The mining operation will be conducted above the groundwater table with a buffer of at least 5 feet. <br /> d. Types and quantities of materials that will be extracted. <br /> Sand and gravel material is derived from crushed limestone bedrock. The CUPs will allow extraction <br /> of materials at this site as well as production stockpiles. The limestone will be mined until the area <br /> extends to the limits of the CUP area. <br /> Hardpan and other unsuitable material encountered during the mining operation,along with clean <br /> uncontaminated fill,are stockpiled to provide a source of backfill material during final reclamation <br /> activities. <br /> e. Proposed dates to begin extraction, end extraction and complete reclamation. <br /> Initial extraction began in 1989. CUP permits have been renewed to continue mineral extraction. <br /> Rate of extraction is dependent on demand and market conditions. After mineral extraction the site <br /> will be graded and restored as open space.A reclamation plan has been prepared and will be <br /> followed. Extraction period is for 90 years.Attached drawings indicate the general contours <br /> anticipated during the restoration process. <br /> f ' Proposed hours and days of operation. ! ' "' 1 „ , <br /> Hours of operation shall be as follows: <br /> a. Operations,excluding blasting,may begin at 6:00 am Monday-Saturday. <br /> b. Blasting may begin at 7:00 am Monday-Saturday. <br /> c. Drilling,blasting and crushing shall cease at 7:00 pm Monday-Friday and at 12:00 noon on <br /> Saturday. <br /> d. Equipment and vehicles not involved in quarry operations may enter and leave the site outside of <br /> the stated hours of operations. Non-quarrying supplies and equipment may be loaded and unloaded <br /> from vehicles; and equipment and vehicles may be repaired and maintained outside the stated hours of <br /> operation. Some equipment warm up and cool down time may also be allowed. <br /> g. Geologic composition and depth of the mineral extraction. <br /> Based on existing mining operations,anticipated depth of limestone extraction is up to 100 feet. <br /> h. Identify all major proposed haul routes to the nearest Class A highway or truck route. Indicate traffic <br /> flow patterns. <br /> Truck ingress and egress will be from Reiner Road following major truck routes to and from <br /> destination job sites. <br /> i. Proposed phasing plan. <br /> The Northern Expansion Area will be completed in one phase extending the north wall north to <br /> extraction limits. Topsoil will be used to create a screening berm around the perimeter of the site for <br /> screening and storm water/snow melt runoff control. Overburden material will be stockpiled on-site <br /> for use during reclamation.A portion of the area will be used for screening and stockpiling material. <br /> The Non-conforming(Main Pit)area will continue to be used to process and stockpile aggregate for <br /> use. <br /> The South Pit area will be used to stock pile and process material. <br /> j. Types, quantities, and frequency of use of equipment to extract,process and haul. <br /> Equipment used includes equipment used for stripping, drilling,blasting, crushing,washing, <br /> stockpiling, loading, scaling, and loading materials. Said equipment includes,but not limited to, <br /> Conditional Use Permit—Mineral Extraction Updated December 9,2016 NE 1/4 of the NE 1/4 Sec.,26,T8N,RI OE <br /> Madison Crushing&Excavating.,Inc.
