Ozone
2012, 2013, and 2014 data are needed to determine an area's attainment status with the 8-hr ozone standard. If the average is higher than 70 parts per billion, the area will not meet the ozone standard.

SO2
1-Hour Standard (75 ppb). The 1-hour standard comparison is based on the three-year average of the annual 99th percentile of the daily maximum 1-hour average concentrations. If the average is higher than 75 parts per billion, the area will not meet the SO2 standard.
