Lockridge Remediation Site

Larry-
Remediation efforts to remove PSH have gone well recently and it is now time
to focus more attention toward remediation of the dissolved phase plume. This
is reflected in the proposed scope.

Two files are attached. The first file includes a project scope and cost
estimate for 2001. The second file contains photos of the site.

The cost estimate is $93,000. This figure includes only contract installation
dollars, so the work order amount would be about 20-30% more than this. The
bulk of this figure ($53,000) is for system modifications to focus more
attention toward remediation of the dissolved phase plume.

If you get a chance to look at the photos, be sure to look at the last photo.
This photo shows the interior of the SVE knockout box that was installed in
Dec 1999 in the NE pit area. This installation has worked very well over the
past two winter periods and has greatly increased the effectiveness of the
SVE system. The SVE knockout box recently installed at the N Crawar site is
nearly identical.

Give me a call and lets discuss.
