The testing shall be conducted as specified in EPA 600/4-91-002, or <br /> later amendment. Chronic toxicity samples shall be collected at the discharge of the wastewater <br /> treatment plant prior to its entering Dredger Cut. 24-hour composite samples shall be <br /> representative of the volume and quality of the discharge. Time of collection samples shall be <br /> recorded. The effluent tests must be conducted with concurrent reference toxicant tests. Monthly <br /> laboratory reference toxicant tests may be substituted upon approval. Both the reference toxicant <br /> and effluent test must meet all test acceptability criteria as specified in the chronic manual. If the. <br /> test acceptability criteria are not achieved, then the Discharger must re-sample and re-test within <br /> 14 days.
