PHMSA-2006-28711 (HM-145N): Hazardous Materials: Revisions to the List of Hazardous Substances and Reportable Quantities; Effective Date 3/31/2008

SUMMARY: PHMSA amends the Hazardous Materials Regulations (HMR) by revising the list of hazardous substances and reportable quantities (RQs) and by correcting editorial errors to the list of hazardous substances and RQs. Superfund (i.e., CERCLA) requires PHMSA to list and regulate all hazardous substances designated by the Environmental Protection Agency (EPA). This final rule enables shippers and carriers to identify the affected hazardous substances, comply with all applicable regulatory requirements, and make the required notifications if the release of a hazardous substance occurs.
