Thermal Oxidizer Testing in California (2026): Latest Updates, Pros, Cons & How EES Helps Industries Stay Compliant
California continues to maintain some of the nation’s most demanding requirements for controlling VOC and toxic air contaminant emissions from industrial operations. For facilities using thermal oxidizers, regenerative thermal oxidizers (RTOs), catalytic oxidizers, afterburners, or related combustion-control equipment, performance testing can be an important part of demonstrating that the control device is actually achieving the required emissions-control performance.
A key 2026 development is that South Coast AQMD is actively evaluating control technologies and emissions requirements across several industrial sectors. Its March 2026 staff report for aerospace coating operations, for example, discusses thermal oxidizers as VOC and toxic-air-contaminant controls and notes that they can achieve destruction efficiencies above 98% in appropriate applications. At the same time, the report highlights an important challenge: thermal oxidation of certain compounds can create secondary pollutants such as HCl and HF, potentially requiring additional control equipment.
For industrial facilities, this means thermal oxidizer testing should not be viewed simply as a one-time emissions test. Temperature, residence time, combustion conditions, VOC destruction efficiency, NOx, CO, and potentially other pollutants all need to be considered according to the applicable permit and Air District requirements.
Energy Environmental Solutions, Inc. (EES) helps California industries with Thermal Oxidizer Testing, VOC Testing, Source & Stack Testing, NOx and CO Testing, Compliance Test Protocol Development, CEMS/RATA/CGA, Engineering Studies, and Regulatory Reporting.
What Is Thermal Oxidizer Testing?
A thermal oxidizer destroys VOCs and other combustible pollutants by oxidizing them at elevated temperatures.
Testing can be used to determine whether the equipment is achieving the required destruction or removal efficiency (DRE) and whether emissions from the control device comply with applicable permit or regulatory limits.
Depending on the facility and permit, testing may evaluate:
VOC destruction efficiency
VOC concentration
NOx emissions
CO emissions
CO₂
O₂
Flow rate
Temperature
Residence time
Combustion conditions
Particulate matter
Toxic air contaminants, where applicable
The exact testing requirements are facility- and permit-specific. There is no single California-wide thermal-oxidizer test that automatically applies to every facility.
Latest California Thermal Oxidizer Updates for 2026
1. South Coast AQMD Is Actively Evaluating Thermal Oxidizers
One of the clearest 2026 regulatory developments comes from South Coast AQMD’s work on Proposed Amended Rule 1124, covering aerospace assembly and component manufacturing operations.
The March 2026 staff report evaluates thermal oxidizers as a potential control technology for VOC and toxic-air-contaminant emissions. South Coast AQMD states that thermal oxidizers can achieve destruction efficiencies exceeding 98% under suitable operating conditions.
However, the agency also identifies limitations for some compounds. For example, thermal oxidation of chlorinated and fluorinated compounds can generate acidic byproducts such as hydrochloric acid and hydrofluoric acid, potentially requiring scrubbers and additional controls.
What this means for industry: choosing a thermal oxidizer is not simply about achieving a high VOC destruction percentage. Facilities must also evaluate the pollutants created by the combustion process.
2. 2026 Rulemaking Continues Across California’s Industrial Air Sector
South Coast AQMD’s 2026 regulatory agenda includes numerous proposed amendments and new rules addressing particulate matter, toxic air contaminants, monitoring, New Source Review, and other air-quality requirements.
This broader regulatory activity matters to facilities operating thermal oxidizers because a control device may address one pollutant while creating or affecting another.
For example, South Coast AQMD’s emissions-reporting guidance for thermal oxidation notes that when VOC vapors are destroyed through thermal oxidation, NOx, SOx, CO, PM, and toxic air contaminants may also be generated. The agency encourages operators to use site-specific test results where available for emissions calculations.
That makes comprehensive testing increasingly valuable.
3. Source Testing Can Be a Permit Requirement
Thermal oxidizer testing requirements are often written directly into individual facility permits.
For example, a Bay Area Air Quality Management District permit requires a thermal oxidizer to be source tested annually for VOC control efficiency as well as NOx and CO emissions, with results reported to the District. The permit also specifies continuous temperature monitoring and recordkeeping requirements.
This demonstrates an important point:
Thermal oxidizer testing frequency and pollutants are determined by the applicable permit and regulatory requirements.
Some facilities may require annual testing; others may have different schedules or testing triggers.
4. California Facilities Continue Using Performance Testing to Demonstrate Control Efficiency
South Coast AQMD Hearing Board documents also show real-world applications of thermal oxidizers.
In a 2025 case involving a petroleum facility, a portable thermal oxidizer was allowed temporarily to replace an afterburner, subject to conditions including a minimum overall VOC control efficiency of 99% and a performance test shortly after startup to demonstrate compliance.
Although that order was issued in 2025, it remains a useful example of how regulators can use performance testing to verify control-device performance during temporary or modified operating conditions.
Why Is Thermal Oxidizer Testing Important?
A thermal oxidizer may look like a simple solution:
VOC-containing gas → high-temperature combustion → cleaner exhaust
But real-world performance depends on several variables.
If the temperature is too low, residence time is inadequate, mixing is poor, or the system is overloaded, destruction efficiency can decline.
Testing helps answer the critical question:
Is the thermal oxidizer actually performing as required under real operating conditions?
Key Parameters That Can Affect Performance
Temperature
Thermal oxidation requires sufficient temperature to initiate and maintain the oxidation reaction.
Temperature requirements vary depending on the equipment, pollutants, permit, and process.
Residence Time
The contaminated gas needs enough time inside the combustion chamber for the oxidation reaction to occur effectively.
Turbulence & Mixing
Good mixing of combustion air and contaminated gas is essential for consistent oxidation.
South Coast AQMD specifically identifies temperature, residence time, and turbulence/mixing as important design factors for thermal oxidizers.
VOC Loading
An oxidizer operating with a highly variable VOC concentration may behave differently from one receiving a stable waste stream.
Testing under representative operating conditions is therefore critical.
Pros of Thermal Oxidizer Testing
1. Demonstrates Compliance
Testing can provide documented evidence that the control device is meeting applicable permit requirements.
2. Verifies VOC Destruction Efficiency
Testing can determine whether the thermal oxidizer is achieving its required VOC control efficiency.
3. Identifies Performance Problems
Testing can reveal declining control efficiency, combustion problems, unusual emissions, or operational conditions requiring investigation.
4. Supports Permit Compliance
Reliable source-test results can support permit renewals, modifications, inspections, and regulatory reporting.
5. Improves Environmental Performance
Properly operated thermal oxidizers can substantially reduce VOC emissions and associated air-quality impacts.
6. Provides Better Emissions Data
Site-specific testing can provide more defensible information than relying exclusively on generic emission factors.
Cons & Challenges of Thermal Oxidizer Testing
Thermal oxidizer testing also comes with challenges.
Testing Costs
Professional source testing requires specialized equipment, trained personnel, laboratory analysis where applicable, and technical reporting.
Production Scheduling
Testing may need to be performed during specific operating conditions, making coordination with production important.
Complex Testing Requirements
VOC destruction efficiency testing can require simultaneous inlet and outlet measurements, operating-condition documentation, and carefully designed sampling procedures.
Secondary Pollutants
Thermal oxidation can produce NOx, CO, SOx, PM, and potentially toxic or acidic combustion byproducts, depending on the waste stream. South Coast AQMD specifically highlights these considerations in its emissions-reporting guidance.
Equipment Maintenance
Burners, combustion chambers, temperature sensors, controls, fans, dampers, and related equipment need appropriate maintenance to maintain performance.
Regulatory Changes
California’s air-quality regulations continue evolving, making it important for facilities to verify current requirements rather than relying on an old test protocol.
Thermal Oxidizer Testing: What May Be Tested?
A facility’s testing program may include:
Parameter
Why It May Be Tested
VOC

Air Emissions Testing in California (2026): Latest Updates, Pros, Cons & How EES Helps Industries Stay Compliant
California continues to operate one of the most comprehensive air-quality regulatory systems in the United States. In 2026, air emissions testing, source testing, stack testing, emissions monitoring, QA/QC, and compliance reporting remain important tools for industrial facilities demonstrating compliance with air permits and applicable state, federal, and local requirements.
The regulatory environment is also evolving. South Coast AQMD’s 2026 rulemaking calendar includes more than two dozen planned rule amendments and adoptions addressing particulate matter, toxic air contaminants, monitoring, New Source Review, and other air-quality objectives. At the same time, CARB continues updating statewide programs and test methods, while EPA’s current implementation framework continues to rely on emissions inventories, monitoring, modeling, and control strategies to demonstrate progress toward federal air-quality standards.
For industrial operators, this means one thing: accurate emissions data and defensible testing are becoming increasingly important.
Energy Environmental Solutions, Inc. (EES) helps facilities manage this process through professional Air Emissions Testing, Source & Stack Testing, Compliance Test Protocol Development, CEMS Certification, RATA, CGA, QA/QC, Engineering Studies, and Regulatory Reporting.
Emissions Testing
What Is Air Emissions Testing?
Air emissions testing is the measurement and evaluation of pollutants released from industrial processes, combustion equipment, stacks, vents, and other emission sources.
Depending on the facility and permit requirements, testing may address pollutants such as:
NOx – Nitrogen Oxides
SOx – Sulfur Oxides
CO – Carbon Monoxide
VOC – Volatile Organic Compounds
PM – Particulate Matter
PM10
PM2.5
Hazardous Air Pollutants (HAPs)
Air toxics
Metals
Hexavalent chromium
Dioxins and furans
Ammonia
Greenhouse gases
California’s stationary-source testing framework can involve CARB, EPA, and local Air District test methods, with requirements varying according to the applicable agency and regulation. CARB specifically notes that compliance testing requirements can include published CARB, EPA, or other approved test methods.
Why Is Air Emissions Testing Important in California?
California’s air-quality programs are built around controlling emissions from both mobile and stationary sources. CARB identifies stationary point sources such as power plants, oil refineries, manufacturing facilities, and food-processing plants as important categories of permitted emission sources.
For facilities subject to permits, testing provides regulators and operators with information about the actual performance of emission sources. It can also support permit demonstrations, compliance determinations, emissions inventories, engineering evaluations, and corrective actions.
South Coast AQMD’s Annual Emissions Reporting program illustrates the importance of accurate emissions information: facilities meeting specified reporting thresholds must submit annual emissions reports, and the information is used to support air-quality planning and evaluation of clean-air strategies.
Latest California Air Emissions Updates for 2026
1. California’s Regulatory Activity Remains High
South Coast AQMD announced a 2026 rule calendar containing more than two dozen planned rule amendments and adoptions. The planned activities include particulate-matter reductions, toxic-air-contaminant controls, New Source Review changes, and additional monitoring requirements.
This is important for industrial facilities because testing programs designed around yesterday’s requirements may not automatically address tomorrow’s requirements.
2. Particulate Matter Continues to Receive Attention
South Coast AQMD’s 2026 public-hearing schedule includes proposed amendments involving PM10 and particulate matter, including proposed amendments to Rule 1157 and other particulate-related rules.
The agency also scheduled consideration of proposed Rule 444.1 and amendments involving Visible Emissions, Particulate Matter – Concentration, and Solid Particulate Matter – Weight.
For facilities with particulate-emitting processes, these developments reinforce the value of maintaining reliable PM testing and documentation.
3. Monitoring Requirements Are Expanding
South Coast AQMD’s 2026 rule forecast includes proposals concerning fenceline monitoring for metal toxic air contaminants and monitoring/sampling for facilities identified as having significant high-risk levels for gaseous toxic air contaminants.
This reflects a broader regulatory direction toward more detailed emissions information and greater visibility into facility impacts.
4. Air-Quality Conditions Continue to Drive Regulatory Attention
South Coast AQMD’s 2026 news releases have included ozone advisories, particle-pollution advisories, wildfire-smoke advisories, and windblown-dust advisories. In July 2026, for example, the agency issued an ozone advisory associated with a heat wave.
These events don’t mean every industrial facility must automatically perform a particular emissions test. However, they demonstrate why California continues to prioritize air-quality management and emissions-control programs.
EPA’s current guidance explains that implementation of ozone and particulate-matter standards relies on programs including air-quality monitoring, modeling, emissions inventories, and emission-control strategies.
For industrial facilities, reliable source-level emissions information can therefore become an important component of the broader regulatory picture.
Pros of Professional Air Emissions Testing
1. Stronger Regulatory Compliance
Testing provides measurable evidence that an emission source is operating within applicable permit and regulatory requirements.
Rather than relying solely on assumptions or operating conditions, facilities can use documented test results to demonstrate actual performance.
2. Better Emissions Data
Properly designed testing provides traceable and technically defensible emissions data.
This can be particularly important when data is used for:
Permit compliance
Emissions inventories
Regulatory reporting
Engineering evaluations
Corrective actions
Permit renewals
3. Early Identification of Problems
Testing can reveal problems with combustion equipment, pollution-control devices, process conditions, sampling systems, or operating parameters.
Finding a problem early is generally easier than discovering it during an inspection or after a compliance issue develops.
South Coast AQMD states that its inspectors regularly inspect businesses and may issue compliance notices when additional information is required or when minor violations are identified.
4. Improved Process Performance
Emissions testing isn’t only about compliance.
Test results can also help engineers understand how equipment is performing and identify opportunities to improve combustion, pollution-control efficiency, or operating conditions.
That can potentially translate into lower emissions, better efficiency, and improved operational control.
5. Better Inspection Readiness
A facility with organized test protocols, calibration records, field data, QA/QC documentation, laboratory information, calculations, and final reports is generally better prepared when regulators request information.
Cons and Challenges of Air Emissions Testing
Professional testing has significant benefits, but industrial operators should also understand the challenges.
Testing Can Be Expensive
Specialized equipment, qualified personnel, laboratory analysis, engineering support, and reporting can increase project costs.
Production Scheduling Can Be Difficult
Some tests must occur during representative operating conditions, which means production schedules may need to be coordinated around the testing event.
Testing Can Require Specialized Expertise
Different pollutants require different sampling and analytical approaches. Selecting the wrong method or test condition can compromise the usefulness of the results.
Regulations Can Change
California’s regulatory environment is continuously evolving. South Coast AQMD’s 2026 rule calendar itself demonstrates the volume of regulatory activity underway.
Documentation Requirements Can Be Extensive
Testing is not simply about collecting a sample. Facilities may need protocols, calibration information, operating-condition records, QA/QC documentation, calculations, and regulatory reports.
The solution isn’t to avoid testing. The solution is better planning.
What Does a Typical Air Emissions Testing Program Include?
A professional program may include:
Permit and regulatory review
Test-method selection
Compliance test protocol development
Pre-test coordination
Equipment calibration
On-site source or stack testing
QA/QC verification
Laboratory analysis when applicable
Emissions calculations
Technical report preparation
