Abstract
The Environmental Protection Agency (EPA) is approving the second 10-year maintenance plans for the Ajo and Morenci areas in Arizona for the 1971 National Ambient Air Quality Standards (NAAQS or "standards") for sulfur dioxide (SO<INF>2</INF>), and correcting an error in the description of the Ajo SO<INF>2</INF> maintenance area in the Code of Federal Regulations. Elsewhere in this Federal Register, we are proposing approval and soliciting written comment on these actions. If we receive adverse comments on this direct final rule, resulting in withdrawal of the entire rule or any part(s) of it, we will address those comments when we finalize the proposal. The EPA does not plan to institute a second comment period on this action. Any parties interested in commenting must do so at this time.
