The Tennessee Valley Authority’s Boone Dam Internal Erosion Remediation Project has been named the 2019 Outstanding Environmental and Engineering Geologic Project by the Association of Environmental and Engineering Geologists.
AEG is a professional association for scientists practicing in the fields of environmental and engineering geology. This award is the highest honor presented by AEG, TVA says, and distinguishes projects based on select criteria, including: application of environmental and engineering geologic principles; advancement of public understanding of geology and engineering geology; protection of the environment; and enhancement of cultural understanding.
The Boone Dam project was specifically noted for its innovative use of georeferenced data, risk-informed decision making, and contributions to the practice of underground construction in dams.
“TVA is honored by this prestigious AEG recognition, and we are extremely proud of our Boone Dam Remediation Project team,” said David Bowling, TVA vice president of River & Resources Stewardship. “This award recognizes the knowledge, skill and execution of the engineering geologists and other team members who have worked together to successfully manage this project.”
Boone Dam, on the South Fork Holston River in Tennessee, required repairs to address seepage under the embankment that was discovered in October 2014. The dam impounds water for an 89-MW powerhouse. The work began in December 2015 and is ongoing, with the cutoff wall being built and anticipated to be complete by mid-2021.
AEG helps promote public understanding of the geosciences and the highest levels of professional practice within engineering geology, environmental geology and allied fields in the geosciences.
TVA is a corporate agency of the U.S. that provides electricity for business customers and local power companies serving nearly 10 million people in parts of seven southeastern states.
