The Department of Energy released its framework on Hanford cleanup.

The EPA report and the missed deadlines both set an interesting backdrop for the first visit to the site by the new secretary of energy. Ernest Moniz visited Hanford a little more than a week ago. And it was the day after his visit that workers found it was likely AY-102 is now leaking into the soil.
In a late-night phone call to the governor, the new Secretary of Energy Ernest Moniz announced waste was likely leaking into the soil below a troubled double-shell tank. It was discovered by a crew doing routine maintenance to tank AY-102.
