EPA has issued a new online mapping tool, NEPAssist, to assist federal agencies in evaluating possible NEPA environmental review obligations. NEPAssist is one of five pilot projects selected by the White House Council on Environmental Quality to advance the NEPA process through innovation, public participation and transparency.

NEPAssist is a tool that facilitates the environmental review process and project planning in relation to environmental considerations. The web-based application draws environmental data dynamically from EPA's Geographic Information System databases and web services and provides immediate screening of environmental assessment indicators for a user-defined area of interest. These features contribute to a streamlined review process that potentially raises important environmental issues at the earliest stages of project development.

Federal agencies can enter an address, zip code, city, county, watershed or a pair of coordinates in order to evaluate a potential new study area. The mapping tool also is available to the public at http://www.epa.gov/compliance/nepa/nepassist-mapping.html.
