Sherman <br />Executive Director <br />Ronald W. Cattany <br />Division Director <br />Natural Resource Tms[ee <br />The Division of Reclamation, Mining, and Safety (DBMS) engineering staff have reviewed the Heit Pit under <br />drain construction report prepazed by Civil Resources, LLC and received at our offices on August 7, 2007. This <br />report describes how the under drain installed, if functioning properly, should meet the ground water table <br />elevation goals of the under drain design approved in technical revision TR-03 to the Heit Pit permit. The <br />construction report reiterates that ground water monitoring will continue at the site as approved in technical <br />revision TR-02. You are reminded that ground water mitigation is required if the ground water table trigger <br />elevations approved in TR-02 are detected through the monitoring data collected. <br />The DBMS by this letter accepts the under drain construction report including the under drain design changes <br />from the original approved design that are described in the construction report and that were the subject of a <br />telephone conversation between me and Brian Brown of Civil Resources on July 2, 2007. <br />If you have any questions, please contact me at (303) 866-4063. <br />Sincerely, <br />~G~ ~~ ~ <br />A11en C.
