TN0026450, OUTFALL 101, JULY, 2005 Attached are two copies of the subject report for submission to the state of Tennessee and a copy of the report for your records. The report provides results of compliance testing using fathead minnows and daphnids. Outfall 101 samples collected July 17-22, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 values for both species were > 100 percent. Exposure of fathead minnows and daphnids to intake samples resulted in no significant differences from controls during this study period. In addition to the routine compliance test, fathead minnows were also tested in Outfall 1.01 and intake samples which were treated using UV exposure for pathogen removal prior to introduction of test organisms. Fish pathogens present in intake water have been the suspected cause of anomalous dose responses and high variability among replicates in previous toxicity testing at Sequoyah. At the time this study was conducted, mortality was not demonstrated in minnows exposed to routine compliance samples. Reduction in growth was statistically significant in UV-treated intake samples. Call me at (256) 386-2755 if you have any questions or comments following your review of the report. Cynthia L.

22. Notes: Outfall 101 samples collected July 17-22, 2005, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 values, for both species, were >

100 percent. Exposure of fathead minnows and daphnids to intake samples resulted in no significant differences from controls during this study period. Fathead minnows were also exposed to UV treated Outfall 101 and intake samples since fish pathogens present in intake water have been the suspected cause of interference (anomalous dose response and high variability among replicates) in previous toxicity testing at Sequoyah. At the time this study was conducted, insignificant mortality occurred in minnows exposed to non-treated and UV treated samples. Reduction in growth was statistically significant in UV treated intake samples. 2

SUMMARY

/ CONCLUSIONS Outfall 101 samples collected July 17-22, 2005, showed no toxic effects to fathead minnows or daphnids. The resulting IC25 values, for both species, were > 100 percent. Exposure of fathead minnows and daphnids to intake samples resulted in no significant differences from controls during this study period.

Fathead minnows were also exposed to UV treated Outfall 101 and intake samples since fish pathogens present in intake water have been the suspected cause of interference (anomalous dose response and high variability among replicates) in previous toxicity testing at Sequoyah. At the time this study was conducted, insignificant mortality occurred in minnows exposed to non-treated and UV treated samples. Reduction in growth was statistically significant in UV treated intake samples. 11

SUMMARY

OF METHODS

1. Pimerphales promelas Tests were conducted according to EPA-821-R-02-013 (October 2002) using four replicates, each containing ten test organisms, per treatment. Test vessels consisted of 500-mL plastic disposable cups, each containing 250-mL of test solution.
2. Ceriodaphnia dubia Tests were conducted according to EPA-821-R-02-013 (October 2002) using ten replicates, each containing one test organism, per treatment. Test vessels consisted of 30-mL polypropylene cups, each containing 15-mL of test solution.

DEVIATIONS / MODIFICATIONS TO TEST PROTOCOL

The PMSD is the minimum percent difference between the control and treatment that can be declared statistically significant in a whole effluent toxicity test. On average, a significant difference occurs for Environmental Testing Solutions, Inc. chronic toxicity tests when a toxicant reduces Ceriodaphnia reproduction by 9.2% from the control. Lower PMSD bound determined by USEPA (10 d percentile) - 11%. Upper PMSD bound determined by USEPA (90' percentile) - 37%. Tle lower and upper bounds were calculated by the USEPA using 393 tests conducted from 33 laboratories for Ceriodaphnia reproduction in chronic reference toxicant tests. USEPA. 2000.

On average, the CV for control reproduction is 6.8% in Environmental Testing Solutions, Inc. Ceriodaphnfa chronic toxicity tests. Lower CV bound determined by USEPA (10' percentile) - 8.9%. Upper CV bound determined by USEPA (90' percentile) - 42% MSD - Minimum Significant Difference PMSD - Percent Minimum Significant Difference PMSD is a measure of test precision. The PMSD is the mnnimum percent difference between the control and treatrnent that can be declared statistically significant in a whole effluent toxicity test. On average, a significant difference occurs for Environmental Testing Sohrtions, Inc. chronic toxicity tests when a toxicant reduces Cerodaphnla reproduction by 9.2% from the control LowerPMSD bound determined byUSEPA(10' percentile) - 11I%. Upper PMSD bound determined by USEPA (90' percentile) - 37%. CT - Central Tendancy (Mean Control Reproduction, CV, or PMSD) Tle lower and upper bounds were calculated by the USEPA using 393 tests conducted from 33 laboratories for Criodaphnia reproduction in chronic reference toxicant tests. 07-12-05new
