Comparison: State vs. Federal
• Rules. Minnesota's closure and post-closure rules for hazardous waste treatment, storage, and disposal facilities (TSDFs) parallel the federal requirements. The state has additional requirements for facilities using hazardous waste storage tanks and for TSDFs with surface impoundments.
• Administration and enforcement. The Land and Air Compliance Section of MPCA's Industrial Division administers and enforces the TSDF closure and post-closure requirements in Minnesota.
