Sertion - 2.05.3 Hubbazd Creek Canyon Road -Portions of the Hubbazd Creek Canyon road, which provides • public access, were straightened, graded, and gravel-surfaced by U.S. Steel to the configuration shown on the Hubbazd Creek reclamation plan drawings Included in Exhibit 2.05-E5, Reclamation Details) to improve access to the Upper and Lower Hubbazd Creek ventilation sites. Portions of the existing inactive and pazdally redaimed surface facilities aze within 100-feet of the Hubbazd Creek Canyon road. Relocation of portions of the existing road in the vicinity of these facilities was completed to minimize mining-related impacts on the road and to avoid interference with public use of the road. The road, which is currently utilized for operation and maintenance at the Hubbard Creek Fansite, as well as public access, periodic inspection of the reclaimed azeas, monitoring, and landowner/grazing leasee access is owned and maintained by the County and U.S. Forest Service (upper portion of road beyond Forest Boundary). The Lower Hubbazd Creek facilities have been removed and associated disturbance azeas reclaimed. The existing Upper Hubbazd Creek facilities are currently inactive, although the potential exists that they may be utilized in conjunction with future mining activities. Old State Highway 133 - Old State Highway 133, which connects to the new highway approximately 3 miles east of the mine, runs along the north side of the North Fork of the Gunnison River, des in with the Sanborn Creek Mine access road, and provides both alternate access to the mine site and access to the Substation No. 3 and C-Gulch ventilation site. This road was constructed prior to 1976 and is owned by the State of Colorado. OMI maintains the road as a light-use road for mine access. Other Access and Light-Use Roads -Various plant roads in the Elk Creek coal handling, support, and ancillary facilities; East Yard: and Sanborn Creek Mine azeas were constructed prior to 1976 and continue to be utilized as access roads in support of ongoing mining operations. These roads, which total approximately 1.0 miles in length, are relatively flat (< 5 percent grade), with road widths varying from IS to 20 feet. Drainage control for these roads is provided by the drainage and sediment • control systems for the corresponding facilities areas. Since these roads aze within the disturbed azea in accordance with Rule 4.05.2(4), construction certification is not required and the design and construction standazds specified in Rules 4.03.2(3) and 4.03.3(3) are not applicable. Other roads, which aze outside of the disturbed azea have been designed and constructed in compliance with applicable provisions of Rule 4.03.3. Road locations are shown on the Mine Facilities Map, (Map 2.05-M1). The following summarizes and describes the miscellaneous light-use roads which exist within the Permit Area: A. Sedimentation Pond CRoad -Alight-use road extends from the employee pazking azea neaz the mine entrance to Sedimentation Pond C to provide access for pond inspection, maintenance, and monitoring. This road is approximately 1,800-feet long. B. Sanborn Creek Mine Overland Conveyor Road -Alight-use road beginning at the conveyor crossing of the Sanborn Creek Mine haul road and paralleling the elevated portion of the conveyor provides access for conveyor inspection and maintenance. Tlus road is approximately 400 feet long. C. Substation No. 3 and C-Gulch Ventilation Site Road - A short light-use road connects the Substation No. 3 and C-Gulch Ventilation site with old State Highway • TR-49 2.05-30 Revised January 2005
