Walther <br />Executive Director <br />Minrec, Inc. <br />Ronald W. Cattany <br />2768 Compass Drive, Su1te 101 Atting Division Director <br />Grand Junction CO 81506 <br />Deaz Mr. Stover: <br />The Division has completed review of the 2002 Annual Hydrology Report for the Blue Ribbon <br />Mine. We found that, based on monitoring for the year, 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 area, 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 yeazs. <br />The prediction that there would be increased salt load in Hubbazd Creek caused by water transit <br />through the bacl~lled bench area was not demonstrated by the data from the Creek itself. <br />Analyses of conductivity from Hubbazd Creek show ambiguous results, there is no evidence of <br />an increase in salinity from the mine itself. <br />The impacts of the very dry yeaz are obvious in the data. <br />Thank you for the timely submission of the report. If you have any questions, please feel free to <br />call me. <br />Sincerely, ~ <br />~ ,a <br />,~ <br />Jim Burnell <br />Environmental Protection Specialist <br />cc: Sandy Brown <br />
