• Haul Road F was designed and constructed during 1990 in preparation for <br />coal haulage in 1990 from the Seneca II-W Mine area. All salvageable <br />topsoil was removed from the disturbance area and stockpiled. Table 13-5 <br />in Tab 13 contains the as-built culvert design summaries. The typical <br />ditch sections are depicted on Exhibit 13-10. The as-built ditch and <br />culvert calculations are contained in Attachme~tts 13-6 and 13-7, <br />respectively. This certification covers approximately 240 feet of Haul <br />Road F which is outside of the m " disturbance limits. <br />In accordance with Rule 4, Part 4.03.1(1)(d) of the Rules and R~ulations <br />of the Colorado Mined Land Reclamation Board pursuant to the Colorado <br />Surface Coal Mining Reclamation Act 34-33-101 et. seq., I, Ronald J. <br />C~hrke, hereby certify that the construction of Haul Road F was inspected <br />by me. I, Ronald J. Gehrke, am a 1977 graduate in civil engineering and I <br />have been a Registered Professional Engineer in Colorado since November <br />22, 1982. I visited the site on numerous occasions during the <br />• construction period. <br />On May 21 and 22, 1990, I visited the construction site and observed <br />topsoil removal for Haul Road F and placement of fill material according <br />to the approved design and specifications. <br />I visited the construction site again on June 19 to 21, 1990, July 26 and <br />27, 1990, and September 5, 1990 and observed plaoanent of culverts and of <br />fill material. These activities were conducted in accordance with the <br />prudent state-of-the-art earthen construction. On November 20 and 21, <br />1990, I inspected Haul Road F and construction was Meted except for <br />some additional subbase material and the surface material to be placed. I <br />inspected Haul Road F on May 7, 1991 to check the drainage control and <br />horizontal and vertical alignment. <br /> The purpose of my inspections and certification was to ensure proper <br /> construction of Haul Road F and to satisfy the requirements of Rule <br />• 4.03.1(1)(d) of the Colorado Mined Land Reclamation Divison. <br />Revised 09/13/91 <br />~~ \~ <br />
