Mississippi Code Title 17. Local Government; Provisions Common to Counties and Municipalities § 17-17-231

(1) The Commission on Environmental Quality may adopt rules and regulations governing municipal solid waste landfills that accept household wastes, but any rules and regulations for such landfills shall, except for the adoption of criteria and standards to be considered in the location of such facilities, be no more stringent or extensive in scope, coverage and effect than Subtitle D regulations promulgated by the United States Environmental Protection Agency.

(2) If Subtitle D regulations do not provide a standard, criteria or guidance addressing matters relating to landfills, the commission may promulgate rules and regulations to address these matters in accordance with the Mississippi Administrative Procedures Law when the commission determines that such rules and regulation are necessary to protect human health, welfare or the environment.

(3) Nothing in this section shall prohibit the commission by order or the Permit Board in the issuance or modification of a permit from placing additional requirements on a landfill on a case by case basis in order to prevent, abate, control or correct groundwater contamination, public endangerment or as otherwise determined necessary to protect human health, welfare or the environment.
