Perchloroethylene (PCE) and Carbon Tetrachloride (CTC); Regulation Under the Toxic Substances Control Act (TSCA); Compliance Date Extensions

What it does

The Environmental Protection Agency (EPA or Agency) is proposing to extend certain compliance dates applicable to certain entities subject to the regulation of perchloroethylene (PCE) and carbon tetrachloride (CTC) under the Toxic Substances Control Act (TSCA). EPA is proposing to extend certain Workplace Chemical Protection Program (WCPP) compliance dates for non-federal owners and operators to match the compliance dates for federal agencies and their contractors. For both PCE and CTC, this proposal would extend the compliance date for initial monitoring for inhalation exposure to June 21, 2027, and extend the compliance date to meet the existing chemical exposure limit (ECEL), establish a regulated area, provide any required respiratory personal protective equipment (PPE), and establish a respiratory PPE program to September 20, 2027. For PCE, EPA is also proposing to extend the compliance date for non-federal entities to establish and implement an exposure control plan to December 20, 2027.
