purpose of these revisions is to update existing air quality rules; make

Act.

SUPPLEMENTARY INFORMATION:  In the final rules section of the Federal
Register, EPA is approving the state’s 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.  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the direct final rule will be withdrawn and all public comments received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.
