Cleanup Process |
|
|
|
|
|
From
start to finish, the following process is employed to achieve clean up of the CB/NT
Superfund problem area:
|
|
 |
|
|
• |
|
Define problem areas. |
|
• |
|
Identify all current and historic sources of contamination. |
|
• |
|
Identify all parties whose actions caused the contamination. |
|
• |
|
Control on-going sources of contamination. |
|
• |
|
Investigate methods to clean up each problem site. |
|
• |
|
Determine disposal site/methods for contaminated sediments/soils. |
|
• |
|
Select final clean-up method. |
|
• |
|
Negotiate final action with all responsible parties. |
|
• |
|
Perform site clean-up action. |
|
• |
|
Monitor to verify that remedy has worked and site is not being recontaminated. |
|
• |
|
Remove site from National Priorities List (NPL) - no longer a Superfund site. |

The process started in September 1983 when Commencement Bay was
added to the list of national Superfund sites. Extensive studies to define
the extent of the CB/NT problem area and what methods were appropriate
to clean up Commencement Bay were conducted from 1983 through 1988.
The results of these investigations were incorporated into the site’s Record
of Decision in September 1989 that defined the extent of the problem as well
as what methods would be used to clean-up and dispose of Commencement
Bay’s contaminated mud. To date, 3 clean up actions have been completed:
the St. Paul Waterway in 1988, the Sitcum Waterway in 1994, and Olympic
View in 2002. Work to complete action in the Thea Foss/Wheeler-Osgood
Waterway, Middle Waterway, Hylebos Waterway and ASARCO/Ruston sites
is currently on going.
