Test results shall by reported along with the Discharge Monitoring Report (DMR) submitted for the end of the reporting period when the sample was taken. (i.e., WET testing results for the calendar quarter ending March 31 shall be reported with the DMR doe April 28, etc.) The results shall be submitted on the Acute Toxicity Test report form, available from the Division.

Acute tests will be replacement static tests of al single effluent grab sample. 2. Failure of Test and Division Notification An acute WET test is failed whenever the LCD, which represents an estimate of the effluent concentration which is lethal to 50010 of the test organisms in the time period prescribed by the test, is found to be less or equal to 100% effluent. The penmttee must provide written notification of the failure of a WET test to the Division, al rig with a statement as to whether the Preliminary Toxicity Incident (PTT)/Toxicity Identification Evaluation (TIE) investigation or accelerated testing is being performed. Notification must be received by the Division within 14 calendar days of the demonstration of acute WET in the routine required test. Demonstration means no later than the last day of the laboratory test b. Cbronic WET Testing (See also Part I.B.7.c for WET requirements applicable to both chronic and acute WET testing) 1.
