## Abstract

EPA is taking direct final action to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD) portion of the California State Implementation Plan (SIP). These revisions concern volatile organic compound (VOC) emissions from leaking components at facilities such as oil refineries and chemical manufacturing plants. We are approving a local rule that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act). At the same time, we are also approving an AVAQMD Negative Declaration and removing rules from the SIP.
