! The unit must fall within the BART time period  an online date after August 7, 1962 and a construction commenced date before August 7, 1977; and ! The combined megawatt capacity of all coal fired units at the plant within this time period is greater than 750 megawatts ( MW).

For units that meets the above criteria, the summary tables provide the following information in a plant specific summary:

! Plant name, plant identification code issued by the Energy Information Administration ( ORIS code), plant location, and the nearest area classified as a Class 1 area under the Clean Air Act ( 156 large national parks and wilderness areas)

! Unit by unit data on online year, MW capacity, emissions, and controls. The emissions data includes both year 2000 emissions and projected emissions in 2010 under current regulatory programs. Year 2001 emissions data represents data reported under the Acid Rain Program. The projected data is based on the IPM 2000 base case results for the model run year 2010. The control technology information also includes currently installed controls and planned controls. Existing controls information reflects data reported by sources under 40 CFR Part 75, with some changes based on Clean Air Markets Division quality assurance activities. The planned control technology information is from the IPM 2000 base case results for the model run year 2010, Internet research, North Carolina's state law compliance plans, and from CAMD information on announced or planned controls.

! There were a number of units with online dates from 1978 through 1985 for which the commenced construction date was uncertain. Information was gathered from various state agencies or other sources to identify the commenced construction date for these units, and the results of that analysis is included in the " Miscellaneous Notes" section of each summary table, where applicable. The Miscellaneous Notes section also includes any other information that might be relevant to the BART unit( s).
