Multi Sector Air Pollutants Regulations

Under the Environmental Protection Act 1999, the Multi-Sector Air Pollutants Regulations (MSAPR), were developed to reduce industrial emissions across Canada. MSAPR was developed as part of the Base-level Industrial Emission Requirements (BLIERs). MSAPR came into force in June of 2016. It is expected to see a 99 kt reduction from boilers and heaters by 2035. 1932 kt reduction from Spark ignition engines and 5.5 kt from the cement industry. MSAPR is going to see these reductions by the gradual phasing out of less efficient equipment.

 

MSAPR is broken down into 4 parts. Part 1 addresses boilers and heaters via classifying them and setting out emission targets. Part 2 sets out the emission targets for spark ignition engines. Part 3 is focused on Cement plants and Part 4 outlines the general requirements for the testing of NOx and SOx emissions.  

 

Part 1 Boilers and Heaters

 

Any pre-existing (June 2016) boiler or heater with a capacity of 10.5 GJ/h MSAPR regulations apply.

 

Any boiler or Heater generating over 70 g NOx/GJ needs to be phased out over 20 years (2036).

 

Three classes of Boilers/Heaters

 

Class 40: Less than 70 g NOx/Gj - no specific future NOx emissions intensity limits will apply.

Class 70: greater than 70 but less than 80 g NOx/GJ - a future limit of 26 g NOx/GJ will apply starting 2036

Class 80: greater that 80 g NOx/GJ - a future limit of 26 g NOx/GJ will apply 2026

 

Classification can be done via stack testing or arbitrary election as Class 80. Classification of pre-existing boilers needs to be submitted by June 17, 2017. (If not submitted, Boiler/ Heater is considered a Class 80)

 

Can reclassify Boilers/Heaters before December 2022 via CEM test. Reclassifying as a Class 80 to a class 70 gives ten extra years to meet the 26 g NOx/GJ limit. If it becomes a Class 40 no further action is needed.

Part 2  Spark Ignition Engines

 

Applies to any pre-existing (September 2016) engines with greater than or equal to 250 kW break power and powered by fossil fuels. Part 2 also applies to “modern” spark ignition engines that are on 1 of 13 regulated facilities that are > 100kW for low use and >75 kW for regular use.

 

Regulated Facilities:

  • (a) oil and gas facilities;

  • (b) oil sands facilities;

  • (c) petroleum refineries;

  • (d) chemicals facilities;

  • (e) nitrogen-based fertilizer facilities;

  • (f) pulp and paper facilities;

  • (g) base metals facilities;

  • (h) potash facilities;

  • (i) alumina facilities and aluminum facilities;

  • (j) power plants;

  • (k) iron, steel and ilmenite facilities;

  • (l) iron ore pelletizing facilities; and

  • (m) cement manufacturing facilities.

 

As of January 1st 2021 NOx intensity of a pre-existing regular use engine 250kW is limited to 210 ppmvd15% or 4 g NOx/kWh

 

As of January 1 2021 NOx intensity of a pre-existing regular use engine 75 kW is limited to 421 ppmvd15% or 8 g NOx/kWh. January 1st 2025 the limit changes to 210 ppmvd15% or 4 g NOx/kWh
