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 13.05.031 of this article within the time limitations specified by EPA, the state, or the city manager, 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 city manager for review, and shall be acceptable to the city manager 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.
(Ordinance 4845 adopted 1/19/2021)
(a) 
Whenever deemed necessary, the city manager 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 waste streams from industrial waste streams, and such other conditions as may be necessary to protect the POTW and determine the users compliance with the requirements of this article.
(b) 
The city manager 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 city manager, 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 type and capacity approved by the city manager 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.
(Ordinance 4845 adopted 1/19/2021)
Within one year of becoming a significant industrial user, the city manager shall evaluate whether each significant industrial user needs an accidental discharge/slug discharge control plan. The city manager may require any user to develop, submit for approval, and implement such a plan. Alternatively, the city manager may develop such a plan for any user. An accidental discharge/slug discharge 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 city manager of any accidental or slug discharge, as required by section 13.05.156; 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.
(Ordinance 4845 adopted 1/19/2021)
(a) 
Septic tank waste may be introduced into the POTW only at locations designated by the city manager, and at such times as are established by the city manager. Such waste shall not violate sections 13.05.031 through 13.05.034 or any other requirements established by the city. The city manager may require septic tank water haulers to obtain wastewater discharge permits.
(b) 
The city manager shall require haulers of industrial waste to obtain wastewater discharge permits. The city manager may require generators of hauled industrial waste to obtain wastewater discharge permits. The city manager also may prohibit the disposal of hauled industrial waste. The discharge of hauled industrial waste is subject to all other requirements of this article.
(c) 
Industrial waste haulers may discharge loads only at locations designated by the city manager. No load may be discharged without prior consent of the city manager. The city manager may collect samples of each hauled load to ensure compliance with applicable standards. The city manager may require the industrial waste hauler to provide a waste analysis of any load prior to discharge.
(d) 
Industrial waste haulers must provide a waste-tracking form for every load. This form shall include, at a minimum, the name and address of the industrial 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 industry, known or suspected waste constituents, and whether any wastes are RCRA hazardous wastes.
