EPA Proposes to Extend Compliance Dates in PCE, CTC Rules for Non-Federal Entities

A proposed rule published last week by EPA would extend certain compliance dates in its final risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC). Specifically, the proposal seeks to extend dates related to workplace chemical protection program (WCPP) requirements for non-federal owners and operators to match those for federal agencies and their contractors. 

Under the proposed rule, non-federal owners and operators would now have until June 21, 2027, to conduct initial monitoring for inhalation exposure to both PCE and CTC. The new compliance date for non-federal entities to meet EPA’s existing chemical exposure limits (ECELs) for both substances as well as comply with requirements to establish regulated areas, provide required respiratory personal protective equipment, and establish respiratory PPE programs would be Sept. 20, 2027. EPA’s proposed extension would also allow non-federal entities until Dec. 20, 2027, to establish and implement an exposure control plan for PCE. These proposed changes are intended to “address unanticipated WCPP/ECEL implementation difficulties” related to the agency’s final rules on PCE and CTC, according to a notice in the Federal Register.

“The proposed timeline adjustment does not weaken any existing protections and does not change the ultimate level of protection required,” EPA states in a news release.

The agency is accepting comments on its proposal until April 27. For more information, see the Federal Register notice.
