From October 2017 through March 2018, researchers from Argonne National Laboratory’s Public Affairs Science and Technology (PAST) Fusion Cell conducted a case study on a tunnel collapse that occurred May 9, 2017, at the Hanford Site, a U.S. Department of Energy (DOE) facility near Richland, Washington. The purpose of this study was to collect and analyze data to identify emergency public information best practices and lessons learned from the event. The results and recommendations from this study can be generalized for future practice and implementation of emergency public information and crisis communication across the DOE/NNSA complex.
