[EPA-R03-OAR-2009-0199; FRL-8963-7]


Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Determination of Clean Data for the 1997 Fine Particulate 
Matter Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; reopening of the comment period.

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

SUMMARY: EPA is reopening the comment period for a notice of proposed 
rulemaking (NPR) published on July 31, 2009 (74 FR 38161). In the NPR, 
EPA proposed to determine that the Baltimore, Maryland portion of the 
Hagerstown-Martinsburg nonattainment areas for the 1997 National 
Ambient Air Quality Standard (NAAQS) fine particulate 
(PM<INF>2.5</INF>) have clean data for the 1997 PM<INF>2.5</INF> NAAQS. 
EPA received comments from EarthJustice requesting that the 2009 
monitored data referred to in the proposed rule be made available as 
part of the record and that the proposed rule either be revised or the 
comment period reopened to allow the public to consider the data. EPA 
is, therefore, reopening the comment period and including the data that 
was relied upon for the proposed clean data determination as well as 
the 2009 monitored data. The data relied upon by EPA is now provided in 
a Technical Support Document which is included in the record for this 
rulemaking. EPA is reopening the comment period through October 29, 
2009. All comments received on or before October 29, 2009 will be 
entered into the public record and considered by EPA before taking 
final action on the proposed rule.

DATES: Written comments must be received on or before October 29, 2009.

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

in the public docket without change, and may be made available online 
at http://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 http://www.regulations.gov or e-mail. The http://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 e-mail comment directly to EPA without 
going through http://www.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.
    Docket: All documents in the electronic docket are listed in the  
http://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 http://www.regulations.gov or in hard copy during normal business

Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103.
