## Abstract

EPA is taking direct final action to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD) and Imperial County Air Pollution Control District (ICAPCD) portions of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NO<INF>X</INF>) emissions from stationary gas turbines. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
