Drivers in the Binghamton area area shelling out more money every time they fill up a vehicle.

Regular gasoline has jumped back to the four-dollar-a-gallon mark at some Broome County stations.

Prices have gone up more than twenty cents a gallon so far this year in the Binghamton market.

According to the AAA's Daily Fuel Gauge Report, today's current average price in the Binghamton area is about $3.90 a gallon. The average local price has increased by eleven cents over the past week.

The AAA report indicates the current New York state average price is about $3.91 a gallon while the average Pennsylvania price is listed at $3.69 a gallon.

The least expensive gasoline in the United States is reported to be in Wyoming, with an average price of about $2.99.

The AAA survey shows the state with the highest average price right now is Hawaii, which is posting an average of nearly $4.19 a gallon.

The higher gasoline prices are occurring as some refineries are undergoing maintenance. Prices also might be affected by Hess Corporation's move to get out of the refining business.

Hess has announced plans to close its New Jersey refinery by the end of this month. The company says it intends to sell its U.S. terminal network.

Hess has closed some of its under-performing gas retail sites in recent years.
