NOTE: This table reports the same data as in Table 4-2 aggregated by census region. Two hundred counties, for which relatively few emissions data were available, were excluded to avoid skewing the distribution in an unrealistic way.

aTotal damages (cents/MCF) are in 2007 U.S. dollars; other damages are in 2000 U.S. dollars.

ABBREVIATIONS: MCF = thousand cubic feet; NEI = National Emissions Inventory; SO2 = sulfur dioxide; NOx = nitrogen oxides; PM2.5 = particulate matter smaller than 2.5 microns; VOCs = volatile organic compounds; NH3 = ammonia.
