In 2001, Walworth County Board of Supervisors adopted a Nonmetallic Mining Reclamation Ordinance. This ordinance requires all operators of active nonmetallic mining sites have a Walworth County approved Reclamation Plan, Permit and Financial Assurance. The Reclamation Plan must comply with the State Standards specified in Chapter 135 of the Administrative Code (PDF).
Walworth County currently has 22 nonmetallic mining sites covering over 840 active acres.
