(a) Although the modelling predictions in the table have been rounded for presentation purposes, the changes were calculated<br />
directly from model outputs. Therefore, it is feasible to show small changes without an apparent change in the listed<br />
concentrations.<br />
(b) Maximum 1-hour predictions exclude the eight highest 1-hour concentrations, as per the Alberta model guidelines<br />
(AENV 2003).<br />
(c) Developed areas include the <strong>Project</strong> Development Area and existing and approved open pit mines and upgrading complexes<br />
within the regional study area (RSA) and local study area (LSA).<br />
(d) The 1-hour, 24-hour and annual Alberta Ambient Air Quality Objectives for SO2 are 450, 150 and 30 µg/m³, respectively.<br />
(e) The number of occurrences is based on the concentrations outside of developed areas.<br />
