disturbed, there is not any topsoil to be salvaged. A <br />front end loader and/or cat will be used to construct <br />the embankment. The embankment will be compacted by <br />routing of the equipment over the embankment as it is <br />constructed. <br />A two inch gated principle spillway will be instal- <br />led. The gated spillway will have two anti-seep collars <br />installed as shown in Drawing 3, Sediment Pond SP-1. <br />The embankment slopes will have a maximum slope of 2~1. <br />The water discharged from the pond will flow into <br />a ditch which goes into the existing drainage of the <br />area. The emergency spillway and ditch below the prin- <br />ciple and emergency spillways will be riprapped to pro- <br />• vide energy dissapation and control erosion of the spill- <br />way outlets. <br />The sediment control system for the waste disposal <br />area will consist of diversion ditches. DD-5 and DD-6, <br />to divert the drainage upslope of the disposal area a- <br />round the disturbed area. A sediment pond, SP-2, will <br />be constructed at the toe of the fill area. The sedi- <br />ment pond will use the same construction procedures as <br />outlined for Sediment Pond SP-1. An ungated principle <br />spillway will be installed in SP-1. The design calcu- <br />lations are shown in Appendix F. <br />Diversion ditches will be constructed with a dozer <br />angling the ditch into the hillside. There will not be <br />• any topsoil salvaged from the diversion ditch locations. <br /> The diversion ditch designs are included in Appendix F. <br />93 <br />
