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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: 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.
