consisting of till, outwash, and glacial lake sediments cover the area,often to a thickness of several hundred feet. Bedrock consists of Cambrian sandstones overlain in some areas by Ordovician dolomites. Precambrian bedrock lies under the sandstone at depths of greater than 500 feet. Cambrian sandstone of the St. Peter Group underlies the dolomite. The WGNHS indicates quarry operations are mostly bedrock of the St. Peter Sandstone and the Prairie du Chien group consisting mostly of dolomite. The WGNHS indicates thicknesses up to 350 and 250 feet, respectively. Wisconsin Geologic and Natural History Survey(WGNHS)Report#HA-360 gives an overview of the regional groundwater regime. Depth to groundwater in the area of the mining operation is typically less than 150 feet according to the WGNHS report. This is supported by mining operations, with depths of approximately 70 feet and not encountering ground water. Groundwater moves away from high points on the potentiometric surface and discharges into lakes, streams,wetlands and areas of pumpage. Flow paths are short. The mining operation will be conducted above the groundwater table with a buffer of at least 5 feet. 4. Types and quantities of materials that will be extracted. Sand and gravel material is derived from crushed limestone bedrock. The CUPs will allow extraction of materials at this site as well as production stockpiles.The limestone will be mined until the area extends to the limits of the CUP area. Hardpan and other unsuitable material encountered during the mining operation, along with clean uncontaminated fill, are stockpiled to provide a source of backfill material during final reclamation activities. 5. Proposed dates to begin extraction,end extraction and complete reclamation. Initial extraction began in 1989. CUP petrttits have been renewed to continue mineral extraction. Rate of extraction is dependent on demand and market conditions. After mineral extraction the site will be graded and restored as open space.A reclamation plan has been prepared and will be followed. Extraction period is for 90 years.Attached drawings indicate the general contours anticipated during the restoration process. 6. Proposed hours and days of operation. Hours of operation shall be as follows: a. Operations,excluding blasting,may begin at 6:00 am Monday-Saturday. b.Blasting may begin at 7:00 am Monday-Saturday. i, t c.Drilling,blasting and crushing shall cease at 7:00 pm Monday-Friday and at 12:00 noon on --1r Satarday. d. Equipment and vehicles not involved in quarry operations may enter and leave the site outside t" i of the stated hours of operations. Non-quarrying supplies and equipment may be loaded and unloaded from vehicles;and equipment and vehicles may be repaired and maintained outside the stated hours of operation. Some equipment warm up and cool down time may also be allowed. 7. Geologic composition and depth of the mineral extraction. Based on existing mining operations, anticipated depth of limestone extraction is up to 100 feet. 8. Identify all major proposed haul routes to the nearest Class A highway or truck route. Indicate traffic flow patterns. Conditional Use Permit—Mineral Extraction Updated December 9,2016 NE 1/4 of the NE 1/4 Sec..26,T8N,RIOE Madison Crushing&Excavating.,Inc.
