SUPPLEMENTARY INFORMATION: In the Rules and Regulations section of this 
Federal Register, we are approving the maintenance plan for the Ajo 
SO2 nonattainment area. We are also approving the State of 
Arizona's request to redesignate the Ajo area from nonattainment to 
attainment for the primary SO2 NAAQS. We are taking these 
actions without prior proposal because we believe that the revision and 
request are 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 25, 2003.
Deborah Jordan,
Acting Regional Administrator, Region IX.
