Scope of the risk evaluation for N-Methylpyrrolidone (2-Pyrrolidinone, 1-Methyl-); CASRN: 872-50-4

U.S. Environmental Protection Agency 2017

Abstract  This document presents the scope of the risk evaluation to be conducted for n-methylpyrrolidone. If a hazard, exposure, condition of use or potentially exposed or susceptible subpopulation has not been discussed, EPA, at this point in time, is not intending to include it in the scope of the risk evaluation. As per the rulemaking, Procedures for Chemical Risk Evaluation Under the Amended Toxic Substances Control Act (TSCA), with respect to conditions of use in conducting a risk evaluation under TSCA, EPA will first identify “circumstances” that constitute “conditions of use” for each chemical. While EPA interprets this as largely a factual determination—i.e., EPA is to determine whether a chemical substance is actually involved in one or more of the activities listed in the definition—the determination will inevitably involve the exercise of some discretion.
