ANCHORAGE - Alaska environmental regulators are monitoring plans to remove thousands of gallons of liquefied propane gas from a tank that slid down a steep slope after the semi-truck towing it rolled over on the Glenn Highway.
No one was hurt and none of the 9,000 gallons of propane spilled in the Monday morning mishap 24 miles east of Sutton.
Officials with the state Department of Environmental Conservation say the Crowley Marine Services tractor-trailer hit a guard rail as it headed east. The tank and trailer detached from the truck and slid about 440 feet down the slope.
Gary Folley with the DEC says the plan is to stabilize the tank, pump two-thirds of the propane to another tank and flare off the rest of the propane before retrieving the stranded tank.
