EPA extends PCE and CTC compliance deadlines

The Environmental Protection Agency (EPA) has extended the compliance dates of certain Workplace Chemical Protection Program (WCPP) requirements for perchloroethylene (PCE) and carbon tetrachloride (CTC) established under the Toxic Substances Control Act (TSCA).

Published on July 28, 2026, EPA’s final rule changes specific compliance dates but doesn’t alter the underlying WCPP requirements or the agency’s determination that PCE and CTC present unreasonable risks.

Who’s impacted?

The revised deadlines affect facilities subject to the TSCA PCE and CTC risk management rules finalized in 2024. These include entities that manufacture (including import), process, distribute in commerce, use, or dispose of:

• PCE,
• CTC, or
• Products containing PCE or CTC.

What are the new PCE and CTC compliance dates?

EPA’s final rule extends compliance deadlines for various WCPP requirements, including:

• Conducting initial monitoring,
• Meeting the existing chemical exposure limit (ECEL),
• Establishing a regulated area,
• Providing any required respiratory personal protective equipment (PPE) and establishing a respiratory PPE program,
• Implementing a workplace information and training program, and
• Establishing and implementing an exposure control plan (ECP).

Below is a summary of the new compliance deadlines.

* EPA maintains the CTC rule’s WCPP compliance date of December 3, 2027, to establish and implement an ECP.

Key to remember: EPA has extended compliance dates for certain PCE and CTC Workplace Chemical Protection Program requirements into 2027.
