What are Part 75 certification requirements for CEMS?

What are Part 75 CEMS Certification

CEMS accuracy is measured by way of Part 75 CEMS Certification. Any regulated facility is required to perform initial certification tests following CEMs installation; furthermore, ongoing certification testing is required to protect the performance of analyzers. All initial certification tests include a 7-day calibration error check, linearity check, and relative accuracy test audit.

What if CEMS doesn’t pass Part 75 Certification?

To avoid any failure issues, quality assurance and control procedures are carried out on a regular basis, and record-keeping ensures that regulation is maintained to a high standard. If CEMS fails to pass the Part 75 Certification, such as the daily calibration error check, it’s deemed out-of-control (OOC), and affected monitors are restored immediately with corrective actions.

What does CEMS integration involve?

CEMS Certification Requirements involve the integration of systems for monitoring and validation of the final point of analysis. Components are individually specified within a reliable system. Required utilities include accommodations, communications, DAS collecting, storing, and reporting. Ambient temperatures are also monitored with analyzers in controlled shelters.

Are there any special design considerations?

Heaters and boilers are sometimes equipped with a selective catalytic reduction unit (SCR) with ammonia injection in the stack flue, which can cause the flue gas to carry some residual ammonia. This issue is resolved by installing an ammonia scrubber after the probe filter to prevent ammonia slippage in the vapor phase. This is not a CEMS Certification Requirement but should be considered for units with ammonia injection capabilities.
