Exhibit G Water Information (cont) <br /> tion return flow ditches surrounding the lined area. These <br /> existing water features will serve to regulate and balance <br /> groundwater elevations in the alluvium adjacent to the sealed <br /> pits . The GWM suggests that once the groundwater reaches the <br /> maximum predicted levels it will stabilize and the corridors left <br /> through and around the liners will allow water to pass around the <br /> liners . <br /> The operator does not anticipate any long-term post-reclama- <br /> tion ground water depletions, but if there are any, they would be <br /> replaced through a Colorado Water Court approved Plan of Augmen- <br /> tation. <br /> L.G. Everist, Inc. expects that prior to competition of the <br /> reservoirs a local government agency will purchase the storage <br /> rights and may begin final construction on the reservoirs . As <br /> water storage reservoirs are completed, they will be turned over <br /> to the purchaser for further development to complete the final <br /> features needed for developed water storage reservoirs . L.G. <br /> Everist will submit Technical Revisions to the DRMS if the pur- <br /> chaser makes changes prior to L.G. Everist receiving final recla- <br /> mation approval and acreage releases from the Division. <br /> Water Quality <br /> The attached report prepared by Molen Associates explains <br /> the plan for collecting the necessary background water quality <br /> information of the permit area. Included is a list of the chemi- <br /> cals to be tested for and their frequency. This plan includes <br /> installing 6-7 additional monitoring wells around the mine and <br /> use 4 existing wells that lay outside the proposed slurry walls <br /> to collect the data needed for 5 quarters prior to mining and <br /> yearly testing as needed. Once the 5 quarter samples are col- <br /> lected and analyzed a Technical Revision may be filed to reduce <br /> the required monitoring list for the life of the mine. <br /> Discharge Permits Surface Water Management <br /> When necessary, ground water will be pumped and discharged <br /> from the West Farm Reservoirs mine under a CDPS Permit which the <br /> operator will obtain from the Colorado Department of Public <br /> Health and Environment, Water Quality Control Division (CDPHE- <br /> WQCD) . This permit will remain active during the life of the <br /> mine. The discharge points may change as mining progresses and <br /> all necessary changes will be submitted to the WQCD for modifica- <br /> tions to the discharge points . <br /> Runoff from disturbed areas will be managed and controlled <br /> to protect against pollution, of either surface or groundwater <br /> through the implementation best management practices which in- <br /> clude sloping disturbed areas inward toward the site, vegetating <br /> L.G.
