~J <br />EXHIBIT G -WATER INFORMATION <br />Overview <br />~ks and Gesso, LLC <br />This section describes the existing water features in and nearby the proposed mining <br />permit area, potential impacts on water resources due to mining, and water requirements <br />for the project. <br />Local surface water features in the vicinity of the project are shown on Exhibit B, Index <br />Map and on Exhibit C-1, Man-Made Features. A Gravel Well Permit and Temporary <br />Substitute Supply Plan will be submitted to the Colorado State Engineer at the Division <br />of Water Resour__ ce_~apptaual.-- <br />Surface Water <br />The nearest major watercourse is the St. Vrain Creek, which flows approximately one- <br />half mile from the northwest corner of the site. Water collected from excavation will be <br />clarified in the collection ponds and used for on-site operations. Prior to any discharge <br />activity to the St. Vrain Creek, the Operator will obtain a CDPS Permit and permission <br />from the ditch company to allow the use of their ditch to convey de-watering flows. <br />Groundwater <br />Wells located within 600 feet of the permit boundary for the site are shown in Exhibit C- <br />1. The wells listed as being within 600 feet of the permit boundary are all alluvial wells. <br />Domestic water is supplied to the area by the Central Colorado Water Conservancy <br />District via a water main running down Weld County Road 26. <br />Mining of the proposed excavation area of the permit will be by adry-mining method, <br />necessitating the exposure of groundwater on the site. Dewatering operations will begin <br />prior to material excavation, and will be collected in an on-site pond system located in <br />the southern section of the site. Mining will expose approximately 8.0 acres for the first <br />year and 8.3 additional surface acres the second year and will thereafter steadily <br />increase total exposed acres by approximately 8.0 surface acres per year for the <br />duration of the operation. <br />Lohmann Sand and Gravel Mine.DMG.112 <br />L.G.
