EPA Buys Labs 18 Months to Tame Methylene Chloride Menace
Published Date: 5/27/2025
Proposed Rule
Summary
The EPA is giving non-federal labs 18 more months to follow new rules about using methylene chloride, a chemical that needs careful handling. This change helps labs keep doing important work like cleaning up the environment and testing water without rushing. Everyone, from university labs to federal ones, will now have the same deadline, making it fair and easier to manage.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
18‑Month Delay for Non‑Federal Labs
If you run or work in a non‑federal laboratory (for example, a university lab or private testing lab), EPA is proposing to give your lab 18 more months to meet the Workplace Chemical Protection Program (WCPP) requirements and associated recordkeeping rules for methylene chloride. This is a proposed rule to extend the compliance dates for those non‑federal labs by 18 months.
Extension Aims To Prevent Monitoring Disruption
EPA proposes the 18‑month extension to avoid disrupting important functions such as environmental monitoring used at cleanup sites and wastewater treatment, and activities at university laboratories. Keeping those lab activities running helps protect safe air and water for people who use them.
Same Deadline for All Laboratories
EPA is proposing to align the compliance dates so that all laboratories — federal and non‑federal — have the same deadlines for the methylene chloride WCPP and related recordkeeping. The proposal makes the compliance schedule the same for laboratories currently subject to Federal agency and Federal contractor dates.
