The Environmental Restoration Disposal Facility (ERDF) is a large, engineered landfill in the center of the Hanford Site for the disposal of low-level radioactive, hazardous and mixed wastes generated from Hanford cleanup activities. The ERDF consists of 10 large disposal cells over 108 acres with a waste capacity of 21 million tons.
Since operations began in 1996, more than 18.5 million tons of waste have been disposed of at the ERDF.
