Users shall provide necessary wastewater treatment to comply with this article and shall achieve compliance with all applicable categorical pretreatment standards, local limits, and the prohibitions established by this article in subdivision II of this division within the time limitations specified by the environmental protection agency, the state, or the control authority, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user’s expense. Detailed plans describing such facilities and operating procedures shall be submitted to the control authority for review and shall be acceptable to the control authority before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the city under this article.
(1966 Code, sec. 32-125(a); 2001 Code, sec. 106-851; Ordinance 20-2020, sec. 1, adopted 4/7/20; Ordinance 12-2021 adopted 4/20/21)
(a) 
Whenever deemed necessary, the control authority may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and meet such other conditions as may be necessary to protect the publicly owned treatment works and determine the user’s compliance with the requirements of this article.
(b) 
The control authority may require any person discharging into the publicly owned treatment works to install and maintain, on his property and at his expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization. All records, charts, recorded charts or strips, and logs of such controls shall be maintained and provided upon request of the control authority.
(c) 
Grease, oil, and sand interceptors or traps shall be provided when, in the opinion of the control authority, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; however, such interceptors or traps shall not be required for residential users. All interception units shall be of a type and capacity approved by the control authority and shall be so located to be easily accessible for cleaning and inspection. Such interceptors or traps shall be inspected, cleaned, and repaired regularly, as needed, by the user at his expense. A record of maintenance, repairs, and a log of pumping and waste hauling of contents shall be maintained and provided to the control authority upon request.
(d) 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(e) 
The control authority may require any user to install or have installed at the user’s expense a control manhole, of a size and construction approvable by the control authority. Additionally, the control authority may require the user to construct or have constructed at the user’s expense any structures, appurtenances, fences, embankments, rail guards, posts, security system, or any other device with eye bolts, locks, lights, signs, or any other device to ensure the security and safety of control authority personnel and sampling equipment.
(1966 Code, sec. 32-125(b); 2001 Code, sec. 106-852; Ordinance 25-2002, sec. 1, adopted 4/2/02; Ordinance 20-2020, sec. 1, adopted 4/7/20; Ordinance 12-2021 adopted 4/20/21)
(a) 
Within one year of being designated as a SIU and at least once every two years thereafter whether each SIU needs a plan or other action to control slug discharges. The control authority may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary. Alternatively, the control authority may develop such a plan for any user. An accidental discharge plan shall address, 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 control authority, other regulatory agencies such as the EPA and the approval authority, and the appropriate wastewater treatment plant of any accidental or slug discharge, as required by section 106-886; 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 organic pollutants including solvents, and/or measures and equipment for emergency response. The location of floor drains, if present, and any other possible sources of introduction into the waste stream or sanitary sewage system will also be identified.
(b) 
The control authority is required to keep records of the activities associated with slug control evaluations and the results are required to be available to the approval authority upon request.
(1966 Code, sec. 32-125(c); 2001 Code, sec. 106-853; Ordinance 25-2002, sec. 1, adopted 4/2/02; Ordinance 20-2020, sec. 1, adopted 4/7/20; Ordinance 12-2021 adopted 4/20/21)
The following requirements are in addition to section 106-311 and subdivision III of division 2 of this article:
(1) 
Septic tank waste shall only be introduced into the publicly owned treatment works at locations designated by the publicly owned treatment works and at such times as are established by the publicly owned treatment works. Such waste shall not violate subdivision II of this division or any other requirements established by the city. The control authority shall require septic tank waste haulers to obtain wastewater discharge permits.
(2) 
The control authority may require haulers of industrial wastewater to obtain wastewater discharge permits. The control authority may require generators of hauled industrial wastewater to obtain wastewater discharge permits. The control authority may also prohibit the disposal of hauled industrial wastewater. The discharge of hauled industrial wastewater is subject to all other requirements of this article.
(3) 
Industrial wastewater haulers shall discharge loads only at locations designated by the publicly owned treatment works. No load may be discharged without prior consent of the publicly owned treatment works. The publicly owned treatment works or the control authority may collect samples of each hauled load to ensure compliance with applicable standards. The publicly owned treatment works or the control authority may require the industrial wastewater hauler to provide a waste analysis of any load prior to discharge.
(4) 
Industrial wastewater hauler must provide a trip ticket for every load.
(5) 
The superintendent of the POTW, or his designated representative, may at any time and without prior notice, refuse to allow the discharge of any specific load of hauled wastewater from any particular liquid waste hauler. This refusal may be based upon such criteria as questionable physical characteristics of the hauled wastewater (odor, color, etc.), past history of the manifested liquid waste generator, or any other such information or judgment that the discharge may adversely affect the POTW in any way. In the event of such refusal of discharge, the wastehauler shall provide to the control authority within 30 days, a manifest indicating the proper disposal of that load of hauled wastewater.
(1966 Code, sec. 32-125(d); 2001 Code, sec. 106-854; Ordinance 25-2002, sec. 1, adopted 4/2/02; Ordinance 20-2020, sec. 1, adopted 4/7/20; Ordinance 12-2021 adopted 4/20/21)
(a) 
After treatment to specified standards, the contaminated water will be placed in a sanitary sewer line where possible. Disposal into the sanitary sewer system will be based on the quality of the water, the peak flow to be placed into the sewer, sewer capacity available, and the availability of sanitary sewer systems.
(b) 
If necessary, the treated water can be placed into the storm drainage system. This disposal method will require an approval authority permit to discharge the treated water into the surface waters of the state. Disposal via the storm drain system must not create a nuisance to the properties between the affected site and the public stream where discharge is permitted by the approval authority.
(c) 
Where it is not possible or feasible to dispose of the treated waters in the sanitary sewer or the disposal by storm drain will create a nuisance effect, and no other disposal methods are available, the city will determine the improvements required in the sanitary or storm drain systems to accept the flow. All improvements will be at the sole expense of the owner of the contaminated site. All improvements must be installed per city standards and procedures, and must be dedicated to the city.
(d) 
All waters from a contaminated site, before disposal into a sanitary sewer, must meet the quality standards of this subdivision with the addition of the following standards for BTEX, lead, and total hydro-carbons:
Chemical
ug/liter
mg/liter
Benzene
1,000
1.0
Toluene

0.58
(e) 
Prior to disposal of the treated water from the contaminated site, the site owner must present to the control authority a copy of the approval authority approved plan for corrective action and, as required, an approval authority permit to discharge to surface waters. The control authority will be provided a copy of all laboratory tests conducted to meet the approval authority requirements in the plan for corrective action. The control authority may require additional tests beyond those of the approval authority approved plan of corrective action.
(f) 
These procedures apply to either pump-and-treat flows or batch releases of treated waters from contaminated sites. Under no circumstances will a site owner dispose of treated waters from a LPST contaminated site in the city until authorized to do so by the control authority.
(g) 
The owner will be required to obtain a permit from the control authority. This permit must be renewed annually. The owner must pay an initial permit fee and an annual fee to renew the permit. In addition, each month the owner may pay a fee to defray the cost of reviewing lab results and the results of city-initiated sampling and testing to ensure compliance with both the remedial action plan and the industrial pretreatment ordinance. These costs must be paid until the site is closed by the approval authority and disposal of treated waters has ceased. A statement of the amount of these fees can be obtained from the control authority.
(h) 
If the treated water is disposed of in the sanitary sewer, there will be a minimum monthly charge plus the current commodity charge per 1,000 gallons disposed. The amount disposed generally shall be determined by the rated capacity of the pumps in a pump-and-treat system or by the size of the container in a batch disposal system (added).
