ANCHORAGE - The Corps of Engineers district office in Anchorage is reviewing whether a buried pipeline is a feasible alternative to a proposed bridge across the Colville River.
Conoco Phillips proposed the road bridge to move oil from its leased site in the National Petroleum Reserve-Alaska on the North Slope.
The corps said last year that would violate the Clean Water Act because a buried pipeline would be less harmful to the Arctic river.
Conoco Phillips appealed, and the agency's review officer this month told the district office to show that the pipeline was "logistically practicable."
The Anchorage Daily News reports the drill site would be a satellite of the oil company's Alpine oil field near Nuiqsut. If developed, it would be the first commercial oil production from NPR-A.
The corps district workers are going through the points raised in the appeal and reviewing their files.
"We will also likely need to engage in additional coordination with Conoco Phillips Alaska and the agencies," said spokeswoman Pat Richardson.
