Exploratory holes will be drilled within the permit boundary. Run -off from the related drill pads <br />may not go through a treatment facility such as a sediment pond. Run -off from the pads that <br />does not report to a sediment pond will be filtered through a sediment fence. Design of sediment <br />fences for drill pad configurations are presented in Exhibit 19(20) pages 1 -17. The typical <br />sediment fence configuration and berms are shown on Map 25. <br />Silt fences will be used to treat run -off from exploration holes drilled along the rail corridor <br />similar to what is shown on Map 25. The rail corridor is considered an industrial area. Once the <br />rail corridor drill site is re- graded, no ongoing sedimentation control is required. <br />MR -107 2.05 -1Oc Revised 01/25/12 <br />
