A valid well permit must be obtained for any exposure of ground water occurring during or after <br />mining operations and for any ground water uses. According to the applicant's submittal, water is <br />expected to be encountered and an augmentation plan has been submitted to the State Engineer and <br />local water court to allow for evaporative and consumptive use. According to the applicant, water <br />consumption by the mining operation will be limited to dust suppression and operational purposes at the <br />permit site. The operator intends to mine this site as a wet pit and will not discharge ground water from <br />the site. The applicant must apply for a well permit pursuant to the approved augmentation plan. <br />COMMENTS: <br />This office has no objections to the Consideration of 112c Construction Materials Reclamation Permit <br />Application so long as the site operates under a valid well permit for any ground water exposure or use <br />The applicant may contact the State Engineer's Office with any questions. <br />Cc: Division 4 Engineer <br />District 40 Water Commissioner <br />of to <br />1313 Sherman Street, Room 821, Denver, CO 800203 P 303.866.3581 ti <br />John W.
