Problems/Comments

A 4,000-gallon fiberglass underground storage tank (UST), utilized for the storage of diesel fuel, was removed from the north side of the Federal Express Hangar on October 3, 2013 (Faciltiy ID 2264; DEC Tank ID 6; Owner Tank ID 11). During the UST removal activities, the excavated soils were field screened and temporarily stockpiled on plastic sheeting. After the UST was removed from the ground it was rinsed, crushed, and hauled offsite for disposal. A total of 29 soil samples were field screened for volatile organic compounds (VOCs), of which 4 confirmation soil samples (3 from below the tank and 1 from under the piping), and a duplicate soil sample (from beneath piping), were submitted for laboratory analysis. The confirmation samples were analyzed for gasoline range organics (GRO), diesel range organics (DRO), benzene, toluene, ethylbenzene, and total xylenes (BTEX), and polynuclear aromatic hydrocarbons (PAHs). Fluoranthene and pyrene were present in three of the soil samples; however, at concentrations several orders of magnitude below the approved cleanup levels. Following the excavation activities, and in the absence of visual or olfactory signs of contamination, the temporarily stockpiled soils were replaced in the excavation.
