A. 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. 

Beginning on the effective date of this permit and lasting through the expiration 

date, the Permittee is authorized to discharge wastewater treatment plant effluent at 

the permitted location subject to complying with the following limits:

Permit No. W A0022900 

The 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. Additional allocation may 

be permitted for stormwater runoff and ballast water according to Permit Condition S l.B. 

The maximum daily effluent limit means the highest allowable daily discharge. The daily 

discharge means the discharge of a pollutant measured during a calendar day. For pollutants 

with limits expressed in units of mass, the daily discharge is calculated as the total mass of 

the pollutant discharged over the day. For other units of measurement, the daily discharge is 

the average measurement of the pollutant over the day. Additional allocation may be 

permitted for st01mwater runoff and ballast water according to Permit Condition S l.B. 

Continuous means uninterrupted except for brief lengths of time for calibration, for power 

failure, or for necessary equipment repair or maintenance. With the exception of pH, the 

Permittee must sample every 4 hours when continuous monitoring is not possible. 24-hour 

composite means a series of individual 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 been reduced as a result of consistent 

performance well below the permit limits. Should the treatment performance deteriorate 

Ecology may increase the monitoring frequencies to the levels required in the previous 

permit (COD 7/7 and Ammonia 5/7). Ecology will notify the Permittee by letter to increase 

monitoring upon determination of deteriorating performance. 

Indicates the range of permitted values. Any excursions below 5.0 and above 10.0 at any 

time are violations. The instantaneous maximum and minimum pH must be reported in the 

monthly. Do not average pH values. When pH 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 

3 0 minutes per month. 

If pH data from the continuous monitor is unavailable, pH monitoring must consist of hourly 

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 in Appendix B. The results of the analysis must be 

reported in the monthly DMR. · 

The average daily crude throughput must be reported in the 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 of these analyses to 

Ecology within 90 days of each sampling event. List the data in tabular form with the 

method, detection limit, and the measured value including units. The PCBs and pesticides 

listed in Appendix Bare not required to be tested for unless they are used at the refinery. 
Page 10 of 60 

Pem1it No. W A0022900 

B. Ballast and Stormwater Allocations (Outfall 001) 

The Permittee is authorized to discharge additional amounts of the following parameters 

based on storm water 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 with the DMR if the ballast allocation is not 

used. If the ballast water allocation is used then the Permittee must submit with the 

DMR a report showing the daily volume of ballast 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 of ballast water plus the average 

dry weather flow rate. The average dry weather flow is hereby established as 3.87 

MGD. The Permittee may only use the maximum daily storm water allocation on those 

storm water flow days when the base limits from S 1 above are exceeded. During the 

summer months of June 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. If rainfall data on-site is unavailable due to equipment malfunction, 

data from nearby rainfall gauging stations can be used.

Storm water flow is equal to the amount of flow in excess of the established dry weather 

flow plus ballast water. For the months of June 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 of storm water flows from qualifying storm water flow 
Page 11 of60 

Pe1mit No. WA0022900 

days sampled divided by the number of qualifying days times the average monthly 

allocation for that parameter. The Total Average Monthly Limit (T) is the sum of the 

base average monthly limit (B) (listed in Condition S l.A.) plus the Average Monthly 

Stormwater Allocation (listed in ConditionS l.B.) T = B + AMSWA. (An example 

calculation is shown in Appendix B). 

C. Stormwater Benchmarks, Prohibitions and Monitoring Requirements Outfalls (002, 

003, 004, 005 and 007) 

1. Authorized Stormwater and Non-Stormwater Discharges 

Beginning on the effective date of this pe1mit and lasting through its expiration 

date, the Pennittee is authorized to discharge stormwater and conditionally 

approved non-stormwater discharges (Non-Routine and Unanticipated Discharges, 

Condition S6.) from Outfalls 002, 003, 004, 005, and 007 to waters of the state. All 

discharges and activities authorized by this permit must be consistent with the 

terms and conditions of this permit. 

2. General Prohibitions 

The Permittee must manage all stormwater discharges to prevent the discharge of: 

crude, synthetic or processed oil, or oil-containing products as identified by an oil 

sheen. 

3. Monitoring Requirements 

Beginning on the effective date of this permit, the Pe1mittee must monitor 

stormwater from Outfalls 002, 003, 004, 005, and 007 for the parameters listed in 

the following tables. Additional monitoring requirements for Outfalls 003 and 006

described below 

a The Permittee may petition Ecology to reduce or suspend monitoring 

for one or more of these parameters upon consistent attainment of benchmark 

values. Consistent attainment is defined as eight consecutive quarters where 
Page 12 of 60 

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 or permit limits. They are 

indicator values. Values at or below the benchmark are considered unlikely to 

cause a water quality violation. 

If there 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 each year. "First fall storm event" 

means the first time after October 1st of each year that precipitation occurs and 

results in a stormwater discharge from a facility. 

The Permittee must collect smnples within the first 12 hours of stormwater 

discharge events. If it is not possible to collect a sample within the first 12 hours 

of a stormwater discharge event, the Permittee must collect the smnple as soon as 

practicable after the first 12 hours, and keep documentation with the sampling 

records explaining why they could not collect samples within the first 12 hours. 

The Permittee is not required to sample outside of regular 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 if the Permittee collected the sample within 

the first 12 hours of stormwater discharge events. 

d. An explanation of why it could not collect a sample within the first 12 

hours of a storm water discharge event, if it was not possible. 

e. Sample location (using SWPPP identifying number). 

f. Method of sampling, and method of smnple preservation, if 

applicable. 

g. Individual who performed the sampling. 

If no storm water smnple was sampled from the site during a given reporting 

period, the Permittee must submit the report indicating "no sample 

sampled", or "no discharge during the quarter", as applicable. 
Page 13 of 60 

Permit No. W A0022900 

The Pe1mittee must conduct and document visual inspections of Outfalls 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 of illicit 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. 

If an illicit discharge is discovered, the Permittee must notify Ecology within 7 

days. The Permittee must eliminate the illicit discharge within 30 days. 

The Permittee must record the results of each inspection including: 

a. Time and date of the inspection 

b. Locations inspected. 

c. Any observations of non-compliance and the remedial actions the Permittee 

plans to take to resolve the non-compliance. 

d. Name, title, and signature of the person conducting the inspection. 

The Permittee must submit the results of quarterly storm water monitoring and 

monthly inspections to Ecology by the due dates below: 

Reporting Period ' ' 

----•_ Month,s .· ·. .-. . Quarterly Results 

1st Quarter January, February, March May 15 

2nd Quarter April, May, June August 15 

3rd Quarter July, August, September November 15 

4th Quarter October, November, December February 15 

4. Response to Monitoring Results Above Benchmark Values 

Each time that sampling results are above a benchmark value or outside the 

benchmark range for pH, the Permittee must take the following actions: 

a. Conduct an inspection of the drainage area for the affected outfall as promptly 

as possible but no later than two weeks after receipt of sampling results. 

b. Identify the possible sources of stormwater contamination from industrial 

activity that are causing or contributing to the elevated levels of the benchmark 

parameter. 

c. Evaluate whether any improvements or changes to existing best management 

practices (BMPs) or additional operational source control, structural source 
Page 14of60 

Pennit No. 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 of additional 

controls is not feasible or not necessary to prevent discharges that may cause or 

contribute to a violation of water quality standard. 

e. Include a brief summary of inspection 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 via the dockside firewater 

system during monthly testing of the 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 Pond via 

Outfall 003 only during a rainfall event when there is a risk of overflowing the Final 

Holding Pond which contains treated process water. 

The Permittee is authorized to discharge stormwater at Outfall 006 to the Strait of Georgia 

during a rainfall event when there is a risk of overflowing the dock on-shore sump. 

During each event of a discharge described in this subsection, the Permittee must record 

the. estimated flow and collect daily grab samples at the location of the alternative 

stormwater discharge for turbidity, TSS, O&G, and pH analysis. The Permittee must 

notify Ecology of any storm water discharges under this subsection within 24 hours of such 

an event and submit the results of monitoring in the monthly discharge monitoring report. 

F. Mixing Zone Authorization 

MIXING ZONE FOR OUTFALL 001: 

The following paragraphs define the maximum boundaries or flow-volume restriction of 

the mixing zones: 
Page 15 of 60 

Permit No. W A0022900 

Crn:onic Mixing Zone 

The mixing zone is a circle with radius of257 feet measured from the center of each of 

the diffuser polis. The mixing zone extends from the seabed 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.

Ecology will attribute any violations of water quality or sediment quality standards 

detected in the receiving water or receiving sediments within the zone of influence of 

the combined Permittee/Praxair discharge to the Permittee, which is responsible for 

initiating any necessary corrective action. 

1. Discharge of Treated Wastewater From Praxair 

The Permittee is authorized to receive treated discharge from the Praxair, Inc. 

Ferndale Facility for conveyance through the Permittee's outfall pipeline to the 

Strait of Georgia consisting solely of: 

• Non-contact cooling tower blowdown 

• Cooling water sand filter backwash 

The Praxair discharge is subject to the terms and conditions ofNPDES Permit, 

No. WA0030350. The permit does not authorize the discharge of sanitary 

wastewaters, treated stormwater, untreated condensate from knock-out pots, and 

other effluent streams into the Permittee's outfall line from Praxair. 

In the event that Praxair ceases to discharge non-contact cooling water into the 

Permittee's outfall pipeline, the Permittee must celiify that Praxair has abandoned 

the connecting pipeline. The Permittee must submit a written notification to 

Ecology prior to the line being placed back into service once it has been taken out 

of service.

S2. MONITORING REQUIREMENTS 

A. Monitoring Schedule 

The Permittee must monitor in accordance with the schedules specified for the final 

effluent and storm water discharges in Permit Condition S 1 and the requirements 

specified in Appendix B. 
Page 17 of60 

Permit No. W A0022900 

B. Sampling and Analytical Procedures 

Samples and measurements taken to meet the requirements of tllis 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. 

After a portion of the daily sample is removed for the Permittee's analysis, the 

remainder, 2-3 gallons (minimum) must be retained until3:00 pm of the following 

day. The composite sample must be kept refrigerated at or below 6 °C in the 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 can be 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 of the Guidelines 

Establishing Test Procedures for the Analysis of Pollutants contained in 40 CFR 

Part 136.

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. If the Permittee uses micro-recording temperature devices known as 

thermistors it must calibrate the devices using protocols from Ecology's 

Quality Assurance Project Plan Development Tool (Continuous Temperature 

Sampling Protocols for the Environmental Monitoring and Trends). This 

document is available online at 

http://www.ecy.wa.gov/programs/eap/qa/docs/QAPPtool/Mod6%20Ecology% 

20SOPs/Protocols/ContinuousTemperatureSampling.pdf. Calibration as 

specified in this document is not required if the Permittee uses recording 

devices which are certified by the manufacturer.

Page 23 of60 

Pe1mit No. W A0022900 

S4. OPERATION AND MAINTENANCE 

The Permittee must, at all times, properly operate and maintain all industrial wastewater 

and storm water facilities or systems of treatment and control (and related appurtenances) 

which are installed to achieve compliance with the terms and conditions of this permit. 

Proper operation and maintenance includes adequate laboratory controls and appropriate 

quality assurance procedures. This provision requires the operation of back-up or 

auxiliary facilities or similar systems, which are installed by a Permittee when the 

operation is necessary to achieve compliance with the conditions of this 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 of the wastewater processed by the 

wastewater treatment plant. 

3. Confirm this review by letter to Ecology. 

4. Keep the approved O&M Manual at the permitted facility. 

In addition to the requirements ofWAC 173-240-150(1) and (2), the O&M manual 

must include: 

1. Emergency procedures for plant shutdown and cleanup in event of wastewater 

system upset or failure. 

2. Procedures to maintain treatment efficiency during scheduled maintenance 

operations at the wastewater treatment plant. 

For the purposes of this NPDES permit, a Treatment System Operating Plan (TSOP) is 

a concise summary of specifically defined elements of the O&M Manual. The TSOP 

must not conflict with the O&M Manual and must include the following information: 

1. A baseline operating condition, which describes the operating parameters and 

procedures, used to meet the effluent limits in Condition S 1 at the production 

levels used in developing these limits. 

2. The plan must describe the operating procedures and conditions needed to 

maintain treatment efficiency at less than design loading conditions .. 

3. In the event of an upset, due to plant maintenance activities, severe stormwater 

events, start ups or shut downs, or other causes, the plan must describe the 

operating procedures and conditions employed to mitigate the upset. 

4. A description of any regularly scheduled maintenance or repair activities at 

the facility which would significantly affect the volume or character of the 

wastes discharged to the wastewater treatment system and a plan for 

treating/controlling the discharge of maintenance-related materials (such as 
Page 24 of60 

Pe1mit No. W A0022900 

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 permit term, to include requirements for any major modifications to the 

wastewater treatment system. 

B. Bypass Procedures 

This permit prohibits a bypass which is the intentional diversion of waste streams 

from any portion of a treatment facility. Ecology may take enforcement action 

against a Permittee for a bypass unless one of the following circumstances (1, 2, 

or 3) applies. 

1. Bypass for Essential Maintenance without the Potential to Cause Violation of 

Permit Limits or Conditions. 

Bypass is authorized if it is for essential maintenance and does not have the 

potential to cause violations of limitations or other conditions of this permit, or 

adversely impact public health as determined by Ecology prior to the bypass. 

The Permittee must submit prior notice, if possible, at least ten (1 0) days 

before the date of the bypass. Notice is not required where redundant 

equipment is available to perform the functions of equipment scheduled for 

bypass during maintenance. 

2. Bypass which is Unavoidable, Unanticipated, and Results in Noncompliance of 

this Permit. 

This bypass is permitted only if: 

a. Bypass is unavoidable to prevent loss of life, personal injury, or severe 

property damage. "Severe property damage" means substantial physical 

damage to property, damage to the treatment facilities which would cause 

them to become inoperable, or substantial and permanent loss of natural 

resources which can reasonably be expected to occur in the absence of a 

bypass. 

b. No feasible alternatives to the bypass exist, such as: 

• The use of auxiliary treatment facilities. 

• Retention of untreated wastes. 

• Stopping production. 

• Maintenance during normal periods of equipment downtime, but not 

if the Permittee ·should have installed adequate backup equipment in 

the exercise of reasonable engineering judgment to prevent a bypass. 
Page 25 of60 

Permit No. W A0022900 

• Transport of untreated wastes to another treatment facility or 

preventative maintenance), or transpmi of untreated wastes to another 

treatment facility. 

c. Ecology is properly notified of the bypass as required in condition S3E of 

this permit. 

3. If bypass is anticipated and has the potential to result in noncompliance of this 

permit. 

a. The Permittee must notifY Ecology at least thirty (30) days before the 

planned date of bypass. The notice must contain: 

• ·A description of the bypass and its cause. 

• An analysis of all known alternatives which would eliminate, reduce, or 

mitigate the need for bypassing. 

• A cost-effectiveness analysis of alternatives including comparative 

resource damage assessment. 

• The minimum and maximum duration of bypass under each alternative. 

• A recommendation as to the preferred alternative for conducting the bypass. 

• The projected date of bypass initiation. 

• A statement of compliance with SEP A. 

• A request for modification of water quality standards as provided for in 

WAC 173-201A-41 0, if an exceedance of any water quality standard is 

anticipated. 

• Details of the steps taken or planned to reduce, eliminate, and prevent 

reoccurrence of the bypass. 

b. For probable construction bypasses, 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 construction period in an effort to 

minimize or eliminate the bypass. 

c. Ecology will consider the following prior to issuing an administrative order 

for this type of bypass: 

• If the bypass is necessary to perform construction or maintenance-related 

activities essential to meet the requirements of this permit. 

• If feasible alternatives to bypass exist, such as the use of auxiliary 

treatment facilities, retention of untreated wastes, stopping production, 

maintenance during normal periods of equipment down time, or transport 

of untreated wastes to another treatment facility. 
Page 26 of60 

Permit No. WA0022900 

• If the Permittee planned and scheduled the bypass to minimize adverse 

effects on the public and the environment. 

After consideration of the above and the adverse effects of the 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 of significant 

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 or prevent any 

discharge or sludge use or disposal in violation of this permit that has a reasonable 

likelihood of adversely affecting human health or the environment. 

SS. FACILITY LOADING 

A. Design Criteria 

The flows or waste loads for the permitted facility must not exceed the following 

design criteria: 

Parameter Design Quantity 

Daily Maximum Flow from 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 submit to Ecology a plan and a schedule for continuing to 

maintain capacity when: 

1. The actual flow or waste load reaches 85 percent of any one of the design criteria 

in S5.A for three consecutive months; or 

2. The projected increase would reach design capacity within five years, 

whichever occurs first. 

If such a plan is required, it must contain provisions and a schedule for continuing to 

maintain capacity. The capacity as outlined in this plan must be sufficient to achieve 

the effluent limitations and other conditions of this permit. The plan must address the 

following actions and any others necessary to meet the objective of maintaining 

capacity. 

1. Analysis of the present design including the introduction of any process 

modifications that would affect the ability of the existing facility to achieve 

effluent limits and other requirements of this permit at levels in excess of the 

existing design criteria specified in paragraph A, above. 
Page 27 of 60 

Permit No. WA0022900 

2. Reduction or elimination of excessive infiltration and inflow into the sewer system. 

3. Limitation on future additional waste loads. 

4. Modification or expansion of facilities 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 on the effective date of this 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 by Ecology. Prior to any such discharge, the Permittee must contact 

Ecology and at a minimum provide the following information: 

1. The proposed discharge location. 

2. The nature of the activity that will generate the discharge. 

3. Any alternatives to the discharge, such as reuse, storage, or recycling 

ofthe water. 

4. The total volume of water it expects to discharge. 

5. The results of the chemical analysis of the 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 by Ecology. All discharges must comply with the 

effluent limits as established in Condition S 1. of this permit, water 

quality standards, and any other limits imposed by Ecology. 

6. The date of proposed discharge. 

7. The expected rate of discharge discharged, in gallons per minute. 

The Permittee must limit the discharge rate so it will not cause 

erosion of ditches or structural damage to culverts and their 

entrances or exits. 

B. The discharge cannot proceed until Ecology has reviewed the information provided 

and has authorized the discharge by email/letter to the Permittee or by an 

Administrative Order. 
Page 28 of60 

Permit No. W A0022900 

S7. ACUTE TOXICITY 

A. Effluent Limit for Acute Toxicity 

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 S 1.F of this permit. The 

ACEC equals 3.6% effluent. 

B. Compliance With the Effluent Limit for Acute Toxicity 

Compliance with the effluent limit for acute toxicity means the results of the testing 

specified in subsection C. show no statistically significant difference in survival 

between the control and the ACEC. 

If the test results show a statistically significant difference in survival between the 

control and the ACEC, the test does not comply with the effluent limit for acute 

toxicity. The Permittee must then immediately conduct the additional testing described 

in subsection D. The Permittee will comply with the requirements of this section by 

meeting the requirements of subsection D. 

The Permittee must determine the statistical significance by conducting a hypothesis 

test at the 0.05 level of significance (Appendix H, EPA/600/4-89/001). Ifthe difference 

in survival between the control and the ACEC is less than 10%, the Permittee must 

conduct the hypothesis test at the 0.01 level of significance. 

C. Compliance Testing for Acute Toxicity 

The Permittee must: 

1. Begin compliance testing by May 1, 2012. Perform the acute toxicity tests 

with 100% effluent, the ACEC, and a control, or with a full dilution series. 

2. Submit a written report of all test results to Ecology within sixty (60) days 

after completion of the test. 

The Permittee must perform compliance tests quarterly using each of the species and 

protocols listed below on a rotating basis: 

Acute Toxicity Tests Species Method

······ 

D. Response to Noncompliance with the Effluent Limit for Acute Toxicity 

If a toxicity test conducted under subsection C. determines a statistically significant 

difference in response between the ACEC and the control, using the statistical test 

described in subsection B., the Permittee must begin additional testing within one week 

from the time of receiving the test results. 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 of these effluent concentrations must 

equal the ACEC. The results of the test at the ACEC will determine 

compliance with the effluent limit for acute toxicity as described in 

Subsection B. 

3. Return to the original monitoring frequency in Subsection C. after 

completion of the additional compliance monitoring. 

Anomalous test results: If a toxicity test conducted under subsection C. 

indicates noncompliance with the acute toxicity limit and the Permittee believes 

that the test result is anomalous, the Permittee may notify Ecology that they 

believe the compliance test result is anomalous. The Permittee should conduct 

one additional test then wait for notification from Ecology before completing the 

additional testing required above. 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 Ecology determines that the test result was not anomalous, the Permittee must 

complete all of the additional monitoring required in this subsection. Or, 

If the one additional test fails to comply with the effluent limit for acute toxicity, 

then the Permittee must complete all of the additional monitoring required in this 

subsection. Or, 

If Ecology determines that the test result was anomalous, the one additional test 

result will replace the anomalous test result. 

If all of the additional testing complies with the permit limit, the Permittee must submit 

a report to Ecology on possible causes and preventive measures for the transient toxicity 

event, which triggered the additional compliance monitoring. This report must be based 

upon a review of all pertinent and recent facility records, including: 
Page 30 of60 

Petmit No. W A0022900

2. Monitoring results 

3. Inspection records 

4. Spill repmis 

5. Weather records 

6. Production records 

7. Raw material purchases 

8. Pretreatment records, etc. 

If any 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, then the test result is a violation of the acute limit. 

E. Sampling and Reporting Requirements 

1. The Permittee must submit all reports for toxicity testing in accordance with the 

most recent version of Department of Ecology Publication No. WQ-R-95-80,

in the most recent versions of the EPA methods listed in subsection C. and Ecology 

of Ecology Publication# WQ-R-95-80, Laboratory Guidance and Whole Effluent 

Toxicity Test Review Criteria. If Ecology 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 

of the EPA methods listed in subsection C. or pristine natural water of sufficient 

quality for good control performance. 

6. The Permittee must conduct whole effluent toxicity tests on an unmodified sample 

of final effluent. 
Page 31 of60 

Permit No. W A0022900 

7. The Petmittee may choose to conduct a full dilution series test during compliance 

testing in order to determine dose response. In this case, the series must have a 

minimum of five effluent concentrations and a control. The series of 

concentrations must include the acute critical effluent concentration (ACEC). The 

ACEC equals 3.6% effluent. 

8. All whole effluent toxicity tests, effluent screening tests, and rapid screening tests 

that involve hypothesis testing must comply with the acute statistical power 

standard of 29% as defined in WAC 173-205-020. If the test does not meet the 

power standard, the Permittee must repeat the test on a fresh sample with an 

increased number of replicates to increase the power. 

9. Reports of individual characterization or compliance test results must be submitted 

to Ecology within 60 days after completion of the test. 

S8. . CHRONIC TOXICITY 

A. Testing When There Is No Permit Limit for Chronic Toxicity

and once in the last winter prior to submission of the permit renewal 

application. 

2. Submit the results to Ecology with the permit renewal application. 

3. Conduct chronic toxicity testing on a series of at least five concentrations of 

effluent and a control. This series of dilutions must include the acute critical 

effluent concentration (ACEC). The ACEC equals 3.6% effluent. 

4. Compare the ACEC to the control using hypothesis testing at the 0.05 level 

of significance as described in Appendix H, EP A/600/4-89/00 1. 

5. Perform chronic toxicity tests with all of the following species and the most 

recent version of the following protocols:

Permit No. W A0022900 

Laboratory Guidance and Whole Effluent Toxicity Test Review Criteria. The 

laboratory must use whichever one of the two species that will give a valid result in 

each particular test. 

Anomalous test results: If the 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 of the test result and identifY the reason for considering 

the compliance test result to be anomalous. The Permittee should conduct one 

additional test and submit that result as well to Ecology. 

If Ecology determines that the test result was not anomalous, the test result will be 

used for characterizing the effluent and for making future chronic toxicity limit 

determinations. If Ecology determines that the test result was anomalous, the one 

additional test result will replace the anomalous test result. 

B. Sampling and Reporting Requirements 

1. The Permittee must submit all reports for toxicity testing in accordance with the 

most recent version of Ecology Publication No. WQ-R-95-80, Laboratory 

Guidance and Whole Effluent Toxicity Test Review Criteria. Reports must contain 

toxicity data, bench sheets, and reference toxicant results for test methods. In 

addition, the Permittee must submit toxicity test data in electronic format (CETIS 

export file preferred) for entry into Ecology's database. 

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 begin the toxicity testing as soon as possible but no later than 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 in the most recent version of Ecology

Page 33 of 60 

Permit No. W A0022900 

7. 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 of five 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 of effluent during 

critical conditions at the boundary of the mixing zone, defined in Section S 1.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

S9. WASTEWATER TREATMENT EFFICIENCY STUDY AND UPDATED 

ENGINEERING REPORT 

Ecology will require a wastewater treatment efficiency study if the Permittee proposes 

material and substantial alterations to the refinery that could cause a material change in 

the quantity or composition of the influent processed by the wastewater treatment 

system. In the event that Ecology requires a treatment efficiency study, the Permittee 

must prepare and submit a study plan for Ecology's review and approval. The 

Permittee must submit the plan within 90 days of startup of the material and substantial 

alterations to the refinery. 

In addition, the Permittee must update the engineering report for the wastewater

the update to Ecology for review and approval within 180 days after completion of the 

treatment efficiency study. 

SlO. SEDIMENT MONITORING 

The Permittee must submit a Sediment Sampling and Analysis Plan to recharacterize 

sediment toxicity in the vicinity of Outfall 001 to Ecology for review and approval. 

The Permittee must recharacterize sediment toxicity at the North Pier if Ecology 

determines that significant spills or accumulation of spills have occurred since the 

2006 baseline sediment characterization. A decision will be made by Ecology as to 

whether a reported spill or accumulation of spills is significant enough to warrant 

additional sediment sampling at the North Pier. The purpose of the plan is to 

recharacterize sediment toxicity in the Permittee's discharge location between August 

15th and September 15th. 
Page 34 of60 

Pennit No. 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 cunent Puget Sound 

Estuary Program Protocols.

C. The Permittee must submit a Sediment Data Report containing the results of the 

sediment sampling and analysis no later than 180 days after completion of sampling. 

The Sediment Data Report must also include electronic copies of the sediment 

chemical and/or biological data formatted according to Ecology's Environmental 

Information Management (EIM) System templates. 

Sll. POLLUTION PREVENTION 

Pollution prevention planning and activities at the facility include the: 

• New pollution prevention projects identified for the upcoming permit cycle in 

the plan update. 

• Standard Operating Procedures (SOPs), Best Management Practices (BMPs), 

and work practices developed and updated from previous permit pollution plans, 

stormwater pollution prevention plans (SWPPPs), solid waste control plans, and 

spill plans. 

The Permittee must continue to ensure proper operation and maintenance of the refinery 

process units and wastewater treatment system by following existing SOPs, BMPs, and 

work practices. The Permittee must continue or maintain these procedures and other 

measures and/or facilities cunently employed at the refinery to prevent or minimize the 

potential for release of pollutants to the wastewater treatment system, storm water, 

and/or waters of the state unless modified by the pollution prevention plan update 

required below. 

Storm water 

Stormwater BMPs must: 

• Provide all known, available, and reasonable methods of prevention, 

control, and treatment (AKART) of stormwater pollution. 

• Ensure the discharge does not cause or contribute to a violation of the 

Water Quality Standards. 
Page 35 of 60 

Permit No. W A0022900 

• 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 of pollution 

prevention approved by Ecology. 

The Permittee must handle and dispose of all 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 of treatment, 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 or permit modification as may be required for such discharges to 

state ground or surface waters. 

Storage Tank Wastewater 

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. Pollution Prevention Plan Update and Implementation 

The Permittee must update its Pollution Prevention Plan and submit it to Ecology 

for review and approval by September 1, 2013. The Permittee must implement the 

approved pollution prevention plan update and any approved modifications to the 

plan and abide by the timefrarnes identified throughout the tetm of the permit. 

The objective of this update is to identifY any new sources of pollutants, to 

reevaluate previously identified pollution prevention opportunities and to identifY 

any new opportunities and implement those that are technically and economically 

achievable. Previously identified opportunities include those identified by the 

facility in their current Pollution Prevention plan and those identified in Ecology 

Publication 02-07-017 (Water Pollution Prevention Oppmiunities in Petroleum 

Refineries). The update must also include an evaluation of the existing SOPs, 

BMPs, and work practices developed under previous pollution prevention 

planning/activities. 

Specifically, the Permittee should evaluate the following pollution prevention 

opportunities: 1) lining the wastewater and stormwater treatment ponds, 

2) increasing the removal efficiency of TSS in the wastewater and storm water 

treatment trains, and 3) evaluating the potential to remove mercury, copper, 

and dioxin from the process wastewater. 
Page 36 of60 

Permit No. W A0022900 

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 of current pollution prevention activities, and the 

description of potential 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 pollution prevention opportunities. Other 

information available to the Permittee may also be used in preparing the plan. 

The updated plan must include a schedule for implementation of each newly 

selected opportunity. If a detailed analysis of technical and economical feasibility 

for any pollution prevention opportunity will extend beyond the deadline for 

submitting the updated plan, 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 if the 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 modify the plan as necessary to include additional or 

modified BMPs designed to correct problems identified. 

The Permittee must modifY the plan whenever there is a change in design, 

construction, operation, or maintenance at the facility that significantly changes the 

nature of pollutants in wastewater or stormwater from the facility, significantly 

increases the quantity of pollutants discharged, or causes the pollution prevention 

plan and existing SOPs, BMPs, or work practices to be less effective in controlling 

pollutants. The Permittee must provide for implementation of any modifications to 

the pollution prevention plan in a timely manner. 

The Permittee must periodically evaluate and modifY, as necessary, the pollution 

prevention plan and existing SOPs, BMPs, and work practices to ensure that it has 

been updated or otherwise modified to reflect current conditions, that measures to 

reduce or eliminate pollutant loadings selected in the plan are adequate and are 

being properly implemented in accordance with the terms of the permit, and 

whether any additional controls are needed. 

C. Stormwater Inspections 

The Permittee must conduct two stormwater inspections per year; one during 

the wet season (October 1 - April 30) and the other during the dry season 

(May 1 - September 30). 

The Permittee must conduct the wet season inspection during a rainfall event and 

must include observations of the presence of any floating materials, suspended 
Page 37 of 60 

Permit No. 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 of unpennitted nonstormwater discharges such as sanitary wastewater, non-contact cooling water, 

process wastewater, and drainage from raw material/product/waste storage to the 

stormwater drainage system. If an unpermitted, non-stmmwater discharge is 

discovered, the Petmittee must immediately notify Ecology. 

Inspections must be conducted by personnel who are knowledgeable and trained in 

the application ofBMPs and pollution prevention activities at the refinery. Results 

from the stormwater visual inspections must be reported in the pollution prevention 

plan biennial update reports. 

D. Biennial Reporting 

The Permittee must submit a biennial progress report by September 1st (within 2 years 

after submittal of the updated Pollution Prevention Plan required in Condition Sl2.A.) 

and every two years thereafter. The report must identify the implementation status of 

each pollution prevention opportunity selected, the benefits or other results of 

implementation actions completed, and any modifications or updates to the plan. The 

report must also include a summary of the results of storm water inspections. 

E. Continuous Improvement 

In maintaining, implementing, and updating the pollution prevention plan, the 

Permittee should employ continuous improvement principles, including the 

systematic and ongoing identification, evaluation, and implementation of pollution 

prevention opportunities in all decisions having environmental consequences.

Page 43 of60 

Permit No. W A0022900 

C. The following are causes for modification or alternatively revocation and reissuance: 

1. Cause exists for te1mination for reasons listed in A 1 through A 7 of this section and 

Ecology determines that modification or revocation and reissuance is appropriate. 

2. Ecology has received notification of a proposed transfer of the pern1it. A permit 

may also be modified to reflect a transfer after the effective date of an automatic 

transfer (General Condition G8) but will not be revoked and reissued after the 

effective date of the transfer except upon the request of the new permittee. 

G4. REPORTING PLANNED CHANGES 

The Permittee must, as soon as possible, but no later than thirty (30) days prior to the 

proposed changes, give notice to Ecology of planned physical alterations or additions to 

the permitted facility, production increases, or process modification which will result in: 

1) the permitted facility being determined to be a new source pursuant to 40 CFR 

122.29(b); 2) a significant change in the nature or an increase in quantity of pollutants 

discharged; or 3) a significant change in the Permittee's sludge use or disposal 

practices. Following such notice, and the submittal of a new application or supplement 

to the existing application, along with required engineering plans and repmis, this 

permit may be modified, or revoked and reissued pursuant to 40 CFR 122.62(a) to 

specify and limit any pollutants not previously limited. Until such modification is 

effective, any new or increased discharge in excess of permit limits or not specifically 

authorized by this permit constitutes a violation. 

GS. PLAN REVIEW REQUIRED 

Prior to constructing or modifying any wastewater control facilities, an engineering 

report and detailed plans and specifications must be submitted to Ecology for approval

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 and every 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 limitations 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 limitations 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: 1) 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 condition S3 .E; and 4) the 

Permittee complied with any remedial measures required under S4.C of this permit.

In any enforcement proceeding the Permittee seeking to establish the occurrence of an 

upset has the burden of proof. 

G16. PROPERTY RIGHTS 

This petmit 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 

enforcement action; for permit termination, revocation and reissuance, or modification; 

or denial of a permit renewal application. 

G18. TOXIC POLLUTANTS 

The Pe1mittee 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.

APPENDIX A- CALCULATING STORMW ATER AND BALLAST WATER ALLOCATIONS 

CALCULATING STORMWA TER AND BALLAST WATER ALLOCATIONS 

S l.A effluent limitations in the BP NPDES permit are base permit limits that apply to process water 

flow- these values are fixed. 

S l.C. effluent limitations in the BP NPDES permits are used to calculate incremental limits that apply to 

storm water and ballast water- the S l.C. limitations are actually multipliers. The incremental limit 

calculated using one of the multipliers is added to the base pennit limit for commingled discharges. 

Storm water flow is calculated by the subtraction of an estimated dry weather flow and ballast water flow 

from the total flow discharged each day. 

Ballast water 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 CPR 419.12(c) and 419.22(e). The 

allocations for storm water are intended to apply to runoff from 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 permit limitations 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 that measurable 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. If the storm water allocation can be claimed 

per the conditions of the 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 with the maximum daily permit limitation- on a day by day basis compare the 

maximum discharge for a parameter to the base permit limitation plus the storm water allocation and/or 

ballast water allocation calculated for that parameter. 

Example Calculation 1. 

Dry weather flow: 1 MGD 

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/day 
Page 49 of60 

Permit No. W A0022900 

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. If ballast 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 of days. 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: 1 MGD 

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 water flow 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 greater than 210, the TSS average monthly permit limit is exceeded. 

If ballast water had also been a factor in Example Calculation 2, the average monthly permit limit would 

not have been exceeded. 

Ballast water 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/day

Permit No. W A0022900 

APPENDIX B -LIST OF POLLUTANTS WITH ANALYTICAL METHODS, 

DETECTION LIMITS 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 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 

repmi. 

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. 

Ecology added this appendix to the permit in order to reduce the number of analytical "nondetects" in permit-required monitoring and to measure effluent concentrations near or below 

criteria values where possible at a reasonable cost.

1. 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 dete1mined by the procedure given in 40 CFR part 136, 

Appendix B. 

2. Quantitation Level (QL) also known as Minimum Level ofQuantitation (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 lOn, 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).

APPENDIX C- REFINERY NPDES POLLUTION PREVENTION PLANS- SPECIFIC 

REQUIREMENTS 

GUIDANCE DOCUMENTS 

Guidance available to develop a pollution prevention plan include the Guidance Manual for 

Preparing/Updating a Stormwater Pollution Prevention Plan for Industrial Facilities, Apri12004 

(Ecology Publication No. 04-1 0-030), the 2005 Storm water Management Manual for Western 

Washington Apri12005 (Ecology Publication No. 05-10-029), the 'Pollution Prevention and Best 

Management Practices' section of the Water Quality Program Permit Writer's Manual-Chapter XII, 

revised November 2010 (Ecology Publication No. 92-1 09), An Organizational Guide to Pollution 

Prevention,July 2001 (EPA-625-R-01-003), the methodologies of pollution prevention planning 

references available at http://www.ecy.wa.gov/programs/hwtr/p2/p3.html, and other information 

provided by the Ecology Permit Manager. 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 of the 

WAC 173-307 guidance. 

PLAN & PLAN IMPLEMENTATION REQU1REMENTS 

Policy Statement and Signature: 

The pollution prevention plan must include a policy statement articulating management and corporate 

support for the plan and a commitment to implement the plan and to continued pursuit of pollution 

prevention opportunities. The plan, plan updates, and modifications must be signed in accordance with 

Permit Condition G 1. 

Employee Involvement, Training, and Awareness: 

The pollution prevention plan must include a description of personnel training and employee involvement 

programs that emphasize pollution prevention and solicit employee ideas about pollution prevention 

opportunities and other environmental issues. Staff training records must be maintained onsite and be 

available for inspection. 

Description of Current Pollution Prevention Activities: 

Stormwater Pollution Prevention 

The pollution prevention plan must include stormwater pollution prevention requirements consistent with 

the requirements for a Stormwater Pollution Prevention Plan (Condition S3.) in Ecology's Industrial 

Stormwater General Permit, effective January 1, 2010. 

The plan must include a description of preventive measures and facilities already employed at the refinery 

to prevent, reduce, eliminate, or control releases of pollutants to influent wastewater streams, storm water, 

and/or waters of the state. 

Incorporating Other Pollution Prevention Plans 

The Permittee may incorporate applicable portions of plans prepared for other purposes. Plans or portions 

of plans incorporated into the pollution prevention plan become enforceable requirements of this permit. 
Page 59 of60 

Pem1it No. W A0022900 

Description of Potential Pollutants and Sources: 

The pollution prevention plan must include a detailed description of the 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 of at the facility and the pollutants that are 

generated or potentially generated or released. The level of detail 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 must be 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) or Extremely 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 Permittee must use available 

sampling data, as well as knowledge of processes and materials, and available information on the relative 

toxicity or hazard of materials. Sources ofPBTs must be included in the analysis. The Permittee must 

not be required to sample each stream analytically and may use engineering judgment to assess and 

quantify material inputs and outputs on a process unit basis. 

Identification & Preliminary Evaluation of Pollution Prevention Opportunities: 

The plan must identify pollution prevention opportunities and provide a detailed analysis of each 

opportunity's technical (including safety considerations) and economic feasibility. Opportunities 

determined to be technically 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 

of the amount of pollutants reduced, and the environmental or other benefits that will be achieved. 

The Permittee must concentrate on opportunities that reduce or eliminate PBTs, priority pollutant metals, 

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 consider the 

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 of the 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 

Permit No. W A0022900 

The following are examples of pollution 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 of refinery waste, by-products, or process materials and fluids 

• Application of water conservation methods, including water reuse 

• Waste segregation and separation 

• Altemative and/or enhanced treatment technology, including upstream treatment of pollutants 

Cross-media shift of pollutants should be avoided, unless a clear net environmental benefit results and 

compliance with standards applicable to other media or management programs would be maintained. 

Prioritization & Selection of Pollution Prevention Opportunities: 

The plan must prioritize pollution prevention opportunities. The Permittee must provide their rationale 

for how the pollution prevention opportunities are prioritized. In addition to technical and economical 

feasibility, other factors may influence ranking of opportunities and should be included in the discussion. 

These factors may include capital projects planned or ongoing at the refmery that will provide a benefit to 

environmental media other than water, corresponding reduction in safety risks, etc. Projects that achieve 

the highest environmental benefit must have greater priority. 

In prioritizing and selecting pollution prevention opportunities, the Permittee must give preference first to 

those that eliminate, avoid, or reduce the generation of water pollutants at the source, second to those that 

recycle or reuse the pollutants, and third to those that provide at-source or near-source treatment to 

remove pollutants or render 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 respect to 

time and costs. 

The Permittee is expected to establish reasonable priorities and schedules for implementation to achieve 

the greatest reduction in pollutant quantity and toxicity, as well as for management and fiscal necessity.
