Summary

The Environmental Protection Agency (EPA) is proposing to approve a December 19, 2003 request from Michigan for a State Implementation Plan (SIP) revision of the Southeast Michigan carbon monoxide (CO) maintenance plan. The CO maintenance plan revision establishes a new on-road emissions inventory for the years 1996 and 2010. The revision also establishes a new transportation conformity motor vehicle emissions budget (MVEB) for the year 2010. The emission inventory and MVEB updates are designed to maintain the National Ambient Air Quality Standards (NAAQS) for CO as required by the CAA. 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 anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If we do not receive any adverse comments in response to these direct final and proposed rules, we do not contemplate taking any further action in relation to this proposed rule. If EPA receives adverse comments, we will withdraw the direct final rule and will respond to all public comments 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.

Dates

Written comments must be received on or before February 28, 2005.

Where Can I Find More Information About This Proposal and the Corresponding Direct Final Rule? I. General Information A. Does This Action Apply to Me? This action applies to the Southeast Michigan CO maintenance area, which consists of portions of Macomb, Wayne, and Oakland Counties. B. What Should I Consider as I Prepare My Comments for EPA? 1. Submitting CBI. Do not submit CBI to EPA through RME, regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 2. Tips for Preparing Your Comments. When submitting comments, remember to: a. Identify the rulemaking by docket number and other identifying information (subject heading, Federal Register date and page number). b. Follow directions—The agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number. c. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes. d. Describe any assumptions and provide any technical information and/or data that you used. e. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced. f. Provide specific examples to illustrate your concerns, and suggest alternatives. g. Explain your views as clearly as possible, avoiding the use of profanity or personal threats. h. Make sure to submit your comments by the comment period deadline identified. II. What Action Is EPA Taking Today? EPA is proposing to approve a December, 19, 2003 request from Michigan to revise the Southeast Michigan CO maintenance plan. In a separate Direct Final Rule in today's Federal Register , EPA is approving the December 19, 2003 request. The Southeast Michigan CO maintenance area consists of portions of Oakland, Macomb, and Wayne Counties. As a result of today's action, the 1996 base year on-road emissions inventory, forecast year 2010 emissions inventory, and the 2010 MVEB will be updated to meet EPA's requirement to use the Mobile6 emissions factor model to determine conformity to the CO maintenance SIP. By approving the revision, EPA ensures that future emission forecasts for conformity analyses in the Southeast Michigan CO maintenance area will be compared to budgets that are based on similar inputs and the same version of the Mobile model.
