Energy Northwest submitted a site restoration plan for its terminated nuclear power plant projects in March 1995 to the Washington State Energy Facility Site Evaluation Council (EFSEC). EFSEC conditioned its approval of the plan on conducting more detailed reviews as additional information became available and Energy Northwest finalized its plans. Since 1995, information on the costs of various restoration options has been improved. Mom recently, there has also been interest in redevelopment of the Projects 1 and 4 site for the benefit of the local economy.

This revised Restoration Plan for the Projects 1 and 4 site provides a discussion of the economic factors regarding the costs and benefits of various restoration options versus the relative public risk. Nine levels of restoration ranging from the minimum - securing and protecting the site from public access, to complete restoration are given. To evaluate the restoration alternatives, this Plan assesses safety and health, environmental and regulatory factors in light of the estimated cost of each alternative, Other factors that affect the selection are also discussed.

This Plan provides a recommended long-term level of restoration contingent on the site not being used for economic redevelopment. Energy Northwest plans to follow a parallel path until a decision is made on the site's reuse. This decision is expected within the next 12 to 18 months. To avoid any further delay, pending the necessary approvals, Energy Northwest is preparing to begin restoration activities this year.

In the absence of redevelopment, this Plan recommends that the remaining major concrete structures be permanently sealed or removed. At Project 4 all remaining structures would be reduced to 25 feet above grade. At Project 1 the turbine generator building would be removed but the containment dome remains. Other Project 1 concrete structures would be permanently sealed. The turbine pedestals at both sites would remain.

Energy Northwest's approach is to commence with restoration activities at both sites that need to be addressed regardless of the redevelopment decision. The specific tasks planned for 18 months beginning in July 1999 are given in this Plan. Once the economic development potential is known remaining restoration activities will begin in earnest.
