Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (twenty fifth update- December 1, 2008)‏

Damon:

I hope you also had a nice Thanksgiving time!

Thank you for the latest update on the petroleum cleanup in the Lake Formosa neighborhood.  It does sound like additional scope for cleanup will be required per the referenced issues. But considering the timeframe originally quoted (4 to 5 years), all seems within established requirements.

We have noticed the gas tank is gone now but the barricades are still there.  We appreciated your vigilance and support with regard to the safety of the neighborhood by placing those protective barriers around the gas tank. Traffic during peak hours means a lot of vehicles travel east on South Lake Formosa Drive, then sharply turn to the south up Philadelphia Avenue to access Virginia Drive.  The tank was a little close to that busy corner where these two streets come together. Thanks again for supporting our call for some minimal safety measures to protect the people living across the street from the tank, in the event a vehicle should ever run into the tank.

We look forward to continual status on the progress of this project.   Meanwhile, all the very best wishes for a very Happy Holiday to you and everyone!

Best regards,

Ms. Mills,

I hope you had a nice Thanksgiving holiday.  I would like to take this opportunity to give you our twenty-fifth monthly update on the project.

Report Status / General Status:

No reports are in house at the time and the next one is due December 31, 2008, but I am hoping to have it early from Argus.

We had a teleconference recently with Argus and discussed the specifics of how to address the lingering contamination seen at MW-5 and AW-10 with air sparging in this area. The use of air sparging wouldn’t require any additional equipment because the existing compressor would be used to supply the air to the air sparging wells similar to how the air was delivered to the sparge wells by the lake.

The area where soil contamination lingers is not far from where the underground storage tanks were at the former Sellers Auto and a review of soil assessment data over the years shows that there may be enough of a source there that additional assessment of this area is necessary before pilot testing air sparging for this area.  A change order to the existing work order, or a new work order will address this assessment.  Assessment will be done during daylight hours and will not result any excessive noise, odors or equipment.  Tentatively, it looks  like the assessment will include several soil samples to be taken from this area as well as the installation of up to three shallow monitoring wells.

After the assessment, it will take a several months to pilot test, design and construct the system modification to hone in on this area.  However, treatment of the existing system will not have to cease while any of this is done.  I believe we will still meet our original cleanup goal.

The system is currently running and the oxidizer remains off and onsite pending the approval of it’s use at a site in another county.  The propane we recently removed and the barriers will soon be moved, if they haven’t been already.

Milestone Update:

There is no new milestone update this month, but I think we’ll have one soon to share with you.  As soon as I have the data, I will share it with you via a short update like this one.  I look forward to giving you that as well as the next full update on January 2, 2009.  Please feel free to call me anytime if you need additional information or have any questions.

Thank you,
