Hazardous Waste Management System; Carbamate Production, Identification and Listing of Hazardous Waste; Land Disposal Restrictions; Authorization of State Hazardous Waste Programs; and CERCLA Hazardous Substance Designation and Reportable Quantities

The Environmental Protection Agency (EPA) is amending its regulations to conform with the federal appeals court ruling in Dithiocarbamate Task Force v. EPA, 98 F.3d 1394 (D.C.Cir. 1996), that invalidated, in part, Agency regulations listing certain carbamate wastes as hazardous wastes under the Resource Conservation and Recovery Act (RCRA). These regulations pertain to hazardous waste management of carbamate industry wastes under RCRA, related rules affecting the list of hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and regulations issued under state programs approved by the Administrator. Under the court's decision, and amended in today's rule, the vacated federal hazardous waste listings and regulatory requirements based on those listings are to be treated as though they have never been in effect. State regulations, which may be more stringent than federal rules, were not necessarily affected by the court's ruling.
