Historically, the St. Juliens Creek Annex has been used since
1849 for storing, loading, assembling, issuing, and receiving
naval ammunition. Contamination resulted from past handling
of, and operations involving, hazardous materials. The initial
assessment study revealed low concentrations of ordnance
materials throughout the facility. An administrative record was
established in FY99. The EPA placed the facility on the NPL in
August 2000, and the Navy signed a federal facility agreement
(FFA) in July 2004. The installation formed a Restoration
Advisory Board in FY00 and completed a community relations
plan (CRP) in FY01.
Fifteen sites and 12 areas of concern (AOCs) have been
identified at this installation. The installation completed a
Record of Decision (ROD) for Site 6 in FY03, Site 4 in FY04,
and Site 3 in FY06. The cleanup progress at St. Juliens Creek
Annex for FY02 through FY05 is detailed below.
In FY02, the installation finalized the engineering evaluation
and cost analysis (EE/CA) and action memorandum for Sites 3
and 6, and the interim remedial action (IRA) was initiated. A site
screening assessment (SSA) closed 14 sites/AOCs. The
ecological risk assessment (ERA) work plan for Sites 3, 4, 5,
and 6 was completed. The Navy completed an inventory of all
Military Munitions Response Program (MMRP) sites. No MMRP
sites were identified at this installation.
In FY03, the installation completed a draft remedial
investigation (RI)/human health risk assessment (HHRA)/ERA
for Site 2, as well as a draft feasibility study for Site 4. The
installation also completed the final RI/HHRA/ERA report for
Sites 3, 4, 5, and 6. St. Juliens Creek Annex completed a draft
work plan for the IRA at Site 3. In addition, the installation
completed a final work plan for the SSA addendum at Site 8
and AOCs 13, 14, and K, and a site inspection (SI) at Sites 19,
21, and AOC 1. A final site-specific work plan and sampling
analysis plan for the basewide groundwater background
investigation report was completed. The final technical
memorandum site delineation/supplemental RI for Site 3 was
completed. The final Site 6 closeout report and Site 3 removal
summary was completed. The master project plan was updated
and finalized. The final ROD for Site 6 was completed. The

installation completed the final work plan for the Blows Creek
baseline ERA (BERA) (Phase I).
In FY04, the installation conducted supplemental investigations
for Sites 2 and 5, and a BERA for Blows Creek. The final
confirmation closeout report and construction closeout report
for the Site 3 IRA were also completed. The installation
completed the RI/HHRA/ERA for Site 2, as well as a final FFA.
Additionally, the background investigation report SSA
addendum for groundwater was completed. A draft Phase II
expanded RI work plan technical memo for Site 2 was
completed, along with a supplemental SI technical memo of
Sites 19 and 21. The installation also completed a final ROD
and remedial decision for Site 4. The installation completed a
final IRA (Phase II) work plan for Site 3 and conducted the
removal action. The final confirmation closeout report and
construction closeout report for the Site 3 IRA (Phase II) were
also completed. The installation completed a draft SSA
addendum at Site 8 and AOCs 13, 14, and K, along with a draft
SI at Sites 8, 19, 21, and AOC 1. The installation also
completed a draft watershed contaminated source document
for the southern branch of the Elizabeth River watershed.
In FY05, the installation conducted a draft expanded RI (ERI)
for Site 2 and completed the final proposed RA plan and draft
ROD for Site 3. It also completed the final specifications, work
plan, basis of design, and construction of the soil cover for Site
4. For Site 5, the installation completed the draft final
RI/HHRA/ERA and the draft EE/CA. The installation completed
the final supplemental SI report and draft EE/CA for Site 19.
The Navy awarded a contract for hot spot removal. The
installation conducted screening site inspection (SSI) and
completed a work plan for additional groundwater delineation
activites at Site 21. It completed the Phase II Blow's Creek
BERA work plan and conducted the field activities. The
installation finalized the watershed contaminated source
document for the Southern Branch of the Elizabeth River
Watershed. The installation implemented engineering controls
at various Installation Restoration Program (IRP) sites. The
Navy developed a draft updated CRP.

St. Juliens Creek Annex completed an RA, RA completion
report, groundwater monitoring plan, and land use control
remedial design at Site 4. The installation completed a draft ERI
for Site 2 and final ERI for Site 5. The installation finalized a
ROD for Site 3. Additionally, the Navy completed a final EE/CA,
action memorandum, IRA, and construction closeout report at
Site 19. The cost of completing environmental restoration has
changed significantly due to technical issues.
Technical issues delayed the field activities for the storm sewer
video survey and repairs. The installation completed a draft SSI
report for Site 21; however, technical issues delayed final
completion. Technical issues also delayed the final RI for Sites
2 and 5, and the treatability study (TS) for Site 2.
