ABSTRACT
In 1984, Congress updated RCRA by prohibiting the land disposal of certain hazardous wastes, with the consequent enactment of the Land Disposal Restrictions (LDR) program by the U.S. EPA. The LDR program required that toxic constituents within hazardous waste be adequately treated prior to disposal of the waste on land. Since the enactment of the LDR program, mandatory technology-based treatment standards have been formulated, which must be met before hazardous waste is disposed on land. These standards have been extremely important in minimizing threats to human health and the environment.
