Please review these comments <br /> and address any concerns identified. <br /> Colorado Division of Water Resources <br /> 1. COMMENTS: The purpose of this amendment is to add 16.2 acres to the existing 291.5 <br /> permitted acres, for a total of 307.7 permitted acres. The proposed operation will consume <br /> ground water through evaporation, dust control, reclamation, water removed with the mined <br /> product, processing, dewatering and water used for the construction of slurry wall for the West <br /> and the East cells. In accordance with Section 37-90-137(2) and (11), C.R.S., the applicant <br /> obtained a substitute water supply plan ("SWSP") and well permit no. 81342-F. Currently there <br /> are 2 acres of exposed ground water at the site, that were excavated under Tucson Resource <br /> Mine, Permit No. M-1991-140. The evaporation depletions from the 2 acres are covered by the <br /> existing SWSP approved for the Tucson South Resource Mine, Permit No. M-2004-044-140. If <br /> additional acreage will be exposed beyond what is allowed by the SWSP or the well permit no. <br /> 81342-F, the applicant will need to obtain a new SWSP and a new well permit. So long as the <br /> amended Tucson South Resource Pit is operated in accordance with an approved SWSP or <br /> approved plan for augmentation, this office has no objection to the amendment request. Any <br /> storm water runoff intercepted by this operation that is not diverted or captured in priority must <br /> infiltrate into the ground or be released to the stream system within 72 hours. Otherwise, the <br /> operator will be required to make replacements for evaporation. The applicant may contact the <br /> State Engineer's Office with any questions. <br /> Aggregate Industries—WCR,Inc <br /> 1687 Cole Blvd Suite 300 <br /> Golden,CO 80401 <br />
