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

reducing the National Air Quality Standards (NAAQS) for carbon monoxide

(CO). The SIP revision was submitted by the State to satisfy certain

Federal Clean Air Act requirements for a basic motor vehicle inspection

and maintenance (I/M) program in the Portland Metropolitan Service

district and the Medford-Ashland Air Quality Maintenance Area. In the

final rules section of this Federal Register, the 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 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comments, the direct final rule will be withdrawn and all public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

on this document.

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

October 11, 1994..

ADDRESSES: Written comments should be addressed toMontel Livingston,

Environmental Protection Specialist (AT-082), Air Programs Section, 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.
