AOC Work Plans PCP was utilized on a periodic basis to treat wood utilized for lumber storage purposes,but was reportedly not part of the normal industrial process. An area where treated wood,lead batteries, and possibly some containerized PCP were stored is present west of the Fi iger Joints/Box Factory Building in the truck parking area shown on Plate 4.1.1. A second area w 'ch contained a former concrete tank(UST 18820010)which extended approximately 10 feet into the subsurface south of the Ray Bond area of the Finger Joints/Box Factory Building was utilized o treat the wood `stickers'. Previous Investigations Truck Parking Area In 1985,BNI collected soil samples (at depths of 0.5, 1.0, and 2.0 foot bgs)from three test pits for lead,petroleum hydrocarbons,PCP,and PCBs at the Truck Parking Area. All petroleum hydrocarbons and PCBs were reportedly below the U.S. Environmental Pr Mection Agency (USEPA)Preliminary Remediation Goals(DRGs). Lead concentrations A ere reported to be within the background range of 21 to 31 milligrams per kilogram(mg/kg)in all s imples except for one sample collected at 0.5 foot bgs with a detected concentration of 200 m g. All PCP samples were below the residential PRG of 3.0 mg/kg with the exception of one sa ple detected at a concentration of 33 mg/kg. In 1987,Kleinfelder collected additional soil samples for PCP analyses from eight shallow test borings(Shelby tubes driven to 1.5 foot bgs)in tht vicinity of the 33 mg/kg PCP detection. The analytical results for PCP from all samples,with the c xception of one detection at a concentration of 0.43 mg/kg,were below the reporting limit;. The only sample analyzed for dioxin/furans was below reporting limits. In 2001,AGE drilled two soil borings to depths of 60 feet bgs in the Par ng Area(PBI and P132). One soil sample was submitted for laboratory analyses from each boring 7 a depth of 5 foot Draft KB61125 workplan-ESC MACTEC Engineering and Consulting, Inc. 13 September 28,2005
