Why You Need a Grease Trap/Interceptor Permit
Operating a food service establishment in Eugene without a properly permitted grease interceptor is a direct violation of the city's utility code and public health protections. The primary legal authority is the Eugene Municipal Code (EMC) Title 3, Chapter 7, Sewer Use, which mandates that any business producing grease-laden wastewater must install and maintain an approved interceptor to protect the public sewer system. Additionally, your water/sewer service connection agreement with the City of Eugene Public Works Department specifically requires this permit as a condition of service, and your facility's plan review under the Oregon State Plumbing Code (Oregon Specialty Code, Chapter 10) will not be finalized without it. This is not a single regulation but a layered requirement tying your occupancy, utility service, and plumbing system approval together.
The practical consequences of non-compliance are immediate and costly. The City of Eugene Public Works – Environmental Services Division actively enforces these rules, and violations can lead to:
- Immediate service disconnection: The city can terminate your water and sewer service, effectively shutting down your business until the violation is corrected.
- Substantial fines and remediation costs: You will face daily fines for the violation itself, plus be required to pay for any required clean-up of the public sewer line, which can cost thousands of dollars.
- Permit revocation and delayed openings: Your overall building or business license can be suspended, and any new project approvals will be frozen until the grease interceptor issue is resolved, adding weeks or months to your timeline.
- Insurance and lease implications: Many commercial property insurance policies and leases have clauses that void coverage or constitute a lease default if you operate in violation of municipal code, exposing you to significant personal liability.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: In 2026, the City of Eugene Public Works Department introduced enhanced digital inspection tracking for grease interceptors, requiring permit holders to submit maintenance logs and pump-out receipts directly through the city's online portal to maintain compliance.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | All establishments that prepare food and produce grease-laden wastewater are required to install an approved grease interceptor or trap, per Eugene's Municipal Wastewater Management Ordinance (MWMO). |
| Bar / Nightclub | Required | Required if the facility has any food preparation, dishwashing, or bar sink with a drain connection, as grease from food waste or cleaning enters the sanitary sewer system. |
| Food Truck | Not Required | Typically operates from a commissary kitchen where the interceptor is installed; the mobile unit itself requires a separate Mobile Food Unit (MFU) permit focused on waste holding tanks, not a city grease interceptor permit. |
| Coffee Shop / Café | Required | Required if the shop has a food preparation sink, dishwasher, or equipment for making food items that produce fats, oils, and grease (FOG). |

16 of 19 auto-filledBusiness Name
textEnter the exact, full legal name of your business as registered with the Oregon Secretary of State, which must match your business license and health department application.
COMMON MISTAKE: Using a DBA or 'doing business as' name instead of the registered legal entity name, which can cause a mismatch with city records and delay processing.
Business Physical Address
textEnter the complete street address of the restaurant facility where the grease trap will be installed, including suite or unit number if applicable.
COMMON MISTAKE: Entering a P.O. Box or mailing address instead of the physical location, which prevents the city from verifying the property for inspection and zoning.
Responsible Party Name and Contact Information
textProvide the full name, title, daytime phone number, and email address of the person legally responsible for the permit and facility compliance (typically the owner or general manager).
COMMON MISTAKE: Listing an employee without authority to sign permits or failing to provide a direct phone line, which stalls communication for inspections and corrections.
Type of Food Service Establishment
textSpecify your primary operation, such as 'full-service restaurant', 'fast food', 'cafeteria', 'bakery', or 'catering kitchen', as defined in Eugene Code Chapter 7.
COMMON MISTAKE: Using generic terms like 'restaurant' instead of the specific city classification, which determines your grease trap sizing requirements and can lead to an undersized permit.
Description of Wastewater Discharge Practices
textDescribe all sources of grease-laden wastewater, including dishwashing, floor drains, prep sinks, and cooking equipment drains, and your current disposal methods.
COMMON MISTAKE: Omitting a major discharge point (e.g., a wok station drain or mop sink), which constitutes an incomplete application under Eugene Wastewater Regulations and triggers a request for additional information.
Has Current Grease Removal Equipment
checkboxCheck 'Yes' if any existing grease interceptor, trap, or separator is currently connected to your plumbing, even if it is non-compliant or needs replacement.
COMMON MISTAKE: Incorrectly checking 'No' when an old trap exists, which misrepresents the site conditions and can invalidate the permit after an inspector's site visit.
Current Grease Removal or Pretreatment Equipment Description
textIf you checked 'Yes' above, describe the make, model, capacity (in gallons), location, and current condition of all existing grease control devices.
COMMON MISTAKE: Leaving this field blank after checking 'Yes', which the Eugene Public Works Department flags as an incomplete response and requires a correction before review.
Has Control Access Hole for Inspection
checkboxCheck 'Yes' only if a dedicated, unobstructed manhole or access port (minimum 20-inch diameter) exists for city staff to sample and inspect the interceptor.
COMMON MISTAKE: Checking 'Yes' for a standard cleanout plug, which does not meet the access requirement and will fail the initial inspection, requiring costly modification.
Needs New Grease Removal Device Installation
checkboxCheck 'Yes' if this application is for installing a new grease interceptor or trap, or replacing an existing one that does not meet current city standards.
COMMON MISTAKE: Confusing this with a maintenance permit; checking 'Yes' here requires you to complete the planned equipment specs and may trigger a separate plumbing permit review.
Planned Grease Removal Device or Interceptor Specifications
textIf a new installation is planned, provide the manufacturer, model, rated flow rate (GPM), liquid capacity (gallons), and the proposed location on the property.
COMMON MISTAKE: Providing only capacity without the flow rate, or specifying a model not approved for use in Eugene, which results in a rejection until compliant specs are submitted.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Underestimating Trap Size Capacity (GPM)
Selecting a grease trap/interceptor with a gallons-per-minute (GPM) flow rate lower than your actual fixture discharge, as calculated per Eugene Public Works Engineering Design Standards Chapter 5. This triggers an automatic plan review rejection, as the system is deemed insufficient. Correctly size your trap by totaling the drainage fixture units (DFUs) from all kitchen sinks, dishwashers, and prep sinks, then using the city's sizing tables. A common mistake is using the trap's physical gallon capacity instead of its rated GPM flow rate, which adds 3-4 weeks for revised plans and a second review cycle.
2. Omitting the Plumbing Contractor's License Details
Failing to provide the name, license number, and signature of the Oregon-licensed plumbing contractor who will install the device. The City of Eugene's Pretreatment Program requires this verification to ensure code-compliant installation. Applications submitted without this are held as incomplete. Avoid this by securing your plumbing contractor before applying and having their State of Oregon Construction Contractors Board (CCB) license number ready. This omission typically causes a 1-2 week delay while you track down the information and resubmit.
3. Incorrectly Mapping the Grease Trap Location
Providing a site plan that doesn't clearly show the grease trap's location relative to the building, property lines, and public sewer lateral. Or, placing the trap in an inaccessible location (e.g., under a concrete pad, in a locked basement). Eugene requires clear access for city inspectors to perform mandatory maintenance inspections. Submit a scaled site plan with the trap marked, and ensure the proposed location has at least 3 feet of clearance on all sides. An inaccessible location note from an inspector can force a costly re-installation, delaying your final approval by a month or more.

Complete the General Requirement application form (Document No. ISC-143)
Fill out all sections of the City's official ISC-143 form, which covers business details, grease trap specifications, and wastewater discharge estimates. You'll need your site's plumbing plans, grease interceptor model/size details, and the Standard Industrial Classification (SIC) code for your business. The City’s Industrial Pretreatment Program states incomplete wastewater characterization data is the most common reason for rejection, requiring a full re-submission. Duration: 2–3 hours to gather information and complete.
Install suitable grease removal device (interceptor) if not already present
Install a grease trap or interceptor that meets Eugene Municipal Code § 5.230 and the manufacturer’s specifications for your projected flow rate and grease waste. The device must be accessible for cleaning and inspection, typically requiring a licensed plumber’s sign-off. Failure to match the device capacity to your facility's type and size (e.g., a 2,000-gpm interceptor for a full-service kitchen) will fail inspection and require costly replacement. Duration: 1–2 weeks for contractor scheduling and installation.
Install and maintain control access hole for observation and sampling
Provide a secure, unlocked, and clearly marked access point (manhole or sampling port) on the discharge line downstream of the interceptor, as specified in the City's pretreatment manual. The access must be at ground level, free of obstructions, and allow city inspectors to safely collect a wastewater sample. Missing or obstructed access ports result in immediate inspection failure and a re-inspection fee. Duration: 1–3 days for a plumbing contractor to install.

See All RequirementsProcessing times vary and depend heavily on plan review complexity and inspection scheduling with the Eugene Public Works Department. For new construction or major kitchen remodels requiring a Building Permit, expect the grease trap permit review to be part of that longer timeline. Contact the Public Works Development Services counter to confirm current wait times for your specific project type.
The City of Eugene's official government filing fee for the grease trap/interceptor permit application is $0. However, this fee is typically assessed as part of a larger plumbing or building permit package; you may incur fees for the related plan review and inspections. Always verify the complete fee structure for your project with the Public Works Department, as costs for required companion permits like the Certificate of Occupancy are separate.
No, grease trap permits are site-specific and tied to the approved plumbing system at your original address. You must apply for a new permit at the new location, as the design and sizing requirements are based on that specific kitchen's layout and fixture count. The application process must be completed before operating the food service equipment at the new site, per Eugene Public Works regulations.
The installation permit itself does not require renewal, but ongoing compliance is enforced through annual inspections and maintenance reporting. The Public Works Department or Lane County Public Health typically mandates that grease interceptors be pumped and inspected by a licensed waste hauler at least every 90 days for most restaurants. You must keep these service records on-site for verification during routine inspections.
A city inspector verifies the installation matches the approved plans, checking for proper sizing, venting, accessibility, and that all connections to kitchen fixtures are correct. For final approval, you may need to provide a certification from the installer and demonstrate that the trap is empty, clean, and fully operational. Passing this inspection is often a prerequisite for receiving a final Building Permit approval or scheduling your health department opening inspection.
