          - 40 CFR Part 52 
          - [OR-77-7292-b; FRL-6583-1] 

# 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 revising the RACT Rule. The SIP revision was submitted by the State to satisfy certain Federal Clean Air Act requirements for a SIP. 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 If the EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

Written comments must be received in writing by June 9, 2000.
