938.05 GREASE INTERCEPTOR DESIGN AND MAINTENANCE REQUIREMENTS.
   (a)    General Provisions.
      (1)    The installation of a proper interceptor shall be the responsibility of the user who applies for the connection and the user whose operations cause or contribute to the necessity for an interceptor.
      (2)    Interceptors shall be installed, utilized, and properly maintained for continuous and efficient operation at all times and at the expense of the user.
      (3)    The Administrative Authority shall approve the type, capacity and construction of all interceptors in writing prior to installation.
      (4)    A common interceptor shared by multiple businesses can be utilized if specifically authorized by the Director and upon evidence of legal operating and maintenance agreements between the involved property owners.

   (b)    Design.
      (1)    Interceptors for food service establishments shall be sized and designed in compliance with the Uniform Plumbing Code, unless otherwise specified herein.
      (2)    Other factors that may influence the design include, but shall not be limited to the following:
         A.   The type of facility (such as a restaurant, bakery, food processing factory, etc.).
         B.   The volmne of the user's business or operation (such as number of meals served, number of seats, hours of operation, etc.).
         C.   The peak flow of process wastewater discharged to the collection system.
         D.   Size and nature of facilities (including kitchen facilities) based on size, type, number of fixtures, and type of processing or cooking equipment used.
         E.   The type of service provided or operation undertaken (such as dine-in meal service versus carry-out meal service).
         F.   The type of foods or other materials used in cooking, processing, or manufacturing operations conducted within the facility.
         G.   The overall potential for grease-laden discharges.
         H.   The existence of devices, procedures or processes designed to minimize the amount of fats, oil or grease from entering the collection system.
         I.   The location of the facility, if it is located in a known problem area.
         J.   Any prior problems with the facility, such as blockages, violations, etc.
      (3)    All hydromechanical shall be designed and tested in accordance with ASME A112.14.3, ASME A112.14.4, CSA B481.1, PDI G101 or PDI G102 and sized according to ASME A112.14.3, ASME A112.14.4, ASME A112.14.6, CSA B481.3 or PDI G101. All gravity grease interceptors shall be designed and tested in accordance with IAPMO/ANSI Z1001. Gravity grease interceptors with fats, oils, and greases disposal systems shall be designed and tested in accordance with ASME A112.14.6 and IAPMO/ANSI Z1001.
      (4)    All grease interceptors shall include an effluent sample box of a type and size approved by the Administrative Authority.
      (5)    Inspection by the Administrative Authority, or an Authorized Inspector, of installed interceptors and piping prior to backfilling is required. Piping shall meet the requirements of the Uniform Plumbing Code.
      (6)    Interceptors shall have a sanitary tee located inside the sample box on the discharge side of the sample box.
      (7)    Interceptors shall have a cleanout installed after the sample box on the private lateral and at intervals required by the Uniform Plumbing Code.
      (8)    All manholes and sample boxes to be installed a minimum of one-half inch above the finished grade with a concrete collar a minimum of eighteen inch (18") around the manhole and sample box lids.
   (c)    Interceptor Maintenance.
      (1)    Any user who is required by the Director or this ordinance to install or operate an interceptor shall be required to adequately maintain the interceptor at the user's expense, so that the interceptor is in proper working order at all times. Maintenance shall include the complete removal of all contents, including floating materials, wastewater, sludge, and solids. Decanting or discharging of removed waste back into the interceptor from which the waste was removed or into any other interceptor, for the purpose of reducing the volume to be hauled is prohibited.
      (2)    Grease interceptors at minimum shall be cleaned out completely by a permitted waste hauler quarterly (every three (3) months) to assure that the interceptor will operate as designed at all times or as otherwise specified by the Administrative Authority.
      (3)    The use of additives, directly or indirectly to the plumbing or sewer system, to emulsify grease and/or oil is specifically prohibited.
      (4)    The use of biological additives as a supplement to interceptor maintenance, including the addition of micro-organisms, may be authorized by the Director and approval shall be obtained in writing prior to the use of such additives.
      (5)    A maintenance log indicating each pumping of an interceptor for the previous twelve (12) months and any other pertinent information shall be maintained by each establishment. This log shall include, but not limited to, date, time, amount pumped, hauler, and disposal site, and the log shall be kept in a conspicuous location for inspection by the Administrative Authority or an Authorized Inspector during normal business hours.
      (6)    All users must sign a waste manifest form before having a waste load transported by a permitted hauler. The user shall also keep copies of the manifest form for a period of at least three (3) years and make all manifest records available for inspection by the Administrative Authority during normal business hours.
      (7)    All waste removed from an interceptor must be disposed at a facility permitted by the State of Ohio or applicable regulatory agencies to receive such waste. The pumpage shall not be returned to the public sewer system or manhole, any private wastewater system or storm drains.
      (8)    All interceptors shall be located as to be readily and easily accessible for cleaning, inspection, and removal of intercepted waste.
      (9)    Any fixture connected to a grease interceptor shall have a non-removable, secured food strainer of such integrity to withstand daily operational usage.
   (d)    Required Connections to Interceptor. All three-compartment sinks, scullery (preparation) sinks, floor drains, and mop sinks along a cook line, pre-wash sinks at dishwashing stations, and all other fixtures that contribute grease into the wastewater system shall be connected to an interceptor.
   (e)    Prohibited Connections or Additives to Interceptors.
      (1)    Final rinse discharge from automatic dishwashers shall not be connected to the interceptor.
      (2)    The use of any additive, such as enzymes, surfactants or chemicals shall not be connected to any type of interceptor.

      (1)    Applicants or users shall be required to submit copies of detailed facility proposed interceptors, pretreatment facilities, spill containment facilities, and operating procedures, to the Zoning Department. Facility plans shall also include site plans, floor plans, mechanical and plumbing plans, and details to show all wastewater plumbing, spill containment, and appurtenances by size, location, and elevation. The review of the plans and procedures shall in no way relieve the user of the responsibility of modifying the facilities or discharge, and to meet the requirements of this chapter or any requirements of other regulatory agencies.
      (2)    All submitted drawings shall be prepared by a licensed and registered professional engineer. Any false information or misleading calculations submitted shall be the responsibility of the user.
