The emissions data used in the report are measured or estimated values from EPA's National
Emissions Inventory (NEI). Starting in 1997, the NEI incorporated power industry data
measured by the Continuous Emissions Monitoring System (CEMS). For 2002, the preliminary
version of the NEI was used, which includes the 2002 CEMS data, but does not include 2002
data for other sources submitted by state, local, and tribal air agencies.
EPA used CEMS data for the power industry for 2003 and 2004. Emissions for other sources for
that period were estimated by interpolating between the 2002 preliminary NEI data and a
projected 2010 emission inventory developed to support the Clean Air Interstate Rule.

Ozone
On average, ozone has declined between 1997 and 2004. These improvements in ozone are in
response to both state and regional reductions in NOx and VOC emissions. The level of ozone
improvement varies from site to site.

Notes:
•	Data from exceptional events are not included.
•	The reader is cautioned that this summary is not adequate in itself to numerically rank MSAs
according to their air quality.
•	The monitoring data represent the quality of air in the vicinity of the monitoring site and, for some
pollutants, may not necessarily represent urban-wide air quality.
