ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R10-OAR-2013-0421; FRL-9907-21-Region 10]

Approval and Promulgation of State Implementation Plans: Alaska; 
Anchorage Carbon Monoxide Limited Maintenance Plan and State 
Implementation Plan Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The State of Alaska (the State) submitted two State 
Implementation Plan (SIP) revisions to the Anchorage Transportation 
Control Program, Anchorage Carbon Monoxide (CO) Maintenance Plan. On 
September 20, 2011, the State submitted a SIP revision (2011 Submittal) 
that updated Anchorage's carbon monoxide (CO) motor vehicle emissions 
budget in the Anchorage CO maintenance area using the EPA's Motor 
Vehicle Emission Simulator model. On April 22, 2013, the State 
submitted a SIP revision (2013 Submittal) to satisfy the Clean Air Act 
(CAA) section 175A(b) requirement for a second 10-year maintenance plan 
for the Anchorage CO maintenance area in the form of a limited 
maintenance plan (LMP). This LMP addresses maintenance of the CO 
National Ambient Air Quality Standards for a second 10-year period, 
beyond redesignation of the area to attainment, through 2024. The EPA 
is proposing to approve both the 2013 Submittal and portions of the 
2011 Submittal that are not superseded by the 2013 Submittal. The EPA 
is proposing to approve these SIP revisions because the State has 
demonstrated that they are consistent with the CAA.

SUPPLEMENTARY INFORMATION: For further information, please see the 
direct final action, of the same title, which is located in the Rules 
section of this Federal Register. The EPA is simultaneously approving 
the State's SIP revision as a direct final rule without prior proposal 
because the EPA views this as a noncontroversial SIP revision and 
anticipates no adverse comments. A detailed rationale for the approval 
is set forth in the preamble to the direct final rule. If the EPA 
receives no adverse comments, the EPA will not take further action on 
this proposed rule.
    If the EPA receives adverse comments, the EPA will withdraw the 
direct final rule and it will not take effect. The EPA will address all 
public comments in a subsequent final rule based on this proposed rule. 
The EPA will not institute a second comment period on this action. Any 
parties interested in commenting on this action should do so at this 
time. Please note that if we receive adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, the EPA may adopt as final those 
provisions of the rule that are not the subject of an adverse comment.

    Dated: February 13, 2014.
Dennis J. McLerran,
Regional Administrator, Region 10.
