I would like to take this opportunity to give you our thirty-seventh monthly update on the project.
The general status is pretty much the same this month as it was last month. The system is still running with a selected set of treatment points. I now have two reports to review before Argus can submit the Remedial Action Plan. I intend to rush these reviews and am going to work closely with David Jones, P.E. to expedite the review as well. I’m unsure if we’ll have our review letter to Argus in time for the January e-mail update, but if it is beyond that, it won’t be much beyond it. There is still no need to cease operation of the system while this occurs because contaminant mass continues to be removed from the subsurface.
The cleanup goal is a four-year active phase remediation term plus an additional year of post active monitoring. We are striving to finish early and not have the system run for the full four years. I believe the use of air sparging/soil vapor extraction in front of the former Sellers Auto will allow that to happen. The tentative date that we would expect to be finished with active remediation is January or February 2011, and completing post active remediation monitoring shortly after February 2012. Again, we will continue to strive to beat these deadlines.
The system runtime during this quarter was less than the required 80% again with the major cause of downtime attributed to the system being shut down due to the significant rains during this period. This report (covering May 28th through August 22nd) is very similar to the last one. Argus states that beginning in April 2009, rainfalls have been very high. A chart in the report illustrates how much more rain than average has been seen in 2009. The graph seems to show it tapering off beginning in August, though still about 2 inches more rainfall than average. We can expect better efficiency from the infiltration gallery now though as we are into the dryer season.
The Year 3, Quarter 2 Operation & Maintenance Report received October 28th and the pilot test report received on November 2nd are being reviewed now. The next report I will receive from Argus is the Year 3, Quarter 3 Operation & Maintenance Report, which is due on December 31, 2009, but we expect Argus will be able to submit this one earlier.
The Remedial Action Plan Modification is due December 30, 2009.
The most recent groundwater sampling data is from August 28, 2009, which was discussed in October update. Argus recently performed groundwater sampling but the data isn’t available yet. I will share that data with you when it is available.
I will send the next update on January 4, 2010. Please feel free to call me anytime if you need additional information or have any questions.
