n-Methylpyrrolidone (NMP); Regulation Under the Toxic Substances Control Act (TSCA)
The Environmental Protection Agency (EPA or the "Agency") is proposing to address the unreasonable risk of injury to human health presented by n-methylpyrrolidone (NMP) under its conditions of use as documented in EPA's risk evaluation and risk determination for NMP pursuant to the Toxic Substances Control Act (TSCA). NMP is a widely used solvent in a variety of industrial, commercial, and consumer applications including the manufacture and production of electronics such as semiconductors, polymers, petrochemical products, paints and coatings, and paint and coating removers. EPA determined that NMP presents an unreasonable risk of injury to health due to the significant adverse health effects associated with exposure to NMP, including developmental post-implantation fetal loss from short-term exposure and reduced fertility and fecundity from long-term exposure. Additional adverse effects associated with exposure to NMP include liver toxicity, kidney toxicity, immunotoxicity, neurotoxicity, skin irritation, and sensitization. To address the identified unreasonable risk, EPA is proposing to: prohibit the manufacture (including import), processing, and distribution in commerce and use of NMP in several occupational conditions of use; require worker protections through an NMP workplace chemical protection program (WCPP) or prescriptive controls (including concentration limits) for most of the occupational conditions of use; require concentration limits on a consumer product; regulate certain consumer products to prevent commercial use; and establish recordkeeping, labeling, and downstream notification requirements.
