CAIR Helps Massachusetts and its Neighbors
- Because air emissions travel across state boundaries,
reducing the emissions from sources in Massachusetts also will
reduce ground-level ozone pollution in other areas of the country.
- Massachusetts sources significantly contribute to ground-level
ozone pollution in 2 other states:
Rhode Island & New Jersey
CAIR Makes Massachusetts’ Air Cleaner
- CAIR helps Massachusetts 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 Massachusetts counties were designated
nonattainment for EPA’s health-based standards for fine
particle pollution.
Ground-level Ozone
- At the end of 2004, 14 Massachusetts counties were designated
nonattainment for EPA’s health-based standards for ground-level
ozone pollution.
- Existing Clean Air Act Programs will bring all of these counties
into attainment by 2010.

CAIR is Smart for Massachusetts’ 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 Coporation (NERC) region.
