Peabody Sage Creek Mining, LLC Page 4 0514/2014 responsible for enforcing CDPS permit conditions. 6. Parameters to be Based on a Memorandum of Understanding between the sampled for NPDES CDPS permits CO- Division of Reclamation, Mining and Safety and the Water reporting 0044776 Quality Control Division (WQCD), the WQCD will be responsible for enforcing CDPS permit conditions. The Foidel Creek Mine Reported the following exceedances to the CWQCD in discharge monitoring reports: July 2013 - TSS 30 day average and the daily max was exceeded at Outfalls 001, 002, 003, and 007. Based on alternate TSS standards due to heavy rainfall events, only 7. CDPS discharge Outfall 002 exceeded the TSS alternate limit. limitations CDPS permits CO- 0044776 September 2013 — TSS daily max was exceeded at Outfall 001. Based on a Memorandum of Understanding between the Division of Reclamation, Mining and Safety and the Water Quality Control Division (WQCD), the WQCD will be responsible for enforcing CDPS permit conditions.
