SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal 
Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse comments, the 
direct final rule will be withdrawn and public comments will be 
addressed in a subsequent final rule based on this proposed rule. EPA 
will not institute a second comment period. Any parties interested in 
commenting on this action should 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. For additional information, see 
the direct final rule which is located in the Rules section of this 
Federal Register.

    Dated: May 19, 2015.
