NEW YORK — Gasoline prices fell Wednesday as travel in the storm-battered Northeast remained restricted. The national average for a gallon of gasoline fell 1.3 cents overnight to $3.521 per gallon, according to AAA. That’s about 26 cents less than a month ago.

The drop in demand for gas has overshadowed limited production at the nine refineries in the region. Seven refineries have been operating at reduced rates and the other two closed. Crews worked to restore the facilities to normal operation but, in some cases, were hampered by power outages.
