2 <br /> R11E. This well is estimated to be approximately 80 feet deep, constructed <br /> with about 63 feet of 0.280 inch thick steel casing. The well is fitted with <br /> a 12 gallon per minute capacity submersible pump that supplies the pressurized <br /> residential distribution plumbing through a pitless adapter style discharge. <br /> The well is located in a grassy sideyard area of the residence and it is <br /> capped with a Department approved model of a vented, vermin-proof well cap. <br /> The water supplied by this well will not be used for any of the concrete batch <br /> plant operations. <br /> Proposed Batch Plant Well Inventory <br /> DNR Permanent <br /> Well # Well # Location Civil Town, County <br /> 004 01200 NW1/4 NE1/4 S34 T9N R11E Bristol Township, Dane <br /> Proposed New Well Construction: The concrete batch plant will be sited within <br /> the limits of a limestone rock quarry that has been operated on this site. To <br /> date, the quarry operations have been limited to the northern sideslope of an <br /> existing hill, and the depth of excavation has not extended below the adjacent <br /> Quarry Road pavement surface. <br /> In constructing the batch plant supply well, approximately 350 feet of <br /> limestone bedrock formation is expected to be encountered starting at the <br /> existing ground surface. The well will consist of 200 feet of a 15 inch <br /> diameter upper enlarged drillhole that is constructed using the rotary style <br /> drilling method. In this borehole, approximately 200 feet of 10 inch <br /> diameter, 0.365 inch thick steel casing that is assembled with welded joints <br /> will be cement grouted in place. Below the casing, a 10 inch diameter open <br /> drillhole will be extended to about the 350 foot depth 'in the bedrock. <br /> This well is expected to be fitted with a 500 gallon per minute capacity <br /> submersible pump. During normal concrete batching operations, this pump is <br /> not likely to operate at more than 100 gallons per minute capacity, 12 hours a <br /> day. This pump will discharge from the well to the concrete batching <br /> operation, above ground surface, through a Department approved model of a <br /> vented, vermin-proof, sanitary style well cap. Water levels will be measured <br /> during well operation with an air line and pressure gauge and the rate of <br /> water usage will be calculated from the recorded hours of pump operation. <br /> Water will be discharged from the well to the batch plant plumbing system <br /> through a U.L. approved check valve and air vacuum relief valve. <br /> Total Batch Plant Water Usage <br /> Well Normal Water Use Maximum Water Use Period of Principal <br /> # Gallons Per Dav Gallons Per Day Operation Water Use <br /> 004 70,000 720,000 Year Round Concrete Mixing <br /> Contamination Proximity: Department files indicate that some limited waste <br /> handling operations have occurred on properties near the planned concrete <br /> batch plant site. It does not appear that any waste disposal has ever <br /> occurred on these properties. The stone quarry in which the batch plant is <br /> planned to be located has a stockpile of recycled asphalt that will be used <br /> for future road-base construction. This stockpile is not expected to have any <br /> affect on the chemical quality of the groundwater at the batch plant site. <br /> Proximal Public Utility Well: The nearest well serving a public utility is <br /> located in Sun Prairie approximately 6,500 feet southwest of the proposed <br /> batch plant supply well. <br />
