EPA takes unprecedented step to remove uranium waste from the Navajo Nation
As a child, herding her grandmother’s sheep, Teracita Keyanna unknowingly wandered onto land contaminated with radioactive waste from three abandoned uranium mine and mill waste sites located near her home on the Navajo Nation.
Keyanna and other Diné citizens have been living with the consequences of uranium mining near the Red Water Pond Road community since the 1960s. But now, uranium waste rock that has sat for decades at a Superfund site will finally be moved to a landfill off tribal land.
“This is a seismic shift in policy for Indigenous communities,” said Eric Jantz, an attorney for the New Mexico Environmental Law Center.
On Jan. 5, in a first-of-its-kind move, the Environmental Protection Agency signed an action memo to transport 1 million cubic yards of low-grade radioactive waste from the Quivira Mining Co. Church Rock Mine to a disposal site at the Red Rock Regional Landfill. The Northwest New Mexico Regional Solid Waste Authority owns and operates the landfill, which is located about 6 miles east of Thoreau, New Mexico.
“I feel like our community has finally had a win,” Keyanna said. She is a member of the Red Water Pond Road Community Association, a grassroots organization made up of Diné families that have been advocating for the waste removal for almost two decades. “It’ll help the community heal.”
“I feel like our community has finally had a win.”
Companies extracted an estimated 30 million tons of uranium ore on or near the Navajo Nation from 1944 to 1986, largely to fuel the federal government’s enormous nuclear arsenal. When the mines were abandoned in the 1980s, the toxic waste remained. Today, there are hundreds of abandoned mines in plain sight on the Navajo Nation, contaminating the water, air and soil. Altogether, there are an estimated 15,000 uranium mines across the West — 1,200 of them on the Navajo Nation alone — with the majority located in the Four Corners region.
The impact of all this mining on Diné communities has been devastating. A 2008 study found uranium contamination in 29 water sources across the Navajo Nation, while other studies show that people living near waste sites face a high risk of kidney failure and various cancers.
At Quivira, the cleanup is set to begin in early 2025 and will continue for six to eight years, according to an EPA news release. The permitting process, which will provide opportunity for public comment, will be overseen by the New Mexico authority that manages the proposed waste site and is responsible for its long-term safety monitoring.
The EPA had considered multiple options for waste remediation. But for years, Red Water Pond Road advocates and other local organizations continually pushed it to simply remove the waste, a course of action that the EPA has never taken before, even though the Navajo Nation has repeatedly called for the federal government to move all uranium waste from Diné tribal land.
Throughout the Navajo Nation, said Jantz, “prior to this decision, EPA’s primary choice in terms of remediation of mine was to bury the piles under some dirt and plant some grass seeds on top, called cap in place.” But studies have shown that this approach is not effective at containing radioactive waste in the long term, he said.
The agency took a similar approach when addressing the other uranium waste in the Church Rock area. In 2013, the EPA and the Nuclear Regulatory Commission, which oversees uranium mine-waste cleanup, dumped 1 million cubic yards of waste from the Northeast Church Rock Mine — a different waste site, roughly 3 miles from the Quivira Mine — on top of existing tailings located half a mile from the Red Water Pond Road communities.
“Prior to this decision, EPA’s primary choice in terms of remediation of mine was to bury the piles under some dirt and plant some grass seeds on top, called cap in place.”
But the EPA plans to handle the Quivira Mine’s waste differently, placing it in geoengineered disposal cells with a groundwater leak protection system after it is moved off-site, an approach that Jantz called “state-of-the-art.”
The Quivira Mine cleanup is part of the 2014 Tronox settlement, which provided $5.15 billion to clean up contaminated sites across the United States. The settlement allocated $1 billion of those funds to clean up 50 uranium mines across the Navajo Nation.
There is a lot more to be done, said Susan Gordon, coordinator for the Multicultural Alliance for a Safe Environment, a grassroots organization led by uranium-impacted communities. Hundreds of abandoned mines pepper the Navajo Nation, and the EPA has not formulated a broader plan to clean up the majority of them. Funding is also an issue, she added.
What the EPA’s decision means for the future of uranium mine waste remediation is unclear. Under other circumstances, Jantz said that the decision would signal a sea change for the EPA’s policy of removing waste from the Navajo Nation. But the incoming Trump administration has not indicated its policy on hazardous waste disposal.
As Jantz put it, “All bets are off.”
