UNIDENTIFIED SUBSTANCE (OIL) WASTE SITE

 

SITE DESCRIPTION

This site covered an area approximately 20 by 20 feet. The site is situated in the central portion of the IAAAP, northwest of Yard O along the south side of the railroad track, approximately 150 yards west of Plant Road I.

The unidentified substance thought to be road surfacing oil was discovered on July 16, 1985 (IAG, 1990). The source of the oil spill is thought to have been a leaking railroad tank car (RI/FS Task Order, 1990)

The spill area is located 15 to 20 feet south of the railroad track bed. According to the on-site personnel, this area has been covered with approximately 10 feet of fill material which has created a small incline sloping up and away from the railroad track bed.

The SI sampling was completed in 1991 and no significant contamination was found.  This site requires NFA under the IRP.

This site is considered in NFA per PA/SI, but may need to be reopened for additional sampling to support the no further action determination.
