End Further Info End Preamble Start Supplemental Information


The draft regulatory text for the 8-hour ozone implementation proposed rule is intended to accompany the June 2, 2003, proposed rule to implement the 8-hour ozone NAAQS. The draft regulatory text contains most of the major elements of the implementation approach, e.g., the transition from the 1-hour to the 8-hour ozone NAAQS and how to implement the Clean Air Act's provisions related to anti-backsliding. In the draft regulatory text, we are not yet addressing the options concerning new source review, i.e., the transitional program and the Clean Air Development Communities program.

The June 2, 2003 proposed rule contains the background discussion for the draft regulatory text. The June 2, 2003 proposal sets forth for comment several options for certain features or plan elements; the draft regulatory text provides the regulatory text for only one of the options being proposed for each feature or element to demonstrate how the regulatory text would appear for that set of options. Selection of a particular option was generally based on the preferences stated in the June 2, 2003 proposal; however, this selection should not be interpreted as a decision by EPA to proceed with that option in the final rule, since comments are still being received on the June 2, 2003, proposal.

The draft regulatory text would also amend 40 CFR part 81 by adding and reserving a new subpart E, which would be used to identify the area designations and classifications for the 1-hour standard in place at the time the 1-hour standard no longer applies to each area; this is being done to implement the proposed rule on anti-backsliding.
