Wood and PCB removal from the Hudson River

Here is the link to a more detailed article http://www.poststar.com/articles/2009/05/23/news/local/doc4a18542498a77677730303.txt

Dredging has commenced on the Hudson River. Although the dredging is specifically designed for the removal of PCBs and other contaminants on the river's bottom, a secondary impact is very significant; the removal of wood so that the large dredging barges can make it up the river unhindered.

That is a pretty big catch.

I wonder...
1) How successful the PCB removal will be?
2) Won't PCBs still enter the system?
3) Is the EPA going to require the replacement of all of the stumps and logs removed?

We will see.
