Road foundation and gravel thickness were designed based on site soil properties and the methods outlined in the U.S. Bureau of Mines Information Circular, IC 8758, "Design of Surface Mine Haulage Roads - A Manual". The Haulroad Connector is not within 100 feet of any public road right-0f--way and will not require relocation of a public mad. An 18-inch corrugated metal pipe was installed at a 2 percent grade across the Connector Haulroad to control drainage. Culvert size criteria aze included in Exhibit 8, Sediment Control Plan. The sub-grade was proof compacted and any deleterious or unsound material removed. Road fill material was hauled, spread, and compacted over the entire width of the road fill, as follows: 1) Where there was more than 5 feet of fill, the top 5 feet was compacted to 95percent of AASHTO T-180 and the remainder was compacted to 90 percent AASHTO T- 180; 2) Where there was a minimum of 3 feet of compacted road fill but less than 5 feet of fill, the entire fill was compacted to 95 percent of AASHTO T-180; and, 3) Where the road was in a cut, the roadway was over-excavated and a 3-foot minimum thickness road fill placed and compacted to 95 percent of AASHTO T-180. Moisture content and compaction were monitored during construction. The Haulroad Connector was surfaced with gravel to form a durable road surface. A 12-inch gravel base was spread and compacted to 95 percent of AASHTO T-180. '6 inches of gravel surfacing was spread and compacted to 95 percent of AASHTO T-180. The road is crowned to prevent ponding of water and surface dips have been used in conjunction with the ditches to control erosion where required. Certification for the Connecto; Haulroad is contained in Exhibit 25, As-Built Certifications of Access/Haulroadand Other Haulroads. 1TB. Haul Road B and Haul Road B Relocation (Haulroads B-1. B-2, and Drivewav) Haulroad B was originally constmcted and utilized by CYCC to link the mine lraukoads in the Eckman Park surface mined area to the mine facilities area. It was subsequently used by TCC to transport coal from the underground operations to the ROM coal stockpile and tipple. With installation of the overland conveyor belt, Haulroad B was no longer needed for normal coal haul operations, but was available for emergency coal haulage in the event that the overland conveyor was not operational. Because the overland conveyor alignment intersected Haulroad B, the road was split and partially rerouted to accommodate construction of the conveyor and subsequent construction of the coal preparation plant facilities. There aze now two segments of Haulroad B; the western segment, Haulroad B-1, extends from the Tipple 2 road intersection due south of Pond C to the point where the old Haulroad B intersects the overland conveyor corridor (southwest of the current railroad crossing); the eastern segment, Haulroad B-2 extends from the current railroad crossing to its intersection with the Haulroad Connector (just west of the 0-Entry shaft and fan building), as shown on Map 24, Surface Facilities. In addition, a minor revision added a driveway south of Haul Road B-2 and west of the prep plant to accommodate stoker truck traffic at the prep plant. The driveway enables trucks accessing the prep plant stoker stockpile to rum around after entering the mine from the main entrance east of the office. The driveway is shown on Map 24A. Centerline profiles of Haulroads B-1, B-2, and Haulroad B Driveway, and typical haukoad cross-sections are shown on Map 30, Road Profiles and Cross-Sections. Grade and pitch requirements were not exceeded in road design, construction, or relocation. The original and relocated haul road is located out of any perermial or intemuttent stream and any ephemeral stream with a drainage azea over 1 square mile. The culvert (E-2-B), under the original Haul Road B, has been relocated under the segment of the haulroad relocated during construction of Pond E. Due to minor changes in surface configuration during final site grading, the original culvert was replaced with two culverts. The additional culvert receives drainage from the segment of the prep plant azea that previously flowed back to the original Culvert E-2-B. Consistent with the original design, the additional culvert is also a 14-inch culvert, although the contributing drainage area is significantly reduced. The location of the culverts (E-2-D and E-2-E) aze shown on Map 24, Surface Facilities. Culverts D-3-A and D-3-A(1) aze located at the junction of Haukoads B-2 and C, at the railroad crossing, as shown on Map 24, Surface Facilities Map. These 48-inch, 40-foot long culverts were originally designed and sized to pass the 100-yeaz peak design flows for Foidel Creek (See Exhibit 8M) under the haulroads and railroad. Under a technical revision, these culverts were extended 80 feet on the east side and 20 feet on the west side of the railroad crossing. Appropriate approvals for the culvert extensions were also obtained from TR 05-46 2.05-68 Revised - Apri14, 2005
