topography of the existing stockpiles is consistent with the approved post- mining topography as <br />shown on Exhibit 20 -2. <br />Dragline Assembly/Disassembly Pad —This area was to be regraded to approximate original <br />contour, as shown in Exhibit 20 -2 of the permit application package, and the drainage tributary <br />to Armand Draw reestablished. <br />Drainage YPM -20 — YPM -20 is an approved post- mining drainage channel. Design of the <br />channel, which was to be field fit, called for a trapezoidal channel with either erosion control <br />matting or rock rip rap lining and 3:1 (if rip rap) or 4:1 (if erosion control matting) side slopes. The <br />approved overall grade of YPM -20 was 12.3 %. <br />Drainage YPM -8 - YPM -8 is an approved post- mining drainage channel. Design of the <br />channel, which was to be field fit, called for a trapezoidal channel with either erosion control <br />matting or rock rip rap lining and 3:1 (if rip rap) or 4:1 (if erosion control matting) side slopes. The <br />overall grade of YPM -8 was approved to be 8.9 %. <br />YPM -8 Watershed — This area was to be graded to approximate original contour, as depicted in <br />approved Exhibit 20 -2, drainages reestablished, and the area was to be topsoiled and reseeded. <br />Light Use Road LU -3A — This road was to be narrowed from a haul road (Haul Road B and <br />Haul Road B Extension) to a permanent light use road averaging 12' wide. Cut and fill areas <br />were to be blended with the surrounding topography. Topsoil was to be redistributed on the <br />regraded surfaces outside of the 12' roadway, and the topsoiled areas reseeded. <br />Light Use Road LU -3B — This road was to be narrowed from a haul road (Haul Road C and D) <br />to a permanent light use road averaging 12' wide. Cut and fill areas were to be blended with the <br />surrounding topography, and water bars were to be installed to control drainage across the road. <br />Topsoil was to be redistributed on the regraded surfaces outside of the 12' roadway, and the <br />topsoiled areas reseeded. <br />Stock Tank ST -1— No reclamation was required for this impoundment, as it has been permitted <br />as a permanent impoundment in its current configuration. <br />Unnamed Roadway Corridor — This road is not depicted on Exhibit 20 -2, nor is it included in <br />the permanent structures /features discussion of Attachment 20 -1. According to the currently <br />approved reclamation plan, this corridor was to be regraded to approximate original contour as <br />shown in Exhibit 20 -2, topsoil replaced, and the area reseeded. If the operator wishes to retain <br />this road on a permanent basis, an application for a revision to the permit must be submitted to <br />and approved by the Division. This area was not considered for bond release because it is within <br />Page 6 of 27 <br />Yoast Mine SL -4 <br />
