Tobyhanna Army Depot (AD) provides support for
communications and electronics equipment. Environmental
studies at Tobyhanna AD began in FY80. Identified sites
include landfills, a disposal pit, underground storage tanks, burn
areas, drum staging areas, a surface disposal area, a waste
treatment plant, a spill site area, an unexploded ordnance
(UXO) area, and a fire fighting training area. The most
prominent sites are the burn areas and a drum staging area,
which constitute Operable Unit (OU) 1. Contamination at these
sites included volatile organic compounds (VOCs), solvents,
and heavy metals in groundwater; solvents, metals,
polychlorinated biphenyls (PCBs), and petroleum/oil/lubricants
(POLs) in surface water and sediment; and solvents, metals,
PCBs, POLs, and UXO in soil. EPA placed the installation on
the NPL in August 1990. An interagency agreement (IAG) was
signed in September 1990. In 2005, the BRAC Commission
recommended Tobyhanna AD for realignment. During FY95,
the installation formed a Restoration Advisory Board, followed
by a new community relations plan in FY98. In FY99, the
installation completed a closeout document for 18 no further
action sites. The Army completed its first 5-year review in FY02.
Environmental studies identified 65 areas of concern (AOCs)
covering 1,296 acres at the installation; EPA partially delisted
62 of the AOCs from the NPL in FY01. The installation
completed six Records of Decision, including five in FY00. The
cleanup progress at Tobyhanna AD from FY02 through FY05 is
detailed below.
In FY02, the Army completed the installation's first 5-year
review. Five groundwater monitoring wells were installed at
TBAD 067 for quarterly sampling to determine the extent of
tetrachloroethylene (PCE) contamination. The Army completed
the closed, transferred, and transferring (CTT) ranges and sites
inventory, and identified two Military Munitions Response
Program (MMRP) sites. Tobyhanna AD constructed a barbed
wire fence with warning signs around its UXO area, TBAD 055.
In FY03, the installation continued groundwater monitoring at
OUs 1 and 5. The Army initiated an installationwide MMRP site
inspection (SI). The installation provided information regarding
the UXO area and a former machine gun range (TBAD 029) to
Army

the Army Environmental Center for inclusion in the CTT range
inventory.
In FY04, the installation continued groundwater monitoring at
OUs 1 and 5. The installation maintained the UXO fence and
warning signs. The Army performed the SI fieldwork for all
eligible MMRP sites.
In FY05, the installation continued groundwater monitoring at
OUs 1 and 5. The Army issued the final SI MMRP report. The
installation repaired the existing UXO fence at OU 4 and fenced
an additional 45 acres based on the recommendations in the SI
report. The Army continued to control access to OU 4.
