ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2015-0470; FRL-9934-90-Region 4]

Approval and Promulgation of Air Quality Implementation Plans; 
Pennsylvania; Approval of the Base Year Emissions Inventory for the 
Liberty-Clairton Nonattainment Area for the 2006 24-Hour Fine 
Particulate Matter Standard and Approval of Transportation Conformity 
Insignificance Findings for the 1997 Annual and 2006 24-Hour Fine 
Particulate Matter Standards for the Liberty-Clairton Nonattainment 
Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) proposes to approve 
the State Implementation Plan (SIP) revision submitted by the 
Commonwealth of Pennsylvania for the purpose of meeting the statutory 
emissions inventory requirements for the Liberty-Clairton nonattainment 
area (hereafter ``the Liberty-Clairton Area'' or ``the Area'') with 
respect the 2006 24-hour fine particulate matter (PM2.5) 
National Ambient Air Quality Standard (NAAQS or standard). The SIP 
revision consists of the 2007 base year emissions inventory for the 
Liberty-Clairton Area for the 2006 24-hour PM2.5 NAAQS. EPA 
is also proposing to approve a SIP revision consisting of 
Pennsylvania's determinations for both the 1997 annual and 2006 24-hour 
PM2.5 standards that onroad emissions of PM2.5 
and nitrogen oxides (NOX) are insignificant contributors to 
PM2.5 concentrations in the Liberty-Clairton Area for 
transportation conformity purposes. In the Final Rules section of this 
Federal Register, EPA is approving Pennsylvania'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. 
The publication of this document starts a 30-day public comment period 
on the adequacy of the submitted motor vehicle emission inventories. 
This comment period is concurrent with the comment period on this 
direct final rulemaking action. Any comments on the motor vehicle 
emission inventories should be submitted to the docket for this 
rulemaking. A detailed rationale for the approval is set forth in the 
direct final rule. Additionally, a more detailed description of the 
state submittal and EPA's evaluation is included in the Technical 
Support Documents (TSDs) prepared in support of this rulemaking action. 
A copy of the TSDs are available, upon request, from the EPA Regional 
Office listed in the ADDRESSES section of this document or is also 
available electronically within the Docket for this rulemaking action. 
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

[[Page 59704]]

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 November 2, 2015.

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

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

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
