Clean Air Act Approval and Promulgation of Air Quality Implementation Plan Revision for Montana; Revisions to the Missoula City-County Air Pollution Control Program

EPA proposes to approve the State implementation the State implementation plan (SIP) revisions regarding the Missoula City-County Air Pollution Control Program, as submitted by the Governor of Montana with a letter dated April 30, 2001. On November 17, 2000, the Montana Board of Environmental Review (MBER) adopted the revisions to the Missoula program rules regarding program authority and administration, definitions, failure to attain standards, emergency episode planning, general provisions, standards for stationary sources (including air quality permit program), outdoor burning, fugitive particulate, solid fuel burning devices, fuels, motor vehicles, enforcement and administrative procedures, and penalties. EPA's approval would make these revisions federally enforceable. In addition, the State requested that rules of the Missoula program that are not appropriate for incorporation into the SIP be removed from the federally approved plan. Finally, the Governor's April 30, 2001 submittal consists of several other revisions to Montana regulations, which will be handled separately. In the Final Rules section of this Federal Register, 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 direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 on this action. Any parties interested in commenting on this action should do so at this time.
