What the agency says

The Environmental Protection Agency (EPA) is proposing to conditionally approve a revision to the San Diego County Air Pollution Control District (SDCAPCD or "District") portion of the California state implementation plan (SIP). 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.
