On May 9, 2019, the U.S. Environmental Protection Agency (EPA) announced that it would soon be making available a signed action signed on May 6, 2019, that identifies chemical substances for inactive designation according to the Toxic Substances Control Act (TSCA) Inventory Notification (Active-Inactive) Requirements rule.  The pre-publication version of the notice is available here.  Specifically, EPA states that the signed action is a companion to the first version of the TSCA Chemical Substance Inventory with all listings designated as active or identified as inactive, which was posted on the EPA TSCA Inventory web page on February 19, 2019, and it will initiate a 90-day period after which substances identified as inactive will be designated as inactive.  Because the action was signed on May 6, 2019, inactive designations will become effective on Monday, August 5, 2019.  

Starting on 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.
