CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines Released

     Posted by LEHDER News on

CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines On November 18, 2017, notification of the release of the CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines were posted to the Canada Gazette. This guideline was developed to support the federal, provincial and territorial air quality management system (AQMS). The AQMS includes Canadian ambient air quality standards for fine particulate matter and ground-level ozone, base level industrial emissions requirements (BLIERs) and local air zone management by the provincial/territorial jurisdictions.

This guideline introduces a NOx emission limit that is up to 50% more stringent than emission limits set out in the national emission guidelines for stationary combustion turbines published by the Canadian Council of Ministers of the Environment (CCME) in 1992 for combustion turbines commissioned after January 1, 2020. The Minister of the Environment and Climate Change recommends that the appropriate regulatory authorities adopt the guidelines as a baseline emission limit for NOx from natural gas-fuelled stationary combustion turbines.

These guidelines will provide the basis for the provinces and territories to adopt policies which incorporate these NOx emission guidelines however, the guidelines do not prevent the provinces and territories from adopting more stringent emission requirements for combustion turbines. Additionally, the Minister of the Environment and Climate Change continues to recommend those requirements of the 1992 CCME guidelines that have not been superseded by the requirements in this document.  A copy of the guideline is provided below.
