Article I. General Provisions

14.24.010 Purpose and policy.

(1) This chapter sets forth uniform requirements for users of the publicly owned treatment works (POTW) operated by the city and enables the city to comply with all applicable state and federal laws, including the Clean Water Act (33 USC 1251 et seq.) and the General Pretreatment Regulations (40 CFR Part 403). The objectives of this chapter are:

(a) To prevent the introduction of pollutants into the POTW that will interfere with the operation of the POTW;

(b) To prevent the introduction of pollutants into the POTW which will pass through the POTW, inadequately treated, into receiving waters or otherwise be incompatible with the POTW;

(c) To ensure that the quality of POTW sludge is maintained at a level which allows its use and disposal in compliance with applicable statutes and regulations;

(d) To protect POTW personnel who may be affected by wastewater and sludge in the course of their employment and to protect the general public;

(e) To improve the opportunity to recycle and reclaim wastewater and sludge (biosolids) from the POTW; and

(f) To promote strategies which reduce the amounts of pollutants by users, thereby reducing the associated hazards to the POTW and receiving waters.

(2) This chapter shall apply to all users of the POTW. This chapter defines certain prohibited discharges; sets forth local limits, as defined in WMC 14.24.080, for use by state agencies in the issuance of wastewater discharge permits; authorizes monitoring, compliance and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the recovery of liquidated damages and collection of penalties. (Ord. 1221 § 1, 1996)

14.24.020 Administration.

Except as otherwise provided herein, the Washougal director of public works shall administer, implement and enforce the provisions of this chapter.

(2) Any user determined by the city to qualify as a significant industrial user shall file an application for a State Waste Discharge Permit with Ecology in accordance with the requirements of WAC 173-216-070. Proof of acceptance of the application, and payment of permit fees shall be kept at the user’s facilities, and produced upon request by the city. Failure to submit the application or rejection of the application by Ecology may be considered sufficient grounds to terminate or refuse to provide sewer service. (Ord. 1221 § 1, 1996)

14.24.080 Local limits.

(1) The following pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing in excess of the following daily maximum allowable discharge limits:

0.08 mg/l arsenic;

0.05 mg/l cadmium;

1.3 mg/l chromium;

1.5 mg/l copper;

0.4 mg/l lead;

0.02 mg/l mercury;

3.0 mg/l zinc;

100 mg/l oil and grease (total of petroleum and vegetable based).

(2) The above limits apply at the point where the wastewater is discharged to the POTW (end of the pipe). All concentrations for metallic substances are for “total” metal unless indicated otherwise. Ecology may impose mass limitations in addition to or in place of the concentration-based limitations above. Where a user is subject to a categorical pretreatment standard and a local limit for a given pollutant, the more stringent limit or applicable pretreatment standard shall apply. (Ord. 1221 § 1, 1996)

14.24.090 Right of revision.

The city reserves the right, following a public hearing and public input, to amend this chapter and to establish more stringent standards or requirements on discharges to the POTW. (Ord. 1221 § 1, 1996)

14.24.100 Special agreement.

(1) Users with BOD or TSS levels higher than 300 mg/l in their wastestream must have an agreement with the city before commencing discharge. Within such agreements, the city may establish terms of the user’s discharge to the POTW including maximum flow rates and concentrations. The city may also establish monitoring schedules to insure compliance with the agreement and fees to recover costs associated with treating such wastes. The fees shall be as established according to Article XII of this chapter. In no case will a special agreement waive compliance with a state or federal pretreatment standard or requirement including categorical standards. The user who wishes to make such a discharge must submit a formal request to the city 180 days before the discharge is to occur. The request must include all pertinent data about the discharge including, but not limited to, flow rate, time and duration of discharge(s), type and concentration of pollutants, and any other relevant information requested by the city.

(2) Users discharging or intending to discharge pollutants other than BOD and TSS, and claiming compatibility, must prove to the satisfaction of the director, that such pollutants are compatible with the POTW. The director may require any claim of compatibility to be endorsed by Ecology. (Ord. 1221 § 1, 1996)

14.24.110 Dilution.

No user shall increase the use of process water, or in any way attempt to dilute a discharge, as a partial or complete substitute for adequate treatment to achieve compliance with an applicable pretreatment standard or requirement unless expressly authorized by an applicable pretreatment standard or requirement. The director may request Ecology impose mass limitations on users which he/she believes may be using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate. (Ord. 1221 § 1, 1996)

14.24.120 Pretreatment facilities.

(1) Users will procure, emplace, operate and maintain the wastewater facilities which combined with appropriate practices are necessary to achieve AKART as defined herein. Pretreatment facilities shall be designed to achieve compliance with all applicable pretreatment standards and requirements within the time limitations specified by the EPA or the state, whichever is more stringent. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to Ecology for review and approval in accordance with the procedures of Chapter 173-240 WAC, and shall be disclosed to the city before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce a discharge acceptable to Ecology and meet discharge limitations under the provisions of this chapter. Such facilities shall be provided, operated and maintained at the user’s expense.

(2) Users shall comply with approved engineering reports, plans and specifications, and operations and maintenance manuals, and shall modify such documents to reflect any proposed modifications of industrial wastewater (pretreatment) facilities. Users shall submit proposals to modify pretreatment facilities to the department before implementation in accordance with Chapter 173-240 WAC. Users shall submit a copy of such revised plans and Ecology’s acceptance to the director before implementing changes to approved pretreatment facilities. The city may audit the compliance of any user, and require changes in operating procedures deemed necessary by the director to ensure continued compliance with applicable requirements. (Ord. 1221 § 1, 1996)

14.24.130 Deadline for compliance with applicable pretreatment requirements.

(1) Existing sources covered by one or more categorical pretreatment standards shall comply with such standards within three years of the date the standard is effective unless the pretreatment standard includes a more stringent compliance schedule. Ecology shall establish a final compliance deadline date for any existing user not covered by categorical pretreatment standards or for any categorical user when the local limits for the user are more restrictive than EPA’s categorical pretreatment standards.

(2) New sources and new users shall comply with applicable pretreatment standards within the shortest feasible time, but in no case shall time exceed 90 days from the beginning of discharge. Prior to commencing discharge, such users shall install and start-up all pollution control equipment required to meet applicable pretreatment standards. (Ord. 1221 § 1, 1996)

14.24.140 Additional pretreatment measures.

(1) Whenever deemed necessary, the director may require users to restrict their discharge peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user’s compliance with the requirements of this chapter.

(2) Grease, oil and sand interceptors shall be provided when, in the opinion of the director, they are necessary for the proper handling of wastewater containing grease and oil in excess of the limits in WMC 14.24.080, or excessive amounts of sand. Such interceptors shall not be required for domestic users. All interceptors shall be of type and capacity approved by the director and shall be located to be easily accessible for cleaning and inspection. Each user shall maintain, inspect and clean required interceptors on a schedule that ensures they capture the intended pollutants, and prevents reintroduction into the storm or sanitary sewer systems. Users shall bear all expenses related to installation, maintenance, repair and disposal of removed materials.

(a) Food Service Users. Users who operate restaurants, cafes, lunch counters, cafeterias, bars or clubs, or hotel, hospital, sanitariums, factory or school kitchens, butcher shops, or other establishments where food (polar) grease may be introduced to the sewer system, shall have pretreatment facilities to prevent the discharge of fat waste, oil and grease. Such pretreatment facilities shall be either a grease interceptor or grease trap as determined by the jurisdiction located outside the building, and installed in the wastewater line leading from sinks, drains or other fixtures where grease may be discharged. Grease interceptors shall be required on all new construction projects that have a Type 1 hood exhaust system. New grease interceptors or grease traps shall be in accordance with the Uniform Plumbing Code, and any other requirements by the city as set forth herein. Grease interceptors that include dishwasher effluent shall be sized to allow sufficient detention time to allow for cooling of the effluent. No more than four fixtures shall connect to an individual grease interceptor, and no sanitary facilities will be allowed to connect upstream of any grease interceptor. Subject to the director’s approval, dishwater effluent may be excluded from pretreatment. Grease traps inside the kitchen area will only be allowed under special circumstances and shall only be approved by the director on a case-by-case basis.

(b) Industrial/Commercial User. Users who operate automobile or truck repair facilities, steam cleaning facilities for motorized equipment, air compressor(s), or any other establishments or equipment where petroleum-based (nonpolar) grease and oil may be introduced to the sewer system, shall have pretreatment facilities to prevent the discharge of oil and grease. These pretreatment facilities shall be oil/water separators or interceptors located to collect such mixture of grease, oil and water. Such facilities shall be in accordance with city and state standards.

(c) Retrofit of User Facilities. Users may be required to retrofit facilities which were constructed prior to the adoption of the ordinance codified in this chapter. The requirement to retrofit shall be on a case-by-case basis, as determined by the director for compliance with city, state and federal regulations. The director may require installation of grease interceptors, grease traps or other pretreatment facilities for those facilities that violate discharge prohibitions and supplemental limitations as set forth in this chapter. In all cases, existing food service users that have a Type 1 hood exhaust system shall be required to retrofit with an approved grease trap or interceptor that is sized in accordance with the current Uniform Plumbing Code and its appendices. In deciding whether to require a user to retrofit their facilities, the director shall take into account all relevant circumstances, including but not limited to, the extent of potential harm caused by the discharge, the magnitude and duration of the discharge, economic detriment to the user, corrective actions by the user, the compliance history of the user, and any other relevant factors. Grease interceptor or grease trap size shall be determined in accordance with the Uniform Plumbing Code and any other requirements by the city as set forth herein at the time the user is notified that facility modifications are required. Sizing of grease traps or interceptors will be reviewed and may be modified at the request of the local sewer jurisdiction. All costs incurred in retrofitting a user’s facility shall be the sole responsibility of the user.

(d) Maintenance of Grease Interceptors and/or Grease Traps. Users shall maintain grease interceptors and/or grease traps and/or other pretreatment equipment in a manner that shall prevent fat waste, oil or grease from being carried into the sewer system at all times. Authorized city employees shall be allowed access to grease traps and interceptors for the purpose of inspection and/or to verify compliance with this chapter. Fat waste, oil or grease removed from such a facility shall not be disposed of in the sanitary or storm sewer. A record of disposal shall be maintained for review by the Southwest Washington Health District and the local sewer jurisdiction.

(3) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

(4) Each user discharging more than 10,000 gallons per day or 10 percent of the average daily flow in the POTW, whichever is less, may be required by the director to install and maintain, on his/her property and at his/her expense, a suitable storage and flow-control facility to ensure equalization of flow over a 24-hour period. The facility shall have a capacity for at least 50 percent of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller, the regulation of which shall be directed by the director. The city may require the user to obtain a wastewater discharge permit solely for flow equalization, or to develop a slug control plan (WMC 14.24.150). (Ord. 1571 § 1, 2006; Ord. 1221 § 1, 1996)

14.24.150 Accidental spill/slug discharge control plans.

(1) The director may require any user to install, properly operate, and maintain, at his/her own expense, facilities to prevent slugloads or accidental discharges of pollutants to the POTW. The director may require users to produce and/or implement spill plans developed in compliance with OSHA, health, fire and ecology regulations that address POTW discharges. When such plans are required by the director they shall contain as a minimum the following elements:

(a) A description of discharge practices, including nonroutine batch discharges;

(b) A description of stored chemicals;

(c) Procedures for immediately notifying the city of any accidental or slugload discharges, with procedures for follow-up written notification within five days; and

(d) Procedures to prevent adverse impact from any accidental or slugload discharge, including, but not limited to, the following inspection and maintenance of storage areas; handling and transfer of materials; loading and unloading operations; control of plant site runoff; worker training; building of containment structures or equipment; and measures for emergency response.

(2) Users shall verbally notify the city’s wastewater treatment plant immediately upon the occurrence of a slug or accidental discharge of substances regulated by this chapter and take immediate actions to correct the situation. If the treatment plant cannot be reached, the user shall try to contact City Hall. If City Hall cannot be reached, the fire department shall be notified. Immediate notification does not require placing people in jeopardy of being harmed. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. The user shall follow-up with a written notification to the director containing the same information within seven days following the discharge.

(3) Any user who discharges an accidental discharge or slugload shall be liable for:

(a) Recovery of any resultant expenses, losses and damages to the POTW;

(b) Recovery of any fines or settlements levied upon the city on account thereof by any government agency or court of competent jurisdiction; and

(c) Applicable fines and penalties assessed by the city for noncompliance with this chapter. (Ord. 1221 § 1, 1996)

14.24.160 Septic or liquid hauled wastes.

(1) Septic tank and liquid waste haulers may introduce substances into the POTW only at a designated receiving structure and at such times as are established by the director. No load may be discharged without prior consent of the director.

(2) Such wastes shall not violate any discharge prohibition or standard of this chapter or any other requirements established or adopted by the city. Wastewater discharge permits for individual vehicles to use such facilities shall be issued by the director.

(3) Septage haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the waste hauler, permit number, truck identification, addresses of the sources of waste, and volume and characteristics of waste.

(4) Haulers of liquid wastes other than septage must provide full disclosure to the director of the source or sources of the wastewater, and such additional information as required by the director to characterize the wastewater. The director may issue an authorization on his/her own authority, or require haulers of industrial wastewater to obtain a waste discharge permit as a condition of discharge. No authorization to discharge such wastewater shall be granted until the director has determined to his satisfaction that the wastewater complies with all discharge standards, prohibitions and requirements of this chapter.

(5) The director may exercise absolute discretion in whether to accept any load of septage or hauled wastes. In determining whether to accept a load, the director may collect samples of each hauled load and/or require the hauler to provide a waste analysis of any load prior to discharge.

(6) Fees for discharge of hauled wastes will be established as part of the user fee system as authorized in this chapter. (Ord. 1221 § 1, 1996)

Article III. Wastewater Discharge Permit Requirements

14.24.170 Wastewater discharge permitting – Requirements for discharge.

(1) No significant industrial user (SIU) shall discharge wastewater into the POTW without first applying for a wastewater discharge permit from Ecology. The director may require proof of such application. Obtaining a wastewater discharge permit does not relieve a permittee of his/her obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state and local law including the requirement for applying AKART.

(2) The director may require other users, including liquid waste haulers, to apply for wastewater discharge permits as necessary to carry out the purposes of this chapter.

(3) The director may also establish, and require users by letter, permit or rule, to implement best management practices as determined by the director.

(4) The city encourages all users seeking authorization to discharge to the POTW to complete a pollution prevention review before submitting their request to discharge to the director. The city may require users who must submit a pollution prevention plan under the state of Washington’s Hazardous Waste Reduction Act to provide this plan to the director as a condition of initial or continued discharge. (Ord. 1221 § 1, 1996)

14.24.180 Permit requirements for dangerous waste constituents.

Article V. Sampling and Analytical Requirements

14.24.230 Sampling requirements for users.

(1) Applicable Requirements. Users which discharge to the POTW shall abide by the applicable wastewater monitoring requirements of this chapter, any applicable order, and any state or federal regulation or permit, including a wastewater discharge permit. The director may require self-monitoring as a requirement of discharge to the POTW, or may conduct city monitoring of any discharge to the POTW.

(2) Categorical Users Sampling Requirements. Categorical users with combined discharge shall measure flows and concentrations necessary to allow use of the combined wastestream formula of 40 CFR 403.6(e). Where feasible, such users shall sample immediately downstream from any pretreatment facilities unless the control authority determines end-of-pipe monitoring to be more stringent or applicable.

(3) Noncategorical Users. All other users, where required to sample, shall measure the flows and concentrations necessary to evaluate compliance with pretreatment standards and requirements.

(4) Data Required. All sample results shall indicate the time, date and place, of sampling, and methods of analysis, and shall certify that the samples are representative of normal work cycles and expected pollutant discharges from the user. Whenever a user samples and analyzes any regulated pollutant more frequently than required, using methodologies in 40 CFR Part 136, the results of such analysis shall be submitted with the next required discharge report. (Ord. 1221 § 1, 1996)

14.24.240 Analytical requirements.

All pollutant analyses required to be reported, with the exception of flow and temperature, shall be performed by a laboratory registered or accredited under the provisions of Chapter 173-50 WAC. Sampling and analysis techniques used in collection, preservation, and analysis, shall be in accordance with 40 CFR Part 136 unless otherwise specified in an applicable categorical pretreatment standard. Where 40 CFR Part 136 does not contain sampling or analytical technique for the pollutant in question, a sampling and analyses shall be performed in accordance with procedures approved by EPA or Ecology. (Ord. 1221 § 1, 1996)

14.24.250 City monitoring of wastewater.

The city shall follow the procedures required of users described in WMC 14.24.230 and 14.24.240 whenever conducting wastewater sampling of any industrial user when such sampling is conducted to ensure compliance with this chapter and applicable pretreatment standards and requirements.

Users shall allow the director ready access to all parts of the premises for the purposes of inspection, sampling, records examination and copying, and the performance of any additional duties.

(2) Where a user has security measures in force which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the director, his or her agents or assigns, and representatives of state and federal authority will be allowed to enter without delay for the purposes of performing their respective duties.

(3) For users with wastewater discharge permits, the director, in coordination with Ecology, shall have the right to set up on the user’s property, at the city’s expense, such devices as are necessary to conduct sampling and/or metering of the user’s operations. (Ord. 1221 § 1, 1996)

14.24.270 Monitoring facilities.

(1) Each user shall provide and operate at its own expense a monitoring facility to allow inspection, sampling and flow measurements of each use process waste line connected to the city’s sewer system. Such facilities may be required by Ecology or the city. Monitoring facilities shall be situated on the user’s premises unless this would be impractical or cause undue hardship on the user. In such cases, the director may allow the user to construct the facility in the public street or sidewalk area, providing it will not be obstructed by landscaping or parked vehicles.

(2) The director or applicable control authority may require the construction and maintenance of sampling facilities at other locations (for example, at the end of a manufacturing line, wastewater treatment system) when deemed appropriate.

(3) There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The user shall maintain the facility, sampling and measuring equipment at all times in a safe and proper operating condition at his/her own expense.

(4) All monitoring facilities shall be constructed and maintained in accordance with all applicable local construction standards and specifications. Any devices used to measure wastewater flow and quality shall be regularly calibrated, but no less frequently than annually, to ensure their accuracy.

14.24.280 Search warrants.

(1) If the director or a qualified inspector acting as his/her agent has been refused access to a building, structure or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this chapter, or that there is a need to inspect as part of a routine inspection program of the city designed to verify compliance with this chapter or any order issued hereunder or any wastewater discharge permit issued by Ecology, or to protect the overall public health, safety and welfare of the community, then the director shall seek issuance of a search and/or seizure warrant from the superior court. Such warrant shall be served at reasonable hours by the director in the company of a uniformed police officer of the city.

(2) In the event the director has reason to believe a situation represents an imminent threat to public health and safety, and where entry has been denied or the area is inaccessible, an agent of the director may enter in the company of a uniformed police officer, before a requested warrant has been produced, in order to determine if the suspected situation exists, and if so, to take such actions necessary to protect the public. (Ord. 1221 § 1, 1996)

14.24.290 Vandalism.

No person shall wilfully or negligently break, damage, destroy, uncover, deface, tamper with, or prevent access to any structure, appurtenance or equipment, or other part of the POTW. Any person found in violation of this requirement shall be subject to the sanctions set out in this chapter. (Ord. 1221 § 1, 1996)

Article VII. Confidential Information

14.24.300 Confidential information.

(1) Records kept by the city with respect to the nature and frequency of discharges from any user shall be available to the public without restriction unless the user specifically requests, and is able to demonstrate to the satisfaction of the city, that the release of such information would divulge information, processes or methods of production entitled to confidentiality under the law.

(2) Users shall clearly mark “confidential” on all areas of reports requested to be held confidential from the public. Upon request for this information, the city shall determine if such information is legally afforded this protection under the law. Only information marked “confidential” which the city determines qualifies as such shall be withheld from the public.

(3) Documents claimed as “confidential,” however, shall not be withheld from any state or federal agency responsible for oversight of the city’s NPDES permit or authority to implement the NPDES, or federal or state pretreatment programs. Wastewater constituents and characteristics and other “effluent data” as defined by 40 CFR 2.302 will not be recognized as confidential information and will be available to the public without restriction. (Ord. 1221 § 1, 1996)

Article VIII. Administrative Enforcement Remedies

14.24.310 State responsibility for administrative actions.

The Washington State Department of Ecology is charged with permitting and regulating significant industrial users of the city POTW. Except for emergency actions, it shall be the policy of the director to coordinate actions in regard to control of such users with Ecology until such time as a local pretreatment program for the city may be authorized by the state. Failure to do so, however, shall not invalidate any action of the city authorized by this chapter. (Ord. 1221 § 1, 1996)

14.24.320 Notification of violation.

(1) Whenever the director finds that any industrial user has violated or is continuing to violate any provision of this chapter, or order issued hereunder, the director may serve upon such industrial user written notice of the violation.

(2) Within 10 days of receipt of a notice of violation, the user shall submit an explanation of the violation and a plan for the satisfactory correction and prevention thereof, to include specific required actions to the director. Submission of this plan in no way relieves the user of liability for any violations occurring before or after receipt of the notice of violation.

(3) Nothing in this section shall limit the authority of the city to take any action, including emergency actions or any other enforcement action, without first issuing a notice of violation. (Ord. 1221 § 1, 1996)

14.24.330 Consent orders.

(1) The director is empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with any industrial user responsible for noncompliance. Such consent orders shall include a specific action to be taken by the industrial user to correct the noncompliance within a time schedule also specified by the consent order.

(2) Compliance schedules, when included in consent orders, may not extend the compliance date beyond any applicable state or federal deadlines. Consent orders shall have the same force and effect as compliance orders issued pursuant to WMC 14.24.340 and shall be judicially enforceable.

(3) Failure to comply with any terms or requirements of a consent order by the user shall be an additional and independent basis for termination of wastewater services, including collection and treatment, or for any other enforcement action authorized under this chapter and deemed appropriate by the director. (Ord. 1221 § 1, 1996)

14.24.340 Compliance orders.

(1) Whenever the director finds that a user has violated, or continues to violate, any provision of this chapter, or order issued hereunder, the director may issue a compliance order to the industrial user responsible for the violation directing that, following a specified time period, wastewater services, including collection and treatment, shall be discontinued and/or applicable penalties imposed unless adequate pretreatment facilities, devices or other related appurtenances have been installed and are properly operated and maintained.

(2) Compliance orders may also contain such other requirements as might be reasonably necessary and appropriate to address the noncompliance, including, but not limited to, the installation of pretreatment technology, additional self-monitoring, and management practices designed to minimize the amount of pollutants discharged to the POTW. A compliance order may not extend the deadline for compliance beyond any applicable state or federal pretreatment standard or requirement, nor does a compliance order release the industrial user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a prerequisite to taking any other action against the industrial user.

(3) Failure to comply with any terms or requirements of a compliance order by the industrial user shall be an additional and independent basis for termination of wastewater services, including collection and treatment, or for any other enforcement action authorized under this chapter and deemed appropriate by the director. (Ord. 1221 § 1, 1996)

14.24.350 Show cause hearing.

A user shall also have the right to a hearing prior to termination of the user’s wastewater services.

(2) Notice shall be served on the user specifying the time and place for the meeting, the proposed enforcement action, the reasons for such action, and a request that the user show cause why the proposed enforcement action should not be taken. The notice of the meeting shall be served on an authorized representative of the user (return receipt requested) at least 15 days prior to the scheduled hearing date.

(3) A show cause hearing shall not be a bar against, or prerequisite for, taking any other action against the user. (Ord. 1221 § 1, 1996)

14.24.360 Cease and desist orders.

(1) When the director finds that a user has violated (or continues to violate) any provision of this chapter, a wastewater discharge permit or order by Ecology, or any other pretreatment standard or requirement, or that the user’s past violations are likely to recur and may cause a violation of the POTW’s NPDES permit, the director may issue an order to the user directing it to cease and desist all such violations and directing the user to:

(a) Immediately cease such actions or discharges as described;

(b) Comply with all applicable pretreatment standards and requirements;

(c) Take such appropriate remedial or preventive action as may be needed to properly address a continuing or threatened violation, including halting operations and/or terminating the discharge.

(2) Issuance of a cease and desist order shall not be a bar against, or a prerequisite for, taking any other action against the user. (Ord. 1221 § 1, 1996)

14.24.370 Emergency suspension of wastewater services.

(1) The director may immediately suspend wastewater services including collection and treatment, after informal notice to the user, if it appears to the city that such suspension is necessary to stop an actual or threatened discharge which reasonably appears to present or cause an imminent or substantial endangerment to either the environment, normal operation of the POTW, or the health or welfare of any person or the general public.

(2) Any user notified of a suspension of its discharge shall immediately cease all wastewater discharges. In the event of a user’s failure to immediately comply voluntarily with the suspension order, the director shall take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or the danger to the public. The director may allow the user to recommence its discharge when the user has demonstrated that the period of endangerment has passed unless the termination processings in WMC 14.24.380 are initiated against the user.

(3) It is unlawful for any person to prevent or attempt to prevent the city from terminating wastewater services in an emergency situation, by barring entry, by physically interfering with city employees or contractors, or by any other means.

(4) A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the director prior to the date of any show cause or termination hearing authorized by this chapter.

(5) Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this section. (Ord. 1221 § 1, 1996)

14.24.380 Termination of treatment services (nonemergency).

(1) The director shall have authority to terminate wastewater services, including collection and treatment, for any user upon determining that such user has:

(a) Refused access allowed by this chapter thereby preventing the implementation of any purpose of this chapter;

(b) Violated any provision of this chapter including the discharge prohibitions and standards of Article II; or

(c) Violated any lawful order of the city issued with respect to this chapter.

(2) For users holding permits to discharge to the POTW, violation of the following conditions is also grounds for terminating discharge services:

(a) Failure to accurately report wastewater constituents and characteristics;

(b) Failure to report significant changes in operations or wastewater constituents or characteristics;

(c) Violation of any condition of the user’s waste discharge permit.

(3) Issuance of a termination order by the city shall not be a bar to, or a prerequisite for, taking any other action against the user. (Ord. 1221 § 1, 1996)

Article IX. Judicial Enforcement Remedies

14.24.390 Injunctive relief.

When the director finds that a user has violated (or continues to violate) any provision of this chapter, a wastewater discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the director may petition the superior court through the city attorney for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, or other requirement imposed by this chapter on activities of the user. The city may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the user to conduct environmental remediation. A petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against a user. (Ord. 1221 § 1, 1996)

14.24.400 Civil penalties.

(1) A user which has violated or continues to violate any provision of this chapter, or order issued hereunder, or any other pretreatment standard or requirement not reserved by a permit by Ecology shall be liable to the city for a maximum civil penalty of $10,000 per violation. Each day upon which a violation occurs or continues shall constitute a separate violation. In the case of a monthly or other long-term average discharge limits, penalties shall accrue for each day during the period of the violation.

(2) In addition to the penalty amounts assessable under subsection (1) of this section, the director may recover reasonable attorneys’ fees, court costs, and other expenses associated with enforcement activities, including sampling and monitoring expenses, and the cost of any actual damages incurred by the city including penalties for noncompliance with the city’s NPDES permit to the extent attributable to the user.

(3) The city shall petition the superior court to impose, assess and recover such sums. In recommending the amount of civil liability, the director shall consider all relevant circumstances, including, but not limited to, the extent of harm caused by the violation, the magnitude and duration, any economic benefit gained through the user’s violation, corrective actions by the user, the compliance history of the user, and any other factor as justice requires, and shall present this analysis as evidence in support of the recommended penalty.

(4) Filing a suit for civil penalties shall not be a bar against, or a prerequisite for, taking any other action against a user. (Ord. 1221 § 1, 1996)

14.24.410 Criminal prosecution.

(1) A user which wilfully or negligently violates any provision of this chapter, or order issued hereunder, or any other pretreatment standard or a requirement shall, upon conviction, be guilty of a misdemeanor, punishable by a fine of not more than $10,000 per violation, per day, plus costs of prosecution or imprisonment in the county jail not to exceed one year, or by both fine and imprisonment, at the discretion of the superior court.

(2) The above provision applies to any user which knowingly makes any false statements, representations or certifications in any application, record, report, plan or other documentation filed, or required to be maintained, pursuant to this chapter, wastewater discharge permit, or order issued hereunder, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under this chapter.

(3) Where wilful or negligent introduction of a substance into the POTW causes personal injury or property damage, this action shall be in addition to any other civil or criminal action for personal injury or property damage available under the law. (Ord. 1221 § 1, 1996)

14.24.420 Remedies nonexclusive.

The provision in Articles VIII through XI of this chapter are not exclusive remedies. The city reserves the right to take any, all, or any combination of these actions concurrently or sequentially against a noncompliant user or to take other actions as warranted by the circumstances. (Ord. 1221 § 1, 1996)

Article X. Supplemental Enforcement Actions

14.24.430 Water supply severance.

Whenever a user has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, water service to the user may be severed. Service will only recommence, at the user’s expense, after it has satisfactorily demonstrated its ability to comply. (Ord. 1221 § 1, 1996)

14.24.440 Performance bonds and liability insurance.

The director may decline to reinstate wastewater service for any industrial user who has had its wastewater services suspended or terminated under the provisions of this chapter unless such industrial user, at the discretion of the director and the city council, either: (1) first files with the city a satisfactory bond, payable to the city, in a sum not to exceed a value determined by the director to be necessary to achieve compliance; or (2) first submits proof that it has obtained financial assurances sufficient to restore or repair POTW damage caused by its discharge. (Ord. 1221 § 1, 1996)

14.24.450 Innovative settlements and supplemental environmental projects.

(1) In any enforcement action allowed under this chapter, the director may recommend and the city may agree to set aside all or portions of the recommended penalty amount in lieu of requiring completion of a project of environmental benefit to the POTW of equal or greater value. Such projects must be agreed to by the user.

(2) In recommending this option, the director shall consider all relevant circumstances, including, but not limited to, the net environmental benefit, the ability of the project to help achieve or ensure compliance, the willingness of the party to change the circumstances that led to the noncompliance, and the responsible party’s technical and financial ability to successfully complete the project.

(3) In enforcement actions taken by the Department of Ecology, the city may make written recommendations either for or against an innovative settlement agreement with a noncompliant user based on these same criteria. (Ord. 1221 § 1, 1996)

Article XI. Affirmative Defenses to Discharge Violations

14.24.460 General prohibited discharge standards.

(1) The city may allow an affirmative defense to an enforcement action brought against it for noncompliance with the general and specific prohibitions in WMC 14.24.050(1) and (2)(c) through (g). Such defense requires the user to prove to the satisfaction of the director that:

(a) The user did not know or have reason to know that its discharge, alone or in conjunction with discharges from other sources, would cause pass through or interference;

(b) The discharge did not change substantially in nature or constituents from the industrial user’s prior discharge when the city was regularly in compliance with its NPDES permit; and

(c) In the case of interference, the user was in compliance with applicable sludge use or disposal requirements.

(2) This defense may relieve the user from responsibility for enforcement to recover costs as provided under WMC 14.24.400. (Ord. 1221 § 1, 1996)

14.24.470 Upset.

(1) Users shall control production or all discharges to the extent necessary to maintain compliance with applicable pretreatment standards upon reduction, loss or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost or fails.

(2) An industrial user who wishes to establish the affirmative defense of upset to an action brought for noncompliance with applicable pretreatment shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

(a) An upset occurred; the user can identify the cause(s) of the upset; and it was not due to improperly designed or inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation;

(b) The facility was at the time being operated in a prudent and workman-like manner and in compliance with applicable operation and maintenance procedures; and

(c) The user has verbally notified the city’s wastewater treatment plant (or City Hall or fire department as described in WMC 14.24.150) immediately, if possible, but no later than 24 hours upon becoming aware of the upset. Immediate notification does not require placing people in jeopardy of being harmed. The notification must include the following information. A written report must have been submitted within five days:

(i) A description of the indirect discharge and cause of noncompliance;

(ii) The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and

(iii) Steps being taken and/or planned to reduce, eliminate and prevent recurrence of the noncompliance.

(3) Users will only have the opportunity for a judicial determination on a claim of upset in an enforcement action brought for noncompliance with applicable pretreatment standards. In any such enforcement proceedings, the user seeking to establish the occurrence of an upset shall have the burden of proof. (Ord. 1221 § 1, 1996)

14.24.480 Bypass.

(1) A user may allow a bypass to occur if it does not cause applicable pretreatment standards or requirements to be violated and if it is for essential maintenance to ensure efficient operations. These bypasses are not subject to the provision of subsections (2) and (3) of this section.

(2) Requirements for bypasses subject to pretreatment standards or requirements:

(a) If a user knows in advance of the need for a bypass, it shall submit prior notice to the POTW, at least 10 days before the date of the bypass.

(b) An industrial user shall give verbal notification to the city of an unanticipated bypass that exceeds applicable pretreatment standards within 24 hours of becoming aware of the bypass, and submit a written report to the director within five days of becoming aware of the bypass.

(c) The written report shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate and prevent reoccurrence of the bypass. The director may waive the written report if the verbal notification has been received within 24 hours.

(3) Exceptions. Bypass is prohibited, and the POTW may take an enforcement action against a user for a bypass, unless:

(a) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;

(b) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and

(c) The user submitted notice as required under subsection (2) of this section.

(4) The POTW may approve an anticipated bypass, after considering its adverse effects, if the POTW determines that it will meet the three conditions listed in subsection (3) of this section. (Ord. 1221 § 1, 1996)

Article XII. Industrial Waste Collection and Treatment Rates

14.24.490 Purpose.

It is the purpose of this section to provide for the payment of charges from industrial users to compensate the city for the cost of installing, operating, maintaining and further improving the POTW and for the cost of administration of the pretreatment program established herein. (Ord. 1221 § 1, 1996)

14.24.500 Sewer use service charges.

(1) Any industrial user who has a process wastewater which is discharged into the city’s sewer and is equivalent to domestic sewage except that the BOD or TSS levels may be higher than 300 mg/l shall pay a fee based on the domestic sewage rates established in the WMC and an equivalent domestic population. To determine the equivalent domestic population, each person is assumed to generate 0.2 pounds of BOD per day and 0.2 pounds of TSS per day. The director of public works shall determine if an industrial wastewater is equivalent to domestic sewage and, if so, the equivalent domestic population to be used in the fee calculation. The city council shall approve the director’s determination.

(2) Any industrial user who has a process wastewater which is not equivalent to domestic sewage (see subsection (1) of this section) shall pay a fee to be determined by the director and approved by the city council for the cost of accommodating the waste.

(3) The city reserves the following rights:

(a) To modify the above rates to reflect changes in POTW facilities, labor costs, requirements in the city’s NPDES permit, biosolids land application program, and costs of materials and supplies;

(b) To periodically review the characteristics of an industrial wastewater and modify the fee by council action based on the results of such review. (Ord. 1221 § 1, 1996)
