## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Placer County Air Pollution Control District (PCAPCD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of oxides of nitrogen (NO<INF>X</INF>) and particulate matter (PM) from open burning. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
