Our Nuclear Waste Program regulates other sites with mixed (radioactive and hazardous chemical) waste in Washington that aren't part of the Hanford cleanup.

US Ecology, Inc.
US Ecology is a disposal facility that is licensed by the state of Washington to receive commercial low-level radioactive waste. Located in the center of the Hanford site, the facility operates on 100 acres of land leased to the state by the federal government.
The US Ecology site is a waste landfill that has been in operation since 1965. Before 1993, the landfill accepted low-level radioactive waste from across the United States. Since that time, the facility has restricted disposal to waste originating in the eight states of the Northwest Interstate Compact (Alaska, Hawaii, Idaho, Montana, Oregon, Utah, Washington, and Wyoming) and the three states of the Rocky Mountain Compact (Colorado, Nevada, and New Mexico). The Washington State Department of Health oversees operations and facility closure.
Model Toxics Control Act study
The older parts of the facility contain chemical waste that was intermingled with radioactive waste before disposal practices were changed. An investigation under the Model Toxics Control Act, Washington’s environmental cleanup law, has been underway since 1999 to study the extent of the site's contamination, and to develop a remedial action to protect people's health and the environment. As we investigate chemical contamination at the site, we're coordinating with the state Department of Health to put a protective cover on older trenches that have been filled and are no longer being used for disposal.
