Alkylpyrrolidones; Significant New Use Rule (7 pages, in English)

Under the Toxic Substance Control Act (TSCA), EPA is proposing a significant new use rule (SNUR) for two alkylpyrrolidones: N- ethylpyrrolidone (NEP) and N-isopropylpyrrolidone (NiPP) . The proposed significant new uses are any use of NiPP and any use of NEP except for the ongoing uses as a reactant, in silicone seal remover, coatings, consumer and commercial paint primer, and adhesives. Persons subject to the SNUR would be required to notify EPA at least 90 days before commencing any manufacturing or processing of the chemical substance for a significant new use. The required notification initiates EPA's evaluation of the conditions of use within the applicable review period. Manufacture and processing for the significant new use is unable to commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required in association with that determination.
