What the agency says

The Environmental Protection Agency (EPA or Agency) is proposing to extend certain compliance dates applicable to certain entities subject to the regulation of trichloroethylene (TCE) under the Toxic Substances Control Act (TSCA) until December 31, 2027, including for certain chemical processors in meeting the prohibition compliance deadline for the processing of TCE, industrial and commercial use of TCE as a processing aid, and associated wastewater disposal; and for refrigerant manufacturers in meeting the compliance deadline for phasing down TCE feedstock in the production of HFC-134a. This proposed compliance extension would allow for necessary and reasonable transition periods for regulated entities under TSCA section 6(d).
