<br />(2) <br />June 18, 1984. During the⢠construction on this pond the accumulated sediment <br />was removed. The affected emhankment was re-seeder] in October 1984. The sed- <br />iment volume used in the previous certification wa:; taken from information in <br />the permit. The 0.102 a. E. stated in the permit is higher than the 0.084 a.f. <br />found once the sediment was removed. The 0.130 a.E. design sediment requirement <br />was a very conservative figure calculate using OSM's Initial Program rules. <br />Rather than enlarge the pond, the pond will be considered to be 357, Filled with <br />sediment, leaving 257, capacity available before clean-out is necessary. The <br />attached drawing shows the levels oC Che discharge structures and the volumes <br />of storage. <br />I certify that these ponds, ~t3 and fk4, have been re-established under my <br />direct supervision and that to the best of my knowledge and belief these ponds <br />are structurally sound and have the storage volumes shown on the attached drawing. <br />.w..yy` <br />l'1 / , r . <br />Larry pl: R chke, PE 19691 ti <br />~~ <br />Alt , <br />A.~l ~ :~~~ !a ~ r s ~ <br />
