Among other actions are:

• The issuance of a new BLM handbook on implementing the National Environmental Policy Act, or NEPA, which exempts some drilling, logging and mining activities from environmental review.

• A commitment by the BLM's Utah office to issue six resource-management plans this summer that will set the stage to offer almost 9 million acres for oil and gas leases.

• Revisions of the BLM's manual on threatened and endangered species that would remove state-designated species from protection on BLM land. Among the species losing protection in Colorado would be the kit fox and boreal toad.

• New National Forest Management Act regulations, filed April 21, that would remove protecting species on national forest land as a management goal and loosen controls on logging.

• A commitment by the BLM to issue proposed oil-shale- leasing rules this summer — even though Congress has prohibited the bureau's spending money on issuing final rules.

• An effort by the U.S. Fish and Wildlife Service to issue by December its final rule on whether to protect the greater sage grouse — even though in a court settlement the agency had agreed to issue it in 2009.

• The granting by the BLM of "categorical exemptions" created under the 2005 Energy Policy Act to spare drilling operations from environmental reviews in areas where drilling has already taken place.

In each of the cases, a succeeding presidential administration could reverse policies and rules — though it might take time.

"Virtually nothing is undoable," said Trent Orr, an attorney with Earthjustice, an advocacy law firm that has sued to block the Forest Service management rules.

"But the more that the Bush administration does, the longer it will take to undo," Orr said.
