Comparison: State vs. Federal

Rules. Wisconsin has adopted the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in the state as of September 1, 2020, which includes standards that allow generators to treat hazardous waste on-site. The state has added some more stringent state requirements in connection with hazardous waste treatment facility licensing and treatment facility fees. As under the federal rules, Wisconsin allows hazardous waste generators to treat hazardous waste on-site without a permit.

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