Therefore, exposure of ground <br />water must not occur during or after mining operations. <br />? The proposed operation will consume ground water by: ? evaporation, ? dust control, ? <br />reclamation, ? water removed in the mined product, ? processing, ? other: <br />Prior to initiation of these uses of ground water, the applicant will need to obtain either a gravel pit or <br />other type of well permit, as applicable. However, prior to obtaining a permit, an approved water <br />supply plan or decreed plan for augmentation is required in overappropriated areas. Currently this <br />location is not considered overappropriated, however, if this area becomes overappropriated, <br />augmentation will be required. This proposed pit is located in a critical stream system. <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 obtain <br />a waiver of objection from all well owners with wells within 600 feet of the permit area or request a <br />hearing before the State Engineer. <br />?N The proposed operation may have potential impact on existing water rights near the project location. <br />Please provide evidence that the proposed project will not alter or impact the historic operation of <br />existing water rights. <br />? The applicant has indicated plans to use other water for: ?¦ uses at the permit site, ? storage in the <br />excavated area(s), ? other: . The applicant will need to provide evidence to this office that <br />the water is permitted, decreed, or leased for such uses. <br />0 Other: if storm water is not diverted or captured in priority, Colorado Water Law requires it to be <br />released, or replacement for evaporation will be required of the impounder/operator/owner of the <br />gravel pit. The State Engineer's current policy requires that all impounded water be released to the <br />stream system within a maximum of 72 hours after impoundment. Any exposed ground water must <br />be backfilled immediately until a well permit issued pursuant to CRS 37-90-137(2), allowing the <br />exposure of ground water in a pit, is obtained from the State Engineer. <br />COMMENTS/NOTES:
