Problems/Comments
Sites SS107 and SS108 are associated with historical releases of asphalt tar and crushed tar barrels. Site SS107 is in a wooded area north of the dike road surrounding the airport where, in the 1940s, an airport expansion runway was planned. Site SS108 is in the airfield south of the runway where asphalt tar was processed in a hot mix plant. Following a 1945 flood of the Yukon River, the tar barrels were dispersed across these areas, and at some locations a tar “pit” of liquid tar formed. Heavy equipment was used during the 1950s to crush and bury the exposed tar and barrels in the airfield.
