It’s been three weeks since we left New Orleans, and while things change, it seems little has changed. BP is coming closer and closer to the truth in reporting the flow rate of the underground leak. NOAA has confirmed the presence of widely dispersed subsurface oil plumes, but with the few vessels they have, it will take a while to get a good estimate for the quantity of that oil. Plaquemines parish is getting absolutely thromped by encroaching oil slick. As the crude works its way into the coastal marshes, the remaining hurricane protection provided by them becomes even more precarious. In a twist of fate, the network of oil pipelines and infrastructure in the marshes already endangered by changes in silt deposition patters of the delta, are further jeopardized by the death of the native wetlands (http://news.nationalgeographic.com/news/2010/05/100525-gulf-oil-spill-pipelines-science-environment/). The loss of the bayou to the sea is bound to leave a watery world even more watery, the bayou has always been barely above the sea, miles and miles of marshland are all that the eye can see, where oil rigs and raised houses are often the only relief in the landscape.
The initial images available through google have become sparser as MODIS quality images have been hard to get. The slick has danced back and forth, washing over the Grand Isle area and swinging to the Alabama coast. Nobody knows what the long term consequences will be in particular, but its sure to be devastating. It’s pretty much assumed that BP’s rationale behind using massive amounts of the toxic dispersant Corexit was to minimize the visibility of the spill, including allegations of providing profits for some of its own subsidiaries. One thing is for certain, the flow of the underwater leak is at least 15,000 a day, and easily double, or triple that; nobody ‘legitimate,’ a term that has become increasingly loaded, seems to have anything definitive. The independent assessments made by Prof. Wereley at Purdue University, using particle tracking on video provided by BP (source NPR), of a 40,000 to 90,000 barrel a day range now seem the most appropriate. Given the variability in flow and natural gas composition, its hard to get an exact number, but given the seeming unstoppability of the leak, and BP’s continued ability to extract marketable raw petroleum, it seems they tapped into something way bigger than they were technologically able to handle, much less control in the face of disaster.
An increasingly disturbing phenomenon, dead, un-oiled wildlife has been washing up on gulf beaches. And that is just the tip of the iceberg. Both Corexit 9500 and 9527 (the older ‘more’ toxic version) have been banned in the UK due to their acute toxicity to all levels of animal life in the marine food chain. The Material Safety Data Sheets (MSDS sheets required under federal law commercially available chemical substances) for Corexit list its acutely toxic effects as causing damage to the central nervous system, and chronic exposure can cause kidney, liver and red blood cell damage. Corexit 9527 contains between 30-60 % butoxyethanol (otherwise known as ethylene glycol mono-butyl ether), similar to pure ethylene glycol which has been discontinued for use as an antifreeze due to its danger to human health. A peer reviewed study from the Journal of Ecotoxicology and Environmental Safety authored by Michael Singer and others (1996), showed no significant difference between Corexit 9500 and 9527 in terms of its acute toxicity, measured by LD50 (Lethal Dose at which 50% of the test organism dies), in controlled laboratory experiments. The fact that the MSDS sheets for Corexit 9500 do not include these data (they state that no ecotoxicological studies have been performed) also seems a bit fishy.
What to do then? BP’s PR oriented response, and the slowness of its final ‘effective’ response, in terms of drilling relief wells which will allow plugging the original leaking well, displays dangerous ineffectiveness of the regulation of these companies. How is it, that in Norway, where deep water drilling is a common practice, companies are required to drill a relief well before oil extraction can take place? Also, how is it that these dispersants are banned in the EU? The wild cat era of oil exploration in the States aside (an era where development rights fell to the discover of ‘black gold’ with little or no government regulation), it seems we are teetering on the edge of a global crisis in terms of the lack of regulation on a highly destructive extractive industry.
The little publicized fight of indigenous peoples seeking reparations from Texaco’ (now Chevron’s) oil drilling operations in the Ecuadorian rain forest (http://chevrontoxico.com/) is also signals our failure as a market (a role secondary to that of Americans, or any nationality for that matter, as a people, a fact that we often forget) to demand minimal environmental and social standards for companies that sell their wares in the US. Likewise, oil drilling in the Niger Delta (a significant percentage of which is managed by Shell Petroleum), has led to an estimated 100 million barrels of oil being leaked between 1960 and 2000 (http://en.wikipedia.org/wiki/Environmental_issues_in_the_Niger_Delta), an amount approximately twice the middle of the road estimate (3 million gallons a day) of the to date estimate (July 7th) for the Deep Horizon spill. Many local people in the Niger Delta have joined or are in support of a loose coalition, or ‘idea’ known as the Movement for the Emancipation of the Niger Delta (MEND), a militant organization that often kidnaps foreign oil company workers and ransoms them, though their connection between hijackers of pipelines is not clear in the general chaos of the delta (an evolving story on the current state of the conflict can be found here: http://www.pambazuka.org/en/category/features/38005 and here: http://www.dawodu.com/okonta2.htm)
As a species, we tend to focus on the real visceral consequences of environmental disasters, earthquakes, oil spills, volcanic eruptions, burning rivers etc… But even when these visceral examples exist, of blatant mismanagement resulting in environmental and social catastrophe, why does so little change? Is the old Dead Kennedy’s maxim, give me convenience or give me death, more powerful than any existing sense of social ethics? Could we really have become so crass as to ignore the environmental and social damages associated with fossil fuel extraction, and mining of many types, or can we blame the lack of well-publicized information of our inaction? Has the mythos of the necessity of constant economic expansion so pervaded the social consciousness that is simply not cool or valuable to care about where the raw materials of the economy come from?
In the Yellow Emperor’s Classic of Internal Medicine he writes on the efficacy of three brother physicians: “the first brother would often leave his province to perform complicated surgeries on great rulers, his name was known throughout the kingdom and he was thought of as a great physician. The second brother prepared herbal concoctions and potions, and would practice acupuncture on imbalanced people to prevent the acute emergence of disease, he often left the house in his work and reached some renown in the town and province. As for the third brother, he sought harmony in his own life so as to prevent the disease far before its emergence, through wu wei (which can be interpreted as action at a distance, or as correct living, or both) he kept the healthy healthy, no one knew his name.” Our sense of drama attracts us to disaster, and it is difficult to praise those, or even find those, that keep us out of disaster that is not yet visible to the human psyche. Oddly enough routine discharges of oil from its consumption (including land based consumption and refinery losses) is on average three times more than any accidental discharge of oil (http://oils.gpa.unep.org/facts/sources.htm). This little known fact says something important about our psychology of disaster. The scarier thing is the uncertainty associated with the NRC estimates, their total range being 3,431,000 to 61,320,000 barrels of oil discharged into the sea yearly. Even though these discharges are distributed throughout the oceans, they contribute significantly to the general stress of the oceans via agricultural runoff, dumping of toxic waste, human waste, household trash, you name it, not to mention overfishing, nursery destruction and alterations to patterns of fresh water inputs to estuarine systems, the damages read like a litany.
At its current lower end estimate, the spill is approaching .5% of our 19,498,000 barrels/day national oil usage. Our motor gasoline usage in the states, amounts to some 8,989,000 barrels/day. The amount of refinable gasoline in a barrel of crude runs from 5 to 28 gallons on average (remember a barrel is 42 gallons), the rest being used to produce various needed organic molecules and other industrial products. Secondary refining is the bread and butter of much of the region that spans far eastern Texas to New Orleans.
Driving to a beach north of Malibu, we used up maybe 5 gallons of gas, or about 1/8th of a barrel of gas. On the way back we were in stop and go traffic for upwards of an hour, the gasoline fumes rising around us as fuel efficiency dropped precipitously. Earlier, at the beach, I uncovered a small pancake of of tar, which according to a friend of mine, is a phenomenon becoming more common in recent weeks on the LA beaches. It could be he’s just started to notice them more, or the spill in the gulf intensified drilling activities on the California shelf, in either case it is there, the palm sized sticky spot on the beach having washed in from far out to sea.
