SPECIAL CONDITIONS 

Sl. DISCHARGE LIMITATIONS 

In this permit the word "must" denotes an action that is mandatory and is equivalent to the word 

"shall" used in previous permits. 

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 is a violation of 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 treated effluent at the permitted location subject 

to complying with the following limitations:

DMR. 

Feedstock Rate bbls per There is no limitation for this parameter. The 

barrels stream day monthly average must be repotied in the cover 

letter of the monthly DMR. 

pH pH must be maintained within the range of 6.0 to 9.0. 

pH must be continuously recorded. Excursions between 5.0 and 

6.0, or 9.0 and 10.0 must not be considered violations provided no 

single excursion exceeds 60 minutes in length and total excursions 

do not exceed 7 hours and 30 minutes per month. Any excursions 

below 5.0 and above 10.0 are violations. The instantaneous 

maximum and minimum pH must be reported monthly. In the 

event of a failure of continuous monitoring equipment and upon 

this discovery, hourly grab samples will meet the frequency 

requirements or an alternative may be recommended subject to 

approval by the department. 

a The average monthly effluent limitation is defined as the highest allowable average of 

daily discharges over a calendar month, calculated as the sum of all daily discharges 

measured during a calendar month divided by the number of daily discharges measured 

during that month. 

b The maximum daily effluent limitation is defined as the highest allowable daily 

discharge. The daily discharge means the discharge of a pollutant measured during a 

calendar day. For pollutants with limitations expressed in units of mass, the daily 

discharge is calculated as the total mass ofthe pollutant discharged over the day. For 

other units of measurement, the daily discharge is the average measurement of the 

pollutant over the day. The pH must not be averaged.

Permit No. WA-000178-3 

B. Mixing Zone Descriptions 

The maximum boundaries of the mixing zones for outfall No. 001A are defined as 

follows: 

Chronic Mixing Zone 

WAC 173-201A-100(4)(b)(i) specifies mixing zones must not extend in any horizontal 

direction from the discharge ports for a distance greater than 200 feet plus the depth of 

water over the discharge ports as measured during mean lower low water (MLL W), and 

must not occupy greater than twenty-five percent of the width of the water body as 

measured during MLL W. The mixing zone extends from the seabed to the top of the 

water surface. Given a MLL W water depth of 0 feet (0 meters) for the Permittee's 

Outfall, the horizontal distance therefore is 200 feet (61meters). The mixing zone is a 

circle (a portion of a circle) with radius of 200 feet ( 61 meters) measured from the 

center of the discharge slot. The mixing zone extends from the seabed to the top of the 

water surface. Chronic aquatic life criteria and human health criteria must be met at the · 

edge of the chronic zone. 

Acute Mixing Zone 

WAC 173-201A-100(8)(b) specifies that in estuarine waters a zone where acute criteria 

may be exceeded must not extend beyond 10% of the distance established for the 

maximum or chronic zone as measured independently from the discharge port. The 

acute zone therefore extends 20 feet (6.1 meters) from the center of the discharge slot. 

The mixing zone extends from the seabed to the top of the water surface. Acute aquatic 

life criteria must be met at the edge of the acute zone. 

Dilution Factors 

Acute Aquatic Life Criteria 2.0 

Chronic Aquatic Life Criteria 71.3 

Human Health Criteria- Carcinogen 71.3 

Human Health Criteria-Non-carcinogen 71.3 

C. Stormwater Allocation (Outfall 001 A) 

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

based on stormwater flow through Outfall 001A. During the months of June through 

September the permittee must only be allowed to claim the stormwater allocation 

when it can be demonstrated that measurable rainfall occurred at the refinery site in 

the previous ten calendar days. If rainfall data on-site is unavailable due to equipment 

malfunction, data from nearby rainfall gauging sites can be used. In the event that a large 

stormwater inventory must be released during the months of June through September, the 

Permittee can submit operational data supporting use of the storm water allocation to the 

Department with the DMR. Upon receipt of the supporting data, the Department will 
Page 10 of 50 

Permit No. WA-000178-3 

determine if the use of the storm water allocation is appropriate and notify the Permittee by 

letter. 

The stormwater flow rate must be defined as the difference between total measured effluent 

through Outfall 001A and the average dry weather flow rate. The average dry weather flow 

is hereby established as 326,900 gallons per day (227 gpm).

Biochemical Oxygen 220 400 

Demand (5-Day) 

Chemical Oxygen Demand 1500 3000 

Total Suspended Solids 180 280

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

flow. For the months of June through September, qualifying storm water flow days are only 

those days when measurable rainfall occurred at the refinery site during the previous 

1 0 calendar days. 

Average Monthly Stormwater Allocation (AMSWA) is defined as the sum of measured 

storm water flows from qualifying storm water flow days divided by the number of 

qualifying days times the average monthly allocation for that parameter. 

The Total Average Monthly Limitation (T) is the sum of the base average monthly limit (B) 

(listed in Condition S 1. A) plus the Average Monthly Storm water Allocation. T = B + AMSW A 

D. Marine Terminal Stormwater and Monitoring Requirements (Outfall 003) 

The discharge of any of the pollutants in the following table more frequently than, or at a level in 

excess of, that authorized by this permit must constitute a violation of the terms and conditions 

of this permit. 

No sampling for the following parameters is required during any month without discharge to 

Outfall 003. All of the information required by the following table must be reported on the 

monthly DMR for the month in which the sampling was conducted.

attainment of benchmark values. Consistent attainment is defined as eight consecutive samples in which the 

collection of the samples is spread out over a minimum of eight quarters and where the reported values do not 

exceed benchmark values. · 

b. If there is no discharge during regular business hours for an entire quarter, the Permittee must submit a report to 

Ecology stating that no discharge occurred. 

The Permittee must: 

Ill Collect samples that are representative of the flow and characteristics of 

the discharge. 

• Visually monitor the discharge at the time of sample collection. Visual 

monitoring must include observations of the presence of floating 

materials, visible sheen, discoloration, turbidity, odor, etc. in the 

stormwater discharge. 

• Evaluate during each sample collection whether or not stormwater best 

management practices established· by the Pollution Prevention Plan are in 

place and/or are being followed. 

11 Submit evaluations and visual monitoring observations with the Discharge 

Monitoring ~ep?rt. 

The Permittee is not required to sample outside of regular business hours 

(Monday-Friday, 8:00 to 5:00) or during unsafe conditions. 

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, no later than a week after receipt of sampling results. 
Page 13 of50 

Permit No. WA-000178-3 

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. Investigate and select all applicable and appropriate options for capital Best 

Management Practices, (BMPs) and operational source control BMPs to 

reduce stormwater contamination below benchmark values. Any elevated 

COD or TSS levels attributable to vegetative or naturally-occurring 

conditions do not require additional BMPs. 

d. Within 60 days of receipt of sample results complete/implement the 

additional operational source control BMPs identified in subsection c above. 

e. Within 6 months of receipt of sampling results complete 

installation/construction of the additional capital BMPs identified in 

subsection c above. If additional time is needed for construction the 

permi~ee must submit to Ecology a schedule for review and approval. 

f. 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. 

F. Clean Water Discharge 

Beginning on the effective date of this permit, the Permittee may discharge clean water, 

such as storage tank hydro test water, through Outfalls OO.lB, 002, and 003, on a case-bycase basis. Prior to any such discharge, the Permittee must contact Ecology and at a 

minimum provide the following information: 

1. The nature of the activity that is generating the discharge. 

2. The total volume of water expected to be discharged. 

3. The results of the chemical analysis of the water. The water must be analyzed 

for the following constituents: COD, TSS, Oil and Grease, Ammonia as Nand 

pH. The analysis must also include any other parameter deemed necessary by 

the Department. 

4. The rate at which the water will be discharged, in gallons per minute. The 

discharge rate must be limited to that which will not cause erosion of ditches or 

structural damage to culverts and their entrances or exits. 

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

water. 

The discharge may not proceed until the Department has reviewed the information provided 

and has authorized the discharge. Authorization from the Department will be verbal 

followed by a letter or email to the Permittee. 

G. Firewater Clean Water Discharge

grab once every 4 hours when continuous monitoring is not possible. For flow, process 

monitoring data can be used during times of instrument malfunction. 

B. Sampling and Analytical Procedures 

Samples and measurements taken to meet the requirements of this permit must be 

representative of 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 composite sample is removed for the Permittee's analysis, the 

remainder, a minimum of2 gallons, must be retained until3:00 P.M daily. The composite 

sample must be kept refrigerated at or below 4° centigrade 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. 

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. 

C. Flow Measurement 

The Permittee must select and use appropriate flow measurement devices and methods 

consistent with accepted scientific practices. The Permittee must install, calibrate, and 

maintain the flow devices. This work is necessary to ensure that the accuracy of the 

measurements is consistent with the accepted industry standard and the manufacturer's 

recommendation for that type of device. The Permittee must perform calibration at the 

frequency recommended by the manufacturer and at a minimum frequency of at least one 

calibration per year. The Permittee must maintain calibration records for at least three years. 

D. Laboratory Accreditation 

All monitoring data required by Ecology must be prepared by a laboratory registered or 

accredited under the provisions of, Accreditation of Environmental Laboratories, Chapter 

173-50 WAC. Flow, ·temperature, settleable solids, pH, turbidity, and internal process 

control parameters are exempt from this requirement. Conductivity and pH must be 

accredited if the laboratory must otherwise be registered or accredited. Ecology exempts 

crops, soils, and hazardous waste data from this requirement pending accreditation of 

laboratories for analysis of these media. 

S3. REPORTING AND RECORDKEEPING REQUIREMENTS 

The Permittee must monitor and report in accordance with the following conditions. The 

falsification of information submitted to Ecology is a violation of the terms and conditions 

of this permit. 
Page 16 of 50

treatment and coritrol (and related appurtenances) which are installed to achieve compliance 
Page 19 of 50 

PermitNo. WA-000178-3 

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 only when the operation is necessary to achieve compliance with the 

conditions of this permit. 

A. Treatment System Operation Plan 

A Treatment System Operating Plan (TSOP) must be submitted to Ecology. This chapter 

must be entitled the "Treatment System Operating Plan." For the purposes of this NPDES 

permit, a 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 limitations of S 1. at the production levels used 

in developing these limitations. 

2. In the event of production rates which are below the baseline levels used to establish 

these limitations, the plan must describe the operating procedures and conditions 

needed to maintain design treatment efficiency. The monitoring and reporting must 

be described in the plan. 

3. In the event of an upset due to plant maintenance activities, severe storm water events, 

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

procedures and conditions employed to mitigate the upset. The monitoring and 

reporting must be described in the plan. 

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

facility which would affect the volume or character of the wastes discharged to the 

wastewater treatment system and a plan for monitoring and treating/controlling the 

discharge of maintenance-related materials (such as cleaners, degreasers, solvents, 

etc.). 

An updated Treatment System Operating Plan (TSOP) must be submitted to Ecology 

with the permit renew application. This plan must be updated and submitted, as 

necessary, to include requirements for any major modifications of the treatment system. 

B. Bypass Procedures 

Bypass, which is the intentional diversion of waste streams from any portion of a treatment 

facility, is prohibited, and Ecology may take enforcement action against a Permittee for 

bypass unless one of the following circumstances (1, 2, or 3) is applicable. 

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

Permit Limits or Conditions. 
Page 20 of 50 

Permit No. WA-000178-3 

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

potential to cause violations of limitations or other conditions ofthis 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 (10) days before the date 

of the bypass. 

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

Permit. This bypass is permitted only if: 

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. 

There are no feasible alternatives to the bypass, such as the. use of auxiliary 

treatment facilities, retention of untreated wastes, stopping production, 

maintenance during normal periods of equipment downtime (but not if 

adequate backup equipment should have been installed in the exercise of 

reasonable engineering judgment to prevent a bypass which occurred during 

normal periods of equipment downtime or preventative maintenance), or 

transport of untreated wastes to another treatment facility. 

Ecology is properly notified of the bypass as required in condition S3 .E of this 

permit. 

3. Bypass which is anticipated and has the Potential to Result in Noncompliance of this 

Permit. 

The Permittee must notify Ecology at least thirty (30) days before the planned date of 

bypass. The notice must contain (1) a description of the bypass and its cause; (2) an 

analysis of all known alternatives which would eliminate, reduce, or mitigate the need 

for bypassing; (3) a cost-effectiveness analysis of alternatives including comparative 

resource damage assessment; (4) the minimum and maximum duration of bypass under 

each alternative; ( 5) a recommendation as to the preferred alternative for conducting the 

bypass; (6) the projected date of bypass initiation; (7) a statement of compliance with 

SEP A; (8) a request for modification of water quality standards as provided for in 

WAC 173-201A-110, if an exceedance of any water quality standard is anticipated; and 

(9) steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. 

For probable construction bypasses, the need to bypass is to be identified as early in 

the planning process as possible. The analysis required above must be considered 

during preparation of the engineering report or facilities plan and plans and 

specifications and must be included to the extent practical. In cases where the 

probable need to bypass is determined early, continued analysis is necessary up to and 

including the construction period in an effort to minimize or eliminate the bypass. 
Page 21 of 50 

·Permit No. WA-000178-3 

Ecology will consider the following prior to issuing an administrative order for this 

type ofbypass: 

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

activities essential to meet the requirements of this permit. 

b. If there are feasible alternatives to bypass, 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. 

c. If the bypass is planned and scheduled 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. The public must be 

notified and given an opportunity to comment on bypass incidents of significant 

duration, to the extent feasible. Approval of a request to bypass will be by 

administrative order issued by Ecology 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..

those work practices developed through pollution prevention activities from previous 

permit P2 plans, stormwater pollution prevention plans (SWPPP), solid waste control 

plans, and spill plans. 
Page 27 of 50 

Permit No. WA-000178-3 

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. These procedures and other measures/facilities currently employed at the

treatment system, to storm water, and/or to waters of the state must be continued or 

maintained unless modified by the pollution prevention plan updates required below. 

Solid Waste 

The Permittee must handle and dispose of all solid waste material in such a manner as to 

prevent its entry into state ground water 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 of the 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 water or surface waters. 

Storage Tank Wastewater 

The operation of removing wastewater from oil, product, and intermediate distillate 

storage tanks must be performed in a manner and with facilities as required to prevent the 

wastewater from draining or spilling onto the ground. 

A. Pollution Prevention Plan Development and Implementation 

The Permittee must prepare an update to its Pollution Prevention Plan to meet the 

objectives identified below, and must submit the updated plan to the Department for 

review and approval by November 1, 2008. The Permittee must implement the approved 

pollution prevention plan update and any approved modifications to the plan- and must 

abide by the time frames identified - throughout the term 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 its current 

Pollution Prevention Plan, and those identified in Ecology Publi.cation 02-07-017 (Water 

Pollution Prevention Opportunities 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. 

B. Specific Plan Update Requirements 

The Permittee must update the following plan elements as necessary: 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 A includes references to guidance documents, specific items to be included in 

the plan, and procedures for identifying, evaluating, and prioritizing pollution prevention 
. Page 28 of 50 

Permit No. WA-000178-3 

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 in the plan submittal, a schedule for completing 

the analysis. The biennial report must provide a schedule for evaluation of further 

opportunities, and then the timeframe for implementing any selected. 

C. Storm water Inspections 

The Permittee must conduct two storm water inspections per year; one during the wet 

season (October 1 through April30) and the other during the dry season (May 1 through 

September 30). 

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

include and record observations of the presence of any floating materials, suspended 

solids, oil and grease, discolorations, turbidity, odor, etc. -in storm water runoff from 

throughout the refinery-that could contribute to a discharge off-site. 

The Permittee's dry season inspection must determine the presence of any unpermitted 

non-storm water discharges-such as sanitary wastewater, non-contact cooling water, 

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

water drainage system. If an unpermitted, non-storm water discharge is discovered, the 

Permittee must immediately notify the Department. 

Inspections must be conducted by staffknowledgeable about, and trained in the 

application of, BMPs and pollution prevention activities at the refinery. 

D. Plan Evaluation and Biennial Reporting 

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

prevention plan and associated existing SOPs, BMPs and work practices. The Permittee 

must ensure that they are updated or otherwise modified to reflect current conditions; 

ensure that measures in the plan, selected to reduce or eliminate pollutant loadings are 

both adequate to the task; and properly implemented (in accordance with the terms of the 

permit); and that such evaluation must enable the Permittee to determine whether any 

additional controls are needed. 

The Permittee must modify the pollution prevention plan whenever a change in design, 

construction, operation, or maintenance of the facility, significantly increases the 

generation or potential to generate water pollutants; or when such change causes the 

pollution prevention plan and associated existing SOPs, BMPs and work practices to less 

effectively control pollutants. The Permittee must implement any modifications to the 

pollution prevention plan in a timely manner. 
Page 29 of 50 

Permit No. WA-000178-3 

The Permittee must submit a biennial progress report every two years thereafter (starting 

November 15

\ 2008) including submitting the Pollution Prevention Plan Update as 

required by Permit ConditionS 11.B. 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, Ecology 

encourages the Permittee to employ continuous improvement principles-including the 

systematic and ongoing identification, evaluation, and implementation of pollution

The permittee is authorized to treat dangerous wastes, generated on- or off-site, at the 

wastewater treatment facility under ·Chapter WAC 173-303-802(5)-the "permit by rule" 

provisions. This authorization is limited to the on-site waste streams identified on the 

permit application and application amendments as approved by Ecology. 

S13. CONSTRUCTION STORMW ATER 

Construction stormwater includes stormwater associated with construction activity and 

construction support activities at the construction site (equipment staging yards, material 

storage areas, borrow areas, etc.). 

A. Authorization and Conditions to Discharge Construction Stormwater 

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

Permittee is authorized to discharge construction stormwater at Outfalls OOlB, 002, 003, 

004, 005, and 006 subject to the following requirements and limitations: 

a. Construction stormwater discharges must not cause or contribute to a violation of 

surface water quality standards (Chapter 173-201A WAC), ground water quality 

standards (Chapter 173-200 WAC), sediment management standards (Chapter 

173-204 WAC), and human health-based criteria in the National Toxics Rule (40 

CFR Part 131.36). Discharges that do not comply with these standards are not 

authorized. 

b. Prior to the discharge of construction stormwater to waters of the state, the 

Permittee must apply all known, available, and reasonable methods of prevention, 

control, and treatment (AKAR1). This includes the preparation and 

implementation of an adequate Stormwater Pollution Prevention Plan (SWPPP), 

with all appropriate best management practices (BMPs) installed and maintained 

in accordance with the SWPPP and the terms and conditions of this permit. 
Page 30 of 50 

PermitNo. WA-000178-3 

c. Ecology presumes the Permittee's construction stormwater management complies 

with water quality standards, unless discharge monitoring data or other sitespecific information demonstrate that a discharge causes or contributes to a 

violation of water quality standards, when the Permittee is: 

e In full compliance with all permit conditions -including planning, sampling, 

monitoring, reporting, and recordkeeping conditions. 

e Fully implementing construction stormwater BMPs contained in stormwater 

management manuals published or approved by Ecology, or construction 

stmmwater BMPs that are demonstrably equivalent to BMPs contained in 

stormwater technical manuals published or approved by Ecology-including 

the proper selection, implementation, and maintenance of all applicable and 

appropriate BMPs for on-site pollWion control. 

B. Construction Stormwater Pollution Prevention Plans 

A standard Stormwater Pollution Prevention Plan (SWPPP) for construction activities 

greater than one acre and less than five (1-5) acres, including construction dewatering, 

must be prepared and submitted to the Department by November 30, 2008. Project 

details for each construction project and for any site-specific issues for that project that 

require additional BMPs must be submitted to the Department at least 90 days prior to 

the start of construction. 

The Permittee must prepare and implement a Stormwater Pollution Prevention Plan 

(SWPPP) for construction activity occurring on sites greater than 5 acres- including 

construction dewatering -prior to the start of each construction project. The Permittee 

must submit all details for each construction project to the Department at least 90 days 

prior to the start of construction. 

Each SWPPP must be prepared in accordance with the objectives and requirements 

identified in Special Condition S.9. of the National Pollutant Discharge Elimination 

System and State Waste Discharge Construction Stormwater General Permit issued by 

Ecology on November 16, 2005, or as revised (Ecology Construction Stormwater 

General Permit). 

C. Monitoring Requirements 

The Permittee must sample the discharge from construction sites > 1 acre that discharge 

directly off site at least once every calendar week, when there is a discharge of 

stormwater from the site. Samples must be representative of the flow and characteristics 

of the discharge. 

When there is no discharge during a calendar week, sampling is not required. Sampling 

is not required outside of normal working hours or during unsafe conditions. If a 

Permittee is unable to sample during a monitoring period, the Discharge Monitoring 

Report (DMR) must include a brief explanation. 
Page 31 of 50 

Permit No. WA-000178-3 

Sampling is required at all discharge points where stormwater is discharged off-site. All 

sampling point(s) must be identified on the SWPPP site map and must be clearly marked 

in the field with a flag, tape, stake or other visible marker. 

Soil disturbance area is calculated by adding together all areas affected by construction 

activity. "Construction activity" means clearing, grading, excavation, and any other 

activity which disturbs the surface of the land, including ingress/egress from the site. 

The primary monitoring requirements for projects that discharge off site are 

summarized below: 

Summary of Monitoring Requirements 

Soil Disturbance Weekly Site Weekly Turbidity Weekly pH 

Area Inspections Sampling Sampling 

Sites <1 acre Required Not Required Not required unless construction 

activity involves significant 

concrete work or the use of 

engineered soils 

Sites > 1 acre Required Required Required 

D. Turbidity Monitoring 

Turbidity (analysis must be performed with a calibrated turbidity meter (turbidimeter), 

either on-site or at an accredited lab. The results must be recorded in the site log book in 

Nephelometric Turbidity Units (NTU). 

"" "" Units Analytical Method ' Sampling " "• Parameter 

""·· 

"" "" "Frequency

EPA180.1 discharging 

The Benchmark Value for turbidity is 25 NTU. If the discharge turbidity is greater than 

25 NTU, the CESCL (Certified Erosion and Sediment Control Lead) must: 

., Review the SWPPP for compliance with requirements identified in Special 

Condition S.8. of the Ecology Construction Stormwater General Permit, and make 

appropriate revisions within 7 days of the discharge that exceeded the benchmark. 

e Fully implement and maintain appropriate construction stormwater source control 

and/or treatment BMPs as soon as possible, but within 10 days of the discharge 

that exceeded the benchmark. If additional time is needed for a source control or 

treatment project, the permittee must submit (within 10 days of the discharge that 

exceeded the benchmark) a description of the project and an implementation 

schedule for Ecology's review and approval. 
Page 32 of 50 · 

Permit No. WA-000178-3 

• Document construction stormwater BMP implementation and maintenance in the 

site log book. 

If the discharge turbidity is greater than or equal to 250 NTU; then CESCL must also: 

• Notify Ecology by phone in accordance with Condition S3 .E. 

• Continue to sample discharges daily until either the turbidity resolves to 25 NTU 

(or lower); or the CESCL demonstrates compliance with the water quality 

standard for turbidity- no more than 5 NTU over background turbidity, if 

background is less than 50 NTU; or no more than 10% over background turbidity, 

if background is 50 NTU or greater- or the discharge stops or is eliminated, or is 

diverted to the refinery's wastewater treatment plant. 

E. pH Monitoring 

For sites greater than one acre, and where construction activity involves significant 

concrete work or the use of engineered soils, the Permittee must obtain a representative 

sample of construction stormwater at least once per week and conduct pH analysis. For 

sites less than one acre, pH analysis is required once per week when there is active 

concrete work in progress, or when engineered soils are in use. The Permittee must 

perform pH analysis on-site with a calibrated pH meter, pH test kit, or wide range pH 

indicator paper. The Permittee must record pH monitoring results in the site log book 

The benchmark value for pH is 8.5 standard units. Any time sampling indicates that 

pH is 8.5 or greater, the Permittee must prevent the high pH water (8.5 or above) from 

entering storm sewer systems or surface waters; and if necessary, the Permittee must 

adjust or neutralize the high pH water, using an appropriate treatment BMP. The 

Permittee must obtain written approval from Ecology prior to using any form of chemical 

treatment other than C02 sparging or dry ice. 

F. Site Log Book 

The Permittee must maintain a site log book that contains a record of implementation of 

its SWPPP and other permit requirements including the installation and maintenance of 

construction stormwater BMPs, site inspections, and stormwater monitoring. 

G. Site Inspections 

Site inspections must include all areas disturbed by construction activities, all 

construction stormwater BMPs, and all stormwater discharge points. Stormwater must be 

visually examined for the presence of suspended sediment, turbidity, discoloration, and 

oil sheen. Inspectors must evaluate the effectiveness of BMPs and determine if it is 

necessary to install, maintain, or repair BMPs to improve the quality of stormwater 

discharges. 
Page 33 of 50 

PermitNo. WA-000178-3 

Based on the results of the inspection, the Permittee must correct the problems identified 

as follows: 

• Review the SWPPP for compliance with Condition S8 of the Ecology 

Construction Stormwater General Permit and make appropriate revisions within 7 

days of the inspection; and 

o Fully implement and maintain appropriate construction stormwater source control 

and/or treatment BiVJPs as soon as possible, but no later than 10 days of the 

inspection; and 

o Document construction stormwater BMP implementation and maintenance in the 

site log book. 

The site inspections must be conducted at least once every calendar week and within 24 

hours of any discharge from the site. The inspection frequency for temporarily stabilized, 

inactive sites may be reduced to once every calendar month. 

Site inspections must be conducted by a person who is knowledgeable in the principles 

and practices of erosion and sediment control. The inspector must have the skills to: 

• Assess the site conditions and construction activities that could impact the quality 

of stormwater, and 

• Assess the effectiveness of erosion and sediment control measures used to control 

the quality of storm water discharges. 

Construction sites one acre or larger that discharge storm water to surface waters of the 

state, must have site inspections conducted by a CESCL. The CESCL must be identified 

in the SWPPP and must be present on~site or on-call at all times. Certification must be 

obtained through an approved erosion and sediment control training program that meets 

the minimum training standards established by Ecology (see 

http:/ /www.ecy. wa. gov/programs/wq/stormwater/ cescl.htm or the Storm water 

Management Manual for Western Washington, dated February 2005). 

The inspector must sum1narize the results of each inspection in an inspection report or . 

checklist and be entered into, or attached to, the site log book. At a minimum, each 

inspection report or checklist must include: 

• Inspection date and time. 

o Weather information; general conditions during inspection and approximate 

amount of precipitation since the last inspection, and within the last 24 hours. 

e A summary or list of all construction stormwater BMPs which have been 

implemented, including observations of all erosion/sediment control structures or 

practices. 

• The following must be noted: locations of construction stormwater construction 

stormwater BMPs inspected, locations of construction stormwater BMPs that 

need maintenance, the reason maintenance is needed, locations of construction 
Page 34 of 50 

Permit No. WA-000178-3 

stormwater BMPs that failed to operate as designed or intended, and locations 

where additional or different construction stormwater BMPs are needed, and the 

reason(s) why. 

• A description of storm water discharged from the construction site. The inspector 

must note the presence of suspended sediment, turbid water, discoloration, and/or 

oil sheen, as applicable. 

• ·Any water quality monitoring performed during the inspection. 

• General comments and notes, including a brief description of any construction 

storm water BMP repairs, maintenance, or installations made as a result of the 

inspection. 

o A statement that, in the judgment of the person conducting the site inspection, the 

site is either in compliance or out of compliance with the terms and conditions of 

the construction SWPPP and the permit. If the site inspection indicates that the 

site is out of compliance, the inspection report must include a summary of the 

remedial actions required to bri:ri.g the site back into compliance, as well as a 

schedule of implementation. 

• Name, title, and signature of the person conducting site inspection; and the 

following statement: "I certify that this report is true, accurate, and complete, to 

the best of my knowledge and belief'.

GlS. UPSET 

Definition- "Upset" means an exceptional incident in which there is unintentional and 

temporary noncompliance with technology-based pennit 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 proceedings the Permittee seeking to establish the occurrence of an 

upset has the burden of proof. 

G16. PROPERTY RIGHTS 

This permit does not convey any property rights of any sort, or any exclusive privilege. 

G17. DUTY TO COMPLY 

The Permittee must comply with all conditions of this permit. Any permit noncompliance 

constitutes a violation of the Clean Water Act and is grounds for enforcement action;·for 

permit termination, revocation and reissuance, or modification; or denial of a permit renewal 

application. 

G18. TOXIC POLLUTANTS 

The Permittee must comply with effluent standards or prohibitions established under Section 

307(a) of the Clean Water Act for toxic pollutants within the time provided in the 

regulations that establish those standards or prohibitions, even if this permit has not yet been 

modified to incorporate the requirement. 

G19.PENALTIES FOR TAMPERING 

The Clean Water Act provides that any person who falsifies, tampers with, or knowingly 

renders inaccurate any monitoring device or method required to be maintained under this 

permit will, upon conviction, be punished by a fine of not more than $10,000 per violation, 

or by imprisonment for not more than two years per violation, or by both. If a conviction of 

a person is for a violation committed after a first conviction of such person under this 
Page 41 of 50

Condition, punishment will be a fine of not more than $20,000 per day of violation, or by 

imprisonment of not more than four ( 4) years, or by both. 

G20. REPORTING ANTICIPATED NON-COMPLIANCE 

The Pe1mittee must give advance notice to Ecology by submission of a new application or 

supplement thereto at least 12 months prior to commencement of such discharges, of any 

facility expansions, production increases, or other planned changes, such as process 

modifications, in the permitted facility or activity which may result in noncompliance with 

permit limits or conditions. Any maintenance of facilities, which might necessitate 

unavoidable interruption of operation and degradation of effluent quality, must be scheduled 

during non-critical water quality periods and carried out in a manner approved by Ecology. 

G21. REPORTING OTHER INFORtVIATION 

Where the Permittee becomes aware that it failed to submit any relevant facts in a permit 

application, or submitted incorrect information in a permit application or in any report to 

Ecology, such facts or information must be submitted promptly. 

G22. REPORTING REQUIREMENTS APPLICABLE TO EXISTING

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 44 of 50 

PermitNo. WA-000178-3 

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. Influent 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 ~vash 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 otherwise 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 ofthe amount of pollutants reduced, and the environmental or 

other benefits that will be achieved. The Permittee is not required to analyze the substitution of 

alternate crude oil/feedstock supplies as a pollution prevention opportunity. 

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. 
Page 45 of 50 

Permit No. WA-000178-3 

In identifying and evaluating pollution prevention opportunities, the Permittee must consider the 

following: 

o All reasonably expected activities and conditions, such as nonnal operations, 

maintenance, and other ancillary activities; equipment failure; improper operation; 

upsets, accidents, spills, leaks; and natural events such as rainfall, snowfall, etc. 

o All areas of the refinery with potential to generate water pollutants 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. 

The following are examples of pollution prevention strategies that may warrant Permittee's 

evaluation: 

o 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 

o 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 

• Alternative 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 

refinery 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 
Page 46 of 50 

Permit No. WA-000178-3 

source, second to those that recycle or reuse the pollutants, and third to those that provide atsource 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.
