40 CFR Part 52

[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 
(PM2.5) have clean data for the 1997 PM2.5 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-

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

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

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
