Significant New Use Rules on Certain Chemical Substances (23-
3.5e)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is issuing significant new use rules (SNURs) under the 
Toxic Substances Control Act (TSCA) for certain chemical substances 
that were the subject of premanufacture notices (PMNs) and are also 
subject to an Order issued by EPA pursuant to TSCA. The SNURs require 
persons to notify EPA at least 90 days before commencing the 
manufacture (defined by statute to include import) or processing of any 
of these chemical substances for an activity that is designated as a 
significant new use in the SNUR. The required notification initiates 
EPA's evaluation of the conditions of that use for that chemical 
substance. In addition, the manufacture or processing for the 
significant new use may not commence until EPA has conducted a review 
of the required notification; made an appropriate determination 
regarding that notification; and taken such actions as required by that 
determination.

DATES: This rule is effective on August 12, 2025. For purposes of 
judicial review, this rule shall be promulgated at 1 p.m. (EST) on June 
27, 2025.

ADDRESSES: The docket for this action, identified under docket 
identification (ID) number EPA-HQ-OPPT-2023-0328, is available online 
at https://www.regulations.gov or in person at the Office of Pollution 
Prevention and Toxics Docket (OPPT Docket) in the Environmental

SUPPLEMENTARY INFORMATION:

I. Executive Summary

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

    TSCA section 5(a)(2) (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including the factors in TSCA section 5(a)(2).

B. What action is the Agency taking?

    EPA is finalizing SNURs under TSCA section 5(a)(2) for the chemical 
substances identified in this document. These chemical substances were 
the subject of PMNs and are also subject to an Order issued by EPA 
pursuant to TSCA section 5(e)(1)(A), as required by the determinations 
made under TSCA section 5(a)(3)(B). The SNURs identify as significant 
new uses any manufacturing, processing, use, distribution in commerce, 
or disposal that does not conform to the restrictions imposed by the 
underlying TSCA Orders, consistent with TSCA section 5(f)(4). The SNURs 
require persons who intend to manufacture or process any of these 
chemical substances for an activity that is designated as a significant 
new use in the SNURs to notify EPA at least 90 days before commencing 
that activity.
    Previously, EPA proposed SNURs for these chemical substances in the 
Federal Register of June 11, 2024, (89 FR 49770 (FRL-11825-01-OCSPP)). 
The docket includes information considered by the Agency in developing 
the proposed and final rules, including public comments and EPA's 
responses to the comments received as discussed in Unit II.D.

C. Does this action apply to me?

1. General Applicability
    This action applies to you if you manufacture, process, or use the 
chemical substances identified in Unit III of the proposed rule. The 
following list of North American Industrial Classification System 
(NAICS) codes is not intended to be exhaustive, but rather provides a 
guide to help readers determine whether this document applies to them. 
Potentially affected entities may include:
     Manufacturers or processors of one or more subject 
chemical substances (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries.
2. Applicability to Importers and Exporters
    This action may also apply to certain entities through pre-existing 
import certification and export notification requirements under TSCA 
(https://www.epa.gov/tsca-import-export-requirements).
    Chemical importers are subject to TSCA section 13 (15 U.S.C. 2612), 
the requirements in 19 CFR 12.118 through 12.127; 19 CFR 127.28, and 40 
CFR part 707, subpart B. Importers of chemical substances in bulk form, 
as part of a mixture, or as part of an article (if required by rule) 
must certify that the shipment of the chemical substance complies with 
all applicable rules and orders under TSCA, including regulations 
issued under TSCA sections 5, 6, 7 and Title IV.
    Pursuant to 40 CFR 721.20, any persons who export or intend to 
export a chemical substance identified in this document are subject to 
the export notification provisions of TSCA section 12(b) (15 U.S.C. 
2611(b)) and must comply with the export notification requirements in 
40 CFR part 707, subpart D.

D. What are the incremental economic impacts of this action?

    EPA has evaluated the potential costs of establishing SNUN 
reporting requirements for potential manufacturers and processors of 
the chemical substances identified in this document. This analysis, 
which is available in the docket, is briefly summarized here.
1. Estimated Costs for SNUN Submissions
    A SNUR requires that any person who intends to engage in such 
activity in the future must first notify EPA by

[[Page 24978]]

submitting a SNUN. If a SNUN is submitted, costs are an estimated 
$45,000 per SNUN submission for large business submitters and $14,500 
for small business submitters. These estimates include the cost to 
prepare and submit the SNUN (including registration for EPA's Central 
Data Exchange (CDX)), and the payment of a user fee. Businesses that 
submit a SNUN would be subject to either a $37,000 user fee required by 
40 CFR 700.45(c)(2)(ii) and (d), or, if they are a small business as 
defined at 13 CFR 121.201, a reduced user fee of $6,480 (40 CFR 
700.45(c)(1)(ii) and (d)). These estimates reflect the costs and fees 
as they are known at the time of this rulemaking.
2. Estimated Costs for Export Notifications
    EPA has also evaluated the potential costs associated with the pre-
existing export notification requirements under TSCA section 12(b) and 
the implementing regulations at 40 CFR part 707, subpart D. For persons 
exporting a substance that is the subject of a SNUR, a one-time notice 
to EPA must be provided for the first export or intended export to a 
particular country. The total costs of export notification will vary by 
chemical, depending on the number of required notifications (i.e., the 
number of countries to which the chemical is exported). While EPA is 
unable to make any estimate of the likely number of export 
notifications for the chemical substances covered by these SNURs, as 
stated in the accompanying economic analysis, the estimated cost of the 
export notification requirement on a per unit basis is approximately 
$106.

II. Background

A. General Information About SNURS

    Unit II. of the proposed rule provides general information about 
SNURs, and additional information about EPA's new chemical program is 
available at https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca.

B. Applicability of the Significant New Use Designation

    To establish a significant new use, EPA must determine that the use 
is not ongoing. As discussed in Unit II.E. of the proposed rule, EPA 
concluded that the proposed significant new uses were not ongoing. If 
EPA subsequently determines that such a use was ongoing as of the date 
of publication of the proposed rule and did not cease prior to issuance 
of the final rule, EPA will not designate that use as a significant new 
use in the final rule. EPA has no information to suggest that any of 
the significant new uses identified in this rule meet this criterion.
    As discussed in the Federal Register of April 24, 1990 (55 FR 17376 
(FRL-3658-5)), EPA believes that the intent of TSCA section 5(a)(1)(B) 
is best served by designating a use as a significant new use as of the 
date of publication of the proposed rule rather than as of the 
effective date of the final rule. The objective of EPA's approach is to 
ensure that a person cannot impede finalization of a SNUR by initiating 
a significant new use after publication of the proposed rule but before 
the effective date of the final rule. Uses arising after the 
publication of the proposed rule are distinguished from uses that are 
identified in the final rule as having been ongoing on the date of 
publication of the proposed rule. The former would be new uses, the 
latter ongoing uses, except that uses that are identified as ongoing as 
of the publication of the proposed rule would not be considered ongoing 
uses if they have ceased by the date of issuance of a final rule.
    In the unlikely event that before a final rule becomes effective a 
person begins commercial manufacturing (including importing) or 
processing of the chemical substances for a use that is designated as a 
significant new use in that final rule, such a person would have to 
cease any such activity upon the effective date of the final rule. To 
resume their activities, these persons would have to first comply with 
all applicable SNUR notification requirements and wait until all TSCA 
prerequisites for the commencement of manufacture or processing have 
been satisfied.
    Issuance of a SNUR for a chemical substance does not signify that 
the chemical substance is listed on the TSCA Chemical Substance 
Inventory (TSCA Inventory). Guidance on how to determine if a chemical 
substance is on the TSCA Inventory is available on the internet at 
https://www.epa.gov/tsca-inventory.

C. Important Information About SNUN Submissions

1. SNUN Submissions
    SNUNs must be submitted on EPA Form No. 7710-25, generated using e-
PMN software, and submitted to the Agency in accordance with the 
procedures set forth in 40 CFR 720.40 and 721.25. E-PMN software is 
available electronically at https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca.
2. Development and Submission of Information
    EPA recognizes that TSCA section 5 does not require development of 
any particular new information (e.g., generating test data) before 
submission of a SNUN. There is an exception: If a person is required to 
submit information for a chemical substance pursuant to a rule, order 
or consent agreement under TSCA section 4, then TSCA section 5(b)(1)(A) 
requires such information to be submitted to EPA at the time of 
submission of the SNUN.
    In the absence of a rule, TSCA order, or consent agreement under 
TSCA section 4 covering the chemical substance, persons are required 
only to submit information in their possession or control and to 
describe any other information known to or reasonably ascertainable by 
them (see 40 CFR 720.50). However, upon review of PMNs and SNUNs, the 
Agency has the authority to require appropriate testing. To assist with 
EPA's analysis of the SNUN, submitters are encouraged, but not 
required, to provide the potentially useful information as identified 
for the chemical substance in Unit III.C. of the proposed rule.
    EPA strongly encourages persons, before performing any testing, to 
consult with the Agency pertaining to protocol selection. Furthermore, 
pursuant to TSCA section 4(h), which pertains to reduction of testing 
in vertebrate animals, EPA encourages consultation with the Agency on 
the use of alternative test methods and strategies (also called New 
Approach Methodologies, or NAMs), if available, to generate the 
recommended test data. EPA encourages dialog with Agency 
representatives to help determine how best the submitter can meet both 
the data needs and the objective of TSCA section 4(h). For more 
information on alternative test methods and strategies to reduce 
vertebrate animal testing, visit https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce.
    The potentially useful information described in Unit III. of the 
proposed rule may not be the only means of providing information to 
evaluate the chemical substance associated with the significant new 
uses. However, submitting a SNUN without any test data may increase the 
likelihood that EPA will take action under TSCA sections 5(e) or 5(f). 
EPA recommends that potential SNUN submitters contact EPA early enough 
so that they will be able to conduct the appropriate tests.

[[Page 24979]]

    SNUN submitters should be aware that EPA will be better able to 
evaluate SNUNs which provide detailed information about human exposure 
and environmental release that may result from the significant new use 
of the chemical substances.

D. Public Comments on Proposed Rule and EPA Responses

    EPA received public comments on the proposed SNURs and prepared a 
Response to Comment document that provides the Agency responses. The 
comments and the Response to Comment document are available in the 
docket. As described in the Response to Comment document, and in order 
to ensure consistency with the TSCA section 5(e) orders for these 
substances, EPA is finalizing these SNURs with the following changes:
     For PMNs P-21-48 (40 CFR 721.11832); P-21-130 (40 CFR 
721.11833); P-21-131 (40 CFR 721.11834); P-21-177 (40 CFR 721.11835); 
P-21-204 (40 CFR 721.11836); P-22-12 (40 CFR 721.11837); PMN P-21-124 
(721.11845); P-21-180 (40 CFR 721.11849); PMN P-22-55 (721.11856); P-
22-150 (40 CFR 721.11859); P-22-152 (40 CFR 721.11860); P-22-161 (40 
CFR 721.11861); and P-22-177 (40 CFR 721.11862), EPA modified the 
hazard communication requirements by adding a reference to 40 CFR 
721.72(e) and setting the associated de minimis concentration at 1.0%.
     For PMNs P-21-48 (40 CFR 721.11832); P-21-130 (40 CFR 
721.11833); P-21-131 (40 CFR 721.11834); P-21-177 (40 CFR 721.11835); 
P-21-204 (40 CFR 721.11836); P-21-180 (40 CFR 721.11849); and P-22-12 
(40 CFR 721.11837) EPA corrected the timeframe for manufacture to 9 
months rather than 18 months.
    In addition to the changes to respond to comments, EPA identified 
the need to revise the following proposed SNURs:
     For PMN P-22-55 (721.11856), EPA corrected the significant 
new use regarding the manner in which the substance is imported. The 
significant new use now reads ``It is a significant new use to import 
the substance other than in solution, unless in sealed containers 
weighing 5 kilograms or less.''
     For PMN P-21-199 (721.11850), EPA corrected the second 
sentence of paragraph (a)(1) to add the word ``completely'' before 
``reacted or destroyed.''
     For PMN P-21-140 (721.11848), EPA added the requirements 
at 40 CFR 721.80(f) by reference, consistent with the prohibition on 
domestic manufacture in the TSCA section 5(e) order for the substance.

III. Chemical Substances Subject to These SNURs

A. What is the designated cutoff date for ongoing uses?

    EPA designates the date of publication of the proposed rule as the 
cutoff date for determining whether the new use is ongoing, i.e., June 
11, 2024 (89 FR 49770 (FRL-11825-01-OCSPP)). This designation is 
explained in more detail in Unit II.B.

B. What information is provided for each chemical substance?

    In Unit III.C. of the proposed rule, EPA provided the following 
information for each chemical substance subject to these SNURs:
     PMN number (the CFR citation assigned in the regulatory 
text section of this document).
     Chemical name (generic name, if the specific name is 
claimed as CBI).
     Chemical Abstracts Service Registry Number (CASRN) (if 
assigned for confidential chemical identities).
     Basis for the SNUR (e.g., effective date of and basis for 
the TSCA Order).
     Potentially useful information.
    The regulatory text section of this document specifies the 
activities designated as significant new uses. Certain new uses, 
including production volume limits and other uses designated, may be 
claimed as CBI, as discussed in more detail in Unit II.C. of the 
proposed rule.
    In addition, as discussed in Unit III.B. of the proposed rule, 
these SNURs include PMN substances that are subject to orders issued 
under TSCA section 5(e)(1)(A), as required by the determinations made 
under TSCA section 5(a)(3)(B). Those TSCA Orders require protective 
measures to limit exposures or otherwise mitigate the potential 
unreasonable risk. As such, the SNURs identify as significant new uses 
any manufacturing, processing, use, distribution in commerce, or 
disposal that does not conform to the restrictions imposed by the 
underlying TSCA Orders, consistent with TSCA section 5(f)(4).

IV. Statutory and Executive Order Reviews

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

A. Executive Order 12866: Regulatory Planning and Review

    This action establishes SNURs for new chemical substances that were 
the subject of PMNs. The Office of Management and Budget (OMB) has 
exempted these types of actions from review under Executive Order 12866 
(58 FR 51735, October 4, 1993).

B. Executive Order 14192: Unleashing Prosperity Through Deregulation

    Executive Order 14192 (90 FR 9065, February 6, 2025) does not apply 
because a significant new use rule for a new chemical under TSCA 
section 5 are exempted from review under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    According to the PRA (44 U.S.C. 3501 et seq.), an agency may not 
conduct or sponsor, and a person is not required to respond to a 
collection of information that requires OMB approval under PRA, unless 
it has been approved by OMB and displays a currently valid OMB control 
number. The OMB control numbers for EPA's regulations in title 40 of 
the CFR, after appearing in the Federal Register, are listed in 40 CFR 
part 9, and included on the related collection instrument or form, if 
applicable.
    The information collection requirements related to SNURs have 
already been approved by OMB pursuant to PRA under OMB control number 
2070-0038 (EPA ICR No. 1188). This action does not impose any burden 
requiring additional OMB approval. If an entity were to submit a SNUN 
to the Agency, the annual burden is estimated to average between 30 and 
170 hours per submission. This burden estimate includes the time needed 
to review instructions, search existing data sources, gather and 
maintain the data needed, and complete, review, and submit the required 
SNUN.
    The listing of the OMB control numbers of the collection 
instruments and their subsequent codification in the table in 40 CFR 
9.1 satisfies the display requirements of the PRA and OMB's 
implementing regulations at 5 CFR part 1320. Since this ICR was 
previously subject to public notice and comment prior to OMB approval, 
and given the technical nature of the table in 40 CFR part 9, EPA finds 
that further notice and comment to amend it is unnecessary. As a 
result, EPA finds that there is ``good cause'' under section 
553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C. 
553(b)(3)(B)) to amend this table in 40 CFR 9.1 without further notice 
and comment.

[[Page 24980]]

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 (5 
U.S.C. 601 et seq.). The requirement to submit a SNUN applies to any 
person (including small or large entities) who intends to engage in any 
activity described in the final rule as a ``significant new use.'' 
Because these uses are ``new,'' based on all information currently 
available to EPA, EPA has concluded that no small or large entities 
presently engage in such activities.
    A SNUR requires that any person who intends to engage in such 
activity in the future must first notify EPA by submitting a SNUN. 
Although some small entities may decide to pursue a significant new use 
in the future, EPA cannot presently determine how many, if any, there 
may be. However, EPA's experience to date is that, in response to the 
promulgation of SNURs covering over 1,000 chemicals, the Agency 
receives only a small number of notices per year. For example, the 
number of SNUNs received was 7 in Federal fiscal year (FY) 2020, 9 in 
FY2021, 9 in FY2022, 23 in FY2023, and 7 in FY2024, and only a fraction 
of these submissions were from small businesses.
    In addition, the Agency currently offers relief to qualifying small 
businesses by reducing the SNUN submission fee from $37,000 to $6,480. 
This lower fee reduces the total reporting and recordkeeping cost of 
submitting a SNUN to about $14,500 per SNUN submission for qualifying 
small firms. Therefore, the potential economic impacts of complying 
with these proposed SNURs are not expected to be significant or 
adversely impact a substantial number of small entities. In a SNUR that 
published in the Federal Register of June 2, 1997 (62 FR 29684) (FRL-
5597-1), the Agency presented its general determination that SNURs are 
not expected to have a significant economic impact on a substantial 
number of small entities, which was provided to the Chief Counsel for 
Advocacy of the Small Business Administration.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more (in 1995 dollars) in any one year as described in UMRA, 2 U.S.C. 
1531-1538, and does not significantly or uniquely affect small 
governments. Based on EPA's experience with proposing and finalizing 
SNURs, State, local, and Tribal governments have not been impacted by 
SNURs, and EPA does not have any reasons to believe that any State, 
local, or Tribal government will be impacted by these SNURs. In 
addition, the estimated costs of this action to the private sector do 
not exceed $183 million or more in any one year (the 1995 dollars are 
adjusted to 2023 dollars for inflation using the GDP implicit price 
deflator). The estimated costs for this action are discussed in Unit 
I.D.

F. Executive Order 13132: Federalism

    This action will not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999), because it is not 
expected to have a substantial direct effect 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. Accordingly, the requirements of Executive Order 13132 do 
not apply to this action.

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

    This action will not have Tribal implications as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000), because it is 
not expected to have substantial direct effects on Indian Tribes, 
significantly or uniquely affect the communities of Indian Tribal 
governments and does not involve or impose any requirements that affect 
Indian Tribes. Accordingly, the requirements of Executive Order 13175 
do not apply to this action.

H. 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 a human health risk, 
EPA's 2021 Policy on Children's Health also does not apply. Although 
the establishment of these SNURs do not address an existing children's 
environmental health concern because the chemical uses involved are not 
ongoing uses, SNURs require that persons notify EPA at least 90 days 
before commencing manufacture (defined by statute to include import) or 
processing of the identified chemical substances for an activity that 
is designated as a significant new use by the SNUR. This notification 
allows EPA to assess the intended uses to identify potential risks and 
take appropriate actions before the activities commence.

I. 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.

J. National Technology Transfer and Advancement Act (NTTAA)

    This action does not involve any technical standards subject to 
NTTAA section 12(d) (15 U.S.C. 272 note).

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).
