SUPPLEMENTARY INFORMATION: In the Rules and Regulations section of this 
Federal Register, we are taking direct final action to approve the 
maintenance plan for the Miami SO2 nonattainment area and to 
approve the State of Arizona's request to redesignate the Miami area 
from nonattainment to attainment. We are also taking direct final 
action to correct the boundary of the Miami SO2 
nonattainment area. We are taking these actions without prior proposal 
because we believe these SIP revisions 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 rule in this Federal Register.

    Authority: 42 U.S.C. 7401 et seq.

    Dated: December 22, 2006.
Sally Seymour,
Acting Regional Administrator, Region IX.
