AUGUSTA — It’s costing Maine residents less to fill their gas tanks.

Price-monitoring website MaineGasPrices.com reports Monday that the average retail cost of a gallon of gas in the state has fallen 2 cents to $3.68.

That’s still 11 cents per gallon above the national average.

Prices in Maine are now more than 15 cents lower than at the same time last year and almost a dime lower than a month ago.

A company analyst says he optimistic that prices will continue to decline as the summer driving season winds down.

Maine prices are based on a survey of more than 1,200 gas stations in the state.
