ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2012-0982; FRL-9777-3]

Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Amendments to Maryland's Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) 
revision submitted by the State of Maryland for the purpose of adopting 
through incorporation by reference the national ambient air quality 
standards (NAAQS). 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 EPA 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rule will be withdrawn and all public comments received will be 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 March 13, 2013.

ADDRESSES: Submit your comments, identified by Docket ID Number EPA-
R03-OAR-2012-0982 by one of the following methods:
    A. www.regulations.gov. Follow the on-line instructions for 
submitting comments.

    Instructions: Direct your comments to Docket ID No. EPA-R03-OAR-
2012-0982. 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 ww.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.
