In this dissertation project, I examine the ways in which a grassroots environmental organization, the Upper French Broad Defense Association (UFBDA), was able to contribute knowledge and voice concerns regarding a Tennessee Valley Authority (TVA) proposal between 1961 and 1972. The TVA proposal included a plan for comprehensive water resource development in western North Carolina which would have required in the implementation of 14 dams, flooding of more than 18,000 fertile agricultural acres and displacing 600 families from their ancestral homes. Employing archival research methods, in this dissertation I analyze the UFBDA's everyday rhetorical tactics which contributed to their overall success in preventing the implementation of the TVA project. I situate archival sources alongside contemporary scholarship in democratic practice, environmental rhetoric, rhetorical citizenship, and ethos, as discussed in rhetoric and writing studies. Overall, this dissertation demonstrates the ways in which the UFBDA case study offers a generative model for future environmental controversies, providing specific techniques which can contribute to the success of grassroots organizations mired in environmental controversies and contentious decisions.
