Abstract

EPA is proposing 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 who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. 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.

Significant New Use Rules on Certain Chemical Substances (25-
3.5e)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing 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 who intend to manufacture (defined by statute to include 
import) or process any of these chemical substances for an activity 
that is proposed as a significant new use by this rulemaking to notify 
EPA at least 90 days before commencing that activity. 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.

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) (see 
also the discussion in Unit II.).

B. What action is the Agency taking?

    EPA is proposing SNURs for the chemical substances discussed in 
Unit III. These SNURs, if finalized as proposed, would require persons 
who intend to manufacture or process any of these chemical substances 
for an activity that is designated as a significant new use to notify 
EPA at least 90 days before commencing that activity.

C. Does this action apply to me?

1. General Applicability
    This action applies to you if you manufacture, process, or use the 
chemical substances contained in this 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:
    <bullet> 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 Eexporters
    This action may also apply to certain entities through pre-existing 
import certification and export notification requirements under TSCA 
(<a href="https://www.epa.gov/tsca-import-export-requirements">https://www.epa.gov/tsca-import-export-requirements</a>).
    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 that is the subject of this proposed rule 
on or after July 6, 2026 are subject to 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 (including 
importers) and processors of the chemical substances subject to these 
proposed SNURs. This analysis, which is available in the docket, is 
briefly summarized here.
1. Estimated Costs for SNUN Submissions
    If a SNUN is submitted, costs are an estimated $45,496 per SNUN 
submission for large business submitters and $14,976 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)). The costs of submission for SNUNs will not 
be incurred by any company unless a company decides to pursue a 
significant new use as defined in these SNURs. Additionally, these 
estimates reflect the costs and fees as they are known at the time of 
this rulemaking.
2. Estimated Ccosts for Export Notifications
    EPA has also evaluated the potential costs associated with the 
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

[[Page 34481]]

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.

E. What should I consider as I prepare my comments for EPA?

II. Background

    This unit provides general information about SNURs. For additional 
information about EPA's new chemical program go to <a href="https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca">https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca</a>.

A. Significant New Use Determination Factors

    TSCA section 5(a)(2) states that EPA's determination that a use of 
a chemical substance is a significant new use must be made after 
consideration of all relevant factors, including:
    <bullet> The projected volume of manufacturing and processing of a 
chemical substance.
    <bullet> The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
    <bullet> The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
    <bullet> The reasonably anticipated manner and methods of 
manufacturing, processing, distribution in commerce, and disposal of a 
chemical substance.
    In determining what would constitute a significant new use for the 
chemical substances that are the subject of these SNURs, EPA considered 
relevant information about the toxicity of the chemical substances, and 
potential human exposures and environmental releases that may be 
associated with the substances, in the context of the four bulleted 
TSCA section 5(a)(2) factors listed in this unit and discussed in Unit 
III.
    These proposed 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). The TSCA Orders 
require protective measures to limit exposures or otherwise mitigate 
the potential unreasonable risk. The proposed 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).

B. Rationale and Objectives of the SNURs

1. Rationale
    Under TSCA, no person may manufacture a new chemical substance or 
manufacture or process a chemical substance for a significant new use 
until EPA makes a determination as described in TSCA section 5(a) and 
takes any required action. The issuance of a SNUR is not a risk 
determination itself, only a notification requirement for ``significant 
new uses,'' so that the Agency has the opportunity to review the SNUN 
for the significant new use and make a TSCA section 5(a)(3) risk 
determination.
    During review of the PMNs submitted that are subject to these 
proposed SNURs, EPA concluded that regulation was warranted under TSCA 
section 5(e), pending the development of information sufficient to make 
reasoned evaluations of the health or environmental effects of the 
chemical substances. Based on the findings outlined in Unit III., TSCA 
section 5(e) Orders requiring the use of appropriate exposure controls 
were negotiated with the PMN submitters. As a general matter, EPA 
believes it is necessary to follow the TSCA Orders with a SNUR that 
identifies the absence of those protective measures as significant new 
uses to ensure that all manufacturers and processors--not just the 
original submitter--are held to the same standard.
2. Objectives
    EPA is proposing these SNURs because the Agency has determined it 
is appropriate:
    <bullet> To 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).
    <bullet> To have an opportunity to review and evaluate data 
submitted in a SNUN before the submitter begins manufacturing or 
processing a listed chemical substance for the described significant 
new use.
    <bullet> To be obligated to make a determination under TSCA section 
5(a)(3) regarding the use described in the SNUN, under the conditions 
of use. The Agency will either determine under TSCA section 5(a)(3)(C) 
that the significant new use is not likely to present an unreasonable 
risk, including an unreasonable risk to a potentially exposed or 
susceptible subpopulation identified as relevant by the Administrator 
under the conditions of use, or make a determination under TSCA section 
5(a)(3)(A) or (B) and take the required regulatory action associated 
with the determination, before manufacture or processing for the 
significant new use of the chemical substance can occur.
    Issuance of a proposed 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 at https://
www.epa.gov/tsca-inventory.

C. Significant New Uses Claimed as CBI

    EPA is proposing to establish certain significant new uses which 
have been claimed as CBI subject to Agency confidentiality regulations 
at 40 CFR parts 2 and 703. Absent a final determination or other 
disposition of the confidentiality claim under these regulations, EPA 
is required to keep this information confidential. EPA promulgated a 
procedure at 40 CFR 721.11 to deal with the situation where a specific 
significant new use is CBI. Under these procedures, a manufacturer or 
processor may ask EPA to identify the confidential significant new use 
subject to the SNUR. The manufacturer or processor must show that it 
has a bona fide intent to manufacture or process the chemical 
substance. If EPA concludes that the person has shown a bona fide 
intent to manufacture or process the chemical substance, EPA will 
identify the confidential significant new use to that person. Since 
most of the chemical identities of the chemical substances subject to 
these SNURs are also CBI, manufacturers and processors can combine the 
bona fide submission under the procedure in 40 CFR 721.11 into a single 
step.

[[Page 34482]]

D. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to SNURs, recordkeeping 
requirements, exemptions to reporting requirements, and applicability 
of the rule to uses occurring before the effective date of the rule. 
Pursuant to 40 CFR 721.1(c), persons subject to SNURs must comply with 
the same requirements and EPA regulatory procedures as submitters of 
PMNs under TSCA section 5(a)(1)(A). In particular, these requirements 
include the information submission requirements of TSCA sections 5(b) 
and 5(d)(1), the exemptions authorized by TSCA sections 5(h)(1), (2), 
(3), and (5) and the regulations at 40 CFR part 720. In addition, 
provisions relating to user fees appear at 40 CFR part 700.
    Once EPA receives a SNUN, EPA must either determine that the 
significant new use is not likely to present an unreasonable risk of 
injury under the conditions of use for the chemical substance or take 
such regulatory action as is associated with an alternative 
determination under TSCA section 5 before the manufacture (including 
import) or processing for the significant new use can commence. If EPA 
determines that the significant new use of the chemical substance is 
not likely to present an unreasonable risk, EPA is required under TSCA 
section 5(g) to make public, and submit for publication in the Federal 
Register, a statement of EPA's findings.
    As discussed in Unit I.C.2., persons who export or intend to export 
a chemical substance identified in a proposed or final SNUR are subject 
to the export notification provisions of TSCA section 12(b), and 
persons who import a chemical substance identified in a final SNUR are 
subject to the TSCA section 13 import certification requirements. See 
also <a href="https://www.epa.gov/tsca-import-export-requirements">https://www.epa.gov/tsca-import-export-requirements</a>.

E. Applicability of the Proposed SNURs to Uses Occurring Before the 
Effective Date of the Final Rule

    To establish a significant new use, EPA must determine that the use 
is not ongoing. The chemical substances subject to this proposed rule 
have undergone premanufacture review and received determinations under 
TSCA section 5(a)(3)(C). TSCA Orders have been issued for these 
chemical substances and the PMN submitters are required by the TSCA 
Orders to submit a SNUN before undertaking activities that would be 
designated as significant new uses in these SNURs. Additionally, the 
identities of many of the chemical substances subject to this proposed 
rule have been claimed as confidential per 40 CFR 720.85, further 
reducing the likelihood that another party would manufacture or process 
the substances for an activity that would be designated as a 
significant new use. Based on this, the Agency believes that it is 
highly unlikely that any of the significant new uses identified in Unit 
III. are ongoing.
    When the chemical substances identified in Unit III. are added to 
the TSCA Inventory, EPA recognizes that, before the rule is effective, 
other persons might engage in a use that has been identified as a 
significant new use. Persons who begin manufacture or processing of the 
chemical substances for a significant new use identified on or after 
the designated cutoff date specified in Unit III.A. 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 EPA would have to take 
action under TSCA section 5 allowing manufacture or processing to 
proceed.

F. 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 <a href="https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca">https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca</a>.
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.
    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 <a href="https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce">https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce</a>.
    The potentially useful information described in Unit III. 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.
    SNUN submitters should be aware that EPA will be better able to 
evaluate SNUNs that provide detailed information about human exposure 
and environmental release that may result from the significant new use 
of the chemical substances.

III. Chemical Substances Subject to These Proposed SNURs

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

    EPA designates June 5, 2026 as the cutoff date for determining 
whether the new use is ongoing. This designation is explained in more 
detail in Unit II.E.

B. What information is provided for each chemical substance?

    For each chemical substance identified in Unit III.C., EPA provides 
the following information:
    <bullet> PMN number (the proposed CFR citation assigned in the 
regulatory text section of the proposed rule).

[[Page 34483]]

    <bullet> Chemical name (generic name, if the specific name is 
claimed as CBI).
    <bullet> Chemical Abstracts Service Registry Number (CASRN) or 
Accession Number (if assigned for confidential chemical identities).
    <bullet> Basis for the SNUR (e.g., effective date of and basis for 
the TSCA Order).
    <bullet> Potentially useful information.
    The regulatory text section of the proposed rule specifies the 
activities designated as significant new uses. Certain new uses, 
including production volume limits and other uses designated in the 
proposed rules, may be claimed as CBI.
    These proposed 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. The proposed 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).
    Where EPA determined that the PMN substance may present an 
unreasonable risk of injury to human health via inhalation exposure, 
the underlying TSCA Order usually requires that potentially exposed 
employees wear specified respirators unless actual measurements of the 
workplace air show that air-borne concentrations of the PMN substance 
are below a New Chemical Exposure Limit (NCEL). The comprehensive NCELs 
provisions in TSCA Orders include requirements addressing performance 
criteria for sampling and analytical methods, periodic monitoring, 
respiratory protection, and recordkeeping. No comparable NCEL 
provisions currently exist for SNURs in 40 CFR part 721, subpart B. 
Therefore, for these cases, the individual SNURs in 40 CFR part 721, 
subpart E, will state that persons subject to the SNUR who wish to 
pursue NCELs as an alternative to the 40 CFR 721.63 respirator 
requirements may request to do so under 40 CFR 721.30. EPA expects that 
persons whose 40 CFR 721.30 requests to use the NCELs approach for 
SNURs that are approved by EPA will be required to comply with NCELs 
provisions that are comparable to those contained in the corresponding 
TSCA Order.

C. Which chemical substances are subject to these proposed SNURs?

    The substances subject to the proposed SNURs in this document are 
as follows, listed by PMN number and with the proposed CFR citation:
P-21-76 (40 CFR 721.12225)
    Chemical Name: Alcohols, C16-18 and C18-unsatd., reaction products 
with substituted alkyloxirane and alkyl acid (generic).
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: August 26, 2025.
    Basis for TSCA Order: The PMN states that the use will be as an 
additive for fluids used in oil drilling operations. Based on submitted 
test data on the PMN substance, EPA has identified concerns for skin 
sensitization and systemic effects. The Order was issued under TSCA 
sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding 
that in the absence of sufficient information to permit a reasoned 
evaluation, the substance may present an unreasonable risk of injury to 
human health. To protect against these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> No manufacture, processing, or use of the PMN substance in 
any manner that results in inhalation exposure;
    <bullet> No use of the PMN substance in a consumer product; and
    <bullet> Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
systemic toxicity testing may be potentially useful to characterize the 
health effects of the PMN substance. Although the Order does not 
require these tests, the Order's restrictions remain in effect until 
the Order is modified or revoked by EPA based on submission of this or 
other relevant information.
P-22-40 (40 CFR 721.12226)
    Chemical Name: Manganate(4-), hexakis(cyano-.kappa.C)-, 
manganese(2+) sodium, (OC-6-11)-.
    CASRN: 2073840-04-5.
    Effective Date of TSCA Order: August 25, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as a component used in manufacture of high-
performance batteries. Based on comparison to analogous chemical 
substances and information for other poorly soluble respirable 
particles, EPA has identified concerns for lung effects (lung 
overload). Based on comparison to analogous chemical substances and 
components of the PMN substance, EPA has also identified concerns for 
acute toxicity, skin sensitization, and reproductive and systemic 
effects. Based on submitted test data on the PMN substance and 
comparison to analogous chemical substances, EPA predicts toxicity to 
aquatic organisms may occur at concentrations that exceed 0.2 ppb. The 
Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 
5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient 
information to permit a reasoned evaluation, the substance may present 
an unreasonable risk of injury to human health and the environment. To 
protect against these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Use of a NIOSH-certified respirator with an APF of at 
least 1000 where there is a potential for inhalation exposure;
    <bullet> Manufacturing and processing of the PMN substance only in 
an enclosed process. The process remains enclosed as long as the only 
releases are from sampling, dust filter changes, loss of integrity, or 
failure of the manufacturing process equipment or control systems;
    <bullet> Dust filter changes may be performed no more than two 
times a year;
    <bullet> At each site that the PMN substance is manufactured that 
has off-gas waste streams, all such waste streams must be captured and 
routed through engineering controls that achieve a total combined 
efficiency of 99.9% destruction of the PMN substance;
    <bullet> Manufacture of the PMN substance only if the concentration 
of manganese does not exceed the confidential percentage by weight 
listed in the Order;
    <bullet> No use of the PMN substance in any manner that results in 
inhalation exposure to workers;
    <bullet> Use of the PMN substance only as a component in 
manufacture of high performance batteries;
    <bullet> When the PMN substance is in solid form the PMN substance 
may be disposed of by landfill. Landfill disposal

[[Page 34484]]

of the PMN substance must be at a hazardous waste landfill facility 
that is in compliance with RCRA subtitle C and D. Otherwise the PMN 
substance, or waste streams containing the PMN substance, must be 
disposed of by incineration. Disposal of the PMN substance by 
incineration must not exceed the confidential annual limit listed in 
the Order however the limit does not apply to quantities sent for 
incineration at a hazardous waste incineration facility that is 
compliant with RCRA subtitle C;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 0.2 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
specific target organ toxicity, pulmonary effects, reproductive 
toxicity, neurotoxicity, and aquatic toxicity testing may be 
potentially useful to characterize the health and environmental effects 
of the PMN substance. Although the Order does not require these tests, 
the Order's restrictions remain in effect until the Order is modified 
or revoked by EPA based on submission of this or other relevant 
information.

streams containing the PMN substance, must be disposed of by 
incineration. Disposal of the PMN substance by incineration must not 
exceed the confidential annual limit listed in the Order however the 
limit does not apply to quantities sent for incineration at a hazardous 
waste incineration facility that is compliant with RCRA subtitle C;
    <bullet> No release of the PMN substance, or any waste stream

    Effective Date of TSCA Order: June 18, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as an additive used in consumer, commercial, 
and industrial applications. Based on submitted test data on the PMN 
substances, EPA predicts toxicity to aquatic organisms may occur at 
concentrations that exceed 18 ppb. The Order was issued under TSCA 
sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding 
that in the absence of sufficient information to permit a reasoned 
evaluation, the substances may present an unreasonable risk of injury 
to the environment. To protect against these risks, the Order requires:
    <bullet> No processing for use or use of the PMN substances in a 
consumer product unless the concentration of the PMN substances 
combined does not exceed 1.7% by weight in the consumer product;
    <bullet> No release of the PMN substances, or any waste stream 
containing the PMN substances, resulting in surface water 
concentrations that exceed 18 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label

    Chemical Name: Multi-walled carbon nanotubes.
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: July 7, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as an additive used in battery manufacture. 
Based on comparison to analogous chemical substances, EPA has 
identified concerns for lung and systemic effects, lung 
carcinogenicity, genetic toxicity, and eye and respiratory irritation. 
Due to insufficient information, EPA was unable to estimate the 
environmental hazard of the PMN substance. The Order was issued under 
TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a 
finding that in the absence of sufficient information to permit a 
reasoned evaluation, the substance may present an unreasonable risk of 
injury to human health and the environment. To protect against these 
risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Personal breathing zone (PBZ) exposure monitoring in 
accordance with the procedures and conditions described in the Order;
    <bullet> The order requires exposure monitoring. Before the 
required exposure monitoring occurs where there is a potential for 
inhalation exposure: (1) use of a NIOSH-certified respirator with an 
APF of at least 50 is required at the confidential site listed in the 
Order, (2) use of a NIOSH-certified respirator with an APF of 50 is 
required at sites where batteries or the other confidential items 
listed in the Order containing the PMN substance are only recycled. or 
(3) use of a NIOSH-certified respirator with an APF of at least 1,000 
is required at all other sites.
    After the required exposure monitoring occurs: (1) compliance with 
a NCEL of 8.97E-05 mg/m\3\ as an 8-hour time-weighted average, or use 
of a NIOSH-certified respirator with an APF in accordance with Table 2 
in the Order (which lists required respiratory protection/action 
corresponding to different exposures) is required, (2) use of a NIOSH-
certified respirator with an APF of 50 is permitted at sites where 
batteries or the other confidential items listed in the Order 
containing the PMN substance are only recycled.
    <bullet> Manufacture of the PMN substance only by import into the 
United States (i.e., no domestic manufacture);
    <bullet> Processing of the PMN substance only with the use of 
engineering controls with an overall minimum efficiency of 94%;
    <bullet> Processing for use and use of the PMN substance in the 
final battery only if the concentration of the PMN substance does not 
exceed the confidential concentration listed in the Order;
    <bullet> Use of the PMN substance only as an additive used in 
battery manufacture;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, to water; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be

P-22-187 and P-24-88 (40 CFR 721.12230)
    Chemical Name: Mixed metal oxide (generic) (P-22-187 and P-24-88).
    Accession No.: 303027.
    Effective Date of TSCA Orders: November 30, 2023 (P-22-187) and 
October 4, 2024 (P-24-88).
    Basis for action: PMN P-22-187 states that the generic (non-
confidential) use will be as a substance for use in the manufacture of 
battery components. Based on test data on the PMN substance, EPA 
identified concerns for developmental effects. Based on comparison to 
analogous respirable, poorly soluble particulates, EPA also identified 
concerns for lung effects (including lung overload). EPA issued an 
Order under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substance may present an unreasonable 
risk of injury to human health. To protect against these risks, the 
Order for PMN P-22-187 required:
    <bullet> Use of a NIOSH-certified particulate respirator with an 
APF of at least 1000 where there is a potential for inhalation 
exposure;
    <bullet> Manufacture of the PMN substance only by import into the 
United States (i.e., no domestic manufacture) with <10% respirable 
particles (i.e., particle size <=10 microns);

[[Page 34486]]

    <bullet> Manufacture, processing, and use of the PMN substance only 
when using dust controls with a capture and control efficiency of >97% 
when the PMN substance is in solid form;
    <bullet> Processing for use and use of the PMN substance only for 
the confidential use listed in the Order;
    <bullet> Disposal of the PMN substance and waste streams containing 
the PMN substance only by landfill or using hazardous waste 
incineration with >99.9% removal efficiency;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure; and
    <bullet> Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS.
    On July 31, 2025, the submitter of PMN P-22-187. requested a 
modification of their Order to allow the use of a NIOSH-certified 
particulate respirator with an APF of at 10 to replace the then 
currently required respirator with an APF of 1000. EPA performed a risk 
assessment based on the new intended conditions of use, subsequently 
modified the terms of the Order to mitigate any unreasonable risks to 
human health and the environment, and issued a modified Order, 
effective September 17, 2025. To protect against these risks, the 
modified Order requires:
    <bullet> Use of a NIOSH-certified particulate respirator with an 
APF of at least 10 where there is a potential for inhalation exposure;
    <bullet> Manufacture of the PMN substance only by import into the 
United States (i.e., no domestic manufacture) with <10% respirable 
particles (i.e., particle size <=10 microns);
    <bullet> Manufacture, processing, and use of the PMN substance only 
when using dust controls with a capture and control efficiency of >97% 
when the PMN substance is in solid form;
    <bullet> Processing for use and use of the PMN substance only for 
the confidential use listed in the Order;
    <bullet> Disposal of the PMN substance and waste streams containing 
the PMN substance only by landfill or using hazardous waste 
incineration with >99.9% removal efficiency;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure; and
    <bullet> Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS.
    On February 26, 2024, EPA received a second PMN, P-24-88, for the 
same substance due to the fact that PMN P-22-187 had not been commenced 
and the substance had not been added to the TSCA Inventory. PMN P-24-88 
states that the generic (non-confidential) use will be in the 
manufacture of battery components. Based on comparison to analogous 
respirable, poorly soluble particulates, EPA has identified concerns 
for lung effects and lung cancer. The Order was issued under TSCA 
sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding 
that in the absence of sufficient information to permit a reasoned 
evaluation, the substance may present an unreasonable risk of injury to 
human health. To protect against these risks, the Order for PMN P-24-88 
requires:
    <bullet> Manufacture, processing, or use of the PMN substance in 
solid form only when using dust controls with a capture and control 
efficiency of at least >97%;
    <bullet> Use of a NIOSH-certified respirator with an APF of at 
least 10 where there is a potential for inhalation exposure;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure; and
    <bullet> Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures including engineering controls.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
carcinogenicity and pulmonary effects testing may be potentially useful 
to characterize the health effects of the PMN(s) substance. Although 
the Order does not require these tests, the Order's restrictions remain 
in effect until the Order is modified or revoked by EPA based on 
submission of this or other relevant information. The proposed SNUR 
would designate as a ``significant new use'' the absence of these 
protective measures.

glycerol.
    CASRN: 2888640-13-7.
    Effective Date of TSCA Order: May 19, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as an additive for the packaging industry. 
Based on comparison to analogous chemical substances, EPA has 
identified concerns for skin sensitization and eye irritation. Based on 
comparison to analogous esters, EPA predicts toxicity to aquatic 
organisms may occur at concentrations that exceed 330 ppb. The Order 
was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substance may present an unreasonable 
risk of injury to human health and the environment. To protect against 
these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> No processing for use or use of the PMN substance in a 
consumer product;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 330 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of eye 
irritation, skin irritation, and aquatic toxicity testing may be 
potentially useful to characterize the health and environmental effects 
of the PMN substance. Although the Order does not require these tests, 
the Order's restrictions remain in effect until the Order is modified

listed in the Order;
    <bullet> Manufacture of the PMN substance only below the 
confidential annual production volume listed in the Order;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, to water; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label

    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
carcinogenicity, eye irritation, specific target organ toxicity, 
pulmonary effects, and aquatic toxicity testing may be potentially 
useful to characterize the health and environmental effects of the PMN 
substance. Although the Order does not require these tests, the Order's 
restrictions remain in effect until the Order is modified or revoked by 
EPA based on submission of this or other relevant information.

    Chemical Name: Polysubstitutedcarbocycle, polyhydroxy, polyalkyl 
(generic).
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: May 28, 2025.
    Basis for TSCA Order: The PMN states that the use will be as an 
additive (e.g., detergent, cleaning agent, dispersant, chelating agent, 
sequestering agent) used in laundry products (e.g., pods, liquids). 
Based on submitted test data on the PMN substance, EPA has identified 
concerns for skin sensitization and GI and systemic effects. Based on 
OECD Toolbox, EPA has also identified concerns for respiratory 
sensitization. Based on submitted test data on the PMN substance, EPA 
predicts toxicity to aquatic organisms may occur at concentrations that 
exceed 19 ppb. The Order was issued under TSCA sections 
5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the 
absence of sufficient information to permit a reasoned evaluation, the 
substance may present an unreasonable risk of injury to human health 
and the environment. To protect against these risks, the Order 
requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Use of a NIOSH-certified respirator with an APF of at 
least 50, or 1000 if spray applied, where there is a potential for 
inhalation exposure;
    <bullet> Manufacture of the PMN substance only by import into the 
United States (i.e., no domestic manufacture);
    <bullet> No processing for use or use of the PMN substance in a 
consumer product where the concentration of the PMN substance is equal 
to or exceeds the confidential percentage in formulation listed in the 
Order;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 19 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.

    Effective Date of TSCA Order: July 31, 2025.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) uses will be as additives in paving applications. Based 
on comparison to analogous chemical substances, EPA has identified 
concerns for corrosion to the eyes, skin and respiratory tract, skin 
sensitization, portal-of-entry (GI) and systemic effects, and 
identified lung toxicity based on structure and intended use. Based on 
comparison to analogous aliphatic amines, EPA predicts toxicity to 
aquatic organisms may occur at concentrations that exceed 0.4 ppb (P-
24-54), 0.1 ppb (P-24-55), and 1 ppb (P-24-56). The Order was issued 
under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a

    CASRNs or Accession Nos.: Not available.
    Effective Date of TSCA Order: July 31, 2025.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) uses will be as additives in paving applications. Based 
on dispersible water solubility, structure, and repeated amine 
moieties, EPA has identified concerns for lung effects (surfactancy and 
cationic binding). Based on pH and comparison to analogous chemical 
substances, EPA has also identified concerns for skin corrosion and 
serious eye damage. Based on comparison to analogous chemical 
substances, EPA has also identified concerns for acute toxicity, skin 
sensitization, portal-of-entry effects, and systemic effects. Based on 
comparison to analogous polycationic polymers, EPA predicts toxicity to 
aquatic organisms may occur at concentrations that exceed 0.7 ppb for 
the P-24-58 substance. Based on comparison to analogous aliphatic 
amines, EPA predicts toxicity to aquatic organisms may occur at 
concentrations that exceed 3.5 ppb for the P-24-59 substance. The Order 
was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substances may present an

    CASRNs or Accession Nos.: Not available.
    Effective Date of TSCA Order: June 27, 2025.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) use of the PMN substances will be for contained uses for 
microlithography for electronic device manufacture. Based on the 
physical/chemical properties of the PMN substances (as described in the 
New Chemical Program's PBT category at 64 FR 60194; November 1999) and 
in the absence of data, the anion and cation of the P-24-98 substance, 
the cations of the P-25-60 and P-25-64 substances, and the cation 
photodegradation products of the P-24-98, P-25-60, and P-25-64 
substances are potentially persistent, bioaccumulative, and toxic (PBT) 
chemicals. EPA estimates that the anion and cation of the P-24-98 
substance and the cations of the P-25-60 and P-25-64 substances will 
persist in the environment for more than six months and that their 
potential to bioaccumulate is unknown. EPA estimates that the cation 
photodegradation products of the P-24-98, P-25-60, and P-25-64 
substances will persist in the environment for more than six months and 
estimates a bioaccumulation factor of greater than or equal to 5,000. 
Based on comparison to analogous chemical substances, EPA has 
identified concerns for acute toxicity, irritation to the skin and 
respiratory tract, eye corrosion, and neurological and systemic effects 
for the cations of the P-24-98, P-25-60, and P-25-64 substances. Based 
on photoreactivity, EPA has also identified concerns for 
photosensitization for the P-24-98, P-25-60, and P-25-64 substances. 
Based on the point of departure value, EPA has also identified concerns 
for local, neurological, developmental, and systemic effects for a 
representative incineration product of the P-24-98 substance. Based on 
comparison to analogous chemical substances, EPA has also identified 
concerns for genetic toxicity for the P-24-98, P-25-60, and P-25-64 
substances. Due to insufficient information, EPA was unable to estimate 
the environmental hazard of the PMN substances. The Order was issued 
under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a 
finding that in the absence of sufficient information to permit a 
reasoned evaluation, the substances may present an unreasonable risk of 
injury to human health or the environment. To protect against these 
risks, the Order requires:
    <bullet> No manufacture of the PMN substances beyond the time 
limits specified in the Order without submittal to EPA the results of 
certain testing described in the Testing section of the Order;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS;
    <bullet> No processing of the PMN substances in any way that 
generates vapor, dust, mist, or aerosol in a non-enclosed process;
    <bullet> Use of the PMN substances only for the confidential use 
listed in the Order;
    <bullet> No domestic manufacture of the PMN substances (i.e., 
import only);
    <bullet> Import of the PMN substance only in solution unless in 
sealed containers weighing 5 kilograms or less; and
    <bullet> No exceedance of the confidential annual importation 
volume listed the Order.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information about the physical/chemical properties, fate, 
bioaccumulation, environmental hazard, and human health effects of the 
PMN substances may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. The submitter has agreed not to exceed the 
time limits specified in the Order without performing the required Tier 
I and Tier II testing outlined in the Testing section of the Order.
P-24-109 (40 CFR 721.12244)
    Chemical Name: Lithium dihalo (oxalato)borate(1-) (generic).
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: August 11, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as an electrolyte salt. Based on comparison 
to analogous chemical substances and submitted test data on the PMN 
substance, EPA has identified concerns for acute toxicity, skin 
irritation, eye corrosion, respiratory irritation, skin sensitization, 
systemic and developmental effects, and

[[Page 34490]]

neurotoxicity. Based on comparison to analogous boron compounds and 
submitted test data on the PMN substance, EPA predicts toxicity to 
aquatic organisms may occur at concentrations that exceed 1 ppb. The 
Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 
5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient 
information to permit a reasoned evaluation, the substance may present 
an unreasonable risk of injury to human health and the environment. To 
protect against these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> No processing for use or use of the PMN substance in a 
consumer product;
    <bullet> No manufacture, processing, or use of the PMN substance in 
any manner that results in inhalation exposure to the PMN substance;
    <bullet> Manufacture, processing, and use of the PMN substance only 
in a liquid solution;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 1 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    EPA has concluded, based on information available to the Agency, 
that use in the absence of several of these protective measures is 
ongoing. Thus, use in the absence of those protective measures cannot 
be designated as significant new uses. Therefore, EPA proposes to 
designate as a significant new use:
    <bullet> Use without a NIOSH-certified respirator with an APF of at 
least 10 where there is a potential for inhalation exposure;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Use without establishment of a hazard communication 
program, including human health and environmental precautionary 
statements on each label and in the SDS.
    <bullet> Use of the PMN substance in a consumer product; and
    <bullet> Release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 1 ppb.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
specific target organ toxicity, reproductive toxicity, developmental 
toxicity, neurotoxicity, and skin sensitization testing may be 
potentially useful to characterize the health effects of the PMN 
substance. Although the Order does not require these tests, the Order's 
restrictions remain in effect until the Order is modified or revoked by 
EPA based on submission of this or other relevant information.

    Effective Date of TSCA Order: August 6, 2025.
    Basis for TSCA Order: The PMN states that the use will be as a 
rubber accelerator for the manufacture of rubber articles. Based on 
submitted test data on the PMN substance, EPA has identified concerns 
for acute toxicity, skin sensitization, and systemic effects. Based on 
test data on hydrolysis products, EPA has also identified concerns for 
acute toxicity, systemic effects, neurotoxicity, and reproductive and 
developmental effects. Based on comparison to analogous 
dithiocarbamates and submitted test data on the PMN substance, EPA 
predicts toxicity to aquatic organisms may occur at concentrations that 
exceed 0.6 ppb. The Order was issued under TSCA sections 
5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the 
absence of sufficient information to permit a reasoned evaluation, the 
substance may present an unreasonable risk of injury to human health or 
the environment. To protect against these risks, the Order requires:
    <bullet> No processing for use or use of the PMN substance in a 
consumer product;
    <bullet> Use of a NIOSH-certified respirator with an APF of at 
least 10 where there is a potential for inhalation exposure;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Manufacture of the PMN substance only by import in a 
pellet form into the United States (i.e., no domestic manufacture);
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, to water; and
    <bullet> Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of acute 
toxicity, skin sensitization, neurotoxicity, reproductive toxicity, 
developmental toxicity, specific target organ toxicity, and aquatic 
toxicity testing may be potentially useful to characterize the health

    Effective Date of TSCA Order: July 18, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as display materials. Based on comparison to 
analogous chemical substances, EPA has identified concerns for systemic 
effects. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 
5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient 
information to permit a reasoned evaluation, the substance may present

    Effective Date of TSCA Order: July 18, 2025.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) uses will be as display materials. Based on the physical/
chemical properties of the PMN substances (as described in the New 
Chemical Program's PBT category at 64 FR 60194; November 1999) and in 
the absence of data, the PMN substances are potentially persistent, 
bioaccumulative, and toxic (PBT) chemicals. EPA estimates that the PMN 
substances will persist in the environment for more than six months and 
estimates a bioaccumulation factor of greater than or equal to 5,000. 
Based on test data for P-24-149 and physical/chemical properties of the 
other substances, EPA has identified concerns for systemic and 
reproductive effects. The Order was issued under TSCA sections 
5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the 
absence of sufficient information to permit a reasoned evaluation, the 
substances may present an unreasonable risk of injury to human health. 
To protect against these risks, the Order requires:
    <bullet> No manufacture, processing, or use of the PMN substances 
in any manner that generates a vapor, mist, dust, or aerosol containing 
the PMN substances;
    <bullet> No processing for use or use of the PMN substances in a

    <bullet> No use of the PMN substances other than for the 
confidential use listed in the Order;
    <bullet> When the PMN substances, or waste streams containing the 
PMN substances, are disposed of by incineration, hazardous waste 
incineration in compliance with RCRA subtitle C, incineration above 
1,000 degrees C for at least two seconds must be used;
    <bullet> No release of the PMN substances, or any waste stream 
containing the PMN substances, to water;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the

(40 CFR 721.12253)
    Chemical Names: Phenyl carboxylic acid, alkylcycloalkyl, 
phenylalkanediyl ester (generic) (P-24-152), Fluoro substituted

polyfluoro-alkyl- (generic) (P-;24-154).
    CASRNs or Accession Nos.: Not available.
    Effective Date of TSCA Order: July 18, 2025.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) uses will be as display materials. Based on the physical/
chemical properties of the PMN substances (as described in the New 
Chemical Program's PBT category at 64 FR 60194; November 1999) and in 
the absence of data, the P-24-153 and P-24-154 PMN substances are 
potentially persistent, bioaccumulative, and toxic (PBT) chemicals. EPA 
estimates that the P-24-153 and P-24-154 PMN substances will persist in 
the environment for more than six months and estimates a 
bioaccumulation factor of greater than or equal to 5,000. Based on 
comparison to analogous chemical substances, EPA has identified 
concerns for systemic effects for P-24-152, P-24-153, and P-24-154. 
Based on comparison to analogous chemical substances, EPA has also 
identified concerns for reproductive effects for P-24-153. Based on 
submitted test data on the P-24-154 PMN substance and comparison to 
analogous neutral organics, EPA predicts toxicity to aquatic organisms 
may occur at concentrations that exceed 0.5 ppb for P-24-154. The Order 
was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substances may present an 
unreasonable risk of injury to human health and the environment. To 
protect against these risks, the Order requires:
    <bullet> No manufacture, processing, or use of the PMN substances 
in any manner that generates a vapor, mist, dust, or aerosol containing 
the PMN substances;
    <bullet> No processing for use or use of the PMN substances in a 
consumer product;
    <bullet> No use of the PMN substances other than for the 
confidential use listed in the Order;
    <bullet> Disposal of the PMN substances by hazardous waste landfill 
only at a facility that is in compliance with Resource Conservation and 
Recovery Act (RCRA) Subtitle C;
    <bullet> Disposal of the P-24-153 and P-24-154 PMN substances, or 
waste streams containing the P-24-153 and P-24-154 PMN substances, by 
incineration only when hazardous waste incineration in compliance with 
RCRA Subtitle C, incineration above 1,000 degrees C for at least two 
seconds is used;
    <bullet> No release of the PMN substances, or any waste stream 
containing the PMN substances, to water;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will

[[Page 34492]]

be designated by this SNUR. EPA has determined that the results of 
toxicokinetics and specific target organ toxicity testing on the P-24-
152 PMN substance, bioaccumulation, reproductive toxicity, specific 
target organ toxicity, and aquatic toxicity testing on the P-24-153 PMN 
substance, and bioaccumulation and chronic aquatic toxicity testing on 
the P-24-154 PMN substance may be potentially useful to characterize 
the fate, health, and environmental effects of the PMN substances. 
Although the Order does not require these tests, the Order's 
restrictions remain in effect until the Order is modified or revoked by 
EPA based on submission of this or other relevant information.
P-24-163 (40 CFR 721.12254)
    Chemical Name: Transition metal polykis (heteroatom substituted 
carbomonocycle), hydroxy- oxo- (generic).
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: August 5, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be in gas adsorption cartridges and protective 
garments. Based on structure and physical/chemical properties of the 
PMN substance, EPA has identified concerns for lung effects (lung 
overload). The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) 
and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of 
sufficient information to permit a reasoned evaluation, the substance 
may present an unreasonable risk of injury to human health. To protect 
against these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Use of a NIOSH-certified respirator with an APF of at 
least 1000 when the proportion of the PMN substance with a particle 
size less than 10 microns is >0.1% by weight where there is a potential 
for inhalation exposure. When the proportion of the PMN substance with 
a particle size less than 10 microns is <=0.1% (by weight), there are 
no inhalation risks, and therefore the worker respirator requirement 
does not apply;
    <bullet> Use of the PMN substance only for the confidential use 
listed in the Order; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. EPA has determined that the results of 
pulmonary effects testing may be potentially useful to characterize the 
health effects of the PMN substance. Although the Order does not 
require these tests, the Order's restrictions remain in effect until 
the Order is modified or revoked by EPA based on submission of this or 
other relevant information.

    Chemical Name: Heteromonocyclealkanol, homopolymer, monoalkyl ether 
(generic).
    CASRN or Accession No.: Not available.
    Effective Date of TSCA Order: August 29, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as a component of a cleaner. Based on 
structure, EPA has identified concerns for pulmonary effects. Based on 
comparison to analogous chemical substances, EPA has also identified 
concerns for skin irritation and systemic effects. Based on comparison 
to analogous nonionic surfactants, EPA predicts toxicity to aquatic 
organisms may occur at concentrations that exceed 140 ppb. The Order 
was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substance may present an unreasonable 
risk of injury to human health and the environment. To protect against 
these risks, the Order requires:
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Manufacture, processing, and use of the PMN substance only 
in a manner that does not result in inhalation exposure to the PMN 
substance;
    <bullet> Processing for use and use of the PMN substance only for 
the confidential use listed in the Order;
    <bullet> No disposal of the PMN substance, or any waste stream 
containing the PMN substance, other than by incineration, deep well 
injection, or landfill. Disposal of the PMN substance, or waste steams 
containing the PMN substance, by landfill must use a hazardous waste 
landfill facility that is in compliance with RCRA subtitle C and D;
    <bullet> No release of the PMN substance, or any waste stream 
containing the PMN substance, resulting in surface water concentrations 
that exceed 140 ppb; and
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain

irritation, pulmonary effects, specific target organ toxicity, and 
aquatic toxicity testing may be potentially useful to characterize the 
health and environmental effects of the PMN substance. Although the 
Order does not require these tests, the Order's restrictions remain in 
effect until the Order is modified or revoked by EPA based on 
submission of this or other relevant information.

    Chemical Name: Sulfonium, bis(dihalo 
carbomonocycle)carbomonocycle-. salt with dihalo-sulfoalkyl 
[(alkenylcarbomonocycle)substituted] trisubstituted benzoate, polymer 
with alkenylcarbomonocycle and alkylcarbomonocycle alkyl alkenoate 
(generic).
    CASRN or Accession No.: 303323.
    Effective Date of TSCA Order: June 23, 2025.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use of the PMN substance will be as an ingredient used in 
the manufacture of photoresist. Based on the physical/chemical 
properties of the PMN substance (as described in the New Chemical 
Program's PBT category at 64 FR 60194; November 1999) and in the 
absence of data, the cation of the PMN substance and the cation 
photodegradation product are potentially persistent, bioaccumulative, 
and toxic (PBT) chemicals. EPA estimates that the cation of the PMN 
substance will persist in the environment for more than six months and 
that its potential to bioaccumulate is unknown. EPA estimates that the 
cation photodegradation product will persist in the environment for 
more than

[[Page 34493]]

six months and estimates a bioaccumulation factor of greater than or 
equal to 5,000. Based on analogy to sulfonium compounds, EPA has 
identified concerns for acute toxicity, irritation to the skin, eyes, 
and respiratory tract, eye corrosion, neurological, and systemic 
effects for the sulfonium cation. Based on photoreactivity, EPA has 
also identified concerns for photosensitization. Based on comparison to 
analogous chemical substances, EPA has also identified concerns for 
genetic toxicity. Due to insufficient information, EPA was unable to 
estimate the environmental hazard of the PMN substance. The Order was 
issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substance may present an unreasonable 
risk of injury to human health or the environment. To protect against 
these risks, the Order requires:
    <bullet> No manufacture of the PMN substance beyond the time limits 
specified in the Order without submittal to EPA the results of certain 
testing described in the Testing section of the Order;
    <bullet> Use of personal protective equipment where there is a 
potential for dermal exposure;
    <bullet> Establishment of a hazard communication program, including 
human health and environmental precautionary statements on each label 
and in the SDS;
    <bullet> No processing of the PMN substance in any way that 
generates vapor, dust, mist, or aerosol in a non-enclosed process;
    <bullet> Use of the PMN substance only for the confidential use 
listed in the Order;
    <bullet> No domestic manufacture of the PMN substance (i.e., import 
only);
    <bullet> Import of the PMN substance only in solution unless in 
sealed containers weighing 5 kilograms or less; and
    <bullet> No exceedance of the confidential annual importation 
volume listed the Order.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially Useful Information: EPA has determined that certain

PMN substance may be potentially useful in support of a request by the 
PMN submitter to modify the Order, or if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that will be 
designated by this SNUR. The submitter has agreed not to exceed the 
time limits specified in the Order without performing the required Tier 
I and Tier II testing outlined in the Testing section of the Order.

IV. 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">https://www.epa.gov/laws-regulations</a>.

A. Executive Order 12866: Regulatory Planning and Review

    This action proposes to establish 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).

[[Page 34495]]

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 is 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.
    EPA always welcomes your feedback on the burden estimates. When 
submitting comments on these proposed SNURs, include comments about the 
accuracy of the burden estimate, and any suggested methods for 
improving the collection instruments or instruction or minimizing 
respondent burden, including through the use of automated collection 
techniques.

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 9 in fiscal year 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 $14,967 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).
