Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 update #59)‏

October 3, 2011

Ms. Mills,

I would like to take this opportunity to give you our fifty-ninth monthly update on the project.   The good news is that at the end of the last quarterly period the system was turned off and, as long as the site is clean for the second consecutive quarter, the system will remain off.   I will follow up with you in a couple of weeks to confirm this after we get the data back from the late September groundwater sampling event.   If the system remains off, I propose changing the frequency of these updates to quarterly to coincide with the quarterly Post Active Remediation Monitoring reports. 

 Report Status

The next report of active operation and maintenance should be the final one and it is due on October 31, 2011.   AS stated in the last update, if the results of the late September groundwater sampling show a rebound, we may have to restart the system after that.  However, I am optimistic that we won’t have to do that.   After this report that is due in October, we plan on beginning quarterly sampling.   A minimum of four quarters of sampling is required by Chapter 62-770 and a Site Closure is able to be considered if the last two results are below cleanup target levels.

 

System Status:

There is no new information regarding the system status other than it is off.   After we begin quarterly monitoring, the consultant will be tasked with mothballing the system to prevent deterioration from lack of use while it remains on site in case of a rebound in groundwater concentrations.  In the beginning of the third quarter of groundwater sampling, it may be put on the FDEP’s list of sites that are available for transfer to another site.  Although it won’t be running, (assuming there is no need to turn it back on) the system will probably remain there for a full year longer.

Milestone Update:      

As stated in last month’s update, all of the wells sampled in the comprehensive annual sampling event at the end of June are below Groundwater Cleanup Target Levels (GCTL).    We will need to watch AW-28, DW-11 and MW-9 in the next sampling event to verify these wells do not rebound since these have only showed to be below target levels one time.   Wells AW-10 and MW-5 will also need to be checked.  Assuming the results of the late September sampling show every well to remain below target levels, the system will be turned off and the one year or Post Active Remediation Monitoring (PARM) will begin.

I will send you a very brief update on or before October 17, 2011.    Please feel free to call me anytime if you need additional information or have any questions.

Thank you,

Damon Taylor
