The EPA issued a new regulation for TSCA in May 2024. This new regulation bans almost all industrial, commercial, and consumer uses of Methylene Chloride/ Dichloromethane (CAS # 75-09-2). There are now many new restrictions and conditions on continued use of methylene chloride. As part of the regulations, EPA requires exposure monitoring for all uses of methylene chloride on campus. EHS provides resources and information for TSCA compliance.
