For example, the coal-fired plants are assumed to be 500-megawatt facilities, each with a capacity factor of 75.0 percent and an efficiency rating of 34.5 percent. Also assumed is the use of electrostatic precipitators to control particulates (99.5 percent effectiveness), scrubbers to control SO2 emissions (90 percent effectiveness), and low-NOx burners to control emissions of oxides of nitrogen. The coal used in the East is assumed to have a sulfur content of 2.1 percent by weight, while that used in the West is assumed to contain 0.7 percent sulfur by weight.

(25) This discussion focuses on electric utilities. Under the provisions of the CAAA, control of emissions from nonutility generators may vary from State to State and according to facility size and startup date. (26) The sections of the CAAA that address urban air quality and acid rain also have indirect impacts on greenhouse gases. However, those impacts are not discussed in this article.

(29) Specifically, a unit affected by Phase I requirements is allocated allowances equal to its annual average fuel consumption during the period 1985 through 1987, multiplied by an emissions rate of 2.5 pounds of SO2 per million Btu. Phase II allowances are computed by using the same fuel consumption number multiplied by an emissions rate of 1.2 pounds of SO2 per million Btu. (30) Energy Efficiency and Renewable Energy, p. 9. (31) Low-sulfur coal is defined as coal that, when burned, meets an emission standard of 1.2 pounds or less of SO2 per million Btu. (32) A.D.

(34) EIA forecasts that approximately 20 percent (net) of the West's allowances will be transferred to eastern facilities in 2005.

The Interior Region is Arkansas, Illinois, Indiana, Iowa, Kansas, western Kentucky, Louisiana, Missouri, Oklahoma, and Texas. The Appalachian Region is Alabama, eastern Kentucky, Maryland, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia. (37) EPA has set the ozone standard at 0.12 parts per million daily maximum one-hour average concentration, not to be exceeded more than once per year.

(39) The CAAA established the Ozone Transport Commission (OTC) to coordinate the efforts of States in the Northeast to solve their ozone problems. State-level coordination is necessary because ozone and its precursors, VOC's and NOx, can be transported over long distances by winds. The OTC includes 12 Northeastern and mid-Atlantic States, the District of Columbia, and the EPA.
