Pipeline Problems: The Mess Stays One Year After Kalamazoo River Oil Spill

Right now final yr, I used to be a very unhappy man. A whole lot of hundreds of gallons of oil were dashing down the Kalamazoo River in direction of the good Lakes from southwest Michigan after a pipeline burst within the wee hours of the night. My employees was concerned as a result of it appeared to us as though the petroleum in the river was of a very nasty variety — tar sands — but no person seemed to byproduct of oil refining crossword puzzle understand or care regardless of the likelihood of a good uglier mess. Looking again a year later, the cleanup continues on the banks of the Kalamazoo River and it is obvious that we were asking the appropriate questions. The oil spill packed an even bigger wallop than anyone byproduct of oil refining crossword puzzle expected on the time due to the distinctive properties of tar sands oil. Within the final twelve months we have discovered quite a bit about the particular kind of tar sands oil that spurted into Michigan’s waters. I must say, I am not comforted by what we now have found or the lessons that appear unlearned from the spill.

Final July, we made inquiries with quite a few authorities trying to get information on what had spilled after noticing that the pipeline doubtless serviced BP’s Whiting Refinery in Indiana, one in all the biggest refiners of Alberta’s heavy tar sands oil. Figuring out that tar sands oil is considered by many to be the dirtiest on the planet due to its increased levels of heavy metals, assorted contaminants and better carbon liabilities, we were involved. In the havoc of the spill, we found technical data exhausting to come by and little understanding of why we have been asking the question — so we labored with OnEarth journal to ship a reporter to the spill site to get some answers. She was stonewalled. Informed again and again that tar sands oil was not concerned… Until she discovered the source of the oil and helped force the CEO of Enbridge Vitality, owners of the pipeline, to admit that the gunk that had spilled was indeed tar sands oil, despite repeated assertions to the opposite.

Why does it matter After all, once we established it was tar sands oil, the EPA stated that the kind of oil wouldn’t impact how they moved forward with the cleanup. You see, tar sands will not be your typical oil. It is a thick, heavy, dense petroleum steamed or strip mined out of Alberta’s sandy soil that is the consistency of peanut butter at room temperature. Truthfully, at the time, we didn’t even actually respect how unhealthy the information could be. It has since develop into clear that raw tar sands oil — diluted bitumen (or “DilBit’) — spilled in Michigan. These things is fundamentally completely different from different types of oil transferring via American pipelines. It is so thick and sludgy that it requires a mixture of condensed natural gasoline to thin it together with added heat and stress just to move it by way of a pipeline. At the time of the spill, it appears no one was conscious that this form of petroleum was in the combo. And lack of transparency is a problem, given a few of DilBit’s unique properties. First responders weren’t warned that outside of the pressurized atmosphere of the pipeline, the liquefied gases separate (creating a probably explosive and deadly cloud rife with benzene and noxious gases) and the heavy bitumen sinks to the bottom of the river. The state of Michigan released a report exhibiting that a whole lot of individuals along the river have suffered through an array of respiratory illnesses because of their exposure to the spilled DilBit. And, after all, cleanup crews have been centered on skimming the surface, not the much larger mess gumming up the river backside.

OnEarth despatched the identical reporter again lately to verify up on the cleanup. This is how she described the accident:

When that combination, often called DilBit, spilled out of the ruptured pipeline, the benzene and other chemicals in the mixture went airborne, forcing necessary evacuations of surrounding homes (lots of which were later purchased by Enbridge as a result of their house owners could not safely return), whereas the thick, heavy bitumen sank into the water column and coated the river and lake bottom, mixing with sediment and suffocating bottom-dwelling plants, animals, and micro-organisms.

Surface skimmers and vacuums had been no help, and a full yr later, EPA officials and scientists are nonetheless working on a plan to remove submerged oil from about 200 acres of river and lake bottom. EPA officials had given Enbridge an August 31 deadline to get all the oil out, however they now say a full cleanup could take years. “Where we thought we is likely to be winding down our piece of the response, we’re truly ramping again up,” said Mark Durno, considered one of EPA’s on-scene coordinators. “The submerged oil is a real story — it is a real eye-opener… In bigger spills we have dealt with before, we have not seen practically this footprint of submerged oil, if we’ve seen any in any respect.”

Look, this isn’t just me — watch the wonderful video beneath put together by the Kalamazoo Gazette this week. In particular, take a look at the EPA staffer’s almost identical description of the spill and his ideas about how this spill cleanup was completely counter to EPA’s expectations going in. He notes that: “I don’t think anybody anticipated that we’d spend… extra time dealing with the submerged fairly than surface oil…”

Nicely, we did.
And Enbridge should have… if they have been willing to fess as much as what was coursing by their aging strains.

But historical past repeats itself. Last month ExxonMobil said that tar sands oil was not involved in the Yellowstone River spill and the stuff had never run by these pipelines. Oops. A couple of days later, Reuters proved them mistaken—stunning each state and federal regulators. We nonetheless do not know what sort of tar sands oil was in that line. It is going to be interesting to find out if DilBit could have been concerned in that mess too.

As our January report on pipeline safety confirmed, pipelines transporting DilBit are at higher threat of busting. Alberta’s newer traces, designed to move this stuff, burst far more usually than American pipelines. But now that DilBit is coming with much larger frequency (Canadians used to partially refine it north of the border before sending it to us, however have maxed out that capability — we will probably be getting 1.5 million barrels a day of these items in the subsequent decade as deliveries ratchet up), so it is probably going that Kalamazoo will be a cleanup learning lab, gleaning information that shall be sadly an increasing number of necessary should our incident rates byproduct of oil refining crossword puzzle catch up with those in Canada. The Enbridge line that burst in Michigan was constructed within the 60s and not designed for the upper temperatures and pressure it was working at… which looks like an issue to me. However regulators do not have specific rules concerning this new and extra corrosive type of oil — so we are left with aging, ticking time bombs. As ugly as things are alongside the Kalamazoo, it might have been far worse had the oil hit Lake Michigan. And the identical pipeline runs by way of areas much closer to the Lakes. It appears time to revisit the best way we deal with these traces.
