SUPPLEMENTARY INFORMATION:

In the Final Rules section of this Federal Register, EPA is approving Indiana's SO₂ 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 EPA does not receive adverse comments in response to this rule, no further activity is contemplated. If EPA receives adverse comments, EPA will withdraw the direct final rule and will address all public comments received 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 can 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.

Regional Administrator, Region 5.
