## Abstract

PHMSA amends the Hazardous Materials Regulations by removing saccharin and its salts from the list of hazardous substances and reportable quantities. The Comprehensive Environmental Response, Compensation and Liability Act, requires PHMSA to list and regulate all hazardous substances designated by statute or by the U.S. Environmental Protection Agency (EPA). EPA recently removed saccharin and its salts from their list of hazardous substances through notice and comment rulemaking. This final rule simply harmonizes the lists to better enable shippers and carriers to identify the affected hazardous substances, comply with all applicable regulatory requirements, and make required notifications if the release of a hazardous substance occurs.
