a Average monthly effluent limit means the highest allowable average of daily discharges over a calendar 

month. To calculate the discharge value to compare to the limit, you add the value of each daily discharge 

measured during a calendar month and divide this sum by the total number of daily discharges measured.

b Maximum daily effluent limit 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. This does not 

apply to pH.

c The Department of Ecology (Ecology) uses the flow data submitted in the application to set permit fees. The 

Permittee must report to Ecology when actual flows exceed the values reported on the permit application.

d

Indicates the range of permitted values. Do not average pH values. 

e The sampling point for Outfall 001 shall be in the parshall flume where the discharge of the treatment ponds 

drops in to Hanaford Creek, unless the limit is stated as an increase over background.

f Currently, these limits do not apply on discharges to Pond 3E. When pond 3E is reclaimed and becomes the 

water of the state then these limits will be effective immediately.

g Ecology will use the quantitaion level (QL) of Appendix A of the permit as the compliance evaluation for 

Total Residual Chlorine.

measurement, the daily discharge is the average measurement of the pollutant over the day. This does not 

apply to pH.

c Effluent samples for BOD5 analysis may be taken before or after the disinfection process. If taken after, 

dechlorinate and reseed the sample.

d The sampling point for TSS shall be just before the effluent enters the Oxidation Pond, at the V-Notch Weir 

in the clarifier section of the sewage treatment plant

e To calculate the average monthly and average weekly values for fecal coliforms you must use the geometric 

mean. Ecology gives directions to calculate this value in publication No. 04-10-020, Information Manual for 

Treatment Plant Operators available at: http://www.ecy.wa.gov/pubs/0410020.pdf

f

Final Effluent means wastewater which is exiting, or has exited, the last treatment process or operation. 

Typically, this is after or at the exit from the chlorine contact chamber or other disinfection process.

Temperature grab sampling must occur when the effluent is at or near its daily maximum temperature, 

which is usually in the later afternoon. If temperature is measured continuously, the Permittee must 

determine and report a daily maximum from half-hour measurements in a 24-hour period. To determine 

the daily average, use the temperature on the half-hour from the chart for the 24-hour period and calculate 

the average of the values. Continuous monitoring instruments must achieve an accuracy of 0.2 degrees C 

and the Permittee must verify accuracy annually.

1The sampling point for discharge to Pond 3E is at the north effluent pond pump discharge.

The Permittee must summarize the following information in the initial chapter of the 

O&M Manual entitled the “Treatment System Operating Plan.” 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 of S1 at the production levels used in 

developing these limits.

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

establish these limits, 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 stormwater 

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.).
Page 15 of 38

Permit No. WA0001546 

The Permittee must submit an updated Treatment System Operating Plan to Ecology with 

the application for renewal. This plan must be updated and submitted, as necessary, to 

include requirements for any major modifications of the 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 limits 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 days before the 

date of the bypass.

2. Bypass which 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.

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. 

Transport of untreated wastes to another treatment facility or 

preventative maintenance), or transport of untreated wastes to another 

treatment facility.

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.
Page 16 of 38

Permit No. WA0001546 

a. The Permittee must notify Ecology at least 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 SEPA. 

A request for modification of water quality standards as provided 

for in WAC 173-201A-410, 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.

If the Permittee planned and scheduled the bypass to minimize 

adverse effects on the public and the environment.
Page 17 of 38

Permit No. WA0001546 

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.

deemed guilty of a crime, and upon conviction thereof will be punished by a fine of up to $10,000 

and costs of prosecution, or by imprisonment in the discretion of the court. Each day upon which 

a willful violation occurs is a separate and additional violation. 

Any person who violates the terms and conditions of a waste discharge permit must incur, in 

addition to any other penalty as provided by law, a civil penalty in the amount of up to $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 limits because of factors beyond the 

reasonable control of the Permittee. An upset does not include noncompliance to the extent 

caused by operational error, improperly designed treatment facilities, inadequate treatment 

facilities, lack of preventive maintenance, or careless or improper operation.

An upset constitutes an affirmative defense to an action brought for noncompliance with such 

technology-based permit effluent limits if the requirements of the following paragraph are met.

A Permittee who wishes to establish the affirmative defense of upset must demonstrate, through 

properly signed, contemporaneous operating logs or other relevant evidence that: (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 
Page 28 of 38

Permit No. WA0001546 

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 Condition, punishment 

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

four years, or by both.

G20. REPORTING REQUIREMENTS APPLICABLE TO EXISTING MANUFACTURING,

COMMERCIAL, MINING, AND SILVICULTURAL DISCHARGERS

The Permittee belonging to the categories of existing manufacturing, commercial, mining, or 

silviculture must notify Ecology as soon as they know or have reason to believe:

A. That any activity has occurred or will occur which would result in the discharge, on a 

routine or frequent basis, of any toxic pollutant which is not limited in this permit, if that

discharge will exceed the highest of the following “notification levels:”

1. One hundred micrograms per liter (100 g/L).

2. Two hundred micrograms per liter (200 g/L) for acrolein and acrylonitrile; five 

hundred micrograms per liter (500 g/L) for 2,4-dinitrophenol and for 2-methyl4,6-dinitrophenol; and one milligram per liter (1 mg/L) for antimony.

3. Five times the maximum concentration value reported for that pollutant in the 

permit application in accordance with 40 CFR 122.21(g)(7).

4. The level established by the Director in accordance with 40 CFR 122.44(f).

Permit No. WA0001546 

B. That any activity has occurred or will occur which would result in any discharge, on a 

non-routine or infrequent basis, of a toxic pollutant which is not limited in this permit, if 

that discharge will exceed the highest of the following “notification levels:”

1. Five hundred micrograms per liter (500 g/L).

2. One milligram per liter (1 mg/L) for antimony.

3. Ten times the maximum concentration value reported for that pollutant in the permit 

application in accordance with 40 CFR 122.21(g)(7).

4. The level established by the Director in accordance with 40 CFR 122.44(f).

G21. COMPLIANCE SCHEDULES

Reports of compliance or noncompliance with, or any progress reports on, interim and final 

requirements contained in any compliance schedule of this permit must be submitted no later than 

14 days following each schedule date.

APPENDIX A 

EFFLUENT CHARACTERIZATION FOR POLLUTANTS

THIS LIST INCLUDES EPA REQUIRED POLLUTANTS (PRIORITY POLLUTANTS) AND 

SOME ECOLOGY PRIORITY TOXIC CHEMICALS (PBTs)

The following table specifies analytical methods and levels to be used for effluent characterization in 

NPDES and State waste discharge permits. This appendix specifies effluent characterization 

requirements of the Department of Ecology unless other methods are specified in the body of this permit. 

This permit specifies the compounds and groups of compounds to be analyzed. Ecology may require 

additional pollutants to be analyzed within a group. The objective of this appendix is to reduce the 

number of analytical “non-detects” in permit-required monitoring and to measure effluent concentrations 

near or below criteria values where possible at a reasonable cost. If a Permittee knows that an alternate, 

less sensitive method (higher DL and QL) from 40 CFR Part 136 is sufficient to produce measurable 

results in their effluent, that method may be used for analysis.

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 determined by the procedure given in 40 CFR part 136, 

Appendix B.

2. Quantitation Level (QL) is equivalent to EPA’s Minimum Level (ML) which is defined in 40 

CFR Part 136 as the minimum level at which the entire GC/MS system must give recognizable 

mass spectra (background corrected) and acceptable calibration points. These levels were 

published as proposed in the Federal Register on March 28, 1997
