Frequently Asked Questions
What is stationary source emissions monitoring?
Through the Clean Air Act, the United States Environmental Protection Agency (EPA) is responsible for regulating the emissions of pollutants from stationary sources (CAA). The …
What pollutants are typically monitored by a CEMS?
CEMS are capable of monitoring the concentrations of a broad number of different pollutants; however, the precise type of contamination that must be monitored varies …
What techniques are typically used for Extractive CEMS?
The most widely used technique is Hot Extraction Method by which a wet gas sample is extracted from the stack through a sample probe and transported through a heat traced sample line to a sample conditioning system (SCS)
Why would my company need a CEMS?
Federal and State agencies have regulations in place to minimize the amount of pollution generated by industrial processes. In order to enforce these regulations, the processes must be monitored to determine how much pollution is being emitted.
Any special design consideration if flue gas has ammonia slip?
If a heater or boiler is equipped with a selective catalytic reduction unit (SCR) with ammonia injection for the NOx control, its stack flue gas will carry a residual ammonia gas (ammonia slip)
What is involved in CEMS integration?
A full CEMS integration is the specification, arrangement, and connection of all the components of a functional monitoring system.
What if CEMS fails to pass Part 75 certification requirements?
The quality assurance & quality control (QA/QC) plan as part of the rule mandated recordkeeping requirement is maintained at a regulated facility or unit to maintain a high quality, …
What are Part 75 certification requirements for CEMS?
Part 75 certification requirements establish the accuracy of CEMS. A regulated facility or unit is required to perform the initial certification tests after CEMS installation …..
What happens if pollutant emissions are over the permit limit?
Facility operators must quickly act to address emissions exceeding the limit, including shutting down the unit, if required.
How is CEMS data used?
CEMS emissions data is provided to the federal and local environmental agencies to enforce the rule mandates including the required reductions in the amount of pollutants released
What is CEMS Analytical Technology?
CEMS analytical techniques are based on the measurement of both physical and chemical properties of the parameters of interest.
