Cincinnati restaurant FOG & grease interceptor rules
Concrete Metropolitan Sewer District of Greater Cincinnati requirements for restaurant grease traps and interceptors.
Restaurant sizing and review
Requirement: Restaurants may need a grease trap/interceptor larger than state plumbing-code requirements, potentially at least 1,000 gallons, with MSD review.
Official text: "The restaurants will be required to provide a grease trap/interceptor larger than Ohio Plumbing Code/ Ohio Administrative Code (OAC) requirements. Grease Trap/Interceptors with a minimum size of 1,000 gallons may be required. The MSD Grease Interceptor Sizing chart will be used to determine the size of the grease trap/interceptor to be installed. The entire kitchen, including dishwasher, will drain to the grease trap/interceptor. The grease trap/interceptor installation must be reviewed by MSD Development Services."
Required application records
Requirement: The owner or operator must submit the Sewer Use Customer Application and Food Service Operation form during the building-permit process.
Official text: "The Owner, Operator or Duly Authorized Representative will submit a completed Sewer Use Customer Application and a Food Service Operation form, during the building permit application process, to MSD Development Services."
Restaurant registration review
Requirement: Existing restaurants without a building permit must still register with MSD, which reviews the application and food-service form.
Official text: "CSD will also review the Sewer Use Customer Application, Food Service Form and any applicable document to register the facility in MSD database. This also applies to existing restaurants that do not require a building permit but must register with MSD. Upon completion of the review, MSD will issue a letter to the customer."
