Per the TSCA Inventory Notification (Active-Inactive) Requirements final rule, inactive chemical designations become effective 90 days after the signature of the Availability of the Initial TSCA Inventory Memorandum, which is August 5, 2019. A pre-publication version of the Federal Register notice announcing the availability of this memorandum is available today here: TSCA Inventory Notification (Active-Inactive) Rule, and the memorandum will be available in the rulemaking docket (EPA-HQ-OPPT-2016-0426) upon publication of the Federal Register notice.
Starting August 5, 2019, manufacturers and processors are required to notify EPA before reintroducing into commerce a substance designated as inactive on the TSCA Inventory. Manufacturers and processors can notify EPA via a Notice of Activity Form B, found in EPA’s Central Data Exchange (CDX). Upon receiving such notification, EPA will change the designation of substances from inactive to active.
The Toxic Substances Control Act (TSCA), as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, requires EPA to designate chemical substances on the TSCA Chemical Substance Inventory as either “active” or “inactive” in U.S. commerce. EPA finalized a rule requiring industry reporting of chemicals manufactured (including imported) or processed in the U.S. over a 10-year period ending on June 21, 2016 and the reporting was completed on October 5, 2018.
This reporting was used to identify chemicals on the Agency’s current publication of the 2019 TSCA Inventory as active (i.e., already reported or exempt) or inactive (i.e., not reported or exempt).
