<br />• EXHIBIT G WATER INFORI,1ATION <br />INTRODUCTION <br />The proposed operation is not expected to directly affect surface or groundwater. Surface <br />drainages on site represent the extreme upper reaches of minor ephemeral drainages. The <br />operation is planned for no surface discharge to existing natural drainages. An NPDES permit <br />will not be required. Surface runoff will be controlled on-site as previously described in the <br />mine and reclamation plan. <br />Two Glitches that cross the property, Upper McKay and Church Ditches, will remain <br />undisturbed. Runoff from the operation will not be allowed to drain into the ditches. <br />Discontinuous shallow groundwater may exist on the property. Minor pi[ inflows may occur. <br />Rccha:ge to this groundwater is from precipitation infiltration as the gravel deposit is above <br />and not hydrologically connected to any bedrock aquifers. This limited groundwater is no[ <br />used as a water supply on or adjacent to the property and there are no drinking water wells in <br />[he immediate vicinity. <br />Fresh •x•ater and settling ponds on the site will be clay lined so that ver}' limited seepage will <br />occur. The fresh water and settling pond water will contain no contaminants. Non-hazardous <br />• flocculants ma}' be used to improve sediment deposition. The settling ponds will contain a high <br />suspended sediment load. <br />11'ATER REQUIREI.1ENTS <br />The project is estimated to require approximately 5,800 gallons per minute (10%of that, or 580 <br />gallons per minute, is the estimated consumptive use). Most of this will be supplied b}' the <br />return of recycled process water from the settling ponds. Evaporation and retention losses will <br />rcquirt: some replacement. Raw water supply will be from the McKay reservoir (Rocky Flats <br />Lake) south of the property. <br />GENERAL SETTING <br />The proposed mine operation is located in the Coal Creek Basin which is part oC the South <br />Platte River drainage system. The area is drained by intermittent, northeast-flowing streams. <br />The project is located in the Rock Creek Basin a subbasin to Coal Creek. Two irrigation <br />ditches also traverse the site. The Upper McKay and Church Ditches flow southwest to <br />northeast from the southern portion of the site. <br />n <br />U <br />
