Hazardous Materials: Revisions to the List of Hazardous Substances and Reportable Quantities

Summary: In this final rule, RSPA is amending the Hazardous Materials Regulations (HMR) by revising the ``List of Hazardous Substances and Reportable Quantities'' that appears in the table, ``Hazardous Substances other than Radionuclides''. This action is required by the Superfund Amendments and Reauthorization Act (SARA) of 1986, which amended the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA). These laws require RSPA to regulate all hazardous substances designated by the Environmental Protection Agency (EPA). This final rule will enable shippers and carriers to identify the affected CERCLA hazardous substances, comply with all applicable HMR requirements, and make the required notifications if a discharge of a hazardous substance occurs.
