coal mining in the general area on the hydrologic balance and to <br />make a finding (as discussed in Section A of this documen*_) that the <br />operations proposed in the permit application have been designed to <br />prevent material damage to the hydrologic balance outside of the <br />proposed permit area. This section of the findings document is <br />divided into the following subsections: Description of the <br />Hydrologic Environment; Probable Hydrologic Consequences of the <br />Terror Creek Loadout; and Summary and Findings. A separate <br />Cumulative Hydrologic Zmpact Study (CH IS) is available for review at <br />the Division of Minerals and Geology. The CHIS filed at the <br />Division, assesses the projected cumulative hydrologic impacts for <br />all anticipated mining operations in the general area of Che Terror <br />Creek Loadout on the North Fork of the Gunnison River Valley. <br />1. Description of the Hydrologic Environment <br />a. Regional Geology <br />For information regarding the geology of the site, refer <br />back to the section entitled Description of the Environment, <br />Geology. <br />b. Groundwater <br />For information regarding the groundwater of the site, refer <br />back to the section entitled Description of the Environment, <br />Hydrologic Balance. <br />c. Surface Water <br />For information regarding the surface water of the site, <br />refer back to the section entitled Description of the <br />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 <br />Terror Creek Loadout, due to the lack of occurrence of <br />groundwater within the immediate area to be affected by the <br />operation. The operation is located on colluvial material <br />significantly above the elevation of the North Fork of the <br />Gunnison River. This colluvium appears to be in direct <br />hydrologic communication with the North Fork alluvial <br />aquifer. Only minor amounts of groundwater can be expected <br />above the piezometric surface which coincides with the North <br />Fork. Information presented by the applicant with respect <br />to a privately owned water well south of the permit area <br />indicates that water is not encountered until the river <br />elevation is reached. Operations at the Terror Creek <br />facility will not intersect any groundwater within the <br />colluvial material due to limited excavation planned for the <br />Terror Creek Loadout Page 14 <br />
