"A number of terms (e.g., "hazardous chemicals," "hazardous materials," "hazardous waste," and similar nomenclature) refer to substances that are subject to regulation under one or more federal environmental laws. State laws and regulations also provide additional, similar, or identical terminology that may be confused with the federally defined terms. Many of these terms appear synonymous, and it is easy to use them interchangeably. However, in a regulatory context, inappropriate use of narrowly defined terms can lead to confusion about the substances referred to, the statutory provisions that apply, and the regulatory requirements for compliance under the applicable federal statutes."

Hazardous waste, as defined in federal law, is a solid waste or combination of solid wastes that, because of quantity, concentration or physical, chemical or infectious characteristics, may: (a) cause or significantly contribute to an increase in mortality or an increase in serious irreversible or incapacitating illness; or (b) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, disposed of or otherwise managed.
Hazardous waste means debris, materials, products, refuse or waste that, due to chemical, biological or physical properties, cannot be disposed of in a routine or common fashion due to potential threats to the health, safety and welfare of humans, natural and environmental resources or habitats. Wastes include but are not limited to corrosives, explosives, flammable materials, irritants, medical wastes, oxidizers, pesticides, poisons or other materials identified by applicable federal, state, or local legislation.
