This readme contains a summary of the files contained on this disk. These files were developed as part of estimating the costs and emission reductions of attaining a revised ozone National Ambient Air Quality Standard (NAAQS) nationwide. These files contain illustrative analyses that consider a limited number of emission control scenarios that States, Tribes and Regional Planning Organizations might implement to achieve the revised ozone NAAQS. According to the Clean Air Act, EPA must use health-based criteria in setting the NAAQS and cannot consider estimates of compliance cost. EPA is producing this RIA both to provide the public a sense of the benefits and costs of meeting a new ozone NAAQS and to meet the requirements of Executive Order 12866.  These files are strictly illustrative of possible control and cost scenarios, and are not guidance or directives on how to achieve a revised ozone standard.

The materials on this disk are divided into 2 files. All files are in Micrsoft Excel format.  Titles and contents are described below.
Note: 	All files on this disk relate solely to Non-EGU point and Area sources.
	Geographic Areas for these analyses are provided seperately in file named Geographic Areas.xls
	Control Measures data obtained from AirControlNET version 4.1.  Supplemental control measures are included in the RIA in the Appedix to Chapter 3.
