The plant has a water allocation <br />froniLake POI,ell for 34,100 acre-feet per year; .the maximum use at <br />present is 23,OOU acre-feet. <br /> <br />At the plant site are 1110 acres of evaporation ponds, with a total <br />capacity of 1,000 acre-feet. The newer ponds are lined with Hypalon. <br />The sa;linity of the water in the ponds is. between 5,000 and 25,OOU <br />milligrams per liter. <br /> <br />In addition to evaporation, wastewater from the generating.plants <br />is also used for dust suppression, and to slurry bottom ash to a.disposal <br />site.
