Approval and Promulgation of State Implementation Plans: Idaho; 
Boise-Northern Ada County Air Quality Maintenance Area; Second 10-Year 
Carbon Monoxide Maintenance Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the State of Idaho (the State). The Idaho State 
Department of Environmental Quality (IDEQ) submitted the Northern Ada 
County Air Quality Maintenance Area Second 10-year Carbon Monoxide 
Maintenance Plan on February 10, 2011. In accordance with the 
requirements of the Federal Clean Air Act (the Act), EPA is proposing 
to approve the revision because the State adequately demonstrates that 
the Boise-Northern Ada County Air Quality Maintenance Area will 
maintain air quality standards for carbon monoxide (CO) through the 
year 2022.

DATES: Comments must be received on or before September 4, 2012.

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. EPA is approving the State's SIP 
revision as a direct final rule without prior proposal because 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 EPA receives no adverse 
comments, EPA will not take further action on this proposed rule.
    If EPA receives adverse comments, EPA will withdraw the direct 
final rule and it will not take effect. EPA will address all public 
comments in a subsequent final rule based on this proposed rule. 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, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.

    Dated: July 23, 2012.
Dennis J. McLerran,
Regional Adminstrator, EPA Region 10.
