# SUPPLEMENTARY INFORMATION:

                    In the final rules section of the                     **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 revision amendment and anticipates no relevant adverse comments to this action. The revisions will not increase emissions and do not affect the stringency of the control requirement. Additionally, the revisions have gone through the Missouri approval process, including a public hearing and opportunity for public comment. EPA was the only party to provide comments during Missouri's comment period. Therefore, we do not anticipate any adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. 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 EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts 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: April 26, 2007.
