KEWAUNEE COUNTY, WI (WTAQ-WLUK) – The state has settled with a Kewaunee County dairy farm over runoff violations.
Attorney General Josh Kaul’s office says Rolling Hills Dairy, a concentrated animal feeding operation, has agreed to pay $144,000 and build additional runoff controls.
The state alleged the farm unlawfully discharged contaminated runoff from its feed storage area to a tributary of the East Twin River on at least two occasions. The state says the Department of Natural Resources previously warned the farm of the potentially illegal discharges. Samples showed high levels of pollutants, including phosphorus, in the river. The East Twin River is classified as a trout stream and is on the state’s list of rivers that are impaired because of excess phosphorus.
The state made other allegations regarding DNR inspection access, failure to build runoff controls required by the farm’s pollutant discharge permit, storing feed in an unapproved location and spreading manure before a rainstorm.
