Notes: Parenthetical values are approximate equivalent concentrations.
a. (a) The st<strong>and</strong>ard is attained when the expected number of days per calendar year with maximum hourly average
concentrations above 0.12 ppm is ≤ 1. (b) As of June 15, 2005, the USEPA revoked the 1-hour ozone st<strong>and</strong>ard in all areas
except the 14 8-hour ozone nonattainment Early Action Compact Areas.
b. (a) To attain this st<strong>and</strong>ard, the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations
measured at each monitor within an area over each year must not exceed 0.08 ppm. (b) The 1997 st<strong>and</strong>ard—<strong>and</strong> the
implementation rules <strong>for</strong> that st<strong>and</strong>ard—will remain in place <strong>for</strong> implementation purposes as the USEPA undertakes
rulemaking to address the transition from the 1997 ozone st<strong>and</strong>ard to the 2008 ozone st<strong>and</strong>ard.
c. Not to be exceeded more than once per year.
d. To attain this st<strong>and</strong>ard, the expected annual arithmetic mean PM10 concentration at each monitor within an area must not
exceed 50 μg/m3.
e. To attain this st<strong>and</strong>ard, the 3-year average of the 98th percentile of 24-hour concentrations at each population-oriented
monitor within an area must not exceed 35 µg/m3.
f. To attain this st<strong>and</strong>ard, the 3-year average of the annual arithmetic mean PM2.5 concentrations from single or multiple
community-oriented monitors must not exceed 15.0 µg/m3.
g. To attain this st<strong>and</strong>ard, the 3-year average of the fourth-highest daily maximum 8-hour average ozone concentrations
measured at each monitor within an area over each year must not exceed 0.075 ppm (effective May 27, 2008).
Although O 3 is considered a criteria air pollutant <strong>and</strong> is measurable in the atmosphere, it is not often
considered a regulated air pollutant when calculating emissions because O 3 is typically not emitted
directly from most emissions sources. Ozone is <strong>for</strong>med in the atmosphere by p<strong>hot</strong>ochemical reactions
involving sunlight <strong>and</strong> previously emitted pollutants or “O 3 precursors.” These O 3 precursors consist
