IDANHA, Ore. (AP) — A stretch of Highway 22 will be closed for much of this week as crews clean up gasoline and diesel fuel that leaked out of a crashed tanker truck near Idanha along the North Santiam River, state transportation authorities said Monday.
The highway between Idanha and Santiam Junction is unlikely to reopen until Friday or Saturday as crews remove contaminated soil in a roadside ditch and rebuild a 600-foot (183-meter) section of roadway, the Oregon Department of Transportation said.
An oil sheen was visible on the North Santiam River downstream of the crash site, but officials said most of the tanker’s oil seeped into the ditch, where it was absorbed by the soil. It’s unclear how much entered the river, the Statesman Journal reported.
The city of Salem said Monday that its drinking water is safe and the oil from the spill has not reached its water treatment plant near Stayton, which is about 30 miles (48 kilometers) away from the crash. The oil will take several days to reach the plant, the city said, and teams will test the river water at multiple locations this week. Crews have set up absorbent berms to capture the oil on the water.
If any fuel is detected in the river, the city will close the water intake gates as it did in a similar situation three years ago.
The crash on Sunday closed Highway 22 near Detroit and Santiam Junction. The truck was carrying 10,600 gallons (40,125 liters) of fuel total — 6,500 gallons (24,600 liters) of gasoline in a tanker trailer and 4,100 gallons (15,520 liters) of diesel in the truck’s tanker.
About 7,800 gallons (29,500 liters) of fuel emptied into a roadside ditch and the rest was recovered, according to Oregon Department of Environmental Quality officials.
