Mr. Jeff Greg <br />June 9, 2003 <br />Page 2 <br />Erosion Control Measures <br />~~ <br />CIVIL RES`~URCES,LLC <br />Erosion control is achieved by redirecting clear water generated from upstream areas, in turn minimizing silt <br />introduced into the downstream wetlands and waterways. Additional erosion control measures, such as silt <br />fencing, may be desirable to provide additional control especially to the north of Pods 1-4 and to the south of <br />Pod 5. Figure 2 and 3 illustrates erosion mitigation measures. <br />Schedule <br />The Bernhardt Resource Pit will be mined in phases as seen in Appendix B. Mining will begin to the west <br />and proceed to the southeast, finishing in the northeast comer at Pod 5. Therefore the drainage measures <br />will be implemented as mining progresses. <br />Summary <br />The measures presented above and on Figures 2 and 3 are standard measures and more effort to control <br />stormwater might have to be implemented as a result of changes in the mining plan or areas of concern as <br />mining progress. Civil Resources believes this plan will control stormwater on the site and prevent erosion <br />and sedimentation of wetlands and waterways downstream. <br />Sincerely, <br />Civil Resources, LLC <br />ndrew R riguez, E.I.T. <br />Water Resources Engineer <br />ARR:arr <br />attachments <br />cc: Larry Ketcham, Town of Milliken (w/attachments) <br />Tetra Tech RMC (w/attachments) <br />Z:lprojecrSlHall-Irxin~Bemhardtlswmp.doc <br />
