CHEYENNE, Wyo. (AP) — State officials say they have requested details of alleged environmental problems that a company proposing to experiment with underground coal gasification in Wyoming caused with a similar project in Australia.

Officials in Queensland state, Australia, recently accused Linc Energy of causing “serious environmental harm” at an underground coal gasification plant near the town of Chinchilla. The allegations followed a nine-month investigation, according to an April 11 release from the Queensland government.
