California has some of the most rigorous air quality regulations in the United States. Industries that emit regulated air pollutants are expected to continuously monitor emissions, verify monitoring accuracy, and maintain complete compliance records. This is why Continuous Emissions Monitoring Systems (CEMS), Cylinder Gas Audits (CGA), Relative Accuracy Test Audits (RATA), and Certification Services are essential for many industrial facilities operating in the state.
For facilities such as refineries, power plants, cement manufacturers, chemical processing facilities, waste-to-energy plants, and other regulated industries, these services are not just best practices—they are often required under operating permits and environmental regulations.
At Energy Environmental Solutions, Inc. (EES), we help industries meet these requirements with reliable testing, expert support, and accurate reporting.
Why Are CEMS, CGA, RATA & Certification Important?
Environmental agencies require facilities to demonstrate that emissions monitoring systems produce accurate, reliable, and traceable data. Continuous monitoring helps verify compliance with permit limits while supporting cleaner air and environmental protection.
These services help facilities:
Demonstrate compliance with environmental permits
Verify emissions monitoring system accuracy
Maintain reliable emissions records
Support regulatory inspections and audits
Reduce the risk of non-compliance
Improve confidence in reported emissions data
Reliable monitoring also enables facilities to identify operational issues early and make informed decisions before they become larger compliance problems.
What Is CEMS?
A Continuous Emissions Monitoring System (CEMS) continuously measures pollutants released from industrial processes and records emissions data for compliance reporting.
Facilities often use CEMS to monitor pollutants such as:
Nitrogen Oxides (NOx)
Sulfur Dioxide (SO₂)
Carbon Monoxide (CO)
Carbon Dioxide (CO₂)
Oxygen (O₂)
Opacity and other regulated parameters (depending on permit requirements)
CEMS provides continuous operational data that supports environmental reporting and regulatory compliance.
What Is RATA?
A Relative Accuracy Test Audit (RATA) evaluates the accuracy of a facility’s CEMS by comparing it with a certified reference test method.
Facilities remain compliant with applicable permit conditions
Routine RATA testing is an important part of maintaining confidence in emissions monitoring systems.
What Is CGA?
A Cylinder Gas Audit (CGA) evaluates analyzer performance using certified calibration gases.
CGA helps verify:
Analyzer calibration accuracy
Instrument performance
System precision
Long-term monitoring reliability
Regular audits help ensure that emissions monitoring equipment continues to perform as intended.
Why Is Certification Necessary?
Certification demonstrates that a monitoring system has been properly evaluated and is operating according to applicable performance requirements.
Certification and recertification may be required after:
Installation of a new monitoring system
Major equipment modifications
Repairs affecting system performance
Regulatory or permit requirements
Maintaining current certifications supports continuous compliance and helps prepare facilities for inspections.
Risks of Delaying Compliance
Waiting until an inspection or regulatory review to address monitoring requirements can create unnecessary challenges, including:
Delays in regulatory approvals
Increased corrective maintenance
Permit compliance issues
Operational disruptions
Additional testing requirements
Increased project costs
A proactive compliance strategy helps facilities avoid these situations while maintaining confidence in their emissions monitoring programs.
