Such wastes include, but are not limited to, those which are toxic, carcinogenic, flammable, irritants, strong sensitizers, or which generate pressure through decomposition, heat or other means, as well as containers and receptacles previously used in the transportation, storage, use or application of the substances described as a hazardous waste.
(3) The term “generation” means the act or process of producing hazardous waste.
(3A) The term “generator” means any person by site whose act or process produces hazardous waste or whose act first causes a hazardous waste to be subject to regulation.
(3B) The term “manifest” means the form used for identifying the quantity, composition, and the origin, routing and destination of hazardous waste during its transportation from the point of generation to the point of disposal, treatment, or storage.

(A) The term “source reduction” means any practice that:
(i) Reduces the amount of any hazardous substance, pollutant, or contaminant entering any waste stream or otherwise released into the environment, including fugitive emissions, prior to recycling, treatment, or disposal; and
(ii) Reduces the hazard to public health and the environment associated with the release of a hazardous substance, pollutant, or contaminant.

(9) The term “treatment facility” means a location for treatment, including an incinerator or a facility where generation has occurred.
