  1. Using the Exchange NetworkOne State’s Perspective Deb Soule New Hampshire Department of Environmental Services NERACOOS/NECOSP Data Management Workshop, Sept. 26, 2012

  2. NHDES and the EPA Exchange Network • Exchange Network is becoming the main way to give data to the EPA, other states, and stakeholders • Currently “flow” 6 flows: • Air quality (AQS), Beach advisories, Facility (FRS) data, RCRA (Hazardous waste generators), SDWIS (Drinking water), WQX (water quality exchange) are the regulated flows • ODPX (Ocean Data Partnership Exchange) is non-regulated • Anticipate adding other flows (UIC, Assessment data) • Funding/reporting requirements often drive flows

  3. About our data • Data ranges across all divisions of the dept – air, waste, and water • Lots of monitoring data and regulatory data • Data updated according to program needs • Many programs have been collecting data for many years

  4. How we manage our data • Primarily use several relational databases (Oracle, FoxPro, or Access) some of which are linked but many are not • Metadata is a problem for us – particularly for our GIS data. No standard and no policy. Only have GCMD record for 1 database. This metadata was built after partnership workshop. • Can get some of our data from: • NHDES OneStop web site • EPA system web sites we contribute data to • Exchange Network • upon request

  5. Data Management Successes In terms of the Exchange Network… • With a few clicks of the mouse, able to create beach notification and WQX files, submit to the EPA, determine status, and update our internal databases with what data was sent. • We search for WQX data (using EPA WQX warehouse on-line form and now web services) from surrounding states to help in assessing waterbodies. Get data in a format we already know with adequate documentation, quickly, and with no cost.

  6. Data Management Challenges • Setting up flows takes a lot of time. • Flows change over time so continual updating needed. • Have to compete for limited IT resources – jury of your peers • Dept focus for next several years is to convert Oracle forms to .Net for many (30 +/-) databases. Very little new development anticipated. • Hardware constraints – no space or speed to run programs. Difficult to find test environments.

  7. Take home points • Standardization of data and ease to submit data (once flows are built) • Received a lot of money to set up these flows • Can take a lot of time to create the flows although things are getting easier (plug-ins) • Lots of security which is good and bad • Lot of data readily available from states/EPA web sites
