To prohibit the implementation of the Approved Resource Management Plan Amendment for the Buffalo, Wyoming Field Office of the Bureau of Land Management.

In 2015, the BLM published a management plan for the field office that allowed leases of certain public lands or mineral estates within the office's planning area for the development of coal.

In 2018, the U.S. District Court for the District of Montana in Western Organization of Resource Councils v. Bureau of Land Management ordered the BLM to complete a new environmental impact statement (EIS) for the management plan under the National Environmental Policy Act of 1969, which requires an agency to include all reasonable alternatives to its action and the environmental impacts resulting from the action. Specifically, the court ordered the BLM to issue an EIS that considers an alternative of not leasing coal under the management plan as well as an alternative that limits the amount of coal potentially available for leasing.

In response to the court order, the BLM published an amendment to the plan on November 27, 2024. The amended plan made no acres within the office's planning area available for future coal leasing in order to reduce greenhouse gas emissions. However, it allowed existing coal leases to be developed.
