Yesterday, OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received a notice of proposed rulemaking (NPRM) from the EPA on “N-Methylpyrrolidone (NMP); Regulation under the Toxic Substances Control Act (TSCA)”.
According to the Spring 2023 Unified Agenda entry for this rulemaking:
“This proposed rulemaking will
address the unreasonable risk of injury to health presented by
n-methylpyrrolidone (NMP) under its conditions of use, as documented in EPA’s
2020 Risk Evaluation and 2022 revised risk determination. 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. 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.”
