SAi4TA FE LOADOUTS <br />2.05.3 (4) Ponds, Impoundments and Diversions <br />• Both loadout sites are very small, e;:tremely flat sites that <br /> produce virtually no runoff at. the present time. Lease sate #1 <br /> is located between two railroad trac4;s which are at higher <br />elevations than the lease area itself. <br />The overall plan for sediment control a't both sites is to provide <br />a sump to contain the runoff from the 10 year - 24 hour storm <br />and the sediment storage volume for a ~ year period. Material <br />ea;cavated for the sump will be used to provide berms where <br />necessary along the lease area to ins~.~re that no runoff will <br />leave the site. <br />E:;isting <br />Lease Name Area Description Acres Curve Number Land Use <br /># 1 Railroad yard 1.'0 87 Industrial <br /># 2 Railroad yard 2.02 87 Industrial <br />Sump designs far both leases: <br />----------------------------- <br />The 10 year - 24 hour precipitation at this site is _+.~~0 inches. <br />The 10 year - 24 hour runoff is 1.74 inches. <br />Fond volume required to contain the 10 year - 24 hour storm <br />runoff is: <br /> <br />615 <br />
