film In the Family (2011). Activism Overall has actively supported a number of environmental causes, primarily those affecting her native East Tennessee. In 1995, she gave an interview on ABC's news show Primetime attacking the paper company Champion International, which had for years been accused by environmentalists of polluting the Pigeon River. Abnormally high levels of dioxins in the river had been traced to the company's plant in Canton, North Carolina, and were believed by environmentalists to be the cause of the relatively high rate of cancer deaths in the area around Hartford, Tennessee. In recent years, Overall has been a vocal critic of Nuclear Fuel Services, which operates a uranium processing complex in Erwin, Tennessee. She has charged that the complex has poor safety standards, pointing to a study released in 2010 that found soil samples along the Nolichucky River contaminated with enriched uranium traced to the complex. Overall has filed numerous petitions with the Nuclear Regulatory Commission, which insists the complex's radiation output levels are safe. In 2002, Overall helped thwart an attempt by Louisiana Energy Services to build a uranium enrichment facility in the Erwin vicinity. The complex, known as the National Enrichment Facility, has since been constructed in New Mexico. In subsequent years, she sought to prevent NFS's implementation of the Blended Low-Enriched Uranium (BLEU) project in Erwin, which will provide fuel for reactors at Tennessee Valley Authority nuclear power plants. In 2014, Overall campaigned against a proposed pipeline that would allow the new U.S. Nitrogen plant in Mosheim to use water from the Nolichucky River. Environmental activists argue that removing water from and discharging the water back into the river will harm the ecosystem downstream from the pipeline, though U.S. Nitrogen insists the pipeline is safe. Overall accused the plant and regulatory agencies that approved the pipeline of lying about how much of the river's water the plant would use. 2012 U.S. Senate primary campaign On April 4, 2012, Overall entered the Democratic primary to become the nominee to oppose Republican incumbent Bob Corker. She stated that she planned to focus on the environment, as well as women's issues, opposing the Senate transportation bill's Blunt Amendment, which would have provided a religious exemption for the Obama Administration's contraception mandate, asking, "Why is my womb attached to a transportation bill?" She criticized various measures introduced in the Tennessee General Assembly, including Stacey Campfield's "Don't Say Gay"
