ENVIRONMENTAL PROTECTION AGENCY

Federal Register Volume 80, Issue 191 (October 2, 2015)

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 (PM<INF>2.5</INF>) 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 PM<INF>2.5</INF> NAAQS. EPA is also proposing to approve a SIP revision consisting of Pennsylvania's determinations for both the 1997 annual and 2006 24-hour PM<INF>2.5</INF> standards that onroad emissions of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>) are insignificant contributors to PM<INF>2.5</INF> 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

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.

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 Pennsylvania Department of Environmental 
Protection, Bureau of Air Quality Control, P.O. Box 8468, 400 Market 
Street, Harrisburg, Pennsylvania 17105; and at the Allegheny County

Quality, 301 39th Street, Pittsburgh, Pennsylvania 15201.
