									  Exchange Network – Why
    Should I participate???
Whad’ya Node? Exchange Network Node Mentoring
                   Workshop

            Presented by Molly O’Neill

            New Orleans, Louisiana
           February 28-March 1, 2005



                                                1
History
• In the past, States had to report data to EPA in
  many different formats for each regulatory
  program
   –   Resource double data entry
   –   Maintenance of interfaces
   –   Tracking changes that EPA made to databases
   –   Staff might need expertise in many different code
       languages simply for the exchange processes alone
• EPA national data systems and state data
  systems not in sync
   – Huge problem when the press queries a national
     database and lists issues with State (e.g., not
     following up on an issue) that might not be true


                                                           2
History
• In frustration, some states refused to
  report to national systems or had EPA
  Regional offices do the work
  – Data gaps now present
• Existing and old exchange mechanisms
  compromised the data quality

     Staff (data users) may spend up to 50% of
     their time looking for data – access is
     limited for all the reasons stated
     previously

                                                 3
History of the EN
• 2000 Blueprint and 2002 Implementation
  Plan provides the conceptual design of
  the Exchange Network and initial focus
  areas
• Focus was on Type 1 flows with an
  understanding that other types of flows
  could also be supported in the future
  – Type 1 flows were the State to EPA data
    flows




                                              4
Early implementation findings
• Other Federal Agencies adopting the
  same EN core concepts of utilizing web
  services and XML language
  – Homeland Security, Dept of Justice,
    Department of Defense, Dept of Health and
    Human Resources
  – Initial technology decisions were the correct
    ones
  – This means, sharing data across
    agency/department boundaries will/should
    be much easier


                                                    5
Early implementation Findings
• The concepts of the EN can be
  distributed and used
  eBusiness/eGoverment
  – Michigan DEQ demonstrates this with their
    eDMR/eDWR data flow from industry to
    state databases to federal databases
    automatically
     • Cost savings being documented and
       captured for both the state and industry
       are a great story (Associated Press
       article written)


                                                  6
Paradigm Shift
• Publishing data on the Node provides
  unparalleled access to data
  – Data owner can control access to secure
    area where data is published
  – Owner can provide continuous real time
    data to data consumers or users




                                              7
Benefits and Examples
• Real time and better access to data
  – Pacific Northwest Water Quality Exchange
  – Linkages between Health and
    Environmental Data

 Benefits

• Using the Exchange Network……
  – Much better quality data being exchange
     • Data Standards embedded in XML Schema
     • Closely working with State/EPA Data Standards
       Council for new standard adoptions to
       incorporate
     • Machine to machine – no human data entry
       mistakes
     • Schematron verifies business rules for exchange
       – more validation
  – More data can be exchanged among new partners
     • Infrastructure can be applied to new data
       exchange types
     • New State to state exchanges already occurring
  – More timely data
     • Data can be published and exchanged as soon
       as partners agree. Machines do the work!          14
Reflections and Learning
• No longer dependent upon making sure
  systems can talk – web services are
  interoperable
• Provides an infrastructure and
  mechanism to support new data flows
  between existing and new partners!
• Publishing data in a secure place on the
  Exchange Network has proven far easier
  and sets a new paradigm for future data
  exchanges
