Debate stirred over 1st major US tar sands mine

Beneath the lush, green hills of eastern Utah's Uinta Basin, where elk, bear and bison outnumber people, the soil is saturated with a sticky tar that may soon provide a new domestic source of petroleum for the United States. It would be a first-of-its kind project in the country that some fear could be a slippery slope toward widespread wilderness destruction.

With crude prices surging beyond $100 a barrel, and politicians preaching the need to reduce America's reliance on foreign supplies, companies are now looking for more local sources. One Canadian firm says it's found it in the tar sands of Utah's Book Cliffs.

Alberta-based Earth Energy Resources Inc. aims to start with a roughly 62-acre mine here to produce bitumen, a tar-like form of petroleum, from oil-soaked sands. For decades, other Utah operators have used oil sands as a poor-man's asphalt, and Canada has been wringing oil from the ground for years, but nobody has yet tried to produce petroleum from U.S. soil on such a scale.

And it could be just the beginning. The company has over 7,800 acres of Utah state land under lease, with plans to acquire more, and estimates its current holdings contain more than 250 million barrels of recoverable oil.

"This is not just a 62-acre project that will last seven years. We are looking at a 30,000-acre project that will destroy the environment in this area over many years," said John Weisheit, a Colorado River guide and founder of the Moab, Utah-based environmental group Living Rivers.
