rh� KLEINFELD[R <br /> � petroleum-ctained soil appeared to be limited in e�tent and ���as believed to be associated nith <br /> leakage from a freight elevator. Analytical results detected elevated ]evels of TPH (as heavy oil) <br /> � of 14,000 mg/l:g, ���hich aze well aUove the MTCA Method A cleanup le��el of 200 mg/l;g. No <br /> evidence of halogenated VOCs �vas reported. Mr. Kanc reporied that the petroleum-stained soil <br /> � was removed and transported offsite for disposal. Follo���ing removal of tl�e peVoleum-impacted <br /> soil, a post-excavation soil sample �i�as collected and contained non-detectable levels of <br /> petroleum hydrocazUons. <br /> � In October 2000, Graha�n Conlracting demolished the existing manufac[uring building and <br /> � identified a 6-inch diameter by 6 feet long abandoned steel pipc bencath the concrete f]oor. The <br /> pipe was reportedly filled wilh oil and dirt. Analytical results confirmed the presence of <br /> � petroleum hydrocarbons ���ithin the sleel pipe. Kane C-nviromnental reported Uiat the matcrials in <br /> � the pipe and the pipe itself were removed and transporied ofT'site for disrosal. Although Geld <br /> represenlatives observed no e��idence oP leakage from thc pipe, approzimately 4 tons of soi] was <br /> � rentoved Gom the area surrounding tlie pipe as a precautionary melsure and transported ofTsite <br /> for treatment at the TPS Tecluiologies facilily in Tacoma, Washington. Following mmoval of <br /> � the pipe, a post-excavation soil sample �vas collected beneatl� il�e pipe and revealed Ie�v levels of <br /> TPH (as heavy oil) concentrations of 160 mg/1<g, ���hich was below �cology's MTCA 1�lcthod A <br /> � cleanup level of 200 mg/Icg. <br /> � 3.0 PUI2POSE AND SCOI'Is OF SERVICES <br /> � <br /> The objective ofthe Phase I GSA Update and Limited Phase II Surface Soil Chazacterization ��as <br /> � to: (1) evaluate cunent site conditions in re]ationship to the findings presented in the original <br /> Phase I, (2) furiher assess the suUsurface soil conditions for the potential presence of <br /> � contaminated soils, and (3) provide mcommendations regarding thc site redevelopment ���ith <br /> respect to environmental issues associuted�vith the subject propeny. <br /> ITo accomplish the project oUjecti��es, �i�e conducted the follou•ing scope of sen•ices: <br /> I • Conducted a thorough review of previous invesiigations conducted by ADaPT <br /> � �ngineering (August 1999), Kleinfelder (September 2000), and Kane <br /> Environmental (November 2000) and other available infomiation associated with <br /> tl�e subject property. <br /> . Performed a site recom�aissance at the subject property and observe changed <br /> � conditions and use pattems since Aie completion of the prcvious Phase I L-SA. <br /> I 43360/SEAAR046.doc p�r�a���� <br /> Cep�n_h�'_UOQKIcinfcldcrinc. - O <br />
