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

EPA approves 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 makes 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.
