The Environmental Protection Agency (EPA) recently met a key milestone of the Frank R. Lautenberg Chemical Safety for the 21st Century Act with the release of the updated Toxic Substances Control Act (TSCA) Inventory listing.

Because of the efforts made by thousands of stakeholders, manufacturers and processors from across the country, this information will help the EPA focus risk evaluation efforts on chemicals that are still on the market.

A major finding of the update is that only 47 percent of the chemicals on the current TSCA Inventory (86,000) are currently in commerce. Additionally, more than 80 percent of the chemicals in commerce have identities that are not confidential business information (CBI), meaning an increase in public access to their content. For the chemicals in commerce that have confidential identities, the EPA is currently developing a rule outlining how the Agency will review and substantiate all CBI claims that identify as confidential portions of the TSCA Inventory.

Companies have also been reminded that a Notice of Activity Form B (NOA) must be submitted by a manufacturer or processor for chemicals on the non-active TSCA Inventory.
