The EPA is proposing to designate 20 chemical substances as High-Priority Substances for upcoming risk evaluations, per a statutory requirement under the 2016 amendments to the Toxic Substances Control Act (TSCA) by. The proposed designation is a required step in a new process of reviewing chemical substances currently in commerce under the amended TSCA.
“By proposing to prioritize 20 chemicals for risk evaluation, EPA is realizing another one of the key requirements of the Frank R. Lautenberg Chemical Safety for the 21st Century Act,” said Assistant Administrator for EPA’s Office of Chemical Safety and Pollution Prevention Alexandra Dapolito Dunn. “Taking public comment will help advance our understanding about how these chemicals are used in commerce and brings EPA one step closer to completing the prioritization process.”
