California Rule 1153.1 Compliance in 2026: Is Your Commercial Food Oven Ready for the Next NOx Requirement?
Commercial Food Oven Owners: The Zero-NOx Transition Is Getting Closer
If your facility operates commercial food ovens, bakery ovens, cooking ovens, tortilla ovens, smokehouses, roasters, dryers or other permitted commercial food-oven equipment in the South Coast AQMD jurisdiction, Rule 1153.1 – Emissions of Oxides of Nitrogen from Commercial Food Ovens deserves your attention.
South Coast AQMD adopted the current Rule 1153.1 amendment on August 4, 2023, and the rule establishes progressively tighter NOx requirements, including future zero-emission requirements for certain equipment categories.
And 2026 is an important year.
South Coast AQMD held a Rule 1153.1 Technology Check-In on February 3, 2026, followed by a Stationary Source Committee review on March 20, 2026. The District’s 2026 assessment found that zero-NOx standards remain technically feasible and cost-effective for certain smaller equipment categories, while larger units face greater cost and fuel-switching challenges.
The message for facility owners is simple:
Don’t wait until your oven is approaching a compliance trigger to start planning.
What Is California Rule 1153.1?
Rule 1153.1 controls NOx emissions from permitted commercial food ovens used to prepare food or products for making beverages for human consumption within the South Coast AQMD jurisdiction.
The regulated equipment can include:
Bakery ovens
Cooking ovens
Tortilla ovens
Drying ovens
Smokehouses
Roasters
Dryers
Other qualifying commercial food-oven equipment
The current rule establishes Phase I NOx limits, followed by future zero-emission requirements for specified categories.
What Are the Current NOx Requirements?
The 2023 amendment established Phase I limits of 30 ppm NOx for most commercial food-oven categories, while tortilla ovens heated solely by infrared burners have a 15 ppm NOx limit.
The rule then moves toward zero-emission requirements for specified equipment categories.
This is particularly important for equipment planning because a facility may need to consider:
NOx testing → equipment age → burner age → permit requirements → retrofit/replacement → electrification → future compliance
🚨 Major 2026 Rule 1153.1 Update
South Coast AQMD Completed a Technology Check-In
On February 3, 2026, South Coast AQMD held a public technology check-in for Rule 1153.1.
The purpose was to evaluate whether the technology and cost assumptions behind the future zero-NOx requirements remain appropriate.
The March 20, 2026 Stationary Source Committee materials reported an important conclusion:
Zero-NOx standards remain technically feasible and cost-effective for certain smaller units.
The District specifically reported zero-NOx standards as cost-effective for:
Bakery ovens ≤3 MMBtu/hr
Indirect-fired bakery ovens
Cooking ovens ≤3 MMBtu/hr
Smokehouses
For larger equipment, the District concluded that maintaining low-NOx requirements was appropriate because transitioning to zero emissions was not cost-effective at this time, with fuel-switching costs being a major factor.
Current status:
Staff did not recommend a rule change at the March 2026 technology check-in.
That makes the existing compliance roadmap especially important for businesses planning equipment upgrades or replacements.
What Is Coming Next?
The 2023 rule framework established future implementation dates for zero-emission requirements.
January 1, 2027
Phase II zero-emission requirements begin for applicable categories.
These include certain:
Bakery ovens ≤3 MMBtu/hr
Indirect-fired bakery ovens
Cooking ovens
Smokehouses
The specific compliance trigger for existing equipment can depend on the unit’s age and burner age, rather than simply the calendar date.
January 1, 2030
Phase III requirements apply to applicable categories under the rule framework.
The original rule development included additional time for larger equipment where zero-emission technology and electrification presented greater technical and economic challenges.
Important: Facility owners should evaluate the exact rule language, permit conditions, equipment age, burner age and applicable category before assuming a specific deadline applies to their equipment.
Why 2026 Is the Right Time to Start Planning
A major equipment transition cannot always happen overnight.
Zero-emission or electric commercial food ovens can require:
New equipment
Electrical infrastructure
Utility coordination
Facility modifications
Engineering studies
Permit review
Production planning
Installation time
Startup and compliance evaluation
South Coast AQMD has recognized that fuel-switching costs can significantly affect cost-effectiveness, especially for larger equipment.
So waiting until the last moment could create unnecessary operational pressure.
Smart approach:
Evaluate → Test → Plan → Upgrade → Verify → Comply

Need Rule 1153.1 NOx Testing or Compliance Support?
Is Your Commercial Bakery Oven Ready for California Air Quality Compliance?
If you operate a commercial bakery, food manufacturing facility, bread production plant, or other operation using regulated bakery ovens in Southern California, South Coast AQMD Rule 1153 – Commercial Bakery Ovens may affect your facility.
Rule 1153 addresses Volatile Organic Compound (VOC) emissions from commercial bakery ovens. For facilities subject to the rule, demonstrating the required level of VOC emission reduction is an important part of maintaining environmental compliance.
And there is another reason bakery operators should be paying attention in 2026:
South Coast AQMD is continuing to move commercial food-oven regulations toward lower and zero-emission technologies under Rule 1153.1.
That means bakery and food-processing facilities should not wait until the next compliance deadline, equipment replacement or regulatory inspection to evaluate their emissions and testing requirements.
What Does Rule 1153 Cover?
South Coast AQMD Rule 1153 applies to commercial bakery ovens meeting specific heat-input and VOC-emission criteria.
The rule generally applies to bakery ovens with:
Rated heat input capacity of 2 million BTU/hour or more
Average daily VOC emissions of 50 pounds or more
VOC emissions associated with fermentation and baking of yeast-leavened products
Facilities should evaluate their individual equipment, permits, operating conditions and emissions before determining applicability.
What Are the Rule 1153 VOC Requirements?
For applicable existing bakery ovens, Rule 1153 establishes VOC emission-reduction requirements based on the oven’s emissions.
Existing Bakery Ovens
Depending on the applicable emissions category:
70% minimum VOC reduction
For an existing oven with base-year average daily VOC emissions of 50 pounds or more, but less than 100 pounds.
95% minimum VOC reduction
For an existing oven with base-year average daily VOC emissions of 100 pounds or more.
New Bakery Ovens
New bakery ovens subject to Rule 1153 generally require:
95% or greater VOC emission reduction when uncontrolled average daily VOC emissions are 50 pounds or more.
These requirements can make accurate emissions measurement and control-device performance evaluation extremely important.
Why Rule 1153 Compliance Testing Matters
A bakery may believe that its oven is operating normally, but normal production does not automatically mean regulatory compliance.
VOC emissions can be influenced by factors such as:
Yeast percentage
Fermentation time
Product type
Production rate
Oven operating conditions
Exhaust flow
Control-device performance
Changes in equipment configuration
Changes in production processes
A properly planned emissions test can help establish whether the equipment is achieving the required emission-reduction performance.
For facilities subject to source-testing requirements, testing should be planned around the applicable permit conditions, regulatory requirements, approved test methods and operating conditions.

Why Does This Matter to Bakery Facilities?
Because today’s VOC compliance project can become part of tomorrow’s broader emissions-management strategy.
Bakery operators should consider both:
VOC compliance under Rule 1153
and
NOx requirements under Rule 1153.1
when planning major oven modifications, burner replacements, electrification projects, new equipment purchases or facility expansions.
What Is Coming Under Rule 1153.1?
Rule 1153.1 establishes Phase I NOx requirements and future zero-emission requirements for certain commercial food ovens.
The zero-emission provisions include categories such as:
Certain bakery ovens rated at or below 3 MMBtu/hr
Certain cooking ovens rated at or below 3 MMBtu/hr
Indirect-fired bakery ovens
