F-LINE DITCHES, SFAAP-010
SITE DESCRIPTION
The F-Line Area is located in the east-central portion
of SFAAP. The F-Line consisted of a blender house
in which explosive propellant was received and
blended with lead salicylate; rolled into sheets; slit
and wound into carpet rolls; and extruded by large
hydraulic presses into solid propellant grains. Any
propellant that was on the floor was washed into the
drain with the wastewater. Most of the effluents
were then discharged, via unlined ditches, to settling
ponds and eventually to Spoon and Kill Creeks; however,
one group of the ditches discharged directly to a
field adjacent to Spoon Creek. The F-line ditches
were located on the east side of the F-Line press
houses. Occasionally, propellant solids settled in
these ditches before reaching the ponds. The ditches
were used periodically from the early 1950s to 1971.
Several ditches served as discharge points for runoff
from storm drains along the streets in the area
(USATHAMA, 1980; USAEHA, 1985b; USAEHA,
1987; PRC, 1990).
The draft RFI indicates nitroglycerin in soil at concentrations
that exceed EPAs target risk range for
carcinogenic risk. Lead was found at concentrations
exceeding EPA and KDHE guidance values.
The Final Corrective Measures Study has been completed
and recommends soil remediation by excavation,
stabilization and incineration. The stabilization
study began in September, 1999.
PROPOSED PLAN
Approximately 5,000cy of soil will be removed by
excavation, stabilization, and incineration will be performed.
Five years of LTM will be conducted.
