Air Plan Approval; California; Sacramento Metro Air Quality Management District
The Environmental Protection Agency (EPA) is proposing 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 proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
