Post Shutdown Decommissioning Activities Report
Revisions to the NRC decommissioning regulations in 1996 introduced the Post Shutdown Decommissioning Activities Report (PSDAR). The PSDAR includes a description of a licensee’s planned decommissioning activities, an estimate of the cost of those activities, and a schedule for their performance.

Decommissioning Environmental Assessment
As a federal agency, the Maritime Administration is required to assess the environmental impacts of its undertakings under the provisions of the National Environmental Policy Act (NEPA), as amended.  This report was prepared for the agency in 2008 and then again in 2018 as part of its decommissioning decision-making process. The Initial EA (2008) analyzed NRC decommissioning options and the Supplemental EA (2018) analyzed the environmental effects of the Decommissioning – License Termination (DECON-LT) project at selected geographic locations. The NRC may incorporate other federal agency environmental analyses in its licensing actions.
