Approval and Promulgation of Air Quality Implementation Plans; Montana; Emergency Episode Plan, Columbia Falls, Butte and Missoula Particulate Matter State Implementation Plans, Missoula Carbon Monoxide State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to take direct final action approving State Implementation Plan (SIP) revisions submitted by the State of Montana. The revisions update the State of Montana's Emergency Episode Plan; Columbia Falls, Butte and Missoula Particulate Matter (particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10)) SIPS; and the Missoula Carbon Monoxide (CO) Plan. In the ``Rules and Regulations'' section of this Federal Register, EPA is approving the State's SIP revision as a direct final rule

[[Page 68066]]

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.

DATES: Comments must be received in writing on or before January 5, 2000.

ADDRESSES: Written comments may be mailed to Richard R. Long, Director, Air and Radiation Program, Mailcode 8P-AR, Environmental Protection Agency (EPA), Region VIII, 999 18th Street, Suite 500, Denver, Colorado 80202.
