• _14- ` is and Reolacement - :rules 2.0=:.7(3), 2.05.6(3)(a)(ii), cl. and 4.05.15 (rnn'tl Page 4-15 of volume I of the applicatier, contains information on water rights in the vicinity of the operation. the applicant states that no ground water rights have been adjucicated within a threE mile radius of the permit area. ]:o ir.formatien is supplied with respect to surface water rights. The applicant has secured rights for 10 cfs discharge from the Piack Fumping Pipeline for use at the mine. Total cor.surptive usE projected for the mine is less than .07 cfs (see page 2-27). The operation is in compliance with the reeuirements of this section. I.l'. Probable Hydrologic Consequences ans Cumulative Impacts Assessment - es The ?•fcClane Cannon Paine will hacE very limited impact on the surface and ground water hydrolog_r of the hydrologically adjacent area. Psy impacts on surface water quantity and quality will bE limited due to the small area of the drainage impacted b}• the operation. Eecause the operation. may only er:ist fen this permit term, i*~pacts trill also be limited c;ith respect to time. After the area is reclaimec, the hydrologic characteristics of the alluvial system will be restored. The surface disturbance in PfcClane Cam•cn will have very little impact en water quantity and quality of East Salt Cree}:. Only .Ol% of the drainage area contributing to the flow at the cor.fiuence of PfcClane Canyon and East Salt Creek eai11 be affected by the operation. The disturbance of less than 1'~ 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 trill be insignificant with respect to floa• in East Salt Creek. Eater will be retained within the sedimentation pond until it meets ?~~DES and Piir.ed Land Reclamation effluent standards. Impacts on ground water could occur in tcro ua.•s; 1) through the effect of the mine workings on geologic ground water and ?) through the effect of the surfacE disturbance on alluvial ground water in ~ast Salt CreeY.. In either case, the sane is not expected to have a significa.^.t e "_ect en ground water quantity or quality. Drilling ir. and around the permit area ias 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 feet below the coal. A saturated area has been locates it advance of the mine and outside cf the permit boundary where the coal being mined does contain water. Since no water should be experienced b•_ the minE during this permit term, nc problems with respect to diminution o` the euantity of water in an}~ ground water aquifer is anticipated.
