President Obama is expected to allow drilling in the Atlantic Ocean for the first time in three decades in a draft plan that could be released as early as next week.

The five-year plan would run from 2017 through 2022 and would begin after Obama leaves office.

The Alaskan Arctic also will be in play, but the Interior Department's Bureau of Ocean Energy Management is reportedly seeking a change in how it offers leases to prospective drillers that industry officials say could deter interest.
