Surface water monitoring consists of flow measurement and sampling of selected surface stations, discharge points and sample sites on a weekly basis from March through June, and on a monthly basis thereafter, until flow ceases. Selected surface stations are equipped with water level re- corders or crest staff gauges for continuous monitoring of flow. Discharge points are also equipped with flow measuring devices. Sample sites are shown in the attached table, 1984 Surface Water Monitoring. At the time of surface water sampling, temperature, pH, electrical conductivity and dis- solved oxygen are measured, along with a visual check for oil and grease. The parameters analyzed for selected surface stations (SSS), discharge points (SDP) and sample sites (SS) are shown in the attached table, 1984 Surface Water Quality Analyses. LIFE-OF-MINE MONITORING PLAN As required by Colorado Rule 4.05.13, CYCC has committed to the moni- toring and reporting of certain data over the life of the mining and recla- mation operations. Copies of the Discharge Monitoring Report (DMR) pre- pared for the NPDES Permit are to be forwarded to the Colorado Department of Health - Water Quality Control Division and the Colorado Mined Land Rec- lamation Division on a quarterly basis. In addition, data collected at two ground water monitor wells (bedrock well 009-79-4 and alluvial well 009-5- 10) are to forwarded to the CMLRD each quarter. Data from the monitor sites shown on the attached map are to be forwarded to the CMLRD on an annual basis. The monitor sites listed below are included in the Annual Hydrologic Monitoring Report.
