Multi-Sector Air Pollutant Regulations Compliance

The Multi-Sector Air Pollutants Regulations (MSAPR) were released on May 27, 2017 under the Canadian Environmental Protection Act, 1999. The MSAPR require owners and operators of specific industrial facilities and equipment types to meet consistent performance standards across the country. The objectives of this regulations as it relates to the oil and gas industry are to:

  • Limit the amount of nitrogen oxides (NOx) emitted from modern (new) and pre-existing (existing), gaseous-fuel-fired non-utility boilers and heaters used in many industrial facilities

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

Key dates to note in the regulations are the 1st phase of NOx limits for pre-existing engines must be achieved by January 1, 2021, and the 2nd phase of NOx limits for pre-existing engines must be achieved by January 1, 2026.

Due to the complexity of this regulation, Envirotech offers its services as regulatory air emissions experts to develop a Project Management Plan for your company to ensure that you minimize costs in achieving compliance, and minimize downtime in operations.

The key components of the Project Management Plan include:

  • Assist client in developing a business case including scope, objectives, deliverables, and stakeholders of a project.
  • Analyze client engine fleet NOx emissions based on prescribed default emission factors.
  • Develop engine performance check plan.
  • Develop a capital plan that outlines potential engine retrofit or replacement options and estimates capital costs to ensure January 2021 and 2026 compliance targets are met.
  • Develop a preliminary implementation plan based on most economic timeframes for engine retrofits/upgrades, minimizing engine downtime and other associated costs.
  • Prepare field surveys to capture all engine data required to completed engine registration.
  • Determine optimal engine grouping method for registration (flat limit or yearly average approach).
  • Complete engine registration for all pre-existing engines >250 kW in Environment Canada’s SWIM system.
