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 San Manuel SO2 nonattainment area 
and to approve the State of Arizona's request to redesignate the San 
Manuel area from nonattainment to attainment. 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.
