DURAND, Wis. (AP) -

The Pepin County Board has declared a 10-mile ribbon of popular bluff land on the Wisconsin side of Lake Pepin off limits to frac sand development.

The ordinance passed on a 9-3 vote Wednesday night.

Mining proponents and some county board members criticized the proposal. But the Star Tribune reports residents around the villages of Pepin and Stockholm pushed for the frac-free zone.

Ordinance supporters argued that industrial sand projects would destroy the area's natural endowments, wreck property values and hurt tourism.

Wisconsin and Minnesota hold vast deposits of uniquely formed silica sand needed by oil and gas drillers in other states as part of a national boom in hydraulic fracturing to recover crude and natural gas.
