Sewer System Management Plan
Fats, Oils, and Grease (FOG)
Chapter 10 of the California Plumbing Code provides the Building Official (or other Authorized Authority) with legal authority to require installation of interceptors (clarifiers) where waste flow conditions necessitate the proper handling of the liquid waste stream flow to protect the sewer system and the public (commonly at food service establishments, processing facilities, industrial facilities, etc., that generate grease, oil, grit, acids, alkaline or flammable wastes). This authority would apply at any facility that generates Fats, Oils or Grease in an amount that that will damage or otherwise increase the maintenance costs of the wastewater collection system.
