Generators

A generator of fats, oils and grease (F.O.G.) is any person (or organization) who causes, creates, generates or otherwise produces liquid waste, or a person who, for any reason, has liquid waste removed from his property by a transporter of liquid waste. Most generators fall into one of two categories:

  • Automotive Service Establishment (ASE)
    • Examples include car wash, service station, maintenance shop
  • Food Service Establishment (FSE)
    • Examples include restaurant, bakery, food truck (mobile food unit), grocery store with deli
Chapter 38, Article VII has specific requirements to ensure proper maintenance of grease/grit traps.  For ordinance highlights relating to each type of generator, please see below.
