## State/EPA Environmental Information Exchange Network – Overview 

- February 16, 2005
- XML Community of Practice (XML CoP)

## Exchange Network (EN) Core Components

- Nodes
- Hardware and software used to exchange information on the Network
- Transfer point on the Network
- Specially configured web-server
- Data Exchange Templates
- Describe format of data being exchanged
- Consist of  XML schema
_**Incorporate Data Standards**_
- XML Schema for flows found in the Registry

## Data Flowing on the Exchange Network

- Facility Data from States to EPA
- Water monitoring data between states and EPA
- Air emissions data between states (state to state) and to EPA (state to EPA)
- Waste data between states (state to state) and EPA (state to EPA)

## Example of leveraging ....

- A Quick Case Study.....leveraging data published (web service) on Node
- The Pacific Northwest Water Quality Exchange
- Washington Department of Ecology Partners with Oregon, Idaho, and Alaska to share water sampling results.
- Washington Dept of Health wants subset of that data related to fish tissue sampling.
- Reuse, Node and XML to easily provide this data

## Exchange Data Flow Model

- Later...

**Notes:**
Describe use of host database by non-node partners
Identify Data Access Tool for data discovery purposes
Describe STORET FUTURE availability on the Exchange and upload.

## 1.  Select Data Sources

- 2.  Go to Map

## Select a Region

## Coordinates Returned from map

- Choose More Parameters

- Fish Tissue Contamination and Birth Defects Assessment Application
- Leveraging information published for multiple purposes..how does WA DOH access and store WA DOE data...

## WA DOE and DOH...

- Version of WA DOE Node installed at DOH
- DOH allowed to use this to Query WA DOE Node for water sampling/fish tissue sampling projects and results published on the DOE Node
- DOH integrates this Node client (node that can call up the other Node with a simple command) into their application
- DOH can now query real time sampling from DOE and download into their application to look for trends.
- Illustration....

## DOH EIEIO Application – Screen Shot 1Query Results – List of Studies

- Query Button triggers Node client
- Request for fish tissue sampling data
- From WA Dept of Ecology

**DOH EIEIO Application – Screen Shot 2****Query Results**
**Date Range, Location, Taxon, Analyte**

- Can refine query search. Results brought back into database

**Notes:**
Query parameters – information that matters to the toxicologist.  -date range, taxon type, analyte, location.  

## What is the end result?

- 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
- 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!

## Reflections and Learning

- No longer dependent upon making sure systems can talk – web services are interoperable
- Provided 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.

## Other Exchanges Under Development – Partners are growing Fast!

- Pesticide-related illness surveillance data exchange
*California Environmental Protection Agency Office of Environmental Health Hazard Assessment and California Dept of Pesticide Regulation*
- Hazardous Materials data exchange
*California, Environmental Protection Agency’s Unified Program Office working with certified local agencies who have authority for some inspections*
- Biodiversity Data exchange
*Delaware Department of Natural Resources and Environmental Control (DNREC), Washington Department of Ecology, and NatureServe (non-profit)*
- Watershed Data exchange
*Kentucky, Governor’s Office for Technology, KY Dept of Environmental Protection, KY Office of Geographic Information, KY Commonwealth Office of Technology, USEPA Region IV, Open GIS Consortium*

## Other Exchanges Under Development

- Generic Homeland Security Exchange
*Michigan Department of Environmental Quality, Maine Department of Environmental Protection, New Jersey Department of Environmental Protection, New Hampshire Department of Environmental Services*
- Hydrographic Related Geospatial Data Exchange
*Minnesota Pollution Control Agency, Minnesota Department of Administration’s Land Management Information Center through the Minnesota Governor’s Council on Geographic Information Hydrographic Committee*
*Research and Metadata Exchange*
*University of Minnesota*

## Other Exchanges Under Development

- Air Monitoring Data Exchange
- New Jersey Department of Environmental Protection, New York Department of Environmental Conservation, Delaware Department of Natural Resources and Environmental Control
- Best Management Practice installation and implementation data exchange for the Chesapeake Bay
- Pennsylvania Department of Environmental Protection, Maryland Department of Environment, Maryland Department of Natural Resources, Maryland Department of Agriculture, Virginia Department of Environmental Quality, Virginia Department of Conservation and Recreation, USEPA Chesapeake Bay Program Office
- Ambient Air Quality Exchange
- Washington Department of Ecology (lead), pacific northwest states and tribes

## 2005 and Beyond....

- Many new partners and projects underway
- Suggestions for new data standards will most likely be found; open to adopting other standards already in place in other agencies.
- Looking at interoperability issues with other Networks
- More robust XML Registry or UDDI registry with validation routines is needed
