Technical Report ·
OSTI ID:484689
This PA/SI Report presents information on potentially contaminated areas identified in the PA process as Areas of Concern (AOC`s) at the 157(th) Air Control Group (ACG), Jefferson Barracks ANGS, St. Louis, MO. Information obtained through interviews, review of station records, and field observations resulted in the identification of four potentially contaminated disposal and/or spill areas (AOC`s). The four AOC`s identified include the Disposal Area (AOC-A), Storage Area (AOC-B), Drainage Ditch (AOC-C), and Waste Oil Dump (AOC-D). These AOC`s were investigated, using screening and confirmation activities, to determine if contamination exists that justifies further investigation as an IRP site. Considering the results of the PA/SI conducted, no additional IRP activities are warranted at AOC-A, AOC-C, and AOC-D. At AOC-B additional investigation is recommended because the vertical and areal extent of TPH contamination is in excess of MDNR cleanup guidelines. In addition, the PA/SI Report recommended a risk-based evaluation to determine action levels for PAH impacted surface soils at AOC-B.
