The Teller County Planning Department has completed its review of the Department of <br /> Reclamation, Mining and Safety(DBMS)required Technical Revision (TR#80)to install a <br /> temporary fresh water line for the High Grade Mill(HGM). <br /> 2. Teller County understands that this modification and subsequent installation is a result of a <br /> water leak found during an inspection at the toe of the East Cresson Overburden Stockpile Area <br /> (ECOSA)on May 23, 2016. The leaked fresh water was captured in the existing storm water <br /> collection system;specifically, in the ECOSA Toe Road BMP 20 Sump,which then flows into the <br /> Rip Rap Ditch,and ends in the larger EMP 020 sediment pond. Staff further understands that on <br /> May 24, 2016 a ditch was dug by CC&V to ensure all freshwater flows directly into the EMP 020 <br /> site, bypassing any other storm water structures. An internal geotechnical inspection was <br /> completed on the entire face of the ECOSA dump and determined the stability of the ECOSA is <br /> not compromised as a result of the leak. Finally, since the leak was discovered CCU has <br /> conducted daily and weekly scans and inspections with the geotechnical, environmental, <br /> projects,and operations departments and no change in conditions has been observed. <br />
