- TRC = Total Residual Chlorine Samples 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 (25.0 +/- 1.0oC) in a warm water bath.
Aliquots of Outfall 101 and Intake samples were UV-treated through a 40-watt Smart UV Sterilizer (manufactured by Emperor Aquatics, Inc.) for 2 minutes.

Appendix A ADDITIONAL TOXICITY TEST INFORMATION
SUMMARY
OF METHODS
- 1. Pimephales 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
- 1. 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 used to control interference of fish pathogens. This treatment method was approved on November 23, 2015 by the State of Tennessee in a letter from Jessica Murphy to Terry Cheek, Senior Manager of TVA Water Permits, Compliance, and Monitoring.
