Ms. Mills,

I would like to take this opportunity to give you our Twentieth monthly update on the project.

Report Status:

There are currently no reports in house for the County to review, and Argus Consulting that the report due on July 1st will be submitted by Monday or Tuesday of next week. I had expected it would be a little early.

From conversations with Mr. Horton, and from data he submitted via E-Mail in June, we are still very close to turning off the oxidizer. However, we are not quite there and it will have to remain running a little longer. The latest air sampling data (in June) showed that the hydrocarbon concentrations were still a little too high for us to allow it to be turned off and discharged to atmosphere. Argus will sample the air stream again in about a week though and if we see that the levels have dropped to below the allowable threshold, the oxidizer can soon be turned off. In my last e-mail I estimated a mid-June turn off date, but I believe it will be late July to early August now. Incidentally, I received a call yesterday from a consultant that has asked to take the oxidizer to another site (in another county) as soon as we can authorize it to be turned off.

General System Status:

As noted above , the system has had some downtime mostly due to storm surges but seems to have had a pretty good run time as far as we can tell so far. Hour meter run times in the next report will allow us to know for sure what the run time had been for that reporting period. The latest storm surge damaged the phone line for the system telemetry but I believe it was repaired pretty quickly and didn’t result in very much downtime.

I don’t have very much of a technical update this time because there hasn’t been any major modifications to the system or a submittal of a report lately. The status summaries for each of the parts of the overall system remain basically the same this time.

Milestone Update:

I think the next milestone data will be available in August 2008. In the meantime, we will review the recommendations in Argus’ reports for system enhancements that may hasten the cleanup of MW-5, the most contaminated monitoring well left.

I look forward to giving you the next update on August 1, 2008 and if possible I will see if I can provide updated milestone data ahead of time. Please feel free to call me anytime if you need additional information.

Thank you,
