RULE 2 - PERMITS <br />Road layouts are shown on Map 2.05.3 M3, Road Plan View and Profiles, Map 2.05.3 M1A, Mine <br />• Facilities Area (South End) and Map 2.05.3 M1B, Mine Facilities Area (North End). Coal haulage <br />will occur on Road A/B/B -1, from the permit boundary at Routt County Road 27A to the coal <br />stockpile area, a distance of approximately 1.5 miles. The road will be a minimum of 50 feet wide <br />and constructed with a compacted road base and gravel surfacing. Road A/B/B -1 will provide for <br />two -way haulage of both full and empty tractor - trailer haul - trucks moving coal from the coal <br />stockpile to the customers receiving facility. <br />Although the posted speed limit for haul roads will be 25 mph, road horizontal alignment is based <br />on a 40 mph design speed, for safety reasons. Horizontal and vertical alignment have been <br />carefully coordinated so that no horizontal curve begins or ends at the crest or sag of a vertical <br />curve, and in such a manner as to comply with regulatory cross -slope and grade requirements, <br />control erosion, simplify drainage design, and maximize safety and environmental protection. <br />Centerline profiles of the haul roads are presented on Map 2.05.3 M3. A schematic of the typical <br />haul road cross section is presented in Figure 2.05.3 -F1, Typical Haulroad Cross - Section. <br />All haulroads will be constructed in accordance with Rule 4.05.1. Typical construction practices for <br />haulroads will involve implementing temporary drainage and sediment control measures, clearing <br />and grubbing vegetation (limited to the width needed for the roadway and drainage control), and <br />recovery and stockpiling of available soil materials. All soil material recovered from roads and <br />other areas will be placed in the topsoil stockpile located adjacent. to PECOCO Pond (see Map <br />2.05.3 M1A). Potentially acid- and/or toxic - forming or frozen materials will not be used for either <br />road fill or as road surfacing materials. Road fill materials will be borrowed from the overburden <br />excavated from the portal area. <br />• Road base and surfacing designs for the haul roads are based on site soil properties and the methods <br />g P P <br />outlined in the U.S. Department of the Interior, Bureau of Mines, Information Circular 8758, Design <br />of Surface Mine Haulage Roads - A Manual (Kaufman and Ault, 1977). <br />PSCM Permit App. 2.05 -20 Revision 12/17/09 <br />
