a Average monthly effluent limitmeans the highest allowable average ofdaily discharges over a calendar month. To calculate the discharge value to compare to the limit, you add the value ofeach daily discharge measured during a calendar month and divide this sumbythe total number ofdaily discharges measured.
b Maximum daily effluent limit is the highest allowable daily discharge. The daily discharge is the average discharge ofa pollutant measured during a calendar day. Forpollutants with limits expressed inunits ofmass,

c

d calculate the daily discharge as the total mass ofthe pollutant discharged over the day. This does not apply to pH ortemperature. WhenpH is continuously monitored, excursions between 5.0 and 6.0, or 9.0 and 10.0 are notbe considered violations ifno single excursion exceeds 60 minutes in length and total excursions do not exceed 7 hours and 30 minutespermonth. Any excursions below 5.0 and above 10.0 at any time are violations. Compliance with the geometric mean and geometric mean variance is calculated over the dry season (July through October). Compliance withthe limits takes effect beginning withthe 2018 critical season.



### Sl.B. StormwaterDischarges Beginning onthe effective date ofthis permit and lasting through its expiration date, the Permittee is authorized to discharge storm water and non routine and unanticipated discharges approved by Ecology as per Special Condition S.7 from Outfall 004 to ground and through an overflowtie in with Outfall 001. All discharges and activities authorized bythis permitmust be consistent withthe terms and conditions ofthis permit. The Permittee is further authorized to discharge non-process storm water and non routine and unanticipated discharges approved by Ecology as per SpecialPage 8 of52 Permit No. WA000088-4

Condition S.7 through collection points 002 and 003 to the City ofSumner's storm water collection system which discharges to the Stuckey/White River. The Permittee must manage all process storm water discharges via outfall 004 to prevent the discharge of: 1) synthetic, natural, or processed oil or oil-containing products as identified by oil sheens, or 2) floating materials.

The Permittee must submitprior notice, ifpossible, at least ten (10) days before the date ofthe bypass. 2. Bypass is unavoidable, unanticipated, andresults innoncompliance ofthis permit.
This permit authorizes such a bypass only if:

a. Bypass is unavoidable to prevent loss oflife, personal injury, or severe property damage. "Severeproperty damage" means substantial physical damage to property, damage to the treatment facilities which would cause them to become inoperable, or substantial and permanent loss ofnatural resources which canreasonably be expected to occur inthe absence ofa bypass. b. No feasible alternatives to the bypass exist, such as:
• The use ofauxiliary treatment facilities.Page 21 of52 PermitNo. WA000088-4

• Retention ofuntreated wastes. • Stopping production. " Maintenance during normal periods ofequipment downtime, but not if the Permittee should have installed adequate backup equipment in the exercise ofreasonable engineeringjudgmentto prevent a bypass. " Transport ofuntreated wastes to another treatment facility or preventative maintenance), or transport ofuntreated wastes to another treatment facility.

c. The Permittee has properly notified Ecology ofthe bypass as required in Condition S3.E ofthispermit. 3. Ifbypass is anticipated and has the potential to result in noncompliance ofthis permit.

a. The Permittee must notify Ecology at least thirty (30) days before the planned date ofbypass. The notice must contain:

• A description ofthe bypass and its cause. • An analysis ofall known alternatives which would eliminate, reduce, or mitigate the need for bypassing. • A cost-effectiveness analysis ofalternatives including comparative resource damage assessment. • The minimum and maximum duration ofbypass under each alternative. • A recommendation as to the preferred alternative for conducting the bypass. • The projected date ofbypass initiation. • A statement ofcompliance with SEPA. • A request for modification ofwater quality standards as provided for in WAC 173-201A-410, ifan exceedance ofany water quality standard is anticipated. • Details ofthe steps taken or plannedto reduce, eliminate, and prevent reoccurrence ofthe bypass. b. Forprobable construction bypasses, the Permittee mustnotify Ecology of the need to bypass as early inthe planning process as possible. The Permittee must consider the analysis required above during preparation of the engineering report or facilities plan and plans and specifications and must include these to the extentpractical. In cases where the Permittee determines the probable need to bypass early, the Permittee must continue to analyze conditions up to and including the constructionperiod in an effort to minimize or eliminate the bypass.

c. Ecology will consider the following prior to issuing an administrative order for this type ofbypass:Page 22 of52 Permit No. WA000088-4

8 Ifthe bypass is necessary to perform construction or maintenance-related activities essential to meet the requirements of this permit.

8 Iffeasible alternatives to bypass exist, such as the use ofauxiliary treatment facilities, retention ofuntreated wastes, stoppingproduction, maintenance during normal periods ofequipment down time, or transport ofuntreated wastes to another treatment facility.

8 Ifthe Permittee planned and scheduled the bypass to minimize adverse effects onthe public and the environment. After consideration ofthe above and the adverse effects ofthe proposed bypass and any other relevant factors, Ecology will approve or deny the request. Ecology will give the public an opportunity to comment on bypass incidents ofsignificant duration, to the extent feasible. Ecology will approve a request to bypass by issuing an administrative order under RCW 90.48.120.

IfthePage 33 of52 PermitNo. WA000088-4

test does not meet the power standard, the Permittee must repeat the test on a fresh sample with an increased number ofreplicates to increase the power. 

### 513. Chronic Toxicity Sl3.A. Effluent Limit for Chronic Toxicity TheEffluentLimit for Chronic Toxicity is: No toxicity detected in a test concentrationrepresenting the chronic critical effluent concentration (CCEC). The CCEC means the maximum concentration ofeffluent during critical conditions at the boundary ofthe mixing zone, defined in Section S1.B ofthis permit. The CCEC equals 0.77% effluent. 

### Sl3.B. Compliancewith the EffluentLimit for Chronic Toxicity Compliance with the effluent limit for chronic toxicity means the results ofthe testing specified in Subsection D. showno statistically significant difference in response betweenthe control and the CCEC. Ifthe test results show a statistically significant difference in response between the control and the CCEC, the test does not comply with the effluent limit for chronic toxicity. The Permittee must then immediately conduct the additional testing described in SubsectionE. The Permittee will comply with the requirements ofthis section by meeting the requirements ofSubsection E. The Permittee must determine the statistical significance by conducting a hypothesis test at the 0.05 level ofsignificance (Appendix H, EPA/600/4-89/001 ). Ifthe difference inresponse betweenthe control and the CCEC is less than 20%, the Permittee must conduct the hypothesis test at the 0.01 level ofsignificance. Ecology will reevaluate the need for the chronic toxicity li:rp.it in future permits. Therefore, the Permittee must also conduct this same hypothesis test (Appendix H, EPA/600/4-89/001) to determine whether a statistically significant difference inresponse exists between the acute critical effluent concentration (ACEC) and the control. 

### S13.C. Compliance Testing for Chronic Toxicity The Permittee must: 1. Perform the chronic toxicity tests using the CCEC, the ACEC, and a control, or with a full dilution series. 2. Conduct semi-annual chronic toxicity testing onthe final effluent if characterization determines that the effluent limit for chronic toxicity is applicable. Semi-annual testing shall occur in years 2013 through 2017. Each semi-annual period, only for chronic toxicity testing, is defined as JanuaryPage 34 of52 PermitNo. WA000088-4

through June and July through December. Testing must begin within 120 days ofthe effective date ofthe permit. 3. Submit chronic toxicity testing results to Ecology within sixty (60) days after each sampling event. This writtenreport must include the results of hypothesis testing conducted as described in Subsection C. using boththe ACEC and CCEC versus the control. Further instructions ontesting conditions and test report content are in Subsection G below. 4. Perform compliance tests using the following species on a rotating basis and the most recent version ofthe following protocols:

Freshwater Chronic Species Method Test Fathead minnow survival Pimephalespromelas EPA-821-R-02-013 and growth Water flea survival and Ceriodaphnia dubia EPA-821-R-02-013 reproduction Sl3.D. Response to Noncompliance with the Effluent Limit for Chronic Toxicity Ifa toxicity test conducted under Subsection C determines a statistically significant difference inresponse between the CCEC and the control using the statistical test described in Subsection C, the Permittee mustbegin additional testing within one week from the time ofreceiving the test results. The Permittee must: 1. Conduct additional testing each month for three consecutive months using the same test and species as the failed compliance test. 2. Use a series ofat least five effluent concentrations and a control to determine appropriate point estimates. One ofthese effluent concentrations must equal the CCEC. The results ofthe test at the CCEC will determine compliance with the effluent limit for chronic toxicity as described in SubsectionB. 3. Return to the original monitoring frequency in Subsection C after completion ofthe additional compliance monitoring. Anomalous Test Results: Ifa toxicity test conducted under Subsection C indicates noncompliance with the chronic toxicity limit and the Permittee believes that the test result is anomalous, the Permittee may notify Ecologythat.the compliance test result may be anomalous. The Permittee may take one additional sample for toxicity testing and wait for notification from Ecology before completing the additional testing. The Permittee must submitthe notification withthe report ofthe compliance test result and identify the reason for considering the compliance test result to be anomalous. IfEcology determines that the test result was not anomalous, the Permittee must complete all ofthe additional monitoring required inthis subsection. Or,Page 35 of52 Permit No. WA000088-4

Ifthe one additional sample fails to comply with the effluent limit for clu·onic toxicity, then the Permittee must complete all ofthe additional monitoring required in this subsection. Or, IfEcology determines that the test result was anomalous, the one additional test result will replace the anomalous test result. Ifall ofthe additional testing required by this subsection complies with the permit limit, the Permittee must submit a report to Ecology onpossible causes and preventive measures for the transient toxicity event, which triggered the additional compliance monitoring. This report must include a search ofall pertinent and recent facility records, including:


### • Operating records 

### • Monitoring results 

### • Inspectionrecords 

### • Spill reports 

### • Weatherrecords 

### • Productionrecords 

### • Rawmaterial purchases 

## • Pretreatment records, etc

. Ifthe additional testing required by this subsection shows another violation ofthe chronic toxicity limit, the Permittee must submit a Toxicity Identification/Reduction Evaluation (TIIRE) plan to Ecology within 60 days after the sample date (WAC 173-205-100(2)). Sl3.E. Sampling and Reporting Requirements 1. The Permittee must submit all reports for toxicity testing in accordance with the mostrecent version ofEcology PublicationNo. WQ-R-95-80, Laboratory Guidance and Whole Effluent Toxicity Test Review Criteria. Reports must contain bench sheets and reference toxicant results for test methods. Ifthe lab provides the toxicity test data in electronic format for entry into Ecology's database, then the Permittee must send the data to Ecology along with the test report, bench sheets, and reference toxicant results. 2. The Permittee must collect 24-hour composite effluent samples or grab samples for toxicity testing. The Permittee must cool the samples to 0 - 6 degrees Celsius during collection and send them to the lab immediately upon completion. The lab must beginthe toxicity testing as soon as possible but no laterthan 36 hours after sampling was completed. 3. The laboratory must conduct water quality measurements on all samples and test solutions for toxicity testing, as specified inthe most recent version of Ecology PublicationNo. WQ-R-95-80, Laboratory Guidance and Whole Effluent Toxicity Test Review Criteria. 4. All toxicity tests must meet quality assurance criteria and test conditions specified in the most recent versions ofthe EPA methods listed in Section C.Page 36 of52 PermitNo. WA000088-4

and the Ecology Publication no. WQ-R-95-80, Laboratory Guidance and Whole Effluent Toxicity Test Review Criteria. IfEcology determines any test results to be invalid or anomalous, the Permittee must repeat the testing with freshly collected effluent. 5. The laboratory must use control water and dilution water meeting the requirements ofthe EPA methods listed in Subsection C. or pristine natural water ofsufficient quality for good control performance. 6. The Permittee must conductwhole effluent toxicity tests on an unmodified sample offinal effluent. 7. The Permittee may choose to conduct a full dilution series test during compliance testing in order to determine dose response. In this case, the series musthave a minimum offive effluent concentrations and a control. The series ofconcentrations must include the CCEC and the ACEC. The CCEC and the ACEC may either substitute for the effluent concentrations that are closest to them inthe dilution series orbe extra effluent concentrations. The CCEC equals 0.77% effluent. The ACEC equals 6.7% effluent. 8. All whole effluent toxicity tests that involve hypothesis testing must comply withthe chronic statistical power standard of39% as defined in WAC 173-205-020. Ifthe test does not meetthe power standard, the Permittee must repeat the test on a fresh sample with an increased number ofreplicates to increase the power. 

### 514. Fecal Coliform Study The objective ofthis study is to 1) confirmthe presence, concentration and variability of fecal coliform in the facility's discharge; and iffecal coliform is confirmed in concentrations routinely higher thanthe waste load allocations, 2) to identify control measures suchthe discharge will meet the waste load allocation in the Puyallup River Watershed Fecal Coliform Total Maximum Daily Load (TMDL) Water Quality ImprovementReport and ImplementationPlan ofJune 2011 (publicationNo. 11-10-040). The Studywill be conducted intwo phases. Phase 1 consists oftwo years ofmonitoring the effluent. Phase 2 consists ofpreparation ofan engineering report identifying effluent treatment options, followed by implementation ofthose measures to achieve compliance withthe final permit limits bythe last year ofthe permit cycle.

Phase 1: ByAugust 1, 2013, the permittee shall submit a fecal coliform monitoring planto the Department for review. The monitoring will be designed to determine ifthe source ofthe fecal coliform is internal to the mill and therefore controllable via internal changes or ifthe source is within the facilities waste treatment system (biological/natural) and therefore will require additional controls. The monitoring program will sample the effluent once a week during the critical season as defined in the TMDL. The monitoring plan shall include a Quality Assurance ProjectPage 37 of52 PermitNo. WA000088-4

Plan describing how sampling and analysis will be conducted. Implementation of the monitoring plan will continue through the life ofthe permit. The permittee will begin the monitoring plan during the first dry season ofthe permit. Ifduring the second year ofthe monitoring plan, or any year thereafter, the geometric mean ofthe dry season sampling monitoring result shows the waste load allocation to be exceeded, Phase 2 will be implemented. Phase 2: By January 1, 2015 or in any subsequent year after the critical season monitoring shows the geometric mean ofthe dry season sampling exceeding the waste load allocation, the permittee shall submit an Engineering Report meeting the requirements ofChapter 173-240 to the Department for review. The Engineering Report shall: Summarize the results ofthe fecal coliform bacteriamonitoring inthe discharge determined inPhase 1. Identify and evaluate control measures for fecal coliform inthe discharge. Identify a schedule for implementation ofcontrol measures identified inthe Engineering Report suchthatthe discharge meets the final permit limits by the following years starting at 2018 critical season. The permittee shall begin implementation ofthe control measures identified in the Engineering Report according to the schedule contained therein within 30 days of receipt ofthe Department's writtenresponse. Ifthe Department's response includes comments, those comments must be addressed priorto implementation ofthe control measures identified in the Engineering Report.

Each day upon which a willful violation occurs may be deemed a separate and additional violation. Anypersonwho violates the terms and conditions ofa waste discharge permit may incur, in addition to any other penalty as provided bylaw, a civil penalty inthe amount ofup to ten thousand dollars ($10,000) for every such violation. Each and every such violation is a separate and distinct offense, and in case ofa continuingviolation, every day's continuance is deemed to be a separate and distinct violation. 

### G15. Upset Definition- "Upset" means an exceptional incident in whichthere is unintentional ().nd temporary noncompliance withtechnology-based permit effluent limits because of factors beyond the reasonable control ofthe Permittee. Anupset does not include noncompliance to the extent caused by operational error, improperly designed treatmentPage 43 of52 Permit No. WA000088-4

facilities, inadequate treatment facilities, lack ofpreventive maintenance, or careless or improper operation. An upset constitutes an affirmative defense to an action brought for noncompliance with suchtechnology-based permit effluent limits ifthe requirements ofthe following paragraph are met. A Permittee who wishes to establishthe affirmative defense ofupset must demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: 1. An upset occurred and that the Permittee canidentify the cause(s) ofthe upset. 2. The permitted facility was being properly operated at the time ofthe upset. 3. The Permittee submitted notice ofthe upset as required in Condition S3.E. 4. The Permittee complied with any remedial measures required under S4.C ofthis permit. In any enforcement action the Permittee seeking to establishthe occurrence ofan upset has the burden ofproof. 

### G16. Property Rights This permit does not convey any property rights ofany sort, or any exclusive privilege. 

### G17. Duty to Comply The Permittee must comply with all conditions ofthis permit. Any permit noncompliance constitutes a violation ofthe CleanWater Act and is grounds for enforcement action; for permittermination, revocation and reissuance, or modification; or denial ofa permitrenewal application. 

### G18. Toxic Pollutants The Permittee must comply with effluent standards or prohibitions established under Section 307(a) ofthe Clean Water Act for toxic pollutants within the time provided in the regulations that establishthose standards orprohibitions, even ifthis permit has not yet beenmodifiedto incorporate the requirement. 

### G19. Penalties for Tampering The Clean Water Actprovides that any person who falsifies, tampers with, orknowingly renders inaccurate any monitoring device or methodrequired to be maintained under this permit must, upon conviction, be punished by a fine ofnot more than $10,000 per violation, or by imprisonment for notmore thantwo (2) years perviolation, or by both. Ifa conviction ofa person is for a violation committed after a first conviction ofsuch person under this condition, punishment must be a fine ofnot more than $20,000 per day, ofviolation, or by imprisonment ofnot more than four (4) years, orby both.Page 44 of52 PermitNo. WA000088-4



### G20. Reporting Requirements Applicable to Existing Manufacturing, Commercial, Mining, and Silvicultural Dischargers The Permittee belonging to the categories ofexisting manufacturing, commercial, mining, or silviculture must notify Ecology as soon as they know orhave reason to believe: 1. That any activity has occurred or will occur which would result inthe discharge, on a routine or frequent basis, ofany toxic pollutant which is not limited inthis permit, if that discharge will exceed the highest ofthe following "notification levels:"

a. One hundred micrograms per liter'(100 )lg/L). b. Two hundred micrograms per liter (200 )lg/L) for acrolein and acrylonitrile; five hundred micrograms per liter (500 )lg/L) for 2,4-dinitrophenol and for 2-methyl4,6-dinitrophenol; and one milligramper liter (1 mg/L) for antimony. c.

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, ofa toxic pollutant which is not limited in this permit, ifthat discharge will exceed the highest ofthe following "notificationlevels:"

a. Five hundred micrograms per liter (500)-Lg/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 122.21(g)(7). d. The level established bythe Director in accordance with 40 CFR 122.44(f). 

### G21. Compliance Schedules Reports ofcompliance or noncompliance with, or any progress reports on, interim and final requirements contained in any compliance schedule ofthis permitmust be submitted no later than fourteen (14) days following each schedule date.Page 45 of52 PermitNo. WA000088-4



## APPENDIX A LIST OF POLLUTANTS WITH ANALYTICAL METHODS, DETECTIONLIMITS ANDQUANTITATION LEVELS
The Permittee must use the specified analytical methods, detection limits (DLs) and quantitation levels (QLs) in the following table for permit and applicationrequired monitoring unless:

• The Permittee documents that there is not a W A state accredited commercial laboratory reasonably available that can achieve the specified DLs or QLs.
• Anotherpermit condition specifies other methods, detection levels, or quantitation levels.
• The method used produces measurable results inthe sample and EPAhas listed it as an EPA-approved method in 40 CFRPart 136.
Ifthe Permittee uses an alternative method, not specified in the permit and as allowed above, itmust report the test method, DL, and QL onthe discharge monitoring report or inthe required report.
Whenthe permit requires the Permittee to measure the base neutral compounds in the list ofpriority pollutants, it must measure all ofthe base neutral pollutants listed inthe 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 ofbase neutrals below from Ecology's Persistent Bioaccumulative Toxics (PBT) List. Itonly added those PBT parameters ofinterestto Appendix A that did not increase the overall cost ofanalysis umeasonably. Ecology added this appendix to the permit in order to reduce the number ofanalytical "non-detects"

Detectionlevel (DL) or detection limit means the minimum concentration ofan analyte (substance) that canbe measured and reported with a 99% confidence that the analyte concentration is greater than zero as determined bythe procedure given in40 CFRpart 136, Appendix B.
2. Quantitation Level (QL) also known as MinimumLevel ofQuantitation (ML)- The lowest level at which the entire analytical system must give a recognizable signal and acceptable calibrationpoint for the analyte. Itis equivalent to the concentration ofthe lowest calibration standard, assuming thatthe lab has used all method-specified sample weights, volumes, and cleanup procedures. The QL is calculatedbymultiplying the MDL by 3.18 and rounding the result to the number nearestto (1, 2, or 5) x 10°, where n is an integer. (64 FR 30417). ALSO GIVEN AS: The smallest detectable concentration ofanalyte greaterthanthe Detection Limit (DL) where the accuracy (precision & bias) achieves the objectives ofthe intended purpose.
