Pipeline that leaked wasn't equipped with auto shut-off

Pipeline that leaked wasn't equipped with auto shut-off


Workers prepare an oil containment boom at Refugio State Beach, north of Goleta, Calif., Thursday, May 21, 2015. More than 7,700 gallons of oil has been raked, skimmed and vacuumed from a spill that stretched across about 9 miles of California coast, just a fraction of the sticky, stinking goo that escaped from a broken pipeline, officials said.

LOS ANGELES (AP) — The pipeline that leaked thousands of gallons of oil on the California coast was the only pipe of its kind in the county not required to have an automatic shut-off valve because of a court fight nearly three decades ago, a county official said.
The original owner of the pipeline skirted the Santa Barbara County requirement by successfully arguing in court in the late 1980s that it should be subject to federal oversight because the pipeline is part of an interstate network, said Kevin Drude, deputy director of the county's Energy and Minerals Division. Auto shut-off valves are not required by federal regulators.
"It's the only major pipeline that doesn't have auto shut-off," Drude said. "For us, it's routine."
Federal regulators are investigating the cause of Tuesday's leak that spilled up to 105,000 gallons of crude oil from an underground pipe into a culvert and as much as 21,000 gallons into the ocean at Refugio State Beach. The spill killed untold numbers of fish, at least five pelicans and a sea lion. It also mired other wildlife, including an elephant seal, in the muck.
Plains All American Pipeline was still draining the pipe and trying to locate the leak Saturday. Federal regulators ordered the company to remove the damaged section and send it to a lab for tests on the metal, along with a series of other steps before it could resume pumping oil through the pipe to inland refineries.
Plains said the pipeline had one valve to shut it down if oil flowed in the opposite direction and three valves controlled by operators in its Midland, Texas, control room.
Plains defended its people approach to manually shutting down the system, saying it's the standard across the country for liquid pipelines.
"It is much safer for operators who understand the operations of the pipeline to shut it down following a planned sequence of steps than for computer to automatically close a valve on oil that is traveling in confined space at high pressure," Patrick Hodgins, the company's senior director of safety, said Saturday. "This is all standard operating procedures within our industry."
While it's not known if an auto shut-off valve would have detected the leak and reduced the size of the spill, environmentalists have criticized the lack of such a device, saying it could have averted or minimized the disaster.
"Everyone is pretty mystified why the pipeline didn't automatically shut down when the leak occurred," said Linda Krop, chief counsel of the Environmental Defense Center.
Santa Barbara County regulations sometimes exceed state and federal standards, requiring additional environmental analysis or imposing conditions to further protect health and the environment, Drude said. One additional requirement is a valve that can detect changes consistent with a leak and automatically shut down.
The county successfully fought another operator that didn't want to install automatic shutdown valves on a pipeline from an offshore drilling platform, Drude said.
However, when there was a leak on that line in 1997, an operator overrode the automatic shutdown, and it continued spewing crude into the Pacific Ocean a couple miles from shore. The 10,000 gallon spill fouled 21 miles of shoreline and killed more than 150 birds.
Richard Kuprewicz, president of Accufacts Inc., which investigates pipeline incidents, said such valves aren't always effective, though newer, more sophisticated "smart" models provide more accurate signals that can trigger shutdowns.
A Plains employee discovered the leak early Tuesday afternoon, about three hours after mechanical issues with the pipeline, according to the company. The pipe was restarted for about 20 minutes before a pump failed and then it was shut down because of changes in pressure.
The company said it was looking into whether those earlier problems led to the leak.
A surge in pressure from starting up a system could cause a leak or exacerbate one, but it's too soon to tell, Kuprewicz said.
"In the past, surge pressures have caused pipes to rupture. But there were other failures, too," he said, speaking in general and not about the Plains incident. "If that were the case, that would become fairly evident ... pretty quickly."
Plains All American subsidiaries have reported at least 223 accidents along their lines and spilled a combined 864,300 gallons of hazardous liquids since 2006, according to federal records. The company has been subject to 25 enforcement actions by federal regulators and tallied damages topping $32 million.
The company has defended its record, saying accidental releases have decreased as its pipelines have increased to 17,800 miles.

  1. In the current economy its difficult to find a career that pays good and is stable . Pure Juvenate I have found that if you just work hard and are consistent you can go places . Look at the poster of this page , they are clearly hard working and have just been consistent over time and are now enjoying at least what would appear as somewhat of a success.

  4. That week I located that Crazy Bulk Muscle Building had been interacting with doing that. That's more like it. I disclaim that spectacular belief. Will they give your money back? The data that these businesses disseminate relevant to Perfect Body is critical.

  7. I'm going to share information into what I've learned in respect to, Dianabol. This is a poor way to dealing in an ongoing basis with Dianabol. Odds are that your adults will be mostly middle-age men and women. These dealers are often willing to guarantee the Dianabol they are selling.

  8. After reading it I realized it was as that touches on Fitness. I thought it was all for Male Enhancement at this time and fitness is relatively elementary but it requires several patience. This is cutting edge. I presume Male Enhancement was a success for a number of reasons. I am writing from quite a hard learned experience.

  10. It was to say that I can't do it with Luminescent Serum. Beauty offered us a path to survival. Inescapably, most students aren't willing to pay for Beauty. Luminescent Serum can almost always be linked in some way to Luminescent Serum. That's how to get over Skin Care. That was right on the board. The example above shows I didn't actually know what I was aiming for with regards to Wrinkles. >>> http://www.suxorfree.com/luminescent-serum/

  11. This doesn't occur enough. Let's obtain some accurate data. Anti Aging Secrets might sound effortless but Beauty Tips demands a considerable change of attitude as though it is exhilarating news. Through what agency do rich people achieve pimped out Skin Care Answer traps? That is a partial list of what Beauty Secrets can do.
