Description:  TITLE: Perchloroethylene (PCE); Revision to Toxic Substances Control Act (TSCA) Risk 
Determination; Notice of Availability  
AGENCY: Environmental Protection Agency (EPA ) 
ACTION: Notice  
SUMMARY: The Environmental Protection Agency (EPA) is announcing the availability of the final 
revision to the risk determination for the perchloroethylene (PCE) risk evaluation issued under the 
Toxic Substances Control Act (TSCA) . The revision to the PCE risk determination reflects the 
announced policy changes to ensure the public is protected from unreasonable risks from chemicals 
in a way that is su pported by science and the law. EPA determined that PCE, as a whole chemical

  substance, presents an unreasonable risk of injury to health when evaluated under its conditions of 
use. In addition, this revised risk determination does not reflect an assumptio n that workers always 
appropriately wear personal protective equipment (PPE). EPA understands that there could be 
adequate occupational safety protections in place at certain workplace locations; however, not 
assuming use of PPE reflects EPA's recognition that unreasonable risk may exist for subpopulations 
of workers that may be highly exposed because they are not covered by Occupational Safety and 
Health Administration (OSHA) standards, or their employers are out of compliance with OSHA 
standards, or becau se many of OSHA's chemical - specific permissible exposure limits largely adopted 
in the 1970's are described by OSHA as being "outdated and inadequate for ensuring protection of 
worker health," or because EPA finds unreasonable risk for purposes of TSCA no twithstanding OSHA 
requirements. This revision supersedes the condition of use -specific no unreasonable risk 
determinations in the December 20 20 PCE Risk Evaluation  and withdraws the associated TSCA order 
included in the December 2020 PCE Risk Evaluation.
