Under the Toxic Substances Control Act (TSCA), EPA is proposing a significant new use rule (SNUR) for asbestos as defined under the Asbestos Hazard Emergency Response Act. The proposed significant new use of asbestos (including as part of an article) is manufacturing (including importing) or processing for certain uses identified by EPA as no longer ongoing. The Agency has found no information indicating that the following uses are ongoing, and therefore, the following uses are subject to this proposed SNUR: Adhesives, sealants, and roof and non-roof coatings; arc chutes; beater-add gaskets; extruded sealant tape and other tape; filler for acetylene cylinders; high-grade electrical paper; millboard; missile liner; pipeline wrap; reinforced plastics; roofing felt; separators in fuel cells and batteries; vinyl-asbestos floor tile; and any other building material (other than cement). Persons subject to the SNUR would be required to notify EPA at least 90 days before commencing any manufacturing (including importing) or processing of asbestos (including as part of an article) for a significant new use. The required notification initiates EPA’s evaluation of the conditions of use associated with the intended use within the applicable review period. Manufacturing (including importing) and processing (including as part of an article) for the significant new use may not 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.
