• 2.0 RUNOFF AND SEDIMENT CONTROL PLAN <br />Upland drainage from the area above the fan site as shown in SGF-O1 will <br />be diverted away from the fan site by a ditch as shown in SGF-02. The <br />upland runoff diversion ditch will discharge into a natural drainage which <br />empties into Sylvester Creek. An 18" CMP will divert the flow under the <br />light use road as shown in SGF-02. See Appendix A for ditch design <br />details. <br />The fan, as discussed in Section 4.0 of this application, will be <br />constructed on a concrete pad surrounded by a gravelled parking pad. <br />Total disturbance for this project, exempting the re-routed light use <br />road, will be approximately 0.6 acres. Due to the small amount of <br />• disturbance, a small acreage exemption from construction of a <br />sedimentation pond is requested for this project. Erosion from the pad <br />site will be minimal due to the relatively level grade of the pad and the <br />fact that the pad will be gravelled. Filter fabric will underlay the <br />gravel. The gravel and filter fabric wilt not only serve to minimize <br />erosion but will also serve to retain most if not all of the sediment, <br />should any be generated by runoff. Mine water will not be discharged at <br />this site, thus no co-mingling of mine water with precipitation-generated <br />runoff will take place. <br />If a sediment pond was to be constructed for the fan site, the disturbance <br />necessary for pond construction including the pond, the outlet works from <br />• the pond to Sylvester Creek as well as the access road to the pond would <br />be more than that necessary for the fan pad itself. <br />
