South Groundwater Contamination Plume |
The Removal Action is subdivided into five parts: 1)
provision of an alternate water supply to an affected industrial user, 2)
installation of a pump and discharge system for South Plume groundwater, 3)
construction and operation of Interim Advanced Wastewater Treatment systems, 4)
South Plume groundwater monitoring and installation of homeowner treatment
systems, and 5) groundwater modeling and geotechnical investigations. Field
activities for Parts 1, 2, and 3 were completed prior to FY 93, and operation
of each of the units continues. Part 4, which includes sampling of private
homeowner and existing RI/FS wells in the South Plume area, continues. In
addition, as part of the OU 2 dispute resolution with EPA, DOE agreed to
install a South Plume Interim Treatment system for partial treatment of South
Plume discharge water to further reduce uranium discharge to the Great Miami
River. Installation was completed and operation commenced in March 1994. Part 5
field activities were completed in February 1994. |

Silos 1 and 2 (Bentonite Installation) |
This Removal Action required the installation of
bentonite clay in Silos 1 and 2 to eliminate the threat posed by a potential
release of residue and the acute release of radon gas. Monitoring activities
for this Removal Action continue. |
| 5 |
K-65 Decant Sump |
The objective of this Removal Action requires the
removal of sludge and liquid from the K-65 Decant Sump Tank. The tank has been
accumulating liquid since it was emptied in 1991. Once the tank is 80 percent
full, repumping is required. Current activities include monitoring the liquid
level and performing maintenance as needed. |
| 9 |
Removal of Waste Inventories |
FEMP procedures for the Removal of Waste Inventories
were submitted to EPA in August 1991. These procedures detail the methods used
in packaging and shipment of low-level waste, including thorium, from the FEMP.
Updated procedures were approved by EPA in October 1992, and in 1995 Removal
Action No. 9 was amended to include mixed waste inventories. Removal Action No.
9 will continue through issuance of the OU 3 ROD. There were 593,000 cubic feet
of low-level waste disposed of in FY 95, 43,460 gallons of mixed waste were
shipped to the TSCA incinerator, and 2,317 cubic feet of solid mixed waste were
shipped to Envirocare. |

Active Flyash Pile Controls |
This Removal Action requires the active flyash pile
to be placed under control by regrading, the application of dust suppressants,
and installation of wind barriers and fences. Phase I, which involved the
completion of interim surface stabilization, is complete. Phase II, which
involves completing the active flyash pile controls, is ongoing. |
| 12 |
Safe Shutdown |
Safe shutdown procedures were submitted to EPA on
October 30, 1991. Updated procedures were approved by EPA in October 1992.
These procedures detail the methods to be used to place the former production
facilities at the FEMP into a safe and permanent shutdown configuration. Field
work began in May 1993 and continues for several of the buildings. |
| 17 |
Improved Storage of Soil and Debris |
The objective of this Removal Action is to improve
the soil and debris storage locations at the site by providing run-off controls
and covered structures. The Removal Action work plan was approved by EPA in
October 1992. Field work is ongoing. |
| 26 |
Asbestos Removals |
The objective of this Removal Action is to mitigate
the potential for fugitive releases of asbestos. A compendium of procedures
supporting this Removal Action was submitted to EPA in May 1992. Activities
include small- and large-scale in-situ repairs, encasement, encapsulation, and
removals. Field work is ongoing. |
