If it'sof concemto Burien,itmay be sensitiveinothercommunitiesinthe vicinityas well (e.g. SeaTac, NormandyPark,Tuk'wila). We ware quitecareful,inrespondingand negotiatingwithLoneStar�GlacierNW onconditionsofthe EIS, toassurethat no arsenk_wouldbe exportedfromthe MauryIslandgravelpitunderthe pitexpansionEIS. While thisdidnotsatisfythe residentsof Vashonand MauryIsland,Jtwasdesignedto assurethatarseniccontaminationassociatedwithsurfacesoils atthe pitwere notexportedto f'_[sites,as wellas assuringthatenvironmentalandpotentialhumanhealth_mpactsonthe island(s)were mitigated.
