Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section 13.08.031 of this article within the time limitations specified by the EPA, the state, the control authority, or the DCO, 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 DCO for review, and shall be acceptable to 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 article.
(2005 Code, sec. 13.4.120)
(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 article.
(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.
(c) 
Grease, oil, and sand interceptors shall be provided when, in the opinion of the DCO, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the DCO and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense.
(d) 
Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter, or other control device, as deemed necessary by the DCO.
(2005 Code, sec. 13.4.121)
At least once every two (2) years, the DCO shall evaluate whether each permitted significant industrial user needs an accidental discharge/slug control plan. The DCO may require any user to develop, submit for approval, and implement such a plan. An accidental discharge/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 control authority of any accidental or slug discharge, as required by section 13.08.186 of this article; 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.
(2005 Code, sec. 13.4.122)
(a) 
Septage 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. Such waste shall not violate division 2 of this article or any other requirements established by the city. The DCO and/or control authority may require septic tank waste haulers to obtain wastewater discharge permits.
(b) 
Septage 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.
