FOG Control Program Manual 1.0 INTRODUCTION City of Santa Ana's (City) Fats, Oils, and Grease (FOG) Control Program has been developed to prevent FOG -related sanitary sewer overflows (SSOs) as required by the Santa Ana Regional Water Quality Control Board (SARWQCB) General Waste Discharge Requirements (WDR), Order No. 2006-0003-DWQ. This order was issued in response to a State SSO problem and was issued to all sewer agencies in California with a public sewer system greater than 1 mile, which included local agencies, such as cities and special districts, in the northern and central portions of Orange County. The FOG Control Program's goal is to eliminate all FOG -related SSOs. These SSOs are usually attributable to cooking grease in wastewater discharged from Food Service Establishments (FSEs)', multi -family housing, and single family homes that create FOG (or grease) blockages in sanitary sewer collection systems. These grease blockages, located in either the property owner's sewer lateral or the sanitary sewerage system, lead to SSOs, which can cause untreated sewage to flow onto streets and travel to storm drains, creeks, and other surface waters. Untreated sewage on private property or in the street poses an obvious human health risk. If this sewage reaches the ocean, it often results in coastal contamination, beach closures, and the associated potential human health risks. To achieve this goal of eliminating FOG -related SSOs, the WDR has identified key requirements for a FOG Control Program, which are as follows: • Limit grease discharges that may cause blockages; • Prohibit FOG discharges that may cause sewer overflows; • Adopt and enforce a FOG ordinance; • Require implementation of kitchen best management practices (BMPs); • Require installation of grease removal equipment, as necessary; • Inspect FSEs; and • Implement source control measures for sewer line "enhanced maintenance locationsz". These requirements are the key issues that were addressed in the development of the City's FOG Control Program. Food Service Establishments (FSEs) are those establishments primarily engaged in preparing or serving food to the public such as restaurants, hotels, commercial kitchens, bakeries, caterers, schools, prisons, correctional facilities, and care institutions. 2 Known problem areas in the sanitary sewer system that requires more frequent cleaning and maintenance. 19F-182 i
