Past monitoring included the Colorado River quality and creek flows in Cottonwood and Rapid Creeks. Surface water monitoring locations are shown on Exhibit 56. Sediment pond discharge will be monitored only when pond dewatering occurs as a result of a 10-year, 24-hour event or lesser event. A grab sample will be taken from the pond discharge. Mine dewatering discharge points and pond discharges will be sampled in accordance with the National Pollutant Discharge Elimination System governed by the State of Colorado and the U.S. Environmental Protection Agency. The samples will be tested for the parameters listed in Table 18-1. 18-1 7-7-99 VOL 5 Tab 18
