The Environmental Protection Agency (EPA) has developed a mapping tool that organizes Environmental Impact Statements (EIS) prepared by federal agencies, as well as EPA’s comments concerning the EIS’s. The National Environmental Policy Act requires federal agencies proposing projects or making decisions on major federal actions to develop an EIS. Within the database, one can search by year, by state, or by EIS’s with open comment records since 2004. EPA comment letters issued within the last 60 days are also available on the map.
