Nuclear Waste Program

From 1945 until 1987, the U.S. had an insatiable need for plutonium to fuel the country's nuclear arsenal. In the quest to maintain nuclear superiority during the Cold War, the federal government emphasized production over environmental protection. Now we're overseeing cleanup of the toxic chemicals and radioactive waste left behind.

As a result of 45 years of plutonium production at Hanford, there are enormous amounts of toxic waste in Washington that we must ensure is safely contained and eliminated whenever possible. The remaining waste at Hanford includes radioactive waste and equipment; dangerous chemicals; contaminated soils; polluted groundwater; and 177 tanks holding 56 million gallons of chemical and radioactive waste.

Plutonium production at Hanford ended in 1987. Cleanup began almost immediately, and Washington state insisted that it have a meaningful part to play. The result was the Tri-Party Agreement, which spells out roles and responsibilities for the U.S. Department of Energy, EPA, and us.

The U.S. Department of Energy directs the cleanup at Hanford. We partner with the EPA to regulate the cleanup. Our mission is to ensure safe, effective cleanup that proceeds on schedule and serves to protect human health and the environment — today and into the future.

Ecology's role

Ecology formed its Nuclear Waste Program to keep people and the environment safe from the dangers of radioactive and chemically hazardous waste. Our program pursues a broad mission:

  • Enforcing regulatory compliance and cleanup at Hanford and other mixed waste facilities statewide, including the Puget Sound Naval Shipyard and Framatome (formerly AREVA NP Inc.).
  • Promoting public involvement to enhance waste management, compliance, and cleanup.
  • Ensuring appropriate oversight to safely manage hazardous waste at the US Ecology low-level radioactive waste disposal site.

A toxic stew of threats

Environmental threats took many forms at Hanford:
Danger: Radiation sign at Hanford site.
  • Originally 80 square miles with contaminated groundwater, some seeping into the Columbia River
  • Millions of tons of contaminated soil
  • Hundreds of contaminated buildings
  • Hundreds of dumping sites for toxic and nuclear waste
  • 177 underground tanks holding toxic stews of nuclear and chemical waste
  • Toxic fumes escaping from the tank waste
  • Nine nuclear reactors

The regulatory framework

Two far-reaching federal laws govern the Hanford cleanup. RCRA, the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), commonly known as the Superfund law.

Each law plays a vital role in the cleanup. RCRA is the primary federal law devoted to proper disposal of hazardous and solid waste. The law seeks to protect the environment and human health, conserve energy and natural resources and cut down on the amount of waste generated. The Superfund law focuses on cleaning up hazardous waste sites as well as accidents, spills, and other emergency releases of pollutants, and contaminants into the environment.

Our permits

We maintain several permits to govern cleanup operations at Hanford, but the primary permit is the Hanford dangerous waste (site-wide) permit. Or, across most of Hanford, known simply as "The Permit." The site-wide permit has been comprehensively revised several times. Currently we're operating with Revision 8C, but we are working toward release of Revision 9.

In addition, we administer individual permits for facilities that handle mixed (radioactive and hazardous chemical) waste in Washington.

Our projects

Public education and involvement

Poster board at presentation about Hanford asking for group responses.

We're dedicated to including you in the effort to clean up Hanford, which involves a range of activities. We hold public meetings and we ask for your comments on changes to the permits that affect Hanford. Then we consider those comments as we make the changes. We're also available to share information about the Hanford cleanup process with your group, your community, or your classroom. Request a speaker today.
