r1 <br />U <br />1. Possible degradation of ground water cuality resul*_ing <br />from leaching of the coal storage pile or leakage from <br />sedimentation ponds. Base3 on the water quality <br />characteristics of these t•ao sources, elevated levels <br />of sulfate would be the most li:cely change in ground <br />water quality. It is unlikely that sulfates would occur <br />at concentrations that would affect plant production, <br />in the area of the UTL Site. <br />2. Possible increases in alluvial water levels from leaky <br />sedimentation ponds planned for the N E edge of the rail <br />loop. <br />• The quality and quantity of water available for flood irriga- <br />tion to the AVr^ via the Highline Canal will not be affected by <br />operation of the UTL. The canal itself has not been affected by <br />the UTL operation ( nor will it be in the future) .
