A. General All discharges and activities authorized by this permit shall be consistent with the terms and conditions of this permit.

The discharge of any pollutant not specifically authorized by this permit in.

concentrations which cause or contribute to a violation of water quality standards established under Section 307(a) of the Clean Water` Act,& Chapter'173-201A Washington Administrative Code (WAC) shall also be a violation of this permit and the Clean Water Act.

Proper Operation and Maintenance The Permittee shall, at all times, properly operate and maintain all facilities or systems of treatment and control (and related appurtenances) which are installed to achieve compliance with the terms' and cohidifio!L,, ofthis permit.;'Proper' operition"and maintenance also includes adeuaite :laboratdiy contreols and appropriate quality assurance procedures.: iThis provision.requires the operation of bac-k-tip or auxiliary facilities§ or similar systems, which -are.iiitalledby the' Perfmittee only when the operation is necessary to, achieve compliance -with the coniditions; of this pe'rmit.

B. Bypass Procedures Bypass, which is the intentional diversion of waste streams from any portion of a treatment process,. is prohibited, and the, Council 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.

Bypass is authorized if it is for essential maintenance and does not. have the potential to cause violations of limitations or other conditions of this permit, or adversely impact public health as determined by the Council prior to the bypass.

Tfhe Permittee shall submit prior notice at least ten (10) 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-

a. Bypass is unavoidable to prevent loss of life, personal injur y, or severe property damage. "Severe property damage"-means substantial phy~sical %iamage 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. 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. lWe been installed in the exercise of reasonable engineering judgement to prevent a bypass which occurred during normal periods of equipment downtime or preventative maintenance), or transport of untreated wastes to another treatment facility.

For probable construction bypasses, the need to bypass shall be identified as early in the planniing-procdess a'spossiblE ýThe analysisi required above shall be considered during preparation of the engineering report or facilities plan and plans and specifications and shall be included to the extent practical. In cases where the prohiible need to bypass is determined early, the Permittee shall continue to analyze

-up to and including the'constructio'n period, in an effort to minimize or eliminate the

'bypass.

The Council will consider the following prior to issuing an administrative order for this type bypass:

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, retenitio'n of untreated w~ast es, stoppin3g production, maintenance during niormal Oeriods of e4ui~pmdnt d~own time, or transort of untreated wastes

-toanother treatmient facility.

c. If the bypass is planned and ýschduiled -tominimize adverse effects on the public and the environment.

-After consideration~o h above and the adverse effects of the proposed bypass and any other relevanft factors, the Council Will lapprove or deny the request. The public

ýshall be notified and ~Ivn gn opportunity to commenit oni bypass inicidents of significant duration, -to'the-exitenit feasible. Appvroval of a request to bypass will be by administrative order issued by the Council under RCW 90.48..
