Runoff fI~ this area drains south east <br />under the railway tracks with the rail ballast apparently acting as a <br />french drain. To prevent runoff frtan this area fr+~n degrading downstream <br />waters EFCI will construct a sediment fence to capture aryl filter all <br />runoff. Zhe fence is designed to safely pass the runoff frran a 10-year, <br />24-hour event. <br />Given that the subject area is small, runoff and ~„~.,t will be <br />effectively wntrolled by the designed ScxL~*+t fence, and there is no <br />discharge in this area frcan wriergrotmd workings, EF'CT respectfully <br />requests approval of a Small Area F7remption for the sediment trap. F.FCI <br />will ocm¢nit to ongoing maintenance of the southwest aar9imant fence during <br />the period of active operations, including inspection and repair of any <br />significant damage drld perlod7.C S ~~*+t removal. <br />WFS'P LOADC(FP AREA -RAILWAY CUNPATI~lP BFId~I <br />Zhe existing railway containment berm, located on the south side of the <br />railroad tracks in the West Loadout area, effectively diverts disturbed <br />C \...860\TR16 .
