1001 in Appendix B. The CDMG monitoring program at the Golden Eagle Mine is presented in Table 1.2-1 Hydrology Monitoring Program and Table 1.2-2 Water Quality Parameter Sample Suites. As a result of site reclamation and Phase II bond release, the monitoring program was reduced to those stations and parameters presented in Tables 1.2-3 and 1.2-4. The following are descriptions of the current sampling stations, their locations, and their purpose. Springs and Seeps The spring and seep monitoring program samples field parameters on springs within a 2 '/z mile radius ofthe underground workings once annually during the late summer ofthe year, to ensure that geohydrologic changes associated with the mine do not diminish the water quantity or quality of springs. Fourteen springs were visited on August 11, 2001 (see Appendix B). Surface Water (streams and rivers) CCS-1: A stream grab sample station located in Ciruela Canyon above the point of Golden Eagle Mine water discharge point of MDGE-1 (Pond 002). It was established to monitor baseline conditions above the discharge point. Data collected during this year are presented inTable A-1. Data (annual minimum, maximum, mean) collected from 1984 are presented in Table A-2. CCS-2: A grab sample station located in Ciruela Canyon below the Golden Eagle Mine facilities area, above the confluence with the Purgatoire River. The station was established to assess potential effects of mine water discharge, the coal refuse disposal area in Ciruela Canyon and the facilities area. Flow and water chemistry measurements are presented inTable A-3. Table A-4 is a summary of data (annual minimum, maximum, mean) for the years 1984 to date. PRS-2: _ _ A grab sample and flow station located on the Purgatoire River above the Golden Eagle surface facilities and downstream from the confluence ofthe North and Middle Forks. This station was selected to establish baseline data above the Golden Eagle Mine. Data collected during this year at this station are presented in Table A-5. Data (annual minimum, maximum, mean) from 1984 to date are presented in Table A-6. PRS-3: A grab sample and flow station located on the Purgatoire River below the Golden Eagle surface facilities, approximately one mile below PRS-2. This station was established to assess potential effects of mining on stream quality and flow. Data collected during this year at this station are presented in Table A-7. Data (annual minimum, maximum, mean) from 1984 to date are presented in Table A-8. IOOOAHRe-~~r/-RPT(292)/April/9, 1001
