NPDES Permit Number AL0025852 Page 27 of 30 (I) For testing with P. promelas:, effluent toxicity tests with control survival of less than 80% or ifdry weight per surviving control organism is less than 0.25 mg; (2) For testing with C. dubia:, if the number of young per surviving control organism is less than 15 or if less than 60% of surviving control females produce three broods; or (3) If the other requirements of the EPA Tcst Procedure are not met. c. In the event of an invalid test, upon subsequent completion of a valid test, the results of all tests, valid and invalid, are to be reported to the Dcpartment along with an explanation of the tests performed and the test results. d. At Outfall 0011, toxicity tests shall be conducted for the duration of this permit in the months of December and April. At Outfall 0031, toxicity tests shall be conductcd on a quarterly basis for the duration of this permit. Should results from the toxicity tests indicate that either Outfall 0011 or Outfall 031 exhibits chronic toxicity, then the Permittee must conduct the follow-up testing described in Part IV.BA.a. 3. Reporting Requirements a. The Permittee shall notify the Department in writing within 48 hours after toxicity has been demonstrated by the scheduled testis). b. Biomonitoring test results obtained during each monitoring period shall be summarized and reported using the appropriate Discharge Monitoring Report (DMR) form approved by the Department. In accordance with Section 2 of this part, an effluent toxicity report containing the information in Sections 2 and 6 shall be included with the DMR. Two copies of thc test results must be submitted to the Department no later than 28 days after the month that tests were performed. 4. Additional Testing Requirements a. Ifchronic toxicity is indicated (i.e., noncompliance with permit limit), then the Permittee must perform two additional valid chronic toxicity tests in accordance with these procedures to determine the extent and duration of the toxic condition. The toxicity tests shall run consecutively beginning on the first calendar week following the date that the Permittee became aware of the permit noncompliance. The results of these follow-up tests shall be submitted to the Department no later than 28 days following the month the tests were performed. b. After evaluation of the results of the follow-up tests, the Department will determine if additional action is appropriate and may require additional testing and/or toxicity reduction measures. The permittee may be required to perform a Toxicity Identification Evaluation (TIE) and/or a Toxicity Reduction Evaluation (TRE). The TIE/TRE shall be performed in accordance with the most recent protocols and guidance outlined by EP A (e.g., EP Al600/2-88/062, EP Al600/R-92/080, EPAl600/R·91·003, EP Al600/R-92/081, EPAl833/B·99/022, and/or EP Al600/6-911005 F) 5. Test Mcthods The tests shall be performed in accordance with the latest edition of the "EPA Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms." The Larval Survival and Growth Test, Method I000.0, shall be used for the fathead minnow (Pimephales promelas) test and the Survival and Reproduction Test, Method 1002.0, shall be used for the c1adoceran (Ceriodaphnia dubia) test. 6. Effluent Toxicity Testing Reports The following information shall be submitted with each DMR unless otherwise directed by the Department. The Department may at any times suspend or reinstate this requirement or may decrease or increase the frequency of submittals. a.
