ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[MD161-3110b; FRL-7648-2]


Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Revisions to the 2005 ROP Plan for the Cecil County Portion 
of the Philadelphia-Wilmington-Trenton 1-Hour Ozone Nonattainment Area 
to Reflect the Use of MOBILE6

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve State Implementation Plan (SIP) 
revisions submitted by the State of Maryland. These revisions amend the 
2005 rate-of-progress (ROP) plan in the Maryland SIP for the Cecil 
County portion of the Philadelphia-Wilmington-Trenton nonattainment 
severe 1-hour ozone nonattainment area (the Philadelphia area). The 
intent of these revisions is to update Cecil County's 2005 ROP plan's 
mobile emissions inventories and motor vehicle emissions budgets 
(MVEBs) to reflect the use of MOBILE6. 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 action, 
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the direct final rule will be withdrawn and all public comments 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.

DATES: Comments must be received in writing by May 17, 2004.

ADDRESSES: Submit your comments, identified by MD161-3110 by one of the 
following methods:
    A. Federal eRulemaking Portal: http://www.regulations.gov. Follow 
the on-line instructions for submitting comments.
    B. E-mail: [email protected].
    C. Mail: Larry Budney, Mailcode 3AP23, U.S. Environmental 
Protection Agency, Region III, 1650 Arch Street, Philadelphia,

     D. Hand Delivery: At the previously-listed EPA Region III address. 
Such deliveries are only accepted during the Docket's normal hours of 
operation, and special arrangements should be made for deliveries of 
boxed information.
    Instructions: Direct your comments to Docket ID No. MD161-3110. 
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 regulations.gov or e-
mail. The Federal regulations.gov Web site is an ``anonymous access'' 
system, 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 
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.
    Copies of the documents relevant to this action are available for 
public inspection during normal business hours at the Air Protection 
Division, U.S. Environmental Protection Agency, Region III, 1650 Arch 
Street, Philadelphia, Pennsylvania 19103; and the Maryland Department 
of the Environment, 1800 Washington Boulevard, Suite 705, Baltimore, 
Maryland, 21230.
