Obama will invoke a provision in a 1953 law that gives him wide latitude to withdraw U.S. waters from future oil and gas leasing, said the people who spoke on condition of anonymity because the decision had not been announced. Until now the law has been used sparingly to permanently preserve coral reefs, walrus feeding grounds and marine sanctuaries, according to Bloomberg.

Obama's withdrawals would block the sale of new oil and gas leases in portions of the U.S. Atlantic and most of the Chukchi and Beaufort seas north of Alaska. They are not expected to affect drilling or production under existing leases, including 42 parcels that Royal Dutch Shell Plc, Hilcorp Energy Co., Eni Spa, Repsol Sa and other companies own in the Beaufort, according to a government registry last updated in June.
