The U.S. Environmental Protection Agency (EPA) is scheduled to publish a proposed rule on January 13, 2017, that would require a retrospective electronic notification of chemical substances on the Toxic Substances Control Act (TSCA) Inventory that were manufactured (including imported) for non-exempt commercial purposes during the ten-year time period ending on June 21, 2016. EPA would also accept such notices for chemical substances that were processed. The recent TSCA amendments require EPA to designate chemical substances on the TSCA Inventory as either “active” or “inactive” in U.S. commerce. EPA states in the pre-publication version of the proposed rule that it would use these notifications to distinguish active substances from inactive substances. EPA would include the active and inactive designations on the TSCA Inventory and as part of its regular publications of the Inventory. EPA also proposes to establish procedures for forward-looking electronic notification of chemical substances on the TSCA Inventory that are designated as inactive, if and when the manufacturing or processing of such chemical substances for non-exempt commercial purposes is expected to resume. According to the proposed rule, upon receipt of a valid notice, EPA would change the designation of the pertinent chemical substance on the TSCA Inventory from inactive to active. The proposed rule includes the procedures to submit retrospective and forward-looking activity notifications, the details of the notification requirements, exemptions from such requirements, and procedures for handling claims of confidentiality. Publication of the proposed rule will begin a 60-day comment period. More information on the final rule will be available in our forthcoming memorandum, which will be available on our website under the key phrase TSCA.
