The Clean Air Act states acidic deposition (acid rain) is believed to cause long-term and long-range detrimental impacts. The first effects appear on trees and in lakes. The gradual rise in worldwide temperatures, called global warming, is believed to be caused by increasing carbon dioxide emissions from fossil fuel combustion. These reasons require fossil fuel plants to have a certified, operational Continuous Emissions Monitoring System (CEMS) in place.

The Calibration of CEMS Components training course describes how system components are calibrated to maintain accurate emissions records. This online course discusses:

• Stack flowmeter calibration
• Nitrogen oxide, sulfur dioxide, and carbon dioxide analyzer calibration
• Opacity monitor calibration

This course is part of the Fundamental Aspects of Emission Controls training series.
