Northeast Church Rock Mine

The Northeast Church Rock Mine (NECR) is a former uranium mine located at the northern end of State Highway 566 approximately 17 miles northeast of Gallup, NM in the Pinedale Chapter of the Navajo Nation. EPA is working with the Navajo Nation Environmental Protection Agency (NNEPA) to oversee cleanup work performed by United Nuclear Corporation (UNC), a company owned by General Electric (GE).

Background

United Nuclear Corporation (UNC) operated NECR from 1967 to 1982. During this time, they extracted approximately 3.5 million tons of ore, making this the second highest producing mine on the Navajo Nation behind the Kermac Mine No. 22 in the Ambrosia Lake Area. While the mine was in operation, the New Mexico Mining and Minerals Division regulated the site. The uranium ore body is located up to 1,800 feet below grade at the NECR Mine Site. Therefore, the mining was conducted over 1,000 feet below the ground surface accessed through two main underground shafts. Other mining features included several vent holes, support buildings, roads and water extraction wells and treatment facilities. Portions of the site are located within an arroyo. Uranium ore from the UNC mine was processed at the adjacent UNC Mill Site, located on private property across Highway 566.

Cleanup Results to Date

To address contamination that had migrated off the NECR Mine Site into the adjacent residential area, EPA, in partnership with NNEPA, has overseen several time-critical actions where UNC removed approximately 200,000 tons of contaminated soil. This soil was brought back to the mine site waste pile which was regraded, covered, and vegetated to stabilize the contamination during the long planning process for the much larger cleanup of approximately 1.4 million tons of contaminated soil on the NECR Mine Site. EPA provides voluntary alternative housing for nearby residents during construction activities.

Current Design Progress

The cleanup plan for NECR includes moving approximately 1.4 million tons of contaminated soil to the nearby UNC Mill Site. This construction activity, including construction of a repository, or holding cell at the UNC/GE Site requires a lot of planning that takes place during the design phase of the project.

A design review team has been formed to coordinate the review process among the various federal, state, and tribal agencies. The design review team consists of EPA Regions 6 and 9, the Nuclear Regulatory Commission, NNEPA, New Mexico Environmental Department (regulatory agencies), and the Department of Energy. The team also includes a representative from the community assisted by a technical support representative from the Technical Assistance Services for Communities contract administered by EPA.

The design of the NECR cleanup was completed in 2018 and approved by USEPA for submission to the Nuclear Regulatory Commission as part of a license amendment request.

Next Steps: Nuclear Regulatory Commission Licensing

After the permanent repository for mine waste from NECR was designed in September 2018, UNC/GE submitted a request (license amendment) to the Nuclear Regulatory Commission (NRC) to build the repository. The NRC issued a Record of Decision (pdf) approving the License Amendment Request (LAR) to place mine waste from the Northeast Church Rock Mine site at the United Nuclear Corp Mill Site on February 15, 2023. The Environmental Impact Statement (EIS) was filed with EPA and published in the Federal Register Notice on January 13, 2023, and the Safety Evaluation Report was published on December 12, 2022.

Community Involvement

The main purpose of engaging community members is to give them the opportunity to become involved in EPA’s activities and also help shape the decisions that are made that affect their community. To further this goal, EPA has developed a Community Involvement Plan which describes the various ongoing outreach activities.

Who Is the Community?

• The NECR mine site is located in the Pinedale Chapter near the border of the Coyote Canyon, Church Rock, and Standing Rock Chapters, in the Eastern Agency of the Navajo Nation. In 2006 it was estimated that approximately 30 families lived within 1.5 miles of the site.
• The nearest community is along the Red Water Pond Road in the Coyote Canyon Chapter, just north of the Navajo Reservation. This community has organized into a non-profit organization, the Red Water Pond Road Community Association, recognized by the Navajo Nation.

EPA Current Community Involvement Activities

• Organizes periodic public meetings at local chapter houses or in Gallup, NM
• Participates in regularly scheduled calls and meetings with the Red Water Pond Road Community Association
• Provides technical assistance to the Red Water Pond Road Community Association through an EPA national contract, Technical Assistance Services for Communities

EPA Past Community Involvement Activities

• Presented with NNEPA and the Red Water Pond Road Community Association representatives to high school classes in Gallup, NM
• Participated in the Eastern Agency Navajo Abandoned Uranium Mine Open House in April 2017
• Distributed a Community Involvement Plan with input from the community in 2017
• Facilitated voluntary alternative housing efforts during construction activities

Partnerships

• Navajo Nation Environmental Protection Agency
• Navajo Nation Abandoned Mine Lands Program
• Nuclear Regulatory Commission
• Department of Energy
• New Mexico Environmental Department
• Red Water Pond Road Community Association
• Others as suggested by community members and local officials

Cleanup Progress Timeline

Northeast Church Rock Mine was operated by United Nuclear Corporation (a company owned by General Electric) from 1967 to 1982. Click on the different years below to learn about recent and upcoming activities.

2000's

• The Navajo Nation requested EPA take the lead for the NECR Cleanup.
• EPA oversaw UNC/GE investigations of the Mine Site and initial time-critical cleanup actions to remove approximately 200,000 tons of contamination found in the residential area.
• EPA completed and put out for public comments the Engineering Evaluation/Cost Analysis.
• EPA decided on a cleanup plan to consolidate the NECR mine waste on the nearby UNC Mill Site.

2014

• UNC/GE completed Pre-Design Studies and Reports
• EPA negotiated an enforcement agreement with GE to complete the Design Work

2015

• EPA and UNC/GE signed the Design enforcement agreement (called Administrative Order on Consent) and began design
• UNC/GE prepared a Design Work Plan

2016-2017

NECR cleanup plan was in design.

2018

UNC/GE finalized the design and submitted a license amendment request to the Nuclear Regulatory Commission.

2023

On February 15, 2023, the Nuclear Regulatory Commission issued a license amendment to United Nuclear Corporation (UNC) authorizing the placement of waste from the Northeast Church Rock mine site at the UNC mill site. The license amendment decision also includes a Record of Decision (pdf) describing the proposal and summarizes the NRC’s environmental impact statement.
