Fats, Oils & Grease (F.O.G.) Ordinance
The Illinois Environmental Protection Agency (IEPA) oversees and enforces regulations when a sanitary sewer overflow occurs.  Fats, Oils and Grease are a major contributor of sanitary sewer overflows when they build up in the sanitary sewer.  A sanitary sewer overflow is defined as the discharge of untreated sewage from the sanitary sewer collection system to a surface water and/or ground. 

On February 11, 2014, the Village Board passed an ordinance regulating the disposal of fats & greases; and to promote proper disposal of fats & greases and aid in preventing sanitary sewer blockages.  

Fully Executed Ordinance



WHEREAS, Chapter 25 of the Libertyville Municipal Code contains sections establishing regulations for disposal of fats and greases;

WHEREAS, in order to promote proper disposal of fats & greases and aid in preventing sanitary sewer blockages, it is necessary for the Village of Libertyville to adopt an Ordinance amending Chapter 25;


Section One: Recitals. The foregoing recitals are hereby incorporated herein as if fully set forth: 

Section Two:  Amendments to Chapter 25, Section 25-105 Interceptors.  Section 25-105 of the Libertyville Municipal Code shall be and is hereby amended with the following changes.  The current municipal code language of:  “Grease, oil, and sand interceptors shall be provided in accordance with the Illinois Plumbing Code or other sections of this Code, or, when, in the opinion of the director, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the director or the building commissioner, and shall be located as to be readily and easily accessible for cleaning and inspection” shall be deleted and replaced with the language below: 

Section 25-105 Grease, Oil and Sand Traps.  All establishments involved in the preparation of food for commercial purposes shall provide grease interceptors or traps. 

  1. Grease, oil and sand interceptors or traps shall be provided at the cost of the owner when required by the Village for the proper handling of liquid wastes containing grease in excessive amounts, sand and other harmful ingredients, except that such interceptors or traps will not be required for residential dwelling units. 
  2. All interceptors or traps shall be of a type and capacity approved by the Building Commissioner and the Illinois Department of Public Health; all such devices shall be located so as to be readily and easily accessible for cleaning and inspection.  They shall be constructed of impervious materials capable of withstanding abrupt and extreme conditions in temperatures and shall be of substantial construction, gas tight, watertight and equipped with easily removable covers. 
  3. All grease, oil and sand interceptors or traps shall be serviced and emptied at the cost of the owner on a continuous basis to maintain their minimum design capacity and the continuous efficient operation at all times.  No waste removed from the interceptors or traps shall be reintroduced into the sanitary sewer or back into the interceptor or trap, which will cause the interceptors or traps discharge to exceed sewer use ordinance limits.  The owner shall be responsible for the legally appropriate sanitary disposal of such waste.    
  4. The owner shall maintain written records of interceptor or trap maintenance and emptying interceptors and traps for the prior three years, or less, if the device is less than three years old.  Said records shall be made available upon request by the Building Commissioner or his designee.  
  5. Approval of proposed facilities or equipment by the Village Building Division, does not, in any way, guarantee that these facilities or equipment will function in the manner described by their constructor or manufacturer, nor shall it relieve any person, firm or corporation of the responsibility of enlarging or otherwise modifying such facilities to accomplish the intended purpose. 

Section Three.  That is any section, paragraph, clause, phrase or part of this Ordinance is for any reason held invalid, such decision shall not affect the validity of the remaining provisions of the Ordinance, and the application of these provisions to any persons or circumstances shall not be affected thereby.

Section Five.  This Ordinance shall be in full force and effect from and after its passage, approval and publication in pamphlet form as required by law.

DO pour fats, oils or grease into a can until they cool.  Coffee or soup cans work well.  They can be stored for reuse until fill when it can be thrown in the trash.

DO wipe pans or dishes that contain fats, oil or grease with a paper towel before washing and throw the used paper towel in the trash.

DO place a strainer in the kitchen sink drain to catch food scraps and other solids and regularly empty the strainer in the trash.

DO encourage neighbors to help keep fats, oils and grease out of the sewer system.

DO maintain an approved grease trap where food is processed.

DON’T pour cooking oil, pan drippings, bacon grease, salad dressings or sauces in the sink or toilet.  

DON’T run water over dishes, pans, fryers or griddles to wash oil and grease down the drain. 

DON’T use cloth or rags to scrape plates  or oily dishware.  When you wash them, the grease will end up in the sewer.

DON’T use a garbage disposal or food grinder on fatty or greasy food.  Grinding food before rinsing it down the drain does not remove the fats, oils or grease, it just makes the pieces smaller.  Even non-greasy food scraps (salads, etc) can plug sewer lines. 

DON’T use chemicals to remove grease clogs; they can damage the piping system
