The Naval Computer and Telecommunications Area Master
Station (NCTAMS), Pacific installation operates two facilities on
the island of Oahu, but conducts industrial operations primarily
at the main station and receiver site in Wahiawa and the Naval
Radio Transmitting Facility in Lualualei. The restoration
program has focused on those two facilities, where
maintenance and operation of electrical transformers and
switches have been the primary sources of contamination. The
installation was placed on the NPL in May 1994 because
polychlorinated biphenyl (PCB)-contaminated soil was detected
in work and residential areas. Contamination with metals and
petroleum hydrocarbons also resulted from the station's
operating and maintenance activities. Two Restoration Advisory
Boards were established because the installation consisted of
two primary facilities. The final community relations plan was
completed in FY95.
Thirty sites have been identified at this installation, including 24
CERCLA sites and 5 underground storage tank (UST) sites.
The installation has completed no further action (NFA)
documentation for Site 14 and UST Sites 6 and 22. The
cleanup progress at NCTAMS, Pacific for FY02 through FY05 is
detailed below.
In FY02, the installation completed the draft remedial
investigation (RI) planning documents for Sites 6 and 24. 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 draft work plans for the
removal action at Sites 17, 18, and 20. In addition, the
installation completed the RI fieldwork at Sites 6 and 24. The
ecological risk assessment (ERA) for Sites 1, 2, 5, and 22
continued. The installation drafted verification planning
documents to confirm the Eureka laboratory results at Sites 14
and 15.
In FY04, the installation completed removal actions at Sites 17,
18, and 20. Additionally, the installation completed draft reports
for verification sampling to confirm Eureka laboratory results at
Sites 14 and 15, and completed Step 3a ERA at Sites 1, 2, 5,
and 22.
