New Oil Train Rules Are Hit From All Sides

Ending months of uncertainty and delays, federal regulators on Friday unveiled new rules for transporting crude oil by trains, saying the measures would improve rail safety and reduce the risks of a catastrophic event.

But the rules quickly came under criticism from many sides. Lawmakers and safety advocates said the regulations did not go far enough in protecting the public, while industry representatives said some provisions would be costly and yield few safety benefits.

More than two years in the making, the rules followed a spate of derailments, explosions and oil spills around the country that highlighted the hazards of shipping large quantities of potentially explosive material on rails. The regulations introduce a new tank car standard for oil and ethanol with better protections, and mandate the use of electronically controlled brakes.

Facing growing pressure from members of Congress as well as local and state officials, the Department of Transportation has taken repeated steps in the last two years to tackle the safety of oil trains and reassure the public. Last month, for example, it set lower speed limits for oil trains going through urban areas.

Under the new rules, the oldest, least safe tank cars would be replaced within three years with new cars that have thicker shells, higher safety shields and better fire protection. A later generation of tank cars, built since 2011 with more safety features, will have to be retrofitted or replaced by 2020.

Oil trains — with as many as 120 cars — have become common sights in cities like Philadelphia, Albany and Chicago as they make the slow journey from the Bakken region of North Dakota, where oil production has surged in recent years.

Local and state officials have complained that rail-friendly rules make it difficult to predict when trains will pass through.

But regulators retreated from a provision that would have forced railroads to notify communities of any oil train traffic. Instead, railroads will need to have only a “point of contact” for information related to the routing of hazardous materials.

Several members of Congress, particularly those representing states like Washington, Oregon, North Dakota and New York that have seen a surge in train traffic, said the rules did not go far enough and signaled that legislation might be needed.

Senators Ron Wyden and Jeff Merkley of Oregon said they were disappointed that transportation officials had not expanded public information about oil train routes.

“Instead of providing first responders more details about oil shipments, railroads will simply be required to give our firefighters a phone number,” they said.

Railroads said they welcomed the new regulations but objected to a provision that would require tank cars to have electronically controlled pneumatic brakes by 2021. The Department of Transportation said the new brakes, known as E.C.P., are more effective than air brakes or dynamic brakes that are currently being used.

“The D.O.T. couldn’t make a safety case for E.C.P. but forged ahead anyway,” Edward R. Hamberger, the president and chief executive of the Association of American Railroads, said in a statement. “I have a hard time believing the determination to impose E.C.P. brakes is anything but a rash rush to judgment.”

The railroad association has estimated in comments filed to the Transportation Department last year that installing the new brakes would cost $9,665 per tank car. The Railway Supply Institute, which represents tank car makers, also pushed against the use of those brakes, saying their effectiveness was not proved and would not provide a significant safety advantage.

Transportation officials said the new type of brakes was already in use by some railroads for other types of commodities. Their use would decrease the chances of a catastrophic pileup, reduce the number of punctured cars in an accident, or allow train operators to stop faster if there was an obstacle on the tracks.

Sarah Feinberg, the acting administrator of the Federal Railroad Administration, said: “The mission of the F.R.A. is safety and not focusing on what is convenient or inexpensive or provides the most cost savings for the rail industry. When I focus on safety, I land on E.C.P. It’s a very black-and-white issue for me.”

There have been five explosions and spills this year alone, four in the United States and one in Canada. In July 2013, 47 people died in Canada after a runaway train derailed and exploded in the city of Lac-Mégantic, Quebec.

“I am hopeful the rail industry will accept this rule, and will follow this rule,” Anthony Foxx, the transportation secretary, said at a news conference in Washington. He appeared with Canada’s transport minister, Lisa Raitt, who said Canadian and American regulations would be aligned.

A central question before the administration was to determine what level of protection the new generation of cars should have and how quickly to roll them out.

The new rules create a new standard, “high-hazard flammable trains,” defined as “a continuous block of 20 or more tank cars loaded with flammable liquid or 35 or more tank cars loaded with a flammable liquid dispersed through a train.”

By 2018, the rule would phase out older tank cars, DOT-111s, long known to be ill suited for transporting flammable material. A newer generation of cars, known as CPC-1232, would have to be retired or refitted to meet the new standard, DOT-117, by 2020.

All cars built under the DOT-117 standard after Oct. 1, 2015, will have a thicker nine-sixteenths-inch tank shell, a one-half-inch shield running the full height of the front and back of a tank car, thermal protection and improved pressure-relief valves and bottom outlet valves.

Senator Charles E. Schumer, Democrat of New York, said Friday’s announcement gave railroads too much time to remove older cars from service. Mr. Schumer was one of seven senators who unveiled a bill that would seek to impose a fee of $175 per shipment on older cars to speed up their removal from service.

“The good news is that the standards are predictable, but the bad news is that the phaseout time is too lenient,” Mr. Schumer said.

Senator Marie Cantwell, Democrat of Washington, was more forceful, saying that the new regulations also failed to reduce the volatility of Bakken crude, which is more likely to catch fire and explode than other forms of crude.

“It does nothing to address explosive volatility, very little to reduce the threat of rail car punctures, and is too slow on the removal of the most dangerous cars,” she said. “It’s more of a status quo rule.”

Oil companies, though, said the mandate to build new tank cars to replace older models starting in 2018 would stretch the industry’s manufacturing ability and lead to shortages.

Placing blame on the railroads, Jack Gerard, the chief executive of the American Petroleum Institute, said regulators should focus instead on preventing derailments and enhancing track inspection and maintenance.

The spectacular growth of oil production from the Bakken region, negligible only a few years ago and now exceeding a million barrels a day, has transformed the domestic energy industry. It has placed the United States back on a path to oil self-sufficiency, and profoundly disrupted international energy markets.

U.S. Sets New Rules for Oil Shipments by Rail

Ending months of delays and uncertainty, federal regulators on Friday disclosed new rules for safer transportation of crude oil by trains, introducing a new tank car standard and mandating the use of new braking technology.

The regulations, more than two years in the making, followed a spate of derailments, oil spills and fiery explosions involving oil trains around the country that have highlighted the risks involved in shipping large quantities of explosive material on rails through cities.

The rules state that the oldest, least safe tank cars should be replaced within three years with new cars that have thicker shells, higher safety shields and better fire protection. A later generation of tank cars, built since 2011 with more safety features, will have to be retrofitted or replaced by 2020.

It is the second time in weeks that the Department of Transportation has announced new rules for rail shipments to instill public confidence. Last month, it set lower speed limits for oil trains going through urban areas.

There have been five explosions and spills this year alone, four in the United States and one in Canada. In July 2013, 47 people died in Canada after a runway train derailed and exploded in the city of Lac-Mégantic, Quebec.

“I am hopeful the rail industry will accept this rule, and will follow this rule,” Transportation Secretary Anthony Foxx said at a news conference in Washington. He appeared with Canada’s transport minister, Lisa Raitt, who said Canadian and American regulation would be aligned.

There has been growing pressure from local governments, members of Congress, safety experts and environmental advocates for federal action. The question before the administration was to determine what level of protection the new generation of cars should have and how quickly to roll them out.

The new rules create a new standard, “high-hazard flammable trains,” defined as “a continuous block of 20 or more tank cars loaded with flammable liquid or 35 or more tank cars loaded with a flammable liquid dispersed through a train.”

By 2018, the rule would phase out older tank cars, DOT-111s, long known to be ill suited for transporting flammable material. A newer generation of cars, known as CPC-1232, would have to be retired or refitted to meet the new standard, DOT-117, by 2020.

Regulators retreated from a provision that would have forced railroads to notify communities of any oil train traffic. Instead, railroads will be required to have a “point of contact” for information related to the routing of hazardous materials.

Some critics asserted after Friday’s announcement that the regulations would do little to prevent another spill or explosion while older cars remained in operation.

On Thursday, seven senators, including Charles E. Schumer, Democrat of New York, unveiled a bill that would seek to impose a $175 per shipment fee on older cars to speed up their removal from service.

Senator Schumer said Friday’s announcement gave railroads too much time to remove older cars from service.

“The good news is that the standards are predictable, but the bad news is that the phaseout time is too lenient,” he said. “Our railroads are changing, and are getting much busier because of all this oil business, and they will have to adapt. They can’t do it the old way.”

The Association of American Railroads said it backed the new tank car requirements but objected to a requirement that railroads should adopt new electronically controlled pneumatic brakes, or E.C.P., starting in 2021 for oil trains.

“The D.O.T. couldn’t make a safety case for E.C.P. but forged ahead anyway,” Edward R. Hamberger, the president and chief executive of the Association of American Railroads, said in a statement. “I have a hard time believing the determination to impose E.C.P. brakes is anything but a rash rush to judgment.”

Why bitumen isn’t necessarily safer than Bakken

The chain reaction fireballs that attended the Feb. 16, 2015 derailment of a CSX unit oil train in populated West Virginia probably blinded observers to the significance of the concurrent derailment and explosions of a CN oil train in a remote and uninhabited area of northern Ontario. Most reports treated the two events as equals, given that both trains consisted of recently manufactured CPC-1232 tank cars loaded with crude oil.

CN’s Ontario conflagration is the more disturbing of the two mishaps: The railroad reported that its train was not carrying the extra-light Bakken crude that, in a series of high-energy derailments since 2013, has proved to be explosive. To the contrary, the CN train was laden with bitumen, the extra-heavy tarry substance extracted from Alberta’s oil sands. Bitumen, in its natural highly viscous form, is considered to be essentially inflammable by petrochemical experts and is rarely considered in safety evaluations of crude by rail.

So why did the bitumen ignite and explode in Ontario’s -40ºC (-40ºF) weather? The reason, based on research consulted by Railway Age, is that the diluent added to make bitumen flow into and out of tank cars makes the blended lading quite volatile.

This blend of bitumen and petroleum-based diluents, known as “dilbit,” has a low flash point. Thus, the widespread belief that bitumen from Alberta’s northern oil sands is far safer to transport by rail than Bakken crude is, for all intents and purposes, dead wrong. This may be disruptive news for bitumen shippers, carriers, and regulators.

The hope for Bakken crude is that it can be treated to remove benzene and other “light end” substances before loading, rendering it mildly flammable instead of highly explosive. The same is not true for dilbit, because the highly volatile diluents are added to the crude to make it less viscous. A safer procedure is to heat bitumen at origin before loading into a tank car and again at destination, prior to unloading. Some tank cars are equipped with internal steam coils for this purpose and are used in crude oil service, but a requirement for such heating elements is not included in the specifications proposed for a future DOT-117 tank car to replace both the DOT-111 and CPC-1232 cars now in CBR service.

According to “Properties of Dilbit and Conventional Crude Oils,” a February 2014 report by the Alberta Innovates consortium of industry, government, and university researchers, “[T]he flash point of fresh dilbit is initially lower than other oil types and is comparable to a diluent.” It says that dilbit will ignite upon exposure to an ignition source at -35ºC, compared to -9ºC for conventional light oil. The flash point of raw diluent is -35ºC or less. The flash point of undiluted bitumen is +151ºC, well above the +60ºC flammability threshold specified in current hazardous materials classification regulations.

The reason for the low flash point of dilbit is that ignitability is determined by a blend’s most volatile components, in this case, the diluent itself: “[T]he flash point is determined by the lowest-boil-point components (volatiles). Consequently, the flash point of the dilbit is governed by the 20%-30% volume diluent component . . . .”

The study defines flash point as “the temperature to which the fuel must be heated in order to produce an adequate fuel/air concentration to be ignited when exposed to an open flame. The flash point of the crude oil is used as an index of fire hazard in North America.”

Thus, flash point is the critical factor in determining whether a tank car breach will lead to its contents burning or exploding upon exposure to the pyrotechnics of a high-energy derailment.

Canada’s Transportation Safety Board can be expected to analyze the dilbit lading of CN’s Ontario accident, as it did the Bakken crude that exploded at Lac-Mégantic in 2013. TSB reported then that Bakken crude is more volatile than other varieties. Should TSB conclude that dilbit has a volatility similar to Bakken crude, as the Alberta research suggests, the hazmat classification of crude oil could be in question.
