nhdes and the epa exchange network
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
about our data
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
how we manage our data
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
data management successes
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.
data management challenges
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.
take home points
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
