Up to 1,200 gallons of home heating oil is estimated to have spilled at Norton Sound Regional Hospital in Nome.
According to a situation report from the state Department of Environmental Conservation, Norton Sound Health Corporation hired Bering Straits Native Corporation to conduct indoor air monitoring in the hospital. As of Monday, the monitoring showed no evidence of diesel vapors inside the hospital. About 200 cubic yards of contaminated soil also had been removed.
The department says the spill was discovered early Friday morning. Norton Sound Health Corporation estimates 800-1,200 gallons of diesel had leaked from an above-ground storage tank.
The department says it will continue to monitor cleanup activities.
