Gas prices typically spike during the spring time, and North Dakota is about two-weeks away from seeing a 10 to 20 cent increase in gas prices.
Starting in February, refineries made the switch from their winter blend of gasoline to summer blends. The Environmental Protection Agency's Clean Air Act, sets higher standards for summer fuels, which requires more refining.
"When it comes to pricing gasoline it is multi faceted. There is supply and demand, then there's the EPA, and then there's the value of the U.S. dollar in your pocket," says Eugene Graner of Heartland Investor Services.
Graner says that the spike is temporary, and drivers will typically see a decrease in prices next September, as companies switch back to winter blends.
