JUNEAU, Alaska — Alaska is proposing a plan aimed at determining the true oil and gas potential in the Arctic National Wildlife Refuge.

The plan was announced Monday by Gov. Sean Parnell and Natural Resources Commissioner Dan Sullivan.

Parnell says the U.S. Department of Interior hasn't indicated that it will address oil and gas issues in a new planning document for the refuge so Alaska is stepping up.

Alaska is proposing a multiyear plan that includes seismic surveys, environmental studies and exploration drilling on the coastal plain of the refuge. Exploration would take place in winter, and Parnell says it would have a limited impact on the environment.

Parnell says he will ask the Legislature for up to $50 million toward the plan, if the federal government is willing to partner with Alaska.
