On June 22, 2017, as required by the amended Toxic Substances Control Act (TSCA), the US Environmental Protection Agency (US EPA) issued its rule to “reset” the TSCA Inventory. The rule requires every chemical manufacturer and importer to notify US EPA of each chemical substance it manufactured or imported for a non-exempt commercial purpose in the US during the 10-year period ending June 21, 2016 (the “lookback period”). Manufacturers and importers must provide this notification to US EPA within 180 days from the date on which the rule is formally published in the Federal Register. Each chemical substance for which US EPA receives such a notification will be designated as “active” on the TSCA Inventory.
