What Is the Construction Completion List (CCL)?
EPA also has developed an NPL construction completion list (“CCL”) to simplify its system of categorizing sites and to better communicate the successful completion of cleanup activities (58 FR 12142, March 2, 1993). Inclusion of a site on the CCL has no legal significance. Sites qualify for the CCL when: • Any necessary physical construction is complete, whether or not final cleanup levels or other requirements have been achieved; • EPA has determined that the response action should be limited to measures that do not involve construction (e.g., institutional controls); or • The site qualifies for deletion from the NPL. In addition to the 142 sites that have been deleted from the NPL because they have been cleaned up (7 sites have been deleted based on deferral to other authorities and are not considered cleaned up), an additional 305 sites are also on the NPL CCL. Thus, as of September 1997, the CCL consists of 447 sites.
