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.
Additionally, EPA published a final list of businesses that must pay a portion of the costs associated with those risk evaluations. Pursuant to TSCA, EPA conducts risk evaluations of high-priority chemical substances to determine whether those substances present an unreasonable risk to health or the environment. EPA splits the cost of these evaluations among manufacturers and importers of the chemical substances.
