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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; clarifications.

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

SUMMARY: This document clarifies the summary of the preamble to the 
proposed rule rescinding findings that the 1-hour ozone standard no 
longer applies in certain areas published on October 25, 1999.

FOR FURTHER INFORMATION CONTACT: Annie Nikbakht, Office of Air Quality 
Planning and Standards, Air Quality Strategies and Standards Division, 
Ozone Policy and Strategies Group, MD-15, Research Triangle Park, NC 
27711, [phone].

SUPPLEMENTARY INFORMATION: On October 25, 1999, EPA published the 
preamble to the proposed rule, ``Rescinding Findings That the 1-Hour 
Ozone Standard No Longer Applies in Certain Areas' (64 FR 57424). 
Included in the published summary was the statement regarding our 
proposal to amend 40 CFR 50.9(b) to provide by rule that the 1-hour 
ozone standard will continue to apply to all areas notwithstanding 
promulgation of the 8-hour standard. Inadvertently, additional 
language, elaborating on the proposed amendment to 40 CFR 50.9(b), was 
not included in the published summary of the preamble to the proposed 
rule, although the full text of the preamble and the proposed 
regulatory language contained the additional explanation of our 
proposal. To provide clarification, we today add to that summary the 
following additional language: EPA is proposing that after the 8-hour 
standard has become fully enforceable under part D of title I of the 
CAA and subject to no further legal challenge, the 1-hour standards set 
forth in section 50.9 will no longer apply to an area once EPA 
determines that the area has air quality meeting the 1-hour standard.

    Dated: November 12, 1999.
Robert Perciasepe,
Assistant Administrator for Air and Radiation.
