On September 1, 2005, EPA notified IDEQ that the OSLTF funding for the site was nearing the ceiling and EPA was not able to secure additional funding due to the lack of a continued threat of a release to surface water (this decision was based upon months without collecting any more oil). EPA presented IDEQ with the following four options for the site: (1) EPA completely removes the treatment system then demobilizes from the site; (2)EPA removes only the carbon system and ground water pump then demobilizes from the site; (3) EPA removes only the carbon system and then demobilizes from the site; (4) EPA operates entire system for one month as is and IDEQ assumes complete control of the site and all costs associated with the treatment system.
On September 6, 2005, IDEQ indicated it would like EPA to remove all of the equipment that was used in the groundwater suppression system, and leave the passive free product skimmers, control panel and tank (all the equipment IDEQ currently owns). In addition, the requested that EPA coordinate with them and the local Power vendor so that IDEQ could be left set up functioning with the original free product recovery system operational.
On October 1, 2005, USCG NPFC agreed to provide EPA with an additional $20,000 to cover demobilization costs associated with the Demobilization Plan. The USCG increased the FPN ceiling from $590,000 to $610,000.
On October 4 and 5, 2005, the EPA ERRS contractor mobilized to the site to carry out the Ashton Texaco Demobilization Plan. The EPA ERRS contractor disconnected electricity from the groundwater treatment system and removed all of the leased equipment including the groundwater depression pumps, control boxes, and water treatment system. The EPA ERRS contractor shipped all of the leased equipment back to the appropriae vendors. The EPA ERRS contractor disassembled the treatment system shed and removed any aboveground piping. The City of Ashton completed the capping of the connection to the sanitary sewer system. The EPA ERRS re-installed the product pumps and reprogrammed the control boxes. This system was purchased by IDEQ and will be maintained by the State.
November 21, 2005, the EPA ERRS Contractor's subcontractor finished the additional work on the site. No additional site work is anticipated.
