Understanding Local FOG Regulations
In National City, used cooking oil falls under the broader category of Fats, Oils, and Grease (FOG). The city's FOG Control Program establishes strict rules to prevent these substances from entering the sanitary sewer system, where they can cause costly blockages and overflows 1.
Key legal requirements include:
- Prohibition of Improper Disposal: It is illegal to pour used fryer oil, grease, or food scraps down sinks, floor drains, or into storm drains 1 2.
- Mandatory Licensed Haulers: Businesses must contract with a licensed waste grease hauler or recycler for collection. Using unlicensed operators for grease trap or UCO collection can result in violations 1.
- Grease Interceptor Maintenance: Grease traps and interceptors must be regularly pumped and maintained by a professional service, typically when they are 25% full of grease and solids, to prevent FOG from escaping into sewer lines 3 4.
Non-compliance can lead to enforcement actions, including fines and mandatory corrective measures. The City of National City provides resources and program details through its Engineering and Public Works department 1.
Best Practices for On-Site Storage and Handling
Proper storage before pickup is crucial for safety, compliance, and maintaining the quality of the oil for recycling.
Container and Location Guidelines:
- Use dedicated, sealed containers such as barrels or collection tanks provided by your hauler. These should be made of non-reactive materials like stainless steel or heavy-duty plastic 2 4.
- Store containers in a cool, dark, and secure area to prevent degradation and avoid attracting pests.
- Clearly label containers with the contents (e.g., "Used Vegetable Oil") and the accumulation start date.
- Ensure storage areas are accessible for hauler trucks during scheduled pickup times.
Preventing Contamination: The value of UCO for recyclers depends on its purity. To avoid surcharges and ensure efficient recycling, keep water, food debris, chemicals, and other liquids out of the oil collection container 5. Contaminated oil is more costly to process and may incur additional fees from your collection service.
The Collection and Recycling Process
A well-managed UCO program follows a consistent cycle from your kitchen to its new life as a renewable product.
1. Accumulation & Scheduling: Oil from fryers is safely drained into on-site storage containers. Your licensed hauler will establish a regular pickup schedule-weekly, bi-weekly, or monthly-based on your volume. Many providers also offer on-call or emergency pickup services 6 7.
2. Professional Pickup: On the scheduled day, a trained technician will collect the full containers, often replacing them with clean, empty ones. They transport the oil in specialized trucks to a recycling facility 8.
3. Transformation & Reuse: At the recycling facility, the oil undergoes filtering and cleaning to remove impurities. The refined oil is then processed into renewable biofuels like biodiesel or renewable natural gas (RNG), animal feed supplements, or industrial ingredients 9 10. This process diverts waste from landfills and reduces reliance on fossil fuels.

Evaluating Service Providers and Cost Structures
Choosing the right used cooking oil collection partner involves more than just comparing prices. Service reliability, compliance expertise, and transparency are key factors.
Common Service Models and Pricing:
- Free Pickup with Revenue Share: For establishments generating high volumes (often over 100 gallons per month), some haulers may offer free collection and even share a portion of the revenue from the recycled oil 11.
- Fee-for-Service: This is common for small to mid-volume generators. Costs can include a monthly service fee (ranging from approximately $35 to $120+) or a per-pickup charge (which may range from $75 to $250+), depending on frequency and volume 12 5.
- Additional Potential Fees: Be aware of potential surcharges for contaminated oil, emergency or after-hours service, or locations that are difficult to access 12 13.
Questions to Ask Potential Providers:
- Are you licensed to operate as a grease hauler in National City and San Diego County?
- What is included in the standard service (e.g., container provision, spill cleanup)?
- How do you handle scheduling and communication for pickups?
- Can you provide documentation for compliance reporting?
- What is your process if my oil is accidentally contaminated?
Benefits Beyond Compliance

Resource Conservation: Turning a waste product into a valuable resource supports local green industries and contributes to regional sustainability goals 9.
Getting Started and Maintaining Compliance
To establish or audit your current UCO collection system:
- Assess Your Volume: Track how much oil you use and dispose of weekly to accurately communicate your needs to service providers.
- Verify Hauler Licenses: Confirm that any hauler you consider is properly licensed. Resources like the California FOG database can assist in this search 2.
- Review Your Contract: Understand the terms, including service frequency, fee structure, and responsibilities for containers and spills.
- Train Your Staff: Ensure all kitchen employees understand proper oil disposal procedures to prevent drain clogs and container contamination.
- Keep Records: Maintain logs of oil collection dates, hauler receipts, and grease interceptor maintenance reports. This documentation is vital for demonstrating compliance during inspections 1.
