(a) This Article sets forth permitting requirements and minimum operating standards for those hazardous waste disposal facilities which hold a valid Hazardous Waste Facility Permit from the Department of Toxic Substances Control and codispose nonhazardous, nonputrescible, industrial solid waste with hazardous waste in one or more waste management units within the disposal facility.

(b) This Article is adopted pursuant to and for the purpose of implementing the California Integrated Waste Management Act of 1989 (Act) commencing with Section 40000 of the Public Resources Code, as amended. These regulations should be read together with the Act.

(c) Nothing in this Article limits or restricts the power of any federal, state, or local agency to enforce any provision of law that it is authorized or required to enforce or administer, nor to limit or restrict cities or counties from promulgating laws which are at least as strict as the regulations contained in this Article. However, no city or county may promulgate laws which are inconsistent with the provisions of this Article or Title 22 California Code of Regulations, Division 4.5.

(e) These regulations are intended to provide a sufficient level of information and oversight to ensure that the codisposal of nonhazardous, nonputrescible, industrial solid waste at a hazardous waste disposal facility will be conducted in a manner which meets the purposes of the Act, as specified in Public Resources Code Section 40052, while protecting the public health, safety and the environment.
