(1) The department shall exercise such supervision over restrictions, equipment, methodology and personnel in the management of solid wastes as may be necessary to enforce sanitary requirements; and the commission shall adopt such rules and regulations as may be needed to specify methodology and procedures to meet the requirements of this chapter, which shall include at a minimum:

(a) Criteria for the determination of whether any waste or combination of wastes is hazardous for the purposes of this chapter;

(b) Rules and regulations for the storage, treatment and disposal of solid wastes;

(c) Rules and regulations for the transportation, containerization and labeling of hazardous wastes, which rules shall be consistent with those issued by the United States Department of Transportation;

(d) Rules and regulations specifying the terms and conditions under which the permit board shall issue, modify, suspend, revoke or deny such permits as may be required by this chapter. Such rules and regulations shall include, and not by way of limitation, specific authority for the permit board to consider the financial capability and performance history of an applicant;

(e) Rules and regulations establishing standards and procedures for the safe storage or transportation of hazardous waste and for the safe operation and maintenance of hazardous waste treatment or disposal facilities or sites or equipment;

(f) A listing of those wastes or combinations of wastes which are not compatible, and which may not be stored or disposed of together;

(g) Procedures and requirements for the use of a manifest during the transport of hazardous wastes;

(h) Standards for financial responsibility to cover the liability, closure and post-closure of any site and perpetual care of a commercial hazardous waste landfill. Rules and regulations promulgated hereunder may include, and not by way of limitation, requirements for maintaining liability insurance coverage if such coverage is not required under rules and regulations promulgated by the United States Environmental Protection Agency;

(i) Rules and regulations establishing minimum distances within which any hazardous waste disposal facility may be located from any municipality, school, residence, church or health care facility;

(j) Other rules and regulations as the commission deems necessary to manage hazardous wastes in the state, provided that such rules and regulations shall be equivalent to the United States Environmental Protection Agency’s rules and regulations.

(2) In complying with this section the commission shall consider the variations within this state in climate, geology, population density and such other factors as may be relevant to the management of hazardous wastes. It is the intent of the Legislature that commercial hazardous waste landfills be located on those sites which, by virtue of their geologic conditions, provide a high degree of environmental protection. In carrying out the intent of this provision, the commission is authorized to adopt siting criteria for commercial hazardous waste landfills which are more stringent or extensive in scope, coverage and effect than the rules and regulations promulgated by the United States Environmental Protection Agency.

(3) Except as hereinafter provided, hazardous wastes shall not be disposed of in this state by the use of underground injection methods, as herein defined according to 40 CFR 260.10(74) to mean “subsurface emplacement of fluids through a bored, drilled, or driven well, or through a dug well, where the depth of the dug well is greater than the largest surface dimension.” This prohibition shall not apply to the disposal on the generation site of hazardous wastes generated in the production of oil or gas or in a commercial or manufacturing operation. Commercial hazardous waste underground injection wells designed or intended to dispose of multiple nonhomogeneous types of wastes from multiple sources other than the owner of the well are hereby prohibited in the State of Mississippi.

A commercial hazardous waste landfill shall not be located on the same site or within one thousand (1,000) feet of an existing or abandoned ordinary waste disposal site, unless the hazardous waste to be disposed of in said commercial landfill is specifically approved as exempted.

(4) After promulgation of the regulations required under this section, no person shall construct, substantially alter or operate any solid waste treatment or disposal facility or site, nor shall any person store, treat or dispose of any hazardous waste without first obtaining a permit from the permit board for such facility, site or activity. However, no person shall construct any new hazardous waste treatment or disposal facility or site or substantially alter any such existing facility or site, nor shall the permit board issue a permit for any such construction or alteration, until the commission has promulgated rules and regulations under the provisions of subsection (1)(j) of this section. Said rules and regulations shall be equivalent to counterpart rules and regulations of the Environmental Protection Agency whether now in effect or hereinafter promulgated. Any person who has made an application for a permit for an existing facility under this section shall be treated as having been issued such permit until such time as final administrative disposition of such application has been made unless the cause of such delay is the result of the failure of the applicant to furnish information reasonably required or requested in order to process the application.

(5) Any permit issued under this section may be revoked by the issuing agency at any time when the permittee fails to comply with the terms and conditions of the permit. Where the obtaining of or compliance with any permit required under this section would, in the judgment of the department, cause undue or unreasonable hardship to any person, the department may issue a variance from these requirements. In no case shall the duration of any such variance exceed one (1) year. Renewals or extensions may be given only after an opportunity has been given for public comment on each such renewal or extension.

(6) Information obtained by the commission concerning environmental protection including but not limited to information contained in applications for solid or hazardous waste disposal permits shall be public information and shall be made available upon proper request. Other information obtained by the commission, department, or permit board in the administration of Sections 17-17-1 through 17-17-47 concerning trade secrets, including, but not limited to, marketing or financial information, treatment, transportation, storage or disposal processes or devices, methods of manufacture, or production capabilities or amounts shall be kept confidential if and only if: (a) a written confidentiality claim is made when the information is supplied; (b) such confidentiality claim allows disclosure to authorized department employees and/or the United States Environmental Protection Agency (EPA); and (c) such confidentiality claim is determined by the commission to be valid. If the confidentiality claim is denied, the information sought to be covered thereby shall not be released or disclosed, except to the Environmental Protection Agency, until the claimant has been notified in writing and afforded an opportunity for a hearing and appeal therefrom, as with other orders of the commission. Disclosure of confidential information by the EPA shall be governed by federal law and EPA regulations. Misappropriation of a trade secret shall be governed by the Mississippi Uniform Trade Secrets Act, Sections 75-26-1 through 75-26-19.

(7) Anyone making unauthorized disclosure of information determined to be confidential as herein provided shall be liable in a civil action for damages arising therefrom and shall also be guilty of a misdemeanor punishable as provided by law.

(8) Notwithstanding any other provision of this chapter, the executive director, upon receipt of information that the generation, storage, transportation, treatment or disposal of any solid waste may present an imminent and substantial hazard to the public health or to the environment, may take any legal, equitable or other action, including injunctive relief, necessary to protect the health of such persons or the environment.
