As required by the amended Toxic Substances Control Act (TSCA), on June 22, 2017, one year after passage of the Frank R. Lautenberg Chemical Safety for the 21st Century Act, the U.S. Environmental Protection Agency (EPA) has issued the three framework rules in final. EPA also released draft guidance to assist in developing and submitting draft risk evaluations. The final rules are:

  1. Procedures for Chemical Risk Evaluation;
  2. Procedures for Prioritization of Chemicals for Risk Evaluation; and
  3. TSCA Inventory Notification (Active-Inactive) Requirements

EPA also released scoping documents of the risk evaluations and supplemental resources on the first ten chemicals under amended TSCA, as it stipulated in its annual report on risk evaluations. Links to the scoping documents for these ten chemicals, as well as strategies for conducting literature searches, are below:

  1. Methylene Chloride;
  2. 1-Bromopropane;
  3. N-Methylpyrolidone (NMP);
  4. Carbon Tetrachloride;
  5. Trichloroethylene;
  6. Cyclic Aliphatic Bromide Cluster (HBCD); and
  7. Tetrachloroethylene (perchloroethylene).

Administrator Scott Pruitt signed them and they were released to the general public shortly thereafter. They are expected to be effective 60 days after publication in the Federal Register.
