Learning objectives

  • Describe how to collect CEMS data readings
  • Describe basic steps required for troubleshooting probe and sample systems

  • Identify tasks to be performed weekly, monthly, quarterly, semi-annually, and annually for preventive maintenance (PM)

Course overview

In 1990, Congress passed the Clean Air Act and changed the way industries monitor and account for certain air pollutant emissions. The act requires industries to use Continuous Emission Monitoring (CEM) for these 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 (EWS)
  • CEM probe and sample system troubleshooting
  • 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.
