EPA facilities labels draw at scales greater than 2 million. This SEGS dataset was produced by EPA's Office of Environmental Information (OEI). This web service layer shows the boundaries of EPA regions based on 2011 TIGER/Line geometry. This layer is drawn at scales of 5,000,001 or less. This SEGS dataset was produced by EPA through the Office of Environmental Information (OEI).
