In addition to all other sections of this chapter, the following special provisions apply to establishments required to provide a grease trap including, but not limited to, CFE. Grease trap maintenance: over 50 gallons. Grease trap maintenance is critical to the grease trap's performance. Each CFE is required to maintain the grease trap in satisfactory operating condition by the periodic removal of the entire contents of the grease trap. All costs for inspections, pumping, sampling, analysis, or other maintenance is the responsibility of the CFE owner or operator.

Property owners of commercial properties are responsible for the installation and maintenance of a grease trap that serves multiple CFEs that are located on a single parcel or development. To ensure that the grease trap is working as it was designed, the following maintenance procedures are required for grease traps over 50 gallons: Content removal. Maintenance must include the complete removal of the entire contents, including floating materials, wastewater, settled solids and grease accumulated on the side of the device. Decanting or discharging of removed waste or wastewater back into the grease trap from which the waste or wastewater was removed or any other grease trap for the purpose of reducing the volume to be disposed of is strictly prohibited.

No FOG that has accumulated in a grease trap is allowed to pass into any sewer lateral, sewer system, storm drain, or public right-of-way during maintenance activities. Maintenance frequency. All grease traps must be pumped out completely by a permitted waste hauler whenever the accumulation of grease and solids is 25% of the grease trap's overall liquid depth or at least once every 90 days, whichever is more stringent. Exception to this minimum frequency of pumping may be made with special written approval from the Town for generators of small quantities of grease waste.

In no case will the frequency of pumping be less than once every six months. Prohibition of additives. The introduction of additives such as bacteria, enzymes, emulsifiers, or similar chemicals designed for the purpose of emulsifying or controlling FOG discharge into grease traps or associated plumbing is strictly prohibited. Septage hauler.

All CFEs must ensure that all recovered contents of the grease trap be removed and disposed of by a permitted septage hauler. Self-cleaning grease trap maintenance: under 50 gallons. Proper on-site material disposal methods shall be demonstrated and implemented (e.g., absorb liquids into solid form and dispose into trash, and collected grease is transported by a permitted septage hauler). The grease and floatable solids must be removed a minimum of once a week, and the entire contents of the grease trap is removed from the grease trap and baffles at a minimum of once every 30 days.

All records of grease trap self-cleaning maintenance must be handwritten with permanent ink and logged. Grease trap self-cleaning maintenance logs must include, at a minimum, the date and time of cleaning, total gallons removed, method of disposal, and the name of the person witnessing the cleaning. The maintenance logs must be readily available for inspection and retained on site for a minimum of three years. Best management practices.

Use absorbents to soak up spills containing fats, oils, and grease. Do not put food (including liquid food), including, but not limited to, milkshakes, syrups, batters and gravy down the drain. Use strainers on sinks and floor drains to prevent solid material from entering the sewer system. Post "No FOG" signs near sinks and drains.

If you have an automatic grease recovery device, empty the collection pan before it becomes full. Provide your employees with the proper equipment for cleaning your grease trap/interceptor or grease recovery device. Train all kitchen staff in the best management practices for FOG disposal and the impacts of FOG accumulation in the sewer system. Provide regular refresher training/discussion for proper disposal of fats, oils, and grease for all employees.
