Peabody Sage Creek Mining, LLC <br />Peabody Sage Creel. Mine <br />29515 RCR 27 <br />Oak ('reek, Co 30.167 <br />inspection, maintenance, and monitoring activities will continue under Temporary Cessation, <br />with the following modifications or clarifications: <br />• The CDRMS currently inspects the Mine on a monthly basis. Under Temporary <br />Cessation, these inspections will continue, but on a quarterly basis. <br />• Under approved Technical Revision TR09-16, the hydrologic monitoring schedule has <br />been reduced to provide the basis ongoing information required by both the CDRMS <br />and WQCD. No further monitoring reductions are anticipated at this time under <br />Temporary Cessation. <br />• Pond sediment capacity surveys are currently on a 10 -year schedule (given that the <br />contributing drainage areas are reclaimed and well vegetated) and were most recently <br />surveyed in 2016, so this requirement should not be affected by Temporary Cessation. <br />• PSCM currently conducts annual raptor surveys to assess any changes in raptor <br />occupancy and use of the area. Given that there is very limited activity at the site, <br />PSCM requests that this annual survey requirement be suspended during Temporary <br />Cessation. <br />• PSCM coordinates with CPW on annual grouse surveys, focusing primarily on the <br />Seneca Il reclaimed areas, but including portions of the Sage Creek Permit Area. Given <br />CPW's interest in documenting grouse populations and any significant changes over <br />time, PSCM will continue to cooperate with CPW's ongoing survey efforts, so long as <br />they are willing to continue to conduct these surveys. <br />PSCM will notify the CDRMS in advance of any additional proposed backfilling, regrading, re - <br />vegetation, environmental monitoring, underground opening closures, or water treatment <br />activities. <br />d) As indicated in the introductory paragraph, resumption of operations is unlikely to occur <br />anytime in the near future based upon current market conditions and near-term projections. <br />After you have opportunity to review the accompanying information, please feel free to contact me <br />with any questions, or to discuss. We appreciate your consideration and assistance. <br />Best regards, <br />For Peabody Sa reed ining, LLC <br />Jerry ettle n <br />Manager E iro ental Affairs <br />Peabody olor o Operations <br />29515 RC <br />Oak Creek, Colorado 80467 <br />970.870.2712 <br />
