On July 10, 2024, the U.S. Environmental Protection Agency (EPA) published a compliance guide for its final methylene chloride risk management rule issued under the Toxic Substances Control Act (TSCA). According to EPA, the compliance guide will help industry, workers, and other interested stakeholders understand and comply with the new regulations to prevent injuries, long-term illnesses, and deaths. EPA also announced that in June 2024, it released a fact sheet on the rule containing information on who is subject to the rule along with a summary of compliance timelines. As reported in our May 17, 2024, memorandum, EPA issued on May 8, 2024, a final rule to address the unreasonable risk of injury to health that EPA identified as caused by methylene chloride under its conditions of use (COU). 89 Fed. Reg. 39254. According to EPA, the final rule will prevent serious illness and death associated with uncontrolled exposures to methylene chloride by preventing consumer access to methylene chloride and by restricting the industrial and commercial use of methylene chloride while also allowing for a reasonable transition period where an industrial and commercial use of methylene chloride is being prohibited, will provide a time-limited exemption for a critical or essential use of methylene chloride for which no technically and economically feasible safer alternative is available, and will protect workers from the unreasonable risk of methylene chloride while on the job. The final rule was effective July 8, 2024. For more information, please read the full memorandum.
