Proposed Regulation

Multi-sector Air Pollutants Regulations

Site to be updated on June 29th, 2016

The proposed Multi-Sector Air Pollutants Regulations, (hereinafter referred to as the proposed Regulations) would require owners and operators of specific industrial facilities and equipment types to implement consistent performance standards across the country. The objectives of the proposed Regulations are to:
  • Limit the amount of nitrogen oxides (NOX) emitted from modern (new) and original (existing), gaseous-fuel-fired non-utility boilers and heaters used by industrial facilities.

  • Limit the amount of NOX emitted from modern and original stationary spark-ignition gaseous-fuel-fired engines used by industrial facilities (i.e., those used for gas compression or back-up generators).

  • Limit the amount of NOX and sulphur dioxide (SO2) emitted from cement kilns.

The proposed Regulations are part of the federal responsibility for implementing the Air Quality Management System (AQMS). The System also includes new Canadian Ambient Air Quality Standards (CAAQS), the establishment of new base-level industrial emission requirements (BLIERs) for other industries and the development of targeted air zone management plans by provinces and territories.

With respect to industrial emissions, BLIERs will be implemented in phases between 2013 and 2015 using both regulations and alternative instruments.
