The Integrated Disposal Facility (IDF) is an engineered disposal site at the center of the Hanford Site. It is designed to receive immobilized low-activity waste from the Waste Treatment and Immobilization Plant and other low-level waste from Hanford Site operations.

The IDF is designed similar to Hanford’s Environmental Restoration Disposal Facility. It currently includes two disposal areas called cells but can be expanded as needed to a total capacity of six cells. The cells are engineered to protect the groundwater. Workers will monitor, collect and treat leachate (water from rain, snow and dust suppression) that reaches the liner at the bottom of the facility.
