Two months ago, the Environmental Protection Agency (EPA), under pressure from the courts, Congress, and the public, issued final regulations¹ implementing the complex hazardous waste regulatory program of Subtitle C of the Resource Conservation and Recovery Act (RCRA).² These regulations provide for the identification of wastes that are subject to regulation, establish a "manifest system" to track the waste from generation to final disposal, and establish standards for storage, treatment, and disposal facilities. In conjunction with the standards for generators and transporters of hazardous waste promulgated earlier this year³ and certain requirements of the consolidated permitting program issued on May 19,⁴ the regulations provide the first federal regulatory scheme to control hazardous waste, an environmental problem whose true dimensions are only now beginning to be understood.
