BLM Opens Public Comment Period for Proposed Carbon Storage Project in Southwest Wyoming

The Bureau of Land Management (BLM) is inviting public input on a proposed carbon dioxide (CO₂) storage project that could permanently sequester greenhouse gases deep underground in southwestern Wyoming.

The agency released an environmental assessment analyzing the potential impacts of granting a right-of-way to Pond Field, LLC, for the Sweetwater Carbon Storage Hub.

The proposed project would utilize approximately 44,350 acres of federal pore space across Uinta, Sweetwater, and Lincoln counties to store carbon dioxide. The BLM’s environmental review evaluates the long-term effects of CO₂ injection into deep geologic formations, a process known as carbon sequestration. This technique is increasingly used to reduce atmospheric carbon emissions and is seen by supporters as a step toward cleaner domestic energy production.

Pond Field, LLC has already received authorization from the Wyoming Department of Environmental Quality to construct three Class VI Underground Injection Control wells on adjacent non-federal lands. These wells, which are regulated by the state, will serve as the primary injection sites for the proposed storage activities.

Carbon sequestration has gained attention in recent years as part of broader efforts to balance energy development with environmental stewardship. The BLM notes that the project supports innovation, infrastructure investment, and job creation, aligning with the Trump administration’s emphasis on expanding American energy resources.

To ensure community voices are heard, the BLM has opened a 15-day public comment period, closing on April 30, 2025. Members of the public can review the environmental assessment, maps, and submit feedback through the BLM’s National NEPA Register using the “Participate Now” option. Written comments may also be mailed to:

BLM Kemmerer Field Office
Attn: Sweetwater Carbon Storage Hub
430 N. Highway 189
Kemmerer, WY 83101-9711

For additional information, the public is encouraged to contact Kelly Lamborn at 307-828-4505 or via email at [email protected].

The BLM will consider all submitted comments in its final decision regarding the project.
