Clean Air Act Approval and Promulgation of State Implementation Plan for Montana; Libby Moderate PMINF10 Nonattainment Area

EPA proposes to approve the State implementation plan (SIP) revisions submitted by the State of Montana on March 15, 1995 to satisfy the Federal Clean Air Act requirement to submit contingency measures for the Libby moderate PM 10 (particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers) nonattainment area. The March 15, 1995 submittal also recodified the Lincoln County regulations. In addition, EPA proposes to approve a SIP revision submitted by the Governor of Montana on May 13, 1996, which included revisions to the Lincoln County regulations regarding open burning. EPA is proposing to approve these SIP revisions because they are consistent with the applicable requirements of the Clean Air Act, as amended (Act), and EPA guidance. In the Final Rules Section of this Federal Register, EPA is approving the State's SIP revisions as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision amendment and anticipates no adverse comments. A detailed rationale for EPA's approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity
