Today, in the Federal Register at 80 FR 37161, the Environmental Protection Agency (EPA) promulgated the attached amendments to Toxic Substances Control Act (TSCA) significant new use rules (SNURs) for 21 chemical substances which were the subject of premanufacture notices (PMNs).  This action modifies the requirements for persons who intend to manufacture (which includes import) or process these chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. 

In the Federal Register of April 9, 2015 (80 FR 19037), EPA proposed amendments to the SNURs for 24 chemical substances. For 20 of those chemical substances, EPA received no public comments and is issuing the SNURs as proposed.  For the chemical substance subject to the SNUR at 40 CFR 721.10182, EPA received three public comments supporting the proposed SNUR amendments, and EPA has clarified the allowed uses under the final modified rule.  EPA received public comments for the proposed SNUR amendments for the three remaining chemical substances, subject to SNURs at 40 CFR 721.5575, 721.9675, and 721.10515. EPA will finalize these proposed SNUR amendments in a separate action.
