Alberta Environment and Parks has completed the 2011-2013 Canadian Ambient Air Quality Standards (CAAQS) PM2.5 and ozone assessment. This report is the first such annual assessment applying the new CAAQS standards and approach. Alberta’s six air zones have been assessed for achievement against the CAAQS using thirty three ambient air monitoring stations distributed throughout the province. A summary of the CAAQS achievement status and the air management level for each air zone is presented in Table 1. Management actions have already been initiated within some air zones as part of Alberta’s implementation of the former Canada-wide standards for PM2.5 and ozone.
