ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[RME R03-OAR-2004-DC-0001; FRL-7855-4 ]


Approval and Promulgation of Air Quality Implementation Plans; 
District of Columbia; Amendments to the Size Thresholds for Defining 
Major Sources and to the NSR Offset Ratios for Sources of VOC and NOX

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve revisions to the District of Columbia 
(the District) State Implementation Plan (SIP). The revisions reduce 
the size thresholds for defining major sources and increase the new 
source review (NSR) offset ratio requirements for sources of ozone 
precursors to meet the Clean Air Act (CAA) requirements for 1-hour 
ozone nonattainment areas classified as severe. These amendments to the 
District's SIP are required pursuant to the reclassification of the 
Metropolitan Washington, DC 1-hour ozone nonattainment area from 
serious to severe. In the Final Rules section of this Federal Register, 
EPA is approving the District'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the direct final rule will be withdrawn and all public comments 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 27, 2005.

    Instructions: Direct your comments to RME ID No. R03-OAR-2004-DC-

the public docket without change, and may be made available online at

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 RME, regulations.gov 
or e-mail. The EPA RME and the Federal regulations.gov Web sites are 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 RME or 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 
RME index at http://www.docket.epa.gov/rmepub/. 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 RME 
or in hard copy during normal business hours at the Air Protection 
Division, U.S. Environmental Protection Agency, Region III, 1650 Arch

submittal are available at the District of Columbia Department of
