This limit only applies to Dischargers that <br /> chlorinate their extracted groundwater. <br /> 2. pH: The pH of the discharge shall not exceed 8.5 nor be less than 6.5. <br /> 3. Acute Toxicity: <br /> a. Representative samples of the discharge, with compliance measured at Monitoring <br /> Location EFF-001 as described in the Authorization to Discharge, shall meet the <br /> following limits for acute toxicity. Bioassays shall be conducted in compliance with <br /> Section V.A of the Monitoring and Reporting Program(Attachment E). <br /> The survival of test fish in 96-hour static renewal bioassays with the discharge shall be <br /> not less than a three sample moving median of 90% survival and a single test value of not <br /> less than 70% survival. <br /> b. These acute toxicity limitations are further defined as follows: <br /> (1) 3-sample median. A bioassay test showing survival of less than 90 percent represents <br /> a violation of this limitation, if one or more of the past two or less bioassay tests show <br /> less than 90 percent survival. <br /> (2) Single sample. A bioassay test showing survival of less than 70 percent represents a <br /> violation of this limitation. <br /> c. Bioassays shall be performed using the most up-to-date USEPA protocol. Bioassays shall <br /> be conducted using rainbow trout as the test species in compliance with Methods for <br /> Measuring the Acute Toxicity of Effluents and Receiving Water to Freshwater and <br /> Marine Organisms, currently Sth Edition(EPA-821-R-02-012), with exceptions granted <br /> 10 <br /> Limitations and Discharge Requirements <br />
