Air Quality Plan; California; San Diego County Air Pollution Control District; Landfill Flares

What it does

This revision concerns emissions of oxides of nitrogen (NO<INF>X</INF>) from landfill flares. We are proposing to conditionally approve a local rule to regulate these emission sources under the Clean Air Act (CAA or "Act"). We are taking comments on this proposal and plan to follow with a final action.
