<br />The south ditch will Handle 4ti.y cis (maxi;num design flox). The nortn <br />ditch will handle 5j.2 cfs (maximum design floxj. Table 1, Appendix 3, <br />cocctains design calculations for these ditches. Ditches xill oe cut to <br />oedrock or rip-rapped on steep portions suoject to erosion. liFC will <br />provide the Division with as built draxings and specifications after <br />construction. <br />Pond UU4A xill not receive any additional drainage as a result of pile <br />construction. As such, Pond UU4A will not have to be modified. <br />The stability analyses is provided in r;xhibit S. The staoility <br />analyses indicate factors of safaty above the minimum criteria set forth by <br />tcie Division. <br />CUY~H PL4T~;RIAL FOR WASTE PILH <br />WFC proposes to reclaim the pila with 4 ft of cover. This will include <br />• topsoil and subsoil obtained from Areas 1 through 4 as suoxn on r'igure 1. <br />WFC plans to cut up to a.d ft in Areas 1 and 4. <br />Cover suitability xill be determined by sampling to a depth of d ft in <br />Areas 1 and 4. Three samples will be taken to a depth of d ft. Approximate <br />sample locations are shown on Figure 1. Composite samples will oe taken at <br />2 ft intervals. The intervals will be U-2 ft, 2-4 ft, 4-o Yt and o-d ft. <br />Samples will be analyzed for pH, ~;c, SAlt, texture and percent cock fragments <br />(percent rocK fragments will be estimated in the fieldj. <br />Area 4 will not be sampled until the present pile is moved. Area 1 <br />will be sampled the weeK of July 1}, 19d7. wFC expects the turn-around ti!¢e <br />for lab results will be 4-6 weeks. 'dr'C requests the pile expansion begin <br />prior to receiving final lab results. <br />-5- <br />
