CFR Citation: 40 CFR Part 52

DOCUMENT ID: [R05-OAR-2004-IN-0003; FRL-7806-6]

NOTICE: PROPOSED RULES

ACTION: Air quality implementation plans; approval and promulgation; various States:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Approval and Promulgation of Implementation Plans; Indiana

DATES: Written comments must be received on or before September 27, 2004.

DOCUMENT SUMMARY: The EPA is proposing to approve Indiana's August 6, 2004, submittal of revised mobile emission inventories and 2005 and 2007 motor vehicle emissions budgets (MVEBs) which have been developed using MOBILE6, an updated model for calculating mobile emissions of ozone precursors. These inventories and associated motor vehicle emissions budgets are part of the 1hour ozone attainment plan approved for the Northwest Indiana area. The Northwest Indiana area consists of Lake and Porter Counties in Indiana. The State's submittal meets a commitment to revise and resubmit the MVEBs using MOBILE6 methods within two years following the release of MOBILE6 provided that transportation conformity is not determined without adequate MOBILE6based MVEBs during the second year.

In the final rules section of this Federal Register, EPA is approving the SIP revision as a direct final rule without prior proposal, because EPA views this as a noncontroversial revision and anticipate 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 proposed rule, no further activity is contemplated in relation to this proposed rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 on this action. Any parties interested in commenting on this action should do so at this time.

SUMMARY: Indiana,
