Elmendorf Air Force Base (AFB) serves as headquarters to the
Alaskan Command. EPA placed the base on the NPL in August
1990 and the Air Force signed a federal facility agreement
(FFA) in 1991. In 2005, the BRAC Commission recommended
Elmendorf AFB for realignment. Sites include old construction
landfills, petroleum spill sites, and underground storage tanks.
The installation formed a Restoration Advisory Board (RAB) in
FY92. In FY97, the RAB charter was rewritten to focus on all
environmental activities, beginning the transition to a
Community Advisory Board. The installation developed a
community relations plan, which was revised in FY00. A 5-year
review was conducted in FY98 and again in FY04.
Eighty-eight sites have been identified at this installation.
Thirty-eight sites, grouped into six operable units (OUs), are
covered by the FFA. An additional 42 sites have been
designated as petroleum/oil/lubricant (POL)-contaminated
sources and remedial activities are being performed under the
State of Alaska cleanup regulations. The remaining eight sites
are not part of either the FFA or the agreement with the State of
Alaska. By 1997, Records of Decision (RODs) had been signed
for OUs 1, 2, 3, 4, 5, and 6. The cleanup progress at Elmendorf
AFB for FY02 through FY05 is detailed below.
In FY02, the installation continued remedial action-operations
(RA-O) of 21 bioventing systems, the engineered wetland
system at OU 5, and the high-vacuum extraction (HVE) system
at Site SD 15. The annual beach sweep at Landfill (LF) 04 was
conducted. A remedial process optimization (RPO) for the
basewide groundwater program was completed, and resulted in
a reduction in sampling frequency for a majority of the base's
wells. A remedial investigation and feasibility study (RI/FS) was
initiated for Site DP 98.
In FY03, the Air Force began the engineering evaluation and
cost analysis at Site SA 99, which resulted in a no further action
determination. RA-O of 20 bioventing systems, operation of the
engineered wetland system at OU 5, and operation of the HVE
system at Site SD 15 continued. The installation also conducted
the annual beach sweep at LF 04. Elmendorf AFB received
Pacific Air Forces' (PACAF's) General Thomas D. White
Installation award.

In FY04, Elmendorf AFB completed the second 5-year review.
The installation also completed and signed the ROD for Site DP
98 and the site closure report for LFs 05, 07, and 13, and Site
OT 56. In addition, the installation initiated the RA for Site DP
98 and system optimization of the OU 5 engineered wetland
remediation system, as well as the removal action at Site SS
83. Elmendorf AFB received PACAF's General Thomas D.
White Installation award.
In FY05, Elmendorf AFB began the OU 6 explanation of
significant differences (ESD) at Site SD 15. The ESD provides
clarifications to the criteria used to operate the SD 15 HVE
treatment system, administration of land use controls, and use
of a State-mandated cleanup goal for 1,1,2,2-Tetrachloroethane
at LF 02. The installation also completed and signed site
closure documents for Sites ST 71, ST 74, and SA 99. In
addition, the Site DP 98 limited source removal was completed,
annual beach sweeps at LF 04 were conducted, and PACAF's
first performance-based contract was accomplished at Site PL
81. An RPO project was conducted that resulted in
implementing two separate groundwater plume treatability
studies (TSs) to enhance the cleanup process at these two
locations within the base boundaries. The installation received
both PACAF's General Thomas D. White Installation and Team
awards. The Air Force began preliminary assessments (PAs)
for all identified Military Munitions Response Program (MMRP)
sites.

Elmendorf AFB began a TS for enhanced bioremediation at the
Kenney Plume (Site ST 37) and began a TS for a bio-reactive
barrier at the Slammer Plume (Site ST 37). The installation
prepared draft decision documents (DDs) for Sites ST 36/66,
SS 43, and ST 68. The installation completed a site closure
report for Site SS 10. The Air Force also conducted annual
beach sweeps at LF 04 and continued operation of bioventing
systems at Sites FT 23 and ST 32. The cost of completing
environmental restoration has changed significantly due to
changes in estimating criteria.
Elmendorf AFB conducted additional sampling at Site ST 61;
however, technical issues delayed DDs.

The Air Force continued the PAs at all identified sites. Cost
estimates were updated and the initial Munitions Response Site
Prioritization Protocol rating for each MMRP site was
developed.
