(CYCC) as the Preventive Maintenance Bay. Uses of the shop area include construction, maintenance, and storage <br />of materials, equipment, and various supplies. Access to the 2.5-acre shop facility is designated on Map 24, <br />Surface Facilities. <br />The parking area east of the above referenced building is being improved to allow better utilization of the area. The <br />improvements required hauling in approximately 2500 CY of spoil material to fill in the existing parking area and <br />raise it so that runoff drains to both the north and south from this area. Drainage from this area is directed into <br />ditches D-2, G-4, and D-6 (a and b). Design information for these ditches is contained in Exhibit 8. <br />A small building has been constructed on the east side of the portal entry. The 10 X 12 X 8 building will house the <br />portal slope heating system. <br />Satellite Warehouse/Storage Area (MR OZ-1791 <br />A Twentymile ranch warehouse/storage building and associated outside storage/parking area will be utilized as a <br />satellite warehouse/storage sire by Twentymile. The site is located at the intersection or Routt County Roads 27 and <br />33 and is shown on Map 24. When the building is no longer needed by Twentymile the material stored there will be <br />removed and the building revert back to the status of a ranch warehouse/storage. <br />Communication Line <br />A communication line, as shown on Map 24, was installed to tie in the warehouse with the existing network. A <br />segment of the line is buried, while the remainder is hung from existing poles. <br />Waste Water Treatment Facili <br />• Anew wastewater treatment facility was constructed at the Foidel Creek Mine. This facility was designed by <br />Schmueser Gordon Meyer, Inc., an engineering firm located in Glenwood Springs. The facility is an aerated lagoon <br />system, comprised of three treatment ponds and a "polishing" pond. The facility's locations are shown on Map 24, <br />Swface Facilities. TCC has received both a site application and a discharge permit for this facility. The Colorado <br />Department of Public Health renewed the discharge permit number CO-0042161 on March 1,1995. <br />The treatment facility required the installation of a sewer line from the new bathhouse to the ponds and an existing <br />bathhouse, which is located behind the shop/warehouse, to the pond system. As stated above, the treatment facility <br />required the construction of fow ponds. The ponds were lined with clay. The cut and fill balance for the ponds <br />were estimated at 8237 CY of cut and 5297 CY of fill, which resulted in an excess of 2940 CY. This material was <br />stockpiled adjacent to the facility at the location shown on Map 24. Prior to excavation available topsoil, <br />approximately 12 inches, was removed and stockpiled adjacent to the facility at the location shown on Map 24. <br />TCC obtained approval to move slightly downslope of the current distwbance associated with the construction of <br />the wastewater lagoons to borrow underlying clay materials. This material was used in the construction of the <br />compacted liners in the previously approved wastewater lagoons. <br />• <br />MR 02 - 179 2.05-19 08/06/02 <br />
