Note:
(a) Maximum 1-hour predictions exclude the eight highest 1-hour concentrations, as per the Alberta model guidelines (AENV 2003). The eight highest 1-hour predictions were not excluded from
the peak 24-hour and annual values.
(b) The 1-hour, 24-hour and annual AAAQOs for SO2 are 450, 150 and 30 µg/m³, respectively (AENV 2009).
