(a) On and after the effective date of this chapter, every existing facility (excepting those facilities to which these regulations do not apply as expressly set forth in Section 913.03 above) shall be required to install an approved, adequately sized, and properly operated and maintained grease interceptor when any of the following conditions exist:
(1) It is found by the City to be contributing grease in quantities that 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 100 mg/l.
(4) It is required by this chapter 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 ninety days of the effective date of this chapter, install an adequately sized grease interceptor in accordance with the specifications of this chapter.
(5) It is required by this chapter or other applicable ordinances to maintain a grease interceptor and is found not to be equipped with a grease interceptor. Such a facility shall, within sixty days of the effective date of this chapter, install an adequately sized grease interceptor in accordance with the specifications of this chapter.
(b) New facilities required by this chapter 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.
(d) Existing facilities required by this chapter 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 use such alternative 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.
