"SALT LAKE CITY — The U.S. Environmental Protection Agency has awarded three contracts for the clean-up of more than 50 abandoned uranium mine sites on the Navajo Nation, worth up to $220 million over the next five years.
The majority of the funding comes from the $1 billion Tronox settlement in 2015. According to the EPA, work is scheduled to begin later this year following the completion of assessments in coordination with the Navajo Nation Environmental Protection Agency. A news release stated that the cleanup sites are in New Mexico’s Grants Mining District and in 10 chapters located on the Navajo Nation, which was the primary focus of uranium extraction and production activities for several decades beginning in the 1950s."
