NPL Site Narrative for PCB Warehouse
PCB WAREHOUSE
Saipan, Commonwealth of the Northern Mariana Islands
Federal Register Notice: September 8, 1983Conditions at proposal (October 23, 1981): The PCB Warehouse on Saipan, Commonwealth of the Northern Mariana Islands, is a temporary shelter built to store about 1,400 gallons of transformer fluid containing up to 25,000 parts per million of PCBs. The fluid is stored in drums awaiting shipment or off-site disposal. The storage site is adjacent to the Philippine Sea, an area subject to tropical storms. PCB contamination of drinking water and marine resources used for food is of concern.
This is the top priority site in the Northern Mariana Islands.
Status (September 8, 1983): A remedial investigation of the site conducted by EPA in December 1982 revealed the presence of 21 drums of PCB-contaminated oil and 3 crates of sodium arsenite. Drums were found to be intact, and there was no evidence of any reported spills or leaks. The transformers from which the oil had been drained were at the Saipan Headquarters Building and at the Department of Public Works Yard. There was no indication of leaks or spills near those transformers.
Status (March 7, 1986): In 1984, EPA used CERCLA emergency funds to remove the 21 drums of PCB wastes and 3 crates of sodium arsenite. These were repackaged and transported to the continental United States. The PCB wastes were disposed of at a facility meeting the requirements of the Toxic Substances Control Act. The sodium arsenite was disposed of at a facility permitted under Subtitle C of the Resource Conservation and Recovery Act. Tests confirmed that no PCB wastes had been spilled during the removal action.
This site is being deleted from the NPL because EPA, in consultation with the Commonwealth of the Northern Mariana Islands, has determined that all appropriate Superfund-financed response under CERCLA has been implemented, and that no further response by responsible parties is appropriate.
