Navajo nation, n.m. reach settlements over mine spill
ALBUQUERQUE» The Navajo Nation’s Department of Justice announced Wednesday it has settled with mining companies to resolve claims stemming from a
2015 spill that resulted in rivers in three western states being fouled with a bright-yellow plume of arsenic, lead and other heavy metals.
Under the settlement with the Navajo Nation, Sunnyside Gold Corp. — a subsidiary of Canada’s Kinross Gold — will pay the tribe
$10 million.
The spill released 3 million gallons of wastewater from the inactive Gold King Mine in southwestern Colorado. A crew hired by the U.S. Environmental Protection Agency triggered the spill while trying to excavate the mine opening in preparation for a possible cleanup.
The wastewater made its way into the Animas River and eventually down to the San Juan River, setting off a major response by government agencies, the tribe and private groups.
Water utilities were forced to shut down intake valves and farmers stopped drawing from the rivers as the plume moved downstream. The tribe said the toxic water coursed through 200 miles of river on Navajo lands.
The tribe’s claims against the EPA and its contractors remain pending. About 300 individual tribal members also have claims pending as part of a separate lawsuit.
The EPA under the
Obama administration had claimed that water quality quickly returned to pre-spill levels.
But New Mexico officials, tribal leaders and others continued to warn about heavy metals collecting in the sediment and getting stirred up each time rain or snowmelt results in runoff.
The state of New Mexico also confirmed Wednesday that it has reached a settlement with the mining companies. Under that agreement, $10 million will be paid to New Mexico for environmental response costs and lost tax revenue and $1 million will go to Office of the Natural Resources Trustee for injuries to New Mexico’s natural resources.
After the spill, the EPA designated the Gold King and 47 other mining sites in the area a Superfund cleanup district.
