Paso Robles Municipal Code Art. V Fats, Oils and Grease Control Program

The city fats, oils and grease (FOG) control manual shall be used for determining the sizing of new or replacement grease control devices (GCDs) and for maintenance of all GCDs at food service establishments (FSEs).

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

Article V shall apply to all commercial FSEs such as: food or meat processing, commercial kitchens, including, but not limited to, restaurants, food courts, bakeries, catering services, grocery stores, hotels, cafeterias, churches, hospitals, nursing homes, daycares, assisted living facilities and other healthcare facilities, residential kitchens with home business and mobile food units. A FOG generator also includes any of the above businesses that produce used cooking oil or can introduce food waste or FOG into sanitary sewer systems.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

Any IU, other than FSEs, that have the potential to generate oil and grease, including, but not limited to, repair shops, manufacturing, maintenance activities shall comply with Article VII, subsection 14.10.450.D. of this chapter.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

Any substance discharged into the city's sewer system that will accumulate or cause or contribute to blockages in the city's sewer system or in a sewer lateral that connects an FSE to the city's sewer system is prohibited. Garbage grinders and dishwashers shall not be connected to a GCD.

The introduction of additives such as bacteria, enzymes, emulsifiers, or similar chemicals designed for the purpose of emulsifying or controlling FOG discharge into a GCD or associated plumbing is prohibited.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

FSEs that serve or prepare food where FOG may be introduced into the sewer system shall install an approved GCD to prevent the discharge of FOG. The GCD shall meet either the third party approvals or the specifications of the current California Plumbing Code adopted by the city at the time of plan approval depending on the type of GCD to be installed.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

An FSE that serves food that is not cooked on-site may be exempt from this requirement. Written approval from the director must be obtained. The discharge must not violate the discharge prohibitions cited in Sections 14.10.040.B.—14.10.060 and the local limits cited in subsection 14.10.070.B.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

All plumbing fixtures with potential to discharge grease-laden waste located in food and beverage preparation areas must be routed through a GCD. The fixtures include, but are not limited to: preparation (prep) sinks, pre-rinse sinks, pot sinks, three-compartment sinks, hand sinks, floor sinks, mop sinks, drains from washdown ventilation hoods, and any other fixtures that can contribute FOG via floor and trench drains (e.g. wok stations, pasta stations).

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

A. GCDs must be pumped/cleaned out completely a minimum of once every ninety days or when the twenty-five percent rule is reached, as defined in the FOG control manual, whichever is sooner.

B. FSEs requiring the use of a GCD shall implement BMPs to reduce grease per the FOG control manual.

C. If the city finds that a GCD or gravity separating device installed prior to the effective date of the ordinance from which this chapter derived is incapable of adequately retaining the grease, sand, or oil in the wastewater effluent, as the case may be, an adequate GCD or gravity separating device shall be installed at the owner's expense within the time period specified by the city.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)

An FSE shall have its GCD pumped out and thoroughly cleaned if the business is to be permanently closed. It is the responsibility of the property owner to have the GCD pumped out if not done by the FSE. GCDs shall be removed or abandoned in place if the facility is demolished or the use of the building will not require a GCD.

(Ord. No. 1105 N.S., § 2 (Exh. A), 12-1-2020)
