Why California Regulates Used Cooking Oil

California has some of the strictest environmental and waste management laws in the United States and for good reason. Every year, restaurants generate millions of gallons of used cooking oil, grease, and fats. When managed improperly, they cause:

• Blocked sewer lines

• Costly municipal cleanups

• Environmental contamination

• Increased carbon emissions

• Rodent/pest attraction

• Fire hazards in commercial kitchens

To prevent this, California enforces strict commercial waste oil laws, ensuring all restaurants handle, store, recycle, and transport cooking oil responsibly.

If you run a restaurant, café, food truck, bakery, or ghost kitchen, understanding these laws is not optional it’s a legal obligation.

Failure to comply can result in:

• Fines

• Inspections

• Business closures

• Legal action from city or county authorities

This is why every food business owner should understand how used oil regulations work and how to meet restaurant grease trap requirements flawlessly.

Understanding Waste Oil Laws in the Food Industry

California classifies used cooking oil as a regulated waste material, meaning it must be handled with the same care as industrial waste. Under the state’s Waste Oil Laws, restaurants must:

• Store used oil in approved containers

• Keep containers sealed and labeled

• Prevent spills at all times

• Work only with licensed oil collection companies

• Maintain disposal receipts and manifests

• Comply with local health, fire, and environmental departments

These rules exist to protect public health, sewer systems, and the environment.

Even a single gallon of improperly disposed oil can:

• Destroy wastewater pipelines

• Pollute ocean water

• Kill plants and wildlife

• Trigger costly sanitation repairs

California does not take these risks lightly and neither should restaurants.

Restaurant Grease Trap Requirements: What You Must Know

Grease traps (also known as grease interceptors) are mandatory for most food service businesses in California. They prevent fats, oils, and grease (FOG) from entering the sewer system.

Under restaurant grease trap requirements, you must:

1. Install an Approved Grease Trap or Interceptor

Units vary based on:

• Kitchen size

• Volume of cooking

• City/County rules

• Type of food prepared

Most restaurants are required to install a large outdoor interceptor.

2. Clean the Trap Regularly

California laws typically demand cleaning when:

• The trap is 25% full
  or

• Every 30–90 days (depending on local rules)

3. Maintain Proper Records

You must keep:

• Cleaning logs

• Pumping records

• Inspection forms

4. Work With a Licensed Grease Removal Company

DIY cleaning is illegal for commercial facilities.

5. Keep Traps Accessible for Inspectors

Health department officials can conduct inspections without notice.

If you operate a restaurant, these requirements are not suggestions they are legally enforceable.

The Risk of Non-Compliance for Restaurants

Failing to comply with grease trap laws or waste oil laws can lead to severe consequences including:

• Health department violations

• Heavy fines (up to thousands of dollars)

• Suspension of operations

• Mandatory system upgrades

• Lawsuits for environmental damage

• Sewer overflow liability charges

Ignoring grease trap rules can easily cost more than following them.

How Grease Traps Actually Work (Beginner-Friendly Explanation)

Many restaurant owners and staff follow the rules but don’t fully understand how a grease trap functions. Here’s a simple breakdown:

1. Kitchen wastewater enters the trap

2. Fats, oils & grease float to the top

3. Food solids sink to the bottom

4. Clean(er) water exits into the sewer

5. Grease and solids stay trapped inside

But…

When the trap becomes too full, grease slips through and enters city sewer lines. This creates FOG blockages, and California will hold restaurants responsible.

This is why proper maintenance is crucial not optional.

California Used Cooking Oil Regulations Explained

California’s used cooking oil rules come from:

• California Environmental Protection Agency (CalEPA)

• Department of Toxic Substances Control (DTSC)

• County Environmental Health Departments

• State Water Resources Control Board

• Local wastewater districts

Key regulations include:

✔ Used Oil Must Be Stored in Approved Containers

Leak-proof, labeled, sealed.

✔ Containers Should Be Kept Away From Drains

Spill prevention is mandatory.

✔ Transportation of Used Cooking oil by Only Licensed Collectors.

Transporting oil without proper permits is a crime.

✔ Restaurants Must Maintain Disposal Manifests

Collectors must provide documentation proving your oil was recycled legally.

✔ Oil Must NEVER Be Dumped:

• Down sinks

• Into dumpsters

• Outside

• Into storm drains

• Onto the ground

These actions violate state environmental laws, punishable by large fines.

Record-Keeping Rules & Compliance Documentation

California requires restaurants to maintain:

• Pickup receipts

• Grease trap service records

• Waste oil recycling manifests

• Inspection logs

• Spill incident reports (if applicable)

Your documentation must be available for surprise inspections.

This recordkeeping protects your business from liability and demonstrates proper compliance.

Waste Cooking Oil Theft: A Hidden Legal Issue

Used cooking oil theft is rising across California because it can be resold for biodiesel production. But here’s what most restaurant owners don’t realize:

Oil theft is YOUR liability.

If oil is stolen:

• You cannot prove proper disposal

• You cannot maintain required manifests

• You risk failing waste oil law compliance

• You may be fined during inspections

This is why partnering with a licensed, reliable oil recycling company is essential.
