JUNEAU, Alaska (AP) — ConocoPhillips Alaska can proceed with an oil and gas exploration program in a portion of a vast petroleum reserve in the state after a federal judge denied a request from project opponents to halt it. But Gleason said the Bureau of Land Management is not required “to prevent all impacts to surface resources” in the reserve. The lawsuit names as defendants the Department of Interior and Bureau of Land Management and top agency officials, including Interior Secretary Doug Burgum. ConocoPhillips Alaska filed as an intervenor, in support of the government’s actions. Ian Dooley, an attorney with Earthjustice representing the plaintiffs, in a statement said Gleason’s decision does not end his clients’ challenge to the exploration program.
