Provide a map showing the locations of the groundwater users listed in Tables 2.4-8, 2.4-9 and 2.4-10.

3.

Provide a summary of legal restrictions relating to water use imposed by State or Federal regulations.

4.

Discuss the erosion and transport mechanisms applicable to surface-water bodies in the site area.

5.

Provide the velocity distribution and flow characte-istics at or near the intake and drainage structures.

6.

Discuss the interaction of groundwater and surface. ter in the site area,-including points at which groundwater discharges into streams.

7.

Discuss the historical and seasonal trends in aquifer water levels.

8.

Provide a water use diagram and a narative showing and discussing the flow rat.es to and from the various systems, including heat dissipation, service water and other systems.
