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 is the Agency's authority for taking this action?
EPA is publishing this document in the
Federal Register
as required by sections 5 of the Toxic Substances Control Act (TSCA), 15 U.S.C. 2601et seq.,
and corresponding EPA regulations.
Under TSCA, a chemical substance may be either an “existing” chemical substance or a “new” chemical substance, see
https://www.epa.gov/chemicals-under-tsca.
Any chemical substance that is not on EPA's TSCA Inventory of Chemical Substances (TSCA Inventory) is classified as a “new chemical substance,” while a chemical substance that is listed on the TSCA Inventory is classified as an “existing chemical substance.” See TSCA section 3(2) and (11). For more information about the TSCA Inventory, see
https://www.epa.gov/inventory.
Any person who intends to manufacture (including import) a new chemical substance for a non-exempt commercial purpose, or to manufacture or process a chemical substance in a non-exempt manner for a use that EPA has determined is a significant new use, is required by TSCA section 5 to provide EPA with a PMN, MCAN, or SNUN, as appropriate, before initiating the activity. EPA will review the notice, make a risk determination on the new chemical substance or significant new use, and take appropriate action as described in TSCA section 5(a)(3).
TSCA section 5(h)(1) authorizes EPA to allow persons, upon application and under appropriate restrictions, to manufacture a new chemical substance, or manufacture or process a chemical substance subject to a significant new use rule (SNUR) issued under TSCA section 5(a)(2), for “test marketing” purposes, upon a showing that the manufacture, processing, distribution in commerce, use, and disposal of the chemical substances will not present an unreasonable risk of injury to health or the environment. This is referred to as a test marketing exemption, or TME.
Premanufacture notification procedures for reviewing certain new microbial products of biotechnology are established in 40 CFR part 725. These pertain to MCANs and biotechnology exemptions, including TSCA experimental release applications (TERAs), TMEs for microorganisms, and Tier I and Tier II exemptions.
C. What action is the Agency taking?
This document provides notice of receipt and status reports for the covered period and certain submissions under TSCA section 5 and provides an opportunity to comment on this information. The Agency provides information about the receipt of PMNs, SNUNs, MCANs, and amendments to a previously submitted notice; test information; biotechnology exemption applications under 40 CFR part 725; TME applications; NOCs for new chemical substances; and a periodic status report on chemical substances that are currently under EPA review or have recently concluded review.
D. What should I consider as I prepare my comments for EPA?
1.
Submitting CBI.
Do not submit CBI to EPA through
https://www.regulations.gov
or email. If you wish to include CBI in your comment, please follow the instructions at
https://www.epa.gov/dockets/commenting-epa-dockets#rules
and clearly mark the information that you claim to be CBI. In addition to one complete version of the comment that includes CBI, a copy of the comment without CBI must be submitted for inclusion in the public docket. Information marked as CBI will not be disclosed except in accordance with procedures set forth in 40 CFR parts 2 and 703.
