. The discussion presented above provides sufficient evidence that background
alluvial chemistry upgradient o£ the Loadout facility is of "limited use and
quality." In addition, the upgradient and downgradient Dry Creek alluvial
groundwater chemistry is comparable in water type and dissolved loads and,
that Loadout operations have not impacted alluvial water quality downgradient
of the Loadout facility area. Finally, the coal stockpile leachate will have
no impact on existing water use potential o£ Dry Creek or the Dry Creek
alluvial system. Consequently, there is no need for HGTI to install an
additional upgradient alluvial monitor well.
