Data is compressed. Requires 2 GB disk space to decompress all the files. Documentation is on the disc. Each issue contains emissions data for one quarter. Issues are not cumulative.
Pollutants monitored include sulfur dioxide, nitrogen oxides, and carbon dioxide.
Also included is general operating data, including operating time, heat input, and gross unit load. There is also information on the unit's monitoring plan, and the results of tests required to be performed by the source to insure that its monitoring equipment is functioning properly. Electric utilities, energy consultants, and power marketing companies can use EPA Acid Rain Program emissions data to project future SO2 allowance costs and availability. Academic institutions can perform data modeling to evaluate environmental benefits and estimate health effects of SO2 reductions.
