In 1988, Smith was a cofounder of the Oak Ridge Environmental Peace Alliance (OREPA) and the Foundation for Global Sustainability which later spawned the
Tennessee Clean Water Network and Wild South. In 1990, Smith helped publicly document extensive contamination of TVA's
Watts Bar Reservoir with over 75 metric tons of the heavy metal
mercury, and radioactive
cesium and
plutonium from Oak Ridge’s historic operations. Smith ran for political office in 1996, running for
Tennessee’s 2nd congressional district against long time
Republican Jimmy Duncan. A predominantly Republican leaning district, Smith was able to get the second highest percentage of votes of any of Duncan's Democratic opponents with almost 30%. The
Tennessee Valley Authority runs the
Kingston Fossil Plant, a coal-fired power plant near Knoxville, where, in December 2008,
billions of gallons of coal ash were spilled. This was the largest industrial spill in United States history. The toxic sludge covered 300 acres, destroyed three houses, and polluted the Emory and Tennessee rivers. Smith was asked to testify before the
Senate Environment and Public Works committee at a hearing held on January 8, 2009. He testified that "The lack of regulation we have right now is unacceptable, and that is one of the reasons why this accident has happened." He also called for greater oversight of TVA and a better resource planning process. In the November 2016 General Election, Florida had a
solar ballot measure, heavily backed financially by the Florida utilities, which would have restricted the expansion of solar rooftop power. Smith and Floridians for Solar Choice led a grass-roots coalition to ultimately bring down the initiative that had $25 million in utility-company funding behind it. This coalition reached across party lines to join environmentalists,
Tea Party free marketers, solar companies, and elected officials to defeat this proposal. ==Assignments==
