The Resource Conservation and Recovery Act (RCRA) passed by the United States Congress in 1976 mandates the proper handling and disposal of hazardous waste. The United States Environmental Protection Agency (EPA), authorized by RCRA, administers and enforces these requirements found in Title 40 of the Code of Federal Regulations. While RCRA focuses on the management of hazardous waste from the point of generation to the point of disposal, referred to as “cradle to grave,” it also covers solid waste management in general and encourages recycling and alternative energy sources.
A hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment. RCRA defines a hazardous waste as a waste that is either “characteristic” or “listed.”
Characteristic “D” Waste includes any waste having one or more following characteristics:
The ignitability characteristic identifies wastes that can catch fire and sustain combustion. Ignitable wastes carry the waste code D001. The corrosivity characteristic (D002) identifies wastes that are acidic or alkaline (basic) and can readily corrode or dissolve flesh, metal, or other material. The reactivity characteristic (D003) identifies wastes that readily explode or undergo violent reactions. The EPA developed the toxicity characteristic to identify wastes likely to leach dangerous concentration of toxic chemicals into ground water. Specific constituents that exhibit the toxicity characteristic are listed in Table V of the RCRA Code and identified by EPA waste numbers D004 through D043.
The EPA has four lists for hazardous waste: the F list, the P list, the K list, and the U list.
