up the food chain. The primary
risk to people is the accumu-
lation of PCBs in the body from
eating contaminated fish. PCBs
were banned by the federal gov-
ernment in 1979.
“We’re making great strides
in removing PCBs from this historic and
iconic river,” said Judith A. Enck, EPA
Regional Administrator. “This has been a
particularly productive dredging season,
helping remove a toxic burden from the
river and river communities and creating
local jobs.”
During dredging operations, an ex-
tensive water monitoring program
measures water quality and the amount
of dredged sediment that is being resus-
pended and transported down river.
The 500 parts per trillion federal
standard under the Safe DrinkingWater
Act was not exceeded, as measured at
Waterford,NewYork, the farthest down-
stream monitoring location in the upper
Hudson River.
TheEPAalsoseta limitontheamountof
capping that canoccur to isolate remaining
PCBs. The requirement that capping not
exceed 11% of the total project area con-
tinued to bemet in 2013.
About 6% of the area was capped, not
including those areas where capping was
unavoidable. All of the dredged material
remaining at GE’s dewatering and pro-
cessing facility in Fort Edward is shipped
by train to permittedout-of-state disposal
facilities.
Over thenext fewmonths,theEPAwill
be reviewing and approving technical plans
for the 2014 dredging season, which will
start in spring when the Champlain Canal
opens for the season.
In 2014, dredging will occur in several
areas of the river that are logistically chal-
lenging, including those near dams, shallow
areas in bays and near islands and the
landlocked sectionof the river located be-
tween theThompson IslandDam and Fort
MillerDam.
Added travel timewill also be required
to transport dredged sediment by barge
from the southernmost dredging locations
to thesedimentdewateringandprocessing
facility located on the Champlain Canal in
Fort Edward.
The EPA has worked closely with
the New York State Department of
Environmental Conservation and theNew
York State Department of Health on the
Hudson River cleanup.
