ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[MT6-1-5485b and MT20-1-6355b; FRL-5053-8]

 

Approval and Promulgation of Air Quality Implementation Plans; 
Montana; State Implementation Plan for Libby PM10 Nonattainment 
Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve the State implementation plan (SIP) 
submitted by the State of Montana 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 by Montana to satisfy certain 
federal requirements for an approvable nonattainment area PM10 SIP 
for Libby. In the final rules section of this Federal Register, EPA is 
approving the State's SIP revision, 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 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receives adverse comments, the direct final rule will be withdrawn and 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 
September 29, 1994.

ADDRESSES: Written comments should be addressed to Meredith A. Bond at 
the EPA Regional Office listed below. Copies of the documents relevant 
to this proposed rule are available for public inspection during normal 
business hours at the following locations. The interested persons 
wanting to examine these documents should make an appointment with the 
appropriate office at least 24 hours before the visiting day.
