-2- Proposed Decision Colorado Coal Mining Company Colorado Coal Mine No. 1 The Colorado Mined Land Reclamation Division proposes to partially approve, with stipulations, an application for a permit to conduct coal mining operations submitted by Colorado Coal Mining Company (GCMG) for the Colorado Coal Mine No. 1. The partial approval in this case refers to that part of the application referred to as the "dry mine plan" by CCMC, as defined later in this document. The approval decision is based on a finding that the proposed operation will comply with all requirements of the Colorado Surface Coal Mining Reclamation Act, C.R.S. 1973, as amended, 34-33-101 et seg., and the Regulations promulgated pursuant to the Act. The permit application and the stipulations will become a binding part of the permit upon approval. The stipulations for Colorado Coal Mine No. 1 are as follows: List of Stipulations Stipulation No. 1 THE PERMITTEE SHALL ESTABLISH A TOTAL OF FIVE SURFACE WATER MONITORING STATIUNS AT THE MINING SITE. THESE SHOULD BE LOCATED AT THE FOLLOWING POINTS: UPSTREAM OF THE MINING OPERATION ON THE 1~1HITLAND HNU GURDON ARROYOS AfdD THE UNNAMED TRIBUTARY OF THE MAITLAND ARROYO AND DOWNSTREAM OF THE MINING OPERATION ON THE MHITLAND ANU GORDON ARROYOS. THESE FIVE STATIUNS SHALL EACH BE MONITORED IN THE FOLLOWING MANNER: 1) A DAILY RECORD OF THE OCCUKRENCE OF FLOWS IN ALL STRENM DRAINAGES (e. g. WAS THERE ANY FLOW?); 2) N DAILY UEPTH OF WATER READING; 3) A WEEKLY MEASUREINENT OF PEAK FLOWS; 4) MONTHLY FIELD MEASUREI4ENTS OF pH, ELECTKO-CONDUCTIVITY, AND TEMPERATURE DURING A PERIOD OF SNOWMELT AND/OR DURING THE FIRST PRECIPITATION EVENT OCCURRING IN THE MONTH; AND 5) A MINIMUM OF THREE WATER QUALITY SAMPLES FOR EACH OF THE STATIONS SHALL BE COLLECTED ANNUALLY. ONE SHALL BE COLLECTED DURING SNOWMELT, UNE DURING A PRECIPITATION EVENT IN MIDSUMMER, AND ONE UURING A PRECIPITATION EVENT AT THE END OF SUMMER. FIELD PARAMETERS OF pH, ELECTRO-CUNUUCTIVITY, TEMPERATURE, AND FLOW SHALL BE TAKEN PRIOR TO SAMPLING AS DESCRIBED ABOVE. THEN THE SAMPLES MUST BE ANALYZED IN A TIMELY MANNER FOR THE FOLLOWING PARAMETERS (TOTAL ION CONCENTRATIONS IN mg/1):
