Comparison: State vs. Federal
• Rules. New Hampshire's hazardous waste determination rules largely mirror the federal rules. However, the state did not adopt the "solid waste" prong of the federal test for hazardous waste determination, and its hazardous waste standards are stricter in several respects. New Hampshire excludes fewer substances from hazardous waste classification and has a greater number of listed wastes. The state has adopted the federal exemptions for solvent-contaminated wipes that are either laundered or disposed of in accordance with the state's requirements, which mirror the federal exclusion provisions. The state also adds criteria for determining if a waste is corrosive. For an explanation of the federal rules on hazardous waste classification, see the national section HAZARDOUS WASTE DETERMINATION.
• Administration and enforcement. The Waste Management Division of the New Hampshire Department of Environmental Services (DES) administers and enforces the state's hazardous waste determination rules.
