After reviewing the plan the Director may require that an interceptor be installed. The user will then have one-year from date of notification for the need of an interceptor to become compliant with all of the provisions within this chapter. All new interceptors or interceptors to replace or upgrade existing interceptors will be required to meet all criteria stated in this chapter.
(C) The following must be submitted to the city for review and approval prior to installation of an interceptor.
(1) Site plans showing the location of the interceptor, lines, clean out or manhole and sample port; and
(2) Details of the interceptor, lines, clean out or manhole and sample port; and
(3) Formula and calculation used to determine the interceptor capacity.
(D) No non-grease-laden sources are allowed to be connected to sewer lines intended for grease, oil and sand separators.
(E) After approval of the FOG plan by the Director the user must implement the plan in order to prevent adverse impact upon the sewer collection system and treatment facility within one year. If in the opinion of the Director the user continues to impact the collection system and treatment plant, additional pretreatment measures may be required.
(F) The equipment or facilities installed to control FOG, food waste, sand and soil, must be designed in accordance with the Uniform Plumbing Code. Control equipment shall be maintained by the owner so as to prevent a stoppage of the public sewer, and the accumulation of FOG in the lines, pump stations and treatment plant.
(G) The city, or its designee, retains the right to inspect and approve installation of the control equipment.
(H) All interceptors shall be sized to ensure that the city's sewer system is protected from excessive FOG and debris which may cause clogging or damage and that the user is capable of meeting all discharge requirements.
(I) All interceptors shall be located outside the building in such a manner that personnel from the city Division of Wastewater can inspect the interceptors at any time.

(K) Access manholes, with a minimum diameter of 24 inches, shall be provided over each chamber and sanitary tee. The access manholes shall extend at least to finished grade and be designed and maintained to prevent water inflow or infiltration. The manholes shall also have readily removable covers to facilitate inspection, grease removal, and wastewater sampling activities.
(L) If an establishment desires, because of documented space constraints, an alternate to an out-of-building grease interceptor, the request for an alternative location shall contain the following information:
(1) Location of city sewer main and easement in relation to available exterior space outside building; and
(2) Existing plumbing at or in a site that uses common plumbing for all services at that site.
