BLM Seeks Public Feedback on Proposed Carbon Sequestration Project in Southeast Wyoming

The Bureau of Land Management (BLM) has opened a 15-day public comment period on a draft environmental assessment related to the Southeast Wyoming Carbon Dioxide Sequestration Project.

The assessment focuses on the right-of-way application submitted by Tallgrass Energy, which seeks authorization to use 480 acres of subsurface federal pore space for long-term carbon dioxide storage east of Cheyenne.

If approved, the project would involve the permanent geologic sequestration of CO2, a process designed to mitigate carbon emissions by injecting and storing carbon dioxide underground. Tallgrass Energy is also applying for Class VI underground injection control well permits, which fall under the jurisdiction of the Wyoming Department of Environmental Quality. Notably, the current application does not propose surface development for related infrastructure.

Public input is being sought on the designated parcels, potential deferrals, and the overall environmental impact of the project. The BLM will incorporate public feedback into its review process to ensure compliance with all relevant laws, regulations, and land use policies.

Additional details and opportunities for public comment are available on the BLM National NEPA Register under the “Participate Now” option. The comment period will remain open until April 3, 2025. For further inquiries, individuals can contact the BLM Rawlins Field Office at 307-328-4224.
