SUPPLEMENTARY INFORMATION: In the Rules and Regulations section of this 
Federal Register, we are approving the maintenance plan for the Morenci 
SO2 nonattainment area. We are also approving the State of 
Arizona's request to redesignate the Morenci 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: March 30, 2004.
Laura Yoshii,
Acting Regional Administrator, Region IX.
