In May 2005, the BRAC Commission recommended closure of
Lone Star Army Ammunition Plant (AAP). Lone Star AAP loads,
assembles, and packs munitions. From 1943 to 1944 the Old
Demolition Area (ODA), Site 17, was used to destroy faulty or
nonstandard explosives. Environmental studies revealed
explosives and metal contamination in the ODA. EPA placed
the ODA on the NPL in 1987. RCRA sites investigated include
surface impoundments, landfills, fuel storage areas, and load
lines. Investigations revealed soil contamination with solvents,
metals, and explosives at some sites and groundwater
contamination at one site. The Army and EPA signed an
interagency agreement (IAG) in 1990. In FY01 and FY06, the
installation solicited interest in forming a Restoration Advisory
Board (RAB), but interest was insufficient. The Army completed
a 5-year review in FY06.
The ODA is the only CERCLA site at the installation. One
Record of Decision has been signed to date. The cleanup
progress at Lone Star AAP for FY02 through FY05 is detailed
below.
In FY02, the Army completed construction of the soil cover
erosion controls at Site 17 (the NPL site) and initiated the
remedial design (RD) at Site 16 (High Explosives Burning
Ground). The remedial action (RA) at Site 33 (G Ponds) was
completed. The installation determined that the RD at Site 422
(B 8 Battery Washdown Sump) was unnecessary. The Army
completed an inventory of closed, transferred, and transferring
ranges and sites with unexploded ordnance, discarded military
munitions, or munitions constituents. The inventory identified
one closed range (Site 17), which the Army had previously
included in the Installation Restoration Program (IRP).
In FY03, the installation continued groundwater monitoring at
Sites 2, 17, and 34.
In FY04, the installation continued long-term management
(LTM) at Sites 2, 17, 24, 33, and 34. Remedial investigations
(RIs) began at Sites 6, 9, and 101. The installation completed
the RD and began the soil removal action at Site 20. The Army
received state approval of no further action (NFA) for Sites 78,
79, and 80.

In FY05, Lone Star AAP completed the RI at Site 101 with NFA.
The installation initiated LTM at Site 16 and continued LTM at
Sites 2, 17, 24, 33, and 34. RAs were completed at Sites 9, 16,
and 20. The installation initiated RA at Site 6.

Lone Star AAP performed a 5-year review of the ODA, which
EPA approved. In response to the BRAC Commission's
recommendation to close Lone Star AAP, the Army initiated an
environmental condition of property (ECP) report and a CERFA
report.
The Army began the RA at Site 6; however, technical issues
delayed completion. Administrative issues delayed LTM at Sites
2, 16, 17, 24, 33, and 34. Technical issues delayed the
groundwater modeling study at Site 2.
The installation solicited community interest for a RAB;
however, no interest was shown.
p‰HT2ww‚€2€�������
The Navy conducted no Military Munitions Response Program
(MMRP) actions at this installation.
