The Portsmouth Naval Shipyard (NSY) maintains, repairs, and
overhauls nuclear submarines. A preliminary assessment (PA)
and site inspection identified four potentially contaminated sites.
A RCRA facility assessment in FY86 identified 28 solid waste
management units (SWMUs). Site types at the installation
include a landfill, a salvage and storage area, and waste oil
tanks. In FY92, the installation completed a RCRA facility
investigation. The installation formed a technical review
committee in FY87, which was converted to a Restoration
Advisory Board in FY95. Portsmouth NSY developed a
community relations plan, which was updated in FY97. The
installation was placed on the NPL in May 1994, because of
groundwater contamination at sites on the island, and because
past activities may have adversely impacted sensitive wetland
communities around and downstream of the facility. In 2005,
the BRAC Commission recommended Portsmouth NSY for
realignment. The installation signed a federal facility agreement
(FFA) in 1999.
Portsmouth NSY has identified 35 sites. The installation
completed and signed a no further action document for SWMUs
12, 13, 16, and 23. The installation completed one Record of
Decision. The cleanup progress at Portsmouth NSY for FY02
through FY05 is detailed below.
In FY02, the installation completed interim remediation goals for
Operable Unit (OU) 4, and the work plan and fieldwork for the
Site 10 additional investigation. Portsmouth NSY also initiated
the work plan for Site 31 (Topeka Pier) and began remedial
action (RA) for OU 3. The RA for OU 3 started earlier to
consolidate a portion of the landfill. The Navy completed an
inventory of all Military Munitions Response Program (MMRP)
sites. One MMRP site was identified at this installation.
In FY03, the installation completed the Site 10 additional
investigation report and construction of the OU 3 wetlands. In
addition, the installation completed the remedial design for OU
3. Portsmouth NSY also completed the remedial investigation
(RI) work plan for Site 32. A site visit for the PA was performed.
In FY04, Portsmouth NSY completed the Phase I RI data
package for Site 32 as well as the engineering evaluation and
cost analysis for Site 30. The installation also started the Site
