DSBRT - PIC 3 - Air Quality

Data from air quality monitoring stations was examined to determine existing conditions and the location of sensitive receptors. The existing conditions review is underway.

Air emissions that will be assessed include: CO, NO2, SO2, VOCs, PM2.5, PAH, GHG

Examples of sensitive receptors include:

  • Place of residence
  • Child care facility
  • Health care facility
  • Senior citizen’s residence
  • Long-term care
  • School

Next, modelling will be conducted to determine air quality levels at sensitive receptor locations. Future ‘with BRT’ and ‘without BRT’ scenarios will be modelled.


Potential construction impacts include:

  • Air pollution and dust from construction activities


To mitigate construction impacts, the following measures are proposed:

  • Cover sources of dust where possible
  • Apply dust suppressants
  • Use low emissions equipment where possible
  • Limit dust generating activities during high-wind conditions

Operational impacts and mitigation measures will be presented at Public Information Centre #4.
