The mission of Hill Air Force Base (AFB) is to provide logistics
support for weapons systems, to host two fighter wings, and to
operate the Utah Test and Training Range (UTTR). EPA placed
the installation on the NPL in July 1987 and the Air Force
signed an interagency agreement (IAG) in April 1991. In 2005,
the BRAC Commission recommended Hill AFB for realignment.
Site types at Hill AFB include disposal pits, landfills, surface
impoundments, underground storage tanks, fire training areas,
firing ranges, discharge and wastewater ponds, a contaminated
building, a munitions dump, and spill sites. Contaminants
include solvents, sulfuric acid, and trichloroethylene (TCE). The
installation formed a Restoration Advisory Board (RAB) in
FY95. The installation conducted 5-year reviews in FY97 and
FY03.
Since FY87, 111 sites have been identified. Forty-two of these
sites have been grouped into 12 operable units (OUs). The
remaining sites have either been closed out or have achieved
response complete (RC). To date, the installation has signed
Records of Decision (RODs) for eight OUs (26 sites). The
cleanup progress at Hill AFB for FY02 through FY05 is detailed
below.
In FY02, the installation completed a remedial action and
closed one site. The installation continued to partner with
regulatory agencies and to foster RAB involvement. The RAB
met quarterly, and held four RAB training meetings and site
tours. RAB members attended two information fairs in affected
communities. Updates were provided to seven different city
councils and regular meetings with State and federal regulators
kept project managers informed and involved.
In FY03, the installation conducted a 5-year review and
installed remedial systems at two sites. In addition, one site
was closed and a feasibility study (FS) was completed for OU
8. Partnering with regulatory agencies and fostering RAB
involvement continued. Four RAB meetings and four RAB
training sessions were held. Regulatory and RAB participation
occurred in numerous community meetings.
In FY04, Hill AFB completed a remedial investigation and an FS
at the two sites composing OU 5 and an engineering
evaluation/cost analysis and removal action at two sites in OU

9. The installation also completed response actions at 32 areas
of concern (AOCs) and closed 7 AOCs. The Air Force
continued to make significant progress towards signing an
innovative cleanup agreement for the UTTR. The base also
developed geospatial-based land use controls, a lease tracking
database, and geographic information system tools to facilitate
data analysis. The installation continued partnering with
regulatory agencies and the RAB. Hill AFB hosted quarterly
RAB meetings, two RAB work group meetings, and five RAB
training tours and site visits. Five public information sessions
and eight presentations to city councils from communities
around the base were conducted.
In FY05, Hill AFB achieved four remedies in place (RIP), three
RCs, closed out one site, and reduced the risk at OU 9. The
installation also completed the study phase for four sites. Other
notable activities included signing a ROD for OU 8, installing a
groundwater extraction well system to prevent further spread of
the plume at OU 8, implementing a bio-polishing technology
test at OU 2, and constructing an in-ground treatment system at
OU 12. The RAB held four quarterly meetings, three working
group meetings, and five training sessions. The installation held
4 public meetings and made 11 presentations to city councils
and planning boards representing cities adjacent to the base.
The Air Force began the preliminary assessments (PAs) for all
identified Military Munitions Response Program (MMRP) sites.

Hill AFB achieved RIP at two sites and RC at 27 AOCs at the
UTTR. The Air Force signed the ROD for OU 5. The installation
implemented a performance-monitoring program to evaluate
and manage remedial system operations to ensure their
effectiveness in meeting remedial cleanup objectives. The Air
Force completed the proposed plan (PP) for OU 9 and
continued progress on the PP for OU 12. Hill AFB successfully
recycled 400 tons of iron BDU practice bombs into material
suitable for use in a permeable reactive barrier to treat
TCE-contaminated groundwater at the base. The cost of
completing environmental restoration has changed significantly
due to changes in estimating criteria.
The RAB held four quarterly meetings, two working group
meetings, and six training sessions. The installation participated
in six city council meetings, held five public meetings, and held
face-to-face meetings with five local city mayors to discuss
cleanup activities affecting surrounding communities.

Hill AFB initiated site inspection (SI) activities at its MMRP
sites.
