It is defined in 40 CFR part 273, by the United States Environmental Protection Agency but states may also have corollary regulations regarding these materials.
Hazardous waste poses a possible threat to the human health or the environment. In the U.S., hazardous waste is regulated by the Resource Conservation and Recovery Act (RCRA), implemented by the U.S. Environmental Protection Agency (EPA). RCRA regulates the generation, storage, treatment and disposal of hazardous wastes (known as cradle to grave).
