EPA Proposes New Deadline for Labs to Comply with TSCA Rules for Methylene Chloride

Posted on 5/29/2025 by Lion Technology Inc.

EPA proposed to extend, by 18 months, the deadline for non-federal laboratories to comply with workplace safety requirements for methylene chloride (MCL) established by a 2024 TSCA Final Rule.
The proposed rule would extend the deadlines for these labs to comply with the Workplace Chemical Protection Program (WCPP) for methylene chloride and related recordkeeping requirements.
Workplace Chemical Protection Program Requirements Proposed Deadline
Initial monitoring 11/6/2026
Establishing regulated areas and ensuring compliance with the existing chemical exposure limit 2/8/2027
Ensuring methods of compliance as well as developing and implementing an exposure control plan 5/10/2027
The proposed compliance deadlines match the deadlines for labs that are owned and operated by the Federal government or its contractors.

Methylene Chloride Rule: Prohibitions and Exemptions

EPA’s 2024 methylene chloride Final Rule prohibits manufacturing, processing, and distribution of methylene chloride for all consumer uses and most industrial uses. The rule provides an exemption for "critical or essential” uses of the chemical and for cases in which a safer alternative is not feasible.

For these non-prohibited uses, the 2024 Final Rule added requirements that employers must follow to protect workers from exposure to MCL, including the workplace chemical protection program (WCPP). With respect to ongoing uses of methylene chloride, the proposed rule says:
 

EPA is proposing to extend the compliance dates for associated laboratory activities detailed in this proposal to avoid disruption of important functions such as the use of environmental monitoring methods needed for cleanup sites and wastewater treatment, as well as activities associated with university laboratories.
