Keffelew, Environmental Protection Specialist <br />CC: Division 2 Office; District 14 Water Commissioner <br />FROM: Melissa A. Peterson, P.EjAf <br />RE: Colorado Backhole Service, File No. M-2009-074 f <br />Operator: Colorado Backhole Service <br />Section 6, Twp 21 S, Rng 63W, 6th P.M., Pueblo County <br />CONDITIONS FOR APPROVAL <br />® The proposed operation does not anticipate exposing groundwater. Therefore, exposure of ground <br />water must not occur during or after mining operations. If stormwater is contained on-site, it must <br />infiltrate into the ground or be released to the natural stream system within 72 hours, or all work <br />must cease until a substitute water supply plan, or augmentation plan approved by water court, is <br />obtained. Reclamation plans must ensure water will not be retained onsite for more than 72 hours <br />unless an augmentation plan approved by water court is obtained. <br />® Other: Water for dust suppression must be purchased from an approved supplier. <br />COMMENTS: Excavation in the pit will be above the water table. Storm water will be diverted to its <br />natural runoff pattern. Any water retained in the pit is anticipated to percolate into the pit floor. <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 <br />www.water.state.co.us
