RUTLAND, Vt. — Vermont officials say few convenience stores have stopped selling gasoline since a new state law was implemented that requires double-walled storage tanks.

The Rutland Herald reports about eight sites stopped selling gas, but some may reopen later this year with the required tanks. The state Department of Environmental Conservation says other sites stopped selling gas for reasons unrelated to the state law.

Double-walled storage tanks prevent groundwater from coming into contact with gasoline when the exterior or interior wall is damaged.

Ted Unkles, coordinator for the DEC’s underground storage tank program, says installing a proper tank can cost gas stations close to $200,000.

One gas station owner says he doesn’t plan on selling gasoline again because the profit margin isn’t enough to cover the cost of installing a new tank.
