NOTES: Values above the level of
the 8-hour standard (0.075
ppm
)
are highlighted in yellow.
** Rocky Mtn. NP data through Dec.
31, 2010
The 8-hour ozone standard is
written such that attainment is met if the 3-year average of the 4th
maximum value from each of the 3 years is less than or equal to 0.075 ppm. Thus, by
looking at the 4th maximum values from the previous 2 years, it is
possible to see what the highest 4th maximum level for the current
year could be and still remain in attainment of the standard.
This table provides information on the 4th maximum values for 2008, 2009, and 2010, the current 3-year average, and the maximum possible level for 2011 in order to remain in attainment of the ozone standard. |

NOTE:
An area is considered to be in
attainment of the National Ambient Air Quality Standard when the 3-year
average of the annual 4th highest daily maximum 8-hour ozone concentration at
a site is less than or equal to 0.075 ppm. |
NOTES:
Values above the level of the 3-year average 4th-maximum 8-hour
standard are highlighted in red.
