Footnote 4: Rose highlighting indicates difference between 2012 Design Value and 2003‐2012 mean is greater than zero.

Footnote 2: Red highlight indicates value less than 2003‐2012 mean.

Footnote 1: Bolded numbers are outliers (two standard deviations greater than or less than the mean).

Footnote 6: Not all monitors had 10 years of data available. Some monitors appear to have been discontinued at various points,

some new monitors are added, and some monitors are missing one or more years of data.

Footnote 5: Although data is non‐normal (many areas show a generally declining trend), it falls within a relatively narrow range

with bidirectional annual fluctuations, warranting calculating a standard deviation.

Footnote 3: Green highlight indicates value greater than or equal to 2003‐2012 mean.

We refer to "unclassifiable" designations as "attainment" designations.

* The monitor that shows the Virginia Beach‐Norfolk CSA is violating the 2008 NAAQS only has data for the 2010‐12 DV. Thus, for

this area only, we include the data that EPA provides for the Norfolk‐Virginia Beach‐Newport News (HR), VA, area that is

maintenance for the 1997 NAAQS and that is entirely included within this CSA.

For purposes of this comparison only, we treat the EPA‐reported Norfolk‐

Virginia Beach‐Newport News (HR), VA, data as if it were a monitor. Thus, the

total number of monitors is 103, and 1 data point is an area that EPA supplied

DVs for because it is a maintenance area for the 1997 NAAQS.
