CONDITIONS FOR APPROVAL
® The proposed operation does no[ anticipate exposing groundwater. Therefore, exposure of ground water must not
occur during or after mining operations.
^ The proposed operation will consume ground water by ^evaporation, ^dust control, ^reclamation, ^water
removed in the mined product, ^processing, ^other:
Prior to initiation of these uses of ground water, the applicant will need to obtain either a gravel pit or other type
of well pernilt, as applicable. Prior to obtaining a permit, an approved water supply plan or decreed plan for
augmentation is required.
^ Prior to approving a well permit, the applicant must conduct a field inspection of the site and document the
locations of all wells within 600 feet mile of [he petmit area. The applicant must then obtain a waiver of
objection from all well owners with wells within 600 feet of the pemlit area or contact this office regarding the
600 foot spacing notification hearing process.
® The proposed operation may have potential impact on existing water rights near the project location. Please
provide evidence that the proposed project will not alter or impact the historic operation of existing water rights.
^ The applicant has indicated plans to use other water for: uses at the permit site, storage in the excavated
azea(s). The applicant will need to provide evidence to this office that the water is pertnitted or decreed for such
uses.
^ Other:
COMMENTS: The applicant claims that groundwater will not be exposed or consumed in the operation, however it
appears from the records of recent activity related to this pemtit that groundwater may have been exposed or consumed.
The applicant must be required to obtain a well pemlit and substitute supply plan or decreed plan for augmentation if
any further exposure is possible. The applicant also indicated plans to construct a combination settling pond/stormwater
retention pond on the site, to remain after mining is completed. If stormwater is not diverted or captured in priority,
Colorado water law requires it to be released, or replacement for evaporation will be required of the
impounder/operator/owner of the gravel pit. The State Engineer's current policy requires that all impounded water be
released to the stream system within a maximum of 72 hours after impoundment. Unless captured in priority,
impounded water may not be used for any purpose except as approved under a water supply plan or decreed plan for
augmentation.
