Significant New Use Rules on Certain Chemical Substances (24-
4.5e)

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.

DATES: Comments must be received on or before May 5, 2025.

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 identified in Unit III. 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:

[[Page 14744]]

     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 (e.g., 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 May 5, 2025 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.
2. Estimated Costs 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 
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.
1. Estimated Costs for SNUN Submissions
    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)) per fiscal year 2022. 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.

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

1. Submitting CBI

II. Background

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

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:
     The projected volume of manufacturing and processing of a 
chemical substance.
     The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
     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 the 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 these findings outlined in Unit III., 
TSCA section 5(e) Orders requiring the use of appropriate exposure 
controls were

[[Page 14745]]

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 wants:
     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).
     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.
     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.

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), 
5(h)(2), 5(h)(3), and 5(h)(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 https://www.epa.gov/tsca-import-export-requirements.

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 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

[[Page 14746]]

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 https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce.
    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 April 4, 2025 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:
     PMN number (the proposed CFR citation assigned in the 
regulatory text section of the proposed rule).
     Chemical name (generic name if the specific name is 
claimed as CBI).
     Chemical Abstracts Service Registry Number (CASRN) or 
Accession Number (if assigned for non-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 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).

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

    The substances subject to the proposed SNURs in this document are 
as follows:
PMN Number: P-18-360 (40 CFR 721.12077)
    Chemical Name: Oxirane, 2-methyl-, polymer with 2,4-diisocyanato-1-
methylbenzene, 2-methyloxirane polymer with oxirane ether with 1,2,3-
propanetriol (3:1), and oxirane, cashew nutshell liq.- and Pr alc. -
blocked.
    CASRN: 1227870-90-7.
    Effective Date of TSCA Order: May 2, 2024.
    Basis for TSCA Order: The PMN states that the use will be as a two-
component adhesive and protective coating for marine and infrastructure 
applications. Based on test data for the residual, EPA has identified 
concerns for skin sensitization, and skin, eye, and respiratory tract 
irritation for the feedstock residual. 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:
     No processing for use or use of the PMN substance in a 
consumer product;
     No use of the PMN substance other than as a two component 
adhesives and protective coating for marine and infrastructure 
applications;
     Use of a NIOSH-certified combination particulate and gas/
vapor respirator with an APF of at least 10 where there is a potential 
for inhalation exposure;
     Use of personal protective equipment where there is a 
potential for dermal exposure; and
     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 skin 
sensitization, skin irritation, and eye irritation 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.
PMN Number: P-20-87 (40 CFR 721.12078)
    Chemical Name: Alcohols, C8-10- iso-, C9-rich, ethoxylated.
    CASRN: 2368929-19-3.
    Effective Date of TSCA Order: March 21, 2024.
    Basis for TSCA Order: The PMN states that the use will be as a 
component in hard surface cleaners and laundry detergent. Based on a 
structural alert and the category of use, EPA has identified concerns 
for lung effects (surfactancy) and irritation to the skin,

[[Page 14747]]

eyes, and respiratory tract. Based on comparison to analogous chemical 
substances, EPA has also identified concerns for acute toxicity 
(mortality), skin and eye irritation, systemic effects, and 
reproductive/developmental effects. Based on comparison to analogous 
nonionic surfactants, EPA predicts toxicity to aquatic organisms may 
occur at concentrations that exceed 142 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:
     No processing of the PMN substance to a concentration of 
3% or greater in formulation for use in a consumer product;
     No use of the PMN substance other than as a surfactant in 
hard surface cleaners and laundry detergents;
     No release of the PMN substance, or any waste stream 
containing the PMN substance, in surface water concentrations that 
exceed 142 ppb;
     Use of a NIOSH-certified gas/vapor respirator with an APF 
of at least 1,000 where there is a potential for inhalation exposure;
     Use of personal protective equipment where there is a 
potential for dermal exposure; and
     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 
specific target organ toxicity, pulmonary effects, reproductive 
toxicity, developmental toxicity, skin irritation, eye damage, 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.
PMN Number: P-21-198 (40 CFR 721.12079)
    Chemical Name: Reaction product of polyester with alpha.-
hydro-.omega.-hydroxypoly (oxy-1,4- butanediyl) and 1,1'-
methylenebis[isocyanatobenzene] (generic).
    CASRN: 302217.
    Effective Date of TSCA Order: February 23, 2024.
    Basis for TSCA Order: The PMN states that the use will be as a hot 
melt moisture cure adhesive for the industrial floor and door industry. 
Based on comparison to analogous chemical substances for the residual, 
EPA has identified skin and respiratory sensitization, skin, eye, and 
respiratory tract irritation, acute toxicity, and pulmonary effects for 
the residual. 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:
     No manufacture, processing, or use of the PMN substance in 
any manner that results in inhalation exposure;
     No processing for use or use of the PMN substance in a 
consumer product;
     Use of personal protective equipment where there is a 
potential for dermal exposure; and
     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 skin 
sensitization, skin irritation, eye damage, and 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.
PMN Number: P-21-205 (40 CFR 721.12080)
    Chemical Name: Benzene, [2-[(2-methyl-1-undecen-1-yl) oxy]ethyl]-.
    CASRN: 2489743-82-8.
    Effective Date of TSCA Order: February 29, 2024.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as an additive in household consumer 
products. Based on submitted test data on the PMN substance, EPA has 
identified concerns for skin sensitization, systemic, and developmental 
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:
     No processing for use or use of the PMN substance in 
consumer products where the concentration of the PMN substance exceeds 
1% by weight;
     Use of personal protective equipment where there is a 
potential for dermal exposure; and
     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 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.

    Chemical Name: Sulfonium, tricarbocyclic-, polyfluoro-heteroatom-
substituted polycarbocyclicalkanesulfonate (1:1) (generic).
    CASRN: 302579.
    Effective Date of TSCA Order: April 26, 2024.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use of the PMN substance will be for photolithography. 
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 test data on structurally similar substances, the 
PMN substance is a potentially persistent, bioaccumulative, and toxic 
(PBT) chemical. EPA estimates that the anion, the incineration product, 
the cation, and the cation photodegradation product of the PMN 
substance will persist in the environment for more than six months, 
estimates a bioaccumulation factor for the cation photodegradation 
product of the PMN substance of greater than or equal to 1,000, and 
estimates an unknown bioaccumulation factor for the cation and anion of 
the PMN substance. Based on sulfonium compounds, EPA has identified 
concerns for acute toxicity, irritation to the skin, eyes, and 
respiratory tract, eye corrosion, ocular lethality, neurological 
effects, and systemic effects for the sulfonium cation of the PMN 
substance. Based on the photo reactivity of the PMN substance, EPA has 
also identified concerns for photosensitization for the sulfonium 
cation of the PMN substance. Based on the reactivity of the PMN 
substance, EPA has also identified concerns for irritation to the skin, 
eyes, and respiratory tract for the sulfonium cation of the PMN 
substance. Based on comparison to analogous chemical substances, EPA 
has also identified concerns for mutagenicity for the sulfonium cation 
of the PMN substance. Based on comparison to analogous chemical 
substances for the perfluoro anion, EPA has also identified concerns 
for acute toxicity, skin irritation, eye corrosion, GI tract 
irritation, and systemic, reproductive, and developmental effects for 
the anion. Based on a potential incineration by-product, EPA has also 
identified concerns for local, neurotoxic, and systemic effects. 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:
     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;
     Use of personal protective equipment where there is a 
potential for dermal exposure;
     Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS;
     No modification of the processing or use of the PMN 
substance in any way that generates a vapor, dust, mist, or aerosol in 
a non-enclosed process;
     Use of the PMN substance only for the confidential use 
listed in the Order;
     No domestic manufacture of the PMN substance (i.e., import 
only);
     Import of the PMN substance only in solution, unless in 
sealed containers weighing 5 kilograms or less; and
     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 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.

carbomonocycle-, salt with dihalo-sulfoalkyl trisubstituted benzoate 
(generic) (P-23-176) and Sulfonium, 
bis(dihalocarbomonocycle)carbomonocycle-, salt with substituted-
dihalobenzoate (generic) (P-23-179).
    CASRN: 302386 (P-23-176), not available (P-23-179).
    Effective Date of TSCA Order: March 6, 2024.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) use of the PMN substances will be as ingredients used in 
the manufacture of photoresist. 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 test data on 
structurally similar substances, the PMN substance 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 1,000. Based on sulfonium compounds, EPA has identified 
concerns for acute toxicity, irritation to the skin, eyes, and 
respiratory tract, eye corrosion, neurological effects, and systemic 
effects for the sulfonium cation of the PMN substances. Based on 
comparison to analogous chemical substances, EPA has also identified 
concerns for genetic toxicity. Based on the photo reactivity of the PMN 
substances, EPA has also identified concerns for photosensitization. 
Based on comparison to analogous chemical substances, EPA has also 
identified concerns for systemic and developmental effects for the 
anion component of the PMN substances. Based on a potential 
incineration product, EPA has also identified concerns for local and 
systemic effects via inhalation exposure. Based on OECD Toolbox 
results, EPA also identified concerns for skin sensitization (P-23-176) 
for the anion. Based on DEREK prediction for the anion, EPA has also 
identified systemic (thyroid) toxicity (P-23-179) for the anion. 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:
     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;
     Use of personal protective equipment where there is a 
potential for dermal exposure;
     Establishment of a hazard communication program, including 
human health precautionary statements on each label and in the SDS;
     No processing of the PMN substances in any way that 
generates a vapor, dust, mist, or aerosol in a non-enclosed process;
     Use of the PMN substances only for the confidential uses 
listed in the Order;
     No domestic manufacture of the PMN substances (i.e., 
import only);
     Import of the PMN substances only in solution, unless in 
sealed containers weighing 5 kilograms or less; and
     No exceedance of the confidential annual importation 
volumes 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.

that the anion, the cation, the incineration product, and the cation 
photodegradation product of the PMN substance will persist in the 
environment for more than six months. EPA estimates that the anion and 
the cation have unknown bioaccumulation potential, that the 
incineration product may accumulate in organisms by mechanisms other 
than lipophilic partitioning, and that the cation photodegradation 
product has a bioaccumulation factor of greater than or equal to 1,000. 
Based on sulfonium compounds, EPA has identified concerns for acute 
toxicity, irritation to the skin and respiratory tract, eye corrosion, 
neurological effects, and systemic effects for the sulfonium cation of 
the PMN substance. Based on comparison to analogous chemical 
substances, EPA has also identified concerns for genetic toxicity for 
the sulfonium cation of the PMN substance. Based on the photo 
reactivity of the PMN substance, EPA has also identified concerns for 
photosensitization for the sulfonium cation of the PMN substance. Based 
on OECD QSAR Toolbox results, EPA has also identified concerns for skin 
and respiratory tract sensitization for the anion. Based on an

    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use of the PMN substance will be for contained use for 
microlithography for electronic device manufacturing. 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

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 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).

B. 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. Send any 
comments about the accuracy of the burden estimate, and any suggested 
methods for improving the collection instruments or instruction or 
minimizing respondent burden, including using automated collection 
techniques.

C. 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

[[Page 14758]]

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, 13 in 
FY2021, 11 in FY2022, and 15 in FY2023, 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.

D. 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.

E. 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.

F. 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.

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

    This action is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997), because it does not concern an environmental health or 
safety risk. Since this action does not concern 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.

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

    This action is not a ``significant energy action'' as defined in 
Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not 
likely to have a significant adverse effect on the supply, 
distribution, or use of energy.

I. National Technology Transfer and Advancement Act (NTTAA)

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