[Ord. No. 45-1999, § 700.1, 2-1-2000]
(a) 
The City, at its sole discretion, may elect to allow an industrial or unusual waste producer to utilize the sewage works, provided that it can be demonstrated by the producer to the City's reasonable satisfaction that acceptance of the waste will result in:
(1) 
No violation of applicable federal or state regulations, including federal Environmental Protection Agency pretreatment requirements.
(2) 
No inhibition of, or damage to, the treatment plant's processes or equipment and no upsets of the plant's processes which lead to nuisance conditions, operational problems, or discharge license noncompliance.
(3) 
No pass-through of any waste material not treatable in the City's treatment plant to the receiving waters.
(4) 
No contamination of the City's sewage sludge with toxic or undesirable waste constituents and no impairment of the City's ability to dispose of the treatment plant's sludge residuals.
(5) 
No creation of hazardous or unsafe conditions in the sewer system or treatment plant which might jeopardize the health and welfare of the general public or the City's staff.
(6) 
Equitable allocation of sewer user fees such that the true cost of treating the industrial or unusual waste is fully borne by the sewer user that generated the wastes.
(b) 
Prior to accepting the waste, the City may require that appropriate industrial or unusual wastes undergo pretreatment or flow equalization prior to its discharge into the City's sewer system.
[Ord. No. 45-1999, § 700.3, 2-1-2000]
When required by the City, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control structure in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the City. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
[Ord. No. 45-1999, § 700.4, 2-1-2000]
No discharger or user shall increase the use of potable or process water, in any way, 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 article. Pollutants, substances or wastewater prohibited by this article shall not be processed or stored in a manner that would allow them to be discharged to the treatment plant.
[Ord. No. 45-1999, § 700.5, 2-1-2000]
(a) 
Grease, oil, and sand interceptors shall be provided by the producer when the limits in this article for those substances are exceeded or when, in the opinion of the City, they are necessary for the proper handling of wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity required by the state plumbing code and as required for subsurface wastewater disposal systems and shall be approved by the City prior to installation, and shall be located so as to be readily and easily accessible for cleaning and inspection.

Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation at all times and shall be readily accessible and open to inspection by the City at any time. A maintenance record shall be maintained by the owner for the City's periodic review.
[Ord. No. 45-1999, § 700.7, 2-1-2000]
The categorical pretreatment standards found at 40 CFR chapter I, subchapter N, parts 405 through 471, as from time to time amended, are incorporated in this article by reference. These standards must be adhered to by dischargers to, or users of, the City's sewage works.
[Ord. No. 45-1999, § 700.8, 2-1-2000]
Local limits for certain pollutants may be established by the City to protect against passthrough, interference, process inhibition and damage, safety concerns, and sludge residual contamination. No person shall discharge wastewater containing in excess of the instantaneous maximum allowable discharge limits as identified in this article or on the user's wastewater discharge permit. All discharge limits shall be technically based and approved by the appropriate regulatory agencies.
[Ord. No. 45-1999, § 700.9, 2-1-2000]
When requested by the City, users must complete a wastewater survey form, on a form supplied by the City, which contains information on the nature and characteristics of their wastes. This form must be submitted to the City prior to the discharge of the user's wastewater into the City's sewage works. The City is authorized to prepare a form for this purpose and may periodically require users to update the survey. Failure to complete this wastewater survey form shall be reasonable grounds for terminating service to the user and shall be considered a violation of this article. Existing industrial dischargers shall file wastewater survey forms within 30 days after being notified by the City, and proposed new dischargers shall file such forms at least 90 days prior to connecting to the sewage works. The form shall include, but not be limited to, the following information:

[Ord. No. 45-1999, § 700.11, 2-1-2000]
The City will evaluate the completed wastewater survey forms and material safety data furnished by the user and may require the user to furnish additional information. The user shall provide all requested additional information within 15 days after receiving notification from the City that additional information is required. After full evaluation and acceptance of all submitted data, the City shall make the determination as to whether the user is subject to pretreatment requirements. If the City determines that the user is subject to pretreatment requirements, the City shall require the user to apply for a wastewater discharge permit as required by this division. The user shall make application for a wastewater discharge permit, on a form provided by the City, within 30 days after having received notification from the City to do so. The user shall provide with the permit application, at the user's own expense, the results of all sampling and analysis of the user's wastewater effluent as the City may require to accompany the permit application. If so requested by the City, the user shall collect all required samples in the presence of the City.
[Ord. No. 45-1999, §§ 700.12-700.20, 2-1-2000]
(a) 
Every new or existing user of the City's sewage works who is determined to be a categorical user or significant industrial user is required to obtain a wastewater discharge permit from the City.
(b) 
Wastewater discharge permits shall include such conditions as are reasonably deemed necessary by the City to prevent waste pass-through or interference, protect the quality of the water body receiving the treatment plant's effluent, protect worker health and safety, facilitate sludge management and disposal, and protect against damage to the sewage works. Wastewater discharge permits may impose effluent restrictions or limits on the user if the City determines that such limits are necessary to protect the quality of the treatment plant influent, effluent, or sludge, or to maintain compliance with any applicable federal or state law, including requirements under the City's NPDES permit and national categorical pretreatment standards for new and existing sources set forth in 40 CFR chapter I, subchapter N, parts 401 through 471.
(c) 
Wastewater discharge permits shall be issued for a specified time period, not to exceed five years. A wastewater discharge permit may be issued for a period of less than five years. Each wastewater discharge permit shall indicate a specific date upon which it will expire, and no permit shall run beyond the expiration of the City's NPDES permit. Such discharge permit may, after written notice and hearings, be suspended or revoked by the City council for violation of the permit or change of law applicable to the subject matter of the permit.
(d) 
Wastewater discharge permits shall be issued to a specific operation. A wastewater discharge permit shall not be reassigned or transferred or sold to a new owner or a new user, different premises, or a new or changed operation. To facilitate the issuance of new, separate permits, the City may allow new owners or individuals to operate under an existing wastewater discharge permit for a period not to exceed 90 days.
(e) 
Wastewater discharge permits may contain requirements and compliance schedules for the installation of pretreatment technology, pollution control, or construction of appropriate containment devices, any of which would be designed to reduce, eliminate, or prevent the introduction of pollutants into the City's sewage works.
(f) 
Wastewater discharge permits may contain requirements for the development and implementation of spill control plans or other special conditions, including management practices necessary to adequately prevent accidental, unanticipated, or routine discharges to the City's sewage works.
(g) 
Wastewater discharge permits may contain requirements for the installation and maintenance of inspection and sampling facilities and equipment and for the reporting of all results to the City.
(h) 
The City, for good cause, may, at any time, modify any wastewater discharge permit so long as the public health and safety are maintained.
(i) 
Seven days' advance written notice of intent to revoke and an opportunity for hearing before the City council shall be provided before revocation of any permit for a violation of any condition thereof or of this article or any applicable state or federal statutes, rules or regulations.
[Ord. No. 45-1999, § 700.21, 2-1-2000]
The City may require any user to develop and implement an accidental discharge/slug control plan. At least once every two years, the City shall evaluate whether each significant industrial user needs such a plan. Any user required to develop and implement an accidental discharge/slug control plan shall submit a plan which addresses, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the City of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the prohibited discharge standards in this article; and
(4) 
Procedures to prevent adverse sewage works impacts from any accidental or sludge 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 organic pollutants (including solvents), and/or measures and equipment for emergency response.
[Ord. No. 45-1999, § 700.22, 2-1-2000]
Where additional pretreatment and/or operation or maintenance activities will be required to comply with this article, the user shall provide a declaration of the shortest schedule by which the user will provide such additional pretreatment and/or implementation of additional operation and maintenance activities. The City reserves the right to determine the reasonableness of the proposed schedule, to modify the proposed schedule, or to reject the schedule. The schedule shall contain milestone dates for the commencement and completion of major events leading to the construction and operation of additional treatment required for the user to comply with the requirements of this article, including, but not limited to, dates relating to hiring an engineer, completing preliminary plans, completing final plans, executing contracts for major components, commencing construction, completing construction, and all other acts necessary to achieve compliance with this article. No later than 14 days following each milestone date in the schedule and the final date for compliance, the user shall submit a progress report to the City including, at a minimum, a statement as to whether or not it complied with the increment of progress represented by that milestone date and, if not, the date on which it expects to comply with this increment of progress, the reason for delay, and the steps being taken by the user to return to the approved schedule.
[Ord. No. 45-1999, § 700.23, 2-1-2000]
All significant industrial users shall, at a frequency stated in their wastewater permit or as determined by the City, but in no case less than twice per year, submit a report to the City indicating the nature and concentration of pollutants in the discharge which are limited by pretreatment permit criteria or standards in this article and the measured or estimated average and maximum daily flows and loadings for the reporting period. All periodic compliance reports must be signed and certified in accordance with this article. All wastewater samples collected must be representative of the user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge. If a user subject to the reporting requirements in this article or its permit monitors any pollutant more frequently than required, the results of this additional monitoring shall be included in the report.
[Ord. No. 45-1999, § 700.24, 2-1-2000]
Each user must notify the City in writing of any planned significant changes to its operations or process systems which might alter the nature, quality or volume of its wastewater at least 60 days before the change. No user shall implement the planned changed conditions until and unless the City has responded in writing to the user's notice. Significant changes include, but are not limited to, flow or pollutant load increases of 10% or greater, and the discharge of any previously unreported pollutants.
[Ord. No. 45-1999, § 700.25, 2-1-2000]
If sampling performed by a user indicates a violation of the permit or this article, the user must notify the City within 24 hours of becoming aware of the violation. The user shall also, within five calendar days, repeat the sampling and analysis and submit the results of the repeat analysis to the superintendent within five calendar days of such repeat sampling and analysis. In the case of any discharge, including, but not limited to, hazardous waste discharges, accidental discharges, discharges of a nonroutine or episodic nature, a noncustomary batch discharge, or a slug load, that may cause potential problems for the sewage works, the user shall immediately telephone and notify the City of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user. Within five days following such a discharge, the user shall submit a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the sewage works or natural resources or other damage to person or property, nor shall such notification relieve the user of any fines, penalties or other liability which may be imposed pursuant to this article. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a discharge described in this section. Employers shall ensure that all employees who may cause such a discharge to occur are advised of the emergency notification procedure.
