**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Proposed rule.
**SUMMARY:**
Environmental Protection Agency (EPA) proposes to approve the revisions to Oregon's State Implementation Plan which were submitted on November 20, 2000. These revisions consist of the 1996 carbon monoxide periodic year emissions inventory for Klamath Falls, Oregon and the Klamath Falls carbon monoxide maintenance plan. EPA also proposes to approve Oregon's request for redesignation of Klamath Falls from nonattainment to attainment for carbon monoxide.
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 and anticipates no adverse comments. 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If the EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 October 22, 2001.
**ADDRESSES:**
Written comments should be addressed to Connie Robinson, Office of Air Quality (OAQ-107), at the EPA Regional Office listed below.
