Consequently, the final amendments to the HON also address the EPA review of additional control technologies, beyond those analyzed in the technology review conducted for the SOCMI source category, to address the unacceptable risk and achieve an ample margin of safety to protect public health at SOCMI and P&amp;R I affected sources.</P>

We are finalizing a mass-based exemption criterion of 0.001 lb/hr TOC (for which emission controls are not required) in new NSPS subparts IIIa and NNNa. We are also not including a relief valve discharge exemption in the definition of “vent stream” in new NSPS subparts IIIa, NNNa, and RRRa; instead, any relief valve discharge to the atmosphere of a vent stream is a violation of the emissions standard. In addition, we are finalizing in new NSPS subparts IIIa, NNNa, and RRRa the same work practice standards for maintenance vents that we are finalizing for HON process vents, and the same monitoring requirements that we are finalizing for HON process vents for adsorbers that cannot be regenerated and regenerative adsorbers that are regenerated offsite (see sections III.B.2 and IV.B of this preamble).

                         In the development of NESHAP for this source category, the EPA considered emission sources associated with: equipment leaks (including leaks from heat exchange systems), process vents, transfer racks, storage vessels, and wastewater collection and treatment systems. The elastomer production source categories in the P&amp;R I NESHAP and resins produced with epichlorohydrin feedstock in the P&amp;R II NESHAP have many similar emission sources with SOCMI sources and are discussed further in section II.B of this preamble.

                    <HD SOURCE="HD3">1. NESHAP</HD>
                    <P>
                        The statutory authority for this action related to NESHAP is provided by sections 112 and 301 of the CAA, as amended (42 U.S.C. 7401 
                        <E T="03">et seq.</E>
                        ). Section 112 of the CAA establishes a two-stage regulatory process to develop standards for emissions of HAP from stationary sources. “Major sources” are those that emit, or have the potential to emit, any single HAP at a rate of 10 tpy or more, or 25 tpy or more of any combination of HAP. For major sources, 
                        <PRTPAGE P="42940"/>
                        these standards are commonly referred to as MACT standards and must reflect the maximum degree of emission reductions of HAP achievable (after considering cost, energy requirements, and non-air quality health and environmental impacts). In developing MACT standards, CAA section 112(d)(2) directs the EPA to consider the application of measures, processes, methods, systems, or techniques, including, but not limited to, those that reduce the volume of or eliminate HAP emissions through process changes, substitution of materials, or other modifications; enclose systems or processes to eliminate emissions; collect, capture, or treat HAP when released from a process, stack, storage, or fugitive emissions point; are design, equipment, work practice, or operational standards; or any combination of the above. The MACT standards may take the form of design, equipment, work practice or operational standards where the EPA first determines either that (1) a pollutant cannot be emitted through a conveyance designed and constructed to emit or capture the pollutant, or that any requirement for, or use of, such a conveyance would be inconsistent with law; or (2) the application of measurement methodology to a particular class of sources is not practicable due to technological and economic limitations. CAA section 112(h)(1)-(2).
                    </P>
                    <P>For these MACT standards, the statute specifies certain minimum stringency requirements, which are referred to as MACT floor requirements, and which may not be based on cost considerations. See CAA section 112(d)(3). For new sources, the MACT floor cannot be less stringent than the emission control achieved in practice by the best-controlled similar source. The MACT standards for existing sources can be less stringent than floors for new sources, but they cannot be less stringent than the average emission limitation achieved by the best-performing 12 percent of existing sources in the category or subcategory (or the best-performing five sources for categories or subcategories with fewer than 30 sources). In developing MACT standards, we must also consider control options that are more stringent than the floor under CAA section 112(d)(2). We may establish standards more stringent than the floor, based on the consideration of the cost of achieving the emissions reductions, any non-air quality health and environmental impacts, and energy requirements.</P>
                    <P>
                        In the second stage of the regulatory process, the CAA requires the EPA to undertake two different analyses, which we refer to as the technology review and the residual risk review. Under the technology review, we must review the technology-based standards and revise them “as necessary (taking into account developments in practices, processes, and control technologies)” no less frequently than every 8 years, pursuant to CAA section 112(d)(6). In conducting this review, the EPA is not required to recalculate the MACT floors that were established in earlier rulemakings.

The EPA is required to address regulatory gaps, such as missing standards for listed air toxics known to be emitted from the source category, and any new MACT standards must be established under CAA sections 112(d)(2) and (3), or, in specific circumstances, CAA sections 112(d)(4) or (h).

                         955 F.3d 1088 (D.C. Cir. 2020). Under the residual risk review, we must evaluate the risk to public health remaining after application of the technology-based standards and revise the standards, if necessary, to provide an ample margin of safety to protect public health or to prevent, taking into consideration costs, energy, safety, and other relevant factors, an adverse environmental effect. The residual risk review is required within 8 years after promulgation of the MACT standards, pursuant to CAA section 112(f). In conducting the residual risk review, if the EPA determines that the current standards provide an ample margin of safety to protect public health, it is not necessary to revise the MACT standards pursuant to CAA section 112(f).

                        The EPA conducted a combined RTR for the HON in 2006, concluding that there was no need to revise the HON under the provisions of either CAA section 112(f) or 112(d)(6). As part of the residual risk review, the EPA conducted a risk assessment and, based on the results of the risk assessment, determined that the then-current level of control called for by the existing MACT standards both reduced HAP emissions to levels that presented an acceptable level of risk and provided an ample margin of safety to protect public health (see 71 FR 76603, December 21, 2006 for additional details). In 2008, the EPA conducted a combined RTR for four of the P&amp;R I source categories (including the Polysulfide Rubber Production, Ethylene-Propylene Elastomers Production, Butyl Rubber Production, and Neoprene Production source categories) and all P&amp;R II source categories (Epoxy Resins Production and Non-Nylon Polyamides Production source categories). In 2011, the EPA completed the combined RTR for the remaining five P&amp;R I source categories (Epichlorohydrin Elastomers Production, Hypalon

The EPA concluded in these actions that there was no need to revise standards for any of the nine P&amp;R I source categories and two P&amp;R II source categories under the provisions of either CAA section 112(f) or 112(d)(6) (see 73 FR 76220, December 16, 2008 and 77 FR 22566, April 21, 2011 for additional details).

                        This action constitutes another CAA section 112(d)(6) technology review for the HON and the P&amp;R I and P&amp;R II NESHAP. This action also constitutes an updated CAA section 112(f) risk review based on new information for the HON and for affected sources producing neoprene subject to the P&amp;R I NESHAP. We note that although there is no statutory CAA obligation under CAA section 112(f) for the EPA to conduct a second residual risk review of the HON or of standards for affected sources producing neoprene subject to the P&amp;R I NESHAP, the EPA retains discretion to revisit its residual risk reviews where the Agency deems that to be warranted.

                        Here, the specific changes to health information related to certain pollutants emitted by these unique categories led us to determine that it is appropriate, in this case, to conduct these second residual risk reviews under CAA section 112(f). In particular, the EPA is concerned about the cancer risks posed by the SOCMI source category due to the EPA's 2016 updated IRIS inhalation URE for EtO, which shows EtO to be significantly more toxic than previously known.

                         This updated URE was not available in 2006, when the EPA conducted its last RTR, but if this URE had been available, the EPA would almost undoubtedly have reached different conclusions about risk acceptability and the need to modify the standards to provide an ample margin of safety to protect public health. Similarly, for chloroprene, when the EPA conducted the first residual risk assessment for the SOCMI and Neoprene Production source categories, there was no inhalation URE for chloroprene. Therefore, in those risk reviews, the EPA attributed no cancer risk to chloroprene. The EPA concluded development of the IRIS inhalation URE for chloroprene in 2010. That URE allows us to assess, for the first time, the cancer risks posed by chloroprene. Had the EPA had the benefit of this new URE at the time it conducted the 2006 and 2008 RTRs, the URE would almost undoubtedly have impacted our conclusions about risk acceptability and the P&amp;R I standards' provision of an ample margin of safety to protect public health. Instead, we are conducting that analysis in this action.

                        In order to ensure our standards provide an ample margin of safety to protect public health following the new IRIS inhalation UREs for EtO and chloroprene, we are exercising our discretion and conducting risk assessments in this action for HON sources and for affected sources producing neoprene subject to the P&amp;R I NESHAP. Finally, we note that on September 15, 2021, the EPA partially granted a citizen administrative petition requesting that the EPA conduct a second residual risk review under CAA section 112(f)(2) for the HON, stating our intent to conduct a human health risk assessment concurrently with the section 112(d)(6) review.

                         Likewise, on March 4, 2022, the EPA partially granted another citizen administrative petition requesting that the EPA also conduct a second residual risk review under CAA section 112(f) for the Neoprene Production source category in the P&amp;R I NESHAP, stating that we intend to conduct a human health risk assessment concurrently with the section 112(d)(6) review.

                         This final rulemaking is partly undertaken in response to those citizen administrative petitions. In sum, even though we do not have a mandatory duty to conduct repeated residual risk reviews under CAA section 112(f)(2), we have the authority to revisit any rulemaking if there is: (1) Significant new scientific information suggesting the public is exposed to higher risks from facilities subject to the HON and the P&amp;R I and P&amp;R II NESHAP than previously realized, as compared to the previous risk assessments prepared for earlier rulemakings, or (2) sufficient evidence that changes within the affected industry are exposing the public to new risks.

                    <HD SOURCE="HD3">2. NSPS</HD>
                    <P>The EPA's authority for the final NSPS rules is CAA section 111, which governs the establishment of standards of performance for stationary sources. Section 111(b)(1)(A) of the CAA requires the EPA Administrator to list categories of stationary sources that in the Administrator's judgment cause or contribute significantly to air pollution that may reasonably be anticipated to endanger public health or welfare. The EPA must then issue performance standards for new (and modified or reconstructed) sources in each source category pursuant to CAA section 111(b)(1)(B). These standards are referred to as new source performance standards, or NSPS. The EPA has the authority to define the scope of the source categories, determine the pollutants for which standards should be developed, set the emission level of the standards, and distinguish among classes, types, and sizes within categories in establishing the standards.</P>
                    <P>CAA section 111(b)(1)(B) requires the EPA to “at least every 8 years review and, if appropriate, revise” NSPS. However, the Administrator need not review any such standard if the “Administrator determines that such review is not appropriate in light of readily available information on the efficacy” of the standard. When conducting a review of an existing performance standard, the EPA has the discretion and authority to add emission limits for pollutants or emission sources not currently regulated for that source category.</P>
                    <P>
                        In setting or revising a performance standard, CAA section 111(a)(1) provides that performance standards are to reflect “the degree of emission limitation achievable through the application of the BSER which (taking into account the cost of achieving such reduction and any nonair quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated.” The term “standard of performance” in CAA section 111(a)(1) makes clear that the EPA is to determine both the BSER for the regulated sources in the source category and the degree of emission limitation achievable through application of the BSER. The EPA must then, under CAA section 111(b)(1)(B), promulgate standards of performance for new sources that reflect that level of stringency. CAA section 111(h)(1) authorizes the Administrator to promulgate “a design, equipment, work practice, or operational standard, or combination thereof” if in his or her judgment, “it is not feasible to prescribe or enforce a standard of performance.” CAA section 111(h)(2) provides the circumstances under which prescribing or enforcing a standard of performance is “not feasible,” such as, when the pollutant cannot be emitted through a conveyance designed to emit or capture the pollutant, or when there is no practicable measurement methodology for the particular class of sources. CAA section 111(b)(5) precludes the EPA from prescribing a particular technological system that must be used 
                        <PRTPAGE P="42942"/>
                        to comply with a standard of performance. Rather, sources can select any measure or combination of measures that will achieve the standard.
                    </P>
                    <P>
                        Pursuant to the definition of new source in CAA section 111(a)(2), standards of performance apply to facilities that begin construction, reconstruction, or modification after the date of publication of the proposed standards in the 
                        <E T="04">Federal Register</E>
                        . Under CAA section 111(a)(4), “modification” means any physical change in, or change in the method of operation of, a stationary source which increases the amount of any air pollutant emitted by such source or which results in the emission of any air pollutant not previously emitted. Changes to an existing facility that do not result in an increase in emissions are not considered modifications. Under the provisions in 40 CFR 60.15, reconstruction means the replacement of components of an existing facility such that: (1) The fixed capital cost of the new components exceeds 50 percent of the fixed capital cost that would be required to construct a comparable entirely new facility; and (2) it is technologically and economically feasible to meet the applicable standards.
                    </P>
                    <P>In the development of NSPS for the SOCMI source category, the EPA considered emission sources associated with unit processes, storage and handling equipment, fugitive emission sources, and secondary sources. In 1983, the EPA promulgated NSPS for VOC from equipment leaks in SOCMI (40 CFR part 60, subpart VV). In 1990, the EPA promulgated NSPS (40 CFR part 60, subparts III and NNN) for VOC from air oxidation unit processes and distillation operations in the SOCMI (55 FR 26912 and 55 FR 26931). In 1993, the EPA promulgated NSPS (40 CFR part 60, subpart RRR) for VOC from reactor processes in the SOCMI (58 FR 45948). In 2007, based on its review of NSPS subpart VV, the EPA promulgated certain amendments to NSPS subpart VV and new NSPS (40 CFR part 60, subpart VVa) for VOC from certain equipment leaks in the SOCMI (72 FR 64883). This final action presents the required CAA 111(b)(1)(B) review of the NSPS for the air oxidation unit processes (subpart III), distillation operations (subpart NNN), reactor processes (subpart RRR), and equipment leaks (subpart VVa).</P>

                    <P>
                        In addition to the final action under CAA section 111(b)(1)(B) described above, this action includes final amendments to the NSPS subparts VV and VVa (NSPS for VOC from equipment leaks in SOCMI) based on its reconsideration of certain aspects of these NSPS subparts that were raised in an administrative petition which the Agency granted pursuant to section 307(d)(7)(B) of the CAA. In January 2008, the EPA received one petition for reconsideration of the NSPS for VOC from equipment leaks in SOCMI (40 CFR part 60, subparts VV and VVa) and the NSPS for equipment leaks in petroleum refineries (40 CFR part 60, subparts GGG and GGGa) pursuant to CAA section 307(d)(7)(B) from the following petitioners: American Chemistry Council, American Petroleum Institute (API), and National Petrochemical and Refiners Association (now the American Fuel and Petrochemical Manufacturers). A copy of the petition and subsequent EPA correspondence granting reconsideration is provided in the docket for this rulemaking (see Docket No. EPA-HQ-OAR-2022-0730). The petitioners primarily requested that the EPA reconsider four provisions in those rules: (1) The clarification of the definition of process unit in subparts VV, VVa, GGG, and GGGa; (2) the assignment of shared storage vessels to specific process units in subparts VV, VVa, GGG, and GGGa; (3) the monitoring of connectors in subpart VVa; and (4) the definition of capital expenditure in subpart VVa.

                         The rationale for this request is provided in the petition. The petitioners also requested that the EPA stay the effectiveness of these provisions of the rule pending resolution of their petition for reconsideration. On March 4, 2008, the EPA sent a letter to the petitioners informing them that the EPA was granting their request for reconsideration on issues (2) through (4) above. The letter also indicated that the EPA was not taking action on the first issue related to the definition of process unit. Finally, the letter indicated that the EPA was granting a 90-day stay of the provisions of the rules under reconsideration (see CAA section 307(d)(7)(B)), as well as the clarification of the definition of process unit, because of its reliance upon the new provision on the allocation of shared storage vessels. On June 2, 2008, the EPA published three actions in the 
                        <E T="04">Federal Register</E>
                         relative to extending the 90-day stay. Specifically, the EPA published a direct final rule (73 FR 31372) and a parallel proposal (73 FR 31416) in the 
                        <E T="04">Federal Register</E>
                         to extend the stay until we took final action on the issues of which the EPA granted reconsideration. Under the direct final rule, the stay would take effect 30 days after the close of the comment period on the proposed stay if no adverse comments were received. The third notice published that same day was an interim final rule extending the 90-day stay at the time for an additional 60 days so that the stay would not expire before the direct final rule could take effect (73 FR 31376). The EPA did not receive adverse comments on the proposed stay and, as a result, the stay became effective August 1, 2008.

                    <P>NESHAP subpart G contains the standards for process vents, transfer racks, storage vessels, and wastewater at SOCMI facilities; it also includes emissions averaging provisions. NESHAP subpart G provides an equation representing a site-specific allowable overall emission limit for the combination of all emission sources subject to the HON at a SOCMI facility. Existing sources must demonstrate compliance using one of two approaches: the point-by-point compliance approach or the emissions averaging approach. New sources are not allowed to use emissions averaging, but rather must demonstrate compliance using the point-by-point approach. Under the point-by-point approach, the owner or operator would apply control to each Group 1 emission source. A Group 1 emission source is a point which meets the control applicability criteria, and the owner or operator must reduce emissions to specified levels; whereas a Group 2 emission source is one that does not meet the criteria and no additional emission reduction is required. Under the emissions averaging approach, an owner or operator may elect to control different groups of emission sources to different levels than specified by the point-by-point approach, as long as the overall emissions do not exceed the overall allowable emission level. For example, an owner or operator can choose not to control a Group 1 emission source (or to control the emission source with a less effective control technique) if the owner or operator over-controls another emission source. For the point-by-point approach, NESHAP subpart G contains the following standards:</P>

Generally, the P&amp;R I NESHAP applies to EPPUs and associated equipment. Similar to a CMPU in the HON, an EPPU means a collection of equipment assembled and connected by hard-piping or duct work used to process raw materials and manufacture elastomer product. The EPPU includes unit operations, recovery operations, process vents, storage vessels, and equipment that are covered by equipment leak standards and produce one of the elastomer types listed as an elastomer product, including: butyl rubber, epichlorohydrin elastomer, ethylene propylene rubber, halobutyl rubber, Hypalon

Process vents are also regulated emission sources but, unlike the HON, these emissions sources are subdivided into front and back-end process vents in the P&amp;R I NESHAP. The front-end are unit operations prior to and including the stripping operations. These are further subdivided into continuous front-end process vents regulated under NESHAP subpart G and batch front-end process vents that are regulated according to the requirements within the P&amp;R I NESHAP. Back-end unit operations include filtering, coagulation, blending, concentration, drying, separating, and other finishing operations, as well as latex and crumb storage. The requirements for back-end process vents are not subcategorized into batch or continuous and are also found within the P&amp;R I NESHAP.</P>

                    <P>To reduce risk from the SOCMI source category to an acceptable level, we proposed under CAA section 112(f) to require (in the HON) control of EtO emissions from: (1) Process vents, (2) storage vessels, (3) equipment leaks, (4) heat exchange systems, and (5) wastewater “in ethylene oxide service” (see 88 FR 25080, April 25, 2023, for our proposed definition of “in ethylene oxide service”). We also proposed requirements to reduce EtO emissions from maintenance vents, flares, and PRDs.</P>
                    <P>• For process vents and storage vessels in EtO service, we proposed owners and operators reduce emissions of EtO by either: (1) Venting emissions through a closed-vent system to a control device that reduces EtO by greater than or equal to 99.9 percent by weight, to a concentration less than 1 ppmv for each process vent and storage vessel, or to less than 5 lb/yr for all combined process vents; or (2) venting emissions through a closed-vent system to a flare meeting the proposed operating and monitoring requirements for flares in NESHAP subpart F.</P>
                    <P>• For equipment leaks in EtO service, we proposed the following combined requirements: monitoring of connectors in gas/vapor and light liquid service at a leak definition of 100 ppm on a monthly basis with no reduction in monitoring frequency and no delay of repair; light liquid pump monitoring at a leak definition of 500 ppm monthly; and gas/vapor and light liquid valve monitoring at a leak definition of 100 ppm monthly with no reduction in monitoring frequency and no delay of repair.</P>
                    <P>• For heat exchange systems in EtO service, we proposed to require owners or operators to conduct more frequent leak monitoring (weekly instead of quarterly) and repair leaks within 15 days from the sampling date (in lieu of the current 45-day repair requirement after receiving results of monitoring indicating a leak), and delay of repair would not be allowed.</P>
                    <P>• For wastewater in EtO service, we proposed to revise the Group 1 wastewater stream threshold for sources to include wastewater streams in EtO service.</P>
                    <P>• For maintenance vents, we proposed a requirement that owners and operators cannot release more than 1.0 ton of EtO from all maintenance vents combined in any consecutive 12-month period.</P>
                    <P>• For flares, we proposed a requirement that owners and operators can send no more than 20 tons of EtO to all of their flares combined from all HON emission sources at a facility in any consecutive 12-month period.</P>
                    <P>• For PRDs in EtO service, we proposed that any atmospheric PRD release is a violation of the standard.</P>
                    <P>To reduce risk from the Neoprene Production source category to an acceptable level, we proposed under CAA section 112(f) to require (in the P&amp;R I NESHAP) control of chloroprene for: (1) Process vents, (2) storage vessels, and (3) wastewater “in chloroprene service” (see 88 FR 25080, April 25, 2023, for our proposed definition of “in chloroprene service”). We also proposed requirements to reduce chloroprene emissions from maintenance vents and PRDs.</P>
                    <P>
                        • For process vents and storage vessels in chloroprene service, we 
                        <PRTPAGE P="42946"/>
                        proposed owners and operators reduce emissions of chloroprene by venting emissions through a closed-vent system to a control device that reduces chloroprene by greater than or equal to 99.9 percent by weight, to a concentration less than 1 ppmv for each process vent and storage vessel, or to less than 5 lb/yr for all combined process vents.
                    </P>
                    <P>• For wastewater in chloroprene service, we proposed to revise the Group 1 wastewater stream threshold for sources to include wastewater streams in chloroprene service.</P>
                    <P>• For maintenance vents, we proposed a requirement that owners and operators cannot release more than 1.0 ton of chloroprene from all maintenance vents combined in any consecutive 12-month period.</P>
                    <P>• For PRDs in chloroprene service, we proposed that any atmospheric PRD release is a violation of the standard.</P>
                    <P>• We also proposed a facility-wide chloroprene emissions cap for all neoprene production emission sources as a backstop.</P>
                    <P>Based on our ample margin of safety analysis, we proposed that the controls to reduce EtO emissions at HON processes and chloroprene emissions at neoprene production processes to get risks to an acceptable level (described in this section of the preamble) would also provide an ample margin of safety to protect public health. We also proposed that HAP emissions from the source categories do not result in an adverse environmental effect, and that it is not necessary to set a more stringent standard to prevent, taking into consideration costs, energy, safety, and other relevant factors, an adverse environmental effect.</P>
                    <HD SOURCE="HD3">b. Proposed Actions Related to CAA Section 112(d)(6) Technology Review</HD>
                    <P>Pursuant to the CAA section 112(d)(6) technology review for the HON and the P&amp;R I, and P&amp;R II NESHAP, we proposed that no revisions to the current standards beyond the fenceline monitoring work practice standard discussed below and those proposed under CAA section 112(f) are necessary for transfer racks, wastewater streams, and equipment leaks; however, we did propose additional changes under CAA section 112(d)(6) for heat exchange systems, storage vessels and process vents.</P>
                    <P>• For HON and P&amp;R I heat exchange systems, we proposed requirements that owners or operators must use the Modified El Paso Method and repair leaks of total strippable hydrocarbon concentration (as methane) in the stripping gas of 6.2 ppmv or greater. The P&amp;R II NESHAP currently does not regulate HAP emissions from heat exchange systems.</P>
                    <P>
                        • For HON and P&amp;R I storage vessels, we proposed to revise applicability thresholds to require existing storage vessels between 38 m
                        <SU>3</SU>
                         (10,000 gal) and 151 m
                        <SU>3</SU>
                         (40,000 gal) with a vapor pressure ≥6.9 kilopascals to add control, and also require upgraded deck fittings and controls for guidepoles for all IFR storage vessels. For P&amp;R II storage vessels, we proposed that no revisions to the current standards are necessary.
                    </P>
                    <P>• For HON and P&amp;R I process vents, we proposed to: (1) Remove the TRE concept in its entirety; (2) remove 50 ppmv and 0.005 scmm Group 1 process vent thresholds; and (3) redefine a Group 1 process vent (require control) as any process vent that emits ≥1.0 lb/hr of total organic HAP. For P&amp;R II process vents, we proposed that no revisions to the current standards are necessary.</P>
                    <P>
                        Under CAA section 112(d)(6), we also proposed a fenceline monitoring work practice standard requiring owners and operators to monitor for any of six specific HAP (
                        <E T="03">i.e.,</E>
                         benzene, 1,3-butadiene, ethylene dichloride, vinyl chloride, EtO, and chloroprene) if their site uses, produces, stores, or emits any of them, and conduct root cause analysis and corrective action upon exceeding the annual average concentration action level set forth for each HAP. We also requested public comments on whether to promulgate the fenceline monitoring work practice standards, including the proposed action levels for EtO and chloroprene, under the second step of the CAA section 112(f)(2) residual risk decision framework to provide an ample margin of safety to protect public health in light of facility-wide risks.

                    <P>This action finalizes the EPA's determinations pursuant to the applicable provisions of CAA section 112 for the SOCMI source category and various polymers and resins source categories and amends the HON and P&amp;R I and P&amp;R II NESHAP based on those determinations. In addition, this action finalizes determinations of our review of the SOCMI NSPS rules pursuant to CAA section 111(b)(1)(B). This actions also finalizes other changes to the NESHAP, including adding requirements and clarifications for periods of SSM and bypasses; revising the operating and monitoring requirements for flares; adding provisions for electronic reporting; and other editorial and technical changes. Additionally, this action finalizes amendments to NSPS subparts VV and VVa in response to the January 2008 petition for reconsideration. This action also reflects several changes to the April 25, 2023 proposal (88 FR 25080), in consideration of comments received during the public comment period as described in section IV of this preamble.</P>
                    <HD SOURCE="HD2">A. What are the final rule amendments based on the risk review for the SOCMI and Neoprene Production source categories NESHAP?</HD>
                    <P>
                        Consistent with the proposal, the EPA determined that the risks for the SOCMI and Neoprene Production source categories under the previous MACT standards are unacceptable. When risks are unacceptable, the EPA must determine the emissions standards necessary to reduce risk to an acceptable level. As such, the EPA is promulgating final amendments to the HON pursuant to CAA section 112(f)(2) that require control of EtO for: (1) Process vents, (2) storage vessels, (3) equipment leaks, (4) heat exchange systems, and (5) wastewater “in ethylene oxide service.” We are also finalizing requirements to reduce EtO emissions from maintenance vents and PRDs. As discussed in section IV.A of this preamble, implementation of these controls will reduce risk to an acceptable level and provide an ample margin of safety to protect public health from source category emissions points. In addition, the fenceline monitoring requirements being finalized in this action will further reduce whole-facility EtO and chloroprene emissions at facilities with HON and Neoprene Production processes, with consequential reductions in risks from these pollutants. In general, we are finalizing all of the EtO related requirements as proposed (for HON), except: we are not finalizing (in response to persuasive comments received during the public comment period) the proposed requirement at 40 CFR 63.108(p) that would prohibit owners and operators from sending more than 20 tons of EtO to all of their flares combined in any consecutive 12-month period. In addition to the primary CAA section 112(d)(6)-based fenceline monitoring program action levels that we are finalizing for all six HAP that reflect compliance with the source category-specific emissions limits for SOCMI and P&amp;R I source category processes (see section III.B.1 of this preamble), we are also finalizing separately, in the P&amp;R I NESHAP for Neoprene Production sources, an additional secondary action level under CAA section 112(f)(2) for fenceline monitoring of chloroprene emissions. This secondary action level for chloroprene for facilities with Neoprene Production sources is the same action level that was proposed. The primary chloroprene action level, which applies to sources subject to 40 CFR subpart H in the HON, is higher than what was proposed, but reflects the modeled emissions concentrations expected to result from compliance with the other emission standards adopted in the final rule, as we discussed in the proposed rule. 
                        <E T="03">See</E>
                         88 FR at 25145/col. 2. The secondary chloroprene action level will further reduce whole-facility risks caused by such emissions from facilities with Neoprene Production sources, consistent with the goal to provide an ample margin of safety to protect public health. For this reason, for facilities with Neoprene Production sources we are promulgating the secondary chloroprene action level we had proposed under CAA section 112(d)(6)

                    <P>Also, based on comments received on the proposed rulemaking, we are clarifying in this final action that:</P>
                    <P>• we mean “the procedures specified in § 63.109” instead of “sampling and analysis” within the definitions of “in ethylene oxide service” for storage vessels, equipment leaks, and heat exchange systems (see 40 CFR 63.101);</P>
                    <P>• the sampling site for determining whether an emissions source is in EtO service is after the last recovery device (if any recovery devices are present) but prior to the inlet of any control device that is present and prior to release to the atmosphere (see 40 CFR 63.109(a));</P>
                    <P>• owners and operators can use good engineering judgment to determine the percent of EtO of the process fluid cooled by the heat exchange system similar to what we are allowing for equipment leaks in 40 CFR 63.109(c)(2) (see 40 CFR 63.109(e));</P>
                    <P>• the 5 lb/yr EtO mass threshold for combined process vents in EtO service is on a CMPU-by-CMPU basis (see 40 CFR 63.113(j)(2), 40 CFR 63.124(a)(4) and (a)(4)(iii), and within the definition of “in ethylene oxide service” for process vents);</P>
                    <P>• owners and operators may delay repair of equipment leaks in EtO service, and heat exchange systems in EtO service, indefinitely as long as there is no longer an active EtO leak once the equipment is isolated and not in EtO service (see 40 CFR 63.104(h)(6) and 40 CFR 63.171(b));</P>
                    <P>• we mean “process wastewater” instead of “wastewater” in 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii);</P>
                    <P>• owners and operators can demonstrate compliance with the standards for wastewater in EtO service if the concentration of EtO is reduced, by removal or destruction, to a level less than 1 ppmw as determined in the procedures specified in 40 CFR 63.145(b) (see 40 CFR 63.138(b)(3) and (c)(3)); and</P>
                    <P>• owners and operators can use test methods specified in 40 CFR 63.109(d) for analysis of EtO in wastewater (see 40 CFR 63.144(b)(5)(i)).</P>
                    <P>Additionally, the EPA is promulgating final amendments to the P&amp;R I NESHAP for Neoprene Production sources pursuant to CAA section 112(f)(2) that require control of chloroprene for: (1) Process vents, (2) storage vessels, (3) wastewater “in chloroprene service.” We are also finalizing requirements to reduce chloroprene emissions from maintenance vents and PRDs. As discussed in section IV.A of this preamble, implementation of these controls will reduce risk to an acceptable level and provide an ample margin of safety to protect public health from the Neoprene Production source category. In general, we are finalizing all of the chloroprene related requirements as proposed (for Neoprene Production sources in the P&amp;R I NESHAP), except in response to persuasive comments received during the public comment period: (1) We are not finalizing the facility-wide chloroprene emissions cap at 40 CFR 63.483(a)(10) that would prohibit owners and operators from emitting 3.8 tpy of chloroprene in any consecutive 12-month period from all neoprene production emission sources; (2) we are revising the performance standard from a 99.9 percent by weight reduction requirement to a 98 percent by weight reduction requirement for storage vessels in chloroprene service (see 40 CFR 63.484(u) and 40 CFR 53.510), continuous front-end process vents in chloroprene service (see 40 CFR 63.485(y) and 40 CFR 53.510), and batch front-end process vents in chloroprene service (see 40 CFR 63.487(j)); (3) we are finalizing a requirement that owners and operators reduce emissions of chloroprene from back-end process vents in chloroprene service at affected sources producing neoprene by venting emissions through a closed-vent system to a non-flare control device that reduces chloroprene by greater than or equal to 98 percent by weight, to a concentration less than 1 ppmv for each process vent, or to less than 5 lb/yr for all combined process vents (see 40 CFR 63.494(a)(7)); and (4) we are finalizing in the primary CAA section 112(d)(6)-based fenceline monitoring program action levels for all six HAP addressed in the proposal that reflect compliance with the source category-specific emissions limits for SOCMI and P&amp;R I source category processes, and which subject sources are largely already meeting (see section III.B.1 of this preamble). Separately, we are also setting an additional secondary action level under CAA section 112(f)(2) for fenceline monitoring of chloroprene emissions. This standard will further reduce whole-facility risks caused by such emissions, consistent with the goal to provide an ample margin of safety to protect public health. Also, based on comments received on the proposed rulemaking, we are clarifying in this final action that:</P>
                    <P>• we mean “the procedures specified in § 63.509” instead of “sampling and analysis” within the definitions of “in chloroprene service” for storage vessels (see 40 CFR 63.482);</P>
                    <P>• the sampling site for determining whether an emissions source is in chloroprene service is after the last recovery device (if any recovery devices are present) but prior to the inlet of any control device that is present and prior to release to the atmosphere (see 40 CFR 63.509(a)); and</P>
                    <P>• the 5 lb/yr chloroprene mass threshold for combined process vents in chloroprene service is on a EPPU-by-EPPU basis (see the definition of “in chloroprene service” for process vents).</P>
                    <P>Section IV.A.3 of this preamble provides a summary of key comments we received on the CAA section 112(f) provisions and our responses.</P>

                    <P>For transfer racks, wastewater streams, and equipment leaks in the SOCMI, P&amp;R I, and P&amp;R II source categories, the EPA is finalizing its proposed determination in the technology review that there are no developments in practices, processes, and control technologies that warrant revisions to the MACT standards beyond those needed under CAA section 112(f) or for other purposes besides section 112(d)(6). Therefore, with the exception of the fenceline monitoring standards that are discussed further below, we are not finalizing revisions to the MACT standards for these emission sources under CAA section 112(d)(6).</P>
                    <P>
                        For heat exchange systems, we determined that there are developments in practices, processes, and control technologies that warrant revisions to the MACT standards for heat exchange systems in the SOCMI, P&amp;R I, and P&amp;R II source categories. Therefore, to satisfy the requirements of CAA section 112(d)(6), we are revising the MACT standards, consistent with the proposed rule (88 FR 25080, April 25, 2023), to include revisions to the heat exchange system requirements to require owners or operators to use the Modified El Paso Method and repair leaks of total strippable hydrocarbon concentration (as methane) in the stripping gas of 6.2 ppmv or greater. We are also finalizing, as proposed, that owners and operators may use the current leak monitoring requirements for heat exchange systems at 40 CFR 63.104(b) in lieu of using the Modified El Paso Method provided that 99 percent by weight or more of the

See 40 CFR 63.104(g) through (j) and (l) (for HON), 40 CFR 63.502(n)(7) (for the P&amp;R I NESHAP), and 40 CFR 63.523(d) and 40 CFR 63.524(c) (for the P&amp;R II NESHAP).

                        For storage vessels, we did not identify any control options for storage tanks subject to the P&amp;R II NESHAP. However, we determined that there are developments in practices, processes, and control technologies that warrant revisions to the MACT standards for storage vessels in the SOCMI and P&amp;R I source categories. Therefore, to satisfy the requirements of CAA section 112(d)(6), we are revising the MACT standards, consistent with the proposed rule (88 FR 25080, April 25, 2023), to include revisions to the storage vessel applicability threshold to require both existing and new storage vessels between 38 m
                        <SU>3</SU>
                         and 151 m

                         with a vapor pressure greater than or equal to 6.9 kilopascals to reduce emissions of organic HAP by 95 percent utilizing a closed vent system and control device, or reduce organic HAP emissions either by utilizing an IFR, an EFR, or by routing the emissions to a process or a fuel gas system, or vapor balancing. We are also finalizing, as proposed, requirements that all openings in an IFR (except those for automatic bleeder vents (vacuum breaker vents), rim space vents, leg sleeves, and deck drains) be equipped with a deck cover; and that the deck cover be equipped with a gasket between the cover and the deck; and control requirements for guidepoles for all storage vessels equipped with an IFR. See Tables 5 and 6 to subpart G, and 40 CFR 63.119(b)(5)(ix), (x), (xi), and (xii) (for HON) and 40 CFR 63.484(t) (for the P&amp;R I NESHAP).

                        For process vents, we did not identify any control options for process vents subject to the P&amp;R II NESHAP. However, we determined that there are developments in practices, processes, and control technologies that warrant revisions to the MACT standards for process vents in the SOCMI and P&amp;R I source categories. Therefore, to satisfy the requirements of CAA section 112(d)(6), we are revising the MACT standards, consistent with the proposed rule (88 FR 25080, April 25, 2023), to include revisions to the process vent applicability threshold to redefine a HON Group 1 process vent and P&amp;R I Group 1 continuous front-end process vent (
                        <E T="03">i.e.,</E>
                         to require control) as any process vent that emits greater than or equal to 1.0 lb/hr of total organic HAP. We are also removing, as proposed, the TRE concept in its entirety, and removing, as proposed, the 50 ppmv and 0.005 scmm Group 1 process vent thresholds. See 40 CFR 63.101 and 40 CFR 63.113(a)(1), (2), and (4) (for HON) and 40 CFR 63.482 and 40 CFR 63.485(l)(6), (o)(6), (p)(5), and (x) (for the P&amp;R I NESHAP). To satisfy the requirements of CAA section 112(d)(6), we are also revising the MACT standards, consistent with the proposed rule (88 FR 25080, April 25, 2023), to include revisions to the process vent applicability threshold to redefine a P&amp;R I Group 1 batch front-end process vent as process vents that release total annual organic HAP emissions greater than or equal to 4,536 kg/yr (10,000 lb/yr) from all batch front-end process vents combined. See 40 CFR 63.482, 40 CFR 63.487(e)(1)(iv), 40 CFR 63.488(d)(2), (e)(4), (f)(2), and (g)(3) (for the P&amp;R I NESHAP).

                    <P>
                        Also, to satisfy the requirements of CAA section 112(d)(6), we are revising the MACT standards, consistent with the proposed rule (88 FR 25080, April 25, 2023), to include a fenceline monitoring work practice standard for the SOCMI and P&amp;R I source categories, requiring owners and operators to monitor for any of six specific HAP (
                        <E T="03">i.e.,</E>
                         benzene, 1,3-butadiene, ethylene dichloride, vinyl chloride, EtO, and chloroprene) if their affected source uses, produces, stores, or emits any of them, and to conduct root cause analysis and corrective action upon exceeding the annual average concentration action level set forth for each HAP. However, based on comments received on the proposed rulemaking, we are amending the fenceline monitoring work practice standards in the final rule adopted under CAA section 112(d)(6) to include the action level of 0.8 ug/m
                        <SU>3</SU>
                         for chloroprene, which reflects compliance with the source category-specific emissions limits for P&amp;R I source category processes. The action levels for benzene, 1,3-butadiene, ethylene dichloride, EtO, and vinyl chloride will also correspond to the modeled concentrations resulting from compliance with the process emission standards promulgated in the final rule and/or levels that HON-subject sources are largely already meeting. Separately, we are also setting an additional secondary action level of 0.3 ug/m
                        <SU>3</SU>
                         for chloroprene under CAA section 112(f)(2), because this standard will further reduce elevated risks from facility-wide emissions of this pollutant consistent with the goal to provide an ample margin of safety to protect public health. See 40 CFR 63.184 (for HON) and 40 CFR 63.502 (for the P&amp;R I NESHAP). In addition, the final rule includes burden reduction measures to allow owners and operators to skip fenceline measurement periods for specific monitors with a history of measurements that are at or below certain specified action levels. We have also made a clarification that fenceline monitoring is required for owners and operators with affected sources that produce, store, or emit one or more of the target analytes; and we have reduced the requirements in the final rule for the minimum detection limit of alternative measurement approaches (for fenceline monitoring). In addition, we have made clarifications on the calculation of delta c (Δc) 
                        <SU>27</SU>
                        <FTREF/>
                         when a site-specific monitoring plan is used to correct monitoring location concentrations due to offsite impacts, and we have made a change in the required method detection limit for alternative test methods from an order of magnitude below the action level to one-third of the action level. Finally, with the exception of fenceline monitoring of chloroprene at P&amp;R I affected sources producing neoprene, discussed below, we have changed the compliance date to begin fenceline monitoring from 1 to 2 years after the effective date of the final rule. For P&amp;R I affected sources producing neoprene, we have changed the compliance date for fenceline monitoring of chloroprene to begin no later than October 15, 2024, or upon startup, whichever is later, subject to the owner or operator seeking the EPA's authorization of an extension of up to 2 years from July 15, 2024.

                        The EPA is finalizing, as proposed, a determination that the BSER for reducing VOC emissions from SOCMI air oxidation units, distillation operations, and reactor processes remains combustion (
                        <E T="03">e.g.,</E>
                         incineration, flares), and we are also maintaining that the standard of performance of 98 
                        <PRTPAGE P="42950"/>
                        percent reduction of TOC (minus methane and ethane), or reduction of TOC (minus methane and ethane) to an outlet concentration of 20 ppmv on a dry basis corrected to 3 percent oxygen, continues to reflect the BSER for NSPS subparts IIIa, NNNa, and RRRa. While we are finalizing no changes in the BSER for reducing VOC emissions from SOCMI air oxidation units, distillation operations, and reactor processes, we determined that there are certain advances in process operations that were not identified or considered during development of the original NSPS subparts III, NNN, and RRR (for SOCMI air oxidation units, distillation operations, and reactor processes, respectively), which warrant revisions to the requirements for process vents in the SOCMI source category. Therefore, pursuant to CAA section 111(b)(1)(B), we are finalizing revised process vent requirements in new NSPS subparts IIIa, NNNa, and RRRa (for SOCMI air oxidation unit processes, distillation operations, and reactor processes for which construction, reconstruction, or modification commenced after April 25, 2023), consistent with the proposed rule (88 FR 25080, April 25, 2023). In particular, we are finalizing for NSPS subparts IIIa, NNNa and RRRa, as proposed, the removal of the entire TRE concept (including the removal of the alternative of maintaining a TRE index value greater than 1 without the use of control device and the limited applicability exemptions) such that owners and operators of affected facilities (for which construction, reconstruction, or modification commences after April 25, 2023) are required to reduce emissions of TOC (minus methane and ethane) from all vent streams of an affected facility by 98 percent by weight or to a concentration of 20 ppmv on a dry basis corrected to 3 percent oxygen, or combust the emissions in a flare. The EPA is also finalizing, as proposed, that affected sources that combust the emissions in a flare meet the same operating and monitoring requirements for flares that we are finalizing for flares subject to the HON. However, based on comments received on the proposed rulemaking, we are finalizing a mass-based exemption criteria of 0.001 lb/hr TOC (for which emission controls are not required) in new NSPS subparts IIIa and NNNa. Also, as proposed, we are not including in the final NSPS subparts IIIa, NNNa, and RRRa a relief valve discharge exemption in the definition of “vent stream”; instead, any relief valve discharge to the atmosphere of a vent stream is a violation of the emissions standard. In addition, we are finalizing, as proposed, the same work practice standards for maintenance vents that we are finalizing for HON process vents, and, as proposed, the same monitoring requirements that we are finalizing for HON process vents for adsorbers that cannot be regenerated and regenerative adsorbers that are regenerated offsite.
                    </P>
                    <P>For equipment leaks, we determined that there are techniques used in practice related to LDAR of certain equipment that achieve greater emission reductions than those currently required by NSPS subpart VVa. Therefore, pursuant to the requirements of CAA section 111(b)(1)(B), we are finalizing revised equipment leak requirements in new NSPS subpart VVb (for facilities that commence construction, reconstruction, or modification after April 25, 2023), consistent with the proposed rule (88 FR 25080, April 25, 2023). We are finalizing that BSER for gas and light liquid valves is the same monitoring in an LDAR program as NSPS subpart VVa, but now at a leak definition of 100 ppm, and BSER for connectors is monitoring in the LDAR program at a leak definition of 500 ppm and monitored annually, with reduced frequency for good performance. In a change from the proposed rule, we are finalizing a definition of “capital expenditure” in NSPS subpart VVb to use a formula that better reflects the trajectory of inflation.</P>

However, based on comments received on the proposed rulemaking, we are clarifying in the final rule that 40 CFR 63.119(b)(7) applies only if a continuous sweep, purge, or inert blanket is used between the IFR and fixed roof that causes a pressure/vacuum vent to remain continuously open to the atmosphere where uncontrolled emissions are greater than or equal to 1.0 lb/hr of total organic HAP.</P>

                    <HD SOURCE="HD3">1. NESHAP</HD>
                    <P>
                        We are finalizing the proposed amendments to the HON and the P&amp;R I and P&amp;R II NESHAP to remove and revise provisions related to SSM. In its 2008 decision in 
                        <E T="03">Sierra Club</E>
                         v. 
                        <E T="03">EPA,</E>
                         551 F.3d 1019 (D.C. Cir. 2008), the Court vacated portions of two provisions in the EPA's CAA section 112 regulations governing the emissions of HAP during periods of SSM. Specifically, the Court vacated the SSM exemptions contained in 40 CFR 63.6(f)(1) and (h)(1), holding that under section 302(k) of the CAA, emissions standards or limitations must be continuous in nature, and that the SSM exemptions violated the CAA's requirement that some CAA section 112 standards apply at all times. We are finalizing, as proposed, a requirement that the standards apply at all times (see 40 CFR 63.102(e) (for HON) and 40 CFR.525(j) (for the P&amp;R II NESHAP)), consistent with the 
                        <E T="03">Sierra Club</E>
                         decision. We determined that facilities in the SOCMI and P&amp;R II source categories can meet the applicable MACT standards at all times, including periods of startup and shutdown. We note that on April 21, 2011 (see 77 FR 22566), the EPA finalized amendments to eliminate the SSM exemption in the P&amp;R I NESHAP; however, for consistency with the SSM-related amendments that we are finalizing for the HON and the P&amp;R II NESHAP, we are also finalizing, as proposed, additional amendments to the P&amp;R I NESHAP related to the SSM exemption that were not addressed in the April 21, 2011, P&amp;R I rule.
                    </P>
                    <P>As discussed in the proposal preamble, the EPA interprets CAA section 112 as not requiring emissions that occur during periods of malfunction to be factored into development of CAA section 112 standards, although the EPA has the discretion to set standards for malfunction periods where feasible. Where appropriate, and as discussed in section III.C of this preamble, we are also finalizing alternative standards for certain emission points during periods of SSM to ensure a CAA section 112 standard applies “at all times.” Other than for those specific emission points discussed in section III.C of this preamble, the EPA determined that no additional standards are needed to address emissions during periods of SSM and that facilities in the SOCMI and P&amp;R II source categories can meet the applicable MACT standards at all times, including periods of startup and shutdown.</P>
                    <P>
                        We are also finalizing, as proposed, revisions to the HON and P&amp;R II General Provisions tables (Table 3 to subpart F of part 63 and Table 1 to subpart W of part 63, respectively) to eliminate requirements that include rule language providing an exemption for periods of SSM. We note that the EPA already made a similar revision to the General Provisions table to the P&amp;R I NESHAP (see 77 FR 22566, April 21, 2011). Additionally, we are finalizing our proposal to eliminate language related to SSM that treats periods of startup and shutdown the same as periods of malfunction. Finally, we are finalizing our proposal to revise reporting and recordkeeping requirements for deviations as they relate to exemptions for periods of SSM. These revisions are consistent with the requirement in 40 CFR 63.102(e) and 40 CFR.525(j) that the standards apply at all times. We are also finalizing, as proposed, a revision to the performance testing requirements. The final performance testing provisions prohibit performance testing during SSM because these conditions are not representative of normal operating conditions. The final rule also requires, as proposed, that operators maintain records to document that operating conditions during the test represent normal operations. In light of

                        section 111 because the definition of “emission” or “standard” in CAA section 302(k), and the embedded requirement for continuous standards, also applies to the NSPS.

The NSPS general provisions in 40 CFR 60.8(c) currently exempt non-opacity emission standards during periods of SSM. We are finalizing, as proposed, specific requirements in NSPS subparts IIIa, NNNa, and RRRa that override the general provisions for SSM (see 40 CFR 60.612a, 40 CFR 60.662a, and 40 CFR 60.702a, respectively).

                    <P>In response to the January 2008 petition for reconsideration, we are finalizing, as proposed: (1) Definitions for “process unit” for NSPS subparts VV and VVa; (2) removal of the requirements in 40 CFR 60.482-1(g) (for NSPS subpart VV) and 40 CFR 60.482-1a(g) (for NSPS subpart VVa) that are related to a method for assigning shared storage vessels to specific process units; and (3) removal of the connector monitoring provisions from NSPS subpart VVa at 40 CFR 60.482-11a in their entirety. However, based on comments received on the proposed rulemaking, we are revising the value of “X” in the capital expenditure equation of NSPS subpart VVa to correct an erroneous phrasing that attached the value of “X” in the percent Y equation to the date of construction, reconstruction and modification (as opposed to date of physical or operational change). In the final rule, we have revised the “capital expenditure” definition in NSPS subpart VVa at 40 CFR 60.481a such that for owners or operators that made a physical or operational change to their existing facility prior to November 16, 2007, the percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where the value of “X” is 1982 minus the year of construction, and for owners or operators that made a physical or operational change to their existing facility on or after November 16, 2007, the percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where the value of “X” is 2006 minus the year of construction. Section IV.E.3 of this preamble provides a summary of key comments we received on the NSPS subparts VV and VVa reconsideration issues and our responses.</P>

                        To increase the ease and efficiency of data submittal and data accessibility, we are finalizing, as proposed, a requirement that owners or operators submit electronic copies of certain required performance test reports, flare management plans, and periodic reports (including fenceline monitoring reports for HON and the P&amp;R I NESHAP) through the EPA's Central Data Exchange (CDX) using the Compliance and Emissions Data Reporting Interface (CEDRI) (see 40 CFR 63.108(e), 40 CFR 63.152(c) and (h), and 40 CFR 63.182(d) and (e) (for HON), 40 CFR 63.506(e)(6), and (i)(3) (for the P&amp;R I NESHAP), and 40 CFR 63.528(a) and (d) (for the P&amp;R II NESHAP), 40 CFR 60.486(l), and 60.487(a) and (g) through (i) (for NSPS subpart VV), 40 CFR 60.486a(l), and 60.487a(a) and (g) through (i) (for NSPS subpart VVa), 40 CFR 60.486b(l), and 60.487b(a) and (g) through (i) (for NSPS subpart VVb), 40 CFR 60.615(b), (j), (k), and (m) through (o) (for NSPS subpart III), 40 CFR 60.615a(b), (h) through (l), and (n), and 40 CFR 619a(e) (for NSPS subpart IIIa), 40 CFR 60.665(b), (l), (m), and (q) through (s) (for NSPS subpart NNN), 40 CFR 60.665a(b), (h), (k) through (n), and (p), and 40 CFR 669a(e) (for NSPS subpart NNNa), 40 CFR 60.705(b), (l), (m), and (u) through (w) (for NSPS subpart RRR), and 40 CFR 60.705a(b), (k) through (o), and (v), and 40 CFR 709a(e) (for NSPS subpart RRRa)).

For periodic reports (including fenceline monitoring reports), the final rule requires that owners or operators use the appropriate spreadsheet template to submit information to CEDRI. We have made minor clarifying edits to the spreadsheet templates based on comments received during the public comment period. The final version of the templates for these reports are located on the CEDRI website.

For example, for process vents, if an affected source has uncontrolled process vents that emit greater than or equal to 1.0 lb/hr of total organic HAP, then a new control system, such as a thermal oxidizer with piping, ductwork, etc., may need to be installed (due to the removal of the TRE concept in its entirety in the final rule). Also, additional permits (

                         New Source Review and/or a Title V permit modifications) may be required for new emission control equipment. Moreover, 3 years is needed to understand the final rule changes; revise site guidance and compliance programs; ensure operations can meet the standards during startup and shutdown; update operation, maintenance, and monitoring plans; upgrade emission capture and control systems; install new flare monitoring equipment; and install new process control systems. As provided in CAA section 112(i) and 5 U.S.C. 801(3), all new affected sources that commenced construction or reconstruction after April 25, 2023, are required to comply with all requirements under CAA sections 112(d)(2), (3), (6), and 112(h) (including fenceline monitoring) by July 15, 2024 or upon startup, whichever is later. We are also finalizing, as proposed, that owners or operators of P&amp;R I affected sources must comply with the removal of the affirmative defense provisions 60 days after the publication date of the final rule (or upon startup, whichever is later). We provided additional rationale for these compliance dates in the preamble to the proposed rule (88 FR 25080, April 25, 2023).

                        In a change from the proposed rule, we have extended the compliance date for fenceline monitoring (with the exception of fenceline monitoring of chloroprene at P&amp;R I affected sources producing neoprene, which is discussed later in this section) from 1 to 2 years. Owners and operators of all existing sources, and all affected sources that were new under the current rules—
                        <E T="03">i.e.,</E>
                         sources that commenced construction or reconstruction after December 31, 1992 (for HON) or after June 12, 1995 (for the P&amp;R I NESHAP), and on or before April 25, 2023—must begin fenceline monitoring 2 years after the effective date of the final rule and, starting 3 years after the effective date of the final rule, must perform root cause analysis and apply corrective action requirements upon exceedance of an annual average concentration action level. We extended the timeline for fenceline monitoring from 1 to 2 years based on comments received, which indicated that EPA Method 327 will require laboratories to increase their capacity to meet the requirements for fenceline monitoring. We consider this expanded timeline to be necessary to allow commercial labs to conduct the needed method development, expand capacity, and develop the logistics needed to meet the requirements in the final rule. We also agree with commenters' other assertions that more time is needed to read and assess the new fenceline monitoring requirements; prepare sampling and analysis plans; develop and submit site-specific monitoring plans; identify representative, accessible, and secure monitoring locations for offsite monitors and obtain permission from the property owner to both place and routinely access the monitors; make any necessary physical improvements to fencelines to be able to site monitors, including construction of access roads, physical fencing, and potential drainage improvements; and obtain approval of any necessary capital expenditures. We consider 2 years to be necessary to allow for all of these things. For additional details, see section 11.1 of the document titled

                        For all of the requirements we are finalizing under CAA sections 112(f) for the HON, we are finalizing as proposed, except we are clarifying that the compliance dates we proposed are from the effective date of the rule rather than the publication date of the proposal. In other words, all existing affected sources and all affected sources that were new sources under the previous HON (
                        <E T="03">i.e.,</E>
                         sources that commenced construction or reconstruction after December 31, 1992, and on or before April 25, 2023) must comply with the EtO requirements no later than July 15, 2026, or upon startup, whichever is later. As explained in the April 25, 2023, proposed rule (88 FR 25080, 25176), CAA section 112(f)(4) prescribes the compliance date for emission standards issued under CAA section 112(f).

                         (“[S]ection 112(f)(4)'s two-year maximum applies more specifically to standards `under this subsection,'

                         section 112(f).”). For existing sources, the earliest compliance date for CAA section 112(f) standards is 90 days. However, the compliance period can be extended up to 2 years if the EPA finds that more time is needed for the installation of controls. 42 U.S.C. 7412(f)(4)(B). The EPA finds that the new EtO provisions under CAA section 112(f) will require additional time to plan, purchase, and install emission control equipment. For example, for process vents, if an affected source cannot demonstrate 99.9-percent control of EtO emissions, or reduce EtO emissions to less than 1 ppmv (from each process vent) or 5 pounds per year (for all combined process vents), then a new control system, such as a scrubber with piping, ductwork, feed tanks, etc., may need to be installed. Similarly, this same scenario (
                        <E T="03">i.e.,</E>
                         installation of a new control system, such as a scrubber with piping, ductwork, feed tanks, etc) may be necessary for storage vessels in order to reduce EtO emissions by greater than or equal to 99.9 percent by weight or to a concentration less than 1 ppmv. Likewise, a new steam stripper may be needed control wastewater with a total annual average concentration of EtO greater than or equal to 1 ppmw. Additionally, we agree with commenters (see section 11.1 of the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         which is available in the docket for this rulemaking) that additional permits may be required for these new emission control equipment (

                         New Source Review and/or a Title V permit modifications). In other words, sufficient time is needed to properly engineer the project, obtain capital authorization and funding, procure the equipment, obtain permits, and construct and start-up the equipment. Therefore, we are finalizing a compliance date of 2 years after the effective date of the final rule for all existing affected sources to meet the EtO requirements. All new affected sources that commence construction or reconstruction after April 25, 2023, are required to comply with the EtO requirements for the HON by July 15, 2024 or upon startup, whichever is later.

                        This compliance schedule is consistent with the compliance deadlines outlined in the CAA under section 112(f)(4) and the CRA. We provided additional rationale for these compliance dates in the preamble to the proposed rule (88 FR 25080, April 25, 2023).

                    <P>The results of the proposed chronic baseline inhalation cancer risk assessment at proposal indicated that, based on estimates of current actual and allowable emissions, the maximum individual lifetime cancer risk posed by the source category was 2,000-in-1 million driven by EtO emissions from PRDs (74 percent) and equipment leaks (20 percent). At proposal, the total estimated cancer incidence from this source category was estimated to be 2 excess cancer cases per year. Approximately 7.2 million people were estimated to have cancer risks above 1-in-1 million from HAP emitted from the facilities in this source category. At proposal, the estimated maximum chronic noncancer target organ-specific hazard index (TOSHI) for the source category was 2 for respiratory effects at two different facilities (from maleic anhydride emissions at one facility and chlorine emissions at another facility).</P>
                    <P>
                        As shown in Table 1 of this preamble, the worst-case acute hazard quotient (HQ) (based on the reference exposure level (REL)) at proposal was 3 based on the RELs for chlorine and acrolein. In addition, at proposal, the multipathway risk screening assessment resulted in a maximum Tier 3 cancer screening value (SV) of 60 for mercury and 2 for cadmium for the fisher scenario, and 20 for polycyclic organic matter (POM) for the gardener scenario. At proposal, no site-specific assessment using TRIM.FaTE (which incorporates AERMOD deposition, enhanced soil/water run-off calculations, and model boundary identification) was deemed necessary. The EPA determined that it is not necessary to go beyond the Tier 3 lake analysis or conduct a site-specific assessment for cadmium, mercury, or POM. The EPA compared the Tier 3 screening results to site-specific risk estimates for five previously assessed source categories and concluded that if the Agency was to perform a site-specific assessment for the SOCMI source category, the HQ for ingestion exposure, specifically cadmium and mercury through fish ingestion, is at or below 1; and for POM, the maximum cancer risk under the rural gardener scenario would likely decrease to below 1-in-1 million. Also, at proposal, the highest annual average lead concentration of 0.004 micrograms per cubic meter (μg/m
                        <SU>3</SU>
                        ) was well below the National Ambient Air Quality Standards (NAAQS) for lead, indicating low potential for multipathway risk of concern due to lead emissions.

Regarding the noncancer risk assessment, the maximum chronic noncancer hazard index (HI) posed by whole-facility emissions was estimated to be 4 (for respiratory effects) due mostly (98 percent) to emissions from 2 facilities.</P>

                        We weighed all health risk measures and factors, including those shown in Table 1 of this preamble, in our risk acceptability determination and proposed that the risks posed by the SOCMI source category under the current MACT provisions are unacceptable (section III.B of the proposal preamble, 88 FR 25080, April 25, 2023). At proposal, we identified EtO as the driver of the unacceptable risk and evaluated several options to control EtO emissions from (1) process vents, (2) storage vessels, (3) equipment leaks, (4) heat exchange systems, and (5) wastewater “in ethylene oxide service.” 
                        <PRTPAGE P="42957"/>
                        We also proposed requirements to reduce EtO emissions from maintenance vents, flares, and PRDs.
                    </P>
                    <P>For process vents, we proposed to define “in ethylene oxide service” in the HON at 40 CFR 63.101 to mean each process vent in a process that, when uncontrolled, contains a concentration of greater than or equal to 1 ppmv undiluted EtO, and when combined, the sum of all these process vents would emit uncontrolled EtO emissions greater than or equal to 5 pounds per year (2.27 kilograms per year).</P>
                    <P>For storage vessels of any capacity and vapor pressure, we proposed to define “in ethylene oxide service” in the HON at 40 CFR 63.101 to mean that the concentration of EtO of the stored liquid is at least 0.1 percent by weight. Additionally, we proposed that unless specified by the Administrator, owners and operators may calculate the concentration of EtO of the fluid stored in a storage vessel if information specific to the fluid stored is available such as concentration data from safety data sheets. We also proposed that the exemption for “vessels storing organic liquids that contain organic hazardous air pollutants only as impurities” listed in the definition of “storage vessel” at 40 CFR 63.101 does not apply for storage vessels in EtO service.</P>
                    <P>For the EtO equipment leak provisions, we proposed to define “in ethylene oxide service” in the HON at 40 CFR 63.101 to mean any equipment that contains or contacts a fluid (liquid or gas) that is at least 0.1 percent by weight of EtO.</P>
                    <P>For heat exchange systems, we proposed to define “in ethylene oxide service” in the HON at 40 CFR 63.101 to mean each heat exchange system in a process that cools process fluids (liquid or gas) that are 0.1 percent or greater by weight of EtO.</P>
                    <P>For wastewater, we proposed to define “in ethylene oxide service” in the HON at 40 CFR 63.101 to mean each wastewater stream that contains total annual average concentration of EtO greater than or equal to 1 ppmw at any flow rate.</P>
                    <P>To reduce risks from process vents in EtO service, we proposed requirements at 40 CFR 63.113(j) to reduce emissions of EtO by either (1) venting emissions through a closed-vent system to a control device that reduces EtO by greater than or equal to 99.9 percent by weight, to a concentration less than 1 ppmv for each process vent, or to less than 5 lb/yr for all combined process vents; or (2) venting emissions through a closed-vent system to a flare meeting the flare operating requirements discussed in section III.B.4.a.i of the proposal preamble (88 FR 25080, April 25, 2023).</P>
                    <P>To reduce risks from storage vessels in EtO service, we proposed a requirement at 40 CFR 63.119(a)(5) to reduce emissions of EtO by either (1) venting emissions through a closed-vent system to a control device that reduces EtO by greater than or equal to 99.9 percent by weight or to a concentration less than 1 ppmv for each storage vessel vent; or (2) venting emissions through a closed-vent system to a flare meeting the flare operating requirements discussed in section IV.A.1 of the proposal preamble (84 FR 69182, December 17, 2019).</P>
                    <P>To reduce risks from equipment leaks in EtO service, we proposed the following combined requirements: monitoring of connectors in gas/vapor and light liquid service at a leak definition of 100 ppm on a monthly basis with no reduction in monitoring frequency or delay of repair (at 40 CFR 63.174(a)(3) and 40 CFR 63.174(b)(3)(vi)); light liquid pump monitoring at a leak definition of 500 ppm monthly (at 40 CFR 63.163(b)(2)(iv)); and gas/vapor and light liquid valve monitoring at a leak definition of 100 ppm monthly with no reduction in monitoring frequency or delay of repair (at 40 CFR 63.168(b)(2)(iv) and 40 CFR 63.168(d)(5)).</P>
                    <P>To reduce risks from EtO emissions due to heat exchange system leaks, we proposed at 40 CFR 63.104(g)(6) to require weekly monitoring for leaks for heat exchange systems in EtO service using the Modified El Paso Method, and if a leak is found, we proposed at 40 CFR 63.104(h)(6) that owners and operators must repair the leak to reduce the concentration or mass emissions rate to below the applicable leak action level as soon as practicable, but no later than 15 days after the sample was collected with no delay of repair allowed.</P>
                    <P>To reduce risks from wastewater in EtO service, we proposed at 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii) that owners and operators of HON sources manage and treat any wastewater streams that are “in ethylene oxide service.” We also proposed at 40 CFR 63.104(k) to prohibit owners and operators from injecting water into or disposing of water through any heat exchange system in a CMPU meeting the conditions of 40 CFR 63.100(b)(1) through (3) if the water contains any amount of EtO, has been in contact with any process stream containing EtO, or the water is considered wastewater as defined in 40 CFR 63.101.</P>
                    <P>In addition, we proposed at 40 CFR 63.165(e)(3)(v)(D) that any release event from a PRD in EtO service is a violation of the standard to ensure that these process vent emissions are controlled and do not bypass controls. Also, in order to help reduce EtO risk from the SOCMI source category to an acceptable level, we proposed: (1) A requirement at 40 CFR 63.113(k)(4) that owners and operators cannot release more than 1.0 ton of EtO from all maintenance vents combined in any consecutive 12-month period; and (2) a requirement at 40 CFR 63.108(p) that owners and operators can send no more than 20 tons of EtO to all of their flares combined in any consecutive 12-month period from all HON emission sources at a facility.</P>
                    <P>After implementation of the proposed controls for: (1) Process vents, (2) storage vessels, (3) equipment leaks, (4) heat exchange systems, and (5) wastewater “in ethylene oxide service,” as well as implementation of the proposed requirements to reduce EtO emissions from maintenance vents, flares, and PRDs, we proposed that the resulting risks would be acceptable for the SOCMI source category. We determined at proposal that estimated post-control risks would be reduced to 100-in-1 million (down from 2,000-in-1 million) with no individuals exposed to risk levels greater than 100-in-1 million from HAP emissions from HON processes (see section III.B.2 of the proposal preamble, 88 FR 25080, April 25, 2023).</P>
                    <P>
                        We then considered whether the existing MACT standards provide an ample margin of safety to protect public health and whether, taking into consideration costs, energy, safety, and other relevant factors, additional standards are required to prevent an adverse environmental effect. We noted that the EPA previously made a determination that the standards for the SOCMI source category provided an ample margin of safety to protect public health, and that the most significant change since that determination was the revised 2016 IRIS inhalation URE for EtO and new 2010 IRIS inhalation URE for chloroprene. As such, we focused our ample margin of safety analysis on cancer risk for EtO and chloroprene, since these pollutants, even after application of controls needed to get risks to an acceptable level, drive cancer risk and cancer incidence (
                        <E T="03">i.e.,</E>
                         60 percent of remaining cancer incidence is from EtO) for the SOCMI source category. The ample margin of safety analysis for the SOCMI source category identified no other control options for EtO beyond those proposed to reduce risks to an acceptable level. For chloroprene emissions from HON-subject sources, we identified control 
                        <PRTPAGE P="42958"/>
                        options for equipment leaks and maintenance activities; however, the options evaluated were found not to be cost-effective (see sections III.C.6 and III.D.4 of the proposal preamble, 88 FR 25080, April 25, 2023). Therefore, we proposed that the requirements that we proposed to achieve acceptable risk would also provide an ample margin of safety to protect public health (section III.B.3 of the proposal preamble, 88 FR 25080, April 25, 2023).

                        Pursuant to CAA section 112(f), the EPA conducted a residual risk review and presented the results of this review, along with our proposed decisions regarding risk acceptability and ample margin of safety, in the April 25, 2023, proposed rule for the Neoprene Production source category subject to the P&amp;R I NESHAP (88 FR 25080). The results of the risk assessment for the proposal are presented briefly in Table 2 of this preamble. More detail is in the residual risk technical support document,

                    <P>The results of the proposed chronic baseline inhalation cancer risk assessment at proposal indicated that, based on estimates of current actual and allowable emissions, the MIR posed by the source category was 500-in-1 million, driven by chloroprene emissions from maintenance vents (67 percent), storage vessels (11 percent), wastewater (8 percent), and equipment leaks (4 percent). At proposal, the total estimated cancer incidence from this source category was estimated to be 0.05 excess cancer cases per year, or 1 cancer case every 20 years. Approximately 690,000 people were estimated to have cancer risks above 1-in-1 million from HAP emitted from this source category. At proposal, the estimated maximum chronic noncancer TOSHI for the source category was 0.05 for respiratory effects from chloroprene emissions.</P>
                    <P>As shown in Table 2 of this preamble, the worst-case acute HQ at proposal was 0.3 based on the REL for chloroform. In addition, at proposal, we did not undertake the three-tier human health risk screening assessment that was conducted for the SOCMI source category given that we did not identify reported persistent and bioaccumulative HAP (PB-HAP) emissions from the Neoprene Production source category. Instead, at proposal, we noted that we would expect dioxins likely to be formed by combustion controls used to control chlorinated chemicals such as chloroprene from this source category and concluded that risk from dioxins from the Neoprene Production source category would be lower than they are for the SOCMI source category after compliance with the proposed dioxin limit occurs. Also, because we did not identify reported PB-HAP emissions, we did not undertake the environmental risk screening assessment of PB-HAP for the Neoprene Production source category; however, we did conduct an environmental risk screening assessment for acid gases and concluded that no ecological benchmark was exceeded.</P>
                    <P>At proposal, the maximum lifetime individual cancer risk posed by the one neoprene production facility, based on whole-facility emissions, was 600-in-1 million, with chloroprene emissions from maintenance vents (66 percent total, 55 percent from neoprene production sources and 11 percent from HON sources), storage vessels (9 percent total, all from neoprene production sources), equipment leaks (7 percent total, 3 percent from neoprene production sources and 4 percent from HON sources), and wastewater (7 percent, all from neoprene production sources) driving the risk. Regarding the noncancer risk assessment, the maximum chronic noncancer TOSHI posed by whole-facility emissions was estimated to be 0.3 (for respiratory effects) due to chlorine emissions.</P>
                    <P>
                        We weighed all health risk measures and factors, including those shown in Table 2 of this preamble, in our risk 
                        <PRTPAGE P="42959"/>
                        acceptability determination and proposed that the risks posed by the Neoprene Production source category under the current MACT provisions are unacceptable (section III.B of the proposal preamble, 88 FR 25080, April 25, 2023). At proposal, we identified chloroprene as the driver of the unacceptable risk and evaluated several options to control chloroprene emissions from (1) process vents, (2) storage vessels, and (3) wastewater “in chloroprene service.” We also proposed requirements to reduce chloroprene emissions from maintenance vents and PRDs, as well as a facility-wide chloroprene emissions cap for all neoprene production emission sources as a backstop.
                    </P>
                    <P>For process vents, we proposed to define “in chloroprene service” in the P&amp;R I NESHAP at 40 CFR 63.482 to mean each continuous front-end process vent and each batch front-end process vent in a process at affected sources producing neoprene that, when uncontrolled, contains a concentration of greater than or equal to 1 ppmv undiluted chloroprene, and when combined, the sum of all these process vents would emit uncontrolled, chloroprene emissions greater than or equal to 5 lb/yr (2.27 kg/yr).</P>
                    <P>For storage vessels of any capacity and vapor pressure in a process at affected sources producing neoprene, we proposed to define “in chloroprene service” in the P&amp;R I NESHAP at 40 CFR 63.482 to mean that the concentration of chloroprene of the stored liquid is at least 0.1 percent by weight. Additionally, we proposed that unless specified by the Administrator, owners and operators may calculate the concentration of chloroprene of the fluid stored in a storage vessel if information specific to the fluid stored is available such as concentration data from safety data sheets. We also proposed that the exemption for “vessels and equipment storing and/or handling material that contains no organic HAP, or organic HAP as impurities only” listed in the definition of “storage vessel” at 40 CFR 63.482 does not apply for storage vessels in chloroprene service.</P>
                    <P>For wastewater, we proposed to define “in chloroprene service” in the P&amp;R I NESHAP at 40 CFR 63.482 to mean each wastewater stream that contains total annual average concentration of chloroprene greater than or equal to 10.0 ppmw at any flow rate.</P>
                    <P>To reduce risks from process vents in chloroprene service, we proposed requirements at 40 CFR 63.485(y)(1) and 40 CFR 63.487(j)(1) to reduce emissions of chloroprene by either venting emissions through a closed-vent system to a non-flare control device that reduces chloroprene by greater than or equal to 99.9 percent by weight or to a concentration less than 1 ppmv for each process vent, or to less than 5 lb/yr for all combined process vents.</P>
                    <P>To reduce risks from storage vessels in chloroprene service, we proposed a requirement at 40 CFR 63.484(u)(1) to reduce emissions of chloroprene by either venting emissions through a closed-vent system to a non-flare control device that reduces chloroprene by greater than or equal to 99.9 percent by weight or to a concentration less than 1 ppmv for each storage vessel.</P>
                    <P>To reduce risks from wastewater in chloroprene service, we proposed at 40 CFR 63.501(a)(10)(iv) that owners and operators of P&amp;R I sources producing neoprene manage and treat any wastewater streams that are “in chloroprene service.” We also proposed at 40 CFR 63.502(n)(8) to prohibit owners and operators from injecting water into or disposing of water through any heat exchange system in an EPPU if the water contains any amount of chloroprene, has been in contact with any process stream containing chloroprene, or the water is considered wastewater as defined in 40 CFR 63.482.</P>

Also, in order to help reduce chloroprene risk from the Neoprene Production source category to an acceptable level, we proposed: (1) A requirement at 40 CFR 63.485(z) and 40 CFR 63.487(i)(4) that owners and operators cannot release more than 1.0 ton of chloroprene from all maintenance vents combined in any consecutive 12-month period; and (2) a facility-wide chloroprene emissions cap at 40 CFR 63.483(a)(10) that owners and operators cannot release more than 3.8 tpy in any consecutive 12-month period from all neoprene production emission sources, combined.</P>
                    <P>After implementation of the proposed controls for: (1) Process vents, (2) storage vessels, and (3) wastewater “in chloroprene service,” as well as implementation of the proposed requirements to reduce chloroprene emissions from maintenance vents, PRDs, and all neoprene production emission sources, combined, we proposed that the resulting risks would be acceptable from HAP emissions from the Neoprene Production source category. We determined at proposal that estimated post-control risks would be reduced to 100-in-1 million (down from 500-in-1 million) with no individuals exposed to risk levels greater than 100-in-1 million (see section III.B.2 of the proposal preamble, 88 FR 25080, April 25, 2023) from neoprene production emission sources.</P>
                    <P>
                        We then considered whether the existing MACT standards provide an ample margin of safety to protect public health and whether, taking into consideration costs, energy, safety, and other relevant factors, additional standards are required to prevent an adverse environmental effect. We noted that the EPA previously made a determination that the standards for the Neoprene Production source category provided an ample margin of safety to protect public health, and that the most significant change since that determination was the new 2010 IRIS inhalation URE for chloroprene. As such, we focused our ample margin of safety analysis on cancer risk for chloroprene since this pollutant, even after application of controls needed to get risks to an acceptable level, drives cancer risk and cancer incidence (

                         99.995 percent of remaining cancer incidence is from chloroprene) for the Neoprene Production source category. To determine whether the rule provides an ample margin of safety, we considered the chloroprene specific requirements that we proposed to achieve acceptable risks, as well as additional control requirements for chloroprene. The ample margin of safety analysis found that additional chloroprene controls would not be cost-effective, and therefore, we proposed that the requirements that we proposed to achieve acceptable risk would also provide an ample margin of safety to protect public health (section III.B.4 of the proposal preamble, 88 FR 25080, April 25, 2023).

                    <P>In response to comments received on the proposed rulemaking, we revised the risk assessments for the SOCMI and Neoprene Production source categories.

The following sections provide the results of the revised risk assessments.</P>

                    <P>
                        In response to a comment in section 1.1 of the document titled Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry, which is available in the docket for this rulemaking, we modified our approach to modeling flares for the SOCMI source category and performed a revised risk assessment of baseline risk (
                        <E T="03">i.e.,</E>
                         risk prior to the implementation of the control requirements described in this final action). Based on this revised risk assessment, the baseline MIR risk posed by the source category is 2,000-in-1 million driven by EtO emissions from PRDs (74 percent) and equipment leaks (20 percent). The total estimated cancer incidence due to emissions from this source category is estimated to be 2 excess cancer cases per year. Within 50 km (~31 miles) of HON-subject facilities, the population exposed to cancer risk greater than 100-in-1 million for HON actual and allowable emissions is approximately 83,000 people, and the population exposed to cancer risk greater than or equal to 1-in-1 million is approximately 7.17 million people. Of the 195 facilities that were assessed for risk, 8 facilities have an estimated maximum cancer risk greater than 100-in-1 million. In addition, the maximum modeled chronic noncancer TOSHI for the source category based on actual and allowable emissions is estimated to be 2 (for respiratory effects) at two different facilities (from maleic anhydride emissions at one facility and chlorine emissions at another facility). Approximately 83 people are estimated to be exposed to a TOSHI greater than 1. We note that the only change in these results from the proposal is the number of people exposed to cancer risk greater than 100-in-1 million for HON emissions, which decreased from 87,000 people at proposal to 83,000 people here. See Table 3 of this preamble for a summary of the HON baseline inhalation risk assessment results.

                    <P>
                        We conducted a revised assessment of facility-wide (or “whole-facility”) risk to characterize the source category risk in the context of whole-facility risk. The maximum lifetime individual cancer risk posed based on whole-facility emissions is 2,000-in-1 million with EtO emissions from PRDs (74 percent) and equipment leaks (20 percent) from SOCMI source category emissions driving the risk. The total estimated cancer incidence based on facility-wide emission levels is 2 excess cancer cases per year. Within 50 km (~31 miles) of HON-subject facilities, the population exposed to cancer risk greater than 100-in-1 million for HON facility-wide emissions is approximately 90,000 
                        <PRTPAGE P="42961"/>
                        people, and the population exposed to cancer risk greater than or equal to 1-in-1 million is approximately 8.92 million people. The maximum chronic noncancer TOSHI posed by whole-facility emissions is estimated to be 4 (for respiratory effects) due mostly (98 percent) to emissions from 2 facilities. Emissions from one facility contribute to 83 percent of the TOSHI, with approximately 60 percent of the total TOSHI from non-source category emissions of chlorine and another 15 percent from source category emissions of chlorine. Emissions from the second facility contribute to 15 percent of the TOSHI, with approximately 11 percent of the total TOSHI from source category emissions of acrylic acid and 2 percent from source category emissions of acrylonitrile. Approximately 1,100 people are estimated to be exposed to a TOSHI greater than 1 due to whole-facility emissions. Again, we note that the only change in these results from the proposal is the number of people exposed to cancer risk greater than 100-in-1 million, which decreased from 95,000 people at proposal to 90,000 people here (due to our modified approach to modeling flares, discussed above).

                    <P>
                        Finally, we conducted a revised assessment to evaluate risks after implementation of the control requirements described in this action. After implementation of the controls, the MIR for the SOCMI source category is reduced to 100-in-1 million (down from 2,000-in-1 million) with no individuals exposed to risk levels greater than 100-in-1 million from HAP emissions from the SOCMI source category, which is the same as in the proposal. The total population exposed to risk levels from the SOCMI source category greater than or equal to 1-in-1 million living within 50 km (~31 miles) of a facility would be reduced from 7.17 million people to 6.27 million people. The cancer incidence would be reduced from 2 excess cancer cases per year to 0.4 excess cancer cases per year. The maximum modeled chronic noncancer TOSHI for the source category remains unchanged. Specifically, the chronic noncancer TOSHI is estimated to be 2 (for respiratory effects) at two different facilities (from maleic anhydride emissions at one facility and chlorine emissions at another facility) with approximately 83 people estimated to be exposed to a TOSHI greater than 1. The estimated worst-case off-site acute exposures to emissions from the SOCMI source category also remains unchanged, with a maximum modeled acute HQ of 3 based on the RELs for chlorine and acrolein. The only change in these results from proposal is the number of people exposed to cancer risk levels greater than or equal to 1-in-1 million (6.27 million here compared to 5.7 million at proposal) due to us not finalizing (in response to persuasive comments received during the public comment period) the requirement at 40 CFR 63.108(p) that would prohibit owners and operators from sending more than 20 tons of EtO to all of their flares combined in any consecutive 12-month period (for more information on this, see Section IV.A.3.d.v of this preamble). Table 4 of this preamble summarizes the reduction in risks due to emissions from the SOCMI source category based on the controls in this action. For further details on the revised risk assessment for the SOCMI source category, see the document titled

                        Table 4 of this preamble also summarizes the facility-wide risks for facilities in the SOCMI source category. The post-control facility-wide MIR remains 2,000-in-1 million, driven by EtO emissions from Polyether Polyols Production source category emissions sources, which the EPA intends to address in a future action. Further, we note that the fenceline monitoring action level of 0.2 μg/m
                        <SU>3</SU>
                         for EtO will reduce EtO emissions and therefore risks below these levels, with the MIR reduced to 1,000-in-1 million or lower and the number of individuals exposed to cancer risk levels greater than 100-in-1 million and greater than or equal to 1-in-1 million expected to be lower than those in Table 4 of this preamble.

                        In response to a comment in section IV.A.3.e.i of this preamble, we revised the performance standard for process vents and storage vessels in chloroprene service for the Neoprene Production source category. This revision did not change the baseline source category or facility-wide risk assessments for the Neoprene Production source category from proposal (see section IV.A.1.b of this preamble and Table 5 of this preamble). The revised assessment indicated that, after implementation of the controls, the MIR for the Neoprene Production source category is 100-in-1 million (down from 500-in-1 million in the pre-control baseline) with no individuals exposed to risk levels greater than 100-in-1 million from HAP emissions from the Neoprene Production source category. This result is the same as in the proposal. The total population exposed to risk levels from the Neoprene Production source category greater than or equal to 1-in-1 million would be reduced from 690,000 people to 58,000 people. The total estimated cancer incidence of 0.05 drops to 0.01 excess cancer cases per year. For the risk results estimated after implementation of controls, the two changes from proposal are the number of people exposed to risk levels greater than or equal to 1-in-1 million (58,000 here compared to 48,000 at proposal) and the cancer incidence (0.01 here compared to 0.008 at proposal) from HAP emissions from the Neoprene Production source category. All other results remained the same. Table 5 of this preamble summarizes the reduction in cancer risks due to emissions from the Neoprene Production source category based on the controls in this action.

                         Commenters objected to the use of the 2017 National Emissions Inventory (NEI) data without corrections or revisions to model risk. These commenters requested that the EPA incorporate all of the revisions that were provided by various companies that participated in the EPA's January 18, 2022, CAA section 114 request. A commenter explained that the EPA allowed facilities to update emissions values so the EPA's assessment was representative of current operations and improvements to both emissions controls and emissions estimation methodologies. The commenter pointed out that although several facilities provided revisions to the EPA for their NEI modeling file inputs, the EPA rejected many of them. The commenter contended that if the EPA corrected its emissions modeling file to reflect more accurate emissions levels or upgraded emissions controls, it would determine, for a number of facilities, that risks were acceptable, or some emissions units were not meaningfully contributing to risk.

                    <P>Commenters provided the following specific examples of corrections facilities made to their 2017 NEI data, but were rejected by the EPA:</P>

                    <P>By incorporating the above revisions, commenters insisted the residual risk attributable to EtO would be reduced and the EPA would conclude that risks are acceptable, even if the current IRIS value for EtO is used.</P>
                    <P>A different commenter asserted that the EPA cannot rely on a single year of emissions data from HON and P&amp;R I sources to evaluate residual risk. The commenter explained that the NEI does not provide a reliable basis for estimating downwind concentrations of specific HAPs and the resulting cancer or noncancer risk to the communities nearby. The commenter said that, by the EPA's conclusions, fenceline monitoring data has shown that modeled concentrations greatly underestimate monitored concentrations. The commenter contended that the reliance on 2017 NEI data would contradict the EPA's own statements and would not provide the ample margin of safety that the CAA requires. While the NEI can be used as a starting point, the commenter recommended that the EPA should select the highest annual emissions that each source has reported to either the Toxics Release Inventory (TRI) or the NEI within the most recent five-year period for which data are available. The commenter explained that TRI reports are filed annually and may provide a more accurate picture of current emissions, and it would be irrational to base a residual risk assessment for sources on the 2017 NEI when the same sources are reporting higher emissions in the 2017-2021 TRI or 2020 NEI reports.</P>
                    <P>
                        Similarly, a commenter objected to the EPA's use of the 2019 baseline actual emissions for Denka Performance Elastomers, LLC to assess residual risk of chloroprene emissions. The commenter said that the 2019 baseline actual emissions are substantially lower than historic actual emission levels reported to the Louisiana Department of Environmental Quality (LDEQ) from 1991 through 2017; and the EPA's risk report does not appear to include a description of the primary causes for the observed 2019 emission reductions. The commenter added that the combined average 2019 community monitored chloroprene concentration is 2.5 times the EPA's 2019 modeled average fenceline concentration (0.74 μg/m
                        <SU>3</SU>
                        ). The commenter also asserted that the 2019 actual annual baseline emissions do not reflect sustainable chloroprene emission reductions achieved through work practice standards or application of MACT emission controls given that the average chloroprene concentration measured at 5th Ward Elementary during the first 6 months of 2020 were 
                        <PRTPAGE P="42965"/>
                        ~52 percent higher than the measured 2019 concentrations.

                         We disagree with commenters who object to the use of the 2017 NEI data. We relied on the January 2021 version of the 2017 NEI dataset because it provided the best available data for EtO emissions and other HAP emissions for the SOCMI source category and the Neoprene Production source category covered under the P&amp;R I NESHAP. However, in a few instances where facility-specific data were not available or not reflective of current controls in the 2017 NEI, we attempted to obtain data from a more recent dataset (
                        <E T="03">e.g.,</E>
                         review of emissions inventory data from our CAA section 114 request, more recent inventories submitted to states, or the 2018 NEI). Where we did not have better data, we did not update our dataset. Of note, for the one neoprene production facility (which is also part of the SOCMI source category), we used the 2019 emissions inventory that was provided to the EPA from our CAA section 114 request. The NEI data were also used to develop the other parameters needed to perform the risk modeling analysis, including the emissions release characteristics, such as stack heights, stack diameters, flow rates, temperatures, and emission release point locations.
                    </P>
                    <P>
                        We note that the EPA has an obligation to use the best available data for establishment of risk-based standards and generally updates the dataset where we have sufficient rationale or improved data (
                        <E T="03">e.g.,</E>
                         relevant stack test data, documented process concentrations), but the EPA has discretion to reject updated emissions estimates when insufficient rationale and information is provided. In general, we rejected the corrections facilities made to their 2017 NEI data (
                        <E T="03">i.e.,</E>
                         the corrections listed by commenters as specified in this comment summary) due to insufficient information when numbers were updated without a clear or substantive explanation of why emissions changed and where EPA could not fully verify the changes. For example, many suggested changes were due to revisions in the engineering calculation methods with no documented detailed calculations shown. Other examples include changing calculation input assumptions for the amount of HAP in process streams where no source testing/sampling was provided by commenters to support their suggested changes. Further, in many cases we also rejected corrections listed by commenters related to pollutants that drive cancer risks for HON (
                        <E T="03">i.e.,</E>
                         EtO) and neoprene production sources (
                        <E T="03">i.e.,</E>
                         chloroprene) given that we contend, based on the fenceline data, that the modeling file emissions for these pollutants are underestimated.
                    </P>
                    <P>
                        Regarding the commenter's objection to the EPA's use of the 2019 baseline actual emissions for Denka Performance Elastomers, LLC to assess residual risk of chloroprene emissions, the facility's emissions inventory was provided to the EPA pursuant to our CAA section 114 request. In particular, the EPA requested emission inventories from the past 5 years (
                        <E T="03">i.e.,</E>
                         2016-2020) from the facility's operations as part of this request. As 2017 NEI data did not represent current controls being employed at Denka Performance Elastomers, LLC, the EPA chose to use the most current data it had available, which is reflective of current operations and emissions. Given the EPA's concerns about decreased production and emissions in 2020 from the COVID-19 pandemic, we elected to use Denka Performance Elastomer, LLC's 2019 emissions inventory submitted as part of the CAA section 114 request in its risk assessment for the HON and Neoprene Production source categories in lieu of the 2017 NEI data. The EPA also reviewed chloroprene emission records to determine whether the emissions were associated with HON processes, neoprene processes, or other non-HON and non-neoprene processes and updated the regulatory code in the risk modeling input files to account for this review.
                    </P>
                    <P>
                        In summary, we took many steps to develop an emissions modeling file that was representative of emissions from HON and P&amp;R I sources, including declining to revise data where we had insufficient rationale or information to verify commenters' suggested changes. As described in more detail in the preamble to the proposed rulemaking (88 FR 25080, April 25, 2023), the EPA used many sources of information to develop the HAP emissions inventory used to assess risks for this rulemaking, including, but not limited to, the 2017 NEI and information gathered under our CAA section 114 authority. The EPA typically has wide latitude in determining the extent of data-gathering necessary to solve a problem and courts generally defer to the agency's decision to proceed on the basis of imperfect scientific information, rather than to “invest the resources to conduct the perfect study.”

                         A commenter contended that the EPA's inclusion of infrequent, episodic events in their risk assessment is inappropriate. The commenter explained that short-term or one-time emissions release events are not representative of concentrations an individual would be exposed to over a lifetime. Furthermore, the commenter contended that the EPA should also have excluded EtO emissions related to SSM events from its voluntary risk analysis because the EPA is statutorily obligated to address SSM events under CAA sections 112(d)(2) and (d)(3).

                         If any operating period (including SSM periods) leads to noncompliance with standards, we would not model such noncompliance for purposes of assessing risk in the CAA section 112(f) risk review because the agency estimates risk based on compliance with the established NESHAP. The statute does not require the agency to determine risk based on some assumed level of noncompliance. In addition, the appropriate remedy for noncompliance with a NESHAP is an enforcement action seeking to require the source to come into compliance with the standard.

                        Emissions events in violation of the standards, whether or not they are caused by malfunction events, are not considered as part of risk analyses. The EPA interprets CAA section 112 as not requiring emissions that occur during periods of malfunction to be factored into development of CAA section 112 standards, and this reading has been upheld as reasonable by the U.S. Court of Appeals for the District of Columbia in

                         830 F.3d 579, 606-10 (D.C. Cir. 2016). Consistent with previous risk assessments, the EPA considered both allowable and actual emissions in assessing chronic inhalation exposure and risk under CAA section 112(f)(2) for the SOCMI source category and the Neoprene Production source category covered under the P&amp;R I NESHAP (see,

                         the National Emission Standards for Coke Oven Batteries [70 FR 19998-19999, April 15, 2005] and the proposed and final HON (71 FR 34428, June 14, 2006 and 71 FR 76603, December 21, 2006, respectively)). The final rule is designed to require sources to comply during all periods of operation. As explained in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023), it is not generally possible to model malfunctions in the risk assessment, because by nature they are infrequent and unpredictable, and we generally have insufficient information to model these types of events. The main purpose of the risk review for these source categories is to evaluate whether the emission limits—the “standards promulgated pursuant to subsection (d),” not the non-compliance with those standards—should be made more stringent to reduce the risk posed after compliance with the underlying MACT standards. To the extent that a source is violating an underlying MACT standard, it is unlikely that tightening of the emission standard as a result of the residual risk review will avoid or mitigate such violations. In other words, a source that is violating a MACT emissions standard promulgated under CAA section 112(d) would not be any more likely to be able to avoid such violations and comply with a different presumably more stringent standard promulgated under CAA section 112(f). Such events are violations and subject to enforcement by the EPA, the states, or citizens, and an action for injunctive relief is the most effective means to address violations, whether or not they are caused by malfunctions, if an emissions event poses a significant health or environmental risk.

                        The EPA notes that the final Petroleum Refinery Sector Rule included a conservative, screening-level assessment (not a refined risk assessment) performed using available information collection response (ICR) data to see the impacts of certain non-routine emissions events from PRDs and flares. [80 FR 75178, December 1, 2015] That assessment conservatively combined routine and non-routine emissions merely to define an upper bound of combined risk, and the EPA ultimately concluded that risks were not significantly different, given the uncertainties and conservative nature of the screening. In this risk assessment, the EPA did have information on EtO emissions from PRD events at one facility as they were reported to the Texas Commission on Environmental Quality (TCEQ). The modeling indicated that emissions from one single PRD release contributed to the majority of the cancer risk for that facility and as such we proposed and are finalizing requirements that any releases from PRD in EtO service are violations of these emission standards. The EPA did not include other additional emission estimates from non-routine PRD or flare events in the emissions inventory that was used to assess residual risk. Other than for highly toxic compounds such as EtO and chloroprene, we have found that non-routine emissions from PRDs and flares in similar source categories, including ethylene production facilities and petroleum refineries, have not significantly affected risks (see,

                         Commenters asserted that the EPA should continue to place environmental justice at the forefront as it moves through the regulatory process and ensure it takes steps to reduce impacts on overburdened communities. A commenter pointed out that populations with lung disease, children, people with heart disease, and others are typically at higher risk of health harm from air pollution. The commenter declared that the EPA must place a priority on ensuring the current administration meets its goals on improving environmental justice, ensuring that people who live near these facilities do not continue to face overlapping health inequities that increase their overall risk. Other commenters called attention to the 7 million people who live near chemical plants who face serious cancer risk from uncontrolled toxic air emissions and are majority Black and Brown residents. Commenters stated that chemical manufacturing facilities are commonly located in communities of color and low-income neighborhoods (especially in Texas and Louisiana) and the emissions reductions from the proposed standards will help reduce the burden on disproportionately impacted communities.

                    <P>Another commenter asserted that the EPA should strengthen the proposed HON standards to further reduce HAP emissions with the goal of eliminating racial disparities in exposure at all risk levels. The commenter claimed that, even after adoption of the proposed rule, about 1.6 million people of color will still face serious cancer risk at the 1-in-1 million level simply by living within 10 km (6.2 miles) of toxic air emissions emitted by regulated sources from chemical manufacturing plants. The commenter contended that the EPA succeeded at identifying environmental justice concerns, however it failed to address these concerns. The commenter cited the EPA's environmental justice web page, specifically the phrase “no group of people should bear a disproportionate share of the negative environmental consequences,” and stated that people of color will still bear a disproportionate share of exposure to HAPs and resulting cancer risk if the HON rule is adopted as proposed. Furthermore, the commenter contended that the EPA failed to cite and analyze the scientific evidence that shows that people of color are also uniquely susceptible to the health effects of toxic air pollutants, in addition to being more highly exposed, due to the cumulative impacts from a combination with other psycho-social stressors including racism, poverty, lack of access to health care and healthful foods.</P>

                         The EPA is directed, to the greatest extent practicable and permitted by law, to make environmental justice part of its mission by identifying and addressing, as appropriate, disproportionate and adverse human health or environmental effects of its programs, policies, and activities on communities with environmental justice concerns. The EPA's environmental justice policies promote justice, including access to health impact data, by providing information on the types of environmental justice harms and risks that are prevalent in communities with environmental justice concerns. No such policies mandate consideration of any specific factors or particular outcomes from an action, but they direct that environmental justice analysis be performed as part of regulatory impact analysis, as appropriate, so that the public can have this information. As noted above, the assessment of costs and benefits described herein and in the RIA, including the environmental justice analysis, is presented for the purpose of providing the public with as full as possible an understanding of the potential impacts of this final action. The EPA notes that analysis of such impacts is distinct from the determinations finalized in this action under CAA sections 111 and 112, which are based solely on the statutory factors the EPA is required to consider under those sections.

In addition to evaluating risk distribution, this analysis also presents the demographic composition of the population located within close proximity (10 km) and within the overall HEM/AERMOD model domain (50 km) of the source category emissions (irrespective of risk).

                    <P>Considering risk, the post-control scenario is expected to reduce cancer incidence across all demographic groups including communities of environmental justice concern. Regarding the commenter's concern about the post-control risk exposure of people of color, the requirements for the HON/SOCMI facilities reduce the chronic cancer risks for Black individuals as follows: &gt;100-in-1 million from 12,000 people to zero people; ≥50-in-1 million from 59,000 to 4,000; and ≥1-in-1 million from 694,000 to 692,000. The rule has the greatest impact at the higher chronic cancer risk levels. Additionally, regarding concern about the unique susceptibility of people of color to the health impacts of toxic air pollutants, the EPA is currently exploring data and methods to make it possible to more explicitly evaluate the role of non-chemical stressors in an environmental justice analysis.</P>

                        Some commenters supported the EPA expanding the community-based risk assessment to include air toxics-related cancer risks from all large facilities in communities in the vicinity, including sources that would not be covered by the rule. The commenters explained that since the public's exposure is not limited to one chemical or source category at a time, this is a step in the right direction. The commenters suggested these expanded community-based risk assessments be standard practice. Other commenters proposed to expand the community-based risk assessment to not only include all large facilities in the area, but also include other types of sources (

                         miscarriages, birth defects, neurodevelopmental impacts), and explore other routes of exposure beyond inhalation. Commenters claimed this could be accomplished if the EPA went a step further than the community risk assessment and performed a cumulative risk assessment. The commenter explained that a cumulative risk assessment would take into account chemical and non-chemical stressors, and how these stressors interact to promote adverse health effects.

A commenter claimed that, under the proposed rule, about 5.7 million people would still face serious cancer risk at the 1-in-1 million level simply by living within 50 km (31 miles) of toxic air emissions that are being emitted by regulated sources from chemical manufacturing plants. The commenter further claimed that, by living within 10 km (6.2 miles), there is only a 10 percent reduction of total people at this risk level. The commenter contended that the EPA has done more in the past, specifically when 99 percent of the population living within 50 km had cancer risk reduced to 1-in-1 million through the Benzene NESHAP rule.</P>
                    <P>On the contrary, a commenter argued that the EPA's “whole-facility” and “community-based” risk assessments are irrelevant to the proposed rule because the EPA is limited to considering only risks associated with the source category that is the subject of the risk assessment.

                         We appreciate the commenters' support of the community-based risk assessment. In response to reducing the number of people exposed at or above 1-in-1 million cancer risk to the maximum extent feasible, the EPA's ample margin-of-safety determinations are conducted in accord with the two-step framework set forth in the Benzene NESHAP. When making its ample margin of safety determination, the EPA does consider health risks and their associated uncertainties, but also considers costs, technical feasibility, and other factors. For the SOCMI source category, in Step 1 of the Benzene NESHAP framework, the risks were determined to be unacceptable given all of the health information. Standards were proposed to bring the risk down to acceptable levels, not considering costs. Once the risks were determined to be at acceptable levels, Step 2 of the Benzene NESHAP framework requires the EPA to again consider health risks, but also cost, technical feasibility, and other factors, in determining if any additional controls should be required to achieve an ample margin of safety. For the SOCMI source category, the EPA proposed that it was not appropriate to require additional controls (either based on costs, feasibility, or availability) beyond what were proposed to achieve acceptable risks, regardless of health risks, thus we concluded that the proposed standards to address unacceptable risks also achieved an ample margin of safety.

                         Some commenters asserted that the community-based risk assessments should be used when making regulatory decisions, although there may be implementation challenges due to potential limitations in the EPA's statutory authority. A commenter explained that the CAA requires the EPA to investigate whether its regulations provide an “ample margin of safety” to protect public health, and if a community risk assessment demonstrates that a proposed rule does not provide an “ample margin of safety” (because of other health stressors in the community not captured by other risk assessments), then the EPA should revise the proposed rule.

                         Section 112(f)(2) of the CAA expressly preserves our use of the two-step process for developing standards to address residual risk and interpret “acceptable risk” and “ample margin of safety” as developed in the Benzene NESHAP (54 FR 38044, September 14, 1989). In the Benzene NESHAP, the EPA concluded that “With respect to considering other sources of risk from benzene exposure and determining the acceptable risk level for all exposures to benzene, EPA considered this inappropriate because only the risk associated with the emissions under consideration are relevant to the regulation being established and, consequently, the decisions being made.” (54 FR 38044, September 14, 1989). Our authority to use the two-step process set forth in the Benzene NESHAP, and to consider a variety of measures of risk to public health, is discussed more thoroughly in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023). Nothing in the CAA or the Benzene NESHAP in any way forecloses us from considering facility-wide risks in making a determination under CAA section 112(f)(2), as such information can constitute relevant health information.

                    <P>Although not appropriate for consideration in the determination of acceptable risk presented by just source category emissions, we note that contributions to risk from sources outside the source category under review could be one of the relevant factors considered in the ample margin of safety determination, along with cost and economic factors, technological feasibility and other factors. For the SOCMI source category, the EPA proposed that it was not appropriate to require additional controls (either based on costs, feasibility, or availability) beyond what were proposed to achieve acceptable risks, regardless of health risks, thus we concluded that the proposed standards to address unacceptable risk posed by emissions from the SOCMI source category also achieved an ample margin of safety.</P>
                    <P>The development of community-based estimates provides additional information about the potential cumulative risks in the vicinity of the RTR sources, as one means of informing potential risk-based decisions about the RTR source category in question. We recognize that, because these risk estimates were derived from facility-wide emissions estimates which have not generally been subjected to the same level of engineering review as the source category emission estimates, they may be less certain than our risk estimates for the source category in question, but they remain important for providing context as long as their uncertainty is taken into consideration in the process.</P>

Some commenters said that the EPA's refusal to consider costs of the controls proposed to reduce EtO emissions is beyond the EPA's statutory authority, and is arbitrary and capricious. The commenters said that unless specifically instructed otherwise, rational decision making requires the consideration of cost. The commenters contended that unless a statute precludes consideration of costs, “[c]onsideration of cost reflects the understanding that reasonable regulation ordinarily requires paying attention to the advantages and the disadvantages of agency decisions.”

A commenter opined that because it would be “unreasonable to read an instruction to an administrative agency to determine whether `regulation is appropriate and necessary' as an invitation to ignore costs,” similarly, it would be unreasonable here for the EPA to ignore costs after it discretionally determined that it was “necessary” to “revisit and revise” the residual risk threshold.

                    <P>The commenters said the residual risk provisions, by reference to the Benzene NESHAP, allow the EPA to exclude costs only in initially determining acceptable risk, but in setting an ample margin of safety, costs are to be considered. The commenters contended that if the EPA has authority to conduct subsequent residual risk findings (which the commenters dispute), then the entire exercise is a secondary one that must take cost into consideration. A commenter explained that under most circumstances under CAA section 112, even when as an initial step, consideration of cost may be prohibited, the CAA requires consideration of cost in subsequent steps and Congress has constrained circumstances under which cost cannot be considered; therefore, the EPA is acting contrary to Congressional intent by attempting to expand its authority to conduct a risk review more than once, which is the only way in which the EPA could attempt to revise the NESHAP without considering costs.</P>

                         The EPA disagrees that it was unconditionally obligated to consider costs in this CAA section 112(f)(2) risk review. As explained in response to a comment in section 1.5 of the document titled

                         which is available in the docket for this rulemaking, the EPA has the authority to conduct an additional risk review, particularly where new information has come to light making a prior risk review unreliable. New information became available about both chloroprene and EtO in 2010

                        <FTREF/>
                         respectively. After the EPA completed development of the IRIS inhalation URE for chloroprene in 2010 and updated the IRIS inhalation URE for EtO in 2016, the EPA learned that chloroprene and EtO were more toxic than previously known. These updates came after the first risk reviews were conducted for the SOCMI and Neoprene Production (within the P&amp;R I NESHAP) source categories and therefore prompted the EPA to reevaluate residual cancer risks caused by EtO and chloroprene emissions.

                        This reevaluation meant that reconsideration of our original decisions under CAA section 112(f)(2) for the SOCMI and Neoprene Production source categories is warranted, beginning with whether the existing standards reduce risks to acceptable levels under the Benzene NESHAP. Under the Benzene NESHAP, this meant going through 
                        <E T="03">both</E>
                         the (1) acceptability and (2) ample margin of safety steps of the section 112(f)(2) analysis. Only by going through both analytical steps anew could the EPA account for the corrected scientific understanding of risks from these HAP and conduct the appropriately updated residual risk reviews.
                    </P>
                    <P>Under the approach outlined in the Benzene NESHAP, National Emissions Standards for Hazardous Air Pollutants: Benzene Emissions from Maleic Anhydride Plants, Ethylbenzene/Styrene Plants, Benzene Storage Vessels, Benzene Equipment Leaks, and Coke By-Product Recovery Plants (54 FR 38,044, September 14, 1989), the EPA evaluates residual risk and develops standards under CAA section 112(f)(2) in two steps, as some commenters correctly stated. See Proposed Rule, 88 FR at 25,089. In step (1), the EPA determines whether risks are acceptable “consider[ing] all health information, including risk estimation uncertainty, and includes a presumptive limit on maximum individual lifetime [cancer] risk (MIR) of approximately 1 in 10 thousand.” 54 FR at 38,045. If risks are unacceptable, the EPA must determine the emissions standards required to reduce risk to an acceptable level without considering costs. In step (2), the EPA considers whether the emissions standards provide an “ample margin of safety” to protect public health “in consideration of all health information, including the number of persons at risk levels higher than approximately 1 in 1 million, as well as other relevant factors, including costs and economic impacts, technological feasibility, and other factors relevant to each particular decision.” Id. (emphasis added). The EPA must then promulgate or revise emission standards necessary to provide an ample margin of safety to protect public health or determine that the standards being reviewed provide an ample margin of safety without any revisions. After conducting the ample margin of safety analysis, we consider whether a more stringent standard is necessary to prevent, taking into consideration costs, energy, safety, and other relevant factors, an adverse environmental effect.</P>

                        It is true that CAA section 112(f)(2) does not contain words declaring that consideration of costs in assessing risk acceptability is prohibited. However, this Benzene NESHAP approach was incorporated by Congress into CAA section 112(f)(2) in the 1990 CAA amendments and was upheld by the United States Court of Appeals for the District of Columbia Circuit.

                        The new information gained by the 2010 chloroprene and 2016 EtO IRIS inhalation UREs warranted a complete re-analysis of both steps for the HON and Neoprene Production rules. The EPA therefore started back at step (1), acceptability, in which costs are not considered. Starting back at step (1) was essential to ensure that the risks due to EtO and chloroprene were being adequately addressed given the EPA's new understanding that exposure to EtO and chloroprene poses greater risk than was previously known. The EPA could not simply adjust the risk review at the step (2) ample margin of safety analysis to correct any errors and account for the new understanding. As explained elsewhere in this preamble, the EPA has analyzed acceptability of risks from HON and Neoprene Production processes under step (1) and identified controls necessary to achieve acceptability. Moreover, the EtO and chloroprene emission standards for HON and Neoprene Production processes that the EPA is promulgating are all necessary to reduce risks from HAP emissions from the SOCMI and Neoprene Production source categories to acceptable levels, and the EPA is not adopting further source category-

                        specific emission standards under CAA section 112(f)(2) under step (2) of the Benzene NESHAP. Consequently, the EPA does not agree that the cases commenters cited require that the EPA must or even can consider costs in determining these risk acceptability-based standards for process emissions from these source categories.

                         A commenter argued that the EPA should not be carrying out a cost-blind residual risk review for chloroprene when other options to address air toxics risks are available that do take costs into consideration. The commenter pointed out that on May 6, 2021, the EPA's Office of Inspector General (OIG) issued Report No. 21-P-0129: EPA Should Conduct New Residual and Technology Reviews for Chloroprene- and Ethylene July 7, 2023, 61 Oxide-Emitting Source Categories to protect Human Health (“OIG Report”). The commenter said that the EPA's Office of Air and Radiation (OAR) submitted three responses to the OIG Report in which they reiterated: (1) That they are not statutorily required to conduct another residual risk review of chloroprene and (2) that they have multiple options to address risks associated with chloroprene that do not require a cost-blind residual risk review. The commenter stated that OAR explained to OIG that it can consider risks during a technology review and that the EPA has “multiple tools available under the CAA for addressing risk from emissions of air toxics” besides discretionary residual risk reviews under CAA section 112(f).

                        As OAR stated in the above response, there are multiple tools available to “address” risk from emissions of air toxics, and OAR said it would evaluate those tools, which may include a CAA section 112(d)(6) review. But the EPA did not say that it commonly “considers” risk in a CAA section 112(d)(6) review, or that risk is a factor that must drive a regulatory decision under CAA section 112(d)(6). The EPA considers the public health and environmental risks from HAP emissions during the CAA section 112(f) phase of regulation, when the EPA considers any residual risk after technology-based CAA section 112(d)(2) standards are implemented. However, when the EPA revises standards under CAA section 112(d)(6) and imposes additional controls or work practice standards that lead to HAP emission reductions, risk from those HAP emission reductions is inherently 
                        <E T="03">addressed</E>
                         to some degree given that reduced emissions will correlate to some degree of reduced risk. While the EPA does not have to directly 
                        <E T="03">consider</E>
                         risk in the CAA section 112(d)(6) analysis, risks are lowered when additional emission controls are imposed as a result of those standards.
                    </P>
                    <P>
                        However, in the case of the SOCMI and Neoprene Production standards, the risks were so significantly affected by the IRIS values for EtO and chloroprene that it became clear that a full risk review under CAA section 112(f)(2) was warranted, rather than relying on ancillary risk benefits that might result from conducting only a CAA section 112(d)(6) technology review. Consequently, under the Benzene NESHAP approach incorporated by CAA section 112(f), as explained above, we had to re-assess whether the existing standards were sufficiently protective, and we determined that they did not reduce risks to acceptable levels. The standards adopted in the final rulemaking are based on what is necessary to reduce risks to acceptable levels under the Benzene NESHAP, and therefore may not be based on consideration of costs. However, our rulemaking analyses do estimate the costs that will result from compliance with the standards, even if that information did not drive regulatory decisions.

                         A commenter argued that the Agency arbitrarily fails to properly implement the authority it claims to possess. The commenter pointed out that the EPA does not limit its review to chloroprene and EtO (
                        <E T="03">e.g.,</E>
                         in presenting the results of its risk assessment, the EPA concludes that maleic anhydride, chlorine, acrylic acid, and acrylonitrile present the highest acute inhalation risks for the SOCMI source category) even though the EPA claims a second residual risk review is only warranted for chloroprene and EtO because of the IRIS reassessments. The commenter claimed that the EPA's approach is arbitrary and unfounded because the Agency asserts no basis for conducting a new risk review for any pollutants other than chloroprene and EtO.

                         As explained above in response to another comment in this section of this preamble, new information about risks of chloroprene and EtO exposure has come to light, warranting an updated residual risk review for the SOCMI and Neoprene Production (within the P&amp;R I NESHAP) source categories. This risk review was conducted in accordance with longstanding, congressionally and judicially approved steps laid out in the 1989 Benzene NESHAP. Those steps account for the risk due to emissions of all HAP from a source category and the risk review is not limited to one or two HAP solely because updated risk information is available for only two HAP. Therefore, in order to make risk acceptability and ample margin of safety determinations for each source category, we assessed risks for all HAP emitted by the SOCMI and Neoprene Production source categories.
                    </P>
                    <P>Importantly, though, the EPA is only imposing new standards under CAA section 112(f)(2) to control EtO and chloroprene emissions. The EPA is not imposing CAA section 112(f)(2) standards to control maleic anhydride, chlorine, acrylic acid, or acrylonitrile in this rulemaking and we found no new information regarding the health effects associated with these pollutants (like the new information on chloroprene and EtO) that would lead us to amend standards for these pollutants under CAA section 112(f)(2). Commenters do not provide any explanation, therefore, of how they are affected or harmed by the EPA analyzing other HAP during this risk review. We have concluded that unacceptable risk posed by emissions from these source categories is driven by emissions of EtO and chloroprene and we imposed additional standards under CAA section 112(f)(2) to reduce emissions of EtO and chloroprene to an acceptable level.</P>

                         A commenter argued that given the EPA's failure to articulate a legal basis for its position to conduct a second risk review violates the Agency's obligation to set forth in a proposed rule “the major legal interpretations and policy considerations underlying the proposed rule” according to CAA section 307(d)(3)(c), the commenter did not have adequate notice or an opportunity to comment on this key issue, which plainly is of central relevance to the rule. The commenter asserted that the EPA must supplement the current proposal to provide the required legal analysis and provide a reasonable opportunity for public comment.

                         The EPA explained in the proposed rule that we were undertaking an updated residual risk review for the SOCMI and Neoprene Production (within the P&amp;R I NESHAP) source categories “due to the development of the EPA's Integrated Risk Information System (IRIS) inhalation unit risk estimate (URE) for chloroprene in 2010” and because “in 2016, the EPA updated the IRIS inhalation URE for EtO.” 88 FR at 25083-84.
                    </P>
                    <P>The EPA explained that, due to the updated chloroprene information, “the EPA conducted a CAA section 112(f) risk review for the SOCMI source category and Neoprene Production source category. In the first step of the CAA section 112(f)(2) determination of risk acceptability for this rulemaking, the use of the 2010 chloroprene risk value resulted in the EPA identifying unacceptable residual cancer risk caused by chloroprene emissions from affected sources producing neoprene subject to P&amp;R I[.] Consequently, the proposed amendments to P&amp;R I address the EPA review of additional control technologies, beyond those analyzed in the technology review conducted for P&amp;R I, for one affected source producing neoprene and contributing to unacceptable risk.” 88 FR at 25083-84.</P>
                    <P>Similarly, the EPA explained that, due to updated EtO information, “In the first step of the CAA section 112(f)(2) determination of risk acceptability for this rulemaking, the use of the updated 2016 EtO risk value resulted in the EPA identifying unacceptable residual cancer risk driven by EtO emissions from HON processes. Consequently, the proposed amendments to the HON also address the EPA review of additional control technologies, beyond those analyzed in the technology review conducted for the HON, focusing on emissions sources emitting EtO that contribute to unacceptable risk.” 88 FR at 25084.</P>
                    <P>
                        The EPA also explained that “even though we do not have a mandatory duty to conduct repeated residual risk reviews under CAA section 112(f)(2), we have the authority to revisit any rulemaking if there is sufficient evidence that changes within the affected industry or significant new scientific information suggesting the public is exposed to significant increases in risk as compared to the previous risk assessments prepared for earlier rulemakings.” 88 FR at 25090.

                         88 FR at 25111 (“Considering all of the health risk information and factors discussed above, particularly the high MIR for both the SOCMI and Neoprene Production source categories, the EPA proposes that the risks for both source categories are unacceptable. . . . [W]hen risks are unacceptable, under the 1989 Benzene NESHAP approach and CAA section 112(f)(2)(A), the EPA must first determine the emissions standards necessary to reduce risk to an acceptable level, and then determine whether further HAP emissions reductions are necessary to provide an ample margin of safety to protect public health or to prevent, taking into consideration costs, energy, safety, and other relevant factors, an adverse environmental effect.”).

                        The EPA clearly did articulate its legal position in a manner that was sufficient to provide the public a meaningful opportunity to comment on the basis for its action, as evidenced by the EPA's receipt of comments from several commenters discussing the EPA's use of its CAA section 112(f)(2) authority to conduct an updated residual risk review and discussing the merits of the risk review. As explained in this section, commenters argued on both sides: that the EPA did not have authority to conduct the risk review in this rule, or that the EPA must conduct additional risk reviews during every 112(d)(6) technology review. (See other responses above in this section of this preamble.) While comments may not provide the only evidence that a point was adequately noticed, “insightful comments may be reflective of notice and may be adduced as evidence of its adequacy.”

                         A commenter said that they supported the EPA's proposed definition for “in ethylene oxide service” for process vents and the sampling and analysis procedures for owners and operators to demonstrate that each process vent does, or does not, meet the definition. However, other commenters requested the following clarifications or revisions to the proposed text:
                    </P>
                    <P>• the EPA should revise the definition of “in ethylene oxide service” and the corresponding procedures in 40 CFR 63.109(a) for determining whether a process vent is in EtO service so that the corresponding 1 ppmv cut-off for process vents in the definition of “in ethylene oxide service” applies on an annual average basis. The commenter provided numerous examples showing that EtO concentration in the process or the vent stream can vary over time depending on what material is being produced.</P>
                    <P>• the EPA should clarify that the 5 lb/yr EtO mass emission rate limit for combined process vents as specified in 40 CFR 63.113(j)(2), 40 CFR 63.124(a)(4) and (a)(4)(iii), and within the definition of “in ethylene oxide service” should be on a CMPU-by-CMPU basis.</P>
                    <P>
                        • the EPA should clarify at 40 CFR 63.109(a) that the location to measure the EtO concentration for process vents should be after the last recovery device (if any recovery devices are present) but prior to the inlet of any control device that is present and prior to release to the atmosphere to be consistent with requirements elsewhere in the HON (

                    </P>
                    <P>Commenters requested that the EPA revise the concentration threshold for process vents from 1 ppmv to 3 ppmv or greater and only require additional control of process vents that total 100 pounds per year or more on an affected source basis. The commenters argued these thresholds would alleviate detection limit challenges; and that process vents with concentrations and mass emissions rates below these thresholds do not significantly contribute to unacceptable risk. A commenter pointed out that moisture and interferents will prevent obtaining measurements down to 1 ppmv in certain streams such as those associated with vacuum distillation operations where motive force is provided by steam jet exhaust, and the emission point contains primarily steam with potentially trace levels of organic HAP, or in streams at the inlet to control devices.</P>

                         We acknowledge a commenter's support of the definition for “in ethylene oxide service” for process vents and the procedures for owners and operators to demonstrate that process vent does, or does not, meet the definition. However, we are not revising the definition in the final rule as requested by other commenters such that it applies on an annual average basis. We also disagree with the commenters' request to revise the concentration threshold for process vents from 1 ppmv to 3 ppmv or greater and only require additional control of process vents that total 100 pounds per year or more on an affected source basis.
                    </P>
                    <P>While we agree that the EtO concentration in the process or the vent stream can vary over time depending on what material is being produced, we consider the corresponding 1 ppmv EtO cut-off for process vents reasonable in terms of being measurable and quantifiable, and also appropriate for the vent stream characteristics we intended to regulate that resulted in risk reductions. We acknowledge every facility is different. Some facilities may pose less risks than others, but in a densely populated area with a nearby receptor and under specific conditions, the risks could none-the-less be unacceptable. In order to be protective of public health, we took a conservative approach.</P>
                    <P>We note that several facilities reported (in response to our CAA section 114 request) EtO measurements below 1 ppm; one of these measurements is equivalent to greater than 0.5 lb/hr and all other measurements below 1 ppm exhibited mass rates less (sometimes much less) than 0.02 lb/hr. Given that there do not appear to be detection limit challenges based on this recent stack test data, we disagree with the commenters' assertion that there is a need to alleviate detection limit challenges. Additionally, the 1 ppmv undiluted EtO threshold is also used in the Miscellaneous Organic Chemical Manufacturing NESHAP (MON) and we are not aware of any detection limit issues within that source category.</P>
                    <P>
                        With regard to a commenter's request that the 5 lb/yr EtO mass threshold for combined process vents be on a CMPU-by-CMPU basis, we agree that this was our intent; therefore, we have clarified this in the final rule at 40 CFR 63.113(j)(2), 40 CFR 63.124(a)(4) and (a)(4)(iii), and within the definition of “in ethylene oxide service.” Finally, as requested by a commenter, we have clarified at 40 CFR 63.109(a)(3) that the

                         Commenters said that they supported the EPA's proposed definition for “in ethylene oxide service” for storage vessels and the sampling and analysis procedures for owners and operators to demonstrate that each storage vessel does, or does not, meet the definition.

                    </P>
                    <P>• the EPA should revise the definition of “in ethylene oxide service” so that the corresponding the 0.1 percent by weight threshold for storage vessels in the definition of “in ethylene oxide service” applies on an annual average basis. The commenter pointed out that this is already allowed for equipment leaks at 40 CFR 63.109(c)(1); therefore, the EPA could amend the language in 40 CFR 63.109(b) to consistent with 40 CFR 63.109(c).</P>
                    <P>• the EPA should add more flexibility to the alternative approach in 40 CFR 63.109(b)(2) to allow for good engineering judgment and process knowledge similar to the language in 40 CFR 63.109(c)(2) for equipment leaks.</P>
                    <P>• the EPA should revise the definition to refer to “the procedures specified in § 63.109” instead of “sampling and analysis” to reduce confusion and eliminate the potential safety risks/costs of unnecessary sampling; it is not until proposed 40 CFR 63.109(b)(2) that the reader is informed that one is allowed to use information specific to the stored fluid to calculate the concentration of E.O., which does not necessitate sampling.</P>
                    <P>
                        A commenter also pointed out that the EPA's proposed definition does not comport with the definition discussed in the Agency's memorandum which states: “For storage vessels of any capacity and vapor pressure, “in ethylene oxide service” means that the concentration of ethylene oxide within the tank liquid is greater than or equal to 1 ppmw. These definitions exclude ethylene oxide that is present as an impurity . . .” (see Docket Item No. EPA-HQ-OAR-2022-0730-0074). The commenter requested that the EPA confirm the threshold for storage vessels is 0.1 percent by weight, as stated in the red-line strike-out version of the proposed rule text, and that the proposed definition should not include the phrase: “The exemption for “vessels storing organic liquids that contain organic hazardous air pollutants only as impurities” listed in the definition of “storage vessel” in this section does not apply for storage vessels that may be in ethylene oxide service.” Commenters added that the EPA should properly justify the 0.1 percent by weight threshold, or revise the threshold to eliminate unnecessary additional control of sources that do not pose unacceptable risk. The commenters asserted that the risks attributable to storage vessels are those storing high concentrations of EtO, not vessels storing low concentration materials, making the EPA's proposed 0.1 percent by weight threshold arbitrary. To address the unnecessary burden imposed by the EPA's proposal, the commenters requested the EPA revise its analysis such that only those storage vessels that significantly contribute to risk (
                        <E T="03">i.e.,</E>
                         those storing 100 percent EtO) be subject to additional control requirements for EtO.

                         The EPA acknowledges a commenter's support of the definition for “in ethylene oxide service” for storage vessels and the procedures for owners and operators to demonstrate that each storage vessel does, or does not, meet the definition. However, we are not revising the definition in the final rule as requested by other commenters such that it applies on an annual average basis; these commenters did not provide justification for why this revision is needed. We are finalizing the definition as proposed such that a storage vessel is considered in EtO service anytime it is storing a liquid that is at least 0.1 percent by weight of (or 1,000 ppmw) EtO. We consider the 0.1 percent by weight of EtO threshold reasonable in terms of being measurable and quantifiable, and also appropriate for the vent stream characteristics we intended to regulate that resulted in risk reductions. We acknowledge every facility is different. Some facilities may pose less risks than others, but in a densely populated area with a nearby receptor and under specific conditions, the risks could none-the-less be unacceptable. In order to be protective of public health, we took a conservative approach. We note that a 1,000 ppmw threshold corresponds to the chemical inventory reporting requirements under the Emergency Planning and Community Right-to-Know Act and other supplier notification requirements, so facilities should have knowledge of the amount of EtO stored from these sources.

                    <P>
                        Regarding the inconsistency between language used in docket item EPA-HQ-OAR-2022-0730-0074 versus language used in the red-line strike-out version of the proposed rule text, we have determined that the language used in docket item EPA-HQ-OAR-2022-0730-0074 is an error. In other words, we are finalizing the red-line strike-out version of the proposed rule text such that the definition does include the phrase: “The exemption for “vessels storing organic liquids that contain organic hazardous air pollutants only as impurities” listed in the definition of “storage vessel” in this section does not apply for storage vessels that may be in ethylene oxide service.” While we believe that emissions from vessels storing impurity levels of EtO are very low and do not result in additional risk, we are not providing additional constraints or clarifications on the determination of the threshold (
                        <E T="03">e.g.,</E>
                         providing averaging times) because we anticipate that the Emergency Planning and Community Right-to-Know Act and supplier notifications will generally be the basis for applicability determinations.
                    </P>
                    <P>Also, we disagree with the commenters' request to add more flexibility to the alternative approach in 40 CFR 63.109(b)(2) for storage vessels to be consistent with the equipment leaks provision at 40 CFR 63.109(c). We believe the rule is already clear regarding determining whether storage vessels are “in ethylene oxide service.” In order to determine the requirements for storage vessels in EtO service, facilities must look at both the definition of “in ethylene oxide service” and the requirements in 40 CFR 63.109 together. The definition of “in ethylene oxide service” lets the owner or operator designate a storage vessel based on process knowledge; however, if an owner or operator wants to say a storage vessel is not in EtO service, they must use the procedures in 40 CFR 63.109(b). The rule at 40 CFR 63.109(b)(2) already explicitly allows an avenue for an owner or operator to calculate the concentration of EtO of the fluid stored in the storage vessels if information specific to the fluid stored is available which includes data based on safety data sheets.</P>
                    <P>With regard to a commenter's request to change the phrasing of “sampling and analysis is performed as specified in § 63.109” to “the procedures specified in § 63.109 are performed” within the definition of “in ethylene oxide service” for storage vessels, we agree this suggested language is more clear and have revised it in the final rule.</P>

                         A commenter said they support the EPA's proposed rule text at 40 CFR 63.113(j) that requires owners and operators to reduce emissions of EtO from process vents in EtO service by either: (1) Venting emissions through a closed-vent system to a control device that reduces EtO by greater than or

The commenter also said they support the EPA's proposed rule text at 40 CFR 63.119(a)(5) that requires owners and operators to reduce emissions of EtO from storage vessels in EtO service by either: (1) Venting emissions through a closed-vent system to a control device that reduces EtO by greater than or equal to 99.9 percent by weight or to a concentration less than 1 ppmv for each storage vessel vent; or (2) venting emissions through a closed-vent system to a flare meeting the proposed operating and monitoring requirements for flares in NESHAP subpart F.
                    </P>
                    <P>However, other commenters argued that the EPA should disallow the use of flares to control EtO from process vents and storage vessels given that flares can only reduce EtO emissions by, at most, 98.6 percent; and therefore, cannot meet the proposed 99.9 percent by weight EtO reduction requirement. The commenters contended that the EPA arbitrarily and unlawfully assumes HON sources will use non-flare control devices instead of flares to reduce EtO from process vents and storage vessels. The commenters added that the Agency's supposition that it is “likely” that sources will not use flares given the flare cap provides no rational or substantial basis for assuming 99.9 percent destruction of EtO from process vents and storage vessels. A commenter contended that the difference between using a flare and a non-flare control device to reduce emissions of EtO from process vents and storage vessels could be significant, and provided an example using an emissions inventory from 2021 for Indorama's Port Neches plant showing this. A commenter asserted that requiring HON sources to use non-flare controls (and disallowing the use of flares) to control EtO from process vents and storage vessels would not result in additional costs beyond those that the EPA has already predicted, since the EPA's cost-effectiveness analysis assumed that all 12 HON facilities that need to control EtO from process vents and storage vessels to reduce risk to acceptable levels would install thermal oxidizers.</P>
                    <P>
                        The commenters added that unlike the HON, the EPA in its risk proposal for Neoprene Production processes subject to the P&amp;R I NESHAP (appropriately) proposes to require use of non-flare controls that reduce chloroprene by 99.9 percent. The commenters asserted that if the EPA were to finalize its proposal to allow HON sources to use flares to reduce EtO from process vents and storage vessels (and thus allow destruction efficiencies lower than 99.9 percent), this differing treatment of risk-driving HAPs from HON and P&amp;R I vents and storage vessels would render the Agency's final rule arbitrary and capricious.

We also disagree with other commenters' assertions that the EPA must prohibit the use of flares to control EtO from process vents and storage vessels. In the proposed rule, we recognized flares cannot achieve 99.9 percent EtO reduction and proposed an EtO flare load limit. We also noted that as part of the CAA section 114 request, six facilities measured EtO emissions from their EtO emission points and none of these six facilities currently use a flare to control EtO emissions from process vents or storage vessels. Even so, our modeling file does include several other HON facilities that do use flares to control process vents and storage vessels that emit EtO. Therefore, we accounted for these flares operating at 98 percent EtO reduction in our risk assessment, proposed an EtO flare load limit, and determined that it is not necessary for flares to achieve 99.9 percent EtO reduction in order to reduce risk to an acceptable level and provide an ample margin of safety to protect public health (provided that owners and operators still comply with the entire suite of EtO control requirements that we are finalizing in the rule). However, in response to a comment addressed in section IV.A.3.d.v of this preamble we are not including an EtO flare load limit in the final rule; and we determined that risks are acceptable for flares operating at 98 percent EtO reduction and flares operating at 98 percent EtO reduction provide an ample margin of safety to protect public health, without the need for an EtO flare load limit.

                         A commenter said that they supported the EPA's proposed definition for “in ethylene oxide service” for equipment leaks and the sampling and analysis procedures for owners and operators to demonstrate that process equipment does, or does not, meet the definition. However, some commenters requested the EPA revise the 0.1 percent by weight threshold to 5.0 percent by weight.

                    <P>
                        A commenter argued that most of EtO emissions from equipment leaks come from piping that has an EtO concentration of 5.0 percent by weight or higher. The commenter contended that expanding the new regulatory provisions to streams containing EtO between 0.1 and 5.0 percent by weight will result in a much more stringent LDAR program for components that are primarily in ethylene, methane, nitrogen, and carbon dioxide (CO
                        <E T="52">2</E>
                        ) service, and will have a minimal to negligible impact on reducing the fugitive emissions of EtO and the resulting residual risk. The commenter also recommended that the EPA revise 40 CFR 63.109(c)(1) and (2) to reflect the 5.0 percent by weight threshold instead of the 0.1 percent by weight threshold.

                        Other commenters asserted that the EPA does not explain why a 0.1 percent by weight threshold of EtO in equipment presents unacceptable risk; the commenters said based on their revised risk modeling assessment (including their recommended revisions to the HEM4 modeling file inputs such as revised flare parameterization, updates provided by companies, and removal of one time/infrequent release events), equipment containing less than 5 percent EtO does not significantly contribute to risk, nor is it cost-effective when considered in the context of an ample margin of safety analysis.

                         The EPA acknowledges a commenter's support of the definition for “in ethylene oxide service” for equipment leaks and the procedures for owners and operators to demonstrate that process equipment does, or does not, meet the definition. However, we reject other commenters' requests to revise the 0.1 percent by weight threshold to 5.0 percent by weight. As discussed in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023), results from our risk assessment indicate that, for the source category MIR of 2,000-in-1 million, approximately 20 percent is from emissions of EtO related to HON equipment leaks. We also note that the risk from EtO from HON equipment leaks at seven facilities (including the facility driving the MIR) is ≥100-in-1 million. To help reduce the risk from the SOCMI source category to an acceptable level, for EtO emissions from HON equipment leaks, we performed a review of available measures for reducing EtO emissions from components that are most likely to be in EtO service, which include connectors (in gas and vapor service or light liquid service), pumps (in light liquid service), and valves (in gas or light liquid service). Almost all EtO emissions related to equipment leaks come from these three pieces of equipment.
                    </P>
                    <P>We considered the proposed 0.1 percent by weight threshold reasonable in terms of being measurable and quantifiable, and also appropriate for the vent stream characteristics we intended to regulate that resulted in risk reductions. We acknowledge every facility is different. Some facilities may pose less risks than others, but in a densely populated area with a nearby receptor and under specific conditions, the risks could none-the-less be unacceptable. In order to be protective of public health, we took a conservative approach. Regarding comments that there is no justification for adding additional controls for low risk sources given the cost, in codifying the Benzene NESHAP approach CAA section 112(f)(2) does not allow us to consider cost at the first step of the residual risk analysis in identifying what standards are needed to reduce unacceptable risk to an acceptable level, and at proposal, and in the final rule, we determined that prior to application of the control requirements being finalized, the risk was unacceptable. It is only if the EPA adopts more stringent standards to further reduce emissions and reduce risks below acceptable levels if needed to provide an ample margin of safety to protect public health, at the second step of the residual risk analysis, that costs may be considered among other relevant factors.</P>
                    <P>With regard to a commenter's request to change the phrasing of “sampling and analysis is performed as specified in § 63.109” to “the procedures specified in § 63.109 are performed” within the definition of “in ethylene oxide service” for equipment leaks, we agree this suggested language is more clear and have revised it in the final rule.</P>

                        <E T="03">Comment:</E>
                         Several commenters objected to the EPA's proposal at 40 CFR 63.171(f) that does not allow delay of repair for equipment in EtO service.
                    </P>
                    <P>Commenters contended that the EPA did not consider the cost associated with more frequent and/or longer outage times due to removal of the delay of repair option. Commenters stated that most valves and connectors are not configured with in-line spares; and if a repair requires replacement of a leaking component, the equipment must be isolated, and in certain instances the entire process unit must be shutdown. Commenters contended that additional shutdowns directly increase the likelihood of future leaks given that each shutdown and startup cycle subjects equipment to pressure and temperature changes that could negatively impact equipment reliability.</P>
                    <P>Commenters added that, often, valves or other connectors may not be “off the shelf” so that a facility would be required to special order and wait on the equipment to arrive while shutdown. A commenter stated that lead up times to shutdowns typically provide adequate time for facilities to order and test components; however, if the delay of repair provisions are eliminated, required lead times for these activities will result in extended shutdowns. The commenter also said that facilities must often carefully evaluate the safety considerations of “boxing in” leaking EtO equipment due to the tendency of stagnant EtO to polymerize which can render equipment such as control valves inoperable. The commenter continued that it is often necessary to evaluate and engineer a clamp style solution, a process that can take more than the allotted 15-day repair time.</P>
                    <P>Commenters also noted additional consequences of more frequent shutdowns including additional wear on rotating equipment, and reduced catalyst life which could result in emission increases and waste generation.</P>
                    <P>A commenter argued that eliminating delay of repair would generally require a first repair attempt within 5 days of detection, which is an infeasibly short amount of time to safely shutdown one process unit, much less multiple integrated units. The commenter stated that delay of repair provides facilities with time needed to plan and prepare for a shutdown, which minimizes the safety risks that inevitably accompany shutdowns and startups. The commenter added that being required to shutdown abruptly and more frequently will unnecessarily increase safety risks to employees with minimal environmental benefit. The commenter said that they follow standard industry procedures in preparing for a scheduled shutdown, which involves adequate preparation time and personnel to completely purge of all lines containing EtO, using appropriate controls, before shutdown. The commenter said that stagnant EtO polymerizes, creating heat that can cause explosions.</P>
                    <P>
                        Commenters argued that an increase in number of shutdowns due to the EPA eliminating delay of repair for equipment in EtO service could also result in impact to supply chain. A commenter said that supply chain disruptions pose significant economic, security and health risks. Another commenter added that impacts on supply could well impact broader EPA and Administration priorities such as the EPA's recent proposal to electrify motor vehicles which is dependent upon EV battery production (and such battery production is currently generally dependent upon ethylene carbonate, which is produced by reacting EtO with CO
                        <E T="52">2</E>

                    <P>
                        Commenters contended that the EPA failed to explain how eliminating delay of repair for equipment in EtO service would reduce EtO emissions or risks. Commenters argued that eliminating the delay of repair provisions results in an increase in emissions due to more frequent shutdowns. Commenters contended that without the ability to delay repair, it will result in unplanned shutdowns which will result in greater emissions as emissions are expected to be higher during shutdown than emissions from components on delay of repair. A commenter said EtO emissions can range from approximately 5 to 340 lbs per shutdown event and provided calculations showing that a repair of a 
                        <PRTPAGE P="42976"/>
                        leaking valve would have to be delayed for over 10 years before the emissions exceeded those generated by a CMPU shutdown that resulted in 85 lbs of EtO emissions. Some commenters pointed out that delay of repair provisions allow facilities to assess whether allowing a small leak to continue poses less risk and concern than the emissions necessarily associated with a shutdown.
                    </P>
                    <P>A commenter argued that they would expect only a small number of component(s) in EtO service to use the delay of repair provisions at 40 CFR 63.171 given that HON CMPUs that produce and use EtO as a raw material will typically have a planned process shutdown every 2 to 3 years depending on the specific process.</P>
                    <P>Another commenter suggested that the EPA adopt the TCEQ delay of repair program as described in 30 Texas Administrative Code (TAC) 115.352(2): If the repair of a component within 15 days after the leak is detected would require a process unit shutdown that would create more emissions than the repair would eliminate, the repair may be delayed until the next scheduled process unit shutdown. The commenter argued that the TCEQ requirement is reasonable given that it allows companies to choose the lowest-emitting option and attain the goal of minimizing emissions.</P>

                         Regarding commenters' assertions about cost and timing of repair, with one exception, we are finalizing the proposed requirements for delay of repair for equipment in EtO service pursuant to CAA section 112(f)(2), on the basis of risks being unacceptable. Where we find risks are unacceptable, the EPA must determine the emissions standards necessary to reduce risk to an acceptable level. The largest contributor to risk from EtO facilities is due to emissions from equipment leaks. Because emissions of EtO from the SOCMI source category result in unacceptable risks, we proposed and are finalizing requirements that would reduce risks to an acceptable level, including provisions not allowing a delay of repair for equipment in EtO service. Allowing delay of repair would allow increased emissions of EtO and increased risk. The one exception is that we are revising 40 CFR 63.171(b) to allow a delay of repair for equipment if the equipment is isolated from the process and does not remain in organic HAP service.
                    </P>
                    <P>
                        To the commenters' assertions that increased startup and shutdown events will lead to additional EtO emissions, we disagree. First, we have removed the exemptions for periods of SSM. As a result, facilities must be in compliance with the rule requirements at all times and must control EtO emissions at all times. Therefore, while there may be additional EtO entering the control device as a result of SSM, the finalized control provisions ensure risk remains acceptable. Second, we are finalizing maintenance vent requirements which are intended to address equipment openings that result from startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. We are finalizing that owners and operators may not release more than 1.0 ton of EtO from all maintenance vents combined per any consecutive 12-month period. An owner or operator may designate any process vent as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. Thus, shutdowns resulting from the identification of leaks could be included under the 1.0 tpy EtO limit. It is the responsibility of the owner or operator to plan accordingly for equipment replacement and minimizing safety risks during shutdowns. Third, using the commenters' estimates of EtO emissions ranging from 5 to 340 lbs per shutdown event, the number of shutdowns that could fall under the 1 tpy limit could range from almost 6 to 400. Given the typical leak rates seen by industry (as discussed in our responses to comments in section 2.2 of the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         which is available in the docket for this rulemaking) and the variety of process conditions, the EPA believes that it would be unlikely for a facility to develop 5 leaks at the maximum estimated EtO levels warranting shutdown events. We note that even if a facility were to reach the 1.0 tpy maintenance vent limit, they may still shutdown to repair leaking equipment so long as the emissions are controlled.

                         In response to the EPA soliciting comments on alternative monitoring technologies, a commenter supported optical gas imaging (OGI) be used as an option to find larger equipment leak air emissions and to repair leaks, and that perhaps it could be used in conjunction with an annual connector monitoring program for connectors in EtO service. Another commenter contended that the EPA failed to include LDAR alternatives for use of OGI despite the agency's recognition of its efficacy in the recent NSPS subpart OOOOb and EG subpart OOOOc proposed rules and development of Appendix K, which specifically states it is the methodology that the EPA plans to incorporate by reference in the different NSPS/NESHAP subparts to enable implementation of this technology. The commenter contended that the EPA should correct this inconsistency. A commenter recommended that if the EPA determines OGI is an appropriate option to include in the final rule, the EPA model the specific OGI requirements after those contained in NSPS subpart OOOOa at 40 CFR 60.5397a(c)(7) and (d)(1) that address fugitive emissions monitoring plans where OGI is used and the requirements in 40 CFR 60.5397a(h)(4)(iv) that address resurveying equipment to verify repair. The commenter noted that some of the requirements in NSPS subpart OOOOa relative to OGI monitoring will need to be adjusted to account for application of OGI to a CMPU and not an oil and gas production site, as there are more potential interferences in a CMPU.
                    </P>
                    <P>Another commenter contended that the EPA has not clearly addressed the use of any alternative work practices for fugitive monitoring such as OGI but is soliciting technical justification to include or exclude OGI as an option for the proposed low (100 ppmv) detection levels using EPA Method 21. The commenter added that this low concentration has not been evaluated as a level which can be observed reliably and consistently with an OGI camera. The commenter requested that any technical evaluation and proposed outcome be re-published as a proposal to ensure comprehensive evaluation by all potentially affected parties and authorities. The commenter concluded that the EPA should not collect comments, complete a review, and make a final rule change without further opportunity for comment.</P>

                        A commenter stated that based on publicized research, including the EPA's Optical Gas Imaging Appendix K Technical Support Document, there is a known variability of response factors within chemical plant gas streams and the detection/sensitivity ranges of OGI technology versus legacy technologies. The commenter noted that case-by-case permits have been issued with an OGI alternative; however, each of these 
                        <PRTPAGE P="42977"/>
                        permits has incorporated an annual EPA Method 21 survey to ensure that all components have been properly evaluated for leaks, and the commenter recommended adding this requirement for any OGI alternative for these sites.
                    </P>
                    <P>A commenter noted that the results obtained using OGI for leak detection can be heavily influenced by instrument performance, environmental conditions, and human factors. The commenter explained that weather conditions such as ambient temperature, wind speed, or wind direction relative to the observer may affect the apparent concentration of any leak when viewed with OGI. The commenter stated that a study of OGI for detection of natural gas leaks found that only 51 percent of leaks were detected at wind speeds above 21 miles per hour. The commenter opined that higher concentrations of gas streams may be needed for detection to occur with OGI technology, especially as it applies to OGI surveys within the chemical sector, whereas the annual EPA Method 21 survey ensures a quantitative measurement and more appropriately demonstrates compliance. The commenter requested the EPA clarify if it plans to include the proposed Appendix K or another monitoring protocol for OGI to be followed so that there are clear and consistent expectations of field experience for camera operators including operator training, component dwell time, required operator breaks, and other criteria which are not addressed in 40 CFR 63.11.</P>

                         We disagree with the commenters that stated the rules should have required the use of OGI. The SOCMI has been complying with equipment leak regulations since the early 1980s, and leaks are much smaller than those found in the oil and gas industry. As a result, the leak definitions that SOCMI facilities are complying with are in the area of 500 to 1000 ppm for most equipment, and the proposed and final rule lowers leak definitions to 100 ppm for valves and connectors in EtO service. We acknowledge that OGI is effective at finding large leaks quickly for many compounds. OGI is less effective at finding low-level leaks, especially in the environmental conditions that generally exist during a field survey. As a commenter indicated, the low leak concentrations that were proposed and which we are finalizing (100 ppm) have not been evaluated at a level which can be observed reliably and consistently with an OGI camera. In feasibility studies conducted as part of the development of 40 CFR part 60 appendix K,
                        <SU>42</SU>

                         which are the procedures for using OGI in leak detection, leaks below 500 ppm (or even higher in some circumstances) could not be reliably detected even in a laboratory setting except under the most ideal conditions. We also agree with the commenter who noted that leak detection with an OGI camera is heavily influenced by environmental conditions and human factors. Additionally, as explained more fully in response to a comment in section IV.B.3.b.ii of this preamble, OGI cameras, especially in the most common filter bandwidths, are not sensitive to some of the chemicals found at SOCMI facilities, which can make leaks difficult or even impossible to see, even for large leaks. In promulgating NSPS subpart OOOOb and EG subpart OOOOc, the EPA considered the level of control required for fugitive emissions in the oil and natural gas sector, as well as the chemical make-up of the expected fugitive emissions. Based on those considerations, we determined that OGI was a viable option for facilities subject to regulation under those subparts through our BSER analysis. However, for the reasons outlined in this response, while the use of OGI is appropriate for the oil and natural gas sector, it would not be appropriate to rely exclusively upon OGI for the SOCMI source category.

                         A commenter said that they supported the EPA's proposed definition for “in ethylene oxide service” for heat exchange systems and the sampling and analysis procedures for owners and operators to demonstrate that each heat exchange system does, or does not, meet the definition. However, commenters requested the following clarifications or revisions to the proposed text:
                    </P>
                    <P>• the EPA should add into the definition an exclusion for EtO present as an impurity consistent with the Agency's memorandum which states: “This definition excludes ethylene oxide that is present as an impurity.” (see Docket Item No. EPA-HQ-OAR-2022-0730-0074).</P>
                    <P>• the EPA should revise 40 CFR 63.109(e) to allow the ability to use good engineering judgment to determine the percent of EtO in the process fluid as they have for equipment leaks in 40 CFR 63.109(c)(2). The commenters said that process fluids serviced by heat exchange systems are the same process fluids contained in equipment that must be evaluated for “in ethylene oxide service,” and this prohibition negates the cost savings and flexibility allowed by the use of good engineering judgment for equipment leaks because facilities will be required to conduct sampling and analysis on the same process streams regardless under the heat exchange system provisions. The commenters added that sampling and analyzing process fluids subject to the monitoring requirements for heat exchange systems presents the same issues and difficulties that the EPA identified as the basis for allowing engineering judgment under the MON RTR.</P>
                    <P>
                        • the EPA should consider allowing facilities to account for site-specific conversion of EtO to ethylene glycol in water in heat exchange systems based on the characteristics (

                        Some commenters requested the revise the 0.1 percent by weight threshold to at least 0.5 percent by weight. These commenters argued that a heat exchanger with an industry-average flow rate with a leak rate of 3.6 ppmw and a process fluid concentration of 0.5 percent EtO would not pose unacceptable risk if the leak were to occur for 135 days as allowed by the existing heat exchange system monitoring provisions (

                         quarterly sampling plus a 45-day repair period). A commenter asserted that the EPA does not explain why a 0.1 percent by weight threshold of EtO in process fluid presents unacceptable risk.

                         We acknowledge the commenter's support of the definition for “in ethylene oxide service” for heat exchange systems and the procedures for owners and operators to demonstrate that each heat exchange system does, or does not, meet the definition. However, we disagree with other commenters' requests to revise the 0.1 percent by weight threshold to at least 0.5 percent by weight. We consider the 0.1 percent by weight threshold reasonable in terms of being measurable and quantifiable, and also appropriate for heat exchange system leak characteristics we intended to regulate that resulted in risk reductions. We acknowledge every facility is different. Some facilities may pose less risks than others, but in a densely populated area with a nearby receptor and under specific conditions, the risks could none-the-less be unacceptable. In order to be protective of public health, we took a conservative approach.
                    </P>
                    <P>
                        We agree to the commenter's request to allow the ability to use good engineering judgment at 40 CFR 63.109(e) to determine the percent of

                        EtO of the process fluid cooled by the heat exchange system similar to what we have allowed for equipment leaks in 40 CFR 63.109(c)(2). We are making this change in the final rule due to the difficulty and issues with sampling and testing fluid in process lines, particularly if the fluid contains EtO. Also, we believe the use of site-specific conversion calculations of EtO to ethylene glycol in heat exchange systems already qualifies as good engineering judgment using calculations based on process stoichiometry; however, due to its relation to risk as previously discussed, the threshold for determining if equipment is “in ethylene oxide service” is not being revised per the commenter's request.
                    </P>
                    <P>Regarding the language used in docket item EPA-HQ-OAR-2022-0730-0074 versus it not being included in the red-line strike-out version of the proposed rule text, we have determined that the language used in docket item EPA-HQ-OAR-2022-0730-0074 is an error. In other words, we are finalizing the red-line strike-out version of the proposed rule text and are not including an exclusion for EtO present as an impurity. The 0.1 percent by weight threshold already accounts for impurities.</P>

                        <E T="03">Comment:</E>
                         A commenter said they support the EPA's proposed rule text at 40 CFR 63.104(g)(6) and (h)(6) that requires owners and operators to conduct more frequent leak monitoring (weekly instead of quarterly) for heat exchange systems in EtO service and repair leaks within 15 days from the sampling date (in lieu of the current 45-day repair requirement after receiving results of monitoring indicating a leak in the HON), and delay of repair would not be allowed.
                    </P>
                    <P>However, other commenters raised the following concerns with regard to sampling frequency and delay of repair. Commenters recommended that the EPA modify the proposed 40 CFR 63.104(g)(6) to require monthly (in lieu of weekly) sampling via the Modified El Paso Method. A commenter contended that weekly monitoring of each heat exchange system will require either multiple sampling apparatuses or frequent movement of the sampling apparatus from one system to another. Similarly, another commenter argued that weekly sampling presents some logistical problems as typically a contractor brings in the monitoring device, which is a skid mounted unit; the contractor will then move the device from one sampling location to additional sampling locations at the site. In some cases, the commenter said that the monitoring skid must be moved to other process areas that are subject to the other rules such as the Ethylene MACT and the MON rule; therefore, a requirement to conduct this type of monitoring on a weekly basis will limit the flexibility to move the monitoring skid at the site.</P>
                    <P>The commenters suggested that the monthly Modified El Paso Method monitoring could be combined with weekly analysis of a surrogate parameter as an alternative to conducting weekly sampling using the Modified El Paso Method. The commenters said that the surrogate parameter could be something like monitoring weekly using a water analytical method to indicate the presence of a leak or monitoring other parameters that would indicate the presence of a leak; and if a surrogate measurement indicates a leak, the facility would be required to confirm the presence of the leak using the Modified El Paso Method and repair as required by the proposed provisions.</P>
                    <P>A commenter requested that the EPA not eliminate the option that allows facilities to delay the repair provided emissions from the process shutdown needed to repair the leak are greater than the potential emissions of delaying. The commenter said that this option essentially allows facilities to repair the leak with as little emissions and environmental impact as possible by requiring the facility to evaluate the emissions of a continued leak against the emissions from an entire process shutdown. The commenter claimed that allowing a repair to be delayed until the next process unit shutdown, if emissions from the delay would be less than those from the unplanned shutdown itself, has been a longstanding concept in several chemical sector rules (see for example 40 CFR 60.482-9(c), 63.104(e)(2)(i), 63.171(c), 63.1024(d)(3), and 63.105(d)(3)). The commenter contended that by forcing facilities to repair leaks solely based on a concentration-based threshold, facilities with a smaller recirculation rate will likely emit greater amounts of HAP than if they were allowed to assess the overall mass emissions from the leak versus shutdown and choose the option that minimizes emissions.</P>
                    <P>The commenter also said that it is unclear why the EPA is proposing to not allow facilities to delay a repair by isolating the equipment such that it is no longer in EtO service. The commenter said that in certain instances, a facility may be able to isolate a leaking heat exchanger but cannot open the equipment until a process unit shutdown.</P>
                    <P>
                        <E T="03">Response:</E>

                    <P>
                        However, we disagree with other commenters' request to require monthly (in lieu of weekly) sampling via the Modified El Paso Method. As we stated in the document titled 
                        <E T="03">Analysis of Control Options for Heat Exchange Systems to Reduce Residual Risk of Ethylene Oxide in the SOCMI Source Category for Processes Subject to HON</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0071), we determined baseline EtO emissions and emissions reductions using information the EPA received from Union Carbide Corporation-Seadrift, TX about an EtO emissions event (Incident 293911) that was reported to the TCEQ on October 21, 2018. Using information provided, we calculated different sampling and repair periods required to reduce risks to an acceptable level. Because at least a 90+ percent reduction in EtO emissions is needed to get to this level (as the risk posed by this large leak is at least 400-in-1-million based on current the HON standards and Union Carbide's best case emissions estimates and because other emission sources also contribute to risks), we determined that if the facility identifies and repairs an EtO leak (from a heat exchange system) within 15 days from a weekly sampling event, the facility would achieve a 6.06 tpy EtO emission reduction (
                        <E T="03">i.e.,</E>
                         93 percent reduction in EtO emissions). Less frequent sampling (
                        <E T="03">e.g.,</E>
                         monthly) and more time to repair the leak from the sampling period does not get to the level of reduction needed to bring facility risk to below 100-in-1 million. We also noted that the facility indicated they are currently conducting weekly sampling for leaks of EtO already and have implemented this type of sampling across all their facilities that have heat exchange systems cooling process streams with EtO.
                    </P>
                    <P>
                        In addition, we also reject the commenters' request to use a weekly analysis of a surrogate parameter as an alternative to conducting weekly sampling using the Modified El Paso Method. Surrogate methods via water analysis are less sensitive than the Modified El Paso Method. Therefore, though weekly monitoring via a 
                        <PRTPAGE P="42979"/>
                        surrogate would catch the largest of leaks, there would still be the potential for leaks to go uncaptured until the next monthly check via the Modified El Paso Method. As a result, to keep risk at an acceptable level, we maintain that weekly monitoring via the Modified El Paso Method is appropriate.
                    </P>
                    <P>
                        Similarly, we reject a commenter's request to allow delay of repair at 40 CFR 63.104(h)(6) for heat exchange systems in EtO service. As previously discussed, our leak analysis is based on reducing the delay of repair to achieve a cancer risk incidence at or below 100-in-1 million. Given that EtO is a major cancer driver, leaks need to be addressed quickly to keep risk at an acceptable level. Having said this, we agree with the commenter that owners and operators should be allowed to delay a repair by isolating the equipment (
                        <E T="03">e.g.,</E>
                         a heat exchanger) such that it is no longer in EtO service. It was our intent to allow this type of delay of repair which has always been allowed in the HON at 63.104(e). In this scenario, the owner and operator may delay repair indefinitely as there is no longer an active EtO leak once the equipment is isolated and not in EtO service. For this reason, we are revising 40 CFR 63.104(h)(6) in the final rule to include the following allowance: “Delay of repair of heat exchange systems in ethylene oxide service for which leaks have been detected is allowed if the equipment is isolated from the process such that it is no longer in ethylene oxide service.”

                         A commenter said that they supported the EPA's proposed definition for “in ethylene oxide service” for wastewater and the sampling and analysis procedures for owners and operators to demonstrate that each wastewater stream does, or does not, meet the definition. However, other commenters requested the EPA reevaluate the 1 ppmw EtO concentration threshold for wastewater control. These commenters contended that the EPA should make the EtO concentration threshold less stringent (
                        <E T="03">i.e.,</E>
                         a value &gt;1ppmw EtO) primarily on the basis that wastewater should not be regulated more strictly than process vents, there is negligible additional benefit for excessive complexity controlling down to 1 ppmw, and the majority of wastewater collection and treatment emissions will be captured even with a less stringent EtO concentration threshold for wastewater control. The commenters said the EPA does not state why a 1 ppmw threshold is necessary to reduce risks or provide an ample margin of safety, or why Group 1 streams should be classified based solely on this concentration threshold. The commenters recommended the EtO concentration threshold for wastewater control should be changed to an annual average concentration of either 25 or 27 ppmw EtO with an annual average flow rate of 10 liters per minute or higher (in lieu of proposing a no flow rate threshold).
                    </P>
                    <P>Additionally, commenters requested the EPA establish a mass threshold for wastewater as a “de minimis” value to prevent having to control very small or low flow intermittent wastewater streams that provide little risk reduction, and to raise the concentration commensurate with other rules. A commenter recommended the cutoff for each wastewater stream be a total annual average mass flow rate of EtO to the sewer of at least 0.01 lb/min (0.6 lb/hr). Other commenters requested the EPA add a cutoff such that none of a facility's process wastewater streams should be considered in EtO service if the entire collection of EtO-containing process wastewater streams from HON CMPUs contain no more than 0.24 tpy of EtO. Commenters pointed out that when reviewing the responses to the EPA's CAA section 114 request, typically only one existing Group 2 wastewater stream contributes the majority of the EtO baseload flow to the sewer system; and there are other process wastewater streams in which the EtO concentration is between 1 and 15 ppmw, and the flowrate of the stream is very low or very intermittent, resulting in flows to the sewer systems that are in some cases less than 0.1 lb/hr or even much lower. The commenters argued that it does not make sense to require Group 1 controls for these low volume streams as one is essentially treating almost pure water at this point.</P>

                        <E T="03">Response:</E>
                         The EPA acknowledges commenters' support and opposition to revise the Group 1 wastewater stream threshold to include wastewater streams in EtO service (
                        <E T="03">i.e.</E>
                         wastewater streams with total annual average concentration of EtO greater than or equal to 1 ppmw at any flowrate). We are finalizing the definition of “in ethylene oxide service” definition for wastewater as proposed. With regard to the commenters' assertion that the 1 ppmw threshold was not explained, the document titled 
                        <E T="03">Analysis of Control Options for Wastewater Streams to Reduce Residual Risk of Ethylene Oxide in the SOCMI Source Category for Processes Subject to HON</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0087) states that a 1 ppmw threshold is necessary to reduce risk of EtO emissions from wastewater, as the risk due to wastewater is as high as 200-in-1-million, which contributes to unacceptable risk. Additionally, the data from our CAA section 114 request shows that introducing a flowrate threshold, as one commenter suggested, would leave wastewater streams with large amounts of EtO uncontrolled, and could contribute to increased risk at some facilities over 100-in-1-million.
                    </P>
                    <P>Similarly, we disagree with the commenters' suggestion to include a mass threshold. We calculated the maximum amount of EtO emissions from wastewater streams that would push a facility over the 100-in-1-million mark, and found the lowest amount of excess EtO emissions to be 0.06 tpy. This is well under the commenters' suggestions for a mass threshold.</P>

                        <E T="03">Comment:</E>
                         A commenter said that they support the proposed provisions at 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii) to revise the Group 1 wastewater stream threshold to include wastewater streams in EtO service (
                        <E T="03">i.e.,</E>
                         wastewater streams with total annual average concentration of EtO greater than or equal to 1 ppmw at any flow rate). However, at least one commenter claimed that there is no need for the proposed provisions at 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii) because the current treatment options for process wastewater streams in EtO service are already adequate to meet the ample margin of safety provided the EPA made one edit to 40 CFR 63.138(e)(1) and (2) when controlling streams with lower concentrations of EtO than previously regulated by the EPA. The commenter recommended that the EPA add an option to both 40 CFR 63.138(e)(1) and (2) that allows the owner or operator to demonstrate compliance with the performance standard for EtO if the outlet concentration of EtO is less than 1 ppmw on an annual average basis. The commenter argued that based on the EPA's proposed definition of “in ethylene oxide service” for wastewater streams it may be difficult to demonstrate a 98- or 99-percent mass removal efficiency for EtO especially if the concentration flowing into the treatment device is a very low concentration; for example, if the inlet flow is 0.1 lb/hr then it may be difficult to demonstrate that the outlet flow is 0.002 lb/hr (98 percent efficiency) or 0.001 lb/hr (99 percent efficiency).
                    </P>
                    <P>The commenter argued that EtO should only be included on Table 9 to NESHAP subpart G and removed from Table 8 to NESHAP subpart G for the following reasons:</P>

                    <P>The commenter argued that the way the group determination procedures are structured, adding EtO to Table 8 (when it is already included as a Table 9 compound) is not going to change the fact that a stream containing more than 1 ppmw EtO is considered to be in EtO service and subject to further treatment and control regardless of whether the source is existing or new.</P>
                    <P>
                        <E T="03">Response:</E>
                         The EPA acknowledges the commenters' support for and opposition of the proposed wastewater provisions at 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii). We are finalizing these provisions as proposed. We believe the rule is clear with regard to demonstrating compliance with these provisions. A wastewater stream that is less than 1 ppmw EtO is not considered a Group 1 wastewater stream, since it would not meet the Group 1 criteria at 40 CFR 63.132(c)(1)(iii) and (d)(1)(ii), provided it does not meet the criteria at 40 CFR 63.132(c)(1)(i) and (ii), and (d)(1)(i) either.
                    </P>
                    <P>The EPA does not agree with the commenter that EtO should be removed from Table 8 to NESHAP subpart G. Simply put, the compounds in Table 8 do not biodegrade well and will need to be stripped, while the compounds in Table 9 to NESHAP subpart G can be treated using a biological treatment process. While we acknowledge EtO can be biodegraded (and is included in Table 9), its low Fe value (0.5) suggests that it can only be reduced by half when using a standard biological treatment method, and the remainder would need to be stripped out of the wastewater in order to meet the 1 ppmw threshold. Since we are building on the existing HON standards, we believe it is appropriate to restrict the treatment options given the risk associated with EtO, and have determined facilities will have to use steam stripping to comply with the proposed standards. For these reasons, it is not appropriate to add an option, as requested by the commenter, to both 40 CFR 63.138(e)(1) and (e)(2) that allows the owner or operator to demonstrate compliance with the performance standard for EtO if the outlet concentration of EtO is less than 1 ppmw on an annual average basis regardless of the control method.</P>
                    <P>However, we agree with the commenter that verifying mass reductions of 99 percent for wastewater streams containing small amounts of EtO may be difficult. As a result, we are providing language in the final rule at 40 CFR 63.138(b)(3) and (c)(3) that allows owners or operators to reduce, by removal or destruction, the concentration of EtO to less than 1 ppmw as determined by the procedures specified at 40 CFR 63.145(b). We believe these revisions add clarity that streams less than 1 ppmw EtO are no longer considered to be “in ethylene oxide service” per the definition and provides unity with the finalized addition of EtO to Table 8 to NESHAP subpart G.</P>

                         A commenter recommended that the EPA incorporate the test methods specified in 40 CFR 63.109(d) for analysis of EtO in wastewater directly into 40 CFR 63.144(b)(5)(i) to provide consistency and clarity with the regulation and to avoid the need to prepare additional sampling plans and method validation under 40 CFR 63.144(b)(5)(ii) and (iii). The commenter argued that in order to use the test methods specified in 40 CFR 63.109(d) for determining the annual average concentration of EtO in the wastewater streams (

                    <P>In addition, the commenter claimed that depending upon what treatment option is selected in 40 CFR 63.138 to meet the requirements for wastewater streams in EtO service, the test methods and procedures in 40 CFR 63.145(b) for determining compliance with concentration limit standards for non-combustion treatment processes in 40 CFR 63.138(b)(1) and (c)(1) cross-reference the methods specified in 40 CFR 63.144(b)(5)(i). The commenter asserted that by adding the methods specified in 40 CFR 63.109(d) for determining the EtO concentration to the list of acceptable test methods in 40 CFR 63.144(b)(5)(i), the EPA would be also fixing other cross-referencing issues in 40 CFR 63.145 at the same time.</P>

                         We are revising the final rule in response to the commenter's request to add the test methods specified in 40 CFR 63.109(d) for analysis of EtO in wastewater to 40 CFR 63.144(b)(5)(i). We agree that these test methods are relevant to calculate the annual average concentration of EtO needed to determine Group status, and, by including them, we should create consistency between 40 CFR 63.109(d), 40 CFR 63.144(b)(5)(i), and 40 CFR 63.145.

                         A commenter said that they support the proposed provisions at 40 CFR 63.104(k) to prohibit owners and operators from injecting wastewater into or disposing of water through any heat exchange system in a CMPU meeting the conditions of 40 CFR 63.100(b)(1) through (3) if the water contains any amount of EtO, has been in contact with any process stream containing EtO, or the water is considered wastewater as defined in 40 CFR 63.101. On the contrary, other commenters provided suggestions for this prohibition. At least one of these commenters contended that the EPA has not identified any risk associated with EtO-free wastewaters, nor has the EPA otherwise justified why EtO-free wastewaters are prohibited from injection. This commenter said they generally support not allowing 
                        <PRTPAGE P="42981"/>
                        waters containing EtO or chloroprene to be added to the cooling loop of a heat exchange system. However, the commenter noted that in the case of the HON and P&amp;R I rules, a wastewater is “water that is discarded” from a CMPU or an EPPU, respectively; therefore, wastewater that is injected into a cooling loop is not discarded water.
                    </P>
                    <P>Commenters argued the proposed language prohibiting the use of “wastewater” in heat exchange systems is a significant barrier to, if not total prohibition on, water reuse projects that are under consideration at various member facilities. The commenter requested that the EPA modify the prohibition on using “wastewater” in heat exchange systems to make clear that stormwater collected in process areas and treated wastewater from process areas that may include EtO but still qualify for discharge in accordance with a national pollutant discharge elimination system (NPDES) permit may be used in heat exchange systems.</P>
                    <P>A commenter said that the EPA should add the requirements into the process wastewater prohibition language that already exists in 40 CFR 63.132(f) (rather than include new provisions at 40 CFR 63.104(k)). The commenter claimed that the intent of the prohibition language in 40 CFR 63.132(f) is to prevent discarding a liquid or solid material containing greater than 10,000 ppmw of a Table 9 (to NESHAP subpart G) HAP to water or wastewater unless it is controlled as a Group 1 wastewater; and as currently proposed, a liquid or solid material that is in EtO service, could be discarded to a wastewater stream without control. The commenter urged the EPA to add the following sentence to the beginning of 40 CFR 63.132(f): “Owners or operators of each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(11), shall not discard liquid or solid stream containing EtO such that it is considered to be in EtO service, as defined in § 63.101 from a chemical manufacturing process unit to water or wastewater, unless the receiving stream is managed and treated as a Group 1 wastewater stream.” Alternatively, the commenter suggested the EPA could revise the proposed rule text in 40 CFR 63.104(k) in lieu of adding their request sentence to the beginning of 40 CFR 63.132(f).</P>

                         The EPA acknowledges the commenters' support for and opposition to the proposed provisions that prohibit the injection or disposal of wastewater containing or that has come in contact with EtO, through heat exchange systems. We are finalizing these provisions at 40 CFR 63.104(k) as proposed. We disagree with commenters' requests to allow stormwater or treated wastewater that may contain EtO but qualify for discharge under the NPDES. We note that in a 1980 document titled 
                        <E T="03">Water Quality Requirements of the Organic Chemicals Industry for Recycle/Reuse Applications,</E>
                         which is available in the docket for this rulemaking, the potential for increased recycle/reuse for process water in the EtO industry was evaluated. It was found that significant evaporation losses occur from process cooling towers. Any amount of EtO in wastewater sent to cooling towers will inevitably be stripped out and lead to a direct emission event. This is further expanded upon in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023), where we cite emissions events from two HON-subject facilities that reported EtO emissions from heat exchange systems. This was due to combining EtO entrained water with heat exchange water and not due to any heat exchange system leaks, and resulted in ~3 tpy of EtO total emitted. Given the current total risk associated with EtO, allowing any EtO in cooling towers would be unacceptable.

                         A commenter said that they support the proposed requirement at 40 CFR 63.108(p) that prohibits owners and operators from sending more than 20 tons of EtO to all of their flares combined in any consecutive 12-month period. Other commenters asserted that the EPA must strengthen the monitoring needed to ensure compliance with the EtO flare load limit proposed at 40 CFR 63.108(p). The commenters stated that the requirement that “the owner or operator must keep monthly records of the quantity in tons of ethylene oxide sent to each flare at the affected source and include a description of the method used to estimate this quantity” is left completely up to HON sources to determine how to calculate the amount of EtO sent to their flares. The commenters contended that this cannot ensure compliance with the EtO flare load limit, and thus, cannot ensure that risk is reduced to an acceptable level or that the standards provide an ample margin of safety to protect public health. The commenters asserted that this monitoring requirement is arbitrary and capricious and contrary to CAA sections 112(f) and 114(a)(3). The commenters suggested that the EPA require HON sources to calculate the amount of EtO sent to their flares by: (i) Continuously measuring the flow rate of the waste gas to the flare using a continuous emission monitoring system; (ii) continuously measuring the EtO concentration in the waste gas, also by a continuous emission monitoring system; and (iii) using the data from (i) and (ii) to calculate the actual EtO mass that is sent to the flare over a given time period. The commenters added that this calculation can be done every minute if needed or on an hourly average basis, to provide an accurate mass estimate of the flared EtO.

                    <P>Numerous other commenters opposed the EtO flare load limit for at least one or more of the following reasons:</P>

                        • the proposed cap would be problematic for more than just the flares that the EPA identified given that many owners and operators are currently applying a 99 percent EtO control efficiency to their existing flare operations.

                         TCEQ's control efficiency value for EtO (99 percent) combined with the EPA's determination that EtO emissions of 0.4 tpy would be acceptable (see Docket Item No. EPA-HQ-OAR-2022-0730-0070) would yield a 40 tpy (not 20 tpy) EtO flare load limit.

                    <P>• when conducting its dispersion modeling for EtO emissions from flares, the EPA did not use the modeling approach used by TCEQ which takes into account the heat release associated with combustion in a flare; TCEQ's modeling approach results in lower off-site impacts from flares, which calls into question whether a cap of flaring is necessary.</P>

                    <P>• the EPA's proposed solution to replace flares with thermal oxidizers is not practical from a timing or cost perspective.</P>
                    <P>• thermal oxidizers are generally not suitable destruction devices for PRD effluents; therefore, plants would need a new thermal oxidizer along with a flare operating for unplanned discharges like PRD vents, and the EPA's cost estimates are not reflective of the actual costs that would incur in the 2023-2026 timeframe to install a new thermal oxidizer system. It is common practice to size a thermal oxidizer for a normal range of VOC concentrations and normal flow and have an emergency flare to accommodate a higher concentration and flow from an event. Using a thermal oxidizer in lieu of a flare to manage EtO emissions would necessitate designing the oxidizer to accommodate these larger intermittent flows and higher inlet concentrations of VOC; however, such a design might not be feasible because normal operation might represent too much of a “turndown” from emergency operation.</P>
                    <P>• lead/delivery time for a new thermal oxidizer system could exceed 52 weeks, but 12 months is a best estimate.</P>
                    <P>• replacing flares with a thermal oxidizer essentially maintains greenhouse gas emissions at the same level since EtO is combusted in both applications.</P>
                    <P>• there may be safety and reliability considerations not addressed by the EPA with the use of a thermal oxidizer, which would require design and process safety features due to the reactive and flammable nature of EtO.</P>
                    <P>Commenters said that instead of replacing flares with thermal oxidizers to meet the EPA's proposed EtO flare load limit, owners and operators could potentially add a water scrubber between vent sources like storage vessels and railcar loading/unloading operations and the existing flares; however, this option would likely still need a larger EtO flare load limit than the 20 tpy limit the EPA has proposed. The commenters said that water from the scrubber could then be routed to the EtO manufacturing processes at these sites where the EtO could be recovered as a product stream. However, the commenters pointed out that during times when the EtO manufacturing process unit is not in service, the internal scrubber systems would need to be turned off as there is no viable location to recover the EtO out of the scrubber water stream. Thus, during times when storage vessels and railcar loading/unloading operations would need to occur but the production plant is not in service, the vent gas from the tank vents and loading/unloading operations would need to be routed to the existing logistics flares. In other words, the commenters contended that the amount of EtO that would be routed to these flares in the future is a function of the operating time of the production plant.</P>
                    <P>In summary, commenters said they are concerned that projects that would be needed in order to meet the 20 tpy EtO flare load limit could not be implemented within 2 years as proposed in 40 CFR 63.100(k)(11), nor would the EPA's proposed control option achieve the intended reductions and may actually result in an increase in secondary emissions. Thus, these commenters requested that the EPA either refrain from finalizing the proposed flare cap or increase the flare cap based on a 99 percent control efficiency and provide 3 years for facilities to comply with the revision.</P>

                         We are not finalizing the requirement at 40 CFR 63.108(p) that prohibits owners and operators from sending more than 20 tons of EtO to all of their flares combined in any consecutive 12-month period. In other words, we are not including an EtO flare load limit in the final rule. In response to a comment discussed in section 1.1 of the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         which is available in the docket for this rulemaking, we have determined that it is appropriate to use a different modeling approach for the final rule than the approach we used for the proposed rule (
                        <E T="03">i.e.,</E>
                         we used the TCEQ modeling guidelines to calculate effective flare stack parameters for the final rule in lieu of modeling all flare releases as standard point sources with temperatures less than 1,000 Kelvin and velocities less than one meter per second for the proposed rule). As explained in that response, modeling flare emissions using effective stack parameters accounts for heat release of the flare and better characterizes plume rise. After applying this approach for the final rule, we have determined the EtO flare load limit is no longer necessary as flares controlling EtO are no longer significant contributors to risk. Using the reported EtO emissions of 2.87 tpy (post-control) from the highest-emitting facility, we estimate that the facility's current combined total EtO load to flares is about 143.5 tpy (pre-control). Based on the revised modeling, a flare controlling 143.5 tpy (far higher than the proposed 20 tpy flare cap) is not a significant risk driver. Using the TCEQ modeling guidelines for flares, we have determined that risk for the SOCMI source category remains below 100-in-1 million without the need of an EtO flare load limit, but only after implementation of the standards we are finalizing for: (1) Process vents, (2) storage vessels, (3) equipment leaks, (4) heat exchange systems, and (5) wastewater “in ethylene oxide service,” as well as implementation of the final requirements to reduce EtO emissions from maintenance vents and PRDs. We note that by not finalizing an EtO flare load limit we also obviate the inconsistency we unintentionally created in the proposed rule by requiring owners and operators to comply with an EtO flare load limit while also requiring owners and operators to minimize emissions from PRDs by routing them to flares instead of venting to the atmosphere.

                         Commenters argued that the requirement at 40 CFR 63.165(e)(3)(v)(D) that considers any atmospheric release from a PRD in EtO service a violation will not reduce risk given that PRD releases are non-routine events that take place to prevent catastrophic equipment failure. The commenters contended that deeming atmospheric PRD releases a violation will not reduce their occurrence. The commenters stated that the proposed work practice standards at 40 CFR 63.165(e) (including the deviation determination criteria at 40 CFR 63.165(e)(3)(v)(A) through (C)) already provide an effective framework for addressing PRD releases.

                        The commenters added it is not cost-effective to route all PRDs to control devices; and the EPA wrongly assumes that all releases from PRDs in EtO service can and will be controlled as process vents as a result of the prohibition on such releases. The commenters provided numerous examples of why certain PRDs cannot be safely routed to a control device and/or would be technically infeasible in many process designs such as hydraulic limitations of flare systems or other controls, PRD backpressure, EtO incompatibility with other collected compounds, and polymerization of ethylene in closed vent systems. Commenters argued that because PRD releases are usually non-routine, infrequent, and episodic, piping and the control device would have to be sized 
                        <PRTPAGE P="42983"/>
                        to accommodate significantly larger flow than normal process vents, and the control device would be required to operate in an indefinite “stand-by” mode to accommodate unexpected and emergency releases. A commenter said “stand-by” mode may also require significant amounts of fuel and generate secondary combustion emissions on a continuous basis for a release that may or may not occur.

                         We are finalizing these requirements for PRDs in EtO service pursuant to CAA section 112(f)(2), on the basis of risks being unacceptable. Where we find risks are unacceptable, the EPA must determine the emissions standards necessary to reduce risk to an acceptable level. Because emissions of EtO from the SOCMI source category result in unacceptable risks, we proposed and are finalizing requirements that would reduce risks to an acceptable level, including provisions that would make all PRD releases of EtO directly to the atmosphere a violation of the standard. As explained in response to a comment in section 1.1 of the document titled

                         which is available in the docket for this rulemaking, the EPA modeled certain PRD releases of EtO during maintenance events which resulted in very high risk from one facility (

                         EtO risk from process vent emission sources emitted through PRDs is approximately 75 percent of the Port Neches facility's total SOCMI source category risk of 2000-in-1 million). There is no reason for not considering the impact of these events in our risk modeling and rulemaking. In response, we proposed and are finalizing a requirement that releases from PRDs in EtO service are a violation of the emission standard.

A commenter provided an example where under the proposed rule, both Huntsman Conroe and Huntsman Geismar facilities would be heavily burdened by the proposed HON EtO control requirements even though the EPA found that neither facility poses unacceptable risk.

                    <P>These commenters said that the EPA's proposed response to 8 facilities with EtO risk above the presumptive limit is a one-size-fits-all approach to addressing risk from the source category that unreasonably imposes stringent control requirements across all emissions sources at every facility, rather than addressing the residual risks that were actually identified. The commenters said the approach is inconsistent with CAA section 112(f) because half of the facilities affected by the proposed EtO standards do not present unacceptable risk to surrounding areas, yet the EPA proposes to impose emissions standards on these facilities that were derived without consideration of cost. A commenter pointed out that Congress explicitly granted the EPA the authority to consider variations among sources in promulgating emission standards under CAA section 112 through subcategorization; yet, the EPA has failed to utilize this statutorily available tool here. Commenters said that even if the Agency chooses not to subcategorize, the EPA has recognized that it is unreasonable to require controls on all facilities when a more targeted and less costly option may achieve an acceptable level of risk. The commenters pointed out that the EPA used a tailored approach in the RTR for sterilization facilities (see 88 FR 22790, 22826-28) and the proposed MON rule (see 84 FR 69182) which applied different levels of stringency in accordance with the different facilities' MIRs (in other words, the EPA tailored its acceptability analysis to address risk from the highest risk sources).</P>
                    <P>A commenter added that the EPA's approach is not sufficiently targeted because the applicability of the new EtO emissions standards would be governed by the definition of “in ethylene oxide service” that the EPA adopted in the MON, which was not derived with any consideration of the emissions characteristics of the SOCMI source category or the risk profile determined by the EPA's risk assessment of the SOCMI source category. The commenter contended that adopting the MON definition of “in ethylene oxide service” results in new EtO emissions standards that apply to approximately twice as many affected facilities as needed to address the risk that the EPA determines to be actionable.</P>

                         We disagree with the commenters that the EPA acted unreasonably in imposing controls across the entire SOCMI source category (note the commenter used the phrase “HON source category;” however, the source category covered by the HON is actually the SOCMI source category). We also disagree with the commenters that our action to impose the same EtO requirements on each owner and operator is arbitrary and capricious.
                    </P>
                    <P>As stated in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023), we identified EtO as the cancer risk driver from HON sources; and we are aware of 15 HON facilities reporting more than 0.1 tpy of EtO emissions in their emissions inventories from HON processes and two other facilities that are new or under construction with HON processes that we expect will exceed this threshold (but for which we do not yet have emissions inventory information). Of these 17 facilities, 12 facilities produce and emit EtO, which is a process subject to the HON MACT standards. In addition, all 17 of these facilities have additional HON processes that use and emit EtO in the production of glycols, glycol ethers, or ethanolamines. Therefore, we are not imposing EtO controls across the entire SOCMI source category. Rather, in order to reduce emissions of EtO from HON processes, the EPA is finalizing more stringent control requirements for process vents, storage vessels, equipment leaks, heat exchange systems, wastewater, maintenance vents, and PRDs that emit or have the potential to emit EtO. While it is true from our residual risk assessment that eight of the 17 facilities with emissions of EtO from various HON processes have cancer risks above 100-in-1 million, the standards are national standards that apply to specific types of sources rather than specific facilities, and the revisions ensure that risks from the source category are acceptable and that the standards provide an ample margin of safety to protect public health. As such, we disagree with the commenter that we should target additional controls on only facilities that pose unacceptable risk.</P>
                    <P>
                        For these same reasons, we also disagree with the commenter that adopting the MON definition of “in ethylene oxide service” results in new EtO emissions standards that apply to approximately twice as many affected facilities as needed to address the risk that the EPA determines to be actionable. Although, as noted in our proposal, similar emission sources and standards exist between the HON and MON, we disagree with the commenter that we did not give any consideration

                             The commenter stated that the MERP was installed to route vent emissions from the monomer process unit to the facility's halogen acid production furnace. The MERP is essentially a complex of vent headers (with condensate collection posts) to route emissions predominately from the Monomer area of the Neoprene Facility, as well as emissions from nine permitted hazardous waste tanks (containing liquid hazardous wastes) to the facility's halogen acid production furnace. The MERP conveys approximately 300 to 600 CFM of chloroprene vent emissions from currently “Group 2” classified emission units under the HON subpart G. Stack tests have demonstrated a 99.3 percent destruction or removal efficiency for the halogen acid production furnace.

                        During the first six months of 2016, the facility engaged in numerous meetings with both the EPA and the LDEQ to discuss options for reducing chloroprene emissions, including different types of control devices. Records of these discussions show that, in October 2016, the facility presented slides to the EPA and the LDEQ that summarized control device options, including a direct-fired thermal oxidizer (the only option that could achieve a chloroprene destruction efficiency of 99.9 percent) and an RTO, which was expected to have a chloroprene destruction efficiency of 98 percent. As the slide indicated, however, the cost of operating a direct-fired thermal oxidizer would be very high because it would burn enormous amounts of natural gas. This is why in June 2016, the facility proposed to install an RTO, which would have similar up-front capital costs but would have much lower operating costs (and much lower CO
                        <E T="52">2</E>

                        In December 2016, the LDEQ held a large public meeting at its headquarters, with the EPA and the Department of Justice in attendance. Before this meeting, an EPA researcher advised EPA officials that, to achieve a risk-level of 1-in-10,000, ambient concentrations of chloroprene in the community could be no higher than 0.2 ug/m
                        <SU>3</SU>
                        . His memorandum making this assertion was also released publicly. At this meeting, the facility presented results of an air dispersion modeling study, which showed then-existing (2016) ambient concentrations and the concentrations that would be expected if the facility implemented the emission reduction projects it had proposed, including the installation of an RTO with a chloroprene destruction efficiency of 98 percent. The modeling results presented to the EPA, the LDEQ, and the public showed that offsite concentrations would be significantly reduced but would still be higher than 0.2 ug/m

                    <P>Following the public hearing, the facility, the EPA, and the LDEQ finalized the terms of a voluntary Administrative Order on Consent, which the facility and the LDEQ signed on January 6, 2017. The EPA and lawyers from the Department of Justice were present for all significant discussions, and the EPA was heavily involved in the Administrative Order on Consent's development, providing numerous comments and making a number of demands reflected in the order. Under the Administrative Order on Consent, the facility agreed to “install and operate . . . a Regenerative Thermal Oxidizer (RTO)” capable of “achiev[ing] at least a 98 percent [destruction or removal efficiency].” The facility also agreed to install the MERP and to achieve an 85 percent reduction in total chloroprene emissions from the facility, principally from the “Chloroprene” Unit, to the facility's halogen acid production furnace.</P>
                    <P>The commenter claimed that these projects reduced facility chloroprene emissions by 85 percent at a capital cost of $35 million, plus a significant increase in annual operating costs; and of the $35 million, the MERP cost approximately $9 million. The commenter requested that the EPA take this history into account as it develops the final rule given that it is unreasonable to ignore the investments that the facility recently made to reduce chloroprene emissions when they were made under the oversight of the LDEQ and the EPA, and with the EPA's full knowledge of the 2010 IRIS inhalation URE value for chloroprene. The commenter contended that the very small emission reductions that would be achieved by increasing the chloroprene destruction efficiency to 99.9 percent are enormously expensive, more than $21 million per ton annually. The commenter said the current chloroprene emissions from the existing RTO are approximately 0.84 tpy; therefore, if all the emission streams currently routed to the existing RTO were instead routed to a new direct-fired thermal oxidizer with a chloroprene destruction efficiency to 99.9 percent, chloroprene emissions would be reduced from 0.84 tpy to 0.04 tpy (an annual reduction of 0.79 tons). The commenter claimed that the annualized cost of achieving this is almost $3.7 million, and the cost-per-ton of chloroprene emission reduction would be more than $4.6 million. The commenter submitted a similar analysis for their MERP system and claimed that if all the vent streams currently controlled by the MERP were instead routed to a control device with a chloroprene destruction efficiency of 99.9 percent (testing has demonstrated that the MERP achieves a destruction or removal efficiency of 99.3 percent on an overall basis), the reduction in annual chloroprene emissions would be 50-60 pounds, depending on production.</P>
                    <P>
                        The commenter said that they hired consultants to evaluate multiple options for control device configuration that would achieve a chloroprene destruction efficiency of 99.9 percent as required by the proposed rule. The commenter said that modifying their existing RTO to achieve a chloroprene destruction efficiency of 99.9 percent is 
                        <PRTPAGE P="42985"/>
                        not possible given that high levels of chlorine in their exhaust streams would poison the catalyst. The commenter added that even if their existing RTO could achieve a chloroprene destruction efficiency of 99.9 percent, it does not have capacity to accommodate the additional streams that would have to be routed to it under the proposed rule; thus, the proposed rule would require the installation of one or more new control devices that could accommodate very high air flows containing very low concentrations of VOC, including chloroprene. The commenter provided specific details of other control options and acknowledged that the destruction efficiency of an RTO can be increased to 99.9 percent by adding an additional oxidation step (which involves the installation of a polishing catalyst bed in the stack that reheats the treated gas); however, the commenter asserted that all other options that they evaluated (
                        <E T="03">e.g.,</E>
                         installing new RTOs and/or direct fired thermal oxidizers) would require enormous amounts of fuel consumption, quench water, and power consumption only to achieve minimum reductions.
                    </P>
                    <P>The commenter asserted that the EPA's cost estimate to install a new direct fired thermal oxidizer is “far from realistic” given that their consultant estimated the equipment purchase costs for a new direct fired thermal oxidizer with recuperative heat exchange capabilities would be approximately $12 million and total annual costs of $39 million. The commenter said the EPA assumed a slightly smaller direct fired thermal oxidizer than what they believe would be necessary and the EPA estimated an equipment purchase cost of $5 million and total annual costs of $10.1 million; however, the commenter asserted that it is not clear if the EPA's estimate includes the additional scrubber capacity or the high nickel alloy materials that would be needed for certain components. The commenter added that the EPA has not estimated the costs that would be required to upgrade the electrical and natural gas infrastructure, or expand the wastewater treatment plant (WWTP), which are all actions that would be necessary to install a new direct fired thermal oxidizer.</P>
                    <P>In summary, the commenter claimed that given that it is not possible to modify their existing RTO and MERP to achieve a chloroprene destruction efficiency of 99.9 percent, the proposed rule would leave the facility with $35 million of stranded investment which was made fewer than 6 years ago to reduce chloroprene emissions in consultation with the EPA. The commenter said that even though the option of installing a direct-fired thermal oxidizer was discussed in 2016, at no point did the EPA suggest that an RTO would not be sufficient or that a direct-fired thermal oxidizer might be required. The commenter asserted that there has been no change since 2016 in either (1) the EPA's views about the risk of chloroprene exposure or (2) its understanding of the offsite concentrations that would be achieved under the Administrative Order on Consent.</P>

                         We reevaluated whether we could change the proposed 99.9 percent by weight reduction standard to 98 percent by weight given the commenter's arguments that their existing RTO and MERP cannot achieve a chloroprene reduction of 99.9 percent by weight. In our reevaluation for the final rule, we determined that revising the performance standard for process vents and storage vessels in chloroprene service (from a 99.9 percent by weight reduction requirement as proposed to a 98 percent by weight reduction requirement in the final rule) will still maintain the MIR at 100-in-1 million for the Neoprene Production source category and thereby result in the source category chloroprene emissions being reduced to acceptable levels. We have made this change in the final rule at 40 CFR 63.484(u)(1), 40 CFR 63.485(y)(1), 40 CFR 63.487(j)(1), and 40 CFR 63.510(a)(2). While considering the current chloroprene emissions from both the existing RTO (0.84 tpy) and MERP (0.02 tpy based on our review of the emissions inventory calculations), we have determined the revised performance requirements for the final rule will still reduce risk from Neoprene Production source category emissions to an acceptable level and also provide an ample margin of safety to protect public health (as was proposed) for the Neoprene Production source category. We also have determined that no additional requirements are needed to prevent an adverse environmental effect (as was proposed). In light of this, we believe the commenter's existing RTO and MERP can be used to meet the revised requirements for the final rule and would no longer be considered a stranded investment as the commenter has claimed.

                         A commenter said they support the EPA's proposed rule text at 40 CFR 63.485(y) that requires owners and operators to reduce emissions of chloroprene from continuous front-end process vents in chloroprene service at affected sources producing neoprene by venting emissions through a closed-vent system to a non-flare control device that reduces chloroprene by greater than or equal to 99.9 percent by weight, to a concentration less than 1 ppmv for each process vent, or to less than 5 lb/yr for all combined process vents. The commenter said they also support the EPA's proposed rule text at 40 CFR 63.487(j) to add these same chloroprene standards for batch front-end process vents at affected sources producing neoprene. However, another commenter argued that the EPA's oversimplification of the design configurations necessary to comply with these proposed performance standards (which the EPA presented in Docket Item No. EPA-HQ-OAR-2022-0730-0083) results in cost estimates that are much too low. The commenter asserted the EPA did not consider in their analysis the following technical and process safety challenges:
                    </P>
                    <P>• The EPA assumed that all the sources at this commenter's facility are to be enclosed and routed to a new direct fired thermal oxidizer are in close proximity to each other, but the wash belts are actually located in the Finishing building, which is separate from the Poly building.</P>
                    <P>
                        • The EPA did not account for complicated duct and piping (

                         unique pipe lengths, diameters, number of bends), which also impacts pump specifications and other equipment such as the blower.
                    </P>
                    <P>• The existing thermal oxidizer cannot accommodate the additional vent streams from the wash belts (at current flow rates). Each wash belt vent hood operates at approximately 28,000 standard cubic feet per minute (scfm), and total chloroprene emissions for both wash belt vents combined is approximately 3.3 tpy (2022 reported value).</P>
                    <P>• Installing an enclosure around the wash belts creates safety concerns given that the wash belt blower motors are equipped with variable frequency drives which can change air flow through the vent hoods; the potential variability in air flows would need to be evaluated by an industrial hygienist to ensure compliance with personnel exposure requirements, or to make recommendations for additional protective equipment.</P>
                    <P>• Wash belts require frequent, manual intervention from area personnel to ensure stable operation; workers must have physical access to the wash belt area to perform routine maintenance and repairs.</P>
                    <P>
                        • Wash belt enclosures would need to be transparent to allow visual inspection of the process without entry and would also need to be durable enough to withstand frequent disassembly and reassembly.

                    </P>
                    <P>• Any changes in airflows or pressures, such as those that will occur when installing enclosures and adjusting blower speeds (for the wash belts), will need to be evaluated to ensure that product quality standards are achievable and to ensure that production rates are not negatively impacted. The finishing process is designed to supply very precise air flows and pressure differentials throughout in order to maintain adhesion of the web (Neoprene product film) to the girt (flexible sheeting that guides the web through the process).</P>

                        The commenter submitted a cost estimate of $3.6 million for the purchase of a direct fired thermal oxidizer with a chloroprene destruction efficiency of 99.9 percent that would be sized to accommodate waste gas from the wash belts. The commenter estimated the total cost for installing and operating the thermal oxidizer would be about $18 million. The commenter asserted that because of the low VOC content in the exhaust stream, natural gas consumption would be high, and the total annualized costs would be almost $3.0 million (not including the capital costs for the enclosure and associated infrastructure). The commenter stated that the cost-per-ton of chloroprene emission reduction would be approximately $0.9 million (based on the 3.3 tpy of chloroprene emissions reported in their 2022 inventory).

                        As discussed in the preamble to the proposed rule (see 88 FR 25080, April 25, 2023), we had determined that the only viable way to meet these proposed standards is to enclose all of the polymer batch reactors, emulsion storage vessels, strainers, and wash belt dryers and route the vapors to a thermal oxidizer (and thereby reduce chloroprene emissions from these sources, which are fugitive in nature); and the result of this control option would reduce chloroprene emissions from the polymer building, unstripped resin emulsion storage vessels, and wash belt dryers by 11.3 tpy (from 12 tpy to 0.7 tpy). Although we continue to stand by our analysis that chloroprene emissions from these emission sources must be reduced to decrease risk posed by emissions from neoprene production processes to an acceptable level, we reevaluated whether we could change the 99.9 percent by weight reduction standard to 98 percent by weight given a commenter's arguments (as discussed in section 3.1 of the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>

In our reevaluation for the final rule, we determined that revising the performance standard for process vents and storage vessels in chloroprene service (from a 99.9 percent by weight reduction requirement as proposed to a 98 percent by weight reduction requirement in the final rule) will still maintain the MIR at 100-in-1 million for the Neoprene Production source category. The result of this revision in the final rule will reduce chloroprene emissions from the polymer building, unstripped resin emulsion storage vessels, and the wash belt dryers from 12 tpy to 0.9 tpy (

We have determined these revised performance requirements for the final rule will still reduce risk to an acceptable level and also provide an ample margin of safety to protect public health (as was proposed) from P&amp;R I emission sources. We also have determined that no additional requirements are needed to prevent an adverse environmental effect (as was proposed).

                        We also acknowledge that the wash belt dryers are located in the finishing building, which is separate from the polymer building; and at proposal, we incorrectly assumed these process vents were front-end process vents when in actuality they are considered back-end process vents according to NESHAP subpart U. As such, we are clarifying in the final rule that the requirements we are finalizing for controlling chloroprene from process vents in the Neoprene Production source category, not only applies to continuous front-end process vents in chloroprene service and batch front-end process vents in chloroprene service, but also back-end process vents in chloroprene service. In other words, we are finalizing at 40 CFR 63.494(a)(7) a requirement that owners and operators reduce emissions of chloroprene from back-end process vents in chloroprene service at affected sources producing neoprene by venting emissions through a closed-vent system to a non-flare control device that reduces chloroprene by greater than or equal to 98 percent by weight, to a concentration less than 1 ppmv for each process vent, or to less than 5 lb/yr for all combined process vents. We anticipate that the facility will still need to install an additional thermal oxidizer in order to comply with the final performance standard for process vents and storage vessels in chloroprene service. We also note that while the commenter claims that the 3.3 tpy chloroprene emissions from the wash belt dryers were reported in their 2022 inventory, we stand by our decision to use the facility's 2019 emissions inventory which shows 3.9 tpy chloroprene emissions from the wash belt dryers. As previously mentioned, the facility's emissions inventory was provided to the EPA pursuant to our CAA section 114 request. In particular, the EPA requested emission inventories from the past 5 years (
                        <E T="03">i.e.,</E>
                         2016-2020) from the facility's operations as part of this request. As 2017 NEI data did not represent current controls being employed at Denka Performance Elastomers, LLC, the EPA chose to use the most current data it had available and that is reflective of current operations and emissions. Given concerns about decreased production and emissions in 2020 from the COVID-19 pandemic, the EPA elected to use Denka Performance Elastomer, LLC's 2019 emissions inventory submitted as part of the CAA section 114 request in its risk assessment for the SOCMI and Neoprene Production source categories in lieu of the 2017 NEI data. Even if we were to revise emissions based on the facility's 2022 emissions inventory, we continue to believe our cost estimate to install permanent total enclosures, a thermal oxidizer, and ductwork and associated support equipment (using the procedures in the EPA's 2002 Control 
                        <PRTPAGE P="42987"/>
                        Cost Manual) is reasonable, and note that cost does not play a role in setting standards that are necessary to reduce risk to an acceptable level under step one of the Benzene NESHAP approach codified in CAA section 112(f). Furthermore, with regard to a commenter's specific objections to installing a permanent total enclosure around their wash belts/dryers, we note that even though we costed out permanent total enclosures for these emission sources in our proposal, there is no explicit requirement in the proposed rule, or final rule, to install permanent total enclosures around these emission sources. We opted for this option as the most conservative way to collect the fugitive chloroprene emissions from the wash belts/dryers and route them to a control device such as a thermal oxidizer. Nothing in the proposed rule, or final rule, prevents the facility from doing something different than installing a permanent total enclosure around their wash belts/dryers so long as the owner or operator can achieve the emission standard we are finalizing at 40 CFR 63.494(a)(7) for back-end process vents (
                        <E T="03">i.e.,</E>

                    <P>Even so, we anticipate cost to be less of a concern for the final rule given that the facility should be able to use their existing thermal oxidizer to meet the revised performance standard (reduce chloroprene by greater than or equal to 98 percent by weight) for at least some of their process vents and storage vessels in chloroprene service.</P>

                        <E T="03">Comment:</E>
                         A commenter said that they support the proposed provision at 40 CFR 63.501(a)(10)(iv) to revise the Group 1 wastewater stream threshold to include wastewater streams in chloroprene service (
                        <E T="03">i.e.,</E>
                         wastewater streams with total annual average concentration of chloroprene greater than or equal to 10 ppmw at any flow rate). However, another commenter said the EPA's analysis of the costs and emission reductions associated with reducing chloroprene emissions from wastewater streams at neoprene production processes (see Docket Item No. EPA-HQ-OAR-2022-0730-0092) has several major flaws. The commenter said the EPA's analysis suggests that the proposed control requirements for wastewater would reduce chloroprene emissions by 17.7 tpy, when in fact the emission reductions would be closer to 1 tpy; therefore, the EPA's analysis substantially overstates the emission reductions that would be achieved, and the efficacy and cost-effectiveness of the proposed requirements at 40 CFR 63.501(a)(10)(iv). The commenter provided the following critiques of the EPA's analysis:
                    </P>
                    <P>• there are approximately 13.5 tpy of wastewater in chloroprene service that pass through the WWTP, not 26.3, which the EPA incorrectly used in their analysis.</P>
                    <P>• although the EPA acknowledges that some controls may already be in place, their analysis goes on to analyze the effectiveness of the proposed requirements based on the assumption that there are no such controls; however, the facility already employs an air stripping system to treat the decanter and kettle line wastewater streams. The air stripping occurs in the air sparging tank, which is routed to the onsite RTO. Testing suggests that the air sparging tank achieves a control efficiency of approximately 95 percent. Thus, of the 7.5 tpy of chloroprene contained in these 2 streams, all but ~0.4 tpy are removed via air stripping and directed to RTO. This amount, ~0.4 tpy, then goes to the WWTP, which includes a biological treatment system that reduces it by approximately 80 percent, meaning that chloroprene emissions from the decanter and kettle line streams are likely less than 0.1 tpy. Thus, accounting for the control efficiency of the air sparging tank and the biologic treatment system, almost 99 percent of the 7.5 tpy contained in the decanter and kettle line wastewater streams is already controlled. Even if steam stripping achieves a 99 percent capture efficiency in these streams, it would only reduce emissions by about 0.025 tpy (to 0.075 tpy as compared to 0.1 tpy today).</P>
                    <P>• based on limited testing of the air stripper rundown streams, they contain approximately 6.0 tpy of chloroprene. These streams are routed to the outdoor brine pit, which then discharges to the WWTP. The EPA did not consider that the WWTP includes biological control that currently reduces chloroprene emissions by approximately 80 percent. It is true that some emissions to air occur as the wastewater is conveyed through the outdoor brine pit and to the WWTP, but it is incorrect for the EPA to consider it “uncontrolled.” Assuming the Fe of 68 percent suggested by the EPA, the maximum fraction of the mass of chloroprene that could end up as an air emission is about 4 tpy before biological control. Applying the 80 percent estimated biological control removal rate, current emissions are approximately 0.8 tpy from the air stripper rundown streams. Even if the EPA's assumption of a 99 percent removal efficiency for steam stripping is accurate, it would reduce emissions by about 0.8 tpy from the stripper rundown streams.</P>
                    <P>The commenter concluded that when adding the 0.8 tpy from the stripper rundown streams to the 0.1 tpy reduction from the decanter and kettle line wastewater streams, the EPA's proposed steam stripping requirement is likely to reduce current chloroprene emissions by about 1 tpy (not by 17.7 tpy as the EPA had determined). The commenter added that there is also uncertainty as to whether steam stripping would actually achieve 99 percent removal of the low concentrations of chloroprene in wastewater given that chloroprene is a halogenated alkane, and no information has been presented that is specific to steam stripping of chloroprene from wastewater at the concentrations present in wastewater at the facility. The commenter deduced that when using their expected actual emissions reductions of about 1 tpy, the cost effectiveness would be closer to $7.5 million per ton removed (without considering the cost of installing and operating a thermal oxidizer that would be required under the EPA's proposal to handle the chloroprene from the steam stripper unit), and not $426,900 per ton as the EPA has estimated.</P>

                        <E T="03">Response:</E>
                         The EPA acknowledges the commenters' support for and opposition of the proposed wastewater provisions at 40 CFR 63.501(a)(10)(iv). We are finalizing these provisions as proposed. We disagree with the commenter's assertion that 13.5 tpy of wastewater in chloroprene service pass through the WWTP. We also disagree that our emissions reductions were overestimated. We believe 26.3 tpy of wastewater in chloroprene service pass through the WWTP (
                        <E T="03">i.e.,</E>
                         the amount of chloroprene entering the air sparging tank) based on our review of emissions inventory calculations for wastewater entering the WWTP. We maintain that 17.7 tpy of emissions reductions is appropriate, based on a mass balance of the information provided in the emissions inventory calculations. The results of our mass balance suggest that our initial analysis is appropriate.
                    </P>
                    <P>
                        We also disagree with the commenter and maintain it was appropriate to 
                        <PRTPAGE P="42988"/>
                        assume no controls during our initial analysis such that a steam stripper would be placed before the air sparging tank. Simply put, the P&amp;R I NESHAP (which references the HON wastewater requirements) requires all wastewater collection system components (tanks, surface impoundments, containers, individual drain systems, and oil-water separators) to be covered and upstream of the wastewater treatment process. However, the facility's wastewater treatment system is configured with an air sparging tank (air stripper), followed by an outdoor brine pit (open to the atmosphere), followed by biological treatment. Furthermore, the commenter claims their air stripper achieves approximately 95 percent control, but did not provide any data to corroborate this control efficiency. When taking the configuration of the facility's wastewater treatment system into account, we assumed no controls, since wastewater streams flow through a control device with an unknown control efficiency directly into an open brine pit.
                    </P>
                    <P>
                        Also, contrary to the commenter's remark regarding steam stripper performance, we believe the use of 99 percent removal of chloroprene from steam stripping is appropriate based on its Fr value. In the document titled 
                        <E T="03">Analysis of Control Options for Wastewater Streams to Reduce Residual Risk of Chloroprene from Neoprene Production Processes Subject to P&amp;R I</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0092), we explain that the EPA calculated the Fr values for a variety of HAP during the original rulemaking of the HON. The Fr is the fraction of a HAP that is stripped from wastewater and is an indicator of the extent to which a HAP is effectively removed during the steam stripping process. For chloroprene, the Fr has always been 99 percent in Table 9 to NESHAP subpart G and we maintain this is reflective of the current technology.
                    </P>
                    <P>Finally, we remind the commenter that, due to the risk associated with chloroprene, cost does not play a role in setting standards that are necessary to reduce risk to an acceptable level under step one of the Benzene NESHAP approach codified in CAA section 112(f). Regardless of whether or not emissions reductions were underestimated (which we disagree with), a higher cost-effectiveness is not grounds for reevaluating the proposed provisions at 40 CFR 63.501(a)(10)(iv).</P>

                        <E T="03">Comment:</E>
                         A commenter said they support the EPA's proposed rule text at 40 CFR 63.483(a)(10) that requires owners and operators to comply with a facility-wide chloroprene emissions cap of 3.8 tpy in any consecutive 12-month period for all neoprene production emission sources. However, another commenter argued that it is impossible to know whether the chloroprene emissions cap of 3.8 tpy is simply a “backstop” or an additional requirement that goes beyond the proposed requirements to control emissions of chloroprene from maintenance vents and PRDs, and process vents, storage vessels, and wastewater “in chloroprene service.” The commenter asserted that the EPA does not appear to have determined whether full compliance with the proposed requirements to control chloroprene from maintenance vents and PRDs, and process vents, storage vessels, and wastewater “in chloroprene service” would reduce the facility-wide emissions below the proposed chloroprene emissions cap of 3.8 tpy. The commenter also asserted that the EPA has not estimated the costs of reducing facility-wide emissions below this cap, nor does the EPA provide any details about the type of monitoring that would be required to demonstrate compliance with it. The commenter argued that given the EPA's determination that the chloroprene emissions cap of 3.8 tpy would protect public health with an ample margin of safety, the proposed requirements to control chloroprene from maintenance vents and PRDs, and process vents, storage vessels, and wastewater “in chloroprene service” are unlawful if they would force the facility to reduce emissions appreciably below 3.8 tpy. The commenter said that the EPA does not have authority to require emission reductions that go beyond what is necessary to protect public health with an ample margin of safety, unless they are based on cost-effective improvements in control technology under CAA section 112(d)(6).

                    <P>
                        Another commenter provided several reasons why the chloroprene emissions cap of 3.8 tpy is inappropriate, including: (1) The EPA back-calculated this cap from a flawed risk assessment; (2) the cap is unverifiable and therefore not enforceable, particularly here where it encompasses not only non-flare point sources (which can, with some effort, be properly monitored) but also flare and numerous fugitive sources (whose emissions simply cannot be tested, monitored, and verified); and (3) there have recently been large problems with “unknown” and therefore unreported emissions at the facility (

                         We are not finalizing the proposed requirement at 40 CFR 63.483(a)(10) that would have required owners and operators to comply with a chloroprene emissions cap of 3.8 tpy in any consecutive 12-month period for all neoprene production emission sources. The proposed facility-wide chloroprene emissions cap was intended to address unknown or uncertain emission sources in the Neoprene Production source category, including emissions from back-end process operations. However, we agree with a commenter that the proposed facility-wide chloroprene emissions cap is confusing on how it would be applied beyond the proposed requirements for emission sources in chloroprene service. Instead, we believe the fenceline monitoring requirements that we are finalizing will serve as a reasonable backstop for limiting emissions and addressing fugitive and any unknown emission sources in the Neoprene Production source category as well as whole-facility chloroprene emissions. We are also clarifying in the final rule that the requirements we proposed for controlling chloroprene from process vents in the Neoprene Production source category apply not only to continuous front-end process vents in chloroprene service and batch front-end process vents in chloroprene service, but also to back-end process vents in chloroprene service. For more details about this, see our responses to comments in section IV.A.3.e.i of this preamble.

                         The EPA acknowledges the commenter's support of the sampling and analysis procedures used to determine whether process equipment is “in chloroprene service.” We are making the following minor changes in the final rule to clarify our intent: (1) For process vents, we have clarified within the definition of “in chloroprene service” that the 5 lb/yr chloroprene mass threshold for combined process vents be on a EPPU-by-EPPU basis; (2) For storage vessels, we are revising the phrasing of “sampling and analysis is performed as specified in § 63.509”

                         A commenter (0172) requested that the EPA recognize in the final rule that OGI is effective for detecting chloroprene leaks and work with their facility to develop a protocol for LDAR that could be included as a compliance option. The commenter claimed that the LDAR requirement in the proposed rule would require them to hire additional technicians (likely 3 additional workers) and purchase additional equipment. The commenter said that they spoke to leak detection experts at Montrose Environmental who said that a forward looking infrared cooled G304 camera would likely be an effective tool for monitoring and detecting chloroprene leaks. The commenter stated that they completed a one-day field test with such a camera and found that it was effective for detecting chloroprene leaks.

                         We did not propose control options for equipment leaks to reduce chloroprene risk from the Neoprene Production source category. To reduce risk from the Neoprene Production source category to an acceptable level, we proposed to require control of chloroprene for: (1) Process vents, (2) storage vessels, and (3) wastewater “in chloroprene service.” We also proposed requirements to reduce chloroprene emissions from maintenance vents and PRDs. See section III.B.2.b of the preamble to the proposed rule for more details (88 FR 25080, April 25, 2023). However, we did make an error in the document titled 
                        <E T="03">Proposed Regulation Edits for 40 CFR part 63 Subpart U: National Emission Standards for Hazardous Air Pollutant Emissions: Group I Polymers and Resins</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0066) that suggests at 40 CFR 63.502(a)(6) we were proposing to regulate certain equipment in chloroprene service.
                    </P>
                    <P>The EPA has not provided an OGI-only option for detection for chloroprene leaks. Although the commenter mentions a one-day study performed by Montrose Environmental on the effectiveness of a particular OGI camera's ability to see chloroprene emissions, no information from that study was submitted. Additionally, no information on the detection level determined during the study or the environmental conditions of the study were submitted. Because the detection capabilities of OGI cameras are highly influenced by environmental conditions, this is important data to understand, and it is unlikely that a one-day study would provide information on the capabilities of the camera in the range of environmental conditions under which field surveys would normally be conducted.</P>
                    <P>Although the EPA recently finalized a protocol for using OGI in the detection of VOC and methane leaks (40 CFR part 60 appendix K), we note that the protocol is geared towards midwave OGI cameras that operate with a filter in a particular spectral range (around 3.3 microns) where methane and many VOC compounds have a spectral peak. The type of OGI camera the protocol is geared towards is not suited to finding leaks of chloroprene because chloroprene does not have a strong peak in the spectral range of these cameras, which means that only very high leaks of chloroprene would be visible to these cameras. The OGI camera mentioned by the commenter has a filter in a different spectral range. The EPA has not studied this camera to understand its detection capabilities, especially in regard to chloroprene, which is a risk driver for the source category, nor could the EPA readily find information on the ability of this OGI camera to see leaks of chloroprene. Because the leak definitions for the source category are low, on the order of 500 to 1000 ppm for most equipment, it is extremely important to understand the detection capability of an OGI camera being used at these sources, especially considering that while the OGI cameras the EPA has studied are effective at finding large leaks for many compounds, OGI cameras tend to be less effective at finding low-level leaks.</P>
                    <P>Even so, P&amp;R I facilities currently have an option to use OGI through an alternative work practice to detect leaks from equipment at 40 CFR 63.11(c), (d), and (e). This alternative work practice includes provisions for using OGI in combination with annual monitoring using EPA Method 21 (and not as an alternative). The alternative work practice is not geared towards a particular type of OGI camera, and instead, requires owners and operators to perform daily instrument checks based on the detection levels and concentration of detectable chemicals in the equipment being surveyed.</P>

                        As noted in our proposal, the EPA sets standards under CAA section 112(f)(2) using “a two-step standard-setting approach, with an analytical first step to determine an `acceptable risk' that considers all health information, including risk estimation uncertainty, and includes a presumptive benchmark on maximum individual lifetime risk (MIR) of approximately 1-in-10 thousand” (88 FR 25080, April 25, 2023; see also 54 FR 38045, September 9, 1989.)

In addition, the source category-specific decision of what constitutes an acceptable level of risk should be a holistic one; that is, it should simultaneously consider all potential health impacts—chronic and acute, cancer and noncancer, and multipathway—along with their uncertainties, when determining the acceptable level of source category risk.

We updated the risk assessment for the SOCMI and Neoprene Production source categories considering the comments received on modeling flares. The revised risk assessment (see the risk reports,

                    <P>Based on our technology review for the SOCMI, P&amp;R I, and P&amp;R II source categories, we proposed under CAA section 112(d)(6) changes to the HON and P&amp;R I standards for heat exchange systems, storage vessels, and process vents and we proposed no change under CAA section 112(d)(6) to the P&amp;R II standards for storage vessels and process vents. The P&amp;R II NESHAP currently does not regulate HAP emissions from heat exchange systems, but we are finalizing, as proposed, requirements in the P&amp;R II NESHAP for heat exchange systems pursuant to CAA section 112(d)(2) and (3). In addition, we proposed no change under CAA section 112(d)(6) for transfer racks, wastewater streams, and equipment leaks. We also proposed fenceline monitoring requirements under CAA section 112(d)(6). We provide a summary of our findings, as proposed, in this section.</P>

                        In our technology review for the SOCMI, P&amp;R I, and P&amp;R II source categories, we identified one development in practices and processes for HON and P&amp;R I heat exchange systems, the use of the Modified El Paso Method

                        <FTREF/>
                         for monitoring for leaks from heat exchange systems. We determined that this method is more effective in identifying leaks and measures a larger number of compounds than the methods previously required in the HON and the P&amp;R I NESHAP. After evaluating state and Federal regulations requiring the Modified El Paso Method, as well as emission data collected for the Ethylene Production RTR (refer to section II.D of the proposal preamble (88 FR 25080, April 25, 2023) and the Ethylene Production RTR rulemaking docket, Docket ID No. EPA-HQ-OAR-2017-0357), we proposed pursuant to CAA section 112(d)(6) to require use of the Modified El Paso Method with a leak definition of 6.2 ppmv of total strippable hydrocarbon concentration (as methane) in the stripping gas to further reduce HAP emissions from both new and existing heat exchange systems, as well as to disallow delay of repair of leaks if the measured concentration meets or exceeds 62 ppmv. Based on an evaluation of incremental HAP cost effectiveness to increase the monitoring frequency, we proposed no changes to the monitoring frequency previously required under the HON and the P&amp;R I NESHAP for monitoring for leaks from heat exchange systems, which continues to be monthly monitoring in the first 6 months following startup of a source and quarterly monitoring thereafter. We also proposed to require re-monitoring at the monitoring location where a leak is identified to ensure that any leaks found are fixed. Further, we proposed that none of these proposed requirements for heat exchange systems apply to heat exchange systems that have a maximum cooling water flow rate of 10 gallons per minute or less. Finally, we proposed that owners and operators may use the current leak monitoring requirements for heat exchange systems at 40 CFR 63.104(b) in lieu of using the Modified El Paso Method provided that 99 percent by weight or more of the organic compounds that could leak into the heat exchange system are water soluble and have a Henry's Law Constant less than 5.0E-6 atmospheres-cubic meters/mol at 25 degrees Celsius. Refer to section III.C.1 of the proposal preamble (88 FR 25080, April 25, 2023) for a summary of our rationale for selecting the proposed leak method, leak definition, and limitation on delay of repairs, as well as our rationale for retaining the previous monitoring schedule.

Refer to section III.C.3.b of the proposal preamble (88 FR 25080, April 25, 2023) for a detailed summary of these advances in process operations. Based on our evaluation of statutory factors, including costs and emission reductions, we proposed pursuant to CAA section 111(b)(1)(B) revised NSPS subparts IIIa, NNNa, and RRRa (which are applicable to affected facilities for which construction, reconstruction, or modification commences after April 25, 2023). We proposed that the revised NSPS subparts encompass a suite of process vent requirements, which include: (1) Removing the TRE index value concept in its entirety and instead requiring owners and operators to reduce emissions of TOC (minus methane and ethane) from all vent streams of an affected facility (
                        <E T="03">i.e.,</E>

We are also finalizing: (1) Burden reduction measures to allow owners and operators to skip fenceline measurement periods for specific monitors with a history of measurements that are at or below certain action levels; (2) a clarification that fenceline monitoring is required for owners and operators with affected sources that produce, store, or emit one or more of the target analytes; (3) a reduction in the requirements for the minimum detection limit of alternative measurement approaches; (4) clarifications on establishing the monitoring perimeter for both sorbent tubes and canisters; (5) clarifications on the calculation of Δc when a site-specific monitoring plan is used to correct monitoring location concentrations due to offsite impacts; (6) a change in the required method detection limit for alternative test methods from an order of magnitude below the action level to one-third of the action level; and (7) with the exception of fenceline monitoring of chloroprene at P&amp;R I affected sources producing neoprene, a change in the compliance date in the final rule to begin fenceline monitoring 2 years (instead of 1 year, as proposed) after the effective date of the final rule. For P&amp;R I affected sources producing neoprene, we have changed the compliance date for fenceline monitoring of chloroprene to begin no later than October 15, 2024, or upon startup, whichever is later, subject to the owner or operator seeking the EPA's authorization of an extension of up to 2 years from July 15, 2024.

                        <E T="03">Comment:</E>
                         A commenter said they supported the EPA's proposed rule text at 40 CFR 63.113(a)(4) and 40 CFR 63.485(l)(6), (o)(6), (p)(5), and (x) that removes the TRE concept in its entirety from both the HON and P&amp;R I NESHAP. However, numerous commenters opposed removal and provided the following arguments to reinforce their opposition:
                    </P>
                    <P>• The EPA lacks the statutory authority to remove the TRE index value concept because it has offered no supportable basis as to why removal would constitute a development in practices, processes, or technologies under CAA section 112(d)(6).</P>
                    <P>• The fact that another source category's standards do not include the TRE index value concept is not a development in practice, and the EPA offered no argument as to how it could possibly fit within that box.</P>
                    <P>• The fact that some facilities choose to control process vents that would be exempt using the TRE index value does not indicate that removing the TRE concept is a development in practices, processes, or technologies. Electing not to use the TRE is a business choice, not a technological development.</P>
                    <P>• Complexity of an established compliance tool is not a technological development.</P>
                    <P>• The EPA has not adequately supported its proposal to remove the TRE concept.</P>
                    <P>• While it is true that certain facilities may have designated process vents with a TRE index value above 1.0 as a Group 1 process vent, the reason behind this may not necessarily be voluntary or driven by the desire to avoid the TRE calculation, but rather facilities may be controlling these process vents to comply with state or local regulations regarding VOCs or to meet a best available control technology (BACT) limit.</P>
                    <P>• The EPA's rationale for eliminating the TRE index value from the HON rule due to variations in other MACT rules is flawed given that the EPA did not remove the TRE index value during the revision of the MON rule and distinguishing between Group 1 and Group 2 process vents in the Ethylene Production source category is irrelevant.</P>
                    <P>• Even though some process vents with a TRE index value above 1.0 are controlled at certain facilities, that does not imply that controlling all process vents with TRE index values above 1.0 is appropriate or cost-effective.</P>
                    <P>
                        • Facilities often use source test results to determine TRE calculation inputs (even for vent streams with a TRE index value greater than 4.0), and this approach is neither complex nor uncertain to interpret.
                        <PRTPAGE P="42993"/>
                    </P>
                    <P>
                        • Despite the EPA's assertion that enforcing the TRE index value “can be” arduous due to its theoretical nature, no instances have been provided where verifying a TRE index value calculation posed challenges for an agency or contradicted actual cost effectiveness at a facility. The number of inputs to the TRE index value calculation is proportional to the number of measurable organic compounds in the vent stream; and some facilities have very few organic compounds in process vents, so the inputs are minimal, and if those inputs are determined by other allowed methods (
                        <E T="03">e.g.,</E>
                         source tests, permit limits), then verification of these inputs is clearly not problematic.
                    </P>
                    <P>• Perceived complexity is not a basis for removing the option.</P>

                        • The TRE index value has been an integral part of many technology-based air standards since its initial development, serving as a mechanism for determining cost effectiveness and triggering the requirements for process vent control (see,

                         the preamble to the 1994 HON adoption, which states that the TRE concept is appropriate because it “can be used to reflect all possible combinations of various factors that affect emission rates and likelihood of current control” (59 FR 19416) and “would provide consistency between the HON[,] the recently issued [control techniques guidelines] for SOCMI process vents. . .[and] the applicability criteria for the three SOCMI process vents NSPS” (59 FR 19418)).
                    </P>
                    <P>• By considering the TRE index value, an owner or operator can allocate their resources more efficiently and concentrate efforts and resources on the vents that have the greatest potential for emission reduction, maximizing the overall environmental benefit. The TRE considers not only the organic HAP emissions but also the volumetric flow and net heating value of the vent gas stream, and thus it takes into consideration the practicality of controlling relatively small organic HAP emission streams using control devices like a flare or a vapor incinerator.</P>
                    <P>• Use of the TRE index value is a holistic approach that ensures that the most significant emission sources are targeted for control, leading to more effective pollution reduction.</P>
                    <P>
                        • Uncontrolled Group 2 process vent gas streams typically exhibit minimal emissions of HAP and VOC, possess a low net heating value, may contain steam or water vapor, and have varying volumetric flow rates. Directing these streams to an emission control device, if available in the CMPU capable of handling them, is a complex engineering problem and would yield negligible emissions reductions. Moreover, it would likely necessitate the addition of significant amounts of supplemental fuel to combust this type of stream and consequently result in additional emissions of carbon monoxide (CO), nitrogen oxides (NO

                    <P>• It is not clear how the emissions averaging program, as it is currently applied under the HON, can continue to exist with the requirement to control process vents that are currently designated as Group 2 vents. The burden of over-control to generate “credits” will effectively render the provisions unattainable or useless.</P>
                    <P>• Many facilities will still be required to comply with TRE-based determinations according to their title V operating permits and requirements under NSPS subparts NNN and RRR.</P>
                    <P>Many of the commenters who opposed removing the TRE index value in its entirety suggested that the EPA could potentially consider raising the TRE index value threshold, such as by aligning it with the value in the MON rule or the value indicated in Option 3 of the proposed rule, or by setting it at a level agreed upon as cost-effective by the industry. Other commenters opposed this suggestion.</P>
                    <P>
                        <E T="03">Response:</E>
                         The EPA acknowledges commenters' support for and opposition to the removal of the TRE concept from the HON at 40 CFR 63.113(a)(4) and from the P&amp;R I NESHAP at 40 CFR 63.485(l)(6), (o)(6), (p)(5), and (x). We are finalizing the removal of the TRE concept as proposed. We stand by the rationale we provided in the preamble to the proposed rule (88 FR 25080, April 25, 2023) for removing the TRE concept: (1) We identified at least one more recent (than the HON and the P&amp;R I NESHAP) chemical manufacturing NESHAP (
                        <E T="03">i.e.,</E>
                         ethylene production) that does not use the TRE index value as criteria for determining whether a process vent should be controlled; (2) based on the responses to our CAA section 114 request, we observed that some facilities are controlling continuous process vents that are not required by the HON and the P&amp;R I NESHAP to be controlled per the results of the TRE index value calculation; (3) based on the responses to our CAA section 114 request, we observed that facilities are routing multiple continuous process vents to a single APCD; (4) determining a TRE index value for certain process vent streams is often theoretical, can be extremely complicated, and is uncertain; and (5) because the TRE index value is largely a theoretical characterization tool, it can be very difficult to enforce.
                    </P>
                    <P>We disagree with commenters that the removal of the TRE concept does not constitute a development in practices, processes, or technologies under CAA section 112(d)(6). We noted in the preamble to the proposed rule (88 FR 25080, April 25, 2023) that some owners and operators do not use the TRE index value to determine whether a vent stream is a Group 1 or Group 2 process vent. While we agree with commenters that owners and operators control Group 2 vent streams for reasons other than the desire to avoid the TRE calculation, the fact is that owners and operators are controlling HON and P&amp;R I Group 2 process vents (possibly to comply with state or local regulations regarding VOCs or to meet a BACT limit), which we consider a development under CAA section 112(d)(6). Given that the TRE concept, as some commenters pointed out, has been used since the original 1994 HON adoption (and even in the 1992 proposed HON rule), we consider owners and operators controlling HON and P&amp;R I Group 2 process vents to be an operational procedure that was not identified or considered during development of the original MACT standards. Additionally, the removal of the TRE concept simplifies the determination as to whether owners and operators must control a vent stream and thus the applicability process is easier to implement.</P>
                    <P>
                        We disagree with commenters' assertion that the EPA did not provide evidence that the TRE concept is largely theoretical and, as a result, difficult to verify. As identified in the document titled 
                        <E T="03">Clean Air Act Section 112(d)(6) Technology Review for Continuous Process Vents Located in the SOCMI Source Category that are Associated with Processes Subject to HON, Continuous Front-end and Batch Front-end Process Vents Associated with Processes Subject to Group I Polymers and Resins NESHAP, and Process Vents Associated with Processes Subject to Group II Polymers and Resins NESHAP</E>
                         (Docket Item ID No. EPA-HQ-OAR-2022-0730-0094), one facility that received the CAA section 114 request provided over 300 pages of modeled runs used to determine certain characteristics of their continuous process vents to be utilized as part of the TRE index value calculations. Reviewing this information revealed that in many cases the facility struggled to unify the modeled runs with actual conditions at the facility and in some cases made arbitrary decisions to allow the model to function. While we agree with commenters that the TRE index 
                        <PRTPAGE P="42994"/>
                        value can be derived from less theoretical methods, other responses to the CAA section 114 request did not indicate how parameters used in the TRE index value calculations were determined, and commenters did not provide sufficient information to show which methods were most common throughout industry. Given the theoretical nature of the TRE index value, the EPA maintains that verifying TRE index values is arduous because it can involve relying on significant process knowledge in order to confirm HAP compositions of vent streams, vent stream flowrates, vent stream net heating values, and hourly emissions. It may also require verification of other facility assumptions (
                        <E T="03">e.g.,</E>
                         operational conditions and constraints) especially if modeling was used.

                    <P>
                        We agree with commenters that the TRE index value has been an integral part of many technology-based air standards since its initial development. In fact, we said as much in the document titled 
                        <E T="03">Clean Air Act Section 112(d)(6) Technology Review for Continuous Process Vents Located in the SOCMI Source Category that are Associated with Processes Subject to HON, Continuous Front-end and Batch Front-end Process Vents Associated with Processes Subject to Group I Polymers and Resins NESHAP, and Process Vents Associated with Processes Subject to Group II Polymers and Resins NESHAP</E>
                         (Docket Item ID No. EPA-HQ-OAR-2022-0730-0094). The TRE concept is almost 40 years old as it was first introduced in a December 1984 EPA document (EPA-450/3-84-015; see attachment to Docket Item No. EPA-HQ-OAR-2022-0730-0094). However, even if it has been integral, certain aspects of its underlying development are clearly no longer applicable or appropriate. For example, the EPA stated in the 1984 supporting materials (EPA-450/3-84-015) that the Agency attempted to make the TRE index independent of inflation (
                        <E T="03">e.g.,</E>
                         the EPA assumed fixed relative costs of various resources, such as carbon steel and electricity), yet it is impossible to ignore inflation in the TRE calculations due to the time that has passed since it was developed (
                        <E T="03">e.g.,</E>
                         costs of carbon steel and electricity have undoubtedly increased since the development of the TRE index).
                    </P>
                    <P>Although the TRE index value may allow owners and operators to allocate resources efficiently and ensure that the most significant emission sources are targeted for control, the current use of the TRE index value is only based on controlling a single process vent with a single APCD. This is an unrealistic scenario when compared to how chemical manufacturing facilities actually control their process vents; and it is much more likely that a facility routes numerous process vents to the same APCD (and this is evident from observing the responses to our CAA section 114 request).</P>
                    <P>
                        We agree with commenters that the removal of the TRE concept may lead to emissions increases due to the use of supplemental fuel in new APCDs that are potentially needed to control Group 2 streams that are currently uncontrolled; and we acknowledged this in our preamble to the proposed rule (88 FR 25080, April 25, 2023) as well as in the RIA accompanying the proposal. However, based on other comments received and discussed elsewhere in this section of this document (regarding the use of low volumetric flow rates in our original proposed cost estimate), we revised our cost analysis to account for higher flow rates to the APCD. As a result of this flow rate adjustment, additional supplemental fuel was needed to control Group 2 vent streams that exhibit minimal emissions of HAP and VOC, possess a low net heating value, and may contain steam or water vapor. Even so, at proposal, we overestimated the amount of supplemental fuel that would be needed nationwide (168 MMscf/yr) to control Group 2 vent streams that exhibit minimal emissions of HAP and VOC, and we continue to believe this estimate is conservatively high even after revising our cost analysis. For this reason, we are not revising our estimate of secondary impacts (including emissions of CO, CO

                    <P>
                        With regard to the commenters' assertion that many facilities will still be required to comply with TRE-based determinations according to their title V operating permits and requirements under NSPS subparts NNN and RRR, we note that we are simplifying the HON overlap provisions for NSPS subparts III, NNN, and RRR in the final rule (
                        <E T="03">i.e.,</E>
                         we are finalizing, as proposed, that pursuant to 40 CFR 63.110(d)(1), (d)(4), (d)(7), and (d)(10) process vents subject to the emission standards in HON that are also subject to the NSPS subpart III, NNN, and/or RRR are only required to comply with the HON). Also, facilities already have general obligations under title V reopening for cause and 5-year renewals to ensure that permits include all requirements applicable to a facility.
                    </P>
                    <P>Concerning emissions averaging, we note that the provisions experienced no significant changes as a result of removing the TRE concept. The only explicit references to the TRE concept as part of the emissions averaging provisions are at 40 CFR 63.150(g)(2)(iii)(B)(2) with respect to a vent transitioning from a Group 1 process vent to a Group 2 process vent and at 40 CFR 63.150(m)(2)(i) related to obligations associated with carbon absorbers, adsorbers, or condensers not equipped with a control device. Both of these references are captured as no longer being required at 40 CFR 63.113(a)(4)(xii) and 40 CFR 63.113(a)(4)(xiii), respectively, and do not affect applicability. Emissions averaging has always been an optional provision with its burden falling on owners or operators to decide if it was appropriate or cost-effective to over-control certain streams while under-controlling other streams. This does not change as a result of redefining Group 2 process vents to be those streams containing less than 1.0 lb/hr of HAP. In addition, we note that credits may be generated from controlling Group 1 process vents at a higher nominal efficiency than the reference technology and from utilizing pollution prevention measures either independently or in combination with Group 1 process vents as specified at 40 CFR 63.150(c). Thus, even if a facility determines that controlling Group 2 process vents is infeasible, there are other avenues to pursuing the emission averaging provisions.</P>
                    <P>
                        Finally, we disagree with the commenters' suggestion to raise the TRE index value threshold. Regarding a commenter's assertion that removing the TRE concept is flawed given that no action was taken on the TRE concept in the MON RTR, we note that we did not have data related to Group 2 process vents while developing revisions to the MON. Setting an emission threshold with no knowledge as to which Group 2 MON vent streams would be impacted and without knowing the potential cost or reductions associated with that revision would not have been appropriate. Thus, we did not identify any cost-effective developments in practices, processes, or control technologies for process vents. However, as part of this rulemaking, the Group 2 process vent data was collected via a CAA section 114 request. Our analysis of the Group 2 process vent data shows that removing the TRE concept and installing a 1.0 lb/hr of HAP emission threshold is of a similar cost effectiveness to raising the TRE index value to 5.0. However, for the reasons stated earlier in this document, removing the TRE concept was selected. 
                        <PRTPAGE P="42995"/>
                        Given that we determined that a TRE index value of 5.0 was cost effective but opted to remove the TRE concept instead, it would be unreasonable to finalize a TRE index value of 3.0 based on the considerations discussed above and the decreased potential impact.

                         Commenters said they opposed the EPA's proposed rule text at 40 CFR 63.101 and 40 CFR 63.113(a)(1) and (2) that would remove the 50 ppmv and 0.005 scmm Group 1 process vent thresholds from the Group 1 process vent definition and that would instead require owners and operators of process vents that emit greater than or equal to 1.0 lb/hr of total organic HAP to either reduce emissions of organic HAP using a flare meeting the proposed operating and monitoring requirements for flares in NESHAP subpart F or reduce emissions of total organic HAP or TOC by 98 percent by weight or to an exit concentration of 20 ppmv.

                    <P>A commenter requested that the EPA explain how it arrived at a 1 lb/hr control threshold. The commenter said that while the simplicity of a 1 lb/hr threshold is admittedly appealing, it is overly simplistic, and because the EPA did not supply any justification for the choice of 1 lb/hr, it appears to be an arbitrary and capricious threshold value.</P>
                    <P>Another commenter requested that if the EPA decides to keep the proposed Group 1 process vent definition with the 1.0 lb/hr total organic HAP mass flow rate threshold, then these proposed revisions should apply only to new sources in the HON. The commenter asserted that facilities with new sources will have greater flexibility in selecting cost-effective control options during the design and construction phase than the very limited, and climate impacting, options available to retrofit existing sources. The commenter added that additional controls would have virtually no effect on improving ample margin of safety or additional protection of public health.</P>

                         Commenters did not provide sufficient information detailing why requiring the control of process vents that emit greater than 1.0 lb/hr of total organic HAP would be infeasible beyond the arguments related to the removal of the TRE concept which are addressed in response to another comment in this section of this preamble. Consequently, we are finalizing rule text, as proposed at 40 CFR 63.101 and 40 CFR 63.113(a)(1) and (2), that removes the 50 ppmv and 0.005 scmm Group 1 process vent thresholds from the Group 1 process vent definition and instead requires owners and operators to control process vents that emit greater than or equal to 1.0 lb/hr of total organic HAP.
                    </P>
                    <P>We disagree with the commenters' contention that the 1.0 lb/hr of total organic HAP threshold is arbitrary and capricious. As stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), we arrived at the 1.0 lb/hr of total organic HAP threshold using detailed information for 50 Group 2 continuous process vents that was provided by 9 of the 13 HON facilities (including 1 P&amp;R I facility collocated with a HON facility) that received the CAA section 114 request.</P>
                    <P>
                        We started by performing an analysis of the 50 Group 2 continuous process vents for a simple control scenario. Using vent stream flowrates, vent stream net heating values, VOC and HAP emission rates (which we obtained from TRE index value calculations that facilities provided in their response to the CAA section 114 request), and the methodology from the sixth edition of the EPA Air Pollution Control Cost Manual; we calculated a cost for installing ductwork and a blower on each vent, assuming each of these vents could be routed to an existing control device achieving 98 percent by weight emission reduction. Given that many of the Group 2 continuous process vents have a very low flow rate and/or emission rate, we found that even installing simple ductwork and a blower would not be cost-effective for the majority of these vents. However, we did identify 23 of these Group 2 continuous process vents (a subset of the 50 Group 2 process vents from responses to our CAA section 114 request) for which we found this scenario to be cost-effective (
                        <E T="03">i.e.,</E>
                         $1,100 per ton of VOC/HAP or less).
                    </P>
                    <P>
                        We then reviewed mass flow rates of total organic HAP within this subset of Group 2 continuous process vents to develop two different thresholds (
                        <E T="03">i.e.,</E>
                         0.10 lb/hr and 1.0 lb/hr) for consideration. We estimated that 48 HON facilities operating 287 HON Group 2 process vents (96 of which are already voluntarily controlled and 191 that are not currently controlled) and 3 P&amp;R I facilities operating 30 P&amp;R II Group 2 continuous front-end process vents (in which all 30 are not currently controlled) would be impacted if we implemented a 0.10 lb/hr total organic HAP mass flow rate threshold. Conversely, only 16 HON facilities operating 48 HON Group 2 process vents (32 of which are already voluntarily controlled and 16 that are not currently controlled) and 3 P&amp;R I facilities operating 9 P&amp;R I Group 2 continuous front-end process vents (in which all 9 are not currently controlled) would be impacted if we implemented a 1.0 lb/hr total organic HAP mass flow rate threshold. We then estimated costs to control each Group 2 continuous process vent scenario and ultimately concluded that only those streams with greater than or equal to 1.0 lb/hr of total organic HAP would be cost-effective to control. The details of this analysis are discussed in the document titled

                        <E T="03">Comment:</E>
                         Commenters suggested that the EPA significantly underestimated the cost of installing an additional thermal oxidizer and that therefore the cost effectiveness evaluation for removing the TRE concept is not correct. Many of these commenters contended that the fact that a control device has the capability to control multiple process vents does not automatically imply that controlling all vents together is cost-effective in every scenario; if the cumulative emissions from the Group 2 process vents are relatively low, it would not be economically viable to control all of them using a single control device. A commenter said that although it is reasonable to assume that a single new control device will be installed for facilities that will be controlling existing Group 2 process vents with emissions greater than 1.0 lb/hr, the use of 10 scfm for determining a total capital investment (TCI) for the new control device is not representative. The 
                        <PRTPAGE P="42996"/>
                        commenter contended that although these vents are expected to have lower volumetric flow rates than many existing Group 1 vents, there are logistical and safety concerns that must be considered when designing a closed vent system and thermal oxidizer that necessitate higher flow rates. The commenter added that there are multiple facilities with more than one of these types of vents per facility; thus, multiple vents will need to be collected into a common system which will correspond to a higher flow rate. The commenter said that a reasonable low-end estimate for a new single thermal oxidizer for controlling these process vents is closer to a $1,000,000 TCI. The commenter also noted that capital costs could range from $5,000,000 to $15,000,000. The commenter added that for facilities that produce chlorinated compounds, this cost would be higher because any new thermal oxidizer will need to be equipped with acid gas and dioxin/furan controls. Another commenter agreed that facilities that produce chlorinated compounds would incur higher costs but contended that additional controls for a facility's Group 2 process vents would cost at least $50,000,000 in engineering and design, equipment, and installation costs.

                        Another commenter said that for their facility, the addition of a single control device, associated piping, instrumentation, engineering, and installation to control 11 process vents (that are currently considered Group 2 under the HON) will cost $55,000,000, or approximately $925,000/ton of HAPs. Another commenter argued that emission sources that are long distances away from existing control devices (
                        <E T="03">e.g.,</E>
                         a tank in a remote tank farm) and streams not compatible with a facility's existing control equipment are no more economically feasible for additional controls now than when the HON was originally promulgated.

                         $1,000,000 to $55,000,000). However, the commenters did not provide information to fully support these capital costs. For example, commenters did not provide the number of streams nor the flow rate for the new streams needing control, did not provide any related emissions reductions from controlling these streams, and did not provide the annual cost for their scenario. As such, it was not possible to fully evaluate the commenters' provided capital cost data.
                    </P>
                    <P>
                        However, we do agree with commenters that our proposed cost estimate underestimated flow rates needed to route Group 2 continuous process vents with greater than or equal to 1.0 lb/hr of total organic HAP to APCDs. Although we still believe the use of the EPA's control cost template to estimate the cost of installing a new recuperative thermal oxidizer is appropriate (to control a Group 2 continuous process vent with greater than or equal to 1.0 lb/hr of total organic HAP), we revised our estimates to reflect the limitations of the correlations associated with the EPA's control cost template which starts with a flow rate of 500 scfm. With these corrections, we estimate the average TCI to install a new recuperative thermal oxidizer (for both the HON and the P&amp;R I NESHAP) is about $167,000 (as opposed to the $66,000 that we proposed); however, our estimate is still much lower than the wide range of cost estimates provided by commenters. One possible explanation for this difference in cost estimates is that commenters may have used a much higher flow rate (
                        <E T="03">e.g.,</E>
                         5,000 scfm as opposed to 500 scfm) and a “Regenerative Thermal Oxidizer” in their cost analysis instead of a “Recuperative Thermal Oxidizer.” Moreover, commenters did not provide supporting information for their estimated capital costs, so we do not have a way to corroborate this possible explanation.
                    </P>
                    <P>
                        In light of the fact that commenters were generally concerned about the cost estimate, we performed additional analyses to evaluate the cost effectiveness of removing the TRE concept from the HON and the P&amp;R I NESHAP. Using a TCI of $1,000,000 as provided by the commenter, and the EPA's control cost template (for installing a new recuperative thermal oxidizer with 70 percent energy recovery), we estimated an annual cost of approximately $330,000 (for the HON) and $318,000 (for the P&amp;R I NESHAP). Applying this annual cost to our estimated number of HON facilities that would need to install a thermal oxidizer and to our estimated HAP emissions reductions for the HON of 538 tpy, we calculated a cost effectiveness of about $9,830 per ton, which we consider to be cost-effective. Applying this annual cost to our estimated number of P&amp;R I facilities that would need to install a thermal oxidizer and to our estimated HAP emissions reductions for the P&amp;R I NESHAP of 130 tpy, we calculated a cost effectiveness of about $7,440 per ton. It is important to note that our analysis considers that 16 HON facilities operating 48 HON Group 2 process vents (32 of which are already controlled by an existing APCD and 16 that are not currently controlled) and 3 P&amp;R I facilities operating 9 P&amp;R I Group 2 continuous front-end process vents (in which all 9 are not currently controlled) would be impacted by the 1.0 lb/hr total organic HAP mass flow rate threshold. We estimated these impacts using the Group 2 process vent data from responses to our CAA section 114 request. As part of our reevaluation, we also revised our HAP emissions reduction estimate for the HON and P&amp;R I process vents that are not currently controlled to reflect the average HAP emissions reductions from the three HON Group 2 process vents and five P&amp;R I Group 2 process vents that would be impacted by the 1.0 lb/hr total organic HAP mass flow rate threshold (based on data from responses to our CAA section 114 request). In our proposal, we took the lowest HAP emission reduction based on a single HON process vent and did not appropriately account for the other HON process vents for which we had data. We corrected a similar issue for the P&amp;R I NESHAP. Therefore, our final calculation for estimating the cost effectiveness for removing the TRE concept in its entirety from the HON includes a total HAP and VOC reduction of 538 tpy (and not 436 tpy as proposed) and for the P&amp;R I NESHAP, a total HAP and VOC reduction of 130 tpy (and not 51 tpy as proposed). It is also possible that the actual emissions reductions may be higher than our estimate because the higher capital costs provided by industry are likely to be for thermal oxidizers that are sized to control higher flow streams with more HAP emissions.

                        Absent additional detailed information from commenters, we are finalizing the removal of the TRE concept as proposed and are requiring control for process vents that emit greater than or equal to 1.0 lb/hr of total organic HAP. We also believe this is 
                        <PRTPAGE P="42997"/>
                        reasonable given that a 1.0 lb/hr total organic HAP mass flow rate threshold for continuous HON and P&amp;R I process vents aligns more closely with the batch process vent control threshold in the MON and the NESHAP for Chemical Manufacturing Area Sources. In each of these NESHAP, the applicability threshold of 10,000 lb/yr per process is used for batch process vents.

                         Commenters observed that the EPA's favorable cost-effectiveness outcome is based on emissions reductions that have already occurred and that will not occur as a result of the proposed standards (and thus should not be used in the calculus). The commenters remarked that the EPA's final calculation for estimating the cost effectiveness for removing the TRE concept in its entirety included a total annual cost of $3,150,000 and a HAP and VOC reduction of 436 tpy. The commenters pointed out that process vents that are already voluntarily controlled account for 366 tpy of the total reduction even though they will not have emissions reductions as a result of implementing the new proposed definition of a Group 1 process vent. The commenters argued that if the EPA determines that the emissions reductions from these vents should be included in the analysis, the Agency must account for the entire cost associated with controlling these emissions (
                        <E T="03">i.e.,</E>
                         annual costs associated with operating a thermal oxidizer) rather than only the costs associated with the installation and operation of ductwork and blowers. The commenters added that if there are no emissions reductions expected from process vents that are already voluntarily controlled, then the cost effectiveness analysis should be revised such that it does not include reductions from these vents.

                         The EPA maintains that the emission reductions associated with removing the TRE concept and redefining Group 1 process vents to include process vents emitting greater than 1.0 lb/hr of HAP are reasonable, and the EPA is not making any revisions as a result of this comment. Commenters are correct in stating that 366 tpy of HAP emitted by HON process vents exceeding 1.0 lb/hr of HAP are already voluntarily controlled. However, the emission reductions are presented on a basis of allowable emissions. Previously, there were no requirements for process vents exceeding 1.0 lb/hr of HAP. Therefore, under the previous rulemaking, all emissions from these vents were allowable, regardless of whether some facilities were voluntarily controlling these emissions or not. By setting the emission threshold of 1.0 lb/hr of HAP, the allowable emissions are restricted, resulting in the 366 tpy of emission reductions that the EPA utilized to determine the cost effectiveness of removing the TRE concept and redefining Group 1 process vents. We note that we updated our total HAP reductions and annual cost estimates in response to a comment reflected elsewhere in this section of this preamble. For details on how we revised our estimate of cost and HAP emissions reductions, see the document titled

                        We also disagree with commenters that annual operating costs should be considered for the control devices that are controlling the voluntarily controlled streams. These existing control devices are controlling other streams that are regulated (

                         Commenters requested that the EPA add EPA Method 320 to 40 CFR 63.115(g)(2) and (3) and allow companies to use measurements or testing conducted within the last 5 years to initially demonstrate that a process vent is a Group 2 process vent under 40 CFR 63.115(g) provided that: (1) The prior measurement or test was conducted using the same methods specified in 40 CFR 63.115(g), and (2) either no process changes have been made since the test, or the owner or operator can demonstrate that the results of the measurement or test, with or without adjustments, reliably demonstrate compliance with 40 CFR 63.115(a) despite process changes.
                    </P>
                    <P>A commenter also requested that the EPA allow companies to use engineering calculations or process knowledge to initially demonstrate that a process vent is a Group 2 process vent under 40 CFR 63.115(g). The commenter pointed out that they already conducted testing and sampling procedures on their emission points corresponding to the EPA's CAA section 114 request which cost $20,000 to $30,000 for a single process vent. The commenter added that testing every vent stream is not necessary where an owner or operator has engineering calculations or process knowledge to demonstrate that a vent stream is a Group 2 process vent; and historically, under the group determination procedures for process vents, the owner or operator of a Group 2 process vent with a TRE index value greater than 4.0 could use measurements, engineering assessments, and calculations to determine the TRE index value of the vent stream. The commenter also said that one of their facilities continuously monitors vent flow and HAP concentration from two HON process vents when they are routed to atmosphere and uses the calculated TRE index value to demonstrate that the vents remain Group 2 on an ongoing basis. The commenter said that this alternative monitoring approach was requested and approved due to the variability of HAP emissions from those vents; and generally, the calculated TRE index value remains well above 5.0. The commenter claimed that this alternative monitoring is used when the site thermal oxidizer is down for preventive maintenance; and meeting the proposed new process vent requirements would require either a significant investment in new control equipment or shutdown of the process during thermal oxidizer maintenance.</P>

                         We are revising the final rule based on the commenter's request to add EPA Method 320 to 40 CFR 63.115(g)(2) and (3) and allow for certain previously conducted performance tests to be exempt from the Group 2 demonstration requirements at 40 CFR 63.115(g) provided the owner or operator can demonstrate: (1) No changes have been made to the process since the time of the previously conducted measurement or emission test; (2) the previously conducted measurement or emission test was conducted using the same methods specified in 40 CFR 63.115(g); and (3) the previously conducted measurement or emission test was completed within the last 60 months. However, we disagree with the commenters' request to allow companies to use engineering calculations or process knowledge to initially demonstrate that a process vent is a Group 2 process vent under 40 CFR 63.115(g). As with our concerns relative to the TRE index value, the ability to use assessments leads to greater uncertainty with regard to characterization of vent streams and their emission potential. We note that as explained in section IV.C.3.e of this preamble, we are finalizing language in the “C” and “Q” terms of the equations

                         Numerous commenters supported the EPA's proposal to require fenceline monitoring at facilities in the SOCMI and P&amp;R I source categories that use, produce, store, or emit benzene, 1,3-butadiene, chloroprene, EtO, ethylene dichloride, or vinyl chloride. These commenters also said they support the requirement to conduct root cause analysis and corrective action. In addition, some commenters voiced their support for requiring monitoring data to be made available to the public in the WebFIRE database, allowing communities to have access to information that impacts them. Some commenters said the fenceline monitoring technology has proven to be a valuable tool for petroleum refineries to timely detect problems and to address them more quickly, substantially reducing emissions from leaks and other fugitives. At least one commenter said fenceline monitoring can provide numerous benefits, including assisting in identifying an accidental release, and in the event of an accidental release, give the community immediate notice of the emergency and any necessary mitigation responses they should employ (shelter in place, close windows, evacuate, 
                        <E T="03">etc.</E>
                        ). This commenter added that fenceline monitoring can also: help communities advocate for vigorous enforcement of regulatory requirements; push companies to use safer chemicals; alert and educate friends, family members, and community members; and encourage the media to report on polluting facilities in their areas. The commenter also suggested that facilities can use fenceline monitoring data to take the initiative to improve safety at their operations. Other commenters requested that EtO emissions be required to be monitored by third-party companies. The commenters explained that current laws in some states allow facilities to monitor their own emissions, which could cause underreported emissions.

                        A commenter argued that fenceline monitoring requirements are crucial in protecting the communities referred to by the commenter as Cancer Alley, especially in St. John the Baptist Parish, which the commenter claimed has the highest cancer rates in the country. The commenter stated that more and more residents are either facing a cancer diagnosis or know someone, such as an immediate family, diagnosed with cancer; and asthma rates and hospitalizations from asthma are ever-increasing, especially amongst children. The commenter also said the area is facing increased weather events brought about by climate change. Citing an analysis by the

                         newspapers, the commenter said that 740 toxic sites are at risk from storms, with most of those plants concentrated in the area the commenters refer to as Cancer Alley. The commenter said that after experiencing numerous storms, they personally witnessed the flaring of surrounding plants, including the plants that produce EtO, and are concerned about the increase of pollution before, during, and after weather events.

These commenters primarily argued that the EPA exceeded its authority under CAA section 112(d)(6) because fenceline monitoring is not a “development[] in practices, processes, and control technologies” for fugitive EtO emissions. Commenters in opposition of fenceline monitoring made the following points about the EPA's assertion of authority to require fenceline monitoring:</P>

                         see Docket Item No. EPA-HQ-OAR-2018-0746-0200) that they were “not aware of any methodology or technology with the necessary accuracy, precision, and detection sensitivity to require fenceline monitoring for EtO.”

                    <P>• The EPA does not explain how fenceline monitoring, which by itself does not reduce emissions, is a development.</P>

                    <P>• According to the proposed rule, at least in places, fenceline monitoring (coupled with root cause analysis and corrective action) is a work practice standard “that is a development in practices considered under CAA section 112(d)(6) for the purposes of managing fugitive emissions”; however, the EPA considered two monitoring methods—not action levels, root cause analysis, or corrective action—as developments in practices, and it is unclear how monitoring methods fall under any other of the broad categories of developments previously defined by the EPA.</P>
                    <P>• If the root cause analysis and the corrective action requirements are the work practice standards—as the EPA stated in the proposed NESHAP for EtO commercial sterilization and fumigation operations—then how are monitoring methods a work practice standard?

                    <P>
                        • Adding data quality requirements and existing best practices does not render EPA Method 327 a new development, nor does it remedy the concerns about facilities' ability to accurately measure fenceline EtO concentrations (

                         there are still no reliable methods that can measure to the level of precision required).

                    <P>• Coupling fenceline monitoring with a canister monitoring network and a so-called “new” reference method does not transform the fenceline monitoring as proposed into a new technology that is within the CAA section 112(d)(6) authority.</P>
                    <P>
                        Some of these commenters contended that even if the proposed fenceline monitoring requirements were within the scope of CAA section 112(d)(6) authority, the EPA failed to adequately consider/quantify a level of emission reduction from the proposed fenceline monitoring and did not account for any of the potential costs associated with achieving such emission reductions (
                        <E T="03">i.e.,</E>
                         the EPA only considered the costs of the actual monitoring and not the root cause and corrective action requirements). A commenter asserted that had the EPA appropriately accounted for costs, it would have concluded that the proposed fenceline monitoring requirements are not cost-effective, consistent with the Agency's determination for the options 
                        <PRTPAGE P="42999"/>
                        considered for equipment leaks, PRDs, and storage vessel breathing losses. The commenter argued that the EPA failed to quantify the additional HAP emissions reductions for EtO and chloroprene that the Agency indicates will be required for compliance or to consider the cost of these additional reductions (in addition to the cost of the required root cause and corrective action analyses) as is required to meet the Agency's obligation under CAA section 112(d)(2). The commenter stated that the EPA has not assigned emissions reductions of benzene, 1,3-butadiene, ethylene dichloride, or vinyl chloride as a result of implementing the proposed fenceline monitoring work practice requirements; and with the exception of EtO and chloroprene, the Agency implies that additional reductions beyond those the EPA proposed elsewhere in the rulemaking will be unnecessary to meet the fenceline action levels. The commenter attested that the EPA proposed additional requirements on top of those already required by the existing rules, or that will be required as part of the other proposed revisions (
                        <E T="03">e.g.,</E>
                         the proposed flare standards, the existing and proposed monitoring requirements for process vents, and equipment leaks and PRDs), without identifying deficiencies in the current and proposed requirements. Similarly, other commenters stated that the EPA has not demonstrated that fenceline monitoring is necessary to reduce HAP emissions or to provide an ample margin of safety; and the lack of emissions reductions associated with the proposed requirements shows that such requirements are unnecessary to the ultimate goals of CAA section 112.

                        <E T="03">Response:</E>
                         We disagree with the commenters' assertion that the proposed fenceline monitoring work practice standard is not authorized under CAA section 112(d)(6), but we are making certain changes to the fenceline monitoring program in the final rule in response to comments, including adopting a second action level for just chloroprene under CAA section 112(f)(2). Contrary to the commenter's claims, we specifically proposed the fenceline monitoring standard under CAA section 112(d)(6) to be a work practice standard that is applied broadly to target fugitive emissions sources located at HON and P&amp;R I facilities. The proposed standard does more than impose monitoring as some commenters suggested; it also limits emissions from sources because it requires the owner or operator to identify and reduce HAP emissions through a monitoring and repair program, as do many work practice standards authorized under CAA sections 112(h) and (d). We note that the sources addressed by the fenceline monitoring standard—fugitive emissions sources such as wastewater collection and treatment operations, equipment leaks, heat exchange systems and storage vessels—are already subject to work practice standards. Our review of these requirements indicates that this fenceline monitoring work practice standard would be a further improvement in the way fugitive emissions are managed and would, by providing such further assurance of compliance with emission standards and work practice standards, also provide an extra measure of protection for surrounding communities. Consistent with the criteria in CAA section 112(h)(2), we determined and established that work practice standards are appropriate for fugitive emissions at the time we established the initial MACT standards. Today, we reaffirm that it is impracticable to directly measure all fugitive emission sources at a given source but do not consider it necessary to reiterate these findings as part of this action to add the fenceline monitoring provisions for these sources under CAA sections 112(d)(6) and (f)(2). We note that the commenters do not provide any grounds to support a reevaluation as to whether these fugitive emission sources are appropriately regulated by a work practice standard.

                    <P>
                        The EPA, in establishing action levels for the fenceline monitoring work practice standard, relied on the authority provided in CAA section 112(d)(6) to set action levels at the highest concentration anticipated, considering the emission reductions anticipated under the additional standards we are adopting under CAA sections 112(d)(6) and 112(f)(2). Again, the section 112(d)(6)-based action levels function to verify the expected emissions reductions resulting from compliance with the final emission standards, and reflect concentration levels that are largely already resulting from sources subject to the rules and are therefore cost-effective. Further, in the proposal the EPA acknowledged that the proposed action levels for EtO and chloroprene of 0.2 ug/m
                        <E T="51">3</E>
                         and 0.3 ug/m
                        <E T="51">3</E>
                        , respectively, were lower than the fenceline modeled concentrations for EtO and chloroprene from facilities in the SOCMI and Neoprene Production source categories after implementation of the proposed emission standards, and we took comment on whether we should require these lower action levels under CAA section 112(f)(2). In this final rule, we believe it is reasonable, given the unique circumstances presented by these source categories, to require these lower action levels. First, for EtO, the lower action level reflects concentrations that all HON-subject facilities, except for one, are currently meeting and are therefore cost-effective under CAA section 112(d)(6). Second, consistent with the second step of the risk review under the Benzene NESHAP approach addressing whole-facility risks, for chloroprene the lower action level reflects concentrations what will result in whole facility risks from this HAP dropping to 100-in-1 million. Further whole-facility reductions in EtO and chloroprene emissions from other sources located at major source facilities subject to these standards, including sources outside the source category, will help reduce risks from the whole-facility emissions of EtO and chloroprene from facilities with sources in the SOCMI and Neoprene Production source categories.

                    <P>
                        To reduce risk in the final rule we are making an adjustment from what was proposed. First, we are establishing under CAA section 112(d)(6), for all six of the monitored pollutants, action levels that correspond to the fenceline concentrations expected to result from compliance with the final rule's standards and work practices applicable to HON and P&amp;R I processes and which reflect concentrations that HON and P&amp;R I sources are largely already achieving, such that these action levels function to provide further assurance of such compliance of the emission standards and provide for corrective action when action levels are exceeded. For benzene, 1,3-butadiene, ethylene dichloride, EtO and vinyl chloride, these are the same action levels as proposed. For chloroprene, instead, the action level has been adjusted upward to 0.8 ug/m
                        <E T="51">3</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0091, page 24) to reflect the modeled expected fenceline concentration resulting from the other final standards and work practices chloroprene. This first action level is, therefore, consistent with how we established fenceline monitoring requirements under CAA section 112(d)(6) in the petroleum refineries NESHAP and how we represent the primary CAA section 112(d)(6)-based fenceline monitoring program under the final rule.
                    </P>
                    <P>
                        Although the EtO action level of 0.2 ug/m
                        <E T="51">3</E>
                         is lower than what the EPA's modeling shows will result from compliance with the final CAA section 112(d) and 112(f) SOCMI source category emission standards in the final HON, as we discussed in the proposed rule, we expect that major sources with 
                        <PRTPAGE P="43000"/>
                        HON processes will be able to employ additional facility-wide measures, including those at other EtO-emitting processes outside of the SOCMI source category, to obtain additional cost-effective EtO reductions via improvements in maintenance and operations and enable compliance with the CAA section 112(d)(6) EtO action level. This is already being demonstrated by the fact that all HON-subject facilities, except for one, are already showing concentrations at or below the final action level. Moreover, this is reasonable due to the integrated nature of chemical plant operations, where multiple process units may be subject to NESHAP for more than one source category and products of units in some categories may also be feedstocks for units in other source categories. Accordingly, the source category designations, while part of the NESHAP program, are somewhat of an artificial distinction in these highly integrated chemical manufacturing facilities. For example, there are emission sources that often serve the entire facility, such as wastewater treatment systems and heat exchange systems, but they are typically assigned to a single source category or subcategory. Because of the propensity for large integrated chemical plants to contain numerous source categories, and also to contain units that span multiple source categories, we are finalizing fenceline work practice standards with an EtO action level that relies on achieving reductions across the whole HON facility, even if that includes non-HON EtO-emitting processes.
                    </P>
                    <P>Second, in light of the very high risk presented by chloroprene emissions, we have concluded it is appropriate, in addition to adopting the primary CAA section 112(d)(6)-based action levels and monitoring program for all six subject HAP, to supplement the program with a secondary action level for this pollutant. This secondary action level, equivalent to that proposed, reflects fenceline concentrations for this pollutant that increase the margin of safety and advances the objectives of CAA section 112(f)(2). Although our modeling indicates that compliance with the other emission standards and work practices promulgated for Neoprene Production sources may not produce this secondary level, we anticipate—as explained in the proposal—that major sources will be able to employ additional facility-wide measures, such as maintenance measures, to achieve further chloroprene reductions to reach this secondary, CAA section 112(f)-based action level.</P>
                    <P>
                        In the case of chloroprene emitted by the Denka Performance Elastomer, LLC facility (subject to both the P&amp;R I NESHAP and the HON), we do not anticipate taking further source-category-wide rulemaking action that could re-set CAA section 112(d)(6)-based lower action levels to reflect future additional chloroprene reductions from additional source category processes. Consequently, for Denka Performance Elastomer, LLC's chloroprene emissions, this rulemaking is the final opportunity for us to establish an action level with the goal of assuring that whole-facility chloroprene emissions are reduced to a level that provides an ample margin of safety to protect public health.

                         This is consistent with the statute because under the CAA section 112(f)(2) ample margin of safety second step, the Benzene NESHAP approach that is incorporated into the CAA allows the EPA to consider quantified or unquantified health effects, effects due to co-location of facilities, and co-emission of pollutants.

                    <P>We disagree that the fenceline monitoring standards we are finalizing in this rule are redundant with MACT emissions standards for fugitive HAP emissions sources. The MACT standards impose requirements on fugitive HAP emissions sources consistent with the requirements in CAA section 112(d)(2) and (3), and the fenceline monitoring requirement is not a replacement for those requirements. Rather, based on our review of these standards, we concluded that the primary CAA section 112(d)(6)-based fenceline monitoring program is a development in practices, processes or control technologies that is a necessary revision to the previous standard, as it would improve management of fugitive emissions in a cost-effective manner and help assure compliance with applicable process emission standards under the HON and the P&amp;R I NESHAP. Requiring sources to establish a fenceline monitoring program that identifies HAP emission sources that cause elevated pollutant concentrations at the fenceline, and correcting high emissions through a more focused effort, augments but does not replace the existing requirements. We found that, through early identification of significant fugitive HAP releases through fenceline monitoring, compliance with the Refinery MACT fenceline work practice standard for these similar emissions sources in these source categories has resulted in a significant reduction in benzene emissions. The action levels for the primary fenceline work practice standard, by contrast, are not based on the best performers but rather on the highest value expected on the fenceline from any source, based largely on the modeling of emission inventories expected to result from compliance with the final emission standards and work practices under the rules.</P>
                    <P>Lastly, we acknowledge commenters' support for fenceline monitoring. However, with respect to the commenter requesting that a third party be required to monitor the fenceline concentrations, the EPA disagrees. Fenceline monitoring requires a level of access to the facility and measurement devices that would be burdensome to accommodate for facilities. Fenceline monitoring is intended to address concerns with underreported emission inventories and works based on timely root cause analysis. Adding a third-party requirement would slow a facility's ability to respond to fugitive emissions in a timely manner.</P>

                        <E T="03">Comment:</E>
                         A commenter argued that fenceline monitoring is not an emissions standard or work practice within the meaning of CAA section 112. Citing CAA section 302(k), the commenter said that, by itself, fenceline monitoring does not reduce emissions, rather all that fenceline monitoring does is identify ambient concentrations of a specific chemical; it does not even identify whether the chemical is from a regulated source, let alone identify a specific regulated unit at such source. The commenter said that fenceline monitoring can only potentially reduce emissions when coupled with additional requirements, but, at least in this instance, the EPA does not appear to claim associated reductions from the source category. The commenter added that while the EPA is proposing “action levels,” again, these levels alone do not “limit the quantity, rate, or concentration of emissions.” The commenter said that according to the preamble, if the emissions inventories are accurate, “all facilities should be able to meet the fenceline concentration action levels considering the controls [EPA is] proposing”; therefore, even when coupled with action levels, the EPA's proposal does not claim that fenceline monitoring will result in any meaningful emissions reductions from the source category. The commenter also stated that while exceedance of an action level may trigger further requirements, the action level does not, by itself or combined with fenceline monitoring, limit emissions—additional actions are required; and, because the 
                        <PRTPAGE P="43001"/>
                        EPA's proposal measures ambient concentrations, an exceedance of a proposed action level is not necessarily the result of emissions from the facility in question or from an exceedance of a standard.
                    </P>
                    <P>The commenter noted that while the EPA states that it is proposing fenceline monitoring as a work practice standard, which could fall within the meaning of “any design, equipment, work practice or operational standard promulgated under [the CAA],” the EPA does not explain how fenceline monitoring meets the requirements for a work practice standard. The commenter added that work practice standards are authorized only in limited circumstances under CAA section 112(h)(1) when it is not feasible to prescribe or enforce an emission standard for control of HAPs, and the EPA has not adequately explained what elements of the proposal are work practice standards.</P>

                         Section 112(d)(6) of the CAA requires the EPA to review and revise the MACT standards, as necessary, taking into account developments in “practices, processes and control technologies.” Consistent with our long standing practice for the technology review of MACT standards, in section II.G.1 of the proposal preamble, we list five types of “developments” we consider.
                    </P>
                    <P>Fenceline monitoring fits squarely within two of those five types of developments (emphasis added):</P>
                    <P>
                        • Any add-on control technology or

                         that was not identified and considered during development of the original MACT standards.

                    <P>
                        • Any

                         or operational procedure that was not identified or considered during development of the original MACT standards.

                    <P>
                        As used here, “other equipment” is clearly separate from and in addition to “add-on control” technology and is broad enough to include monitoring equipment. In this case, fenceline monitoring includes equipment that we did not identify and consider during development of the original MACT standards. Additionally, the primary fenceline standard is a work practice standard, involving monitoring, root cause analysis, and corrective action not identified at the time of the original MACT standards. Therefore, the primary fenceline requirements are a development in practices that will improve how facilities manage fugitive emissions, and the EPA appropriately relied on CAA section 112(d)(6) in requiring this standard. (Note: The EPA is not relying on CAA section 112(f)(2) as the basis for the primary fenceline monitoring work practice standard established under section 112(d)(6) for benzene, butadiene, vinyl chloride, ethylene dichloride, chloroprene, and EtO, and has set action levels according to the annual average concentrations modeled at the facility fenceline for any facility after compliance with process unit emission standards applicable to HON and P&amp;R I sources and that reflect levels sources are largely already achieving. However, as discussed elsewhere in this section of the preamble, we are also setting a secondary action level of 0.3 ug/m

                         for chloroprene under CAA section 112(f)(2), because this standard will further reduce risks from the whole-facilities consistent with the goal to provide an ample margin of safety to protect public health).

                         A commenter argued that the EPA's explanation for the basis of selecting the six compounds for fenceline monitoring is inadequate when compared against the rulemaking record. The commenter said that the EPA appears to base its selection of compounds on previous and current risk drivers because the EPA indicates that “[s]everal of these compounds were identified as cancer risk drivers in the prior risk and technology reviews for the HON and P&amp;R I NESHAP conducted in 2006 (HON) and 2008 and 2011 (P&amp;R I). . ..” The commenter contended that, with the exception of EtO, the maximum risk previously found by the EPA in its reviews for the HON and P&amp;R I NESHAP were well below 100-in-1 million (or not identified as a risk driver at all); the commenter provided a table showing the EPA's determinations of 2006 HON, 2008 P&amp;R I and 2011 P&amp;R I MIR for benzene, 1,3-butadiene, chloroprene, EtO, ethylene dichloride, and vinyl chloride. The commenter pointed out that in each of these previous assessments, the EPA found risks acceptable and did not adopt additional standards to address residual risk or to ensure an ample margin of safety. The commenter said the EPA also did not identify benzene, 1,3-butadiene, ethylene dichloride, or vinyl chloride as driving unacceptable risk under the current assessment; thus, while the EPA's selection of benzene, 1,3-butadiene, ethylene dichloride, and vinyl chloride based on risk is questionable under the EPA's framing of the option as part of its CAA section 112(d)(6) technology review, a closer inspection of the EPA's previous risk assessments indicates that in fact, these compounds did not drive any unacceptable risk. The commenter stated that the EPA's proposal to require millions of dollars of monitoring for no emissions reductions is unjustified under CAA section 112(d)(6) and unnecessary under CAA section 112(f). The commenter added that they acknowledge that the EPA found EtO and chloroprene to be risk drivers as part of their voluntary assessment supporting this proposed rulemaking and are claiming unquantified emissions reductions as a result of implementing fenceline monitoring; however, according to the commenter, the Agency determined that these additional reductions are unnecessary under CAA section 112(f) when it proposed to find acceptable risk and an ample margin of safety after implementation of the controls detailed in section III.B.2.a of the proposal preamble (88 FR 25080, April 25, 2023).
                    </P>
                    <P>The commenter argued that it would be inappropriate to consider fenceline monitoring in context of the CAA section 112(f) review. The commenter stated that the EPA has already concluded that the controls that it has proposed to impose protect human health and the environment with an ample margin of safety. The commenter added that the EPA has not identified any additional emission reductions from the source category that would be necessary to reduce risk from the source category and that the EPA has failed to demonstrate that any such controls are cost-effective, which would be included as any ample of safety analysis. The commenter also said that the action level is not tied in a meaningful way to reducing risk to an acceptable level.</P>

                         The EPA implemented a fenceline monitoring standard to address emissions of pollutants that it determined could cause unacceptable risk, based on risk modeling of emission inventories and accounting for the range of uncertainty associated with these estimates. When the EPA promulgated the Refinery MACT fenceline work practice standard, the EPA acknowledged that emissions of benzene and indeed, of all other HAP in the source category, did not pose unacceptable risk when emissions from refineries were modeled, but that the work practice standard was put in place to address the uncertainty associated with emission estimates from fugitive sources and to preserve the decisions regarding the findings of acceptable risk and ample margin of safety (79 FR 36290, June 30, 2014). The same uncertainty exists here for the SOCMI and P&amp;R I source categories. As explained in the April 25, 2023 proposal, we collected fenceline measurements in addition to modeling inventories, and our fenceline measurements indicate that 
                        <PRTPAGE P="43002"/>
                        concentrations at the fenceline almost always exceed modeled concentrations, indicating the potential for significant uncertainty with regard to our risk analysis and findings of acceptable risk. As discussed earlier in this document, the EPA is not relying on CAA section 112(f)(2) as the basis for the primary fenceline monitoring work practice standard established under CAA section 112(d)(6) for benzene, butadiene, vinyl chloride, ethylene dichloride, chloroprene, and EtO and has set action levels according to the annual average concentrations modeled at the facility fenceline for any facility after compliance with process unit emission standards applicable to HON and P&amp;R I sources and that are reflective of concentrations subject sources are already achieving. Further, we disagree with the commenters who suggest that the EPA may not require fenceline monitoring pursuant to CAA section 112(d)(6) because the EPA has not determined that fenceline monitoring is necessary to ensure an acceptable level of risk or to provide an ample margin of safety. CAA section 112(d)(6) does not require the EPA to factor in the health considerations provided in CAA section 112(f)(2) when making a determination whether it is “necessary” to revise the previous emission standard.

                        For chloroprene, we are finalizing in the primary CAA section 112(d)(6)-based program the action level of 0.8 ug/m
                        <SU>3</SU>
                         that reflects compliance with the source category-specific emissions limits for the Neoprene Production source category in the P&amp;R I NESHAP. Separately, we are also setting a secondary action level of 0.3 ug/m
                        <SU>3</SU>
                         for chloroprene under CAA section 112(f)(2), because this standard further reduces from the whole-facility risk from sources emitting chloroprene to levels that are consistent with the goals of CAA section 112(f)(2). As discussed earlier, in the proposal, we acknowledged that the proposed action level of 0.3 ug/m
                        <SU>3</SU>
                         for chloroprene is lower than the fenceline modeled concentrations from facilities in the Neoprene Production source category after implementation of our proposed standards under CAA section 112(f)(2); however, considering whole-facility risks, and in light of the configuration of the emission sources subject to these rules that contribute to whole-facility risk that remain for the impacted communities after the imposition of controls, we are setting the additional second action level for chloroprene at facility boundaries as low as possible (considering method detection limitations) to ensure that the emission reductions anticipated from implementation of controls used to meet the proposed standards and to achieve additional chloroprene emission reductions are achievable. Reductions to achieve this action level will likely come from controlling additional emission sources at the one Neoprene Production facility that might not be considered part of the source category. Controlling these sources reduces emissions from the entire facility, not just the source category, and makes it possible for operators to achieve the lower action level. Thus, in this final rule, and based on the unique circumstances presented here, we consider facility-wide risk as an additional factor we may consider under CAA section 112(f)(2) and, in addition to the primary CAA section 112(d)(6)-based fenceline monitoring program addressing all six subject HAP, we are promulgating a separate and secondary lower action levels for just chloroprene under CAA section 112(f)(2).

                         Many commenters requested that the EPA expand the fenceline monitoring requirements to every facility in the SOCMI, P&amp;R I, and P&amp;R II source categories so owners and operators of these facilities can demonstrate, by representative monitoring data, that pollution from these facilities poses minimal levels of harm to fenceline communities. Some of these commenters pointed out that, as proposed, only about 60 percent of the facilities in these source categories would have to conduct fenceline monitoring. Other commenters contended that, as proposed, 90 facilities would have no fenceline monitoring requirements. A commenter contended that there is no reason or need for the EPA to have selected just six toxic pollutants and used them as basis to omit facilities from fenceline monitoring, given that CAA section 112(d)(6) requires making any changes that are “necessary” to bring standards into full compliance with the CAA, such as setting limits on uncontrolled and inadequately controlled emissions. The commenter pointed out that the EPA set fenceline monitoring requirements that applied to all refineries subject to NESHAP subpart CC and did not omit sources based on the selected constituents to be monitored.
                    </P>
                    <P>
                        Some commenters suggested that the EPA could add more toxic pollutants to its current list of six fenceline monitoring constituents, in order to ensure that each facility has at least one or more sentinel chemicals that can be monitored. A commenter recommended that the EPA include benzene, toluene, ethylbenzene, and xylenes (BTEX), methanol, and formaldehyde constituents to the list of pollutants requiring fenceline monitoring. The commenter pointed out that based on TRI data, the inclusion of formaldehyde to the list of pollutants requiring fenceline monitoring would add another 28 facilities, the inclusion of methanol would add another 13 facilities, and the inclusion of BTEX/n-hexane would add another 3 facilities. The commenter also pointed out that it is no surprise that information gathered from only HON and P&amp;R I sources resulted in constituents most representative of those sources and not representative of P&amp;R II sources; and had the EPA included P&amp;R II data in the information it gathered for the purpose of fenceline monitoring constituents, the EPA would have found that all five P&amp;R II sources emit epichlorohydrin and that several of them emit the non-benzene BTEX constituents. Commenters requested that the EPA add formaldehyde to the list of pollutants requiring fenceline monitoring because the IRIS data indicates that as a carcinogen, formaldehyde is even more potent than benzene. A commenter said evidence from emission reports suggests that some facilities may be underreporting or only sporadically reporting formaldehyde emissions (
                        <E T="03">e.g.,</E>
                         the Conoco-Phillips/Shell Wood River manufacturing site in Illinois reported very large formaldehyde emissions to the NEI in 2017 and even larger amounts to the 2020 NEI but has not disclosed formaldehyde emissions in any of the TRI reports for the facility for the 5 years between 2017 and 2020). A commenter recommended that the EPA require each facility to select the constituents to be monitored via tailored fenceline monitoring plans that are specific to each facility's emissions and risk drivers. Additionally, at least one commenter said they hope that EPA will replicate this multi-pollutant monitoring in other rules, including as a supplement to the ethylene production rules.

                        On the contrary, some commenters argued that the proposed fenceline monitoring requirements would impermissibly regulate emissions from non-HON sources. Citing the proposal at 88 FR 25145-46, some of these commenters pointed out that the EPA expressly notes that facilities are not permitted to exclude non-HON sources of the target pollutants that are within facility property boundaries when determining whether monitored concentrations exceed action levels. The commenters said that regulating emissions from sources outside of the 
                        <PRTPAGE P="43003"/>
                        source category is incompatible with the EPA's statutory mandate to “review and revise” the “emissions standards promulgated under this section,” which refers to the source-category MACT standards promulgated under CAA section 112(d). The commenters stated that the EPA may only regulate HON sources under its technology review authority in accordance with the statutory language and structure of the CAA. The commenters reiterated that when enacting CAA section 112, Congress instructed the EPA to promulgate a list of specific source categories and that Congress then instructed the EPA to establish emission standards “[f]or the categories and subcategories the Administrator lists under subsection (d)” of CAA section 112. At least one of these commenters cited CAA sections 112(c), (d)(1), (d)(3)(A), (d)(6), and (f) as examples of how the CAA authorizes the EPA to impose emissions standards only on particular source categories or subcategories. The commenter asserted that none of these provisions expressly authorize or reasonably can be construed to allow the EPA to develop and impose an emissions standard that applies across multiple source categories. The commenter contended that for this reason, the EPA's proposal to apply fenceline monitoring to site-wide emissions, including emissions from source categories beyond the SOCMI source categories addressed in this rulemaking, is legally unfounded; and if the EPA decides to impose a fenceline monitoring program in the final rule, it must be limited such that it applies only to emissions from particular source categories. Other commenters said they were concerned that the proposed approach results in the EPA's establishing the emission point as the facility boundary, thereby expanding the definition of an affected source. The commenters provided an example saying that the proposed rule does not contain provisions that would exclude a site from fenceline monitoring for benzene due to the presence of a gasoline storage tank onsite that is used to refuel mobile equipment and is not even part of the HON process.
                    </P>
                    <P>Some of the commenters stated that the imposition of fenceline monitoring requirements to non-HON sources is unreasonable, arbitrary, and capricious. One of these commenters said the EPA is conducting the technology review for the SOCMI category and not for other collocated categories; and despite this, the EPA is using this action as a vehicle to impose requirements on other source categories through the HON rather than evaluating such controls in the context of the applicable CAA section 112 standard. The commenter asserted that such use of a source-specific technology review to promulgate requirements that affect an unknown number of other source categories is arbitrary and capricious and circumvents statutory design. The commenter added that the EPA has not assessed the cost that would fall on other source categories and that the EPA's proposal failed to properly provide notice or provide a meaningful opportunity to comment to all interested stakeholders.</P>
                    <P>Some commenters said that they support the EPA's proposal to allow facilities to account for offsite, upwind sources through the use of near-field source correction under 40 CFR 63.184(g); however, these commenters said they disagree with the EPA's assertion that this option should not be provided for onsite, non-source category emissions. These commenters asserted that the EPA cannot regulate sources beyond those subject to the technology review; thus, the commenters said, the EPA should add provisions in the final rule similar to those at 40 CFR 63.658(i) from the 2015 Petroleum Refinery Sector Rule to address onsite sources that are not part of the affected source under the HON and P&amp;R I NESHAP. However, at least one commenter objected to adding provisions in the final rule similar to those at 40 CFR 63.658(i) and stated that inclusion of facility-wide emissions in the action level is appropriate because it will support the control of toxic air pollutants emitted from all sources within the facility, all of which affect fenceline communities, and also avoids the development of complex and uncertain processes to attribute emissions from collocated sources and equipment that may be used in processes associated with multiple source categories. This commenter pointed out that only a small number of refineries (13) have approved site-specific monitoring plans, and only five of those plans include procedures for excluding onsite sources owned by the refinery but that do not fall within the refinery source category.</P>

                        Another commenter provided a real-life example of the difficulty of dealing with onsite, non-source category emissions where Facility A, which is subject to the HON, owns and operates an Industrial Site that supplies services to other tenants, including wastewater treatment. The commenter said that Facility A does not use, produce, or emit EtO from any of its own processes; however, two tenants—Facility B and Facility C—are located inside the Industrial Site, and both emit EtO (and Facilities B and C are not subject to the HON but are subject to 40 CFR 63, subpart PPP). The commenter said that Facilities B and C send miniscule liquid EtO emissions to the WWTP for disposal; and reported emissions by Facility A of EtO from their WWTP, since taking over the Industrial Site, are less than 1 lb/yr. Using this example, the commenter contested that it is inappropriate to require Facility A to perform EtO fenceline monitoring and conduct a root cause analysis with subsequent corrective action because Facility A does not use, store, or emit EtO from any of their own production processes (
                        <E T="03">i.e.,</E>
                         Facility A only has EtO wastewater emissions from treating EtO wastewater from Facility B and Facility C as the site owner). The commenter made the following additional points: (1) The amount of EtO emitted to the air from wastewater obtained and treated by other facilities from Facility A has been less than a pound for the past 3 years; (2) the WWTP is located outside the fenceline of the Industrial Site; (3) Facility A does not have the authority to perform root cause analysis or corrective actions on facilities they do not have operational control over; and (4) if action level concentrations are found, it is not possible to determine whether the EtO comes from Facility B and/or Facility C, nor their individual contributions. For the Facility A WWTP, there is not a logical corrective action for emissions of less than 1 lb/yr that would change the EtO concentrations found in the ambient air. Other commenters provided similar examples and expressed similar concerns.

                         The EPA considered the potential applicability of fenceline monitoring as part of this proposed technology review. Generally, the EPA has found fenceline monitoring to be an effective tool when fugitive or ground-level releases are significant or where we have identified considerable uncertainties in HAP emissions estimates from fugitive emission sources such that they affect our decisions relative to whether there exists residual risk, for example. Other considerations include the types of pollutants that are emitted, the availability of fenceline monitoring measurement methods for the key pollutants, proximity of residences or other areas where people could be exposed to emissions at or near facility fencelines, and the other types of monitoring that are already required or are being considered.

                    <P>
                        Regarding the question of including onsite, non-source category emissions in the fenceline monitoring work practice standard, we proposed not to allow 
                        <PRTPAGE P="43004"/>
                        corrections to monitoring for onsite non-source category sources, as they were included in emissions sources modeled to develop the action levels. In other words, the action levels in the primary fenceline monitoring program are based on expected facility-wide emissions and account for contributions from these non-source category sources. For more details, see the document titled 
                        <E T="03">Clean Air Act Section 112(d)(6) Technology Review for Fenceline Monitoring located in the SOCMI Source Category that are Associated with Processes Subject to HON and for Fenceline Monitoring that are Associated with Processes Subject to Group I Polymers and Resins NESHAP</E>
                         (Docket Item No. EPA-HQ-OAR-2022-0730-0091) and the residual risk technical support document titled 
                        <E T="03">Residual Risk Assessment for the SOCMI Source Category in Support of the 2023 Risk and Technology Review Proposed Rule</E>
                         (Docket Item No. EPA-HQ-OAR-2022-0730-0085). The secondary action level for chloroprene adopted under CAA section 112(f)(2) appropriately anticipates the need for additional reductions of this pollutant in order to further the goal to protect public health from whole-facility chloroprene emissions. Further, in most cases, sources with HON or P&amp;R I source categories also account for a significant portion of the action level at the fenceline such that the option to attribute and correct monitors for emissions from collocated sources and equipment that may be used in processes associated with multiple source categories becomes a very complex and unnecessary process. In the Petroleum Refinery example, we note that the option to correct monitors for non-source category sources within the fenceline was found to be very difficult to implement practically and that the option was subsequently removed from most site-specific monitoring plans.
                    </P>
                    <P>We agree that the circumstance described by the commenter, although uncommon, might result in a situation where the most significant contribution would not be from the portions of the facility that are subject to the process limits established for the HON or P&amp;R I source itself. In this case we would apply the requirements based on how the source has been defined for the purposes of applicability of CAA section 112 standards, which is any stationary source or group of stationary sources located within a contiguous area and under common control. The commenter indicates that these facilities are not under common control, therefore Facility A would have to conduct fenceline monitoring because it does use, produce, and emit EtO, and it is subject to the HON, as the commenter indicates that it treats wastewater from Facilities B and C in its wastewater treatment process. In this case, Facility A could correct monitoring readings for offsite impacts using a site-specific monitoring plan. Depending on the orientation of Facilities B and C, this approach would require real-time monitoring of portions of the fenceline bordering Facilities B and/or C and is allowed by the proposed and final rule (see 40 CFR 63.184(g)). The commenter presumes that the amount of EtO emitted by the treatment process is miniscule, but that is precisely the question that fenceline monitoring is envisioned to address and to ensure that emissions are maintained at low levels. We believe even in this situation, the fenceline monitoring standard is reasonable and provides for an approach to address the commenter's concerns. Further, we reject the notion that our proposal failed to properly provide notice or to provide a meaningful opportunity to comment for all interested stakeholders. The major source to which these standards apply is by definition under common control. Unless the sources are subject to the HON and P&amp;R I standards, there is no requirement for operators of other source categories to comply with these requirements. Therefore, we reject the notion that this proposal is arbitrary and capricious and circumvents statutory design.</P>

                         With regard to the EPA's proposed fenceline monitoring requirements, numerous commenters contended that background concentrations need to be accounted for when calculating the incremental contributions from EtO-emitting facilities. A commenter said that without understanding the significance of high ambient background levels, it is not possible to determine a facility's true impact on ambient concentrations above the background level or the risk of EtO exposure. This commenter added that implementation of fenceline monitoring when background is unknown has the potential to generate data that will not represent what is intended, will require follow up action to correct problems that do not exist, and has the potential to frighten communities near facilities in the absence of elevated risk. Similarly, other commenters asserted that facilities are likely to show exceedances attributable not only to their own emissions, but also from background levels of EtO and emissions of EtO sources from offsite sources. These commenters said that background concentrations threaten a potentially endless cycle of investigations for the source of emissions which are beyond the EPA's regulatory authority or the facility's control; and the proposed fenceline monitoring requirements improperly attempt to turn facilities into mini ambient air quality regulators, requiring them to investigate and analyze fenceline exceedances that could be caused by another facility, background EtO levels, or simply an error in sampling due to the inability to accurately measure EtO at the incredibly low levels proposed.

These commenters as well as others said that background monitors in many cases show higher concentrations than monitors located within or nearby EtO-emitting facilities. Some of these commenters provided additional information about background EtO concentration data available from two studies conducted by state agencies:</P>

                        Commenters claimed that the reports published by the Georgia Department of Natural Resources, Environmental Protection Division, and by the West Virginia Department of Environmental Protection indicate that background concentrations of EtO can vary significantly, including up to more than an order of magnitude greater than EPA's proposed action level of 0.20 μg/m

Other commenters noted that the EPA's AirToxScreen presents EtO background levels as zero (so risks associated with background levels of EtO are not included in AirToxScreen maps and reports); however, according to commenters, this is highly unlikely to be the case, as shown by data in the EPA's NATTS sites, which are designed to be representative of community air toxics concentrations. Another commenter cited the West Virginia final report titled “Ethylene Oxide Monitoring—Characterization of South Charleston and Institute, West Virginia and Surrounding Areas February 21, 2023” and made the following observations of the measured EtO background concentrations from year 2018 through November 2021 at various monitoring points across the United States:

                    <P>Citing the EPA produced document titled “EPA's Work to Understand Background Levels of Ethylene Oxide” (most recently updated in October 2021), another commenter presented the following questions that they claimed to be unanswered: (1) Is EtO in use by unpermitted sites that are causing these levels?; (2) is EtO coming from other activities/sources such as mobile sources, biogenic sources?; and (3) when the IRIS inhalation URE value was developed, did the analysis include consideration of the background dosing?</P>

                        <E T="03">Response:</E>
                         We disagree with the commenters' assertions that background concentrations of EtO are not accounted for in the proposed fenceline monitoring provisions. The primary driving force for determining when a facility must initiate root cause analysis is the annual average Δc value; a root cause analysis is required whenever the annual average Δc value is higher than the action level. For EtO, the annual average Δc is the average of the most recent 73 individual sampling period Δc measurements. The sampling period Δc is calculated as the sampling period's highest sample result minus the sampling period's lowest sample result. If background EtO levels are persistent in the area, this will be captured by both the high and low concentration measurements used to develop the Δc values and the subtraction will result in only the facility's contributions to the EtO concentrations at the fenceline. As such, background levels are accounted for in the determination of each sampling period's Δc value, and subsequently the annual average Δc value.
                    </P>
                    <P>If, as commenters indicate, background EtO levels are inconsistent, the annual average Δc value must still shift above the action level before root cause analysis must be performed. The power of a single Δc value to cause undue root cause analysis is mitigated when it is averaged with the other measurements. Single events where background EtO levels are elevated will be insufficient to cause the annual average Δc to exceed the action level. If a single Δc value is large enough to skew the annual average derived from 72 other datapoints above the action level, the EPA expects that an emission event occurred and root cause analysis is appropriate.</P>
                    <P>Lastly, with respect to commenters' concerns that offsite facilities may contribute to EtO measurements at their facility, we note that owners and operators may submit site-specific monitoring plans to subtract background EtO concentrations from upwind emitters from impacted monitors pursuant to 40 CFR 63.184(g)(1) through (4).</P>
                    <P>The questions posed by the commenter about unpermitted sites emitting EtO or whether unknown sources are developing EtO are out of scope for this rulemaking. Section IV.A.3.a of this preamble addresses the EtO IRIS URE value.</P>

                        <E T="03">Comment:</E>
                         Several commenters requested that the EPA clarify that very small amounts of the six compounds (
                        <E T="03">i.e.,</E>
                         benzene, 1,3-butadiene, chloroprene, ethylene dichloride, EtO, and vinyl chloride) that may be produced, used, or stored at trace levels, as incidental by-products, and as impurities, should not trigger long-term fenceline monitoring requirements. Some of these commenters contended that the proposed applicability is unjustifiably broad, rendering it arbitrary and capricious. The commenters requested that the EPA provide a de minimis level that would trigger fenceline monitoring requirements; and several of the commenters also requested that the applicability be limited to regulated HON CMPUs. Some of the commenters requested that the EPA create exclusions for predetermined de minimis activities such as: housekeeping or building maintenance, lab and research activities, combustion emissions, transportation emissions, and incidental by-products or impurities. Similarly, a commenter asserted that the EPA uses the phrase “use, emit, or process” without any other criteria or definition of what this language means.
                    </P>
                    <P>A commenter pointed out that according to the EPA's AP-42 Compilation of Air Emission Factors, the combustion of fuels is likely to generate emissions of benzene and 1,3-butadiene (see AP-42, Tables 1.3-9, 1.4-3, 3.1-3, 3.3-2, and 3.4-3). The commenter added that since nearly all HON and NSPS III/NNN/RRR sources are expected to contain natural gas piping, and natural gas contains benzene, and the applicability of the fenceline monitoring requirement is based on site emissions, it is reasonable to conclude that nearly all HON and NSPS III/NNN/RRR sites are expected to be subject to the fenceline monitoring requirement regardless of whether the SOCMI processes at the site emit benzene or 1,3-butadiene. Another commenter said that implementing a fenceline monitoring program for any by-product/impurity that is intentionally minimized by the owner or operator is not cost-effective or environmentally beneficial, and as such, warrants additional consideration. The commenter stated that chloroprene is a by-product/impurity produced in their vinyl chloride monomer production process and would be emitted at much lower quantities than ethylene dichloride or vinyl chloride; and as described in the HON RTR Proposal, if the purpose of the fenceline program is to determine equipment leaks, the leaks would be more readily detected with vinyl chloride monomer or ethylene dichloride rather than through monitoring for a contaminant that may or may not be present in the process fluid.</P>
                    <P>
                        Commenters suggested that to avoid trace levels of these compounds triggering the monitoring programs, the EPA should establish additional applicability criteria for triggering the monitoring requirements given that the proposed fenceline air monitoring 
                        <PRTPAGE P="43006"/>
                        provisions are complex, take significant time to implement, and appear to be required for an infinite period. The commenters said the economic burden for fenceline monitoring is not justified for facilities with low levels of emissions (below de minimis thresholds) for any proposed fenceline compound. Some of these commenters recommended that the EPA clarify that when the EPA uses the phrase “if the site uses, produces, stores, or emits” one of the covered chemicals, this means that greater than 25,000 lb/yr of a chemical must be used, produced, or stored in HON CMPUs at the source. Commenters added that in order to trigger fenceline monitoring, the air emissions for a covered chemical should also be greater than 1 tpy (~ 0.23 lb/hr annual average) from HON CMPUs at the source. Commenters said that the rationale for using 25,000 lb/yr aligns with other EPA regulations such as 40 CFR 372.25(a) which is threshold for reporting of air emissions under the EPA's Superfund Amendments and Reauthorization Act Section 313 program; and a 1 tpy emission threshold (&lt;0.25 lb/hr) is a low threshold for then triggering the fenceline air monitoring program. Another commenter said that, given that the Agency selected the fenceline action levels by modeling emissions from the post-control emissions file in the residual risk assessment and selecting the maximum annual average fenceline concentration, one potential option for adopting a trigger threshold for fenceline monitoring would be to set emission thresholds at 50 percent of the source category emissions for the facilities that were used to set the proposed action level. The commenter said that this approach should also be applied for EtO and chloroprene because the Agency proposed to find acceptable risk and an ample margin of safety for these pollutants after implementation of the controls, thus making additional reductions of EtO and chloroprene unnecessary and unsupported by any rulemaking authority.
                    </P>
                    <P>A commenter suggested that if the EPA does not establish de minimis applicability thresholds, then the final rule should include a provision that allows for fenceline monitoring to be discontinued at a site after 2 years of non-detect fenceline monitoring concentrations for a compound. The commenter said that a site with non-detect fenceline concentrations does not drive the risk assessment for that compound.</P>

                         The EPA disagrees with commenters that the fenceline monitoring provisions are unjustly broad. Per 40 CFR 63.184, the fenceline monitoring provisions are applicable “for each source as defined in § 63.101, and for each source as defined in § 63.191.” The definitions of source at 40 CFR 63.101 and 40 CFR 63.191 point to 40 CFR 63.100 and 40 CFR 63.190, respectively, where applicability is stated. For the HON, only those sources manufacturing as a primary product one or more of the chemicals in Table 1 to NESHAP subpart F, or tetrahydrobenzaldehyde, or crotonaldehyde; or using as a reactant or manufacturing as a product, or co-product, one or more of the HAP listed in Table 2 to NESHAP subpart F are subject to the provisions. For NESHAP subpart I, only those emissions specified from the processes subject to 40 CFR 63.190(b)(1) through (6) are subject to the fenceline provisions. Therefore, any concerns about obligations to meet fenceline monitoring requirements for pollutants developed as impurities or found in feedstock in trace amounts are unfounded, as these materials are not “products,” which, by definition, exclude by-products, isolated intermediates, impurities, wastes, and trace contaminants per the definition at 40 CFR 63.101 or, in the case of NESHAP subpart I, are not the specified pollutants from the processes to which the subpart applies. For P&amp;R I sources subject to NESHAP subpart U, we note that the fenceline monitoring requirements reference 40 CFR 63.101 and the same logic can be applied.
                    </P>
                    <P>To the commenter's assertion about emissions from boilers, housekeeping, building maintenance, or lab and research activities triggering fenceline monitoring requirements, we note that these are not considered within SOCMI or P&amp;R I sources per the applicability of the term at 40 CFR 63.100. Thus, there would be no need to implement fenceline monitoring if these are the only sources emitting benzene, 1,3 butadiene, ethylene dichloride, vinyl chloride, EtO, or chloroprene at a facility. Therefore, for the reasons previously stated, there is no need to set a minimum threshold for fenceline monitoring as the rule already provides criteria targeting only SOCMI or P&amp;R I sources using, producing, storing, or emitting one or more of the six considered pollutants and will not be triggered by low-level emissions from non-source category processes.</P>
                    <P>However, we agree with the commenter that the proposed language could be interpreted such that emissions from non-HON or P&amp;R I processes could trigger the fenceline monitoring requirement. As such, we are revising 40 CFR 63.184(a)(1)(i) through (iv) and 40 CFR 63.184(b)(1)(i) and (ii) to state that owners and operators with an affected source that uses, produces, stores, or emits one or more of the target analytes must conduct fenceline monitoring for the analyte(s) at their site. At proposal, we inadvertently used the word site in these sections instead of affected source, which may have led to confusion that non-HON or P&amp;R I processes could have triggered fenceline monitoring obligations when there were no HON or P&amp;R I processes at the site that use, produce, store, or emit benzene, 1,3 butadiene, ethylene dichloride, vinyl chloride, EtO, or chloroprene. We believe this change clarifies our original intent and helps to more clearly target those facilities that were identified as needing fenceline monitoring as part of our original analysis (see Docket Item No. EPA-HQ-OAR-2022-0730-0091).</P>
                    <P>
                        To address concerns with facilities producing, using, storing, or emitting only low levels of benzene, 1,3-butadiene, ethylene dichloride, or vinyl chloride, we are finalizing burden reduction measures at 40 CFR 63.184(a)(3)(iii) and (b)(2)(iii). These provisions, similar to those provided at 40 CFR 63.658(e)(3) of NESHAP subpart CC for benzene, will allow facilities to skip fenceline measurement periods for specific monitors once a certain number of fenceline measurements are recorded to be one tenth or less than the finalized action levels. We believe the addition of these provisions will unify the finalized fenceline monitoring provisions between NESHAP subpart H and NESHAP subpart CC so that collocated refinery processes will not become subject to additional monitoring if they have already demonstrated levels of benzene at the fenceline that allow the owner or operator to qualify for a reduced sampling frequency and support facilities producing, using, storing, or emitting only low levels of the targeted pollutants from their affected sources. We note that these provisions are not being provided for EtO and chloroprene due to their associated risk and the finalized secondary actions levels having been set at three times the representative detection limit (RDL), and thus demonstrating sufficiently low fenceline concentrations to allow skipping monitoring periods is not possible. Additionally, for both EtO and chloroprene, even for the primary action levels, one-tenth of the action level would be below the method detection limit (MDL), and as such, skipping monitoring periods would not be possible for these pollutants. We also

                        note that for vinyl chloride, this option is limited to small sites with perimeters less than or equal to 5,000 meters. We have chosen to limit the reduced sampling frequency to these smaller sites because these are the only sites where the canister samples are taken at the same sampling location each sampling period; owners and operators of sites with a perimeter larger than 5,000 meters are required to rotate the sampling locations between sampling periods. As such, this complicates the determination as to whether a larger site has consistently low fenceline readings at a particular monitoring location.

                         A commenter pointed out that when fenceline monitoring was established for refineries, the EPA stated that benzene was specifically chosen as the target analyte for petroleum refineries with the understanding that a single HAP served as a surrogate for all fugitive HAP, further stating that a single HAP simplified the determination of compliance and set a clear action level. The commenter contested that it is unclear why benzene cannot be the surrogate for the species listed under the proposed EPA Method 325 fenceline monitoring requirements. Moreover, the commenter added that a site should only have to do the chlorinated species or EtO monitoring if it is present in sufficient quantities such that their emissions would create a concentration higher than MDL at the perimeter; the commenter asserted that the EPA set their action levels based on modeling of site emission inventories but did not incorporate any rationale for why sites with less emissions must do such expensive monitoring. The commenter suggested that sites should have the option to model or demonstrate that their emissions would not be expected to exceed the action levels without embarking on a costly monitoring program that will just be reporting below detection level values.

                         Benzene was selected as a surrogate for all HAP as part of the fenceline monitoring provisions of NESHAP subpart CC due to its near universal presence in process streams. HON and P&amp;R I processes are more diverse and there is no single chemical that is found with the same frequency in process streams as benzene in petroleum refineries. Setting one surrogate chemical to represent the variety of HON and P&amp;R I processes considered as part of this rulemaking would not produce effective standards limiting fugitive emissions.

                        To the commenter's request to be able to model concentrations at the fenceline to show that action levels will not be met, we point to table 2 through table 7 in the document titled

                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0091). Fugitive emissions are, by nature, difficult to measure and record and the data collected via the CAA section 114 request indicates that modeling is insufficient to anticipate fenceline concentrations of the six target pollutants considered. Therefore, we maintain that it is reasonable to require monitoring if a facility whose SOCMI or P&amp;R I affected sources use, produce, store, or emit any of the pollutants specified at 40 CFR 63.184 to verify that actual concentrations at fenceline are below the finalized action levels.

                         Commenters said that they have concerns regarding equipment and lab analytical capabilities on whether any laboratory is capable of performing proposed EPA Method 327. The commenters asserted that they were only able to identify one lab in North America that could meet all requirements of proposed EPA Method 327. A commenter suggested that to the extent that fenceline monitoring for EtO is required, the EPA should allow for the use of EPA Method TO 15 for initial monitoring for at least one (1) year until lab capabilities are further established; or alternatively, the initiation of fenceline monitoring be moved to at least two (2) years after the effective date of the final rule. Another commenter encouraged the EPA to actively engage in dialogue with commercial air laboratories in the method review process to ensure that the procedures meet the EPA's quality objectives of the program and also can be supported on a production scale, both of which will be critical for the successful implementation of the canister fenceline monitoring network. Another commenter requested that the EPA provide a list of laboratories able to perform proposed EPA Method 327.

                    <P>A commenter recommended that the EPA work with the New York State Department of Environmental Conservation (NYSDEC) to improve proposed EPA Method 327 given that NYSDEC analyzes VOCs in-house and has devoted considerable resources into refining its EtO measurement procedures over a seven year period. The commenter claimed that in a recent EPA performance audit of the NYSDEC laboratory required for NATTS sites, NYSDEC's EtO results were well within the 20 percent acceptability range and outperformed the referee laboratory. The commenter said proposed EPA Method 327 does not adequately address the issues that lead to inaccurate EtO measurements including, but are not limited to, the following:</P>

Ion 15 was too noisy and ion 29 suffered from interference due to background contributions from nitrogen. For NYSDEC, interference from trans 2-butene for ion 44 was not found to be an issue for normal ambient air samples due to the relatively low concentration of that substance in those samples. However, trans-2-butene can interfere with quantitation using ions 15 or 19, because, unlike ion 44, those are prominent masses in the mass spectrum of trans-2-butene.</P>

                        • The use of internal standards for quantitation should not be mandated, especially for reactive chemicals like EtO and acrolein, as that procedure can produce biased results when the internal standard is not as sensitive to instrumental conditions as the target chemical. A better approach would be to use isotope dilution for the quantitation of these compounds, as the doped compounds would presumably react the same way in the analytical system. Given the anticipated very costly procurement of such internal standards, this should not be mandated, but instead suggested as a means to improve analytical performance for these reactive compounds. NYSDEC calibrates before, during, and after each analysis using the external standard approach and has complete confidence that the instrument is producing the best data within the confines of the system.

                         The EPA recognizes the commenters' concerns that laboratories may not currently have the capacity to conduct EPA Method 327 according to the timeline we proposed. Therefore, we are revising the final rulemaking at 40 CFR 63.100(k)(12) (for HON) and 40 CFR 63.481(p) (for the P&amp;R I NESHAP) such that with the exception of fenceline monitoring of chloroprene at P&amp;R I affected sources producing neoprene, owners and operators are not required to initiate fenceline monitoring until 2 years after the effective date of the final rulemaking. This expanded timeline is necessary to allow commercial labs to conduct the needed method development, to expand capacity, and to develop the logistics needed to meet the requirements in the final rule. For P&amp;R I affected sources producing neoprene, we have changed the compliance date for fenceline monitoring of chloroprene to begin no later than October 15, 2024, or upon startup, whichever is later subject to the owner or operator seeking the EPA's authorization of an extension of up to 2 years from July 15, 2024. We note that that all affected sources producing neoprene (there is only one) already have a fenceline monitoring network in place for chloroprene as well as a lab contracted to provide analysis.

                    <P>We developed EPA Method 327 based on the requirements in EPA Method TO-15A, best practices for measuring compounds like EtO, and enhanced QA/QC required for a method that is to be used for compliance purposes. Regarding the specific recommendations made by the commenter, the EPA has made EPA Method 327 as performance-based as possible and considers it important, when possible, to avoid prescriptive requirements to allow commercial laboratories to develop their own approaches for analysis.</P>

                         Some commenters said that the EPA's proposed 300 parts per trillion (ppt) detection limit for EtO (and 900 ppt fenceline action threshold) are inadequate given that carcinogenic effects can be persistent and cumulative. These commenters claimed that EtO is toxic at 11 ppt in the ambient air; therefore, the EPA should mandate the use of advanced monitoring technologies to achieve lower detection limits and lower the action levels at the fenceline. A commenter remarked that in Louisiana, the typical residential location is not set at some safe distance from emissions; therefore, it is proper for the EPA to set minimum detection levels at the fenceline of the facility's property line, and not set the minimum detection level scalable to the duration of dispersion from the facility to the residential receptor location. Another commenter argued that developments in monitoring technology that lower the detection levels for listed HAP must be considered technological developments under CAA section 112(d)(6). This commenter contended that new technological developments, such as the use of proton transfer reaction-mass spectrometers and the use of Picarro products that use cavity ring-down spectrometers should be adopted by the EPA in its efforts to lower emissions in these source categories with the proposed fenceline monitoring efforts in the rules.

                        Another commenter declared that it is important to note that the method detection limit is nearly the same as the concentration that is representative of 100-in-1 million risk; therefore, any detection corresponds to an unacceptable level of risk. On the contrary, a commenter said that given ambient air measurements made using the EPA's TO-15/TO-15A summa canister method have a detection limit for EtO higher than 0.02 ug/m
                        <E T="51">3</E>
                        , it is possible that the actual level could be above the EPA's 100-in-1 million risk level even if a regulated source or an agency were to obtain non-detect results. This commenter said that they are very concerned that the EPA has established ambient air targets that neither an industrial source nor a regulatory agency can demonstrate that they are meeting with current air sampling methods; this raises practical questions about how one demonstrates compliance with these air quality targets.

                         The EPA recognizes the feedback from the commenters. We evaluated multiple measurement approaches that could be used for fenceline measurement, and there currently is not a measurement approach with reliable sensitivity at the level representative of 100-in-1 million cancer risk. The EPA found the only technically feasible approach to measure EtO at the fenceline is a canister measurement approach and analysis via gas chromatography/mass spectrometry (GC/MS). We developed EPA Method 327 based on the requirements in TO-15A, the EPA's existing canister method, Best Practices for measuring compounds like EtO, and enhanced QA/QC required for a method to be used for numerical compliance purposes.

The EPA disagrees with the commenters that these real-time monitoring approaches are currently sensitive enough to currently be applied to fenceline monitoring; however, the EPA has a pathway for the use of these potential approaches through the alternative test method provisions in 40 CFR 63.7(f) when the required sensitivity is met, which is outlined in 40 CFR 63.184(i). We note that based on response to another comment, we are revising the entry for 40 CFR 63.7(f) in the General Provisions table to NESHAP subpart F (Table 3) such that 40 CFR 63.7(f) applies.</P>

                         Many commenters expressed concerns that the proposed provisions for an alternative test method at 40 CFR 63.184(i)(3) require the method detection limit of the alternative method to be at least an order of magnitude (
                        <E T="03">i.e.,</E>

                        <E T="51">3</E>
                         for EtO will prohibit some otherwise potentially viable alternative monitoring methods, including the Picarro air monitoring system and many open-path technologies. Commenters recommended that the EPA remove 40 CFR 63.184(i)(3) in its entirety. Commenters indicated that this requirement limits flexibility and the ability for evaluation of alternate methods via the EPA's current alternate methods processes.

                        A commenter further indicated that the proposed action levels for EtO and chloroprene are three times the RDL for each compound and, according to the EPA's technical memorandum, three times the RDL represents the level where a test method performs with acceptable precision. However, the commenter recommended that the EPA increase the multiplier to 5 for EtO for consistency with proposed EPA Method 327. The commenter argued that the requirement at 40 CFR 63.184(i)(3) for a ten-fold reduction in MDL for alternative test methods is so restrictive as to potentially eliminate the flexibility of real-time monitoring because the MDL was only five times lower than an already very low action level. The 
                        <PRTPAGE P="43009"/>
                        commenter suggested the EPA revise the language at 40 CFR 63.184(i)(3) to require methodologies with detection limits at or below those of the reference standard (
                        <E T="03">i.e.,</E>

                         The EPA agrees with the commenters that the proposed requirement that the MDL of the alternative method be at least an order of magnitude less than the action level is too restrictive, and, therefore, in the final rule we have revised the requirement at 40 CFR 63.184(i)(3) that the method detection limit of an alternative test method must be at least one-third of the action level for the compound(s) that will be monitored with the alternative method. The EPA considers three times the MDL to describe the limit of quantification of a method, or the point at which we have confidence in the accuracy and precision of a method. We note this requirement is also consistent with the EPA's approach for setting emission limits that are at least three times the RDL. Such an approach ensures that the standard is at a level that addresses measurement variability and is in a range that can be measured with reasonable precision. Requiring the detection limit of alternative measurement approaches to be at least one-third of the action level will ensure that measurements made near the action level are of reasonable precision.
                    </P>
                    <P>We note that while the EPA has reduced the requirements for the minimum detection limit of alternative measurement approaches, when calculating the sampling period Δc, an owner or operator must still use zero as the lowest sample result when a measurement is below the MDL and must still use the MDL as the highest sample result if all sample results are below the MDL. The use of this approach in determining Δc incentivizes the use of technology capable of measuring the lowest possible concentration for the target compound.</P>

                         Several commenters said that they opposed the EPA's proposal to eliminate the TRE index value concept in the new NSPS subparts IIIa, NNNa, and RRRa. The commenters provided the following arguments:
                    </P>
                    <P>
                        • The TRE index value has been an integral part of many technology-based air standards since its initial development, serving as a mechanism for determining cost effectiveness and triggering the requirements for process vent control (see, 
                        <E T="03">e.g.,</E>
                         the preamble to the 1994 HON adoption, which states that the TRE concept is appropriate because it “can be used to reflect all possible combinations of various factors that affect emission rates and likelihood of current control” (citing 59 FR 19416) and “would provide consistency between the HON[,] the recently issued [control techniques guidelines] for SOCMI process vents. . .[and] the applicability criteria for the three SOCMI process vents NSPS” (59 FR 19418)). The EPA determined that BSER was 98 percent control (or an outlet concentration of 20 ppmvd at 3 percent O
                        <E T="52">2</E>
                        ) of sources with a TRE less than or equal to 1.0 when it promulgated these rules.
                    </P>
                    <P>• While the EPA discusses its basis for removing the TRE index value &gt; 1.0 alternative emission standard, it provides no discussion for why the limited applicability exemption in the NSPS (TRE &gt; 4.0 for NSPS subpart III and TRE &gt; 8.0 for NSPS subparts NNN and RRR) is proposed to be removed. The EPA must explain why this exemption should be removed and provide an opportunity for the public to comment before taking final action to modify or remove it.</P>
                    <P>• Voluntary control of some process vents with a TRE index value greater than 1.0 does not imply that controlling all process vents with a TRE index value greater than 1.0 constitutes the BSER. While controlling a subset of process vents with a TRE index value greater than 1.0 may be cost effective, the EPA's cost analysis for controlling such vents significantly understates the cost of installing additional controls such as a thermal oxidizer.</P>
                    <P>• The fact that a control device at one stationary source controls multiple process vents (as opposed to a single process vent) does not mean that in all cases control of multiple process vents is cost-effective. If the cumulative emissions from the process vents are small, then even controlling all of them with one control device is not cost effective.</P>
                    <P>• The EPA's conclusion that the TRE index value calculation is theoretical, complex, uncertain, and difficult to enforce is overly broad and cannot be applied to the regulated industry as a whole. The issues the EPA cites related to calculation of the TRE index value do apply in instances with few organic compounds in the stream, and in instances where facilities have readily available process data obtained from source testing, other direct measurements, or permit limits. Observations from one facility's TRE index value calculation approach should not be construed as representative of 284 facilities.</P>
                    <P>
                        • The EPA's cost analysis (see Docket Item No. EPA-HQ-OAR-2022-0730-0011) is not well supported and significantly underestimates the cost of installing and operating a thermal oxidizer. The EPA presents a total annual cost of $98,429 and a VOC emissions reduction of 9.1 tpy from the elimination of the TRE concept and the imposition of control requirements for all process vents. The EPA references the HON technology review memorandum in support of the cost calculations; however, that memorandum does not include a cost analysis of emission reduction calculations for NSPS sources. Furthermore, the EPA's proposed capital cost of $65,577 for a thermal oxidizer sized to control a 10 scfm stream is unrealistic; and it is also unrealistic to assume that a facility would install a thermal oxidizer simply for a 10 scfm stream. The EPA's cost algorithm significantly underestimates the costs associated with design and engineering of such projects. A commenter provided an example at one of their existing affected facilities where if NSPS NNNa is triggered via modification or reconstruction, the facility would need to install control equipment estimated at a conservative amount of $500,000 in order to control 0.07 tpy of VOC result from vents from recovery scrubbers, or about $7.14M per ton of VOC removed. The commenter 
                        <PRTPAGE P="43010"/>
                        suggested that if the EPA is going to eliminate the TRE concept, that the EPA consider a cost effectiveness cut-off that is scaled to inflation that could avoid absurd results such as this.
                    </P>
                    <P>• The EPA has ignored the fact that facilities that would now be required to control Group 2 halogenated streams would not only have to control organic HAPs using a thermal oxidizer, but would also have to incur costs to design, engineer, and install controls for acid gas and dioxin/furan emissions.</P>
                    <P>A commenter questioned why removing the TRE concept for the SOCMI sector is not arbitrary given that no action was taken on the TRE concept in the recent RTR of the MON, conducted just 3 years ago.</P>

                        Some commenters suggested that the EPA could keep the TRE index value concept but raise the threshold, or establish a mass-based criterion below which emission controls are not required such that the rules would only require control where it is cost-effective (
                        <E T="03">e.g.,</E>
                         limit applicability of the NSPS to affected facilities at a site whose cumulative VOC emissions are greater than 25 tpy). A commenter pointed out that the proposed HON rulemaking requires control of process vents that emit greater than 1.0 lb/hr of total organic HAP, and suggested that a similar mass-based VOC emissions threshold below which control is not required be added to the SOCMI NSPS rules to avoid control being required for vent streams with very negligible VOC emissions. The commenter pointed out that the EPA included a mass-based emission threshold in NSPS subpart DDD at 40 CFR 60.560(g). The commenter provided an example of one of their distillation columns where the vacuum jet system vent emits very low amounts of VOC emissions (&lt;0.0001 lb/hr uncontrolled), the net heating value is very low or negligible, and the vent stream contains primarily nitrogen and/or water vapor. The commenter said that they would have to then build an emission control device to manage this stream.

                         As stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), the statutory review of these process vent NSPS (subparts III, NNN, and RRR) focused on whether there are any emission reduction techniques used in practice that achieve greater emission reductions than those currently required by the current NSPS and whether any such practices have become the BSER. Based on this review, we have determined that the BSER for reducing VOC emissions from these SOCMI processes remains combustion (
                        <E T="03">e.g.,</E>
                         incineration, flares), and that the current emission standard of 98 percent reduction of TOC (minus methane and ethane) or reduction of TOC (minus methane and ethane) to an outlet concentration of 20 ppmv on a dry basis corrected to 3 percent oxygen continues to reflect the BSER.
                    </P>
                    <P>
                        While we found no change in the BSER for reducing VOC emissions from air oxidation units, distillation operations, and reactor processes, we are finalizing the removal of the entire TRE concept, including the alternative of maintaining a TRE index value greater than 1 without the use of control device and the limited applicability exemptions (
                        <E T="03">i.e.,</E>
                         TRE &gt; 4.0 for NSPS subpart III and TRE &gt; 8.0 for NSPS subparts NNN and RRR) for purposes of NSPS subparts IIIa, NNNa, and RRRa. We stand by the rationale we provided in the preamble to the proposed rule for not including the TRE concept in NSPS subparts IIIa, NNNa, and RRRa, which is summarized as follows: (1) Based on the responses to our CAA section 114 request, we observed that some facilities are controlling continuous process vents that are not required by the NSPS subparts III, NNN, or RRR to be controlled per the results of the TRE index value calculation; (2) based on the responses to our CAA section 114 request, we observed that facilities are routing multiple continuous process vents to a single APCD; (3) determining a TRE index value for certain process vent streams is often theoretical, can be extremely complicated, and is uncertain; and (4) because the TRE index value is largely a theoretical characterization tool, it can be very difficult to enforce.
                    </P>
                    <P>As stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), in reviewing an NSPS to determine whether it is “appropriate” to revise the standards of performance that reflects the degree of emission limitation achievable through application of BSER, the EPA considers the following information:</P>
                    <P>• Costs (including capital and annual costs) associated with implementation of the available pollution control measures.</P>
                    <P>• The amount of emission reductions achievable through application of such pollution control measures.</P>
                    <P>• Any non-air quality health and environmental impact and energy requirements associated with those control measures.</P>
                    <P>• Expected growth for the source category, including how many new facilities, reconstructions, and modifications may trigger NSPS in the future.</P>
                    <P>• Pollution control measures, including advances in control technologies, process operations, design or efficiency improvements, or other systems of emission reduction, that are “adequately demonstrated” in the regulated industry.</P>
                    <P>• Available information from the implementation and enforcement of current requirements indicating that emission limitations and percent reductions beyond those required by the current standards are achieved in practice.</P>
                    <P>
                        As previously stated, some owners and operators do not use the TRE index value to determine whether a vent stream is required to be controlled. While we agree with commenters that owners and operators control vent streams that have a TRE index value greater than 1.0 for reasons other than the desire to avoid the TRE calculation, the fact is that owners and operators are controlling vent streams that have a TRE index value greater than 1.0 (possibly to comply with state or local regulations regarding VOCs or to meet a BACT limit), which is information relevant to our CAA section 111(b)(1)(B) review of the standards. Given that the TRE concept has been used since each original NSPS adoption, we consider owners and operators controlling vent streams that have a TRE index value greater than 1.0 to be a pollution control measure (
                        <E T="03">i.e.,</E>
                         an advance in process operations) in our analysis. Additionally, the removal of the TRE concept simplifies the determination as to whether owners and operators must control a vent stream and thus, the applicability process is easier to implement.
                    </P>
                    <P>
                        We disagree with commenters' assertions that the EPA did not provide evidence that the TRE concept is largely theoretical and, as a result, difficult to verify. As identified in the document titled 
                        <E T="03">Clean Air Act Section 112(d)(6) Technology Review for Continuous Process Vents Located in the SOCMI Source Category that are Associated with Processes Subject to HON, Continuous Front-end and Batch Front-end Process Vents Associated with Processes Subject to Group I Polymers and Resins NESHAP, and Process Vents Associated with Processes Subject to Group II Polymers and Resins NESHAP</E>
                         (Docket Item ID No. EPA-HQ-OAR-2022-0730-0094), one facility that received the CAA section 114 request provided over 300 pages of modeled runs used to determine certain characteristics of their continuous process vents to be utilized as part of the TRE index value calculations. Reviewing this information revealed 
                        <PRTPAGE P="43011"/>
                        that in many cases, the facility struggled to unify the modeled runs with actual conditions at the facility and in some cases made arbitrary decisions to allow the model to function. While we agree with commenters that the TRE index value can be derived from less theoretical methods, other responses to the CAA section 114 request did not indicate how parameters used in the TRE index value calculations were determined and commenters did not provide sufficient information to show which methods were most common throughout industry. Given the theoretical nature of the TRE index value, the EPA maintains that verifying TRE index values is arduous because it can involve relying on significant process knowledge in order to confirm compositions of vent streams, vent stream flowrates, vent stream net heating values, and hourly emissions. It may also require verification of other facility assumptions (
                        <E T="03">e.g.,</E>
                         operational conditions and constraints), especially if modeling was used. This logic applies equally to existing, new, and modified sources and thus is one of the reasons why the EPA is not including the TRE concept in NSPS subparts IIIa, NNNa, and RRRa as part of this rulemaking.
                    </P>
                    <P>
                        We agree with commenters that the TRE index value has been an integral part of many technology-based air standards since its initial development. In fact, we said as much in the document titled 
                        <E T="03">CAA 111(b)(1)(B) review for the SOCMI air oxidation unit processes, distillation operations, and reactor processes NSPS subparts III, NNN, and RRR</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0011). The TRE concept is almost 40 years old; it was first introduced in a December 1984 EPA document (EPA-450/3-84-015; see attachment to Docket Item No. EPA-HQ-OAR-2022-0730-0011). However, even if it has been used in the past, we believe that for purposes of the new NSPS subparts NNNa, IIIa, and RRRa, certain aspects of its underlying development are clearly no longer applicable or appropriate. For example, the EPA stated in the 1984 supporting materials (EPA-450/3-84-015) that the Agency attempted to make the TRE index independent of inflation (
                        <E T="03">e.g.,</E>
                         the EPA assumed fixed relative costs of various resources, such as carbon steel and electricity), yet it is impossible to ignore inflation in the TRE calculations due to the time that has passed since it was developed (
                        <E T="03">e.g.,</E>
                         costs of carbon steel and electricity have undoubtedly increased since the development of the TRE index).
                    </P>
                    <P>Although the TRE index value may allow owners and operators to allocate resources efficiently and ensure that the most significant emission sources are targeted for control, the current use of the TRE index value is only based on controlling a single vent stream with a single APCD. This is an unrealistic scenario when compared to how affected facilities actually control their vent streams; it is much more likely that a facility routes numerous vent streams to the same APCD (which is evident from observing the responses to our CAA section 114 request).</P>
                    <P>
                        We do agree with commenters that our cost estimate for installing a new recuperative thermal oxidizer (to control vent streams subject to the NSPS) included in the proposed rule is unrealistic (
                        <E T="03">e.g.,</E>
                         we severely underestimated flow rates needed to route vent streams with low flow to APCDs). Although we still believe the use of the EPA's control cost template is appropriate to estimate the cost of installing a new recuperative thermal oxidizer (to control vent streams subject to the NSPS), we revised our estimates to reflect the limitations of the correlations associated with the EPA's control cost template, which starts with a flow rate of 500 scfm. With these corrections, we estimate that the average TCI to install a new recuperative thermal oxidizer is about $167,000 (as opposed to the $66,000 estimate provided in the proposed rule). However, our estimate is still much less than the $500,000 estimate provided by commenters. One explanation for this is that commenters may have used a much higher flow rate (
                        <E T="03">e.g.,</E>
                         5,000 scfm as opposed to 500 scfm) and a “Regenerative Thermal Oxidizer” in their cost analysis instead of a “Recuperative Thermal Oxidizer.” Moreover, commenters did not provide supporting information for their estimated capital costs, so the EPA cannot corroborate their assertions regarding cost.
                    </P>
                    <P>
                        In light of the fact that commenters were generally concerned about the cost estimate for installing a new recuperative thermal oxidizer (to control vent streams subject to the NSPS), we performed additional analyses to evaluate the cost effectiveness of not including the TRE concept in the new NSPS IIIa, NNNa, and RRRa. Instead of using $500,000 as suggested by a commenter, we used a TCI of $1,000,000 and the EPA's control cost template (for installing a new recuperative thermal oxidizer with 70 percent energy recovery). Even with this change in our analysis, we continue to believe that revising the standard from a TRE calculation to control of all vent streams is still cost effective when considered along with the suite of process vent requirements evaluated as a whole under our NSPS review. As stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), we considered four different NSPS-triggering scenarios and a suite of proposed process vent requirements combined together (including not only revising the standard from a TRE calculation to control of all vent streams, but also new operating and monitoring requirements for flares, the addition of maintenance vent requirements, and the addition of adsorber monitoring requirements). In this context, we conclude that, even with our reevaluation of TCI for installing a new recuperative thermal oxidizer, the cost-effectiveness value of the suite of process vent requirements evaluated under our NSPS review is $4,890 per ton VOC (instead of $4,570 per ton VOC as proposed), which we consider to be reasonable.

                    <P>We disagree with the commenters' suggestion to include the TRE concept in the new NSPS subparts NNNa, IIIa, and RRRa but raise the TRE index value threshold to something greater than 1.0 (as opposed to not including the TRE concept in its entirety, as proposed). Regarding a commenter's assertion that removing the TRE concept is arbitrary given no action was taken on the TRE concept in the MON RTR, we note that we did not have data related to Group 2 process vents while developing revisions to the MON. Setting an emission threshold with no knowledge of which Group 2 MON vent streams would be impacted and the potential cost or reductions associated with that revision would not have been appropriate.</P>
                    <P>
                        Finally, we agree with the commenter's request to include a mass-based criterion below which emission controls are not required, but only for NSPS subparts IIIa and NNNa (not NSPS 
                        <PRTPAGE P="43012"/>
                        subpart RRRa). We believe a mass-based exemption criterion is not needed for NSPS subpart RRRa given that we are finalizing, as proposed, a volumetric flowrate-based exemption (0.011 scm/min at 40 CFR 60.700a(c)(3)) as well as a concentration-based exemption (300 ppmv TOC as measured by EPA Method 18 or 150 ppmv TOC as measured by EPA Method 25A at 40 CFR 60.700a(c)(7)) in NSPS subpart RRRa. It is clear from supporting documents that the EPA included the concentration-based exemption in NSPS subpart RRR with the intent to relieve owners and operators of controlling vent streams with very low amounts of VOC emissions (see 58 FR 45948, August 31, 1993, as well as the document titled 
                        <E T="03">Selection of the Low Concentration Cutoff,</E>
                         which is available in the docket for this rulemaking). Even so, we recognize that NSPS subparts IIIa and NNNa do not contain these same exemptions. Therefore, we are finalizing a mass-based exemption criterion of 0.001 lb/hr TOC (for which emission controls are not required) for NSPS subparts IIIa and NNNa at 40 CFR 60.610a(c)(1) and 40 CFR 60.660a(c)(6), respectively. We based this criterion on the combination of both the volumetric flowrate- and concentration-based exemptions that are included in NSPS subparts RRR and the final RRRa. In other words, the 0.001 lb/hr TOC mass-based exemption criterion which we are finalizing in NSPS subparts IIIa and NNNa is roughly equal to a vent stream with a volumetric flowrate of 0.011 scm/min and a TOC concentration of 300 ppmv (assuming a TOC molecular weight of 80 grams per mole) included in NSPS subparts RRR and the final RRRa. We also note that new affected facilities should have greater flexibility in selecting cost-effective control options during the design and construction phase (
                        <E T="03">e.g.,</E>
                         owners and operators at greenfield sources are likely to have more flexibility in spatial considerations compared to those at an existing source leading to a potential reduction in the amount of complex piping and construction materials needed to install an APCD).

                        <E T="03">Comment:</E>
                         A commenter said they support the EPA's proposal to eliminate the relief valve discharge exemption from the definition of “vent stream” in NSPS, subparts IIIa, NNNa, and RRRa such that any relief valve discharge to the atmosphere of a vent stream is a violation of the emissions standard. However, several other commenters opposed this proposal. Commenters requested that the EPA revise the term “violation” to “deviation” in NSPS subparts IIIa (at 40 CFR 60.612a(b)), NNNa (at 40 CFR 60.662a(b)), and RRRa (at 40 CFR 60.702a(b)) regarding the prohibition of relief valve discharges (
                        <E T="03">e.g.,</E>
                         PRD releases to the atmosphere) and use of bypass lines. In addition, the commenters requested that the EPA add the same PRD work practice standard that the EPA has finalized in the MON (at 40 CFR 63.2480(e)(3)- (8)) and Ethylene MACT (at 40 CFR 63.1107(h)(3)-(8)), and proposed in the HON (at 40 CFR 63.165(e)), into NSPS subparts IIIa, NNNa, and RRRa at 40 CFR 60.612a(d), 60.662a(d), and 60.702a(d), respectively. The commenters argued that the proposed regulatory approach regarding eliminating the relief valve discharge exemption does not represent BSER for the SOCMI source category given that relief valve discharges that are routed to the atmosphere are necessary at times for at least the following reasons:
                    </P>
                    <P>• Hazardous oxidation products: A discharge to a flare would result in combustion products that are not desirable.</P>
                    <P>• Chemical reactivity within flare system: Some affected facilities may use a single large flare for emission control for a given process area or group of process areas.</P>
                    <P>• Physical obstruction within flare header system: In some cases, there is a potential for certain compounds to block or restrict portions of the flare header.</P>
                    <P>• Streams containing oxygen: Some process streams and equipment that PRDs protect contain mixtures of organic compounds and oxygen especially in air oxidation processes. Some air oxidation reactors have rupture discs as PRDs, and swings in air supply can cause a rupture disc to fail.</P>
                    <P>• Intolerable backpressure on the PRD: The operating pressure in a large flare header system could increase from just slightly over atmospheric pressure to a pressure in the 10-20 psig range or higher for certain periods of time when upset venting occurs or another highly intermittent flow occurs.</P>
                    <P>• Intolerable liquid load on the flare Knock Out (KO) drum: If the PRD is in liquid service, it is not acceptable to add a high-volume liquid discharge from a PRD into a flare header. Flare KO drums have a finite liquid capacity. If the liquid is highly volatile, severe pipe contraction (due to auto-refrigeration) can potentially cause a loss-of-containment failure of the flare header piping.</P>
                    <P>• Technically impossible to collect discharges from PRDs on portable/mobile containers.</P>
                    <P>• It is not technically or economically feasible to install a new large flare system to capture the discharge from a small number of new PRDs from a new, reconstructed, or especially a modified SOCMI source regulated under NSPS subparts IIIa, NNNa, and RRRa.</P>
                    <P>
                        • Any chemical manufacturing facility with the potential to release high volumes of chlorinated (halogenated) material from a PRD release would be required to install and operate an oversized thermal oxidizer equipped with acid gas controls that would be operated on stand-by anytime the facility is in operation; and this operating mode results in the facility also emitting large amounts of secondary emissions such as greenhouse gases, VOCs, NO
                        <E T="52">X</E>
                        , and CO.
                    </P>
                    <P>• PRDs prevent catastrophic breaches of process equipment that could endanger both the lives of plant employees and nearby communities, and result in damage to property; these catastrophic breaches would result in much greater emissions than those resulting from a PRD release. PRDs minimize the loss of process materials to the surrounding environment.</P>
                    <P>Commenters also argued that it is not cost-effective to route all PRDs to control devices. Some commenters pointed out that given that the EPA concluded it is not cost-effective to route all PRDs to control for HON and P&amp;R (and instead proposed a work practice standard for PRDs that vent to the atmosphere), it is unclear how the Agency could presume such a requirement would be cost-effective as BSER and appropriate to establish as an NSPS requirement. Additionally, the commenters asserted that the only analysis the EPA uses to justify the proposed change is the identification of a single lowest achievable emissions rate (LAER) condition in the reasonably available control technology (RACT)/BACT/LAER clearinghouse database. The commenters argued that by equating a single LAER determination (based on the EPA's RACT/BACT/LAER clearinghouse database search regarding ID TX-0813171 for the “Linear Alpha Olefins Plant,” which is operated by INEOS Oligomers USA, LLC) to BSER and not performing any additional analysis, the EPA has ignored the statutory requirements of CAA Section 111(a)(1) in that the Agency did not adequately account for the cost of achieving reductions, nor did the Agency consider non-air quality health and environmental impacts and more specifically, energy requirements.</P>
                    <P>
                        A commenter added that PRDs serve a vitally important role as the last line of defense to protect vessels and 
                        <PRTPAGE P="43013"/>
                        equipment from mechanical failure should an overpressure situation occur; therefore, it is important that they work correctly. The commenter asserted that in the unlikely event that a pressure relief event occurs, it is important to have the opportunity to analyze such situations and implement corrective actions to further minimize the chance that such an event will occur in the future.

                        While commenters state that only one facility was identified as part of the RACT/BACT/LAER clearinghouse database, we note that one additional facility was also identified as having prohibitions on PRDs releasing to the atmosphere and were thus choosing to route those pieces of equipment to an APCD. The Lyondell Chemical Bayport Choate Plant in Harris, TX (permit number 137789) was identified as part of our RACT/BACT/LAER clearinghouse database search, but did not properly state that they were also under restrictions for PRD releases to atmosphere for streams containing more than 1 percent VOC. See the updated document titled

                         which is available in the docket for this rulemaking. Lyondell and the Linear Alpha Olefins Plant were placed under these restrictions by the state of Texas in 2017 and 2015, respectively. In fact, the TCEQ published the document titled 
                        <E T="03">Air Permit Technical Guidance for Chemical Sources Fugitive Guidance</E>
                         in June 2018, which is available in the docket for this rulemaking. Section III of the document states that “the following practices are generally considered to be the minimum for BACT . . . . New relief valves are required to vent to a control device for any potential releases and as a result, any fugitive emissions are reduced. Exceptions may be made if venting relief valve to control will result in a safety concern, but this does not exempt the company from controls such as equipping the valve with a rupture disk and pressure sensing-device.” The EPA maintains that between the guidance provided by the TCEQ and ability of the two identified facilities to meet the requirements, prohibiting PRD releases to atmosphere is adequately demonstrated for purposes of determining BSER.
                    </P>
                    <P>We also disagree with commenters' descriptions of why PRDs releasing to atmosphere are necessary. We note that owners and operators are not obligated to route PRDs to an APCD. In fact, we agree with commenters that PRDs act as a last line of defense in uncommon process conditions. Therefore, the EPA expects that a well-controlled and rigorously designed process will not experience PRD releases regularly, if at all. In those situations, as described by the commenter, where PRD releases are necessary to prevent further catastrophic failure, we agree with the commenter that safety is a priority and PRD releases may be necessary. However, we note that we are not prohibiting the release of PRDs in totality, just to atmosphere, or their use in general and that process conditions leading to catastrophic failure should be well outside regular operating conditions. Therefore, the EPA expects that PRDs used to prevent catastrophic failure can continue to function without reasonable concern for release to atmosphere during regular operating conditions. If the facility is concerned about a PRD releasing to atmosphere during a catastrophic failure event, which should be exceptionally rare to begin with, they may choose to route those emissions to an APCD to avoid incurring a violation. The EPA maintains that releasing uncontrolled volumes of emissions to atmosphere as a result of preventable process upsets is characteristic of a violation.</P>
                    <P>To that point, we are not requiring owners or operators to route PRD releases to an APCD, and there are no cost, non-air quality health, environmental, or energy requirements as a result of this change. The EPA expects no additional equipment will be needed for facilities to meet the finalized provisions given our agreement with commenters that PRD releases are unlikely to occur at all assuming a process is rigorously designed, maintained, and controlled. If the owner or operator chooses to control PRD emissions, it is their responsibility to select whichever control method is most appropriate considering, among other factors, the composition of the release, location of the equipment, and overall safety. We note that facilities with new sources that choose to route PRD emissions to an APCD will have the flexibility in the design and construction phase to select options they consider to be cost-effective and plan based on key criteria like placement of the equipment. For existing sources that trigger the NSPS subpart IIIa, NNNa, or RRRa via a modification or reconstruction, it is the responsibility of the owner or operator to make the determination if retrofitting PRDs to release to an APCD is feasible, cost-effective, and necessary against the potential to incur violations as a result of atmospheric release or if alternative process controls or operational practices are more appropriate. Any cost, non-air quality health, environmental, or energy impacts associated with the owner or operator controlling PRD emissions, including those from halogenated streams as identified by the commenter, were not considered as part of the BSER analysis because they are only incurred at the discretion of an owner or operator if they choose to go beyond the requirements of this rulemaking and pursue control of emissions. For the above reasons, the EPA has met its obligations under CAA section 111(a)(1).</P>
                    <P>We disagree with the commenter that the use of the term “violation” should be replaced with “deviation” in NSPS subparts IIIa (at 40 CFR 60.612a(b)), NNNa (at 40 CFR 60.662a(b)), and RRRa (at 40 CFR 60.702a(b)). We used the term “violation” in the SOCMI NSPS (subparts IIIa, NNNa, and RRRa) to be consistent with the HON standards that also regulate the SOCMI source category.</P>

                         A commenter contended the EPA's BSER analysis was insufficient because it failed to consider key equipment leak control technologies, such as OGI, leak detection sensor networks (LDSNs), and even options that the EPA previously considered in 2007 when developing NSPS subpart VVa. The commenter asserted that the EPA must consider these developments when evaluating and establishing the BSER for new, reconstructed, and modified SOCMI process units. The commenter stated that the EPA's review of the LDAR requirements in NSPS subpart VVa is inconsistent with other reviews of NSPS equipment leak standards. In particular, the commenter noted that in its November 15, 2021 proposal for the 
                        <PRTPAGE P="43014"/>
                        Crude Oil and Natural Gas source category, the EPA evaluated several monitoring techniques, and combinations of techniques, to determine if the BSER for equipment leaks at natural gas processing plants should be revised, including bimonthly and quarterly OGI monitoring in combination with annual EPA Method 21 monitoring at a leak definition of 10,000 ppm, and bimonthly OGI monitoring on all equipment with the potential for VOC emissions. The commenter asserted that the EPA's failure to consider OGI is erroneous considering the EPA has established an Alternative Work Practice at 40 CFR 60.18(g) through (i) that allows sources subject to NSPS subparts VV and VVa to conduct bimonthly OGI monitoring with annual EPA Method 21 surveys at 500 ppm as an alternative to conducting EPA Method 21 monitoring at the leak definitions and frequencies in those subparts. The commenter added that at a minimum, the EPA should evaluate whether this alternative work practice now represents the BSER for NSPS subpart VVb.

                         For the reasons explained below, we find that none of the control options raised in the comment above (
                        <E T="03">i.e.,</E>
                         OGI, LDSN and options considered in the last review) is BSER for equipment leaks from new, modified, and reconstructed SOCMI process units.
                    </P>
                    <P>
                        Regarding OGI, we do not believe it replaces EPA Method 21 as BSER for equipment leaks from SOCMI process units for the following reasons. First, as shown by our equipment leaks regulations for the SOCMI industry since the early 1980s, leaks in the area of 500 to 1000 ppm can be detected using EPA Method 21 and repaired for most equipment in this industry. The EPA acknowledges that OGI is effective at finding large leaks quickly for many compounds, but, while OGI is capable of detecting low-level leaks under certain conditions, it is difficult for a camera operator to find low level-leaks with OGI under the range of conditions that leak surveys are generally conducted, including variable ambient and equipment temperatures, complex backgrounds, and elevated wind speeds. Additionally, the compounds that can be detected by an OGI camera are limited to the compounds that have a peak in the spectral range of the filter on the OGI camera (generally around 3.2-3.4 micron for cameras used to detect hydrocarbons). While many compounds of interest do have a peak in this range, the variety of chemicals found at SOCMI facilities is very broad, and not all of these chemicals can be observed with an OGI camera. For example, ethylene and acetaldehyde have very weak peaks in the spectral range common to OGI camera filters, making it extremely difficult to see these compounds with an OGI camera. For those compounds that can be observed with an OGI camera, the detection range of the camera varies, and some compounds must be emitted in high quantities before being observed. For example, it is expected that twice as much styrene must be emitted as xylene (any isomer) before the emissions are visible with an OGI camera.

                        <FTREF/>
                         For these reasons, the use of OGI is not appropriate for the SOCMI source category.

                             In contrast, the majority of VOC emissions at onshore natural gas processing plants are expected to be comprised of compounds such as butane, pentane, hexane, benzene, toluene, xylenes, and ethylbenzene; the type of compounds emitted are expected to be fairly uniform from all onshore natural gas processing plants. In addition to VOC, leaks at onshore natural gas processing plants generally contain methane. All of these compounds can be identified with an OGI camera. For this reason, OGI is effective in detecting leaks from onshore natural gas processing plants, as the commenter observes, but may not be effective for certain SOCMI process units, where makeup of VOC emissions varies widely across the source category.
                        </P>
                    </FTNT>
                    <P>Regarding LDSNs, which use an array of continuous sensors to find leaks, we agree that these systems can effectively be used to trigger and target EPA Method 21 or OGI monitoring and leak repair, but an effective system depends on the sensitivity of the sensors, the spacing of the sensors, and the trigger used to deploy a ground monitoring crew. It is difficult to develop vendor-agnostic monitoring requirements that can be incorporated generically within a rule, and we do not have the necessary information to do so at this time. While we are continuing to look at how to develop a standardized approach for sensor networks, we are not prepared to include provisions for a continuous sensor network for the SOCMI source category at this time. However, owners or operators can elect to submit a request for an alternative means of emission limitation for using a site-specific sensor network monitoring plan.</P>
                    <P>Finally, the commenter claims that the EPA must evaluate options that we had previously considered while promulgating NSPS subpart VVa in 2007. The EPA does not have information, nor has the commenter provided any, indicating that there has been development since the last review to any such previously rejected option that warrants evaluation in the present review.</P>

                         A commenter stated that the EPA's focus on lowering the leak definition for valves from 500 ppm to 100 ppm is inconsistent with recent EPA focus on targeting large emissions sources, as was done for the oil and gas industry. The commenter stated that rulemaking targeted finding large leaks faster, while in the review for NSPS subpart VVa, the EPA focused on reducing a small population of small leaks by lowering the leak definition for valves from 500 ppm to 100 ppm. The commenter added that the EPA's analysis for NSPS subpart VVa demonstrates this proposed change only results in reducing 0.64 tpy of VOC emissions per affected facility beyond the baseline. The commenter also stated that the facility-level leak inspection data that the EPA has available shows that leaks between 100 ppm and 500 ppm are not very common. The commenter specified that the EPA has access to at least one data set containing leak inspection results for nearly 3,000 components at a chemical manufacturing facility. The commenter added that the average EPA Method 21 reading was over 25,000 ppm, with the minimum reading for valves was 747 ppm and minimum reading for connectors was 1,000 ppm, underscoring the importance of entirely preventing significant leaks (as well as quickly identifying and remediating others). The commenter recommended, in addition to strengthening the standards as it has proposed, that the EPA evaluate the use of additional technology, such as low emission valves and valve packing and connectors less likely to leak, in order to prevent the presence of these large emissions. The commenter concluded that this evaluation would allow the EPA to take action on preventing emissions from occurring at these high rates and potentially result in the determination that a combined program of low-emissions technology with regular EPA Method 21 monitoring and leak repairs is the BSER for SOCMI equipment leaks.

                         The EPA disagrees that the actions taken in this NSPS rulemaking are inconsistent with the actions taken in other recent NSPS rulemakings, specifically the oil and gas NSPS (see 89 FR 16820 (March 8, 2024)). The rulemaking for the oil and gas sector are focused on finding large leaks faster while the leak regulation for SOCMI does not, because there are key differences between the oil and gas and the SOCMI source category. The SOCMI industry has been complying with equipment leak regulations since the early 1980s, and leaks are expected to be 
                        <PRTPAGE P="43015"/>
                        much lower in SOCMI than for the oil and gas industry. As a result, the leak definitions that SOCMI facilities must comply with are already very low, 500 to 1000 ppm for most equipment, and the proposed and final rule lowers leak definitions to 100 ppm for valves to gain even more emissions reductions.
                    </P>
                    <P>Additionally, the data set referenced by the commenter was collected over several years. The chemical facility associated with the data set conducted an OGI survey and then recorded the EPA Method 21 reading for any leaks found by OGI. However, the data set does not include any information related to leaks that could have been found with EPA Method 21 but not OGI. Therefore, the EPA cannot conclude that there are few leaks between 100 ppm and 500 ppm at chemical plants based on this data set. What this data set does demonstrate is that there is no evidence that OGI can find low-level leaks at chemical plants.</P>
                    <P>In the final rule (NSPS subpart VVb), we are not requiring specific types of equipment be used to meet the 100 ppm leak definition for valves. However, in order to meet the 100 ppm leak definition for valves, we anticipate that facilities will need to use low-emission valves or packings. The average cost-effectiveness (with recovery credits) of lowering the leak definition for valves in gas/vapor or light liquid service from 500 ppm to 100 ppm, is $2,780 per ton of VOC reduced, and the EPA estimates this provision could result in reductions of more than 20 tpy of VOC.</P>

                        <E T="03">Comment:</E>
                         A commenter contended that the EPA's proposed definition for capital expenditures in NSPS subpart VVb narrows the reach of modification and would result in the exclusion of certain process units from applicability to the subpart through modification. For NSPS subpart VVb, the commenter opposed the two proposed calculations for “X”. The commenter explained that by proposing a value for “X” to be “2023 minus the year of construction” for sources with a construction date after January 6, 1982 and before January 1, 2023, the EPA has categorically exempted any process unit from ever becoming subject to NSPS subpart VVb through modification if its date of construction is prior to January 6, 1982. The commenter contended that this error must be addressed in the final rule to not create a loophole exempting the oldest of these SOCMI process units from ever becoming subject to NSPS subpart VVb through modification. The commenter suggested revising the value for “X” to mean “2023 minus the year of construction” without the need to bookend this definition with specific dates. The commenter added that the EPA should first evaluate more recent developments on the definition of “capital expenditure” inclusion in the final NSPS subpart VVb. The commenter also opposed the proposed change of “X” for sources constructed in the year 2023 in order for X to not be equal to zero, which results in an equation that cannot be solved. The commenter noted that the EPA has addressed this same issue recently through specific changes to the definition of capital expenditure promulgated in the technical amendments to NSPS subpart OOOOa for equipment leaks at onshore natural gas processing plants. The commenter explained that in those amendments, the EPA revised the equation used to determine “Y” (the percent of replacement costs) to remove the variable “X” (and logarithmic function) and instead the EPA specifically defined “Y” as “the Consumer Price Index (CPI) of the date of construction divided by the most recently available CPI of the date of the project, or “CPIN/CPIPD”. The commenter contended that at a minimum, the EPA must consider this calculation of “Y” when defining “capital expenditure” in NSPS subpart VVb and discuss why the use of the CPI-based ratio is not appropriate for affected facilities before finalizing the proposed definition with the appropriate revisions to close loopholes.

                         We agree with the commenter that in the proposed definition of “capital expenditure” in NSPS subpart VVb, the value of “X” should not be bounded by the NSPS subpart VV date of January 6, 1982. We also agree with the commenter that we should update the definition of “capital expenditure” to use the CPI in the equation for “Y” in NSPS subpart VVb. For the reasons discussed below, the EPA is finalizing the capital expenditure definition in NSPS subpart VVb to state in part that the value of “Y” is calculated using the CPI of the date of original construction of the process unit divided by the most recently available CPI of the date of the project.

                         The EPA developed an alternative method to NSPS subpart A which enabled companies to use replacement cost rather than original cost. In the alternative method, an inflation index is applied to the replacement cost to approximate the original cost basis of the affected facility. The relationship between the replacement and original cost ultimately ended up in the formulas contained in the definitions of “capital expenditure” in NSPS subparts VV and VVa.

                        The formulas for “Y” in the definitions of “capital expenditure” in NSPS subparts VV and VVa were intended to adjust the replacement cost for inflation to approximate the original cost basis; however, the formulas were based on analysis of inflation between the years 1947 and 1982 and do not necessarily reflect current economic conditions. In the 2020 amendments to NSPS subpart OOOOa, which covers the oil and natural gas sector, the EPA determined that using a CPI-based ratio is more appropriate under current economic conditions.

                         Similarly, the EPA has determined the CPI-based ratio better reflects the inflation of chemical process facility construction costs over time and thus is more appropriate for use in determining capital expenditure for the SOCMI source category in NSPS subpart VVb. There are several versions of the CPI published by the U.S. Bureau of Labor Statistics; for simplicity, the EPA is requiring the use of “CPI-U, U.S. city average, all items” (CPI for all urban consumers) for both CPI values.

                         benzene, 1,3-butadiene, ethylene dichloride, vinyl chloride, EtO, and chloroprene) if their site uses, produces, stores, or emits any of them, and conduct root cause analysis and corrective action upon exceeding the annual average concentration action level set forth for each HAP. In the proposal, we identified cost-effective developments only for HON and P&amp;R I heat exchange systems, storage vessels, and process vents, and we proposed to revise the standards for these three emissions sources under the technology review. We did not identify developments in practices, processes, or control technologies (beyond the fenceline monitoring work practice standard) for transfer racks, wastewater, and equipment leaks. Further information regarding the technology review can be found in the proposed rule (88 FR 25080, April 25, 2023) and in the supporting materials in the rulemaking docket at Docket ID No. EPA-HQ-OAR-2022-0730.

                        During the public comment period, we received several comments on our proposed determinations for the technology review. The comments and our specific responses and rationale for our final decisions can be found in section IV.B.3 of this preamble and in the document titled 
                        <E T="03">Summary of Public Comments and Responses for New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         which is available in the docket for this rulemaking. No information presented by commenters has led us to change our proposed determination under CAA section 112(d)(6) for transfer racks, wastewater, and equipment leaks, and we are finalizing our determination that no changes to these standards are warranted. However, based on comments received on the proposed revisions for the Group 1 HON and P&amp;R I storage vessels, we are clarifying that the capacity and MTVP thresholds in the final rule apply to both new and existing sources. In addition, some additional cost information was submitted by commenters on the proposed revisions for HON process vents and P&amp;R I continuous front-end process vents. Based on these comments, we have updated our cost analysis, but continue to believe our revisions for HON process vents and P&amp;R I continuous front-end process vents, as proposed, are still cost-effective. Therefore, for HON process vents and P&amp;R I continuous front-end process vents, we are finalizing, as proposed the: (1) Removal of the TRE concept in its entirety; (2) removal of the 50 ppmv and 0.005 scmm Group 1 process vent thresholds; and (3) redefining of a Group 1 process vent (require control) as any process vent that emits ≥1.0 lb/hr of total organic HAP. Finally, based on comments received on the proposed fenceline monitoring requirements, we have established two action levels in the final rule for chloroprene (
                        <E T="03">i.e.,</E>
                         one action level under CAA section 112(d)(6) for this HAP and another action level under CAA section 112(f)) in lieu of only one action level, as proposed). In addition, based on comments received, we are: (1) Finalizing burden reduction measures to allow owners and operators to skip fenceline measurement periods for specific monitors with a history of measurements that are at or below certain action levels; (2) clarifying that fenceline monitoring is required for owners and operators with affected sources that produce, store, or emit one or more of the target analytes; (3) reducing the requirements for the minimum detection limit of alternative measurement approaches; (4) clarifying how owners and operators establish the monitoring perimeter for both sorbent tubes and canisters; (5) clarifying the calculation of Δc when a site-specific monitoring plan is used to correct monitoring location concentrations due to offsite impacts; (6) changing the required method detection limit for alternative test methods from an order of magnitude below the action level to one-third of the action level; and (4) with the exception of fenceline monitoring of chloroprene at P&amp;R I affected sources producing neoprene, we are changing the compliance date in the final rule to begin fenceline monitoring 2 years (instead of 1 year, as proposed) after the effective date of the final rule. For P&amp;R I affected sources producing neoprene, we have changed the compliance date for fenceline monitoring of chloroprene to begin no later than October 15, 2024, or upon startup, whichever is later, subject to the owner or operator seeking the EPA's authorization of an extension of up to 2 years from July 15, 2024.

                        Under CAA sections 112(d)(2) and (3), we proposed to amend the operating and monitoring requirements for a subset of flares in the SOCMI and P&amp;R I source categories. We proposed at 40 CFR 63.108 (for HON) and 40 CFR 63.508 (for the P&amp;R I NESHAP) to directly apply the petroleum refinery flare rule requirements in 40 CFR part 63, subpart CC, to the HON and P&amp;R I flares with clarifications, including, but not limited to, specifying that several definitions in 40 CFR part 63, subpart CC, that apply to petroleum refinery flares also apply to the flares in the specified subset, adding a definition and requirements for pressure-assisted multi-point flares, and specifying additional requirements when a gas chromatograph or mass spectrometer is used for compositional analysis. Specifically, we proposed to retain the General Provisions requirements of 40 CFR 63.11(b) and 40 CFR 60.18(b) such that HON and P&amp;R I flares operate pilot flame systems continuously and that these flares operate with no visible emissions (except for periods not to 
                        <PRTPAGE P="43017"/>
                        exceed a total of 5 minutes during any 2 consecutive hours) when the flare vent gas flow rate is below the smokeless capacity of the flare. We also proposed to consolidate measures related to flare tip velocity and new operational and monitoring requirements related to the combustion zone gas for HON and P&amp;R I flares. Further, in keeping with the elimination of the SSM exemption, we proposed a work practice standard related to the visible emissions limits during periods when a HON or P&amp;R I flare is operated above its smokeless capacity (
                        <E T="03">e.g.,</E>
                         periods of emergency flaring). We proposed eliminating the cross-references to the General Provisions and instead specifying all operational and monitoring requirements that are intended to apply to HON and P&amp;R I flares in the applicable subparts.

                        For PRD releases, we proposed revisions to the definition of “pressure relief device” for the HON and P&amp;R I NESHAP, a definition of “relief valve” for the HON and P&amp;R I NESHAP, and a definition in the P&amp;R II NESHAP for “pressure relief device.” Under CAA section 112(h), we proposed a work practice standard for PRDs at 40 CFR 63.165(e) (for HON) and 40 CFR 63.502(a)(1) and (a)(2) (which references 40 CFR 63.165, for the P&amp;R I NESHAP) that consists of using at least three prevention measures and performing root cause analysis and corrective action in the event that a PRD does release emissions directly to the atmosphere.
                        <SU>58</SU>
                        <FTREF/>
                         (Examples of prevention measures include flow indicators, level indicators, temperature indicators, pressure indicators, routine inspection and maintenance programs or operator training, inherently safer designs or safety instrumentation systems, deluge systems, and staged relief systems where the initial PRD discharges to a control system.) We proposed that PRDs in EtO service (for HON) and PRDs in chloroprene service (for Neoprene Production processes subject to the P&amp;R I NESHAP) may not vent directly to atmosphere. We also proposed to require that sources monitor PRDs that vent to atmosphere using a system that is capable of identifying and recording the time and duration of each pressure release and of notifying operators that a pressure release has occurred. We proposed at 40 CFR 63.165(e)(4) that PRDs that vent through a closed vent system to a control device or to a process, fuel gas system, or drain system must meet minimum requirements for the applicable control system. In addition, we proposed at 40 CFR 63.165(e)(5) that the following types of PRDs would not be subject to the work practice standard for PRDs that vent to the atmosphere: (1) PRDs in heavy liquid service; (2) PRDs that are designed solely to release due to liquid thermal expansion; (3) PRDs on mobile equipment; and (4) pilot-operated and balanced bellows PRDs if the primary release valve associated with the PRD is vented through a control system. Finally, we proposed at 40 CFR 63.165(e)(8) to require future installation and operation of non-flowing pilot-operated PRDs at all affected sources.

                             The P&amp;R II NESHAP is different from the HON and the P&amp;R I NESHAP because the P&amp;R II NESHAP defines a process vent as a “a point of emission from a unit operation. Typical process vents include condenser vents, vacuum pumps, steam ejectors, and atmospheric vents from reactors and other process vessels.” As such, the P&amp;R II NESHAP does not exclude PRD releases from its production-based emission rate MACT standard.

                         once the vapor space concentration is less than 10 percent of the LEL) and all standing liquid has been removed from the vessel to the extent practicable. In addition, we proposed at 40 CFR 63.119(e)(7) that owners and operators would not be permitted to fill the storage vessel during these periods (such that the vessel would emit HAP to the atmosphere for a limited amount of time due to breathing losses only).

We are also correcting our use of the term “LEL” versus our use of the term “concentration” in 40 CFR 63.119(a)(6) in that “the concentration” of the vapors in storage vessels be less than 10 percent of the LEL and that owners and operators are required to measure “the concentration” of the vapors as a percent of the LEL.

                         Commenters contended that the EPA misuses the term LEL for the maintenance vents and storage vessel degassing provisions. A commenter said that the regulatory language implies that operators have the ability to change the LEL of a vapor by purging or otherwise removing portions of the vapor from equipment. This commenter said that the concentration of a flammable gas or mixture can be lowered (
                        <E T="03">e.g.,</E>
                         by dilution or displacement) to a level that is less than the LEL; thus, they requested that the EPA clarify that concentration of the vapors in equipment be less than 10 percent of the LEL and that facilities are to measure the vapor concentration, not the LEL. Similarly, another commenter requested that the EPA clarify that the concentration of the vapors in equipment and storage vessels be less than 10 percent of the LEL and that facilities are to measure the concentration of the vapors as a percent of the LEL (
                        <E T="03">i.e.,</E>
                         with a hand-held analyzer that reports concentration as a percent of LEL, and not the LEL itself). The commenter suggested that these changes should be made to 40 CFR 63.113(k), 40 CFR 63.118(f) and (m), 40 CFR 63.119(a)(6), 40 CFR 63.486(i), 40 CFR 63.491(h), and 40 CFR 63.492(g). The commenter provided an example saying that in proposed 40 CFR 63.119(a)(6), the second instance of “LEL” should be corrected to read “The owner or operator must determine the concentration using process instrumentation or portable measurement devices . . .”.

                         Several commenters supported the proposed degassing provisions at 40 CFR 63.119(a)(6). However, some commenters requested the EPA also add a concentration limit as an alternative to LEL measurements. The commenters explained that some nonflammable chemicals do not exhibit an LEL, or through the use of an inert blanket, the storage vessel atmosphere would not have an LEL, so owners and operators of storage vessels under these conditions would be unable to comply with the proposed 10 percent LEL threshold. These commenters requested that the EPA allow the storage vessel to be opened after the vapor space organic HAP content has been reduced below 5,000 ppmv, based on the Agency's assertion that this level is equivalent to 10 percent of the LEL. A commenter pointed out that 5,000 ppmv as methane equals 10 percent of the LEL for methane.

                         We agree with commenters that some nonflammable chemicals do not exhibit an LEL, or through the use of an inert blanket, the storage vessel atmosphere would not have an LEL, so owners and operators of storage vessels under these conditions would be unable to comply with the proposed 10 percent LEL threshold. Therefore, we are revising the final rule at 40 CFR 63.119(a)(6) to allow storage vessels to be vented to the atmosphere once a storage vessel degassing organic HAP concentration of 5,000 ppmv as methane is met, or until the vapor space concentration is less than 10 percent of the LEL. We stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023) that we are aware of three regulations regarding storage vessel degassing, two in the state of Texas and the third for the South Coast Air Quality Management District (SCAQMD) in California. Texas has degassing provisions in the TAC and through permit conditions, while Rule 1149 contains the SCAQMD degassing provisions. The TAC requirements are the least stringent and require control of degassing emissions until the vapor space concentration is less than 35,000 ppmv as methane or 50 percent of the LEL. The Texas permit conditions require control of degassing emissions until the vapor space concentration is less than 10 percent of the LEL or until the VOC concentration is less than 10,000 ppmv, and SCAQMD Rule 1149 requires control of degassing emissions until the vapor space concentration is less than 5,000 ppmv as methane. The Texas permit conditions requiring compliance with 10 percent of the LEL and SCAQMD Rule 1149 control requirements are considered equivalent because 5,000 ppmv as methane equals 10 percent of the LEL for methane.

                         A commenter remarked that the work practice standard proposed in 40 CFR 63.119(a)(6) should not only apply to degassing Group 1 storage vessels, but should also be applicable for degassing storage vessels in EtO service. The commenter explained that a storage vessel in EtO service (subject to 40 CFR 63.119(a)(5)) may also need to be degassed during storage vessel shutdown operations, but the way the proposed language is currently written, the storage vessel degassing provisions only apply to storage vessels subject to 40 CFR 63.119(a)(1) and (a)(2). The commenter requested the EPA amend the language in 40 CFR 63.119(a)(6) to include storage vessels in EtO service subject to 40 CFR 63.119(a)(5).

                         It was not our intent to exclude storage vessels in EtO service from the work practice standard in 40 CFR 63.119(a)(6); therefore, we are revising the final rule at 40 CFR 63.119(a)(6) to include storage vessels in EtO service subject to 40 CFR 63.119(a)(5). However, owners and operators are still prohibited from releasing more than 1.0 ton of EtO from all maintenance vents combined in any consecutive 12-month period at 40 CFR 63.113(k)(4). In other words, we still

                        consider degassing a storage vessel a type of maintenance vent. As stated in the final rule (as proposed), an owner or operator may designate any vent stream as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service.

                         A commenter said they supported the proposed work practice standard for periods of planned routine maintenance for storage vessels including the proposed requirement that owners and operators would not be permitted to fill storage vessels during these periods. However, another commenter pointed out that the 240-hour planned routine maintenance provisions at 40 CFR 63.119(f)(3) (for fixed rood roof vessels routed to a fuel gas system or to a process) is inconsistent with the parallel requirement at 40 CFR 63.119(e)(7) for fixed rood roof vessels routed to a control device. The commenter requested the EPA make 40 CFR 63.119(f)(3)(iii) no longer apply on or after the compliance dates specified in 40 CFR 63.100(k)(10) and allow for, in a new paragraph at 40 CFR 63.119(f)(3)(iv), the 240-hour planned routine maintenance provisions for breathing losses for fixed rood roof vessels routed to a fuel gas system or to a process. Citing page 25161 of the preamble to the proposed rule (88 FR 25080, April 25, 2023), the commenter contended that this recommended change for fixed rood roof vessels routed to a fuel gas system or to a process would be consistent with the proposed rule text at 40 CFR 63.119(e)(7) for fixed rood roof vessels routed to a control device. The commenter added that their recommendation is also similar to the approach that the EPA used in the Organic Liquids Distribution MACT (NESHAP subpart EEEE) under 40 CFR 63.2378(d) and (e)(4). The commenter pointed out that the associated recordkeeping requirement in 40 CFR 63.123(h) would also need to be amended slightly to reference the new recommended paragraph at 40 CFR 63.119(f)(3)(iv).

                         We agree with the commenter that the 240-hour planned routine maintenance provisions should apply for breathing losses for fixed rood roof vessels routed to a fuel gas system or to a process given this would parallel the requirement at 40 CFR 63.119(e)(7). Therefore, we are revising the final rule to sunset 40 CFR 63.119(f)(3)(iii) in accordance with the schedule specified in 40 CFR 63.100(k)(10), and to include a new paragraph at § 63.119(f)(3)(iv). We are also revising the final rule at 40 CFR 63.123(h)(3) to reference “§ 63.119(f)(3)(iv)” instead of “§ 63.119(f)(3)(iii).” Additionally, we are revising 40 CFR 63.100(k)(10) to reference “§ 63.119(f)(3)(iv)” as well as the introductory text in 40 CFR 63.119(f)(3) to properly reference the new paragraph at “§ 63.119(f)(3)(iv).” The new paragraph at 40 CFR 63.119(f)(3)(iv) reads: “For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), paragraph (f)(3)(iii) of this section no longer applies. Instead, if you elect to route emissions from storage vessels to a fuel gas system or to a process to comply with the requirements of paragraph (a)(1), (a)(2), or (a)(5) of this section, the fuel gas system or process may only be bypassed when the planned routine maintenance cannot be performed during periods that storage vessel emissions are vented to the fuel gas system or process, and the total aggregate amount of time during which the breathing loss emissions bypass the fuel gas system or process during the calendar year without being routed to a control device must not exceed 240 hours. The level of material in the storage vessel shall not be increased during periods that the fuel gas system or process is bypassed to perform routine maintenance.”

The commenter explained that PRDs associated with larger pressure vessels, such a pressure sphere, are typically designed for very rare scenarios like a fire protection case, and thus venting flammable vapors vertically upward to the atmosphere is a safety feature. The commenter said that many engineering design issues will need to be evaluated before routing PRDs associated with specific pressure vessels to a collection system and control device, such as the potential for back-pressure on the collection header if multiple pressure vessels are included, and the potential for rapidly changing pressures and temperatures that may warrant special designs for the collection header and emission control equipment.</P>

                         It was our intent that if the equipment is not a connector, gas/vapor or light liquid valve, light liquid pump, or PRD in EtO service and the equipment is on a pressure vessel located at a HON or P&amp;R I facility, then that particular equipment is not subject to HON subpart H, but rather the equipment is subject to the pressure vessel requirements we proposed and are finalizing in 40 CFR 63.119(a)(7). Connectors, gas/vapor or light liquid valves, light liquid pumps, and PRDs in EtO service located on a pressure vessel at a HON facility are still subject to HON subpart H; and we are clarifying this in the final rule at 40 CFR 63.119(a)(7). As we stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), the LDAR requirements at 40 CFR 63.119(a)(7) (for HON) and 40 CFR 63.484(t) (for the P&amp;R I NESHAP) are based on similar no-detectable emission requirements required for closed vent systems in most chemical sector NESHAP. The intent of this language is to impose a standard that requires no detectable emissions at all times (
                        <E T="03">i.e.,</E>
                         would be required to meet a leak definition of 500 ppm at each point on the pressure vessel where total organic HAP could potentially be emitted); require initial and annual leak monitoring using EPA Method 21; and require routing organic HAP through a closed vent system to a control device (
                        <E T="03">i.e.,</E>
                         no releases to the atmosphere through a pressure vessel's PRD). Most pressure vessels have relief devices that allow for venting when pressure exceeds setpoints. There are also instances where other components in pressure systems may allow for fugitive releases because of leaks from fittings or cooling systems.

                        We note that our use of the term “deviation” in the preamble to the proposed rule and in 40 CFR 63.119(a)(7) was an error. While the MON rule text uses the MON-defined term “deviation” to describe emissions events, the current HON rule text uses the term “violation.” There are no uses of the term “deviation” to describe an emissions event in the current HON rule text, nor any definition of that term in the HON. Therefore, given that we are building off the existing HON standards, 
                        <PRTPAGE P="43021"/>
                        we believe it is more appropriate to continue to use the term “violation” (in lieu of the undefined term “deviation”) in all of the HON rule text. We have replaced “deviation” with “violation” in the final rule text at 40 CFR 63.119(a)(7).

                         Some commenters contended that the pressure vessel monitoring provisions in 40 CFR 63.119(a)(7) are not feasible for some tanks because the pressure vessel is not accessible to monitoring personnel. The commenter explained that some pressure vessels that store regulated chemicals are located inside containment areas or are partially buried such that monitoring of the vessel surface per EPA Method 21 is not possible. The commenter added that some pressure vessels are double walled tanks designed such that there is an additional external shell outside of the pressure vessel shell (
                        <E T="03">i.e.,</E>
                         a tank within a tank shell). The commenter suggested: (1) Pressure monitoring of the gas space (typically nitrogen) between the pressure vessel wall and the second exterior wall be conducted to detect a potential leak, and if a pressure increase occurs, then the owner or operator should be allowed to follow a work practice that requires that the leak be repaired as soon as practical; and (2) for situations where a pressure vessel is located inside a containment area or partially buried, the owner or operator should only be required to conduct EPA Method 21 monitoring on potential leak sources that are accessible and are not unsafe-to-monitor. The commenter provided suggested rule text edits in order to accommodate this request. Similarly, another commenter suggested the EPA incorporate “unsafe-to-monitor” and “inaccessible” provisions at 40 CFR 63.119(a)(7) similar to those in other sections of NESHAP subpart H and in NESHAP subpart UU because some pressure vessels are located in concrete containment areas, are partially buried, or are otherwise inaccessible for safety purposes. This commenter pointed out that the EPA did not consider costs for facilities to relocate or install new pressure vessels to make them accessible in order to comply with the proposed requirements.

                         A commenter pointed out that the proposed pressure vessel requirements in 40 CFR 63.119(a)(7) appear to apply to any pressure vessel to which NESHAP subpart G applies. The commenter argued that these requirements should only apply to Group 1 storage vessels that are pressure vessels. The commenter explained that with the removal of the pressure vessel exclusion from the storage vessel definition in 40 CFR 63.101 and the addition of the pressure vessel requirements in 40 CFR 63.119(a)(7), the EPA may have inadvertently applied the proposed pressure vessel requirements to all pressure vessels, regardless of whether the pressure vessel is Group 1 or Group 2 or whether the storage vessel is exempt for another reason. The commenter contended that there is no reason that a Group 2 storage vessel (
                        <E T="03">i.e.,</E>
                         one not requiring control) or any other vessel that meets an exclusion in the storage vessel definition should be subject to the proposed operating standards for pressure vessels in 40 CFR 63.119(a)(7).

                         We agree with the commenter that 40 CFR 63.119(a)(7) should only apply to pressure vessels that are considered Group 1 storage vessels (as defined in Table 5 to NESHAP subpart G for existing sources and Table 6 to NESHAP subpart G for new sources). Given that we removed the exemption for “pressure vessels designed to operate in excess of 204.9 kilopascals and without emissions to the atmosphere” from the definition of storage vessel in the final rule, all pressure vessels (not just pressure vessels operating less than or equal to 204.9 kilopascals) are now considered storage vessels in the HON. For this reason, we are clarifying in the final rule that “for each pressure vessel as defined in § 63.101 that is considered a Group 1 storage vessel (as defined in Table 5 of this subpart for existing sources and Table 6 of the subpart for new sources), you must operate and maintain the pressure vessel” as specified in paragraphs 40 CFR 63.119(a)(7)(i) through (v).

                         As we stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023), emissions from surge control vessels and bottoms receivers are characteristic of process vents, not emissions from storage vessels. Our rationale for making this determination is that these vessels operate at process temperatures, not ambient storage temperatures; typically do not undergo level changes that larger storage vessels undergo; and are most often operated under pressure with and without non-condensable gases flowing into and out of them. The size of these vessels is also typically not correlated with emissions, as are storage vessels. The 1.0 lb/hr total organic HAP threshold is based on any continuous emissions that exceed the 1.0 lb/hr emission standard. This is true for all Group 1 process vents. We are finalizing this threshold as proposed given that we found this threshold to be cost-effective for process vents (see our response to comments in section IV.B.3.a.i of this preamble for further details).

                         A commenter requested that the EPA provide the option to use engineering calculations if measurements cannot be made using EPA reference methods to determine whether surge control vessels and bottoms receivers are required to be controlled. The commenter said that the vents from surge control vessels and bottoms receivers are configured more like small tanks than process vents and that these vents could be configured in a variety of ways. The commenter provided an example where the vent may be configured as a pressure/vacuum vent for which venting occurs on an intermittent basis, making it difficult to measure volumetric flow rate since the measurements are not made from a straight discharge pipe where the flow measurement device (

                         The EPA agrees with the commenter that in certain situations, as a result of how surge vessels and bottoms receivers are configured, taking measurements utilizing EPA reference methods may not be possible. As a result, we are finalizing language in the “C” and “Q” terms of the equations at 40 CFR 63.115(g)(3)(ii) and (g)(4)(iv) allowing the use of engineering calculations to determine concentration or flow rate only in situations where measurements cannot be taken with EPA reference methods. We anticipate that in most situations, as evidenced by one facility's responses to the CAA section 114 request, facilities will be able to take measurements from surge vessels and bottoms receivers as if they were process vents. In addition, the EPA

                        notes that while the commenter expressed concern about measuring flow rate, the proposed reference methods (EPA Method 25A or EPA Method 18) are utilized to measure concentration. Given it was the EPA's intent to provide methodology for measuring both flow rate and concentration as part of the proposal, we are adding reference methods for measuring flow rate at 40 CFR 63.115(g)(3)(ii) and 40 CFR 63.115(g)(4)(iv) by adding the following text to the definition of, Q, the flow rate term to remedy the lack of clarity: “determined using Method 2, 2A, 2C, or 2D of 40 CFR part 60, appendix A, as appropriate.”

                    <P>
                        <E T="03">Comment:</E>
                         Several commenters objected to the proposed requirements at 40 CFR 63.119(b)(7) that would require owners and operators that use sweep, purge, or inert blankets between the IFR and fixed roof of storage vessels to route emissions through a closed vent system and control device. Some commenters explained that the EPA did not consider the cost-effectiveness of controls under CAA section 112(d)(2) when considering this proposal. A commenter said that most IFR storage vessels are equipped with a sweep, purge, or blanket and the proposed requirements would render these storage vessels obsolete, given that facilities could remove the IFR and route all emissions to a control device while remaining in compliance with the rule. The commenter acknowledged that a continuous purge of an inert blanket will result in higher emissions from an IFR than no purge; however, the commenter added that IFR storage vessels are normally not designed to hold pressure, and the space between the IFR and the fixed roof must vent somewhere when the vessel is being filled, and conversely there must be a mechanism to avoid a vacuum in the vessel when the vessel is being emptied to prevent a vessel failure. To support their objection to the proposed requirements at 40 CFR 63.119(b)(7), the commenter provided a cost analysis for this level of control that resulted in emissions reductions of 0.1 lb/hr of HAP per vessel, which they estimated would cost $190,000/yr to control and would not be cost-effective. Other commenters agreed with this cost analysis and stated the cost would not justify the additional amount of emissions reductions. These commenters suggested the EPA revise their analysis, and if the proposed level of control was found to be cost-effective, the commenters requested that the EPA also consider the secondary emissions (
                        <E T="03">i.e.,</E>

                        ) that would result from the additional fuel required to treat a stream largely comprised of inert gas. A commenter said that adding downstream abatement measures to IFR vessels will require significant structural foundations to and from, or between, as applicable, emission sources, air abatement controls, utilities, and control systems for tanks already located at relatively remote locations, making them more costly than otherwise similar ancillary equipment at locations closer to manufacturing operations. Finally, the commenter requested that the EPA clarify whether the proposed requirements apply to all vessels with a sweep, purge, or blanket, or only a subset, as vessels with IFRs are generally not designed to hold pressure, and would need to vent to avoid negative pressure. The commenter added that the space between the IFR and the fixed roof must vent somewhere when the vessel is being filled and conversely there must be a mechanism to avoid a vacuum in the tank when the vessel is being emptied to prevent a tank failure.

                         Installing a floating roof minimizes evaporative losses of the stored liquid. Both contact and noncontact decks incorporate rim seals and deck fittings to reduce evaporative loss of the stored liquid. Evaporative losses from floating roofs may come from deck fittings, nonwelded deck seams, and the annular space between the deck and vessel wall. In addition, IFRs are freely vented by circulation vents at the top of the fixed roof. The vents minimize the possibility of organic vapor accumulation in the tank vapor space in concentrations approaching the flammable range. An IFR vessel not freely vented is considered an IFR vessel with a closed vent system. Sections 7.1.3 and 7.1.3.8.2 of EPA's AP-42, Fifth Edition,

                        The HON allows owners or operators to choose from different options to control emissions from storage vessels and comply with the MACT standards (
                        <E T="03">i.e.,</E>
                         owners and operators can use a closed vent system and control device to reduce inlet emissions of total organic HAP by 95 percent or greater, or reduce organic HAP by utilizing a fixed roof and IFR, an EFR, an EFR converted to an IFR, route the emissions to a process or a fuel gas system, or vapor balance). As such, the use of a floating roof that meets the requirements in 40 CFR 63.119(b) is one of the control options owners or operators may choose for control of emissions during normal storage vessel operations.
                    </P>
                    <P>Section 7.1 of the EPA's AP-42, Fifth Edition suggests a default reduction of 5 percent on total estimated emissions to account for the use of closed vents on an IFR. This recommendation is based on API Technical Report 2569 which we have determined assumes gas blanketing or another method is used (for IFR vessels vented only through a pressure/vacuum vent in the fixed roof) to prevent the development of a combustible gas mixture within the vessel. However, we believe that neither AP-42 or API Technical Report 2569 addresses the scenario where the use of a sweep, purge, or inert blanket between the IFR and fixed roof would cause a pressure/vacuum vent to remain continuously open to the atmosphere; and this scenario was certainly not considered during the development of the HON MACT standard for storage vessels. A pressure/vacuum vent that remains continuously open to the atmosphere while using a sweep, purge, or inert blanket between the IFR and fixed roof is effectively a continuous process vent.</P>

                        We note that in a 2021 site-specific monitoring plan submitted to the EPA for approval for fenceline monitoring at a refinery located in Corpus Christi, Texas (see 
                        <E T="03">Site-Specific Benzene Fenceline Monitoring Plan Corpus Christi Refinery East Plant Revision 2,</E>
                         CITGO Petroleum Corporation, December 1, 2021, which is available in the docket for this rulemaking), the company identified a slow rise in benzene concentration over the course of about a year. During this period, the company said they investigated the area for potential sources of the elevated benzene concentrations and completed a root cause analysis that identified a HON IFR storage vessel as the primary cause. The particular HON IFR storage vessel uses a nitrogen blanket between the IFR and the fixed roof to protect the storage contents from being contaminated with oxygen. During the investigation, the company found that the nitrogen regulator was malfunctioning which increased the pressure within the tank and ultimately released emissions to the atmosphere 
                        <PRTPAGE P="43023"/>
                        (due to a small operating set point range for the nitrogen regulator and relief vent). Ultimately, the company addressed the elevated benzene concentrations by replacing the nitrogen regulator on the HON IFR storage vessel and routing the emissions to a liquid scrubber, carbon absorption system, and a vapor combustion unit. We have also seen other companies acknowledge similar fenceline monitoring scenarios where HON IFR storage vessels (with sweep, purge, or inert blanket between the IFR and the fixed roof of the vessel) are contributing to elevated benzene concentrations (see 
                        <E T="03">Site Specific Monitoring Plan, ExxonMobil Baton Rouge Refinery,</E>

                    </P>
                    <P>As such, we believe the use of a sweep, purge, or inert blanket between the IFR and fixed roof that would cause a pressure/vacuum vent to remain continuously open to the atmosphere is a regulatory gap. Given that continuous sweeping, purging, or blanketing between the IFR and the fixed roof of the vessel effectively creates a continuous process vent, we proposed to address this regulatory gap pursuant to CAA section 112(d)(2) and (3), by requiring owners and operators that use a sweep, purge, or inert blanket between the IFR and fixed roof of a storage vessel to route emissions through a closed vent system and control device (see 40 CFR 63.119(b)(7)). In light of the comments received, we are clarifying in the final rule at 40 CFR 63.119(b)(7) that owners and operators must route emissions through a closed vent system and control device if they use a continuous sweep, purge, or inert blanket between the IFR and fixed roof that causes a pressure/vacuum vent to remain continuously open to the atmosphere where uncontrolled emissions are greater than or equal to 1.0 lb/hr of total organic HAP. This threshold is consistent with the definition we proposed and are finalizing for Group 1 process vents. These requirements are consistent with CAA section 112(d) controls and reflect the MACT floor. With regard to cost, the MACT floor is the minimum control level allowed for MACT standards promulgated under CAA section 112(d)(3), not CAA section 112(d)(2), and may not be based on cost considerations.</P>

                        We evaluated all of the comments on the EPA's proposed amendments to revisions for flares used as APCDs, clarifications for periods of SSM and bypasses, including PRDs, bypass lines on closed vent systems, and planned routine maintenance of storage vessels, and requirements for maintenance vents and equipment openings, storage vessel degassing, emission limits for dioxins and furans, pressure vessels, surge control vessels and bottoms receivers, sweep, purge, and inert blankets from IFRs, transfer operations (for HON), heat exchange systems (for the P&amp;R II NESHAP), and equipment leaks (for the P&amp;R II NESHAP). For the reasons explained in section III.D of the proposal preamble (88 FR 25080, April 25, 2023), we find that the flare amendments are needed to ensure that flares used as APCDs achieve the required level of MACT control and meet 98-percent destruction efficiency at all times as well as to ensure that CAA section 112 standards apply at all times. Similarly, the clarifications for periods of SSM and bypasses, including PRDs, bypass lines on closed vent systems, and planned routine maintenance of storage vessels, and requirements for maintenance vents and equipment openings, storage vessel degassing, emission limits for dioxins and furans, pressure vessels, surge control vessels and bottoms receivers, sweep, purge, and inert blankets from IFRs, transfer operations (for HON), heat exchange systems (for the P&amp;R II NESHAP), and equipment leaks (for the P&amp;R II NESHAP) are needed to be consistent with

Some of these commenters said that according to facilities' self-reported data, SSM emissions are often of the same magnitude as the facilities' reported routine emissions, and SSM emissions tend to spike during severe weather events. A commenter pointed out specific reportable quantities of emissions resulting from unplanned emissions events and planned SSM activities via the State of Texas Environmental Electronic Reporting System (STEERS). The commenters argued that with the properly installed and executed emission control systems, fail safes, backup power, maintenance procedures and risk management plans, emissions associated with both extreme weather and routine operations are preventable and should not be exempted from legally permitted emission limits. The commenters argued that the EPA erroneously concludes that the malfunction loopholes at 40 CFR 63.165(e)(3)(v)(B) and (C) and smoking flares at 40 CFR 63.670(o)(7)(ii) and (iv) are reasonable.</P>

                    <P>• the PRD and smoking flare loopholes (at 40 CFR 63.165(e)(3)(v)(B) and (C) and 40 CFR 63.670(o)(7)(ii) and (iv)) are just another variation on the original malfunction exemption and the affirmative defense to civil penalties, each of which the D.C. Circuit has found unlawful under CAA sections 302(k), 304, 113, 112(d), and 112(f).</P>
                    <P>• the EPA's creation of these exemptions (at 40 CFR 63.165(e)(3)(v)(B) and (C) and 40 CFR 63.670(o)(7)(ii) and (iv)) runs directly contrary to its own recognition in prior administrative practice citing the EPA's brief defending the boiler rule.</P>
                    <P>
                        • even though the EPA included reporting and root cause analysis requirements, the work practice standards still constitute a total exemption from the core requirements for PRDs and flares during malfunctions of unlimited HAP release in amount and duration (in other words, there is no limit on the amount of HAPs emitted that applies during those releases allowed at 40 CFR 63.165(e)(3)(v)(B) and (C) and 40 CFR 63.670(o)(7)(ii) and (iv)); and the EPA attempted to justify its original SSM exemption on similar grounds in

                    <P>• the EPA has required and recognized the necessity of control for HON, P&amp;R I, and MON PRDs in EtO service, P&amp;R I PRDs in chloroprene service, and all Organic Liquid Distribution and P&amp;R II PRDs, but has not applied equal controls to other PRDs or to flares above their smokeless capacity. This underscores the unlawfulness of the exemptions (at 40 CFR 63.165(e)(3)(v)(B) and (C) and 40 CFR 63.670(o)(7)(ii) and (iv)), and treating these releases so differently is arbitrary and capricious.</P>

                        Specifically, with regards to 40 CFR 63.670(o)(7)(ii) and (iv), several commenters said that smoking flares produce significant amounts of ‘soot’; and beyond the health risks of particulate matter, smoking flares increase production of ozone, especially in the presence of greater environmental heat. A supporter of 40 CFR 63.670(o)(7)(ii) and (iv) reiterated that the provisions are necessary because the EPA is removing the SSM provisions. The commenter also said that they supported the proposal to operate in accordance with a flare management plan during periods when the flow to

                        the flare exceeds the smokeless capacity of the flare.

                    <P>Other supporters of 40 CFR 63.165(e)(3)(v)(B) and (C) argued that there should be no limit on the number of PRD releases allowed to the atmosphere. A commenter cited MACT standards, such as LDAR programs, and contended that generally these programs do not limit the number of leaks allowed. The commenter also added that if the EPA proceeded with the proposed work practice standard, then they agreed with the EPA's decision to allow one or two releases under the conditions set forth in 40 CFR 63.165(e)(3)(v)(B) and (C). Commenters also requested that the EPA clarify that the start date for the initial three-year period for the limit on PRD releases to the atmosphere is the first full calendar year after the compliance date for the PRD work practice standard. The commenters further requested that the EPA include provisions that would not count the second event from the same equipment and same root cause within a 3-year period as a deviation where a) the root cause investigation from the first incident is not yet complete; and/or b) where the corrective action resulting from the root cause investigation requires a capital expenditure and such has been initiated and is being timely pursued.</P>

                        <E T="03">Response:</E>
                         The EPA acknowledges the commenters' support for removing the SSM exemptions in the rules. As we explained in the preamble to the proposed rule (88 FR 25080, April 25, 2023), in 
                        <E T="03">Sierra Club</E>
                         v. 
                        <E T="03">EPA,</E>
                         551 F.3d 1019 (D.C. Cir. 2008), the Court determined that the SSM exemption violates the CAA. Specifically, the court vacated the SSM exemption contained in 40 CFR 63.6(f)(1) and 40 CFR 63.6(h)(1), holding that under CAA section 302(k), emissions standards or limitations must be continuous in nature and that the SSM exemption violates the CAA's requirement that some section 112 standards apply continuously. With the issuance of the mandate in 
                        <E T="03">Sierra Club</E>
                         v. 
                        <E T="03">EPA,</E>
                         the exemption language in 63.6(f)(1) and (h)(1) is null and void and any cross reference to those provisions has no effect.
                    </P>
                    <P>However, we disagree with other commenters suggesting that the EPA created loopholes for releases from PRDs at 40 CFR 63.165(e)(3)(v)(B) and (C) and smoking flares at 40 CFR 63.670(o)(7)(ii) and (iv) during malfunctions. At proposal, the EPA explained that “[a]lthough no statutory language compels the EPA to set standards for malfunctions, the EPA has the discretion to do so where feasible.” (88 FR 25167). We further explained that “[t]he EPA will consider whether circumstances warrant setting work practice standards for a particular type of malfunction in the SOCMI, P&amp;R I, and P&amp;R II source categories, and, if so, whether the EPA has sufficient information to identify the relevant best performing sources and establish a standard for such malfunctions.” (88 FR 25168.) It is very difficult to guard perfectly against acts of God and acts of terrorism. The EPA does not believe it can develop measures that would effectively limit emissions during all such acts.</P>
                    <P>
                        Regardless, the PRD work practice standard requires redundant prevention measures, which are designed to limit the duration and quantity of releases from all atmospheric PRDs regardless of the cause. Flares are required to comply with the requirements for a continuously lit pilot flame and combustion efficiency standards (
                        <E T="03">i.e.,</E>
                         limits on the NHVcz) at all times, including during periods of emergency flaring caused by a 
                        <E T="03">force majeure</E>
                         event. These requirements apply at all times; thus, the final work practice standards do have requirements that apply to PRDs and flares at all times and they are not contrary to the CAA requirements in CAA section 112. In addition, the work practice standard for PRDs requires installation and operation of continuous monitoring device(s) to identify when a PRD release has occurred. We also note that facilities are required to initiate a root cause analysis to assess the cause of a release, including releases determined to be caused by a 
                        <E T="03">force majeure</E>
                         event. The count of events at 40 CFR 63.165(e)(3)(v)(B) and (C) and smoking flares at 40 CFR 63.670(o)(7)(ii) and (iv) includes events for which the root cause is determined to be 
                        <E T="03">force majeure.</E>
                         In other words, there is no categorization or interpretation related to the root cause of the event; and the corrective action component of the work practice standards applies to all events regardless of the root cause and all events would count towards the violation criteria set forth in the standard. We note that further comments on the concept of “
                        <E T="03">force majeure</E>
                        ” and our responses to these comments can be found in section 7.2 of the document titled

                    </P>
                    <P>We disagree with the comments regarding the exemptions being arbitrary and capricious. We modeled the applicability of the PRD provisions after the SCAQMD rule, based on a MACT floor analysis and considering the appropriate requirements for these types of PRDs. With regard to PRDs in EtO or chloroprene service, we stated in the preamble to the proposed rule (88 FR 25080, April 25, 2023) that any release event from a PRD in EtO (from the SOCMI source category) or chloroprene service (from the Neoprene Production source category) is a violation of the standard in order to help reduce risk from these source categories to an acceptable level.</P>
                    <P>
                        With regard to the request that we clarify the start date for the work practice standards, the regulatory text at 40 CFR 63.165(e)(3)(iv), 40 CFR 63.165(e)(3)(v)(B) and (C) (for PRDs) and at 40 CFR 63.670(o)(7(ii) and (iv) (for smoking flares), states that the time period is based on a 3-calendar-year period. We consider 2023 to be 1 calendar year. A 3-calendar-year period in 2023 would include events that occurred in 2021, 2022, and 2023. It is a rolling average to the extent that, in 2024, one would consider events that occurred in 2022, 2023, and 2024. As indicated in 40 CFR 63.182(d)(2)(xviii)(C), each pressure release to the atmosphere, including the duration of the release, the estimated quantity of each organic HAP released, and the results of the root cause analysis and corrective action analysis completed during the reporting period must be included as part of the reporting obligation. We disagree with the comment regarding meeting certain criteria and not counting the second event from the same equipment and same root cause as a deviation. First, we want to clarify that we mean violation, not deviation. Our use of the term “deviation” in the preamble to the proposed rule was an error (however, we did use “violation” in the proposed rule text in 40 CFR 63.165). While the MON rule text uses the MON-defined term “deviation” to describe emissions events, the current (and proposed) HON rule text uses the term “violation.” There are no uses of the term “deviation” to describe an emissions event in the current HON rule text, nor any definition in the HON of that term. Therefore, given that we are building off the existing HON standards, we believe it is more appropriate to continue to use the term “violation” (in lieu of the undefined “deviation”) in all of the HON rule text. Second, at proposal, we 
                        <PRTPAGE P="43026"/>
                        explained that two release events with the same root cause from a single PRD in a 3-year period is a violation from the MACT standard. 88 FR 25157. The commenter requested that if a corrective action has not been implemented to resolve an issue, then related PRD releases should not be counted towards the violation; however, this result is exactly what the EPA wants to prevent by having a lower release threshold for violations when a PRD release results from the same root cause.

                        We evaluated all of the comments on the EPA's proposed amendments to the SSM provisions. For the reasons explained in the proposed rule (88 FR 25080, April 25, 2023), we determined that these amendments, which remove and revise provisions related to SSM, are necessary to be consistent with the requirement that the standards apply at all times. More information concerning the amendments we are finalizing for SSM is in the preamble to the proposed rule (88 FR 25080, April 25, 2023) and in the comments and our specific responses to the comments in the document titled

                    <P>
                        We are finalizing the changes described in section IV.E.1 of this preamble as proposed, except for certain changes related to the “capital expenditure” definition in NSPS subpart VVa. For NSPS subpart VVa, we are finalizing the “capital expenditure” definition in NSPS subpart VVa in place during the stay of the definition for facilities that underwent a physical or operational change prior to November 16, 2007. We recognize, depending on the year a modification took place, this definition may potentially leave an indeterminant outcome (
                        <E T="03">e.g.,</E>
                         log (X) where X is a negative value) for calculation of the adjusted annual asset guideline repair allowance. However, to the extent there were sources that encountered this scenario (where a physical or operational change between November 7, 2006 and November 16, 2007 triggered an evaluation of whether the capital expenditure was above the threshold to be considered a modification), the NSPS subpart VVa applicability determination would have been resolved a long time ago; thus, finalizing the same definition as applied during the stay would avoid upending any long-standing determinations. Therefore, in the final rule, we are finalizing the definition that was in place during the stay, which include correcting several errors made in our proposed definition and noted by commenters. Specifically, the proposed definition erroneously attached the value of “X” in the percent Y equation to the date of construction, reconstruction, and modification (as opposed to date of physical or operational change); in the final rule, we have replaced that phrasing with a reference to physical and operation change. In addition, we revised the value of “X” from “1982” to “1982 minus the year of construction.” Accordingly, in the final rule, we are revising the “capital expenditure” definition in NSPS subpart VVa at 40 CFR 60.481a such that for owners or operators that made a physical or operational change to their existing facility prior to November 16, 2007, the percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where the value of “X” is 1982 minus the year of construction; for owners or operators that made a physical or operational change to their existing facility on or after November 16, 2007, the percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where the value of “X” is 2006 minus the year of construction.

                         A commenter objected to the EPA removing the connector monitoring provisions from NSPS subpart VVa and only proposing them in NSPS subpart VVb. The commenter contended that the EPA did not provide sufficient justification for this change, given that the EPA's rationale was only that they agreed with Petitioners that it had not included those requirements in the November 7, 2006, proposal (72 FR 64860) but then established connector monitoring requirements in the November 16, 2007 final rule without notice and an opportunity to comment. The commenter added that the EPA must also justify why it is not appropriate to lift the stay and require connector monitoring at sources subject to NSPS subpart VVa from this point forward. The commenter listed several issues with the EPA's decision:
                    </P>
                    <P>• The EPA must propose and provide opportunity for comment on requiring connector monitoring at sources subject to NSPS subpart VVa. The basis of the reconsideration was a lack of notice and comment, and the EPA is currently in the position to provide an opportunity for comment on those requirements yet fails to do so with no explanation.</P>
                    <P>• The EPA must justify why additional emissions reductions for sources subject to NSPS subpart VVa are no longer appropriate before simply removing the requirements in their entirety. The EPA found connector monitoring as the “best system of emission reduction” in the November 16, 2007, preamble, and the EPA has not explained why that determination was inappropriate or no longer valid. In EPA's analysis supporting the final NSPS subpart VVa, it found that the promulgated connector monitoring requirements were: (1) Common practice at many chemical manufacturing facilities, including through regulations such as HON, MON, Ethylene MACT, and the Generic MACT (40 CFR 63, subpart UU), (2) resulted in greater emission reductions (230 tpy VOC) than the changes the EPA implemented for pumps and valves (94 tpy VOC) in NSPS subpart VVa, and (3) were achieved at a cost $2,500 per ton of VOC reduced.</P>
                    <P>• The EPA must justify why the same requirements it is proposing to remove from NSPS subpart VVa are only appropriate for NSPS subpart VVb.</P>
                    <P>The commenter asserted that the EPA can and must lift the stay as it relates to connector monitoring in 40 CFR 60.482-11a and require compliance with that section from that date forward in order to ensure the critical (and cost-effective) environmental protections are implemented, while avoiding concerns of retroactive application of standards. The EPA could do this through providing language that the standards were stayed from June 2, 2008, until the date of the final rule, but are in effect moving forward.</P>
                    <P>
                        <E T="03">Response:</E>
                         As previously discussed in the preamble to the proposed rule (88 FR 25080, April 25, 2023), we proposed to remove the connector monitoring requirements in NSPS subpart VVa that have been stayed since 2008. The EPA disagrees with the comment that, having granted reconsideration of these requirements because they were finalized without proposal and an opportunity for comment, the EPA must now propose to remove the stay and provide the public an opportunity to comment on the connector requirements. While CAA section 307(d)(7)(B) requires that the EPA grant reconsideration in this situation (where the grounds for objecting to the standard arose after the period for public comment, in this case when the final rule was promulgated), nothing in CAA section 307(d)(7)(B) or elsewhere in the CAA dictates what actions the EPA must take in a reconsideration proceeding, much less requiring that the EPA propose the connector requirements for comment; nor has the commenter cited any legal authority requiring such action from the EPA in an administrative reconsideration proceeding under CAA section 307(d)(7)(B).
                    </P>
                    <P>
                        In its reconsideration of the connector requirements in NSPS subpart VVa, the EPA took into account that these requirements have been stayed since June 2008, over 15 years ago and shortly after the promulgation of NSPS subpart VVa in November 2007. In light of the fact that the connector requirements have not been part of NSPS subpart VVa's long implementation history, the EPA does not think it is appropriate to amend NSPS subpart VVa now to add a new requirement for new equipment (
                        <E T="03">i.e.,</E>
                         connectors) for sources constructed, reconstructed or modified between November 7, 2006 and April 26, 2023, which are existing sources for purposes of the newly promulgated NSPS subpart VVb. The EPA believes that standards for previously unregulated sources such as the connectors are better suited moving forward for new and modified sources under NSPS subpart VVb. For the reasons stated above, the EPA is finalizing the removal of the connector requirements in NSPS subpart VVa, as proposed.

                        <E T="03">Comment:</E>
                         Commenters requested the EPA correct the formula for calculating the value of “X” in the definition of “Capital Expenditure” in the proposed NSPS subpart VVa. A commenter explained that the EPA proposed a value of “1982” for “X” for owners or operators “that start a new, reconstructed, or modified affected source prior to November 16, 2007.” The commenter contended that this results in a negative value for “Y” (that is, −0.89, or 1.0-0.575log(1982)), being effectively an indeterminant outcome for calculation of the adjusted annual asset guideline repair allowance. Another commenter recommended that the EPA revise “X” from “1982” to “1982—the year of construction” for owners or operators “that start a new, reconstructed, or modified affected source prior to November 16, 2007.”
                    </P>
                    <P>
                        Another commenter contended that the EPA's proposed definition for capital expenditures in NSPS subpart VVa narrows the reach of modification and would result in the exclusion of certain process units from applicability to the subpart through modification. For NSPS subpart VVa, the commenter contended the EPA has made significant errors in defining how sources would determine if modification has occurred and went beyond addressing the issues raised by the petitioners requesting reconsideration of the capital expenditure definition. The commenter asserted that it is inappropriate to include a definition for modification related to a date of construction, reconstruction, or modification that operates apart from the applicability of the individual subpart. The commenter explained that a source that is constructed or reconstructed after the applicability date of the subpart (November 7, 2006, for NSPS subpart 
                        <PRTPAGE P="43028"/>
                        VVa) is automatically subject to the standards of that subpart and modification has no relevance unless a subpart with a later applicability date is promulgated. The commenter added that a source is not defined as modified unless it undergoes a physical or operational change that results in an increase in emissions. The commenter contended that a definition of capital expenditure that is reliant on the dates of “construction, reconstruction, or modification” is not relevant to and has no bearing on whether a source has been modified. The commenter concluded that the EPA must redefine capital expenditure without specifying construction, reconstruction, or modification dates. The commenter recommended that the EPA should seek to address the definition of capital expenditure as it applies to the subset of physical and operational changes that occurred specifically between November 7, 2006, and November 16, 2007. The commenter added that for those sources that would have utilized the capital expenditure equation in NSPS subpart VV, it is appropriate to define the value of “X” as “1982 minus the year of construction” or simply cross-reference the capital expenditure definition at 40 CFR 60.481. The commenter stated that the definition of capital expenditure as it relates to physical and operational changes that take place after November 16, 2007 (the promulgation date of NSPS subpart VVa), was not under reconsideration and should remain as promulgated such that the EPA define “X” based on the dates of “physical or operational changes” regardless of the date of construction, reconstruction, or modification, and specifically, for physical or operational changes that take place after November 16, 2007, “X” should remain defined as “2006 minus the year of construction.”
                    </P>
                    <P>
                        <E T="03">Response:</E>
                         We agree that errors were made in the proposed “capital expenditure” definition in NSPS subpart VVa. The proposed definition, in relevant part, stated that
                    </P>
                    <P>“(2) The percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where X is:</P>
                    <P>(i) 2006 minus the year of construction for owners or operators that start a new, reconstructed, or modified affected source on or after November 16, 2007, or</P>
                    <P>(ii) 1982 for owners or operators that start a new, reconstructed, or modified affected source prior to November 16, 2007;”</P>
                    <P>
                        We agree with the comment that the proposed definition erroneously relies on a sources' construction, reconstruction, or modification date for calculating capital expenditure to determine whether modification has been triggered for that source. Sources constructed, modified, or reconstructed after November 7, 2006, are affected facilities under NSPS subpart VVa (
                        <E T="03">i.e.,</E>
                         they are subject to the standards of NSPS subpart VVa); whether any such NSPS subpart VVa affected facility has subsequently incurred capital expenditure that would constitute “modification” is irrelevant as the only purpose for that capital expenditure calculation is to determine NSPS subpart VVa applicability, which we already know it does. The commenter also correctly notes that modification is determined by whether there is a physical or operational change that results in an increase in emissions. See 40 CFR 60.2 and CAA section 111(a)(4). For the reasons stated above, in the final rule, we have revised the proposed “capital expenditure” definition by referencing the date of a physical or operational change to a source instead its construction, modification and reconstruction date.
                    </P>
                    <P>Regarding the value of “X” for owners and operators that made a physical or operation change to their existing facility prior to November 16, 2007, commenters are correct that the value of “X” being 1982 results in a negative value for the variable “Y”; the proposed regulation edits (see Docket Item No. EPA-HQ-OAR-2022-0730-0067) mistakenly required the value of “X” be 1982 instead of the intended equation. The intended equation for “X” was 1982 minus the year of construction; this equation was described in the proposal preamble (88 FR 25172) and aligns with the commenters' recommendation, which we acknowledge could still result in a nonsensical value for the variable “Y” for certain scenarios. However, the impact of this issue is unclear, as it would affect only sources that made a physical or operational change within the relevant one-year period (after November 7, 2006 but before November 16, 2007). To the extent there were such sources, we believe that they had long ago found ways to resolve the issue and determine NSPS subpart VVa applicability, perhaps in consultation with the relevant EPA region or delegated State agencies; thus, finalizing the same definition as that which was in effect during the relevant one-year period would avoid upending any such long-standing resolutions or determinations by owners/operators and/or EPA or delegated State agencies.</P>
                    <P>For the reasons described above, we are finalizing the equation for calculating the variable “Y” in the definition of “capital expenditure” in NSPS subpart VVa as follows:</P>
                    <P>(2) The percent Y is determined from the following equation: Y = 1.0 − 0.575 log X, where X is:</P>
                    <P>(i) 2006 minus the year of construction if the physical or operational change to the existing facility was on or after November 16, 2007, or</P>
                    <P>(ii) 1982 minus the year of construction if the physical or operational change to the existing facility was prior to November 16, 2007.</P>

                    <P>
                        We proposed a requirement that owners or operators submit electronic copies of certain required performance test reports, flare management plans, and periodic reports (including fenceline monitoring reports for HON and the P&amp;R I NESHAP) through the EPA's CDX using the CEDRI (at 40 CFR 63.108(e), 40 CFR 63.152(c) and (h), and 40 CFR 63.182(d) and (e) (for HON), 40 CFR 63.506(e)(6), and (i)(3) (for the P&amp;R I NESHAP), and 40 CFR 63.528(a) and (d) (for the P&amp;R II NESHAP), 40 CFR 60.486(l), and 60.487(a) and (g) through (i) (for NSPS subpart VV), 40 CFR

                        60.486a(l), and 60.487a(a) and (g) through (i) (for NSPS subpart VVa), 40 CFR 60.486b(l), and 60.487b(a) and (g) through (i) (for NSPS subpart VVb), 40 CFR 60.615(b), (j), (k), and (m) through (o) (for NSPS subpart III), 40 CFR 60.615a(b), (h) through (l), and (n), and 40 CFR 619a(e) (for NSPS subpart IIIa), 40 CFR 60.665(b), (l), (m), and (q) through (s) (for NSPS subpart NNN), 40 CFR 60.665a(b), (h), (k) through (n), and (p), and 40 CFR 669a(e) (for NSPS subpart NNNa), 40 CFR 60.705(b), (l), (m), and (u) through (w) (for NSPS subpart RRR), and 40 CFR 60.705a(b), (k) through (o), and (v), and 40 CFR 709a(e) (for NSPS subpart RRRa)). We also proposed two narrow circumstances in which owners or operators may seek extensions to the deadline if they are prevented from reporting by conditions outside of their control within five business days of the reporting deadline. We proposed that an extension may be warranted due to outages of the EPA's CDX or CEDRI that precludes an owner or operator from accessing the system and submitting required reports. We also proposed that an extension may be warranted due to a

                        In addition, we proposed the restructuring of all HON definitions from NESHAP subparts G and H (
                        <E T="03">i.e.,</E>
                         40 CFR 63.111 and 40 CFR 63.161, respectively) into the definition section of NESHAP subpart F (

                         40 CFR 63.101); and we proposed to consolidate differences between certain definitions in these subparts.

                    <P>We proposed adding monitoring requirements at 40 CFR 63.114(a)(5)(v), 40 CFR 63.120(d)(1)(iii), 40 CFR 63.127(b)(4), and 40 CFR 63.139(d)(5) (for HON), and 40 CFR 63.484(t), 40 CFR 63.485(x), and 40 CFR 63.489(b)(10) (for the P&amp;R I NESHAP) for owners or operators using adsorbers that cannot be regenerated and regenerative adsorbers that are regenerated offsite. We also proposed that owners or operators of this type of APCD use dual (two or more) adsorbent beds in series and conduct monitoring of HAP or TOC on the outlet of the first adsorber bed in series using a sample port and a portable analyzer or chromatographic analysis.</P>
                    <P>In addition, we proposed several corrections to the calibration drift assessment requirements in NSPS subpart VVa at 40 CFR 60.485a(b)(2) including: (1) Correcting a regulatory citation to read “§ 60.486a(e)(8)” instead of “§ 60.486a(e)(7)”; (2) removing the extraneous sentence “Calculate the average algebraic difference between the three meter readings and the most recent readings and the most recent calibration value.”; (3) providing clarity in the mathematical step of the assessment by replacing the sentence “Divide this algebraic difference by the initial calibration value and multiply by 100 to express the calibration drift as a percentage.” with “Divide the arithmetic difference of the initial and post-test calibration response by the corresponding calibration gas value for each scale and multiply by 100 to express the calibration drift as a percentage.”; and (4) providing clarity by making other minor textural changes to the provisions related to the procedures for when a calibration drift assessment shows negative or positive drift of more than 10 percent.</P>
                    <P>We also proposed at 40 CFR 63.103(b)(1) (for HON), 40 CFR 63.490(g) and 40 CFR 63.504(a) (for the P&amp;R I NESHAP), and 40 CFR 64.525(a), (e), and (m) (for the P&amp;R II NESHAP) that owners and operators would be required to conduct subsequent performance testing on non-flare control devices no later than 60 calendar months after the previous performance test.</P>
                    <P>We also proposed to: (1) Remove the provisions at 40 CFR 63.110(h) that allow compliance with certain portions of 40 CFR part 264, subpart AA or CC in lieu of portions of NESHAP subpart G; and (2) remove the provisions at 40 CFR 63.110(i) and 40 CFR 60.160(g) that allow compliance with certain portions of 40 CFR part 65 in lieu of portions of NESHAP subparts G and H.</P>
                    <P>Finally, we proposed revisions to clarify text or correct typographical errors, grammatical errors, and cross-reference errors. These editorial corrections and clarifications are discussed in section III.E.5.f of the proposal preamble (see 88 FR 25080, April 25, 2023).</P>

                    <P>In addition, for adsorbers that cannot be regenerated and regenerative adsorbers that are regenerated offsite, we have clarified the proposed rule text in this final action that the monitoring plan provisions in 40 CFR 63.120(d)(2) and (3) do not apply to HON sources subject to the monitoring provisions in 40 CFR 63.120(d)(1)(iii); and the monitoring plan provisions in 40 CFR 63.120(d)(2) and (3) do not apply to P&amp;R I sources subject to the monitoring provisions in 40 CFR 63.120(d)(1)(iii) (via 40 CFR 63.484(t) and 40 CFR 63.485(x)).</P>
                    <P>
                        With regard to overlap provisions, we are: (1) Revising 40 CFR 63.160(b)(1) and (c)(1) in the final rule such that compliance with HON subpart H constitutes compliance with NSPS subpart VVa provided the owner or operator continues to comply with 40 CFR 60.480a(e)(2)(i); and (2) revising 40 CFR 63.160(b)(1) and (c)(1) in the final rule such that compliance with HON subpart H constitutes compliance with NSPS subpart VVb provided the owner or operator continues to comply with 40 CFR 60.480b(e)(2)(i). We have also revised 40 CFR 60.480b(e)(2)(i) in the final rule to require compliance with 40 CFR 60.482-7b (

                    <P>
                        There are approximately 207 facilities subject to the HON, 19 P&amp;R I facilities (and 10 of these P&amp;R I facilities are collocated with HON processes), and 5 P&amp;R II facilities (and 3 of these P&amp;R II facilities are collocated with HON processes). We also estimate that two additional HON facilities will be newly constructed over the next 3 years. The Office of Enforcement and Compliance Assurance's ECHO (Enforcement and Compliance History Online) tool (
                        <E T="03">https://echo.epa.gov</E>
                        ) indicates there are currently 592 SOCMI facilities subject to subpart VV or VVa; and 284 SOCMI facilities subject to at least one of the process vent NSPS subparts III, NNN, and/or RRR. The list of facilities is available in the document titled 
                        <E T="03">Lists of Facilities Subject to the HON, Group I and Group II Polymers and Resins NESHAPs, and NSPS subparts VV, VVa, III, NNN, and RRR</E>
                         (see Docket Item No. EPA-HQ-OAR-2022-0730-0069). We estimate that there will be one new greenfield facility, six new affected facilities constructed at existing plant sites, and 12 modified/reconstructed facilities subject to NSPS subpart IIIa, NNNa, and/or RRRa in the next 5 years. We estimate there will be one new greenfield facility, 34 new affected facilities constructed at existing plant sites, and one modified facility subject to NSPS subpart VVb in the next 5 years (and no affected facilities will trigger NSPS subpart VVa reconstruction requirements).

                    <P>
                        This final action will reduce HAP emissions by at least 1,372 tpy and VOC emissions by 3,820 tpy from HON, P&amp;R I, and P&amp;R II emission sources as well as the NSPS SOCMI air oxidation unit processes, distillation operations, reactor processes, and equipment leaks sources. These emission reductions are broken down by rule as follows. Considering reported emissions inventories for EtO and chloroprene, we estimate that the final amendments to the NESHAP will reduce overall HAP emissions from the SOCMI source category by approximately 1,107 tpy (and 1,919 tpy of VOC), reduce overall HAP emissions from the P&amp;R I source categories by approximately 264 tpy (and 278 tpy of VOC), and reduce overall HAP and VOC emissions from the P&amp;R II source categories by approximately 1 tpy. We note that these emissions reductions do not consider the potential excess emissions reductions from flares that could result from the final monitoring requirements; we estimate flare excess emissions reductions of 4,858 tpy HAP and 19,889 tpy VOC. Based on our analysis of the finalized actions described in sections III.B.2, III.D.2, and III.E of this preamble for the NSPS, we estimate that the final amendments to the NSPS would reduce VOC emissions from the SOCMI source category by approximately 1,622 tpy. The Agency was unable to estimate HAP emission reductions for the final amendments to the NSPS in this rulemaking. Emission reductions and secondary impacts (

                        The EPA conducted economic impact analyses for this rulemaking, in a document titled Regulatory Impact Analysis for the 
                        <E T="03">Final New Source Performance Standards for the Synthetic Organic Chemical Manufacturing Industry and National Emission Standards for Hazardous Air Pollutants for the Synthetic Organic Chemical Manufacturing Industry and Group I &amp; II Polymers and Resins Industry,</E>
                         which is available in the docket for this action. The economic impact analyses contain two parts. The economic impacts of the final rulemaking on small entities are calculated as the percentage of total annualized costs incurred by affected ultimate parent owners to their revenues. This ratio provides a measure of the direct economic impact to ultimate parent owners of HON, P&amp;R I, and P&amp;R II facilities and NSPS subpart VVb, IIIa, NNNa, and RRRa facilities while presuming no impact on consumers. We estimate the average small entity impacted by this final action will incur total annualized costs of 0.5 percent of their revenue, with none exceeding 1.3 percent, not considering product recovery from compliance. With product recovery, the EPA estimates that the average small entity impacted by the rulemaking will incur total annualized costs of 0.49 percent of their revenue, with none exceeding 1.4 percent. We estimate that 25 percent (2 in total) of impacted small entities will incur total annualized costs greater than 1 percent of their revenue, and none will incur total annualized costs greater than 3 percent of their revenue. These estimates are unchanged when including product recovery. This is based on a conservative estimate of costs imposed on ultimate parent companies, where total annualized costs are imposed on a facility are at the upper bound of what is possible under the rule and do not include product recovery as an offset to the annualized costs.
                    </P>
                    <P>In addition, we provide a fuller economic impact analysis using costs of the HON and P&amp;R I and II NESHAP that estimates changes in affected chemical product price and output related to the impact of the compliance costs on producers and consumers of such chemical products for each of these final rules. There are seven chemical products included in the economic impact analysis—butadiene, styrene, acetone, acrylonitrile, ethylene dichloride, ethylene glycol, and EtO. For the HON, chemical product prices are estimated to increase from less than 0.01 percent to 0.61 percent, and output by product is estimated to decrease by less than 0.01 percent to 0.54 percent. For the two P&amp;R NESHAP, chemical product prices are estimated to increase by less than 0.01 percent to 0.05 percent, and output by product is estimated to decrease by less than 0.01 percent to 0.09 percent. More explanation of these economic impacts can be found in the Regulatory Flexibility Act (RFA) section later in this preamble and in the economic impact analysis that is included in the RIA for this final rulemaking.</P>
                    <HD SOURCE="HD2">E. What are the benefits?</HD>
                    <P>The emissions controls required by these rules are expected to reduce emissions of a number of HAP. As stated in section V.B of this preamble, this final action will reduce HAP emissions by at least 1,372 tpy and VOC emissions by 3,820 tpy from HON, P&amp;R I, and P&amp;R II emission sources as well as the NSPS SOCMI air oxidation unit processes, distillation operations, reactor processes, and equipment leaks sources (see Table 7 of this preamble). The health effects associated with the main HAP of concern from SOCMI (found within the HON), P&amp;R I, and P&amp;R II source categories are discussed fully in Chapter 4 of the RIA: EtO (Section 4.1.1), chloroprene (Section 4.1.2), benzene (Section 4.1.3), 1,3-butadiene (Section 4.1.4), vinyl chloride (Section 4.1.5), ethylene dichloride (Section 4.1.6), chlorine (Section 4.1.7), maleic anhydride (Section 4.1.8) and acrolein (Section 4.1.9). This final action is projected to reduce EtO emissions from HON processes by approximately 54 tpy and reduce chloroprene emissions from Neoprene Production processes subject to the P&amp;R I NESHAP by approximately 14 tpy. We also estimate that the final amendments to the NESHAP will reduce other HAP emissions (excluding EtO and chloroprene) from the SOCMI, P&amp;R I, and P&amp;R II source categories by approximately 1,304 tpy. We also estimate that the final amendments to the NESHAP will reduce excess emissions of HAP from flares in the SOCMI and P&amp;R I source categories by an additional 4,858 tpy. The Agency was unable to estimate HAP emission reductions for the final amendments to the NSPS in this rulemaking.</P>

                    <P>Quantifying and monetizing the economic value of reducing the risk of cancer and non-cancer effects is made difficult by the lack of a central estimate of cancer and non-cancer risk and estimates of the value of an avoided case of cancer (fatal and non-fatal) and morbidity effects. Due to methodology and data limitations, we did not attempt to monetize the health benefits of reductions in HAP in this analysis. Instead, we are providing a qualitative discussion in the RIA of the health effects associated with HAP emitted from sources subject to control under the final action. Health effects from reduced exposure to EtO, chloroprene, benzene, 1,3-butadiene, vinyl chloride, ethylene dichloride, chlorine, maleicanhydride, and acrolein are all HAP emissions expected to be reduced by this rule. These pollutants all have been associated with cancer risk is human among other acute health effects.</P>

                        For purposes of analyzing regulatory impacts, the EPA relies upon its June 2016 “Technical Guidance for Assessing Environmental Justice in Regulatory Analysis,” which provides recommendations that encourage analysts to conduct the highest quality analysis feasible, recognizing that data limitations, time, resource constraints, and analytical challenges will vary by media and circumstance. The Technical Guidance states that a regulatory action may involve potential EJ concerns if it could: (1) create new disproportionate impacts on communities with EJ concerns; (2) exacerbate existing disproportionate impacts on communities with EJ concerns; or (3) present opportunities to address existing disproportionate impacts on communities with EJ concerns through this action under development.

(B) Are there potential EJ concerns associated with environmental stressors affected by the regulatory action for population groups of concern for the regulatory option(s) under consideration? (C) For the regulatory option(s) under consideration, are potential EJ concerns created or mitigated compared to the baseline?”

                        For the SOCMI source category, the EPA examined the potential for the 195 HON facilities (for which the EPA had HAP emissions inventories) to pose concerns to communities living in proximity to facilities, both in the baseline and under the control option established in this final action. Specifically, the EPA analyzed how demographics and risk are distributed both pre- and post-control. The methodology and detailed results of the demographic analysis are presented in the document titled 
                        <E T="03">Analysis of Demographic Factors for Populations Living Near Hazardous Organic NESHAP (HON) Operations—Final,</E>

                    <P>
                        To examine the potential for environmental justice concerns, the EPA conducted three different demographic analyses: a baseline proximity analysis, baseline cancer risk-based analysis (
                        <E T="03">i.e.,</E>
                         before implementation of any controls required by this final action), and post-control cancer risk-based analysis (
                        <E T="03">i.e.,</E>
                         after implementation of the controls required by this final action). The baseline proximity demographic analysis is an assessment of individual demographic groups in the total population living within 10 km (~6.2 miles) and 50 km (~31 miles) of the facilities. The baseline risk-based demographic analysis is an assessment of risks to individual demographic groups in the population living within 10 km and 50 km of the facilities prior to the implementation of any controls required by this final action (“baseline”). The post-control risk-based demographic analysis is an assessment of risks to individual demographic groups in the population living within 10 km and 50 km of the facilities after implementation of the controls required by this final action (“post-control”). In this preamble, we focus on the results from the demographic analyses using a 10 km radius because this buffer distance encompasses all the facility maximum individual risk (MIR) locations, captures 97 percent of the population with baseline cancer risks greater than or equal to 50-in-1 million from SOCMI source category emissions, and captures 100 percent of the population with such baseline risks greater than 100-in-1 million. The results of the demographic analyses for populations living within 50 km of facilities are included in the document titled

                        For all three demographic analyses, the affected populations (

                         those living within 10 km of the facilities) are compared to the national population. The total population, population percentages, and population count for each demographic group for the entire U.S. population are shown in the column titled “Nationwide Average for Reference” in Tables 8 through 10 of this preamble. These national data are provided as a frame of reference to compare the results of the baseline proximity analysis, the baseline cancer risk-based analysis, and the post-control cancer risk-based analysis.
                    </P>
                    <P>The results of the baseline proximity analysis indicate that a total of 9.3 million people live within 10 km of the 195 HON facilities. The percent of the population that is Black (25 percent) is more than double the national average (12 percent), and the percent of the population that is Hispanic or Latino (22 percent) is also higher than the national average (19 percent). The percent of people living below the poverty level and the percent of people over the age of 25 without a high school diploma are higher than the national averages. The results of the baseline proximity analysis indicate that the proportion of other demographic groups living within 10 km of HON facilities is similar to or below the national average.</P>
                    <P>The baseline cancer risk-based demographic analysis, which focuses on populations that have higher cancer risks, suggests that Hispanic/Latino individuals and Black individuals living near the facilities are overrepresented with respect to the national average at all cancer risk levels greater than 1-in-1 million. In addition, the percent of households with linguistic isolation (in which all household members over the age of 14 only have limited English proficiency) increases as the Hispanic/Latino population increases. At all risk levels greater than or equal to 1-in-1-million, in cases where the percentage of the population below the poverty level is 1.5 to 2 times the national average, these populations are also above the national averages for Black, American Indian or Alaska Native, Hispanic/Latino, or Other Race/Multiracial populations.</P>
                    <P>
                        The post-control risk-based demographic analysis shows that the controls required by this final action will notably reduce the number of people who are exposed to cancer risks resulting from SOCMI source category emissions at all risk levels. At greater than or equal to a cancer risk of 1-in-1 million, the number of individuals exposed will decrease from 2.8 million to 2.7 million. At greater than or equal to a cancer risk of 50-in-1 million, the number of individuals exposed will decrease from 300,000 to 30,000. And after the control is implemented, there will be no people who are exposed to cancer risks greater than 100-in-1 million resulting from SOCMI source category emissions. Although all demographic populations will see reductions in the number of individuals exposed at each level of risk, there will be individuals who still remain at a cancer risk greater than or equal to 1-in-1 million or greater than or equal to 50-in-1 million risk post-control. The demographic composition of those individuals still exposed to risk greater than or equal to 1-in-1 million will be similar to the demographic composition of the individuals exposed at baseline. At the greater than or equal to 50-in-1 million risk level, the percentages of most demographic populations will be similar to the national average percentages with the exception of the Hispanic/Latino population, which will still be overrepresented with respect to the national average. At the greater than 100-in-1 million risk level, there will be no individuals exposed to cancer risk post-control, so there will be no disparities among demographic groups at this risk level.

                    <P>The column titled “Baseline Proximity Analysis for Pop. Living within 10 km of HON Facilities” in Tables 8 through 10 of this preamble shows the share and count of people for each of the demographic categories for the total population living within 10 km (~6.2 miles) of HON facilities. These are the results of the baseline proximity analysis and are repeated in Tables 8 through 10 of this preamble for easy comparison to the risk-based analyses discussed later.</P>
                    <P>Approximately 9.3 million people live within 10 km of the 195 HON facilities assessed. The results of the proximity demographic analysis indicate that the percent of the population that is Black (25 percent, 2.35M people) is more than double the national average (12 percent). The percent of the population that is Hispanic or Latino (22 percent, 2M people) is higher than the national average (19 percent). The percent of people living below the poverty level (19 percent, 1.75M people) and percent of people over the age of 25 without a high school diploma (16 percent, 1.5M people) are higher than the national averages (13 percent and 12 percent, respectively).

                    <P>The baseline risk-based demographic analysis results are shown in the “baseline” column of Tables 8 through 10 of this preamble. This analysis focused on the populations living within 10 km (~6.2 miles) of the HON facilities with estimated cancer risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (Table 8 of this preamble), greater than or equal to 50-in-1 million (Table 9 of this preamble), and greater than 100-in-1 million (Table 10 of this preamble). The risk analysis indicated that emissions from the source category, prior to the controls required in this final action, expose 2.8 million people living near 111 facilities to a cancer risk greater than or equal to 1-in-1 million, 322,000 people living near 21 facilities to a cancer risk greater than or equal to 50-in-1 million, and 83,000 people living near 8 facilities to a cancer risk greater than 100-in-1 million.</P>
                    <P>In the baseline, there are 2.8 million people living around 111 HON facilities with a cancer risk greater than or equal to 1-in-1 million resulting from SOCMI source category emissions. The 111 HON facilities are located across 17 states, but two-thirds of them are located in Texas and Louisiana (50 in Texas and 33 in Louisiana). Ninety percent of the people with risks greater than or equal to 1-in-1 million are living around 29 of the 111 HON facilities. All but three of these 29 facilities are located in Texas and Louisiana. The percent of the baseline population with estimated cancer risks greater than or equal to 1-in-1 million who are Black (25 percent, 692,000 people) is well above the average percentage of the national population that is Black (12 percent). The Black population living within 10 km of two facilities in Louisiana account for about a quarter of the total Black population with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions.</P>
                    <P>The percent of the population with cancer risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions prior to the controls required in this final action that is Hispanic or Latino (34 percent, 958,000 people) is significantly higher than that in the baseline proximity analysis (22 percent, 2 million people) and well above the national average (19 percent). The population around an Illinois facility is over 75 percent Hispanic or Latino, and accounts for a quarter of the Hispanic/Latino population with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions. Another group of 5 facilities in the Houston/Channelview Texas area have local populations that are between 60 and 90 percent Hispanic/Latino, and those communities account for 31 percent of the Hispanic/Latino population with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions. The percent of the population that is linguistically isolated in the baseline with cancer risks greater than or equal to 1-in-1 million (8 percent, 228,000 people) is higher than the percentage in the baseline proximity analysis (5 percent, 510,000 people). The areas with the highest Hispanic/Latino population are some of those with the highest percent linguistic isolation.</P>
                    <P>Overall, the percent of the baseline population that is American Indian or Alaska Native with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (0.2 percent) is well below the national average (0.7 percent). The population with baseline risks resulting from SOCMI source category emissions greater than or equal to 1-in-1 million have a percent American Indian or Alaska Native population that is more than 2 times the national average. These facilities are located in Texas (3), Louisiana, Montana, Illinois, and Kansas.</P>
                    <P>The percent of the population below the poverty level with cancer risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (18 percent, 513,000 people) is above the national average (13 percent). The percent of the population living below the poverty level within 10 km of 19 facilities is twice the national average. The percent of the population over 25 years old without a high school diploma with cancer risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (20 percent, 561,000 people) is greater than the national average (13 percent) as well as greater than the overall percent of the population living near HON facilities who are over 25 years old without a high school diploma (16 percent, 1.5 million people).</P>
                    <P>In the baseline, there are 322,000 people living around 21 HON facilities with a cancer risk greater than or equal to 50-in-1 million resulting from SOCMI source category emissions. The 21 HON facilities are located across 6 states, but two-thirds of them are located in Texas and Louisiana. Ninety-six percent of the people with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions live around 5 HON facilities, which are located in Texas or Louisiana. The percent of the population that is Black with baseline cancer risk greater than or equal to 50-in-1 million resulting from SOCMI source category emissions (18 percent, 59,000 people) is above the national average (12 percent) but is significantly lower than the percent of the population that is Black with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (25 percent, 692,000 people). The percentage of Black individuals is greater than the national average near over half of the facilities (12 facilities) where cancer risk is greater than 50-in-1 million resulting from HON source category emissions. The populations near two facilities in Texas account for about 70 percent of the number of Black individuals with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions.</P>

                        similar to the percentage of the population that is Hispanic/Latino in the total population living within 10 km of the facilities (22 percent). The percent of population that is Hispanic/Latino with cancer risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions is above the national average at over half of the facilities (13 facilities). The population near three facilities in Texas accounts for about 80 percent of the number of Latino/Hispanic people with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions.
                    </P>
                    <P>Overall, the percent of the population that is American Indian or Alaska Native with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions (0.2 percent) is below the national average (0.7 percent). Populations near four facilities with baseline risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions have a percent American Indian or Alaska Native population that is more than 2 times the national average. These facilities are located in Texas (3) and Louisiana.</P>
                    <P>The percentage of the population with cancer risks resulting from SOCMI source category emissions greater than or equal to 50-in-1 million that are below the poverty level (15 percent), over 25 years old without a high school diploma (15 percent), or are linguistically isolated (5 percent) are similar to or slightly above the respective national averages. Of the population with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions, the percentage of the population below the poverty level is twice the national average near five facilities. For all 5 of these facilities, the percentage of the population is also 2 times the national average percentage for at least one race/ethnic demographic category.</P>
                    <P>In the baseline, there are 83,000 people living around 8 HON facilities with a cancer risk resulting from SOCMI source category emissions greater than 100-in-1 million. These 8 HON facilities are located in Texas and Louisiana. The percent of the population that is Black with baseline cancer risk greater than 100-in-1 million resulting from SOCMI source category emissions (14 percent) is just above the national average (12 percent). The percentage of the Black population with cancer risks greater than 100-in-1 million resulting from SOCMI source category emissions is between 2 to 4 times greater than the national average at three facilities in Texas and one in Louisiana.</P>
                    <P>The percentage of the population that is Hispanic/Latino with risks greater than 100-in-1 million resulting from SOCMI source category emissions (26 percent, 22,000 people) is above the national average (19 percent) and is similar to the share of the population that is Hispanic/Latino with cancer risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions (25 percent, 81,000 people). The share of the Hispanic and Latino population with cancer risks greater than 100-in-1 million resulting from SOCMI source category emissions is between 2 to 3 times greater than the national average at five facilities in Texas and one in Louisiana.</P>
                    <P>Overall, the percent of the baseline population that is American Indian or Alaska Native with risks greater than or equal to 100-in-1 million resulting from SOCMI source category emissions (0.2 percent) is well below the National Average (0.7 percent).</P>
                    <P>The percentage of the population with cancer risks greater than 100-in-1 million resulting from SOCMI source category emissions that are below the poverty level (14 percent), over 25 without a high school diploma (14 percent), or linguistically isolated (5 percent) are similar or slightly above the respective national averages. The percent of the population below the poverty level is 1.5 times the national average at five facilities. The population living around three of these facilities is also 1.5 times the national average for at least one race/ethnic demographic category.</P>
                    <P>In summary, the baseline risk-based demographic analysis, which focuses on populations that are expected to have higher cancer risks resulting from SOCMI source category emissions, suggests that Hispanic or Latino individuals are disproportionally overrepresented at all cancer risk levels. Specifically, the percentage of the population that is Hispanic/Latino is almost twice the national average at a cancer risk equal to or greater than 1-in-1 million and almost 1.5 times the national average at the 50-in-1-million and 100-in-1-million risk levels. Similarly, the Black population is disproportionately overrepresented at all cancer risk levels in the baseline risk analysis. The percentage of Black individuals with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions is twice the national average and 1.5 times the national average at the 50-in-1-million risk level. In most cases, when the percentage of the population below the poverty level is greater than 1.5 times the national average, the percentage of the population that is Black, American Indian or Alaska Native, Hispanic/Latino, or Other/Multiracial is above the national average.</P>

                    <P>This analysis focused on the populations living within 10 km (~6.2 miles) of the facilities with estimated cancer risks greater than or equal to 1-in-1 million (Table 8 of this preamble), greater than or equal to 50-in-1 million (Table 9 of this preamble), and greater than 100-in-1 million (Table 10 of this preamble) resulting from SOCMI source category emissions after implementation of the control options for HON sources investigated under the residual risk analysis as described in section III.B.2.a of this preamble (“post-control”). The results of the post-control risk-based demographics analysis are in the columns titled “Post-Control” of Tables 8 through 10 of this preamble. In this analysis, we evaluated how all of the controls required by this final action and emission reductions for HON processes described in this action affect the distribution of risks. This makes it possible to characterize the post-control risks and to evaluate whether the final action creates or mitigates potential environmental justice concerns as compared to the baseline.</P>
                    <P>The risk analysis indicated that the number of people within 10 km of a facility exposed to risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (Table 8 of this preamble) is reduced from 2.8 million people in the baseline to approximately 2.7 million people after implementation of the HON controls required by this final action. The populations with a cancer risk greater than or equal to 1-in-1 million resulting from SOCMI source category emissions are located around 111 facilities for both the baseline and post-control.</P>
                    <P>
                        The post-control population living within 10 km of a facility with estimated cancer risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (Table 8 of this preamble) has similar demographic percentages to the baseline population with risks greater than or equal to 1-in-1 million. However, the number of individuals with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions is reduced in each demographic. Specifically, the percentage of the population with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions that is 
                        <PRTPAGE P="43038"/>
                        Black remains high at 25 percent in the post-control scenario, but the number of Black individuals with risks at or above 1-in-1 million is reduced by over 25,000 people from 692,000 in the baseline to 664,000 in the post-control scenario.
                    </P>
                    <P>Similarly, the percentage of the population with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions that is Hispanic/Latino is almost twice the national average in the post-control scenario (35 percent versus 19 percent), but the number of Hispanic/Latino individuals with risks at or above 1-in-1 million is reduced by about 24,000 people from 958,000 in the baseline to 934,000 in the post-control scenario.</P>
                    <P>The percent of the population that is American Indian or Alaska Native with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions (0.2 percent) is below the national average (0.7 percent) in the post-control analysis. Nevertheless, there are seven facilities post-control with risks greater than or equal to 1-in-1 million with a percent American Indian or Alaska Native population that is more than 2 times the national average. However, the number of American Indians or Alaska Natives with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions is reduced from 6,000 in the baseline to 5,000 in the post-control scenario.</P>
                    <P>The percent of the population below the poverty level is the same in the post-control scenario as in the baseline (18 percent), but the number of individuals with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions that are below the poverty level is reduced by 20,000, from 513,000 to 493,000. The percent of individuals over 25 years old without a high school diploma is the same in the post-control scenario as in the baseline (20 percent), but the number of individuals with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions is reduced by almost 23,000, from 561,000 to 538,000. The percentage of the population that is in linguistic isolation with risks greater than or equal to 1-in-1 million resulting from SOCMI source category emissions is the same in the post-control scenario (8 percent), but the number of individuals is reduced by almost 8,000 compared to the baseline, from 228,000 to 220,000.</P>
                    <P>The risk analysis indicated that the number of people living within 10 km of a facility and exposed to risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions (Table 9 of this preamble) is reduced significantly from 322,000 people in the baseline to 29,000 after implementation of the controls required by this final action. This represents more than a 90 percent reduction in the number of individuals with risk greater than or equal to 50-in-1 million when compared to the baseline. The populations living within 10 km of a facility and with a cancer risk greater than or equal to 50-in-1 million resulting from SOCMI source category emissions are located around 13 facilities in the post-control scenario, 8 fewer facilities than in the baseline. These 13 facilities are located in Alabama, Arkansas, Illinois, Kentucky, Louisiana (5 facilities), and Texas (4 facilities). The communities within 10 km of five of those facilities (in Texas (3 facilities), Alabama, and Illinois) comprise 95 percent of the population with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions.</P>
                    <P>The number of individuals with risks greater than or equal to 50-in-1 million is reduced significantly for each demographic category in the post-control scenario. Specifically, the percentage of the population with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions that is Black decreased in the post-control scenario and is equal to the national average (12 percent). The number of Black individuals with risks at or above 50-in-1 million is reduced from 59,000 in the baseline to 4,000 post-control. The percentage of the population with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions that is Hispanic/Latino increased from 25 percent in the baseline to 29 percent post-control, but the number of Hispanic/Latino individuals with risks at or above 50-in-1 million is reduced from 81,000 in the baseline to 9,000 post-control.</P>
                    <P>Overall, the percent of the population that is American Indian or Alaska Native with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions (0.3 percent) is well below the national average (0.7 percent) in the post-control scenario. In addition, the number of American Indians or Alaska Natives with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions is reduced from 600 in the baseline to less than 100 post-control.</P>
                    <P>The percent of the population with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions whose income is below the poverty level (11 percent) is reduced from the baseline (15 percent) post-control. In addition, the number of individuals with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions who are below the poverty level is reduced from 47,000 to 3,000. The number of individuals with risks greater than or equal to 50-in-1 million resulting from SOCMI source category emissions that are over 25 years old without a high school diploma or are linguistically isolated are also greatly reduced post-control.</P>
                    <P>The risk analysis indicated that the number of people living within 10 km of a facility with risks greater than 100-in-1 million resulting from SOCMI source category emissions (Table 10 of this preamble) is reduced from 83,000 individuals in the baseline to zero individuals after application of the SOCMI controls required by this final action. Therefore, for the post-control risk-based demographic results, there are no greater than 100-in-1 million demographic results to discuss.</P>
                    <P>In summary, as shown in the post-control risk-based demographic analysis, the controls required by this final action significantly reduce the number of people expected to have cancer risks greater than or equal to 1-in-1 million, greater than or equal to 50-in-1 million, and greater than 100-in-1 million resulting from SOCMI source category emissions. Although the number of individuals with risks greater than or equal to 1-in-1 million is reduced in the post-control scenario (reduced from 2.8 million people to 2.7 million people), populations of Black individuals, Hispanic/Latino individuals, those living below the poverty level, and those over 25 without a high school diploma remain disproportionately represented. Similarly, the number of individuals with risks greater than or equal to 50-in-1 million is reduced significantly in the post-control scenario (reduced from 322,000 to 29,000), but the population of Black individuals remains disproportionately represented. Post-control, there are no individuals with risks greater than 100-in-1 million resulting from SOCMI source category emissions (reduced from 83,000 people to 0 people).</P>

                    <P>As described in Section III.A.5 of this preamble, we assessed the facility-wide (or “whole-facility”) risks for 195 HON facilities in order to compare the SOCMI source category risk to the whole-facility risks, accounting for HAP emissions from the entire major source and not just those resulting from SOCMI source category emissions at the major source as discussed in the previous section. The whole-facility risk analysis includes all sources of HAP emissions at each facility as reported in the NEI (described in section III.C of the preamble to the proposed rule). Since HON facilities tend to include HAP emissions sources from many source categories, the EPA conducted a whole-facility demographic analysis focused on post-control risks. This whole-facility demographic analysis characterizes the remaining risks communities face after implementation of the controls required in this final action for both the SOCMI source category and the Neoprene Production source category.</P>
                    <P>
                        The whole-facility demographic analysis is an assessment of individual demographic groups in the total population living within 10 km (~6.2 miles) and 50 km (~31 miles) of the facilities. In this preamble, we focus on the 10 km radius for the demographic analysis because, based on SOCMI category emissions, this distance includes all the facility MIR locations, includes 97 percent of the population with cancer risks greater than or equal to 50-in-1 million, and includes 100 percent of the population with risks greater than 100-in-1 million. The results of the whole-facility demographic analysis for populations living within 50 km are included in the document titled 
                        <E T="03">Analysis of Demographic Factors for Populations Living Near Hazardous Organic NESHAP (HON) Operations: Whole Facility Analysis—Final,</E>

                    <P>The whole-facility demographic analysis post-control results are shown in Table 11 of this preamble. This analysis focused on the populations living within 10 km of the HON facilities with estimated whole-facility post-control cancer risks greater than or equal to 1-in-1 million, greater than or equal to 50-in-1 million, and greater than 100-in-1 million. The risk analysis indicated that all emissions from the HON facilities, after the reductions imposed by the final rule, expose a total of about 3 million people living around 140 facilities to a cancer risk greater than or equal to 1-in-1 million, 79,000 people living around 24 facilities to a cancer risk greater than or equal to 50-in-1 million, and 2,900 people living around 4 facilities to a cancer risk greater than 100-in-1 million.</P>
                    <P>
                        When the HON whole-facility populations are compared to the SOCMI source category populations in the post-control scenarios, we see 400,000 additional people with risks greater than or equal to 1-in-1 million, 50,000 additional people with risks greater than or equal to 50-in-1 million, and 2,900 additional people with risks greater than 100-in-1 million. With the exception of a smaller percentage of affected Hispanic/Latino individuals (35 percent for category versus 33 percent whole-facility), the demographic distribution of the whole-facility population with risks greater than or equal to 1-in-million is similar to the source category population with risks greater than or equal to 1-in-1 million in the post-control scenario. The population with risks greater than or equal to 50-in-1 million in the whole-facility analysis has a lower percent of Hispanic/Latino individuals than the category population with risks greater than or equal to 50-in-1 million (25 percent versus 29 percent). The percentage of the population with risks greater than or equal to 50-in-1 million that is below the poverty level or over 25 years old without a high school diploma is higher for the whole-facility post-control population than for the category post-control population (14 percent versus 11 percent). The SOCMI source category emissions analysis indicated that there are no people with post-control risks greater than 100-in-1 million. Based on results from the whole-facility emissions analysis, there are 2,900 people with post-control risks greater than 100-in-million. The increased cancer risk for most of these 2,900 people is driven by EtO emissions from non-HON processes and whole-facility emissions from the neoprene production facility (a combination of the remaining SOCMI category risk and Neoprene Production category risk at this facility). The percent of the population in the whole-facility analysis with post-control risks greater than 100-in-1 million that is Black (25 percent, 700 individuals) is well above the national average (12 percent). In addition, the percent of the population in the whole-facility analysis with a post control risk greater than 100-in-1 million that is below the poverty level (22 percent, 600 individuals), and the percent of the population that is over 25 years old without a high school diploma (27 percent, 800 individuals) are above the national average (13

                        percent and 12 percent, respectively). We note that as further discussed in section IV.B of this preamble, the EPA is finalizing a fenceline action level of 0.2 µg/m
                        <SU>3</SU>
                         for EtO for the whole-facility. As such, we believe that once fenceline monitoring is fully implemented, that whole-facility post-control risks will be lower and the number of people presented in Table 11 of this preamble at each risk threshold will be lower.

                        For the Neoprene Production source category subject to the P&amp;R I NESHAP, the EPA examined the potential for the one neoprene production facility to pose environmental justice concerns to communities both in the baseline and under the control option required in this final action. Specifically, the EPA analyzed how demographics and risk are distributed both pre- and post-controls. The methodology and detailed results of the demographic analysis are presented in a technical report, 
                        <E T="03">Analysis of Demographic Factors for Populations Living Near Neoprene Production Operations—Final,</E>
                         which is available in the docket for this rulemaking.
                    </P>
                    <P>To examine the potential for environmental justice concerns in the pre-control baseline, the EPA conducted three different demographic analyses: a baseline proximity analysis, baseline cancer risk-based analysis, and post-control cancer risk-based analysis. These analyses (total baseline, baseline risk, and post-control risks) assessed the demographic groups in the populations living within 5 km (~3.1 miles) and 50 km (~31 miles) of the facility. For the Neoprene Production source category, we focus on the 5 km radius for the demographic analysis because it encompasses the facility MIR location and captures 100 percent of the population with cancer risks resulting from Neoprene Production source category emissions greater than or equal to 50-in-1 million and greater than 100-in-1 million. The results of the proximity analysis for populations living within 50 km are included in the technical report included in the docket for this final action. Nationwide average demographics data are provided as a frame of reference.</P>
                    <P>The results of the proximity demographic analysis indicate that a total of about 29,000 people live within 5 km of the Neoprene facility. The percent of the population that is Black is more than four times the national average. The percent of people living below the poverty level is almost double the national average.</P>
                    <P>The baseline risk-based demographic analysis indicates that Black individuals are disproportionally overrepresented at all cancer risk levels resulting from Neoprene Production source category emissions (percent of Black individuals range from 5 to 7 times the national average percent). The percent of the population that is below the poverty level is twice the national average within 5 km of the Neoprene facility.</P>
                    <P>The post-control risk-based demographic analysis indicates that the controls required for Neoprene Production source category in this final action do not reduce the number of people with cancer risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million at the 5 km distance. However, the controls do significantly reduce the number of people with risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million within 50 km. The populations with risks resulting from Neoprene Production source category emissions greater than or equal to 50-in-1 million and greater than 100-in-1 million are reduced at all distances by more than 88 percent by the controls for the Neoprene Production source category under consideration. In the post-control scenario, there are no people with risks resulting from Neoprene Production source category emissions greater than 100-in-1 million.</P>
                    <HD SOURCE="HD3">a. Baseline Proximity Analysis</HD>
                    <P>The column titled “Total Population Living within 5 km of Neoprene Facility” in Tables 12 through 14 of this preamble shows the demographics for the total population living within 5 km (~3.1 miles) of the neoprene facility. A total of about 29,000 people lives within 5 km of the one neoprene facility. The results of the proximity demographic analysis indicate that the percentage of the population that is Black (56 percent, 16,000 people) is more than four times the national average (12 percent). The percentage of people living below the poverty level (23 percent, 6,500 people) and those over the age of 25 without a high school diploma (16 percent, 4,500 people) are higher than the national averages (13 percent and 12 percent, respectively). The baseline proximity analysis indicates that the proportion of other demographic groups living within 5 km of the neoprene facility is similar to or below the national average.</P>
                    <HD SOURCE="HD3">b. Baseline Risk-Based Demographics</HD>
                    <P>The baseline risk-based demographic analysis results are shown in the “baseline” column of Tables 12 through 14 of this preamble. This analysis focused on the populations living within 5 km (~3.1 miles) of the neoprene facility with estimated cancer risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million (Table 12 of this preamble), greater than or equal to 50-in-1 million (Table 13 of this preamble), and greater than 100-in-1 million (Table 14 of this preamble) in the absence of the reductions we are finalizing in this action.</P>
                    <P>In the baseline, emissions from the Neoprene Production source category expose all individuals within 5 km of the facility (29,000 people) to a cancer risk greater than or equal to 1-in-1 million. Since the entire population within 5 km are exposed to risks greater than or equal to 1-in-1 million, the demographics of the baseline at-risk population are the same as the total baseline population. Specifically, a high percentage of the population is Black (56 percent versus 12 percent nationally), below the poverty line (23 percent versus 13 percent nationally), and over the age of 25 without a high school diploma (16 percent versus 12 percent nationally). The percentages of other demographic groups within the population with risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million living within 5 km of the neoprene facility are similar to or below the national average. Within 50 km (~31 miles) of the facility, about 70 percent of the population (687,000 people of the 1 million total within 50 km) is exposed to a cancer risk resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million. Additional details on the 50 km results can be found in the demographics report located in the docket.</P>
                    <P>The risk-based demographics analysis indicates that emissions from the source category, prior to the reductions we are finalizing in this action, expose about 13,000 individuals within 5 km of the facility to a cancer risk greater than or equal to 50-in-1 million (about half of the total population within 5 km). As seen at the lower risk level of greater than or equal to 1-in-1 million, the population with risks greater than or equal to 50-in-1 million has a very high percentage of Black individuals; that percent is almost 6 times the national average (68 percent versus 12 percent nationally). The percentage of the population that is below the poverty line is more than double the national average (27 percent versus 13 percent nationally), and the percentage of the population that is over the age of 25 without a high school diploma is 1.5 times the national average (18 percent versus 12 percent nationally). The percentages of other demographic groups within the population with risks resulting from Neoprene Production source category emissions greater than or equal to 50-in-1 million living within 5 km of the Neoprene facility are similar to or below the national average.</P>
                    <P>
                        In the baseline, there are 2,000 people living within 5 km of the Neoprene 
                        <PRTPAGE P="43048"/>
                        facility with a cancer risk greater than 100-in-1 million resulting from Neoprene Production source category emissions. The percent of the population that is Black with baseline cancer risk greater than 100-in-1 million (85 percent, 1,750 people) is over 7 times the national average (12 percent). The percentage of the population with cancer risks greater than 100-in-1 million that is below the poverty level (31 percent, 600 people) is about 2.5 times the national average (13 percent). The percent of the population that is over 25 without a high school diploma (14 percent, 300 people) is just above the national average (12 percent).
                    </P>
                    <P>In summary, the baseline risk-based demographic analysis, which focuses on those specific locations that are expected to have higher cancer risks in the baseline, indicates that Black individuals are disproportionally overrepresented at all cancer risk levels. Specifically, at all risk levels, the percent of the population that is Black is 5 to 7 times the national average and the percent of the population that is below the poverty level is twice the national average within 5 km of the neoprene production facility.</P>
                    <HD SOURCE="HD3">c. Post-Control Risk-Based Demographics</HD>
                    <P>This analysis focused on the populations living within 5 km (~3.1 miles) of the facility with estimated cancer risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million (Table 12 of this preamble), greater than or equal to 50-in-1 million (Table 13 of this preamble), and greater than 100-in-1 million (Table 14 of this preamble) after implementation of the Neoprene Production source category control options as described in section III.B.2.b of this preamble. The results of the post-control risk-based demographics analysis are in the columns titled “Post-Control” of Tables 12 through 14 of this preamble. In this analysis, we evaluated how all of the controls required by this final action and emission reductions for the Neoprene Production source category described in this action affect the distribution of risks. This makes it possible to characterize the post-control risks and to evaluate whether the final action creates or mitigates potential environmental justice concerns as compared to the baseline.</P>
                    <P>The risk analysis indicated that the number of people exposed to risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million within 5 km of the facility (Table 12 of this preamble) is unchanged from the baseline (29,000 people). Therefore, the population living within 5 km of the facility with estimated cancer risks greater than or equal to 1-in-1 million in the post-control scenario (Table 12 of this preamble) has the same demographic percentages as the total population in the proximity analysis and the population with risks greater than or equal to 1-in-1 million in the baseline risk analysis. Specifically, the percentage of the population with risks resulting from Neoprene Production source category emissions in the post-control analysis that is greater than or equal to 1-in-1 million and is Black (56 percent) is almost 5 times the national average (12 percent), and the percent below the poverty level (23 percent) is almost 2 times the national average (13 percent). However, after control, the number of people exposed to risk greater than or equal to 1-in-1 million within 50 km (~31 miles) of the facility is significantly reduced from 687,000 to 58,000.</P>
                    <P>The risk analysis indicated that the number of people living within 5 km of the facility and exposed to risks greater than or equal to 50-in-1 million resulting from Neoprene Production source category emissions (Table 13 of this preamble) is reduced significantly from about 13,000 people in the baseline to 1,450 people after implementation of the controls required by this final action. This represents more than an 88 percent reduction in the size of the populations at risk when compared to the baseline population. The post-control population living within 5 km of the facility with estimated cancer risks greater than or equal to 50-in-1 million for post-control (Table 13 of this preamble) is almost entirely Black (92 percent). The number of Black individuals with risks greater than or equal to 50-in-1 million is reduced from about 9,000 in the baseline to 1,350 people post-control. Similarly, the post-control population with risks greater than or equal to 50-in-1 million has a high percent of people below poverty (33 percent). The number of people with risks greater than or equal 50-in-1 million that are below the poverty level is reduced from 3,400 in the baseline to 500 people post-control.</P>
                    <P>The risk analysis indicated that the number of people living within 5 km of the facility and exposed to risks greater than 100-in-1 million resulting from Neoprene Production source category emissions (Table 14 of this preamble) is reduced from over 2,000 people in the baseline to zero people after application of the controls required by this final action. Therefore, for the post-control risk-based demographics, there are no people with risks above 100-in-1 million resulting from Neoprene Production source category emissions.</P>
                    <P>In summary, as shown in the post-control risk-based demographic analysis, the controls required by this final action do not reduce the number of people expected to have cancer risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million at the 5 km distance. The controls do significantly reduce the number of people with risks resulting from Neoprene Production source category emissions greater than or equal to 1-in-1 million within 50 km. In the post-control population with risks greater than or equal to 1-in-1 million, Black individuals and those living below the poverty level remain disproportionately represented. For the populations with risks greater than or equal to 50-in-1 million and greater than 100-in-1 million, the controls under consideration reduce the at-risk populations by more than 88 percent at all distances. In the post-control population with risks greater than or equal to 50-in-1 million, Black individuals and those living below the poverty level remain disproportionately represented. Post-control, there are no people with risks resulting from Neoprene Production source category emissions greater than 100-in-1 million.</P>

                    <P>
                        We also evaluated the whole-facility post-control risks at the neoprene production facility. The whole-facility post-control risks include all known sources of HAP emissions at the neoprene production facility, not just those from neoprene production processes. This whole-facility demographic analysis provides a more complete picture of the remaining risks at the facility after implementation of the controls required by this final action and the populations exposed to emissions resulting from them. The post-control whole-facility emissions at the neoprene production facility are a combination of the remaining SOCMI source category risk and Neoprene Production source category risk at this facility. Based on whole-facility emissions, there are a total of about 29,000 people living within 5 km (~3.1 miles) with risks greater than or equal to 1-in-1 million after controls, which is unchanged from the baseline. There are 87,000 people within 50 km of the neoprene facility with post-control whole-facility risks greater than or equal to 1-in-1 million, which is a 90 percent reduction of the 891,000 people in the 
                        <PRTPAGE P="43049"/>
                        baseline. The population within 5 km with post-control whole-facility risks of greater than or equal to 1-in-1 million is 56 percent Black, and 23 percent are below the poverty level. Based on whole-facility emissions there are a total of about 3,000 people remaining after controls living within 5 km and 50 km of the neoprene facility with risks greater than or equal to 50-in-1 million (a reduction of 82 percent from the baseline of 16,000 people). This population is 81 percent Black and 30 percent below the poverty level. Based on whole-facility emissions, about 300 people with risks greater than 100-in-1 million remain after controls are implemented living within 5 km and 50 km of the neoprene production facility (a reduction of 86 percent from the baseline of 2,300 people). This population is 99 percent Black, and 33 percent are below the poverty level. We note that as further discussed in section IV.B of this preamble, the EPA is finalizing a secondary fenceline action level of 0.3 µg/m
                        <SU>3</SU>
                         for chloroprene for the whole-facility. As such, we believe once fenceline monitoring is fully implemented, that whole-facility post-control risks will be reduced to at or below 100-in-1 million and that 0 people (rather than the approximate 300 people as shown in this analysis) will have lifetime cancer risks greater than 100-in-1 million post-control.

                        As stated above, for the P&amp;R I and P&amp;R II NESHAP, other than the Neoprene Production source category within the P&amp;R I NESHAP, we have not conducted a risk analysis for this final action. Therefore, to examine the potential for any environmental justice concerns that might be associated with P&amp;R I (excluding neoprene) or P&amp;R II facilities, we performed a proximity demographic analysis, which is an assessment of individual demographic groups of the populations living within 5 km (~3.1 miles) and 50 km (~31 miles) of the facilities. The EPA then compared the data from this analysis to the national average for each of the demographic groups. In this preamble, we focus on the proximity results for the populations living within 5 km (~3.1 miles) of the facilities. The results of the proximity analysis for populations living within 50 km are included in the document titled

                        The locations of the new, modified, and reconstructed sources that will become subject to NSPS subpart VVb are not known. Therefore, to provide information on the potential for any environmental justice issues that might be associated with the final NSPS subpart VVb, we performed a proximity demographic analysis for 575 existing facilities that are currently subject to NSPS subparts VV or VVa. These

                        represent facilities that might modify or reconstruct in the future and become subject to the NSPS subpart VVb requirements. This proximity demographic analysis characterized the individual demographic groups of the populations living within 5 km and within 50 km (~31 miles) of the existing facilities. The EPA then compared the data from this analysis to the national average for each of the demographic groups.
                    </P>
                    <P>The proximity demographic analysis shows that, within 5 km of the facilities, the percent of the population that is Black is double the national average (24 percent versus 12 percent) (Table 16 of this preamble). The percent of people within 5 km living below the poverty level is significantly higher than the national average (20 percent versus 13 percent). The percent of people living within 5 km that are over 25 without a high school diploma is also higher than the national average (17 percent versus 12 percent). The proximity demographics analysis shows that within 50 km of the facilities, the percent of the population that is Black is above the national average (15 percent versus 12 percent). At 50 km, the remaining percentages for the demographics are similar to or below the national average.</P>

                    <P>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 EPA expects this final action would not reduce crude oil supply, fuel production, coal production, natural gas production, or electricity production. We estimate that this final action would have minimal impact on the amount of imports or exports of crude oils, condensates, or other organic liquids used in the energy supply industries. Given the minimal impacts on energy supply, distribution, and use as a whole nationally, no significant adverse energy effects are expected to occur. For more information on these estimates of energy effects, please refer to the economic impact analysis contained in the RIA for this final rulemaking.</P>

                    <P>This action involves technical standards. As discussed in the proposal preamble (88 FR 25080, April 25, 2023), the EPA conducted searches for the HON and the P&amp;R I and P&amp;R II NESHAP through the Enhanced National Standards Systems Network Database managed by the American National Standards Institute (ANSI). We also conducted a review of voluntary consensus standards (VCS) organizations and accessed and searched their databases. We conducted searches for EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3B, 4, 18, 21, 22, 25A, 25D, 26, 26A, 27 of 40 CFR part 60, Appendix A, 301, 305, 316 and 320 of 40 CFR part 63, Appendix A, 624, 625, 1624, and 1625 of 40 CFR part 136 Appendix A, 624.1 of 40 CFR part 163, Appendix A. During the EPA's 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 particular VCS. No applicable voluntary consensus standards were identified for EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 21, 22, 25D, 27, 305, 316, 624, 624.1, 625, 1624 and 1625.</P>

                    <P>The EPA incorporates by reference VCS ASTM D6420-18, “Standard Test Method for Determination of Gaseous Organic Compounds by Direct Interface Gas Chromatography-Mass Spectrometry” as an acceptable alternative to EPA Method 18 (referenced in NSPS subparts VV, VVa, VVb, III, IIIa, NNN, NNNa, RRR, and RRRa, and NESHAP subparts F, G, H, I, U, and W) with the following caveats. This ASTM procedure uses a direct interface gas chromatograph/mass spectrometer to identify and quantify VOC and has been approved by the EPA as an alternative to EPA Method 18 only when the target compounds are all known and the target compounds are all listed in ASTM D6420 as measurable. ASTM D6420-18 should not be used for methane and ethane because the atomic mass is less than 35; and ASTM D6420 should never be specified as a total VOC method. The ASTM D6420-18 test method employs a direct interface gas chromatograph/mass spectrometer to measure 36 VOC. The test method provides onsite analysis of extracted, unconditioned, and unsaturated (at the instrument) gas samples from stationary sources.</P>

                        The EPA incorporates by reference VCS ASTM D6348-12 (Reapproved 2020), “Standard Test Method for Determination of Gaseous Compounds by Extractive Direct Interface Fourier Transform Infrared (FTIR) Spectroscopy” as an acceptable alternative to EPA Method 320 (referenced in NESHAP subparts F and U) with caveats requiring inclusion of selected annexes to the standard as mandatory. This ASTM procedure uses an extractive sampling system that routes stationary source effluent to an FTIR spectrometer for the identification and quantification of gaseous compounds. We note that we proposed VCS ASTM D6348-12e1 as an alternative to EPA Method 320; however, since proposal, a newer version of the method (VCS ASTM D6348-12 (Reapproved 2020)) is now available and we have determined it to be equivalent to EPA Method 320 with caveats. The VCS ASTM D6348-12

                        (Reapproved 2020) method is an extractive FTIR Spectroscopy-based field test method and is used to quantify gas phase concentrations of multiple target compounds in emission streams from stationary sources. When using ASTM D6348-12 (Reapproved 2020), the following conditions must be met: (1) Annexes Al through A8 to ASTM D6348-12 (Reapproved 2020) are mandatory; and (2) in ASTM D6348-12 (Reapproved 2020) Annex A5 (Analyte Spiking Technique), the percent (%) R must be determined for each target analyte (Equation A5.5). In order for the test data to be acceptable for a compound, %R must be 70% ≥ R ≤ 130%. If the %R value does not meet this criterion for a target compound, the test data is not acceptable for that compound and the test must be repeated for that analyte (

                         the sampling and/or analytical procedure should be adjusted before a retest). The %R value for each compound must be reported in the test report, and all field measurements must be corrected with the calculated %R value for that compound by using the following equation:

                        While the EPA identified 13 other VCS as being potentially applicable, the Agency decided not to use them because these methods are impractical as alternatives because of the lack of equivalency, documentation, validation date, and other important technical and policy considerations. The search and review results have been documented and are in the memorandum,

Method SW-846-5030B can be used as a purge-and-trap procedure for the analysis of volatile organic compounds in aqueous samples and water miscible liquid samples. Method SW-846-5031 can be used for separation of nonpurgeable, water-soluble, and volatile organic compounds in aqueous samples or leachates from solid matrices using azeotropic distillation. Method SW-846-8260D can be used to determine VOCs in a variety of solid waste matrices and is applicable to nearly all types of samples, regardless of water content. The Modified El Paso Method utilizes dynamic or flow-through system for air stripping a sample of water and analyzing the resultant off-gases for VOCs using a common flame ionization detector (FID) analyzer. Each of these methods is used to identify organic HAP in water; however, SW-846-5031, SW-846-8260D, and SW-846-5030B use water sampling techniques and the Modified El Paso Method uses an air stripping sampling technique.

The ASTM D240-19 method addresses the determination of net heat of combustion of components of liquid hydrocarbon fuels ranging in volatility from that of light distillates to that of residual fuels. The ASTM D4809-18 method is similar to that of ASTM D240-19, though it specifically addresses the determination of net heat of combustion of aviation fuels with high precision.

                    <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 environmental justice concerns. For the HON, a total of 9.3 million people live within 10 km (~6.2 miles) of the 195 HON facilities that were assessed for risk. The percentages of the population that are Black (25 percent versus 12 percent) and Hispanic or Latino (22 percent versus 19 percent) are higher than the national averages. The proportion of other demographic groups living within 10 km of HON facilities is similar or lower than the national average. For the Neoprene Production source category, a total of 29,000 people live within 5 km of the one neoprene production facility in the country. The percent of the population that is Black (56 percent versus 12 percent) is substantially higher than the national average. The proportion of other demographic groups living within 10 km of HON facilities is similar or lower than the national average. The EPA also conducted a risk assessment of possible cancer risks and other adverse health effects, and found that prior to this final rule, cancer risks were above acceptable levels for a number of areas in which these demographic groups live for the SOCMI and Neoprene Production source categories. See section V.F for an analysis that characterizes populations living in proximity of facilities and risks prior to the final rule.</P>
                    <P>The EPA believes that this action is likely to reduce existing disproportionate and adverse effects on communities with environmental justice concerns. This action establishes standards for EtO emission sources at HON processes and chloroprene emission sources at neoprene production processes. This action also corrects and clarifies regulatory provisions related to emissions during periods of SSM, including removing general exemptions for periods of SSM and adding work practice standards for periods of SSM where appropriate, addressing flare combustion efficiency, and requiring fenceline monitoring for pollutants that drive cancer risks for HON and neoprene production sources. As a result of these changes, we expect zero people to be exposed to risk levels above 100-in-1 million due to emissions from each of these source categories. See section IV.A of this preamble for more information about the control requirements of the regulation and the resulting reduction in cancer risks.</P>
                    <P>
                        The EPA additionally identified and addressed environmental justice concerns by engaging in outreach activities to communities we expect to be impacted by chemical plants that emit EtO.

                                (a) Each owner or operator subject to the provisions of this subpart shall submit semiannual reports to the Administrator beginning six months after the initial startup date. Beginning on July 15, 2025, or once the report template for this subpart has been available on the CEDRI website (
                                <E T="03">https://www.epa.gov/electronic-reporting-air-emissions/cedri</E>
                                ) for 1 year, whichever date is later, submit all subsequent reports using the appropriate electronic report template on the CEDRI website for this subpart and following the procedure specified in paragraph (g) of this section. The date report templates become available will be listed on the CEDRI website. Unless the Administrator or delegated state agency or other authority has approved a different schedule for submission of reports, the report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted.

                                (f) The requirements of paragraphs (a) through (c) of this section remain in force until and unless EPA, in delegating enforcement authority to a State under section 111(c) of the Act, approves reporting requirements or an alternative means of compliance surveillance adopted by such State. In that event, affected sources within the State will be relieved of the obligation to comply with the requirements of paragraphs (a) through (c) of this section, provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the 
                                <PRTPAGE P="43069"/>
                                EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.
                            </P>
                            <P>
                                (g) If an owner or operator is required to submit notifications or reports following the procedure specified in this paragraph (g), the owner or operator must submit notifications or 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 the owner or operator. Do not use CEDRI to submit information the owner or operator claims as CBI. Although the EPA does not expect persons to assert a claim of CBI, if an owner or operator wishes to assert a CBI claim for some of the information in the report or notification, the owner or operator must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (g)(1) and (2) of this section. Clearly mark the part or all of the information claimed 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. The owner or operator must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (g).

                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                <E T="03">oaqpscbi@epa.gov</E>
                                , and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. Owners and operators who do not have their own file sharing service and who require assistance with submitting large electronic files that exceed the file size limit for email attachments should email 
                                <E T="03">oaqpscbi@epa.gov</E>
                                 to request a file transfer link.
                            </P>
                            <P>(2) If an owner or operator cannot transmit the file electronically, the owner or operator may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                            <P>(h) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of EPA system outage for failure to timely comply with that reporting requirement. To assert a claim of EPA system outage, owner and operator must meet the requirements outlined in paragraphs (h)(1) through (7) of this section.</P>
                            <P>(1) The owner or operator must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>

                            <P>(4) The owner or operator must submit notification to the Administrator in writing as soon as possible following the date the owner or operator first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting.</P>
                            <P>(5) The owner or operator must provide to the Administrator a written description identifying:</P>
                            <P>(i) The date(s) and time(s) when CDX or CEDRI was accessed and the system was unavailable;</P>

                                (i) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of

                            <P>(1) Method 21 shall be used to determine the presence of leaking sources. The instrument shall be calibrated before use each day of its use by the procedures specified in Method 21 of appendix A-7 of this part. The following calibration gases shall be used:</P>
                            <P>(i) Zero air (less than 10 ppm of hydrocarbon in air); and</P>
                            <P>
                                (ii) A mixture of methane or n-hexane and air at a concentration no more than 2,000 ppm greater than the leak definition concentration of the equipment monitored. If the monitoring instrument's design allows for multiple calibration scales, then the lower scale shall be calibrated with a calibration gas that is no higher than 2,000 ppm above the concentration specified as a leak, and the highest scale shall be calibrated 
                                <PRTPAGE P="43071"/>
                                with a calibration gas that is approximately equal to 10,000 ppm. If only one scale on an instrument will be used during monitoring, the owner or operator need not calibrate the scales that will not be used during that day's monitoring.
                            </P>
                            <P>(2) A calibration drift assessment shall be performed, at a minimum, at the end of each monitoring day. Check the instrument using the same calibration gas(es) that were used to calibrate the instrument before use. Follow the procedures specified in Method 21 of appendix A-7 to this part, section 10.1, except do not adjust the meter readout to correspond to the calibration gas value. Record the instrument reading for each scale used as specified in § 60.486a(e)(8). Divide the arithmetic difference of the initial and post-test calibration response by the corresponding calibration gas value for each scale and multiply by 100 to express the calibration drift as a percentage.</P>
                            <P>(i) If a calibration drift assessment shows a negative drift of more than 10 percent, then all equipment with instrument readings between the appropriate leak definition and the leak definition multiplied by (100 minus the percent of negative drift/divided by 100) that was monitored since the last calibration must be re-monitored.</P>
                            <P>(ii) If any calibration drift assessment shows a positive drift of more than 10 percent from the initial calibration value, then, at the owner/operator's discretion, all equipment with instrument readings above the appropriate leak definition and below the leak definition multiplied by (100 plus the percent of positive drift/divided by 100) monitored since the last calibration may be re-monitored.</P>

                                <PRTPAGE P="43072"/>
                                must submit notifications or 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 the owner or operator. Do not use CEDRI to submit information the owner or operator claims as CBI. Although the EPA does not expect persons to assert a claim of CBI, if you an owner or operator wishes to assert a CBI claim for some of the information in the report or notification, the owner or operator must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (g)(1) and (2) of this section. Clearly mark the part or all of the information claimed 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. The owner or operator must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (g).
                            </P>
                            <P>
                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                <E T="03">oaqpscbi@epa.gov</E>
                                , and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. Owners and operators who do not have their own file sharing service and who require assistance with submitting large electronic files that exceed the file size limit for email attachments should email 
                                <E T="03">oaqpscbi@epa.gov</E>
                                 to request a file transfer link.
                            </P>
                            <P>(2) If an owner or operator cannot transmit the file electronically, the owner or operator may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                            <P>(h) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of EPA system outage for failure to timely comply with that reporting requirement. To assert a claim of EPA system outage, owners and operators must meet the requirements outlined in paragraphs (h)(1) through (7) of this section.</P>
                            <P>(1) The owner or operator must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>
                            <P>(2) The outage must have occurred within the period of time beginning five business days prior to the date that the submission is due.</P>

                            <P>(4) The owner or operator must submit notification to the Administrator in writing as soon as possible following the date the owner or operator first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting.</P>
                            <P>(5) The owner or operator must provide to the Administrator a written description identifying:</P>
                            <P>(i) The date(s) and time(s) when CDX or CEDRI was accessed and the system was unavailable;</P>
                            <P>(ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to EPA system outage;</P>
                            <P>(iii) A description of measures taken or to be taken to minimize the delay in reporting; and</P>
                            <P>(iv) The date by which the owner or operator proposes to report, or if the owner or operator has already met the reporting requirement at the time of the notification, the date the report was submitted.</P>
                            <P>(6) The decision to accept the claim of EPA system outage and allow an extension to the reporting deadline is solely within the discretion of the Administrator.</P>
                            <P>(7) In any circumstance, the report must be submitted electronically as soon as possible after the outage is resolved.</P>
                            <P>
                                (i) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of

The required period in which monitoring must be conducted shall be determined from paragraphs (b)(3)(i) through (iii) of this section using the monitoring results from the preceding monitoring period. The percent leaking connectors shall be calculated as specified in paragraph (c) of this section.</P>
                            <P>(i) If the percent leaking connectors in the process unit was greater than or equal to 0.5 percent, then monitor within 12 months (1 year).</P>
                            <P>(ii) If the percent leaking connectors in the process unit was greater than or equal to 0.25 percent but less than 0.5 percent, then monitor within 4 years. An owner or operator may comply with the requirements of this paragraph by monitoring at least 40 percent of the connectors within 2 years of the start of the monitoring period, provided all connectors have been monitored by the end of the 4-year monitoring period.</P>
                            <P>(iii) If the percent leaking connectors in the process unit was less than 0.25 percent, then monitor as provided in paragraph (b)(3)(iii)(A) of this section and either paragraph (b)(3)(iii)(B) or (C) of this section, as appropriate.</P>
                            <P>(A) An owner or operator shall monitor at least 50 percent of the connectors within 4 years of the start of the monitoring period.</P>
                            <P>(B) If the percent of leaking connectors calculated from the monitoring results in paragraph (b)(3)(iii)(A) of this section is greater than or equal to 0.35 percent of the monitored connectors, the owner or operator shall monitor as soon as practical, but within the next 6 months, all connectors that have not yet been monitored during the monitoring period. At the conclusion of monitoring, a new monitoring period shall be started pursuant to paragraph (b)(3) of this section, based on the percent of leaking connectors within the total monitored connectors.</P>
                            <P>(C) If the percent of leaking connectors calculated from the monitoring results in paragraph (b)(3)(iii)(A) of this section is less than 0.35 percent of the monitored connectors, the owner or operator shall monitor all connectors that have not yet been monitored within 8 years of the start of the monitoring period.</P>
                            <P>(iv) If, during the monitoring conducted pursuant to paragraphs (b)(3)(i) through (iii) of this section, a connector is found to be leaking, it shall be re-monitored once within 90 days after repair to confirm that it is not leaking.</P>
                            <P>(v) The owner or operator shall keep a record of the start date and end date of each monitoring period under this section for each process unit.</P>

                            <P>(a) In conducting the performance tests required in § 60.8, the owner or operator shall use as reference methods and procedures the test methods in appendix A to this part or other methods and procedures as specified in this section, except as provided in § 60.8(b).</P>
                            <P>(b) The owner or operator shall determine compliance with the standards in §§ 60.482-1b through 60.482-11b, 60.483a, and 60.484b as follows:</P>
                            <P>(1) Method 21 of appendix A-7 to this part shall be used to determine the presence of leaking sources. The instrument shall be calibrated before use each day of its use by the procedures specified in Method 21. The following calibration gases shall be used:</P>
                            <P>(i) Zero air (less than 10 ppm of hydrocarbon in air); and</P>
                            <P>(ii) A mixture of methane or n-hexane and air at a concentration no more than 2,000 ppm greater than the leak definition concentration of the equipment monitored. If the monitoring instrument's design allows for multiple calibration scales, then the lower scale shall be calibrated with a calibration gas that is no higher than 2,000 ppm above the concentration specified as a leak, and the highest scale shall be calibrated with a calibration gas that is approximately equal to 10,000 ppm. If only one scale on an instrument will be used during monitoring, the owner or operator need not calibrate the scales that will not be used during that day's monitoring.</P>
                            <P>(2) A calibration drift assessment shall be performed, at a minimum, at the end of each monitoring day. Check the instrument using the same calibration gas(es) that were used to calibrate the instrument before use. Follow the procedures specified in Method 21 of appendix A-7 to this part, section 10.1, except do not adjust the meter readout to correspond to the calibration gas value. Record the instrument reading for each scale used as specified in § 60.486b(e)(8). Divide the arithmetic difference of the initial and post-test calibration response by the corresponding calibration gas value for each scale and multiply by 100 to express the calibration drift as a percentage.</P>
                            <P>(i) If a calibration drift assessment shows a negative drift of more than 10 percent, then all equipment with instrument readings between the appropriate leak definition and the leak definition multiplied by (100 minus the percent of negative drift/divided by 100) that was monitored since the last calibration must be re-monitored.</P>
                            <P>(ii) If any calibration drift assessment shows a positive drift of more than 10 percent from the initial calibration value, then, at the owner/operator's discretion, all equipment with instrument readings above the appropriate leak definition and below the leak definition multiplied by (100 plus the percent of positive drift/divided by 100) monitored since the last calibration may be re-monitored.</P>
                            <P>(c) The owner or operator shall determine compliance with the no-detectable-emission standards in §§ 60.482-2b(e), 60.482-3b(i), 60.482-4b, 60.482-7b(f), and 60.482-10b(e) as follows:</P>
                            <P>(1) The requirements of paragraph (b) shall apply.</P>
                            <P>(2) Method 21 of appendix A-7 to this part shall be used to determine the background level. All potential leak interfaces shall be traversed as close to the interface as possible. The arithmetic difference between the maximum concentration indicated by the instrument and the background level is compared with 500 ppm for determining compliance.</P>
                            <P>
                                (d) The owner or operator shall test each piece of equipment unless they demonstrate that a process unit is not in VOC service, 
                                <E T="03">i.e.,</E>
                                 that the VOC content would never be reasonably expected to exceed 10 percent by weight. For purposes of this demonstration, the following methods and procedures shall be used:
                            </P>
                            <P>(1) Procedures that conform to the general methods in ASTM E168-16 (Reapproved 2023), E169-16 (Reapproved 2022), or E260-96 (Reapproved 2019) (incorporated by reference, see § 60.17) shall be used to determine the percent VOC content in the process fluid that is contained in or contacts a piece of equipment.</P>
                            <P>(2) Organic compounds that are considered by the Administrator to have negligible photochemical reactivity may be excluded from the total quantity of organic compounds in determining the VOC content of the process fluid.</P>
                            <P>(3) Engineering judgment may be used to estimate the VOC content, if a piece of equipment had not been shown previously to be in service. If the Administrator disagrees with the judgment, paragraphs (d)(1) and (2) of this section shall be used to resolve the disagreement.</P>
                            <P>(e) The owner or operator shall demonstrate that a piece of equipment is in light liquid service by showing that all the following conditions apply:</P>

                            <P>(g) The owner or operator shall determine compliance with the standards of flares as follows:</P>
                            <P>(1) Method 22 of appendix A-7 to this part shall be used to determine visible emissions.</P>

The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.</P>
                            <P>
                                (g) If you are required to submit notifications or reports following the procedure specified in this paragraph (g), you must submit notifications or 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 CBI. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim for some of the information in the report or notification, you must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (g)(1) and (2) of this section. 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (g).
                            </P>
                            <P>
                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                <E T="03">oaqpscbi@epa.gov</E>
                                , and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email 
                                <E T="03">oaqpscbi@epa.gov</E>
                                 to request a file transfer link.
                            </P>
                            <P>(2) If you cannot transmit the file electronically, you may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                            <P>(h) If you are required to electronically submit notifications or reports through CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for failure to timely comply with that reporting requirement. To assert a claim of EPA system outage, you must meet the requirements outlined in paragraphs (h)(1) through (7) of this section.</P>
                            <P>(1) You must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>

Where a boiler or process heater with a design heat input capacity of 44 MW (150 million Btu/hour) or greater is used to comply with § 60.612(a), a report containing performance test data need not be submitted, but a report containing the information of § 60.615(b)(2)(i) is required. The same data specified in this section shall be submitted in the reports of all subsequently required performance tests where either the emission control efficiency of a control device, outlet concentration of TOC, or the TRE index value of a vent stream from a recovery system is determined. Beginning on July 15, 2024, owners and operators must submit the performance test report following the procedures specified in paragraph (m) of this section. Data collected using test methods that are supported by the EPA's Electronic Reporting Tool (ERT) as listed on the EPA's ERT website (

                                ) at the time of the test must be submitted in a file format generated using the EPA's ERT. Alternatively, the owner or operator may submit an electronic file consistent with the extensible markup language (XML) schema listed on the EPA's ERT website. Data collected using test methods that are not supported by the EPA's ERT as listed on the EPA's ERT website at the time of the test must be included as an attachment in the ERT or an alternate electronic file.

The initial report shall be submitted within 6 months after the initial start-up-date. On and after July 15, 2025 or once the report template for this subpart has been available on the Compliance and Emissions Data Reporting Interface (CEDRI) website (

The date report templates become available will be listed on the CEDRI website. Unless the Administrator or delegated state agency or other authority has approved a different schedule for submission of reports, the report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted.

In that event, affected sources within the State will be relieved of the obligation to comply with § 60.615(j), provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority.

                                (m) If an owner or operator is required to submit notifications or reports following the procedure specified in this paragraph (m), the owner or operator must submit notifications or 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 the owner or operator. Do not use CEDRI to submit information the owner or operator claims as CBI. Although the EPA does not expect persons to assert a claim of CBI, if an owner or operator wishes to assert a CBI claim for some of the information in the report or notification, the owner or operator must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (m)(1) and (2) of this section. Clearly mark the part or all of the information claimed 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. The owner or operator must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (m).

                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                <E T="03">oaqpscbi@epa.gov</E>
                                , and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. Owners and operators who do not have their own file sharing service and who require assistance with submitting large electronic files that exceed the file size limit for email attachments should email 
                                <E T="03">oaqpscbi@epa.gov</E>

                            <P>(2) If an owner or operator cannot transmit the file electronically, the owner or operator may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>

                                <P>(c) You may designate a vent stream as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. You must comply with the applicable requirements in paragraphs (c)(1) through (3) of this section for each maintenance vent. Any vent stream designated as a maintenance vent is only subject to the maintenance vent provisions in this paragraph (c) and the associated recordkeeping and reporting requirements in § 60.615a(g), respectively.</P>
                                <P>(1) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements of § 60.619a, as applicable, or using any combination of a non-flare control device or recovery device meeting the requirements in Table 1 to this subpart until one of the following conditions, as applicable, is met.</P>

During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.</P>
                                <P>(2) Except for maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine the LEL or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.</P>
                                <P>(3) For maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.</P>

For each period, the report must include a list of the affected facilities or equipment, the start date and time of the period, the duration (in hours) of the period, the cause of the inoperability (including unknown cause, if applicable), as applicable, and the corrective action taken.</P>
                                <P>(8) Any change in equipment or process operation that increases the operating vent stream flow rate above the low flow exemption level in § 60.610a(c)(1), including a measurement of the new vent stream flow rate, as recorded under paragraph (h) of this section. These must be reported as soon as possible after the change and no later than 180 days after the change. These reports may be submitted either in conjunction with semiannual reports or as a single separate report. A performance test must be completed with the same time period to verify the recalculated flow value. The performance test is subject to the requirements of § 60.8 of the General Provisions and must be submitted according to paragraph (b)(1) of this section. Unless the facility qualifies for an exemption under § 60.610a(c), the facility must begin compliance with the requirements set forth in § 60.612a.</P>
                                <P>
                                    (j) If you are required to submit notifications or reports following the procedure specified in this paragraph (j), you must submit notifications or reports to the EPA via the 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 CBI. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim for some of the information in the report or notification, you must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (j)(1) and (2) of this section. 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (j).
                                </P>
                                <P>
                                    (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                    <E T="03">oaqpscbi@epa.gov,</E>
                                     and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. If assistance is needed with submitting large electronic files that exceed the file size limit for email attachments, and if you do not have your own file sharing service, please email 
                                    <E T="03">oaqpscbi@epa.gov</E>

                                <P>(2) If you cannot transmit the file electronically, you may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                                <P>(k) If you are required to electronically submit notifications or reports through CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for failure to timely comply with the electronic submittal requirement. To assert a claim of EPA system outage, you must meet the requirements outlined in paragraphs (k)(1) through (7) of this section.</P>
                                <P>(1) You must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>
                                <P>(2) The outage must have occurred within the period of time beginning five business days prior to the date that the submission is due.</P>

                                <P>(6) The decision to accept the claim of EPA system outage and allow an extension to the reporting deadline is solely within the discretion of the Administrator.</P>
                                <P>(7) In any circumstance, the report must be submitted electronically as soon as possible after the outage is resolved.</P>
                                <P>
                                    (l) If you are required to electronically submit notifications or reports through CEDRI in the EPA's CDX, you may assert a claim of

                                     for failure to timely comply with the electronic submittal requirement. To assert a claim of 
                                    <E T="03">force majeure,</E>
                                     you must meet the requirements outlined in paragraphs (l)(1) through (5) of this section.
                                </P>
                                <P>
                                    (1) You may submit a claim if a 
                                    <E T="03">force majeure</E>

                                     event is defined as an event that will be or has been caused by circumstances beyond the control of the affected facility, its contractors, or any entity controlled by the affected facility that prevents you from complying with the requirement to submit a report electronically within the time period prescribed. Examples of such events are acts of nature (
                                    <E T="03">e.g.,</E>
                                     hurricanes, earthquakes, or floods), acts of war or terrorism, or equipment failure or safety hazard beyond the control of the affected facility (

                                <P>(2) You must submit notification to the Administrator in writing as soon as possible following the date you first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting.</P>
                                <P>(3) You must provide to the Administrator:</P>

                                    (ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to the 
                                    <E T="03">force majeure</E>
                                     event;

                                <P>
                                    (5) In any circumstance, the reporting must occur as soon as possible after the 
                                    <E T="03">force majeure</E>
                                     event occurs.

                                <P>(m) The requirements of paragraph (i) of this section remain in force until and unless EPA, in delegating enforcement authority to a State under section 111(c) of the Act, approves reporting requirements or an alternative means of compliance surveillance adopted by such State. In that event, affected sources within the State will be relieved of the obligation to comply with paragraph (i) of this section, provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.</P>
                                <P>(n) If you seek to demonstrate compliance with § 60.610(c)(1), then you must submit to the Administrator, following the procedures in paragraph (b)(1) of this section, an initial report including a flow rate measurement using the test methods specified in § 60.614a.</P>
                                <P>(o) The Administrator will specify appropriate reporting and recordkeeping requirements where the owner or operator of an affected facility seeks to demonstrate compliance with the standards specified under § 60.612a other than as provided under § 60.613a.</P>
                                <P>(p) Any records required to be maintained by this subpart that are submitted electronically via the EPA's CEDRI may be maintained in electronic format. This ability to maintain electronic copies does not affect the requirement for facilities to make records, data, and reports available upon request to a delegated air agency or the EPA as part of an on-site compliance evaluation.</P>

                                <SUBJECT>What are my requirements if I use a flare to comply with this subpart?</SUBJECT>
                                <P>(a) If you use a flare to comply with the TOC emission standard specified in Table 1 to this subpart, then you must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671 of this chapter, including the provisions in tables 12 and 13 to part 63, subpart CC, of this chapter, except as specified in paragraphs (b) through (o) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from an affected facility, as determined on an annual average basis. For purposes of compliance with this paragraph (a), the following terms are defined in § 63.641 of this chapter: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.</P>
                                <P>(b) When determining compliance with the pilot flame requirements specified in § 63.670(b) and (g) of this chapter, substitute “pilot flame or flare flame” for each occurrence of “pilot flame.”</P>
                                <P>
                                    (c) When determining compliance with the flare tip velocity and combustion zone operating limits specified in § 63.670(d) and (e) of this chapter, the requirement effectively applies starting with the 15-minute 
                                    <PRTPAGE P="43099"/>
                                    block that includes a full 15 minutes of the flaring event. You are required to demonstrate compliance with the velocity and NHVcz requirements starting with the block that contains the fifteenth minute of a flaring event. You are not required to demonstrate compliance for the previous 15-minute block in which the event started and contained only a fraction of flow.
                                </P>
                                <P>(d) Instead of complying with § 63.670(o)(2)(i) of this chapter, you must develop and implement the flare management plan no later than startup for a new flare that commenced construction on or after April 25, 2023.</P>
                                <P>(e) Instead of complying with § 63.670(o)(2)(iii) of this chapter, if required to develop a flare management plan and submit it to the Administrator, then you must also submit all versions of the plan in portable document format (PDF) following the procedures specified in § 60.615a(j).</P>
                                <P>(f) Section 63.670(o)(3)(ii) of this chapter and all references to it do not apply. Instead, you must comply with the maximum flare tip velocity operating limit at all times.</P>
                                <P>(g) Substitute “affected facility” for each occurrence of “petroleum refinery.”</P>
                                <P>(h) Each occurrence of “refinery” does not apply.</P>
                                <P>(i) If a pressure-assisted multi-point flare is used as a control device, then you must meet the following conditions:</P>
                                <P>(1) You are not required to comply with the flare tip velocity requirements in of § 63.670(d) and (k) of this chapter;</P>
                                <P>(2) The NHVcz for pressure-assisted mulit-point flares is 800 Btu/scf;</P>
                                <P>(3) You must determine the 15-minute block average NHVvg using only the direct calculation method specified in in § 63.670 (l)(5)(ii) of this chapter;</P>
                                <P>(4) Instead of complying with § 63.670(b) and (g) of this chapter, if a pressure-assisted multi-point flare uses cross-lighting on a stage of burners rather than having an individual pilot flame on each burner, then you must operate each stage of the pressure-assisted multi-point flare with a flame present at all times when regulated material is routed to that stage of burners. Each stage of burners that cross-lights in the pressure-assisted multi-point flare must have at least two pilots with at least one continuously lit and capable of igniting all regulated material that is routed to that stage of burners. Each 15-minute block during which there is at least one minute where no pilot flame is present on a stage of burners when regulated material is routed to the flare is a deviation of the standard. Deviations in different 15-minute blocks from the same event are considered separate deviations. The pilot flame(s) on each stage of burners that use cross-lighting must be continuously monitored by a thermocouple or any other equivalent device used to detect the presence of a flame;</P>
                                <P>
                                    (5) Unless you choose to conduct a cross-light performance demonstration as specified in this paragraph (i)(5), you must ensure that if a stage of burners on the flare uses cross-lighting, that the distance between any two burners in series on that stage is no more than 6 feet when measured from the center of one burner to the next burner. A distance greater than 6 feet between any two burners in series may be used provided you conduct a performance demonstration that confirms the pressure-assisted multi-point flare will cross-light a minimum of three burners and the spacing between the burners and location of the pilot flame must be representative of the projected installation. The compliance demonstration must be approved by the permitting authority and a copy of this approval must be maintained onsite. The compliance demonstration report must include: a protocol describing the test methodology used, associated test method QA/QC parameters, the waste gas composition and NHVcz of the gas tested, the velocity of the waste gas tested, the pressure-assisted multi-point flare burner tip pressure, the time, length, and duration of the test, records of whether a successful cross-light was observed over all of the burners and the length of time it took for the burners to cross-light, records of maintaining a stable flame after a successful cross-light and the duration for which this was observed, records of any smoking events during the cross-light, waste gas temperature, meteorological conditions (
                                    <E T="03">e.g.,</E>
                                     ambient temperature, barometric pressure, wind speed and direction, and relative humidity), and whether there were any observed flare flameouts; and
                                </P>
                                <P>(6) You must install and operate pressure monitor(s) on the main flare header, as well as a valve position indicator monitoring system for each staging valve to ensure that the flare operates within the proper range of conditions as specified by the manufacturer. The pressure monitor must meet the requirements in table 13 to part 63, subpart CC of this chapter.</P>
                                <P>(7) If a pressure-assisted multi-point flare is operating under the requirements of an approved alternative means of emission limitations, you must either continue to comply with the terms of the alternative means of emission limitations or comply with the provisions in paragraphs (i)(1) through (6) of this section.</P>
                                <P>(j) If you choose to determine compositional analysis for net heating value with a continuous process mass spectrometer, then you must comply with the requirements specified in paragraphs (j)(1) through (7) of this section.</P>
                                <P>(1) You must meet the requirements in § 63.671(e)(2) of this chapter. You may augment the minimum list of calibration gas components found in § 63.671(e)(2) with compounds found during a pre-survey or known to be in the gas through process knowledge.</P>
                                <P>(2) Calibration gas cylinders must be certified to an accuracy of 2 percent and traceable to National Institute of Standards and Technology (NIST) standards.</P>
                                <P>(3) For unknown gas components that have similar analytical mass fragments to calibration compounds, you may report the unknowns as an increase in the overlapped calibration gas compound. For unknown compounds that produce mass fragments that do not overlap calibration compounds, you may use the response factor for the nearest molecular weight hydrocarbon in the calibration mix to quantify the unknown component's NHVvg.</P>
                                <P>(4) You may use the response factor for n-pentane to quantify any unknown components detected with a higher molecular weight than n-pentane.</P>
                                <P>(5) You must perform an initial calibration to identify mass fragment overlap and response factors for the target compounds.</P>
                                <P>(6) You must meet applicable requirements in Performance Specification 9 of appendix B of this part, for continuous monitoring system acceptance including, but not limited to, performing an initial multi-point calibration check at three concentrations following the procedure in section 10.1 and performing the periodic calibration requirements listed for gas chromatographs in table 13 to part 63, subpart CC of this chapter, for the process mass spectrometer.

                                <P>(b) You must inspect each closed vent system according to the procedures specified in paragraphs (b)(1) through (6) of this section.</P>
                                <P>(1) Inspections must be conducted in accordance with Method 21 of appendix A of this part.</P>
                                <P>(2)(i) Except as provided in paragraph (b)(2)(ii) of this section, the detection instrument must meet the performance criteria of Method 21 of appendix A of this part, except the instrument response factor criteria in section 3.1.2(a) of Method 21 must be for the average composition of the process fluid not each individual volatile organic compound in the stream. For process streams that contain nitrogen, air, or other inerts which are not organic hazardous air pollutants or volatile organic compounds, the average stream response factor must be calculated on an inert-free basis.</P>
                                <P>(ii) If no instrument is available at the plant site that will meet the performance criteria specified in paragraph (b)(2)(i) of this section, the instrument readings may be adjusted by multiplying by the average response factor of the process fluid, calculated on an inert-free basis as described in paragraph (b)(2)(i) of this section.</P>
                                <P>(3) The detection instrument must be calibrated before use on each day of its use by the procedures specified in Method 21 of appendix A of this part.</P>

                                <P>(ii) Mixtures of methane in air at a concentration less than 2,000 parts per million. A calibration gas other than methane in air may be used if the instrument does not respond to methane or if the instrument does not meet the performance criteria specified in paragraph (b)(2)(i) of this section. In such cases, the calibration gas may be a mixture of one or more of the compounds to be measured in air.</P>
                                <P>(5) You may elect to adjust or not adjust instrument readings for background. If you elect to not adjust readings for background, all such instrument readings must be compared directly to the applicable leak definition to determine whether there is a leak.</P>
                                <P>(6) If you elect to adjust instrument readings for background, you must determine the background concentration using Method 21 of appendix A of this part. After monitoring each potential leak interface, subtract the background reading from the maximum concentration indicated by the instrument. The arithmetic difference between the maximum concentration indicated by the instrument and the background level must be compared with 500 parts per million for determining compliance.</P>
                                <P>(c) Leaks, as indicated by an instrument reading greater than 500 parts per million above background or by visual, audio, or olfactory inspections, must be repaired as soon as practicable, except as provided in paragraph (d) of this section.</P>
                                <P>(1) A first attempt at repair must be made no later than 5 calendar days after the leak is detected.</P>
                                <P>(2) Repair must be completed no later than 15 calendar days after the leak is detected.</P>
                                <P>(d) Delay of repair of a closed vent system for which leaks have been detected is allowed if the repair is technically infeasible without a shutdown, as defined in § 60.2, or if you determine that emissions resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair. Repair of such equipment must be complete by the end of the next shutdown.</P>
                                <P>(e) For each closed vent system that contains bypass lines that could divert a vent stream away from the control device and to the atmosphere, you must comply with the provisions of either paragraph (e)(1) or (2), except as specified in paragraph (e)(3) of this section.</P>
                                <P>(1) Install, calibrate, maintain, and operate a flow indicator that determines whether vent stream flow is present at least once every 15 minutes. You must keep hourly records of whether the flow indicator was operating and whether a diversion was detected at any time during the hour, as well as records of the times and durations of all periods when the vent stream is diverted to the atmosphere or the flow indicator is not operating.

In that event, affected sources within the State will be relieved of the obligation to comply with § 60.665(l), provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority.

                                (q) If an owner or operator is required to submit notifications or reports following the procedure specified in this paragraph (q), the owner or operator must submit notifications or reports to the EPA via CEDRI, which can be accessed through the EPA's Central Data Exchange (CDX) (

                                ). The EPA will make all the information submitted through CEDRI available to the public without further notice to the owner or operator. Do not use CEDRI to submit information the owner or operator claims as CBI. Although the EPA does not expect persons to assert a claim of CBI, if an owner or operator wishes to assert a CBI claim for some of the information in the report or notification, the owner or operator must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (q)(1) and (2) of this section. Clearly mark the part or all of the information that claimed 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. The owner or operator must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (q).

                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address

                                , and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. Owners and operators who do not have their own file sharing service and who require assistance with submitting large electronic files that exceed the file size limit for email attachments should email 
                                <E T="03">oaqpscbi@epa.gov</E>

                                <P>(c) You may designate a vent stream as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. You must comply with the applicable requirements in paragraphs (c)(1) through (3) of this section for each maintenance vent. Any vent stream designated as a maintenance vent is only subject to the maintenance vent provisions in this paragraph (c) and the associated recordkeeping and reporting requirements in § 60.665a(g), respectively.</P>
                                <P>(1) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements of § 60.669a, as applicable, or using any combination of a non-flare control device or recovery device meeting the requirements in table 1 to this subpart until one of the following conditions, as applicable, is met.</P>
                                <P>(i) The vapor in the equipment served by the maintenance vent has a lower explosive limit (LEL) of less than 10 percent.</P>
                                <P>(ii) If there is no ability to measure the LEL of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the LEL of the vapors in the maintenance vent (or inside the equipment if the maintenance vent is a hatch or similar type of opening) is less than 10 percent.</P>
                                <P>(iii) The equipment served by the maintenance vent contains less than 50 pounds of total VOC.</P>
                                <P>(iv) If, after applying best practices to isolate and purge equipment served by a maintenance vent, none of the applicable criterion in paragraphs (c)(1)(i) through (iii) of this section can be met prior to installing or removing a blind flange or similar equipment blind, then the pressure in the equipment served by the maintenance vent must be reduced to 2 psig or less before installing or removing the equipment blind. During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.</P>
                                <P>(2) Except for maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine the LEL or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.</P>
                                <P>(3) For maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.</P>

A performance test must be completed with the same time period to verify the recalculated flow value. The performance test is subject to the requirements of § 60.8 and must be submitted according to paragraph (b)(1) of this section. Unless the facility qualifies for an exemption under § 60.660a(c), the facility must begin compliance with the requirements set forth in § 60.662a.</P>
                                <P>(8) Exceedances of the emission standard in Table 1 of this subpart as indicated by a 3-hour average of the TOC CEMS and recorded under paragraph (c) of this section. For each exceedance, the report must include a list of the affected facilities or equipment, the start date and time of the exceedance, the duration (in hours) of the exceedance, an estimate of the quantity in pounds of each regulated pollutant emitted over the emission limit, a description of the method used to estimate the emissions, the cause of the exceedance (including unknown cause, if applicable), as applicable, and the corrective action taken.</P>
                                <P>(9) Periods when the TOC CEMS was inoperative. For each period, the report must include a list of the affected facilities or equipment, the start date and time of the period, the duration (in hours) of the period, the cause of the inoperability (including unknown cause, if applicable), as applicable, and the corrective action taken.</P>
                                <P>
                                    (k) If you are required to submit notifications or reports following the procedure specified in this paragraph (k), you must submit notifications or 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 CBI. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim for some of the information in the report or notification, you must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (k)(1) and (2) of this section. 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (k).

                                <P>
                                    (1) The preferred method to receive CBI is for it to be transmitted 
                                    <PRTPAGE P="43117"/>
                                    electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                    <E T="03">oaqpscbi@epa.gov,</E>
                                     and as described above, should include clear CBI markings.

                                <P>(2) If you cannot transmit the file electronically, you may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                                <P>(l) If you are required to electronically submit notifications or reports through CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for failure to timely comply with the electronic submittal requirement. To assert a claim of EPA system outage, you must meet the requirements outlined in paragraphs (l)(1) through (7) of this section.</P>
                                <P>(1) You must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>

                                <P>(5) You must provide to the Administrator a written description identifying:</P>
                                <P>(i) The date(s) and time(s) when CDX or CEDRI was accessed and the system was unavailable;</P>
                                <P>(ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to EPA system outage;</P>

                                    (m) If you are required to electronically submit notifications or reports through CEDRI in the EPA's CDX, you may assert a claim of 
                                    <E T="03">force majeure</E>
                                     for failure to timely comply with the electronic submittal requirement. To assert a claim of 
                                    <E T="03">force majeure,</E>
                                     you must meet the requirements outlined in paragraphs (m)(1) through (5) of this section.

                                <P>
                                    (1) You may submit a claim if a

                                     event is about to occur, occurs, or has occurred or there are lingering effects from such an event within the period of time beginning five business days prior to the date the submission is due. For the purposes of this section, a 
                                    <E T="03">force majeure</E>
                                     event is defined as an event that will be or has been caused by circumstances beyond the control of the affected facility, its contractors, or any entity controlled by the affected facility that prevents you from complying with the requirement to submit a report electronically within the time period prescribed. Examples of such events are acts of nature (
                                    <E T="03">e.g.,</E>
                                     hurricanes, earthquakes, or floods), acts of war or terrorism, or equipment failure or safety hazard beyond the control of the affected facility (

                                <P>(2) You must submit notification to the Administrator in writing as soon as possible following the date you first knew, or through due diligence should have known, that the event may cause or has caused a delay in reporting.</P>
                                <P>(3) You must provide to the Administrator:</P>

                                     event;
                                </P>

                                    (ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to the 
                                    <E T="03">force majeure</E>
                                     event;

                                    (5) In any circumstance, the reporting must occur as soon as possible after the 
                                    <E T="03">force majeure</E>
                                     event occurs.

                                <P>(n) The requirements of paragraph (j) of this section remain in force until and unless EPA, in delegating enforcement authority to a State under section 111(c) of the Act, approves reporting requirements or an alternative means of compliance surveillance adopted by such State. In that event, affected sources within the State will be relieved of the obligation to comply with paragraph (j) of this section, provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.</P>
                                <P>(o) If you seek to demonstrate compliance with § 60.660(c)(4), then you must submit to the Administrator an initial report detailing the design production capacity of the process unit.</P>
                                <P>(p) If you seek to demonstrate compliance with § 60.660(c)(5) or (6), then you must submit to the Administrator, following the procedures in paragraph (b)(1) of this section, an initial report including a flow rate measurement using the test methods specified in § 60.664a.</P>
                                <P>(q) The Administrator will specify appropriate reporting and recordkeeping requirements where the owner or operator of an affected facility complies with the standards specified under § 60.662a other than as provided under § 60.663a.</P>
                                <P>(r) Any records required to be maintained by this subpart that are submitted electronically via the EPA's CEDRI may be maintained in electronic format. This ability to maintain electronic copies does not affect the requirement for facilities to make records, data, and reports available upon request to a delegated air agency or the EPA as part of an on-site compliance evaluation.</P>

                                <SUBJECT>What are my requirements if I use a flare to comply with this subpart?</SUBJECT>
                                <P>(a) If you use a flare to comply with the TOC emission standard specified in Table 1 to this subpart, then you must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671 of this chapter, including the provisions in tables 12 and 13 to part 63, subpart CC, of this chapter, except as specified in paragraphs (b) through (o) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from an affected facility, as determined on an annual average basis. For purposes of compliance with this paragraph (a), the following terms are defined in § 63.641 of this chapter: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.</P>
                                <P>(b) When determining compliance with the pilot flame requirements specified in § 63.670(b) and (g) of this chapter, substitute “pilot flame or flare flame” for each occurrence of “pilot flame.”</P>
                                <P>(c) When determining compliance with the flare tip velocity and combustion zone operating limits specified in § 63.670(d) and (e) of this chapter, the requirement effectively applies starting with the 15-minute block that includes a full 15 minutes of the flaring event. You are required to demonstrate compliance with the velocity and NHVcz requirements starting with the block that contains the fifteenth minute of a flaring event. You are not required to demonstrate compliance for the previous 15-minute block in which the event started and contained only a fraction of flow.</P>
                                <P>(d) Instead of complying with § 63.670(o)(2)(i) of this chapter, you must develop and implement the flare management plan no later than startup for a new flare that commenced construction on or after April 25, 2023.</P>
                                <P>(e) Instead of complying with § 63.670(o)(2)(iii) of this chapter, if required to develop a flare management plan and submit it to the Administrator, then you must also submit all versions of the plan in portable document format (PDF) following the procedures specified in § 60.665a(k).</P>
                                <P>(f) Section 63.670(o)(3)(ii) of this chapter and all references to it do not apply. Instead, you must comply with the maximum flare tip velocity operating limit at all times.</P>
                                <P>(g) Substitute “affected facility” for each occurrence of “petroleum refinery.”</P>
                                <P>(h) Each occurrence of “refinery” does not apply.</P>
                                <P>(i) If a pressure-assisted multi-point flare is used as a control device, then you must meet the following conditions:</P>
                                <P>(1) You are not required to comply with the flare tip velocity requirements in § 63.670(d) and (k) of this chapter;</P>
                                <P>(2) The NHVcz for pressure-assisted mulit-point flares is 800 Btu/scf;</P>
                                <P>(3) You must determine the 15-minute block average NHVvg using only the direct calculation method specified in in § 63.670(l)(5)(ii) of this chapter;</P>
                                <P>(4) Instead of complying with § 63.670(b) and (g) of this chapter, if a pressure-assisted multi-point flare uses cross-lighting on a stage of burners rather than having an individual pilot flame on each burner, then you must operate each stage of the pressure-assisted multi-point flare with a flame present at all times when regulated material is routed to that stage of burners. Each stage of burners that cross-lights in the pressure-assisted multi-point flare must have at least two pilots with at least one continuously lit and capable of igniting all regulated material that is routed to that stage of burners. Each 15-minute block during which there is at least one minute where no pilot flame is present on a stage of burners when regulated material is routed to the flare is a deviation of the standard. Deviations in different 15-minute blocks from the same event are considered separate deviations. The pilot flame(s) on each stage of burners that use cross-lighting must be continuously monitored by a thermocouple or any other equivalent device used to detect the presence of a flame;</P>
                                <P>
                                    (5) Unless you choose to conduct a cross-light performance demonstration as specified in this paragraph (i)(5), you must ensure that if a stage of burners on the flare uses cross-lighting, that the distance between any two burners in series on that stage is no more than 6 feet when measured from the center of one burner to the next burner. A distance greater than 6 feet between any two burners in series may be used provided you conduct a performance demonstration that confirms the pressure-assisted multi-point flare will cross-light a minimum of three burners and the spacing between the burners and location of the pilot flame must be representative of the projected installation. The compliance demonstration must be approved by the permitting authority and a copy of this approval must be maintained onsite. The compliance demonstration report must include: a protocol describing the test methodology used, associated test method QA/QC parameters, the waste gas composition and NHVcz of the gas tested, the velocity of the waste gas tested, the pressure-assisted multi-point flare burner tip pressure, the time, length, and duration of the test, records of whether a successful cross-light was observed over all of the burners and the length of time it took for the burners to cross-light, records of maintaining a stable flame after a successful cross-light and the duration for which this was observed, records of any smoking events during the cross-light, waste gas temperature, meteorological conditions (

                                <P>(6) You must install and operate pressure monitor(s) on the main flare header, as well as a valve position indicator monitoring system for each staging valve to ensure that the flare operates within the proper range of conditions as specified by the manufacturer. The pressure monitor must meet the requirements in table 13 to part 63, subpart CC, of this chapter.</P>
                                <P>(7) If a pressure-assisted multi-point flare is operating under the requirements of an approved alternative means of emission limitations, you must either continue to comply with the terms of the alternative means of emission limitations or comply with the provisions in paragraphs (i)(1) through (6) of this section.</P>

                                <P>(3) For unknown gas components that have similar analytical mass fragments to calibration compounds, you may report the unknowns as an increase in the overlapped calibration gas compound. For unknown compounds that produce mass fragments that do not overlap calibration compounds, you may use the response factor for the nearest molecular weight hydrocarbon in the calibration mix to quantify the unknown component's NHVvg.</P>
                                <P>(4) You may use the response factor for n-pentane to quantify any unknown components detected with a higher molecular weight than n-pentane.</P>
                                <P>(5) You must perform an initial calibration to identify mass fragment overlap and response factors for the target compounds.</P>

                                <P>(2) Conduct annual inspections according to the procedures in paragraph (b) of this section unless the closed vent system is operated and maintained under negative pressure; and</P>
                                <P>(3) Conduct annual inspections for visible, audible, or olfactory indications of leaks.</P>
                                <P>(b) You must inspect each closed vent system according to the procedures specified in paragraphs (b)(1) through (6) of this section.</P>
                                <P>(1) Inspections must be conducted in accordance with Method 21 of appendix A of this part.</P>
                                <P>(2)(i) Except as provided in paragraph (b)(2)(ii) of this section, the detection instrument must meet the performance criteria of Method 21 of appendix A of this part, except the instrument response factor criteria in section 3.1.2(a) of Method 21 must be for the average composition of the process fluid not each individual volatile organic compound in the stream. For process streams that contain nitrogen, air, or other inerts which are not organic hazardous air pollutants or volatile organic compounds, the average stream response factor must be calculated on an inert-free basis.</P>
                                <P>(ii) If no instrument is available at the plant site that will meet the performance criteria specified in paragraph (b)(2)(i) of this section, the instrument readings may be adjusted by multiplying by the average response factor of the process fluid, calculated on an inert-free basis as described in paragraph (b)(2)(i).</P>
                                <P>(3) The detection instrument must be calibrated before use on each day of its use by the procedures specified in Method 21 of appendix A of this part.</P>
                                <P>(4) Calibration gases must be as follows:</P>
                                <P>(i) Zero air (less than 10 parts per million hydrocarbon in air); and</P>
                                <P>(ii) Mixtures of methane in air at a concentration less than 2,000 parts per million. A calibration gas other than methane in air may be used if the instrument does not respond to methane or if the instrument does not meet the performance criteria specified in paragraph (b)(2)(i) of this section. In such cases, the calibration gas may be a mixture of one or more of the compounds to be measured in air.</P>
                                <P>(5) You may elect to adjust or not adjust instrument readings for background. If you elect to not adjust readings for background, all such instrument readings must be compared directly to the applicable leak definition to determine whether there is a leak.</P>
                                <P>(6) If you elect to adjust instrument readings for background, you must determine the background concentration using Method 21 of appendix A of this part. After monitoring each potential leak interface, subtract the background reading from the maximum concentration indicated by the instrument. The arithmetic difference between the maximum concentration indicated by the instrument and the background level must be compared with 500 parts per million for determining compliance.</P>
                                <P>(c) Leaks, as indicated by an instrument reading greater than 500 parts per million above background or by visual, audio, or olfactory inspections, must be repaired as soon as practicable, except as provided in paragraph (d) of this section.</P>
                                <P>(1) A first attempt at repair must be made no later than 5 calendar days after the leak is detected.</P>
                                <P>(2) Repair must be completed no later than 15 calendar days after the leak is detected.</P>
                                <P>(d) Delay of repair of a closed vent system for which leaks have been detected is allowed if the repair is technically infeasible without a shutdown, as defined in § 60.2, or if you determine that emissions resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair. Repair of such equipment must be complete by the end of the next shutdown.</P>
                                <P>(e) For each closed vent system that contains bypass lines that could divert a vent stream away from the control device and to the atmosphere, you must comply with the provisions of either paragraph (e)(1) or (2), except as specified in paragraph (e)(3) of this section.</P>
                                <P>(1) Install, calibrate, maintain, and operate a flow indicator that determines whether vent stream flow is present at least once every 15 minutes. You must keep hourly records of whether the flow indicator was operating and whether a diversion was detected at any time during the hour, as well as records of the times and durations of all periods when the vent stream is diverted to the atmosphere or the flow indicator is not operating. The flow indicator must be installed at the entrance to any bypass line; or</P>
                                <P>(2) Secure the bypass line valve in the closed position with a car-seal or a lock-and-key type configuration. A visual inspection of the seal or closure mechanism must be performed at least once every month to ensure the valve is maintained in the closed position and the vent stream is not diverted through the bypass line.</P>
                                <P>(3) Open-ended valves or lines that use a cap, blind flange, plug, or second valve and follow the requirements specified in § 60.482-6(a)(2), (b), and (c) or follow requirements codified in another regulation that are the same as § 60.482-6(a)(2), (b), and (c) are not subject to this paragraph (e) of this section.</P>
                                <P>(f) Any parts of the closed vent system that are designated, as described in paragraph (h)(1) of this section, as unsafe to inspect are exempt from the inspection requirements of paragraphs (a)(1) and (2) of this section if:</P>
                                <P>(1) You determine that the equipment is unsafe to inspect because inspecting personnel would be exposed to an imminent or potential danger as a consequence of complying with paragraphs (a)(1) and (2) of this section; and</P>
                                <P>(2) You have a written plan that requires inspection of the equipment as frequently as practicable during safe-to-inspect times.</P>
                                <P>(g) Any parts of the closed vent system are designated, as described in paragraph (h)(2) of this section, as difficult to inspect are exempt from the inspection requirements of paragraphs (a)(1) and (2) of this section if:</P>
                                <P>(1) You determine that the equipment cannot be inspected without elevating the inspecting personnel more than 2 meters above a support surface; and</P>
                                <P>(2) You have a written plan that requires inspection of the equipment at least once every 5 years.</P>
                                <P>(h) You must record the information specified in paragraphs (h)(1) through (5) of this section.</P>
                                <P>(1) Identification of all parts of the closed vent system that are designated as unsafe to inspect, an explanation of why the equipment is unsafe to inspect, and the plan for inspecting the equipment.</P>
                                <P>(2) Identification of all parts of the closed vent system that are designated as difficult to inspect, an explanation of why the equipment is difficult to inspect, and the plan for inspecting the equipment.</P>
                                <P>
                                    (3) For each closed vent system that contains bypass lines that could divert a vent stream away from the control device and to the atmosphere, you must keep a record of the information specified in either paragraph (h)(3)(i) or (ii) of this section in addition to the 
                                    <PRTPAGE P="43125"/>
                                    information specified in paragraph (h)(3)(iii) of this section.

                                <P>(ii) Where a seal mechanism is used to comply with paragraph (e)(2) of this section, hourly records of flow are not required. In such cases, you must record whether the monthly visual inspection of the seals or closure mechanisms has been done, and you must record the occurrence of all periods when the seal mechanism is broken, the bypass line valve position has changed, or the key for a lock-and-key type configuration has been checked out, and records of any car-seal that has broken.</P>
                                <P>(iii) For each flow event from a bypass line subject to the requirements in paragraph (e) of this section, you must maintain records sufficient to determine whether or not the detected flow included flow requiring control. For each flow event from a bypass line requiring control that is released either directly to the atmosphere or to a control device not meeting the requirements in this subpart, you must include an estimate of the volume of gas, the concentration of VOC in the gas and the resulting emissions of VOC that bypassed the control device using process knowledge and engineering estimates.</P>
                                <P>(4) For each inspection during which a leak is detected, a record of the information specified in paragraphs (h)(4)(i) through (viii) of this section.</P>

                                <P>(viii) The date of successful repair of the leak.</P>
                                <P>(5) For each inspection conducted in accordance with paragraph (b) of this section during which no leaks are detected, a record that the inspection was performed, the date of the inspection, and a statement that no leaks were detected.</P>
                                <P>(6) For each inspection conducted in accordance with paragraph (a)(3) of this section during which no leaks are detected, a record that the inspection was performed, the date of the inspection, and a statement that no leaks were detected.</P>
                                <P>(i) The semiannual report specified in § 60.665a(j)(5) must include the items specified in paragraphs (i)(1) through (3) of this section.</P>
                                <P>(1) Reports of the times of all periods recorded under paragraph (h)(3)(i) of this section when the vent stream is diverted from the control device through a bypass line. Include the start date, start time, and duration in hours of each period.</P>
                                <P>(2) Reports of all periods recorded under paragraph (h)(3)(ii) of this section in which the seal mechanism is broken, the bypass line valve position has changed, or the key to unlock the bypass line valve was checked out.

                                (b) Each owner or operator subject to the provisions of this subpart shall keep an up-to-date, readily accessible record of the following data measured during each performance test, and also include the following data in the report of the initial performance test required under § 60.8. Where a boiler or process heater with a design heat input capacity of 44 MW (150 million Btu/hour) or greater is used or where the reactor process vent stream is introduced as the primary fuel to any size boiler or process heater to comply with § 60.702(a), a report containing performance test data need not be submitted, but a report containing the information in paragraph (b)(2)(i) of this section is required. The same data specified in this section shall be submitted in the reports of all subsequently required performance tests where either the emission control efficiency of a combustion device, outlet concentration of TOC, or the TRE index value of a vent stream from a recovery system is determined. Beginning on July 15, 2024, owners and operators must submit the performance test report following the procedures specified in paragraph (u) of this section. Data collected using test methods that are supported by the EPA's Electronic Reporting Tool (ERT) as listed on the EPA's ERT website (
                                <E T="03">https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert</E>
                                ) at the time of the test must be submitted in a file format generated using the EPA's ERT. Alternatively, the owner or operator may submit an electronic file consistent with the extensible markup language (XML) schema listed on the EPA's ERT website. Data collected using test methods that are not supported by the EPA's ERT as listed on the EPA's ERT website at the time of the test must be included as an attachment in the ERT or an alternate electronic file.

                                (l) Each owner or operator that seeks to comply with the requirements of this subpart by complying with the requirements of § 60.700(c)(2), (3), or (4) or § 60.702 shall submit to the Administrator semiannual reports of the following recorded information. The initial report shall be submitted within 6 months after the initial start-up date. On and after July 15, 2025 or once the report template for this subpart has been available on the Compliance and Emissions Data Reporting Interface (CEDRI) website (
                                <E T="03">https://www.epa.gov/electronic-reporting-air-emissions/cedri</E>
                                ) for 1 year, whichever date is later, owners and operators must submit all subsequent reports using the appropriate electronic report template on the CEDRI website for this subpart and following the procedure specified in paragraph (u) of this section. The date report templates become available will be listed on the CEDRI website. Unless the Administrator or delegated state agency or other authority has approved a different schedule for submission of reports, the report must be submitted by the deadline specified in this subpart, regardless of the method in which the report is submitted.
                            </P>
                            <P>(1) Exceedances of monitored parameters recorded under paragraphs (c), (f), and (g) of this section.</P>
                            <P>(2) All periods and duration recorded under paragraph (d) of this section when the vent stream is diverted from the control device to the atmosphere.</P>

                                (4) Any change in equipment or process operation that increases the operating vent stream flow rate above the low flow exemption level in § 60.700(c)(4), including a measurement of the new vent stream flow rate, as recorded under paragraph (i) of this section. These must be reported as soon as possible after the change and no later than 180 days after the change. These reports may be submitted either in conjunction with semiannual reports or as a single separate report. A performance test must be completed within the same time period to verify the recalculated flow value and to obtain the vent stream characteristics of heating value and E

                                . The performance test is subject to the requirements of § 60.8, and the performance test must be reported according to paragraph (b) of this section. Unless the facility qualifies for an exemption under any of the exemption provisions listed in § 60.700(c), except for the total resource effectiveness index greater than 8.0 exemption in § 60.700(c)(2), the facility must begin compliance with the requirements set forth in § 60.702.
                            </P>
                            <P>
                                (5) Any change in equipment or process operation, as recorded under paragraph (i) of this section, that increases the design production capacity above the low capacity exemption level in § 60.700(c)(3) and the new capacity resulting from the change for the reactor process unit containing the affected facility. These must be reported as soon as possible after the change and no later than 180 days after the change. These reports may be submitted either in conjunction with semiannual reports or as a single separate report. A performance test must be completed within the same time period to obtain the vent stream flow rate, heating value, and E
                                <E T="52">TOC</E>
                                . The performance test is subject to the requirements of § 60.8, and the performance test must be reported according to paragraph (b) of this section. The facility must begin compliance with the requirements set forth in § 60.702 or § 60.700(d). If the facility chooses to comply with § 60.702, the facility may qualify for an exemption under § 60.700(c)(2), (4), or (8).

                            <P>(6) Any recalculation of the TRE index value, as recorded under paragraph (g) of this section.</P>
                            <P>(7) All periods recorded under paragraph (d) of this section in which the seal mechanism is broken or the by-pass line valve position has changed. A record of the serial number of the car-seal or a record to show that the key to unlock the bypass line valve was checked out must be maintained to demonstrate the period, the duration, and frequency in which the bypass line was operated.</P>
                            <P>(8) Any change in equipment or process operation that increases the vent stream concentration above the low concentration exemption level in § 60.700(c)(8), including a measurement of the new vent stream concentration, as recorded under paragraph (j) of this section. These must be reported as soon as possible after the change and no later than 180 days after the change. These reports may be submitted either in conjunction with semiannual reports or as a single separate report. If the vent stream concentration is above 300 ppmv as measured using Method 18 of appendix A-6 to this part, or ASTM D6420-18 (incorporated by reference, see § 60.17) as specified in § 60.704(b)(4), or above 150 ppmv as measured using Method 25A of appendix A-7 to this part, a performance test must be completed within the same time period to obtain the vent stream flow rate, heating value, and ETOC. The performance test is subject to the requirements of § 60.8, and the performance test must be reported according to paragraph (b) of this section. Unless the facility qualifies for an exemption under any of the exemption provisions listed in § 60.700(c), except for the TRE index greater than 8.0 exemption in § 60.700(c)(2), the facility must begin compliance with the requirements set forth in § 60.702.</P>
                            <P>
                                (m) The requirements of paragraph (l) of this section remain in force until and unless EPA, in delegating enforcement authority to a State under section 111(c) 
                                <PRTPAGE P="43131"/>
                                of the Act, approves reporting requirements or an alternative means of compliance surveillance adopted by such State. In that event, affected sources within the State will be relieved of the obligation to comply with paragraph (l), provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.
                            </P>
                            <STARS/>
                            <P>
                                (u) If an owner or operator is required to submit notifications or reports following the procedure specified in this paragraph (u), the owner or operator must submit notifications or 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 the owner or operator. Do not use CEDRI to submit information the owner or operator claims as CBI. Although the EPA does not expect persons to assert a claim of CBI, if an owner or operator wishes to assert a CBI claim for some of the information in the report or notification, the owner or operator must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (u)(1) and (2) of this section. Clearly mark the part or all of the information claimed 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. The owner or operator must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (u).
                            </P>
                            <P>
                                (1) The preferred method to receive CBI is for it to be transmitted electronically using email attachments, File Transfer Protocol, or other online file sharing services. Electronic submissions must be transmitted directly to the OAQPS CBI Office at the email address 
                                <E T="03">oaqpscbi@epa.gov,</E>
                                 and as described above, should include clear CBI markings. ERT files should be flagged to the attention of the Group Leader, Measurement Policy Group; all other files should be flagged to the attention of the SOCMI NSPS Sector Lead. Owners and operators who do not have their own file sharing service and who require assistance with submitting large electronic files that exceed the file size limit for email attachments should email 
                                <E T="03">oaqpscbi@epa.gov</E>
                                 to request a file transfer link.
                            </P>
                            <P>(2) If an owner or operator cannot transmit the file electronically, the owner or operator may send CBI information through the postal service to the following address: OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research Triangle Park, North Carolina 27711. ERT files should be sent to the attention of the Group Leader, Measurement Policy Group, and all other files should be sent to the attention of the SOCMI NSPS Sector Lead. The mailed CBI material should be double wrapped and clearly marked. Any CBI markings should not show through the outer envelope.</P>
                            <P>(v) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of EPA system outage for failure to timely comply with the electronic submittal requirement. To assert a claim of EPA system outage, owners and operators must meet the requirements outlined in paragraphs (v)(1) through (7) of this section.</P>
                            <P>(1) The owner or operator must have been or will be precluded from accessing CEDRI and submitting a required report within the time prescribed due to an outage of either the EPA's CEDRI or CDX systems.</P>

                            <P>(5) The owner or operator must provide to the Administrator a written description identifying:</P>
                            <P>(i) The date(s) and time(s) when CDX or CEDRI was accessed and the system was unavailable;</P>
                            <P>(ii) A rationale for attributing the delay in reporting beyond the regulatory deadline to EPA system outage;</P>
                            <P>(iii) A description of measures taken or to be taken to minimize the delay in reporting; and</P>
                            <P>(iv) The date by which the owner or operator proposes to report, or if the owner or operator has already met the reporting requirement at the time of the notification, the date the report was submitted.</P>
                            <P>(6) The decision to accept the claim of EPA system outage and allow an extension to the reporting deadline is solely within the discretion of the Administrator.</P>
                            <P>(7) In any circumstance, the report must be submitted electronically as soon as possible after the outage is resolved.</P>
                            <P>
                                (w) Owners and operators required to electronically submit notifications or reports through CEDRI in the EPA's CDX may assert a claim of

Any vent stream designated as a maintenance vent is only subject to the maintenance vent provisions in this paragraph (c) and the associated recordkeeping and reporting requirements in § 60.705a(g), respectively.</P>
                            <P>(1) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements of § 60.709a, as applicable, or using any combination of a non-flare control device or recovery device meeting the requirements in table 1 to this subpart until one of the following conditions, as applicable, is met.</P>
                            <P>(i) The vapor in the equipment served by the maintenance vent has a lower explosive limit (LEL) of less than 10 percent.</P>
                            <P>(ii) If there is no ability to measure the LEL of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the LEL of the vapors in the maintenance vent (or inside the equipment if the maintenance is a hatch or similar type of opening) is less than 10 percent.</P>
                            <P>
                                (iii) The equipment served by the maintenance vent contains less than 50 pounds of total VOC.

During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.</P>
                            <P>(2) Except for maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine the LEL or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.</P>
                            <P>(3) For maintenance vents complying with the alternative in paragraph (c)(1)(iii) of this section, you must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.</P>

                            <P>(1) Install a continuous parameter monitoring system(s) (CPMS) and monitor the operating parameter(s) applicable to the control device or recovery system as specified in table 2 to this subpart or established according to paragraph (c) of this section.</P>
                            <P>(2) Establish the applicable minimum, maximum, or range for the operating parameter limit as specified in Table 3 to this subpart or established according to paragraph (c) of this section by calculating the value(s) as the arithmetic average of operating parameter measurements recorded during the three test runs conducted for the most recent performance test. You may operate outside of the established operating parameter limit(s) during subsequent performance tests in order to establish new operating limits. You must include the updated operating limits with the performance test results submitted to the Administrator pursuant to § 60.705a(b). Upon establishment of a new operating limit, you must thereafter operate under the new operating limit. If the Administrator determines that you did not conduct the performance test in accordance with the applicable requirements or that the operating limit established during the performance test does not correspond to the conditions specified in § 60.704a(a), then you must conduct a new performance test and establish a new operating limit.</P>
                            <P>(3) Monitor, record, and demonstrate continuous compliance using the minimum frequencies specified in Table 3 to this subpart or established according to paragraph (c) of this section.</P>

                            <P>(i) Conduct an initial performance test or design evaluation of the adsorber and establish the breakthrough limit and adsorber bed life.</P>
                            <P>(ii) Monitor the TOC concentration through a sample port at the outlet of the first adsorber bed in series according to the schedule in paragraph (a)(6)(iii)(B) of this section. You must measure the concentration of TOC using either a portable analyzer, in accordance with Method 21 of appendix A-7 of this part using methane, propane, or isobutylene as the calibration gas or Method 25A of appendix A-7 of this part using methane or propane as the calibration gas.</P>
                            <P>(iii) Comply with paragraph (a)(6)(iii)(A) of this section and comply with the monitoring frequency according to paragraph (a)(6)(iii)(B) of this section.</P>

The original second adsorber (or a fresh canister) will become the new first adsorber and a fresh adsorber will become the second adsorber. For purposes of this paragraph (a)(6)(iii)(A), “immediately” means within 8 hours of the detection of a breakthrough for adsorbers of 55 gallons or less, and within 24 hours of the detection of a breakthrough for adsorbers greater than 55 gallons. You must monitor at the outlet of the first adsorber within 3 days of replacement to confirm it is performing properly.</P>
                            <P>(B) Based on the adsorber bed life established according to paragraph (a)(6)(i) of this section and the date the adsorbent was last replaced, conduct monitoring to detect breakthrough at least monthly if the adsorbent has more than 2 months of life remaining, at least weekly if the adsorbent has between 2 months and 2 weeks of life remaining, and at least daily if the adsorbent has 2 weeks or less of life remaining.</P>
                            <P>(7) If you install a continuous emissions monitoring system (CEMS) to demonstrate compliance with the TOC standard in Table 1 of this subpart, you must comply with the requirements specified in § 60.704a(g) in lieu of the requirements specified in paragraphs (a)(1) through (4) and (c) of this section.</P>
                            <P>(b) If you vent emissions through a closed vent system to a boiler or process heater, then the vent stream must be introduced into the flame zone of the boiler or process heater.</P>
                            <P>(c) If you seek to demonstrate compliance with the standards specified under § 60.702a with control devices other than an incinerator, boiler, process heater, or flare; or recovery devices other than an absorber, condenser, or carbon adsorber, you shall provide to the Administrator prior to conducting the initial performance test information describing the operation of the control device or recovery device and the parameter(s) which would indicate proper operation and maintenance of the device and how the parameter(s) are indicative of control of TOC emissions. The Administrator may request further information and will specify appropriate monitoring procedures or requirements, including operating parameters to be monitored, averaging times for determining compliance with the operating parameter limits, and ongoing calibration and quality control requirements.</P>

                                <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 CBI. Although we do not expect persons to assert a claim of CBI, if you wish to assert a CBI claim for some of the information in the report or notification, you must submit a complete file in the format specified in this subpart, including information claimed to be CBI, to the EPA following the procedures in paragraphs (l)(1) and (2) of this section. 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. All CBI claims must be asserted at the time of submission. Anything submitted using CEDRI cannot later be claimed CBI. Furthermore, under CAA section 114(c), emissions data is not entitled to confidential treatment, and the 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. You must submit the same file submitted to the CBI office with the CBI omitted to the EPA via the EPA's CDX as described earlier in this paragraph (l).

                                (5) In any circumstance, the reporting must occur as soon as possible after the 
                                <E T="03">force majeure</E>
                                 event occurs.
                            </P>
                            <P>(o) The requirements of paragraph (k) of this section remain in force until and unless EPA, in delegating enforcement authority to a State under section 111(c) of the Act, approves reporting requirements or an alternative means of compliance surveillance adopted by such State. In that event, affected sources within the State will be relieved of the obligation to comply with paragraph (k) of this section, provided that they comply with the requirements established by the State. The EPA will not approve a waiver of electronic reporting to the EPA in delegating enforcement authority. Thus, electronic reporting to the EPA cannot be waived, and as such, the provisions of this paragraph cannot be used to relieve owners or operators of affected facilities of the requirement to submit the electronic reports required in this section to the EPA.</P>
                            <P>(p) If you seek to demonstrate compliance with § 60.700a(c)(2), then you must submit to the Administrator an initial report detailing the design production capacity of the process unit.</P>
                            <P>(q) If you seek to demonstrate compliance with § 60.700a(c)(3), then you must submit to the Administrator an initial report including a flow rate measurement using the test methods specified in § 60.704a.</P>
                            <P>(r) If you seek to demonstrate compliance with § 60.700a(c)(4), then you must submit to the Administrator a process design description as part of the initial report. This process design description must be retained for the life of the process. No other records or reports would be required unless process changes are made.</P>
                            <P>(s) If you seek to demonstrate compliance with § 60.700a(c)(7), then you must submit to the Administrator an initial report including a concentration measurement using the test method specified in § 60.704a.</P>
                            <P>(t) The Administrator will specify appropriate reporting and recordkeeping requirements where the owner or operator of an affected facility complies with the standards specified under § 60.702a other than as provided under § 60.703a.</P>
                            <P>(u) If you seek to demonstrate compliance with § 60.702a using a control device, then you must maintain on file a schematic diagram of the affected vent streams, collection system(s), fuel systems, control devices, and bypass systems as part of the initial report. This schematic diagram must be retained for the life of the system.</P>
                            <P>(v) Any records required to be maintained by this subpart that are submitted electronically via the EPA's CEDRI may be maintained in electronic format. This ability to maintain electronic copies does not affect the requirement for facilities to make records, data, and reports available upon request to a delegated air agency or the EPA as part of an on-site compliance evaluation.</P>

                            <P>For purposes of this subpart “fixed capital cost of the new components,” as used in § 60.15, includes the fixed capital cost of all depreciable components which are or will be replaced pursuant to all continuous programs of component replacement which are commenced within any 2-year period following April 25, 2023. For purposes of this paragraph, “commenced” means that you have undertaken a continuous program of component replacement or that you have entered into a contractual obligation to undertake and complete, within a reasonable time, a continuous program of component replacement.</P>

                            <SECTNO>§ 60.709a</SECTNO>
                            <SUBJECT>What are my requirements if I use a flare to comply with this subpart?</SUBJECT>
                            <P>(a) If you use a flare to comply with the TOC emission standard specified in table 1 to this subpart, then you must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671 of this chapter, including the provisions in tables 12 and 13 to part 63, subpart CC, of this chapter, except as specified in paragraphs (b) through (o) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from an affected facility, as determined on an annual average basis. For purposes of compliance with this paragraph (a), the following terms are defined in § 63.641 of this chapter: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.</P>
                            <P>(b) When determining compliance with the pilot flame requirements specified in § 63.670(b) and (g) of this chapter, substitute “pilot flame or flare flame” for each occurrence of “pilot flame.”</P>
                            <P>(c) When determining compliance with the flare tip velocity and combustion zone operating limits specified in § 63.670(d) and (e) of this chapter, the requirement effectively applies starting with the 15-minute block that includes a full 15 minutes of the flaring event. You are required to demonstrate compliance with the velocity and NHVcz requirements starting with the block that contains the fifteenth minute of a flaring event. You are not required to demonstrate compliance for the previous 15-minute block in which the event started and contained only a fraction of flow.</P>
                            <P>(d) Instead of complying with § 63.670(o)(2)(i) of this chapter, you must develop and implement the flare management plan no later than startup for a new flare that commenced construction on or after April 25, 2023.</P>
                            <P>(e) Instead of complying with § 63.670(o)(2)(iii) of this chapter, if required to develop a flare management plan and submit it to the Administrator, then you must also submit all versions of the plan in portable document format (PDF) following the procedures specified in § 60.705a(l).</P>
                            <P>(f) Section 63.670(o)(3)(ii) of this chapter and all references to it do not apply. Instead, you must comply with the maximum flare tip velocity operating limit at all times.</P>
                            <P>(g) Substitute “affected facility” for each occurrence of “petroleum refinery.”</P>
                            <P>(h) Each occurrence of “refinery” does not apply.</P>
                            <P>(i) If a pressure-assisted multi-point flare is used as a control device, then you must meet the following conditions:</P>
                            <P>(1) You are not required to comply with the flare tip velocity requirements in § 63.670(d) and (k) of this chapter;</P>
                            <P>(2) The NHVcz for pressure-assisted mulit-point flares is 800 Btu/scf;</P>
                            <P>(3) You must determine the 15-minute block average NHVvg using only the direct calculation method specified in § 63.670(l)(5)(ii) of this chapter;</P>
                            <P>(4) Instead of complying with § 63.670(b) and (g) of this chapter, if a pressure-assisted multi-point flare uses cross-lighting on a stage of burners rather than having an individual pilot flame on each burner, then you must operate each stage of the pressure-assisted multi-point flare with a flame present at all times when regulated material is routed to that stage of burners. Each stage of burners that cross-lights in the pressure-assisted multi-point flare must have at least two pilots with at least one continuously lit and capable of igniting all regulated material that is routed to that stage of burners. Each 15-minute block during which there is at least one minute where no pilot flame is present on a stage of burners when regulated material is routed to the flare is a deviation of the standard. Deviations in different 15-minute blocks from the same event are considered separate deviations. The pilot flame(s) on each stage of burners that use cross-lighting must be continuously monitored by a thermocouple or any other equivalent device used to detect the presence of a flame;</P>
                            <P>
                                (5) Unless you choose to conduct a cross-light performance demonstration as specified in this paragraph (i)(5), you must ensure that if a stage of burners on the flare uses cross-lighting, that the distance between any two burners in series on that stage is no more than 6 feet when measured from the center of one burner to the next burner. A distance greater than 6 feet between any two burners in series may be used 
                                <PRTPAGE P="43145"/>
                                provided you conduct a performance demonstration that confirms the pressure-assisted multi-point flare will cross-light a minimum of three burners and the spacing between the burners and location of the pilot flame must be representative of the projected installation. The compliance demonstration must be approved by the permitting authority and a copy of this approval must be maintained onsite. The compliance demonstration report must include: a protocol describing the test methodology used, associated test method QA/QC parameters, the waste gas composition and NHVcz of the gas tested, the velocity of the waste gas tested, the pressure-assisted multi-point flare burner tip pressure, the time, length, and duration of the test, records of whether a successful cross-light was observed over all of the burners and the length of time it took for the burners to cross-light, records of maintaining a stable flame after a successful cross-light and the duration for which this was observed, records of any smoking events during the cross-light, waste gas temperature, meteorological conditions (
                                <E T="03">e.g.,</E>
                                 ambient temperature, barometric pressure, wind speed and direction, and relative humidity), and whether there were any observed flare flameouts; and
                            </P>
                            <P>(6) You must install and operate pressure monitor(s) on the main flare header, as well as a valve position indicator monitoring system for each staging valve to ensure that the flare operates within the proper range of conditions as specified by the manufacturer. The pressure monitor must meet the requirements in Table 13 to part 63, subpart CC of this chapter.</P>
                            <P>(7) If a pressure-assisted multi-point flare is operating under the requirements of an approved alternative means of emission limitations, you must either continue to comply with the terms of the alternative means of emission limitations or comply with the provisions in paragraphs (i)(1) through (6) of this section.</P>
                            <P>(j) If you choose to determine compositional analysis for net heating value with a continuous process mass spectrometer, then you must comply with the requirements specified in paragraphs (j)(1) through (7) of this section.</P>
                            <P>(1) You must meet the requirements in § 63.671(e)(2) of this chapter. You may augment the minimum list of calibration gas components found in § 63.671(e)(2) of this chapter with compounds found during a pre-survey or known to be in the gas through process knowledge.</P>
                            <P>(2) Calibration gas cylinders must be certified to an accuracy of 2 percent and traceable to National Institute of Standards and Technology (NIST) standards.</P>
                            <P>(3) For unknown gas components that have similar analytical mass fragments to calibration compounds, you may report the unknowns as an increase in the overlapped calibration gas compound. For unknown compounds that produce mass fragments that do not overlap calibration compounds, you may use the response factor for the nearest molecular weight hydrocarbon in the calibration mix to quantify the unknown component's NHVvg.</P>
                            <P>(4) You may use the response factor for n-pentane to quantify any unknown components detected with a higher molecular weight than n-pentane.</P>
                            <P>(5) You must perform an initial calibration to identify mass fragment overlap and response factors for the target compounds.</P>
                            <P>(6) You must meet applicable requirements in Performance Specification 9 of appendix B of this part, for continuous monitoring system acceptance including, but not limited to, performing an initial multi-point calibration check at three concentrations following the procedure in section 10.1 and performing the periodic calibration requirements listed for gas chromatographs in table 13 to part 63, subpart CC, of this chapter, for the process mass spectrometer. You may use the alternative sampling line temperature allowed under Net Heating Value by Gas Chromatograph in table 13 to part 63, subpart CC, of this chapter.</P>
                            <P>(7) The average instrument calibration error (CE) for each calibration compound at any calibration concentration must not differ by more than 10 percent from the certified cylinder gas value. The CE for each component in the calibration blend must be calculated using Equation 1 to this paragraph (j)(7).</P>

                            <SUBJECT>What are my requirements for closed vent systems?</SUBJECT>
                            <P>(a) Except as provided in paragraphs (f) and (g) of this section, you must inspect each closed vent system according to the procedures and schedule specified in paragraphs (a)(1) through (3) of this section.</P>
                            <P>(1) Conduct an initial inspection according to the procedures in paragraph (b) of this section unless the closed vent system is operated and maintained under negative pressure,</P>
                            <P>(2) Conduct annual inspections according to the procedures in paragraph (b) of this section unless the closed vent system is operated and maintained under negative pressure, and</P>
                            <P>(3) Conduct annual inspections for visible, audible, or olfactory indications of leaks.</P>
                            <P>(b) You must inspect each closed vent system according to the procedures specified in paragraphs (b)(1) through (6) of this section.</P>
                            <P>(1) Inspections must be conducted in accordance with Method 21 of appendix A of this part.</P>
                            <P>(2)(i) Except as provided in paragraph (b)(2)(ii) of this section, the detection instrument must meet the performance criteria of Method 21 of appendix A of this part, except the instrument response factor criteria in section 3.1.2(a) of Method 21 must be for the average composition of the process fluid not each individual volatile organic compound in the stream. For process streams that contain nitrogen, air, or other inerts which are not organic hazardous air pollutants or volatile organic compounds, the average stream response factor must be calculated on an inert-free basis.</P>
                            <P>(ii) If no instrument is available at the plant site that will meet the performance criteria specified in paragraph (b)(2)(i) of this section, the instrument readings may be adjusted by multiplying by the average response factor of the process fluid, calculated on an inert-free basis as described in paragraph (b)(2)(i) of this section.</P>
                            <P>(3) The detection instrument must be calibrated before use on each day of its use by the procedures specified in Method 21 of appendix A of this part.</P>
                            <P>(4) Calibration gases must be as follows:</P>
                            <P>(i) Zero air (less than 10 parts per million hydrocarbon in air); and</P>
                            <P>(ii) Mixtures of methane in air at a concentration less than 2,000 parts per million. A calibration gas other than methane in air may be used if the instrument does not respond to methane or if the instrument does not meet the performance criteria specified in paragraph (b)(2)(i) of this section. In such cases, the calibration gas may be a mixture of one or more of the compounds to be measured in air.</P>
                            <P>(5) You may elect to adjust or not adjust instrument readings for background. If you elect to not adjust readings for background, all such instrument readings must be compared directly to the applicable leak definition to determine whether there is a leak.</P>
                            <P>(6) If you elect to adjust instrument readings for background, you must determine the background concentration using Method 21 of appendix A of this part. After monitoring each potential leak interface, subtract the background reading from the maximum concentration indicated by the instrument. The arithmetic difference between the maximum concentration indicated by the instrument and the background level must be compared with 500 parts per million for determining compliance.</P>
                            <P>(c) Leaks, as indicated by an instrument reading greater than 500 parts per million above background or by visual, audio, or olfactory inspections, must be repaired as soon as practicable, except as provided in paragraph (d) of this section.</P>
                            <P>(1) A first attempt at repair must be made no later than 5 calendar days after the leak is detected.</P>
                            <P>(2) Repair must be completed no later than 15 calendar days after the leak is detected.</P>
                            <P>(d) Delay of repair of a closed vent system for which leaks have been detected is allowed if the repair is technically infeasible without a shutdown, as defined in § 60.2, or if you determine that emissions resulting from immediate repair would be greater than the fugitive emissions likely to result from delay of repair. Repair of such equipment must be complete by the end of the next shutdown.</P>
                            <P>(e) For each closed vent system that contains bypass lines that could divert a vent stream away from the control device and to the atmosphere, you must comply with the provisions of either paragraph (e)(1) or (2), except as specified in paragraph (e)(3) of this section.</P>
                            <P>(1) Install, calibrate, maintain, and operate a flow indicator that determines whether vent stream flow is present at least once every 15 minutes. You must keep hourly records of whether the flow indicator was operating and whether a diversion was detected at any time during the hour, as well as records of the times and durations of all periods when the vent stream is diverted to the atmosphere or the flow indicator is not operating. The flow indicator must be installed at the entrance to any bypass line; or</P>
                            <P>(2) Secure the bypass line valve in the closed position with a car-seal or a lock-and-key type configuration. A visual inspection of the seal or closure mechanism must be performed at least once every month to ensure the valve is maintained in the closed position and the vent stream is not diverted through the bypass line.</P>
                            <P>
                                (3) Open-ended valves or lines that use a cap, blind flange, plug, or second valve and follow the requirements specified in § 60.482-6(a)(2), (b), and (c) or follow requirements codified in another regulation that are the same as 
                                <PRTPAGE P="43148"/>
                                § 60.482-6(a)(2), (b), and (c) are not subject to this paragraph (e) of this section.
                            </P>
                            <P>(f) Any parts of the closed vent system that are designated, as described in paragraph (h)(1) of this section, as unsafe to inspect are exempt from the inspection requirements of paragraphs (a)(1) and (2) of this section if:</P>
                            <P>(1) You determine that the equipment is unsafe to inspect because inspecting personnel would be exposed to an imminent or potential danger as a consequence of complying with paragraphs (a)(1) and (2) of this section; and</P>
                            <P>(2) You have a written plan that requires inspection of the equipment as frequently as practicable during safe-to-inspect times.</P>
                            <P>(g) Any parts of the closed vent system are designated, as described in paragraph (h)(2) of this section, as difficult to inspect are exempt from the inspection requirements of paragraphs (a)(1) and (2) of this section if:</P>
                            <P>(1) You determine that the equipment cannot be inspected without elevating the inspecting personnel more than 2 meters above a support surface; and</P>
                            <P>(2) You have a written plan that requires inspection of the equipment at least once every 5 years.</P>
                            <P>(h) You must record the information specified in paragraphs (h)(1) through (5) of this section.</P>
                            <P>(1) Identification of all parts of the closed vent system that are designated as unsafe to inspect, an explanation of why the equipment is unsafe to inspect, and the plan for inspecting the equipment.</P>
                            <P>(2) Identification of all parts of the closed vent system that are designated as difficult to inspect, an explanation of why the equipment is difficult to inspect, and the plan for inspecting the equipment.</P>
                            <P>(3) For each closed vent system that contains bypass lines that could divert a vent stream away from the control device and to the atmosphere, you must keep a record of the information specified in either paragraph (h)(3)(i) or (ii) of this section in addition to the information specified in paragraph (h)(3)(iii) of this section.</P>
                            <P>(i) Hourly records of whether the flow indicator specified under paragraph (e)(1) of this section was operating and whether a diversion was detected at any time during the hour, as well as records of the times of all periods when the vent stream is diverted from the control device or the flow indicator is not operating.</P>
                            <P>(ii) Where a seal mechanism is used to comply with paragraph (e)(2) of this section, hourly records of flow are not required. In such cases, you must record whether the monthly visual inspection of the seals or closure mechanisms has been done, and you must record the occurrence of all periods when the seal mechanism is broken, the bypass line valve position has changed, or the key for a lock-and-key type configuration has been checked out, and records of any car-seal that has broken.</P>
                            <P>(iii) For each flow event from a bypass line subject to the requirements in paragraph (e) of this section, you must maintain records sufficient to determine whether or not the detected flow included flow requiring control. For each flow event from a bypass line requiring control that is released either directly to the atmosphere or to a control device not meeting the requirements in this subpart, you must include an estimate of the volume of gas, the concentration of VOC in the gas and the resulting emissions of VOC that bypassed the control device using process knowledge and engineering estimates.</P>
                            <P>(4) For each inspection during which a leak is detected, a record of the information specified in paragraphs (h)(4)(i) through (viii) of this section.</P>
                            <P>(i) The instrument identification numbers; operator name or initials; and identification of the equipment.</P>
                            <P>(ii) The date the leak was detected and the date of the first attempt to repair the leak.</P>
                            <P>(iii) Maximum instrument reading measured by the method specified in paragraph (c) of this section after the leak is successfully repaired or determined to be nonrepairable.</P>
                            <P>(iv) “Repair delayed” and the reason for the delay if a leak is not repaired within 15 calendar days after discovery of the leak.</P>
                            <P>(v) The name, initials, or other form of identification of the owner or operator (or designee) whose decision it was that repair could not be effected without a shutdown.</P>
                            <P>(vi) The expected date of successful repair of the leak if a leak is not repaired within 15 calendar days.</P>
                            <P>(vii) Dates of shutdowns that occur while the equipment is unrepaired.</P>
                            <P>(viii) The date of successful repair of the leak.</P>

                            <P>(6) For each inspection conducted in accordance with paragraph (a)(3) of this section during which no leaks are detected, a record that the inspection was performed, the date of the inspection, and a statement that no leaks were detected.</P>
                            <P>(i) The semiannual report specified in § 60.705a(k)(5) must include the items specified in paragraphs (i)(1) through (3) of this section.</P>
                            <P>(1) Reports of the times of all periods recorded under paragraph (h)(3)(i) of this section when the vent stream is diverted from the control device through a bypass line. Include the start date, start time, and duration in hours of each period.</P>
                            <P>(2) Reports of all periods recorded under paragraph (h)(3)(ii) of this section in which the seal mechanism is broken, the bypass line valve position has changed, or the key to unlock the bypass line valve was checked out. Include the start date, start time, and duration in hours of each period.</P>

For purposes of this paragraph (q)(3), the term “excess emissions” means emissions in excess of those that would have occurred if the transferee had continued managing the gas stream in compliance with the requirements in §§ 63.113 through 63.118. The measures to be taken shall be identified in the applicable startup, shutdown, and malfunction plan. If the measures that can be reasonably taken will change over time, so that a more effective measure which could not reasonably be taken initially would be reasonable at a later date, the Administrator may require the more effective measure by a specified date (in addition to or instead of any other measures taken sooner or later than that date) as a condition of approval of the compliance schedule.

This paragraph does not apply if the item of equipment is malfunctioning, or if the owner or operator must shut down the equipment to avoid damage due to a contemporaneous start-up, shutdown, or malfunction of the chemical manufacturing process unit or portion thereof.</P>
                            <P>(4) During start-ups, shutdowns, and malfunctions when the requirements of this subpart and subparts G and/or H of this part do not apply pursuant to paragraphs (a)(1) through (3) of this section, the owner or operator shall implement, to the extent reasonably available, measures to prevent or minimize excess emissions to the extent practical. The general duty to minimize emissions during a period of startup, shutdown, or malfunction does not require the owner or operator to achieve emission levels that would be required by the applicable standard at other times if this is not consistent with safety and good air pollution control practices, nor does it require the owner or operator to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether such operation and maintenance procedures are being used will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures (including the startup, shutdown, and malfunction plan required in § 63.6(e)(3)), review of operation and maintenance records, and inspection of the source. The measures to be taken may include, but are not limited to, air pollution control technologies, recovery technologies, work practices, pollution prevention, monitoring, and/or changes in the manner of operation of the source. Back-up control devices are not required but may be used if available.</P>

                                (b) If, in the judgment of the Administrator, an alternative means of emission limitation will achieve a reduction in organic HAP emissions at least equivalent to the reduction in organic HAP emissions from that source achieved under any design, equipment, work practice, or operational standards in subpart G or H of this part, the Administrator will publish in the 
                                <E T="04">Federal Register</E>
                                 a notice permitting the use of the alternative means for purposes of compliance with that requirement.
                            </P>
                            <P>(1) The notice may condition the permission on requirements related to the operation and maintenance of the alternative means.</P>
                            <P>(2) Any notice under this paragraph (b) shall be published only after public notice and an opportunity for a hearing.</P>
                            <P>(3) Any person seeking permission to use an alternative means of compliance under this section shall collect, verify, and submit to the Administrator information showing that the alternative means achieves equivalent emission reductions.</P>
                            <P>(c) Each owner or operator of a source subject to this subpart shall obtain a permit under 40 CFR part 70 or part 71 from the appropriate permitting authority by the date determined by 40 CFR part 70 or part 71, as appropriate.</P>
                            <P>(1) If the EPA has approved a State operating permit program under 40 CFR part 70, the permit shall be obtained from the State authority. If the State operating permit program has not been approved, the source shall apply to the EPA Regional Office.</P>
                            <P>(2) [Reserved]</P>
                            <P>(d) The requirements in this subpart and subparts G and H of this part are federally enforceable under section 112 of the Act on and after the dates specified in § 63.100(k) of this subpart.</P>
                            <P>(e) For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), paragraph (a) of this section does not apply. Instead, owners and operators of sources as defined in § 63.101 shall comply with the requirements in this subpart and subparts G and H of this part at all times, except during periods of nonoperation of the source (or specific portion thereof) resulting in cessation of the emissions to which this subpart or subpart G or H of this part applies.</P>
                            <P>(f) For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), at all times, owners and operators must operate and maintain any source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require owners and operators to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether a source is operating in compliance with operation and maintenance requirements will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source.</P>

                            <P>(iv) Beginning no later than the compliance dates specified in § 63.100(k)(10), the manufacturer's specifications specified in paragraph (c)(2)(iii) of this section must include a schedule for calibrations, preventative maintenance procedures, a schedule for preventative maintenance, and corrective actions to be taken if a calibration fails. If a continuous monitoring system calibration fails, the continuous monitoring system is considered to be inoperative until the owner or operator takes corrective action and the system passes calibration. The owner or operator must record the nature and cause of instances when the continuous monitoring system is inoperative and the corrective action taken.</P>

                                (a) For any flare that is used to reduce organic HAP emissions from a chemical manufacturing process unit, the owner or operator may elect to comply with the requirements in this section in lieu of the requirements of § 63.11(b) and the requirements referenced therein. The owner or operator may also elect to comply with the requirements in this section pursuant to the overlap provisions provided in § 63.110(j). However, for each source as defined in

                                § 63.101 and for each source as defined in § 63.191, beginning no later than the compliance dates specified in § 63.100(k)(10), the provisions specified in paragraphs (a)(1) through (22) of this section no longer apply. Instead, if an owner or operator reduces organic HAP emissions from a chemical manufacturing process unit by venting emissions through a closed-vent system to a steam-assisted, air-assisted, non-assisted, or pressure-assisted multi-point flare, then the owner or operator must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671, including the provisions in tables 12 and 13 to subpart CC of this part, except as specified in paragraphs (b) through (o) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from a chemical manufacturing process unit, as determined on an annual average basis. For purposes of compliance with this paragraph, the following terms are defined in § 63.641: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.

                            <P>(c) When determining compliance with the flare tip velocity and combustion zone operating limits specified in § 63.670(d) and (e), the requirement effectively applies starting with the 15-minute block that includes a full 15 minutes of the flaring event. The owner or operator is required to demonstrate compliance with the velocity and NHVcz requirements starting with the block that contains the fifteenth minute of a flaring event. The owner or operator is not required to demonstrate compliance for the previous 15-minute block in which the event started and contained only a fraction of flow.</P>
                            <P>(d) Instead of complying with § 63.670(o)(2)(i), owners and operators must develop and implement the flare management plan no later than the compliance dates specified in § 63.100(k)(10).</P>
                            <P>(e) Instead of complying with § 63.670(o)(2)(iii), if required to develop a flare management plan and submit it to the Administrator, then owners and operators must also submit all versions of the plan in portable document format (PDF) to the EPA following the procedure specified in § 63.9(k), except any medium submitted through mail must be sent to the attention of the Hazardous Organic Chemical Manufacturing Sector Lead.</P>
                            <P>(f) Section 63.670(o)(3)(ii) and all references to it do not apply. Instead, the owner or operator must comply with the maximum flare tip velocity operating limit at all times.</P>
                            <P>(g) Substitute “chemical manufacturing process unit” for each occurrence of “petroleum refinery.”</P>
                            <P>(h) Each occurrence of “refinery” does not apply.</P>
                            <P>(i) If a pressure-assisted multi-point flare is used as a control device, then owners and operators must meet the following conditions:</P>
                            <P>(1) The owner or operator is not required to comply with the flare tip velocity requirements in § 63.670(d) and (k);</P>
                            <P>(2) The NHVcz for pressure-assisted mulit-point flares is 800 Btu/scf;</P>
                            <P>(3) Owners and operators must determine the 15-minute block average NHVvg using only the direct calculation method specified in § 63.670(l)(5)(ii);</P>
                            <P>(4) Instead of complying with § 63.670(b) and (g), if a pressure-assisted multi-point flare uses cross-lighting on a stage of burners rather than having an individual pilot flame on each burner, then owners and operators must operate each stage of the pressure-assisted multi-point flare with a flame present at all times when regulated material is routed to that stage of burners. Each stage of burners that cross-lights in the pressure-assisted multi-point flare must have at least two pilots with at least one continuously lit and capable of igniting all regulated material that is routed to that stage of burners. Each 15-minute block during which there is at least one minute where no pilot flame is present on a stage of burners when regulated material is routed to the flare is a violation of the standard. Violations in different 15-minute blocks from the same event are considered separate violations. The pilot flame(s) on each stage of burners that use cross-lighting must be continuously monitored by a thermocouple or any other equivalent device used to detect the presence of a flame;</P>
                            <P>
                                (5) Unless the owner or operator chooses to conduct a cross-light performance demonstration as specified in this paragraph, owners and operators must ensure that if a stage of burners on the flare uses cross-lighting, that the distance between any two burners in series on that stage is no more than 6 feet when measured from the center of one burner to the next burner. A distance greater than 6 feet between any two burners in series may be used provided the owner or operator conducts a performance demonstration that confirms the pressure-assisted multi-point flare will cross-light a minimum of three burners and the spacing between the burners and location of the pilot flame must be representative of the projected installation. The compliance demonstration must be approved by the permitting authority and a copy of this approval must be maintained onsite. The compliance demonstration report must include: a protocol describing the test methodology used, associated test method QA/QC parameters, the waste gas composition and NHVcz of the gas tested, the velocity of the waste gas tested, the pressure-assisted multi-point flare burner tip pressure, the time, length, and duration of the test, records of whether a successful cross-light was observed over all of the burners and the length of time it took for the burners to cross-light, records of maintaining a stable flame after a successful cross-light and the duration for which this was observed, records of any smoking events during the cross-light, waste gas temperature, meteorological conditions (

                            <P>
                                (6) Owners and operators must install and operate pressure monitor(s) on the 
                                <PRTPAGE P="43171"/>
                                main flare header, as well as a valve position indicator monitoring system for each staging valve to ensure that the flare operates within the proper range of conditions as specified by the manufacturer. The pressure monitor must meet the requirements in table 13 to subpart CC of this part.
                            </P>
                            <P>(7) If a pressure-assisted multi-point flare is operating under the requirements of an approved alternative means of emission limitations, owners and operators must either continue to comply with the terms of the alternative means of emission limitations or comply with the provisions in paragraphs (i)(1) through (6) of this section.</P>
                            <P>(j) If an owner or operator chooses to determine compositional analysis for net heating value with a continuous process mass spectrometer, then the owner or operator must comply with the requirements specified in paragraphs (j)(1) through (7) of this section.</P>
                            <P>(1) Owners and operators must meet the requirements in § 63.671(e)(2). The owner or operator may augment the minimum list of calibration gas components found in § 63.671(e)(2) with compounds found during a pre-survey or known to be in the gas through process knowledge.</P>
                            <P>(2) Calibration gas cylinders must be certified to an accuracy of 2 percent and traceable to National Institute of Standards and Technology (NIST) standards.</P>
                            <P>(3) For unknown gas components that have similar analytical mass fragments to calibration compounds, the owner or operator may report the unknowns as an increase in the overlapped calibration gas compound. For unknown compounds that produce mass fragments that do not overlap calibration compounds, the owner or operator may use the response factor for the nearest molecular weight hydrocarbon in the calibration mix to quantify the unknown component's NHVvg.</P>
                            <P>(4) The owner or operator may use the response factor for n-pentane to quantify any unknown components detected with a higher molecular weight than n-pentane.</P>
                            <P>(5) Owners and operators must perform an initial calibration to identify mass fragment overlap and response factors for the target compounds.</P>
                            <P>(6) Owners and operators must meet applicable requirements in Performance Specification 9 in appendix B to part 60 of this chapter for continuous monitoring system acceptance including, but not limited to, performing an initial multi-point calibration check at three concentrations following the procedure in section 10.1 and performing the periodic calibration requirements listed for gas chromatographs in table 13 to subpart CC of this part, for the process mass spectrometer. The owner or operator may use the alternative sampling line temperature allowed under Net Heating Value by Gas Chromatograph in table 13 to subpart CC of this part.</P>
                            <P>(7) The average instrument calibration error (CE) for each calibration compound at any calibration concentration must not differ by more than 10 percent from the certified cylinder gas value. The CE for each component in the calibration blend must be calculated using equation 1 to this paragraph.</P>

For a piece of equipment to be considered not in ethylene oxide service, it must be determined that the percent ethylene oxide content of the process fluid that is contained in or contacts equipment can be reasonably expected to not exceed 0.1 percent by weight on an annual average basis. For purposes of determining the percent ethylene oxide content of the process fluid, owners and operators must use Method 18 of appendix A-6 to part 60 of this chapter, for gaseous process fluid, and Method 624.1 of appendix A to part 136 of this chapter, or preparation by Method SW-846-5031 and analysis by Method SW-846-8260D (both incorporated by reference, see § 63.14) for liquid process fluid. In lieu of preparation by Method SW-846-5031, owners and operators may use Method SW-846-5030B (incorporated by reference, see § 63.14), as long as: the owner or operator does not use a

                            <P>(3) Owners and operators may revise a determination for whether a piece of equipment is in ethylene oxide service by following the procedures in paragraph (c)(1) of this section, or by documenting that a change in the process or raw materials no longer causes the equipment to be in ethylene oxide service.</P>
                            <P>(4) Samples used in determining the ethylene oxide content must be representative of the process fluid that is contained in or contacts the equipment.</P>
                            <P>(d) For wastewater, owners and operators must determine the concentration of ethylene oxide of each wastewater stream using Method 624.1 of appendix A to part 136 of this chapter, or preparation by either Method SW-846-5031 or SW-846-5030B and analysis by Method SW-846-8260D (incorporated by reference, see § 63.14). The owner or operator may not use a preservative in the collected sample; the owner or operator must store the sample with minimal headspace as cold as possible and at least below 4 degrees C; and the owner or operator must analyze the sample as soon as possible, but in no case longer than 7 days from the time the sample was collected.</P>

                            <P>(ii) Halogenated vent streams, as defined in § 63.111, shall not be vented to a flare.</P>
                            <P>(2) Reduce emissions of total organic hazardous air pollutants by 98 weight-percent or to a concentration of 20 parts per million by volume. For combustion devices, the emission reduction or concentration shall be calculated on a dry basis, corrected to 3-percent oxygen, and compliance can be determined by measuring either organic hazardous air pollutants or total organic carbon using the procedures in § 63.116.</P>
                            <P>(i) Compliance with paragraph (a)(2) of this section may be achieved by using any combination of combustion, recovery, and/or recapture devices, except that a recovery device may not be used to comply with paragraph (a)(2) of this section by reducing emissions of total organic hazardous air pollutants by 98 weight-percent, except as provided in paragraph (a)(2)(ii) of this section.</P>
                            <P>(ii) An owner or operator may use a recovery device, alone or in combination with one or more combustion or recapture devices, to reduce emissions of total organic hazardous air pollutants by 98 weight-percent if all the conditions of paragraphs (a)(2)(ii)(A) through (a)(2)(ii)(D) of this section are met.</P>
                            <P>(A) The recovery device (and any combustion device or recapture device which operates in combination with the recovery device to reduce emissions of total organic hazardous air pollutants by 98 weight-percent) was installed before the date of proposal of the subpart of this part 63 that makes this subpart G applicable to process vents in the chemical manufacturing process unit.</P>
                            <P>(B) The recovery device that will be used to reduce emissions of total organic hazardous air pollutants by 98 weight-percent is the last recovery device before emission to the atmosphere.</P>
                            <P>(C) The recovery device, alone or in combination with one or more combustion or recapture devices, is capable of reducing emissions of total organic hazardous air pollutants by 98 weight-percent, but is not capable of reliably reducing emissions of total organic hazardous air pollutants to a concentration of 20 parts per million by volume.</P>
                            <P>(D) If the owner or operator disposed of the recovered material, the recovery device would comply with the requirements of this subpart for recapture devices.</P>
                            <P>(3) Except as specified in paragraph (a)(4) of this section, achieve and maintain a TRE index value greater than 1.0 at the outlet of the final recovery device, or prior to release of the vent stream to the atmosphere if no recovery device is present. If the TRE index value is greater than 1.0, the process vent shall comply with the provisions for a Group 2 process vent specified in either paragraph (d) or (e) of this section, whichever is applicable.</P>
                            <P>(4) For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), the provisions specified in paragraphs (a)(4)(i) through (xv) of this section no longer apply.

                            <P>(k) For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), an owner or operator may designate a process vent as a maintenance vent if the vent is only used as a result of startup, shutdown, maintenance, or inspection of equipment where equipment is emptied, depressurized, degassed, or placed into service. The owner or operator must comply with the applicable requirements in paragraphs (k)(1) through (4) of this section for each maintenance vent. Any vent designated as a maintenance vent is only subject to the maintenance vent provisions in this paragraph (k) and the associated reporting and recordkeeping requirements in § 63.118(f)(9) and (m), respectively. The owner or operator does not need to designate a maintenance vent as a Group 1 or Group 2 process vent nor identify maintenance vents in a Notification of Compliance Status report.</P>
                            <P>(1) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements of § 63.108, as applicable, or using any combination of a non-flare combustion, recovery, and/or recapture device meeting the requirements in paragraph (a)(2) of this section until one of the following conditions, as applicable, is met.</P>
                            <P>(i) The concentration of the vapor in the equipment served by the maintenance vent is less than 10 percent of its lower explosive limit (LEL) and has an outlet concentration less than or equal to 20 ppmv hydrogen halide and halogen HAP.</P>
                            <P>(ii) If there is no ability to measure the concentration of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the concentration of the vapors in the maintenance vent (or inside the equipment if the maintenance is a hatch or similar type of opening) is less than 10 percent of its LEL.</P>
                            <P>(iii) The equipment served by the maintenance vent contains less than 50 pounds of total volatile organic compounds (VOC).</P>
                            <P>(iv) If, after applying best practices to isolate and purge equipment served by a maintenance vent, none of the applicable criterion in paragraphs (k)(1)(i) through (iii) of this section can be met prior to installing or removing a blind flange or similar equipment blind, then the pressure in the equipment served by the maintenance vent must be reduced to 2 psig or less before installing or removing the equipment blind. During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.</P>
                            <P>(2) Except for maintenance vents complying with the alternative in paragraph (k)(1)(iii) of this section, the owner or operator must determine the concentration or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.</P>
                            <P>(3) For maintenance vents complying with the alternative in paragraph (k)(1)(iii) of this section, the owner or operator must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.</P>
                            <P>(4) In addition to complying with the requirements in paragraphs (k)(1) through (3) of this section, for process vents in ethylene oxide service, subject to the requirements of § 63.124 that are designated as maintenance vents, owners and operators may not release more than 1.0 tons of ethylene oxide from all maintenance vents combined per any consecutive 12-month period. The owner or operator must keep monthly records of the quantity in tons of ethylene oxide released from each maintenance vent and include a description of the method used to estimate this quantity.</P>
                            <P>(l) For each source as defined in § 63.101, beginning no later than the compliance dates specified in § 63.100(k)(10), paragraphs (f) and (g) of this section no longer apply. Instead, the owner or operator of a Group 2 process vent with a total organic HAP mass flow rate less than 1.0 pound per hour shall maintain a total organic HAP mass flow rate less than 1.0 pound per hour; comply with the Group determination procedures in § 63.115(g); and the reporting and recordkeeping requirements in §§ 63.117(g) and 63.118(n); and is not subject to monitoring or any other provisions of §§ 63.114 through 63.118.</P>

                                 This paragraph provides instructions for determining whether a wastewater stream is Group 1 or Group 2 for Table 8 compounds. Annual average concentration for each Table 8 compound shall be determined according to the procedures specified in § 63.144(b). Annual average flow rate shall be determined according to the procedures specified in § 63.144(c).

                            <P>(2) A wastewater stream is a Group 2 wastewater stream for Table 8 compounds if it does not meet the criteria specified in paragraph (d)(1)(ii) of this section, and the annual average flow rate is less than 0.02 liter per minute or the annual average concentration for each individual Table 8 compound is less than 10 parts per million by weight.</P>
                            <P>(3) The owner or operator of a Group 2 wastewater shall re-determine group status for each Group 2 stream, as necessary, to determine whether the stream is Group 1 or Group 2 whenever process changes are made that could reasonably be expected to change the stream to a Group 1 stream. Examples of process changes include, but are not limited to, changes in production capacity, production rate, feedstock type, or whenever there is a replacement, removal, or addition of recovery or control equipment. For purposes of this paragraph (d)(3), process changes do not include: Process upsets; unintentional, temporary process changes; and changes that are within the range on which the original determination was based.</P>

                                (i) The monitoring system is capable of detecting unrealistic or impossible data during periods of operation other than startups, shutdowns, or malfunctions (
                                <E T="03">e.g.,</E>
                                 a temperature reading of −200 °C on a boiler), and will alert the operator by alarm or other means. The owner or operator shall record the occurrence. All instances of the alarm or other alert in an operating day constitute a single occurrence. For each source as defined in § 63.101, on and after July 15, 2027, the phrase “other than startups, shutdowns, or malfunctions (
                                <E T="03">e.g.,</E>
                                 a temperature reading of −200 °C on a boiler),” in this paragraph no longer applies.
                            </P>
                            <P>(ii) The monitoring system generates, updated at least hourly throughout each operating day, a running average of the monitoring values that have been obtained during that operating day, and the capability to observe this average is readily available to the Administrator on-site during the operating day. The owner or operator shall record the occurrence of any period meeting the criteria in paragraphs (g)(1)(ii)(A) through (C) of this section. All instances in an operating day constitute a single occurrence.</P>
                            <P>(A) The running average is above the maximum or below the minimum established limits;</P>
                            <P>(B) The running average is based on at least 6 1-hour average values; and</P>
                            <P>(C) The running average reflects a period of operation other than a startup, shutdown, or malfunction. For each source as defined in § 63.101, on and after July 15, 2027, the phrase “other than a startup, shutdown, or malfunction” in this paragraph no longer applies.</P>
                            <P>
                                (iii) The monitoring system is capable of detecting unchanging data during periods of operation other than startups, shutdowns, or malfunctions, except in circumstances where the presence of unchanging data is the expected operating condition based on past experience (
                                <E T="03">e.g.,</E>
                                 pH in some scrubbers), and will alert the operator by alarm or other means. The owner or operator shall record the occurrence. All instances of the alarm or other alert in an operating day constitute a single occurrence. For each source as defined in § 63.101, on and after July 15, 2027, the phrase “other than startups, shutdowns, or malfunctions” in this paragraph no longer applies.
                            </P>
                            <P>(iv) The monitoring system will alert the owner or operator by an alarm or other means, if the running average parameter value calculated under paragraph (g)(1)(ii) of this section reaches a set point that is appropriately related to the established limit for the parameter that is being monitored.</P>
                            <P>(v) The owner or operator shall verify the proper functioning of the monitoring system, including its ability to comply with the requirements of paragraph (g)(1) of this section, at the times specified in paragraphs (g)(1)(v)(A) through (C) of this section. The owner or operator shall document that the required verifications occurred.</P>
                            <P>(A) Upon initial installation.</P>
                            <P>(B) Annually after initial installation.</P>
                            <P>(C) After any change to the programming or equipment constituting the monitoring system, which might reasonably be expected to alter the monitoring system's ability to comply with the requirements of this section.</P>
                            <P>(vi) The owner or operator shall retain the records identified in paragraphs (g)(1)(vi)(A) through (C) of this section.</P>
                            <P>(A) Identification of each parameter, for each item of equipment, for which the owner or operator has elected to comply with the requirements of paragraph (g) of this section.</P>

                                storage; log entries) for each required record. If the description changes, the owner or operator shall retain both the current and the most recent superseded description. The description, and the most recent superseded description, shall be retained as provided in § 63.103(c) of subpart F of this part, except as provided in paragraph (g)(1)(vi)(D) of this section.
                            </P>
                            <P>(C) A description, and the date, of any change to the monitoring system that would reasonably be expected to affect its ability to comply with the requirements of paragraph (g)(1) of this section.</P>
                            <P>(D) Owners and operators subject to paragraph (g)(1)(vi)(B) of this section shall retain the current description of the monitoring system as long as the description is current, but not less than 5 years from the date of its creation. The current description shall, at all times, be retained on-site or be accessible from a central location by computer or other means that provides access within 2 hours after a request. The owner or operator shall retain the most recent superseded description at least until 5 years from the date of its creation. The superseded description shall be retained on-site (or accessible from a central location by computer that provides access within 2 hours after a request) at least 6 months after its creation. Thereafter, the superseded description may be stored off-site.</P>
                            <P>(2) If an owner or operator has elected to implement the requirements of paragraph (g)(1) of this section, and a period of 6 consecutive months has passed without an excursion as defined in paragraph (g)(2)(iv) of this section, the owner or operator is no longer required to record the daily average value for that parameter for that unit of equipment, for any operating day when the daily average value is less than the maximum, or greater than the minimum established limit. With approval by the Administrator, monitoring data generated prior to the compliance date of this subpart shall be credited toward the period of 6 consecutive months, if the parameter limit and the monitoring was required and/or approved by the Administrator.</P>
                            <P>(i) If the owner or operator elects not to retain the daily average values, the owner or operator shall notify the Administrator in the next periodic report. The notification shall identify the parameter and unit of equipment.</P>
                            <P>(ii) If, on any operating day after the owner or operator has ceased recording daily averages as provided in paragraph (g)(2) of this section, there is an excursion as defined in paragraph (g)(2)(iv) of this section, the owner or operator shall immediately resume retaining the daily average value for each day, and shall notify the Administrator in the next periodic report. The owner or operator shall continue to retain each daily average value until another period of 6 consecutive months has passed without an excursion as defined in paragraph (g)(2)(iv) of this section.</P>
                            <P>(iii) The owner or operator shall retain the records specified in paragraphs (g)(1) (i), (ii), (iii), (iv), (v), and (vi) of this section. For any calendar week, if compliance with paragraphs (g)(1) (i), (ii), (iii), and (iv) of this section does not result in retention of a record of at least one occurrence or measured parameter value, the owner or operator shall record and retain at least one parameter value during a period of operation other than a startup, shutdown, or malfunction. For each source as defined in § 63.101, on and after July 15, 2027, the phrase “other than a startup, shutdown, or malfunction” in this paragraph no longer applies.</P>
                            <P>(iv) For purposes of paragraph (g) of this section, an excursion means that the daily average value of monitoring data for a parameter is greater than the maximum, or less than the minimum established value, except as provided in paragraphs (g)(2)(iv)(A) and (B) of this section.</P>
                            <P>(A) The daily average value during any startup, shutdown, or malfunction shall not be considered an excursion for purposes of this paragraph (g)(2), if the owner or operator operates the source during such periods in accordance with § 63.102(a)(4). For each source as defined in § 63.101, on and after July 15, 2027, this paragraph no longer applies.</P>
                            <P>(B) An excused excursion, as described in § 63.152(c)(2)(ii)(B) and (C), shall not be considered an excursion for purposes of this paragraph (g)(2).</P>
                            <P>
                                (h) Beginning no later than July 15, 2024, owners and operators must submit performance test reports in accordance with this paragraph. Unless otherwise specified in this subpart, within 60 days after the date of completing each performance test required by this subpart, owners and operators must submit the results of the performance test following the procedures specified in § 63.9(k).

When calculating Δc for the monitoring period when using this alternative for burden reduction, use zero for the lowest sampling result for each monitoring period where one or more samples was not taken and/or analyzed for the analyte(s) that qualifies for this alternative sampling frequency. This alternative for burden reduction is determined on an analyte specific basis. If an owner or operator is not required to sample for a particular analyte for a particular monitoring site in accordance with this paragraph (a)(3)(iii), the owner or operator must still sample for any other analytes required by paragraph (a)(1) of this section at the frequency specified in paragraph (a)(3)(ii) of this section, unless the other analyte(s) also qualifies for this alternative for burden reduction.

                                 on an annual average basis.
                            </P>
                            <P>(e) Once any action level in paragraph (d)(3) of this section has been exceeded, the owner or operator must take the following actions to bring the annual average Δc back below the action level(s).</P>
                            <P>
                                (1) Within 5 days of updating the annual average value as required in paragraph (d)(2) of this section and determining that any action level in paragraph (d)(3) of this section has been exceeded (
                                <E T="03">i.e.,</E>
                                 in no case longer than 50 days after completion of the sampling period), the owner or operator must initiate a root cause analysis to determine appropriate corrective action. A root cause analysis is an assessment conducted through a process of investigation to determine the primary underlying cause and all other contributing causes to an exceedance of an action level(s) set forth in paragraph (d)(3) of this section.
                            </P>
                            <P>(i) The initial root cause analysis may include, but is not limited to:</P>
                            <P>(A) Leak inspection using Method 21 of appendix A-7 to 40 CFR part 60, optical gas imaging, or handheld monitors.</P>
                            <P>(B) Visual inspection to determine the cause of the high emissions.</P>
                            <P>
                                (C) Operator knowledge of process changes (
                                <E T="03">e.g.,</E>
                                 a malfunction or release event).
                            </P>
                            <P>(ii) If the initial root cause cannot be identified using the type of techniques described in paragraph (e)(1)(i) of this section, the owner or operator must employ more frequent sampling and analysis to determine the root cause of the exceedance.</P>
                            <P>(A) The owner or operator may first employ additional monitoring points and shorter sampling periods for Methods 325A and 325B of appendix A to this part for benzene, 1,3-butadiene, chloroprene, or ethylene dichloride or more frequent sampling with Method 327 of appendix A to this part for ethylene oxide or vinyl chloride to determine the root cause of the exceedance.</P>
                            <P>
                                (B) If the owner or operator has not determined the root cause of the exceedance within 30 days of determining that the action level has been exceeded, the owner or operator must employ the appropriate real-time sampling techniques (
                                <E T="03">e.g.,</E>
                                 mobile gas chromatographs, optical spectroscopy instruments, sensors) to locate the cause of the exceedance. If the root cause is not identified after 48 hours, either the real-time monitor must be relocated or an additional real-time monitor must be added. Relocation or addition of extra real-time monitors must continue after each 48-hour period of nonidentification until the owner or operator can identify the root cause of the exceedance.
                            </P>
                            <P>(2) If the underlying primary and other contributing causes of the exceedance are deemed to be under the control of the owner or operator, the owner or operator must take appropriate corrective action as expeditiously as possible to bring annual average fenceline concentrations back below the action level(s) set forth in paragraph (d)(3) of this section. At a minimum, the corrective actions taken must address the underlying primary and other contributing cause(s) determined in the root cause analysis to prevent future exceedances from the same underlying cause(s).</P>
                            <P>(3) The root cause analysis must be completed and initial corrective actions taken no later than 45 days after determining there is an exceedance of an action level.</P>
                            <P>(4) Until the annual average Δc is below the action level again, following completion of the initial corrective action, the owner or operator must conduct a new root cause analysis according to this paragraph (e), and if required, submit a corrective action plan under paragraph (f) of this section following any sampling period for which the sampling start time begins after the completion of the initial corrective actions and for which the Δc for the sampling period is greater than the level specified in paragraphs (e)(4)(i) through (vi) of this section for the compound(s) that initially exceeded the action level.</P>

The corrective action plan must describe the corrective action(s) completed to date, additional measures that the owner or operator proposes to employ to reduce annual average fenceline concentrations below the action level(s) set forth in paragraph (d)(3) of this section, and a schedule for completion of these measures. The corrective action plan does not need to be approved by the Administrator. However, if upon review, the Administrator disagrees with the additional measures outlined in the plan, the owner or operator must revise and resubmit the plan within 7 calendar days of receiving comments from the Administrator.</P>

                            <P>(h) The owner or operator must comply with the applicable recordkeeping and reporting requirements in §§ 63.181 and 63.182.</P>
                            <P>(i) As outlined in § 63.7(f), the owner or operator may submit a request for an alternative test method. At a minimum, the request must follow the requirements outlined in paragraphs (i)(1) through (7) of this section.</P>
                            <P>(1) The alternative method may be used in lieu of all or a partial number of passive samplers required in Method 325A of appendix A to this part or the canister sampling locations required under paragraph (b) of this section.</P>

                            <P>(3) The method detection limit must nominally be at least one-third of the action level for the compound(s) that will be monitored with the alternative method. The alternate test method must describe the procedures used to provide field verification of the detection limit.</P>
                            <P>(4) If the alternative test method will be used to replace some or all passive samplers required under paragraph (a) of this section, the spatial coverage must be equal to or better than the spatial coverage provided in Method 325A of appendix A to this part. If the alternative test method will be used to replace some or all canisters required under paragraph (b) of this section, the spatial coverage must be equal to or better than the spatial coverage provided under paragraph (b) of this section.</P>
                            <P>(i) For path average concentration open-path instruments, the physical path length of the measurement must be no more than a passive sample footprint (the spacing that would be provided by the sorbent traps when following Method 325A of appendix A to this part) or canister sample footprint, as applicable. For example, if Method 325A requires spacing monitors A and B 610 meters (2,000 feet) apart, then the physical path length limit for the measurement at that portion of the fenceline must be no more than 610 meters (2,000 feet).</P>
                            <P>(ii) For range resolved open-path instrument or approach, the instrument or approach must be able to resolve an average concentration over each passive sampler footprint or canister sample footprint within the path length of the instrument.</P>
                            <P>(iii) The extra samplers required in Sections 8.2.1.3 of Method 325A of appendix A to this part may be omitted when they fall within the path length of an open-path instrument.</P>
                            <P>(5) At a minimum, non-integrating alternative test methods must provide a minimum of one cycle of operation (sampling, analyzing, and data recording) for each successive 15-minute period.</P>
                            <P>(6) For alternative test methods capable of real time measurements (less than a 5 minute sampling and analysis cycle), the alternative test method may allow for elimination of data points corresponding to outside emission sources for purpose of calculation of the high point for the two week average. The alternative test method approach must have wind speed, direction and stability class of the same time resolution and within the footprint of the instrument.</P>
                            <P>(7) For purposes of averaging data points to determine the Δc for the individual sampling period, all results measured under the method detection limit must use the method detection limit. For purposes of averaging data points for the individual sampling period low sample result, all results measured under the method detection limit must use zero.</P>

The owner or operator does not need to designate a maintenance vent as a Group 1 or Group 2 batch front-end process vent nor identify maintenance vents in a Notification of Compliance Status report.</P>
                            <P>(1) Prior to venting to the atmosphere, remove process liquids from the equipment as much as practical and depressurize the equipment to either: A flare meeting the requirements of § 63.508, as applicable, or using any combination of a non-flare combustion, recovery, and/or recapture device meeting the requirements in paragraph (a)(2) of this section until one of the following conditions, as applicable, is met.</P>
                            <P>(i) The concentration of the vapor in the equipment served by the maintenance vent is less than 10 percent of its lower explosive limit (LEL) and has an outlet concentration less than or equal to 20 ppmv hydrogen halide and halogen HAP.</P>
                            <P>(ii) If there is no ability to measure the concentration of the vapor in the equipment based on the design of the equipment, the pressure in the equipment served by the maintenance vent is reduced to 5 pounds per square inch gauge (psig) or less. Upon opening the maintenance vent, active purging of the equipment cannot be used until the concentration of the vapors in the maintenance vent (or inside the equipment if the maintenance is a hatch or similar type of opening) is less than 10 percent of its LEL.</P>
                            <P>(iii) The equipment served by the maintenance vent contains less than 50 pounds of total volatile organic compounds (VOC).</P>
                            <P>(iv) If, after applying best practices to isolate and purge equipment served by a maintenance vent, none of the applicable criterion in paragraphs (i)(1)(i) through (i)(1)(iii) of this section can be met prior to installing or removing a blind flange or similar equipment blind, then the pressure in the equipment served by the maintenance vent must be reduced to 2 psig or less before installing or removing the equipment blind. During installation or removal of the equipment blind, active purging of the equipment may be used provided the equipment pressure at the location where purge gas is introduced remains at 2 psig or less.</P>
                            <P>(2) Except for maintenance vents complying with the alternative in paragraph (i)(1)(iii) of this section, the owner or operator must determine the concentration or, if applicable, equipment pressure using process instrumentation or portable measurement devices and follow procedures for calibration and maintenance according to manufacturer's specifications.</P>
                            <P>(3) For maintenance vents complying with the alternative in paragraph (i)(1)(iii) of this section, the owner or operator must determine mass of VOC in the equipment served by the maintenance vent based on the equipment size and contents after considering any contents drained or purged from the equipment. Equipment size may be determined from equipment design specifications. Equipment contents may be determined using process knowledge.</P>
                            <P>
                                (4) In addition to complying with the requirements in paragraphs (i)(1) through (i)(3) of this section, for batch front-end process vents that are in chloroprene service and subject to the requirements of § 63.510 that are designated as maintenance vents, owners and operators may not release more than 1.0 tons of chloroprene from all maintenance vents combined (

                            <P>(a) For any flare that is used to reduce organic HAP emissions from an EPPU, the owner or operator may elect to comply with the requirements in this section in lieu of the requirements of § 63.11(b) and the requirements referenced therein. The owner or operator may also elect to comply with the requirements in this section pursuant to the overlap provisions provided in § 63.481(k)(2). However, beginning no later than the compliance dates specified in § 63.481(n), the provisions specified in paragraphs (a)(1) through (32) of this section no longer apply. Instead, if an owner or operator reduces organic HAP emissions from an EPPU by venting emissions through a closed-vent system to a steam-assisted, air-assisted, or non-assisted flare, then the owner or operator must meet the applicable requirements for flares as specified in §§ 63.670 and 63.671, including the provisions in tables 12 and 13 to subpart CC of this part, except as specified in paragraph (b) of this section. This requirement also applies to any flare using fuel gas from a fuel gas system, of which 50 percent or more of the fuel gas is derived from a EPPU, as determined on an annual average basis. For purposes of compliance with this paragraph, the following terms are defined in § 63.641 of subpart CC of this part: Assist air, assist steam, center steam, combustion zone, combustion zone gas, flare, flare purge gas, flare supplemental gas, flare sweep gas, flare vent gas, lower steam, net heating value, perimeter assist air, pilot gas, premix assist air, total steam, and upper steam.</P>

                            <P>(a) The owner or operator of any existing affected BLR source shall, in order to demonstrate compliance with the applicable emission limits, determine the emission rate from all process vent, storage tank, and wastewater system emission points using the methods described below. Except as specified in paragraph (l) of this section, compliance tests shall be performed under normal operating conditions. Beginning no later than the compliance dates specified in § 63.521(c), conduct subsequent performance tests no later than 60 calendar months after the previous performance test.</P>
                            <P>(1) Except as specified in paragraph (m) of this section, the owner or operator shall use the EPA test methods from 40 CFR part 60, listed in paragraphs (a)(1) (i) through (iii) of this section, to determine emissions from process vents. Testing of process vents on equipment operating as part of a continuous process will consist of conducting three 1-hour runs. Gas stream volumetric flow rates shall be measured every 15 minutes during each 1-hour run. Organic HAP or TOC concentration shall be determined from samples collected in an integrated sample over the duration of each 1-hour test run, or from grab samples collected simultaneously with the flow rate measurements (every 15 minutes). If an integrated sample is collected for laboratory analysis, the sampling rate shall be adjusted proportionally to reflect variations in flow rate. If the flow of gaseous emissions is intermittent, determination of emissions from process vents shall be performed according to the methods specified in paragraph (e) of this section. For process vents with continuous gas streams, the emission rate used to determine compliance shall be the average emission rate of the 3 test runs. For process vents with intermittent emission streams, the calculated emission rate or the emission rate from a single test run may be used to determine compliance.</P>
                            <P>(i) Method 1 or 1A of appendix A-1 to 40 CFR part 60 as appropriate, shall be used for selection of the sampling sites if the flow measuring device is a pitot tube. A traverse shall be conducted before and after each 1-hour sampling period. No traverse is necessary when using Method 2A or 2D of appendix A-2 to 40 CFR part 60 to determine flow rate.</P>
                            <P>(ii) Method 2, 2A, 2C or 2D of appendix A-1 to part 60 of this chapter, as appropriate, shall be used for the determination of gas stream volumetric flow rate. If Method 2 or 2C is used, the velocity measurements shall be made at a single point, in conjunction with the traverse, to establish an average velocity across the stack.</P>
                            <P>(iii) Method 25A and/or Methods 18 and 25A of appendices A-6 and A-7 to 40 CFR part 60, as appropriate, must be used to determine the concentration of HAP in the streams. ASTM D6420-18 (incorporated by reference, see § 63.14) may also be used in lieu of Method 18, if the target compounds are all known and are all listed in Section 1.1 of ASTM D6420-18 as measurable; ASTM D6420-18 must not be used for methane and ethane; and ASTM D6420-18 may not be used as a total VOC method.</P>

                            <P>(j) For each existing, new, or reconstructed affected BLR and WSR source, beginning no later than the compliance dates specified in § 63.521(c), owners and operators of sources as defined in § 63.520 shall comply with the requirements of this subpart at all times, except during periods of nonoperation of the source (or specific portion thereof) resulting in cessation of the emissions to which this subpart applies.</P>
                            <P>(k) For each existing, new, or reconstructed affected BLR and WSR source, beginning no later than the compliance dates specified in § 63.521(c), at all times, owners and operators must operate and maintain any source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require owners and operators to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether a source is operating in compliance with operation and maintenance requirements will be based on information available to the Administrator which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source.</P>
                            <P>(l) For each existing, new, or reconstructed affected BLR and WSR source, beginning no later than the compliance dates specified in § 63.521(c), the owner or operator may not conduct performance tests during periods of malfunction. Owners and operators must record the process information that is necessary to document operating conditions during the test and include in such record an explanation to support that such conditions represent normal operation. Upon request, owners and operators must make available to the Administrator such records as may be necessary to determine the conditions of performance tests.</P>

During each compliance demonstration, maximum or minimum operating parameters, as appropriate, shall be established for processes and control devices that will indicate the source is in compliance. If the operating parameter to be established is a maximum, the value of the parameter shall be the average of the maximum values from each of the three test runs. If the operating parameter to be established is a minimum, the value of the parameter shall be the average of the minimum values from each of the three test runs. Parameter values for process vents with intermittent emission streams shall be determined as specified in paragraph (b)(1) of this section. The owner or operator shall operate processes and control devices within these parameters to ensure continued compliance with the standard. A de minimis level is specified in paragraph (a)(1) of this section. Monitoring parameters are specified for various process vent control scenarios in paragraphs (a) (2) through (7) of this section.</P>

                        <HD SOURCE="HD1">1.0 Scope and Application</HD>
                        <P>1.1 This method describes the sampling and analysis of emissions from fugitive and area sources collected using specially prepared canisters and analyzed using a gas chromatograph (GC) coupled with a low- or high-resolution mass spectrometer (MS) for the determination of the airborne concentration of selected volatile organic hazardous air pollutants (oHAPs) such as ethylene oxide or vinyl chloride.</P>
                        <P>
                            1.2 Applicability. The use of this method is strictly intended for determining airborne concentrations of selected speciated oHAPs to determine compliance with a fenceline emission standard and/or work practices when specified by the applicable regulation. This method includes data quality objectives (DQOs) specific to the measurement of airborne concentrations of speciated oHAPs and must not be used for other compliance purposes (
                            <E T="03">i.e.,</E>
                             measurements from ducted sources).
                        </P>
                        <P>1.3 The analytical approach for this method uses a GC coupled with a low- or high-resolution MS, which may consist of a linear quadrupole, ion trap, or time-of-flight (TOF) system. Speciated oHAPs are identified by a combination of the retention times (RTs) and the associated mass spectra by comparing observed fragmentation patterns to reference spectral patterns and relative ion abundances established during calibration. For the speciated oHAPs, the intensity of the observed quantitation ion in the unknown sample is compared with the system response to the same ion for known amounts of the compound.</P>
                        <P>1.4 The sampling and analytical approach included in this method is based on previously published EPA guidance in Compendium Method TO-15A, which describes the sampling and analytical procedures for measuring volatile organic compounds (VOCs) in ambient air.</P>
                        <HD SOURCE="HD1">2.0 Summary of Method</HD>
                        <P>
                            2.1 In this method, a whole air sample is collected through a particulate filter with a flow control device into an evacuated, specially prepared canister for a length of time specified by the applicable regulation, typically 24 hours. After the air sample is collected, the canister valve is closed, the canister pressure is measured, and the canister is transported to the laboratory for analysis. Upon receipt at the laboratory, the sample collection information is verified, the canister pressure is measured, and the canister is stored at ambient laboratory temperature until analysis. For analysis, a known volume of the sample is directed from the canister into a preconcentrator to collect speciated oHAPs from the sample aliquot and to allow the majority of bulk gases (
                            <E T="03">e.g.,</E>

                        <P>
                            2.2 The laboratory, field laboratory, and field personnel must have experience with sampling trace-level oHAPs using specially prepared canisters and with operating preconcentrator/GC/multidetector instrumentation (
                            <E T="03">e.g.,</E>
                             MS) for trace-level analysis.
                        </P>
                        <P>2.3 This method is performance-based and includes a description of the equipment, instruments, operations, and acceptance and performance criteria. EPA developed these criteria to ensure the collection of high-quality data. Laboratories must develop their own standard operating procedure (SOP) documents describing the equipment, equipment management, targeted compounds, procedures, and quality assurance (QA) activities specific to that laboratory, instrumentation, and potentially specific for the targeted analyte.</P>
                        <P>2.4 The key steps of this method required for the collection of each sample include stringent leak testing under stop flow, using certified and clean canisters, using certified sampling devices, collecting accurate field data, and collecting field blanks and duplicates. The key steps of this method required for sample analysis include the analysis of blanks, use of high-quality reference standards, and initial and ongoing calibration checks of the instruments used.</P>

                            4.1 Sample Collection. There are potential physical interferents which could impact the ability to properly time-integrate the sampling, such as leaks of the sampling system or introduction of foreign material (

                             particulate matter [PM], insect nests, spider webs). These interferences are mitigated by closely following the sampling protocols included in this method (

                             leak check procedures and sampling system requirements).

                        <P>4.2 Canister Sampling Media Interferences. Each canister will have its own specific performance characteristics and appropriate cleaning, sampling, and handling procedures are required for attainment of acceptable initial and ongoing method performance. Failure to adhere to the cleaning and certification requirements included in this method may lead to the following interference issues:</P>
                        <P>
                            (1) Incomplete deactivation of canister interior surfaces (
                            <E T="03">e.g.,</E>
                             canister welds) may result in active sites for adsorption or surfaces that facilitate the decomposition of labile VOCs to form other VOCs within the canister. Other potential sources of active sites include canister valves, valve stems, and ferrules. Damage to the canister interior that exposes untreated surfaces may also result in active sites.
                        </P>
                        <P>(2) Entrained PM deposited in the canister sampling pathway can adsorb VOCs making them unavailable in the canister gas phase which interferes with collected samples. Such trapped VOCs can potentially desorb later and result in the inability to achieve canister cleanliness performance specifications and/or contaminate subsequent canister sampling events. Additionally, organic PM can react with co-sampled ozone or other oxidative species to form target VOCs. PM can also clog tiny openings in critical or restrictive orifices, which impacts collection flow rates.</P>
                        <P>
                            (3) Under certain conditions, the composition of an air sample may change upon its introduction into the canister and over time such that the air in the canister no longer represents the air sampled. Such changes may be caused by interactions of the VOCs with the interior canister surface or between chemicals in the air matrix. The activity of the interior canister surface is unique to each canister and is based on several factors, including variability in canister manufacturing defects, differences in 
                            <PRTPAGE P="43278"/>
                            canister surface deactivation treatments, the presence of PM and co-collected moisture in the canister, and artifacts from reactions of VOCs on the canister walls.
                        </P>
                        <P>(4) Condensed water within the canister can result in corrosion of the interior surface of canisters with weak or deficient coatings and can result in the partitioning of hydrophilic polar VOCs to liquid water. Under such circumstances, concentrations of these analytes in the gas phase will be biased low until the condensation is eliminated by reduction of the canister pressure below the vapor saturation pressure of water.</P>
                        <P>4.3 Analytical Interferences. Contamination within the analytical system may come from several sources including, but not limited to, off-gassing of materials within the sample introduction or preconcentrator flow path, carryover from high-concentration samples or standards, and solvent vapors within the laboratory.</P>
                        <P>(1) Active sites within the sample introduction or preconcentration flow path are often caused by use of improper materials or degradation of deactivated surfaces.</P>
                        <P>(2) Impurities in source materials or diluent gases for internal standard (IS) gas mixtures may result in contamination of target VOCs.</P>
                        <P>(3) Water and the delivery systems used to humidify canisters or diluent gas streams may contaminate the canister contents or humidified gases.</P>
                        <P>(4) Moisture in the sample gas may interfere with VOC analysis by GC-MS. Poor or inconsistent water management during preconcentration can cause peak broadening and RT shifts that can result in peak misidentification, particularly for hydrophilic polar compounds. Water management systems that use semipermeable fluoropolymer membranes remove oxygenated and polar VOCs from the sample matrix and exhibit memory effects for several VOCs. VOCs entrained in the fluoropolymer membrane can convert to ketones and alcohols, which are transported across the membrane bidirectionally such that these ketones and alcohols can contaminate the sample stream and VOCs in the sample stream can be adsorbed into the fluoropolymer and removed from the sample stream.</P>
                        <P>(5) Carbon dioxide in the collected sample can coelute with more volatile VOCs eluting early in the GC-MS run and interfere with their quantitation.</P>
                        <P>(6) Artifacts in chromatograms, such as silanol compounds formed from the breakdown of silicon-ceramic linings of canisters and siloxane compounds from the breakdown of the stationary phase in an analytical column, can interfere with identification and quantitation of less volatile VOCs.</P>
                        <P>
                            (7) Be cognizant of compounds that interfere with target analytes when operating in MS modes that do not provide full-scan ion spectra (
                            <E T="03">i.e.,</E>
                             selected ion monitoring [SIM] and selected ion storage [SIS]). Such interfering coeluting compounds may share common ions, may have similar mass spectra, and may be difficult or impossible to separate from target VOCs.

                                Specially prepared canisters are commercially available with a modest range of options for surface preparation of the canister interior surfaces, valves, and connections. Currently, canister interior surfaces are typically passivated by electropolishing or coating with a silicon-ceramic film. EPA does not require a specific treatment or design and any canister type may be used for this method contingent on meeting the performance criteria in this section; however, silicon-ceramic coated canisters have demonstrated superior performance when used to sample reactive compounds, (

                        </NOTE>
                        <P>8.3.1.2 Canisters should be handled with care to ensure that the interior canister surface is not compromised, the valve-to-canister connection remains intact, and weld integrity is maintained. Excessive torque on unbraced canister valve stems when making connections may cause damage and potentially leaks in the valve stem weld or at the ferrule sealing the canister valve and canister stem. Shocks resulting in dents to the surface of the canister may damage welds or create small cracks in the interior canister surface that may expose active sites.

                        <P>9.1.1 Prepare a humidified SSCV standard in a canister at a concentration in the lower third of the calibration curve. The SSCV standard must contain all compounds in the calibration mixture. The SSCV standard must be prepared independently from the calibration standards using a certified secondary source calibration standard.</P>
                        <P>9.1.2 Analyze the SSCV after the initial calibration (ICAL). Recovery of each target oHAP in the SSCV standard must be within ±30% of the theoretical concentration.</P>
                        <P>9.2 Continuing Calibration Verification (CCV) Standard. Prepare a humidified CCV standard as a dilution of a certified standard in a canister at a concentration in the lower third of the calibration curve. This certified standard must be prepared from the same standard used for the ICAL standards.</P>
                        <P>9.2.1 Analyze a CCV for each target oHAP prior to analyzing samples, after every 10 sample injections, and at the end of the analytical sequence. Prepare a humidified CCV standard as a dilution of a certified standard in a canister at a concentration in the lower third of the calibration curve. This certified standard must be prepared from the cylinder used for the ICAL standards.</P>
                        <P>9.2.2 The internal standard (IS) area responses for each CCV standard must meet the criteria outlined in Section 10.8.1.5 of this method, and the quantitated concentrations of the target compounds for each CCV standard must be within ±30% of the theoretical concentrations as determined using Equation 4 in Section 12 of this method.</P>
                        <P>9.2.3 If the CCV is not within specifications, you must invalidate any results after the last successful CCV. You must investigate and address CCV failures and initiate corrective actions, including, for example, reanalyzing the CCV, preparing and analyzing a new CCV or standard canister, and performing a new ICAL.</P>
                        <P>9.3 Blank Analyses. Analysis of all blanks must demonstrate each target compound is &lt;20 pptv 14.7 psia or undetected (whichever is more stringent) per compound of interest.

The MB consists of a canister filled with humidified (40 to 50% RH) clean diluent gas and is analyzed via the same instrument method as the standards and field samples in the analytical sequence. Your MB must be the same diluent used for sample dilution.</P>
                        <P>9.3.3 Canister Field Blank. Analyze the canister field blank as part of the same analytical sequence as the accompanying field samples.</P>
                        <P>9.3.4 Calibration Blank (CB). Analyze the CB when the ICAL is established and when preparing any new CCV standard using the same instrument method that was used for standards and field samples when establishing the ICAL. The CB consists of a canister filled with the humidified (40 to 50% RH) clean diluent gas sourced through the dilution system employed to prepare standards. For laboratories that do not employ a dynamic or automated static dilution system, the CB consists of a humidified (40 to 50% RH) canister of the gas used to dilute the calibration standard.</P>
                        <P>9.4 Duplicate samples must be analyzed and reported as part of this method. They are used to evaluate sampling and/or analytical precision.</P>
                        <P>9.4.1 Field Duplicate. The level of agreement between duplicate field samples is a measure of the precision achievable for the entire sampling and analysis. Analyze the field duplicate during the same analytical sequence as the accompanying field sample. The RPD of the precision measurements should agree within ±30% when both measurements are ≥5 times the MDL. Flag associated results to indicate if the RPD indicates poor method precision.</P>
                        <P>9.4.2 Replicate Analysis. The level of agreement between replicate samples is a measure of precision achievable for the analysis. Analyze at least one replicate analysis for each set of field-collected samples. The RPD of the precision measurements should agree within ±25% when both measurements are ≥5 times the MDL.

                        <P>10.1.1 Calculate the volume of water you must add to standard and blank canisters to achieve 40 to 50% RH at ambient laboratory temperature. (See Equation 6 in Section 12 of this method).</P>
                        <P>10.1.2 Use a bubbler or impinger within the dilution gas stream, add water to the canister, or use a combination of these two methods to add the calculated volume of deionized water to the canister necessary to achieve internal RH of approximately 40 to 50% at ambient laboratory temperature. For direct injection of water into a canister with a syringe, install a high-pressure PTFE-sealed septum on the canister. For canisters that are to be connected to a gas source for pressurization via a dynamic or static dilution system, you can add the deionized water to the valve opening of the evacuated canister prior to connecting to the dilution system. Do not add water to the canister using a syringe via rubber septum or other materials that may introduce target or interfering compounds.</P>

                        <P>10.2.1 Gas Dilution System. The gas dilution system must produce calibration gases whose measured concentration values are within ±2% of the predicted values. The predicted values are calculated based on the certified concentration of the supply gas (Protocol gases, when available, are recommended for their accuracy) and the gas flow rates (or dilution ratios) through the gas dilution system.</P>

                        <P>10.2.3.1 Prior to use, power on the dynamic dilution system and allow the diluent and stock gases to flow through the respective MFC at operating flow rates. Allow gases to flow for at least the minimum time used during the yearly bias check in Section 6.10.1.3 of this method, to ensure the concentrations of the oHAPs in the blended gas are stable prior to transferring to the humidified canister (or directly to the preconcentrator).</P>
                        <P>10.2.3.2 You must prepare humidified (40 to 50% RH) standards in canisters from low concentration to high concentration. When changing stock gas flow rate(s) to prepare a different concentration, allow the calibration gas sufficient time to flow through the system prior to preparation of the working calibration canister (or delivering the working standard directly to the preconcentrator).</P>
                        <P>10.2.3.3 The final pressure of the calibration standard canister must not exceed the maximum pressure permitted by the preconcentrator.</P>

                    <FP>By the authority vested in me as President by the Constitution and the laws of the United States of America, including section 721 of the Defense Production Act of 1950, as amended (section 721), 50 U.S.C. 4565, it is hereby ordered as follows:</FP>
                    <FP>
                        <E T="04">Section 1</E>
                        . 
                        <E T="03">Findings.</E>
                         I hereby make the following findings:
                    </FP>
                    <P>(a) There is credible evidence that leads me to believe that (1) MineOne Partners Limited, a British Virgin Islands company ultimately majority owned by Chinese nationals (“MineOne Partners”); (2) MineOne Cloud Computing Investment I L.P., a British Virgin Islands limited partnership (“MineOne Cloud”); (3) MineOne Data Center LLC, a Delaware limited liability company (“MineOne Data”); and (4) MineOne Wyoming Data Center LLC, a Delaware limited liability company (“MineOne Wyoming” and together with MineOne Partners, MineOne Cloud, MineOne Data, and MineOne Wyoming, the “Purchasers”), through the acquisition of certain real estate that is located within 1 mile of Francis E. Warren Air Force Base (“Warren AFB”) (specifically, the 12.06 acres described as Lot 1, Block 10 North Range Business Park 3rd Filing, located at 635 Logistics Drive, Cheyenne, Wyoming, 82009) (the “Real Estate” and such acquisition the “Transaction”), might take action that threatens to impair the national security of the United States;</P>
                    <P>(b) MineOne acquired the Real Estate in June 2022 and then made improvements to allow for use of the Real Estate for specialized cryptocurrency mining operations in close proximity to Warren AFB, a strategic missile base and home to Minuteman III intercontinental ballistic missiles;</P>
                    <P>(c) The Transaction was not filed with the Committee on Foreign Investment in the United States (CFIUS) until after CFIUS's non-notified transaction team investigated the Transaction as a result of a public tip;</P>
                    <P>(d) CFIUS identified national security risks arising from the Transaction relating to the proximity of the Real Estate to Warren AFB, as well as related risk associated with the presence of specialized equipment on the Real Estate used to conduct cryptocurrency mining operations, some of which is foreign-sourced and presents national security concerns;</P>
                    <P>(e) The proximity of the foreign-owned Real Estate to a strategic missile base and key element of America's nuclear triad, and the presence of specialized and foreign-sourced equipment potentially capable of facilitating surveillance and espionage activities, presents a national security risk to the United States;</P>
                    <P>(f) Section 721 authorizes CFIUS to negotiate and enter into an agreement or take certain other actions to mitigate the national security risk arising from a covered transaction. Section 721 also requires that such an agreement be effective and verifiable and enable effective monitoring and enforcement to resolve the national security concerns posed by a transaction. After consideration, CFIUS determined it would not be possible to enter into a negotiated agreement that would satisfy those requirements; and</P>
                    <P>
                        (g) Provisions of law, other than section 721 and the International Emergency Economic Powers Act (50 U.S.C. 1701 
                        <E T="03">et seq.</E>
                        ), do not, in my judgment, provide adequate and appropriate authority for me to protect the national security in this matter.

                         On the basis of the findings set forth in section 1 of this order, considering the factors described in subsection (f) of section 721, as appropriate, and pursuant to my authority under applicable law, including section 721, I hereby order that:
                    </FP>
                    <P>(a) The Transaction is hereby prohibited, and ownership by the Purchasers of any interest in or part of the Real Estate, or maintenance of any property rights in the Real Estate (including but not limited to the rights referred to in 31 CFR 802.233), whether effected directly or indirectly through the Purchasers, through the Purchasers' foreign person shareholders, partners, or beneficial owners, or through the Purchasers' subsidiaries or affiliates, including but not limited to Terra Crypto, Inc., a Wyoming corporation; Terra Global Asset Management Holdings, Inc., a Delaware corporation; Terra Global Capital, LLC, a Delaware limited liability company; Global Network of Business Consultants, Inc., a New York corporation; and International Intellectual Capital, LLC, a Delaware limited liability company (such subsidiaries and affiliates collectively “Affiliates”), are also prohibited.</P>
                    <P>(b) To effectuate this order, not later than 120 calendar days after the date of this order, unless such date is extended by CFIUS, subject to such conditions on an extension as CFIUS determines are necessary and appropriate to protect the national security of the United States, the Purchasers and their Affiliates shall sell or transfer all direct and indirect legal and beneficial ownership interests or other rights in the Real Estate, and certify in writing that such Divestment has been completed (the “Divestment”).</P>
                    <P>(c) Not later than 90 calendar days after the date of this order, unless such date is extended by CFIUS, subject to such conditions on an extension as CFIUS determines are necessary and appropriate to protect the national security of the United States, the Purchasers, whether directly or indirectly, shall:</P>
                    <FP>(i) remove from the Real Estate all items, structures, or other physical objects or installations of any kind (the “Equipment”) that the Purchasers, their Affiliates, or persons acting on their behalf, have stockpiled, stored, deposited, installed, or affixed (the “Equipment Removal”), and certify in writing that such Equipment Removal has been completed; and</FP>
                    <FP>(ii) remove from the Real Estate all (A) utility and other improvements on or adjacent and connected to the Real Estate; (B) excavation, repair, or new construction on the Real Estate underground; and (C) repair, improvement, or new construction on the Real Estate above ground (collectively, (A) through (C), the “Improvements”) commenced, continued, or completed by the Purchasers or their Affiliates after the closing of the Transaction (the “Improvements Removal”), and certify in writing that such Improvements Removal has been completed.</FP>
                    <FP>CFIUS is authorized to require inspection of the Real Estate, at no expense to CFIUS, on terms it deems appropriate to ensure that each of the Equipment Removal and Improvements Removal is complete and verified.</FP>
                    <P>(d) Immediately from the date of this order until such time as the Divestment, Equipment Removal, and Improvements Removal have been completed and verified to the satisfaction of CFIUS, the Purchasers shall, and shall ensure that all of their Affiliates, refrain from physical or logical access to the Real Estate, Equipment, or Improvements, unless such access is necessary to effectuate the requirements of subsections (a) through (c) of this section as determined by CFIUS. Not later than 7 calendar days after the date of this order and until such time as the Divestment, Equipment Removal, and Improvements Removal have been completed and verified to the satisfaction of CFIUS, the Purchasers shall, and shall ensure that their Affiliates, put in place and maintain any measures or controls necessary to ensure that the access prohibited under this subsection does not occur.</P>
                    <P>
                        (e) Until the Divestment, Equipment Removal, and Improvements Removal have been completed and verified to the satisfaction of CFIUS, the Purchasers shall not, and shall ensure that their Affiliates do not, dissolve, reorganize, or transfer their ownership of or any other property rights in the Real 
                        <PRTPAGE P="43303"/>
                        Estate, or otherwise change their legal structure or relocate or sell any physical, intangible, or financial assets in a manner that would materially impede or prevent the Purchasers or their Affiliates from complying with this order. The Purchasers shall, and shall ensure that their Affiliates, notify CFIUS in writing within 24 hours of becoming aware of any actual or potential event of default or other similar occurrence affecting any party's rights or obligations under outstanding loans related to the Real Estate, Equipment, or Improvements that could materially impede or prevent the Purchasers or their Affiliates from complying with this order.
                    </P>
                    <P>(f) Immediately upon completion of the Divestment, Equipment Removal, and Improvements Removal, the Purchasers shall certify in writing to CFIUS that all steps necessary to fully and permanently effectuate the requirements of subsections (a) through (d) of this section, including any related conditions CFIUS imposes pursuant to this order, have been completed in accordance with this order.</P>
                    <P>(g) The Purchasers shall not, and shall ensure that their Affiliates do not, complete a sale or transfer of the Real Estate to any third party:</P>
                    <FP>(i) until the Purchasers notify CFIUS in writing of the intended buyer or transferee; and</FP>
                    <FP>(ii) unless 10 business days have passed from the notification in subsection (g)(i) of this section and CFIUS has not issued to the Purchasers an objection to the intended buyer or transferee. Among the factors CFIUS may consider in reviewing the proposed sale or transfer are whether the buyer or transferee is a United States citizen or is owned by United States citizens and has or has had a direct or indirect contractual, financial, familial, employment, or other close and continuous relationship with the Purchasers or their Affiliates, or officers or employees of the Purchasers or their Affiliates. In addition, CFIUS may consider whether the proposed sale or transfer would threaten to impair the national security of the United States or undermine the purpose of this order, and whether the sale effectuates, to CFIUS's satisfaction and in its discretion, a Divestment consistent with subsection (b) of this section.</FP>
                    <P>(h) From the date of this order until the Purchasers provide a certification of the Divestment to CFIUS pursuant to subsection (f) of this section, each Purchaser shall certify to CFIUS on a weekly basis that it is in compliance with this order and shall include a description of efforts to effectuate the Divestment, Equipment Removal, and Improvements Removal along with a timeline for projected completion of remaining actions.</P>
                    <P>(i) Any transaction or other instrument entered into or method employed for the purpose of, or with the effect of, evading or circumventing this order is prohibited.</P>
                    <P>(j) Without limitation on the exercise of authority by any agency under other provisions of law, and until such time each of the Divestment, Equipment Removal, and Improvements Removal are completed and verified to the satisfaction of CFIUS, CFIUS is authorized to implement measures it deems necessary and appropriate to verify and enforce compliance with this order. For purposes of verifying and enforcing compliance with this order, employees of the United States Government as designated by CFIUS shall be permitted access, on reasonable notice to the Purchasers or their Affiliates, as applicable, to all premises and facilities of the Purchasers or their Affiliates, including the Real Estate, located in the United States:</P>
                    <FP>(i) to inspect and copy any books, ledgers, accounts, correspondence, memoranda, and other records and documents in the possession or under the control of the Purchasers that concern any matter relating to this order;</FP>
                    <FP>
                        (ii) to inspect or audit any information systems, networks, hardware, software, data, communications, or property in the possession or under the control of the Purchasers;
                        <PRTPAGE P="43304"/>
                    </FP>
                    <FP>(iii) to interview officers, employees, or agents of the Purchasers, or any of their respective Affiliates, concerning any matter relating to this order; and</FP>
                    <FP>(iv) to inspect and verify progress or completion of the requirements of subsection (c)(i) and subsection (c)(ii) of this section regarding the Equipment Removal and Improvements Removal.</FP>
                    <FP>CFIUS shall conclude its verification procedures within 90 calendar days after the certification of the Divestment is provided to CFIUS pursuant to subsection (e) of this section.</FP>
                    <P>(k) Without limitation on the exercise of authority by any agency under other provisions of law, and until such time as the Divestment, Equipment Removal, and Improvements Removal are completed and verified to the satisfaction of CFIUS, CFIUS is further authorized to implement measures it deems necessary and appropriate to mitigate risk to the national security of the United States arising from the Transaction, including measures available to it under section 721 and its implementing regulations, which include the remedies available for violations of any agreement or condition entered into or imposed under subsection (l) of section 721.</P>
                    <P>(l) If any provision of this order, or the application of any provision to any person or circumstances, is held by a court of competent jurisdiction to be invalid, the remainder of this order and the application of its other provisions to any other persons or circumstances shall not be affected thereby. If any provision of this order, or the application of any provision to any person or circumstances, is held by a court of competent jurisdiction to be invalid because of the lack of certain procedural requirements, the relevant executive branch officials shall implement those procedural requirements.</P>
                    <P>(m) The Attorney General is authorized to take any steps necessary to enforce this order.</P>
