• Construction Summary: C-3 Haul Road. In accordance with Rule 4, Part <br />4.03.1(1)(d) of the Rules and Regulations of the Colorado Mined Land <br />Reclamatiun Board pursuant to the Colorado Surface Coal Mining <br />Reclamation Act 34-33-101 et.seq., I, James Gary Schlenvogt, hereby <br />certify that the C-3 Haul Road was inspected by myself. I, James Gary <br />Schlenvogt, am a 1975 graduate in civil engineering and I have been a <br />Registered Professional Engineer in Colorado since October 17, 1980. On <br />April 6 and 7, 1988, I was on site and inspected this structure. <br />The C-3 Haul Road is a middle haul road ramp in the Wolf Creek pit area, <br />located between the A-2 and C-2 Haul Roads (see Exhibit 12-1, Operations <br />Plan). This certification covers approximately 350 feet of the haul <br />road. This haul road was completed in 1987. The road was cut basically <br />on bedrock grade after the topsoil was removed. <br />The purpose of my inspection and certification was to ensure proper <br />construction of the C-3 Haul Road and to satisfy the requirements of <br />• Rule 4.03.1(1)(d) of the Colorado Mined Land Reclamation Division. <br />To the best of my knowledge, based upon my professional expertise and to <br />the extent possible, this haul rcad at the Seneca Mine was constructed <br />in accordance with the prudent state-of-the-art of earthen construction. <br />Further, the structure was constructed in compliance with the approved <br />design, to the extent possible, as specified in Tab 12 and Exhibits <br />12-47 and 12-48 of Peabody Coal Company's mine permit. Sediment and <br />runoff control is provided by Sedimentation Pond 002. The haul road <br />location and horizontal alignment is shown on Exhibit 12-1, Operations <br />Plan. The vertical alignment is shown on Figure 1, "C-3 Haul <br />Road-As-Built". The road width is adequate for the anticipated volume <br />of traffic in this pit area (see Er.hibit 7-14). <br />The road was constructed on bedrock grade after topsoil was removed; <br />therefore, no density tests or proctors were required; however, the road <br />appears to be adequately maintained by the mine's motor grader and the <br />• road appears to be compacted from the routing of heavy construction <br />equipment and coal haulage over the road. The road structure appears to <br />12-7-1 Revised .05/16/88 <br />
