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 FehrmanPresident and CEO, Nebraska Public Power District

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

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

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

Groundwater Monitoring- Overview -

Monitor effects of the GGS well field operation

To update groundwater model for use as a predictive tool for mitigation

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

Twin Platte NRD Independent monitoring sites around GGS

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 CizekSenior Engineer/Project Manager, Gerald Gentleman Station

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 FehrmanNPPD President and CEO
