Box 229 eregE warner <br />Eeecmrve Dueclor <br />Boulder, CO 80306 Michael B. Long <br />Division Director <br />RE: Bourg Mine, Permit C-81-021 <br />Annual Reclamation Report and Annual Hydrology Report <br />The DMG has received and reviewed the 1998 Annual Reclamation & Hydrologic <br />Monitoring Report submitted by the Flatiron Companies. We have reviewed the <br />information with the understanding that a final bond release application will be submitted <br />in the near future. With this in mind we have the following comments. <br />The vegetation monitoring data indicates success. None of the "raw" vegetation data <br />was submitted in the Vegetation Monitoring Report. For the final bond release <br />application we will be requesting the vegetation data for each cover and shrub density <br />[ransect. and the individual plot data for production. <br />2. A revised species diversity standard will be submitted by Flatirons. The stipulated <br />standard is not reflective of premining conditions, the reference areas or the reclaimed <br />areas with respect to the tninimum and maximum relative cover values. <br />3. The Annual Hydrology Report does not address a spring and seep survey. The DMG <br />has not observed any on-site, but [he presence or absence of springs and seeps should <br />be addressed in the bond release application. <br />4. The Annual Hydrology Report was reviewed by the Division. In general, there has <br />been a consistent pattern in the groundwater chemistry between [he wells and they <br />demonstrate anticipated trends. <br />If you have any questions regarding this letter, please feel free to call me. <br />Sincerely, <br />andra L. Brown <br />Environmental Protection Specialist <br />
