&EPA Northeast Church Rock Mine
Site Update
U.S. Environmental Protection Agency • Region 9 • San Francisco, CA • December 2018
Background
The Northeast Church Rock Mine (NECR) is
a former uranium mine located at the north-
ern end of State Highway 566, approximately
17 miles northeast of Gallup, New Mexico in
the Pinedale Chapter of the Navajo Nation.
United Nuclear Corporation (UNC) oper-
ated the NECR mine from 1967 to 1982.
During mining, approximately 3.5 million
tons of ore was extracted, making it one of
the highest producing uranium mines on the
Navajo Nation. Due to the proximity of resi-
dents to the mine site, this mine was identi-
fied as the highest priority for cleanup by
the U.S. Environmental Protection Agency
(USEPA) and Navajo Nation Environmental
Protection Agency (NNEPA) out of over 500
abandoned uranium mines on the Navajo
Nation.
What Has Been Done?
•	Over 200,000 tons of contaminated soil has been removed from the residential area and brought back to
the mine waste pile.
•	The mine waste pile has been temporarily covered and stabilized until it can be removed.
USEPA, working with the Navajo Nation and the State of New Mexico, has decided to move the waste
to the UNC Mill site.
•	UNC/GE completed a design for the NECR cleanup which has been approved by USEPA.
What is Happening Now?
In September of 2018, UNC/GE (General Electric) submitted a request for a license amendment (which
includes the completed design) to the Nuclear Regulatory Commission (NRC) to build a repostory for the
NECR mine waste at the UNC Mill Site. NRC is currently reviewing the request.

What Will Happen Next?
NRC must approve the request for a license
amendment at the UNC Mill Site before the
NECR Mine Site cleanup construction can
begin. The NRC estimates two to five years for
the required NRC license amendment.
Cleanup construction is anticipated to take
approximately four years to complete.
GE contractors take samples on the Northeast Church
Rock Mine site.
Who is Involved?
•	The company conducting the cleanup is UNC. UNC is owned by General Electric.
•	USEPA oversaw the design with the help of a design review team.
•	The design review team included USEPA, Navajo Nation EPA, State of New Mexico Environmental
Department, the Nuclear Regulatory Commission (NRC) and the U.S. Department of Energy. The team
also included a local resident appointed by the Red Water Pond Road Community Association, who
was assisted by a technical support representative from the Technical Assistance Services for
Communities (TASC) contract administered by USEPA.
