The money is part of a $5.15 billion settlement that the federal government reached with Anadarko Petroleum Corp. for the cleanup of thousands of long-contaminated sites nationwide. The settlement announced Thursday resolves a legal battle over Tronox Inc., a 2005 spinoff of Kerr-McGee Corp. that Anadarko acquired in 2006.
Kerr-McGee once operated about 50 uranium mines in the Lukachukai Mountains of northeastern Arizona near Cove and a uranium mill in Shiprock. Uranium waste was thrust over the mountainside and carried by rainwater across land used by hikers, anglers, medicine men and Navajo shepherds, said David Taylor, an attorney with the Navajo Nation Department of Justice.
“I have a feeling of just deep appreciation for the Navajo children, who literally are playing in uranium piles today who aren’t going to have to do that in the future,” he said.
But, Taylor added: “The path before us is still monumental. We’ve got a good start now, and I hope we can build on that.”
The more than $1 billion will address about 10 percent of the tribe’s inventory of abandoned uranium mines. About 4 million tons of uranium ore was mined from the reservation from 1944 to 1986. Many families still live among the contamination and fear drinking water polluted by uranium.
Navajo President Ben Shelly said the settlement will ease some concerns about public health.
About $1 billion of the money benefiting the Navajo Nation will be administered by the U.S. Environmental Protection Agency in San Francisco. Of that, nearly $87 million will be set aside specifically for two sites known as the Quivira Mines near Church Rock. The Navajo Nation will receive $43 million separately to address the Shiprock mill, where uranium ore was processed near the San Juan River, the EPA said.
The federal government has been working for years with the Navajo Nation to address the more than 500 abandoned uranium mines on the reservation, but the effort has been hampered by the costs of remediation and the unwillingness of some companies to pay for cleanup of their previous operations.
Jared Blumenfeld, the EPA’s regional administrator in San Francisco, said federal agencies spent about $100 million as part of a five-year cleanup plan. The EPA is drafting a second, five-year plan, but the budget is expected to be much less, he said.
“The mess that’s on the Navajo Nation in terms of abandoned uranium mines should never have been put there, and all of us have been waiting for this day to start to make a big dent in the cleanup,” he said.
The mountainous sites near Cove rarely are visited, but a network of roads established for mining, logging and firewood gathering provide access. Tribal officials say Navajo medicine men gather plants and herbs for prayer and healing purposes from the mountains, and families set up summer camps where sheep graze nearby.
