Prepared by Energy Northwest Environmental Services, January 2023 Energy Northwest Columbia Generating Station 2022 Post Season Fish Collection Report The purpose of this report is to document fish collection activities on the part of Energy Northwest (ENW) during the 2022 calendar year and to verify that the activities were following the Endangered Species Act section 7(a)(2) Biological Opinion for the Columbia Generating Station (NMFS No: NWR/2011/05286) issued March 10, 2017. Also included is a discussion on changes in CGS operations during the 2022 calendar year that had the potential to affect CGS effluent discharges to the Columbia River.
Fish Collection Columbia Generating Station (CGS) is required to collect and analyze fish samples from locations near the CGS effluent discharge in the Columbia River and from a control location, typically the Snake River. The samples are analyzed for radioactive content with the purpose of determining what impact, if any, CGS operation may have on Columbia River fish. The requirements specify collection of one anadromous and two resident fish species from both locations. The fish collection activities are to be performed in accordance with the Endangered Species Act section 7(a)(2) Biological Opinion for the Columbia Generating Station.
Resident Species Collection Columbia River The two resident fish species collected from the Columbia River in 2022 were walleye and small mouth bass.
Energy Northwest (ENW) personnel collected one small mouth bass on 10/17/2022 from the shoreline near CGS and the Tower Make Up (TMU) pumphouse. GPS coordinates were recorded as 46° 28' 18.11"N, 119° 15' 54.2"W and water temperature was measured at 19.1 degrees Celsius. The fish was caught using hook and line techniques that targeted bass. On 10/15/2022, one Walleye was caught. GPS coordinates were recorded as 46° 27' 10.03"N, 119° 15' 48.97"W and water temperature was measured at 18.9 degrees Celsius. The fish were caught using hook and line techniques that targeted Walleye. Fishing techniques used to collect the resident species were in accordance with the Washington Department of Fish and Wildlife (WDFW) freshwater fishing rules for the resident species of interest.
Snake River The resident fish from the Snake River serve as controls and were obtained by local fisherman donation. The local fisherman collected two Walleye and one small mouth Bass on 11/12/2022 from GPS coordinates 46° 14' 14.72"N, 118° 58' 30.05"W, using hook and line techniques. The Snake River temperature was 18.3 degrees Celsius.
Anadromous Species Collection The anadromous species collected from the Snake and Columbia Rivers was Chinook Salmon. Authorization to obtain the fish from local hatcheries was provided by the State of Washington Department of Fish and Wildlife in a letter dated 8/11/2022.
Prepared by Energy Northwest Environmental Services, January 2023 One Chinook Salmon from Ringold Springs Hatchery was collected by hatchery personnel on 9/28/2022. The location is at Station-48, GPS coordinates 46°30'18.9"N 119°15'36.4"W and the water temperature was 20.3 degrees Celsius. A net was used to retrieve the Salmon by hatchery personnel.
A Chinook Salmon was provided by Snake River Lyons Ferry Hatchery on 10/11/2022, GPS coordinates 46° 35.848 N 118° 13.439 W and the water temperature was 19.0 degrees Celsius. The salmon was caught by net using hatchery personnel.
Fish Collection Summary Reasonable and prudent measures were utilized to minimize the impact of biological monitoring activities during 2022.
Fish collection was performed using hook and line techniques that targeted the species of interest; electroshock fishing was not performed. No capture or handling of Upper Columbia River (UCR) spring-run Chinook salmon occurred during the year. One Steelhead was caught using hook and line, but it escaped the hook and swam away prior to the fisherman being able to handle it. The Steelhead hook and escape was at GPS coordinates 46°28'0.88"N, 119°15'51.16"W and the river temperature was measured at 18.9 degrees Celsius Summary of Changes to CGS Aqueous Effluent Discharges During the 2022 calendar year, the National Pollutant Discharge Elimination System (NPDES) effluent monitoring as reported on the monthly discharge monitoring reports indicated that all parameters were within permit specifications with no issues or violations. Additionally, whole effluent toxicity testing performed on a quarterly basis showed no statistically significant difference in survival between the control and the acute critical effluent concentration (ACEC, 11% effluent). Continuous halogenation of circulating water with dehalogenation of the blowdown water was implemented on November 6, 2019. This process involves the discharge of additional dehalogenation chemicals as approved by an amendment to the CGS NPDES permit dated 3/19/2019. Implementation of this process has not resulted in any permit violations to date.

Columbia Generating Station December 2021 NPDES Discharge Monitoring Report
REFERENCE:
NPDES Permit No. WA 002515-1 Condition S3.A Please find attached the NPDES Discharge Monitoring Report (DMR) for December 2021.
The initial circulating water blowdown (CWBD) composite sample collected 12/3/21 for NPDES monitoring requirements exhibited higher than normal metals content due to unusual river sediment conditions. A second composite sample collected 12/15/21 had metal concentrations more in line with regular trends. Both sample results are provided.
Furthermore, December 2021 included a one-week maintenance outage (MO2) during which blowdown to the river remained in service. However tower makeup (TMU) flow was below the accuracy of the TMU flow meter. Therefore TMU influent flows for the period 12/6/21 - 12/11/21 are estimated based on CWBD and potable water usage.
All monthly averages for the monitoring parameters were within permit specifications for the month. The report will be submitted electronically to the State of Washington Department of Ecology (Ecology) via Ecologys online reporting system. If you have any questions concerning this information, please contact M Schmitt at (509) 372-5334.

INTRODUCTION Eurofins Environment Testing Northwest, LLC Applied Sciences Laboratory (EETNW -
ASL) conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: January 25, 2022 The test(s) were conducted using:
the fathead minnow (Pimephales promelas)
Note: A revised report is being issued February 11, 2022 to correct the Exhibit numbers.
OVERVIEW OF REGULATORY GUIDANCE The following provides an overview and excerpts of applicable permit specifics, regulatory guidance, and other relevant information. This is intended only as a helpful guide, from a laboratory perspective, for understanding test outcomes. The final responsibility for interpretation of results remains with the client and/or regulatory agency.
The following guidance is taken from EETNW-ASLs reading of the NPDES permit for Energy Northwests Columbia Generating Station in Richland, WA (permit #WA002515-1, effective Nov 1, 2014, expires Oct 31, 2019, modified Feb 8, 2016, and Mar. 19, 2019).
Acute toxicity:
Effluent Limit for Acute Toxicity:
o No acute toxicity detected in a test concentration representing the acute critical effluent concentration (ACEC).
o The ACEC equals 11% effluent.
Compliance with the Effluent Limit for Acute Toxicity:
o Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC.
o The Permittee must determine the statistical significance by conducting a hypothesis test at the 0.05 level of significance (i.e. alpha = 0.05) o If the difference in survival between the control and the ACEC is less than 10 percent, the Permittee must conduct the hypothesis test at the 0.01 level of significance.
o If the test results show a statistically significant difference in survival between the control and the ACEC, and EFSEC has not determined the test result to be anomalous under Section D, and the test is otherwise valid, the result is a violation of the effluent limit for acute toxicity.
Compliance Testing for Acute Toxicity:
o Conduct quarterly acute toxicity testing on the final effluent. (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) o using each of the species and protocols listed on a rotating basis.
6 of 117 Page 3
Response to Noncompliance With an Effluent Limit for Acute Toxicity:
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin additional compliance monitoring within one week of receiving the test results.
Sampling and Reporting Requirements:
o The permittee must collect grab samples must cool the samples to 0 - 6 degrees Celsius during collection and send them to the lab immediately upon completion.
o The lab must begin the toxicity testing no later than 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> after sampling was completed.
o The Permittee must chemically dechlorinate final effluent with sodium thiosulfate just prior to test initiation. Do not add more sodium thiosulfate than is necessary to neutralize the chlorine. Provide in the test report the calculations to determine the amount of sodium thiosulfate necessary The following is taken from the WDOE guidance (WQ-R-95-80, June 2016 revision):
To reduce WET limit violations (and anomalous concentration-response relationships) due to statistical significance that is a Type I error [false positive], we lower alpha when differences in test organism response are small.
Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant

Control 100 6.25 100 11.0 100 25.0 100 50.0 100 100 100 Statistical analysis in accordance with the EPA protocol and WDOE guidance results in:
NOEC = 100 %
LOEC > 100 %
LC50 > 100 %
From the NPDES permit - Effluent Limit for Acute Toxicity: Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC. [ACEC = 11%].
No statistically significant difference between control and ACEC was shown.
Dissolved oxygen concentrations remained at 4.0 mg/L or greater throughout the test period.
Test temperatures remained in the range of 20+/-1 C.
The P. promelas acute test meets Test Acceptability Criteria (TAC) of a minimum 90 percent control survival. Unless referenced above, the tests proceeded without any noted deviations or interruptions that could have affected test results. The testing should be considered valid.
11 of 117 Page 8
REFERENCE TOXICANT TESTS Reference toxicant (reftox) testing is performed to document both initial and ongoing laboratory performance of the test method(s). While the health of the test organisms is primarily evaluated by the performance of the laboratory control, reftox test results also may be used to assess the health and sensitivity of the test organisms. Reftox test results within their respective cumulative summary (Cusum) chart limits are indicative of consistent laboratory performance and normal test organism sensitivity.
The results of the reftox tests indicate that the test organisms were within their respective cusum chart limits based on EPA guidelines. This demonstrates ongoing laboratory proficiency of the test methods and suggests normal test organism sensitivity in the associated client testing.
The P. promelas acute reftox test was conducted using sodium chloride. The data sheets for the reference toxicant tests are provided in Appendix B.
Table 2 summarizes the reference toxicant test results and Cusum chart limits.

INTRODUCTION Eurofins Environment Testing Northwest, LLC Applied Sciences Laboratory (EETNW -
ASL) conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: April 26, 2022 The test(s) were conducted using:
the water flea (Ceriodaphnia dubia)
Note: A revised report has been issued May 19, 2022 to correct ET-C in the Sample Information section to EETNW-ASL.
OVERVIEW OF REGULATORY GUIDANCE The following provides an overview and excerpts of applicable permit specifics, regulatory guidance, and other relevant information. This is intended only as a helpful guide, from a laboratory perspective, for understanding test outcomes. The final responsibility for interpretation of results remains with the client and/or regulatory agency.
The following guidance is taken from EETNW-ASLs reading of the NPDES permit for Energy Northwests Columbia Generating Station in Richland, WA (permit #WA0025151, effective Nov 1, 2014, expires Oct 31, 2019, modified Feb 8, 2016, and Mar. 19, 2019).
Acute toxicity:
Effluent Limit for Acute Toxicity:
o No acute toxicity detected in a test concentration representing the acute critical effluent concentration (ACEC).
o The ACEC equals 11% effluent.
Compliance with the Effluent Limit for Acute Toxicity:
o Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC.
o The Permittee must determine the statistical significance by conducting a hypothesis test at the 0.05 level of significance (i.e. alpha = 0.05) o If the difference in survival between the control and the ACEC is less than 10 percent, the Permittee must conduct the hypothesis test at the 0.01 level of significance.
o If the test results show a statistically significant difference in survival between the control and the ACEC, and EFSEC has not determined the test result to be anomalous under Section D, and the test is otherwise valid, the result is a violation of the effluent limit for acute toxicity.
Compliance Testing for Acute Toxicity:
34 of 117 Page 3
o Conduct quarterly acute toxicity testing on the final effluent. (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) o using each of the species and protocols listed on a rotating basis.
Response to Noncompliance With an Effluent Limit for Acute Toxicity:
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin additional compliance monitoring within one week of receiving the test results.
Sampling and Reporting Requirements:
o The permittee must collect grab samples must cool the samples to 0 - 6 degrees Celsius during collection and send them to the lab immediately upon completion.
o The lab must begin the toxicity testing no later than 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> after sampling was completed.
o The Permittee must chemically dechlorinate final effluent with sodium thiosulfate just prior to test initiation. Do not add more sodium thiosulfate than is necessary to neutralize the chlorine. Provide in the test report the calculations to determine the amount of sodium thiosulfate necessary The following is taken from the WDOE guidance (WQ-R-95-80, June 2016 revision):
To reduce WET limit violations (and anomalous concentration-response relationships) due to statistical significance that is a Type I error [false positive], we lower alpha when differences in test organism response are small.
Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant
SUMMARY
OF TEST RESULTS Exhibit 1 provides a summary of the final test results.
EXHIBIT 1 Summary of Acute Test Results NOEC LOEC LC50 Was a statistically significant difference Species
(%) (%) (%) between control and ACEC shown?
C. dubia 100 > 100 > 100 No Note: acronyms are as defined below.
From the NPDES permit - Effluent Limit for Acute Toxicity: Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC. [ACEC = 11%].
More detailed information is provided in the Results and Discussion section.

ACRONYM DEFINITIONS (from EPA guidance):
NOEC = No Observed Effect Concentration: The highest test concentration that causes no observable adverse effects on the test organisms (i.e. no statistically significant reduction from the control).
LOEC = Low Observed Effect Concentration: The lowest test concentration that does cause an observable adverse effect on the test organisms (i.e. is statistically significant reduction from the control).
LC50 = Lethal Concentration (50%): A point estimate of the test concentration that would cause death in 50 percent of the test population.
SAMPLE INFORMATION Exhibit 2 provides a summary of the sample conditions as received.

- Note: Due to a laboratory error, the sample was not dechlorinated as required by the client permit. The test showed no toxicity, as such, it is EETNW-ASLs professional opinion that this deviation had no significant impact on the test results. WDOE was consulted on this deviation and found it to be acceptable. See email from WDOE in Appendix C.

The specific statistical analysis and CETIS version used for each endpoint evaluation is listed with the statistical outputs included with each test in Appendix A.
If any additional analysis methods were also used, an explanation of the rationale and reference to the source method is included with the presentation of those results below.
Additional guidance was provided by:
Whole Effluent Toxicity Testing Guidance and Test Review Criteria, Washington State Department of Ecology (revised Jun 2016) Pub# WQ-R-95-80.

RESULTS AND DISCUSSION The raw data sheets for all tests are presented in Appendix A.
ACUTE BIOASSAYS Table 1 summarizes the survival data for the C. dubia acute test.
Table 1 Summary of Acute Results C. dubia Sample Percent Survival Concentration (at Test Termination)
(%)
Control 100 6.25 100 11.0 100 25.0 100 50.0 100 100 100 Statistical analysis in accordance with the EPA protocol and WDOE guidance results in:
NOEC = 100 %
LOEC > 100 %
LC50 > 100 %
From the NPDES permit - Effluent Limit for Acute Toxicity: Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC. [ACEC = 11%].
No statistically significant difference between control and ACEC was shown.
Dissolved oxygen concentrations remained at 4.0 mg/L or greater throughout the test period.
Test temperatures remained in the range of 20+/-1 C.
The C. dubia acute test meets Test Acceptability Criteria (TAC) of a minimum 90 percent control survival. Unless referenced above, the tests proceeded without any noted deviations or interruptions that could have affected test results. The testing should be considered valid.

REFERENCE TOXICANT TESTS Reference toxicant (reftox) testing is performed to document both initial and ongoing laboratory performance of the test method(s). While the health of the test organisms is primarily evaluated by the performance of the laboratory control, reftox test results also may be used to assess the health and sensitivity of the test organisms. Reftox test results within their respective cumulative summary (Cusum) chart limits are indicative of consistent laboratory performance and normal test organism sensitivity.
The results of the reftox tests indicate that the test organisms were within their respective cusum chart limits based on EPA guidelines. This demonstrates ongoing laboratory proficiency of the test methods and suggests normal test organism sensitivity in the associated client testing.
The C. dubia reftox test was conducted using sodium chloride. The data sheets for the reference toxicant test are provided in Appendix B.
Table 2 summarizes the reference toxicant test results and Cusum chart limits.

Deviation Approval THIS EMAIL ORIGINATED FROM OUTSIDE THE WASHINGTON STATE EMAIL SYSTEM - Take caution not to open attachments or links unless you know the sender AND were expecting the attachment or the link Good morning Chris, We have a client that would like us to run a deviation by you for approval. The permit states that if chlorine is detected in the sample then we must dechlorinate. The analyst missed this step. The TRC reading was 0.03 mg/L (the reporting limit is 0.02 mg/L) in which we would have dechlorinated to have a reading of < 0.02 mg/L. No toxicity was shown and all of this will be noted in the report, but would this be acceptable to WDOE?

INTRODUCTION Eurofins Environment Testing Northwest, LLC Applied Sciences Laboratory (EETNW -
ASL) conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: August 9, 2022 The test(s) were conducted using:
the fathead minnow (Pimephales promelas)
A revised report was issued September 1, 2022 to fix a formatting issue and to include a note on the missed temperature in the test.
OVERVIEW OF REGULATORY GUIDANCE The following provides an overview and excerpts of applicable permit specifics, regulatory guidance, and other relevant information. This is intended only as a helpful guide, from a laboratory perspective, for understanding test outcomes. The final responsibility for interpretation of results remains with the client and/or regulatory agency.
The following guidance is taken from EETNW-ASLs reading of the NPDES permit for Energy Northwests Columbia Generating Station in Richland, WA (permit #WA002515-1, effective Nov 1, 2014, expires Oct 31, 2019, modified Feb 8, 2016, and Mar. 19, 2019).
Acute toxicity:
Effluent Limit for Acute Toxicity:
o No acute toxicity detected in a test concentration representing the acute critical effluent concentration (ACEC).
o The ACEC equals 11% effluent.
Compliance with the Effluent Limit for Acute Toxicity:
o Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC.
o The Permittee must determine the statistical significance by conducting a hypothesis test at the 0.05 level of significance (i.e. alpha = 0.05) o If the difference in survival between the control and the ACEC is less than 10 percent, the Permittee must conduct the hypothesis test at the 0.01 level of significance.
o If the test results show a statistically significant difference in survival between the control and the ACEC, and EFSEC has not determined the test result to be anomalous under Section D, and the test is otherwise valid, the result is a violation of the effluent limit for acute toxicity.
Compliance Testing for Acute Toxicity:
63 of 117 Page 3
o Conduct quarterly acute toxicity testing on the final effluent. (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) o using each of the species and protocols listed on a rotating basis.
Response to Noncompliance With an Effluent Limit for Acute Toxicity:
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin additional compliance monitoring within one week of receiving the test results.
Sampling and Reporting Requirements:
o The permittee must collect grab samples must cool the samples to 0 - 6 degrees Celsius during collection and send them to the lab immediately upon completion.
o The lab must begin the toxicity testing no later than 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> after sampling was completed.
o The Permittee must chemically dechlorinate final effluent with sodium thiosulfate just prior to test initiation. Do not add more sodium thiosulfate than is necessary to neutralize the chlorine. Provide in the test report the calculations to determine the amount of sodium thiosulfate necessary The following is taken from the WDOE guidance (WQ-R-95-80, June 2016 revision):
To reduce WET limit violations (and anomalous concentration-response relationships) due to statistical significance that is a Type I error [false positive], we lower alpha when differences in test organism response are small.
Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant

ACRONYM DEFINITIONS (from EPA guidance):
NOEC = No Observed Effect Concentration: The highest test concentration that causes no observable adverse effects on the test organisms (i.e. no statistically significant reduction from the control).
LOEC = Low Observed Effect Concentration: The lowest test concentration that does cause an observable adverse effect on the test organisms (i.e. is statistically significant reduction from the control).
LC50 = Lethal Concentration (50%): A point estimate of the test concentration that would cause death in 50 percent of the test population.

SAMPLE COLLECTION AND STORAGE Samples were collected by Energy Northwest personnel. The samples were accepted as scheduled by EETNW - ASL. Chain of Custody and Sample Receipt Records are provided in Appendix C.
The sample was received within the EPA recommended 0 to 6 oC range.
The sample was received within the WDOE required 0 to 6 oC range.
The sample was initially used for test initiation or test solution renewal within the EPA recommended maximum holding time of 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> of sample collection.

(For renewals of a 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> duration acute test)
Following receipt, the samples were stored in the dark at 0 to 6 C until test solutions were prepared and tested.
SAMPLE PREPARATION Samples used during these tests were:
Temperature adjusted prior to test initiation and each daily renewal.
As no Total Residual Chlorine was observed, dechlorination with sodium thiosulfate was not performed.
DATA ANALYSIS The statistical analyses performed for the acute tests were those outlined in Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms, USEPA Office of Water, Fifth Edition (2002), EPA-821-R-02-012, using CETIS.
The specific statistical analysis and CETIS version used for each endpoint evaluation is listed with the statistical outputs included with each test in Appendix A.
If any additional analysis methods were also used, an explanation of the rationale and reference to the source method is included with the presentation of those results below.

RESULTS AND DISCUSSION The raw data sheets for all tests are presented in Appendix A.
ACUTE BIOASSAYS Table 1 summarizes the survival data for the P. promelas acute test.

Control 100 6.25 100 11.0 97.5 25.0 100 50.0 100 100 97.5 Statistical analysis in accordance with the EPA protocol and WDOE guidance results in:
NOEC = 100 %

LC50 > 100 %
From the NPDES permit - Effluent Limit for Acute Toxicity: Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC. [ACEC = 11%].
No statistically significant difference between control and ACEC was shown.
The temperature was not recorded at test termination in the P. promelas test. EPA and WDOE manual states, Temperature and pH are measured at the end of each 24-h exposure period in at least one test chamber at each test concentration and in the control. Temperature should also be monitored continuously or observed and recorded daily for at least two locations in the environmental control system or the samples. The continuous monitoring of the water bath temperatures indicate the temperatures remained in the temperature range of 20 +/- 1 °C. As no toxicity was observed, it is EETNW - ASLs professional opinion that missing the required temperature measurements had no significant impact on test results.
Dissolved oxygen concentrations remained at 4.0 mg/L or greater throughout the test period.
Test temperatures remained in the range of 20+/-1 C.
The P. promelas acute test meets Test Acceptability Criteria (TAC) of a minimum 90 percent control survival. Unless referenced above, the tests proceeded without any noted deviations or interruptions that could have affected test results. The testing should be considered valid.

REFERENCE TOXICANT TESTS Reference toxicant (reftox) testing is performed to document both initial and ongoing laboratory performance of the test method(s). While the health of the test organisms is primarily evaluated by the performance of the laboratory control, reftox test results also may be used to assess the health and sensitivity of the test organisms. Reftox test results within their respective cumulative summary (Cusum) chart limits are indicative of consistent laboratory performance and normal test organism sensitivity.
The results of the reftox tests indicate that the test organisms were within their respective cusum chart limits based on EPA guidelines. This demonstrates ongoing laboratory proficiency of the test methods and suggests normal test organism sensitivity in the associated client testing.
The P. promelas acute reftox test was conducted using sodium chloride. The data sheets for the reference toxicant tests are provided in Appendix B.
Table 2 summarizes the reference toxicant test results and Cusum chart limits.

Deviation Question Hi Chris, We have a client that would like your input on whether or not this test will be acceptable by WDOE. The analyst missed the temperatures at test termination. There was no observed toxicity, we included our temperature log that showed that the water bath was within temperature range, and made note of it in the final report. Would this be acceptable to WDOE?
Thanks Michelle Michelle Bennett Project Manager/ QA Coordinator Eurofins Environment Testing Northwest - ASL (EETNW - ASL)

INTRODUCTION Eurofins Environment Testing Northwest, LLC Applied Sciences Laboratory (EETNW -
ASL) conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: October 25, 2022 The test(s) were conducted using:
the water flea (Ceriodaphnia dubia)
OVERVIEW OF REGULATORY GUIDANCE The following provides an overview and excerpts of applicable permit specifics, regulatory guidance, and other relevant information. This is intended only as a helpful guide, from a laboratory perspective, for understanding test outcomes. The final responsibility for interpretation of results remains with the client and/or regulatory agency.
The following guidance is taken from EETNW-ASLs reading of the NPDES permit for Energy Northwests Columbia Generating Station in Richland, WA (permit #WA0025151, effective Nov 1, 2014, expires Oct 31, 2019, modified Feb 8, 2016, and Mar. 19, 2019).
Acute toxicity:
Effluent Limit for Acute Toxicity:
o No acute toxicity detected in a test concentration representing the acute critical effluent concentration (ACEC).
o The ACEC equals 11% effluent.
Compliance with the Effluent Limit for Acute Toxicity:
o Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC.
o The Permittee must determine the statistical significance by conducting a hypothesis test at the 0.05 level of significance (i.e. alpha = 0.05) o If the difference in survival between the control and the ACEC is less than 10 percent, the Permittee must conduct the hypothesis test at the 0.01 level of significance.
o If the test results show a statistically significant difference in survival between the control and the ACEC, and EFSEC has not determined the test result to be anomalous under Section D, and the test is otherwise valid, the result is a violation of the effluent limit for acute toxicity.
Compliance Testing for Acute Toxicity:
o Conduct quarterly acute toxicity testing on the final effluent. (Jan-Mar, Apr-Jun, Jul-Sep, Oct-Dec) o using each of the species and protocols listed on a rotating basis.
Response to Noncompliance With an Effluent Limit for Acute Toxicity:
96 of 117 Energy NW B5488.pdf Page 3 of 24
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin additional compliance monitoring within one week of receiving the test results.
Sampling and Reporting Requirements:
o The permittee must collect grab samples must cool the samples to 0 - 6 degrees Celsius during collection and send them to the lab immediately upon completion.
o The lab must begin the toxicity testing no later than 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> after sampling was completed.
o The Permittee must chemically dechlorinate final effluent with sodium thiosulfate just prior to test initiation. Do not add more sodium thiosulfate than is necessary to neutralize the chlorine. Provide in the test report the calculations to determine the amount of sodium thiosulfate necessary The following is taken from the WDOE guidance (WQ-R-95-80, June 2016 revision):
To reduce WET limit violations (and anomalous concentration-response relationships) due to statistical significance that is a Type I error [false positive], we lower alpha when differences in test organism response are small.
Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant
SUMMARY
OF TEST RESULTS Exhibit 1 provides a summary of the final test results.

ACRONYM DEFINITIONS (from EPA guidance):
NOEC = No Observed Effect Concentration: The highest test concentration that causes no observable adverse effects on the test organisms (i.e. no statistically significant reduction from the control).
LOEC = Low Observed Effect Concentration: The lowest test concentration that does cause an observable adverse effect on the test organisms (i.e. is statistically significant reduction from the control).
LC50 = Lethal Concentration (50%): A point estimate of the test concentration that would cause death in 50 percent of the test population.

DILUTION WATER The dilution water used was the standard culture water used by EETNW - ASL:
Reconstituted, moderately hard water (as per EPA protocol) with a total hardness of 75 to 105 mg/L as CaCO3 and an alkalinity of 50 to 75 mg/L as CaCO3.
SAMPLE COLLECTION AND STORAGE Samples were collected by Energy Northwest personnel. The samples were accepted as scheduled by EETNW - ASL. Chain of Custody and Sample Receipt Records are provided in Appendix C.
The sample was received within the EPA recommended 0 to 6 oC range.
The sample was received within the WDOE required 0 to 6 oC range.
The sample was initially used for test initiation or test solution renewal within the EPA recommended maximum holding time of 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> of sample collection.

Following receipt, the samples were stored in the dark at 0 to 6 C until test solutions were prepared and tested.
SAMPLE PREPARATION Samples used during these tests were:
Temperature adjusted prior to test initiation and each daily renewal.
As no Total Residual Chlorine was observed, dechlorination with sodium thiosulfate was not performed.
DATA ANALYSIS The statistical analyses performed for the acute tests were those outlined in Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms, USEPA Office of Water, Fifth Edition (2002), EPA-821-R-02-012, using CETIS.
The specific statistical analysis and CETIS version used for each endpoint evaluation is listed with the statistical outputs included with each test in Appendix A.
If any additional analysis methods were also used, an explanation of the rationale and reference to the source method is included with the presentation of those results below.

From the NPDES permit - Effluent Limit for Acute Toxicity: Compliance with the effluent limit for acute toxicity means the result of the testing show no statistically significant difference in survival between the control and the ACEC. [ACEC = 11%].
No statistically significant difference between control and ACEC was shown.
Dissolved oxygen concentrations remained at 4.0 mg/L or greater throughout the test period.
Test temperatures remained in the range of 20+/-1 C.
The C. dubia acute test meets Test Acceptability Criteria (TAC) of a minimum 90 percent control survival. Unless referenced above, the tests proceeded without any noted deviations or interruptions that could have affected test results. The testing should be considered valid.

REFERENCE TOXICANT TESTS Reference toxicant (reftox) testing is performed to document both initial and ongoing laboratory performance of the test method(s). While the health of the test organisms is primarily evaluated by the performance of the laboratory control, reftox test results also may be used to assess the health and sensitivity of the test organisms. Reftox test results within their respective cumulative summary (Cusum) chart limits are indicative of consistent laboratory performance and normal test organism sensitivity.
The results of the reftox tests indicate that the test organisms were within their respective cusum chart limits based on EPA guidelines. This demonstrates ongoing laboratory proficiency of the test methods and suggests normal test organism sensitivity in the associated client testing.
The C. dubia reftox test was conducted using sodium chloride. The data sheets for the reference toxicant test are provided in Appendix B.
Table 2 summarizes the reference toxicant test results and Cusum chart limits.
