40 CFR Part 52

[MT26-7-6874b; FRL-5609-9]


Clean Air Act Approval and Promulgation of State Implementation 
Plan for Montana; Libby Moderate PM10 Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: 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 PM10 (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 is contemplated and the direct final rule will become 
effective. 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be withdrawn and all public comments received will be addressed in a 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 document should do so now.

DATES: Comments on this proposed rule must be received in writing by 
October 30, 1996.

ADDRESSES: Written comments on this action should be addressed to Vicki 
Stamper, 8P2-A, at the EPA Regional Office listed below. Copies of the 
State's submittals and documents relevant to this proposed rule are 
available for inspection during normal business hours at the following 
locations: Air Programs Branch, Environmental Protection Agency, Region 
VIII, 999 18th Street, Suite 500, Denver, Colorado 80202-2405; and 
Montana Department of Environmental Quality, Air Quality Division, 
Cogswell Building, Helena, Montana 59620-0901.

Final action which is located in the Rules Section of this Federal 
Register.

    Dated: August 29, 1996.
