Abstract
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD), Eastern Kern Air Pollution Control District (EKAPCD), and Yolo-Solano Air Quality Management District (YSAQMD) portions of the California State Implementation Plan (SIP). These revisions concern emissions of oxides of nitrogen (NO<INF>X</INF>) from boilers, steam generating units, process heaters, and stationary internal combustion engines. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the ``Act'').
