The Navajo Nation is
a vast land mast of over 26,000 square miles, located within the states of New
Mexico, Arizona, and Utah. The lands vary from the low deserts to the high
mountainous terrain. Weather ranges from the cold winter months to the hot
summers. Mining has a legacy that goes back to the late 1800’s for minerals
such as coal and the early 1900’s for minerals such as uranium, vanadium,
copper, and sand & gravel.

Navajo AML was
successful in obtaining Coal certification in 1994, basically acknowledging the
complete reclamation of all known eligible coal sites. Navajo AML continues to
perform a limited amount of work on coal related problems, problems that are
reported by the community members.
The terrain and
environmental conditions varied widely from the low and dry lands of Cameron,
Arizona to the mountainous, rough, and wetter lands of the Chuska mountain
range.
From the
years 1988 to 1992, NAMLRP initiated an on-the-ground inventory assessment on
Non-Coal related abandoned mine land (AML) sites. Navajo Abandoned Mine Lands
Reclamation Program (NAMLRP) has documented over 1,100 non-coal abandoned mine
lands (AML) sites within the jurisdictional boundaries, Navajo Tribal Trust
Lands.
Navajo AML initiated
reclamation work on Priority 1 non-coal sites in 1989. Since 1989 and following
the process of coal certification, Navajo AML has successfully completed
approximately 90% of the total inventoried non-coal AML sites of 1,085 AML
sites. The non-coal sites include Uranium, Copper and Sand & Gravel mines. The
mine features include both surface mines such as Open Pits, Rimstrips and
Trenches, and underground mines such as portals/adits, incline and vertical
shafts. An in-house Health Physics program is utilized for monitoring
radiation exposure, and for environmental controls during the reclamation of the
uranium mine sites.
