Item 1. Whole Effluent Toxicity (WET) Testing - Quarterly: A definitive 48-hour acute test using two test species: (1) Daphnid (Ceriodaphnia dubia) and (2) Fathead Minnow (Pimephales promelas). Toxicity testing will be performed during the months of January, April, July and October. The tests will follow the specifications in Attachment A to NPDES Permit No. NH0100960 or latest method revision. The (WET) testing results are to be submitted to the WRBP by the 30th day after the test is begun. Item 2. Chemical Analysis: A chemical analysis of the effluent and diluent shall be performed for the parameters listed in (Section V of Attachment A to the NPDES Permit) in conjunction with the WET testing or latest method revision. The results of the chemical analysis are to be submitted to the WRBP by the 30th day after the test is begun. The results of the Total Suspended Solids (TSS) and Ammonia tests are to be submitted by e-mail, if required, in advance of the full report in order to reach the WRBP no later than the 7th day of the month following the month of the test. Item 3. Repeat (WET) Testing and Chemical Analysis: If the diluent proves to be toxic to either one of the test species, the State may request that a repeat test be conducted within fourteen (14) days of the first test. The test will follow the specifications in Attachment A to NPDES Permit. The results are to be included with the original report and submitted to the WRBP by the 30th day after the repeat test is begun. A repeat required due to QA/QC failure or lab error shall be performed at no cost to the State.
