The re ulting IC2s values, for both species were> l 00 percent. Exposure of daphnids to intake samples resulted in no significant difference from the control during this study period. Minnow growth in the intake samples wa significantly lower than the control.

*TRC = Total Residual Chlorine tsamples were collected in two 2.5 gallon cubitainers. Temperature was measured in each cubitainer upon arrival.
- 4. Sample Manipulation: Samples from Outfall 101 and intake were warmed to test temperature (25. O+/- l. 0°C) in a warm water bath.
Alig uots of Outfall l 0 1 and Intake samples were UV -treated through a 40-watt Smart UV Sterilizer (manufactured by Emperor Aquatics, Inc.) for 2 minutes. 3of 90

SUMMARY
I CO CLUSIONS Exposures to samples collected October 04 - 09, 2020 from Outfall I 01 resulted in no toxic effects to fathead minnows or daplu1ids. The resulting IC2s values for both species. were > I 00 percent. Exposure of daphnids to intake samples resulted in no significant difference from the control during this study period. Minnow grovJth in the intake samples was significantly lower than the control. 9 of90
Appendix A ADDITIONAL TOXICITY TEST lNFORMATION
SUMMARY
OF METHODS I . Pimephales promeia 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 djspo able cups, each containing 250-mL of test sol ution.
- 2. Ceriodaphnia dubia Tests were conducted according to EPA-82 1-R-02-013 (October 2002) usjng ten replicates each containing one test organism, per treatment. Test vessels consisted of 30-mL po lypropylene cups each containing 15-mL of test solution.
DEVIATION I MODIFICATIONS TO TEST PROTOCOL I . Pimephales promelas Samples used in the fathead minnow test were exposed to UV light for two minutes prior to introduction of test organisms. UV treatment is u ed to control interference of fi h pathogens. This treatment method was approved on November 23 20 l 5 by the State of Te1messee in a letter from Jessica Murphy to Terry Cheek, Senior Manager of TV A Water Permits, Compliance, and Monitoring,
