BLM to review sage grouse assement of Western states

October 6, 2016

An 800-page assessment of mineral resources on 10 million acres in six Western states that will help federal officials decide whether to ban potential mining on the land to protect sage grouse was released on Oct. 4.

The review, requested by the U.S. Bureau of Land Management, looked at areas with high numbers of sage grouse and high-quality habitat for the bird.

The Associated Press reported that the BLM will use the study to help it evaluate the economic and environmental trade-offs of withdrawing the public lands from mining in Idaho, Montana, Nevada, Oregon, Utah and Wyoming for 20 years.

“The report is critical to give us an idea of what the potential is for development,” said BLM spokesman Mark Mackiewicz.

The agency plans to release a draft environmental impact statement in December outlining possible alternatives.

Sage grouse are found in 11 Western states. About 200,000 to 500,000 remain, down from a peak population of about 16 million.

The proposed withdrawal of the lands is part of new U.S. policies announced in late 2015. At the same time, the U.S. Fish and Wildlife Service said sage grouse didn't need federal protections under the Endangered Species Act, a decision that will be reviewed in about four years.

Under the 1872 mining law, federal officials don't have the discretion to deny mining claims, however, withdrawing the 10 million acres from being subject to that law would allow BLM officials to block mining claims.

The 10 million acres are already under a temporary freeze from new mining claims while the BLM prepares the environmental impact statement. The freeze doesn't affect mining claims already in place.

The U.S. Geological Survey in preparing the report examined the potential mineral development in remaining sage grouse strongholds. The study found that in Wyoming, key sage grouse habitat sits atop bentonite.

The Wyoming Mining Association says bentonite has many uses, including drilling fluids and sealants, and that Wyoming is the nation's leading producer of it and cutting off access would harm the state.

“If that’s the trajectory that this goes, we’re absolutely going to oppose such a measure," said Travis Deti, the group's acting executive director. "We would certainly hope they would not use this as a tool to place more burdens on the mining industry in our state.”
