Some Exempt Wastes

Some businesses may generate wastes that are exempt or conditionally exempt from regulation as hazardous waste. Please review the following list of materials and refer to the specific code citations to determine if your waste is eligible for an exemption from the hazardous waste rules or reduced regulation.

Exempt or conditionally exempt

  • Empty containers that previously held non-acute hazardous waste. See s. NR 661.07 [exit DNR], Wis. Adm. Code.
  • Wastes that are discharged directly to a publicly owned treatment works (POTW) without being stored or accumulated first. The POTW must be notified of this discharge and the requirements of the POTW must be complied with. Wastes which are trucked to a POTW are not excluded. See s. NR 661.04(1) [exit DNR], Wis. Adm. Code.
  • Non-terne-plated used oil filters that have been gravity hot-drained. See s. NR 661.04(2)(m) [exit DNR], Wis. Adm. Code.
