Since 1948, the Army has repaired, rebuilt, and modified
combat vehicles and artillery equipment at the Anniston Army
Depot (AD) Southeast Industrial Area (SIA). Painting,
degreasing, and plating operations at the installation generated
wastes containing volatile organic compounds (VOCs),
phenols, heavy metals, and petroleum distillates. EPA placed
the installation on the NPL in March 1989, and the Army and
EPA signed an interagency agreement (IAG) in 1990. In 2005,
the BRAC Commission recommended Anniston AD for
realignment. Prior to FY01, the Army cleanup activities included
pumping waste from an unlined lagoon into a lined lagoon,
removing sludge and contaminated soil at RCRA corrective
action sites, installing groundwater interception and treatment
systems to remove VOCs and phenols, and sampling off-post
private wells and springs surrounding the installation. The latter
addressed community concerns regarding residential
groundwater wells. During FY98, the installation formed a
Restoration Advisory Board (RAB) and updated the community
relations plan. In FY01, operation of the new centralized
groundwater treatment facility began. The installation
completed 5-year reviews in FY99 and FY04.
Studies at the installation revealed soil and groundwater
contamination at 47 sites. To date, two interim Records of
Decision (RODs) have been completed by the installation. The
cleanup progress at Anniston AD for FY02 through FY05 is
detailed below.
In FY02, the installation completed the Alabama risk-based
corrective action for Solid Waste Management Unit (SWMU)
46. The Army completed the Ammunition Storage Area (ASA)
remedial investigation and feasibility study (RI/FS), proposed
plan (PP), and draft ROD. The Army completed an inventory of
closed, transferred, and transferring ranges and sites with
unexploded ordnance, discarded military munitions, or
munitions constituents under the Military Munitions Response
Program (MMRP).
In FY03, the installation drafted Alabama risk-based corrective
actions for SWMUs 45 and 46 (Building 6) and submitted them
to the Alabama Department of Environmental Management
(ADEM) for review. The installation completed the draft Phase II
of the combined groundwater remedial investigation (RI) and
Army

submitted it to regulatory agencies for review. The installation
used a preliminary groundwater flow-and-transport model to
generate a prioritized list of sample locations for monitoring
points and wells. The Anniston Water Works and Sewer Board
(AWWSB) and the Army completed an agreement for the
installation of treatment equipment necessary to remove
trichloroethlyene (TCE) from Coldwater Spring, which is the
source of water for AWWSB. As part of the agreement, the
Army funded air stripping equipment at the Coldwater Spring
Treatment Plant. Anniston AD identified two sites during the
MMRP inventory. Anniston AD continued to provide public
education through the RAB on the health effects of TCE. The
installation formed two tiers of partnering teams with the U.S.
Army Corps of Engineers, the U.S. Army Environmental Center,
ADEM, EPA, and selected contractors.
In FY04, the installation submitted the draft final SIA Soil
Operable Unit (OU) ROD and the draft final ASA OU ROD. The
Army submitted the draft final 5-year review to the regulators
and awarded the technical impracticability evaluation contract.
The installation completed the site inspection (SI) for the two
sites identified in the MMRP inventory.
In FY05, the installation completed Phase III comprehensive
groundwater RI and submitted it to regulatory agencies for
comment. The installation initiated the FS for OU 1. The
installation initiated the remedial designs (RDs) and remedial
actions (RAs) for SIA Soil OU and ASA OU, including
excavation of contaminated soil and installation of land use
controls that provide gravel caps to reduce exposure. The
installation developed a partnership with Jacksonville State
University to compile and analyze data relevant to TCE
concentrations in Coldwater Spring. The installation identified
an additional MMRP site (former buffer zone for open burning
operation). The installation submitted an SI report for the three
MMRP sites.

Anniston AD completed the final SIA Soils OU RD/RA work
plan. The Army completed the RDs and RAs for the ASA OU 3,
and signed the ASA OU 3 ROD with the stakeholders, ADEM
and EPA. The installation completed the draft comprehensive
groundwater FS for OU 1. Anniston AD submitted the draft
technical impractability (TI) waiver report for OU 1 with the final
x€vGf‚eg2PHHS
report to serve as the formal TI waiver application. Anniston AD
collected monthly samples from three locations at Coldwater
Spring.
Regulatory issues delayed the interim groundwater ROD and
the SIA Soils OU ROD.
The installation held quarterly RAB meetings. The RAB
discussed the availability of technical assistance for public
participation contracts.

Anniston AD completed the MMRP SIs, with the sites evaluated
as low priority. Three sites were recommended for RI.
