The 50-plus tank cars that have been sitting along N. Mt. Shasta Blvd. for the past three weeks should be gone soon, according to Valero, who owns the fuel.

The city was at first unsure whether the tanks were full of liquified petroleum gas, as they are clearly marked, or empty. However, Mount Shasta City Fire Department Chief said he now knows they're full.

Valero spokesperson Bill Day said Union Pacific will begin moving the tank cars beginning today or tomorrow, March 6. They are headed to one of Valero's refineries elsewhere in California, Day said.

Day said the cars' presence in Mount Shasta was a "temporary situation" and there is no intention of using those tracks as a permanent storage area.

"It is a one-time thing," Day said.

Union Pacific spokesperson Aaron Hunt said the tanks have been sitting on tracks owned by the McCloud Railroad. Questions were referred to Court Hammond, who is listed as the CEO of the Yreka Western Railroad. Phone calls and emails to Hammond have gone unreturned.

Though some in the community have been concerned about the safety of so many filled tanks of fuel sitting in Mount Shasta, Melo said they are very safe.

Each tank can hold more than 30,000 gallons of liquified petroleum gas, Melo said. All the tanks are double walled, with an eight-inch foam buffer between the outside and the inner tank. They are also equipped with safety valves.

The tanks are designed to be safe in transit and to take significant impact, Melo said. While accidents can happen, these tanks are as safe as possible.
