9 When GE signed the agreement to conduct EPA’s selected dredging remedy, Scenic Hudson’s Ned Sullivan said, “I think it’s a very important turning point for the Hudson River.”8 MORE PCBs REMOVED THAN ANTICIPATED EPA recognized that the data on PCBs in the river was incomplete when it selected the dredging project in 2002, and it ordered a comprehensive sampling program to help delineate the areas to be dredged. More than 50,000 sediment samples have been collected in the river between Fort Edward and Troy. The sampling results showed more PCBs than EPA initially estimated. Because EPA’s decision required the removal of sediments that exceeded an established level (rather than a fixed volume), dredging ultimately removed more than twice the mass of PCBs than the Record of Decision required. The 2002 Record of Decision estimated the removal of “approximately 2.65 million cubic yards of PCB-contaminated sediment … which is estimated to contain 70,000 kg (about 150,000 lbs) of total PCBs (approximately 65 percent of the total PCB mass present in the Upper Hudson River).”9 EPA’s most recent Five Year Review notes that 155,800 kg of total PCBs were removed from the river.10 The estimated amount of PCBs remaining in the river is in line with EPA’s Record of Decision projection. Because more PCBs were removed than initially expected, nearly 80 percent of the total PCB mass in the Upper Hudson was removed.11 8 WAMC radio broadcast interview, April 10, 2002 9 Hudson River PCBs Site New York Record of Decision, EPA, February 2002, Pg. 94 10 Proposed Second Five-Year Review Report for Hudson River PCBs Superfund Site, EPA, May 31, 2017, Pg. 4 11 Data based on 2017 analysis by GE science consultant Anchor QEA
