MARLBORO — A public information session to discuss the initiation of construction activities at the Burnt Fly Bog federal Superfund site will be held June 5 from 4-8:30 p.m. at the municipal courtroom in Town Hall, 1979 Township Drive.
The state Department of Environmen-tal Protection (DEP) and the U.S. Environmental Protection Agency recently awarded a $10.7 million contract to Shaw Environmental and Infrastructure Inc., Trenton, to remove approximately 25,000 cubic yards of PCB- and lead-contaminated soil from the Burn Fly Bog site, according to a press release.
Representatives from DEP and Shaw Environmental will be available to discuss and answer questions on the upcoming construction project to excavate and dispose of contaminated soil from the northerly wetlands and tar patch areas of the site. The excavation and disposal portion of this cleanup is expected to take four months to complete.
Approximately 6 acres of wetlands in these areas will then be restored or reconstructed. Long-term biological monitoring for the westerly wetlands will also occur.
The Burnt Fly Bog site is off Tyler’s Lane. The site is 1,700 acres, of which approximately 60 were contaminated.
According to a press release from the DEP, waste oil stored in earthen lagoons in the uplands area would periodically overflow into the adjacent wetlands, causing contamination. The uplands area of the site, which consisted of four lagoons, has been remediated. The lagoons were excavated and the contaminants were disposed of off site.
The other contaminated areas are known as the northerly wetlands, the tar patch, and the westerly wetlands. A sedimentation basin was constructed in 1996 to ensure that any contamination from the northerly and westerly wetlands areas would be captured prior to leaving the site, thus protecting the Deep Run and the Runyon well field that serves Perth Amboy.
A record of decision issued in 1998 called for no action in the westerly wetlands with long-term biological monitoring. It also stated that the northerly wetlands and the tar patch were to be remediated.
