X <br /> Two valves, one inside the containment area and one external to the containment area, will be <br /> installed. Their respective functions are: <br /> Shut down due to catastrophic failure. The internal valve shall be closed immediately to prevent <br /> liquid leakage in the containment area. The reasonably anticipated time required in the event of <br /> a disastrous failure is 1 minute, but we double the time to 2 minutes for an additional safety factor. <br /> Valves shall manually close in case catastrophic failure includes loss of electrical power. Circuit <br /> will only operate when staffed. <br /> Non-operating shutdown is when both internal and external valves are closed. <br /> Section 3b - Secondary Containment: <br /> A secondary containment perimeter shall be constructed for all liquid handling, storage, and <br /> transfer devices and mechanisms to process water or slurry mixtures in various percent <br /> concentrations. The subject secondary containment covers an area of 100 feet long, 19 feet wide, <br /> and 24 inches deep. The secondary containment volume is 27,121 US Gallons. Diagrams of <br /> Secondary Containment are in Section 4, Diagram 3 "Secondary Containment". Values for Tables <br /> 1, 2, 3 are derived from diagram 3 noted. <br /> Table 1: Specific Operating Areas of Process Circuit Volume with Containment Values <br /> Containment Area Description Volume(cf) Capcity(gal) <br /> Ball Mill Containment Secondary Containment 611 4,567 <br /> Ball Mill Containment Process Holding Capacit' 239 1 788 <br /> %Containment 255% <br /> Deister Table 01 Secondary Containment 404 3 022 <br /> Deister Table 01 Process Holding Capacity 25 187 <br /> %Containment 1616% <br /> Deister Table 02 Secondary Containment 356 2 663 <br /> Deister Table 02 Process Holding Capacity 25 187 <br /> %Containment 1424% <br /> Deister Table 03 Secondary'Containment 348 2.603 <br /> Deister Table 03 Process Holding Capacity 25 187 <br /> Containment 1392% <br /> Concentrate ConditioningPress Secondary Containment 255 1.908 <br /> Concentrate Conditioning Press Process Holding Capacity 118 881 <br /> %Containment 216% <br /> Process Water&Tailings Conditioning'Pre!Secondary Containment 1 652 12.359 <br /> Process Water&Tailings Conditioning Pre!Process Holding Capacity 804 6,017 <br /> %Containment 205% <br /> 5 <br /> 1900 MAIN ST, UNIT 1 i PO BOX 1030 1 OURAY CO 81427 <br />
