train, incoming coal haulage will be diverted to Haulroad A, continuing on Haulroad B -1, the Haulroad B -1 Extension, and the Refuse Haulroad to the ROM Pile, and returning the same way. Since all existing haulroads are designed and constructed to handle the loads and speeds associated with coal haulage traffic, the only modifications necessary for the Sage Creek coal haul will be minor widening and straightening of some haulroad segments to accommodate two -way traffic, increase capacity, and improve safety (ie: curves and sight distances), reconstruction of a short segment of the Refuse Haulroad and Haulroad B -1 Extension to haulroad standards, replacement or relocation of one or more conveyor bents where Haulroad B -1 parallels the Overland Conveyor, placement of additional signage, and associated minor drainage modifications. All required modifications will occur within existing disturbance areas, and road segments which are widened or realigned will be constructed and inspected consistent with the existing road designs. Associated drainage modifications will involve shortening or extending ditches and culverts, as necessary to match the road modifications. III. Access Roads Fish Creek Borehole Dewaterin¢ Site Providing access to the Fish Creek Borehole Site will involve upgrading 6500 feet of an existing road and construction of an additional 2500 feet of road. The location of the area and access road is shown on Map 26, Fish Creek Borehole Area and Access Road. The existing road was designed so that construction, maintenance, and postmining condition of the road will control erosion, siltation, and pollution of water and prevent damage to public and private property. The overall grade does not exceed 10 percent nor do pitch grades exceed 15 percent for any consecutive 1,000 feet. To accommodate a low volume of larger delivery trucks, TCC made minor alignment changes to the access road. These minor changes improve the alignment of the road through several short curved sections and are located within the 200 -foot road corridor, as indicated along the final 2,500 feet of the road. Additional gravel was also added to the existing road consistent with the increased traffic requirements. The access road will not cause material damage to fish, wildlife, or related environmental values and will not contribute suspended solids to stream flow in excess of the State and Federal limitations. The access road has been designed to meet the requirements of Rule 4.03.2 with consideration of the specific use, volume of traffic, and weight and speed of vehicles as shown in Exhibit 25p. The first 6,300 feet of road from County Road #27 will remain as permanent road. Colorado Mined Land Reclamation Division (CMLRD) granted approval in February of 1988 for the retention of the road as a permanent access (Technical Revision 87 -12; Permit C- 81 -071). Reclamation of that particular section will be performed as discussed in Technical Revision 87 -12. The remaining 2,500 feet leading to the settling pond will be reclaimed once mining activities cease, unless approved otherwise by the Division. Shoo/1Maintenance Area/Warehouse Access Road TCC upgraded the access road into the Preventative Maintenance Bay as per the recommendation presented in the report dated October 9, 1995, prepared by Northwest Colorado Consultants, Inc. The access road certification is contained in TCC's road certification file. This particular certification is dated May 30, 1996. Truck Delivery Access Road In order for supplies and materials to reach the storage building, an access road has been designated. This road will be located on the east side of the coal stockpile. Drainage from the road will be controlled by the existing sedimentation control system. Flow will be conveyed by Ditch D -2 and Ditch D -5. The access road will be constructed to meet the requirements of Rule 4.03.2. TR12 -80 2.05 -73 11/07/12
