Air Emissions
Testing
Regulatory validation and Relative Accuracy Test Audit for the Continuous Emissions Monitoring Systems (CEMS) serving Unit EUCTGHRSG2.
I. Detailed Methodology & Compliance Framework
Think of the Detailed Methodology as a high-stakes truth-test for industrial sensors. Every large energy plant has built-in monitors (Continuous Emissions Monitoring Systems) that constantly report how much pollution they are releasing—essentially an on-board computer for the smokestack.
To ensure these systems remain accurate, the law requires an independent third party to deploy laboratory-grade equipment. We compare the plant's permanent readings against our independent gold standard measurements. It is the industrial equivalent of verifying a speedometer's accuracy using a calibrated radar gun.
II. Audit Results Matrix
| Constituent | Regulatory Threshold | Audit Performance |
|---|---|---|
| Nitrogen Oxides (NOx) | ±0.015 lb/mmBtu | 0.001 lb/mmBtu |
| Carbon Monoxide (CO) | ±5.0 ppmvd @ 15% O2 | 0.29 ppmvd |
| Oxygen (O2) | 1.0% O2 Diff or 10.0% RA | 1.21% RA |
