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 sum by the total number ofdaily discharges measured. Additional allocation may be permitted for stormwater runoffand ballast water according to Permit Condition Sl.B. The maximum daily effluent limit means the highest allowable daily discharge. The daily discharge means the discharge ofa pollutant measured during a calendar day. Forpollutants with limits expressed in units ofmass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For other units ofmeasurement, the daily discharge is the average measurement ofthe pollutant over the day. Additional allocation may be permitted for st01mwater runoffand ballast water according to Permit Condition Sl.B. Continuous means uninterrupted except for brieflengths oftime for calibration, for power failure, or for necessary equipment repair or maintenance. Withthe exception ofpH, the Permittee must sample every 4 hours when continuous monitoring is not possible. 24-hour composite means a series ofindividual samples collected over a 24-hour period into a single container and analyzed as one sample. Grab means an individual sample collected over a fifteen (15)-minute or less period. The monitoring frequencies for these parameters have beenreduced as a result ofconsistent performance well belowthe permit limits. Shouldthe treatmentperformance deteriorate Ecology may increase the monitoring frequencies to the levels required inthe previous permit (COD 7/7 and Ammonia 5/7). Ecology will notifythe Permittee by letter to increase monitoring upon determination ofdeteriorating performance. Indicates the range ofpermitted values. Any excursions below 5.0 and above 10.0 at any time are violations. The instantaneous maximum and minimumpHmust be reported inthe monthly. Do not average pHvalues. WhenpH is continuously monitored, excursions between 5.0 and 6.0, or 9.0 and 10.0 are not considered violations provided no single excursion exceeds 60 minutes in length and total excursions do not exceed 7 hours and 30 minutes per month. IfpH data from the continuous monitor is unavailable, pHmonitoring must consist ofhourly grab samples. The Permittee must sample the final effluent (Outfall 001) weekly starting Aprill to November 1, 2012 and analyze the sample for fecal coliform. The method used for the analysis must conform to those listed inAppendix B. The results ofthe analysis mustbe reported inthe monthly DMR. · The average daily crude throughput must be reported inthe monthly DMR. The Permittee must sample the final effluent (Outfall 001) annually and analyze the sample for the priority pollutants and other pollutants listed in Appendix B. See Appendix B for required detection (DL) or quantitation (QL) levels. The detection limit and the method must conform to those listed. The Permittee must submit the results ofthese analyses to Ecology within 90 days ofeach sampling event. List the data intabular form withthe method, detection limit, and the measured value including units. The PCBs and pesticides listed inAppendix Bare not required to be tested for unless they are used at the refinery.Page 10 of60 Pem1it No. WA0022900 B. Ballast and Stormwater Allocations (Outfall 001) The Permittee is authorized to discharge additional amounts ofthe following parameters based on stormwater and ballast water flow through Outfall 001. The Pe1mittee must determine ballast water volume by gauging the ballast water storage tanks. Report the cumulative monthly ballast water volume withthe DMRifthe ballast allocation is not used. Ifthe ballast water allocation is used then the Permittee must submit with the DMR a report showing the daily volume ofballast water released to the wastewater system for treatment. The Permittee must determine the storm water flow rate as the difference between total measured effluent through Outfall No. 001 and the sum ofballast water plus the average dry weather flow rate. The average dry weather flow is hereby established as 

### 3.87 MGD. The Permittee may onlyuse the maximum daily storm water allocation onthose storm water flow days whenthe base limits from S 1 above are exceeded. During the summer months ofJune through October the Permittee may only claim the storm water allocation for the maximum daily value when it can demonstrate that measurable rainfall has occurred at the refinery site during the previous 10 calendar days. Ifrainfall data on-site is unavailable due to equipment malfunction, data from nearbyrainfall gauging stations can be used.

Storm water flow is equal to the amount offlow inexcess ofthe established dry weather flowplus ballast water. For the months ofJune through October, qualifying storm water flow days are only those days when measurable rainfall occurred at the refinery site during the previous 10 calendar days. Average Monthly Stormwater Allocation (AMSWA) is defined as the sum ofstorm water flows from qualifying storm water flowPage 11 of60 Pe1mit No. WA0022900 days sampled divided bythe number ofqualifying days times the average monthly allocation for that parameter. The Total Average Monthly Limit (T) is the sum ofthe base average monthly limit (B) (listed in Condition Sl.A.) plus the Average Monthly Stormwater Allocation (listed in ConditionSl.B.) T

a The Permittee maypetition Ecology to reduce or suspend monitoring for one or more ofthese parameters upon consistent attainment ofbenchmark values. Consistent attainment is defined as eight consecutive quarters wherePage 12 of60 Permit No. WA0022900 the reported values are equal to or less than benchmark values.

b Qumiers are defined as: First Quarter- January, February, March Second Quarter- April, May, June Third Quarter- July, August, September Fourth Quarter October, November, December Benchmark values are not water quality standards orpermit limits. They are indicator values. Values at or belowthe benchmark are considered unlikely to cause a water quality violation. Ifthere is no discharge during an entire quarter, the Permittee must submit a discharge monitoring report to Ecology stating that no discharge occurred. The Permittee must sample the stormwater discharges from Outfalls 002, 003, 004, 005, and 007 during the first fall storm event eachyear. "First fall storm event" means the first time after October 1st ofeach year that precipitation occurs and results in a stormwater discharge from a facility. The Permittee must collect smnples within the first 12 hours ofstormwater discharge events. Ifit is not possible to collect a sample within the first 12 hours ofa stormwater discharge event, the Permittee must collectthe smnple as soon as practicable after the first 12 hours, and keep documentation withthe sampling records explaining why they could not collect samples within the first 12 hours. The Permittee is not required to sample outside ofregular environmental staff business hours (Monday-Friday from 8:00am-5:00pm), during unsafe conditions, or during quarters where there is no discharge. For each stormwater sample taken, the Permittee must record the following infom1ation and retain it on-site for Ecology review for each stormwater smnple taken. a. Sample date. b. Sample time. c. A notation describing ifthe Permittee collectedthe sample within the first 12 hours ofstormwater discharge events. d. An explanation ofwhy it could not collect a sample within the first 12 hours ofa stormwater discharge event, ifit was not possible. e. Sample location (using SWPPP identifying number). f. Method ofsampling, and method ofsmnple preservation, if applicable. g. Individual who performedthe sampling. Ifno stormwater smnple was sampled from the site during a givenreporting period, the Permittee must submitthe report indicating "no sample sampled", or "no discharge during the quarter", as applicable.Page 13 of60 Permit No. WA0022900

The Pe1mittee must conduct and document visual inspections ofOutfalls 002, 003, 004, 005, and 007 each month. The inspections must be conducted by qualified personnel. Each inspection must include visual observations made at the stmmwater sampling locations and areas where the stormwater is discharged off-site. The inspection must include observations for the presence of:floating materials, visible sheen, discoloration, turbidity, odor, or presence ofillicit discharges. The inspection must include an assessment that all BMPs have been implemented, the effectiveness of the BMPs, and whether any maintenance or changes in BMPs are needed. Ifan illicit discharge is discovered, the Permittee must notify Ecology within 7 days. The Permittee must eliminate the illicit discharge within 30 days. The Permittee mustrecord the results ofeach inspection including:

a. Time and date ofthe inspection b. Locations inspected. c. Any observations ofnon-compliance and the remedial actions the Permittee plans to take to resolve the non-compliance. d. Name, title, and signature ofthe person conducting the inspection. The Permittee must submitthe results ofquarterly stormwater monitoring and monthly inspections to Ecology bythe due dates below:

Response to Monitoring Results Above BenchmarkValues Each time that sampling results are above a benchmark value or outside the benchmarkrange for pH, the Permittee must take the following actions:

a. Conduct an inspection ofthe drainage area for the affected outfall as promptly as possible butno later than two weeks after receipt ofsamplingresults. b. Identify the possible sources ofstormwater contamination from industrial activity that are causing or contributing to the elevated levels ofthe benchmark parameter.

c. Evaluate whether any improvements or changes to existing bestmanagement practices (BMPs) or additional operational source control, structural sourcePage 14of60 PennitNo. WA0022900 control, or treatment BMPs are warranted to reduce stormwater contamination below benchmark values. Any elevated benchmark parameter levels demonstrated to be attributable to vegetative or naturally-occurring conditions do not require additional BMPs. d. Implement changes to existing BMPs or additional BMPs as identified as needed in the investigation on a schedule approved by Ecology. Ecology may waive the requirement for additional controls and/or BMPs based on a technical demonstration by the Permittee that implementation ofadditional controls is not feasible or not necessary to prevent discharges that may cause or contribute to a violation ofwater quality standard.

e. Include a briefsummary ofinspection results and remedial actions taken with the monitoring report for the time period in which sample results were above benchmark values. D. Firewater Testing The Permittee is authorized to discharge treated effluent viathe dockside firewater system during monthly testing ofthe fire suppression system and Emergency Response Team (ERT) training. The Permittee is required to meet the discharge requirements for Outfall 001 as listed above. The Permittee must not use foam during firewater testing or during the ERT training. The Permittee must report firewater testing for the above events in the monthly discharge monitoring report and must report duration and an estimated flow volume. E. Alternative Stormwater Discharge The Permittee is authorized to discharge water from the Stormwater Holding Pondvia Outfall 003 only during a rainfall event whenthere is a risk ofoverflowing the Final Holding Pond which contains treated process water. The Permittee is authorized to discharge stormwater at Outfall 006 to the Strait ofGeorgia during a rainfall event when there is a risk ofoverflowingthe dock on-shore sump. During each event ofa discharge described inthis subsection, the Permittee must record the. estimated flow and collect daily grab samples at the location ofthe alternative stormwater discharge for turbidity, TSS, O&G, and pH analysis. The Permittee must notify Ecology ofany stormwater discharges under this subsection within 24 hours ofsuch an event and submitthe results ofmonitoring in the monthly discharge monitoringreport. F.

S2. MONITORING REQUIREMENTS A. Monitoring Schedule The Permittee must monitor in accordance with the schedules specified for the final effluent and stormwater discharges inPermit Condition S1 and the requirements specified in Appendix B.Page 17 of60 PermitNo. WA0022900 B. Sampling and Analytical Procedures Samples and measurements taken to meet the requirements oftllis permit must represent the volume and nature ofthe monitored parameters, including representative sampling ofany unusual discharge or discharge condition, including bypasses, upsets, and maintenance-related conditions affecting effluent quality. After a portion ofthe daily sample is removed for the Permittee's analysis, the remainder, 2-3 gallons (minimum) mustbe retained until3:00 pm ofthe following day. The composite sample must be kept refrigerated at or below 6 °C inthe dark during collection and storage. On days when the discharge occurs over a period of time too short to collect sufficient sample for testing and retainage, hourly grab samples canbe used to provide sufficient volume for testing and retainage. Sampling and analytical methods used to meet the monitoring requirements specified in this permit must conform to the latest revision ofthe Guidelines Establishing TestProcedures for the Analysis of Pollutants contained in 40 CFR Part 136. C. FlowMeasurement, Field Measurement, and Continuous Monitoring Devices The Permittee must:

G. Maintaining a Copy ofThis Permit The Permittee must keep a copy ofthis permit at the facility and make it available uponrequest to Ecology inspectors. ·Page 23 of60 Pe1mit No. WA0022900

S4. OPERATIONAND MAINTENANCE The Permittee must, at all times, properly operate and maintain all industrial wastewater and stormwater facilities or systems oftreatment and control (and related appurtenances) which are installed to achieve compliance with the terms and conditions ofthis permit. Proper operation and maintenance includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation ofback-up or auxiliary facilities or similar systems, which are installedby a Permittee whenthe operation is necessary to achieve compliance with the conditions ofthis permit. A. Operations and Maintenance Manual The Permittee must:

1. Maintain and follow the Operations and Maintenance (O&M) Manual for the wastewater treatment plant. 2. Review and update the O&M Manual when changes occur at the refinery that significantly affect the volume or character ofthe wastewaterprocessed by the wastewater treatment plant. 3.

Emergency procedures for plant shutdown and cleanup in event ofwastewater system upset or failure. 2. Procedures to maintaintreatment efficiency during scheduled maintenance operations at the wastewater treatment plant. Forthe purposes ofthis NPDES permit, a Treatment System Operating Plan (TSOP) is a concise summary ofspecifically defined elements ofthe O&MManual. The TSOP must not conflict withthe O&MManual and must include the following information: 1. A baseline operating condition, which describes the operatingparameters and procedures, used to meet the effluent limits in Condition S1 at the production levels used in developing these limits. 2. The planmust describe the operating procedures and conditions needed to maintain treatment efficiency at less than design loading conditions

.. 3. Inthe event ofan upset, due to plantmaintenance activities, severe stormwater events, start ups or shut downs, or other causes, the planmust describe the operatingprocedures and conditions employedto mitigate the upset. 4. A description ofany regularly scheduledmaintenance or repair activities at the facility which would significantly affect the volume or character ofthe wastes discharged to the wastewater treatment system and a plan for treating/controlling the discharge ofmaintenance-related materials (such asPage 24 of60 Pe1mit No. WA0022900 cleaners, degreasers, solvents, etc.). The Permittee must submit an updated Treatment System Operating Plan to Ecology by 

### September 1, 2016. This plan must be updated and submitted to Ecology, as necessary during the permitterm, to include requirements for any major modifications to the wastewater treatment system. B. Bypass Procedures This permitprohibits a bypass which is the intentional diversion ofwaste streams from any portion ofa treatment facility. Ecology maytake enforcement action against a Permittee for a bypass unless one ofthe following circumstances (1, 2, or 3) applies. 1. Bypass for Essential Maintenance withoutthe Potential to Cause Violation of Permit Limits or Conditions. Bypass is authorized ifit is for essential maintenance and does nothave the potential to cause violations oflimitations or other conditions ofthis permit, or adversely impactpublic health as determined by Ecologypriorto the bypass. The Permittee must submitpriornotice, ifpossible, at least ten (10) days before the date ofthe bypass. Notice is not required where redundant equipment is available to perform the functions ofequipment scheduled for bypass during maintenance. 2. Bypass whichis Unavoidable, Unanticipated, and Results inNoncompliance of this Permit. This bypass is permitted only if:

a. Bypass is unavoidable to prevent loss oflife, personal injury, or severe property damage. "Severeproperty damage" means substantialphysical damage to property, damage to the treatment facilities which would cause themto become inoperable, or substantial and permanent loss ofnatural resources which canreasonably be expectedto occur inthe absence ofa bypass. b. No feasible alternatives to the bypass exist, such as:

• The use ofauxiliary treatment facilities. • Retention ofuntreated wastes. • Stoppingproduction. • Maintenance during normal periods ofequipment downtime, but not ifthe Permittee ·should have installed adequate backup equipment in the exercise ofreasonable engineeringjudgmentto prevent a bypass.Page 25 of60 Permit No. WA0022900

• Transport ofuntreated wastes to another treatment facility or preventative maintenance), or transpmi ofuntreated wastes to another treatment facility.

c. Ecology is properly notified ofthe bypass as required in condition S3E of this permit. 3. Ifbypass is anticipated and has the potential to result innoncompliance 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 orplannedto reduce, eliminate, and prevent reoccurrence ofthe bypass. b. For probable constructionbypasses, the Permittee must notifY Ecology of the need to bypass as early in the 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 extent practical. 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 considerthe following priorto issuing an administrative order for this type ofbypass:

• Ifthe bypass is necessary to perform construction or maintenance-related activities essential to meet the requirements ofthis permit. • Iffeasible alternatives to bypass exist, such as the use ofauxiliary treatment facilities, retention ofuntreated wastes, stopping production, maintenance during normal periods ofequipment down time, ortransport ofuntreated wastes to another treatment facility.Page 26 of60 PermitNo. WA0022900

• 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 onbypass incidents ofsignificant duration, to the extent feasible. Ecology will approve a request to bypass by issuing an administrative order under RCW 90.48.120. C. Duty to Mitigate The Permittee is required to take all reasonable steps to minimize orprevent any discharge or sludge use or disposal in violation ofthis permitthathas a reasonable likelihood ofadversely affecting humanhealth orthe environment. SS. FACILITY LOADING A. Design Criteria The flows orwaste loads for the permitted facility must not exceed the following design criteria: Parameter Design Quantity Daily Maximum Flowfrom the Secondary Clarifier 13MGD Daily Maximum BOD5 Influent Loading to Aeration Tank 25,160 lbs/day B. Plans for Maintaining Adequate Capacity The Permittee must submitto Ecology a plan and a schedule for continuingto maintain capacity when: 1. The actual flow or waste load reaches 85 percent ofany one ofthe design criteria in S5.A for three consecutive months; or 2. Theprojected increase wouldreach design capacity within five years, whichever occurs first. Ifsucha plan is required, it must containprovisions and a schedule for continuing to maintain capacity. The capacity as outlined inthis planmustbe sufficientto achieve the effluent limitations and other conditions ofthis permit. The planmust address the following actions and any others necessary to meetthe objective ofmaintaining capacity. 1. Analysis ofthe present design including the introduction ofanyprocess modifications that would affect the ability ofthe existing facility to achieve effluent limits and otherrequirements ofthis permit at levels in excess ofthe existing design criteria specified inparagraphA, above.Page 27 of60 Permit No. WA0022900

2. Reduction or elimination ofexcessive infiltration and inflow into the sewer system. 3. Limitation on future additional waste loads. 4. Modification or expansion offacilities necessary to accommodate increased flow or waste load. Engineering documents associated with the plan must meet the requirements of WAC 173-240-060, "Engineering Report," and be approved by Ecology prior to any construction. 

### S6. NON-ROUTINE AND UNANTICIPATED DISCHARGES A. Beginning onthe effective date ofthis permit, the Permittee may discharge nonroutine wastewater or clean water such as storage tank hydro test water or fire system test water from Outfalls 002, 003, and 007 on a case-by-case basis if approved byEcology. Priorto any such discharge, the Permittee must contact Ecology and at a minimum provide the following information: 1. The proposed discharge location. 2. The nature ofthe activity that will generate the discharge. 3. Any alternatives to the discharge, such as reuse, storage, or recycling ofthe water. 4. The total volume ofwater it expects to discharge. 5. The results ofthe chemical analysis ofthe water. The Permittee must analyze the water for all constituents normally monitored for the discharge. The analysis must also include hardness, any metals that are limited by water quality standards, and any other parameter deemed necessary byEcology. All discharges must comply with the effluent limits as established in Condition S1. ofthis permit, water quality standards, and any other limits imposed by Ecology. 6. The date ofproposed discharge. 7. The expectedrate ofdischarge discharged, in gallons perminute. The Permittee must limitthe discharge rate so it will not cause erosion ofditches or structural damage to culverts and their entrances or exits. B. The discharge cannot proceeduntil Ecology has reviewed the informationprovided and has authorized the discharge by email/letterto the Permittee or by an Administrative Order.Page 28 of60 PermitNo. WA0022900



### S7. ACUTE TOXICITY A. Effluent Limit for Acute Toxicity 

### The effluent limit for acute toxicity is: No acute toxicity detected in a test concentration representingthe acute critical effluent concentration (ACEC). The ACEC means the maximum concentration ofeffluent during critical conditions at the boundary ofthe acute mixing zone, defined in Section S1.F ofthis permit. The ACEC equals 3.6% effluent. B. Compliance Withthe Effluent Limit for Acute Toxicity Compliance withthe effluent limit for acute toxicity means the results ofthe testing specified in subsection C. show no statistically significant difference in survival betweenthe control and the ACEC. Ifthe testresults show a statistically significant difference in survival betweenthe control and the ACEC, the test does not comply withthe effluent limit for acute toxicity. The Permittee must then immediately conduct the additional testing described in subsection D. The Permittee will comply withthe requirements ofthis section by meeting the requirements ofsubsection D. 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 in survival betweenthe control and the ACEC is less than 10%, the Permittee must conductthe hypothesis test at the 0.01 level ofsignificance. C. Compliance Testing for Acute Toxicity The Permittee must: 1. Begin compliance testing by 

### May 1, 2012. Performthe acute toxicity tests with 100% effluent, the ACEC, and a control, or with a 

### full dilution series. 2. Submit a written report ofall test results to Ecology within sixty (60) days after completion ofthe test. The Permittee mustperform compliance tests 

### quarterlyusing each ofthe species and protocols listed below on a rotating basis:

······ D. Response to Noncompliance with the Effluent Limit for Acute Toxicity Ifa toxicity test conducted under subsection C. determines a statistically significant difference inresponse betweenthe ACEC and the control, using the statistical test described in subsection B., the Permittee mustbegin additional testing within one week from the time ofreceiving the testresults. The Permittee must: 1. Conduct one additional test each week for four consecutive weeks, using the same test and species as the failed compliance test. 2. Test at least five effluent concentrations and a control to determine appropriate point estimates. One ofthese effluent concentrations must equal the ACEC. The results ofthe test atthe ACEC will determine compliance withthe effluent limit for acute toxicity as described in SubsectionB. 3. Returnto the original monitoring frequency in Subsection C. after completion ofthe additional compliance monitoring. Anomalous test results: Ifa toxicitytest conductedunder subsection C. indicates noncompliance with the acute toxicity limit andthe Permittee believes that the test result is anomalous, the Permittee may notify Ecology that they believe the compliance testresult is anomalous. The Permittee should conduct one additional test then wait for notification from Ecology before completingthe additional testing required above. The Permittee must submitthe notification withthe report ofthe compliance testresult and identify the reason for consideringthe compliance testresult to be anomalous. IfEcology determines thatthe testresult was not anomalous, the Permittee must complete all ofthe additional monitoring required in this subsection. Or, Ifthe one additional test fails to comply withthe effluent limit for acute toxicity, thenthe Permittee must complete all ofthe additional monitoring required inthis subsection. Or, IfEcology determines that the test result was anomalous, the one additional test result will replace the anomalous testresult. Ifall ofthe additional testing complies with the permit limit, the Permittee must submit a report to Ecology onpossible causes and preventive measures for the transient toxicity event, whichtriggered the additional compliance monitoring. This report must be based upon a review ofall pertinent and recent facility records, including:Page 30 of60 PetmitNo. WA0022900 1. Operating records 2. Monitoring results 3. Inspection records 4. Spill repmis 5. Weather records 6. Production records 7. Raw material purchases 8. Pretreatmentrecords, etc. Ifany toxicity test conducted under subsection D. 1. shows a statistically significant difference in response between the ACEC and the control, using the statistical test described in subsection B, thenthe test result is a violation ofthe acute limit. E. Sampling and Reporting Requirements 1. The Permittee must submit all reports for toxicity testing in accordance with the most recent version ofDepartment ofEcology PublicationNo. WQ-R-95-80, Laboratory Guidance and Whole Effluent Toxicity Test Review Criteria.

The laboratory must use whichever one ofthe two species that will give a valid result in each particular test. Anomalous test results: Ifthe Petmittee believes that a chronic toxicity test conducted under this section is anomalous, the Permittee may notify Ecology that they believe the test result is anomalous. The Permittee must submit the anomalous notification with the report ofthe test result and identifY the reason for considering the compliance testresult to be anomalous. The Permittee should conduct one additional test and submit that result as well to Ecology. IfEcology determines that the test result was not anomalous, the test result will be used for characterizingthe effluent and for making future chronic toxicity limit determinations. IfEcology determines that the test result was anomalous, the one additional test result will replace the anomalous testresult. B. Sampling and Reporting Requirements 1. The Permittee must submit all reports for toxicity testing in accordance with the most recent version ofEcology PublicationNo. WQ-R-95-80, Laboratory Guidance and Whole Effluent Toxicity TestReview Criteria.

The Permittee may choose to conduct a full dilution series test during characterization in order to determine dose response. In this case, the series must have a minimum offive effluent concentrations and a control. The series of concentrations must include the Chronic Critical Effluent Concentration (CCEC) and the ACEC. The CCEC and the ACEC may either substitute for the effluent concentrations that are closest to them in the dilution series or be extra effluent concentrations. The CCEC means the maximum concentration ofeffluent during critical conditions at the boundary ofthe mixing zone, defined in Section S1.F. of this permit. The CCEC equals 0.8% effluent. The ACEC equals 3.6% effluent. 8. All whole effluent toxicity tests that involve hypothesis testing must comply with the chronic statistical power standard of39% as defined in WAC 173-205-020.

The Permittee mustrecharacterize sediment toxicity at theNorthPier ifEcology determines that significant spills or accumulation ofspills have occurred since the 2006 baseline sediment characterization. A decision will be made by Ecology as to whether a reported spill or accumulation ofspills is significant enough to warrant additional sediment sampling at the NorthPier. The purpose ofthe plan is to recharacterize sediment toxicity in the Permittee's discharge location betweenAugust 15th and September 15th.Page 34 of60 PennitNo. WA0022900 The Permittee must prepare a Sediment Sampling and Analysis Plan following the guidance provided in the Sediment Source Control Standards User Manual, Appendix B: Sediment Sampling and Analysis Plan (Ecology, 2008) and cunentPuget Sound Estuary Program Protocols. A. The Permittee must submit the Sediment Sampling and Analysis Plan (SAP) to Ecology by February 1, 2015. The SAP must include Microtox as the chronic effects bioassay test for this sampling event. B. The Permittee mustperform sediment sampling during the first stable period (midAugust through mid-September) following Ecology's approval ofthe plan. C. The Permittee must submit a Sediment DataReport containing the results ofthe sediment sampling and analysis no later than 180 days after completion ofsampling. The Sediment DataReport must also include electronic copies ofthe sediment chemical and/or biological data formatted according to Ecology's Environmental Information Management (EIM) System templates. 

### Sll. POLLUTION PREVENTION Pollutionpreventionplanning and activities at the facility include the:

• Newpollutionpreventionprojects identified for the upcoming permit cycle in the plan update.

• Standard Operating Procedures (SOPs), Best Management Practices (BMPs), and workpractices developed and updated from previous permitpollution plans, stormwaterpollutionprevention plans (SWPPPs), solid waste control plans, and spill plans. The Permittee must continue to ensure proper operation and maintenance ofthe refinery process units and wastewater treatment system by following existing SOPs, BMPs, and workpractices. The Permittee must continue or maintain these procedures and other measures and/or facilities cunently employed at the refinery to prevent orminimize the potential for release ofpollutants to the wastewater treatment system, stormwater, and/or waters ofthe state unless modified by the pollutionpreventionplan update required below. Storm water Stormwater BMPs must:

• Provide all known, available, and reasonable methods ofprevention, control, andtreatment (AKART) ofstormwaterpollution.

• Ensure the discharge does not cause or contribute to a violation ofthe Water Quality Standards.Page 35 of60 Permit No. WA0022900

• Comply with applicable federal technology-based treatment requirements under 40 CFR 125.3.

Solid Waste Be consistent with the Stormwater Management Manual for Western Washington (2005 edition) or provide an equivalent level ofpollution prevention approved by Ecology.

The Permittee must handle and dispose ofall solid waste material in such a manner as to prevent its entry into state ground or surface water. The Permittee must not allow leachate from its solid waste material to enter state waters without providing all known, available and reasonable methods oftreatment, nor allow such leachate to cause violations ofthe State Surface Water Quality Standards, Chapter 173-201A WAC, or the State Ground Water Quality Standards, Chapter 173-200 WAC. The Permittee must apply for a permit orpermit modification as may be required for such discharges to state ground or surface waters. Storage TankWastewater The Permittee must remove wastewater from oil, product, and intermediate distillate storage tanks in a manner and with facilities as required to prevent the wastewater from draining or spilling onto the ground. A. PollutionPreventionPlanUpdate and Implementation The Permittee must update its Pollution Prevention Plan and submit itto Ecology for review and approval by September 1, 2013. The Permittee must implement the approved pollutionpreventionplan update and any approved modifications to the plan and abide by the timefrarnes identified throughout the tetm ofthe permit. The objective ofthis update is to identifY any new sources ofpollutants, to reevaluate previously identifiedpollutionpreventionopportunities and to identifY any new opportunities and implement those that are technically and economically achievable. Previously identified opportunities include those identified by the facility intheir currentPollution Prevention plan and those identified inEcology Publication 02-07-017 (Water PollutionPrevention Oppmiunities inPetroleum Refineries). The update must also include an evaluation ofthe existing SOPs, BMPs, and workpractices developed underprevious pollutionprevention planning/activities. Specifically, the Permittee should evaluate the following pollutionprevention opportunities: 1) lining the wastewater and stormwater treatment ponds, 2) increasing the removal efficiency ofTSS inthe wastewater and stormwater treatment trains, and 3) evaluating the potential to remove mercury, copper, and dioxin from the process wastewater.Page 36 of60 Permit No. WA0022900 B. Specific Plan Update Requirements The Permittee must update the following plan elements as necessary to address changes: the policy statement and signature, employee involvement, training and awareness, descriptions ofcurrent pollution prevention activities, and the description ofpotential pollutants and sources. Appendix C includes references to guidance documents, specific items to be included in the plan, and procedures for identifYing, evaluating and prioritizing pollutionprevention opportunities. Other information available to the Permittee may also be used inpreparing the plan. The updated plan must include a schedule for implementation ofeachnewly selected opportunity. Ifa detailed analysis oftechnical and economical feasibility for any pollution prevention opportunity will extend beyondthe deadline for submitting the updatedplan, the Permittee must include a schedule for completing the analysis in the plan submittal. The timeframe for implementing any opportunities scheduled for further evaluation and then selected must be provided in the biennial report. The Permittee must modifY the plan ifthe Permittee or Ecology determine during inspections or investigations, that existing BMPs are, or would be, ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The Permittee must modifythe plan as necessary to include additional or modified BMPs designed to correctproblems identified. The Permittee must modifY the planwhenever there is a change in design, construction, operation, or maintenance at the facility that significantly changes the nature ofpollutants in wastewater or stormwater from the facility, significantly increases the quantity ofpollutants discharged, or causes the pollutionprevention plan and existing SOPs, BMPs, or work practices to be less effective in controlling pollutants. The Permittee mustprovide for implementation ofany modifications to the pollutionpreventionplan in a timely manner. The Permittee mustperiodically evaluate and modifY, as necessary, the pollution preventionplan and existing SOPs, BMPs, and work practices to ensure that ithas been updated or otherwise modified to reflect current conditions, that measures to reduce or eliminate pollutant loadings selected inthe plan are adequate and are being properly implemented in accordance with the terms ofthe permit, and whether any additional controls are needed. C. Stormwater Inspections The Permittee must conduct two stormwater inspections peryear; one during the wet season (October 1 - April 30) and the other during the dry season (May 1 - September30). The Permittee must conductthe wet season inspection during a rainfall event and must include observations ofthe presence ofany floating materials, suspendedPage 37 of60 PermitNo. WA0022900 solids, oil and grease, discolorations, turbidity, odor, etc. in stormwater runoff throughout the refinery that could contribute to a discharge off-site. The dry season inspection must determine the presence ofunpennitted nonstormwater discharges such as sanitary wastewater, non-contact cooling water, process wastewater, and drainage from rawmaterial/product/waste storage to the stormwater drainage system. Ifan unpermitted, non-stmmwater discharge is discovered, the Petmittee must immediately notify Ecology. Inspections must be conducted bypersonnel who are knowledgeable and trained in the application ofBMPs and pollutionprevention activities at the refinery. Results from the stormwater visual inspections must be reported inthe pollutionprevention plan biennial update reports. D. Biennial Reporting The Permittee must submit a biennial progress report by September 1st (within 2 years after submittal ofthe updated Pollution Prevention Planrequired in Condition Sl2.A.) and every two years thereafter. The report must identify the implementation status of eachpollutionprevention opportunity selected, the benefits or other results of implementation actions completed, and any modifications orupdates to the plan. The reportmust also include a summary ofthe results ofstorm water inspections. E. Continuous Improvement Inmaintaining, implementing, and updating the pollutionpreventionplan, the Permittee should employ continuous improvementprinciples, including the systematic and ongoing identification, evaluation, and implementation ofpollution prevention opportunities in all decisions having environmental consequences.

### APPENDIX A- CALCULATING STORMW ATERAND BALLAST WATERALLOCATIONS CALCULATING STORMWATERAND BALLAST WATERALLOCATIONS Sl.A effluent limitations in the BP NPDES permit are base permit limits that apply to process water flow- these values are fixed. Sl.C. effluent limitations in the BP NPDES permits are used to calculate incremental limits that apply to storm water and ballast water- the Sl.C. limitations are actually multipliers. The incremental limit calculated using one ofthe multipliers is added to the base pennit limit for commingled discharges. Storm water flow is calculated bythe subtraction ofan estimated dry weather flow and ballast water flow from the total flow discharged each day. Ballastwater flow is measured by gauging the tanks at the refinery dock. The ballast and storm water allocations in the BP NPDES permit are based on guidelines in 40 CPR419.12(c) and 419.22(e). The allocations for storm water are intended to apply to runofffrom areas associated with industrial activity, not outlying areas such as parking lots and surrounding acreage. Daily maximum storm water and ballast water allocations must only be used on an individual parameter basis when mass loading in the effluent exceeds daily maximum base permitlimitations and when measurable rainfall has occuned within the timeframes established in the NPDES permit. The BP NPDES permit states that during specified summer months, the permittee will only be allowed to claim the storm water allocation when it can be demonstrated thatmeasurable rainfall has occurred at the refinery site during the previous 10 calendar days. In calculating storm water allocations, look at the days where total effluent flow exceeds the established dry weather flow. The difference is flow due to storm water. Ifthe storm water allocation can be claimed perthe conditions ofthe previous paragraph, multiply the additional flow (in million gallons per day, MGD) by the appropriate allocation provided in the NPDES permit. This is an incremental permit limit in lbs per day. Evaluating compliance withthe maximum daily permit limitation- on a day by day basis comparethe maximum discharge for a parameterto the base permit limitationplus the storm water allocation and/or ballast water allocation calculated for thatparameter. Example Calculation 1. Dryweather flow: 1MGD Date: March 15, 1997 Parameter: Oil and Grease (O&G) O&G maximum daily base permit limitation: 100 lbs/day Maximum daily 0& G discharge: 177 lbs/day Total effluent flow: 2.2 MGD Flow rate due to rainfall: 2.2- 1= 1.2 MGD O&G maximum daily storm water allocation: 130 lbs/million gallons O&G incremental limit due to storm water: 1.2 x 130 

### = 156lbs/day O&G maximum daily permit limitation for 3/15/97: 100 

### + 156 = 256lbs/dayPage 49 of60 Permit No. WA0022900
Note: Since 177 is less than 256, the permittee is in compliance with the oil and grease maximum daily permit limitation on the day evaluated. Ifballast water had also been a factor on 3/15/97, an additional oil and grease allocation due to ballast water could have been calculated and added into the maximum daily permit limitation. Evaluating compliance with the monthly average permit limitation

- determine the days where effluent flow exceeds dry weather flow and sampling occurred. Add up the excess flow for these days and divide the result by this number ofdays. Multiply by the monthly average storm water allocation. --this is the incremental storm water allocation. Compare the monthly average discharge for a parameter (total mass loading for the month divided by the days in the month) to the base permit limitation plus the storm water allocation and/or ballast water allocation calculated for that parameter. Example Calculation 2. Dry weather flow: 1MGD Month: November 1997 Parameter: Total Suspended Solids (TSS) TSS average monthly base permit limitation: 120 lbs/day Average monthly TSS discharge: 216lbs/day During the 5 sampling days the total storm waterflow excess was: 2.5 million gallons TSS average monthly storm water allocation: 180 lbs/million gallons TSS incremental limit due to storm water: 2.5/ 5 x 180 

### =90 lbs/day TSS average monthly permit limitation for November 1997: 120 

### +90 

### =210 lbs/day Note: Since 216 is greaterthan 210, the TSS average monthly permit limit is exceeded. Ifballast water had also been a factor in Example Calculation 2, the average monthly permit limit would not have been exceeded. Ballastwater flow for November 1997 (1 day): 50,000 gallons or 0.05 million gallons TSS average monthly ballast water allocation: 170 lbs/million gallons TSS incremental limit due to ballast water: 0.05/ 1 x 170 = 8.5 lbs/day TSS average monthly permit limitation for November 1997: 120 

### +90 

### + 8.5 = 218.5 lbs/dayPage 50 of60 PermitNo. WA0022900 

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

• Another permit condition specifies other methods. • The method used produces measurable results in the 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, it must report the test method, DL, and QL onthe discharge monitoring report orinthe required repmi. Whenthe permitrequires the Permittee to measure the base neutral compounds inthe list of prioritypollutants, it must measure all ofthe base neutral pollutants listed inthe table below. The list includes EPArequired base neutral priority pollutants and several additional polynuclear aromatic hydrocarbons (PAHs). The Water Quality Program added several PAHs to the list of base neutrals belowfrom Ecology's Persistent Bioaccumulative Toxics (PBT) List. Itonly added those PBTparameters ofinterest to Appendix A that did not increase the overall cost of analysis unreasonably. Ecology added this appendix to the permit in order to reduce the number ofanalytical "nondetects" inpermit-required monitoring andto measure effluent concentrations near or below criteria values where possible at a reasonable cost.

Detection level (DL) or detection limit means the minimum concentration ofan analyte (substance) that can be measured and reported with a 99% confidence that the analyte concentration is greater than zero as dete1mined bythe procedure given in40 CFRpart 136, Appendix B. 2. Quantitation Level (QL) also known as Minimum Level ofQuantitation (ML)- The lowest level at whichthe entire analytical system must give a recognizable signal and acceptable calibrationpoint for the analyte. Itis equivalent to the concentration ofthe lowest calibration standard, assuming that the lab has used all method-specified sample weights, volumes, and cleanup procedures. The QL is calculatedby multiplying the MDL by 3.18 and rounding the result to the number nearest to (1,2,or 5) x lOn, where n is an integer. (64 FR 30417). ALSO GIVEN AS: The smallest detectable concentration ofanalyte greater than the Detection Limit (DL) where the accuracy (precision & bias) achieves the objectives ofthe intendedpurpose.

### APPENDIX C- 

### REFINERY NPDES POLLUTIONPREVENTION PLANS- SPECIFIC REQUIREMENTS GUIDANCE DOCUMENTS Guidance available to develop a pollution prevention plan include the GuidanceManual for Preparing/Updatinga Stormwater Pollution Prevention Plan for Industrial Facilities, Apri12004 (Ecology PublicationNo. 04-10-030), the 2005 Storm waterManagementManual for Western Washington Apri12005 (EcologyPublicationNo. 05-10-029), the 'Pollution Prevention and Best Management Practices' section ofthe Water Quality Program Permit Writer's Manual-Chapter XII, revised November 2010 (Ecology Publication No. 92-109),An Organizational Guide to Pollution Prevention,July 2001 (EPA-625-R-01-003), the methodologies ofpollution prevention planning references available at http://www.ecy.wa.gov/programs/hwtr/p2/p3.html, and other information provided bythe Ecology PermitManager. The Permittee is expected to apply the methodologies from the existing guidance to cover other sources, pathways, or measures not covered within the strict scope ofthe WAC 173-307 guidance. PLAN & PLANIMPLEMENTATION REQU1REMENTS Policy Statement and Signature: The pollution prevention plan must include a policy statement articulating management and corporate support for the plan and a commitmentto implementthe plan andto continued pursuit ofpollution prevention opportunities. The plan, plan updates, and modifications must be signed in accordance with Permit Condition G1. Employee Involvement, Training, and Awareness: The pollution prevention plan must include a description ofpersonnel training and employee involvement programs that emphasize pollution prevention and solicit employee ideas about pollution prevention opportunities and other environmental issues. Stafftraining records must be maintained onsite and be available for inspection. Description ofCurrentPollution Prevention Activities: StormwaterPollution Prevention The pollutionprevention plan must include stormwaterpollution prevention requirements consistent with the requirements for a Stormwater Pollution PreventionPlan (Condition S3.) in Ecology's Industrial Stormwater General Permit, effective January 1, 2010. The plan must include a description ofpreventive measures and facilities already employed at the refinery to prevent, reduce, eliminate, or control releases ofpollutants to influent wastewater streams, storm water, and/or waters ofthe state. Incorporating OtherPollution Prevention Plans The Permittee may incorporate applicable portions ofplans prepared for other purposes. Plans or portions ofplans incorporated into the pollution prevention plan become enforceable requirements ofthis permit.Page 59 of60 Pem1itNo. WA0022900 Description ofPotentialPollutants and Sources: The pollution prevention plan must include a detailed description ofthe processes or activities that contribute or potentially contribute pollutants to the treatment plant influent, storm water, groundwater, and wetlands. fnfluent wastewater streams must include those having daily average flow rates equal to or greater than 30 gpm at the point where the wastewater stream enters the collection system and the catalytic wash water spent caustic and wash water waste streams. Minor incidental waste streams to, storm water, such as landscaping fertilizers, do not have to be included. The plan must identify the materials used, processed, stored, treated, or disposed ofat the facility and the pollutants that are generated or potentially generated or released. The level ofdetail provided in the plan should be sufficient to help identify and understand how and why materials are used and pollutants generated or released. Process flow diagrams and/or material input/output information mustbe included on a process unit basis. The Permittee must include in the plan all materials which may become pollutants or cause pollution upon reaching state waters, including, but not limited to: 1) persistent bioaccumulative and toxic chemicals (PBTs), 2) oil and petroleum products and, 3) materials which, when spilled or othetwise released into the environment, would be designated Dangerous Waste (DW) orExtremely Hazardous Waste (EHW) by the procedures set forth in WAC 173-303-070. In determining which sources and pollutants to address in the plan, the Permitteemust use available sampling data, as well as knowledge ofprocesses and materials, and available information onthe relative toxicity or hazard ofmaterials. Sources ofPBTs must be included in the analysis. The Permittee must not be required to sample each stream analytically and may use engineeringjudgmentto assess and quantify material inputs and outputs on a process unit basis. Identification & PreliminaryEvaluation ofPollution Prevention Opportunities: The plan must identify pollution prevention opportunities and provide a detailed analysis ofeach opportunity's technical (including safety considerations) and economic feasibility. Opportunities determined to betechnically and economically feasible will be considered as known, available, and reasonable and therefore are required to be selected and scheduled for implementation. For each pollution prevention opportunity selected, the plan must identify the process(es) or activities it affects, an estimate ofthe amount ofpollutants reduced, and the environmental or other benefits that will be achieved. The Permittee must concentrate on opportunities thatreduce oreliminate PBTs, priority pollutantmetals, diethanolamine (DEA), and methyldiethanolamine (MDEA) to influent and upstream flows to the oily water sewer. Solids and hydrocarbon loadings to the oily water sewer must also be evaluated. Storm water must be evaluated for oil and grease and solids loading as well as toxics. In identifying and evaluating pollution prevention opportunities, the Permittee must considerthe following:

• All reasonably expected activities and conditions, such as normal operations, maintenance, and other ancillary activities; equipment failure; improper operation; upsets, accidents, spills, leaks; and natural events such as rainfall, snowfall, etc. • All areas ofthe refinery with potential to generate water polltJtants including process units, raw material and product storage, handling and transfer facilities, material handling areas, maintenance areas, solid and hazardous waste storage, treatment, and disposal, and storm water systems.Page 60 of60 PermitNo. WA0022900
The following are examples ofpollution prevention strategies that may warrant evaluation: • Improving and/or establishing new management practices and standard operating procedures addressing: increased training or supervision; improvements in inventory control, materials and waste handling, general operations, and housekeeping; preventive maintenance; and remedial measures • Process or equipment modifications, including re-engineering processes to use less toxic input materials or to utilize by-products • Material substitution • Reducing material inputs • Recycle/reuse ofrefinery waste, by-products, or process materials and fluids • Application ofwater conservation methods, including waterreuse • Waste segregation and separation • Altemative and/or enhanced treatment technology, including upstream treatment ofpollutants Cross-media shift ofpollutants should be avoided, unless a clear net environmental benefitresults and compliance with standards applicable to other media ormanagementprograms would be maintained. Prioritization & Selection ofPollution Prevention Opportunities: The plan must prioritize pollution prevention opportunities. The Permittee mustprovide their rationale for how the pollution prevention opportunities are prioritized. In addition to technical and economical feasibility, other factors may influence ranking ofopportunities and should be included in the discussion. These factors may include capital projects planned or ongoing at the refmery that will provide a benefitto environmental media otherthan water, corresponding reduction in safetyrisks, etc. Projects that achieve the highest environmental benefit must have greaterpriority. In prioritizing and selecting pollutionprevention opportunities, the Permittee must give preference first to those that eliminate, avoid, or reduce the generation ofwaterpollutants at the source, second to those that recycle orreuse the pollutants, and third to those that provide at-source or near-source treatment to remove pollutants orrender them less toxic or harmful. In ranking opportunities, the Permittee must also consider pollutant loading and toxicity and the potential to achieve the greatest reduction with respectto time and costs. The Permittee is expected to establish reasonable priorities and schedules for implementation to achieve the greatestreduction in pollutant quantity and toxicity, as well as for management and fiscal necessity.
