rock fill consisted of durable (non - erodible) material. The fill was placed as <br />shown in Exhibits 7B and 22. The size gradation was in accordance with the <br />Army Corps of Engineers' specifications, since a permit was necessary for <br />placement of the material. <br />ROADSIDE NORTH PORTALS (RSN) <br />Drainage above the RSN operations was collected in diversion ditches and <br />transferred around the operations area to the east and the west. Drainage within <br />the reclaimed area was directed to one of two locations: Pond 13, or the <br />sediment fence. A berm transected the reclaimed area in a northeasterly <br />direction. Run -off below the berm was directed to the sediment fence and run- <br />off above the berm was directed to Pond 13. Runoff from the topsoil piles 1 and <br />2 was directed to Pond 13. The sediment fence was removed in 2009 with the <br />approval of TR -58 and Pond 13 will be removed upon approval of PR -5. <br />See Tab 14 for a description of the ditches to be constructed and made part of <br />the permanent East and West Diversion Ditches. These ditches are designed to <br />accommodate storm runoff from the drainage originating on the slopes above the <br />reclaimed area. <br />Areas around the RSN operations area that were covered by alternate sediment <br />control include the powder and cap magazines. Further descriptions of these <br />areas are given in Table 13 -5 with backup information in Appendix 13 -3. <br />PR -5 13 -10 (Rev. 02/12) <br />
