Throughout this document, “we,” “us” and “our” refer to the EPA. This proposal addresses the second ten-year maintenance plans submitted by the Arizona Department of Environmental Quality to address the 1971 SO2 NAAQS in the Ajo and Morenci maintenance areas, AZ. In the Rules and Regulations section of this Federal Register, we are approving these second ten-year maintenance plans in a direct final action 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. If we receive adverse comment on a distinct provision of this rulemaking, i.e., our action regarding only one maintenance plan, we will publish a timely withdrawal in the Federal Register indicating which provisions we are withdrawing. The provisions that are not withdrawn, i.e., our approval of the other maintenance plan that is not the subject of an adverse comment, will become effective on the date set out above, notwithstanding adverse comment on the other maintenance plan.
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.
