FOG is the acronym used to refer to Fats, Oils and Grease that enter the sewer system from homes, apartments, restaurants, and industry and public facilities. As a byproduct of cooking, FOG is usually found in:

• Baking goods
• Butter, lard, shortening
• Cooking oil
• Fats and oil from cooked meats
• Food Scraps
• Gravy
• Mayonnaise
• Salad Dressings
• Sauces
• Sour cream

FOG can be classified into two different categories: residential FOG and commercial FOG.

Why is FOG an issue for me?

When FOG are poured down drains or in garbage disposals, they build up in our sewer systems and can back up in homes or manholes. These backups and overflows pose serious public health and environmental problems. Additionally, FOG increases the existing financial cost associated with the operation and maintenance of the sanitary sewer system.

EPA’s Report to Congress on combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) identified that “grease from restaurants, homes, and industrial discharges into sources are the most common cause (47%) of reported blockages. Grease is problematic because it solidifies, reduces conveyance capacity, and blocks flow.”

By learning how to safely recycle or dispose of FOG, we are improving the health of our environment and the quality of life in our community.
