ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OR-11-1-5527b; FRL -4892-1]

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). The

implementation plan was submitted by the state to satisfy certain

Federal requirements for an approvable moderate nonattainment area PM-

10 SIP for La Grande, Oregon. 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

that direct final rule, no further activity is contemplated in relation

to this proposed 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final rule will be withdrawn and all public comments received will be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. The

EPA will not institute a second comment period on this notice.

DATES: Comments must be received by August 1, 1994.

ADDRESSES: Written comments should be addressed to: Montel Livingston,

EPA, 1200 6th Avenue, AT-082, Seattle, Washington 98101.

Documents which are incorporated by reference are available for

public inspection at the Air and Radiation Docket and Information
