Columbus Grease Trap Requirements for Restaurants

Columbus Local Grease Trap Regulations

The Columbus Department of Public Health requires all food service establishments to install and maintain grease traps or interceptors sized according to peak flow rates and fixture drain connections. Restaurants must obtain a food service license, which includes inspection of grease management systems. Columbus Code Title 3535 specifies that interceptors must be accessible for cleaning and inspection, typically located outside the building or in designated utility areas. The city requires documentation of maintenance contracts and pump-out records from certified providers. Inspectors verify compliance during routine health inspections and can issue violations for improperly sized, blocked, or unmaintained systems.

Ohio Department of Health Standards vs. Federal Requirements

Ohio's plumbing code (based on the International Plumbing Code) mandates grease interceptor sizing based on the Fixture Drain Unit (FDU) method, which differs from federal standards that primarily focus on food facility documentation. The Ohio Department of Health does not set specific FOG discharge limits—instead, municipalities like Columbus establish local discharge thresholds typically not exceeding 100 mg/L of grease in wastewater. Federal standards under the Clean Water Act focus on pretreatment and municipal sewer system protection rather than prescribing individual trap sizes. Ohio requires monthly cleaning for most commercial kitchens, while Columbus inspectors may enforce more frequent pumping (every 2–4 weeks) based on facility size and cooking volume.

Maintenance, Inspection, and Compliance Documentation

Columbus restaurants must maintain daily records of kitchen cleaning practices and quarterly documentation of professional grease trap pump-outs by licensed waste haulers. The city's health department conducts announced and unannounced inspections to verify trap functionality, checking for blockages, overflow, and proper labeling. Non-compliance results in violations, fines ranging from $100–$500 per infraction, and potential license suspension if violations persist. Restaurants should schedule maintenance before grease levels reach 25% of trap capacity to prevent overflow into municipal sewer lines. Panko Alerts monitors Columbus health department inspection databases and regulatory updates, notifying restaurants of requirement changes or enforcement actions affecting their permits.
