The former Naval Facilities on Vieques consist of the former
Naval Ammunition Support Detachment (NASD) on the western
end of the island and the former Vieques Naval Training Range
(VNTR) on the eastern half. Site types include underground
storage tanks, open burning/open detonation areas, and
munitions areas. In FY03, the Governor of Puerto Rico
requested EPA list the former NASD and VNTR on the NPL;
the installation was listed in February 2005. The installation
converted the technical review committee (TRC) to a
Restoration Advisory Board (RAB) in FY04.
The Navy has identified 17 potentially contaminated sites at the
former NASD. At the former VNTR, the Navy identified 12
RCRA sites and 62 potential Military Munitions Response
Program (MMRP) sites. The Navy has transferred 8,114 acres
of the former NASD to the Department of the Interior (DOI), the
Municipality of Vieques, and the Puerto Rico Conservation
Trust. Four thousand of these acres are managed as a
National Wildlife Refuge by the U.S. Fish and Wildlife Service
(FWS). The Navy has also transferred 14,573 acres of the
former VNTR to DOI to be operated and managed as a
National Wildlife Refuge and Wilderness Area. The cleanup
progress at Naval Facilities on Vieques for FY02 through FY05
is detailed below.
In FY02, the Navy completed the final report on background
contamination for the former NASD.
In FY03, the Navy completed a remedial investigation and
feasibility study (RI/FS) at four sites at the former NASD, and
the final baseline groundwater work plan for the former VNTR.
In addition, the Navy completed the munitions investigation and
report for Red and Blue Beach, and placed warning signs in
restricted areas throughout the former VNTR.
In FY04, the Navy conducted Phase I fieldwork for the RI for 12
sites on the former VNTR, RI/FS reports for four sites at the
former NASD, RI/FS investigations for two sites, and finalized
the no further action (NFA) document for nine sites on the
former NASD. The TRC was converted to an RAB. The
installation completed a draft final expanded range assessment
and site inspection (SI) work plan, and submitted the SI work
plan for regulatory review.

In FY05, the Navy completed supplemental RI work plans for
three former NASD sites (Areas of Concern [AOCs] E, I, and R)
and received regulatory approval. In addition, the Navy
submitted engineering evaluation and cost analyses for four
former NASD sites (AOCs J and R, Solid Waste Management
Units [SWMUs] 6, and 7). For the former VNTR, the Navy
completed a preliminary assessment (PA)/SI work plan for eight
photo-identified/potential AOC (PI/PAOC) sites and received
regulatory approval. The Navy submitted a data summary
report for the original 12 RCRA sites. The Navy also completed
a background soil investigation work plan for the former VNTR
and received regulatory approval. The Navy initiated MMRP
interim removal action at SWMU 4 for the former NASD. The
installation conducted an MMRP SI and expanded range
assessment for the former VNTR. In addition, the Navy
conducted an MMRP surface removal action at discrete sites in
the former live impact area (LIA) and specific beaches and
roads at the former VNTR. The Navy completed a charter for
the RAB.
p‰HT2s‚€2€�������
The Navy conducted RI/supplemental RIs at three former
NASD sites (AOCs E, I, and R). The Navy also initiated a
background soil investigation and PA/SI at eight PI/PAOC sites
at the former VNTR. The cost of completing environmental
restoration has changed significantly due to technical issues.
Technical issues delayed the removal actions at four former
NASD sites (AOCs J, R, SWMUs 6, and 7). The installation
completed a draft final work plan for RI at the former NASD
SWMU 4; however, regulatory issues delayed the final RI.
p‰HT2ww‚€2€�������
The Navy completed a time-critical removal action surface
removal of munitions and explosives of concern (MEC) from
200 acres of the approximately 900 acres on the LIA. The Navy
completed the work plan for the Phase II SI and expanded
range assessment.
Technical issues delayed the Phase II MMRP interim removal
action at former NASD SWMU 4. Regulatory issues delayed the
subsurface removal of MEC at selected beaches to be utilized
by DOI and FWS.
