Exhibit C CMLRB 112 Permil Application Agile Stone Systems, Inc. • 2.0 COnC~US10I1S 1) Crossing designs were readily completed by a certified Colorado professional engineer. Likewise storm water berms and ponds and other storm related structures as well as other structures were all engineered by certified Colorado professional engineer. 2) "The impact of the Project will be to increase the water table elevation beneath the plant azea. This may also be reflected in the Dakota Group underlying the plant area, with its water table or potentiometric head increasing somewhat (2 to 5 feet), with lesser rises away from the plant. Slightly greater spring and seep flows may also result." Gilmer 3) "The increased water table elevation would be more than offset by removing irrigation from the hayfields and pastures of the adjacent ranch. This change would occur at the direction of the Division of Water Resources, as the result of its administration of junior water rights. This may lower the water table sufficiently to reduce spring flows at the river and adversely affect downgradient springs or wells." Gilmer 4) "The possible increases in potentiometric head or water table in the Dakota Group could be manifested as somewhat greater bedrock spring discharge rates to the Arkansas River, if DWR does not administer the junior irrigation rights. If • irrigation is stopped, a decline in bedrock spring flows may occur." Gilmer 5) "Hydraulic impacts to the Dakota Group and other bedrock aquifers are not expected to occur south of the Arkansas River, as the Arkansas River serves as a hydraulic boundary having nearly constant-head conditions. Furthermore, faults to the southwest, south, southeast and east of the project create structural blocks that will be hydraulically sepazate bedrock units." Gilmer 6) Changes in bedrock well production or water quality (including hydrogen sulfide presence) in the areas south of the River, and in wells producing water from bedrock aquifers structurally isolated from the Project, will be due to natural or other non-Project related factors." Gilmer Gilmer elsewhere noted that "No bedrock water will be involved in the Pazkdale Project." 7) The project will not have any impact on either the Tallahassee Creek or Arkansas River water flows or quality. Already purchased water rights will supplement any water lost due to evaporation. Water percolating through the grave] from the project will only contain sand or gravel sized material. The gravel bar will filter any possible sediment long before the water reaches the Arkansas River exactly like the sediment is filtered from the Tallahassee/Currant Creek waters passing under the gravel baz or used in flood irrigation above the Steer's spring. 4
