1. 1 Gerald Gentleman Station Well Field Meeting April 26, 2004

2. 2 Welcome Thank you for coming! Beth Boesch Corporate Communications Manager Nebraska Public Power District

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

4. 4 NPPD’s Goals & Communication 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 Bill Fehrman President and CEO, Nebraska Public Power District

5. 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. 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. 7 Well Field Information & Effects Cooling Water Process Well Field Configuration Projected well field effects Groundwater monitoring Brian Barels Water Resources Manager, NPPD

8. 8

9. 9 Well Field Configuration Approximately 40 wells 2,000 gallons/minute 350-500 feet deep 30-40 year life Final well locations are under review

10. 10 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

13. 13 Groundwater Monitoring - Overview - Monitor effects of the GGS well field operation To update groundwater model for use as a predictive tool for mitigation

14. 14 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

15. 15 Twin Platte NRD Independent monitoring sites around GGS

16. 16 Project Status 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 John Cizek Senior Engineer/Project Manager, Gerald Gentleman Station

17. 17 Well Mitigation Process 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 Bill Fehrman NPPD President and CEO

18. 18 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/www.nppd.com/drought/ Call Center 1-877-ASK-NPPD
