SALT LAKE CITY — Interior Secretary Ken Salazar called Tuesday for an investigation into last-minute changes made by the administration of President George Bush to favor oil companies in oil-shale leasing.
Salazar said the Bush administration locked in a bargain royalty rate on 30,000 acres of land for oil companies without any opportunity for review or comment.
"There are questions about whether the lease addendums are legal or should be rescinded," he said in a teleconference call with reporters.
Salazar said before he reverses any of the Bush administration changes, he wants his department's inspector general, Mary Kendall, to determine how the regulations were changed.
The Department of Justice already has launched a probe into whether Bush's Interior Secretary Gale A. Norton used her position to steer three of the six potentially lucrative oil leases to Royal Dutch Shell PLC, the company she works for now.
Salazar said Kendall's probe would be a separate matter.
In addition, Salazar said Tuesday he was opening a second, more environmentally sensitive round of oil-shale leasing for Colorado, Utah and Wyoming.
The Interior Department is offering smaller research-and-development leases with requirements for environmental safeguards and milestones for progress.
With the announcements, Salazar is taking a more cautious approach to oil-shale development, which could require enormous amounts of water and electric power in states with little of either.
Moreover, oil companies will have to meet a series of development benchmarks for their leases "so they just aren't held out there forever," Salazar said.
A trade group was unhappy that Salazar was reducing the size of development leases to a square-mile from eight times that size.
"Slashing the size of the potential commercial lease diminishes the incentives for investment and ignores the enormous upfront costs and risks undertaken to develop these technologically complex resources," The American Petroleum Institute said in a statement.
Glenn Vawter, executive director of the Colorado-based National Oil Shale Association, complained the 5 percent production royalty fixed by the Bush administration was too high, given the risks and uncertainty of trying to squeeze oil from fine-grained rock using extreme temperatures.
"Nobody – on the industry side or the opposition – was happy with the royalty rate," Vawter said.
Salazar has said the 5 percent rate sells taxpayers short because rates for conventional oil and gas production on public land range up to 18.8 percent.
Government and industry officials estimate as many as 800 billion barrels of oil – enough to displace oil imports for 100 years – is locked in sedimentary rock in parts of Colorado, Utah and Wyoming.
No company has conclusively shown an economical way of extracting the waxy petroleum, called kerogen, on a large scale.
Shell Exploration & Production Co., a major player with three research and development leases in Colorado picked up years ago, had no immediate reaction to Salazar's announcement.
Colorado Gov. Bill Ritter applauded the federal government's new restraint.
"The potential for oil shale development in Colorado, and the economic opportunity that it represents, is huge," Ritter said. "But the prospect of commercial-scale activities raises significant questions" about the effect on the environment and water supplies.
The Natural Resources Defense Council, The Wilderness Society and Western Resource Advocates praised Salazar for making the next set of leases more accountable.
"The history of oil shale has been plagued with scandal and cronyism, and today's announcement shows why we need a better approach to America's energy," said Bobby McEnaney, lands advocate for the Natural Resources Defense Council.
The last attempt to mine Colorado's oil shale, considered the region's richest, went bust when oil prices dropped and government subsidies dried up.
People still refer to "Black Sunday," May 2, 1982, when Exxon shut down a $5 billion project near the West Slope town of Parachute, putting 2,200 people out of work.
