[MT-001-0002b, MT-001-0003b; FRL-5934-4]

Approval and Promulgation of Air Quality Implementation Plans;
Montana; 1990 Base Year Carbon Monoxide Emission Inventories for
Montana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing approval of the 1990 base year carbon
monoxide (CO) emission inventories for Missoula, Billings, and Great
Falls that were submitted by the State to satisfy certain requirements
of the Clean Air Act (CAA), as amended in 1990. In the Final Rules
Section of this Federal Register, EPA is approving the State's State
Implementation Plan (SIP) revision as a direct final rule without prior
proposal because the Agency views this as a noncontroversial 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comments, the direct final rule will be withdrawn and all public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.

DATES: Comments on this proposed rule must be received in writing by
January 14, 1998.

ADDRESSES: Written comments should be addressed to: Richard R. Long,
Director, Air Program (8P2-A), United States Environmental Protection
