Sherman <br />Executive Director <br />(Vacant) <br />State Engineer <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 />^ The proposed operation will consume ground water by: ^ evaporation, ^ dust control, <br />^ reclamation, ®wter removed in the mined product, ^ processing, ^ other:.drilling <br />Prior to initiation of these uses of ground water, the applicant will need to obtain either a gravel pit <br />or other type of well permit, as applicable. <br />^ Prior to approving a well permit, the applicant must conduct a field inspection of the site and <br />document the locations of all wells within 600 feet of the permit area. The applicant must then <br />obtain a waiver of objection from all well owners with wells within 600 feet of the permit area or <br />request a hearing before the State Engineer. <br />^ Other: <br />COMMENTS: The applicant states that a mining contractor will provide water to the site. The mining <br />contractor must obtain water from a legal source such as a municipality. <br />
