C~ , ~: VIII. ldater Rights and Reo7 ~ n~ cro~r..~ ...a r. r e -18- - Rules 2.04.7(3). 2 Page 4-15 of Volume I of the application contains information on water rights in the vicinity of the operation. The applicant states that no ground water rights have been adjudicated within a three mile radius of the permit area. No information is supplied with respect to surface water rights. The applicant has secured rights for 10 cfs discharge from the Mack Pumping Pipeline for use at the mine. Total consumptive use projected for the mine is less than .07 cfs (see page 2-27). The operation is in compliance with the requirements of this'section. IX.. Probable Hydrologic Consequences and Cumulative Impacts Assessment - Rules 2.05.6(3) and 2.07.6(2)(c) The McClane Canyon Pline will have very limited impact on the surface and ground eater hydrology of the hgdrologically adjacent area. Any impacts on surface eater quantity and quality will be limited due to the small area of the drainage impacted by the operation. Because the operation may only exist for this permit term, impacts will also be limited with respect to time. After the area is reclaimed, the hydrologic characteristics of the alluvial system will be restored. The surface disturbance in McClane Canyon will have very. little impact on water quantity and quality of East Sali Creek. Only .Oli. of the drainage area contributing to the flow at the confluence of McClane Canyon and East Salt Creek will be affected by the operation. The disturbance of less than ]X of the contributing drainage area is insignificant in'itself and will have a minimal impact on the hydologic characteristics of the East Salt ' Creek system. Runoff contained within the sedimentation system will be insignificant with respect to flow is East Salt Creek. Water will be retained within the sedimentation pond until it meets NPDES and Mined Land Reclamation effluent standards. Impacts on ground water could occur in two ways; 1) through the effect of the mine workings on geologic ground water and 2) through the effect of the surface disturbance on alluvial ground water in East Salt Creek. In either, case, the mine is not expected to have a significant effect on ground water quantity or quality. Drilling in and around the permit area has indicated that there is little water associated with strata within or near the mine zone. The only significant water bearing unit encountered lies approximately 200 Eeet below the coal. A saturated area has been located in advance of the mine and outside of the permit boundary where the coal being mined does contain water. Since no water should be experienced by the mine during this permit term, no problems with respect to diminution of the quantity of water in any ground water aquifer is anticipated.
