On September 4, 2020, the U.S. Environmental Protection Agency (EPA) published scope documents for 20 high-priority chemicals that will undergo risk evaluation under the Toxic Substances Control Act (TSCA). The scope documents set frameworks for evaluating these 20 chemicals in light of their conditions of use, hazards, exposures, and potentially exposed or susceptible subpopulations. TSCA directs EPA to complete risk evaluations for these 20 chemicals over the next three years.
Companies have started reporting their manufacture or imports of newly designated high-priority substances under the Toxic Substances Control Act—and paying EPA costs for evaluating the substances’ risk. Sidley lawyers explain the risk evaluation process and how companies can strategically engage with EPA on the scope of risk evaluations.
