Approval and Promulgation of Air Quality Implementation Plans; La 
Grande PM10 Maintenance Plan and Redesignation Request

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a PM10 State 
Implementation Plan (SIP) maintenance plan revision for the La Grande, 
Oregon nonattainment area and to redesignate the area from 
nonattattainment to attainment for PM10. PM10 air 
pollution is suspended particulate matter with a nominal diameter less 
than or equal to a nominal ten micrometers. EPA is proposing to approve 
the SIP revision and redesignation request because the State adequately 
demonstrates that the control measures being implemented in the La 
Grande area result in maintenance of the PM10 National 
Ambient Air Quality Standards and all other requirements of the Clean 
Air Act for redesignation to attainment are met.

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: February 24, 2006.
Julie M. Hagensen,
Acting Regional Administrator, Region 10.
