RULE 2 - PERMITS <br />and provisions for disposal of unsuitable materials, consistent with applicable provisions of Rule <br />• 4.03.3, 4.05.2(4), 4.05.18, 4.06.2, 4.06.3, 4.06.4(2), 4.09.1, 4.15 and 4.17. <br />Temporary runoff and sediment control measures are implemented prior to road construction to <br />control runoff, erosion, and sediment transport from the associated disturbed areas. Such measures <br />may include, but are not limited to, the use of temporary berms and placement of silt fence and/or <br />straw wattles or bales to intercept and control drainage. <br />Road construction methods are similar for all classes of roads, with construction generally involving <br />initial clearing of vegetation and recovery of available soil materials, cut -fill excavation and <br />placement, installation of drainage structures, grading, and placement of surfacing materials. For <br />access and haulroads, fill and embankment construction involves placement and compaction of fill <br />materials in horizontal lifts approximately 12 inches deep over the width of fill or embankment. Fill <br />material is not placed in its final position, but dumped and then bladed to facilitate moisture <br />conditioning and proper compaction. Compaction is carried to the edge of the fills so that final <br />embankment slopes are firm and stable. Where fills are placed against existing slopes, the slopes <br />are benched and scarified and the loosened material blended with the fill during placement and <br />compaction. <br />When a roadside ditch is required, ditches are cut to the design configuration and grade following <br />completion of road construction and lining material (if required) is placed to limit erosion and <br />control flow velocities. Culvert installation involves excavation to competent material, placement <br />of bedding material, culvert installation, placement and compaction of fill and cover material <br />around and over the culvert, and placement of appropriate headwall and outlet protection where <br />• required. On completion of road construction, associated cut - slopes and embankment out - slopes <br />are seeded with the temporary seed mixture and mulched to stabilize the slopes and minimize <br />erosion potential. <br />Road A/A1, Road B/B 1, Road C, Road E and Road E -1 will be retained as permanent postmine <br />features after the mine operation ceases to be consistent with the Seneca II Mine approved post <br />mining land use, as well as the proposed Peabody Sage Creek Mine postmining land use. The road <br />width will be reduced to 20 feet and drainage reestablished as part of the final road configuration. <br />A sign identifying the name, address, and telephone number of the mine permittee, along with the <br />current permit number and permitting agency and contact information will be posted at the entrance <br />to the permit area on the mine access road, and maintained, consistent with applicable provisions of <br />Rules 4.02.2 and 4.02.4. <br />Haulroads - Haulroads will be used for coal haulage, overburden haulage and mine development <br />waste rock haulage; the haulroads include: <br />• Road A/A -1 <br />• Road A -2 <br />• Road B/B -1 <br />• Road C <br />• 0 Road D <br />PSCM Permit App. 2.05 -19 Revision 12/17/09 <br />
