EPA MAPS (Envision) can be used with IE 8 but there are some small limitations in the display when these versions are used. These browser versions were selected by looking at what the highest web browser usage types are on Envision and the Geoportal before we upgraded this website. We got this usage information from our Google Analytics reports.
