Approval and Promulgation of Air Quality Implementation Plans; State of Washington; Yakima Carbon Monoxide Redesignation to Attainment and Designation of Areas for Air Quality Planning Purposes

Özet

On September 26, 2001, the State of Washington submitted a request to redesignate the Yakima "not classified" carbon monoxide (CO) nonattainment area to attainment for the CO National Ambient Air Quality Standard (NAAQS). The State also submitted a CO maintenance plan for Yakima. In this action, EPA is proposing to approve the Yakima CO redesignation request and the maintenance plan. In the Final Rules Section of this Federal Register, EPA is approving the State's redesignation request and State Implementation Plan (SIP) revision, involving the maintenance plan, as a direct final rule without prior proposal because the Agency views the redesignation and SIP revision as noncontroversial 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties in
