Agrichemical Spills

Reporting an Agrichemical Spill

The Spills Hotline, 1-800-943-0003, is answered 24-hours a day.

If you have a spill of pesticides or fertilizer greater than the reportable levels listed below, contact the Spills Hotline. Any spill that has adversely impacted or threatens to adversely impact public health, public welfare, or the environment must also be reported to Department of Natural Resources.

If there is no immediate threat to public health, public welfare, or the environment, reporting requirements are based on the quantity released, as follows:

  • Dry Fertilizer: Report the discharge to the DNR if the amount is 250 lbs. or greater.
  • Liquid Fertilizer: Report the discharge to the DNR if the amount is 25 gallons or greater.
  • Registered Agricultural Pesticides: Report the discharge to the DNR if the amount, when diluted according to the label, would cover one acre or more of land if applied according to the label instructions.

For spills of products other than pesticides and fertilizer, contact the Department of Natural Resources to determine whether or not the spill should be reported.

After the spill is reported, department staff can provide technical assistance and reimbursement of some costs for cleaning up contamination caused by pesticide and fertilizer spills. One common method of cleanup is excavating and landspreading the contaminated soils. Our staff will guide you through the landspreading process which requires a permit from our department.

For more information or assistance, email or call 608-224-4515 the spill coordinator or contact your local environmental enforcement specialist.
