Problems/Comments

Site OT617 resides in the Lower Camp at Cape Lisburne LRRS and consists of the Water Pump House Building 130 (pump house) where a powered water pump was once fueled by a 300-gallon underground storage tank (UST) located on the south side of the building. The UST was reported to contain either diesel or MOGAS (motor gasoline) fuel. In 1991, the former UST was removed and reportedly replaced with a 300 gallon, unleaded MOGAS aboveground storage tank (AST). The replacement AST was last documented onsite in 1998. The sources of contamination at Site OT617 were anticipated to be petroleum hydrocarbons including diesel range organics (DRO) and gasoline-range organics (GRO), potentially from leaks or spills as a result of transfer or refueling activities at the UST. Areas of interest included immediately north, east, and south of the pump house building; the west side of the pump house is occupied by two 500,000-gallon water tanks (Water Tank 1 and 2). Subsequent investigations indicated no petroleum hydrocarbon concentrations exceeding the CULs were detected in any soil samples analyzed from Site OT617, which was the former UST location. Data indicate that the former UST location south of the pump house building is not a source of contamination as previously hypothesized. However, soil in the area northeast of the pump house in surface and shallow subsurface soils (zero to four feet below ground surface) found concentrations of DRO and RRO but they were less than CULs.

9/6/2017 Site Characterization Report Approved Approval of Site Characterization Report for OT617. Comments on draft versions were previously addressed. The report documents a release investigation at Site OT617 conducted between July 18 and 23, 2016, conducted in accordance with the DEC-approved UFP-QAPP Work Plan. The work included advancement of soil borings and analytical sample collection to characterize the nature and extent of contamination around the Water Pump House. The soil borings were advanced north, east and south of the pump house. John Carnahan
12/11/2017 Cleanup Complete Determination Issued Cleanup Complete letter sent to AF. Petroleum hydrocarbons were a Potential Chemical of Concern and have been assessed and not detected above cleanup levels (CULs). Contaminants identified above CULs include arsenic in soil and arsenic, barium, and thallium in suprapermafrost water; however, the source of metals is determined to be naturally occurring and unrelated to the contamination in question. Soil and supra-permafrost contamination at the site are below the approved cleanup levels suitable for residential land use or naturally occurring at the site. This site will receive a “Cleanup Complete” designation on the Contaminated Sites Database, subject to the following standard conditions. John Carnahan
