What is a containment building?

A containment building is defined as a hazardous waste management unit that is used to store or treat hazardous waste under the provisions of Subpart DD of parts 264 or 265 (§260.10).

EPA developed the containment building standards to provide large quantity generators, and treatment and storage facilities, with a new management unit option for bulky, non-liquid hazardous wastes not amenable to accumulation, storage, or treatment in containers or tanks.
