,~ <br />STATE OF COLORADO <br />Roy Romer, Governor <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />DAVID C. SHELTON, Director <br />March 25, 1987 <br />Craig Springer <br />Bear Coal Company <br />P. O. Box 518 <br />Somerset, Colorado 81434 <br />Re: Review of Bear Coal Annual Hydrologic Report <br />Dear Mr. Springer: <br />The Division had completed its review of Bear Coal Company's Annual Hydrologic <br />Report. Analysis of the data contained in the report indicates that no <br />degradation of surface or ground water resources has occurred as a result of <br />mining at the Bear Mine. The report indicates that Bear discharged from its <br />sediment pond on June 27, 198fi. The effluent discharged at this time was <br />within NPDES permit effluent limits. Review of alluvial ground water field <br />• parameter data indicates that all measurements were within historically ~~~ ~? <br />recorded ranges, wi Y the excep~ n of an electroconductivity__v_alue recorded ~~~~~„~ <br />for Well AA-1 on Jul 24 1986. This value is probably anomalous and perhaps <br />due to an error in data acquisition, Amore thorough study at the site may be <br />required if the elevated electroconductivity measurements continue, <br />i, The Annual Hydrologic Report is complete. Analysis of the data indicates that <br />the Bear Coal Company operation has not resulted in any degradation of surface <br />or ground water resources. <br />If you have any questions, feel free to call me. <br />I~ Sincerely, <br />Brent Anderson <br />Reclamation Specialist <br />BA/sak <br />8411E <br />~; <br />I <br />~~ 423 Centennial Building, 1313 Sherman Street <br />n ,~ <br />°~:.: <br />} =:;; <br />:~F,;lj~ <br />Tel.
