A.
Purpose. Fats, oil and grease (FOG) from food service facilities have a significant impact on the operations of the sewer lines, pump stations, wastewater treatment facilities and other associated appurtenances. It is necessary to provide control for oil and grease to protect the property of the City. Oil/water separators that treat petroleum-based oils and greases are exempt from this section of the requirements.
B.
For all new and existing food service facilities, grease, oil and/or sand interceptors and traps shall be provided for the proper handling of FOG liquid wastes, or any flammable wastes, sand and other harmful ingredients, except that such interceptors shall not be required for private living units. All interceptors shall be of a type and capacity approved by the Delaware Department of Health and Social Services, and shall be located so as to be readily and easily accessible for cleaning and inspection.
C.
Yellow grease shall be recycled to the maximum extent practicable using a permitted rendering company.
D.
FOG interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight. They shall be designed as outlined in § 330-14.
E.
A permit from Kent County shall be required for all grease, oil, and sand interceptors. The owner of a grease, oil or sand interceptor shall maintain the interceptor, at his/her/its own expense, in efficient operating condition at all times. Such interceptors shall be readily accessible and open to inspection by the City at any time.
F.
Commercial or institutional facilities that utilize subfloor or exterior-located FOG interceptors and/or traps as an oil or grease removal device prior to wastewater discharge to the City's sanitary sewer shall have each trap serviced at least once every quarter, or more frequently as specified in the Kent County permit or required to maintain the operability of the unit, to remove and dispose of oil or grease. All the interceptors shall be serviced by a grease hauler licensed by the State of Delaware to transport such waste, and traps may be serviced by either a licensed hauler or properly trained FSF employees. A grease trap/interceptor maintenance log, as required by Kent County, shall be kept. The log shall contain, at a minimum, the date, time cleaned, name of authorized grease hauler, and quantity of grease removed. This log shall be prominently displayed at the facility and made available for inspection upon request. All service receipts and maintenance records shall be kept on file by the food service facility for a minimum of two years and made available for inspection if requested by the City. The service receipt shall, at a minimum, contain the name and address of the facility serviced, the volume of the waste removed, the date/time of service and the name of the waste hauler providing service. Facilities failing to maintain service receipts, the maintenance log, or failing to have oil or grease traps serviced as provided in this section shall be subject to penalties as provided in § 330-13 of the Code. Facilities which knowingly provide false information with regard to providing service receipts are subject to the provisions of § 330-13.
G.
The use of any chemical, enzyme, emulsifier, live bacteria or other grease cutters or additives designed to liquefy, eliminate, or in any way reduce the presence of grease shall not be permitted without the written approval of the Kent County Environmental Program Manager.
H.
The use of grease decanting, where the material is collected in a tank truck and allowed to decant before returning the liquid back to the grease trap, is not permitted. Removal of grease from the interceptor or trap must be complete and include all liquid and solids from the interceptor and/or trap.
I.
Inspection. The City has the right to inspect all food service facilities on a scheduled or unscheduled basis. A quarterly inspection shall be conducted for all permitted facilities to ensure compliance based on operation and maintenance of fats, oils, and grease interceptors and traps according to the Kent County permit and City of Harrington Code requirements, including review of past inspection and/or service logs that are required. The City shall have the right to conduct inspections on a more frequent basis if it is determined by the City Manager, or his/her designee, that more frequent inspections are necessary. The inspection shall incur a cost as outlined in Chapter 180, Municipal Fees. The food service facility shall allow the inspector the right of entry to areas where the grease is generated. Any reinspection shall incur an additional cost as outlined in Chapter 180, Municipal Fees. Inspections shall also be conducted when new or replacement interceptors are installed; such inspections shall incur a cost as outlined in Chapter 180, Municipal Fees. When the City performs an inspection, a record of the inspection shall be left with the food service facility. The record will note any deficiencies and recommended corrective actions.
J.
Repairs. Each food service facility shall be responsible for the cost and scheduling of all repairs to its grease interceptor(s) or traps. Any necessary repairs, as determined by an inspection, shall be completed within 14 calendar days of the written notice requiring such repairs.
K.
Food service facility FOG interceptor and trap permits.
(1)
All food service facilities, as defined in Kent County Code § 180-5, shall obtain a permit from the county and provide a copy of said permit at the facilities' expense to the City within 30 days of issuance from the county.
(2)
Records to be kept by the food service facility shall include all as-built drawings of the plumbing system, a copy of the permit, all records of inspections, the maintenance log, service receipts from grease haulers, hauler and disposal information, and any monitoring data. The file shall be made available to any authorized inspector upon request. Service and maintenance records shall be kept for a minimum of two years. Construction records shall be kept for the lifetime of the unit.
(3)
Authorized brown grease trap haulers must be registered with the State and Kent County pursuant to Kent County Code § 180-11 and must have the appropriate decal that shows they are an authorized grease hauler.
(4)
Grease traps and interceptors are not mandatory for food service facilities in existence on the effective date of this regulation who cannot physically install a grease trap or interceptor at their location, provided they apply for a permit from Kent County, have a written professional engineer's opinion that one cannot be installed, have and continue to maintain a yellow grease recycling contract and provide an emulsifier, such as a detergent or enzyme product, that keeps the grease suspended in the wastewater.
(5)
Quarterly inspections shall be conducted at a random time determined by the City to ensure that provisions of this article are being complied with. Failure to comply with the provisions of this article will result in the penalties outlined in Chapter 180, Municipal Fees.
(6)
Food service facilities with interior grease traps or interceptors must provide their own hose for the removal of the grease in the traps/interceptors. This hose must be capable of being connected to a grease hauler truck system located outside the premises.
L.
The use of food grinders in food service facility sinks is prohibited since they tend to transport FOG, and the resultant FOG can block piping and cause backups and sanitary sewer overflows, thus creating serious public health issues.
