A carbon storage project in southeastern Wyoming would not have a “significant impact” on the environment, the Bureau of Land Management said Wednesday.

The decision clears the path for Tallgrass Energy to use 480 acres of underground federal “pore space” for permanent CO2 sequestration. BLM, an Interior Department agency, issued both the finding of no significant impact and a decision record authorizing the “right-of-way” for Tallgrass Energy’s Southeast Wyoming CO2 Sequestration Project.

The project “will not result in a significant impact on the human, natural and physical environment,” Timothy Novotny, field manager for BLM’s Rawlins Field Office, wrote in the finding.

The decision comes roughly a month after BLM issued a similar finding of no significant impact for another Tallgrass Energy project in Wyoming’s southwest corner. The Southwest Wyoming CO2 Sequestration Project is being developed by Moxa Carbon Storage, a wholly owned subsidiary of Tallgrass Energy.
