Remaining Superfund Process

If you have read the "What's Happening Next?" page, you know that the PRPs must submit a Feasibilty Study to EPA on Nov. 15, 2011.  After the FS is complete, EPA will analyze it and either accept, modify, or reject the FS.  Once EPA is satisfied with a remedy it believes is appropriate, the agency will issue a Record of Decision.  This final decision can be challenged by the PRPs as well as third parties.


But, what happens after a remedy is selected?  Once cleanup begins, what regulatory measures still exist to oversee the cleanup process is done effectively?


Construction Completion


This list maintained by the EPA is neither required by law nor is it legally binding.  However, it allows EPA to simplify the way it tracks sites that are either deleted from the NPL, where physical construction is complete, but cleanup levels have not been met or where response actions require no construction.  For more information on the Construction Completion List (CCL), click here.


Post Construction Completion


According to the EPA, "The goal of Post Construction Completion activities is to ensure that Superfund response actions provide for the long-term protection of human health and the environment. EPA's Post Construction Completion activities also involve optimizing remedies to increase effectiveness and/or reduce cost without sacrificing long-term protection of human health and the environment." 1

Performance Measures


EPA operates various programs to track the status and success of Superfund sites across the nation.  These programs are called Performance Measures, and help the agency in future decision-making contexts.


Deletion from NPL


EPA can delete a site from the NPL if there is no threat to human health and the environment.  This can happen a few ways such as responsible parties implement all appropriate response actions or the Remedial Investigation/Feasibility Study show that there is no need to implement response actions.  In the case of Portland Harbor, it is likely that response actions will be required to remediate the identified COCs-- PCBs, DDx, Dioxins/furans, and PAHs.

Ultimately, cleaned up sites that no longer pose a threat to human health and the environment should be reused.  The stigma of a superfund site is strong, so efforts are needed to redevelop these previously contaminated areas.  Twelve years ago EPA launched its Superfund Redevelopment Initiative.
