The agency said it worked closely with Navajo Nation to develop contracts that would incentivize the creation of employment opportunities for Navajo residents in order to build local economic and institutional capacity.

The majority of funding for the contracts comes from a nearly $1 billion settlement made in 2015 with Kerr McGee Corp. for the cleanup of more than 50 mines in Nevada and on the Navajo Nation that the company and its successor, tronox, were responsible for.

From the late 1940s through the 1960s, Kerr-McGee mined more than 7 million tons of ore on or near the Navajo Nation, leaving behind uranium mine sites that included contaminated waste rock piles. Exposure to uranium in soil, dust, air, and groundwater, as well as through rock piles and structural materials used for building can pose risks to human health, according to the EPA

Mining stopped for the most part decades ago, and the Navajo Nation banned uranium mining on its lands in 2005. But the cleanup effort has lingered. The EPA launched five-year programs in 2007 and 2014 to study the issue and identify the biggest risks, and the agency last year added abandoned Navajo uranium mines to its list of Superfund sites “targeted for immediate, intense action.”…….  https://www.12news.com/article/news/local/arizona/epa-awards-220-million-for-uranium-mine-cleanup-on-navajo-nation/75-154a0fae-53e3-477d-a5ce-0a678d97d
