CEMS-CGA, RATA & Certification Services in California (2026): Latest Updates, Benefits, Challenges & How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant
California continues to enforce some of the nation’s most rigorous air quality regulations, making Continuous Emissions Monitoring Systems (CEMS) a critical compliance tool for many industrial facilities. In 2026, regulatory agencies are placing even greater emphasis on Continuous Emissions Monitoring System Certification, Relative Accuracy Test Audits (RATA), Cylinder Gas Audits (CGA), Quality Assurance (QA/QC), and defensible emissions data.
Facilities operating under EPA, CARB, and local Air District permits must ensure their CEMS remain properly certified, calibrated, and maintained to produce reliable emissions data. Failure to perform required audits or certification can result in invalid monitoring data, additional regulatory scrutiny, or permit compliance issues. Recent South Coast AQMD guidance also reinforces documentation, Quality Assurance Plans (QAPs), and certification procedures for new, modified, and recertified CEMS.
At Energy Environmental Solutions, Inc. (EES), we provide complete CEMS Certification, CGA, RATA, QA/QC, and Engineering Support Services to help industries achieve accurate emissions monitoring and regulatory compliance.

Why Spike Testing for Low VOC Emissions Is Critical in California — And How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant
California continues to lead the nation in implementing stringent air quality regulations aimed at reducing Volatile Organic Compound (VOC) emissions from industrial operations. As industries adopt advanced pollution control technologies and lower emission limits, regulators increasingly require facilities to demonstrate that emissions measurement systems can accurately detect and quantify very low VOC concentrations.
Spike Testing for Low VOC Emissions plays a critical role in validating testing methods, verifying analyzer performance, and ensuring that emissions data reported to regulatory agencies is technically defensible.
At Energy Environmental Solutions, Inc. (EES), we provide professional Spike Testing for Low VOC Emissions, source testing, stack testing, engineering support, and compliance reporting to help industries meet EPA, CARB, and California Air District requirements.
What Is Spike Testing for Low VOC Emissions?
Spike Testing is a quality assurance (QA) procedure used during emissions testing to verify that analytical instruments and sampling systems can accurately measure very low concentrations of VOCs.
During spike testing, a known quantity of VOC is introduced into the sampling system to confirm that:
Sampling equipment performs correctly
VOC analyzers provide accurate measurements
Recovery efficiency meets quality standards
Measurement bias is minimized
Data quality objectives are achieved
EPA reference methods are properly implemented
Spike testing is especially important when facilities operate with highly efficient control equipment that produces extremely low VOC emissions.
Why Is Spike Testing So Important in California?
California has some of the lowest allowable VOC emission limits in the United States. As facilities achieve lower emissions through advanced control technologies, regulators expect greater confidence in measurement accuracy.
Latest Regulatory Trends & Updates
Greater Emphasis on Low-Level VOC Measurement
California Air Districts continue focusing on accurate measurement of low VOC emissions from coating operations, combustion equipment, chemical processing, refineries, and manufacturing facilities.
Improved Quality Assurance Expectations
Regulators increasingly require documented QA/QC procedures demonstrating that sampling systems and analyzers produce accurate, repeatable, and technically defensible results.
Support for Advanced Pollution Control Technologies
As industries install regenerative thermal oxidizers (RTOs), catalytic oxidizers, carbon adsorption systems, SCR units, and other advanced controls, emissions become more difficult to measure accurately without specialized testing procedures such as spike testing.
Inspection-Ready Documentation
Facilities are expected to maintain complete calibration records, spike recovery data, analyzer performance checks, and quality assurance documentation during regulatory inspections.

Why On-Site Ammonia Slip Analysis Is Critical in California — And How Energy Environmental Solutions, Inc. Helps Industries Stay Compliant
California continues to strengthen air quality regulations to reduce emissions from industrial combustion sources. As facilities increasingly rely on Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) systems to control nitrogen oxides (NOx), monitoring ammonia slip has become an essential part of maintaining environmental compliance, protecting pollution control equipment, and optimizing system performance.
For power plants, refineries, cement plants, chemical manufacturers, boilers, turbines, and other industrial facilities, On-Site Ammonia Slip Analysis helps verify that NOx reduction systems are operating efficiently without releasing excessive unreacted ammonia into the atmosphere.
At Energy Environmental Solutions, Inc. (EES), we provide professional On-Site Ammonia Slip Analysis, emissions testing, engineering support, and compliance reporting to help industries meet EPA, CARB, and California Air District requirements.
What Is On-Site Ammonia Slip Analysis?
Ammonia slip refers to unreacted ammonia (NH₃) that passes through an SCR or SNCR system and is emitted through the exhaust stack.
Excessive ammonia slip may:
Reduce catalyst efficiency
Increase particulate formation
Damage downstream equipment
Affect Continuous Emissions Monitoring Systems (CEMS)
Create visible plume concerns
Impact permit compliance
On-site ammonia slip analysis measures ammonia concentrations during normal operating conditions to optimize emissions control systems while maintaining NOx reduction efficiency.

NOx Analysis
Oxygen (O₂)
Carbon Monoxide (CO)
Stack Gas Temperature
Flow Rate Measurements
SCR/SNCR Performance Evaluation
Catalyst Performance Assessment
QA/QC Documentation
Compliance Reporting
Testing is performed using recognized EPA methodologies, approved analytical techniques, and industry best practices to provide accurate, defensible emissions data.
Why Is On-Site Ammonia Slip Analysis So Important in California?
California maintains some of the nation’s strictest air quality standards for combustion equipment. As facilities adopt advanced NOx control technologies, regulators increasingly expect facilities to optimize both NOx reduction and ammonia usage.
Latest Regulatory Trends & Updates
Continued Focus on NOx Reduction
California Air Districts continue tightening NOx emission limits for boilers, turbines, process heaters, and industrial combustion equipment. Proper ammonia slip analysis helps facilities optimize SCR/SNCR performance while maintaining compliance.
Improved Emissions Monitoring
Facilities are expected to collect accurate emissions data supported by approved EPA methods, calibration procedures, and documented QA/QC practices during source testing and compliance evaluations.
California Air District inspectors continue emphasizing complete testing records, engineering evaluations, and technical documentation during permit reviews and compliance inspections.
