On September 28, the U.S. Environmental Protection Agency (EPA) released the approach it will use to identify chemicals that could be included in the next group of risk evaluations under the Toxic Substances Control Act (TSCA). Additionally, the Agency will be looking for input from the public on which chemicals should be prioritized for risk evaluation and which chemicals may be low priorities under TSCA.

The document lays out EPA’s near-term approach for identifying potential chemicals for prioritization, the initial step in evaluating the safety of existing chemicals under TSCA. Building on the Agency’s promise to work with the public to select the next chemicals for risk evaluation, this approach reflects public input received at a December 2017 meeting and through the public docket. By December 2019, EPA must designate at least 20 chemical substances as High-Priority for risk evaluation and 20 chemical substances as Low-Priority for which risk evaluation is not currently warranted.

The document also includes a longer-term risk-based strategy for managing the larger TSCA chemical landscape which, according to the TSCA Inventory, is composed of more than 40,000 active chemicals. This longer-term approach proposes parsing chemicals into “bins” that can be used to inform multiple activities and priorities throughout EPA, including within the TSCA program. After the Federal Register notice publishes EPA will open a public docket to accept comments on this longer-term strategy, which will inform its continued development and help outline a public meeting to be held in early 2019.

Upon publication of the Federal Register notice, EPA will open 73 chemical-specific public dockets, one for each of the remaining chemicals on the 2014 TSCA Work Plan. Additionally, there will be a general docket open for the public to suggest chemicals for risk evaluation that are not on the Work Plan. With this action, the Agency will be providing the public an opportunity to submit use, hazard, and exposure information on these chemicals. EPA will use this data to inform TSCA prioritization and risk evaluation for these chemicals.
