A Navajo tribal company has reached an agreement that would allow the federal government to enforce environmental laws at two coal mines in Wyoming and one in Montana.


The new owner of two Wyoming coal mines has reached an agreement to pay $44 million in local taxes. 


A Navajo Nation company says it will retain 1,200 employees at three coal mines in Wyoming and Montana that it bought through a bankruptcy auction. The announcement Thursday came a day after a federal judge gave final approval for the transfer of the mines from bankrupt Cloud Peak Energy to the Navajo Transitional Energy Company.


Montana environmental officials are proposing approval of a major expansion of the state's largest coal mine after it was recently sold through a bankruptcy auction to a Navajo company.
