2.2.7 Loma Rail Loadout -Description of Operation <br />• <br />Lodestar leases a rail loadout site of approximately 5.57 acres located at Loma, Colorado in <br />Mesa County. The entire lease area is the Permit Area. This area lies totally within the D&GRW <br />right-of-way and was used as a rail loading site prior to the lease. The disturbed area is <br />approximately 2.91 acres. The lease varies in width from 69 to 80 feet and is approximately 3,210 <br />feet long as shown in Figure 2.2-15. <br />Current use is a coal storage and loadout facility. The reclamation of the Loma Loadout and <br />interim reclamation at the Munger mine bench will be completed by November 1, 2001. <br />Surface Water Controls <br />The Loma rail siding activity as described is isolated from all surface water runoff other than <br />direct precipitation. A small flow of irrigation wastewater is passed through the permit area in the <br />northwest section of the site. Irrigation return water is passed beneath the D&RGW main line and <br />spur tracks in two culverts located as shown in Figure 2.2-15. Flow from the culvert located furthest <br />• to the northwest is the collected in a ditch paralleling the spur track. A culvert will be installed as <br />shown which will carry the flow to the opposite side of the permit area to the collector ditch as <br />shown. Flow from this ditch will merge with that from the third culvert where it will exit the permit <br />area. The water eventually enters another irrigation return ditch to the southwest. All irrigation <br />return water will be isolated from the loading operation with these measures. <br />As noted, the only other flow associated with the loadout site is that resulting from direct <br />precipitation. The general grade of the site is along it's axis towards the southeast. Berms will <br />constructed along the east and southwest sides of the site, to contain any direct precipitation. A <br />typical berm section is shown on Figure 2.2-15. Field evaluation during earth work may result in <br />adjustment to this typical section. A berm will also be constructed at the northwest end of the coal <br />storage and loading area which will isolate it from the rest of the permit area. Any runoff from <br />precipitation events which is not absorbed will flow to the southeast comer of the site which will act <br />as an evaporation area. <br />r <br />/t~3~0 ~ <br />M~ Page 2.2 - 14 2001 <br />
