INTROC)UCI'ION - FASI'IIW SDCI'ION <br />• The Mine Fhtrance Haul Road (MIIiR) was designed and constructed during <br />1989 and 1990 in preparation for coal haulage in 1990 from the Seneca II-W <br />Mine area. The MII-IF2-Eastern Section only modified the existing access <br />road by increasing the width of the road. The alignment was modified by <br />MR 13. Tables 1 and 2 contain the as-built culvert and ditch design <br />summaries, respectively. The as-built calculations for ditches and <br />culverts are contained in Attachments 13-6 and 13-7, respectively. This <br />certification covers approximately 410 feet (0.08 miles) of the <br />MII-II2-Eastern Section. <br />CONSTRUCTION SUMMARY - EASTERN SECTION <br />In accordance with Rule 4, Part 4.03.1(1)(d) of the Rules and Regulations <br />of the Colorado Mined Land Reclamation Board pursuant to the Colorado <br />Surface Coal Mining Reclamation Act 34-33-101 et. seq., 2, Ronald J. <br />Gehrke, hereby certify that the construction of the MII-Il2-Eastern Section <br />was inspected by me.
