Commitments Figures 20 and 21 show Canadian NO x and VOC PEMA emission trends for 1990 through 2008. For NO x , most of the reductions come from on-road mobile sources and electric power generation, with increases in non-industrial fuel combustion and other anthropogenic sources. Similar reductions and increases were observed for VOC emissions. VOC emission reductions were primarily from on-road mobile sources, electric power generation, industrial sources and solvent utilization, with a slight increase in non-industrial fuel combustion. Reporting Air Quality for All Relevant Monitors within 500 km of the Border between Canada and the United States Both the United States and Canada have extensive networks to monitor ground-level ozone and its precursors. Both governments prepare routine reports summarizing measurement levels and trends. The latest qualityassured complete data set from both countries is for 2008. JOINT COMMITMENT Ambient Levels of Ozone in the Border Region Figure 22 illustrates ozone conditions in the border region in the metrics of national standards. The reference period is 2006 through 2008. Only data from sites within 500 km (310 miles) of the Canada– U.S. border that met data completeness requirements were used to develop this map. Figure 22 shows that higher ozone levels occur in the Great Lakes and Ohio Valley regions and along the U.S. east coast. Lowest values are generally found in the West and in Atlantic Canada. Levels are generally higher downwind of urban areas, as can be seen in the western portions of Lower Michigan, though the full detail of urban variation is not shown. For ozone, the data completeness requirement was that a site’s annual fourth-highest daily maximum 8-hour concentration (parts per billion [ppb] by volume) be based on 75% or more of all possible daily values during the EPAdesignated ozone monitoring seasons. 33
