Milestone Materials has permission from Buffalo County Board of Adjustment for a limestone-mining project in rural Mondovi, the Winona Daily News reports.
The board voted 3-0 to give Milestone Materials a conditional-use permit to extract limestone from a new Buck Ridge Quarry site off Highway 37 in the Town of Mondovi. Milestone is a division of Mathy Construction, a company that operates stone extraction quarries and pits in Wisconsin and other states.
A plan calls for expanding an existing quarry purchased by the company in 2004 to 120 acres of adjoining land owned by Segerstrom & Sons of Mondovi.
The original quarry was issued a conditional-use zoning permit in 1991, but rock quarries dated back to the 1930s and 40s, zoning officials were told.
Under a 20-year lease agreement with Segerstrom & Sons, Milestone Materials intends to mine limestone from an estimated 60 acres of land located within an industrial sand mining site.
Segerstrom has conditional-use zoning permits for sand mining projects on 367 acres of land, including permits for dry and wet processing sites.
The county’s zoning department said dry processing structures for mined sand were constructed, but building of a wet processing facility and extraction of sand material has not yet occurred.
