Significant New Use Notices (SN-23-0002 Through 0006 and SN-23-
0008 Through 0011); Extension of Review Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This document announces the extension of the review periods 
for significant new use notices (SNUNs) identified as SN-23-0002 
through 0006 and SN-23-0008 through 0011 submitted to the Environmental 
Protection Agency (EPA) under the Toxic Substances Control Act (TSCA). 
EPA has determined that an extension of the statutory 90-day review 
periods for these SNUNs is necessary to allow the Agency to complete 
the required analysis under TSCA, investigate potential risk, examine 
regulatory options, and prepare the necessary documents should the 
Agency determine that further regulatory action is required.

DATES: The review periods are extended to February 28, 2024.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This action is directed to the chemical manufacturing company that 
submitted the SNUNs. This action may also be of interest to persons 
concerned about health, environmental, and/or economic aspects of the 
significant new uses of the chemical substances. Since other entities 
may also be interested, the Agency has not attempted to describe all 
the specific entities that may be affected by this action.

B. How can I access the docket?

    The docket for this action, identified by docket identification 
(ID) number EPA-HQ-OPPT-2023-0061, is available online at https://www.regulations.gov or in-person at the Office of Pollution Prevention 
and Toxics Docket (OPPT Docket), Environmental Protection Agency Docket 
Center (EPA/DC), West William Jefferson Clinton Bldg., Rm. 3334, 1301 
Constitution Ave, NW, Washington, DC. The Public Reading Room is open 
from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The telephone number for the Public Reading Room is (202) 
566-1744, and the telephone number for the OPPT Docket is (202) 566-
0280. Please review the visitor instructions and additional information 
about the docket available at https://www.epa.gov/dockets.

C. What is EPA's authority for this action?

    TSCA section 5(c), 15 U.S.C. 2604(c), and 40 CFR 720.75(c) 
authorize EPA to extend, for good cause, the 90-day SNUN review period 
for additional periods of time not to exceed in the aggregate 90 days. 
Examples of circumstances in which EPA may find good cause to extend 
the review period include, but are not limited to, EPA's request for 
additional information relating to a notice during the notice review 
period, EPA's receipt of additional information relating to a notice 
during the notice review period, and EPA's determination that there is 
a significant possibility that a significant new use of a chemical will 
be regulated under TSCA sections 5(e) or 5(f) and additional time is 
required for EPA to initiate the appropriate regulatory action.

D. What action is the Agency taking?

    For the SNUNs identified in Unit II., EPA finds that there is good 
cause to extend the SNUN review periods. Based on the Agency's analysis 
to date, EPA has determined that extensions of the SNUN review periods 
are necessary to further investigate potential risk, examine regulatory 
options, and prepare the necessary documents, should regulatory action 
be required for the significant new uses of the chemical substances. 
Specifically, EPA received additional information and amendments to all 
nine of the notices during the review periods which required additional 
time for EPA to review and include in the assessment in order to 
determine and initiate the appropriate regulatory action.

II. What notices are subject to this extension?
