ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2010-0143; FRL-9759-5]

Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; the 2002 Base Year Inventory for the Baltimore, MD 
Nonattainment Area for the 1997 Fine Particulate Matter National 
Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

[[Page 73387]]

SUMMARY: EPA proposes to approve the fine particulate matter 
(PM2.5) 2002 base year emissions inventory portion of the 
State of Maryland State Implementation Plan (SIP) revision submitted by 
the State of Maryland, through the Maryland Department of the 
Environment (MDE), on June 6, 2008 for Baltimore, Maryland. 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 more detailed description of the 
State submittal and EPA's evaluation is included in a Technical Support 
Document (TSD) prepared in support of this rulemaking action. A copy of 
the TSD is available, upon request, from the EPA Regional Office listed 
in the ADDRESSES section of this document. 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will be withdrawn and all public comments received will be addressed in 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 January 9, 2013.

ADDRESSES: Submit your comments, identified by Docket ID Number EPA-
R03-OAR-2010-0143 by one of the following methods:

submitting comments.

    D. Hand Delivery: At the previously-listed EPA Region III address. 
Such deliveries are only accepted during the Docket's normal hours of

    Instructions: Direct your comments to Docket ID No. EPA-R03-OAR-
2010-0143. EPA's policy is that all comments received will be included 
in the public docket without change, and may be made available online 
at www.regulations.gov, 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 www.regulations.gov or email. The 
www.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 email comment 
directly to EPA without going through www.regulations.gov, your email 
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.
    Docket: All documents in the electronic docket are listed in the 
www.regulations.gov index. Although listed in the index, some 
information is not publicly available, i.e., CBI or other information 
whose disclosure is restricted by statute. Certain other material, such 
as copyrighted material, is not placed on the Internet and will be 
publicly available only in hard copy form. Publicly available docket 
materials are available either electronically in www.regulations.gov or 
in hard copy during normal business hours at the Air Protection 
Division, U.S. Environmental Protection Agency, Region III, 1650 Arch 
Street, Philadelphia, Pennsylvania 19103. Copies of the State submittal 
are available at the Maryland Department of the Environment, 1800 
Washington Boulevard, Suite 705, Baltimore, Maryland 21230.
