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

be limited toLevel1,Level2and the central stair landingon theMezzanineLevel.Samples

for confirmation purposes, ceramic tile, grout and thinset mortar typically do not contain

contingency.

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.

AMOSITECONTAMINATION

The1993 report indentifiesasbestos contaminationon theoverheadgridandwithin theeast

wallof theCashAreaandoverheadwithin theguardareaandpistolrange.The1993report

identifies the contaminationas 60%70%Amosite,5%10%Chrysotileand2%5%Crocidolite

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.
