CHEMICAL CATEGORIES IN EPA'S NEW CHEMICALS PROGRAM
Description:
Under section 5 of the Toxic Substances Control Act (TSCA),any person who intends to manufacture or import a new chemical substance, or mixture containing such a substance, in the United States for commercial purposes must submit a premanufacture notice (PMN) to the Environmental Protection Agency (EPA) at least 90 days prior to manufacture or import. EPAs Office of Pollution Prevention and Toxics, or OPPT, has grouped PMN chemicals with shared chemical and toxicological properties into categories so that both PMN submitters and EPA reviewers can benefit from the accumulated data and past decisional precedents, and reviews can be facilitated. This document lists and describes those categories in scientific terms; for each category, theNCP provides (1) a description of the category, (2) the basic chemical group that has raised concern, (3) typical testing requirements, and (4)boundaries of the category presenting health and environmental concerns--e.g., carbon chain length, molecular weight, or log P. If, based on an assessment of the potential exposures and releases associated with the new chemical, EPA concludes that the new substance may pose an unreasonable risk to human health or the environment, testing and restrictions may be required.
