EPA Performance Specification PS 3 CEMS Oxygen and Carbon Dioxide CEMS

EPA Performance Specification 3

 Master EPA Performance Specification 3 (PS-3) for Oxygen (O2) and Carbon Dioxide (CO2) Continuous Emission Monitoring Systems. This complete guide breaks down the core installation criteria, validation routines, and calculations required for stationary source compliance and industry certification preparation.

In this video, we dive deep into the precise technical specifications mandated by the US EPA:

• Calibration Drift (CD) Limits: Keeping analyzer drift within the  0.5% O2 or CO2 threshold.

• Relative Accuracy (RA) Criteria: Ensuring system accuracy meets the  20.0% standard or the absolute 1.0% alternative limit.

• Reference Method Strategies: Aligning system checks with EPA Method 3A or 3B protocols.
