Richfield Dairy WPDES permit
Supplemental Environmental Assessment for high capacity wells and modified high capacity well approval
The department has issued a supplemental Environmental Assessment (EA), Supplemental Environmental Assessment Comment Response Document and modified high capacity well approval for a proposed new dairy facility named Richfield Dairy and operated by Milk Source Holdings, Inc. The proposed dairy facility would house 4,300 milking/dry cows and 250 steers for a total of 6,270 animal units (AU), where one milking/dry cow is equivalent to 1.4 animal units, or a 1,400 pound animal. In addition to other proposed facility structures, the Richfield Dairy would include two high capacity water wells. The proposed Richfield Dairy facility would be located in the southeast corner of the intersection of 1st Drive and Cypress Avenue. Primary access to the facility would be from 1st Drive. Total site disturbance entails the conversion of 115 acres of existing cropland to farm buildings, production area and ancillary area.
The department prepared an Environmental Assessment (EA) for the proposed Richfield Dairy facility in November 2011. The EA was challenged in Dane County Circuit Court. The DNR prepared a Supplemental Environmental Assessment (SEA) for the proposed Richfield Dairy high capacity wells, based on a decision from the Dane County Circuit Court remanding the EA back to DNR because the EA did not adequately evaluate the effects of the high capacity wells at their approved pumping rate.
As directed by the court, DNR has now conducted additional factual investigation to allow a reasonably informed preliminary judgment about the environmental effects of the high capacity wells operating at 72.5 million gallons per year (MGY), which is the rate requested by the Richfield Dairy in a revised high capacity well approval application. The DNR has evaluated newly submitted information, including a numerical groundwater model submitted by the dairy (S.S. Papadopulos & Associates, 2012), and has evaluated all available information in order to make its preliminary judgment about the environmental effects of the high capacity wells operating at 72.5 MGY.
