Exhibit G WATER INFORMATION. <br />GEI Consultants, Inc. prepared the attached engineering <br />analysis of the hydrologic balance impacts due to lining the lake <br />areas. It discusses the up gradient and down gradient impacts <br />associated with the slurry wall. As can be seen they say that <br />they would expect to find a two foot increase in the up gradient <br />ground water level and little or no impact along the down gradi- <br />ent side due to the close proximity of the South Platte River. <br />They also say the this will create minimal impacts to the ground <br />water table that can be mitigated. This water table increase <br />would be along the south side of Sharkey's Lake and the mounding <br />would be contained entirely on the mine site. The report sug- <br />gests putting a surface ditch along the south side of Sharkey's <br />Lake will alleviate the increased water buildup by diverting the <br />water around the lined area. Platte Sand & Gravel LLC will <br />follow their recommendation. <br />4 <br />
