Summary

EPA is proposing to approve a revision to the Yolo-Solano Air Quality Management District (YSAQMD) portion of the California State Implementation Plan (SIP). This revision concerns the District's demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). The EPA previously proposed to disapprove YSAQMD's 2006 RACT SIP submittal for the 1997 8-hour ozone NAAQS because we found that existing District rules implemented RACT for many but not all applicable sources. The YSAQMD has since addressed these deficiencies by adopting approvable rules that implement RACT and by adopting negative declarations where the District concluded it had no sources subject to RACT requirements. Therefore, we withdraw our previous proposed disapproval of YSAQMD's 2006 RACT SIP and now propose to approve it into the California SIP. The EPA is also proposing to approve YSAQMD's negative declarations into the SIP for the 1997 8-hour ozone NAAQS.

We are proposing to approve local SIP revisions under the Clean Air Act (CAA or Act). We are taking comments on this proposal and plan to follow with a final action.
