RULE 3 PERFORMANCE BOND REQUIREMENTS Rule 4 Performance Standards 4-5 Revision Date: 4/6/23 Revision No.: TR-159 4.03.2 Access Roads The Taylor Creek Access Road provides access to the East Taylor Ponds from Haul Road A. The Taylor Creek Access Road is a pre-mining two-track or ranch road that has been upgraded for a more stable driving surface than the pre-mining road provided. The Taylor Creek Access Road will not meet all the requirements for an access road under Rule 4.03.2 as the existing road will be graveled, and a small berm is constructed to meet MSHA requirements. Please see Map 25C for design details for the Taylor Creek Access Road. The Taylor Creek Access Road has been requested by the surface landowner to remain as a permanent structure. Please see Volume 2B, Exhibit 1B for request of the Taylor Creek Access Road to remain post mine. Information related to the Sturgeon Access Road is found in Volume 12, Section 4.03.2. Several access roads will be constructed in the East Pit to allow access to manage post-mine channels, stock ponds, and to construct sediment ponds. Please refer to Volume 2E, Appendix Exh. 7-14R for additional details on the East Pit Access Roads. 4.03.3 Light-Use Roads The location of light-use roads will be determined on the basis of the progress of the mining operation and specific design and environmental considerations. Typical light-use roads will be "access" roads of recent construction in the pit areas for blasting and maintenance, exploration roads, and reclamation access roads. Light-use roads, whether in the pit or other areas, will be constructed using the best technology currently available, to the extent possible, to avoid damage to fish, wildlife, and related environmental values and to prevent additional contribution of suspended solids to runoff outside the permit area. Roads in the pit areas will be constructed on an already disturbed material. Reclamation access roads and exploration roads will be restored immediately after they are no longer needed. Information contained in Section 2.05.6 reveals that no fish and wildlife damage will result from mining operations, including the construction or operation of light-use roads. The light-use roads will be used by pick-ups, light-duty service trucks, track-mounted overburden drilling rigs and tractors. The location of the light-use roads will be determined largely by the immediate need of the mining operations. They will not be located in the channel of any major drainage unless specifically approved by the Division. Light-use road construction will generally require no topsoil removal. Roads in pit areas will already have been pre-stripped of topsoil for mining and the construction of exploration roads will only require removal of any large vegetation. Light-use road maintenance will include maintaining natural drainages across the roadway and periodic dozing to remove loose material which might contribute to sedimentation or road instability.
