Geologic & Geotechnical SiteCharacterization Scope

" Perform geological, geotechnical and geophysical exploration program to

confirm and refine:

" site stratigraphy and groundwater conditions" static and dynamic soil and rock properties" site geohazards and foundation conditions

" Evaluate variability of site conditions and soil and rock parameters

" Evaluate site suitability with respect to regulatory guidance and reactor

vendor DCD

" Update, as required, site soil profile, site response, and SSE

* Characterize possible seismic and/or geotechnical hazards and evaluate

mitigating measures

Geotechnical Borehole Procedure" Work Instructions issued to drilling companies and Rig Geologists defining duties

" Boring Assignments for each borehole prepared by MACTEC Site Coordinator

with Principal (WLA/MACTEC) review; Boring assignments specify:

* Boring location and Type* Boring depth and required testing* Boring Completion

" TVA personnel review drill site and provide excavation permit

" Rig Geologist directs Drill Crew to prepare drill site and instructs drill crew to

prepare and perform as per Boring Assignment

" Rig Geologist monitors drilling, describes samples, maintains field log

" Modifications to Boring Assignment instructions, if needed, reviewed and approved

by Site Coordinator

" Samples transported to site storage facility at end of day

Monitoring Wells Installation Procedure

" Hydrology Lead directs boring layout using GPS methods

" TVA personnel provide clearance for drilling

" Site Coordinator prepares Boring Assignment for lithologic boring and gives to Rig

Geologist

" Rig Geologist and drill crew executes the Boring Assignment using procedures referenced

in Work Plan, logging boring and submitting samples and cores for on-site storage

" Hydrology Lead reviews boring logs for well design and provides well construction plan to

Site Coordinator

" Site Coordinator prepares Boring Assignment for monitoring well installation and gives to

well crew and Enercon observer

" Drill crew installs under Enercon observation
