Abstract
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Sacramento Metropolitan Air Quality Management District (SMAQMD) portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NO<INF>X</INF>) from water heaters, boilers, and process heaters. We are approving a local rule that regulates these emission sources under the Clean Air Act (CAA or the Act).
