EPA is revoking a significant new use rule (SNUR) promulgated under section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as substituted ethoxyethylamine phosphonate, which was covered by premanufacture notice (PMN) P-95-1950. EPA issued a SNUR designating certain activities as significant new uses based on the concern criteria. Subsequently, EPA received and reviewed new information and test data for the chemical substance. Based on the new information and test data, the Agency no longer finds that the activities not described in PMN P- 95-1950 constitute significant new uses.
