Under the Toxic Substance Control Act (TSCA), EPA is finalizing a significant new use rule (SNUR) for trichloroethylene (TCE). The significant new use is the manufacture or processing for use in a consumer product, with an exception for use of TCE in cleaners and solvent degreasers, film cleaners, hoof polishes, lubricants, mirror edge sealants, and pepper spray. Persons subject to the SNUR will be required to notify EPA at least 90 days before commencing any manufacturing or processing of TCE for a significant new use. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary based on the information available at that time, an opportunity to protect against potential unreasonable risks, if any, from that activity before it occurs.
