The Trump administration is advancing a proposal that would replace President Barack Obama's principal attempt to cut U.S. greenhouse gas emissions with a new rule expected to go easier on the ailing coal industry.
The proposed lease area is on the opposite side of the Sangre de Cristo crest from Great Sand Dunes National Park and Preserve, which has sparked controversy.
The leases were planned for oil and gas activity in this south-central part of Colorado. The sale was scheduled to take place on September 6.
While the big, ground-dwelling bird known as the greater sage-grouse relies upon the West’s sagebrush steppe for its living, its survival may rest on a delicately negotiated set of agreements -- agreements that the Trump administration is set to upend.
