Cooking Oil Disposal: One Legal Path, and Three Ways Kitchens Get It Wrong

There is one lawful path. A transporter registered with the California Department of Food and Agriculture collects the oil from your kitchen and delivers it to a licensed receiving facility, and a manifest is created at the moment of collection. CCR Title 3 Section 1180.20 (3 CCR §1180.20) states that no vehicle may transport inedible kitchen grease unless the owner or company in control of the vehicle is registered with the Department, and CDFA states plainly that it is unlawful for any person to engage in the transportation of IKG without being registered (CDFA's rendering FAQ). Everything else, the drain, the dumpster, the guy with a truck and no decal, sits outside that path. Our service runs the compliant version for free, drops a locked container, and files your manifest automatically.

No, and a grease interceptor does not change the answer. Federal pretreatment rules prohibit discharging solid or viscous pollutants in amounts that will cause obstruction to the flow in a treatment works (the EPA's pretreatment standards). Local sanitation agencies enforce that through their own grease programs, which is why Orange County food service establishments operate under FOG Ordinance OCSD-25 and a wastewater discharge permit (OC San's business FOG program), and why the City of San Diego runs its Food Establishment Wastewater Discharge program (San Diego's FEWD program). Bulk oil belongs in a collection container that a registered transporter empties, not in the plumbing.

No. Liquid waste does not belong in a solid waste container, and no municipal trash hauler is permitted to receive used fryer oil from a commercial kitchen. Containers crack under compaction, the oil ends up on the pad and in the storm drain, and the cleanup lands on the property. There is also no small-quantity exception for a food business: a few gallons a week follows the same path as a few hundred. If you are generating oil, you need a container and a registered transporter, even at low volume.

Two checks take about a minute. First, look at the truck. Under CCR Title 3 Section 1180.20 (3 CCR §1180.20) each registered vehicle carries an individually numbered decal for the current calendar year on the windshield or trailer, plus signs on both front doors with the business name, address or carrier ID number, and license plate information. Second, look the company up. CDFA publishes lists of registered inedible kitchen grease commercial transporters, renderers, and collection centers (CDFA's licensed transporter registry). If a company is not on the list and the truck has no decal, no manifest it produces will hold up.

Cooking oil disposal is the legal act: moving the oil out of your kitchen through an approved channel with documentation to prove it. Recycling is what happens to the material afterward, which for used fryer oil means it becomes feedstock for biodiesel and renewable diesel instead of going to landfill. Rendering is the licensed facility class that receives the load and does the processing. The three overlap by design here, because the only approved destination for collected oil is a permitted processor. CDFA regulates 47 renderers statewide, 21 traditional and 26 that handle inedible kitchen grease only (CDFA's rendering FAQ).

The two-year minimum in CCR Title 3 Section 1180.24 (3 CCR §1180.24) applies to the transporter copy and the receiving facility copy of every manifest. Your copy, Part 1, must be given to you at the time of collection or delivered within 45 calendar days. Because the retention duty sits on the hauler rather than on you, operators who have changed vendors a few times often cannot reconstruct their own history. We hold your records for two years, and keep them searchable so a date-range export takes seconds.

Enforcement is local and it escalates. The City of San Diego, for example, investigates food facilities after grease-related sewer blockages and can impose additional requirements on the establishments it identifies as contributors; non-compliance draws a notice of violation with an administrative fee and can lead to permit revocation and termination of sewer service (San Diego's FEWD program). Losing sewer service closes a kitchen. The subtler cost is that you remain the generator of record. If the oil that left your lot never reached a licensed facility, the trail still starts at your address.

Because collected fryer oil has commodity value as renewable fuel feedstock, and we are paid on that side of the transaction rather than by your kitchen. You get scheduled pickups, a free locked container, container servicing, and a manifest after every collection at no cost, with no contract and no minimum term. High-volume kitchens can also qualify for a rebate on the oil itself. Call and a real person picks up, day or night; we call back the same business day and typically run a first pickup within 3 to 5 business days.
