Note:
(a) The peak concentrations include the highest 1-hour predictions from the CALPUFF model.
(b) The 1-hour and 8-hour AAAQOs for CO are 15,000 and 6,000 µg/m³, respectively (AENV 2009). There is no annual AAAQO for CO.
(c) Although the modelling predictions in the above table have been rounded for presentation purposes, the changes were calculated directly from model outputs.
Therefore, it is possible to show small changes without an apparent change in the listed concentrations.
