SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) revisiOn submitted

received in response to this action, no further activity is contemplated. If EPA receives 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comments, the direct final rule will be withdrawn and all public comments received will be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 rule. EPA will not institute a second

comment period. Any parties interested in commenting on this action should do so at this time.
