Non-metallic mining in the Town of Cottage Grove is regulated by TCG Ordinance Chapter 17 - Non-Metalllic Mining Sites. "No person may conduct nonmetallic mining within the Town limits without first obtaining a nonmetalic mining permit from the Town Board...A Public Hearing on the application for nonmetallic mining shall be scheduled within 30 days following receipt of the complete application and fees...Except as otherwise specifically noted, all nonmetallic mining permits shall be valid from July 1 of one year, to June 30 of the following year".
The Town of Cottage Grove currently has three active non-metallic mining sites, all of which have applied for renewal. Two of them are "non-conforming" sites, which means they were in existence prior to regulation by County Zoning, and thus are not subject to County Zoning regulations.
- The "Gaston Quarry" is a non-conforming site located at 2543 Gaston Road, operated by Wade and Brad Huston of R.G. Huston Company, Inc.
- The "Skaar Pit" at 3355 County Road N is also operated by Wade and Brad Huston of R.G. Huston Company, Inc. This site is regulated by Dane County CUP #2300.
- Wade Cattell of Raymond P. Cattell, Inc. operates a site located at 2294 US Highway 12 & 18 that is partially non-conforming and partially regulated by Dane County CUP #2405. There is also a concrete batch plant on this site which is regulated by Dane County CUP #2175.
