Abstract
The Environmental Protection Agency (EPA) is updating the list of chemicals subject to toxic chemical release reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). Specifically, this action updates the regulations to identify nine per- and polyfluoroalkyl substances (PFAS) that must be reported pursuant to the National Defense Authorization Act for Fiscal Year 2020 (FY2020 NDAA) enacted on December 20, 2019. As this action is being taken to conform the regulations to a Congressional legislative mandate, notice and comment rulemaking is unnecessary.

determine whether your facility would be affected by this action, you
should carefully examine the applicability criteria in 40 CFR part 372,
subpart B. If you have questions regarding the applicability of this
action to a particular entity, consult the person listed under FOR
FURTHER INFORMATION CONTACT.
B. What action is the Agency taking?
EPA is codifying the addition of the nine PFAS added to the EPCRA
section 313 list of reportable chemicals (more commonly known as the
Toxics Release Inventory (TRI)) since the last conforming rule pursuant
to the FY2020 NDAA ((89 FR 43331; May 17, 2024) (FRL-9427.1-01-OCSPP)).
C. What is the Agency's authority for taking this action?
This action is issued under authority of EPCRA section 313 (42
U.S.C. 11001 et seq.), PPA section 6607 (42 U.S.C. 13106), and FY2020
NDAA section 7321 (Pub. L. 116-92).
II. Background
A. What is NDAA Section 7321?
The FY2020 NDAA was signed into law on December 20, 2019. Among
other provisions, section 7321(c) identifies certain regulatory
activities that automatically add PFAS or classes of PFAS to the EPCRA
section 313 list of reportable chemicals. PFAS or classes of PFAS shall
be added to the EPCRA
[[Page 574]]
section 313 list of reportable chemicals beginning January 1 of the
calendar year after any one of the following dates:
<bullet> Final Toxicity Value. The date on which the Administrator
finalizes a toxicity value for the PFAS or class of PFAS;
<bullet> Significant New Use Rule. The date on which the
Administrator makes a covered determination for the PFAS or class of
PFAS;
<bullet> Addition to Existing Significant New Use Rule. The date on
which the PFAS or class of PFAS is added to a list of substances
covered by a covered determination;
<bullet> Addition as an Active Chemical Substance. The date on
which the PFAS or class of PFAS to which a covered determination
applies is:
(1) Added to the list published under section 8(b)(1) of the Toxic
Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.) and designated
as an active chemical substance under TSCA section 8(b)(5)(A); or
(2) Designated as an active chemical substance under TSCA section
8(b)(5)(B) on the list published under TSCA section 8(b)(1).
The FY2020 NDAA defines ``covered determination'' as a
determination made by rule under TSCA section 5(a)(2) that a use of a
PFAS or class of PFAS is a significant new use (except such a
determination made in connection with a determination described in TSCA
sections 5(a)(3)(B) or 5(a)(3)(C)).
Under FY2020 NDAA section 7321(e), EPA must review confidential
business information (CBI) claims before PFAS are added to the list
pursuant to FY2020 NDAA sections 7321(b)(1), (c)(1), or (d)(3) whose
identities are subject to a claim of protection from disclosure under 5
U.S.C. 552(a), pursuant to 5 U.S.C. 552(b)(4). Under the FY2020 NDAA
EPA must:
<bullet> Review a claim of protection from disclosure; and
<bullet> Require that person to reassert and substantiate or re-
substantiate that claim in accordance with TSCA section 14(f) (15
U.S.C. 2613(f)).
In addition, if EPA determines that the chemical identity of a PFAS
or class of PFAS qualifies for protection from disclosure, EPA must
include the PFAS or class of PFAS on the TRI in a manner that does not
disclose the protected information.
B. What PFAS have been added to the TRI list?
EPA has reviewed the above-listed criteria and found nine chemicals
that meet the requirements of this part of the FY2020 NDAA and have an
identity not claimed as CBI.

------------------------------------------------------------------------
* CASRN means Chemical Abstracts Service Registry Number.
Under FY2020 NDAA section 7321(e), EPA must review CBI claims
before PFAS with identities subject to a claim of protection from
disclosure under 5 U.S.C. 552(a) (pursuant to 5 U.S.C. 552(b)(4)) are
added to the list. The substance with the CASRN 3030471-22-5 met the
criteria under FY2020 NDAA section 7321(c)(1)(A)(iii) but was subject
to a claim of protection from disclosure under 5 U.S.C. 552(b)(4) at
that time (i.e., when the FY2020 NDAA was enacted). This substance's
identity was published on the non-confidential portion of the TSCA
Inventory in 2024; therefore, pursuant to FY2020 NDAA section 7321(e)
the chemical was added to the TRI list and is being codified in the CFR
by this rulemaking.
As established by the FY2020 NDAA, the addition of these PFAS to
the EPCRA section 313 list of reportable chemicals is effective January
1 of the calendar year following any of the dates identified in FY2020
NDAA section 7321(c)(1)(A). Accordingly, these nine PFAS are reportable
beginning with the 2025 reporting year (i.e., reports due by July 1,
2026), and EPA is issuing this final rule to amend the EPCRA section
313 list of reportable chemicals in 40 CFR 372.65 to include the nine
non-CBI PFAS added pursuant to the FY2020 NDAA.
Note that pursuant to the rule, entitled ``Changes to Reporting
Requirements for Per- and Polyfluoroalkyl Substances and to Supplier
Notifications for Chemicals of Special Concern; Community Right-to-Know
Toxic Chemical Release Reporting; Final Rule'' (88 FR 74360, October
31, 2023 (FRL-8741-04-OCSPP)), all PFAS added to TRI pursuant to FY2020
NDAA sections 7321(b) and (c), are designated as chemicals of special
concern (40 CFR 372.28), which also applies to the nine PFAS identified
in this rulemaking. Chemicals of special concern are excluded from the
de minimis exemption, may not be reported on a Form A (Alternate
Threshold Certification Statement), and have limits related to
reporting requirements. For more information on the addition of PFAS to
the list of chemicals of special concern, see 40 CFR 372.28.
III. Good Cause Exception
Section 553(b)(B) of the Administrative Procedure Act (APA), 5
U.S.C. 553(b)(B), provides that, when an agency for good cause finds
that public notice and comment procedures are impracticable,
unnecessary, or contrary to the public interest, the agency may issue a
rule without providing notice and an opportunity for public comment.
EPA has determined that there is good cause for making this rule final
without prior proposal and opportunity for comment because such notice
and opportunity for comment is unnecessary. This action is being taken
to comply with a mandate in an Act of Congress, in which Congress
identified actions that automatically add these chemicals to the TRI.
Thus, EPA has no discretion as to the outcome of this rule, which
aligns the regulations with the self-effectuating changes provided by
the FY2020 NDAA.

V. Statutory and Executive Order Reviews
Additional information about these statutes and Executive orders
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.
A. Executive Order 12866: Regulatory Planning and Review and 14094:
Modernizing Regulatory Review
This action is not a significant regulatory action as defined in
Executive Order 12866 (58 FR 51735, October 4, 1993), as amended by
Executive Order 14094 (88 FR 21879, April 11, 2023), and was therefore
not subject to a requirement for Executive Order 12866 review.
B. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA, 44 U.S.C. 3501 et. seq. Burden is defined in 5 CFR
1320.3(b). The Office of Management and Budget (OMB) has previously
approved the information collection activities contained in the
existing regulations and assigned OMB control numbers 2070-0212 and
2050-0078.
Currently, the facilities subject to the reporting requirements
under EPCRA section 313 and PPA section 6607 must use EPA Toxic
Chemicals Release Inventory Form R (EPA Form 9350-1). The nine newly
added PFAS are subject to the same reporting requirements as other
chemicals of special concern and are excluded from certain burden-
reduction reporting options (i.e., the de minimis exemption and the
option to use Form A, range reporting). The Form R must be completed if
a facility manufactures, processes, or otherwise uses any listed
chemical above threshold quantities and meets certain other criteria.
Respondents may designate the specific chemical identity of a
substance as a trade secret pursuant to EPCRA section 322 (42 U.S.C.
11042) and 40 CFR part 350. OMB has approved the reporting and
recordkeeping requirements related to Form R, supplier notification,
and petitions under OMB Control No. 2070-0212 (EPA Information
Collection Request (ICR) No. 2613.04) and those related to trade secret
designations under OMB Control No. 2050-0078 (EPA ICR No. 1428.12).
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 relevant to
EPA's regulations in 40 CFR are listed in 40 CFR part 9 and displayed
on the information collection instruments (e.g., forms, instructions).
C. Regulatory Flexibility Act (RFA)
This action is not subject to the RFA, 5 U.S.C. 601 et seq. The RFA
applies only to rules subject to notice and comment rulemaking
requirements under the APA, 5 U.S.C. 553, or any other statute. As
discussed in Unit III., this rule is not subject to notice and comment
requirements because the Agency has invoked the APA ``good cause''
exception under 5 U.S.C. 553(b).
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate of $100 million
or more as described in UMRA, 2 U.S.C. 1531-1538, and does not
significantly or uniquely affect small governments. The action imposes
no enforceable duty on any State, local, or Tribal governments or the
private sector.
E. Executive Order 13132: Federalism
This action does not have federalism implications, as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999), because it will
not have substantial direct effects on 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.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have Tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000) because it will
not have substantial direct effects on Tribal governments, on the
relationship between the Federal government and the Indian Tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian Tribes. It does not have substantial direct
effects on Tribal governments because EPA does not anticipate that
reporting of the PFAS added to the TRI list in this action will be
conducted by Tribes, so this rulemaking is not expected to impose
substantial direct compliance costs on Tribal governments.
G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it does not concern an environmental health or
safety risk. Since this action does not concern human health, EPA's
2021 Policy on Children's Health also does not apply.
Although this action does not concern an environmental health or
safety risk, this reporting rule will aid in collecting information
regarding PFAS. This rule will be of use in identifying releases of
PFAS to which children may be exposed. EPA believes that the
information obtained as a result of this action could also be used by
the public, government agencies and others to identify potential
problems, set priorities, and take appropriate steps to reduce any
potential human health or environmental risks related to PFAS,
including those that may disproportionately affect children.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use
This action is not a significant energy action as defined in
Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not
likely to have a significant adverse effect on the supply, distribution
or use of energy.
I. National Technology Transfer and Advancement Act (NTTAA)
This rulemaking does not involve technical standards. As such,
NTTAA section 12(d), 15 U.S.C. 272, does not apply to this action.
[[Page 576]]
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations and
Executive Order 14096: Revitalizing Our Nation's Commitment to
Environmental Justice for All
Executive Order 12898 (59 FR 7629, February 16, 1994) directs
Federal agencies, to the greatest extent practicable and permitted by
law, to make environmental justice a part of their mission by
identifying and addressing, as appropriate, disproportionately high and
adverse human health or environmental effects of their programs,
policies, and activities on minority populations (people of color) and
low-income populations.
EPA believes that this type of action does not concern human health
or environmental conditions and therefore cannot be evaluated with
respect to potentially disproportionate and adverse effects on
communities with environmental justice concerns. This action involves
additions to reporting requirements that will not affect the level of
protection provided to human health or the environment.
Although this action does not concern human health or environmental
conditions, EPA may identify and address environmental justice concerns
through information collected under TRI. The information obtained as a
result of this rulemaking will lead to a better understanding of PFAS
releases, which can help inform and tailor future EPA actions regarding
PFAS. For example, EPA may identify and address environmental justice
concerns as a result of the new PFAS information collected under this
rule. The action will also better inform communities living near
facilities that report to TRI, by providing them with information about
PFAS releases and waste management practices occurring in their
communities. Overall, EPA believes that the information obtained as a
result of this action could be used by the public (including people of
color, low-income populations and/or indigenous peoples) to inform
their behavior as it relates to potential exposure to PFAS and by
government agencies and others to identify potential problems, set
priorities, and take appropriate steps to reduce any potential human
health or environmental risks from PFAS.
K. Congressional Review Act (CRA)
This action is subject to the CRA, 5 U.S.C. 801 et seq., and 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).
