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.
