BOX 550 <br />ROCKY FORD, COLORADO 81067 <br />(303) 254-7464 <br />Dear Mr. Schmieding, <br />Re Valco, Inc. - Canon City East Pit - MLR File No. 77-559 <br />Division of Water Resources Memorandum of February 9, 1978 <br />On February 17 we received a copy of the subject memorandum. <br />We appreciate your forwarding it to us. <br />Living and working in the Arkansas Valley as we do at Valco, <br />we are aware of water problems in the Valley. 3fuch of our <br />product goes into concrete irrigation ditches and other water <br />facilities. In our operating area throughout the Valley we <br />continually attempt to conserve water and minimize the <br />effects of our operations on the hydrologic balance. We <br />feel that we are doing a good job in this respect. <br />Dr. Danielson's staff may have missed a few items in review- <br />ing our application. This is quite understandable in light <br />of the number of applications being processed at this time. <br />Our comments with respect to the items delineated in the <br />memorandum follow. They are numbered to conform to the para- <br />graph numbers in the memorandum. <br />1. We were not aware that "the applicant must calculate <br />the cone of depression created by dewatering in order'to <br />determine the potential effects of dewatering on nearby wells." <br />Our well in the plant site area (see map Exhibit C or map <br />Exhibit C-1) is the closest well and is not affected by the <br />amount of dewatering being done. As far as we know, it is the <br />only well anywhere near the pit. This mining operation has <br />been in progress since 1972. It seems likely that if any <br />well in the area was being affected, we would have been <br />advised by now. <br />2. We assume the DWR is referring to augmentation. We <br />do not believe they have considered the amount of open water <br />existing at the present time, the work Valco has done and <br />LAMAR CANON CITY PUEBLO <br />
