  1. National Hydrography DatasetApplication Symposium Andrew T. Battin Senior Information Resource Management Official U.S. Environmental Protection Agency Office of Water December 11-14, 2000 The University of Texas at Austin

  2. Geo-Referencing History & Purpose • A Brief History of the Office of Water • Traditional permitted outfall / intake approach • Watershed emphasis • Recent Agency Emphases • Multi-media program implementation and oversight • Place-based initiatives • Information integration • Why Do We Need Geo-Referencing?

  3. OW Needs to Portray and Analyze DataGeographically ... Points - Monitoring site - Point source discharge - Drinking water supply - … Lines - Drainage network - 303(d) listed waters - Designated use waters - 305(b) waterbodies Polygons - Watersheds - Source Water Protection Areas - ...

  4. To Best Support Its Mission Needs • Easy Access from the Desktop and Through the Internet • Enabling Simple Queries to Complex Analyses of OW & Other Data Resources to Support: • Public Right-To-Know • TMDLs • Water Quality Standards • Source Water Protection Areas • Water Treatment Construction Needs • Permits • Clean Water Action Plan • Unified Watershed Assessments • GPRA • Consolidated Reporting • Drinking Water Intakes • ... Surface Waters Land Use Demography Habitat States/Counties ...

  5. How Does NHD SupportWater Programs? • Geo-Referencing of Water Program Information • EPA & Public Use of Geo-Referenced Water Information to Support Program Implementation and Oversight • Systems Integration using the Geo-Referencing Framework

  6. Water Quality Standards Total Maximum Daily Loads Combined Sewer Overflows Sanitary Sewer Outfalls Tribal Boundaries & Facilities Drinking Water Intakes Source Water Protection Areas Sediments Nutrients Stormwater Drains Beaches Fish Advisories STORET Monitoring Water Program Priorities for Geo-Referencing

  7. EPA & Public Use of Geo-Referenced Water Information • Enable simple queries • Locate all permitted facilities on a river section • Modeling and other complex analyses • Calculate TMDL for a river section • Static & Dynamic Maps and Database Access Surface Waters Land Use Demography Habitat States/Counties ...

  9. The NHD Framework and Other EPA Initiatives • Reinventing Environmental Information (REI) Data Standards • Locational Data Improvement Project (LDIP) • EPA’s Information Integration Initiative (I3)

  10. Reinventing Environmental Information Data Standards • Facility Identification Data Standard • Latitude/Longitude Data Standard • Point location/documentation • Geo-Locational Data Standard • Under “development” • To support linear and polygon features NEW!

  11. Locational Data Improvement Project (LDIP) • Gather existing latitude/longitude point coordinates (with metadata) • Encourage High Quality, Well-Documented Future Collections • High Quality Coordinates critical for Geo-Referencing Activities

  12. IV. EPA’s Information Integration Initiative (I3) • Demonstrating Integration through Geography – “Window to my Environment” • Geo-referencing framework supports place-based integration of information

  13. Summary • Geo-Referencing of Water Program information • Query / Modeling Capabilities • Databases Access and Maps can be Dynamic • Systems Integration using the Geo-Referencing Framework • Data Standards are in place and new standards are under development • Geo-Referencing supports the Agency goal of placed-based integration of information
