“……… Rocky Flats Wildlife Refuge is an oasis of prairie biodiversity covering 5,000 acres, home to prairie dogs, elk, monarch butterflies, and rare xeric grasses. It also serves as a buffer zone around the site of the largest completed nuclear cleanup to date in the United States. And David Lucas of the U.S. Fish and Wildlife Service is preparing to open it for public access in summer 2018. He’s reckoning on 150,000 visitors a year.During the Cold War, Rocky Flats was secretly machining plutonium manufactured at Hanford into some 70,000 spheres that formed the explosive heart of each weapon in Uncle Sam’s nuclear arsenal. Plutonium pollution was routine. The plant had nowhere to get rid of the day-to-day plutonium waste, which was often dumped in hastily dug landfills or sprayed onto grassland around the plant. At an outdoor compound known as pad 903, where more than 5,000 drums of waste liquids contaminated with plutonium are stored, there’s been substantial leakage. An internal memo reported that rabbits living on the site were heavily contaminated, especially in their hind feet.
A whistle-blower’s allegations about illegal late-night incineration of plutonium waste at the plant led to an FBI raid in 1989. After that—and with demand for plutonium spheres declining following the end of the Cold War—the government closed the site. A federal grand jury sat for three years to hear testimony from the FBI raid. But two days after the jury approved indictments, the Justice Department struck a deal with Rockwell Automation, the company that managed the plant. The company pleaded guilty to some minor charges, but the FBI evidence and grand jury conclusions were sealed forever.
Today, the land that housed the industrial complex remains behind a sturdy fence under the control of the Department of Energy (DOE). But the large grassland buffer zone that once protected the complex from prying eyes has been released into the care of the Fish and Wildlife Service for public access.
There are two concerns. First that, as I saw on a tour with Lucas, the fenced-off core area hardly looks self-contained. Earth slips have left ugly gashes up to 300 feet wide across a former landfill site that overlooks a creek running through the wildlife refuge. The DOE’s Scott Surovchak concedes that “slumping is very common” after heavy rain. Only constant repairs, it seems, will prevent the landfills and buried contaminated buildings and pipework from being exposed.
The second concern is the safety of the buffer zone itself. Harvey Nichols, a biologist from the University of Colorado, has found that when the plant was operating snow falling nearby was often “hot.” Falling snowflakes captured tiny plutonium particles that evaded the stack filter. Just two days of snowfall could deposit about 14 million particles on every acre of the site. “There must be tens of billions of particles in the soil today,” he told me.
The Environmental Protection Agency has dismissed such concerns. In 2006 it found plutonium levels in soil samples in the buffer zone were within acceptable limits and concluded that the lands comprising the refuge are “suitable for unlimited use and unrestricted exposure.” But Moore, the activist, is unimpressed. “Prairie dogs and other critters will burrow down for several feet and bring plutonium to the surface,” he says. “Children will be exposed to plutonium. And people will start taking plutonium out into their communities on boots and cycle wheels. Why would we allow that?”
Lucas is unmoved. “We need to get people out here on the refuge. Then the fears will evaporate,” he told me. But that is just what worries his opponents. Forgetting about the plutonium is the worst thing that could happen, they say……….This piece is adapted from Pearce’s new book, Fallout: Disasters, Lies, and the Legacy of the Nuclear Age.
