Bypass Procedures Bypass, which is the intentional diversion ofwaste streams from anyportion ofa treatment facility, is prohibited, and the Departmentmaytake enforcement action against a Permittee for bypass unless one ofthe following circumstances (1, 2, or 3) is applicable. 1. Bypass for Essential Maintenance without the Potential to Cause Violation of Permit Limits or Conditions. Bypass is authorized ifit is for essential maintenance and does not have the potential to cause violations oflimitations or other conditions ofthis permit, or adversely impactpublic health as determined bythe Departmentprior to the bypass. The Permittee shall submit prior notice, ifpossible, at least ten (10) days before the date ofthe bypass. 2. Bypass Which is Unavoidable, Unanticipated, and Results inNoncompliance ofthis Permit. · This bypass is permitted only if: Bypass is unavoidable to prevent loss oflife, personal injury, or severe property damage. "Severeproperty damage" means substantial physical damage to property, damage to thetreatment facilities which would cause themto becomePage 21 of44 Permit No. WA 000080-9 inoperable, or substantial andpermanent loss ofnatural resources which can reasonably be expected to occur in the absence ofa bypass. There are no feasible alternatives to thebypass, such as the use ofauxiliary treatment facilities, retention ofuntreated wastes, stopping production, maintenance during normal periods ofequipment downtime (but notifadequate backup equipment should have been installed inthe exercise ofreasonable engineeringjudgmentto prevent a bypass which occurred during normal periods ofequipment downtime or preventative maintenance), or transport of untreated wastes to another treatment facility. The Department is properly notified ofthe bypass as required in condition S3E of this penni t. 3. Bypass whichis Anticipated and has the Potential to Result inNoncompliance of this Permit. The Permittee shall notify the Department at least thirty (30) days before the planned date ofbypass. The notice shall contain (1) a description ofthe bypass and its cause; (2) an analysis ofall known alternatives whichwould eliminate, reduce, or mitigate the need for bypassing; (3) a cost-effectiveness analysis ofalternatives including comparative resource damage assessment; (4) the minimum and maximum duration ofbypass under each alternative; (5) a recommendation as to the preferred alternative for conducting the bypass; (6) the projected date ofbypass initiation; (7) a statement ofcompliance with SEPA; (8) a request for modification ofwater quality standards as provided for in WAC 173-201A-110, ifan exceedance ofany water quality standard is anticipated; and (9) steps taken or planned to reduce, eliminate, and prevent reoccurrence ofthe bypass. For probable constructionbypasses, the need to bypass is to be identified as early in the planning process as possible. The analysis required above shall be considered during preparation ofthe engineering report or facilities plan and plans and specifications and shall be included to the extentpractical. In cases where the probable needto bypass is determined early, continued analysis is necessary up to and including the constructionperiod in an effort to minimize or eliminate the bypass. The Departmentwill considerthe following prior to issuing an administrative order for this type bypass:

a. Ifthe bypass is necessary to perform construction or maintenance-related activities essential to meet the requirements ofthis permit. b. Ifthere are feasible alternatives to bypass, such as the use ofauxiliarytreatment facilities, retention ofuntreated wastes, stopping production, maintenance during normal periods ofequipment downtime, or transport ofuntreated wastes to anothertreatment facility.Page 22 of44

Ifthe Permittee believes that a test indicating noncompliance will be identified bythe Department as an anomalous test result, the Permittee may notify the Department that the compliance test result might be anomalous and that the Permittee intends to take only one additional sample for toxicity testing and wait for notification from the Department before completing the additional monitoring required in this subsection. The notificationto the Department shall accompany the report ofthe compliance test result and identify the reason for considering the compliance test result to be anomalous. The Permittee shall complete all ofthe additional monitoring required in this subsection as soon as possible after notification bythe Departmentthatthe compliance test result was not anomalous. Ifthe one additional sample fails to comply withthe effluent limit for acute toxicity, then the Permittee shall proceed without delay to complete all ofthe additional monitoring required inthis subsection. The one additional test result shall replace the compliance test result upon determination by the Department that the compliance test result was anomalous. Ifall ofthe additional compliance monitoring conducted in accordance withthis subsection complies with the permit limit, the Permittee shall search all pertinent and recent facility records (operating records, monitoring results, inspectionrecords, spill reports, weather records, production records, raw material purchases, pretreatment records, etc.) and submit a report to the Department onpossible causes and preventive measures for the transient toxicity event whichtriggeredthe additional compliance monitoring. Iftoxicity occurs in violation ofthe acute toxicity limit during the additional compliance monitoring, the Permittee shall submit a Toxicity Identification/Reduction Evaluation (TIIRE) plan to the Department within 60 days after test results are final. The TI/RE plan shall be based onWAC 173-205-100(2) and shall be implemented in accordance with WAC 173-205-100(3).Page 26 of44 PermitNo. W A 000080-9 E.

Ifthe difference in response between the control and the CCEC sample is less than 20%, the hypothesis test shall be conducted at the 0.01 level ofsignificance. In order to establishwhether the chronic toxicity limit is eligible for removal from future permits, the Permittee shall also conductthis same hypothesis test (Appendix H, EPA/600/4-89/001) to determine whether a statistically significant difference in response exists betweenthe ACEC and the control sample. D. Response to noncompliance with an effluent limit for chronic toxicity outfall Ifatoxicity test conducted for compliance monitoring under subsection C.determines a statistically significant difference inresponse betweenthe CCEC and the control sample, the Permittee shall begin additional compliance monitoring within one week from the time ofreceiving the test results. This additional monitoring shall be conducted monthly for three consecutive months using the same test and species as the failed compliance test. Testing shall be conducted using a series ofat least five effluent concentrations and a control sample to determine appropriate point estimates. One of these effluent concentrations shall equal the CCEC and be compared statistically to the nontoxic control in order to determine compliance with the effluent limit for chronic toxicity as described in subsection C. The discharger shall return to the original monitoring frequency in subsection C after completion ofthe additional compliance monitoring. Ifthe Permittee believes that a test indicating noncompliance will be identified by the Department as an anomalous test result, the Permittee may notify the Departmentthat the compliance testresult might be anomalous and that the Permittee intends to take only one additional sample for toxicitytesting and wait for notification from the Departmentbefore completing the additional monitoring required in this subsection

.. The notificationto the Department shall accompany the report ofthe compliance test result and shall also identifythe reason for considering the compliance test result to be anomalops. The Permittee shall complete all ofthe additional monitoring required in this subsection as soon as possible after notificationby the Department that the compliance test result was not anomalous. Ifthe one additional sample fails to complyPage 29 of44 PermitNo. W A 000080-9 withthe effluent limit for chronic toxicity, then the Permittee shall proceed without delay to complete all ofthe additional monitoring required in this subsection. The one additional test result shall replace the compliance test result upon determinationbythe Department that the compliance test result was anomalous. Ifall ofthe additional compliance monitoring conducted in accordance with this subsection complies withthe permit limit, the Permittee shall search all pertinent and recent facility records (operating records, monitoring results, inspection records, spill reports, weather records, productionrecords, raw material purchases, pretreatment records, etc.) and submit a report to the Depmiment onpossible causes and preventive measures for the transient toxicity event whichtriggered the additional compliance monitoring. Iftoxicity occurs in violation ofthe chronic toxicity limit during the additional compliance monitoring, the Pe1mittee shall submit a Toxicity Identification/Reduction Evaluation (TI/RE) plan to the Department within 60 days after test results are final. The TI/RE plan shall be based on WAC 173-205-100(2) and shall be implemented in accordance with WAC 173-205-100(3). E. Sampling and Reporting Requirements for Outfall 001 1.
