A Tale of Two Phases
|In 2009 dredging began in the Upper Hudson River to remove sediments with PCBs. Read more.|
Phase 1 of the Hudson River dredging project provides a chance to evaluate whether the equipment and methods being used are adequate to meet the project’s cleanup goals. This phase is underway and will continue until the beginning of November. So far, dredging has removed more than 16,000 cubic yards of the river bottom. You can follow the project’s productivity at the following website: www.hudsondredgingdata.com/
That website also provides information about the various types of monitoring being done to ensure the project is performed in a way that is protective of human health and the environment.
The design elements to be scrutinized during Phase 1 include the equipment selected for dredging sediment and transporting dredged materials to the sediment processing facility, PCB resuspension control and monitoring equipment, the processes and equipment used for dewatering and stabilizing the dredged material and for treating water generated during sediment processing, the rail infrastructure designed for transport of processed dredged materials to the final disposal location in Texas, and the methods and equipment used to backfill dredged areas and, in certain areas, to reconstruct habitat. EPA will be watching all of these project components closely.
At the end of Phase 1 dredging and prior to the start of Phase 2 dredging, EPA and an independent scientific panel will separately evaluate the project to determine whether the dredging design or dredging operations should be modified for the final phase. If all goes according to plan the entire project will be complete by November of 2015.
