The profile grade for the spur was designed to follow the natural terrain, and to minimize <br />excavation and embankment requirements and maintain the required train operation conditions. <br />Figure 12-2 (taken from Permit C-80-003 application package, Volume I, Exhibit M) shows the <br />railroad spur profile and typical cross-section. <br />The excavation and embanlment slopes are 2H:1V or flatter. Prior to excavation and <br />embankment, the topsoil was removed and stockpiled for later use in the reclamation of the <br />railroad. The topsoil stockpile was seeded to prevent erosion. <br />The railroad spur crosses Walker Ditch (a privately-owned irrigation ditch) and the loop <br />track crosses Dry Creek at two locations. Each of the crossings are made by using culverts. <br />The loop track is long enough to handle a unit train consisting of 77 cars. The railroad <br />spur and loop are designed to provide enough trackage so that County Road 37 will not be <br />blocked during unloading operations. <br />The permit boundary (i.e., the rail spur} crosses two public roads - U.S. Highway 90 and <br />Routt County Road 37, as well as one private road that accesses a parcel of property in the <br />E1/2 of Section 10 (see Exhibit 3-1). To assure that the interests of the public and <br />landowners are protected in accordance with Rule 2.05.3(3)(c)(vJ, there are existing grade- <br />crossing traffic control devices at Highway 40 (railroad crossing signs, flashing lights and <br />gates) and Routt County Road 37 (railroad crossing signs and flashing lights). As part of • <br />the Loadout's Routt County Special Use Permit, HGTI committed to updating the two public <br />road crossing with current, state-of-the-art traffic control (warning) devices to meet <br />Public Utility Commission and Colorado Department of Transportation standards. New flashing <br />lights with gates will be installed at the Routt County Road 37 crossing. In addition, <br />limited-access signage will be installed at the private road crossing. Furthermore, as <br />noted above, the train lengths are limited to assure that the county road crossing is not <br />blocked during unloading operations. <br />Support Facilities (2,000,000 Ton Train Unloading and Truck Loading System) <br />The facilities area will be modified to accommodate the proposed train unloading and truck <br />lcading system. The unloading system is similar to the approved unloading design (TR-O5, <br />May 2000), however, there are several modifications. Some of the existing facilities will <br />be refurbished and used with this proposed coal handling system. Others will be demolished <br />and properly disposed. Under this operations plan, the facilitywill no longer be capable <br />of receiving raw run-of-mine coal by haul truck and loading the coal on trains for market <br />delivery. <br />Table 12-3, Hayden Gulch Loadout Facilities Summary, describes the structures for the . <br />2,000,000 ton per year operation. The table describes existing structures that will be <br />incorporated into the new operation plan, new structures that will be constructed, as well <br />TR-07 19 Revised 06/06 <br />
