(a) The purpose of the City of Zanesville, Ohio’s Fat, Oil and Grease program is to education and monitor Food Service Establishments on proper fat, oil and grease management. This includes best management practices and other approved strategies to aid in the prevention of fats, oils and greases accumulating in the municipal wastewater system that may cause sanitary sewer blockages and obstructions.
(b) Definitions.
(1) “Fats, Oils and Greases” or “FOG” means organic polar compounds derived from animal and/or plant sources that contain multiple carbon chain triglyceride molecules. These substances are detectable and measurable using analytical test procedures established in 40CFR 126, as may be amended from time to time. All are sometimes referred to herein as “grease” or “greases” or “FOG”.
(2) “Food Service Establishments” or “FSE” means an establishment which has as one of its primary purposes the activity of preparing, manufacturing, processing and serving or otherwise making available for consumption, foodstuffs, such as restaurants, caterers, commercial kitchens at facilities such as schools, hospitals, nursing homes, prisons, correction facility, or other similar institutes, or any other facility that discharges FOG at a level above the effluent limits set forth in Section 923.11(c) of the Codified Ordinances of the City of Zanesville. An FSE does not include a personal residence or a home based daycare which serves meals to less than 5 unrelated individuals each day.
(3) “Grease interceptor” means a device for separating waterborne greases and grease complexes from wastewater and retaining such greases and grease complexes prior to the wastewater exiting the interceptor and entering the sanitary sewer collection and treatment system. Grease interceptors also serve to collect solids that settle, generated by and from activities that subject FSE’s to this section, prior to the water exiting the interceptor and entering the sanitary sewer collection and treatment system. Grease traps and interceptors are sometimes referred to herein as “grease interceptors”.
(c) Grease Interceptor Installation for New Establishments. All Food Service Establishments that begin doing business after the effective date of this section shall install an appropriate grease interceptor as determined by a qualified professional engineer and as approved by the Zanesville Muskingum County Health Department Plumbing Inspector and the Zanesville Public Service Director during the plan review process prior to installation.
(d) Existing Establishments. All Food Service Establishments in business prior to the effective date of this section, which have grease interceptors already installed, whether inside or outside of the establishment, must meet the provisions set forth in Section 923.11(c) of the Codified Ordinances of the City of Zanesville, and if it is determined that they are failing to do so or if they renovate the plumbing in their establishment they must then install an appropriate grease interceptor as determined by a qualified professional engineer and as approved by the Zanesville Muskingum County Health Department Plumbing Inspector and the Zanesville Public Service Director during the plan review process prior to installation.
(e) Grease Interceptor Inspections and Maintenance Monitoring. Grease interceptor monitoring shall be completed during Food Service Establishment Inspections performed by the Zanesville Muskingum County Health Department Plumbing Inspector and Zanesville Public Service Director. Section 923.08 of the City of Zanesville’s Sewer Use Regulations provides for special interceptors and their maintenance. The use of enzymes and other biological agents is prohibited unless approved by the City of Zanesville’s Director of Public Service.
(f) Maintenance. Food Service Establishments shall perform adequate maintenance on grease interceptors to maintain optimal performance as determined by the Zanesville Muskingum County Health Department Plumbing Inspector and Zanesville Public Service Director. FSE’s shall keep up-to-date maintenance records including hauling manifests, inspection logs and repair logs. These records shall be retained for a minimum of 3 years and shall be made available to Zanesville Muskingum County Health Department sanitarians and Zanesville Public Service Director upon request.
(h) Exemptions. The Zanesville Public Service Director shall have the authority to grant exemptions to the requirements set forth in this section if the Director believes that a strict compliance would place an undue burden upon the FSE and the Director believes that the integrity of the City’s sewer system will not be adversely affected by the exemption.
