Walther <br />Executive Director <br />Ronald W. Cattany <br />Acting Division Director <br />The Division has completed review of the 2001 Annual Hydrology Report for the Blue Ribbon <br />Mine. We found that, based on monitoring for the yeaz, that the predictions contained within <br />the probable hydrologic consequences (PHC) section of the permit aze correct or the hydrologic <br />impact is less than predicted. <br />Specifically, there was no evidence from the data that there was increased erosion from the <br />disturbed azea, compazed to the surrounded undisturbed area. <br />There was no impact from oil and grease since machinery hasn't been present on the site for <br />many years. <br />The prediction that there would be increased salt load in Hubbazd Creek caused by water transit <br />through the backfilled bench azea was not demonstrated by the data from the Creek itself. <br />"Snapshots" of Hubbazd Creek conductivity show ambiguous results, but certainly no <br />systematic increase in the content of total dissolved solids from upstream to downstream past the <br />disturbed azea. <br />Thank you for the timely submission of the report. If you have any questions, please feel free to <br />call me. <br />Sint . l yf``~ -,~'~~2X~C <br />Burnell <br />Environmental Protection Specialist <br />cc: Sandy Brown <br />
