AOC Work Plans <br /> Millwork Building <br /> Two surface soil samples(locations not depicted on maps available for rev iew)were collected and <br /> analyzed by Kleinfelder in the vicinity of the wash down area near the Mil work Building in 1987 <br /> and analyzed for formaldehyde and phenols only. Formaldehyde and pher.ols were detected at <br /> maximum concentrations of 45 and 0.92 mg/kg respective. Kleinfelder coi icluded that because <br /> these concentrations were below applicable regulatory cleanup levels,no f uther work to evaluate <br /> the extent of these compounds was warranted. <br /> In December 2001,AGE installed an additional boring PB-8 in the Millw k Building washdown <br /> area and collected a grab groundwater sample from the boring. The sampl was analyzed for <br /> TPHg,TPHd,TPHmo,VOCs, and formaldehyde. With the exception of Hd and TPHmo, <br /> detected at concentrations of 0.089 and 0.330 mg/L respectively, all reque ted compounds were <br /> below laboratory reporting limits for the groundwater sample. <br /> Priming Building <br /> No information is available that indicates sampling of surface soils or grou adwater has ever been <br /> performed at the Priming Building Area(Plate 4.5). <br /> Saw Filing Room <br /> According to Kleinfelder(Kleinfelder, 1992),the saw filing room,located Do the north end of the <br /> Finger Joints/Box Factory Building(Plate 4.5),was utilized for pitch and 1 ibricant removal using a <br /> lye solution(sodium hydroxide)prior to being used for sharpening saw bh des. The lye solution <br /> was collected during the cleaning operation,but rinse water was reportedI3 discharged onto surface <br /> soil north of the saw filing room. The soil north of the saw filing room dra ined into a culvert which <br /> was likely the western ditch. In 1987 Kleinfelder collected two shallows it samples(locations not <br /> depicted on maps available for review)between the discharge point and th culvert.
