About gas prices in Maryland
Maryland is a PADD 1B Central Atlantic state with reformulated gasoline requirements in the Baltimore-DC corridor that add 5 to 15 cents per gallon over the rest of the state. The state gas tax is around 47 cents per gallon, among the highest on the East Coast. Baltimore, Annapolis, and the DC suburbs (Bethesda, Silver Spring, Rockville) all draw supply from harbor terminals at Port of Baltimore plus pipeline imports through Plantation and Colonial systems. Costco, Sam's Club, BJ's Wholesale (popular in the suburbs), Wawa, and Royal Farms lead on value across Baltimore, Annapolis, and Rockville. Western Maryland (Hagerstown, Cumberland) typically tracks Pennsylvania pricing rather than the Baltimore-DC corridor.
