Part 1. General Provisions

7.65.010 Purpose and policy.

This chapter sets forth uniform requirements for dischargers into the city of Yakima’s (city) publicly owned treatment works (POTW), and enables the city to protect public health in conformity with all applicable local, state and federal laws relating thereto, including the Clean Water Act (33 U.S.C. 1251 et seq.) and the General Pretreatment Regulations (40 CFR part 403). This chapter shall apply to all users of the POTW.

The objectives of this chapter are the following:

1.    To promote the health, safety and welfare of those persons within the city’s sewer service area;

2.    To ensure proper and safe connections to the POTW;

3.    To prevent the introduction into the POTW that could interfere with the normal operation of the POTW;

4.    To prevent the introduction of pollutants into the POTW that would not receive adequate treatment in the POTW and that would pass through the POTW into receiving waters or the atmosphere or otherwise be incompatible with the POTW;

5.    To ensure that the quality of biosolids from the POTW is maintained at a level which allows its utilization and beneficial reuse in compliance with applicable statutes and regulations;

6.    To protect POTW personnel who may be affected by wastewater and biosolids in the course of their employment and to protect the general public;

7.    To improve the opportunity to recycle and reclaim wastewater and biosolids from the POTW; and

8.    To enable the city to comply with its NPDES permit conditions, biosolids utilization and beneficial reuse requirements and any other federal or state laws to which the POTW is subject.

This chapter provides for the regulation of discharges into the city’s wastewater system through the enforcement of administrative regulations. This chapter authorizes monitoring, compliance, and enforcement activities; establishes administrative review procedures; and requires discharger reporting. This chapter also authorizes the city’s wastewater division to issue and enforce wastewater discharge permits. With the issuance of the city’s June 15, 2003, NPDES permit, the Washington State Department of Ecology fully delegated to the city a wastewater pretreatment program pursuant to 40 CFR Part 403 and WAC Chapter 173-208. This chapter does not provide for the recovery of operations, maintenance or replacement costs of the POTW or the costs associated with the construction of collection and treatment systems used by industrial dischargers, in proportion to their use of the POTW, which are the subject of separate enactments. (Ord. 2003-74 § 1 (part), 2003).

7.65.015 Administration.

Except as otherwise provided, the wastewater manager shall administer, implement, and enforce the provisions of this chapter. Any powers granted to or duties imposed upon the wastewater manager may be delegated by the wastewater manager to other city personnel. (Ord. 2003-74 § 1 (part), 2003).

The licensed and bonded contractor shall have taken and passed the side sewer installer certification test that is proctored by the code administration and planning division of the city of Yakima.

D.    A separate and independent building sewer shall be provided for every building, and only on each building’s separate and independent lot, except under the following circumstances:

1.    Where one building stands in the rear of another building on an interior lot, and no private sewer is available or can be constructed to the rear building through an adjoining court, yard or driveway, the building drain from the front building may be extended to the rear building and the whole considered as one building sewer; or

2.    Where other circumstances, established to the satisfaction of the code administration and planning manager, indicate the need for a single sewer connection between separate and independent lots and there is a legally valid easement over the subservient lot.

The city does not and will not assume any obligation or responsibility for damage caused by or resulting from any single connection.

E.    Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the code administration and planning manager, to be in good repair, sized for the number of fixtures per the plumbing code most recently adopted by the city, to be suitable for this purpose, and to meet all requirements of this chapter.

F.    The size, slope, alignment, materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench, shall all conform to the edition of the plumbing code most recently adopted by the city.

G.    Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by any approved means described in the edition of the plumbing code most recently adopted by the city and found acceptable by the code administration and planning manager, and discharged to the building sewer.

H.    No person shall make connection of roof downspouts, foundation drains, areaway drains or other sources of surface runoff, stormwater or groundwater to a building sewer or building drain, which in turn is connected directly or indirectly to a public sewer, or maintain such a connection.

I.    The connection of the building sewer into the public sewer shall conform to the requirements of the editions of the building code and plumbing code most recently adopted by the city. All such connections shall be made gastight and watertight and verified by proper testing. The code administration and planning manager must approve any deviation from the prescribed procedures and materials before installation.

J.    The applicant for the building sewer permit shall notify the code administration and planning manager when the building sewer is ready for inspection and connection to the public sewer. The connection and testing shall be made under the supervision of the code administration and planning manager.

K.    All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the city.

L.    A properly functioning backwater valve shall be required in any building containing a basement, except in those situations which would not require a backwater valve as described in the edition of the building code most recently adopted by the city. The permit to install a backwater valve can be obtained from the code administration and planning manager. The city shall not be liable for damage due to wastewater backing up into a building where a properly functioning backwater valve has not been installed. The city also shall not be liable for damage due to wastewater backing up into a building where a backwater valve has been installed but has not been properly maintained or repaired. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

8.    Any wastewater containing pollutants in sufficient quantity or concentration, either singly or by interaction, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or to exceed the limitation set forth in categorical pretreatment standards, or state or local standards.

9.    Any pollutants which result in the presence of toxic, noxious or malodorous liquids, gases, vapors, fumes or solids within the POTW in a quantity that either singly or by interaction are capable of creating a public nuisance or hazard to life or causing acute worker health and safety problems, or are sufficient to prevent entry into the sewers for their maintenance and repair.

10.    Any substance which may cause the POTW’s effluent or treatment residues, biosolids or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance be discharged to the POTW that, either alone or in combination with other discharges, will cause the POTW to be in noncompliance with biosolids use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; or with any criteria, guidelines or regulations affecting biosolids use or disposal developed pursuant to the Solid Waste Disposal Act, 42 U.S.C. 6901 et seq., as now or as it may be amended, the Clean Air Act, 42 U.S.C. 7401 et seq., as now or as it may be amended, the Toxic Substances Control Act (TSCA), 15 U.S.C. 2601 et seq., as now or as it may be amended, or similar state statutes or regulations applicable to the biosolids management method being used.

11.    Any substance which will cause the POTW to violate its NPDES and/or other disposal system permits.

12.    Any wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant’s effluent thereby violating the city’s NPDES permit. Color, alone or in combination with turbidity, shall not cause the treatment plant effluent to reduce the depth of the compensation point for photosynthetic activity by more than ten percent from the seasonably established norm for aquatic life.

13.    Any slugload.

14.    Any sludges, screenings or other residues from the pretreatment of industrial wastewater discharges.

16.    Any wastewater that causes a hazard to human life or creates a public nuisance.

17.    Any medical wastes.

18.    Any wastewater causing the treatment plant’s effluent to fail a toxicity test.

19.    Any wastes containing detergents, surface-active agents, or other substances in such concentrations that they may cause excessive foaming in the POTW.

20.    Persistent pesticides and/or pesticides regulated by the Federal Insecticide Fungicide Rodenticide Act (FIFRA), 7 U.S.C. 136 et seq., as now or as it may be amended.

C.    No discharger shall discharge or cause to be discharged to the POTW, directly or indirectly, any of the following described substances unless discharged pursuant to a valid wastewater discharge permit or authorization from the wastewater manager:

1.    Any wastewater with a temperature that will inhibit biological activity in the POTW treatment plant resulting in interference; but, in no case, wastewater with a temperature at the introduction into the POTW which exceeds forty degrees centigrade (one hundred four degrees Fahrenheit).

2.    Any trucked or hauled pollutants, except pursuant to YMC 7.65.420.

3.    Any dangerous wastes as defined in Chapter 173-303 of the Washington Administrative Code (WAC), as now or as it may be amended.

4.    Flows which have the potential to adversely affect the hydraulic loading of the POTW, including the following categories:

a.    Noncontact cooling water;

b.    Stormwater and other direct inflow sources; and

c.    Nonpolluted water or water which does not require significant treatment.

D.    Wastes prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW. All floor drains located in process or materials storage areas must discharge to the industrial discharger’s pretreatment facility prior to discharging to the POTW.

E.    The general and specific prohibitions provided by this section apply to all dischargers to the POTW whether or not the discharger is subject to categorical pretreatment standards or requirements. (Ord. 2010-54 § 1, 2010: Ord. 2007-26 § 1 (part), 2007: Ord. 2006-07 § 26, 2006: Ord. 2003-74 § 1 (part), 2003).

7.65.070 Limitations on wastewater strength.

A.    National categorical pretreatment standards as adopted and hereafter amended or modified by the U.S. Environmental Protection Agency (EPA) pursuant to the Act shall be met by all dischargers of the regulated industrial categories. The national categorical standards found at 40 CFR Chapter I, Subchapter N, Parts 405 through 471 are hereby incorporated.

B.    State requirements and limitations on discharges to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations, or those in this chapter or any other applicable ordinance.

C.    The city may from time to time amend this chapter to provide for more stringent limitations or requirements on discharges to the POTW if such amendments are deemed necessary to comply with the objectives set forth in YMC 7.65.010, or are otherwise in the public interest.

D.    No discharger shall dilute its waste stream with potable or process water in any way, nor mix separate waste streams for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this chapter.

E.    No discharger shall discharge wastewater containing concentrations (and/or mass limitations) that exceed any of the following local discharge limits unless prior written approval has been obtained from the wastewater division:

(1)    All pollutants are analyzed and reported as total mg/L.

(2)    BTEX is the sum of the measured concentrations of benzene, toluene, ethylbenzene and xylene.

(3)    These pollutants are based upon treatment technology (air stripping/carbon capture) and are developed for discharges from groundwater cleanup or remediation activities or other effluents containing benzene and/or BTEX and requiring the installation of treatment.

The above limits apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for “total” metal unless indicated otherwise. An industrial user, through enforcement action and/or permit compliance schedule, may be required to install treatment or otherwise reduce or halt a discharge of a pollutant to maintain compliance with pretreatment standards and requirements and prevent interference with the operation of the POTW, pass through and adverse effects on the quality of the receiving waters, contamination of municipal biosolids, health and safety hazards to workers in the POTW, or violations of applicable federal or state regulations. The city may impose mass limitations on discharges in cases where necessary to be consistent with federal categorical pretreatment standards. Where a discharger 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. The city may establish more stringent pollutant limits, mass-based limits, additional site-specific pollutant limits, best management practices, or additional pretreatment requirements when, in the judgment of the city, such limitations are necessary to implement the provisions of this chapter.

F.    All known, available and reasonable methods of pretreatment, in accordance with RCW 90.48.010 and WAC 173-216-020(1), shall be used by a discharger to bring into compliance a wastewater discharge that does not comply with standards set forth in this chapter.

G.    The city reserves the right to enter into special agreements with industrial dischargers setting out special terms under which they may discharge wastewater to the POTW. In no case will a special agreement waive compliance with a pretreatment standard or requirement. However, the industrial discharger may request a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. They may also request a variance in accordance with 40 CFR 403.13 from the categorical pretreatment standard from EPA. Such a request will be approved only if the industrial discharger can prove that factors relating to its discharge are fundamentally different from the factors considered by EPA when establishing that pretreatment standard. An industrial discharger requesting a fundamentally different factor variance must comply with the procedural and substantive provision in 40 CFR 403.13. (Ord. 2010-54 § 2, 2010: Ord. 2006-07 § 27, 2006: Ord. 2003-74 § 1 (part), 2003).

7.65.080 Slugload or accidental discharges.

A.    Each discharger shall provide protection from a slugload or accidental discharge of prohibited or regulated materials or substances established by this chapter. Where the city deems it necessary, a discharger shall provide and maintain, at the discharger’s own cost and expense, facilities and operating procedures to prevent a slugload or accidental discharge of prohibited materials. When requested to do so, the discharger shall submit to the wastewater manager for review a “slugload control/spill prevention, control and countermeasure plan” (SC/SPCC plan) showing facilities and operating procedures to provide this protection. The wastewater manager shall evaluate, at least once every two years and within one year of a user’s initial designation as a significant industrial discharger, whether each significant industrial user needs an SC/SPCC plan. The SC/SPCC plan shall contain at a minimum the following elements:

1.    Description of discharge practices for batch and continuous processes, including nonroutine and routine batch discharges;

2.    Description of stored hazardous substances, including quantity maintained for each listed material and a map showing their location;

3.    Procedures for immediately notifying the city and any other authorities of any accidental or slugload discharges, with procedures for follow-up written notification within five days; and

4.    Procedures to prevent adverse impact from any accidental or slugload discharge, including, but not limited to, 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, measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.

Where applicable, the SC/SPCC plan shall also conform to guidelines found in 40 CFR, Part 112 and to Ecology’s “Guidelines to Prevent, Control, and Contain Spills from the Bulk Storage of Petroleum Products” (WDOE 83-8), as now or as they may be amended. Each discharger shall complete its SC/SPCC plan and submit it to the wastewater manager within one hundred twenty days of being notified by the manager to do so. The wastewater manager will review the SC/SPCC plan before construction of any prevention facility. No discharger who discharges to the POTW after the aforesaid date shall be permitted to introduce pollutants into the system until such SC/SPCC plan has been reviewed by the wastewater manager. Review of such plan by the wastewater manager shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this chapter.

B.    A discharger who has prepared an SC/SPCC plan shall review and evaluate such plan at least every two years from the date of submittal. As a result of this review and evaluation, the discharger shall amend the SC/SPCC plan within six months of the review to include more effective prevention and control technology if: (1) such technology will significantly reduce the likelihood of a spill event from the facility, and (2) if such technology has been field-proven at the time of the review. The plan shall be maintained on the plant site and readily available to facility personnel.

C.    Dischargers shall verbally notify the wastewater manager immediately upon the occurrence of a slugload or accidental discharge of substances prohibited by this chapter and take immediate action to correct the situation. Within five days after the occurrence of the slugload or accidental discharge, the discharger shall follow up with a written notification to the wastewater division. The notifications shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions taken or to be taken. Any discharger who discharges a slugload of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to any other liabilities established by this chapter or other city ordinance and the amount of any fines, penalties, damages or costs assessed against the city by any state or federal agency, court of law or private individual, as a result of the slugload or accidental discharge.

D.    Signs shall be permanently posted in conspicuous places on discharger’s premises, advising employees whom to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover such a discharge with respect to emergency notification procedures.

E.    Significant industrial users shall verbally notify the wastewater manager immediately of any changes in its facility or operating procedures that will affect its potential for slug discharges. Within five days of its verbal notification, the discharger shall follow up with a written notification to the wastewater division. Changes that will affect a facility’s potential for slug discharges include, but are not limited to, significant changes to the hazardous substances stored at the facility and changes to the discharge practices associated with the facility’s operating procedures. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.090 Pretreatment facilities.

A.    Dischargers shall provide all known, available and reasonable methods of prevention, control and pretreatment as required to comply with this chapter and state and federal regulations, and shall achieve compliance with all applicable pretreatment standards within the time limitations as specified by appropriate statutes, regulations, chapters and ordinances. Where the city deems it necessary, a discharger shall provide, properly operate and maintain, at the discharger’s own cost and expense, facilities required to pretreat wastewater to a level acceptable to the city. When requested to do so, the discharger shall submit detailed plans showing the pretreatment facilities to both the wastewater manager and the code administration and planning manager for review and acceptance before construction of the facility. The review of such plans by either the wastewater manager or the code administration and planning manager shall in no way relieve the discharger from the responsibility of modifying its facility as necessary to produce an effluent acceptable to the wastewater manager under the provisions of this chapter. The discharger shall obtain all necessary construction-operating permits from both the wastewater manager and the code administration and planning manager. Prior to completion of the pretreatment facility, the discharger shall furnish its plan of operations and maintenance procedures for the wastewater manager to review. Such pretreatment facilities shall be under the control and direction of a qualified wastewater treatment operator, as defined in this chapter.

B.    Any subsequent proposal for significant changes in the pretreatment facilities or method of operation shall be reported prior to and be accepted by the wastewater manager prior to the discharger’s initiation of the changes.

C.    Pretreatment facilities shall comply with the applicable requirements of Chapter 173-240 and Section 173-216-110 of the Washington Administrative Code (WAC) and RCW 90.48.010, as now or as they may be amended, and with the accepted plan of operations and maintenance procedures. The city will have the opportunity to audit periodically the compliance of the discharger with all applicable requirements, and to require changes in the discharger’s plan of operations and maintenance procedures in order to ensure the discharger’s continued compliance with these requirements. The discharger shall then comply with the modified plan of operations and maintenance procedures, together with all applicable requirements as may be specified by this chapter and federal and state regulations.

D.    All wastes discharged into the food processing sewer shall be adequately screened by a twenty mesh or finer screen before discharge. An additional screen, with openings not to exceed one-fourth inch square, shall be installed in a fixed position so that all material must pass through said screen immediately before entrance into the sewer.

E.    Grease, oil and sand interceptors shall be provided when, in the opinion of the wastewater manager, they are necessary for the proper handling of liquid wastes containing floatable or emulsified grease, fats or oil in amounts exceeding those specified in YMC 7.65.060(B)(7), or any flammable wastes, sand or other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units. Such interceptors shall be provided within six months of receipt of a written request from the wastewater manager to do so. Dischargers who operate restaurants, cafes, lunch counters, cafeterias, bars or clubs; or hotel, hospital, sanitarium, factory or school kitchens; or other establishments that serve or prepare food where grease may be introduced to the sewer system shall have grease interceptors (grease traps) to prevent the discharge of fat waste, oil or grease. Take-out food establishments or other establishments that prepare food, but do not cook in oil or grease, and who serve food only in disposable containers, may be exempted from this requirement, provided their discharges do not violate YMC 7.65.060 (the general discharge prohibitions) of this chapter. The grease interceptors shall be installed in the waste line leading from sinks, drains or other fixtures where grease may be discharged. All new interceptors requested by the wastewater manager shall be of a type and capacity, conforming to and described in the edition of the Uniform Building Code most recently adopted by the city, and approved by the code administration and planning manager, and shall be located as to be readily accessible for cleaning and inspection. Dischargers must maintain these interceptors in a manner that will always prevent fat waste, oil, grease, flammable wastes, sand or other harmful ingredients from being carried into the sewer system. The owner shall be responsible for the proper removal and disposal by appropriate means of the captured material, and shall maintain records of the dates and means of disposal which are subject to review by the wastewater manager. Any removal and hauling of the collected materials not performed by owner’s personnel must be performed by waste disposal firms currently licensed by the Yakima health district. The collected materials removed from such interceptors shall not be disposed of in sanitary, industrial or storm sewers. Failure to provide or maintain such grease, oil and sand traps in accordance with the provisions of this section shall be a violation of this chapter and subject to the sections set forth in Parts 8 and 9 of this chapter. (Ord. 2003-74 § 1 (part), 2003).

Part 5. Fees

7.65.110 Rates, charges and fees.

Rates, charges and fees relating to the pretreatment program established by this chapter shall be as set forth in Chapter 7.60. (Ord. 2003-74 § 1 (part), 2003).

Part 6. Administration, Reporting and Monitoring

7.65.120 Industrial dischargers.

A.    It is unlawful for any industrial discharger to discharge sewage, industrial wastewater or any other wastes into the city’s POTW except as authorized by the city and by Chapter 173-216 WAC, as now, or as it may be amended.

B.    The city shall have the right to deny or condition new or increased contributions of pollutants, or changes in the nature of pollutants, to the POTW by industrial dischargers where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the POTW to violate its NPDES permit. New sources and new dischargers shall not be allowed to discharge without first complying with the applicable pretreatment standards and requirements. New sources and new dischargers subject to the permitting or authorization requirements of Part 7 of this chapter shall comply with those requirements.

C.    Compliance by existing sources with categorical pretreatment standards shall be within three years of the date the categorical pretreatment standard is effective unless a shorter compliance time is specified in the appropriate subpart of 40 CFR Chapter I, Subchapter N. Direct dischargers with NPDES permits modified or reissued to provide a variance pursuant to Section 301(i)(2) of the Act shall be required to meet compliance dates set in any applicable categorical pretreatment standard. Existing sources which become industrial dischargers subsequent to promulgation of an applicable categorical pretreatment standard shall be considered existing industrial dischargers except where such sources meet the definition of a “new source” within the meaning of this chapter. New sources and new significant industrial dischargers shall install and have in operating condition, and shall start up all pollution control equipment required to meet applicable pretreatment standard before beginning to discharge. Within the shortest feasible time (not to exceed ninety days after the beginning of the discharge), new sources and new significant industrial dischargers must meet all applicable pretreatment standards.

D.    The wastewater manager shall establish a final compliance deadline date for any existing user not covered by an applicable categorical pretreatment standard or for any categorical user when the local limits for said user are more restrictive than the applicable federal categorical pretreatment standard. Any existing industrial discharger that must comply with a more stringent local limit which is in noncompliance with any local limits shall be provided with a compliance schedule placed in a wastewater discharge permit to ensure compliance within the shortest time feasible. (Ord. 2003-74 § 1 (part), 2003).

7.65.130 Industrial discharger identification and data disclosure.

A.    The wastewater manager shall develop and implement procedures to identify all possible industrial dischargers and the character and volume of the discharge from those dischargers. The wastewater manager shall develop, maintain, and report a list of industrial dischargers as required by 40 CFR 403.8(f)(6). As required by 40 CFR 403.8(f)(2)(iii), the wastewater manager shall develop and implement procedures to notify all industrial users of applicable pretreatment standards and requirements.

B.    When requested by the city to do so, industrial dischargers shall complete and file with the wastewater division preliminary or follow-up industrial waste survey (IWS) signed by an authorized representative of the industrial discharger and in the form prescribed by the wastewater division. This industrial waste survey shall be filed within thirty days of being received by the industrial discharger, unless the industrial discharger requests in writing a thirty-day extension from the wastewater manager and the manager approves the request in writing. Failure to complete this survey shall be reasonable grounds for terminating service to the industrial discharger and shall be considered a violation of this chapter. (Ord. 2003-74 § 1 (part), 2003).

7.65.140 Reporting requirements for industrial dischargers.

A.    Within either one hundred eighty days after the effective date of a categorical pretreatment standard, or the final administrative decision on a category determination under 40 CFR 403.6(a)(4), whichever is later, existing significant industrial dischargers subject to such categorical pretreatment standards, and currently discharging to or scheduled to discharge to the POTW, shall be required to submit to the wastewater manager a report which contains the information listed in this section. At least one hundred twenty days prior to commencement of their discharge, new sources, and sources that become significant industrial dischargers subsequent to the promulgation of an applicable categorical standard, shall be required to submit to the wastewater manager a report which contains the information listed in this section. A new source shall also be required to report the method of pretreatment it intends to use to meet applicable pretreatment standards. A new source shall also give estimates of its anticipated flow and quantity of pollutants discharged.

The industrial discharger shall submit the information required by this section including:

1.    The name and address of the facility including the name of the operator and owners.

2.    A list of any environmental control permits held by or for the facility.

3.    A brief description of the nature, average rate of production and standard industrial classifications of the operation(s) carried out by such industrial discharger. This description should include a schematic process diagram, which indicates points of discharge to the POTW from the regulated processes.

4.    Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary, to allow use of the combined waste stream formula set out in 40 CFR 403.6(e).

5.    A measurement of pollutants.

a.    Identification of the categorical pretreatment standards applicable to each regulated process.

b.    Submission of the results of sampling and analysis identifying the nature and concentration (and/or mass, where required by the standard or by the city) of regulated pollutants in the discharge from each regulated process. The industrial discharger shall take a minimum of one representative sample to compile the data necessary to comply with the requirements of this subsection. Instantaneous, daily maximum and long-term average concentrations (or mass, where required) shall be reported. The sample shall be representative of daily operations and shall be analyzed in accordance with procedures set out in subsection H of this section. In cases where the pretreatment standard requires compliance with best management practices or pollution prevention alternatives, the industrial discharger shall submit documentation as required by that standard to document compliance with the standard.

c.    Sampling must be performed in accordance with procedures set out in subsection I of this section.

d.    The city may allow the submission of a baseline report, which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures.

6.    A statement from the industrial discharger’s authorized representative and certified by a professional engineer registered in the state of Washington, indicating whether pretreatment standards are being met on a consistent basis and, if not, whether additional operation and maintenance (O&M) and/or additional pretreatment is required to meet the pretreatment standards and requirements.

7.    If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the industrial discharger will provide such additional pretreatment and/or O&M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. Where the industrial discharger’s categorical pretreatment standard has been modified by a removal allowance (under 40 CFR 403.7), the combined waste stream formula (under 40 CFR 403.6(e)), and/or a fundamentally different factors variance (under 40 CFR 403.13) at the time the industrial discharger submits the report required under subsection A of this section, the information required by subsections (A)(6) and (7) of this section shall pertain to the modified limits. If the categorical pretreatment standard is modified by a removal allowance, the combined waste stream formula, and/or a fundamentally different factors variance after the industrial discharger submits the report required under subsection A of this section, any necessary amendments to the information requested by subsections (A)(6) and (7) of this section shall be submitted by the industrial discharger to the wastewater manager within sixty days after the modified limit is approved.

The following conditions shall apply to the schedule required by this subsection:

a.    The schedule shall contain progress increments in the form of dates for the commencement and completion of major events leading to the installation and operation of additional pretreatment facilities required for the discharger to meet the applicable pretreatment standards (such events include hiring an engineer, completing preliminary and final plans, executing contracts for major components, commencing and completing installation, beginning and conducting routine operation).

No progress increment referred to above shall exceed nine months.

b.    The industrial discharger shall submit a progress report to the wastewater manager no later than fourteen days following each date in the schedule and the final date of compliance including, as a minimum, whether or not the discharger complied with the increment of progress, the reason for any delay, and, if appropriate, the steps being taken by the industrial discharger to return to the established schedule. In no event shall more than nine months elapse between such progress reports to the wastewater manager.

8.    All baseline monitoring reports must be signed and certified in accordance with subsection K of this section.

B.    Within ninety days following the date for final compliance with applicable categorical pretreatment standards (deadline date for categorical dischargers published in the appropriate categorical pretreatment standards, compliance date for noncategorical dischargers established by the city) or in the case of a new source (new discharger) within thirty days of commencement of the introduction of wastewater into the POTW, any industrial discharger subject to such pretreatment standards and requirements shall submit to the wastewater manager a report containing the information described in subsections (A)(4) through (6) of this section. For industrial dischargers which may be subject to equivalent mass or concentration limits established in accordance with the procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the industrial discharger’s long-term wastewater discharge rate. For all other industrial dischargers subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the industrial discharger’s actual wastewater discharge rate during the appropriate corresponding sampling period. All compliance reports must be signed and certified in accordance with subsection K of this section.

C.    Any significant industrial discharger subject to a pretreatment standard shall, at a frequency determined by the wastewater manager in its discharge permit, but in no case less than twice per year, submit a report indicating the nature and concentration of pollutants in the discharge which are limited by such pretreatment standards and the measured or estimated average and maximum daily flows for the reporting period. All compliance reports must be signed and certified in accordance with subsection K of this section.

1.    The report shall include a record of the concentrations (and mass if specified by the city) of the limited pollutants that were measured and a record of all flow measurements (average and maximum) taken at the designated sampling locations, and shall also include any additional information required by this chapter or regulations promulgated thereunder. Production data shall be reported if required by the city. Both daily maximum and average concentration (or mass, where required) shall be reported. In cases where the pretreatment standard requires compliance with best management practices or pollution prevention alternatives, the industrial discharger shall submit documentation as required by that standard to document compliance with the standard. If a discharger sampled more frequently than required by the city, it must submit all results of sampling and analysis of the discharge during the reporting period.

2.    Any industrial discharger subject to equivalent mass or concentration limits established by the city in accordance with procedures provided in 40 CFR 403.6(c) shall submit as part of its report a reasonable measure of the discharger’s long-term production rate.

3.    If the city calculated limits to factor out dilution flows or nonregulated flows, the industrial discharger shall be responsible for providing flows from the regulated process flows, dilution flows and nonregulated flows.

4.    The report shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of the normal work cycles and expected pollutant discharges to the POTW.

5.    Flows shall be reported on the basis of actual measurement; provided, however, that the city may accept reports of average and maximum flows estimated by verifiable techniques if the city determines that an actual measurement is not feasible.

6.    Sampling shall be representative of the industrial discharger’s actual discharge and collected in accordance with subsection I of this section. Wastewater monitoring and flow management facilities shall be properly operated, kept clean and maintained in good working order at all times. The failure of an industrial discharger to keep its monitoring facility in good working order shall not be grounds for the industrial discharger to claim that sample results are unrepresentative of its discharge.

7.    Where the industrial discharger conducts self-monitoring, the number and frequency of monitoring shall be prescribed by the city in their discharge permit. The samples shall be processed at a laboratory accredited by the state. Alternately, at the request of the industrial permittee, the city may collect and analyze the samples as part of the required sampling and analysis under its NPDES permit and YMC 7.65.160(E). All costs associated with such testing and analysis shall be the responsibility of the industrial discharger.

D.    Any industrial discharger subject to this chapter shall report to the wastewater division, in person or by phone, ninety days prior to any changes in its operations or processes which significantly affect its wastewater constituents or characteristics, or storage of chemicals, and which take place after the last report, permit application or environmental survey. These changes include, but are not limited to, flow, BOD, or TSS increases of twenty percent or greater, the commencement of discharge of any prohibited or limited substance under YMC 7.65.060(B), and the addition of any process covered by national categorical pretreatment standards. Formal written notification shall also be made to the wastewater division at least ten days prior to such change.

E.    Any discharger operating under equivalent mass or concentration limits shall notify the wastewater manager within two business days after the discharger has a reasonable basis to know that the production level will significantly change within the next calendar month. Any discharger not notifying the wastewater manager of such an anticipated change shall be required to comply with the existing limits.

F.    All significant industrial dischargers not subject to categorical pretreatment standards and, as deemed necessary by the wastewater manager, any minor industrial dischargers shall provide to the wastewater manager the same reports as set forth in subsection A of this section.

G.    If sampling performed by an industrial discharger indicates a violation, the industrial discharger must notify the wastewater manager within twenty-four hours of becoming aware of the violation. The industrial discharger shall also repeat the sampling and analysis and submit the results of the repeat analysis to the wastewater manager within thirty days after becoming aware of the violation. Where the city has performed the sampling and analysis in lieu of the industrial discharger, the city must perform the repeat sampling and analysis within thirty days after becoming aware of the violation unless it notifies the industrial discharger of the violation and requires that discharger to perform the repeat sampling and analysis. The industrial discharger is not required to resample if the POTW performs monitoring at the industrial discharger’s at least once a month, or if the POTW performs sampling between the industrial discharger’s initial sampling and when the industrial discharger receives the results of this sampling.

H.    All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report, shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and WAC 173-216-125. If 40 CFR Part 136 or WAC 173-216-125 does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by the EPA.

I.    Except as indicated below, the industrial discharger must collect wastewater samples using twenty-four-hour flow proportional composite collection techniques. In the event twenty-four-hour flow proportional composite sampling is infeasible, the wastewater manager may authorize the use of time proportional composite sampling or a minimum of four grab samples where the industrial discharger demonstrates that this will provide a representative sample of the actual effluent being discharged to the POTW and the wastewater manager shall document the decision to allow alternative sampling in the discharger’s facility file. In addition, grab samples may be required to show compliance with instantaneous discharge limits. Samples to be analyzed for fats, oil and grease (FOG), temperature, pH, cyanide, phenols, toxicity, sulfides, metals and volatile organic compounds shall be obtained using grab collection techniques.

1.    Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated or manufacturing process if no pretreatment exists or as determined by the city. For dischargers subject to categorical pretreatment standards, if other wastewaters are mixed with the regulated wastewater prior to pretreatment the discharger should measure the flows and concentrations necessary to allow use of the combined waste stream formula of 40 CFR 403.6(e) in order to evaluate compliance with the applicable pretreatment standards.

2.    All sample results shall indicate the time, date and place of sampling, and methods of analysis, and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges from the industrial discharger. If a discharger subject to the reporting requirements in and of this section monitors any pollutant more frequently than required by the city, it must submit the results of this extra sampling and analysis of the discharge as part of its self-monitoring report.

J.    The wastewater manager may use a wastewater grab sample(s) to determine noncompliance with applicable pretreatment standards.

K.    Any reports required by this chapter and submitted by the industrial discharger shall be signed by an authorized representative of the discharger. Any person signing the report shall make the following certification:

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

L.    Written reports shall be deemed to have been submitted on the date postmarked. For reports, which are not mailed, postage prepaid, into a mail facility serviced by the U.S. Postal Service, the date of receipt of the report shall govern. The wastewater manager shall develop and implement procedures to receive and analyze reports and other notices submitted by industrial dischargers. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.150 Monitoring equipment.

A.    The city may require a discharger to install and operate, at the discharger’s own expense, monitoring equipment to allow inspection, sampling and flow measurement of all discharges into the sewer system, to assure compliance with this chapter. The monitoring equipment shall be situated on the discharger’s premises, except that if such a location would be impractical or cause undue hardship on the discharger, the city may allow such equipment to be installed in an accessible public street or sidewalk area.

B.    There shall be ample room in or near such monitoring equipment to allow accurate wastewater sampling and preparation of samples for analysis by the discharger and the city. The monitoring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the discharger.

C.    All monitoring equipment shall be installed and maintained in accordance with all applicable standards and specifications. All devices used to measure wastewater flow and quality shall be calibrated to ensure their accuracy. (Ord. 2003-74 § 1 (part), 2003).

7.65.160 Inspection and sampling.

A.    To assess compliance with this chapter, independent of any information provided by an industrial discharger, the city shall have the right to inspect, conduct surveillance of, and collect wastewater samples from all monitoring equipment, sewer lines and plant facilities, and to examine and copy any discharge related records, during all hours that a discharger is operating or whenever employees are on the premises. The city will normally schedule such inspections upon seven days’ notice, but, if deemed appropriate or necessary, shall have the right to make unscheduled inspections without prior notice. A permitted or authorized discharger, as a condition of their permit, shall sign a form provided by the city, that allows authorized city employees right of entry to the discharger’s facility to carry out the duties of the wastewater division under this chapter. The city shall have the right to erect or install, on the discharger’s property, such devices as are reasonably necessary to conduct sampling, inspection, compliance monitoring or metering operations. It will be unlawful under this chapter to interfere with any city sampling equipment or samples.

B.    Where an industrial discharger has security measures in force which require proper identification and clearance before entry into its premises, the industrial discharger shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, personnel from the city, state, and EPA will be permitted to enter without delay, for the purposes of performing their specific responsibilities.

C.    Failure to allow inspection, sampling, monitoring, metering or copying as authorized by this section shall be grounds for termination of wastewater treatment services as well as any other enforcement action authorized under this chapter and deemed appropriate by the wastewater manager.

D.    If the wastewater manager has been refused access to a building, structure or property or any part thereof, and if the wastewater manager has demonstrated 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 permit or order issued hereunder, then upon application by the city attorney, judge of a competent jurisdiction will issue a search and/or seizure warrant describing herein the specific location subject to the warrant. The warrant will specify what, if anything, may be searched and/or seized on the property described. Such warrant will be served at reasonable hours by the wastewater manager in the company of an uniformed police officer of the city. In the event of an emergency affecting the public health and safety, inspections will be made without the issuance of a warrant.

E.    The wastewater manager shall develop and implement procedures to randomly sample and analyze the effluent from industrial users and conduct surveillance activities to better identify, independent of information supplied by industrial dischargers, occasional and continuing noncompliance with applicable pretreatment standards. The wastewater manager shall inspect, and collect and analyze effluent samples from each significant industrial discharger at least once per year. The wastewater manager shall investigate instances of noncompliance indicated by information provided by industrial dischargers and by the wastewater manager’s independent inspection, sampling, and analysis. (Ord. 2003-74 § 1 (part), 2003).

7.65.165 Vandalism.

No person shall willfully 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. 2003-74 § 1 (part), 2003).

7.65.170 Confidential information.

A.    Information and data furnished to the city with respect to the nature and frequency of discharge will be available to the public or other governmental agency without restriction unless the discharger specifically requests and is able to demonstrate that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets or proprietary information of the discharger under the laws or regulations of the state or federal government. If a discharger furnishing a report requests that information provided as part of a report be kept confidential, and the discharger marks said pages as “confidential,” then the portions so marked of a report or other information which may disclose trade secrets or secret processes protected by state or federal law, will not be made available for inspection by the public, subject to the provisions of Chapter 42.17 RCW, as now or as it may be amended, but will be made available upon written request to governmental agencies for uses related to this chapter, the NPDES permit, state waste discharge permit and/or the pretreatment programs; provided, however, that such portions of a report or other information will be available for use by the state or any state agency in judicial review or enforcement proceedings involving the discharger furnishing the report. Wastewater constituents and characteristics, other “effluent data” as defined by 40 CFR 2.302, and information for which claims of confidentiality must be denied pursuant to WAC 173-216-080 shall not be recognized as confidential information and shall be available to the public without restriction.

B.    Information accepted by the city as confidential will not be transmitted to any governmental agency or to the general public by the city until and unless a ten-day notification is given to the discharger. Once notice of intent to release information has been given to the discharger, if the discharger fails to contest the release, then any rights created by this section shall be deemed to have been waived. (Ord. 2003-74 § 1 (part), 2003).

Part 7. Wastewater Discharge Permits and Authorizations

7.65.180 Wastewater discharge permit and authorization determination.

A.    All new nonresidential dischargers (domestic and nondomestic) shall submit a completed preliminary industrial waste survey to the wastewater division for its review and determination of whether a wastewater discharge permit or authorization is required. This industrial waste survey shall be filed within thirty days of being received by the industrial discharger, unless the industrial discharger requests in writing a thirty-day extension from the wastewater manager and the manager approves the request in writing. The preliminary industrial waste survey shall be signed by an authorized representative of the nonresidential discharger and in the form prescribed by the wastewater division.

The wastewater manager may require either additional information or a follow-up industrial waste survey (IWS), as described in YMC 7.65.184(B). Should the wastewater manager approve the IWS, it shall satisfy YMC 7.65.184(B)(1) for purposes of applying for a wastewater discharge authorization, if applicable. Existing nonresidential dischargers shall submit a preliminary IWS when requested to do so by the city, (see YMC 7.65.130(B)).

1.    Permit Required. Should the wastewater manager determine that a permit is required, the discharger shall comply with YMC 7.65.185, 7.65.190, and 7.65.195 with respect to such permit.

2.    Authorization Required. Should the wastewater manager determine that a written authorization is required for any nonresidential (domestic or nondomestic) discharge, including a temporary discharge, the wastewater manager shall determine which of the terms and conditions in YMC 7.65.190 and 7.65.195, or any other section of this chapter apply. All wastewater discharge authorizations shall comply with YMC 7.65.184.

When a wastewater discharge authorization is not required it shall not relieve any discharger to the POTW from the requirement to apply all known, available, and reasonable methods to prevent and control waste discharges to the waters of the state, or the requirement to obtain approval of plans and reports for the construction of wastewater facilities, or any other applicable requirement contained in this chapter or state or federal law. Nothing herein shall limit the authority of the city to take enforcement action for any unlawful discharge of waste materials or other violations of this chapter. (Ord. 2003-74 § 1 (part), 2003).

7.65.184 Wastewater discharge authorization required.

A.    Authorizations. The wastewater manager may authorize long-term, short-term or temporary wastewater discharges into the city’s sewer system. All authorized wastewater discharges shall comply with pretreatment standards and regulations (YMC 7.65.060), limitations on wastewater strength (YMC 7.65.070), and protect the POTW from slugload or accidental discharges (YMC 7.65.080). Failure to comply shall subject the discharger to the enforcement provisions of Part 8 of this chapter and all industrial dischargers located outside of the city’s boundaries that receive authorization to discharge from the city shall accept the city’s authority to impose those enforcement provisions as a condition to discharging wastewater into the city’s sewer system. The wastewater manager may condition the authorization as necessary to comply with the provisions of this chapter, and may deny requests under this section on the grounds that the discharge would violate any provision of this chapter.

B.    Discharge Authorization Procedure.

1.    Dischargers must submit a completed industrial waste survey (IWS) to the wastewater manager. The survey shall include a complete written description of the proposed project, including the reason for the discharge, rate and duration of the discharge, a site map and plumbing plan showing the location and method to discharge the wastewater, a legal description of the property, and the name and phone number of a contact person. The survey shall also contain the following:

a.    An analysis of the water to be discharged;

b.    Volume of wastewater for discharge.

2.    The survey shall be signed by an authorized representative of the discharger.

3.    The wastewater manager shall review the survey for completeness and, within thirty days, may return to the applicant any incomplete survey with a request for information necessary to complete the survey. Any survey not so returned shall be deemed complete. If returned, the survey shall not be considered complete unless and until the discharger resubmits the survey with the requested information.

4.    Further information or applications may be requested from the discharger by the wastewater manager to help determine the status of the discharger or to assist in setting the terms and conditions of the authorization.

5.    Authorization Terms and Conditions. A wastewater discharge authorization shall include conditions as are deemed reasonably necessary by the wastewater manager to prevent pass through or interference, protect the quality of POTW’s receiving water body, protect worker health and safety, facilitate biosolids management and beneficial reuse, and protect against damage to the POTW. The wastewater manager may include any requirement of YMC 7.65.195 or any other section of this chapter to achieve these goals.

6.    Notification of a change in the volume or constituents of any authorized discharge shall be made thirty days in advance of the change to provide the wastewater manager time to consider if a new authorization will be required (see YMC 7.65.140(D)). (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.185 Wastewater discharge permit required.

A.    Permit Required of all Significant Industrial Dischargers. On and after the date of full delegation, no significant industrial discharger shall discharge wastewater into the POTW without first obtaining a wastewater discharge permit from the wastewater manager. Any violation of the terms or conditions of a wastewater discharge permit shall be deemed a violation of this chapter. Obtaining a wastewater discharge permit does not relieve a permittee of its obligation to comply with all applicable federal and state standards or with any other applicable requirement of this chapter or federal or state law.

1.    Existing Significant Industrial Dischargers. Any existing significant industrial discharger holding a valid wastewater discharge permit that will expire on or after the date of full delegation shall submit a complete permit application in accordance with YMC 7.65.190 at least ninety days prior to the expiration of the then-existing permit; provided, that if such renewal will involve an increase in volume or a change in the characteristics of discharges beyond those previously authorized, then the industrial discharger shall submit a complete permit application in accordance with YMC 7.65.190 at least one hundred twenty days prior to the expiration of the then-existing permit.

2.    A significant industrial discharger whose existing wastewater discharge permit has expired and who has submitted its reapplication in the time period specified herein shall be deemed to have an effective wastewater discharge permit until the city issues or denies the new wastewater discharge permit. A significant industrial discharger whose permit has expired and who failed to submit its reapplication in the time period specified herein will be deemed to be in violation of this chapter. As of June 15, 2003, any existing significant industrial discharger that does not possess a current, valid wastewater discharge permit (issued either by the city or by Ecology) and that intends to continue such discharge shall immediately submit a complete permit application to the city in accordance with YMC 7.65.190.

3.    New Significant Industrial Dischargers. At least one hundred twenty days prior to the anticipated start-up, any new source which shall become a significant industrial discharger on or after the date of full delegation shall submit a complete permit application in accordance with YMC 7.65.190. Such new source shall not discharge wastewater to the POTW without first receiving a wastewater discharge permit from the city. (Ord. 2003-74 § 1 (part), 2003).

7.65.190 Wastewater discharge permitting process.

A.    Permit Application.

3.    The permittee shall, at all times, be responsible for the proper operation and maintenance of any facilities or systems of control installed by the permittee to achieve compliance with the conditions of the permit. Where design criteria have been established, the permittee shall not permit flow or waste loadings to exceed approved designed criteria or approved additions thereto.

4.    A new application or supplement to the previous application shall be submitted along with required engineering plans and reports, whenever a new or increased discharge or change in the nature of the discharge is anticipated that is not specifically authorized by the current permit. Such application shall be submitted at least sixty days prior to proposed changes.

5.    In the event the permittee is unable to comply with any of the permit terms and conditions due to any cause, the permittee shall:

a.    Immediately take action to stop, contain, and clean up unauthorized discharges or otherwise stop the violation, and correct the problem;

b.    Immediately notify the wastewater division of the failure to comply; and

c.    Submit a detailed written report to the wastewater division within thirty days, unless requested earlier by the wastewater division, describing the nature of the violation, corrective action taken to prevent a recurrence, and any other pertinent information.

B.    Transfer of a Permit.

1.    A permit is automatically transferred to a new owner or operator of the facility if:

a.    A written agreement, signed by the new owner, between the old and new owner or operator, containing a specific date for transfer of permit responsibility, coverage and liability, is submitted to the wastewater division at least sixty days prior to the specified transfer date; and

b.    The wastewater division does not notify the permittee of the need to modify or revoke and reissue the permit.

2.    Unless a permit is automatically transferred according to subsection (B)(1) of this section, a permit may be transferred only if the permit is modified or revoked and reissued to incorporate such other requirements as determined necessary by the wastewater division.

C.    Modification, Suspension, Revocation and Voiding of Permits.

1.    The wastewater division may modify a permit, including the schedule of compliance or other conditions, if it determines good and valid cause exists, which includes, but is not limited to, promulgation or revisions of categorical standards, the issuance of a special order, a change in the POTW, and alterations or additions to the discharger’s discharges.

2.    Any permit issued under this chapter may be suspended or revoked, in whole or in part, by the wastewater division for, but not limited to, the following reasons:

a.    Violation of any permit term or condition;

b.    Obtaining a permit by misrepresentation or failure to fully disclose all relevant facts;

c.    A material change in quantity or type of waste disposal;

d.    Nonpayment of fees associated with the permit;

e.    Failure to notify the city of significant changes to the discharge prior to implementing that change;

f.    Falsifying reports;

g.    Tampering with monitoring equipment;

h.    Intentionally providing nonrepresentative samples;

i.    Refusing to allow the city access to the facility premises and records; or

3.    Wastewater discharge permits shall be voidable upon cessation of operations. All wastewater discharge permits issued to a particular discharger are void upon the issuance of a new discharge permit to that user. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.198 Revision of the wastewater discharge permit program.

The permit program contained in this chapter shall be revised, as necessary and to the satisfaction of Ecology, to conform with any changes in applicable rules and regulations that may be adopted by Ecology or the federal government subsequent to the grant of authority to the city to administer the wastewater discharge permit program. The city shall submit all amendments of implementing ordinances or resolutions to Ecology for approval prior to passage. (Ord. 2003-74 § 1 (part), 2003).

Part 8. Administrative Enforcement

7.65.200 Notification of violation.

Whenever the wastewater manager finds that any discharger has violated or is violating this chapter, or an order issued hereunder, the wastewater manager may serve upon said discharger written notice of the violation. Within ten days of the receipt date of this notice, an explanation of the violation and a plan for the satisfactory correction and prevention thereof, to include specific required actions, shall be submitted to the wastewater manager. Submission of this plan in no way relieves the discharger of liability for any violations occurring before or after receipt of the notice of violation. 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. 2003-74 § 1 (part), 2003).

7.65.210 Consent orders.

A.    The wastewater manager is hereby empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with the discharger responsible for the noncompliance. Such orders will include specific action to be taken by the discharger to correct the noncompliance within a time period also specified by the order. Such schedules may not extend the compliance date beyond applicable federal deadlines. Consent orders shall have the same force and effect as compliance orders issued pursuant to YMC 7.65.220 and shall be judicially enforceable.

B.    Failure to comply with any terms or requirements of a consent order by the discharger shall be an additional and independent basis for termination of wastewater treatment services or for any other enforcement action authorized under this chapter and deemed appropriate by the wastewater manager. (Ord. 2003-74 § 1 (part), 2003).

7.65.220 Compliance orders.

A.    When the wastewater manager finds that a discharger has violated or continues to violate this chapter or any order issued hereunder, he may issue a compliance order to the discharger responsible for the violation directing that, following a specified time period, sewer service shall be discontinued unless adequate treatment facilities, devices or other related appurtenances have been installed and are properly operated and maintained. Compliance orders may also contain such other requirements as might be reasonably necessary and appropriate to address the noncompliance, including the installation of pretreatment technology, additional self-monitoring and management practices designed to minimize the amount of pollutants discharged to the sewer. In establishing the compliance schedule in the compliance order, the wastewater manager will consider applying to the schedule the conditions provided in YMC 7.65.140(A)(7). A compliance order may not extend the deadline for compliance established for a federal pretreatment standard or requirement, nor does a compliance order release the discharger 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 discharger.

B.    Failure to comply with any terms or requirements of a compliance order by the discharger shall be an additional and independent basis for termination of wastewater treatment services or for any other enforcement action authorized under this chapter and deemed appropriate by the wastewater manager. (Ord. 2003-74 § 1 (part), 2003).

7.65.230 Cease and desist orders.

When the wastewater manager finds that a discharger has violated or continues to violate this chapter or any order issued hereunder, the wastewater manager may issue an order to cease and desist all such violations and direct those persons in noncompliance to: (1) comply forthwith; and (2) take such appropriate remedial or preventative action as may be needed to properly address a continuing or threatened violation, including halting operations and terminating the wastewater discharge. Issuance of a cease and desist order shall not be a prerequisite to taking any other action against the discharger. (Ord. 2003-74 § 1 (part), 2003).

7.65.240 Administrative penalties.

Notwithstanding any other section of this chapter, any discharger who is found by the wastewater manager to have violated any provision of this chapter, or orders issued hereunder, shall be penalized in the amount not to exceed one thousand dollars per violation. Each day on which noncompliance shall occur or continue shall be deemed a separate and distinct violation. Such assessments may be added to the discharger’s next scheduled sewer service charge and the wastewater manager shall have such other collection remedies as he has to collect other service charges. Unpaid charges and penalties shall constitute a lien against the individual discharger’s property. Issuance of an administrative penalty shall not be a prerequisite for taking any other action against the discharger. (Ord. 2003-74 § 1 (part), 2003).

7.65.250 Recovery of costs incurred by the city.

Any discharger violating any of the provisions of this chapter who discharges or causes a discharge producing a deposit or obstruction or causes damage to or impairs the city’s POTW shall be liable to the city for any reasonable expense, loss, fines or damage caused by such violation or discharge. The city will bill the discharger for the cost incurred by the city for any cleaning, repair, replacement work or other damages caused by the violation or discharge. Refusal to pay the assessed costs shall constitute a violation of this chapter enforceable under the provisions of Parts 8 and 9 of this chapter. (Ord. 2003-74 § 1 (part), 2003).

7.65.260 Emergency suspension of treatment services.

A.    The wastewater manager may order the suspension of wastewater treatment service after informal notice to the discharger if it appears to the city that an actual or potential discharge: (1) presents or threatens a substantial danger to the health or welfare of persons or to the environment; or (2) threatens to interfere with the operation of the POTW or to violate any pretreatment limits imposed by this chapter.

B.    Any discharger notified of a suspension of the wastewater treatment service shall cease immediately all wastewater discharges. In the event of a discharger’s failure to comply immediately and voluntarily with the suspension order, the wastewater manager will take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage, including, but not limited to, the POTW, its biosolids or receiving waters, or endangerment to the health and welfare of any individuals. The city shall have the right of access onto the discharger’s private property to accomplish such severance of the sewer line. The wastewater manager will allow the discharger to recommence its wastewater discharge when the endangerment has passed, unless the termination proceedings set forth in YMC 7.65.270 are initiated against the discharger.

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

D.    Any discharger whose wastewater treatment service has been suspended pursuant to this section shall have the right to a post-suspension hearing to be conducted in accordance with the procedures set forth in YMC 7.65.280. A discharger which is responsible, in whole or in part, for 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 wastewater manager prior to the date of the post-suspension hearing. (Ord. 2003-74 § 1 (part), 2003).

7.65.270 Termination of treatment services.

A.    The wastewater manager shall have authority to terminate wastewater treatment services for any discharger if it determines that the discharger has:

1.    Failed to accurately report wastewater constituents and characteristics;

2.    Failed to report significant changes in operations or wastewater constituents or characteristics;

3.    Refused reasonable access to the discharger’s premises for purposes of inspection, monitoring or sampling;

4.    Violated any condition of the discharger’s waste discharge permit;

5.    Violated any of the provisions of this chapter; or

6.    Violated any lawful order of the city issued with respect to the chapter.

In the event any discharger declines to allow access to the discharger’s premises for inspection, monitoring, or sampling, the wastewater manager shall not enter such premises without first obtaining a duly issued judicial warrant.

B.    The discharger shall be given written notice of the city’s decision (and basis or bases therefor) to terminate wastewater services and shall have the right to a pretermination hearing in accordance with the provisions of YMC 7.65.280. (Ord. 2003-74 § 1 (part), 2003).

7.65.280 Administrative hearing.

A.    A discharger shall have the right to an administrative hearing to contest the city’s determination: (1) to suspend the discharger’s wastewater services; (2) to terminate the discharger’s wastewater services; (3) to impose administrative penalties against the discharger; (4) to bill the discharger for costs incurred by the city as a result of the discharger’s violation or discharge; or (5) that the discharger has violated a consent, compliance, or cease and desist order.

B.    Any hearing pursuant to this section must be requested by the discharger in writing within fifteen days after the discharger receives notice of the city’s determination. The discharger’s written request for hearing shall be filed with the wastewater manager. Failure to submit a timely notice shall be deemed to be a failure to exhaust administrative remedies and shall preclude any further review. The city will conduct the hearing within twenty days of the receipt of the request (or within five days if the discharger is contesting suspension or termination of wastewater services).

C.    The administrative hearing authorized by this section will be held before the city manager or the city manager’s designee. Formal rules of evidence will not apply but the discharger and the city shall have the right to present witnesses and documentary evidence. The city manager or the city manager’s designee will issue a written decision within ten days of the conclusion of the hearing.

D.    Any discharger requesting a hearing shall have the right to make an electronic or stenographic record of the proceedings. Such record shall be made at the discharger’s expense.

E.    Except as otherwise provided, all decisions by the city manager or city manager’s designee shall be final and conclusive on all parties unless appealed to the city council under YMC 7.65.285. (Ord. 2003-74 § 1 (part), 2003).

7.65.285 Appeal to the city council.

A.    Any decision of the city manager or the city manager’s designee rendered pursuant to YMC 7.65.280 may be reviewed by appeal to the city council. The discharger must file written notice of appeal with the clerk of the city council within fifteen days following notification of such decision or action. Such notice of appeal shall set forth in reasonable detail the action or decision appealed and the discharger’s grounds for reversal or modification thereof. Failure to submit a timely notice shall be deemed to be a failure to exhaust administrative remedies and shall preclude any further review.

B.    Following receipt of such notice, the clerk of the city council will schedule a date for a public meeting by the city council at which time the city council shall consider the appeal. The date of the public meeting should be not later than twenty days following the date the clerk of the city council receives notice of the appeal. The clerk of the city council will mail written notice to all parties of record to apprise them of the meeting date before the city council.

C.    City council review of the facts shall be limited to evidence presented to the city manager or the city manager’s designee. The city council may request additional information or memoranda in order to reach a decision; provided, that all parties of record are given an opportunity to respond to the material provided.

D.    At the public meeting the city council may adopt, amend and adopt, reverse, amend and reverse the findings, conclusions and decision of the city manager or the city manager’s designee or remand the matter to the city manager or the city manager’s designee. (Ord. 2003-74 § 1 (part), 2003).

7.65.290 Judicial review.

A.    The decision of the city council on an appeal of the decision of the city manager or the city manager’s designee shall be final and conclusive unless within twenty days from the date of final action, the discharger files a petition for review in a court of competent jurisdiction in the manner prescribed by law. (Ord. 2003-74 § 1 (part), 2003).

7.65.300 Publication of enforcement actions.

A list of all dischargers that experience a significant violation of applicable pretreatment standards or other pretreatment requirements during the previous twelve months shall be published, at least annually, by the city in the largest local daily newspaper of general circulation. For the purposes of this provision, a violation is a significant violation which meets one or more of the following criteria:

1.    Chronic violations of wastewater discharge limits, defined here as those in which sixty-six percent or more of all of the wastewater measurements taken during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(l) for the same pollutant parameter;

2.    Technical review criteria (TRC) violations, defined here as those in which thirty-three percent or more of all of the wastewater measurements for each pollutant parameter taken during a six-month period equal or exceed the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(l) multiplied by the applicable TRC (TRC=1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH);

3.    Any other discharge violation of a pretreatment standard or requirement, as defined by 40 CFR 403.3(l) (daily maximum, longer-term average, instantaneous limit or narrative standard) that the city determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of the POTW personnel or the general public);

4.    Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or to the environment or has resulted in the city’s exercise of its emergency authority under YMC 7.65.260 to halt or prevent such a discharge;

5.    Failure to meet, within ninety days after the schedule date, a compliance schedule milestone contained in a local control mechanism or enforcement order for starting construction, completing construction or attaining final compliance;

6.    Failure to provide, within forty-five days after the due date, required reports such as baseline monitoring reports, compliance reports, periodic self-monitoring reports and reports on compliance with compliance schedules;

7.    Failure to accurately report noncompliance;

8.    Failure to maintain records of pretreatment facility maintenance, including, but not limited to, cleaning and waste removal dates, and means of disposal of accumulated wastes; or

9.    Any other violation or group of violations which causes the city to expend considerable time or expense in tracking down the source of pollutants detected in the POTW wastewater influent, or which the city determines will adversely affect the operation or implementation of its pretreatment program. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.310 Performance bonds and liability insurance.

The wastewater manager may decline to reinstate wastewater treatment services for any discharger who has had its services suspended or terminated under the provisions of this chapter unless such discharger, at the discretion of the wastewater manager, either: (1) first files with the wastewater manager a satisfactory bond, payable to the POTW, in a sum not to exceed a value determined by the wastewater manager to be necessary to achieve consistent compliance; or (2) first submits proof that it has obtained financial assurances sufficient to restore or repair POTW damage caused by its discharge. (Ord. 2003-74 § 1 (part), 2003).

7.65.320 Operating upsets.

A.    Any discharger that experiences an upset shall inform the wastewater manager of the upset within twenty-four hours of discovering the upset. Where such information is given orally, a written report describing the upset shall be filed with the wastewater manager by the discharger within five days after the discovery. This report shall be based on properly signed, contemporaneous operating logs or other relevant evidence and shall include:

1.    A description of the upset, the cause of the upset and the impact of the upset on the discharger’s compliance with this chapter.

2.    The duration of noncompliance (including exact dates and times) and, if noncompliance is continuing, the time by which the discharger expects to be in compliance.

3.    All steps which have been taken or will be taken to prevent the recurrence of the upset.

4.    Evidence that the facility was at the time being operated in a prudent and workmanlike manner and in compliance with applicable operation and maintenance procedures.

B.    A timely documented and properly verified operating upset shall be an affirmative defense to any enforcement action brought by the city against the discharger for failure to comply with this chapter to the extent that the enforcement action arises out of violations which occurred during the period of upset; provided, however, that such an upset shall not relieve the discharger of any other liability for the upset including, but not limited to, liability for damages sustained by the POTW, the city or third persons. In any enforcement proceeding, the discharger seeking to establish the occurrence of an upset shall have the burden of proof. (Ord. 2003-74 § 1 (part), 2003).

7.65.330 General/specific prohibitions.

A discharger shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibition against interference and pass through found in YMC 7.65.060(B), or with the specific prohibitions found in YMC 7.65.060(B)(2), (7), (8), (10) and (13), if it can prove that it 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 and that either: (1) a local limit exists under YMC 7.65.070(E) for each pollutant discharged and the discharger was in compliance with each limit directly prior to, and during, the pass through or interference, or (2) no local limit exists under YMC 7.65.070(E), but the discharge did not change substantially in nature or constituents from the discharger’s prior discharge when the city was regularly in compliance with its NPDES permit requirements, and in the case of interference, was in compliance with applicable biosolids use or disposal requirements. (Ord. 2003-74 § 1 (part), 2003).

7.65.340 Bypass.

A.    A discharger may allow any bypass to occur which does not cause the pretreatment standards or requirements of YMC 7.65.060 and 7.65.070 to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of subsections B and C of this section.

B.    If a discharger knows in advance of the need for a bypass, it shall submit prior notice to the wastewater manager, at least ten days before the date of the bypass if possible. A discharger shall submit oral notice of an unanticipated bypass that exceeds applicable pretreatment standards to the wastewater manager within twenty-four hours from the time it becomes aware of the bypass. A written submission shall also be provided within five days of the time the industrial discharger becomes aware of the bypass. The written submission 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 wastewater manager may waive the written report on a case-by-case basis if the oral report has been received within twenty-four hours.

C.    Bypass is prohibited, and the city may take enforcement action against a discharger for a bypass, unless:

1.    Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;

2.    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

3.    The discharger submitted notices as required under subsection B of this section.

The wastewater manager may approve an anticipated bypass, after considering its adverse effects, if the wastewater manager determines that it will meet the three conditions listed in this subsection. (Ord. 2003-74 § 1 (part), 2003).

7.65.350 Records retention.

All dischargers subject to this chapter shall retain and preserve for no less than six years any records, books, documents, memoranda, reports, correspondence and any and all summaries thereof, relating to monitoring, sampling and chemical analyses made by or on behalf of a discharger in connection with its discharge. All records which pertain to matters which are the subject of an enforcement action or litigation shall be retained and preserved by the discharger until all enforcement activities have concluded and all periods of limitation with respect to any and all appeals have expired, but in no case less than six years. (Ord. 2003-74 § 1 (part), 2003).

Part 9. Judicial Enforcement

7.65.360 Judicial remedies.

If any person discharges sewage, industrial wastes or other wastes into the city’s wastewater collection or treatment system contrary to the provisions of this chapter or any order issued hereunder, the wastewater manager, through the city attorney, may commence an action for appropriate legal and/or equitable relief in the court having jurisdiction over the matter (the city of Yakima municipal court or the Yakima County superior court). Such judicial action may be in lieu of or in addition to any other administrative enforcement action authorized herein. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.370 Injunctive relief.

Whenever a discharger has violated or continues to violate the provisions of this chapter or order issued hereunder, the wastewater manager, through counsel, may petition the court having jurisdiction over the matter (the city of Yakima municipal court or the Yakima County superior court) for the issuance of a preliminary or permanent injunction or both (as may be appropriate) which restrains or compels the activities on the part of the discharger. The wastewater manager shall have such remedies to collect fees as associated with legal costs as it has to collect other sewer service charges. Such other action as appropriate for legal and/or equitable relief may also be sought by the city. A petition for injunctive relief need not be filed as a prerequisite to taking any other action against a discharger. (Ord. 2007-26 § 1 (part), 2007: Ord. 2003-74 § 1 (part), 2003).

7.65.380 Civil penalties.

A.    Any discharger who has violated or continues to violate an order of the city, or who fails to comply with: (a) any provision of this chapter, or (b) any rule or order of the city, issued pursuant to this chapter, shall be liable to the city for a civil penalty. The amount of such civil penalty shall be up to one thousand dollars per violation, plus actual damages incurred by the POTW. Each day upon which a violation occurs or continues shall constitute a separate violation. Unpaid civil penalties shall constitute a lien against the individual discharger’s property. In addition to the above-described penalty and damages, the wastewater manager may recover reasonable attorney’s fees, court costs and other expenses associated with the enforcement activities, including sampling and monitoring expenses. A discharger’s failure to pay such civil penalties shall be grounds for termination of wastewater services.

B.    The wastewater manager will petition the court to impose, assess and recover such civil penalties. In determining the amount of liability, the court will take into account all relevant circumstances, including, but not limited to, the extent of harm caused by the violation, the magnitude and duration of the violation, any economic benefit gained through the discharger’s violation, corrective actions by the discharger, the compliance history of the discharger, the city’s enforcement response manual (ERP), which provides guidelines for the assessment of monetary penalties, if available, and any other factor as justice requires.

C.    Filing a suit for civil liabilities shall not be a prerequisite for taking any other action against a discharger. (Ord. 2003-74 § 1 (part), 2003).

7.65.390 Falsifying information.

Any person who knowingly makes any false statements, representations or certifications in any application, record, report, plan or other document filed or required to be maintained pursuant to this chapter, or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method required under this chapter (in addition to civil and/or criminal penalties otherwise provided by law) shall, upon conviction, be guilty of a misdemeanor punishable by a fine of not more than one thousand dollars per violation per day plus costs of prosecution or imprisonment not to exceed ninety days or both. (Ord. 2003-74 § 1 (part), 2003).

7.65.400 Criminal penalties.

Any person who willfully, knowingly, recklessly or negligently violates any provision of this chapter through any act or omission shall, upon conviction, be guilty of a gross misdemeanor, punishable by a fine of not more than five thousand dollars or imprisonment not to exceed one year, or by both such fine and imprisonment. Each violation and each day of each violation shall constitute a separate offense. (Ord. 2006-07 § 28, 2006: Ord. 2003-74 § 1 (part), 2003).

7.65.410 Remedies nonexclusive.

The provisions in Parts 8 and 9 of this chapter are not exclusive remedies. The city reserves the right to take any, all, or any combination of these actions against a noncompliant discharger. (Ord. 2003-74 § 1 (part), 2003).

Part 10. Additional Provisions

7.65.420 Septage and liquid waste hauling requirements.

A.    It is unlawful for any person, firm or corporation to engage in the business of cleaning or pumping out private wastewater disposal systems in the city or to remove, transport or dispose of septage from private wastewater disposal systems by transporting the same across or along any of the streets, alleys or public ways of the city without having first complied with the terms of this section. It is unlawful for anyone to discharge any trucked or hauled waste including, but not limited to, septage from private wastewater disposal systems at any location within the city service area, except at discharge points specifically designated by the POTW or which have been approved in writing by the wastewater manager. Anyone discharging any trucked or hauled waste into the city’s wastewater collection or treatment system must comply with the pretreatment standards and requirements set forth in this chapter.

B.    No person, firm or corporation engaged in septage hauling will be allowed to discharge septage into the POTW unless they comply with the following septage hauling requirements:

1.    Hold a valid septage hauling permit from the Yakima health district;

2.    Carry liability insurance of such kind and in such amount as the city may require to protect itself from any loss or damage that may directly or indirectly be occasioned by the discharge of septage into the POTW;

3.    Complete a septage waste manifest (in triplicate) obtained from the wastewater division prior to arrival at the POTW; and

4.    Prevent the commingling of industrial wastewater, process wastewater, biosolids and domestic wastewater. Any wastewater collected from a business or industry must receive a written authorization from the wastewater manager before surcharge into the POTW is allowed. Any wastewater collected from a business or industry must be discharged into the POTW first before wastewater from another business or industry is collected.

C.    The city shall have the right to inspect and sample any trucked or hauled waste before allowing its discharge to the POTW to verify compliance with the provisions of this chapter and any applicable federal or state laws.

D.    The city shall have the right to refuse the discharge of any trucked or hauled waste to the POTW if it determines within its absolute discretion that the discharge of such trucked or hauled waste would not comply with the provisions of this chapter and any applicable federal or state laws.

E.    The discharge of any trucked or hauled waste containing hazardous wastes, as defined under applicable federal and state laws and regulations, to the POTW shall be strictly prohibited.

F.    Failure to comply with the terms of this section shall subject the person, firm or corporation responsible for the failure to the penalties specified in Part 8 of this chapter. (Ord. 2003-74 § 1 (part), 2003).

7.65.430 Regulations.

The wastewater manager will have the authority to promulgate written regulations consistent with this chapter. (Ord. 2003-74 § 1 (part), 2003).

7.65.440 Severability.

The provisions of this chapter are severable, and if any provision of this chapter, or the application of any provision of this chapter to any circumstance is held invalid, the application of such provision to other circumstances, and the remainder of this chapter shall not be affected thereby. (Ord. 2003-74 § 1 (part), 2003).
