                    In the final rules section of the                     **Federal Register**                    , EPA is approving the state's SIP revision as a direct final rule                           ( print page 10627)                        without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no relevant adverse comments to this action.

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**                    .
