The Belene Nuclear Power Plant (NPP) in northern Bulgaria was originally proposed in the mid-1980s. The project was cancelled in the 1992, after significant environmentalist campaigning, when it became clear that the seismic risk in the region was unacceptable. Indeed, 120 people had died in an earthquake only 14km from the project site in 1977. There was also concern that the project would not be economically viable.
Sofia, the capital city of Bulgaria, had only one landfill, which was 500 meters from the Suhodol neighborhood. The residents of Suhodol claimed that the landfill polluted the area and was a danger to the health of their children. In 2001, the mayor of Sofia promised to close the landfill by the end of 2004.
