District of Columbia

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.
Average Retail Electricity Prices (AREP) in 1999 dollars 2000 2010 2015
District of Columbia’s AREP without CAIR (mills/kWh*) 80.4 59.3 69.4
District of Columbia’s AREP with CAIR (mills/kWh*) N/A 61.0 72.0
    *mill = 1/10 of a cent

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.
