Description of the Loadout Operation Plan Detailed information on the HG Loadout Operation Plan is found in Tab 12 of the permit application. Reclamation activities associated with the Loadout and rail loop are described in Tabs 16 - 20 and 23 of the permit document; and in Section B of this document. Construction of the Loadout and rail loop began in 1978 and coal was shipped to market from the facility until spring of 1987. Coal was again stored at the Loadout beginning late in 1992. Coal has been removed and no coal is currently (2014) stored on site. Technical Revision No. 5 (TR5), approved 24 July 2000, allowed for using the Loadout site to off load coal from incoming rail cars. Technical Revision No. 6 (TR6) provided more detail for "load -in" operations. The facilities approved in TR6 have never been constructed. The "load - in" facilities were approved to handle 2,000,000 tons of coal per year. Coal would have been hauled by truck along the TAHR to the Hayden Power Station. Prior to utilization as a "load -in" facility, HGT would have needed to construct support facilities as approved in the permit during TR6. Air emissions permits would have been required to be renewed with the Colorado Air Pollution Control Division prior to implementation of "load -in" operations. Water control systems and sediment ponds throughout the permit area were appropriate for the "load -in" operation. The existing roads would be used for the "load -in" operations with the addition of a new haul road, HGLF -HR2, previously approved under TR -06 (June 15, 2005). Hayden Gulch Terminal Inc. operated the loadout facility as discussed above, and was permitted to store up to 50,000 tons of coal at the Loadout and ship 1,000,000 tons of coal per year. In the summer /fall of 2011, HGT initiated reclamation of the facilities area. The "load -in" facilities were never constructed and the Loadout facilities were demolished and removed from the site. The affected area was graded, topsoiled and seeded. The Division granted Phase I bond release at the site during SL I. The future operations plan for the site during the next five year permit term will be based on future economic and political conditions. No additional disturbance is planned at this time. Two existing sediment ponds (and associated NPDES outfalls) act as sediment control for the runoff from the loadout area: the Truck Loop Pond (Pond A, NPDES Outfall 006) which treats the truck loop and office area and the Rail Loop Pond (Pond B, NPDES Outfall 007) which treats the coal crushing, storage and tipple areas. A system of ditches diverts freshwater around the disturbance and another system of culverts and ditches conveys water under roadways and to the sediment ponds (see Appendix 12 -4 and Exhibit 12 -2, "Surface Water Control Plan Map "). Sixteen small area exemptions are permitted for the three topsoil stockpiles (TS -1, a portion of TS -2, and TS -3) associated with the Loadout, and six topsoil stockpiles (A, C, D, E, F, and G) and one temporary waste stockpile (TWS) associated with the TAHR outside the sediment control system described above (see Appendix 12 -2 and Exhibit 9 -1). A small area exemption has been approved for the electrical substation located in the northwest corner of the facilities area. The Office/Parking Lot/Leach field has been approved as a small area exemption. The permittee has demonstrated that due to the revegetation efforts of the disturbance associated with the railroad loop, the peak settleable solids concentration is below the water quality effluent standard. Given this, the rail loop is considered as a small area exemption. Two additional areas Hayden Gulch 13 February 11, 2014
