Bullfrog County, Nevada
Bullfrog County was a short-lived county in the U.S. state of Nevada, created by the Nevada Legislature in 1987. It consisted of an uninhabited 144-square-mile (370 km2) area around Yucca Mountain, completely enclosed by southern Nye County, the county from which it was created. Its county seat was located in Carson City, the state capital—270 miles north. Its creation was ruled in violation of the state constitution in 1989. In compliance with the ruling, the legislature dissolved Bullfrog County and retroceded its territory to Nye County.
The county's establishment was a response to plans by the United States federal government to create a disposal site for radioactive waste in Yucca Mountain. The federal government agreed to provide payment-equal-to taxes (PETT) funding to Nye County during the characterization and construction of the Yucca Mountain repository. This money was intended to go straight to Nye County, bypassing the state government. In response, Nevada Assemblyman Paul May drafted a law declaring the unpopulated area around the proposed nuclear waste site to be a new county, Bullfrog County. Because this new county had no population, any federal payments for placing the nuclear waste site there would go directly to the state treasury. Furthermore, property tax rates in the county were set at 20 percent, the highest allowable by the state constitution. This tax burden (potentially up to $25 million) was meant to discourage the waste site's creation by making it prohibitively expensive to use the land for a radioactive waste dump. However, it also guaranteed that the waste site would at least be profitable for the state government if it were ever built. The bill was passed at 3:45 am on June 18, 1987—near the end of the year's legislative session—and signed into law by Governor Richard Bryan. The bill stipulated that if the repository was not built in the county, it would be dissolved and reincorporated into Nye County.
