Wyoming Hydro Project Needs More Paperwork and Your Two Cents
Published Date: 9/16/2026
Notice
Summary
Black Canyon Hydro’s Seminoe Pumped Storage Project in Wyoming needs more environmental review before moving forward. The Bureau of Land Management and Federal Energy Regulatory Commission are teaming up to update the environmental report and want your thoughts! This extra review could affect project timing and decisions about land use near Seminoe Reservoir.
Analyzed Economic Effects
5 provisions identified: 1 benefits, 0 costs, 4 mixed.
Adds 972 MW energy storage
The proposed Seminoe Project would add 972 megawatts (MW) of pumped storage capacity and is listed as capable of producing 2,916 gigawatt-hours (GWh) per year. The project is intended to provide energy storage and ancillary services to the electricity grid.
Local hunting/fishing/tourism review
The BLM will analyze the proposed right-of-way's reasonably foreseeable effects on the local economy, explicitly including the hunting, fishing, and tourism industries in central Wyoming. This analysis could inform decisions that affect businesses and workers in those industries.
Miracle Mile trout fishery review
The BLM will analyze how the proposed ROW could affect aquatic habitats and water quality of the North Platte River Blue Ribbon trout fishery within the Miracle Mile reach. That analysis is likely to matter to anglers, guiding services, and recreation-related businesses that rely on the fishery.
Recreation access impact analysis
The supplemental EIS will evaluate the proposed ROW's reasonably foreseeable effects on recreational accessibility of BLM-managed public lands near the project. The review could influence public access for hikers, hunters, anglers, and recreation businesses operating in the area.
Possible Rawlins RMP amendment
The BLM Wyoming State Director intends to prepare a Rawlins Resource Management Plan Amendment (RMPA) to evaluate the ROW application, including possible amendments addressing Visual Resource Management and Big Game Crucial Ranges. Changes to the RMP could alter land-use allocations and management direction in the planning area.
