Therefore the sample should not be considered <br />hazardous on the basis of aquatic toxicity per the guidance established in the Polisini & Miller (CDFG 1988) protocol. Per guidance <br />provided in CCR, Title 22, Section 66261.24a.2B.6, samples with an acute 96-hour LC₅₀ value greater than 500 mg/L when measured <br />in soft water with fathead minnows are not identified as toxic hazardous waste to the aquatic environment. <br />96 LC50: <br />95% Lower Confident Limit: <br />LC50 Method: <br />95% Upper Confident Limit: <br />>750 mg/L Linear Interpolation (ICPIN) <br />N/A N/A <br />CA ELAP 1644 • NELAP 4033ORELAP <br />Page 6 of 34
