SUMMARY: EPA is proposing to approve the maintenance plan for the San Manuel Area in Pinal and Pima Counties, Arizona, as a revision to the Arizona state implementation plan, and to grant the request submitted by the State to redesignate this area from nonattainment to attainment of the national ambient air quality standards for sulfur dioxide (SO2) for the San Manuel SO2nonattainment area. EPA is proposing this action in accordance with the Clean Air Act.

   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 SO2nonattainment 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.
