No commercial site for the disposal of hazardous waste and hazardous substances shall during any calendar year receive and dispose of more than 600,000 tons of waste that cannot be legally disposed of in a solid waste landfill permitted under Subtitle D of RCRA 42 U.S.C. §6941.

Provided, however, that the Environmental Management Commission or its designee may allow the disposal of hazardous wastes in excess of the 600,000 ton annual limitation of volume imposed in this section if such action is determined by the Environmental Management Commission or its designee to be necessary to protect human health or the environment in the state. Provided further, if the commission determines that public awareness of environmental matters may be enhanced by special events or if amnesty or similar programs will promote the protection of human health and the environment of Alabama, then it may exempt any wastes so collected from the limitation of volume provisions of this section. Provided further, the Governor, or his designee, may allow the disposal of hazardous waste in excess of the 600,000 ton annual limitation of volume imposed in this section if such action is necessary to allow the state to comply with its obligations to assure disposal capacity pursuant to applicable state or federal law.

Notwithstanding the foregoing the operator of a commercial site for the disposal of hazardous waste and hazardous substances shall not be permitted to dispose of any "household waste" as defined in 40 C.F.R. 261.4(b), except residuals from incineration of such waste and household hazardous waste or with prior approval by the Alabama Department of Environmental Management.
