Revised Continuous Emission Monitoring System (CEMS) Code
On April 7, 2021, Alberta Environment and Parks (AEP) updated the Continuous Emission Monitoring System (CEMS) Code, which takes effect January 1, 2022, and will replace the 1998 code.
“Authorizations to deviate” granted under the 1998 CEMS code will not apply under the 2021 code. Licensees seeking authorization to deviate from requirements in the 2021 CEMS code should contact the appropriate AER Environmental Protection and Enhancement Act (EPEA) approval coordinator to request an authorization to deviate before the 2021 code takes effect. The only exceptions are existing authorizations to deviate under section 4 of the code, “Installation Specifications and Test Procedures.” These may remain in force until major structural modifications are made to the stack, duct, or flue.
The revised 2021 CEMS code and supplementary information are provided on the AEP CEMS webpage: https://www.alberta.ca/continuous-emissions-monitoring.aspx.
For general questions regarding the CEMS code, please contact AEP.CEMSCode@gov.ab.ca. Questions specific to AER EPEA approvals should be directed to the appropriate AER approval coordinator
