Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Energy 1. The Secretary of Energy should direct the Manager of the DOE Richland Operations Office to: (1) incorporate the best current estimates of cooling water leaks into its estimate of total tank leaks; and (2) revise that estimate as additional information becomes available through the tank-by-tank analysis currently being developed.
Closed - Implemented
