No report has been submitted during the current reporting period. Based on sub-slab vapor results of samples collected in June of 2009, a sub-slab depressurization system would be required as a continuing obligation of site closure due to the TCE and PCE small commercial VRSL exceedances in the western portion of the building. Due to the age of the vapor results, additional sub-slab vapor is recommended to confirm the continued presence of small commercial VRSL exceedances. A Change Order Request (COR) is being prepared for submittal in early August to perform the additional sub-slab vapor sampling as well as the Pressure Field Extension (PFE) testing to adequately design a depressurization system if necessary.
