Process wastewater discharges All discharges and activities authorized by this permit must be consistent with the terms and conditions of this permit.The discharge of any of the following pollutants more frequently than, or at a level in excess of that identified and authorized by this permit violates the terms and conditions of this permit.There shall be no discharge of wastewater of radioactive materials in excess of the limitations on radioactive effluents established by the Nuclear Regulatory Commission in the facility operation license and in 10 CFR Parts 20 and 50.Beginning on the effective date of this permit, the Permittee is authorized to discharge circulating cooling water blowdown, service water system blowdown, and radioactive wastewater treatment system effluent, to the Columbia River at the permitted location subject to complying with the following limits: Effluent Limits for Circulating Water Blowdown:

Outfall 001 Latitude 46.47139 Longitude 119.26250 Parameter Average Monthly a Maximum Daily b Flow 5.6 million gallons/day (mgd) 9.4 (mgd)Total Residual Halogen c Not Applicable 0.1 milligrams/liter (mg/L)Chromium (Total) 8.2 pg/L 16.4 pg/L Zinc (Total) 53 pg/L 107 pg/L Polychlorinated biphenyl No discharge No discharge compounds (PCBs)The 126 priority pollutants (40 No detectable amount No detectable amount CFR 423 Appendix A) contained in chemicals added for cooling tower maintenance, except chromium and zinc Minimum Maximum pH d 6.5 standard units (SU) 9.0 SU The effluent limit for acute toxicity is: No acute toxicity detected in a test concentration representing the acute critical effluent concentration (ACEC).The ACEC means the maximum concentration of effluent during critical conditions at the boundary of the acute mixing zone, defined in Section 1 .B of this permit. The ACEC equals 11% effluent.

See S13 for more information.

Page 7 of 47 Permit No. WA002515-1 Effluent Limits for Circulating Water Blowdown:

Outfall 001 Latitude 46.47139 Longitude 119.26250 a Average monthly effluent limit means the highest allowable average of daily discharges over a calendar month. To calculate the discharge value to compare to the limit, you add the value of each daily discharge measured during a calendar month and divide this sum by the total number of daily discharges measured.b Maximum daily effluent limit is the highest allowable daily discharge.

The daily discharge is the average discharge of a pollutant measured during a calendar day. This does not apply to pH or temperature.

c The circulating water blowdown isolation valves must be closed during biofouling treatments and remain closed until the concentration of total residual halogen is less than 0.1 mg/L for at least 15 minutes.d When pH is continuously monitored, excursions between. 5.0 and 6.5, or9.0 and 10.0 will not be considered violations if no single excursion exceeds 60 minutes in length and total excursions do not exceed 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> and 30 minutes per month. Any excursions below 5.0 and above 10.0 at any time are violations.

S1.B. Mixing zone authorization Mixing zone for Outfall 001 The paragraphs below define the maximum boundaries of the mixing zones.Chronic mixing zone The width of the chronic mixing zone is limited to a distance of 175 feet (53 meters). The length of the chronic mixing zone extends 100 feet (30 meters)upstream and 308 feet (94 meters) downstream of the outfall. The mixing zone extends from the discharge port to the top of the water surface. The concentration of pollutants at the edge of the chronic zone must meet chronic aquatic life criteria and human health criteria.Acute mixing zone The width of the acute mixing zone is limited to a distance of 18 feet (5 meters) in any horizontal direction from the outfall. The length of the acute mixing zone extends 10 feet (3 meters) upstream and 31 feet (9 meters) downstream of the outfall. The mixing zone extends from the discharge port to the top of the water surface. The concentration of pollutants at the edge of the acute zone must meet acute aquatic life criteria.Available Dilution (dilution factor)Acute Aquatic Life Criteria 9 .. ......Chronic Aquatic Life Criteria _ 93 Human Health Criteria -Carcinogen 93 _Human Health Criteria -Non-carcinogen 9 ,93 Page 8 of 47 Permit No. WA002515-1 S1.C.

The Permittee must sample daily when continuous monitoring is not possible.2 The Permittee must report the instantaneous maximum and minimum pH monthly. Do not average pH values.3 The Permittee must record and report the:* Number of minutes the pH value measured between 5.0 and 6.5 and between 9.0 and 10.0 for each day.* Total minutes for the month.* Monthly instantaneous maximum and minimum pH.If multiple excursions occur during the day, note the duration for each excursion.

If submitting electronic DMRs, include this additional information in the parameter notes.4 Temperature grab sampling must occur when the effluent is at or near its daily maximum Page 10 of 47 Permit No. WA002515-1 Parameter Units & Speciation Minimum Sampling Sample Type Frequency temperature, which usually occurs in the late afternoon.

If measuring temperature continuously, the Permittee must determine and report a daily maximum from half-hour measurements in a 24-hour period. Continuous monitoring instruments must achieve an accuracy of 0.2 degrees C and the Permittee must verify accuracy annually.5 The sampling point for temperature is at the Circulating Water Pumphouse (CWP) until monitoring equipment is operational in the River Pumphouse (RP). The Permittee may maintain temperature monitoring equipment at the CWP for use during maintenance and outages of equipment at the RP. The Permittee must inform EFSEC on the monthly report when the RP is operational, and thereafter when reported results contain data from the CWP.6 1Monthly means once every calendar month.7 Grab means an individual sample collected over a fifteen (15) minute, or less, period.8 A Grab sample may be substituted for 24-Hour composite sampling until equipment installed as required in Section S7.8 is operational.

The Permittee must inform EFSEC on the monthly report of the sample type.9 If the Permittee submits engineering calculations which demonstrate that the regulated pollutants are not detectable in the final discharge by the analytical methods in 40 CFR part 136, annual monitoring is not required.

The Permittee must, at a minimum, sample once in the last year to meet permit renewal application requirements.

See Appendix A to identify the specific pollutants in the priority pollutant groups listed.10 Asbestos grab sampling must occur once during the permit cycle when the circulating water cooling system is operating at an average number of cycles of concentration and only blowdown is being discharged.

Test results must be submitted with the application for permit renewal.11 Volumes of batch releases of water for pond draining may be estimated based on level measurements.

Feed-and-bleed discharges made directly to the blowdown line must be measured by flow meter.12 Prior to commencement of discharges, the Permittee must verify that pH is within specified limits.Measurements must be taken daily while discharge is in progress.13 Samples must represent a typical facility discharge to Outfall 002. The Permittee must collect one sample annually between March 15 -May 15 and one sample annually between September 15 -November 15.14 Monitor all pond influent flows, add, and report total volume for the month on the discharge monitoring report.S2.B. Sampling and analytical procedures Samples and measurements taken to meet the requirements of this permit must represent the volume and nature of the monitored parameters, including representative sampling of any unusual discharge or discharge condition, including bypasses, upsets, and maintenance-related conditions affecting effluent quality.Sampling and analytical methods used to meet the monitoring requirements specified in this permit must conform to the latest revision of the Guidelines Establishing Test Procedures for the Analysis of Pollutants contained in 40 CFR Part 136 (or as applicable in 40 CFR subchapters N [Parts 400-471] or 0 [Parts 501-503])

unless otherwise specified in this permit. EFSEC may only specify alternative methods for parameters without limits and for those parameters without an EPA approved test method in 40 CFR Part 136.

Page 11 of 47 Permit No. WA002515-1 S2.C. Flow measurement, field measurement, and continuous monitoring devices The Permittee must: 1. Select and use appropriate flow measurement, field measurement, and continuous monitoring devices and methods consistent with accepted scientific practices.

2. Install, calibrate, and maintain these devices to ensure the accuracy of the measurements is consistent with the accepted industry standard and the manufacturer's recommendation for that type of device.3. Calibrate continuous monitoring instruments for the following parameters weekly unless it can demonstrate a longer period is sufficient based on monitoring records. The Permittee:

a. May calibrate apparatus for continuous monitoring of dissolved oxygen by air calibration.

b. Must calibrate continuous pH measurement instruments using a grab sample analyzed in the lab with a pH meter calibrated with standard buffers and analyzed within 15 minutes of sampling.c. Must calibrate continuous chlorine measurement instruments using a grab sample analyzed in the laboratory within 15 minutes of sampling.4. Use field measurement devices as directed by the manufacturer and do not use reagents beyond their expiration dates.5. Calibrate flow-monitoring devices at a minimum frequency of at least one calibration per year.6. Maintain calibration records for at least three years.S2.D. Laboratory accreditation The Permittee must ensure that all monitoring data required by EFSEC for permit specified parameters is prepared by a laboratory registered or accredited under the provisions of chapter 173-50 WAC, Accreditation of Environmental Laboratories..Flow, temperature, settleable solids, conductivity, pH, and internal process control parameters are exempt from this requirement.

S2.E. Request for reduction in monitoring The Permittee may request a reduction of the sampling frequency after twelve (12) months of monitoring.

EFSEC will review each request and at its discretion grant the request when it reissues the permit or by a permit modification.

The Permittee must: 1. Provide a written request.2. Clearly state the parameters for which it is requesting reduced monitoring.

3. Clearly state the justification for the reduction.

Page 12 of 47 Permit No. WA002515-1 S3. Reporting and recording requirements The Permittee must monitor and report in accordance with the following conditions.

Falsification of information submitted to Council is a violation of the terms and conditions of this permit.S3.A. Reporting The first monitoring period begins on the effective date of the permit. The Permittee must: 1. Summarize, report, and submit monitoring data obtained during each monitoring period on the electronic Discharge Monitoring Report (DMR)form provided by Ecology within WQWebDMR.

Include data for each of the parameters tabulated in Special Condition S2 and as required by the form.Report a value for each day sampling occurred (unless specifically exempted in the permit) and for the summary values (when applicable) included on the electronic form.To find out more information and to sign up for WQWebDMR go to: http:l/www.ecy.wa.,qov/procqrams/wq/permits/paris/webdmr.

html 2. Enter the "no discharge" reporting code for an entire DMR, for a specific monitoring point, or for a specific parameter as appropriate, if the Permittee did not discharge wastewater or a specific pollutant during a given monitoring period.3. Report single analytical values below detection as "less than the detection level (DL)" by entering < followed by the numeric value of the detection level (e.g. < 2.0) on the DMR. If the method used did not meet the minimum DL and quantitation level (QL) identified in the permit, report the actual QL and DL in the comments or in the location provided.4. Report the test method used for analysis in the comments if the laboratory used an alternative method not specified in the permit and as allowed in Appendix A.5. Calculate average values (unless otherwise specified in the permit) using: a. The reported numeric value for all parameters measured between the agency-required detection value and the agency-required quantitation value.b. One-half the detection value (for values reported below detection) if the lab detected the parameter in another sample for the reporting period.c.

The Permittee may take one additional sample for toxicity testing and wait for notification from EFSEC before completing the additional testing. The Permittee must submit the notification with the report of the compliance test result and identify the reason for considering the compliance test result to be anomalous.

If EFSEC determines that the test result was not anomalous, the Permittee must complete all of the additional monitoring required in this section. Or, If the one additional sample fails to comply with the effluent limit for acute toxicity, then the Permittee must complete all of the additional monitoring required in this section. Or, If EFSEC determines that the test result was anomalous, the one additional test result will replace the anomalous test result.If all of the additional testing in this section complies with the permit limit, the Permittee must submit a report to EFSEC on possible causes and preventive measures for the transient toxicity event, which triggered the additional compliance monitoring.

This report must include a search of all pertinent and recent facility records, including:

Page 29 of 47 Permit No. WA002515-1

a. Operating records b. Monitoring results c. Inspection records d. Spill reports e. Weather records f. Production records g. Raw material purchases h. Pretreatment records, etc.If the additional testing in this section shows a violation of the acute toxicity limit, the Permittee must submit a Toxicity Identification/Reduction Evaluation (TI/RE) plan to EFSEC within sixty (60). days after the sample date (WAC 173-205-100(2)).

S.E. Sampling and reporting requirements

Page 37 of 47 Permit No. WA002515-1 G14. Penalties for violating permit conditions Any person who is found guilty of willfully violating the terms and conditions of this permit is deemed guilty of a crime, and upon conviction thereof shall be punished by a fine of up to ten thousand dollars ($10,000) and costs of prosecution, or by imprisonment in the discretion of the court. Each day upon which a willful violation occurs may be deemed a separate and additional violation.

Any person who violates the terms and conditions of a waste discharge permit may incur, in addition to any other penalty as provided by law, a civil penalty in the amount of up to ten thousand dollars ($10,000) for every such violation.

Each andevery such violation is a separate and distinct offense, and in case of a continuing violation, every day's continuance is deemed to be a separate and distinct violation.

G15. Upset Definition

-"Upset" means an exceptional incident in which there is unintentional and temporary noncompliance with technology-based permit effluent limits because of factors beyond the reasonable control of the Permittee.

An upset does not, include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

An upset constitutes an affirmative defense to an action brought for noncompliance with such technology-based permit effluent limits if the requirements of the following paragraph are met.A Permittee who wishes to establish the affirmative defense of upset.must demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: I. An upset occurred and that the Permittee can identify the cause(s) of the upset.2. The permitted facility was being properly operated at the time of the upset.3. The Permittee submitted notice of the upset as required in Special Condition S3.E.4. The Permittee complied with any remedial measures required under S3.E of this permit.In any enforcement action the Permittee seeking to establish theoccurrence of an upset has the burden of proof.G16. Property rights This permit does not convey any property rights of any sort, or any exclusive privilege.

G17. Duty to comply The Permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Clean Water Act and is grounds for Page 38 of 47 Permit No. WA002515-1 enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application.

G18. Toxic pollutants The Permittee must comply with effluent standards or prohibitions established under Section 307(a) of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish those standards or prohibitions, even if this permit has not yet been modified to incorporate the requirement.

G19. Penalties for tampering The Clean Water Act provides that any person who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more than two (2) years per violation, or by both.If a conviction of a person is for a violation committed after a first conviction of such person under this condition, punishment shall be a fine of not more than $20,000 per day of violation, or by imprisonment of not more than four (4) years, or by both.G20. Reporting requirements applicable to existing manufacturing, commercial, mining, and silvicultural dischargers The Permittee belonging to the categories of existing manufacturing, commercial, mining, or silviculture must notify EFSEC as soon as they know or have reason to believe: 1. That any activity has occurred or will occur which would result in the discharge, on a routine or frequent basis, of any toxic pollutant which is not limited in this permit, if that discharge will exceed the highest of the following "notification levels:" a. One hundred micrograms per liter (100 [tg/L).b. Two hundred micrograms per liter (200 ýtg/L) for acrolein and acrylonitrile; five hundred micrograms per liter (500 pg/L) for 2,4-dinitrophenol and for 2-methyl-4,6-dinitrophenol; and one milligram per liter (1 mg/L) for antimony.c. Five (5) times the maximum concentration value reported for that pollutant in the permit application in accordance with 40 CFR 122.21 (g)(7).d. The level established by the Director in accordance with 40 CFR 122.44(f).

2. That any activity has occurred or will occur which would result in any discharge, on a non-routine or infrequent basis, of a toxic pollutant which is not limited in this permit, if that discharge will exceed the highest of the following "notification levels:" a. Five hundred micrograms per liter (500lag/L).

b. One milligram per liter (1 mg/L) for antimony.c. Ten (10) times the maximum concentration value reported for that pollutant in the permit application in accordance with 40 CFR 122.2 1(g)(7).d. The level established by the Director in accordance with 40 CFR 122.44(f).

Page 39 of 47 Permit No. WA002515-1 G21. Compliance schedules Reports of compliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule of this permit must be submitted no later than fourteen (14) days following each schedule date.

Page 40 of 47 Permit No. WA002515-1 Appendix A LIST OF POLLUTANTS WITH ANALYTICAL METHODS, DETECTION LIMITS AND QUANTITA TION LEVELS The Permittee must use the specified analytical methods, detection limits (DLs) and quantitation levels (QLs) in the following table for permit and application required monitoring unless:* Another permit condition specifies other methods, detection levels, or quantitation levels." The method used produces measurable results in the sample and EPA has listed it as an EPA-approved method in 40 CFR Part 136.If the Permittee uses an alternative method, not specified in the permit and as allowed above, it must report the test method, DL, and QL on the discharge monitoring report or in the required report.If the Permittee is unable to obtain the required DL and QL in its effluent due to matrix effects, the Permittee must submit a matrix-specific detection limit (MDL) and a quantitation limit (QL) to EFSEC with appropriate laboratory documentation.

When the permit requires the Permittee to measure the base neutral compounds in the list of priority pollutants, it must measure all of the base neutral pollutants listed in the table below. The list includes EPA required base neutral priority pollutants and several additional polynuclear aromatic hydrocarbons (PAHs). The Water Quality Program added several PAHs to the list of base neutrals below from Ecology's Persistent Bioaccumulative Toxics (PBT) List. It only added those PBT parameters of interest to Appendix A that did not increase the overall cost of analysis unreasonably.

EFSEC added this appendix to the permit in order to reduce the number of analytical "non-detects" in permit-required monitoring and to measure effluent concentrations near or below criteria values where possible at a reasonable cost.CONVENTIONAL PARAMETERS Pollutant

Detection level (DL) or detection limit means the minimum concentration of an analyte (substance) that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero as determined by the procedure given in 40 CFR part 136, Appendix B.

Page 47 of 47 Permit No. WA002515-1

2. Quantitation Level (OL) also known as Minimum Level of Quantitation (ML) -The lowest level at which the entire analytical system must give a recognizable signal and acceptable calibration point for the analyte. It is equivalent to the concentration of the lowest calibration standard, assuming that the lab has used all method-specified sample weights, volumes, and cleanup procedures.

The QL is calculated by multiplying the MDL by 3.18 and rounding the result to the number nearest to (1, 2, or 5) x l0n, where n is an integer. (64 FR 30417).ALSO GIVEN AS: The smallest detectable concentration of analyte greater than the Detection Limit (DL) where the accuracy (precision

& bias) achieves the objectives of the intended purpose. (Report of the Federal Advisory Committee on Detection and Quantitation, Approaches and Uses in Clean Water Act Programs Submitted to the US Environmental Protection Agency December 2007).3. Soluble Biochemical Oxygen Demand method note: First, filter the sample through a Millipore Nylon filter (or equivalent)

-pore size of 0.45-0.50 urm (prep all filters by filtering 250 ml, of laboratory grade deionized water through the filter and discard).

Then, analyze sample as per method 5210-B.4. NWTPH Dx -Northwest Total Petroleum Hydrocarbons Diesel Extended Range -see http://www.ecy.wa.gov/biblio/97602.html.

6. 1, 3-dichloroprovlene (mixed isomers) You may report this parameter as two separate parameters:

cis-1, 3-dichlorpropropene (10061-01-5) and trans-1, 3-dichloropropene (10061-02-6).

7. Total Benzofluoranthenes

-Because Benzo(b)fluoranthene, Benzo(j)fluoranthene and Benzo(k)fluoranthene co-elute you may report these three isomers as total benzofluoranthenes.

8. Chlordane

-You may report alpha-chlordane (5103-71-9) and gamma-chlordane (510,3-74-2) in place of chlordane (57-74-9).

If you report alpha and gamma-chlordane, the DL/PQLs that apply are 0.025/0.050.

9. PCB 1016 & PCB 1242 -You may report these two PCB compounds as one parameter called PCB 1016/1242.
