(a) On or after the effective date of this code or upon notice of the Superintendent, specifically as set forth in 1044.02, an existing facility may be required to install an adequately sized, and properly operated and maintained grease interceptor according to the standards and specifications set forth in this chapter. Any construction shall require all necessary permits as required by this code and approval of the City. A grease interceptor shall be required when any of the following conditions exist:
(1) It is found by the City to be contributing grease in potential quantities sufficient to inhibit sanitary sewer flow or necessitate increased maintenance on the sanitary sewer collection system in order to keep impairments to the main line flow from occurring.
(2) It is remodeling the food preparation or kitchen waste plumbing facilities in such a manner to be subject to a permit issued by the City building department.
(3) Its interceptor allows a discharge of oil or grease in excess of 50 mg/l.
(4) It is required by this or other applicable ordinance to maintain a grease interceptor and is found to be equipped with an undersized grease interceptor. Such a facility shall, within three months of the effective date of this Code, install an adequately sized grease interceptor in accordance with the specifications of this Ordinance. When it can be demonstrated that circumstances exist which would create an unreasonable burden on the person/entity to comply with the time schedule imposed herein, a request for extension of time may be presented for consideration of the Superintendent. All requests for extension of time shall be submitted in writing stating the reasons for such a request. Extensions of time may be granted by the Superintendent for good cause shown. Under no circumstances shall the extension of time exceed twelve months including original time plus extensions after approval of the extension by the Superintendent.
(5) It is required by this code to maintain a grease interceptor and it is found not to be equipped with a grease interceptor. Such a facility shall, within twelve months of the effective date of notice from the Superintendent, install an adequately sized grease interceptor in accordance with the specifications of this code.
(b) New facilities required by this or other applicable ordinances to maintain a grease interceptor shall install such a unit prior to commencement of discharge to the sanitary sewer system.
(c) Any requests for extensions to installation dates must be made in writing to the City, at least thirty days in advance of the compliance date. The written request shall include the reasons for the facility's failure or inability to comply with the compliance date set forth, the additional time needed to complete the remaining work, and the steps to be taken to avoid future delays. The City shall determine the date for compliance if and when it is determined by the Wastewater Department that the cause for delay was justified.
(d) Existing facilities required by this or other applicable ordinances to maintain a grease interceptor that demonstrate that the installation of a grease trap is not feasible may use bioremediation as an alternative. The City will determine whether a facility may exercise this option for sanitary sewer maintenance. The bioremediation method and product must be approved by the City in writing prior to use in the drainage system. In addition, the operator must maintain written documentation of a current contract with a bioremediation supplier approved through the City.
