   (A)   Interceptors/traps required.
 
      (1)   Grease interceptors/traps shall be provided and maintained in proper operating condition at all times at the expense of the property owner for the proper handing of liquid waste containing grease. Grease interceptors/traps shall be required for all food service establishments and may be required for other users as determined necessary by the POTW superintendent. Grease interceptors shall be sized, constructed, and installed as required by the city’s specifications and subject to the POTW superintendent’s approval. At a minimum, grease interceptors, traps shall be cleaned and maintained per the manufacturer’s specifications and as provided by this section at the property owner’s expense.
      (2)   Oil and sand interceptors/traps may be required in any establishment where sand, oil, and flammable wastes or other harmful ingredients could enter the wastewater. If a plug or backup occurs and is directly caused by sand and/or oil, the POTW superintendent may require the establishment to install an oil and sand interceptor/trap. Oil and sand interceptors/traps are required for establishments engaged in the washing of motor vehicles.
      (3)   All interceptors/traps shall be of a type and capacity approved by the city, and shall be located as to be readily and easily accessible for cleaning and inspection. Grease, oil and sand interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted into place, shall be gas tight and watertight. Grease interceptors shall provide a minimum capacity of 750 gallons.
      (4)   Where installed, all grease, oil and sand interceptors/traps shall be cleaned and maintained by the owner, at the owner’s sole expense, and shall be kept in continuously efficient operation at all times. At a minimum, any user required to install an interceptor shall comply with the best management practices as provided.
   (B)   Best management practices (BMPs).
      (1)   Any user required to install and maintain an interceptor (trap) of any kind shall develop and carry out a system of maintenance and clean out of such device(s) and shall document and keep:
         (a)   A maintenance schedule;
         (b)   The identity of the person(s) who cleaned and maintained the interceptor; and

§ 68-174 PRELIMINARY TREATMENT.
   (A)   The admission into the public sewers of any waters or wastes:
      (1)   Containing a 5 day BOD greater than 300 mg/l or containing more than 350 mg/l of suspended solids or 10 mg/l of phosphorus;
      (2)   Containing any quantity of substances having the characteristics described in § 68-172; or
      (3)   Having any average daily flow greater than 2% of the average daily flow of the city shall be subject to review and approval of the city. Preliminary treatment shall be provided, at no expense to the city, as may be necessary to reduce the BOD to 300 mg/l and suspended solids to 350 mg/l or to reduce objectionable characteristics of the effluent to within the maximum limits provided for in § 68-172 or to control the quantity and rates of discharges of such waters or wastes. On direction of the city, a person may be required to remove, exclude, or require pretreatment of any industrial waste, in whole or in part, for any reasons deemed to be in the city’s interest. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained in satisfactory and effective operation at no expense to the city. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for approval to the city, and no construction of such facility shall be commenced until the approvals are obtained in writing. The city may elect to treat industrial wastes discharged in excess of normal domestic concentrations on a basis prescribed by written agreement and for an established surcharge to cover the added cost. All such preliminary treatment or pretreatment shall be in accordance with federal and state laws and regulations, including §§ 68-186 et seq. All expenses of city services of such preliminary treatment facilities, plans and specifications shall be borne by the owner.
   (B)   Grinder pump station required.
      (1)   Grinder pump station shall be provided and maintained in the proper operating condition at all times at the expense of the property owner for the proper handling of liquid waste containing any materials which would be capable of causing an obstruction to flow in sewers or other interference with the proper operation of the sewage works.
      (2)   Grinder pumps will be required for any non-domestic user whom may have the potential of discharging any material which may cause obstruction to sewer flow. Grinder pumps may be required for other users as determined necessary by the POTW superintendent.
      (3)   Grinder pump stations shall be of a type and capacity approved by the city and shall be located as to be readily and easily accessible for cleaning, inspection, and maintenance.
      (4)   Each property owner served by a grinder pump shall close the sewage system and cease operation during any period when the grinder pump and/or low pressure system serving a property is inoperable.
      (5)   Each property owner served by a grinder pump shall bear full responsibility for providing, installing, using, operating, maintaining, servicing, repairing, and replacing his or her grinder pump and/or its low pressure force main or lateral, unless otherwise set forth herein.

§ 68-175 INDUSTRIAL WASTES.
   (A)   The owner of any property served by a building sewer carrying industrial waste shall install a suitable control manhole 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.
   (B)   All measurements, test and analyses of the characteristics of waters and wastes to which references are made in §§ 68-172 and 68-174 shall be determined in accordance with Guidelines Establishing Test Procedures for Analysis of Pollutants, Federal Regulation, 40 C.F.R. 136, as amended, published in the Federal Register, and shall be determined at the control manhole provided for in subsection (A) of this section or upon suitable samples taken at the control manhole. If no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
   (C)   No statement contained in this section shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city, subject to payment of surcharge by the industrial concern.
(1993 Code, § 68-175) (Ord. passed 1-22-2001; Ord. 2014-01, passed 1-27-2014)
§ 68-176 GENERAL/SPECIFIC PROHIBITIONS.
   (A)   Allowable bypasses. An industrial user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to ensure efficient operation. These bypasses are not subject to the provision of subsections (C) and (D) of this section.
   (B)   Notice.
      (1)   If an industrial user knows in advance of the need for a bypass, it shall submit prior notice to the POTW, at least 10 days before the date of the bypass if possible.
      (2)   An industrial user shall submit oral notice of an unanticipated bypass that exceeds applicable pretreatment standards to the POTW within 24 hours from the time it becomes aware of the bypass. A written submission shall also be provided within 5 days of the time the industrial user 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 POTW may waive the written report on a case-by-case basis if the oral report has been received within 24 hours.
   (C)   Conditions.
      (1)   Bypass is prohibited, and the POTW may take enforcement action against an industrial user for a bypass, unless:
         (a)   Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
         (b)   There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
         (c)   The industrial user submitted notices as required under subsection (C) of this section.
      (2)   The POTW may approve an anticipated bypass, after considering its adverse effects, if the POTW determines that it will meet the 3 conditions listed in subsection (C)(1) of this section.

§§ 68-177 – 68-185 RESERVED.
DIVISION 5. PRETREATMENT
§ 68-186 PURPOSE AND POLICY.
   (A)   This division sets forth requirements for dischargers into the POTW wastewater collection systems, treatment systems, surface waters, groundwaters, storm sewers, septic systems, dry wells or on the ground and enables the city POTW to protect public health, the environment and the POTW in conformity with all applicable local, state and federal laws relating thereto.
   (B)   The objectives of this division are to:
      (1)   Control or prevent the introduction of pollutants into the municipal wastewater system which will interfere with the normal operation of the system or contaminate the resulting municipal sludge;
      (2)   Control or prevent the introduction of pollutants into the municipal wastewater system which do not receive adequate treatment in the POTW and which will pass through the system into receiving waters or the atmosphere or otherwise be incompatible with the system;
      (3)   Improve the opportunity to recycle and reclaim wastewater and sludge from the system;
      (4)   Control or prevent discharges or potential discharges (storage of materials) to systems or areas under the jurisdiction of this city that may impair the environment.
   (C)   The city will be responsible for the monitoring of the pretreatment program, unless the industrial user has written permission from the city to perform its own monitoring. If the city performs the monitoring, it has the right to demand reimbursement of all labor, maintenance and lab fees associated with the monitoring period. If the industrial user has written permission to perform its own monitoring, the industrial user must notify the POTW within 24 hours of a violation. It is also required that the industrial user resample and resubmit the results within 30 days to the POTW.
