TSCA Inventory Notification (Active-Inactive) Requirements

The 2016 amendments to the Toxic Substances Control Act (TSCA) require EPA to designate chemical substances on the TSCA Chemical Substance Inventory as either ``active'' or ``inactive'' in U.S. commerce. To accomplish that, EPA is establishing a retrospective electronic notification of chemical substances on the TSCA Inventory that were manufactured (including imported) for nonexempt commercial purposes during the 10- year time period ending on June 21, 2016, with provision to also allow notification by processors. EPA will use these notifications to distinguish active substances from inactive substances. EPA will include the active and inactive designations on the TSCA Inventory and as part of its regular publications of the Inventory. EPA is also establishing 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 nonexempt commercial purposes is expected to resume. On receiving forward-looking notification, EPA will change the designation of the pertinent chemical substance on the TSCA Inventory from inactive to active. EPA is establishing the procedures regarding the manner in which such retrospective and forward-looking activity notifications must be submitted, the details of the notification requirements, exemptions from such requirements, and procedures for handling claims of confidentiality.
