The Discharger has determined that the reduction in C.dubia survival in this test was caused by plant upset <br /> due to bringing the plant online after a 4 month hiatus in operation that was needed to repair damage from <br /> significant vandalization of plant infrastructure. <br /> i. RPA. No dilution has been granted for chronic whole effluent toxicity. Chronic <br /> toxicity testing results exceeding 1.3 chronic toxicity units (TUc) (as <br /> 100/NOEC) and a percent effect at 100 percent effluent exceeding 25 percent <br /> demonstrates the discharge has a reasonable potential to cause or contribute <br /> to an exceedance of the Basin Plan's narrative toxicity objective. <br /> Table F-10, above, shows chronic toxicity testing conducted between February <br /> 2015 and June 2018. The effluent has had periodic exceedances of the toxicity <br /> trigger. As a result, the Discharger conducted three Toxicity Reduction <br /> ATTACHMENT F- FACT SHEET F-31 <br />
