February 2, 2015 -- EPA published direct final significant new use rules (SNURs) for 27 chemical substances that were the subject of premanufacture notices (PMNs).
January 7, 2015 -- EPA proposed significant new use rules (SNURs) for 13 chemical substances that were the subject of premanufacture notices (PMNs).
December 23, 2014 -- EPA withdrew the significant new use rules (SNURs) for 30 chemical substances that were the subject of premanufacture notices (PMNs).
December 17, 2014 -- EPA proposed the revocation of the significant new use rules (SNURs) for two chemical substances that were the subject of premanufacture notices (PMNs) P-89-576 and P-89-577.
WARNING - DO NOT e-mail any Confidential Business Information (CBI) to EPA. EPA's e-mail system is NOT secured to protect CBI.
All new PMNs and SNUNs, as well as support documents (for notices submitted after April 6, 2010), must be provided to EPA via ePMN and CDX.
SNUN reminder: When submitting a Significant New Use Notice (SNUN), companies should include a cover letter. Read more information about SNUNs and what the cover letter should include.
Note: Having a Chemical Abstract Services Registry Number (CASRN) for a chemical does not equate to that chemical being listed on the TSCA Inventory.

Mandated by section 5 of the Toxic Substances Control Act (TSCA), EPA's New Chemicals program helps manage the potential risk to human health and the environment from chemicals new to the marketplace. The program functions as a "gatekeeper" that can identify conditions, up to and including a ban on production, to be placed on the use of a new chemical before it is entered into commerce. Section 5 of TSCA requires anyone who plans to manufacture (including import) a new chemical substance for a non-exempt commercial purpose to provide EPA with notice before initiating the activity. This premanufacture notice, or PMN, must be submitted at least 90 days prior to the manufacture of the chemical.
This Web site provides information on how the PMN process works and on related programs, including the existing chemicals programs under TSCA and the Sustainable Futures Initiative, which shows companies how to use the new chemicals program's computer models to screen PMNs or exemption notices before they submit them to EPA.
