Columbia Generating Station June 2020 NPDES Discharge Monitoring Report
REFERENCE:
NPDES Permit No. WA002515-1, Condition S3.A Please find attached the NPDES Discharge Monitoring Report (DMR) for June 2020.
All monitoring parameters were within permit specifications for the month. However, an electronic Distributed Network Architecture (eDNA) issue resulted in parameters that were monitored but not recorded on June 5 and 6; no changes to blowdown occurred during this time. Additionally, the compliance flow meter was declared non-functional from June 27-July 5 and alternate operator logs were used.
The report will be submitted electronically to the State of Washington Department of Ecology (Ecology) via Ecologys online reporting system.

INTRODUCTION Eurofins TestAmerica - Corvallis (ET-C) Aquatic Toxicology Laboratory conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: February 4, 2020 The test(s) were conducted using:
x the fathead minnow (Pimephales promelas)
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 ET-Cs 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:
x 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.
x 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.
x 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:
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin Page 3 of 28
additional compliance monitoring within one week of receiving the test results.
x 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):
x 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.
x 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 results in:
x NOEC = 100 %
x LOEC > 100 %
x LC 50 > 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%].
x No statistically significant difference between control and ACEC was shown.
EPA guidance recommends test temperature to remain at 20+/-1qC for the acute test.
Dissolved oxygen concentrations remained at 4.0 mg/L or greater throughout the test period and test temperatures remained in the range of 20+/-1qC.
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 TEST 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 test 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 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.

The following guidance is taken from ET-Cs 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 March 19, 2019).
Acute toxicity:
x 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.
x 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.
x 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:
o If a toxicity test determines a statistically significant difference in response between the ACEC and the control, the Permittee must begin Page 3 of 24
additional compliance monitoring within one week of receiving the test results.
x 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):
x 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.
x Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant

REFERENCE TOXICANT TEST 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 test 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.

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 ET-Cs 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:
x 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.
x 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.
x 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:

INTRODUCTION Eurofins TestAmerica - Corvallis (ET-C) Aquatic Toxicology Laboratory conducted toxicity testing on sample(s) from Energy Northwest, Richland, Washington.
Testing was initiated on: November 3, 2020 The test(s) were conducted using:
x 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 ET-Cs 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:
x 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.
x 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.
x 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:
Page 3
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.
x 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):
x 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.
x Alpha will be lowered from 0.05 to 0.01 if a 10% difference in an acute test is significant

Control 90 6.25 95 11.0 95 25.0 95 50.0 100 100 95 Statistical analysis in accordance with the EPA protocol results in:
x NOEC = 100 %
x LOEC > 100 %
x 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%].
x 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 and test temperatures remained in the range of 20+/-1qC.
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 TEST 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 test 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.
