S4. C. Duty to mitigate

The Permittee must 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.Page 15 of 40
Permit No. WA0022772

S4. D. Notification of new or altered sources

1. The Permittee must submit writt en notice to Ecology whenever any new discharge or a substantial change in volume or character of an existing discharge into the wastewater treatment plant is proposed which:

a. Would interfere with the operation of, or exceed the design capacity of,
any port ion of the wastewater treatment plant

.
b. Is not part of an approved general sewer plan or approved plans and specifications

.

c. Is subject to pretreatment standards under 40 CFR Part 403 and Section 307(b) of the Clean Water Act.

2. This notice must include an e valuation of the wastewater treatment plant’s ability to adequately transport and treat the added flow and/or waste load, the quality and volume of effluent to be discharged to the treatment plant , and the anticipated impact on the Permittee’s effluent [40 CFR 122.42(b)].

S4. E. Infiltration and inflow evaluation

E xcessive collection system inflow and infiltration was confirmed by data submitted to Ecology in an October 2011 I/I Evaluation R eport

. The Permittee

must therefore submit to Ecology a n annual report summarizing progress made in implementing I/I corrective measures

. The intent of the annual I/I report is to provide a brief update on the status of projects intended to reduce I/I . The report must present an updated schedule for projects, identify completed projects, and identify changes in project priority if they were prioritized differently in the most recent Comprehensive Sewer Plan . The Permittee must submit the report by
December 3 1, 2013 , and annually thereafter

.

S5. Operation and maintenan ce
The Permittee must at all times properly operate and maintain all facilities and 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 also includes keeping a daily operation logbook (paper or electronic), adequate laboratory controls, and appropriate quality assurance procedures. This provision of the permit requires the Permittee to operate backup or auxiliary facilities or similar systems only when the operation is necessary to achieve compliance with the conditions of this permit.

S5. A. Certified operator

This permitted facility must be operated by an operator certified by the state of Washington for at least a Class 3 plant. This operator must be in responsible charge of the day

- to

- day operation of the wastewater treatment plant. An operator
certified for at least a Class 2 plant must be in charge during all regularly
scheduled shifts.Page 16 of 40
Permit No. WA0022772

S5. B. O peration and maintenance program

The Permittee must:

1. Institute an adequate operation and maintenance program for the entire
sewage system.

2. Keep maintenance records on all major electrical and mechanical components of the treatment plant, as well as the sewage system and pumping stations. Such records must clearly specify the frequency and type of maintenance recommended by the manufacturer a nd must show the frequency and type of maintenance performed.

3. Make maintenance records available for inspection at all times.

S5.C. S hort

- term reduction

The Permittee must schedule any facility maintenance, which might require interruption of wastewater treatment and degra de effluent quality, during

non

- critical water quality periods and carry this maintenance out in a manner approved by Ecology.

If a Permittee contemplates a reduction in the level of treatment that would cause a violation of permit disc harge limits on a short

- term basis for any reason, and such reduction cannot be avoided, the Permittee must:

1. Give written notification to Ecology, if possible, thirty (30) days prior to such
activities.

2. Detail the reasons for, length of time of, and the potential effects of the
reduced level of treatment.

This notification does not relieve the Permittee of its obligations under this permit.

S5. D. Electrical power failure

The Permittee must ensure that adequate safeguards prevent the discharge of

untreat ed wastes or wastes not treated in accordance with the requirements of this permit during electrical power failure at the treatment plant and/or sewage lift stations. Adequate safeguards include, but are not limited to

, alternate power sources, standby ge nerator(s), or retention of inadequately treated wastes.

The Permittee must maintain Reliability Class II (EPA 430/9

- 74

- 001) at the wastewater treatment plant

. Reliability Class II requires a backup power source sufficient to operate all vital components and critical lighting and ventilation during peak wastewater flow conditions. Vital components used to support the secondary processes (i.e., mechanical aerato rs or aeration basin air compressors) need not be operable to full levels of treatment, but must be sufficient to maintain
the biota.Page 17 of 40
Permit No. WA0022772

S5. E. Prevent connection of inflow

The Permittee must strictly enforce its sewer ordinances and not allow the
connection o f inflow (roof drains, foundation drains, etc.) to the sanitary sewer
system.

S5. F. 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 enforcemen t action against a Permittee for a bypass unless one of the following circumstances (1, 2, or 3) applies.

1. B ypass for essential maintenance without the potential to cause violation of permit limits or conditions

. This permit authorizes a b ypass if it allow s 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 possib le, at least ten (10) days before the date of the bypass.

2. B ypass which is unavoidable, unanticipated, and results in noncompliance of this permit

.
This permit authorizes such a bypass 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.

• 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.

c. Ecology is properly notified of the bypass as required in Special C ondition

S3

. E of this permit.Page 18 of 40
Permit No. WA0022772

3. If bypass is anticipated and has the potential to resu lt 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 eli minate, 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 al ternative 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 b ypass:

• 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 untrea ted 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 e nvironment.Page 19 of 40
Permit No. WA0022772

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, t o the extent feasible. Ecology will approve a request to bypass by issuing an administrative order under RCW 90.48.120.

S5. G. O perations and M aintenance ( O&M) M anual

The Permittee must keep the approved Operations and Maintenance Manual
available at the treatment plant and all operators must follow the instructions and procedures of this manual. Whenever the Permittee makes substantial changes or updates to the O&M Manual, the Permittee must submit the changes to Ecology for review and approval.

### General Conditions

G1. Signatory requirements

1. All applications, reports, or information submitted to Ecology must be signed and
certified.

a. In t he case of corporations, by a responsible corporate officer. For the purpose of this section, a responsible corporate officer means:

• A president, secretary, treasurer, or vice

- president of the corporation in charge of a principal business function, or an y other person who performs similar policy or decision making functions for the corporation, or

• The manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions which govern th e operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiating and directing other comprehensive measures to assure long

- term environmental compliance with environment al laws and regulations; the manager can ensure that the necessary systems are established or actions taken to gather complete and accurate information for permit application requirements; and where authority to sign documents has been assigned or delegate d to the manager in accordance with corporate procedures.

• In the case of a partnership, by a general partner.

• In the case of sole proprietorship, by the proprietor.

• In the case of a municipal, state, or other public facility, by either a principal
executi ve officer or ranking elected official.

Applications for permits for domestic wastewater facilities that are either owned or operated by, or under contract to, a public entity shall be submitted by the public entity.

2. All reports required by this permit and other information requested by Ecology must be signed by a person described above or by a duly authorized representative of that person. A person is a duly authorized representative only if:

c. A material change in quantity or type of waste disposal.Page 28 of 40
Permit No. WA0022772

d. A determination that the permitted activity endangers human health or the environment, or contributes to water quality standards violations and can only be regulated to acceptable levels by permit modification or termination.

e. A change in any condition that requires either a temporary or permanent reduction, or elimination of any discharge or sludge use or disposal practic e controlled by the permit.

f. Nonpayment of fees assessed pursuant to RCW 90.48.465.

g. Failure or refusal of the Permittee to allow entry as required in RCW 90.48.090.

2. The following are causes for modification but not revocation and reissuance except
when the Permittee requests or agrees:

a. A material change in the condition of the waters of the state.

b. New information not available at the time of permit issuance that would have justified the application of different permit conditions.

c. Material and substantial alt erations or additions to the permitted facility or activities which occurred after this permit issuance.

d. Promulgation of new or amended standards or regulations having a direct bearing upon permit conditions, or requiring permit revision.

e. The Permittee has requested a modification based on other rationale meeting the
criteria of 40 CFR Part 122.62.

f. Ecology has determined that good cause exists for modification of a compliance schedule, and the modification will not violate statutory deadlines.

g. Incorporation of an approved local pretreatment program into a municipality’s permit.

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

a. When cause exists for ter mination for reasons listed in 1 .a through 1. g of this section, and Ecology determines that modification or revocation and reissuance is appropriate.

b. When Ecology has received notification of a proposed transfer of the permit. A permit may also be modified to reflect a transfer after the effective da te of an automatic transfer ( General Condition G 7 ) 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 lat er than one hundred eighty (180) 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. T he permitted facility b eing 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 o f pollutants discharged.Page 29 of 40
Permit No. WA0022772

3. A significant change in the Permittee’s sludge use or disposal practices. Following such notice, and th e submittal of a new application or supplement to the existing application, along with required engineering plans and reports, this permit may be modified, or revoked and reissued pursuant to 40 CFR 122.62(a) to specify and limit any pollutants not previou sly 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.

G5. 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 f or approval in
accordance with C hapter 173

- 240 WAC. Engineering reports, plans, and specifications must be submitted at least one hundred eighty (180) days prior to the planned start of construction unless a shorter time is approved by Ecology. Facilities must be constructed and operated in accordance with the approved plans.

G6. Compliance w ith other laws a nd statutes

G10. Duty t o provide information

The Permittee must submit to Ecology, within a reasonable time, all information which Ecology may request to determine whether cause exists for modifying, revoking and reissuing, or terminating this permit or to determine compliance with this permit. The
Permittee must also submit to Ecology upon request, copies of records required to be kept by this permit.

G11. Other requirement s o f 40 C FR

All other requirements of 40 CFR 122.41 and 122.42 are incorporated in this permit by
reference.

G12. Additional monitoring

Ecolo gy may establish specific monitoring requirements in addition to those contained in this permit by administrative order or permit modification.

G13. Payment o f fees

The Permittee must submit payment of fees associated with this permit as assessed by Ecolog y.

G14. Penalties f or violating permit conditions

Any person who is found guilty of willfully violating the terms and conditions of this permit is deemed guilty of a crime, and upon conviction thereof shall be punished by a fine of up to ten thousand dolla rs ($10,000) and costs of prosecution, or by imprisonment in the discretion of the court. Each day upon which a willful violation occurs may be deemed a separate and additional violation.

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 suc h 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.Page 31 of 40
Permit No. WA0022772

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
fa cilities, 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 requir ements 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. A n upset occurred and that the Per mittee can identify the cause(s) of the upset

.
2. T he permitted facility was being properly operated at the time of the upset

.
3. T he Permittee submitted notice of the upset as required in Special Condition S3.E

.
4. T he Permittee complied with any remedial measures required under S3.E of this permit.

In any enforcement action the Permittee seeking to establish the occurrence of an upset has the burden of proof.

G16. Property rights

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

G17. Duty t o 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 p ollutants 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 f or tampering

The Clean Water Act provides that any person wh o falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required to be maintained under this permit shall , upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more tha n two (2) years per violation, or by both.Page 32 of 40
Permit No. WA0022772

If a conviction of a person is for a violation committed after a first conviction of such person under this condition, punishment shall 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. 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 th an fourteen (14) days following each schedule date.

G21. Service agreement review

The Permittee must submit to Ecology any proposed service agreements and proposed revisions or updates to existing agreements for the operation of any wastewater treatment
fa cility covered by this permit. The review is to ensure consistency with C hapters 90.46
and 90.48 RCW as required by RCW 70.150.040(9) . In the event t hat Ecology does not comment within a thirty

- day (30) period, the Permittee may assume consistency and proceed with the service agreement or the revised/updated service agreement

### Appendix A

**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 and applicat ion required monitoring unless:

• Another permit condition specifies other methods, detection levels, or quantitation levels

.

• 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 rep ort or in the required report.

If the Permittee is unable to obtain the required DL and QL in its efflue nt due to matrix effects, the Permittee
must submit a matrix

- specific detection limit (MDL) and a quantitation limit (QL) to Ecology with appropriate laboratory documentation.

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 Quali ty 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.

Eco logy added this appendix to the permit in order to reduce the number of ana lytical “non

- detects” 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 determined by the procedure given in 40 CFR part 136, Appendix B.

2. Quantitation Level (QL) also known as Minimum Level of Quantitation (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 th e 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 10 n

, whe re 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
Adviso ry Committee on Detection and Quantitation Approaches and Uses in Clean Water Act Programs Submitted to the US Environmental Protection Agency December 2007).
