0 should failures occur. These monitoring systems are noted in Table 1 (for designated chemicals) and discussed herein by EPF and watershed. A summary of system alarms for the critical EPFs is found in Appendix J. If a specific EPF is not discussed relative to monitoring/alarms, none exist at present. Information presented in Appendix B also discusses monitoring of some EPFs in the context of spill prevention containment and control. Countermeasures in the event of releases also are discussed in Appendix B. 5.5.1 Arkansas River Watershed No. 5 Shaft Pump Station: The monitoring and alarm systems for the No. 5 Shaft pump station are detailed in Appendix D. In addition to the systems described, the station is visually checked. A groundwater monitoring well (#5 Shift Monitoring Well) has been installed adjacent to the pump station to monitor the quantity and quality of water at No. 5 Shaft. Storke Wastewater Pump Station: Appendix F details the monitoring and alarm systems for the Storke wastewater pump station. As with the No. 5 Shaft pump station, the Storke wastewater pump station is checked visually by designated employees. A stand-by generator to handle the small pump sets also is available at this EPF in case of a total power failure. • 5.5.2 Eagle River Watershed No. I Dam: Robinson Tailing Impoundment: As discussed, the No. 1 Dam was reconfigured, stabilized, and reseeded. Monitoring of this EPF is conducted visually by various mine personnel. Robinson Reservoir and Pump Station: Monitoring of this EPF is both visual and mechanical. The facilities, particularly the pump return station, are checked visually. As with the other pump stations at Climax, a system alarm is connected telemetrically to the mill control room should pump failure occur. A visual text alarm shows on the mill control room computer when one of the pumps at the pump station ceases operation. In addition, an audible alarm sounds in the mill control room when the water level falls below 28 feet in the process water tanks. Additional information is found in Appendix E Eagle Park Reservoir and Dam: As discussed in some detail previously, the Eagle Park Reservoir is being converted into a fresh water storage impoundment. However, it remains an EPF for upstream potential sources of contamination. It is monitored visually. • Eagle Park Reservoir Seepage Collection and Pump Station: This seepage return station is checked by mine personnel. In addition, a beacon alarm is situated atop the dam to alert 33
