State authorities say all contaminated soil from a spill of 1,900 gallons of aviation fuel has been removed.
The Fairbanks Daily News-Miner reports that the soil was contaminated when a Big State Logistics tanker-trailer rolled April 21. The accident happened about 20 miles north of Healy on the Parks Highway.
The truck driver was cited for negligent driving.
Officials say about 300 cubic yards of material was removed and delivered to a facility for incineration.
A release from the Alaska Department of Environmental Conservation says about 250 gallons of fluids were recovered with absorbent pads right after the spill. Another 900 gallons were pumped from a nearby ditch.
There were no reports of wildlife being affected by the spill.
