All food service establishments that serve or prepare food or any other establishment from which a considerable amount of F.O.G. may be introduced to the sewer system shall have an adequate grease removal system installed and/or exercise proper kitchen best management practices to ensure that excess concentrations of F.O.G. are not discharged to the POTW. Take-out food establishments or other establishments that prepare food, but do not cook in oil or grease, and who serve food only in disposable containers, may be exempted from this requirement, provided their discharges will not violate the general discharge prohibitions of this chapter.

These pretreatment facilities must be approved grease removal systems installed in the waste line leading from sinks, drains, or other fixtures where F.O.G. may be discharged. The grease removal systems must meet, at a minimum, the specifications of the current Uniform Plumbing Code as adopted by the city at the time of construction. Dischargers must maintain these systems in a manner that will always prevent fat waste, oil or grease from being carried into the sewer system. Fat waste, oil or grease removed from such a system shall not be disposed of in sanitary or storm sewers.

Containment of fats, oils and grease shall be in approved containers and the surrounding area clean of any residue. Containers shall be inside a covered enclosure that is kept clean and capable of containing any and all spillage from the containers. The director may grant a variance on the type or size of grease removal system required as deemed appropriate under extraordinary circumstances.
