INTRODUCTION

This appendix is presented in two major sections; section C1 provides laboratory test results and some analyses of the soils at the project site while section C2 provides similar types of presentations for the rock.

The information is temporally organized by investigation or O&M activity, each of which has the first page bookmarked. To assist the reader in spatially locating the borings, the last two pages of this appendix provide a table in which the boring identifications have been correlated to the sub-areas as shown on the ‘Overall BLP’ in Appendix B.
