Enclosed is an application for a technical <br />revision which will incorporate the revised sediment pond design, <br />Map 11-3, into the permit. The revised sediment pond design is <br />consistent with the existing design calculations contained in <br />Exhibit 11. <br />The redesign of the pond requires: <br />1. The embankment to be raised an average of 6-inches; <br />2. The spillway to be reconfigured; and <br />3. The pond to be expanded to the north in order to provide the <br />required water capacity. <br />The material excavated to expand the pond will be pit run material <br />that will be used to fill in the slide area. <br />Please call if you have any questions. <br />Sincerely, <br />Jim Stover, P.E. <br />Consulting Engineer <br />Enclosures <br />cc: W.
