Clean Air Act Approval and Promulgation of PM10 
Implementation Plan for Montana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve the state implementation plan (SIP) 
for the Kalispell, Montana nonattainment area, the Flathead County Air 
Pollution Control Program, and a Board Order setting emission limits at 
nine stationary sources, submitted by the State of Montana with letters 
dated November 25, 1991, January 11, 1994, August 26, 1994, and July 
18, 1995, to achieve attainment of the National Ambient Air Quality 
Standards (NAAQS) for particulate matter with an aerodynamic diameter 
less than or equal to a nominal 10 micrometers (PM10). The SIP was 
submitted to satisfy certain federal Clean Air Act requirements for an 
approvable moderate nonattainment area PM10 SIP for Kalispell. In 
addition, EPA proposes to approve the SIP revisions submitted on August 
26, 1994, and July 18, 1995, to satisfy the Federal Clean Air Act 
requirement to submit contingency measures for the Kalispell and 
Columbia Falls moderate PM10 nonattainment areas. The Columbia 
Falls submittal also incorporates minor revisions to the attainment and 
maintenance demonstrations for the Columbia Falls moderate PM10 
nonattainment area SIP into the Montana SIP. Since the SIP still 
adequately demonstrates timely attainment and maintenance of the PM 
10 national ambient air quality standards (NAAQS), EPA proposes to 
approve these revisions. EPA is also proposing to delete an obsolete 
section of the Code of Federal Regulations (CFR) which applied to 
further requirements for the Butte total suspended particulates (TSP) 
plan.
    In the Final Rules Section of the Federal Register, EPA is 
approving the

[[Page 11170]]
State's SIP revisions, as a direct final rule without prior proposal 
because the Agency views these as noncontroversial revisions 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comments, the direct final will be withdrawn and all public comments 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 
April 18, 1996.

ADDRESSES: All written comments should be addressed to: Richard R. 
Long, Director, Air Program, EPA Region VIII, at the address listed 
below. Information supporting this action can be found at the following 
location: EPA Region VIII, Air Program 999 18th Street, Denver,
