Report Number: 18-122-0190 Project Description: Whole Effluent Toxicity (WET) Permit Number: AR0037770 effective 07/01/2015

Dear Mr. Chad Ford: The results of this WET (Whole Effluent Toxicity) test are acceptable according to test review criteria. There were no significant deficiencies found in sample handling, test performance, or reporting. The test results are within the limits established by your NPDES permit and were entered into the permittee's records in the database. Results: Fathead minnow: NOEL/CV > 0.007%

Daphnia pulex: NOEL/CV > 0.007% Permit Limit: 0.005% Method: 2021.0 Daphnia pulex Acute Toxicity 2000.0 Pimephales promelas Acute Toxicity Point sources that discharge pollutants must comply with the terms and conditions of NPDES permits. One approach that NPDES permits use to control the discharge of toxic pollutants is to control whole effluent toxicity (WET). Whole effluent toxicity is the aggregate toxic effect of an aqueous sample (e.g., a reference toxicant, an effluent, or a receiving water) measured directly by an aquatic toxicity test. Aquatic toxicity tests are laboratory experiments that measure biological effects (e.g., growth, survival, and reproduction) of a test sample (effluents or receiving waters) on aquatic organisms. In aquatic toxicity tests, organisms of a particular species and age are held in test chambers and exposed to different concentrations of an aqueous sample. Observations are then made at predetermined exposure periods. At the end of the test, the responses of test organisms are used to estimate the effects of the test sample, either in absolute terms or relative terms (i.e., the effects of an effluent in receiving waters).

Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

o Reported value of “0” indicates result below detection limit of 0.02 mg/L • EPA Acute Manual Edition and Date: EPA-821-R-02-012, OCT 2002 (Fifth edition) • EPA Chronic Manual Edition and Date: EPA-821-R-02-013, OCT 2002 (Fourth edition)

2. Laboratory

• Temperature: Average: 25 °C Range: 25± 1°C • Incubator ID: BIO Thermometer ID: 120554

• Light Cycle: 16 hours light/ 8 hours dark • Light intensity: 50-100 foot-candles, average • Control Water: Dilute mineral water made with 20 % Perrier in Nanopure • Dilution Water: Laboratory control water • Pretreatment: none

3. Method 2021.0 Daphnia pulex Acute Toxicity Testing

• Test chambers: 30 mL disposable plastic beakers • Volume per chamber: 25 mL • Number of organisms per chamber: 8 • Number of replicates: 5 • Food: Daphnia pulex are fed 0.15mL Raphidocelis subcapitata (Algae) and YTC solution while

holding prior to testing.

4. Method 2000.0 Pimephales promelas (Fathead minnow) Acute Toxicity Testing • Test chambers: 20 oz. Disposable plastic cups • Volume per chamber: 250 mL • Average number of organisms per chamber: 8 • Number of replicates per concentration: 5 • Food: Fathead minnows are fed 0.15mL Artemia brine shrimp hatched in laboratory during holding,

prior to test twice daily • Acclimation of organisms: Organisms are allowed to reach test temperature. Dilution water is added at

half-hour intervals until organisms are contained in a culture media that consists of 80% dilution water.

5. Reference Toxicity • Reference toxicity tests are performed monthly on each method performed by the laboratory. • Potassium Chloride is used as the reference toxicity chemical • Current chemical id is: CS 6150834

6. Indicate below any other relevant information that may aid in the evaluation of this report. Include any deviations from EPA methodology that were necessary for these tests as well as any sample manipulations which were performed, such as aeration, dechlorination with sodium thiosulfate, etc. and the justification for such manipulations or deviations. Attach additional pages as needed. • None
