The following findings and specific approvals are required by Rule 4: <br />L Roads - Rule 4.03 <br />Information on roads is presented in Section 2.05.3, in Tab -13 of the permit application. <br />During operations there were six haul roads, five access roads and five light -use roads within the permit <br />area that demonstrate compliance with applicable standards of Rule 4.03. All the roads met the design <br />criteria for grade and surfacing. All were found to be in compliance. Two pipe arches which convey <br />runoff flow in Coal creek beneath Haul Road 4 near the Roadside North Portal have an end area of <br />greater than 35 square feet; therefore, to be in compliance with Rule 4.03. 1(4)(e)(1), they must pass the <br />20 -year, 24 -hour peak flow. The permittee installed inlet transitions in order to pass the event. <br />New Access Road IA was approved with PR -3 in 2007 and was constructed on Snowcap Coal Company <br />property to implement the alternative "Industrial or Commercial' postmining land use and to provide <br />access to the permanent facilities at the South Portal area. The segment of Access Road 1 between the <br />lower parking area and the mine bench was reclaimed in 2008. Access Road IA and a short upper <br />segment of Access Road 1 (approximately 100 feet in length) were approved as permanent with PR -3 <br />and will be retained for the alternative postmining land use. The segment of Access Road 1 to be <br />retained will provide access to proposed equipment storage areas located on the flat top of the RSRDA <br />waste disposal site. <br />Three dip- sections were installed along coal creek during construction of Haul Roads 2, 3 and 4. The <br />two upper dip- sections have six 36 -inch CMP culverts laid side by side and incased in concrete. In the <br />concrete, they have an end area greater than 35 square feet, therefore, they must pass the 20 -year, <br />24 -hour peak flow to be in compliance with Rule 4.03. 1(4)(e)(1). The lower dip section is only required <br />to pass the 10 -year, 24 -hour peak flow to be in compliance with Rule 4.03.1(4)(e)(1). <br />Designs reveal that the dip- sections will not pass the design peak flows without overtopping. In 1982, <br />the permittee submitted justification that the dip- sections would be as environmentally sound as designs <br />which would comply with Rule 4.031. 1(4)(e)(1). Since the dip - sections are constructed of reinforced <br />concrete, they will not erode if overtopped. In addition, the upstream and downstream sections of the <br />stream are protected by riprap so they will not be undermined. The overtopping of the dip- sections will <br />likely be a gradual event. The water will flow over the top of the smooth concrete surface with very little <br />turbulence being induced by the dip- section. According to calculations done by the permittee, the <br />dip- sections would be overtopped for a total of 3.4 hours during a 20 -year, 24 -hour precipitation event. <br />The installations are therefore acceptable to the Division. <br />In conjunction with reclamation activities within each of the surface facilities areas, a number of roads <br />will be removed and restored to approximate original condition. All culverts will be removed, natural <br />drainage patterns across each road will be reestablished, and all disturbed areas will be revegetated. <br />Certain roads will be retained for postmining use, in accordance with landowner requests for use <br />following completion of mining and reclamation. Road retention narrative and documentation is <br />provided on Page 14 -14 and in Appendix 14 -5. New Access Road IA, to be constructed in conjunction <br />with South Portals area reclamation, will be retained in its entirety for the alternative postmining land <br />use, as will a short upper segment of existing Access Road 1. Landowner request for retention of these <br />road segments is provided on Appendix pages A14 -5 -29 and A14- 29 -30. In addition to the haul road <br />19 <br />
