ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[R05-OAR-2004-MI-0003; FRL-7865-1]


Approval and Promulgation of Maintenance Plan Revisions; Michigan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

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.

ADDRESSES: Submit comments, identified by Regional Material in EDocket 
(RME) ID No. R05-OAR-2004-IL-0003 by one of the following methods:
    Federal eRulemaking Portal: http://www.regulations.gov. Follow the 
on-line instructions for submitting comments.
    Agency Web site: http://docket.epa.gov/rmepub/index.jsp. RME, EPA's 
electronic public docket and comment system, is EPA's preferred method 
for receiving comments. Once in the system, select ``quick search,'' 
then key in the appropriate RME Docket identification number. Follow 
the online instructions for submitting comments.
    E-mail: [email protected].
    Fax: (312) 886-5824.
    Mail: You may send written comments to: John M. Mooney, Chief, 
Criteria Pollutant Section, (AR-18J), U.S. Environmental Protection 
Agency, 77 West Jackson Boulevard, Chicago, Illinois 60604.
    Hand delivery: Deliver your comments to: John M. Mooney, Chief, 
Criteria Pollutant Section (AR-18J), U.S. Environmental Protection 
Agency, Region 5, 77 West Jackson Boulevard, 18th floor, Chicago, 
Illinois 60604.
    Such deliveries are only accepted during the Regional Office's 
normal hours of operation. The Regional Office's official hours of

    Instructions: Direct your comments to RME ID No. R05-OAR-2004-IL-
0003. EPA's policy is that all comments received will be included in 
the public docket without change, including any personal information 
provided, unless the comment includes information claimed to be 
Confidential Business Information (CBI) or other information whose 
disclosure is restricted by statute. Do not submit information that you 
consider to be CBI or otherwise protected through RME, regulations.gov, 
or e-mail. The EPA RME Web site and the federal regulations.gov Web 
site are ``anonymous access'' systems, which means EPA will not know 
your identity or contact information unless you provide it in the body 
of your comment. If you send an e-mail comment directly to EPA without 
going through RME or regulations.gov, your e-mail address will be 
automatically captured and included as part of the comment that is 
placed in the public docket and made available on the Internet. If you 
submit an electronic comment, EPA recommends that you include your name 
and other contact information in the body of your comment and with any 
disk or CD-ROM you submit. If EPA cannot read your comment due to 
technical difficulties and cannot contact you for clarification, EPA 
may not be able to consider your comment. Electronic files should avoid 
the use of special characters, any form of encryption, and be free of 
any defects or viruses. For additional instructions on submitting 
comments, go to Section I(B) of the SUPPLEMENTARY INFORMATION section 
of this document.
    Docket: All documents in the electronic docket are listed in the 
RME index at http://www.epa.gov/rmepub/index.jsp. Although listed in 
the index, some information is not publicly available, i.e., CBI or 
other information whose disclosure is restricted by statute. Publicly 
available docket materials are available either electronically in RME 
or in hard copy at Environmental Protection Agency, Region 5, Air and 
Radiation Division, 77 West Jackson Boulevard, Chicago, Illinois 60604.

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.

[[Page 4080]]

    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.

III. Where Can I Find More Information About This Proposal and the 
Corresponding Direct Final Rule?

    For additional information, see the Direct Final Rule which is 
located in the Rules section of this Federal Register. Copies of the 
request and the EPA's analysis are available electronically at RME or 
in hard copy at the above address. (Please telephone Anthony Maietta at
