3 INTRODUCTION The environmental dredging project on the Hudson River in Upstate New York was one of the largest environmental dredging projects ever undertaken in the United States. The U.S. Environmental Protection Agency ordered dredging in 2002, after 12 years of study and exhaustive opportunities for all interested parties — including residents, interest groups, elected officials and scientists — to weigh in. Following a comprehensive planning and design phase, dredging began in 2009. GE undertook the project, under the supervision of EPA and New York State, and invested $1.7 billion. Dredging was completed in 2015 after six years of round-the-clock work, seven months each year. The vast majority of PCBs – nearly 80 percent — were removed from a 40-mile stretch of river between Fort Edward and Troy, N.Y., an accomplishment EPA hailed as “a historic achievement.”1 Now, in its first comprehensive review of environmental data since the project was completed, EPA said dredging significantly reduced PCB levels and will be protective of human health and the environment.2 Data collected and analyzed since the completion of dredging show PCB levels in water have declined from pre-dredging levels at every location where samples were collected. In the Upper Hudson north of Albany where dredging occurred, PCB levels in water declined as much as 73 percent from pre-dredging levels. South of Albany, where PCB levels were already significantly lower even before dredging, post-dredging PCB levels declined as much as 36 percent. EPA expects these declines to continue.3 amount of PCB mass removed compared to original estimate 2X NEW YORK AREA WHERE DREDGING OCCURRED OVER 2.7 MILLION CUBIC YARDS OF SEDIMENT REMOVED 1 EPA Statement on Hudson River Cleanup, Oct. 1, 2015 2 Proposed Second Five-Year Review Report for Hudson River PCBs Superfund Site, EPA, May 31, 2017, Pg. 8 3 Proposed Second Five-Year Review Report for Hudson River PCBs Superfund Site, EPA, May 31, 2017, Appendix 1, Pg. 4-12
