The Navajo Nation extends into the states of Utah, Arizona and New Mexico, covering over 27,000 square miles. This area is larger than ten of the fifty states in America.
On May 16, 1988, the Office of Surface Mining (OSMRE) approved the Navajo Abandoned Mine Land Reclamation Program (NAMLRP) and associated Navajo AML Code / Plan. This approval provided authority for the Navajo Nation to use AML funds to reclaim abandoned mines on the Navajo Nation.
