ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OR-61-7276; FRL -6307-6]


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 about the 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 (PM-10). This SIP 
revision was submitted by the State to satisfy certain Federal Clean 
Air Act requirements for an approvable moderate nonattainment area PM-
10 SIP for the Oakridge, Oregon, PM-10 nonattainment area. 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 submittal 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 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rule will be withdrawn and all public comments received will be 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. The 
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 April 14, 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. The interested persons wanting to examine these 
documents should make an appointment with the appropriate office at 
least 24 hours before the visiting day.
