Fats, Oils & Grease (FOG)

About Fats, Oils and Grease (FOG)

FOG is one of the leading causes of sewage backups and overflows, leading to costly cleanup costs and environmental problems impacting both residential homes and commercial businesses. Implementing FOG Best Management Practices (BMPs) reduces or eliminates the likelihood of issues in the City’s sewer lines, thereby, safeguarding businesses and homes from the impact of sewage backups and overflows.

Common sources of fats, oils and grease:

  • Butter
  • Cooking Oil
  • Grease
  • Food scraps
  • Lard
  • Margarine
  • Meat scraps
  • Shortening


For residential buildings, the prevention of fats, oils and grease is up to the individual. Some of the BMPs to safeguard against the buildup of FOG are as follows:

  • Recycle waste cooking oil.  Never pour oil down sinks or drains.
  • “Dry Wipe” pots, pans and dishware prior to washing.
  • Dispose of food waste by recycling and/or solid waste removal.

Residential Fats, Oils and Grease Information

For commercial businesses, a grease separation device (GSD), along with various other BMPs, shall be required dependent on user type.

FAQs for Food Service Establishments

What does this mean for my business?
What do I need to do?

All FSEs are required to install and maintain a grease separation device (GSD). The size and location of the GSD is dependent on user type. For more information, please contact Ryan Lipp at 704-920-4285.

Where can I find the city’s requirements for FOG?
What if I do not have a GSD?

Please contact Ryan Lipp at 704-920-4285 for guidance on bringing your establishment into compliance.

What, if any, paperwork is required?

The City of Kannapolis requires that the FSE keep written record of all GSD maintenance for three (3) years. To do this, the City of Kannapolis utilizes an online software program that allows users to submit all documents electronically. This program is also where users will receive updates on any inspections done at their facility.
