Comparison: State vs. Federal

Rules. Wisconsin follows the federal requirements for generators accumulating (storing) 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 Wisconsin as of September 1, 2020. The state has added several more stringent rules in connection with licensing permitted storage facilities and with on-site accumulation of hazardous waste by very small quantity generators (VSQGs).

Administration and enforcement. The Wisconsin Department of Natural Resources' (DNR) Environmental Management Division administers and enforces the hazardous waste storage rules in Wisconsin.
