New Mexico Forest Preps EIS for Roca Honda Mine Project

Published Date: 9/14/2026

Notice

Summary

The U.S. Department of Agriculture Forest Service (Forest Service), Cibola National Forest & National Grasslands, intends to prepare an environmental impact statement (EIS) to assess and disclose the effects of the proposed Plan of Operations (PoO), also referred to as the Mine Operations and Reclamation Plan (MORP), submitted by Roca Honda Resources, LLC (RHR), for the development and operations of the Roca Honda Mine Project. The Forest Service is the lead agency. The Environmental Protection Agency (EPA) Region 6 and the Bureau of Land Management's (BLM) Rio Puerco Field Office are cooperating federal agencies. This notice announces the beginning of a 30-day comment period to solicit comments and identify issues. The EIS will evaluate potential impacts of the development and operations associated with the proposed underground uranium mine on National Forest System (NFS) and BLM- administered lands, as well as state and private lands. The Forest Service expects that the proposed action will require a project- specific amendment to ensure consistency with the Cibola National Forest Land Management Plan. The Enterprise Land Management System number for the project is 301824 (see link below).

Analyzed Economic Effects

6 provisions identified: 0 benefits, 5 costs, 1 mixed.

Public radon exposure risk

The EIS will evaluate potential exposure of the public to radioactive radon gas vented from mine shafts near the project area in McKinley County, New Mexico. The Forest Service lists radon gas exposure from vented shafts as a specific substantive issue to be evaluated.

Treated wastewater discharged to Rio San Jose

The proposed project would construct a pipeline in the New Mexico Highway 605 right-of-way and discharge treated water into a non-perennial segment of the Rio San Jose in the Village of Milan, New Mexico. EPA must consider an NPDES permit under Clean Water Act section 402 for that discharge.

Land disturbance footprint: 87 + 279 acres

Proposed activities would disturb about 87 acres on National Forest System lands and about 279 acres on State and private lands for wells, shafts, pipelines, roads, a water treatment plant, ore bays, waste rock stockpiles, and ponds. These disturbances occur near San Mateo and Grants in McKinley County, New Mexico.

Long project life: 21 years with 11 years production

The project lifespan is estimated at approximately 21 years, including about 11 years of mineral production and remaining years for construction, reclamation, and closure monitoring. The EIS will evaluate potential effects on local and state workforce and the economy.

Forest Plan amendment affecting tribal and water protections

The Forest Service expects the proposed action will require a project-specific amendment to the Cibola National Forest Land Management Plan to except the project from certain desired conditions related to tribal, cultural, and water resources.

Truck haul of ore to Utah mill

Ore-bearing materials would be hauled off-site by truck to the White Mesa Mill in Blanding, Utah for processing. The proposal therefore includes sustained truck transport off the site for processing outside New Mexico.
