Miss. Code § 17-17-325
The authority may at the direction of the governing bodies of the participating units of local government submit a local nonhazardous solid waste management plan as required by Sections 17-17-201 through 17-17-235, to the Commission on Environmental Quality providing the authority's assurance of capacity for the management of municipal solid waste within the geographical boundaries of the authority for the period of not less than twenty (20) years.
The authority may designate a geographic area to the permit board within which the collection, transportation, storage, processing and disposal of all municipal solid waste generated within such area shall be accomplished in accordance with a local nonhazardous solid waste management plan. Such designation shall be made only after the permit board has received a resolution adopted by the unit or units of local government having jurisdiction within such geographic area that such designation be made and after approval of the commission of a local nonhazardous solid waste management plan.
The permit board shall not approve any permit application unless the facility is consistent with the applicable local nonhazardous solid waste management plan.
