II. Test Data Submissions

Under 40 CFR 790.60, all TSCA section 4 enforceable consent agreements/orders must contain a statement that results of testing conducted pursuant to enforceable consent agreements/orders will be announced to the public in accordance with section 4(d) of TSCA.

Test data for N-methylpyrrolidone (NMP) were submitted by the NMP Producers Group on behalf of the member companies: Lyondell Chemical Company (formerly ARCO Chemical Company), BASF Corporation, and ISP Management Company, Inc. These data were submitted pursuant to a TSCA section 4 enforceable consent agreement/order and were received by EPA on November 23, 1999. The submission includes a final report entitled “N-Methylpyrrolidone - Carcinogenicity study in B6C3F1 mice; Administration in the diet for 18 months.” NMP is an inert, stable, polar solvent that is used in a wide variety of processes. Its commercial uses result from its strong and frequently selective solvent power. One of the major uses of NMP is the extraction of aromatics from lubricating oils. It is also used as a medium for polymerization and as a solvent for finished polymers. It is the preferred solvent in a variety of chemical reactions and the manufacture of numerous chemical intermediates and products such as plastics, surface coatings, and pesticides. An important use of this chemical is as a substitute for methylene chloride in paint strippers. NMP is also used in the recovery and purification of acetylenes, olefins, and diolefins, in the removal of sulfur compounds from natural and refinery gasses, and in the dehydration of natural gas.

EPA has initiated its review and evaluation process for this submission. At this time, the Agency is unable to provide any determination as to the completeness of the submission.
