The haul road has been designed to control runoff, erosion, and resultant siltation <br />through proper road design, grading practices, installation of ditches and culverts, road <br />surfacing, and stabilization of affected surface areas. <br />Design of the haul road including road location, alignment, dimensions, base and <br />surfacing requirements, and drainage structures, reflects consideration of traffic and <br />load requirements as well as environmental and operation factors. The access road <br />was specifically designed for the 30 ton rear dump truck utilized to haul coal refuse. <br />Design for this unit, which will be the largest, heaviest unit utilizing the road, <br />established the following design criteria: <br />o Maximum Design Speed - 35 MPH <br />o Design Width - 30 feet <br />o Maximum Sustained Grade - 10% <br />When mining and related operations are completed and the refuse pile is reclaimed, the <br />haul road will be reclaimed. <br />Location <br />As shown on the Haul and Light Use Roads Map, (Map 19), a portion of the haul road <br />is located on a stable slope, with the remainder of the road following a ridgeline to <br />ensure road stability. The haul road is situated well above the adjacent Magpie Creek <br />drainage channel and does not cross any other drainages. Drainage from the haul road <br />is collected by a roadside ditch and routed to either Sedimentation Pond No. 5 or Pond <br />No. 4. <br />ROADS CONVERTED: <br />Minor Revision No.55 (MR -55, August 2007) converted Haul Roads to Access <br />Roads.
