## Abstract

EPA is revoking the significant new use rule (SNUR) issued under the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as alpha 1-, 3-polysaccharide, which was the subject of premanufacture notice (PMN) P-16-581. EPA issued a SNUR based on this PMN which designated certain activities as significant new uses. EPA is revoking the SNUR based on new test data for the chemical substance.
