National Ambient Air Monitoring Standard:

Eight-hour Standard:
The three-year average of the fourth highest daily maximum eight-hour average must not be greater than 0.075 ppm (parts per million). To attain this standard, the three-year average of the fourth-highest daily maximum eight-hour average ozone concentrations measured at each monitor within an area over each year must not exceed 0.075 ppm.  (Effective May 27, 2008).

Exceedances allowed without a violation being recorded:
The term exceedance does not apply to the eight-hour standard. The three-year average is used to determine designation of attainment or non-attainment.
