Crude oil train shipments dwindle in California, for now

A year ago, California officials nervously braced for an influx of milelong trains carrying volatile crude oil to refineries in the Valley and on the coast – trains similar to the one that exploded two years ago in Canada, killing 47 people.

The trains never arrived. Although tank cars full of oil now roll daily through cities in the Midwest and East, provoking fears of crashes and fires, the number of oil trains entering California has remained surprisingly low, state safety regulators say, no more than a handful a month. In recent weeks, they appear to have dwindled to almost nothing.

The reasons appear to be mainly economic.

“Crude oil shipments from out of state have virtually stopped,” said Paul King, rail safety chief at the California Public Utilities Commission. “Our information is that no crude oil trains are expected for the rest of this month.”

Most notably, the BNSF Railway recently stopped running a 100-car train of volatile oil from the Bakken region of North Dakota through the Feather River Canyon and midtown Sacramento to the Bay Area. The trains, several a month, carried an estimated 3 million gallons of fuel each.

Bakken oil, a lighter type of crude, similar to gasoline, has gained a fearsome reputation since it entered the national scene a few years ago. A string of Bakken train explosions around the country prompted the federal government to issue a warning last year about the oil’s unusual volatility and launch efforts to write stiffer regulations on rail transport, including a proposal to require sturdier tank cars for oil.

Two more Bakken train derailments and explosive fires recently in West Virginia and Illinois triggered a new round of complaints that the federal government is dragging its heels in finalizing those regulations.

The BNSF train through Sacramento was believed to be the only train in California carrying 100 cars of Bakken oil. PUC rail safety deputy director King said his commission’s rail monitors have been told by owners of a Richmond oil transfer station in the Bay Area that refiners stopped the shipments in November as global oil prices dropped.

California Energy Commission fuels specialist Gordon Schremp said lower prices for other types of oil have made Bakken marginally less marketable in California, although that could easily change in the future.

Other projects, like a Valero Refining Co. plan to run two 50-car oil trains daily through Sacramento beginning this spring to its Benicia plant, have not yet gotten off the ground, in part because of political opposition. Under pressure from state officials, including Attorney General Kamala Harris, Benicia recently announced it is redoing part of its environmental and risk analysis of the Valero rail project. Valero has said it intends to ship lighter fuels, but has declined to say whether those will be Bakken.

State safety officials said the slowdown provides a bit more time to provide hazardous-materials training for more firefighters, as well as to put together a state rail-bridge inspection program and to upgrade disaster and waterway spill preparedness. But state officials said they still feel like they’re playing catch-up as they prepare for existing and future potential rail hazards.

“This apparent reprieve may seem helpful, but we still have substantial amounts of … hazardous materials traveling across California’s rail lines,” said Kelly Huston, deputy director of the state Office of Emergency Services. “It only takes one train to create a major disaster.”

Oil prices have begun rising again, and state officials say they expect Bakken shipments to Richmond and potentially elsewhere to be back on track at some point. “We don’t have any concrete info about when it will resume,” the PUC’s King said. “When prices come up, it is likely to resume, and that could be in months.”

Federal emergency rules require railroads to report to states when they run trains carrying more than 1 million gallons of Bakken crude, and then again when that amount changes by 25 percent or more. BNSF sent the state Office of Emergency Services a brief notice on Wednesday acknowledging it had not shipped more than 1 million gallons of Bakken on any train in the last week. The notice does not say how long ago the shipments stopped or when they may resume.

BNSF officials have contended in letters to the state that shipping information is proprietary and should be kept secret. A BNSF spokeswoman declined this week to discuss shipments with The Sacramento Bee, writing in an email, “Information regarding hazardous material shipments is only provided to emergency responders.”

King of the PUC said his monitors estimate that eight or more non-Bakken crude oil trains had been entering the state monthly from Canadian and Colorado oil fields recently, headed to refineries or transfer stations. The Canadian oil, called tar sands, is not considered as explosive as Bakken, but two tar-sands trains derailed and exploded in recent weeks in Ontario, creating fires that lasted several days.

The national concern about crude oil rail shipments follows a boom in domestic oil production, notably in North Dakota, where hydraulic-fracturing advances have freed up immense deposits of shale oil. Lacking pipeline access, North Dakota companies have turned to trains to ship the oil mainly to East and Gulf Coast refineries and to Washington state. Crude by rail shipments in the United States skyrocketed from 9,500 carloads in 2008 to 436,000 in 2013, according to congressional data.

California continues to produce a sizable amount of its own oil in Kern County and receives marine shipments from Alaska and foreign sources. Still, a recent state energy-needs analysis estimates the state could receive as much as 23 percent of its oil via train or barge from continental sources, including North Dakota, Canada, Texas and other Western states, in the coming years. That estimate is based on plans by refineries in Benicia, San Luis Obispo and Kern County to build rail facilities that can accommodate large crude transports.
