III IIIIIIIIIIIII III <br />United States Department of the Interior <br />OFFICE OF SURFACE MINING <br />Reclamation and Enforcement <br />BROOKS TOWERS <br />1020 ISTH STREET <br />DENVER, COLORADO 80202 <br />OFFICE OF THE REGIONAL DIRECTOR <br />JAN 22 ;:,, <br />Mr. David Shelton <br />Director <br />Mined Land Reclamation <br />Department of Natural Resources <br />1313 Sherman St. <br />Denver, Colorado 80203 <br />Dear M~~~§In'~n: <br /> <br />Jr.rl zc, r~s1 <br />Mi~1f:D LP,PJD RECLAP~ATIOi) <br />Colo. Dept. c•f Natural Rese:lrces <br />This office has reviewed Northern Coal Company's response to special <br />stipulation 1128, attached to the Wilson-Loudy Loadout approval package. <br />Stipulation 1128 required that Northern submit a plan to monitor and <br />assess the impacts of the loadout on groundwater quality. <br />Our staff hydroJ.ogists believe that since Utah International's GBB-3 <br />well is not properly completed, data taken from this well or any new <br />well located down gradient from and proximal to well GBB-3 would probably <br />be inappropriate. Leakage from around the concrete seal of the GBB-3 well <br />may influence the dar_a taken from nearby wells, and thus not depict actual <br />overall groundwater quality. We, therefore, propose that well HWL/OA-2 <br />be drilled 300 feet upgradient from well GBB-3. <br />Northern Coal Company should arrange for the additional quarterly analysis <br />of any parameter(s) from within the first year suite of analyses that may <br />be identified by the regulatory authority as being a potential problem. <br />In addition, we believe that the bicarbonate ion should be included in the <br />first year suite of analyses. <br />Hopefully, this review is in agreement with your findings. Please send <br />our office a copy of your final response to Northern Coal Company. <br />Sincerely, <br />' ~ <br />1- <br />~lz._~ <br />DONALD A. CRANE <br /> <br />
