Hazardous waste resources

The resources on this page are intended for persons and facilities generating, transporting, storing, treating and disposing of hazardous waste, universal waste and used oil. Please contact the hazardous waste program coordinator for situations not addressed here or for specific technical questions. 

Administrative codes and statutes

Wisconsin's Legislature creates and revises the Wisconsin Statutes (Wis. Stats.), while state agencies such as the Department of Natural Resources create and revise the rules required and authorized by those statutes. These agency rules constitute the Wisconsin Administrative Code (Wis. Adm. Code).

The majority of the hazardous waste requirements in state statutes and rules reflect mandates contained in the Resource Conservation and Recovery Act (RCRA) and federal regulations that Wisconsin hazardous waste rules must reflect.

Proposed rules

Public participation is a critical component of agency rulemaking and we value your involvement in DNR's rulemaking activities. There are numerous opportunities for you to participate in the DNR rulemaking process.
