Approval and Promulgation of Air Quality Implementation Plans; La Grande, OR; PM10 Maintenance Plan and Redesignation Request; Withdrawal of Direct Final Rule

Due to an adverse comment, EPA is withdrawing the March 22, 2006 direct final rule (see 71 FR 14393) to approve a PM<INF>10</INF> State Implementation Plan (SIP) maintenance plan revision for the La Grande, Oregon nonattainment area and to redesignate the area from nonattattainment to attainment for PM<INF>10</INF>. In the March 22, 2006 direct final rule, we stated that if we received adverse comments by April 21, 2006, the direct final rule would be withdrawn and would not take effect. EPA subsequently received adverse comment on that direct final rule. EPA will address all comments received in a subsequent final action based upon the proposed action also published on March 22, 2006 (see 71 FR 14438). EPA will not institute a second comment period on this document.
