Approval and Promulgation of Air Quality Implementation Plans; 
Wyoming; Revisions to the Wyoming Air Quality Standards and Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

[[Page 19921]]

SUMMARY: EPA is proposing to approve two State Implementation Plan 
(SIP) revisions submitted by the State of Wyoming on September 11, 
2008. Wyoming has revised its Air Quality Standards and Regulations, 
specifically Chapter 1, Section 5, Unavoidable equipment malfunction, 
and Chapter 1, Section 6, Credible evidence. EPA is taking this action 
under section 110 of the Clean Air Act. In the ``Rules and 
Regulations'' section of this Federal Register, EPA is approving the 
State'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 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.

DATES: Written comments must be received on or before May 17, 2010.
