HGTI conducted a survey of access road HGLF-AR1 during May 2006. The survey data were used <br />to develop a profile of the existing conditions. The profile is presented in Appendix 12-5 <br />as Appendix 12-SC, Facilities Area Access Road Plan and Profile. This exhibit has been <br />prepared in accordance with Rule 4.03.2(1)(f)(ii), which allows a relevant showing in lieu <br />of certification of design and construction for roads constructed prior to August 1994. As <br />such, the certification on Exhibit 12-SC only pertains to the existing conditions. HGTI <br />assumes, that because there has been no CDRMS concern or issue in any monthly compliance <br />inspection report or other permit review since 1992, the access road is in compliance with <br />the performance standards of Rule 4.03.2. <br />Light-Use Roads: One light-use road was permitted for the 7.NA3 ton/year train loadout <br />operation. The road extends from the existing Truck Dump Hopper along the south side of the <br />crusher building and then looped around the stack tube coal stockpile area. This road will <br />be removed as part of the TR-06 facilities modification - removed portions will be reclaimed <br />in accordance with the reclamation plan and seeded with Seed Mix No. 1. <br /> One light-use road will be utilized following the construction of the 2 MM ton/year coal <br /> handling facility. This light-use road will travel from haul road HGLF-HR2 to the railcar <br /> unloading hopper/radial stacker area. Drainage from the road is controlled by existing <br /> Ditches 5 and 6. The location of this light-use road is shown on Exhibit 12-2 (Revision 11, <br /> dated. 03/07. <br />Railroad Spur and Loop. The Hayden Gulch railroad spur begins approximately 0.3 miles east <br />of the easterly city limits of Hayden, Colorado. As shown on Exhibit 12-1, (Revision 14, <br />dated 03/07), it extends approximately two in a southerly direction to the coal handling <br />facilities area. The approximate track length of the railroad spur and loop is 3.3 miles <br />(17, 400 linear feet) . The purpose of the railroad spur is to provide a connection to the <br />existing Union Pacific mainline track for transporting raw coal in rail cars in/out of the <br />Hayden Gulch Loadout facility. A reprint of the Railroad Spur Typical Section is shown here <br />as Figure 12-2, Profile and Section for Railroad Spur (this section was originally included <br />in the H-G Coal Company permit package [Permit C-80-003; Volume. II, Exhibit J]). <br />The railroad spur alignment begins with an eastbound connection to the Union.' Pacific <br />mainline trackage and heads in the southerly direction, crossing Highway 40 approximately <br />1,500 feet east of the Hayden, Colorado town limits. The railroad spur alignment continues <br />in a southerly direction paralleling the easterly side of Routt County Road 37, and crosses <br />the county road just prior to the beginning of the loop track. Trains enter the western <br />branch of the loop track, load/unload raw coal at the facilities area and return along the <br />eastern branch of the loop and then back out the spur to the Union Pacific connection. <br />MR-16 11 Revised 11/07 <br />
