Certain New Chemicals or Significant New Uses; Statements of 
Findings--July 2025 to September 2025

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Toxic Substances Control Act (TSCA) requires EPA to 
publish in the Federal Register a statement of its findings after its 
review of certain TSCA submissions when EPA makes a finding that a new 
chemical substance or significant new use is not likely to present an 
unreasonable risk of injury to health or the environment. Such 
statements apply to premanufacture notices (PMNs), microbial commercial 
activity notices (MCANs), and significant new use notices (SNUNs) 
submitted to EPA under TSCA. This document presents statements of 
findings made by EPA on such submissions during the period from July 1, 
2025, to September 30, 2025.

SUPPLEMENTARY INFORMATION: 

I. Executive Summary

A. Does this action apply to me?

    This action provides information that is directed to the public in 
general.

B. What action is the Agency taking?

    This document lists the statements of findings made by EPA after 
review of submissions under TSCA section 5(a) that certain new chemical 
substances or significant new uses are not likely to present an 
unreasonable risk of injury to

[[Page 273]]

health or the environment. This document presents statements of 
findings made by EPA during the applicable period.

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

    TSCA section 5(a)(3) requires EPA to review a submission under TSCA 
section 5(a) and make specific findings pertaining to whether the 
substance may present unreasonable risk of injury to health or the 
environment. Among those potential findings is that the chemical 
substance or significant new use is not likely to present an 
unreasonable risk of injury to health or the environment per TSCA 
Section 5(a)(3)(C).
    TSCA section 5(g) requires EPA to publish in the Federal Register a 
statement of its findings after its review of a submission under TSCA 
section 5(a) when EPA makes a finding that a new chemical substance or 
significant new use is not likely to present an unreasonable risk of 
injury to health or the environment. Such statements apply to PMNs, 
MCANs, and SNUNs submitted to EPA under TSCA section 5.
    Anyone who plans to manufacture (which includes import) a new 
chemical substance for a non-exempt commercial purpose and any 
manufacturer or processor wishing to engage in a use of a chemical 
substance designated by EPA as a significant new use must submit a 
notice to EPA at least 90 days before commencing manufacture of the new 
chemical substance or before engaging in the significant new use.
    The submitter of a notice to EPA for which EPA has made a finding 
of ``not likely to present an unreasonable risk of injury to health or 
the environment'' may commence manufacture of the chemical substance or 
manufacture or processing for the significant new use notwithstanding 
any remaining portion of the applicable review period.

II. Statements of Findings Under TSCA Section 5(a)(3)(C)

    In this unit, EPA identifies the PMNs, MCANs and SNUNs for which 
EPA has made findings under TSCA section 5(a)(3)(C) that the new 
chemical substances or significant new uses are not likely to present 
an unreasonable risk of injury to health or the environment. For the 
findings made during this period, the following list provides the EPA 
case number assigned to the TSCA section 5(a) submission and the 
chemical identity (generic name if the specific name is claimed as 
confidential).
    <bullet> P-24-0139, Maleic acid, dibutyl ester, reaction products 
with isophoronediamine-5-isocyanato-1-(isocyanatomethyl)-1,3,3-
trimethylcyclohexane-trimethylolpropane triacrylate polymer, di-Bu 
maleate and di-Et maleate (Generic Name).
    <bullet> P-24-0145, 2-Butenedioic acid (2Z)-, 1,4-bis(2-ethylhexyl) 
ester, reaction products with 5-amino-1,3,3-
trimethylcyclohexanemethanamine-hexamethylene diacrylate-isophorone 
diisocyanate polymer and di-Bu maleate (Generic Name).

likely to present an unreasonable risk'' finding made by EPA under TSCA
