Ms. Mills,I would like to take this opportunity to give you our Fifteenth monthly update on the project. The startup occurred in late February 2007, so we are approaching the one year mark of our scheduled 4-year cleanup schedule. As a quick abstract of the below update: the site is temporarily shut down due to administrative issues and the cumulative data shows three of the key wells not meeting milestones.Report Status:Terramax completed the work order and a final report is expected from them before January 10th. There are a few reports in house (already submitted by Terramax) here at Orange County to issue letters on as well. I expect we will have our response letters ready to send out very soon. I will provide you a PDF copy of these letters when they are ready if you wish.Designated Contractor Change: The property owner has submitted a Contractor Designation Form (CDF) changing the contractor from Terramax to Argus Consultants last month. The Florida Department of Environmental Protection reviews these and upon approval of the CDF, a new work order is to be issued to carry on with routine operation and maintenance. This administrative change will result in the system being left off due to no work order to fund the operation of the system. A work order cannot be issued until the FDEP has approved the contractor change. This is unfortunate, but I don’t think it will delay the project by very much (one month, two at the most). Therefore, next month’s update may be very brief.In the meantime, I checked the qualification status of Argus and see that they indeed are qualified under the FDEP preapproval program, so when the CDF is issued a work order should be relatively quick to issue and get back started again. They will have to renew their qualification status in February though. General System Status since Startup in February 2007: As you know from prior updates, we have experienced a great amount of downtime on this project due to shutdowns from leaks, noise complaints, a design change to address vapor recovery, etc. Now the consultant is being changed in between work orders. However, most of the issues have been worked out with some general ones that may still remain.
- The compressor that pneumatically drives groundwater recovery was shutting down due a faulty heat sensor. It was erroneously reading a high temperature which engaged the failsafe mechanism to shut it down. This happened more than once in the last quarter, but Terramax believes this has been fixed.
- One improvement was also made to the groundwater recovery measurement devices (flow meters), which will more accurately let us know how much water is being recovered from each of the 24 wells. As of last week, a few wells had little to no recovery, while flow meters on others showed much higher cumulative amounts. This is a trend we will need to monitor closely in the upcoming year.
When operation and maintenance resumes with the new consultant and new work order, I will be watching the above carefully was well as maximizing our treatment efficacy in the treatment points adjacent to the most impacted key wells (below).Milestone Update:I will attach a PDF of the most recent milestones if you wish after I complete my full review of them. This December 23, 2007 sampling event is the third milestone sampling event because one of the events of the work order was reduced from the work order while the design change was implemented. From my cursory review of the milestone data provided to me today via email, it looks like the data shows:
- Key Well MW-5 – This well is NOT meeting milestones for the Naphthalene compounds. I note that it is only slightly meeting milestones on the other constituents and the overall trend in concentration reduction in other compounds is slowing down with this new data. This well is located closest to treatment point MPE-4 towards the south along Philadelphia Avenue.
- Key Well AW-3 – This well is NOT meeting milestones for several compounds including Ethyl Benzene, Xylenes and Naphthalenes. There were increases in each of these and also a slight increase in benzene (although benzene is meeting milestones). This well is located closest to treatment points MPE-3 and MPE-7. This one is also towards the south (but north of MW-5).
- Key Well AW-7 – This well is NOT meeting milestones for the Naphthalene compounds. There isn’t a very steep reduction trend in the other compounds either although the other constituents meet milestones. This well is located closest to treatment points MPE-10, MPE-11, and MPE-12. This one is located in the west central portion of the project site between Philadelphia and Alden.
- Key Well AW-11 – This well is meeting milestones for all target compounds. This well is located closest to treatment point MPE-1 and is adjacent to the power pole just outside of the remediation compound to the south on the property Mr. Scala leases. Although this well is indeed meeting milestones, benzene still remains above groundwater cleanup target levels.
- Key Well AW-22 – This well is meeting milestones for all target compounds. This well is located closest to treatment point MPE-24 and is slightly north of the remediation compound alongside Philadelphia Avenue where the propane tank is located. I believe this one has reached groundwater cleanup target levels for all constituents.
- Key Well AW-24 – This well is meeting milestones for all target compounds. This well is located between treatment point MPE-17 and MPE-19 and is in the south central portion of the project. I believe this one is also on the property that Mr. Scala leases. This well has almost reached groundwater cleanup target levels for all constituents.
Please feel free to call me anytime if you need additional information or if you would like me to find something in our files. Also. I am always available to meet you onsite if you want to discuss the site in detail. Damon Taylor, CFEA, LEP Orange County Environmental Protection Division 800 N.
