(7) Any additive intended to be placed into an interceptor or building drain on a constant, regular or scheduled basis shall have City approval prior to its use. Such additives may include, but are not limited to, commercially available bacteria or other additives designed to absorb, consume or treat fats, oils or grease.
(b) Grease, oil and grit interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers.
(1) Interceptors shall meet the requirements contained in the OBC-Plumbing Code.
(2) Interceptors shall have one inlet and one outlet pipe.
(3) Interceptors installed on the exterior of any building shall be provided with a cast iron manhole frame and cast iron cover on each chamber to provide access for inspection, maintenance and cleaning.
(4) Where exposed to vehicular traffic in parking or driving areas, the interceptor shall be designed to have adequate load-bearing strength by a registered Professional Engineer, certified in the State of Ohio.
(5) Site plans for any additions or renovations made to existing interceptor facilities shall be submitted to the City. Site plans shall be signed and sealed by a registered Professional Engineer, certified in the State of Ohio.
(6) FSE's located in new buildings shall have an interceptor installed exterior to the building with a minimum capacity of 1,000 gallons and conform to Appendix A or City Design Specifications as they are amended unless a variance is granted by the Director. The maximum capacity for any interceptor installed on the building exterior shall be 3,000 gallons. For required capacities in excess of 3,000 gallons, multiple units in series shall be required.
(7) New FSE interceptors shall have a minimum of two compartments separated by a baffle with fittings designed for grease contact and retention and be installed and connected so that each compartment is easily accessible for inspection, cleaning and removal of the intercepted grease and/or oil and accumulated sludge and for viewing and sampling of the liquid that is discharged to the public sewer from the interceptor.
(8) New FSE's located in existing buildings shall comply with the requirements applicable to new constructions provided that it is feasible. Where infeasible to install an interceptor on the exterior of the building, under-sink or in-line grease traps for use on individual fixtures, including sinks and other drains that have potential to contain grease, may be allowable subject to the approval of the Director. The FSE bears the responsibility of demonstrating to the City that an interceptor installed on the exterior of any building is infeasible.
(9) Under-sink or in-line grease traps shall meet PDI-G101 standards as a minimum.
(10) Existing FSE interceptors that are under-designed, substandard or defective, as determined by the Director, shall be replaced with a 1 ,000 gallon interceptor that conforms to Appendix A or City Design Specifications as they are amended within a period not to exceed six months of notification by the City, unless otherwise determined by the Director.
(11) Existing FSE under-sink or in-line grease traps that are under-designed, substandard or defective, as determined by the Director, shall be replaced with City-approved grease intercepting equipment within a period not to exceed six months of notification by the City, unless otherwise determined by the Director. New under-sink or in-line grease traps may be allowed. However, when conditions exist and where feasible to install on the exterior of the building, a 1,000 gallon interceptor that conforms to Appendix A or City Design Specifications as they are amended shall be required.
(12) The Director may evaluate interceptor sizing on an individual basis for facilities having unusual patterns of operations, including, but not limited to, highly variable flows to the grease interceptor, high volume of grease discharge or other special conditions.
(c) Inspection of interceptors, under-sink traps or in-line grease traps for conformance with OBC-Plumbing Code and City requirements and other criteria required by this Chapter shall be performed by the Director in accordance with provisions set forth in Section 911.14
.
(1) Inspections may be for installations or operations.
(2) Inspections may be on a scheduled or unscheduled basis as determined by the Director. Nonconforming facilities shall be required to develop a plan to improve the interceptor, under-sink trap or in-line grease trap performance through increased maintenance and/or improved management practices or be required to install interceptor equipment that meets OBC-Plumbing Code and City requirements.
(d) Where installed, all interceptors, under-sink traps or in-line grease traps shall be operated and maintained by the owner, at his expense, and shall be in continuously efficient operation at all times.
(1) Maintenance shall include the complete removal of all contents including floating materials, liquid and solids that have accumulated on the bottom of the interceptor compartments, under-sink traps or in-line grease traps. All adhered grease should be scraped and removed during the process.
(2) Decanting or discharging of removed waste back into the interceptor, under-sink trap or in-line grease trap from which the waste was removed or any other interceptor, under-sink trap or in-line grease trap for the purpose of reducing the volume to be disposed is prohibited. In no way shall the removed waste be returned to any building sewer or any portion of the POTW.
(3) Continuously running hot water through an interceptor, under-sink trap or in-line grease trap for purposes of cleaning the interceptor, under-sink trap or in-line grease trap is prohibited. Dishwashers equipped with booster heaters and/or using water in excess of 140 degrees Fahrenheit shall not pass through any under-sink, in-line grease trap or interceptor with less than a 1,000 gallon capacity.
(4) All FSE interceptors shall be pumped out completely at least once every twelve weeks or as otherwise required by the Director to prevent the release of grease, oil and/or grit to the POTW. Under-sink or in-line grease traps shall be cleaned out completely at least once every four weeks or as otherwise required by the Director to prevent the release of grease, oil, and/or grit to the POTW.
(5) All non-FSE interceptors should be inspected every 12 weeks and pumped out completely as needed to prevent the release of grease, oil and/or grit to the POTW.
(6) Maintenance records shall be kept and maintained on-site by the owner for a period of not less than two years. Such maintenance records must include date, time, and name of person performing the maintenance on an under-sink or in-line grease trap or name and number of company performing interceptor service. Such maintenance records must also include invoices (or copy of original invoices) from any company performing interceptor service. The maintenance records shall be subject to review and inspection by the City when requested. The City has the right to contact any company providing interceptor service to an FSE associated with the City POTW to confirm dates of service.
