Homestead Air Force Base (AFB) housed the Air Combat<br />
Command 31st Fighter Wing. EPA placed the installation on the<br />
NPL in February 1990 and the Air Force signed a federal facility<br />
agreement (FFA) in March 1991. In July 1993, the BRAC<br />
Commission recommended that Homestead AFB be realigned.<br />
Subsequently, the 31st Fighter Wing was deactivated, and all<br />
other operations except Air Force Reserve activities were<br />
relocated. The 2005 BRAC Commission recommended the<br />
installation for further realignment. Homestead AFB is a<br />
joint-use base that uses both BRAC and Environmental<br />
Restoration Account funds to reach cleanup goals. Sites<br />
identified at the installation include the JP-4 jet fuel leak area, a<br />
landfill, a polychlorinated biphenyls (PCBs) spill area,<br />
underground storage tanks (USTs), aboveground storage<br />
tanks, and oil-water separators. Interim actions have included<br />
removal of USTs and contaminated soil, groundwater extraction<br />
and treatment, and removal of oil-water separators. The<br />
installation formed a Restoration Advisory Board (RAB) in<br />
FY94, which was chartered in FY96. The installation has also<br />
formed a BRAC cleanup team (BCT). In FY03, the installation<br />
completed its first 5-year review.<br />
In FY94, an Environmental Baseline Survey identified more<br />
than 540 potentially contaminated sites. By FY95, 400 sites had<br />
been closed and the remaining sites were consolidated into 5<br />
major fuel areas and 30 operable units (OUs) in FY96. To date,<br />
Records of Decision (RODs) have been signed for OUs 2, 11,<br />
18, 20, 21, 26, 28, 29, 30, and 31. The cleanup progress at<br />
Homestead AFB for FY02 through FY05 is detailed below.<br />
In FY02, the feasibility study and proposed plan for OU 11 and<br />
the remedial actions (RAs) for OUs 20/21, 30, and 31 were<br />
completed. The RA for OU 11 was initiated with the completion<br />
of the remedial design. An evaluation of the groundwater<br />
analytical data at OU 26 showed a cyclical upswing in<br />
contaminant levels that may be tied to seasonal groundwater<br />
levels. This indicated the presence of a continuing source of<br />
solvent contamination. An additional source removal was<br />
undertaken along with the addition of a biomass amendment to<br />
stimulate microbial action. The RAB met quarterly, which<br />
allowed the Air Force and regulators to update the community<br />
on the program's status.<br />

In FY03, the installation completed its first 5-year review and<br />
obtained regulatory concurrence. The Air Force and EPA<br />
signed the ROD for the canal portion of OU 11, which received<br />
concurrence from the State. The installation initiated the RA for<br />
OU 11.<br />
In FY04, the installation completed the canal remediation at OU<br />
11. The sampling schedule for the long-term monitoring sites<br />
was negotiated and OU 22 was moved from the <strong>Installation</strong><br />
Restoration Program (IRP) to the State Petroleum Program.<br />
OUs 11 and 18 were transferred from the Air Force Real<br />
Property Agency (AFRPA) to the Air Force Reserve Command<br />
(AFRC), the 482nd Fighter Wing, and OUs 14, 20/21, 22, 26,<br />
and 28 through OU 31 were separated into their own parcel.<br />
AFRPA conducted an inventory of Military Munitions Response<br />
Program (MMRP) sites. No MMRP sites were identified on the<br />
BRAC portion of the installation.<br />
In FY05, the installation obtained operating properly and<br />
successfully documentation from EPA for OU 26 and updated<br />
the solid waste management unit inventory to reflect current<br />
ownership in preparing for the renewal of the RCRA permit. The<br />
BCT and RAB continued to meet semiannually.<br />

The installation received EPA signature on the ROD for OUs<br />
20/21, 30, and 31. AFRPA transferred the final 24 acres to<br />
Miami-Dade County. AFRPA and EPA signed the ROD for the<br />
terrestrial portion of OU 11, which designated responsibilities<br />
outlined therein to the AFRC. The cost of completing<br />
environmental restoration has changed significantly due to<br />
changes in estimating criteria.<br />
