Determination of Attainment, Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Indiana; Redesignation of Allen County 8-Hour Ozone Nonattainment Area to Attainment for Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: On May 30, 2006, the State of Indiana, through the Indiana Department of Environmental Management (IDEM), submitted, in final: A request to redesignate the 8-hour ozone National Ambient Air Quality Standard (NAAQS) nonattainment area of Allen County, Indiana, to attainment for the 8-hour ozone NAAQS; and a request for EPA approval of an Indiana State Implementation Plan (SIP) revision containing a 14- year maintenance plan for Allen County. Today, EPA is proposing to determine that the Allen County, Indiana ozone nonattainment area has attained the 8-hour ozone NAAQS. This determination is based on three years of complete, quality-assured ambient air quality monitoring data for the 2003-2005 ozone seasons that demonstrate that the 8-hour ozone NAAQS has been attained in the area. EPA is also proposing to approve Indiana's request to redesignate the area to attainment for the 8-hour ozone standard and the State's maintenance plan SIP revision. EPA's proposed approval of the 8-hour ozone redesignation request is based on its determination that Allen County, Indiana has met the criteria for redesignation to attainment specified in the Clean Air Act. EPA is also proposing to approve, for purposes of transportation conformity, the motor vehicle emission budgets (MVEBs) for the year 2020 that are contained in the 14-year 8-hour ozone maintenance plan for Allen County.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
