National Environmental Information Exchange NetworkPotential for Regional LAEsBy: Dave Tetta and Andrew BattinUS EPA

what is the exchange network
What is the Exchange Network?
  • A partnership to support better environmental decisions through improved access to, and exchange of, improved environmental information
  • Tools and services that help environmental agency staff integrate, analyze and report data
  • Data and Technology Standards that allow for data to be integrated regardless of the technology
  • More efficient business operations that improves data quality and timeliness
  • Secure data exchanges over the Internet

how does the en accomplish this
How Does the EN Accomplish This?
  • Collaboration
    • Between EPA and its state, tribal, and territorial partners
    • Between agencies within states
    • Between offices within agencies
  • Technology
  • Shared tools and services
  • Grant Program
    • FY 2002 to present
    • $130M+ in grants to develop infrastructure and flow data
how does it work
How Does it Work?
  • Most Partners have a node
  • A node is a web (Internet) server that responds to requests for information
    • Requests and responses use common formats written is eXtensible Markup Language (XML)
    • Point of Presence through which partners exchange data
  • Nodes use standardized tools and technology neutral components
  • CDX is EPA’s node on the Exchange Network
  • Some partners use node clients
    • Software that is loaded on a desktop computer
    • Limited capabilities
    • Users can submit and request data
    • Does not respond to requests
    • Not automated
    • Less costly and easier to deploy
