• Water Rights Tab 1L, Protection of the Hydrologic Balance, references two surface coal mining PAP~s wh(ch contain information on surface end ground water rights edj scent to the HGT Laedou[ facility. Table 14-t (Tab 14) lists water rights that will be transferred to HGT. Tab 15, Probable Xydrologit Consequences, discusses potential impacts to water rights in She vicinity of the XGT Loadout, and concludes that no impact is likely to occur. HGT will repl ate the water supply of any owner of a water right, specific to the aquifers or stream reaches being used or potentially impacted, that is significantly effected by operations et the loadout facility. Surface and Ground Water Monitorinv Plans In addition to the mining practices designed to minimize disturbances to the hydrologic balance previously discussed, ground end surface water monitoring plans have beer developed to assess the possible impacts to the hydrologic system identified in Teb 15, Probable Hydrologic Consequences (PHC). The results of the monitoring programs have anc • will continue to be employed to support the PNC conclusions that disturbances to the hydrologic balance will be minimal end that the potential uses of the ground and surface water systems effected by the mining will not be changed. The parameters analyzed for at each monitoring site es well as monitoring frequencies ere documented in Tab 13, Hydrologic Monitoring Plan. The location of each site can be seen on Figure 13-1 (Tab 13 ). Water quality date analysis techniques that may be used to assess whether impacts to the hydrologic balance have occurred include both graphical and statistical methods. Graphical analysis techniques include trilinear end Schoeller plots end nonparametric trend plots. Stetiscicel analyses include ordinary moment statistics and nonparametr is statistics. Chronologic comparisons of instantaneous measurements of stream discharge and well water levels may also be used for impact assessments. 3
