See national section for basic information and federal regulations.
Comparison: State vs. Federal
• Rules. Mississippi adopts by reference the federal hazardous waste storage rules for permitted and interim-status treatment, storage, and disposal facilities (TSDFs). In addition, the state follows the federal requirements for generators accumulating hazardous waste on-site without a permit through its adoption of the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Mississippi as of June 24, 2018. To the federal requirements for hazardous waste storage facilities, Mississippi adds state permit requirements and several storage and pollution prevention fees. See the state sections TSDF PERMITS and TSDF RESPONSIBILITIES for more information.
• Administration and enforcement. The Hazardous Waste Management Program at the Mississippi Department of Environmental Quality (DEQ) administers and enforces the hazardous waste storage rules in Mississippi.
