The proposed project

Milestone Materials, a Division of Mathy Construction Company proposes an expansion of an existing sand pit and limestone quarry aggregate mining operation within the Rochester Sand and Gravel, North Quarry (an approximate 70 acre site). The expansion of aggregate mining operations involves the extraction of limestone aggregate from 60 feet to 120 feet below grade. Extraction of the limestone aggregate requires proposed dewatering by appropriating approximately 4,000 million (4 billion) gallons of water annually (or 333.3 million gallons of water per month) to access the limestone deposit. In addition, aggregate washing will occur on-site. The water appropriated for dewatering will be discharged to the South Fork of the Zumbro River after treatment within a series of settling ponds which will be constructed on site. Progressive reclamation of the site will occur as extraction of aggregate resources is completed on the site. The total project site is approximately 135 acres. The proposed project is located in Cascade Township in Olmsted County, Minnesota.
