SUPPLEMENTARY INFORMATION: In the ``Rules and Regulations'' section of 
this Federal Register, EPA is approving Wyoming's SIP revision as a 
direct final rule without prior proposal because the Agency 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 must do so 
at this time. Please note that if EPA receives adverse comments 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. 
See the information provided in the Direct Final action of the same 
title which is located in the Rules and Regulations Section of this 
Federal Register.

    Authority: 42 U.S.C. 7401 et seq.
