for this additional culvert, although the drainage area has been greatly reduced. The location of the culverts <br />(E-2-D and E-2-E) are shown on Map 24, Surface Facilities. <br />Culvert Extension <br />Both culverts D-3-A and D-3-A(1) are located under the junction of Haul Road B, Haul Road C, and the <br />railroad. They are presently 48 inches in diameter, 40 feet in length and are used to direct the flow of Foidel <br />Creek under these travel routes. <br />It is proposed to extend each of these culverts by 80 feet on the East Side and 20 feet on the West Side of the <br />crossing. All calculations have been considered in conjunction with a 100-year Flood, and the two extended <br />culverts combined would be able to handle this excessive water (See Exhibit 8M). Approximately 75 cubic <br />yards of road base and 300 yards of spoil material will be used to cover the culvert extensions. Rock checks <br />will then be placed across the new extensions, both on the West and East Side of the crossing. Alltravel is to <br />remain on the originally established crossing. <br />The Corps of Engineers has approved the plans for the culvert extensions based on the `Nationwide Permit <br />3'. <br />The location of the culverts (D-3-A and D-3-A(I)) is shown on the Surface Facilities Map (Map 24). All of <br />the proposed extensions of these culverts will be removed when no longer needed. <br />Refuse Pile Haulroads <br />A new haul road (formally classified as an access road) for construction and utilization of the waste pile will be <br />established parallel to the eastern margin of the pile (see Map 24). The road will be designed and constructed in <br />accordance with the design requirements of Rule 4.03.2. The road surface will be approximately 20 feet wide <br />• with an overall gradient of approximately 6.5°/a The road will be constructed in accordance with the <br />specifications detailed on Figure 22, Access Road Typical Sections, and surfaced with imported gravel or other <br />suitable material. Northwest Colorado Consultants evaluated the existing road and recommended that 13 inches <br />of pitrun gravels and 5 inches of Class VI base course be used to construct the road. The materials were to be <br />placed in lifts and compacted as per the requirements or Rule 4.03.1. The road will be constructed in a staged <br />fashion from north to south with approximately 500' segments completed as necessary to maintain reasonable <br />access to the active area of the pile. Access to the waste pile will be routed around completed portions of <br />permanent diversion ditch RDA-2. Ditch crossings may be required for the temporary diversion ditch <br />established upgradient from the working area of the pile. The crossing sites will be suitably protected with <br />durable material to prevent excessive erosion or an appropriately sized culvert will be installed. Culvert sizing <br />documentation will be provided to the Division prior to installation if this option is utilized. Topsoil salvaged <br />from cons[rnction ofthe access road will be stored in topsoil stockpile SB12 located adjacent to the construction <br />site. <br />In order to facilitate vehicle movement through the refuse pile a short haulroad segment will be constructed off <br />of the eastern nose of the refuse pile. The design and certification of the is presented in Exhibit 25F. The <br />culvert sizing for the road was previously approved in MR 9Cr 140. <br />[R. Access Roads <br />Fish Creek Borehole Dewaterim¢ Site <br />The access road to the Fish Creek Borehole Site is approximately 9,000 feet in length. The location <br />of the site and the access road is shown on Map 26, Fish Creek Borehole Area and Access Road. <br />• The existing road was designed so that construction, maintenance, and post mining condition of the <br />APP 1~,~@~>r~ APP 1 4 [000 <br />TR 00-35 2.05-70 01/14/00 <br />
