Mandatory electronic reporting of continuous emission monitoring data began in Alberta with the April 2007 release of the 2006 Amendments to the Air Monitoring Directive, 1989. The 1989 Air Monitoring Directive (AMD) has now been amended and
replaced by the 2016 AMD. Reporting of continuous emission monitoring data is required by Chapter 9 of the 2016 AMD.
The Continuous Emission Monitoring System (CEMS) Code was published in 1998. The 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.
