  3. Meeting Agenda • NPPD goals • Communications • Well field information & effects • Monitoring plan • Project status • Well mitigation process • Current Follow-up Actions • Questions

  4. NPPD’s Goals & Communication Bill Fehrman President and CEO, Nebraska Public Power District • Ensure adequate water levels are in Sutherland Reservoir for GGS operation • Help GGS comply with discharge water temperature limits • Maintain long-term viability of the Ogallala Aquifer

  5. NPPD’s Goals & Communication (cont.) • Identify and mitigate potential effects to neighboring wells before they create adverse impact • Enforce NPPD’s approved Board Resolution • Provide for communication and feedback

  6. Communications • Local committee • Neighboring well owners/producers • Twin Platte NRD • Jim Goeke, Research Hydrogeologist, UNL • NPPD • Web-based Sutherland Reservoir elevation data • Web-based project status updates

  7. Well Field Information & Effects Brian Barels Water Resources Manager, NPPD • Cooling Water Process • Well Field Configuration • Projected well field effects • Groundwater monitoring

  8. Well Field Configuration • Approximately 40 wells • 2,000 gallons/minute • 350-500 feet deep • 30-40 year life • Final well locations are under review

  9. Projected Well Field Effects • Some water table drawdown outside of GGS property boundary field is expected • Pumped water will not be released to the downstream canal system other than through normal seepage/leakage • No influence on Republican River system • Low net consumption of water over time

  10. Groundwater Monitoring- Overview - • Monitor effects of the GGS well field operation • To update groundwater model for use as a predictive tool for mitigation

  11. Groundwater Monitoring Process • Bi-annual Independent monitoring by Twin Platte NRD • Thirty (30) existing non-NPPD wells near Sutherland Reservoir • Continuous monitoring of GGS wells • Additional NPPD monitoring of some wells off NPPD property • Data collected will be available to the public

  12. Twin Platte NRD Independent monitoring sites around GGS

  13. Project Status John Cizek Senior Engineer/Project Manager, Gerald Gentleman Station • Well field installation contract to Henkle Drilling and Supply • NPPD staff and Hemenway Groundwater Engineering providing construction management • Mobilization April 19; drilling April 25 • Wells installed, tested and registered by July 1 • Installation of pumps, piping and power source will continue through Fall, 2004

  14. Well Mitigation Process Bill Fehrman NPPD President and CEO • Board Resolution • NPPD will proactively identify and mitigate potential effects of the GGS well field on neighboring wells before these effects create adverse impact • Neighboring well owners can also contact NPPD to initiate the mitigation process • Challenge is identification of well problem causes

  15. Current Follow-up Actions • Reviewing well locations • Providing Sutherland Reservoir elevation data • Developing off property monitoring • Working with local committee • Continuing to take your comments • Web site www.nppd.com/drought/ • Call Center 1-877-ASK-NPPD
