The 1995 BRAC Commission recommended closure of
Oakland Army Base. The Army closed the installation as
scheduled on September 30, 1999. Beginning in 1989, the
installation continued to characterize potentially contaminated
areas through its Installation Restoration Program (IRP). These
sites included underground storage tanks; Berths 6 and 6 ½,
where storm drain bedding materials were contaminated with oil
and fuel products; Building 991, where pesticides and oil were
in soil and groundwater; the West Grand Avenue overpass
roadsides (lead-contaminated soil); Building 807 (chlorinated
solvents in soil and groundwater); and Building 648, where soil
was contaminated with polychlorinated biphenyls (PCBs). In
FY96, the installation formed a BRAC cleanup team and a
Restoration Advisory Board (RAB). In FY98, the installation
completed an initial BRAC cleanup plan and an Environmental
Baseline Survey for each of the base's 26 parcels.
Environmental studies identified 26 BRAC parcels at the
installation. To date, the Army has signed a Record of Decision
(ROD) and transferred approximately 387 acres. Parcel 1 and
Operable Unit (OU) 2 are the only remaining Army sites. The
cleanup progress at Oakland Army Base for FY02 through
FY05 is detailed below.
In FY02, under negotiations for a finding of suitability for early
transfer (FOSET), the state regulatory agency agreed on land
use controls to be included in the transfer documents. In
addition, EPA granted a land disposal restriction variance,
which greatly facilitated the agreement by the state regulatory
agency to accept the viability of the financial agreement
between the Army and the local reuse authority (LRA). The
Army postponed groundwater treatment of the MTBE and
benzene plume, which the LRA assumed upon transfer. The
Army transferred 18 acres to the Federal Highway
Administration. The Army awarded a remedial
investigation/feasibility study (RI/FS) contract for the remaining
20-acre Parcel 1. 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 no Military Munitions
Response Program (MMRP) sites at this installation. The RAB
reviewed the investigation reports for the Building 1 waste oil
site, the OU 4 investigation, and the Phase II investigation as

well as the LRA's remedial action (RA) plan and risk
management plan.
In FY03, the Army provided supplementary groundwater
monitoring, thus completing FOSET negotiations. Funding was
programmed for the Parcel 1 investigation and cleanup. The
Army also initiated off-site OU 2 groundwater monitoring. In
support of the FOSET, the state regulatory agency issued a
ROD approving the LRA RA and risk management plans. The
installation transferred 366 acres to the LRA. The RAB initiated
the process to formally adjourn.
In FY04, the Army transferred groundwater monitoring
responsibility to the LRA for their closure actions. The Army
continued to oversee LRA cleanup actions under the terms of
the environmental services cooperative agreement (ESCA).
In FY05, the Army completed the Parcel 1 RI and draft FS, and
began remedial design (RD)/RA contracting actions. The
regulators agreed to postpone RAs at OU 2 until the source
area for the contamination was investigated and remediated.
The installation continued oversight of the LRA RAs.

The Army completed the FS and awarded a contract for RD/RA
at Parcel 1. The Army also drafted the decision document (DD)
for Parcel 1 RAs. The Army reevaluated the alternative selected
in the ROD for Parcel 1. As a result, the Army will amend the
draft DD and resubmit it for regulatory concurrence. The OU 2
property owner started actions to fill the wetland site for railroad
expansion under the fill and development plan. The adjacent
LRA property became a non-issue as a source. The Army
expects that this will relieve the it of RA responsibility at OU 2.
The Army continued oversight of LRA RAs. The cost of
completing environmental restoration has changed significantly
due to technical issues.

The Army has identified no MMRP sites at this installation.
