SA.^ITA FE LOADOUTS <br />2.05.6 t3) Protection of the Hydrologic Balance <br />f:ontaminat:ion of Surface Waters Downstream <br />------------------------------------------ <br />The mine will have. no discharge for all storms less than the 10 <br />year - ~4 hour event. due to the e:;cavated sumps on each lease. <br />Herms aro;_;nd the lease area provide a safety factor in this <br />design, sa that the storm that would produce discharge from the <br />site wo;_ild be actually greater than the 1~; year - ~4 hour event. <br />For any storm great enough to produce a discharge from the site, <br />the effects would be minimal because of the small size of the <br />operation. <br />Possible Contamination of Ground Water due to Leaching of To>ric <br />--------------------------------------------------------------- <br />• Materials <br />Information on borings near the lease area show that the surface <br />is comprised of a silty, clay material underlain by weathered <br />shale and hard shale, which is not conducive to water <br />percolation. Visual observation of the lease areas shows that <br />the surface material has been highly compacted from heavy <br />equipment and railroad use, and that rain water usually builds up <br />in shallow ponds and evaporates. <br />The impact is also minimized by the fact that the combined lease <br />area is only 3.32 acres and that it has traditionally been used <br />as a rail. car loading site. <br />• <br />621 <br />
