RIN 2050-AH40


Technical Amendments to the EPCRA Hazardous Chemical Inventory 
Reporting Requirements To Conform to the 2024 OSHA Hazard Communication 
Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency is taking direct final 
action to conform the Emergency Planning and Community Right-to-Know 
Act hazardous chemical inventory reporting regulations to the 
Occupational Safety and Health Administration's Hazard Communication 
Standard amendments of 2012 and 2024. The Emergency Planning and 
Community Right-to-Know Act and its regulations rely on the 
Occupational Safety and Health Administration's Hazard Communication 
Standard for the definition of a hazardous chemical and for the 
categories of health and physical hazards that must be reported under 
the hazardous chemical inventory regulations. This action will conform 
the terminology used and information that must be reported on the 
hazardous chemical inventory forms to the Hazard Communication Standard 
amendments. As a result, this action will also improve first responder 
and community safety, reduce discrepancies and confusion, prevent 
interpretation burdens on facilities when using (Material) Safety Data 
Sheets to complete annual hazardous chemical inventory reports, and 
improve clarity.

DATES: This final rule is effective on January 16, 2026 without further 
notice, unless the EPA receives adverse comment by December 17, 2025. 
If EPA receives adverse comment, we will publish a timely withdrawal in 
the Federal Register informing the public that the rule, or the 
relevant provisions of this rule, will not take effect. Compliance with 
these updates is required for the 2026 annual hazardous chemical 
inventory reporting year. Reports for calendar year 2026 are due on or 
before March 1, 2027.
    Effective date: January 16, 2026.
    Compliance date: December 1, 2026.

I. Why is EPA using a direct final rule?

    The Environmental Protection Agency (``EPA'' or ``Agency'') is 
publishing this rule without a prior proposed rule because the Agency 
views this as a noncontroversial action and anticipates no adverse 
comment because the Emergency Planning and Community Right-to-Know Act 
(EPCRA) statute [42 U.S.C. Chapter 116] \1\ relies on the Occupational 
Safety and Health (OSH) Act of 1970 [29 U.S.C. Chapter 15] \2\ and the 
Occupational Safety and Health Administration's (OSHA's) implementing 
regulations [29 CFR 1910.1200] \3\ for the definitions of hazardous 
chemical, physical hazard, and health hazard and the hazardous chemical 
reporting hazard categories. More specifically, section 311(e) of the 
EPCRA statute and its attendant regulation at 40 CFR 370.66 \4\ define 
hazardous chemical as any hazardous chemical defined under 29 CFR 
1910.1200(c). The EPCRA statute further requires that hazardous 
chemical inventory reporting be grouped into categories of health and 
physical hazards as set forth under the OSH Act and its implementing 
regulations [42 U.S.C. 11021(a)(2)(A)(1) and section 11022(a)(1)]. This 
action adopts the OSHA definitions and hazard categories as is required 
by the EPCRA statute and its regulations. EPA anticipates that this 
action will improve first responder and community safety; prevent 
interpretation burdens for facilities, states, local agencies, and fire 
departments; and improve clarity without increasing the regulatory 
burden under EPCRA. However, in the ``Proposed Rules'' section of this 
Federal Register publication, EPA is publishing a separate document 
that will serve as the proposed rule to solicit comments on the 
amendments incorporated in this direct final rule if adverse comments 
are received on this direct final rule. EPA will not institute a second 
comment period on this action. Any parties interested in commenting 
must do so at this time. For further information about commenting on 
this rule, see the ADDRESSES section of this document.
    If EPA receives adverse comment, the Agency will publish a timely 
withdrawal in the Federal Register informing the public that this 
direct final rule will not take effect. EPA would address all public 
comments in any subsequent final rule based on the proposed rule. If 
the Agency receives adverse comment on a distinct provision of this 
rulemaking, we will publish a timely withdraw in the Federal Register 
indicating which provisions we are withdrawing. The provisions which 
are not withdrawn will become effective on the date set out above, 
notwithstanding adverse comment on any other provision.

II. General Information

A. Summary of This Action

    EPA is amending its hazardous chemical inventory reporting 
regulations at 40 CFR part 370 to conform to OSHA's Hazard 
Communication Standard (HCS) updates of 2012 and 2024 and to make minor 
corrections for plain language, clarity, and consistency.
    In 2012, the OSHA HCS, codified at 29 CFR 1910.1200, was amended to 
adopt the United Nations Globally Harmonized System of Classification 
and Labelling of Chemicals (GHS) [77 FR 17574; March 26, 2012 \5\]. 
Among these 2012 OSHA HCS amendments, OSHA replaced the term Material 
Safety Data Sheet (MSDS) with the term Safety Data Sheet (SDS) and also 
stated that these two terms mean the same thing. In alignment, EPA 
amended its hazardous chemical reporting regulations at 40 CFR part 370 
to conform to these changes [81 FR 38104; June 13, 2016 \6\ and 81 FR 
47311; July 21, 2016 \7\]. The EPA 2016 amendments included adding the 
term SDS to the regulation so that both terms are used together 
throughout 40 CFR part 370. In this action, EPA is removing use of the 
term MSDS to conform to the OSHA HCS and to improve readability of the 
regulation in the following sections: Sec. Sec.  370.3, 370.10, 370.12, 
370.13, 370.14, 370.20, centered heading, 370.30, 370.31, 370.32, 
370.33, 370.60, 370.62, 370.63, and 370.64.
    In 2024, the OSHA HCS, codified at 29 CFR 1910.1200, was further 
amended to conform to revisions of the United Nations Globally 
Harmonized System of Classification and Labelling of Chemicals [89 FR 
44144; May 20, 2024 \8\ and 89 FR 81829; October 9, 2024 \9\]. This 
update improves awareness of chemical hazards by instituting changes as 
to how chemical hazards are reported on SDSs. Hazards reported on SDSs 
are used for reporting hazardous chemical inventories under EPCRA 
sections 311 and 312 [42 U.S.C. 11021 and 11022 \10\]. In this action, 
EPA is amending the EPCRA hazard categories to conform with the 2024 
OSHA HCS and making the conforming amendments to the following 
sections: Sec. Sec.  370.3, 370.30, 370.41, and 370.42.
    The Agency is also making minor plain language, clarifying, and 
consistency corrections in the following sections: Sec. Sec.  370.1, 
370.2, 370.3, 370.10, 370.14, 370.30, 370.32, 370.33, 370.40, 370.41, 
370.42, 370.43, 370.44, 370.45, 370.60, 370.61, 370.62, 370.64, 370.65, 
and 370.66. These corrections include capitalizing each letter of the 
term Extremely Hazardous Substance at Sec.  370.66. Additionally, the 
Agency is moving the definitions for this part from Sec.  370.66 to 
Sec.  370.3, amending the title of Sec.  370.3 to be Definitions, 
amending the title of Sec.  370.66 to be [Reserved], and adding a note 
to Sec.  370.66 that the definitions are now in Sec.  370.3. These 
adjustments add clarity to the regulation by providing definitions of 
key words prior to the requirements. Further, EPA is removing the 
historic compliance dates from Sec.  370.33 and Sec.  370.45, as well 
as removing the historic clarifications for electronic reporting from 
Sec.  370.41 and Sec.  370.42. These removals improve the readability 
of the regulation by removing irrelevant information.

B. Who does this regulation apply to?

    Sections 311 and 312 of the EPCRA statute, and its implementing 
regulations at 40 CFR part 370, apply to the owners and operators of 
facilities that are required to prepare or have an SDS for any 
hazardous chemical defined under the OSHA HCS and its implementing 
regulations. EPCRA section 311(e) defines the term hazardous chemical 
to have the same meaning as in 29 CFR 1910.1200(c), except for certain 
substances exempted in EPCRA section 311(e) [42 U.S.C. 11021(e)]. If 
you have questions regarding the applicability of this action to a 
particular entity, consult the person listed in the FOR FURTHER 
INFORMATION CONTACT section.

C. What does this regulation require from facilities?

    The regulations found at 40 CFR part 370 codify the statutory 
requirements of EPCRA sections 311 and 312. These EPCRA hazardous 
chemical inventory reporting requirements were first promulgated in 
1987 [53 FR 38344; October 15, 1987].\11\ Section 311 requires that 
facilities submit SDSs of hazardous chemicals or a list of hazardous 
chemicals grouped into categories of health and physical hazards as 
defined in OSHA's HCS to the State Emergency Response Commission 
(SERC), Local Emergency Planning Committee (LEPC), and local fire 
department with jurisdiction over the facility. This is a one-time 
submittal with resubmission requirements if there is significant new 
information for existing hazardous chemicals, new hazardous chemicals 
present at the facility, or upon request by the LEPC as

[[Page 51189]]

required at 40 CFR 307.31. Section 312 requires that facilities submit 
an emergency and hazardous chemical inventory form to the SERC, LEPC, 
and local fire department, by March 1st annually. The inventory form 
provides the health and physical hazards of each hazardous chemical as 
well as the locations and quantities present at the facility during the 
previous calendar year. There are two reporting tiers, Tier I and Tier 
II.
    SERCs provide direction for facilities in their states for whether 
a Tier I or a Tier II form is required to be submitted. Currently, all 
states require use of the Tier II inventory form, which provides 
specific information on each hazardous chemical for developing and 
maintaining local emergency response plans. The Tier I inventory form 
provides only general information on hazardous chemicals and is 
currently not accepted by any state for reporting under the EPCRA 
section 312.
    Note that the term SERC includes Tribal Emergency Response 
Commissions (TERCs) and the term LEPC includes any Tribal Emergency 
Planning Committees (TEPCs). Facilities on Tribal lands need to verify 
with their Tribe which SERC or TERC, LEPC or TEPC, and fire department 
to submit the EPCRA 311 and 312 hazardous chemical inventory reports 
to. [55 FR 3062; July 26, 1990] \12\

D. Why is the Agency taking this action?

    EPA is taking this action to meet its responsibilities as the 
Administrator of the EPCRA statute [42 U.S.C. 11049(1)] by ensuring 
that the hazardous chemical inventory reporting requirements are in 
conformance with the OSHA HCS SDS requirements, publishing a uniform 
format for inventory forms using OSHA SDS hazard categories, and 
ensuring that the regulations are clearly written. EPA anticipates that 
coordination with the OSHA HCS and GHS will provide greater clarity to 
the regulated community and facilitate emergency planning.

E. What is the Agency's authority for taking this action?

     42 U.S.C. 11021(a)(2)(A)(i) states that the EPCRA section 
311 list of hazardous chemicals report shall be grouped into categories 
of health and physical hazards as set forth under the OSH Act and the 
OSHA HCS, or in other categories as EPA may prescribe under 
subparagraph (B).
     42 U.S.C. 11021(a)(2)(B) states that, for the EPCRA 
section 311 list of hazardous chemicals report, EPA may modify the 
categories of health and physical hazards as set forth under the OSH 
Act and the OSHA HCS by requiring information to be reported in terms 
of groups of hazardous chemicals which present similar hazards in an 
emergency.
     42 U.S.C. 11022(d)(1)(C) states that, for the EPCRA 
section 312 annual hazardous chemical inventory forms, EPA may modify 
the OSH Act and OSHA HCS categories of health and physical hazards by 
requiring information to be reported in terms of groups of hazardous 
chemicals which present similar hazards in an emergency.
     42 U.S.C. 11022(g) states that for the EPCRA section 312 
annual hazardous chemical inventory forms, EPA shall publish a uniform 
format for inventory forms.
     42 U.S.C. 11049(1) states that the term Administrator used 
throughout the statute means the Administrator of the Environmental 
Protection Agency.

F. What are the incremental costs and benefits of this action?

    This action does not create any additional requirements on affected 
facilities. EPA also anticipates that this action will improve first 
responder and community safety; prevent interpretation burdens for 
facilities, states, local agencies, and fire departments; and improve 
clarity without increasing the regulatory burden.

III. Revisions to 40 CFR Part 370

A. History of EPCRA Hazard Categories

    The EPCRA statute specifies that the hazardous chemical inventory 
reporting under sections 311 and 312 should be based on the health and 
physical hazard categories established under the OSH Act and the OSHA 
HCS regulations and that EPA may modify those hazards. Accordingly, in 
1987, EPA modified OSHA's 23 health and physical hazards into five 
hazard categories (two health and three physical hazard categories) for 
facilities to use for reporting and codified the requirements at 40 CFR 
part 370. Facilities used the following five categories for EPCRA 
hazardous chemical inventory reporting from 1987 to 2016: (1) Immediate 
(acute) health hazard, including highly toxic, toxic, irritant, 
sensitizer, corrosive, and other hazardous chemicals that cause an 
adverse effect to a target organ and which effect usually occurs 
rapidly as a result of short-term exposure and is of short duration; 
(2) Delayed (chronic) health hazard, including carcinogens and other 
hazardous chemicals that cause an adverse effect to a target organ and 
which effect generally occurs as a result of long-term exposure and is 
of long duration; (3) Fire hazard, including flammable, combustible 
liquid, pyrophoric, and oxidizer; (4) Sudden release of pressure, 
including explosive and compressed gas; and (5) Reactive, including 
unstable reactive, organic peroxide, and water reactive. [53 FR 38344; 
October 15, 1987]
    In 2016, EPA conformed the EPCRA regulations at 40 CFR part 370 
with the 2012 OSHA HCS. The 2012 OSHA HCS adopted the GHS to establish 
consistent and standardized hazard communications and required the 
development of SDSs with a standardized 16-section format. The EPA's 
conforming action included replacing the five EPCRA hazard categories 
established in 1987 with the 2012 OSHA HCS hazard classes, as listed 
within the definitions of health hazard and physical hazard, as well as 
the four hazards that the GHS did not address (simple asphyxiant, 
combustible dust, pyrophoric gas, and hazard not otherwise classified) 
but are included in the 2012 OSHA HCS definition of a hazardous 
chemical. In the 2016 preamble, EPA discussed that the 2012 OSHA HCS 
divides the OSHA hazard classes into categories, stating that the 
detailed criteria would be valuable for emergency planners and first 
responders, but did not incorporate the hazard categories into the 
EPCRA hazardous chemical inventory reports. [81 FR 47311; July 21, 
2016] The following table lists the EPCRA hazard categories, as was 
published in 40 CFR 370.66 from 2016 until the compliance date 
(December 1, 2026) of this action:

            EPCRA Hazard Categories Based on OSHA Definitions

------------------------------------------------------------------------

B. Revisions to EPCRA hazard categories

    In 2024, OSHA amended the HCS to conform with the GHS (primarily to 
GHS Revision 7, published in 2017). The 2024 OSHA HCS modifications 
that affect EPCRA include revised criteria for the classification of 
certain physical hazards to better capture and communicate the hazards 
to downstream users and amended contents for Section 2. Hazard 
Identification of SDSs. [89 FR 44144; May 20, 2024]
    The following is a list of the revised criteria affecting EPCRA: 
(1) replacement of the hazard class Flammable Aerosols with Aerosols 
and Chemicals Under Pressure; (2) addition of the hazard class 
Desensitized Explosives; (3) inclusion of pyrophoric and chemically 
unstable gases \13\ within the definition of Flammable Gases; and (4) 
removal of pyrophoric gases from the definition of hazardous chemical. 
These modifications also affect the definitions of health hazards and 
physical hazards at 40 CFR 370.66, which are being moved to 40 CFR 
370.3 in this action. The following discusses these changes to the OSHA 
hazard classes and the conforming amendments to the EPCRA regulation at 
40 CFR part 370.
    The 2024 OSHA HCS replaces the Flammable Aerosols hazard class with 
two hazard classes Aerosols and Chemicals Under Pressure. These two 
hazard classes are both divided into three hazard categories (two for 
flammables and one for non-flammable). [89 FR 44321-44324; May 20, 
2024] This HCS modification groups substances with different hazards 
for first responders into the same hazard class. For example, non-
refillable fire extinguishers would be classified as Aerosol--Category 
3, where highly flammable paints would be Aerosols--Category 1.
    To align with this modification while ensuring the protection of 
first responders and communities, the EPCRA regulation will directly 
incorporate the OSHA hazard categories as opposed to the current method 
of being based on the summaries of hazard classes as provided in the 
OSHA definitions at 29 CFR 1910.1200(c) for hazardous chemical, health 
hazard, and physical hazard. The current method groups together 
similarly named hazard classes rather than the OSHA hazard categories. 
The current EPCRA hazard categories that are groupings of multiple OSHA 
hazard classes are acute toxicity (any route of exposure), flammable 
(gases, aerosols, liquids, or solids), gas under pressure (compressed 
gas), oxidizer (liquid, solid or gas), and pyrophoric (liquid or 
solid). There are currently 24 EPCRA hazard categories; this action 
simply incorporates the 112 OSHA hazard categories as the EPCRA hazard 
categories. These more detailed hazard categories provide more accurate 
hazard information. This increased specificity for the risk criteria 
will be valuable to emergency planners and responders, while allowing 
facilities to simply copy the hazard categories from the SDSs to the 
EPCRA inventory reports. Modifying the EPCRA regulations to use the 
OSHA hazard categories is in direct alignment with the statutory 
sections 42 U.S.C. 11021(a)(2)(A)(i) and section 11022(d)(C)(i), which 
state that the EPCRA hazardous chemical inventory reporting should be 
based on the categories of health and physical hazards as set forth 
under the OSH Act and its regulations.
    The following table compares the current EPCRA hazard categories to 
the 2024 OSHA HCS hazard classes and their hazard categories:

    Summary of changes to hazard categories--
    In direct alignment with the EPCRA statute, which requires that the 
EPCRA hazardous chemical reporting be for OSHA hazardous chemicals and 
be grouped into categories of health and physical hazards [42 U.S.C. 
11021(a)(2)(A)(i) and section 11022(d)(C)(i)], EPA is amending the 
EPCRA hazard categories to include the full list of OSHA hazard classes 
with their categories for the health and physical hazards. Previously, 
EPA used the abbreviated list of OSHA hazard classes as was defined 
under the terms hazardous chemical, health hazard, and physical hazard 
within 29 CFR 1910.1200(c).
    EPA will continue to include the hazard classes that are listed in 
the OSHA HCS definition of hazardous chemical as health and/or physical 
hazard classes: simple asphyxiants will remain a health hazard, 
combustible dust will remain a physical hazard, and hazard not 
otherwise classified will remain both a physical hazard and a health 
hazard [81 FR 38107; June 13,2016]. Because these classes do not have 
hazard categories in the appendices of 29 CFR 1910.1200, the hazard 
class will also be the hazard category for EPCRA reporting purposes. 
This is also in agreement with the OSHA guidance document Hazard 
Classification Guidance [OSHA 3844-02 2016].\14\
    These changes will ensure that first responders and communities are 
aware of the hazards present at facilities, while maintaining the 
reporting burden reduction achieved in the 2016 amendments by ensuring 
that facilities only need to copy the chemical hazard information from 
the SDSs to the EPCRA inventory forms [81 FR 38107; June 13, 2016]. The 
following tables compare the current EPCRA hazard categories (adopted 
in 2016) to the hazard categories which are being adopted in this 
action:

C. Revisions to EPCRA Definitions

    EPA is amending the definition of hazard category and removing the 
definition of Material Safety Data Sheet to conform with the 2024 OSHA 
HCS. EPA also notes that OSHA added a definition for combustible dust 
to the 2024 OSHA HCS. Further, the Agency is moving the definitions for 
40 CFR part 370 from Sec.  370.66 to Sec.  370.3 to ensure clarity and 
consistency within the EPCRA regulations.
    Hazard category--
    EPA is amending the definition of hazard category in 40 CFR part 
370, including the health and physical hazard definitions, to implement 
the conforming amendments discussed above in section B. Revisions to 
EPCRA Hazard Categories. This action amends the definition of hazard 
category to state that under EPCRA, a hazard category is the OSHA HCS's 
classification of a chemical's hazard(s) into classes with their 
categories as are reported in Section 2 of SDSs in accordance with 29 
CFR 1910.1200. In accordance with the EPCRA statute [42 U.S.C. 
11021(a)(2)(A)(1) and section 11022(a)(1)], the hazard categories 
continue to be divided by their hazard class into those with health and 
physical hazards. The definitions for health hazard and physical hazard 
are being amended to list each of the hazard classes as are described 
and named in Appendices A and B of 29 CFR 1910.1200 or 29 CFR 
1910.1200(c) for combustible dust, simple asphyxiant, and hazards not 
otherwise classified, as well as to alphabetize the hazard classes to 
improve functionality and reduce the burden of completing the inventory 
forms.
    The following table compares the definition for hazard category, 
including health hazard and physical hazard, between the 2016 EPCRA 
regulation and this action, with differences in language bolded:

                                      reactive chemicals; and hazard not
                                      otherwise classified (HNOC).
------------------------------------------------------------------------

    (Material) Safety Data Sheet--
    The 2012 OSHA HCS replaced the term Material Safety Data Sheet 
(MSDS) with the term Safety Data Sheet (SDS) and also stated that these 
two terms mean the same thing, serve the same function, and communicate 
the same types of information. Additionally, OSHA stated that an SDS 
should be treated as an MSDS under EPCRA. [77 FR 17730; March 26, 2012] 
Further, the 2012 and 2024 OSHA HCS at 29 CFR 1910.1200 do not contain 
the term Material Safety Data Sheet or MSDS, nor do they provide a 
reference to the prior use of this term.
    The EPCRA statute defines and references the term Material Safety 
Data Sheet and its acronym MSDS, stating that the document is required 
to be prepared or made available for a hazardous chemical under the OSH 
Act of 1970 and the OSHA HCS at 29 CFR 1910.1200 [42 U.S.C. 11021(a)(1) 
and 11049(6)]. In 2016, EPA amended 40 CFR part 370 to use both terms 
and their acronyms, stating that the terms mean the same thing and that 
more stakeholders commonly use the term SDS. EPA finds that the use of 
both terms in the regulation is cumbersome to read and unnecessary, as 
it is well documented by OSHA and EPA that these terms refer to the 
same document and that document is what is required by EPCRA. 
Therefore, to better align the hazardous chemical inventory reporting 
regulations with the OSHA HCS, EPA is removing the definition for 
Material Safety Data Sheet (MSDS) and use of the term within the 
regulation and is also amending the definition of Safety Data Sheet 
(SDS) for consistency and added clarity that the term SDS replaces the 
term MSDS for the required data sheet.
    The following table provides the current and revised definition of 
Safety Data Sheet, which are being moved from Sec.  370.66 to Sec.  
370.3 in this action, with the modified language in bold.

------------------------------------------------------------------------
                                      Adopting in this action EPCRA 311-
 2016 EPCRA 311-312  40 CFR 370.66            312  40 CFR 370.3
------------------------------------------------------------------------
Safety Data Sheet or SDS means the   Safety Data Sheet (SDS) means the
 sheet required to be developed       sheet required to be developed
 under 29 CFR 1910.1200(g). This      under 29 CFR 1910.1200(g). This
 term means the same as the term      term SDS replaces the term
 ``material safety data sheet or      ``material safety data sheet'' for
 MSDS'' defined in this section.      the name of the data sheet defined
                                      in the statute [42 U.S.C.
                                      11049(6)].
------------------------------------------------------------------------

    Combustible dust--
    The 2024 OSHA HCS includes the following definition of combustible 
dust at 29 CFR 1910.1200(c): ``Combustible dust means finely divided 
solid particulates of a substance or mixture that pose a flash-fire 
hazard or explosion hazard when dispersed in air or other oxidizing 
media.'' [89 FR 44272-44274; May 20, 2024] EPA notes that the 2024 OSHA 
HCS definition of combustible dusts is applicable to 40 CFR part 370 by 
the existing reference to the OSHA HCS within the definition of 
hazardous chemical at 40 CFR 370.66. EPA is not making amendments to 
further incorporate this definition.
    Location of definitions in 40 CFR part 370--
    Additionally, through this action, the Agency is moving the 
definitions for this part from Sec.  370.66 to Sec.  370.3, amending 
the title of Sec.  370.3 to be Definitions, amending the title of Sec.  
370.66 to be [Reserved], and adding a note to Sec.  370.66 that the 
definitions are now in Sec.  370.3. This adjustment adds clarity to the 
regulation by providing key words prior to the requirements and is 
consistent with the Agency's common practice.

D. Other Revisions to 40 CFR Part 370

    In this action, EPA is capitalizing each letter of the term 
Extremely Hazardous Substance to add clarity between the distinct set 
of substances listed in the appendices to 40 CFR part 355 and the broad 
use of the term extremely hazardous substance within the Clean Air Act 
(CAA) 112(r) programs [42 U.S.C. 7412(r)]. This distinction is 
necessary to reduce confusion as there is interplay between the EPCRA 
and CAA 112(r) statutes, regulations, and stakeholders.
    In this action, EPA is also making minor plain language, 
clarifying, and consistency edits in the following sections: Sec. Sec.  
370.1, 370.2, 370.3, 370.10, 370.14, 370.30, 370.32, 370.33, 370.40, 
370.41, 370.42, 370.43, 370.44, 370.45, 370.60, 370.61, 370.62, 370.64, 
370.65, and 370.66. These changes include removing the historic 
compliance dates from Sec.  370.33 and Sec.  370.45, as well as 
removing the historic clarifications for electronic reporting from 
Sec.  370.41 and Sec.  370.42.

IV. Statutory and Executive Orders Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was 
therefore not submitted to the Office of Management and Budget (OMB) 
for review.

B. Executive Order 14192: Unleashing Prosperity Through Deregulation

    This action is considered a deregulatory action under Executive 
Order 14192. This action provides burden reduction by directly adopting 
OSHA definitions and hazard categories as the EPCRA definitions and 
hazard categories and also by making plain language, clarifying, and 
consistency edits to improve the readability and add clarity to the 
regulation. By directly adopting the OSHA definitions and hazard 
categories, this action should reduce administrative costs by 
preventing interpretation burdens on facilities when using Safety Data 
Sheets to complete annual hazardous chemical inventory reports. By 
improving the readability and adding clarity, this action should reduce 
the burden to read and understand the regulations. This rule will also 
improve first responder and community safety, thereby extending the 
deregulatory benefits of EPA's approach to state and local governments. 
Overall, this action will have total costs of less than zero.

C. Paperwork Reduction Act (PRA)

    The information collection activities in this direct final rule 
will be submitted for approval to the Office of Management and Budget 
(OMB) under the PRA through a revision Information

[[Page 51198]]

Collection Request (ICR) [EPA ICR number 1352.18; OMB Control Number 
2050-0072] to be announced, shared via docket, and made available for a 
60-day public comment period in a subsequent Federal Register Notice. 
The information collection requirements are not enforceable until OMB 
approves them.
    This rulemaking action will conform the terminology used, and 
information that must be reported, on the hazardous chemical inventory 
forms to the Occupational Safety and Health Administration's Hazard 
Communication Standard amendments of 2012 and 2024. This action will 
result in burden reductions by removing interpretation burdens on 
facilities using the SDS to complete annual hazardous chemical 
inventory reports and reducing the burden to read and understand the 
regulations. The burden for the existing EPA information collection 
activities is accounted for in the EPA ICR number 1352.16 under OMB 
Control Number 2050-0072. You can find a copy of the existing approved 
ICR in Docket ID: EPA-HQ-SFUND-2004-0006.
    An agency may not conduct or sponsor (and a person is not required 
to respond to) a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB 
approves this ICR, the Agency will announce that approval in the 
Federal Register and publish a technical amendment to 40 CFR part 9 to 
display the OMB control number for the approved information collection 
activities contained in this final rule.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. In 
making this determination, the EPA concludes that the impact of concern 
for this rule is any significant adverse economic impact on small 
entities and that the agency is certifying that this rule will not have 
a significant economic impact on a substantial number of small entities 
because the rule imposes no added burden on the small entities subject 
to the rule. This action is modifying the hazard categories used for 
the existing reporting requirements. The burden for reporting is not 
being modified by this action. We have therefore concluded that this 
action will have no net regulatory burden for all directly regulated 
small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million 
(adjusted annually for inflation) or more (in 1995 dollars) as 
described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or 
uniquely affect small governments. The action implements mandate(s) 
specifically and explicitly set forth in the EPCRA statute [42 U.S.C. 
Chapter 116] without the exercise of any policy discretion by the EPA.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. 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.

G. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have Tribal implications as specified in 
Executive Order 13175. It will not have substantial direct effects on 
one or more Indian Tribes, on the relationship between the Federal 
Government and Indian Tribes, or on the distribution of power and 
responsibilities between the Federal Government and Indian Tribes. 
Thus, Executive Order 13175 does not apply to this action.

H. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    Executive Order 13045 directs federal agencies to include an 
evaluation of the health and safety effects of the planned regulation 
on children in federal health and safety standards and explain why the 
regulation is preferable to potentially effective and reasonably 
feasible alternatives. This action is not subject to Executive Order 
13045 because it is not a significant regulatory action under section 
3(f)(1) of Executive Order 12866, and because the EPA does not believe 
the environmental health or safety risks addressed by this action 
present a disproportionate risk to children. Further, this action is 
not subject to the EPA's Children's Health Policy (https://www.epa.gov/children/childrens-health-policy-and-plan) because EPA does not believe 
the action has considerations for human health.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution or Use

    This action is not subject to Executive Order 13211, because it is 
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, 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).

Subpart A--General Information


Sec.  370.1   What is the purpose of this part?

    (a) This part (40 CFR part 370) establishes reporting requirements 
for providing the public with important information on the hazardous 
chemicals in their communities. Reporting raises community awareness of 
chemical hazards and aids in the development of state and local 
emergency response plans. The reporting requirements established under 
this part consist of Safety Data Sheet (SDS) reporting and inventory 
reporting.
    (b) This part is written in a special format to make it easier to 
understand the regulatory requirements. Like other Environmental 
Protection Agency (EPA) regulations, this part establishes enforceable 
legal requirements. Information considered non-binding guidance under 
EPCRA is indicated in this regulation by the word ``note'' and a 
smaller typeface. Such notes are provided for information purposes only 
and are not considered legally binding under this part.


Sec.  370.2   Who do the terms you, I, and your refer to in this part?

    Throughout this part the terms you, I, and your refer to the owner 
or operator of a facility.

Subpart B--Who Must Comply


Sec.  370.10   Who must comply with the hazardous chemical reporting 
requirements of this part?

    (a) You must comply with the reporting requirements of this part if 
the Occupational Safety and Health Administration's (OSHA) Hazard 
Communication Standard (HCS) requires your facility to prepare or have 
available a Safety Data Sheet (SDS) for a hazardous chemical and if 
either of the following conditions is met:
    Note 1 to paragraph (a) introductory text. OSHA's Material Safety 
Data Sheet or MSDS requirement was renamed to be the Safety Data Sheet 
or SDS requirement. The terms MSDS and SDS are synonymous. The EPCRA 
statutory MSDS requirements will be referred to as the SDS requirements 
within this regulation. [29 CFR 1910.1200]
    (1) A hazardous chemical that is an Extremely Hazardous Substance 
(EHS) is present at your facility at any one time in an amount equal to 
or greater than 500 pounds (227 kg--approximately 55 gallons) or the 
Threshold Planning Quantity (TPQ), whichever is lower. EHSs and their 
TPQs are listed in Appendices A and B of 40 CFR part 355.
    (2) A hazardous chemical that is not an EHS is present at your 
facility at any one time in an amount equal to or greater than the 
threshold level for that hazardous chemical. Threshold levels for such 
hazardous chemicals are:
    (i) For any hazardous chemical that does not meet the criteria in 
paragraph (a)(2)(ii) or (iii) of this section, the threshold level is 
10,000 pounds (or 4,540 kg).
    (ii) For gasoline at a retail gas station (For purposes of this 
part, retail gas station means a retail facility engaged in selling 
gasoline and/or diesel fuel principally to the public for motor vehicle 
use on land.), the threshold level is 75,000 gallons (approximately 
283,900 liters) (all grades combined). This threshold is only 
applicable for gasoline that was in tanks entirely underground and that 
were in compliance at all times during the preceding calendar year with 
all applicable Underground Storage Tank (UST) requirements at 40 CFR 
part 280 or requirements of the state UST program approved by the 
Agency under 40 CFR part 281.
    (iii) For diesel fuel at a retail gas station (For purposes of this 
part, retail gas station means a retail facility engaged in selling 
gasoline and/or diesel fuel principally to the public for motor vehicle 
use on land.), the threshold level is 100,000 gallons (approximately 
378,500 liters) (all grades combined). This threshold is only 
applicable for diesel fuel that was in tanks entirely underground and 
that were in compliance at all times during the preceding calendar year 
with all applicable UST requirements at 40 CFR part 280 or requirements 
of the state UST program approved by the Agency under 40 CFR part 281.
    (b) The threshold level for responding to the following requests is 
zero.
    (1) If your LEPC requests that you submit an SDS for a hazardous 
chemical for which you have not submitted an SDS to your LEPC; or
    (2) If your LEPC, SERC, or the fire department with jurisdiction 
over your facility requests that you submit Tier II information.


Sec.  370.11  [Reserved]


Sec.  370.12  What hazardous chemicals must I report under this part?

    (a) You must report any hazardous chemical for which you are 
required to prepare or have available an SDS under OSHA HCS that is 
present at your facility equal to or above the applicable threshold 
specified in Sec.  370.10. (Specific exemptions from reporting are in 
Sec.  370.13.)
    (b) The EPA has not issued a list of hazardous chemicals subject to 
reporting under this part. A substance is a hazardous chemical if it is 
required to have an SDS and meets the definition of hazardous chemical 
under the OSHA regulations found at 29 CFR 1910.1200(c).

[[Page 51201]]

Sec.  370.13  What substances are exempt from these reporting 
requirements?

    You do not have to report substances for which you are not required 
to have an SDS under the OSHA regulations or that are excluded from the 
definition of hazardous chemical under EPCRA section 311(e). Each of 
the following substances are excluded under EPCRA section 311(e):
    (a) Any food, food additive, color additive, drug, or cosmetic 
regulated by the Food and Drug Administration.
    (b) Any substance present as a solid in any manufactured item to 
the extent exposure to the substance does not occur under normal 
conditions of use.
    (c) Any substance to the extent it is used:
    (1) For personal, family, or household purposes, or is present in 
the same form and concentration as a product packaged for distribution 
and use by the general public. Present in the same form and 
concentration as a product packaged for distribution and use by the 
general public means a substance packaged in a similar manner and 
present in the same concentration as the substance when packaged for 
use by the general public, whether or not it is intended for 
distribution to the general public or used for the same purpose as when 
it is packaged for use by the general public;

----------------------------------------------------------------------------------------------------------------

    (b) For each specific mixture, the reporting option used must be 
consistent for both SDS and inventory reporting, unless it is not 
possible to do so. This means that if you report on a specific mixture 
as a whole for SDS reporting, you must report on that mixture as a 
whole for inventory reporting too (unless it is not possible). SDS 
reporting and inventory reporting are discussed in detail in subpart C 
of this part.
    (c) To determine the quantity of an EHS or a non-EHS hazardous 
chemical component present in a mixture, multiply the concentration of 
the hazardous chemical component (in weight percent) by the weight of 
the mixture (in pounds). You do not have to count a hazardous chemical 
present in a mixture if the concentration is less than or equal to 1%, 
or less than or equal to 0.1% for a carcinogenic chemical.

Sec.  370.60  How does a person obtain SDS information about a specific 
facility?

    Any person may obtain an SDS for a specific facility by writing to 
the LEPC and asking for it.
    (a) If the LEPC has the SDS it must provide it to the person making 
the request.
    (b) If the LEPC does not have the SDS it must request it from the 
facility's owner or operator.


Sec.  370.61  How does a person obtain inventory information about a 
specific facility?

    (a) Any person may request Tier II information for a specific 
facility by writing to the SERC or LEPC.
    (1) If the SERC or LEPC has the Tier II information, the SERC or 
LEPC must provide it to the person making the request.
    (2) If the SERC or LEPC does not have the Tier II information, it 
must request it from the facility owner or operator in either of the 
following cases:
    (i) The person making the request is a state or local official 
acting in an official capacity.
    (ii) The request is for hazardous chemicals in amounts greater than 
10,000 pounds stored at the facility at any time during the previous 
calendar year.
    (3) If the SERC or LEPC does not have the Tier II information, it 
may request it from the facility owner or operator when neither 
condition in paragraph (a)(2) of this section is met but the person's 
request includes a general statement of need.
    (b) A SERC or LEPC must respond to a request for Tier II 
information under this section within 45 days of receiving such a 
request.


Sec.  370.62  What information may a state or local official request 
from a facility?

    The LEPC may ask a facility owner or operator to submit an SDS for 
a hazardous chemical present at the facility. The SERC, LEPC, or fire 
department with jurisdiction over a facility may ask a facility owner 
or operator to submit Tier II information. The owner or operator must 
provide the SDS (unless the owner or operator has already submitted an 
SDS to the LEPC for that hazardous chemical) or Tier II information 
within 30 days of receipt of such request.


Sec.  370.63  What responsibilities do the SERC and LEPC have to make 
request information available?

    Under this subpart, the SERC or LEPC must make the following 
information (except for confidential location information discussed in 
Sec.  370.64(b)) available if a person requests it:
    (a) All information obtained from an owner or operator in response 
to a request under this subpart.
    (b) Any requested Tier II information or SDS otherwise in 
possession of the SERC or the LEPC.


Sec.  370.64  What information can I claim as trade secret or 
confidential?

    (a) Trade secrets. You may be able to withhold the name of a 
specific chemical when submitting SDS reporting or inventory reporting 
information if that chemical name is claimed as a trade secret. The 
requirements for withholding trade secret information are set forth in 
EPCRA section 322 and implemented in 40 CFR part 350. If you are 
withholding the name of a specific chemical as a trade secret in 
accordance with trade secrecy requirements, you must report the generic 
class or category that is structurally descriptive of the chemical 
along with all other required information. You must also submit the 
withheld information to EPA and must adequately substantiate your 
claim. A Form for substantiating trade secret claims is available at 
the Agency website at https://www.epa.gov/epcra.
    (b) Confidential location information. You may request that the 
SERC and LEPC not disclose to the public the location of any specific 
chemical required to be submitted in Tier II information. If you make 
such a request, the SERC and LEPC must not disclose the location of the 
specific chemical. Although you may request that location information 
(with respect to a specific chemical) be withheld from the public, you 
may not withhold this information from the SERC, LEPC, and the local 
fire department. If you use the Tier II Form to report your inventory 
information, you can choose to report the confidential location 
information for the specific chemical on the Tier II Confidential 
Location Form and attach this form to the other Tier II information you 
are reporting. The Tier II Confidential Location Form is available on 
the Agency website at https://www.epa.gov/epcra.


Sec.  370.65   Must I allow the local fire department to inspect my 
facility, and must I provide specific location information about 
hazardous chemicals at my facility?

    If you are the owner or operator of a facility that has submitted 
inventory information under this part, you must comply with the 
following two requirements upon request by the fire department with 
jurisdiction over your facility:
    (a) You must allow the fire department to conduct an on-site 
inspection of your facility; and
    (b) You must provide the fire department with information about the 
specific locations of hazardous chemicals at your facility.
