• Aquifers Based on local conversation and past drilling, there are no known aquifers that will be penetrated. There may be some incidental drilling into the very top of the Larimie -Fox Hills depending on the depth below the lowest lignite seam and the geophysical probe used. As the formation is unconfined, there is no expectation of any artesian flow from such incidental exposure. Method of Plugging Drill Holes Holes will be sealed in compliance with 4.07.3. In general, the hole will be refilled with cuttings or other suitable media up to 10 feet from the surface. Cement will be used to fill the hole up to 3 feet from the surface and the remainder filled with drill cuttings. The hole will be marked by a 12 inch rebar buried to 2" to 3" below the surface. Transfer of Drill Holes to Surveillance Holes There are no plans to modify any of the exploratory holes into water monitoring holes or wells. 2.02.2(2)(h): Endangered or threatened species. • Wildlife Since the 2004 drill program, the area has been visited by District Wildlife representatives. This NOI will be submitted by CDMG to the Colorado Division of Wildlife for review and comment. Those comments and any correspondence will be included as Exhibit H. Cultural or Archeological Resources For the 2005 program, KMG commissioned the Colorado Historical Society to conduct a database search of eight sections along the south border of the 2004 program area. The search resulted in no additional sites beyond those identified in 2004 Exhibit F . As in 2004, the exploration drill sites will be over 1000 feet distance from any indicated cultural site. 2.02.7(1): Public availability of information. A copy of this Notice of Intent will be forwarded to the County Clerk of Elbert County upon acceptance by the Colorado Division of Minerals and Geology as a complete filing. 2.02.7(2): Confidentiality. . None of the information in this Notice of Intent is considered confidential. -11- • ESTIMATION OF RECLAMATION COSTS Exhibit G is a breakdown of the cost estimate for drill site reclamation. The assumptions made are: Drill holes filled in accordance with 4.07 and seed mix as shown in Exhibit D . No road or drill pad construction. No holes completed as monitoring wells. In summary, the reclamation cost estimate is as following:
