## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the Placer County Air Pollution Control District (PCAPCD) portion of the California State Implementation Plan (SIP). This revision concerns oxides of nitrogen (NO<INF>X</INF>) emissions from natural gas-fired water heaters, small boilers, and process heaters. We are approving a local rule that regulates these emission sources under the Clean Air Act (CAA or the Act).
