Why You Need a Grease Trap/Interceptor Permit
Cincinnati restaurants that discharge fats, oils, and grease (FOG) into the municipal sewer system are subject to the Metropolitan Sewer District of Greater Cincinnati (MSD) Pretreatment Program, which enforces grease discharge limits under the City's industrial pretreatment ordinance and applicable Ohio EPA regulations. Any food service establishment — including full-service restaurants, fast food operations, cafeterias, and catering kitchens — that generates FOG as part of its operations is required to install an approved grease interceptor or trap and obtain the corresponding permit before connecting to the sewer system. Operating without this permit is not a paperwork technicality: MSD inspectors conduct unannounced site visits and can identify unpermitted equipment or missing documentation during routine compliance checks. The permit requirement is also triggered when you renovate, expand seating capacity, or change your menu concept in ways that increase FOG output.
Failing to obtain or maintain a valid Grease Trap/Interceptor Permit in Cincinnati exposes your business to a compounding set of consequences that can shut down your operation entirely:
- Sewer service disconnection — MSD has authority to physically disconnect your establishment from the municipal sewer system until violations are corrected, making the restaurant impossible to operate
- Civil fines — violations of the pretreatment ordinance carry per-day fines; because fines accrue daily, a prolonged dispute can result in a significant cumulative liability (contact MSD directly to confirm current fine schedules)
- Mandatory remediation costs — if FOG discharge causes a sewer blockage, you may be held financially responsible for the cost of clearing the line and any downstream damage
- Permit revocation — a revoked permit requires a full re-application and re-inspection cycle, adding weeks or months before you can legally resume operations
- Insurance and lease complications — most commercial kitchen lease agreements and general liability policies require you to maintain all required environmental and utility permits in good standing; a lapse can trigger a lease default clause or void a claim
- Health permit jeopardy — Cincinnati Public Health coordinates with MSD on facility compliance; a grease permit violation can be flagged during your next health inspection and put your food service license at risk
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2025, MSD Greater Cincinnati has increased the frequency of FOG compliance inspections for food service establishments, with a particular focus on establishments that have not submitted required grease interceptor maintenance logs within the preceding 12-month period — contact MSD's Pretreatment Program directly to confirm your current reporting obligations before your next inspection cycle.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants generate significant fats, oils, and grease (FOG) from cooking operations and are explicitly required to install and permit a grease interceptor under Cincinnati Metropolitan Sewer District (MSD) Pretreatment Regulations, which mandate FOG control devices for any food service establishment discharging to the public sewer. |
| Bar / Nightclub | Required | Bars and nightclubs that prepare or serve food — including bar snacks, appetizers, or full menus — discharge FOG-laden wastewater and are required to obtain a grease interceptor permit under Cincinnati MSD Pretreatment Regulations; bars serving only beverages with no food preparation should contact MSD directly to confirm whether an exemption applies. |
| Food Truck | Required | Food trucks operating in Cincinnati that connect to a commissary or licensed commercial kitchen discharge point are required to manage FOG under Cincinnati MSD regulations; the truck itself must use an approved grease trap or demonstrate that all FOG waste is disposed of at a licensed grease hauler facility rather than discharged to a city sewer connection. |
| Coffee Shop / Café | Required | Coffee shops that prepare espresso, steam milk, or serve food items generate FOG from equipment cleaning and food prep and are subject to Cincinnati MSD's FOG control requirements; even light food-service operations are not automatically exempt, and operators should verify their specific discharge volume with MSD to confirm interceptor sizing requirements. |

210 of 253 auto-filledWarehouse type: Refrigerator/freezer
checkboxCheck this box if any portion of your warehouse or storage area is a refrigerated or freezer unit — this affects grease load calculations and interceptor sizing requirements.
COMMON MISTAKE: Operators often leave all warehouse type checkboxes blank when no dedicated warehouse exists; if your restaurant has any cold storage space, even a walk-in cooler, this box should be checked.
Warehouse type: Dry goods
checkboxCheck this box if your storage area holds dry, non-refrigerated goods such as canned or packaged food items, paper supplies, or cleaning products.
COMMON MISTAKE: Applicants sometimes select both 'Dry goods' and 'Refrigerator/freezer' when they have a combined storage room — selecting both is correct if the space serves both functions; do not select only one.
Warehouse type: Other
checkboxCheck this box if your warehouse or storage space does not fit the refrigerator/freezer or dry goods categories — for example, a chemical storage or equipment staging area.
COMMON MISTAKE: Selecting 'Other' without providing a written description in the associated notes field (if present) can trigger a reviewer request for clarification, adding processing time.
Location: Strip Mall (attached)
checkboxCheck this box if your food service facility is located inside an attached strip mall — meaning it shares at least one wall with adjacent tenant spaces in a connected retail row.
COMMON MISTAKE: Confusing a detached strip mall outparcel (which qualifies as 'Stand-alone Restaurant') with an attached strip mall unit is a common error that misrepresents your shared-drainage configuration.
Location: School
checkboxCheck this box if your food service operation is located within a K–12 school, college, or university campus facility.
COMMON MISTAKE: Operators in school-adjacent commercial buildings sometimes mistakenly check this box; only check it if your kitchen is physically housed within the school's structure or on school property.
Location: Stadium/Amusement Park
checkboxCheck this box if your food service operation is inside a stadium, arena, or amusement/theme park facility — these venues typically have high-volume grease output that affects interceptor sizing.
COMMON MISTAKE: Operators in entertainment districts near stadiums sometimes check this box in error; it applies only to kitchens physically located inside the venue structure.
Location: Supermarket
checkboxCheck this box if your food service facility operates within a supermarket or grocery store — this includes deli counters, in-store bakeries, and prepared food stations inside a grocery retail environment.
COMMON MISTAKE: A standalone restaurant that happens to be adjacent to a grocery store should not check this box — it applies only to food prep operations that are part of the supermarket's own operations.
Location: Stand-alone Restaurant
checkboxCheck this box if your restaurant occupies a freestanding building with no shared walls — this is the most common selection for independent full-service restaurants in Cincinnati.
COMMON MISTAKE: Restaurants in outparcels with shared parking but no shared walls often qualify as stand-alone, but operators in end-cap strip mall units (which share at least one wall) incorrectly select this option instead of 'Strip Mall (attached),' which can cause your interceptor sizing calculation to be flagged for review.
Location: Mall/Food Court
checkboxCheck this box if your food service operation is located inside an enclosed shopping mall or a designated food court area — these settings often share a common grease interceptor system with other tenants.
COMMON MISTAKE: If your mall location uses a shared interceptor managed by the property owner rather than your own dedicated unit, this distinction must be accurately reflected here; misclassifying as 'Strip Mall (attached)' can result in incorrect interceptor size requirements being assigned to your permit.
Location: Nursing Home
checkboxCheck this box if your food service operation is the kitchen for a licensed nursing home, assisted living facility, or long-term care center.
COMMON MISTAKE: Operators running a restaurant that leases space inside an assisted living complex should not check this box unless the kitchen primarily serves the facility's residents as its core function.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting Incorrect or Outdated Device Specifications
The most common rejection trigger is listing a grease interceptor model or capacity that doesn't match MSD's approved equipment list or Cincinnati Plumbing Code requirements. For example, submitting a 500-gallon passive interceptor spec when your kitchen's grease-producing fixture count requires a minimum 1,000-gallon unit will result in immediate rejection. Before submitting, cross-reference your proposed device against MSD's current approved interceptor list and confirm sizing with a licensed plumber using the fixture-unit calculation method required by the Ohio Plumbing Code. This mistake typically adds 2–4 weeks to your timeline while you source a compliant unit and revise your drawings.
2. Missing or Non-Compliant Plumbing/Site Plans
MSD requires stamped, to-scale plumbing drawings that show the interceptor's exact location, inlet/outlet piping, cleanout access points, and distance from the public sewer connection — a freehand sketch or architectural floor plan without plumbing details will not be accepted. A common example: submitting a general floor plan that shows the grease trap location but omits the required 6-inch cleanout detail or the venting configuration. Engage a licensed Ohio plumber or mechanical engineer to prepare compliant drawings before you apply; incomplete plans are the second-leading cause of rejection and can add 3–5 weeks while revised drawings are prepared and resubmitted.
3. Entering the Wrong Facility or Business Classification
MSD classifies food service establishments by type (full-service restaurant, fast food, cafeteria, commissary, etc.), and each classification carries different sizing and maintenance frequency requirements — misclassifying your operation leads to a permit issued for the wrong interceptor size or pumping schedule, which can trigger compliance violations at your first inspection. For instance, listing your ghost kitchen as a 'cafeteria' instead of a 'commercial kitchen/commissary' can result in an undersized unit that fails your pre-opening MSD inspection. Verify your correct MSD facility classification before completing the form; if uncertain, contact MSD's Industrial Pretreatment program directly at (513) 352-4900 to confirm. This error, caught at inspection rather than submission, can delay your Certificate of Occupancy by 2–3 weeks.

Determine Grease Trap/Interceptor Requirements
Contact the Cincinnati Department of Transportation & Engineering (DOTE) or your local plumbing inspector to confirm whether your restaurant requires a grease trap or grease interceptor based on your kitchen layout, equipment, and wastewater volume. Request the specific size and type required — undersized traps are the #1 reason for permit rejections. Have your restaurant's square footage, number of fryers/grills, and existing plumbing documentation ready. This step clarifies whether you need a permit at all.
Obtain or Prepare Installation Plans
If you don't already have one, hire a licensed plumber or engineer to prepare a grease trap/interceptor installation plan showing location, size (in gallons), connection points to your kitchen drains, and compliance with Cincinnati plumbing code. Cincinnati requires plans to show compliance with Ohio Plumbing Code Chapter 4101:1-15 and local ordinances. Submit this plan with your permit application — plans missing capacity calculations or connection diagrams cause 2-3 week delays.
Complete and Submit Permit Application
Fill out the Cincinnati Grease Trap/Interceptor Permit application (available from DOTE or online) with your restaurant's name, address, owner/operator contact info, equipment details, and the approved installation plan. Submit the application along with proof of business registration or occupancy permit. Government filing fees for this permit typically range from $50–$150, depending on trap size and installation complexity — verify the current fee with DOTE before submitting. Most applicants submit in person at the DOTE office (1000 Broadway, Cincinnati, OH 45202) or by mail; confirm current submission methods with the department.

See All RequirementsProcessing time varies depending on whether your application is complete and your grease trap system meets Cincinnati's specifications — contact the Cincinnati Department of Public Services (DPS) Wastewater Division to confirm current timelines, as they process applications on a case-by-case basis. Incomplete applications or systems requiring modifications typically add 1–2 weeks to approval. Once approved, you can schedule your inspection, which is a separate step in the permitting process.
Cincinnati does not charge a separate filing fee for grease trap/interceptor permits — government filing fees are $0–$0 per the Cincinnati Department of Public Services fee schedule. However, you may incur costs for required equipment installation, system sizing calculations, or modifications to meet city code standards; contact the DPS Wastewater Division to confirm any associated compliance expenses. If your system requires a Backflow Prevention Device Certification, that may involve additional fees from your certified tester. Not legal advice — verify current fees with the Cincinnati DPS.
No — grease trap/interceptor permits are location-specific and tied to the restaurant's physical address and drainage system, so you cannot transfer a permit to a new location. If you relocate, you will need to apply for a new permit at your new address and have your system inspected to comply with Cincinnati's requirements. Contact the Cincinnati Department of Public Services Wastewater Division for the new location application process.
Renewal frequency depends on Cincinnati's permit cycle and your maintenance compliance — contact the Cincinnati Department of Public Services Wastewater Division to confirm the specific renewal schedule for your permit. Most jurisdictions require annual or biennial inspections and maintenance records to keep the permit active, and you must also maintain a valid Business Tax Registration Certificate to operate. Failure to renew on time may result in fines or shutdown orders.
During the inspection, a Cincinnati Department of Public Services inspector will verify that your grease trap/interceptor system is properly sized, installed, and maintained according to local plumbing and wastewater codes — they will check for leaks, proper access points, and correct discharge connections. The inspector will also review your maintenance records and cleaning schedule to ensure compliance with the city's requirements. If your system fails inspection, you will need to make corrections and request a re-inspection before your permit is finalized.
