UPDATE: About 300 gallons of diesel fuel leak from train in Columbia River Gorge, official confirms

Update 9:25 a.m. Wednesday



Hundreds of gallons of diesel fuel likely leaked from a train that was traveling Tuesday in the Columbia River Gorge, a Union Pacific spokesman said.

It appears 200 to 400 gallons of fuel leaked from the train, said Justin Jacobs, a Union Pacific spokesman.

Authorities determined fuel didn't enter any waterways, Jacobs said in an email.

The 92-car train was stopped in the Bridal Veil area, Jacobs said. The leak apparently came from a locomotive, he said. Hazmat workers and other officials responded Tuesday night.

"Personnel will be on scene (Wednesday) morning to better assess the site during daylight hours and conduct soil remediation as necessary," Jacobs said.

Some of the fuel may have evaporated, he said.

A broken cap on a fuel filter looks to be the source of the leak, said Capt. Steve Alexander, a Multnomah County Sheriff's Office spokesman.

The train was headed east from Portland, Jacobs said. No one was injured.

The leak comes on the heels of an oil train derailment that spilled 42,000 gallons of oil, sent a billowing cloud of black smoke into the air and created a small oil sheen on the Columbia River near the town of Mosier earlier this month.

Almost 300 people were evacuated from their homes because of the derailment, which also damaged the town's sewage treatment plant.
