State Reo. federal law. The location of all existing and proposed roads • are shown on Exhibit 7-7 and 12-1. 4.03.1(2) Location. There are approximately 10.6 miles of existing haul roads at the Seneca Mine and over the next five years there are no new haulage roads planne3 outside of the estimated disturbance area, (see Exhibit 12-1). The haul roads at the mine site are designed with appropriate ditches, grades, and culverts to control erasion and ivnoff. All haul roads will be constructed basically "on~rade" and the location will be partially limited by the grades of the existing or postmining areas. Stream fords will not be used during construction of roads unless approval is first obtained from the Division. All truck traffic will be routed to enter the pits at the upper elevation end and leave the pits at the lower elevation end. The haul roads in the Wolf Creek area pit will be built prior to mining and reclaimed as the roads are mined or when • the roads are no longer needed. The haul roads in the wadge pit will be extended through the spoil and road wnstruction will progress with the mining activity. Reclamation of these roads will occur at the end of the life of the mine. 2.05.3(1)(c)Design aril Construction. The design of the haul roads 4.03.1(3) incorporates the demand for mobility and travel efficiency, based on the geometric criteria appropriate for the anticipated volume of traffic, weight, and speed of the vehicles to be utilized. The design and construction or reconstruction of haul roads not within the estimated disturbed area will be certified by a registered professional engineer, if r~sired by the CNIII?B for good cause shown. In these disc.~ussions recanting roads, reference to estimated disturbed areas or disturbance areas refers to areas estimated to be disturbed by the actual mining excavation and the activities associated with reclaiming the mining excavation • disturbances. 12-24 Revised 12/10/92
