These agency rules constitute the Wisconsin Administrative Code (Wis. Adm. Code). The rules provided below are effective as of Sept. 1, 2020.

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.

    Inspection forms

    Hazardous waste inspection forms

    The DNR conducts compliance inspection at facilities generating hazardous waste and follows up on complaints. A best management practice for facilities is to conduct a self-audit using the DNR inspection forms below. The forms titled “Plain Language Inspection Form” are intended to provide streamlined regulatory requirements with simplified language when possible.

    The DNR has created the following documents to help people and facilities comply with hazardous waste requirements.
