Northeast Gasoline Supply Reserve Act This bill requires the Department of Energy (DOE) to establish, maintain, and operate a Northeast Gasoline Supply Reserve of no more than 1 million barrels as part of the Strategic Petroleum Reserve. (The Northeast means the states of New Jersey, New York, Vermont, Pennsylvania, Connecticut, Rhode Island, Massachusetts, Maine, New Hampshire, and any other contiguous state that DOE determines appropriate.) The bill authorizes DOE to sell refined petroleum products from the reserve if the President finds that there exists, or is likely to exist within the next 30 days, a severe energy supply interruption.
