(1) Hazardous wastes shall not be handled or disposed of along with or in the same site or adjoining site as ordinary wastes unless specifically approved as exempted waste by the department. These shall be disposed of by special incinerators, separate landfills, or other means dictated by the particularities of the hazardous waste involved, as determined by the department or other responsible agency. The department may, in its discretion, maintain a field office at any treatment or disposal facility that receives hazardous wastes directly or indirectly from more than one (1) generator. However, the department shall maintain a field office at any commercial off-site multiuser hazardous waste incinerator designed to incinerate multiple nonhomogeneous types of wastes, and the cost of operating such field office shall be borne by the owner of such commercial hazardous waste incinerator. The field office, when required, shall be located in adequate accommodations provided by the facility owner and shall be staffed with department regulatory personnel as deemed necessary by the department. In exercising its discretion to determine the need for a field office, regulatory staff and support equipment, the department shall consider, at a minimum, the type and amount of hazardous waste received and also the type of facility. All fees shall be established by the department and shall be in addition to any other fees provided by law. The fee prescribed by the department shall be in an amount not less than the actual operating expenses of the permanent field office and shall be in addition to any other fees required by law.

(2) In addition to considering all applicable state and federal laws and regulations, the Mississippi Pollution Control Permit Board shall not issue a permit for the establishment or operation of a commercial hazardous waste landfill for the disposal of hazardous waste (as defined by Section 17-17-3, Mississippi Code of 1972), in the State of Mississippi until the Environmental Protection Agency makes a final determination, pursuant to the Federal Hazardous and Solid Waste Amendments of 1984, P.L. No. 98-616, that each waste to be placed in such landfill is suitable for land disposal.
