Duwamish Update February 2007 EPA is experimenting with new ways to get information out to anyone interested in the Superfund investigation and cleanup activities in the Lower Duwamish Waterway. These periodic e-mail updates will provide announcements and reminders about upcoming meetings or reports. If you have suggestions on how to make these updates more useful to you, contact Renee Dagseth at 206-553-1889 or dagseth. renee@epa. gov. You are receiving this e-mail because you asked to be on EPA's list to receive e- mail updates on Lower Duwamish Waterway cleanup work. Please feel free to forward it to anyone who has an interest in the Duwamish. If you did not receive this e-mail directly from EPA and would like to be added to our e-mail list for future updates, or if you would like to be removed from this list, please contact Renee. Please check our Duwamish website which is being updated regularly. http://vosemite.epa.gov/r10/cleanup.nsf/sites/lduwamish. Lower Duwamish Remedial Investigation/Feasibility Study: The Lower Duwamish Waterway Group (LDWG) has prepared a report showing results of a February 2006 subsurface sediment sampling. The sampling report is available at http://www.ldwg.org/rifs docs4.htm#subsurfsed and EPA's Duwamish website (see above). This report is part of the Remedial Investigation and will be used to determine the nature and extent of chemical contamination at depth. This report will feed into the Feasibility Study. (EPA contact: Allison Hiltner, 206-553-2140 or hiltner.allison@epa.gov.) Slip 4 Early Action area: On February 9, 2006, the City of Seattle submitted final (100%) design documents for the Slip 4 sediment cleanup. EPA expects to complete its review of these documents and place them on EPA's Duwamish website (see above) in March 2007. However, on January 31, 2007, Ecology provided a letter to EPA indicating that there are polychlorinated biphenyls (PCBs) in storm drains in an area leased by The Boeing Company at the north end of the King County International Airport. Ecology plans to do further work in this area. Due to the uncertainties regarding the potential for these PCBs to recontaminate Slip 4 sediments, Ecology has recommended that the Slip 4 sediment cleanup be delayed. As a result of Ecology's recommendation, cleanup of this site, which was scheduled for fall 2007, likely will be delayed. EPA will issue a formal decision after reviewing written documentation from Ecology. (Contact: Karen Keeley, 206-553-2141 or keelev.karen@epa.gov ) Boeing Plant 2 Duwamish Sediment Other Area (DSOA) area. Shawn Blocker has taken over from Howard Orlean as the EPA manager for the Boeing Plant 2 cleanup under the Resource Conservation and Recovery Act (RCRA). ------- (Contact: Shawn Blocker, 206-553-4166 or blocker.shawn@epa.gov) If you are looking for information on dredging in the Duwamish: Below is the link to the U.S. Army Corps of Engineers' webpage for regulatory (permits) public notices. In general, only those actions requiring a Corps' Section 10 and/or Section 404 permit from the Corps' regulatory department will be posted to the public notices page. Public notices will include all proposed permit actions, including but not limited to, dredging, piling replacement or other work in the Lower Duwamish Waterway, Harbor Island Waterways (i.e. East Waterway) and in other Washington waterways and wetlands. Visitors to this site will need to carefully review the list of notices to see if there is any proposed work of interest in the Lower Duwamish Waterway or Harbor Island Waterways. www.nws.usace.army.mil/PublicMenu/Menu.cfm?sitename=REG&pagename=Public _Notices Actions which do not require permits from the Corps, such as navigational maintenance dredging by the Corps, will not be posted on this webpage. Corps navigation projects will generally have a separate public notice process, which may include posting notice of proposed work on the Corps' main "news" page which can be found by visiting www.nws.usace.army.mil. ------- |
