LANNON – Attorney General J.B. Van Hollen announces that his office has filed a civil complaint and consent judgment in Waukesha County against Mill Valley Corporation in Lannon, Wisconsin. Mill Valley Corporation operates a non-metallic mining business with its principal operation at the Village of Lannon, as well as quarry operations at various locations in Waukesha and Washington Counties. The civil complaint alleges that Mill Valley Corporation did not have the required stormwater pollution prevention plans in place at its facilities located at Jackson, Lannon, and Sussex. The civil complaint further alleges that discharges at the Lannon quarry impacted one acre of wetland and four acres of primary environmental corridor land connected to the wetlands. Additional violations are alleged at the Richfield quarry.
Mill Valley Corporation has agreed to pay $200,000 in forfeitures, statutory surcharges, and costs, payable immediately upon execution of the judgment. The defendant further agrees to implement all of the activities required by its accepted stormwater pollution prevention plan and purchase 1.5 acres of wetland bank credit as consideration for the damage to the onsite wetland.
Assistant Attorney General Cynthia R. Hirsch prosecuted the case. The settlement was approved by Waukesha County Circuit Court Judge Donald J. Hassin, Jr. on January 19,2011.
