Start Preamble


Environmental Protection Agency (EPA).


Proposed rule


EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the Governor of Montana on June 26, 1997, and June 13, 2000. (Portions of the June 26, 1997 submittal were withdrawn by the Governor of Montana on February 8, 1999). These revisions contain an inventory of emissions for Whitefish and establish and require continuation of all control measures adopted and implemented for reductions of particulate aerodynamic diameter less than or equal to 10 micrometers (PM10) in order to attain the PM10 National Ambient Air Quality Standards (NAAQS) in Whitefish. Using the PM10 clean data areas approach, we are proposing to approve the control measures and the emissions inventory that were submitted as part of the PM10 nonattainment area SIP for Whitefish. This action is being taken under section 110 of the Clean Air Act (CAA or Act).

EPA is approving the State's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule. If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting must 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 may 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.
