Summary of Klamath Falls Carbon Monoxide (CO) Maintenance Plan

Background

Klamath Falls, Oregon, was designated a nonattainment area for carbon monoxide (CO) and classified as moderate on January 6, 1992.

Oregon submitted a CO maintenance plan on November 20, 2000, which EPA approved on September 20, 2001 (66 FR 48349 (PDF)(7 pp, 153 K, About PDF)).

On November 5, 1999, Oregon submitted a complete rule renumbering and relabeling package to EPA for approval in the SIP.
