§ 52.043  ADDITIONAL PRETREATMENT MEASURES.
   (A)   Whenever deemed necessary, the city 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 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 city may require any person discharging into the POTW to install and maintain, on his or her property and at his or her expense, a suitable storage and flow-control facility to ensure equalization of flow. An individual discharge permit may be issued solely for flow equalization.
   (C)   Grease, oil and/or sand interceptors (i.e., traps) provided by the user, shall be installed by all restaurants discharging to the POTW; provided, however, that this requirement may be waived by the city on a case-by-case basis with respect to a restaurant which is not discharging wastewater with oil and grease in greater that normal domestic sanitary sewage levels. In addition, grease traps shall be provided and installed by other users when, in the opinion of the city, they are necessary for the proper handling of any wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for domestic users. All interception units shall be of a type and capacity approved by the city 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 his or her expense. Records of grease trap inspections and maintenance and receipts from the discharge or disposal of all grease shall be maintained onsite at each facility required to have a grease trap.
   (D)   Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
