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 attainment determination as a direct final rule without prior proposal because EPA views this as a noncontroversial action 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 22, 2010.

Dennis J. McLerran,

Regional Administrator, EPA, Region 10.
