Cancel the "prescribed burn" at Rocky Flats

The Rocky Flats National Wildlife Refuge, managed by U.S. Fish & Wildlife, occupies most of the site of a now-closed nuclear weapons plant. During almost 40 years of production the plant released highly toxic plutonium into the environment. The Superfund cleanup of the site left tiny plutonium particles in the soil. The proposed burn would make particles available to be inhaled, the worst way to be exposed to plutonium.
