Mission

The mission of the Low-Level Radioactive Waste project is to protect the health and safety of the citizens of the Northwest Interstate Compact member states and to provide the most economical management of low level radioactive wastes.

Commercial Low-Level Radioactive Waste Disposal Facility

The Department of Ecology is responsible for ensuring that waste shipped to the commercial low-level waste disposal facility operated by US. Ecology Inc. near Richland,  Washington meets the criteria set by the Northwest Interstate Compact and the State of Washington. Ecology is also responsible for seeing that the conditions of the contract between the State of Washington, the Northwest Interstate Compact and the Rocky Mountain Interstate Compact are met.

Northwest Interstate Compact

In 1980, Congress enacted legislation authorizing states to form interstate compacts and to develop new regional disposal facilities for low-level radioactive waste. This legislation, the Low-Level Radioactive Waste Policy Act of 1980 as amended in 1985 (Low-Level Radioactive Waste Policy Amendments Act of 1985), was the result of efforts on the parts of the governors of the three states with existing commercial low-level radioactive waste (LLRW) disposal facilities (Washington, Nevada, South Carolina - the "sited states") to bring about a more equitable policy of low-level radioactive waste disposal across the nation.

Three years later, Congress ratified the Northwest Interstate Compact on Low-Level Radioactive Waste Management. The guiding policy of the Compact is the protection of the health and safety of the citizens through the cooperative effort of the party states, while providing for the economical management of low-level radioactive wastes within the Compact region. The original seven member states were Alaska, Hawaii, Idaho, Montana, Oregon, Utah, and Washington. The eighth state, Wyoming, joined the Compact in March of 1992.

As allowed by the Policy Act, the Richland, Washington disposal site stopped accepting out-of-region LLRW as of January 1, 1993, except for that volume agreed to in a contract with the Rocky Mountain Compact.

The Department of Ecology provides staff resources in addition to chairing the compact for the State of Washington.
