What is a spill?

Spill are discharges of hazardous substances that adversely impact, or threaten to adversely impact, human health, welfare or the environment and require an immediate response.

For detailed information on spill reporting requirements, see Section 292.11, Wis. Stats. [PDF exit DNR] and Chapter NR 706, Wis. Admin. Code [PDF exit DNR].

Do I have to report my spill?

Your spill is reportable to the DNR if:

  • there is an impact to human health;
    Note: An evacuation is considered a threat to human health.
  • there is an impact to the environment;
    Note: Water of the state includes a threat or spill into a sanitary sewer, storm sewer, and/or surface water.
  • there is a fire, explosion or safety hazard;
    Note: A slippery road condition is considered a safety hazard.
  • you have not immediately cleaned up the spill;
    Note: Has it evaporated or been cleaned up in accordance with NR700-726?
  • the spill was more than the reportable quantities listed below.*
