ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OR55-7270-b; FRL-6438-6]


Approval and Promulgation of State Implementation Plans: Oregon

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to approve the State Implementation Plan 
(SIP) revision submitted by the State of Oregon for the purpose of 
bringing the Lakeview, Oregon into attainment for the National Ambient 
Air Quality Standards for particulate matter with an aerodynamic 
diameter less than or equal to a nominal ten micrometers (PM10). The 
SIP revision was submitted by the State to satisfy Federal Clean Air 
Act requirements for moderate PM10 nonattainment areas.
    In the Final Rules Section of this Federal Register, the EPA is 
approving the State's SIP submittal 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 action, no 
further activity is contemplated. If the 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the direct final rule will be withdrawn and all public comments 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. Any parties 
interested in commenting on this action should do so at this time.

DATES: Written comments must be received in writing by October 21, 
1999.

ADDRESSES: Written comments should be addressed to Montel Livingston, 
Environmental Protection Specialist (OAQ-107), Office of Air Quality, 
at the EPA Regional Office listed below.
    Copies of the state submittal are available at the following 
addresses for inspection during normal business hours: Environmental 
Protection Agency, Region 10, Office of Air Quality, 1200 Sixth Avenue, 
Seattle, WA 98101; State of Oregon Department of Environmental Quality,
