Hazardous Materials: Hazardous Substances-Revisions

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 Appendix A, ``Hazardous Substances other than Radionuclides,'' to the Hazardous Materials Table. This action is necessary to comply with the Superfund Amendments and Reauthorization Act (SARA) of 1986, which amended the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) to mandate that RSPA regulate, under the HMR, all hazardous substances designated by the Environmental Protection Agency (EPA). The intended effect of this action is to enable shippers and carriers to identify CERCLA hazardous substances, thereby enabling them to comply with all applicable HMR requirements and to make the required notifications if a discharge of a hazardous substance occurs. No notice of proposed rulemaking (NPRM) has preceded this final rule because, in light of RSPA's lack of discretion concerning the regulation of hazardous substances under the HMR, RSPA finds that under the Administrative Procedure Act notice would serve no purpose and thus is unnecessary.
