(A) Fat, oil and grease (FOG), waste food and sand interceptors. FOG, waste food and sand interceptors shall be installed when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing fats, oils and grease, any flammable wastes, ground food waste, sand, soil and solids, or other harmful ingredients in excessive amount which impact the wastewater collection system. Such interceptors shall not be required for single family residences, but may be required on multiple family residences. All interceptors shall be of a type and capacity approved by the Superintendent, and shall be located as to be readily and easily accessible for cleaning and inspection.
(B) Fat, oil, grease and food waste.
(1) New construction and renovation. Upon construction or renovation, all restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, prisons, jails, churches, camps, caterers, manufacturing plants and any other sewer users who discharge applicable waste shall submit a FOG and food waste control plan that will effectively control the discharge of FOG and food waste.
(2) Existing structures. All existing restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, prisons, jails, churches, camps, caterers, manufacturing plants and any other sewer users who discharge applicable waste shall be required to submit a plan for control of FOG and food waste, if and when the Superintendent determines that FOG and food waste are causing excessive loading, plugging, damage or potential problems to structures or equipment in the public sewer system.
(3) Implementation of plan. After approval of the FOG plan by the Superintendent the sewer user must:
(a) Implement the plan within a reasonable amount of time;
(b) Service and maintain the equipment in order to prevent impact upon the sewer collection system and treatment facility. If in the opinion of the Superintendent the user continues to impact the collection system and treatment plan, additional pretreatment may be required, including a requirement to meet numeric limits and have surcharges applied;
(c) Sand, soil and oil interceptors: all car washes, truck washes, garages, service stations and other sources of sand, soil and oil shall install effective sand, soil and oil interceptors. These interceptors shall be sized to effectively remove sand, soil and oil at the expected flow rates. The interceptors shall be cleaned on a regular basis to prevent impact upon the wastewater collection and treatment system. Owners whose interceptors are deemed to be ineffective by the Superintendent may be asked to change the cleaning frequency or to increase the size of the interceptors. Owners or operators of washing facilities will prevent the inflow of rainwater into the sanitary sewers;
(d) Laundries: commercial laundries shall be equipped with an interceptor with a wire basket or similar device, removable for cleaning, that prevents passage into the sewer system of solids one-half inch or larger in size such as strings, rags, buttons or other solids detrimental to the system;
(e) Control equipment: the equipment of facilities installed to control FOG, food waste, sand and soil, must be designed in accordance with the State Department of Environment and Conservation engineering standards or applicable city guidelines. Underground equipment shall be tightly sealed to prevent inflow of rainwater and easily accessible to allow regular maintenance. Control equipment shall be maintained by the owner or operator of the facility so as to prevent a stoppage of the public sewer, and the accumulation of FOG in the lines, pump stations and treatment plant. If the city is required to clean out the public sewer lines as a result of a stoppage resulting from poorly maintained control equipment, the property owner shall be required to refund the labor, equipment, materials and overhead costs to the city. Nothing in this division (B)(3)(e) shall be construed to prohibit or restrict any other remedy the city has under this chapter, or state or federal law. The city retains the right to inspect and approve installation of control equipment;
(f) Solvents prohibited: the use of degreasing or line cleaning products containing petroleum based solvents is prohibited. The use of other products for the purpose of keeping FOG dissolved or suspended until it has traveled into the collection system of the city is prohibited; and
