Hennin Uk Environmental Spe ' II, Aquatic Toxicology Branch (ATB) Subject: Whole effluent toxicity test results Huffman Finishing NPDES Permit # NC0025135/001 Caldwell County Division of Water Resources The aquatic toxicity test using flow -proportional composite samples of effluent discharged from the Huffman Finishing has been completed. Huffman Finishing has a permitted effluent discharge of 0.25 million gallons per day (MGD) entering Catawba River (7Q10 of 40 CFS). Whole effluent samples were collected on March 8 and March 10 by Tim Heim for use in a chronic Ceriodaphnia dubia pass -fail toxicity test. The test passed. Toxicity test information follows. Test Type 3-Brood Ceriodaphnia dubia chronic pass -fail Test Result Pass Test Concentrations 0.96% Control Survival 100% Control Mean Reproduction 24.3 neonates Test Treatment Survival 91.7% Treatment Mean Reproduction 22.2 neonates First Sample pH 7.72 SU First Sample Conductivity 4380 micromhos/cm First Sample Total Residual Chlorine <0.2 mg/L Second Sample pH 7.66 SU Second Sample Conductivity 4300 micromhos/cm Second Sample Total Residual Chlorine <0.2 mg/L Test results for the above samples indicate that the effluent would not be predicted to have water quality impacts. These samples were split and tested by Meritech, Inc. (Meritech). The chronic Ceriodaphnia dubia pass/fail test run by Meritech resulted in a pass.
