Fat, Oil & Grease Program

Food Service Establishment (FSE) Fat, Oil, and Grease (FOG) Inspection Program
The City of Monterey is mandated by State Water Resources Control Board (SWRCB) Waste Discharge Requirements (WDRs) to prevent Sanitary Sewer Overflows (SSOs) originating from all sources, including food serving establishment (FSE) that generate fat, oil, and grease (FOG). As a result, the City has a FSE inspection program in coordination with the Source Control Team of Monterey One Water (M1W) to aid FSE FOG management citywide. 

This inspection program emphasizes responsible FSE management of FOG through the FSE’s use of grease traps and interceptors to capture FOG at the generating source, thereby helping to ensure the proper function and integrity of downstream City sewer conveyance infrastructure. Routine inspections of FSEs will occur by M1W inspectors citywide each year with three (3) main objectives - inventory existing grease pretreatment equipment to verify compliance with City and M1W FOG and plumbing standards; educate FSE owners and employees on preventing excessive FOG discharge through proper equipment maintenance and business practices; and, identify business activities that may cause pollutants to be released off-site and helping to bring awareness to protecting the environment.  

Prior to an inspection, a FSE will receive advance notice of inspection by M1W inspectors who will request to schedule and access applicable areas of the FSE business to inspect grease interceptors, traps, wastewater lines, and waste disposal areas. General questions about daily business practices and operations, equipment maintenance, and waste management may be asked during inspections, and education may be shared by M1W on these topics.

FOG Pretreatment Equipment Requirements and Fee Waiver Program
In 2007, the City adopted a fee waiver program for FSEs who demonstrate an inability to install the minimum-required grease pretreatment equipment at their place of business to comply with applicable City and M1W FOG and plumbing codes (Monterey Code Ch. 30, Article 3). The waiver fees are utilized by the City to off-set City operation and maintenance costs to regularly clear grease from City-owned sewers to prevent clogs, maintain system capacity, and ensure proper function of the City/public sanitary sewer collection system citywide. (Note: Waiver fees support the FSE FOG Inspection Program and City/public sanitary sewer collection system maintenance, only.)

Stop the Clog
Cooking fat, oil and grease (FOG) is a leading cause of sewer pipe clogs. FOGs cool and congeal on the inner walls of sewer lines and on tree roots that grow in them, much like arterial sclerosis in our bodies.
