Continuous Emissions Monitoring

Mandatory reporting of continuous emission monitoring data came into being in Alberta with the April 2007 release of Part I of the 2006 Amendments to the Air Monitoring Directive, 1989.

The Continuous Emission Monitoring System (CEMS) Code establishes requirements for the installation, operation, maintenance and certification of continuous emission monitoring systems. These requirements will ensure effective measurement, recording and standardized reporting of specified emissions and other parameters.

In addition, the code establishes requirements for alternative monitoring systems and for the quality assurance and quality control of continuous emission monitoring data.

Monitoring operators can now submit required monitoring information electronically.
