ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[DE072 1042b; FRL-7593-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Delaware; MOBILE6-based Motor Vehicle Emission Budgets for the Delaware 
Portion of the Philadelphia-Wilmington-Trenton Ozone Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve a revision to the Delaware State 
Implementation Plan (SIP). Specifically, EPA is proposing approving 
amendments to the 2005 highway (on road) motor vehicle emission 
inventory for the Delaware portion of the Philadelphia-Wilmington-
Trenton area's (the Philadelphia area) 1-hour ozone attainment plan as 
a revision to the Delaware SIP. This revision also serves to amend the 
2005 motor vehicle emission budgets (MVEBs) used for determining 
transportation conformity under the Clean Air Act. The revised MVEBs 
were developed using MOBILE6, the most recent version of EPA's mobile 
source emission factor model. Revision of the MVEBs was a requirement 
of EPA's prior approval of Delaware's 1-hour ozone attainment 
demonstration plan for the Philadelphia severe ozone nonattainment 
area. In the final rules section of this Federal Register, EPA is 
approving Delaware'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will be withdrawn and public comments received will be addressed in a 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 January 5, 2004.

ADDRESSES: Comments may be submitted either by mail or electronically. 
Written comments should be mailed to Robert Kramer, Chief, Energy, 
Radiation and Indoor Environment Branch, Mailcode 3AP23,

SUPPLEMENTARY INFORMATION: For further information, please see the 
information provided in the direct final action, with the same title, 
that is located in the ``Rules and Regulations'' section of this 
Federal Register publication. You may submit comments either 
electronically or by mail. To ensure proper receipt by EPA, identify 
the appropriate rulemaking identification number DE072-1042 in the 
subject line on the first page of your comment. Please ensure that your 
comments are submitted within the specified comment period. Comments 
received after the close of the comment period will be marked ``late.'' 
EPA is not required to consider these late comments.
    1. Electronically. If you submit an electronic comment as 
prescribed below, EPA recommends that you include your name, mailing 
address, and an e-mail address or other contact information in the body 
of your comment. Also include this contact information on the outside 
of any disk or CD ROM you submit, and in any cover letter accompanying 
the disk or CD ROM. This ensures that you can be identified as the 
submitter of the comment and allows EPA to contact you in case EPA 
cannot read your comment due to technical difficulties or needs further 
information on the substance of your comment. EPA's policy is that EPA 
will not edit your comment, and any identifying or contact information 
provided in the body of a comment will be included as part of the 
comment that is placed in the official public docket. 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.
    i. E-mail. Comments may be sent by electronic mail (e-mail) to 
[email protected], attention DE072-1042. EPA's e-mail system is not 
an ``anonymous access'' system. If you send an e-mail comment directly 
without going through Regulations.gov, EPA's e-mail system 
automatically captures your e-mail address. E-mail addresses that are 
automatically captured by EPA's e-mail system are included as part of 
the comment that is placed in the official public docket.
    ii. Regulations.gov. Your use of Regulation.gov is an alternative 
method of submitting electronic comments to EPA. Go directly to http://www.regulations.gov, then select ``Environmental Protection Agency'' at 
the top of the page and use the ``go'' button. The list of current EPA 
actions available for comment will be listed. Please follow the online 
instructions for submitting comments. The system is an ``anonymous 
access'' system, which means EPA will not know your identity, e-mail 
address, or other contact information unless you provide it in the body 
of your comment.
    iii. Disk or CD ROM. You may submit comments on a disk or CD ROM 
that you mail to the mailing address identified in the ADDRESSES 
section of this document. These electronic submissions will be accepted 
in WordPerfect, Word or ASCII file format. Avoid the use of special 
characters and any form of encryption.
    2. By Mail. Written comments should be addressed to the EPA 
Regional office listed in the ADDRESSES section of this document.
    For public commenters, it is important to note that EPA's policy is 
that public comments, whether submitted electronically or in paper, 
will be made available for public viewing at the EPA Regional Office, 
as EPA receives them and without change, unless the comment contains 
copyrighted material, confidential business information (CBI), or other 
information whose disclosure is restricted by statute. When EPA 
identifies a comment containing copyrighted material, EPA will provide 
a reference to that material in the version of the comment that is 
placed in the official public rulemaking file. The entire printed 
comment, including the copyrighted material, will be available at the 
Regional Office for public inspection.

Submittal of CBI Comments

    Do not submit information that you consider to be CBI 
electronically to EPA. You may claim information that you submit to EPA 
as CBI by marking any part or all of that information as CBI (if you 
submit CBI on disk or CD ROM, 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 CBI). Information so marked will not be 
disclosed except in accordance with procedures set forth in 40 CFR part 
2. In addition to one complete version of the comment that includes any 
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 
official public regional rulemaking file. If you submit the copy that 
does not contain CBI on disk or CD ROM, mark the outside of the disk or 
CD ROM clearly that it does not contain CBI. Information not marked as 
CBI will be included in the public file and available for public 
inspection without prior notice. If you have any questions about CBI or 
the procedures for claiming CBI, please consult the person identified 
in the FOR FURTHER INFORMATION CONTACT section.

Considerations When Preparing Comments to EPA

    You may find the following suggestions helpful for preparing your 
comments:
    1. Explain your views as clearly as possible.
    2. Describe any assumptions that you used.
    3. Provide any technical information and/or data you used that 
support your views.
    4. If you estimate potential burden or costs, explain how you 
arrived at your estimate.
    5. Provide specific examples to illustrate your concerns.
    6. Offer alternatives.
    7. Make sure to submit your comments by the comment period deadline 
identified.
    8. To ensure proper receipt by EPA, identify the appropriate 
regional file/rulemaking identification number in the subject line on 
the first page of your response. It would also be helpful if you 
provided the name, date, and Federal Register citation related to your 
comments.
    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.
