In order to facilitate material storage around the weld shop area, three concrete pads, approximately 20 x 60 x 1 foot will be constructed to the east of the shop. Pipe and other hard goods will be stored on these pads. In addition, a 100 x 15 x 1 foot concrete apron will be constructed on the south side of the building to increase the utility of that storage area. When the pads and apron are no longer needed, they will be broken up and the resulting concrete rubble will be placed at the toe of the highwall. The location of the pads and apron are shown on Map 24, Surface Facilities and Fresh Water Systems. Storage /Contractor Buildings Two storage buildings were constructed for dry storage of materials. The east storage building, with dimensions of 150 x 50 x 20 feet, was constructed next to the 20,000 gallon diesel tank installation. The west dry storage building, with dimensions of 100 x 30 x 20 feet, will be constructed in the Batch -Weigh Loadout area. Both structures are of metal frame construction with steel siding and a dirt floor covered with 1 -foot of roadbase material. A temporary contractor maintenance shed was also erected near the east storage building. This shed is a portable framework and canopy which sets on several 4 x 8 foot, 8 -inch thick, modular concrete slabs. In addition to the covered storage buildings, TCC may periodically utilize skid- mounted storage containers or modular shipping containers for temporary storage of materials and supplies on -site. These will generally be placed within existing facilities areas, and will not involve any new surface disturbance. It is anticipated that a maximum of twelve temporary storage containers would be on the site at any given time. Given that contractors are frequently used for completion of special project work on -site, in addition to TCC's temporary storage units, there may be temporary contractor trailers and storage units located in project work areas. Since these facilities are generally portable and are owned or leased by the contractors, they are not considered in TCC's reclamation cost estimates. The locations of any long -term structures (ie: covered storage buildings) are shown on Map 24. All storage and contractor structures and portable units will be removed when no longer needed. Storage and Training Area Transfer The Storage and Training Area (ie: `Trudy's Corner') is located in both Section 31, Township 5 North, Range 86 West, and Section 7, Township 4 North, Range 86 West, and consists of 1.5 acres of disturbed area, which was previously permitted under C 81 -071 (CYCC). This area was transferred to C -82 -056 (TCC) for use as a storage facility and outside training area. Drainage control for this area is addressed by a Small Area Exemption, as discussed in Section 2.05.3(4). Reclamation of this area will occur when the area is no longer required for storage of materials and equipment. Approximately 1,210 CY of topsoil from Stockpiles 3 and 6 will be spread to a 6 inch depth over the area, followed by revegetation using a pastureland seed -mix (see Table 53). Satellite Warehouse /Storage Area (MR 02 -179) A Twentymile ranch warehouse /storage building and associated outside storage /parking area will be utilized as a satellite warehouse /storage site by TCC. The site is located at the intersection of Routt County Roads 33 and 179, as shown on Map 24. When the building is no longer needed by TCC, the material stored there will be removed, and the building will revert back to the status of a ranch warehouse /storage facility.
