Proposed Revocation of Significant New Uses of Metal Salts of Complex Inorganic Acids

Краткое содержание

EPA is proposing to revoke the significant new use rule (SNUR) promulgated under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for two chemical substances which were identified generically as metal salts of complex inorganic oxyacids which were the subject of premanufacture notices (PMNs) P-89-576 and P-89-577. EPA issued a SNUR based on a TSCA section 5(e) consent order designating certain activities as significant new uses. EPA has received test data for the chemical substances and is proposing to revoke the SNUR.
