2070-AK85 202404 Unified Agenda of Federal Regulatory and Deregulatory Actions 2070 Office of Chemical Safety and Pollution Prevention OCSPP 2000 Environmental Protection Agency EPA N-Methylpyrrolidone (NMP); Regulation Under the Toxic Substances Control Act (TSCA)

This proposed rulemaking will address the unreasonable risk of injury to health presented by n-methylpyrrolidone (NMP). Section 6(a) of the Toxic Substances Control Act (TSCA) requires EPA to address by rule any unreasonable risk identified in a TSCA section 6(b) risk evaluation by applying requirements to the extent necessary so the chemical no longer presents unreasonable risk. The Agency’s development of this rule incorporates significant stakeholder outreach and public participation, including over 40 external meetings as well as required Federalism, Tribal, and Environmental Justice consultations and a Small Businesses Advocacy Review Panel. EPA's 2020 risk evaluation for NMP, describing its conditions of use is in docket EPA-HQ-OPPT-2019-0236, with the 2022 revised unreasonable risk determination and additional materials in docket EPA-HQ-OPPT-2016-0743.
