I would like to take this opportunity to give you our Thirty-first monthly update on the project.
I am happy to report that it looks like the funding crisis with the FDEP Petroleum Cleanup Program will not severely impact this site.. Since the last update, the priority score threshold for funding was raised from 45 points to 60 points.. This site will continue to be funded since it has a priority score of 60 points. The change took effect on May 14th, but FDEP is soon going to be issuing an implementation guidance that will put some restrictions on the way work orders are written and verbal change orders are handled. I expect we’ll have that guidance in the next week. Until we get the guidance the Bureau Chief said to carry on with business as usual.
Report Status / General Status:
There is still the same general optimization strategy as was presented in the last update (That multiphase extraction points 9,15,16,18,20,21,22,23,24 were shut down, thus only leaving up MPE-1,2,3,4,5,6,7,8,10,11,12,13,14,17 & 19 running. MPE treatment points MPE-3, MPE-4 and MPE-5 are being maximized for treatment around MW-5.
The floor of the equipment building on the air compressor side is deteriorating and will need to be repaired for health and safety reasons. I don’t see that this would affect the operation of the system or cause any delay to repair though.
The gallery failsafe has been intermittently triggered during heavy rain events by a short circuiting but I understand that last week Argus sealed the wires such that a short circuiting won’t keep recurring. I don’t believe the gallery has had any problems with the percolation of the treated water.
In the last update, we had three reports in house, all of which have been reviewed and letters are awaiting administrative review and should be sent out very soon:
* We approved the Pilot Test Plan (received 04/27/09) and are requesting a cost proposal to implement it. .
* We responded to the Year Four Quarter Four Operation and Maintenance Report (received 04/28/09). Our May 29th response letter congratulated Argus on improved run time. The Division recommended optimizing water and vapor recovery in the area of MW-5 and AW-10 (as well as AW-3) lowering the submersible pump intakes in the multiphase wells. We noted that MPE-8 and MPE-9 were apparently running where we had thought they were turned off and that Argus will continue to optimize groundwater and vapor recovery based on the groundwater and vapor data collected.
* The pre-Remedial Action Plan Modification Assessment (received 04/20/09), where we concur with Argus that it would be appropriate to install a monitoring well south of AW-26 near the infiltration gallery as well as one between MW-2 and AW-6 on the east side of Philadelphia Avenue. In this letter we ask Argus to consider the need for another one approximately 9 ft west of MIP-12 and equidistant between MW-2 and AW-6. Although our draft of this letter requests this to be done with a change order, it would have to be done with a work order since the FDEP has requested change orders to cease.
The next report due from Argus is the Year Three, Quarter 1 Operation and Maintenance Report, which is due July 30, 2009, but should be able to be submitted earlier.
I don’t have updated milestone data this time, but should have some relatively soon. I will send the next update on July 1, 2009, but may send updated milestone data before then. Please feel free to call me anytime if you need additional information or have any questions.
