Borrow material excavation is planned to occur in 2002. Site reclamation would begin during the'same year. Topsoil materials will be removed from the borrow area for temporary stockpiling and ": subsequent replacement as a planting medium during reclamation of the borrow area. None of the topsoil will be used as fill material for the third runway embankment. Borrow Area 4 lies,within part of the Puget Sound region impacted by fallout of arsenic-bearing airborne emissions. The fallout originated from historical ASARCO copper smelter operations in Tacoma. Chemical testing of topsoil from Borrow Area 4 detected mean arsenic concentrations comparable to those commonly present in undisturbed surficial soils elsewhere within the footprint of the smelter plume. Maximum arsenic…
