ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R10-OAR-2007-0110; FRL-8330-8]


Approval and Promulgation of Implementation Plans; Idaho and 
Washington; Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve the actions of the Idaho 
Department of Environmental Quality (IDEQ) an the Washington State 
Department of Ecology (Ecology) to address the provisions of Clean Air 
Act section 110(a)(2)(D)(i) for the 8-hour ozone and PM2.5 
National Ambient Air Quality Standards (NAAQS). These provisions 
require each state to submit a State Implementation Plan (SIP) revision 
that prohibits emissions that adversely affect another state's air 
quality through interstate transport. EPA is proposing to approve 
IDEQ's and Ecology's SIP revisions because they adequately address the 
four distinct elements related to the impact of interstate transport of 
air pollutants for their states. These include prohibiting emissions 
that contribute significantly to nonattainment of the NAAQS in another 
state, interfere with maintenance of the NAAQS by another state, 
interfere with plans in another state to prevent significant 
deterioration of air quality, or interfere with efforts of another 
state to protect visibility.

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: June 14, 2007.
Michael F. Gearheard,
Acting Regional Administrator, Region 10.
