SUMMARY: EPA is proposing to find that the Phoenix metropolitan 
nonattainment area in Arizona has attained the National Ambient Air 
Quality Standard (NAAQS) for carbon monoxide (CO) by its Clean Air Act 
deadline of December 31, 2000. The Phoenix area has had no exceedances 
of the CO standard since 1996, and has six years of clean air quality 
data.

of Air Planning (AIR-2), U.S. Environmental Protection Agency, Region

We prefer electronic comments.

SUPPLEMENTARY INFORMATION: Throughout this document, the words ``we,'' 
``us,'' and ``our'' mean U.S. EPA.
    Based on ambient air quality data recorded on Phoenix area monitors 
during 1999 and 2000, we are proposing to find that the area has met 
the CO standard by its statutory deadline of December 31, 2000.
    In the Rules and Regulations section of this Federal Register, we 
are making this attainment finding in a direct final action without 
prior proposal because we believe this action is not

controversial. If we receive adverse comments, however, we will publish 
a timely withdrawal of the direct final rule and address the comments 
in subsequent action based on this proposed rule.
    We do not plan to open a second comment period, so anyone 
interested in commenting should do so at this time. If we do not 
receive adverse comments, no further activity is planned. For further 
information, please see the direct final action.

    Dated: September 9, 2003.
