District of Columbia’s Emissions
- Current emissions of SO2 and NOx are less than 1,000 tons.
CAIR Helps the District of Columbia and its Neighbors
- Because air emissions travel across state boundaries,
reducing the emissions from sources in the District of Columbia
also will reduce fine particle pollution and ground-level ozone
pollution in other areas of the country.
- Currently, District of Columbia sources significantly
contribute to fine particle pollution in 5 other states:
West Virginia, Pennsylvania, New Jersey, Delaware & New
York
- District of Columbia sources also significantly contribute
to ground-level ozone pollution in 6 other states:
Virginia, Pennsylvania, New Jersey, Connecticut, New York & Delaware
- District of Columbia’s fine particle air quality
will improve because of reductions of SO2 and NOx in:
North Carolina, Ohio, Pennsylvania, Virginia & West
Virginia
- District of Columbia ground-level ozone air quality will
improve because of reductions of NOx in:
Ohio, Pennsylvania & Virginia
CAIR Makes the District of Columbia’s Air Cleaner
- CAIR helps the District of Columbia 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, the District of Columbia was designated
nonattainment for EPA’s health-based standards for fine
particle pollution.
- CAIR will help bring the District into attainment for fine particles
by 2010.
Ground-level Ozone
- At the end of 2004, the District of Columbia was designated
nonattainment for EPA’s health-based standards for ground-level
ozone pollution.
- Existing Clean Air Act Programs will bring the District into attainment
by 2015.
CAIR is Smart for the District of Columbia’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.
