Course overview

The Clean Air Act requires industries to use Continuous Emission Monitoring (CEM) for certain air pollution emissions. The pollutants monitored vary depending on the industry and processes taking place. The Environmental Protection Agency (EPA) has identified various industrial facilities affected by CEM requirements. This course focuses on power generation facilities, specifically fossil-fuel burning plants. The Fundamentals of Using a CEMS training course describes collecting CEMS data readings, changing calibration gas bottles, entering new data into the engineering workstations, CEM probe and sample system troubleshooting, and preventative maintenance procedures. It also explains the processes for performing weekly, monthly, quarterly, semi-annual, and annual preventive maintenance procedures. This online course is part of the Fundamental Aspects of Emission Controls training series.
