the Terror Creek Loadout; and Summary and Findings. A separate Cumulative <br />Hydrologic Impact Study (CHIS) is available for review at the Division of Minerals <br />and Geology. The CHIS filed at the Division, assesses the projected cumulative <br />hydrologic impacts for all anticipated mining operations in the general azea of the <br />Terror Creek Loadout on the North Fork of the Gunnison River Valley. <br />Description of the Hydrologic Environment <br />a. Regional Geology <br />For information regarding the geology of the site, refer back to the section <br />entitled Description of the Environment, Geology. <br />b. Groundwater <br />For information regazding the groundwater of the site, refer back to the <br />section entitled Description of the Environment, Hydrologic Balance. <br />c. Surface Water <br />For information regazding the surface water of the site, refer back to the <br />section entitled Description of the Environment, Hydrologic Balance. <br />2. Probable Hydrologic Consequences <br />a. Groundwater Effects and Mitigation <br />There is expected to be no impacts to groundwater by the Terror Creek <br />Loadout, due to the lack of occurrence of groundwater within the <br />immediate azea to be affected by the operation. The operation is located on <br />colluvial material significantly above the elevation ofthe North Fork ofthe <br />Gunnison River. This colluvium appears to be in direct hydrologic <br />communication with the North Fork alluvial aquifer. Only minor amounts <br />of groundwater can be expected above the piezometric surface which <br />coincides with the North Fork. Information presented by the applicant <br />with respect to a privately owned water well south of the permit azea <br />indicates that water is not encountered until the river elevation is reached. <br />Operations at the Terror Creek facility will not intersect any groundwater <br />within the colluvial material due to limited excavation planned for the <br />permit area. Excavation associated with the ladout pad was completed to <br />approximately 20 feet below ground surface and no groundwater was <br />encountered. No springs or seeps have been identified along the colluvial <br />deposit in the vicinity of the permit azea. <br />Because no further surface disturbance is proposed, there is no potential <br />for significant impacts to groundwater quantity in the azea. There is avery <br />slight potential for quality of water in the alluvial aquifer immediately <br />14 <br />
