A public hearing on El Na Farms’ proposed expansion is scheduled for 10 a.m. Tuesday at the Kewaunee County Land and Water Conservation Department, 625 Third Ave., Luxemburg.

The state Department of Natural Resources has made a preliminary ruling to approve the renewal of a Wisconsin Pollution Discharge Elimination System Permit that would allow the concentrated animal feeding operation at 4029 Pheasant Road, Algoma, to more than double the size of its herd.

According to the hearing notice, the farm has currently approximately 1,350 milking and dry cows, 850 heifers, and 500 calves equaling 2,675 animal units. Over the proposed permit term, the farm plans to expand through internal growth to approximately 5,970 animal units.

County Board Supervisor Lee Luft sent a reminder about Tuesday’s hearing to fellow members of the board’s Land and Water Conservation Committee on Monday evening.

“This expansion, if carried out, would require the land spreading of over 21 million additional gallons of untreated waste each year in what has been confirmed as the most sensitive area of Kewaunee and possibly Door counties,” Luft said. “Now that we are all aware of the extent of our groundwater contamination, it would seem more than irresponsible to add this much new waste to this most vulnerable area of our county.”
