Assessing and Managing Chemicals under TSCA

Chemical Substances Undergoing Prioritization: Low Priority

EPA is proposing the following 20 chemical substances as low priority under the Toxic Substances Control Act (TSCA). The proposal is the second step in prioritization — a new process for reviewing chemical substances under the amended TSCA. To support a proposed priority designation, EPA considered reasonably available information for each chemical substance under its conditions of use against the criteria specified in TSCA section 6(b)(1)(A). A final designation of “low priority” means that a risk evaluation is not warranted at this time.

*Status is listed as either:
  • Initiated – The first step of the prioritization process, and the chemical is currently undergoing a screening level review of reasonably available information to information its priority designation;
  • Proposed – The second step of the prioritization process, when EPA proposes a chemical’s designation as either high or low priority for risk evaluation; or
  • High/Low - The final step of the prioritization process. This chemical has been designated as high or low priority for risk evaluation.
