The former Pantex Ordnance Plant began operations in 1942
as an Army Ordnance Corps facility. The property is now
owned by DOE and Texas Tech University (TTU). Operations
conducted on the active DOE site include fabrication, assembly,
testing, and disassembly of nuclear ammunition and weapons.
Sources of contamination have included burning of chemical
waste in unlined pits, burial of waste in unlined landfills, and
discharge of plant wastewaters into on-site surface water. The
southern part of the property is used as an experimental
agricultural research farm by TTU. DOE is solely investigating
sites on their property. EPA placed the property on the NPL in
May 1994. The U.S. Army Corps of Engineers (USACE)
established an electronic administrative record for the TTU
FUDS in FY03.
A preliminary assessment and site inspection (SI) in FY90
identified nine areas of emphasis for investigation. The cleanup
progress for Pantex Plant for FY02 through FY05 is detailed
below.
In FY02, USACE completed a work plan for DoD-related
investigations that Texas Natural Resource Conservation
Commission (TNRCC) approved. TTU, the landowner, and
potentially responsible parties (PRP) submitted a separate work
plan for investigations. Preparations for field investigation at the
former Bomb Loading Line area (Zone 9) began. PRP
discussions with TTU continued.
In FY03, USACE completed environmental investigations at
Zone 9 and other areas of concern (AOCs), including Zone 1,
the Burning Grounds, Carbon Black Pits, Landfill, and Lake
Mounds areas. In addition, USACE presented investigation
results for Zone 9 to TNRCC. DoD continued PRP discussions
with landowners. USACE established an electronic
administrative record for the TTU FUDS. USACE determined
the extent of explosives contamination in soil at Zone 9.
In FY04, USACE completed environmental investigations to
determine the extent of contamination for all AOCs, including
Zone 2, and continued investigations for sites that may have
required additional data. Additionally, USACE presented
investigation results for Zone 1, Zone 9, the Burning Grounds,
Carbon Black Pits, Landfill, Rock Pile, and Lake Mounds AOCs

to the Texas Commission on Environmental Quality (TCEQ)
(formerly the TNRCC), DOE, and TTU. PRP discussions with
TTU and DOE continued. The district prepared for a remedial
investigation (RI) report and feasibility study (FS) for cleanup of
all DoD responsible AOCs. No Military Munitions Response
Program (MMRP) work was performed at this property.
In FY05, USACE submitted a final RI report to regulators for
investigations at nine AOCs and performed additional SIs to fill
data gaps identified during the RI. USACE continued PRP
discussions with TCEQ, TTU, and DOE. Pantex Ordnance
Plant received an updated right-of-entry from TTU for a
two-year permit. USACE initiated preparation of a public
involvement plan (PIP).
p‰HT2s‚€2€�������
USACE conducted additional sampling and prepared an
addendum to the RI to fill data gaps. The PIP for former Pantex
Ordnance Plant was completed. USACE developed and placed
an administrative record in the Amarillo College and Carson
County Public Libraries. The Tulsa District, USACE, transmitted
the Installation Response Program (IRP) RI report to the state
regulators.
USACE developed an RI fact sheet, in preparation for public
distribution. TCEQ sent a letter to all PRPs and committed to
scheduling a meeting to establish responsibilities.
p‰HT2ww‚€2€�������
USACE revised the MMRP work plan and received regulatory
acceptance of the signed DOE Security Plan Agreement for
fieldwork execution. It also completed the fieldwork for the
MMRP RI. USACE developed the draft RI report and provided
additional requested information to the lead regulatory agency.
Administrative priorities delayed the MMRP fact sheet
development.
