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

measureme nt, 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 w hen actual flows exceed the values reported on the permit application.

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

e 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.

f 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.

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

1. Bypass for Essential Maintenance without the Potential t o 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 E cology prior to the bypass. The Permittee must submit prior notice, if possible, at lea st ten days before the date of the bypass.

2. Bypass w hich is Unavoidable, Unanticipated, and Results in Noncompliance of this Permit.

This bypass is permitted only if:

By pass 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 t o 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 potentia l 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 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 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 ex ceedance 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 earl y 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 tr eatment 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, t o the extent feasible. Ecology will approve a request to bypass by issuing an administrative order under RCW 90.48.120.

An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment f acilities, 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 paragrap h 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 thePage 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 o f 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 deni al 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.

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 moni toring 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

resu lts 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, 1997Page 36 of 38 Permit No. WA0001546
