Air Emissions Monitoring for Stationary Sources

Compliance monitoring of a stationary source can be accomplished on either a continuous or an intermittent basis. Some stationary sources use a continuous emission monitoring (CEM) system which is permanently installed on a stack or process ductwork to measure the emissions of one or more pollutants. The emissions data is recorded, averaged and stored by a computer data acquisition system (DAS). Instead of, or in addition to, the CEM system measurements, a source may conduct a one-time or periodic compliance emissions test to measure the magnitude of one or more of its emissions. A test typically consists of three discrete measurement runs, each run lasting one or more hours depending on the test method and pollutant concentration(s). more …
