ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[MT31-1-7007b; FRL-5275-2]

Clean Air Act Approval and Promulgation of PM10 State

Implementation Plan for Montana; Missoula Air Pollution Control Program

Regulations

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 with a letter dated March

3, 1995. This submittal consists of several revisions to Missoula City-

County Air Pollution Control Program regulations, which were adopted by

the Montana Board of Health and Environmental Sciences (MBHES) on

September 16, 1994. These rules include regulations regarding emergency

procedure, paving of roads, driveways, and parking lots, street

sweeping, National standards of performance for new stationary sources

(NSPS), National Emission Standards for Hazardous Air Pollutants

(NESHAPs), and solid fuel burning

[[Page 45113]]

devices. Further, EPA proposes that this submittal satisfies the one

remaining commitment made by the State in a previous PM10 SIP

submittal.

In the Final Rules Section of this Federal Register, EPA is acting

on 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 action 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be withdrawn before the effective date by publishing a subsequent

document that will withdraw the final action. All public comments

received will then be addressed in a subsequent final rule based on

this action serving as a proposed rule. EPA will not institute a second

comment period on this action. Any parties interested in commenting on

this document should do so at this time.

DATES: Comments on this proposed rule must be received in writing by

September 29, 1995.

ADDRESSES: Written comments on this action should be addressed to Amy

Platt, 8ART-AP, at the EPA Regional Office listed below. Copies of the

State's submittal 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
