Toxic Substances Control Act (TSCA) Reform Bill

Posted on December 1st, 2016

epaThe U.S. Senate and House of Representatives passed the Toxic Substances Control Act (TSCA) Reform Bill. For the first time in forty years, EPA will be amending TSCA to ensure that human and environmental health are considered in assessing the safety of chemicals. Further information can be found in the TSCA, as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act.

EPA announced on November 29th that the first 10 chemicals in a list of 90 will be evaluated under TSCA reform. Additional chemicals will be designated for evaluation, under the 2014 Work Plan. Per the Work Plan, as each risk evaluation is completed, EPA will begin another evaluation.  By the end of 2019, EPA will have at least 20 chemical risk valuations ongoing at any given time.

The first 10 chemicals were chosen based on EPA’s 2014 TSCA Work Plan for their potential for high hazard and exposure as well as other considerations.  Below is a list of the first 10 chemicals:

  • 1,4-Dioxane
  • 1-Bromopropane
  • Asbestos
  • Carbon Tetrachloride
  • Cyclic Aliphatic Bromide Cluster
  • Methylene Chloride
  • N-methylpyrrolidone
  • Pigment Violet 29
  • Tetrachloroethylene, (aka perchloroethylene)
  • Trichloroethylene

Once this list is published in the Federal Register, the law requires EPA to release a scoping document outlining the hazard(s), exposure(s), conditions of use, and the potentially exposed or susceptible subpopulation(s) the agency plans to consider for the evaluation. The bill also requires that a risk evaluation be completed within three years of publishing the list. This evaluation will determine whether the chemical presents an unreasonable risk to humans and the environment; if it does, EPA must mitigate that risk within two years.
