## Abstract

EPA is finalizing approval of revisions to the Yolo-Solano Air Quality Management District (YSAQMD) portion of the California State Implementation Plan (SIP). These revisions were proposed in the Federal Register on February 1, 2006 and concern volatile organic compound (VOC) emissions from organic liquid storage and transfer facilities. We are approving YSAQMD Rule 2.21 that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
