National Environmental Information Exchange Network

The Environmental Information Exchange Network (EIEN) is an internet-based system used by state, tribal and territorial partners to securely share environmental and health information with one another and the U.S. Environmental Protection Agency (EPA).

EIEN partners share electronic data more easily and at a lower cost, and environmental decision makers are able to use the data to make timely decisions. These data include but are not limited to ambient air quality, air emissions inventory, inland water quality, coastal water quality, drinking water violations and National Pollutant Discharge Elimination System data.


  • improves the timeliness and accuracy of environmental data,
  • reduces the burden and costs associated with reporting data,
  • enhances data access for environmental professionals, and
  • supports better decisions on environmental and health issues.


The Exchange Network Grant Program provides funding to states, territories and federally recognized Indian tribes to support the development of the EIEN. The primary outcome expected from Exchange Network assistance agreements is improved access to, and exchange of, high-quality environmental data from public and private sector sources.
