CAIR Reduces Iowa’s Emissions
- By 2015, CAIR will help Iowa sources reduce emissions
of sulfur dioxide (SO2) by 7,000 tons or 5 percent.

CAIR Helps Iowa and its Neighbors
- Because air emissions travel across state boundaries,
reducing the emissions from sources in Indiana also will reduce
fine particle pollution and ground-level ozone pollution in other
areas of the country.
- Currently, Iowa sources significantly contribute to fine
particle pollution in 2 other states:
Illinois & Indiana
- Currently, Iowa sources also significantly contribute
to ground-level ozone pollution in:
Wisconsin
CAIR Makes Iowa’s Air Cleaner
- CAIR helps Iowa meet and maintain the National Ambient
Air Quality Standards (NAAQS) for ground-level ozone and fine particle
pollution.
- SO2 and NOx contribute to the formation of fine particles (PM),
and NOx contributes to the formation of ground-level ozone.
- Areas meeting the NAAQS are in attainment. Those areas not meeting
the standards are known as “nonattainment areas.”
Fine Particle Pollution
- At the end of 2004, no Iowa counties were designated nonattainment
for EPA’s health-based standards for fine particle pollution.
Ground-level Ozone
- At the end of 2004, no Iowa counties were designated nonattainment
for EPA’s health-based standards for ground-level ozone pollution.
CAIR is Smart for Iowa’s Economy
- CAIR helps maintain coal as a viable fuel/energy source.
- Regional electricity prices are not significantly impacted by CAIR,
and are projected to be below 2000 levels.

Notes:
1) Partial counties are identified by (P) following the county
name.
2) Projections concerning future levels of air pollution in specific
geographic locations were estimated using the best scientific models
available. They are estimations, however, and should be characterized
as such in any description. Actual results may vary significantly
if any of the factors that influence air quality differ from the
assumed values used in the projections shown here.
3) Small emission increases can occur in a state under CAIR where
shifts in power generation occur, but overall improvements occur
throughout the CAIR region. The Final CAIR includes a compliance
supplement pool of NOx allowances (roughly 200,000 allowances)
for the annual program, which could lead to slightly higher annual
NOx emissions than are stated here.
4) The data presented here is based on recently completed, revised
Integrated Planning Modeling (IPM), reflecting CAIR as finalized. This recent data may
differ slightly from modeling results in the Final CAIR Federal
Register Notice and Regulatory Impact Analysis (RIA) which were based on modeling that was completed
before EPA had determined the final scope of CAIR. The primary
difference in the earlier modeling included AR, DE, and NJ in the
annual SO2/NOx requirements, and did not include an ozone season
cap on any states.
5) Emissions reductions take into account state and federal pollution
control programs in place when EPA last updated its models in mid-2004.
Reductions from more recent state programs or settlement actions
are not reflected in these tables.
6) Retail electricity prices are by North American Electric Reliability Corporation (NERC) region.
