Frequently Asked Questions

What is FOG?
FOG is an acronym for Fats, Oils, and Grease which is commonly found in wastewater.

What causes FOG?
FOG is the leftover grease from cooking, food, drink preparation, and meat cutting. FOG can be found in meat fats, shortening, butter, margarine, sauces, and dairy products.
  • "Yellow" grease: inedible and unadulterated spent FOG, removed from FSE. The major source of yellow grease is deep frying. Put this type of grease in the grease recycle bins, normally found at the back of the FSE.

  • "Brown" grease: floatable FOG, settled solids and associated wastewater retained by grease interceptors and grease traps.
Why are coffee shops included in the mandate for a BMP?
Coffee shops are included in the program because of the oils in coffee beans and the dairy products used to produce the coffee. Coffee beans contain 15% oil per bean and the dairy products have 3% milk fat content per ounce of milk product

Why is FOG a problem?
Fats in wastewater are among the more stable of the organic compounds and are not easily decomposed by bacteria so these fats coat, congeal, and accumulate on pipes, pumps, equipment and sometimes obstruct lines.

What will the inspectors be looking for?
The City FOG inspectors will inspect the sewer system for FOG accumulation. They will verify that the food service establishment has implemented and is adhering to a Fats, Oils and Grease Best Management Plan for controlling FOG. They will check to see if you have a "written" FOG/BMP with supporting documents including grease interceptor cleaning logs and waste manifests.

What can be done to stop FOG?
Control FOG at the source - keep it from entering the sewer system.
  • Best management practices (BMPs) can go a long way toward reducing FOG in the sanitary sewer system.

  • Use pretreatment like grease traps or interceptors, skimmers, separators, and process flow treatment systems, such as carbon filtration or coagulation units.

What is a grease trap and how does it work?
A grease trap is a small reservoir built into the wastewater piping, a short distance from a grease producing area. Baffles in the reservoir retain the wastewater long enough for the grease to congeal and rise to the surface. The grease can then be removed and disposed of properly. See a typical grease trap diagram below.



What is a grease interceptor and how does it differ from a trap?
The term grease interceptor can refer to any type of wastewater pretreatment device used for the purpose of collecting and storing fats, oils, or grease before that water reaches the sewer. It can also refer to a type of grease trap that is larger and slightly more complex than a standard device.

A grease interceptor is a vault located on the outside of the building. The capacity of the interceptor, usually a minimum of 500 to 700 gallons, allowing the remaining grease, not collected by the traps, time to congeal and rise to the surface. The grease accumulates here until the interceptor is cleaned. The figure below illustrates a typical grease interceptor.



How can I get my business in compliance?
Maintain a FOG BMP Compliance Program. Our program provides training, instructions and all of the proper forms to satisfy the mandate for compliance.

If your business does not have a grease interceptor, and you produce fats, oils and grease, you will need to install one.

If you have a grease trap or interceptor and believe that it may be ineffective at keeping FOG out of the sanitary sewer (i.e. needs frequent cleaning, backups occurring in kitchen, etc.), you may need to upgrade or replace your existing grease trap/interceptor.
