Walther <br />Minrec, Ino. Executive Direcl0r <br />2768 Compass Drive Suite 101 <br />, Michael B. Long <br />Dwision Director <br />Grand Junction CO 81506 <br />Deaz Mr. Stover: <br />The Division has completed review of the 2000 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 are correct or the hydrologic <br />impact is less than predicted. <br />To wit, there was no evidence from the data that there was increased erosion from the disturbed <br />area, compared 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 Hubbard Creek caused by water transit <br />through the backfilled bench area was not demonstrated by the data from the Creek itself. <br />"Snapshots"' of Hubbard Creek conductivity show ambiguous results, but certainly no <br />systematic increase in the content of total dissolved solids from upstream to downstream past [he <br />disturbed area. <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 />~ ~~~~~~~ <br />Jim Burnell <br />Environmental Protection Specialist <br />cc: Sandv Brown <br />
