Phase 1 Evaluation
After completing the first phase of dredging PCB-contaminated sediment in the upper Hudson River, EPA released a detailed technical assessment of the work to a panel of independent scientific experts for their review. The EPA report detailed the effectiveness of the first phase of dredging, as well as the challenges encountered during the first dredging season. It also laid out the Agency's proposed modifications to the engineering performance standards for dredging resuspension, residuals, and productivity for the second phase of the project.
The panel was asked to consider certain questions relating to the engineering performance standards and the monitoring program for Phase 2 of the project. EPA’s report included the New York State Department of Environmental Conservation’s observations and recommendations as an appendix.
The peer review panel publicly discussed its views on the EPA and GE reports in early May 2010 and the members' individual views on the questions were compiled into a report. The Draft Hudson River Peer Review Report underwent factual review by EPA and GE and was provided to the public for informational purposes in mid-August 2010. EPA received the Final Hudson River Peer Review Report in September 2010. The peer review reports are available on this page in the blue box to the upper right and at www.epa.gov/hudson.
During the independent peer review, EPA also sought public comments on the EPA and GE reports. EPA accepted public comment on the Phase 1 Evaluation Reports until April 26, 2010. In response to requests from the public, EPA provided additional time for the public to submit comments on the Addendum to EPA's report. Public comments on the Addendum were accepted until May 17, 2010. These comments were provided to the panel members for consideration during their evaluation.
In December 2010, EPA issued performance standards for Phase 2 dredging based on the knowledge gained during Phase 1 and input from the peer review panel. Phase 2 dredging began June 6, 2011.
