September 3, 2023 - The Bureau of Land Management on Thursday opened a 30-day public comment period for the proposed Tallgrass Southeast CO2 Sequestration Project in Wyoming. If approved, Tallgrass could store carbon dioxide (CO2) in approximately 480 acres of sub-surface federal pore space in Laramie County. The comment period will close Sept. 30.

This proposal to permanently store carbon in underground rock formations will reduce atmospheric carbon, a BLM news release said. The proposal follows the June 2022 BLM policy update authorizing rights-of-way on public lands for the geologic sequestration of carbon dioxide.

In addition to the application submitted to the BLM, Tallgrass is working with the Wyoming Department of Environmental Quality on the required Class VI Underground Injection Control well permits. The permits would allow Tallgrass to construct and operate carbon dioxide injection wells. No BLM administered surface would be disturbed for this project.

Additional information, a map of the project area and instructions on how to comment are available online at the BLM National NEPA Register, eplanning.blm.gov/eplanning-ui/home.

Comments may also be mailed to BLM Rawlins Field Office, Attn: Andrew Kauppila, 1300 3rd St, Rawlins, WY 82301. For more information, contact Kauppila at 307-328-4227.
