• Loading Station <br />Product is shipped from the site in bulk transport trucks. <br />Loading from the storage building is by mechanical conveyors. The <br />110 foot truck scale is included in the loading station for <br />control of operations and final accounting. <br />Dust collection systems are provided for the conveyors and the <br />truck load-out area. <br />Evaporation Pond <br />A ten acre evaporation pond has been provided for containment of <br />spills and disposal of waste streams from mining and process <br />operations (Figure 2-2). The pond consists of two compartments of <br />• 3 and 7 acres. The three acre compartment will contain any plant <br />spills or excess process solution overflow. The solutions <br />collected in this compartment will be pumped back to the plant for <br />recycling. The seven acre compartment will contain waste streams <br />such as cooling tower blowdown and water softener waste brine and <br />will not be recycled. The process waste compartment (three acre) <br />has a 150 gpm submersible sump pump to return plant spills to the <br />process. No permanent pump will be required for the waste <br />compartment; rather, a portable unit can be used as required. <br />The pond has a double liner with a leak detection system. The <br />primary liner (top) is 60 mil. high density polethylene (HDPE). <br />The secondary liner is 40 mil. HDPE. A HDPE drainage netting was <br />• used between the two liners to assist flow of potential leakage <br />11 <br />
