The 1993 report documents that 12 samples of vinyl floor tile and associatedmasticwere
collectedfromallsixfloors.Ofthose12samples,onlyonesampleoftileandmasticcollectedon
Level 1was non asbestoscontaining. Based on the 1993 report, all original vinyl floor tile
(typically 9x9) and associated mastic should be considered asbestoscontaining unless
confirmed otherwise through sampling and laboratory analysis. Based on sampling
documentedinthe2010report,samplingconductedbyMGIduringtheMarch7sitevisit,and
MGIsMarch7fieldobservations,theremainingasbestoscontainingvinylfloortileappearsto

Lead(Pb)mayalsobepresentintheceramictileglazing.Ifdetectibleconcentrationsofleadare
present, removalof theceramic tilewouldbegovernedbyWashingtonAdministrativeCode
(WAC) 296155176 (Lead [in construction]).Disposal of thematerialwouldbe regulatedby
WAC173303 (DangerousWasteRegulations).According toWAC173303090,a solidwaste
which exceeds fivemilligrams per liter (mg/l) as determinedby the Toxicity Characteristic
Leachate Procedure (TCLP) for lead (Pb) would be designated a dangerous waste for the
purposeofdisposal.
Due to the current asbestoscontaining assumption, theattacheddrawings show the location
and quantity of ceramic floor and wall tile. This material should be tested to confirm
occupational hazards andwaste designation,but past experience suggests that ceramic tile,
mortarandgroutwerenotmanufacturedwithanasbestoscomponentand the leachablityof
lead inceramic tile is typically too low toresult inaDangerousWastedesignation.As such,
MGIdoesnotanticipatethatregulatoryrequirementsassociatedwiththeremovalanddisposal

notbeen itemized in Table 3but is incidentally accounted for in the demolition/abatementbudgetestimate.

The1993 report indentifiesasbestos contaminationon theoverheadgridandwithin theeast
wallof theCashAreaandoverheadwithin theguardareaandpistolrange.The1993report
identifies the contaminationas 60%70%Amosite,5%10%Chrysotileand2%5%Crocidolite
asbestos and estimates thequantity of this contamination tobe 13,000 square feet.The 2010
reportslightlymodifiesthedescriptiontoamositecontaminationonoverheadgrid Ground
Floor above the SecurityOffice/CashArea and reports the quantity as 12,000 square feet.
Accordingtothe1993report,thesourceofthecontaminationisfromtheremovalofsprayedonamositeintheoverheadoftheeastsideoftheGroundFloorinMarch1986.MGIinspected
the spaces listed in Table 1 and noted dusty conditionsbut did not visually confirm the
presenceofparticulatesuggestiveofgrossamositecontamination.
To investigate thereportofcontaminationand toquantifyasbestos insettleddustwithin the
Ground Floor Security Office/Cash Area, MGI utilized a microvac sampling technique in
accordancewith thesamplingprocedurespecified inASTM International3methodD5755094.
Briefly, the sampleprocedure involvedvacuumingaknown surfaceareawitha standard25

Preparation and analysis of the above samples was conducted in accordance with the ASTM # D-5755-03 for the identificationof asbestos in dust. Briefly, the samples were sampled by using a microvac technique onto 0.45 m pore size mixed celluloseester (MCE) filters. Sample cassettes were rinsed in distilled, particle-free water, sonicated lightly to homogenize and removedparticulates. Aliquots were taken and filtered onto 0.22 m pore size mixed cellulose ester filters, then air-dried. The sampleswere carbon coated at high vacuum with a thin layer of carbon, placed on 200 mesh copper grids and allowed to dissolve in N,N-Dimethlyformamide / Acetone baths until cleared of filter debris.
Analysis was performed using a transmission electron microscope equipped with an EDS X ray analyzer. The samples wereanalyzed at an approximate screen magnification between 15,000 - 20,000x, with an accelerating voltage of 100 KV. The sizingof grid openings was performed using a calibrated digital imaging system at low magnification.
Disclaimer The results reported relate only to the samples tested or analyzed; the laboratory is not responsible for data collected by
personnel who are not affiliated with the laboratory. Results reported in both structures/cm3 and structures/mm2 are dependenton the sample volume and area. These parameters are measured and recorded by non-laboratory personnel and are notcovered by the laboratorys accreditation. Interpretation of these results is the sole responsibility of the client.
If further clarification of these results is needed, please call us. Thank you for allowing the staff at Lab/Cor, Inc. the opportunityto provide you with the analytical services.
