Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (special update – update #57)‏

Damon:
It doesn’t seem possible it has already been 57 months since project start, but here we are today and the project is almost complete.
If the wells cited do not rebound, it sounds like project will be completed by end of this calendar year.
Thank you for keeping us well-posted on the results. This is awesome news!

Subject: Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (special update – update #57)

July 27, 2011

Ms. Mills,

I would like to take this opportunity to give you our fifty-seventh monthly update on the project.     I will follow up with a more thorough update later, but this one is just a brief one to let you know that we have finally reached cleanup target levels for every monitoring well sampled at the end of June, 2011.

Report Status

The Year Four Quarter Four report is due on August 12, 2011 (this date was extended from a July due date).  This one will include a milestone evaluation and a professional recommendation for the next course of action.   We are funded to run the system an additional three months to make sure that there is not a rebound in concentrations.  I think we may be able to turn the system off and enter Post Active Monitoring by sometime in September 2011.  I’ll follow up in the August update with more detail on this.

Milestone Update:

All of the wells sampled in the comprehensive annual sampling event at the end of June:  AW-2, AW-5A, AW-6R, AW-10, AW-15, AW-18, AW-22, AW-24, AW-26, AW-27, AW-28, AW-30, DW-11, MW-5 and MW-9 are below Groundwater Cleanup Target Levels.   Attached is a PDF table of the lab results that I received today.

From the above wells I note that AW-28, DW-11 and MW-9 each had concentrations above cleanup target levels at the end of March and this is the first quarter that these three wells are clean.    In the next sampling event we’ll need to see that these remain below cleanup levels for a second quarter.  We’ll also need to see that AW-10 and MW-5 do not rebound.   However, the late June sampling event is the second consecutive clean quarter for these two wells.

I am out of the office July 28th through August 1st, but I will return on Tuesday August 2nd.  I will follow up with an update very soon after August 2nd with more details.  Please feel free to call me anytime if you need additional information or have any questions.

Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (Update # 56)‏

July 1, 2011

Ms. Mills,

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

General Status:

There have not been any major changes with the operational strategy or sampling plan for the site in several months.  Yesterday, Argus performed the annual sampling event.  I expect in two weeks, we will have new groundwater data to share.  The next report is the annual one, which is due on July 12, 2011.

A professional recommendation to turn the system off and enter monitoring or to continue to operate the system for another quarterly period will be in this report.

System Runtime & Performance:

We have received no notices of downtime lately.   All air sparging wells are showing high flow rates as designed.  Three of the multiphase treatment well network of 26 (originally 24) are turned off.  In other words, there are only 23 vapor recovery wells being used to capture vapors.   Only the ones in the area of the contamination are being used to recover groundwater.   The target area is still the isolated area around monitoring wells MW-5, AW-10 & AW-28.   Surprisingly, with the heavy rain events we have been getting the infiltration gallery has continued to perform well.

Report Status

As stated above, the Year Four Quarter Four report is due on July 12, 2011.  This one will include a milestone evaluation and a professional recommendation for the next course of action.   I recently created a new work order to run the system for 90 days after this period, just in case it is needed.  However, it is possible this report may have a recommendation to turn the system off.

Milestone Update:

There isn’t a new milestone evaluation for this update.  In the past one, we had all wells having met milestones for the first time.   The site showed the lowest levels of contamination yet at that time – the groundwater sampling event of March 2011.

I will not be able to submit the update on August 1st because I will be out of town, but I will send it on August 2nd 2011.  However, I will likely contact you in the middle of the month with the new data before the monthly report.

I hope you have a great Fourth of July weekend.  Please feel free to call me anytime if you need additional information or have any questions.

Thank you,

Ms. Mills,

I would like to take this opportunity to give you our fifty-fifth monthly update on the project.     I’m sending this update a day early because I will be in training (unavailable by e-mail) on Wednesday June 1st.

General Status:

There have not been any major changes with the operational strategy or sampling plan for the site since the last update.   Nor have there been any periods of down time or reported operational problems.   The last time the groundwater was sampled was in mid March, so the next time we should have data would be sometime after mid June.   Therefore, we should have new groundwater data for you in the next update as long as I am able to get it ahead of the next report, which is due on July 12, 2011.   This report will be a significant one because it’s an annual report, which is to summarize the fourth year of operation.    A professional recommendation to turn the system off and enter monitoring or to continue to operate the system for another quarterly period will be in this report.

System Runtime & Performance:

We have received no notices of downtime lately.   All air sparging wells are showing high flow rates as designed.  Three of the multiphase treatment well network of 26 (originally 24) are turned off.  In other words, there are only 23 vapor recovery wells being used to capture vapors.   Only the ones in the area of the contamination are being used to recover groundwater.   The target area is still the isolated area around monitoring wells MW-5, AW-10 & AW-28.   In the last update, I mentioned that the spare soil vapor extraction blowers still wasn’t fixed, but this was fixed since the last update.  Now, the other soil vapor extraction blower needs some maintenance.  I am not sure if the other one is operable, but if it isn’t, we again have two soil vapor extraction blowers, of which only one is operable.   This hasn’t affected run time or efficiency though.  The goal is to rotate between the two of them periodically to ensure reliability.

Even with the occasional heavy rains, the infiltration gallery has continued to perform well.

Report Status

As stated above, the Year Four Quarter Four report is due on July 12, 2011.  This one will include a milestone evaluation and a professional recommendation for the next course of action.   I recently created a new work order to run the system for 90 days after this period, just in case it is needed.  However, it is possible this report may have a recommendation to turn the system off.

Monthly update for Sellers Auto / Artist Studio petroleum cleanup site 489201547 / 489201548 (Update # 54)‏

May 2, 2011

Ms. Mills,

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

General Status:

I am currently reviewing the year four quarter three report and it contains the data and updated milestones (see below for milestone summary).  The run time has been good and there hasn’t been any down time notices lately.  An expanded evaluation of the milestone data from last update is included here.  

System Runtime & Performance:

The run time has been pretty good.   All of the air sparging wells is showing good flow to the subsurface as designed.  Three of the multiphase treatment well network of 26 (originally 24) are turned off.  In other words there are only 23 vapor recovery wells being used to capture vapors.   Only the ones in the area of the contamination are being used to recover groundwater.   The target area is still the isolated area around monitoring wells MW-5, AW-10 & AW-28.  The soil vapor extraction blowers (the spare) problem I reported on last month still hasn’t been fixed.  We have two soil vapor extraction blowers, of which only one is operable.   This hasn’t affected run time or efficiency though since of them is a spare and the intent is to rotate periodically between them.    There still hasn’t been any shutdowns or problems caused by the infiltration gallery getting overwhelmed from heavy rain events.

Report Status

I am currently reviewing the Year Four Quarter Three report (received 04/12/11).   The next report is the Year Four Quarter Four (the annual report) and is due on July 12, 2011.  A milestone evaluation from this report is summarized below.

 Milestone Update:

For the first time, all wells have met milestones.  The site has the lowest amount of contamination to date, with only minor concentrations in two wells. 

·       AW-10 – This well is completely below groundwater target levels for the first time. 

            Benzene –not detected March 17, 2011 (8.1 ug/L November 4, 2010)

            Ethyl benzene not detected March 17, 2011 (145 ug/L November 4, 2010)

            Total Xylenes not detected March 17, 2011 (147 ug/L November 4, 2010)

            Naphthalene not detected March 17, 2011 (23.4 ug/L November 4, 2010)

·       AW-28 This well is almost below groundwater target levels for the first time.  The only detected contaminants above target level are Benzene and Total Xylenes, each of which are only one part per billion above the state prescribed groundwater cleanup level:

Benzene –1.2 ug/L March 17, 2011 (91.3 ug/L November 4, 2010)

            Ethyl benzene (11.0 ug/L) detected but below cleanup levels March 17, 2011,(565 ug/L November 4, 2010)

            Total Xylenes 21.1 ug/L March 17, 2011 (351.9 ug/L November 4, 2010)

            Naphthalene (1.2 ug/L) detected but below cleanup levels March 17, 2011, (48.4 ug/L November 4, 2010)

·       MW-5 – This well is also completely below and shows most dramatic reduction of all the wells.

           Benzene –not detected March 17, 2011 (89.8 ug/L November 4, 2010)

            Ethyl benzene not detected March 17, 2011 (525 ug/L November 4, 2010)

            Total Xylenes not detected March 17, 2011 (577 ug/L November 4, 2010)

            Naphthalene not detected March 17, 2011 (82.8 ug/L November 4, 2010)

Other wells that were sampled on March 17, 2011 include AW-26, AW-27, and DW-11.  The only detected contaminant in any of these three wells is Benzene was found in DW-11 at a concentration of 15.9 ug/L.  This well has fluctuated from below cleanup levels to 25.1 ug/L over the course of the cleanup.   This well and several others will be sampled in the upcoming comprehensive annual sampling event.  This data will be available sometime around early July.

I suspect that once the results come back for the early summer sampling event (sometime in June) we may approve a recommendation to turn the system off for good. 

I look forward to sending the next update on June 1, 2011.  Please feel free to call me anytime if you need additional information or have any questions.

November 1, 2010

 

Ms. Mills,

 

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

 

General Status:

The system has been running and will continue to run while the modifications are performed.  However, the system is being turned off now pending the portion of the upgrade which will require it to be off.  I expect it will remain off for at least a few weeks.

 

System Runtime & Performance:

 

There hasn’t been any significant down time in a while except for one at the beginning of the past week for a high water alarm.

 

Report Status

 

The next report is the Year Four Quarter Two which is due on November 22, 2010.   In the past update I stated that I thought this report would span a period of time before and after the improvements are made.  I don’t believe that will be the case, because the construction has not yet begun.

 

Milestone Update:

There is no new milestone data update this month since the last one that included the data collected in July.   The next set of groundwater sampling data will be available in a few weeks.  They just performed it over this past weekend.  I will provide the new data as soon as I get it from the consultant.

I will have further news on the construction status in the next update on December 1st .  Please feel free to call me anytime if you need additional information or have any questions.

 

Thank you,

Damon,

Without a figure, it’s impossible to know which additional well location you are talking about in item 1b.

I assume it is a supplemental well to handle the point source plume that remains beneath the building corner.

Since this point source seems to be one of the biggest remaining issues with the cleanup effort, the neighbors would be interested in learning how the contractor proposes to resolve this and a figure would be very helpful to understanding this.

Please send us a figure depicting the location of this additional well if one is available in PDF, JPG or TIFF format.

Thanks again for the transparency of your process and for keeping us informed on the details of this project.

Hello Robert,

I just wanted to let you know you can expect the RAP Approval is forthcoming. 489201547 – Sellers Auto Artist Studio RAPM R2C – 041510. The PE sealed letter will make it official when David gets back in a couple of weeks, but this is the final version of the letter so we don’t have to wait for that to get started on the Construction Drawings.

Please send a VCO to add construction drawings to our open O&M work order and choose an ambitious, but realistic due date for submittal of the drawings. If you have any questions, please don’t hesitate to give me a call. Thanks.

May 3, 2010

Ms. Mills,
I would like to take this opportunity to give you our forty-second monthly update on the project.

General Status:
The system was off for a while due to no work order being in place to fund it, but that has been resolved and the system was re-started last week.

The implementation of a Remedial Action Plan Modification is critical to meeting the cleanup deadline of being able to turn off the system in February 2011 to begin the one year monitoring phase. I am including a map this time that shows the entire monitoring well and treatment well network along with a blow up of the area where the contamination persists.

System Runtime:
Notwithstanding the time where there wasn’t a work order, the system runtime has been pretty good since October, greater than the required 80%, thus in compliance with the Remedial Action Initiative requirements.

System Performance:
The cumulative gallons of groundwater processed is about 18.4 million gallons as of mid February. Historically the rainy period has more system shutdowns and there hasn’t been a reporting of that in several months.

Report Status
The Remedial Action Plan Modification Response to Comments as well as the Year Three Quarter Four Operation and Maintenance Report are in house now (received 04/19/10) and will expedite my review of these now.

Milestone Update:
The most recent groundwater sampling data is from the week of February 23, 2010. The new data summary follows: The approved RAPMod stated that the goals for this site are 90% reduction for the chemicals of concern (COC) to contaminant target levels (CTLs). The key milestone wells that have been sampled for this project are wells #AW-3, AW-7, AW-11, AW-22, AW-24, and MW-5. However, there’s a larger set of wells in this report since this one is an annual report. Of the eighteen monitor wells sampled this time, only four of them are above groundwater cleanup target levels.
· 14 wells below contaminant target levels (CTLs) : AW-2, AW-3, AW-7, AW-11, AW-18, AW-22, AW-24, AW-26*,AW-27, DW-11, MW-1, MW-2, MW-3, MW-6. *note. AW-26 was one of the assessment wells during our investigation around MW-5 and AW-10. This well had contamination, which has went away. It is one I recommending watching carefully for rebound, but it is below Chapter 62-777, F.A.C., Table 1 Groundwater Cleanup Target Levels for all COCs analyzed.

· AW-10. Although this well has decreased a great deal, it still has significant contamination.

· MW-5K – This well was usually linked to AW-10 in my past updates. By comparison, MW-5K was always much higher than AW-10. MW-5K has decreased and is now has levels comparable with AW-10.

· AW-28 – This well is the most contaminated well. It has been sampled three times since it was installed last year and , although the values have fluctuated, it is a source well. This well will become a milestone well for the Remedial Action Modification implementation.

· MW-9 – This well decreased dramatically a year ago and is at plateau with very low levels of benzene still present.

As usual, I’ll send you a new update next month as well, on June 1, 2010. Please feel free to call me anytime if you need additional information or have any questions.

December 1, 2009

Ms. Mills,
I would like to take this opportunity to give you our thirty-seventh monthly update on the project.

General Status:
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.

System Runtime:
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.

Report Status
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.

Milestone Update:
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.
