"Disposal
Three options are available to accommodate disposal of the excavated yard soils. The
first option would be to simply haul the contaminated soil to an offsite sanitary landfill for use as
daily cover and disposal. This option is currently being used for an ongoing time-critical
removal action at the site.
The second option would be to use the soil excavated from the residential yards as
beneficial fill in the construction of an industrial facility. Lead-contaminated soils at the site are
considered a risk to human health only in residential settings. In certain instances, removed soils
could be safely used in an industrial setting without creating a risk to human health. Constructed
engineering features may also be necessary to protect human health and the environment.
Option three would consist of constructing an offsite repository on privately owned land.
This alternative may be the most costly because significant design and site preparation would be
required for construction of the facility. This option would also be limited by the availability of
land and willingness of landowners to maintain such a facility. A constructed offsite repository
could be the preferred option should land belonging to a Responsible Party for the site be
identified and the repository constructed and maintained by that Responsible Party."
