Ozone
2019, 2020 and 2021 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.

2021 3 Year Attainment Average =		57
2022 Year-to-Date 3 Year Running Average =		58

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.

CO
1-Hour Standard (35 ppm) – The 1-hour standard comparison is based on the number of hourly values higher than 35 ppm (it is violated if exceeded more than once per year). 8-Hour Standard (9 ppm) – The 8-hour standard comparison is based on the number of 8-hour averages higher than 9 ppm (it is violated if exceeded more than once per year).
