Rescinding Findings That the 1-Hour Ozone Standard No Longer Applies in Certain Areas

概要

On October 25, 1999, the EPA published the preamble to this proposed rule, proposing to rescind its prior findings that the 1-hour ozone national ambient air quality standard (NAAQS) and its accompanying designations and classifications no longer apply in certain areas. Under the proposal, the designations and classifications that previously applied in such areas with respect to the 1-hour standard would be reinstated. Today's action includes the proposed regulatory language for Part 81, as was noted in the published preamble would follow in a subsequent Federal Register.
