• 8) Haul Roads and Other Facilities <br />General Requirements. WFC will construct, maintain and reclaim haul roads in the <br />amendment area to the same specifications as listed in Section 2.05.3 of the existing permit <br />unless specified differently in this section. The roads will be designed to minimize erosion and <br />siltation, air and water pollution and damage to public and private property. To the extent <br />possible, using the best technology currently available, haul roads will not cause damage to fish, <br />wildlife, or related environmental values and will not cause additional contributions of suspended <br />solids to stream flow or to runoff outside the permit area. <br />Location. The amendment area will have a haul road on both the north and south perimeter of <br />the pit area. These roads will be referred to as the north and south haul roads, respectively. The <br />north haul road is approximately 5600 feet long and the south haul road is approximately 3200 <br />feet long. The plan and profile views of these roads are shown on Map 2.05.3-14. <br />Haul roads at the mine site will be designed with appropriate ditches, grades and culverts to <br />control erosion and runoff. All haul roads will be constructed basically "on-grade", although <br />certain parts of the north haul road will require some minor cutting and filling to maintain <br />acceptable road grades. Topsoil will be removed and stockpiled in accordance with WFC's topsoil <br />• salvage plan. The location will be partially limited by the grades of the existing or postmining <br />areas. Stream fords will not be used during construction of roads unless approval is first obtained <br />from the regulatory authority. <br />Design and Construction. The design of the haul roads incorporate the demand for mobility <br />and travel efficiency, based on the geometric criteria appropriate for the anticipated volume of <br />traffic, weight and speed of the vehicles to be utilized. The design and construction or <br />reconstruction of haul roads not within the estimated disturbed area will be certified by a <br />registered professional engineer, if required by the CDMG for good cause shown. <br />Should haul roads not within the estimated mining disturbance areas be necessary, they will be <br />designed and constructed or reconstructed in compliance with the following standards in order to <br />control erosion and disturbance of the hydrologic balance. <br />The vertical alignment of the haul roads will not exceed 10 percent on the overall grade. <br />Maximum pitch grade will not exceed 15 percent, and there will not be more than 300 feet of pitch <br />grade exceeding 10 percent within any consecutive 1,000 feet. <br /> <br />(Revised 12/00) Attachment 2.05.3(3) -10-99 <br />
