If you operate a restaurant, food truck, school cafeteria, or any commercial kitchen in Toledo, Ohio, you are enrolled in the Toledo FOG (Fats, Oils & Grease) Program whether you know it or not. The program is mandatory, it’s enforced, and the Toledo Waterways & Water Services has gotten more aggressive about compliance inspections in recent years.
Note: Specific code references, fine amounts, and inspection requirements in this article are provided for general guidance only. Regulations can change — always verify current requirements with the City of Toledo or a licensed compliance professional before making decisions for your business.
This guide explains what the FOG program actually requires from you, how the inspection process works, and what most restaurant owners miss the first time they go through it.
What Is the Toledo FOG Program?
FOG stands for Fats, Oils, and Grease — the byproduct of commercial cooking that enters your plumbing when you cook, wash dishes, or clean kitchen equipment. When FOG enters the City of Toledo’s sewer system in sufficient quantities, it solidifies on pipe walls, causes blockages, and eventually creates sewer overflows that the EPA classifies as a sanitary sewer overflow (SSO) — a significant environmental violation.
To prevent this, the City of Toledo administers a pretreatment program under authority of the Clean Water Act Section 307 and Ohio Administrative Code 3745-33. All food service establishments (FSEs) generating FOG are required to install, maintain, and service grease interceptors or grease traps and document that maintenance with the Toledo Waterways & Water Services.
What the Program Actually Requires You to Do
- Install an approved grease interceptor or trap — sizing must comply with the International Plumbing Code and be approved by Toledo’s Division of Building Inspection
- Service your trap before it reaches 25% capacity — the fill level of grease and solids combined cannot exceed one-quarter of the trap’s total hydraulic volume
- Use a licensed waste hauler — grease waste is regulated under Ohio EPA and cannot be disposed of in dumpsters, on-site, or in municipal water
- Maintain a service log — the city can request your service records going back 3 years during an inspection
- Provide waste manifests — your service provider must issue a manifest documenting volume removed, time, and disposal destination
How Toledo FOG Inspections Work
The Toledo Waterways & Water Services coordinates FOG inspections with the Lucas County Health Department. Inspections can happen during a routine health inspection, in response to a reported sewer backup, or as a standalone FOG compliance audit. There is no guaranteed advance notice for compliance inspections.
During an inspection, the inspector will:
- Request your service log and waste manifests
- Visually inspect the grease trap access lid and condition
- May probe the trap to measure current fill level
- Check that the trap is the correct size for your fixture count
- Verify your service provider is a licensed waste hauler
The most common violation we see cited in Toledo is missing or incomplete documentation — not an overloaded trap, but a restaurant that had the work done but couldn’t produce the paperwork. A verbal assurance that you “just had it cleaned last month” carries no weight with a Lucas County Health Department inspector. The manifest is the record.
Grease Interceptors vs. Grease Traps Under the FOG Program
The program covers both grease traps (small, indoor, under the sink) and grease interceptors (large, outdoor, in-ground tanks). The type required for your establishment is determined by your total fixture units and flow rate, not by preference.
Most full-service restaurants in Downtown Toledo and established dining corridors in Maumee and Sylvania will require an outdoor grease interceptor. Smaller operations — food carts, small cafés, limited-service businesses — may qualify for an indoor grease trap. If you’ve never confirmed which type your establishment is supposed to have, a plumbing permit inspection record or a call to Toledo’s Division of Building Inspection will tell you.
Common Violations and How to Avoid Them
After servicing hundreds of Toledo restaurants, these are the violations we see most often during FOG inspections:
- Missing manifests — the most common. Always get paper documentation from your service provider, every visit
- Trap oversaturated at inspection — usually from a restaurant that stretched the interval too far during a busy season
- Unapproved service provider — make sure your hauler is licensed in Ohio and pulls proper waste permits
- Trap too small for current fixture count — common in restaurants that expanded their kitchen without upgrading the interceptor
- Baffle or lid damage — deteriorated baffles allow grease to pass into the sewer, which the city can detect through sewer monitoring
Every service call we do includes a written waste manifest and a condition report on the trap itself. If we find a baffle issue or a lid that isn’t sealing correctly, we document it so you have a paper trail showing you identified and are addressing the problem — which matters if a violation is cited.
Frequently Asked Questions

Yes. Mobile food service units operating within Toledo are subject to FOG requirements and must manage grease waste through approved disposal at licensed facilities. Many food truck operators arrange service with commissary kitchens that handle FOG compliance on their behalf.
You’ll receive a written notice of violation and a deadline to achieve compliance — typically 30 days for documentation issues, immediately for an overloaded trap. Fines start at $250 and escalate to $5,000 per incident. Repeat violations can trigger mandatory closure until the violation is cleared.
If you generate any cooking grease — even from a small fryer or grill — you likely fall under the FOG program. The threshold is based on fixture units, not business size. Contact Toledo’s Division of Building Inspection with your fixture count to confirm your requirements.
Toledo inspectors can request up to 3 years of service records. Keep all waste manifests and service reports organized by date. Digital copies are acceptable as backup, but printed manifests from your service provider are the standard documentation.
Enzyme and biological treatments are not accepted substitutes for mechanical grease traps or interceptors under the Toledo FOG program. These additives break grease into smaller molecules that still enter the sewer system — they do not remove FOG from the waste stream. Only mechanical removal and documented disposal satisfies the program requirements.
