6-6-1 PURPOSE AND POLICY:

A.    This chapter sets forth uniform requirements for users of the Garden City sewer collection system and the Boise City publicly owned treatment works (POTW) and enables the city to protect public health and the environment in conformity with all applicable local, state and federal laws including, but not limited to, the Clean Water Act (33 USC 1251 et seq.) and the general pretreatment regulations (40 CFR part 403).

B.    The objectives of this chapter are:

1. To prevent the introduction of pollutants into the POTW which will interfere with the normal operation of the system or contaminate the resulting municipal sludge;

2. To prevent the introduction of pollutants into the POTW which do not receive adequate treatment and which will pass through the system into receiving waters or the atmosphere or otherwise be incompatible with the system;

3. To improve the opportunity to recycle and reclaim wastewater and sludge from the POTW; and

4. To protect the collection system, the public and the personnel operating the POTW.

C.    This chapter provides for the regulation of users of the POTW through the enforcement of administrative regulations. This chapter authorizes the issuance of indirect discharge permits; authorizes monitoring, compliance, and enforcement activities, including recovery of costs relating to industrial user noncompliance; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program described herein. 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 users in proportion to their use of the POTW, which are the subject of separate enactments. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-2 PRETREATMENT PROGRAM ADMINISTRATION:

ENVIRONMENTAL MANAGER:

The individual who is the duly authorized designee of the Garden City public works director and who is responsible for implementing the city’s industrial pretreatment program and ensuring compliance with local, state, and federal pretreatment requirements.

EXISTING SOURCE:

For a CIU, an existing source is any source of discharge, the construction or operation of which commenced prior to the publication by EPA of proposed categorical pretreatment standards, which will be applicable to such source if the standard is thereafter promulgated in accordance with section 307 of the Act.

EXISTING USER:

For noncategorical users, an "existing user" is defined as any user that is discharging wastewater prior to the effective date hereof.

GRAB SAMPLE:

An individual sample collected over a period of time not exceeding fifteen (15) minutes.

INDIRECT DISCHARGE:

INDIRECT DISCHARGE PERMIT (INDUSTRIAL WASTEWATER DISCHARGE PERMIT, DISCHARGE PERMIT):

An authorization or equivalent control document issued by the city to users discharging wastewater to the POTW. The permit may contain appropriate pretreatment standards and requirements as set forth in this chapter.

INDUSTRIAL USER/USER:

A source of indirect discharge of effluent into the POTW by means of pipes, conduits, pumping stations, force mains, constructed drainage ditches, surface water intercepting ditches, and all constructed devices and appliances appurtenant thereto. This term includes federal, state, and local facilities as part of the regulated community, and shall not include "domestic user" as defined herein.

INDUSTRIAL WASTE:

Solid, liquid or gaseous waste resulting from any industrial, manufacturing, trade, or business process or from the development, recovery or processing of natural resources.

INTERFERENCE:

A discharge which alone or in conjunction with a discharge or discharges from other sources, either: a) inhibits or disrupts the POTW, its treatment processes or operations; b) inhibits or disrupts sludge processes, use or disposal; or c) is the cause of a violation of the discharge permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal in compliance with any of the following statutory/regulatory provisions or permits issued thereunder (or more stringent state or local regulations): section 405 of the Clean Water Act, the Solid Waste Disposal Act (SWDA), including title II more commonly referred to as the Resource Conservation and Recovery Act (RCRA), and including state regulations contained in any state sludge management plan prepared pursuant to subtitle D of the SWDA, the Clean Air Act, and the Toxic Substances Control Act.

MAXIMUM ALLOWABLE INDUSTRIAL LOADING (MAIL):

The estimated maximum loading of a pollutant that can be received at the POTW headworks from all permitted industrial users and other controlled sources without causing pass-through or interference.

MINOR INDUSTRIAL USER (MIU):

A nonresidential user, with an indirect discharge to the POTW, that does not meet the criteria of a significant industrial user, but whose operation and discharge may warrant inspection to ensure compliance with discharge prohibitions, pretreatment facility operation, spill prevention measures, required BMPs and pollution prevention assistance.

NEW SOURCE:

A. Any building, structure, facility, or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under section 307(c) of the Act, which will be applicable to such source if such standards are thereafter promulgated in accordance with that section; provided, that:

 

1. The building, structure, facility, or installation is constructed at a site at which no other source is located; or

 

2. The building, structure, facility, or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or

 

3. The building, structure, facility, or installation is constructed for production or wastewater generating processes which are substantially independent of an existing source at the same site. Substantial independence shall be determined by factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source.

 

B. Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility or installation meeting the criteria of subsection A2 or A3 of this definition, but otherwise alters, replaces or adds to existing process or production equipment.

 

C. For purposes of this definition, construction is deemed to commence when:

 

1. The owner or operator of the facility has entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering and design studies do not constitute a contractual obligation herein; or

 

2. The following are begun as part of a continuous on-site construction:

 

a. Any placement, assembly or installation of facilities or equipment; or

 

b. Significant site preparation work, including clearing, excavation or removal of existing buildings, structures or facilities, which is necessary for the placement, assembly or installation of new source facilities or equipment.

NEW USER (NEW DISCHARGER):

A new user is not a new source and is defined as a user that applies to the city for a new building permit or any person or business that occupies an existing building and plans to discharge wastewater to the city’s collection system after the effective date hereof.

NONSIGNIFICANT CATEGORICAL INDUSTRIAL USER:

An industrial user subject to categorical pretreatment standards that never discharges more than one hundred (100) gallons of process wastewater per day.

PASS-THROUGH:

The occurrence of an indirect discharge which exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW’s NPDES permit (including an increase in the magnitude or duration of a violation).

pH:

A measure of the acidity or alkalinity of a substance, expressed in standard units.

POLLUTANT:

Any substance discharged into a POTW or its collection system which is prohibited or limited by sections 6-6-4, 6-6-5, 6-6-6, 6-6-7, and 6-6-9 of this chapter including, but not limited to, sewage, industrial wastes, chemical wastes, biological materials, heat, and excess nutrients.

POTW (PUBLICLY OWNED TREATMENT WORKS):

Any sewage treatment works owned and operated by the city and the sewers and conveyance appurtenances discharging thereto, whether or not owned by the city. The term also means Garden City and/or Boise City.

PRETREATMENT:

The reduction of the amounts of pollutants, the elimination of pollutants or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into a POTW.

PRETREATMENT REQUIREMENT:

Any substantive or procedural requirement related to pretreatment, including categorical pretreatment standards and/or BMPs, imposed on an industrial user.

PRETREATMENT STANDARDS OR STANDARDS:

Prohibited discharge standards, categorical pretreatment standards, and local limits or BMPs established by the city.

SEPTIC TANK WASTE (SEPTAGE):

Any sewage from holding tanks such as vessels, chemical toilets, campers, trailers, and septic tanks.

SEVERE PROPERTY DAMAGE:

Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.

SEWAGE:

Water carried human wastes or a combination of water carried wastes from residences, business buildings, institutions and industrial establishments.

SEWER:

Any pipe, conduit, ditch or other device used to collect and transport sewage from the generating source.

SIGNIFICANT INDUSTRIAL USER (SIU):

Any industrial user of the POTW that:

 

A. Is subject to categorical pretreatment standards under 40 CFR 403.6 and chapter I, subchapter N, or

 

B. Any other industrial user that: discharges an average of twenty-five thousand (25,000) gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling, and boiler blowdown wastewater); or contributes a process waste stream which makes up five percent (5%) or more of the average dry weather hydraulic or organic capacity to the treatment facility receiving the waste; or is designated as such by the city as defined in 40 CFR 403.3(f) on the basis that the industrial user has a reasonable potential, either singly or in combination with other contributing industries, for adversely affecting the POTW’s wastewater collection and treatment system, the quality of sludge, the system’s effluent quality, or air emissions generated by the system or for violating any pretreatment standards or requirements including BMPs and control of slug discharges.

 

C. Upon the subsequent finding that a user, which had met the above criteria, no longer has reasonable potential for adversely affecting the POTW’s operation or for violating any applicable pretreatment standard or requirement, the city may at any time, on its own initiative or in response to a written request from the user and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a SIU.

 

D. Upon a finding that a CIU meets the criteria and all conditions in 40 CFR 403.3(v)(2), the city may designate the user a nonsignificant categorical industrial user.

SIGNIFICANT NONCOMPLIANCE:

For the purposes of this chapter, significant noncompliance shall mean:

 

A. "Chronic violations of wastewater discharge limits", defined here as those in which sixty-six percent (66%) or more of all of the measurements taken for the same pollutant parameter during a six (6) month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined or described in this chapter;

 

B. "Technical review criteria (TRC) violations", defined here as those in which thirty-three percent (33%) or more of wastewater measurements taken for the same pollutant parameter during a six (6) month period equals or exceeds the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined or described in this chapter multiplied by the applicable factor (1.4 for BOD, TSS, fats, oil and grease, and 1.2 for all other pollutants except pH);

 

C. Any other violation of a pretreatment standard or requirement, including instantaneous limits or narrative standard, that the city believes has caused, alone or in combination with other discharges, interference, pass-through, or endangered the health and safety of city personnel or the general public;

 

D. Any discharge of pollutants that has caused imminent endangerment to the public or to the environment, or has resulted in the city’s exercise of its emergency authority to halt or prevent such a discharge;

 

E. Failure to meet, within ninety (90) days of the scheduled date, a compliance schedule milestone contained in an indirect discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;

 

F. Failure to provide within forty-five (45) days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;

 

G. Failure to accurately report noncompliance; or

 

H. Any other violation(s), including a violation of BMPs, which the city determines will adversely affect the operation or implementation of the city’s pretreatment program.

6-6-4: PROHIBITED DISCHARGE STANDARDS:

6-6-4-1 GENERAL PROHIBITIONS:

No user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass-through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other federal, state, or local pretreatment standards or requirements. (Ord. 894-08, 10-13-2008)

6-6-4-2 SPECIFIC DISCHARGE PROHIBITIONS:

A.    No user shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the POTW:

1. Any wastewater having a pH less than five (5) standard units or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system.

2. Any toxic and nontoxic pollutants including oxygen-demanding pollutants (BOD, etc.) and nutrients in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, to constitute a hazard to life or life processes (growth, development, reproduction, etc.), or to exceed the limitations set forth in categorical pretreatment standards.

3. Any liquids, solids or gases which by reason of their nature or quantity are, or may be sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in another way to the POTW or to the operation of the POTW. At no time shall two (2) successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than five percent (5%) nor any single reading over ten percent (10%) of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, sulfides and any other substances which the city deems to be a fire hazard or a hazard to the system.

4. Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed cup flashpoint of less than one hundred forty degrees Fahrenheit (140×F) (60×C) using the test methods specified in 40 CFR 261.

5. Any solid or viscous substances which will or may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater system, such as, but not limited to: grease, garbage with particles greater than one-half inch (1/2") in any dimension, animal guts or tissues, paunch manure, bones, hair, hides, or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent limestone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, wastepaper, wood, plastics, gas, tar, asphalt residues, and residues from refining, or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes.

6. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass-through.

7. Any noxious or malodorous liquid, gases or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.

8. Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems.

9. Any substance which may cause the POTW’s effluent or treatment residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case, shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under section 405 of the act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the solid waste disposal act, the clean air act, the toxic substances control act or state standards applicable to the sludge management method being used.

10. Any substance which will cause the POTW to violate its discharge and/or other disposal system permits, including NPDES, IPDES, and 40 CFR 503 permits.

11. Any substance with objectionable color that is not removed in the treatment process, or that causes or may cause interference with in-line colorimetric analyzers, such as, but not limited to, dye wastes and vegetable tanning solutions.

12. Any wastewater having a temperature which 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 treatment plant which exceeds forty degrees Celsius (40×C) (104×F). If, in the opinion of the city, lower temperatures of such wastes could harm either the sewers, sewage treatment process or equipment; have an adverse effect on the receiving streams or otherwise endanger life, health or property; or constitute a nuisance, the city may prohibit such discharges.

13. Any wastewater at a flow rate and/or pollutant discharge rate which is excessive over a relatively short time period so that there is a treatment process upset and subsequent loss of treatment efficiency.

14. Any wastewater containing any radioactive wastes or isotopes of such half life or concentration as exceed limits established by the city in compliance with applicable state or federal regulations.

15. Any wastewater which causes a hazard to human life or creates a public nuisance.

16. Any wastewater containing detergents, surfactants, or similar substances that may cause excessive foam or bubbles that persist through the POTW to the point of discharge.

B.    Pollutants, substances, or wastewater prohibited by this chapter shall not be processed or stored in such a manner that could result in their discharge to the POTW. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-4-3 PROHIBITIONS ON STORM DRAINAGE AND GROUND WATER:

Stormwater, ground water, rainwater, street drainage, subsurface drainage or yard drainage shall not be discharged through direct or indirect connections to the wastewater collection system unless specifically authorized by the city. The city may approve the discharge of such water only when no reasonable alternative method of disposal and/or treatment is available. If authorization is granted for the discharge of such waters into the sewer, an indirect discharge permit may be issued. The user shall pay all applicable charges and fees and meet such other conditions as required by the city. (Ord. 894-08, 10-13-2008)

6-6-4-4 PROHIBITIONS ON UNPOLLUTED WATER:

Unpolluted water in excess of two thousand (2,000) gallons per day, including, but not limited to, cooling water, process water or blowdown from cooling towers or evaporative coolers shall not be discharged through direct or indirect connection to the sewer unless specifically authorized by the city. The city may approve the discharge of such water only when no reasonable alternative method of disposal and/or treatment is available. If authorization is granted for the discharge of such waters into the sewer, an indirect discharge permit may be issued.

(Ord. 894-08, 10-13-2008)

6-6-7 LOCAL LIMITS:

The city shall from time to time establish quantitative or other limitations where necessary to protect against pass-through and interference and to provide for protection of the POTW, worker safety, public health, or environment.

A.    No user shall discharge, directly or indirectly, any wastewater having a pH less than five (5) standard units or equal to or greater than twelve and one-half (12.5) standard units as measured at the point of discharge into the wastewater collection system or at a point otherwise designated by permit or agreement.

B.    In addition to categorical pretreatment standards referenced in section 6-6-5 of this chapter, no user shall discharge wastewater containing concentrations (and/or mass limitations) of substances in excess of the following:

0.0007 mg/l mercury

[R] mg/l arsenic

[R] mg/l cadmium

[R] mg/l chromium

[R] mg/l copper

[R] mg/l cyanide

[R] mg/l lead

[R] mg/l molybdenum

[R] mg/l nickel

[R] mg/l selenium

[R] mg/l silver

[R] mg/l zinc

[R] mg/l total phenols

[R] mg/l total oil and/or grease

[R] mg/l total suspended solids

[R] mg/l BOD5

    [R] – Reserved for effluent limitation at a future date.

C.    Certain pollutants shall be allocated to users on a case-by-case mass-loading basis to keep the total industrial discharges of such pollutants within the Maximum Allowable Industrial Loading (MAIL), as calculated by the most recent local limits analysis. The following shall be the MAIL (for phosphorus and nitrogen):

836 lbs/day phosphorus (total)

6260 lbs/day total soluble nitrogen (ammonia + nitrate + nitrite).

D.    Where possible and appropriate, the city may establish and implement industry specific BMPs (best management practices) in conjunction with or in lieu of numerical local limits. Such BMPs shall be considered pretreatment standards and are fully enforceable under this chapter.

E.    Based upon assessment of need and on a user specific basis, the city may incorporate pollutant specific BMPs or concentration or mass limits into indirect discharge permits. Wherever a user is subject to both a categorical pretreatment standard and a local limit for a given pollutant, the more stringent limit or pretreatment standard shall apply. (Ord. 894-08, 10-13-2008; amd. Ord. 974-15, 2-23-2015; Ord. 1007-19, 5-28-2019)

6-6-8 SPECIAL AGREEMENTS:

The city reserves the right to enter into special agreements with users setting out special terms under which they may discharge to the POTW. In no case will a special agreement waive compliance with a categorical pretreatment standard or federal pretreatment requirement. However, the user may request a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. They may also request a variance from the categorical pretreatment standard from the approval authority in accordance with 40 CFR 403.13. (Ord. 894-08, 10-13-2008)

6-6-9 DILUTION:

No user shall increase the use of potable or process water or, in any other way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the local limits or the categorical pretreatment standards. The city may impose mass limitations on users that are using dilution to meet the pretreatment standards or requirements of this chapter, or in other cases where the imposition of mass limitations is deemed appropriate by the city. (Ord. 894-08, 10-13-2008)

6-6-10 DEADLINE FOR COMPLIANCE WITH APPLICABLE PRETREATMENT REQUIREMENTS:

A.    Compliance by existing sources covered by categorical pretreatment standards shall be within three (3) years of the date the standard is effective unless a shorter compliance time is specified in the appropriate standard. Garden City shall establish a final compliance deadline date for any existing user not covered by categorical pretreatment standards or for any categorical user when local limits for said user are more restrictive than EPA’s categorical pretreatment standards. New source dischargers and new users are required to comply with applicable pretreatment standards within the shortest feasible time (not to exceed 90 days from the beginning of discharge). New sources and new users shall install and have in operating condition, and shall start up all pollution control equipment required to meet applicable pretreatment standards before beginning to discharge.

B.    Any indirect discharge permit issued to a categorical user shall not contain a compliance date beyond any deadline date established in EPA’s categorical pretreatment standards. Any other existing user or a categorical user that must comply with a more stringent local limit, and is in noncompliance with any local limits, shall be provided with a compliance schedule placed in an indirect discharge permit to ensure compliance within the shortest time feasible. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

A.    Each user shall provide protection from the accidental discharge of prohibited or regulated materials or substances established by this chapter. Where deemed necessary by the city, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the user’s cost and expense. SIUs are required to notify the city immediately of any changes at their facilities affecting potential for a slug load discharge. When required, an accidental spill prevention plan (ASPP) showing facilities and operating procedures to provide this protection shall be submitted to the city for review and approval before construction of the facility or implementation of procedures. Any user required to develop and implement an ASPP shall submit a plan which addresses, at a minimum, the following elements:

1. Description of discharge practices, including nonroutine batch discharges;

2. Description of stored chemicals;

3. Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the standards in sections 6-6-4, 6-6-5, 6-6-6, 6-6-7, and 6-6-9 of this chapter. Accidental spill or slug load notification instructions shall be posted in conspicuous places on the user’s premises advising employees whom to call; and

4. Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are 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 pollutants (including solvents), and/or measures and equipment for emergency response.

B.    Each existing user shall complete and submit its ASPP within sixty (60) days after notification by the city. Each user shall implement its ASPP as submitted after such ASPP has been reviewed and approved by the city. Review and approval of such plans and operating procedures by the city shall not relieve the user from the responsibility to modify its facility as necessary to meet the requirements of this chapter.

C.    Users shall notify the city water renewal facility immediately upon the occurrence of a slug load or accidental discharge of substances prohibited by this chapter. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions. Within five (5) days following an accidental discharge, the user shall submit to the city a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Any user that discharges a slug load of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to the amount of any fines or costs imposed on the city on account thereof under state or federal law.

Within ninety (90) days following the date for final compliance by the user with applicable pretreatment standards and requirements set forth in this chapter or an indirect discharge permit, or within ninety (90) days after commencement of the introduction of wastewater into the POTW by a new user, including new source users, any user when required shall submit to the city a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons. The report shall state whether the applicable pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation, maintenance, and/or pretreatment is necessary to bring the user into compliance with the applicable pretreatment standards or requirements. This statement shall be signed by an "authorized representative of the user" as defined in section 6-6-3 of this chapter. For CIUs, this report shall contain the information outlined in subsections 6-6-15-2A3, A4, A6, and A11 of this chapter. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-19-2 PERIODIC COMPLIANCE REPORTS:

A.    Any user subject to a pretreatment standard set forth in this chapter, after the compliance date of such pretreatment standard, or, in the case of a new user, after commencement of the discharge to the POTW, shall submit to the city at six (6) month intervals as prescribed in the indirect discharge permit, unless required more frequently by the city, a report indicating the nature and concentration of prohibited or regulated substances in the effluent which are limited by the pretreatment standards hereof. In addition, this report shall include a record of all measured or estimated average and maximum daily flows during the reporting period. Flows shall be reported on the basis of actual measurement, provided, however, where cost or feasibility considerations justify, the city may accept reports of average and maximum flows estimated by verifiable techniques. This report shall also include any additional information as may be required by this chapter or the indirect discharge permit, including production data and flow measurements from any dilute or nonregulated waste streams.

B.    Reports of users shall contain all results of sampling and analyses of the discharge, including the flow and the nature and concentration, or production and mass where required by the city. All sample results shall indicate the time, date and place of sampling, and methods of analyses, and shall certify that the discharge sampled is representative of discharges of normal work cycles and expected pollutant discharges from the user. The frequency of monitoring by the user shall be prescribed within the indirect discharge permit. If a user sampled and analyzed more frequently than what was required in its indirect discharge permit, it must submit all results of sampling and analyses of the discharge as part of its self-monitoring report.

C.    If a user has been granted a waiver to forego sampling for one (1) or more constituents required by the user’s categorical pretreatment standards, each periodic compliance report shall include a statement certifying that the level of waived pollutants has not increased in the facility’s discharge per 40 CFR 403.12(e)(2)(v).

D.     If the city has designated a user as an NSCIU, the user is required to submit an annual certification statement as specified in 40 CFR 403.12(q) and include any additional information necessary to support the certification statement.

E.    All users not required to obtain an indirect discharge permit shall provide appropriate reports to the city as may be required. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-19-3 NONCOMPLIANCE NOTIFICATION, RESAMPLING, AND REPORTING:

If sampling performed by a user indicates a violation, the user shall notify the city within twenty four (24) hours of becoming aware of the violation. The user shall also repeat the sampling within five (5) days and submit the results of the repeat analysis to the city within thirty (30) days after becoming aware of the violation, except the user is not required to resample if:

A.    The city performs sampling at the user at a frequency of at least once per month, or

B.    The city performs sampling at the user between the time when the user performs its initial sampling and the time when the user receives the results of this sampling. (Ord. 894-08, 10-13-2008)

6-6-19-4 NOTIFICATION OF SIGNIFICANT PRODUCTION CHANGES:

Any user operating under an indirect discharge permit incorporating equivalent mass or concentration limits shall notify the city within two (2) business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not providing a notice of such anticipated change will be required to comply with the existing limits contained in its indirect discharge permit. (Ord. 894-08, 10-13-2008)

6-6-19-5 HAZARDOUS WASTE NOTIFICATION:

A.    Any user that is discharging more than fifteen kilograms (15 kg) of hazardous wastes as defined in 40 CFR 261 (listed or characteristic wastes) in a calendar month or any facility discharging any amount of acutely hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e) is required to provide a one-time notification in writing to the city, EPA regional waste management division director, and Idaho division of environmental quality. Any existing user exempt from this notification shall comply with the requirements contained herein within thirty (30) days of becoming aware of a discharge of fifteen kilograms (15 kg) of hazardous wastes in a calendar month or the discharge of acutely hazardous wastes to the city sewer system. Such notification shall include:

1. The name of the hazardous waste as set forth in 40 CFR part 261;

2. The EPA hazardous waste number; and

3. The type of discharge (continuous, batch, or other).

4. If an industrial user discharges more than one hundred kilograms (100 kg) of such waste per calendar month to the sewer system, the notification shall also contain the following information to the extent it is known or readily available to the industrial user:

a. An identification of the hazardous constituents contained in the wastes,

b. An estimation of the mass and concentration of such constituents in the waste streams discharged during that calendar month, and

c. An estimation of the mass of constituents in the waste streams expected to be discharged during the following twelve (12) months.

B.    These notification requirements do not apply to pollutants already reported under the self-monitoring requirements. Whenever the EPA publishes final rules identifying additional hazardous wastes or new characteristics of hazardous waste, a user shall notify the city of the discharge of such a substance within ninety (90) days of the effective date of such regulations. In the case of any notification made pursuant to this section, an industrial user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-19-6 NOTICE OF POTENTIAL PROBLEMS, INCLUDING ACCIDENTAL SPILLS AND SLUG LOADS:

Any user shall notify the city immediately of all discharges that could cause problems to the POTW, including any slug loads, as defined in section 6-6-3 of this chapter. The notification shall include the concentration and volume and corrective action. Steps being taken to reduce any adverse impact should also be noted during the notification. Any user that discharges a slug of pollutants shall be liable for any expense, loss, or damage to the POTW, in addition to the amount of any fines imposed on the city under state or federal law. (Ord. 894-08, 10-13-2008)

6-6-19-7 NOTIFICATION OF CHANGED DISCHARGE:

All users shall promptly notify the city in advance of any substantial change in the volume or character of pollutants in their discharge, including significant manufacturing process changes, pretreatment modifications, and the listed or characteristic hazardous wastes for which the user has submitted initial notification under section 6-6-19-5 of this chapter. (Ord. 894-08, 10-13-2008)

6-6-20: ANALYTICAL AND SAMPLING TECHNIQUES:

6-6-20-1 ANALYTICAL REQUIREMENTS:

All pollutant analyses, including sampling techniques, whether performed by the user, an independent contractor, or the city, shall be performed in accordance with the techniques prescribed in 40 CFR part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. Where 40 CFR part 136 does not include a sampling or analytical technique for the pollutant in question, sampling and analyses shall be performed in accordance with sampling and analytical procedures approved by the administrator of the U.S. EPA. (Ord. 894-08, 10-13-2008)

6-6-20-2 SAMPLE COLLECTION:

A.    Except as indicated in subsection B of this section, the user must collect wastewater samples using flow proportional composite collection techniques. The city may authorize the use of time proportional sampling or the appropriate minimum number of grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.

B.    Unless otherwise prescribed by the city, samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques. Except for temperature and pH, multiple grab samples collected during a twenty-four (24) hour period may be composited prior to analysis.

C.    Samples shall be collected 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 and contained in the user’s indirect discharge permit. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-21 MONITORING FACILITIES:

A.    When required, each user shall provide and operate, at the user’s own expense, a monitoring facility to allow inspection, sampling and flow measurement of each sewer discharge to the city. Each monitoring facility shall be situated on the user’s premises, except where such a location would be impractical or cause undue hardship on the user. The city may concur with the facility being constructed in the public street or sidewalk area providing that the facility is located so that it will not be obstructed by landscaping or parked vehicles. There shall be ample room in or near such sampling facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user. Where required by federal, state, or local regulations, such monitoring facilities shall be provided at the end of a process or production unit, or following treatment of a particular process or production unit, from which regulated toxic pollutants are discharged.

B.    All monitoring facilities shall be constructed and maintained in accordance with all applicable construction standards and specifications. Construction shall be completed within one hundred twenty (120) days (or such longer period as may be allowed by the city) of receipt by the user of the indirect discharge permit. (Ord. 894-08, 10-13-2008)

6-6-22: INSPECTION AND SAMPLING:

6-6-22-1 RIGHT TO ENTER:

The city shall have the right to enter the facilities of any user to ascertain whether the purpose of this chapter, and any indirect discharge permit or order issued hereunder, is being met and whether the user is complying with all requirements thereof. The user shall allow the city or its representatives, upon presentation of credentials of identification, to enter upon the premises of the user at all reasonable hours, including all hours of operation or discharging for the purposes of inspection, sampling or records examination. The city shall have the right to set up on the user’s property, or require installation of, such devices as are necessary to conduct flow monitoring and sampling of the user’s operations. (Ord. 894-08, 10-13-2008)

6-6-22-2 USER SECURITY:

Where a user has security measures in force which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security personnel so that, upon presentation of suitable identification, city staff will be permitted to enter without delay for the purposes of performing specific responsibilities. (Ord. 894-08, 10-13-2008)

6-6-22-3 RIGHT TO SAFE AND READY ACCESS:

The city shall have safe and ready access to all parts of the premises for the purposes of inspection, sampling, records examination and copying, and performance of any additional duties. Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the user at the written or verbal request of the city and shall not be replaced. The costs of clearing such access shall be borne by the user. Unreasonable delays in allowing the city safe access to the user’s premises shall constitute a violation of this chapter. (Ord. 894-08, 10-13-2008)

6-6-22-4 SEARCH WARRANTS:

If the city is refused access to a building, structure, or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this chapter, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program designed to verify compliance with this chapter or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the city shall seek issuance of a search warrant from the district court in the fourth judicial district of Idaho. (Ord. 894-08, 10-13-2008)

6-6-23 CONFIDENTIAL INFORMATION:

Information and data on a user obtained from data disclosure forms, reports, surveys, indirect discharge permits, and monitoring programs, and from city inspection and sampling activities, shall be available to the public or other governmental agency without restriction unless the user specifically requests, and is able to demonstrate to the satisfaction of the city, that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets under applicable state law. When requested and demonstrated by the user that the information furnished be kept confidential, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available immediately upon request to governmental agencies for uses related to the NPDES program or pretreatment program, and in enforcement proceedings involving the user furnishing the information. Wastewater constituents and characteristics and other "effluent data" as defined by 40 CFR 2.302 will not be recognized as confidential information and will be available to the public without restriction. Any such claim must be asserted at the time of submission by clearly indicating the words "confidential business information" on each page containing such information. If no claim is made at the time of submission, all information will be available to the public. All alleged confidential business information is still subject to a valid public records request, pursuant to Idaho Code Title 74, Chapter 1. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-24: ADMINISTRATIVE ENFORCEMENT REMEDIES:

6-6-24-1 USER PROHIBITED CONDUCT:

A user shall not: a) fail to report accurately the wastewater constituents and characteristics of its discharge; b) fail to report significant changes in wastewater constituents or characteristics; c) refuse reasonable access to the user’s premises by representatives of the city for the purpose of inspection or monitoring; or d) violate any state or federal pretreatment regulation, the provisions of the indirect discharge permit, the provisions of this chapter or any order of the city with respect thereto. The city may seek any or all of the remedies or penalties provided in this chapter (including termination of wastewater treatment service) against any user that violates any of the foregoing prohibitions. The city may seek the issuance of a temporary or permanent injunction, as deemed appropriate, for legal and/or equitable relief. Enforcement of pretreatment violations will generally be in accordance with Boise City’s pretreatment program enforcement response plan. The city reserves the right, however, to take other action against any user when the circumstances warrant. Further, Garden City is empowered to take more than one enforcement action against any noncompliant user. These actions may be taken concurrently. Issuance of a compliance order, administrative fines, penalties, and/or cease and desist orders shall not be a bar against, or prerequisite for, taking any other action against a noncompliant user. (Ord. 894-08, 10-13-2008)

6-6-24-2 NOTIFICATION OF VIOLATION; ADMINISTRATIVE ADJUSTMENT:

Whenever the city finds that any user has violated the prohibitions in section 6-6-24-1 of this chapter, the city shall cause to be served upon such user a written notice either in person or by certified or registered mail, return receipt requested, stating the nature of the alleged violation or violations. The notice may also state what fine, penalty or other remedy the city will seek against the user for such alleged violation or violations. Within twenty (20) days of the date of receipt of the notice, the user shall respond personally or in writing to the city advising of its position with respect to the allegations. Thereafter, the user shall be given the opportunity to meet with representatives, employees or agents of the city to discuss the veracity of the allegations, to establish a plan for the satisfactory correction of the violations and preclusion of a recurrence thereof, and to pay the fine or otherwise comply with the penalty or remedy being sought by the city for the violation or violations. Submission of a response in no way relieves the user of liability for any violations occurring before or after receipt of written notice of noncompliance from the city. 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. 894-08, 10-13-2008)

6-6-24-3 RECOVERY OF COSTS:

Any user that violates any of the provisions of this chapter or that discharges or causes a discharge producing a deposit or obstruction or causes damage to or impairs the Garden City’s sewer collection system or the Boise City POTW shall be liable to Garden City or Boise City for any expense, loss or damage caused by such violation or discharge. The city shall charge the user in accordance with the utility billing policy for all enforcement activities, but not limited to additional charges for the cost incurred by the city for any monitoring, surveillance, cleaning, repair or replacement work caused by the violation or discharge, and for costs incurred by the city in investigating the violation and in enforcing this chapter against the user including reasonable administrative costs, fees for testing, attorney fees, court costs and all expenses of litigation. The "utility billing policy," environmental fine and cost recovery schedule in no way relieves the industrial user from additional fines or cost recovery as deemed necessary by the city of Garden City. Refusal to pay the assessed costs shall constitute a violation of this chapter, enforceable under the provisions of this section 6-6-24 and section 6-6-25 of this chapter. Any user that violates any of the provisions of this chapter or that discharges or causes a discharge producing a deposit or obstruction or causes damage to any property may be liable for any expense, loss, or damage caused by such violation. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-24-4 SHOW CAUSE HEARING:

Where the violation of section 6-6-24-1 of this chapter is not corrected by timely compliance through the administrative adjustment procedure set forth in section 6-6-24-2 of this chapter, the city may order any user that suffers or permits a violation of section 6-6-24-1 of this chapter, to show cause before the Garden City council why the proposed enforcement action (which may include suspension of service) should not be taken. A written notice shall be served on the user by personal service or by certified or registered mail, return receipt requested, specifying the time and place of a hearing to be held by the Garden City council regarding the violation, the reasons why the enforcement action is to be taken, the proposed enforcement action and directing the user to show cause before the council why the proposed enforcement action should not be taken. The notice of the hearing shall be served no less than ten (10) days before the hearing. Service of the notice may be made on any agent, officer or authorized representative of a user. The information and evidence presented at the hearing shall be considered by the council, who shall then enter appropriate findings of fact, conclusions of law, and orders with respect to the alleged violations of the user. A show cause hearing shall not be a bar against, or prerequisite for, taking any other action against a noncompliant user. (Ord. 894-08, 10-13-2008)

6-6-24-5 ADMINISTRATIVE FINES:

When the city finds that a user has violated or continues to violate any provision of this chapter, an indirect discharge permit or order issued hereunder, or any other pretreatment standard or requirement, the city may fine such user in an amount not to exceed one thousand dollars ($1,000.00). Such fines shall be assessed on a per violation, per day basis. In the case of monthly or other long term average discharge limits, fines may be assessed for each day during the period of violation. Issuance of an administrative fine shall not be a bar against, or a prerequisite for, taking any other action against the user. (Ord. 894-08, 10-13-2008)

6-6-24-6 ADMINISTRATIVE ORDERS; CONSENT, COMPLIANCE, AND CEASE AND DESIST:

A.    The city may enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with any user responsible for noncompliance. Such documents will include specific action to be taken by the user to correct the noncompliance within a time period specified by the document. Such documents shall have the same force and effect as the administrative orders issued pursuant to subsections B1 and B2 of this section and shall be judicially enforceable. Use of a consent order shall not be a bar against, or prerequisite for, taking any other action against the user.

B.    When the city finds that a user has violated or continues to violate any provision of this chapter, a wastewater discharge permit or order issued hereunder, or any other pretreatment standard or requirement, the city may:

1. Issue a compliance order to the user responsible for the discharge directing that the user come into compliance within a time specified in the order. If the user does not come into compliance within the time specified in the order, sewer service may be discontinued unless adequate treatment facilities, devices, or other related appurtenances are installed and properly operated. Compliance orders may also contain other requirements to address the noncompliance, including additional self-monitoring, and management practices designed to minimize the amount of pollutants discharged to the sewer; or

2. Issue a cease and desist order to the user directing it to cease and desist all such violations and directing the user to:

a. Immediately comply with all requirements; and

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

C.    Issuance of an administrative order shall not be a bar against, or a prerequisite for, taking any other action against the user. (Ord. 894-08, 10-13-2008)

6-6-24-7 EMERGENCY SUSPENSION OF SERVICE AND REVOCATION OF INDIRECT DISCHARGE PERMIT:

The city may, after informal notice to the user in writing or in person or by telephone, revoke the indirect discharge permit and order the suspension of the wastewater treatment service to a user when a user fails to comply with an administrative order issued pursuant to section 6-6-24-6 of this chapter, or it appears to the city that an actual or threatened discharge: a) presents or threatens an imminent or substantial danger to the health or welfare of persons or substantial danger to the environment or b) threatens to interfere with the operation of the sewer collection system or the Boise City POTW. Any user notified of the city’s suspension order shall immediately cease all discharges. In the event of failure of the user to comply with the suspension order, the city may immediately take all necessary steps to halt or prevent any further discharge by such user into the POTW. The city shall have authority to physically cap, block or seal the user’s sewer line (whether on public or private property) in order to terminate service under this section. The city shall have the right to enter upon the user’s property to accomplish the capping, blocking or sealing of the user’s sewer line. The city shall reinstate the wastewater treatment service upon clear and convincing proof by the user of the elimination of the noncomplying discharge or condition creating the threat as set forth above. (Ord. 894-08, 10-13-2008)

6-6-24-8 ANNUAL PUBLICATION:

The city shall publish annually, in a newspaper(s) of general circulation that provides meaningful public notice within the city’s jurisdiction, a list of those users which, during the previous twelve (12) months, were in significant noncompliance with applicable pretreatment standards or other pretreatment requirements. (Ord. 894-08, 10-13-2008)

6-6-25: JUDICIAL ENFORCEMENT REMEDIES:

Civil and criminal penalties listed in this section are per Idaho Code 50-302. (Ord. 1007-19, 5-28-2019)

6-6-25-1 CIVIL PENALTIES:

Any user that violates an order of the city, or that fails to comply with: a) any provision of this chapter or b) any regulation, rule or permit 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 not more than one thousand dollars ($1,000.00) per violation. Each day upon which a violation occurs or continues shall constitute a separate violation. In the case of a monthly or other long term average limit, penalties shall accrue for each day during the period of the violation. Such penalties may be recovered by judicial actions commenced by the city as provided in section 6-6-25-2 of this chapter. In addition, the city may commence an action to terminate the user’s wastewater treatment service. (Ord. 894-08, 10-13-2008)

6-6-25-2 INJUNCTIVE RELIEF:

When the city finds that a user has violated or continues to violate any provision of this chapter, an indirect discharge permit, or order issued hereunder, or any other pretreatment standard or requirement, the city may petition the district court in the fourth judicial district of Idaho for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the indirect discharge permit, order, or other requirement imposed by this chapter on activities of the user. The city may also seek such other action as is appropriate for legal and/or equitable relief. A petition for injunctive relief shall not be a bar against, or a prerequisite for, taking any other action against a user. (Ord. 894-08, 10-13-2008)

6-6-25-3 CRIMINAL PROSECUTION:

A.    Any user that wilfully or negligently violates any provision of this chapter, an indirect discharge permit, or order issued hereunder, or any other pretreatment standard or requirement shall, upon conviction, be guilty of a misdemeanor. Such a misdemeanor offense shall have a maximum punishment of a fine of not more than one thousand dollars ($1,000) or by imprisonment not to exceed six (6) months, or by both such fine and imprisonment. A separate misdemeanor violation is committed on a per day basis.

B.    Any user that wilfully or negligently introduces any substance into the POTW which causes personal injury or property damage shall, upon conviction, be guilty of a misdemeanor and be subject to a penalty and/or imprisonment to the maximum extent allowable under state law. This penalty shall be in addition to any other cause of action for personal injury or property damage available under state law.

C.    Any user that knowingly makes any false statements, representations, or certifications in any application, record, report, plan, or other documentation filed, or required to be maintained, pursuant to this chapter, an indirect discharge permit, or order issued hereunder, or that falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under this chapter shall, upon conviction, be guilty of a misdemeanor, punishable by fines and/or imprisonment to the maximum extent allowable under state law. (Ord. 894-08, 10-13-2008; amd. Ord. 1007-19, 5-28-2019)

6-6-26: AFFIRMATIVE DEFENSES TO DISCHARGE VIOLATIONS:

6-6-26-1 OPERATING UPSETS:

A.    Any user that experiences an upset in operations which places the user in a temporary state of noncompliance with this chapter shall inform the city thereof within twenty four (24) hours of first awareness of the commencement of the upset. Where such information is given orally, a written follow up report thereof shall be filed by the user with the city within five (5) days. An upset shall constitute an affirmative defense to an action brought for noncompliance with applicable pretreatment standards if certain conditions are met. The user that wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:

1. An upset occurred and the user can identify the cause(s) of the upset;

2. The facility was at the time being operated in a prudent and workmanlike manner and in compliance with applicable operation and maintenance procedures; and

3. The user has submitted the following information to the city within twenty four (24) hours of becoming aware of the upset (if this information is provided orally, a written submission must be provided within 5 days):

a. Description of the upset, the cause thereof and the upset’s impact on the user’s compliance status.

b. Duration of noncompliance and, if the noncompliance continues, the time by which compliance is reasonably expected to occur.

c. All steps taken or to be taken to reduce, eliminate and prevent recurrence of such an upset or other conditions of noncompliance.

B.    In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof. Users will have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for noncompliance with applicable pretreatment standards.

C.    Users shall control production of all discharges to the extent necessary to maintain compliance with applicable pretreatment standards upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost, or fails. (Ord. 894-08, 10-13-2008)

6-6-26-2 PROHIBITED DISCHARGE STANDARDS:

A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the prohibitions in section 6-6-4-1, and subsections 6-6-4-2A2, A5, A6, A8, and A12 of this chapter 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: a) a local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass-through or interference; or b) no local limit exists, but the discharge did not change substantially in nature or constituents from the user’s prior discharge when the POTW was regularly in compliance with its NPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements. (Ord. 894-08, 10-13-2008)

6-6-26-3 BYPASS PROVISION:

A.    Users may allow any bypass to occur which does not cause applicable pretreatment standards or requirements to be violated, but only if it is also for essential maintenance to assure efficient operation. These bypasses are not subject to the following:

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

2. A user shall submit oral notice of an unanticipated bypass that exceeds applicable pretreatment standards to the city within twenty four (24) hours from the time the user becomes aware of the bypass. A written submission shall also be provided within five (5) days of the time the user becomes aware of the bypass. The written description shall contain:

a. Description of the bypass and its cause.

b. Duration of the bypass, including the exact dates and times, and if the bypass has not been corrected, the anticipated time it is expected to continue.

c. All steps taken or planned to reduce, eliminate and prevent recurrence of the bypass.

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

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

b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup 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 preventative maintenance; and

c. The user submitted notices as required under subsections A1 and A2 of this section.

B.    The city may approve an anticipated bypass, after considering its adverse effects, if the city determines that it will meet the three (3) conditions listed in subsection A3 of this section. (Ord. 894-08, 10-13-2008)
