Comparison: State vs. Federal

Rules. Connecticut's closure and post-closure rules for hazardous waste TSDFs include the federal requirements and the state's additional rules for plan fees. In addition to complying with the general closure and post-closure standards, owners or operators of the various types of TSDFs have to meet closure and post-closure standards specific to their facility types. Connecticut follows the federal rules specific to facilities utilizing containers, hazardous waste storage tanks, hazardous waste landfills, land treatment, and surface impoundments.

Administration and enforcement. DEP's Engineering and Enforcement Division administers and enforces the TSDF closure and post-closure requirements in Connecticut.
