(A) 
Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section 171.04 of this chapter within the time limitations specified by EPA, the state, or the DCO, whichever is more stringent.
(B) 
Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense.
(C) 
Detailed plans describing such facilities and operating procedures shall be submitted to the DCO for review, and shall be acceptable to, and approved by the DCO 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 the provisions of this chapter.
(D) 
Any user responsible for wastewater discharges through a building sewer, may be required, at the user's expense, to:
(1) 
Install an approved control manhole in a location approved for accessibility and safety, and which allows for representative sampling of regulated waste streams;
(2) 
Install approved pretreatment equipment and other devices to facilitate observation, sampling and measurement of the discharge; and
(3) 
Maintain the equipment and facilities as needed, or as required by the DCO.
(Ordinance 4229 adopted 9/24/2024)
(A) 
Whenever deemed necessary, the DCO 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 require such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
(B) 
The DCO may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(Ordinance 4229 adopted 9/24/2024)
(A) 
Grease, oil, and sand interceptors and sample access shall be provided at the user's expense, when, in the opinion of the DCO, they are necessary for the proper management of wastewater which may contain amounts of grease and oil, sand and grit, or other pollutants prohibited by this chapter; except that these interceptors shall not be required for residential users. All interceptor units shall:
(1) 
Be of a type, capacity and location approved by the DCO;
(2) 
Be easily accessible for cleaning and inspection;
(3) 
Be inspected, cleaned, and repaired regularly, as needed, by the user at the user's expense;
(4) 
Be installed with approved sample access, when required; and
(5) 
Be upgraded in capacity or to provide for sample access, when required.
(B) 
Interceptors shall be cleaned and maintained so that pollutants do not overload the skimming and settling capacity of the interceptor, or discharge grease, oil, grit or other pollutants in a manner or amount that restricts or clogs any sewer line.
(Ordinance 4229 adopted 9/24/2024)
(A) 
The DCO shall evaluate whether each permitted SIU needs a slug control plan, or other action to control slug discharges no later than one year of the SIU determination.
(B) 
The DCO may require any user to develop, submit for approval, and implement such a plan. All the activities associated with slug control evaluation and results are to be kept in the industrial user file.
(C) 
A slug control 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 DCO and TRA of any slug discharge, as required by section 171.34 of this chapter; and
(4) 
Procedures to prevent adverse impact from any 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.
(Ordinance 4229 adopted 9/24/2024)
(A) 
Septic tank waste may be introduced into the POTW only at locations designated by the DCO and Control Authority, and at such times as are established by the DCO and Control Authority.
(B) 
Such waste shall not violate section 171.04 through 171.07 of this chapter or any other requirements established by the city, such as chapter 172 on liquid waste. The DCO and/or Control Authority may require septic tank waste haulers to obtain wastewater discharge permits.
(C) 
Septic tank waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the waste hauler, permit number, truck identification, names and addresses of sources of waste, and volume and characteristics of waste. The form shall identify the type of generator, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
(Ordinance 4229 adopted 9/24/2024)
The DCO may develop best management practices (BMPs), and require users to implement such BMPs, if necessary, to protect the POTW. Such BMPs would be supplemental and not used as a replacement for compliance with local limits listed in section 171.07 and prohibited discharge standards in section 171.04.
