6.0 Monitoring Systems <br />lqw The Whirlwind Project is located in a relatively remote area and power will initially be <br />supplied from portable generators. Telephone service is via a satellite dish system. This <br />situation is not conducive to establishing an electronic monitoring system that can alert <br />off-site operators of upset conditions. The treatment plant trailer is, however, equipped <br />with a Webmaster Status Indicator System. Once the site obtains more reliable telephone <br />and power service, this system can be setup to provide status information to Energy <br />Fuels' offices in Nucla. The system can provide emergency warnings via telephone and <br />information on flow rates and which units are operating via the Internet or Cell phone <br />service. <br />Until such time that the Webmaster System can be operated effectively, Energy Fuels <br />will have personnel on site when the water treatment system is operating so that any <br />problems may be identified and fixed quickly. Operators will, at a minimum, check the <br />treatment facilities at the start, mid-point, and end of each shift. <br />Operators will be trained to inspect and identify potential problems associated with the: <br />1. Pumping Systems <br />2. Waterlines and Tanks <br />3. Treatment Plant <br />A daily checklist will be developed and used by the operators to ensure that the entire <br />system is inspected thoroughly. Potential problems will be corrected by the plant operator <br />or reported to management for follow-up if the situation cannot be corrected <br />immediately. Monitoring of each of the three treatment system components is discussed <br />below. <br />6.1 Pumping Systems <br />A level sensor will be installed in the Untreated Water Tank that will be interconnected <br />electrically to the mine water pump so that the pump will automatically shut off if the <br />water level reaches the preset maximum level. During exploration, the maximum water <br />level will be established at 3 inches of freeboard, which is equivalent to the 100-year <br />storm event. Once the mine is developed and the ore pad area is constructed so that it also <br />drains into the Untreated Water Tank, the maximum water level will be established at 1.5 <br />feet of freeboard. The additional 1.25 feet of freeboard will accommodate the storm water <br />runoff from the ore pad during a 100-year storm event. <br />The plant operator will be responsible for verifying that all pumps are operating at normal <br />flow rates and that tank volumes are within normal operating ranges. Pumping rates and <br />tank levels will be noted on. the inspection checklist. Unusually high or low pumping <br />rates will be investigated and corrected. Higher rates may be produced if bypass valves <br />are closed. Lower rates could be caused by plugging, cavitation, waterline leaks, or pump <br />• component failure. <br />19
