Oil refineries underestimate release of emissions, study says

A study by the Alberta Research Council that investigated the plume of contaminants emanating from a Canadian oil refinery using high-tech sniffing equipment found the facility dramatically underestimated its releases of dangerous air pollutants.The refinery, which wasn’t identified but is believed to be in Alberta, released 19 times more cancer-causing benzene than it reported under Environment Canada disclosure regulations, about 15 times more smog-causing volatile organic compounds, and nine times more methane, a greenhouse gas, according to the study.The testing is believed to be the first at a North American refinery using the sophisticated technology relying on lasers, and is considered state-of-the art. The technology, developed by British Petroleum, has been in widespread use in Europe for nearly two decades.

globeandmail.com: Oil refineries underestimate release of emissions, study says

Serious stuff, this. As the report points out, this is old news, here’s a workshop report from the EPA last year about this very issue (no, don’t read it, 303 pages long). Volatile organic compounds are inputs into air pollution models that measure ozone levels. When your local agency tells you that Tuesday is going to be a code orange ozone day, they rely on ozone models such as CMAQ. Now, without proper inputs, you are going to make some serious errors in prediction. These errors are somewhat mitigated by the tuning of these models with measured concentrations. So, there is some error compensation going on within the model.

More importantly, by underestimating fugitive emissions, refineries can reduce their leak monitoring, reporting and mitigation costs. There is also the issue of conflict of interest here. The current technique was developed by the American Petroleum Institute!

Do we expect measurement based techniques to start being used in the US and Canada? One would hope so, but, don’t hold your breath!

    Canada’s greenhouse emissions soaring: UN report

    The figures are based on the 2009 national inventory report that Environment Canada quietly filed last week with the United Nations to meet its international reporting obligations. The full 673-page inventory is available on the UN’s website and shows Canada has the dubious distinction of having its emissions climb more since 1990 than any other G8 nation.

    Canada ranks “first among the G8 nations” for increasing emissions, the report notes, even though Canada had committed to cut them. It notes that while Canada’s emissions have soared, Germany chopped its emissions by 18 per cent between 1990 and 2006, and the United Kingdom slashed its by 15 per cent.

    Hey, we’re first in the G8 in something! The increase was driven primarily by increasing Tar Sands emissions thanks to the oil boom. Cars and coal also contributed.

  • Canada's Environmental Corpus Callosum malfunction

    One of my first impressions on moving to Victoria was the high environmental consciousness of the people here. The obvious markers of environmental consciousness such as recycling, composting, organic food consumption, local food consumption, small car driving, and most importantly, pride at being environmentally conscious are off the charts here  (and I am  most definitely  one of those people as well!).

    My second impression was that a country with such a resource driven economy can’t possibly live up to what its citizens think it is doing. And I was right. The country as a whole performs abysmally. Canada vs. the OECD (a report produced by my very hometown University of Victoria) compares Canada’s performance vs. the OECD on a number of environmental parameters. It is shocking. The picture is painted of an inefficient economy whose consumption of major resources and pollution indicators are growing at a time they should be dropping. For example:

    Canada is among the three worst countries on nine indicators (per capita greenhouse gas emissions, sulphur dioxide emissions, carbon monoxide emissions, volatile organic compound emissions, water consumption, energy consumption, energy efficiency, volume of timber logged and generation of nuclear waste);

    Canada’s economy is inefficient, in that we use much more energy and generate much more pollution to produce a given amount of goods and services relative to our industrial competitors, including 33% more energy than the United States per unit of GDP; and

    Canada’s performance on most environmental indicators continues to worsen

    So, not only are things bad, they’re getting worse, but the people don’t seem to notice. Massive corpus callosum1 malfuction?

    BTW, this is what happens to people when their corpus callosum is removed.

    Once this theme crystallized in my head, I went searching for earlier work that would reinforce my conclusion and came upon this book Unnatural Law – Rethinking Canadian Environmental Law and Policy. From the First chapter:

    Is Canada an environmental leader or an environmental laggard? Is Canada contributing to solving environmental challenges or are we exacerbating these problems?

    Great, a book that reinforces my frame in the very first paragraph! I’ll let you know after I finish reading the book (helpfully available from my local library and written by a former ED for the SIerra Legal Defence Fund (now known as Ecojustice) and who lives on Pender Island, a few islands away from where I live! Promises to be an interesting and illuminating read.

    Jeffrey Sachs on climate change induced water shortages

    Depressing reading for a Sunday morning. He does not offer too many solutions, but it will take a lot of local work to mitigate these disasters. Of course, I can’t see the US or Europe offering asylum to climate change refugees!

    Climate Change Refugees: Scientific American

    Human-induced climate and hydrological change is likely to make many parts of the world uninhabitable, or at least uneconomic. Over the course of a few decades, if not sooner, hundreds of millions of people may be compelled to relocate because of environmental pressures.

    To a significant extent, water will be the most important determinant of these population movements. Dramatic alterations in the relation between water and society will be widespread, as emphasized in the new report from Working Group II of the Intergovernmental Panel on Climate Change. These shifts may include rising sea levels, stronger tropical cyclones, the loss of soil moisture under higher temperatures, more intense precipitation and flooding, more frequent droughts, the melting of glaciers and the changing seasonality of snowmelt.

  • Plastic Bag Use – Money Talks

    In 2002, Ireland passed a tax on plastic bags; customers who want them must now pay 33 cents per bag at the register. There was an advertising awareness campaign. And then something happened that was bigger than the sum of these parts.Within weeks, plastic bag use dropped 94 percent. Within a year, nearly everyone had bought reusable cloth bags, keeping them in offices and in the backs of cars. Plastic bags were not outlawed, but carrying them became socially unacceptable — on a par with wearing a fur coat or not cleaning up after one’s dog.

    Motivated by a Tax, Irish Spurn Plastic Bags – New York Times

    Turns out that you can swiftly alter habits, attitudes, perception and behavior by charging people 33 cents per bag! Plastic bags are a convenience only because they are free.

    Also, if you read the entire article, you will realize that ad-hoc, voluntary, or piecemeal approaches by individual retailers, cities or states will not make as much of an impact as a national policy.

    All hail Ireland!

  • Virulent E-Coli strain lives in grain-fed cattle.

    Interesting side note about the spinach E-Coli outbreak

    Leafy Green Sewage – New York Times

    Where does this particularly virulent strain come from? It’s not found in the intestinal tracts of cattle raised on their natural diet of grass, hay and other fibrous forage. No, O157 thrives in a new — that is, recent in the history of animal diets — biological niche: the unnaturally acidic stomachs of beef and dairy cattle fed on grain, the typical ration on most industrial farms. It’s the infected manure from these grain-fed cattle that contaminates the groundwater and spreads the bacteria to produce, like spinach, growing on neighboring farms.

    Well, talk about unforeseen consequences, cows really should not eat grain. Go watch my favorite food cartoon ever, the Meatrix, and its most excellent sequel, The Meatrix 2: Revolting for more.

    When cows were switched from a grain diet to hay for only five days, O157 declined 1,000-fold. This is good news. In a week, we could choke O157 from its favorite home — even if beef cattle were switched to a forage diet just seven days before slaughter, it would greatly reduce cross-contamination by manure of, say, hamburger in meat-packing plants.

    Seems easy enough to implement, if impossible to enforce.

    Update

    A more nuanced look, if not a debunking of the above theory can be found on this scienceblogs page.

    Coffee Roasting and Popcorn Lung

    Cross-posted from Interrobang

    Who among us coffee drinkers don’t love the smell of freshly roasted coffee? I am sure some of us imagine how much fun it would be to smell freshly roasting coffee more often. I don’t, because smell for me is an instant jolt of pleasure/pain followed by a rather rapid decline into the background.

    Caution, though. New measurements from the US Centres for Disease Control warn of high exposure to some pretty nasty chemicals that can cause your lungs to be destroyed irreversibly, the unfortunately named “popcorn lung” or bronchitis obliterans:

    Investigators with the National Institute of Occupational Safety and Health, a research arm of the CDC, spent several days at Madison-based Just Coffee in July. Investigators tested personal air space and took air samples to measure the concentration of the chemicals diacetyl and 2,3-pentanedione… NIOSH researchers found levels in three breathing-zone samples that exceeded the safety levels recommended by the CDC.

    Coffee Roasting Plants and Exposure

    The test results show a marginal exceedance in this case, but noted that ventilation is a big factor and these tests were done under well ventilated conditions on a warm and dry day when doors were open. So, exposure can be higher in other circumstances.

    Worker exposures are to higher levels, and are more sustained, so they deserve the most attention.

    So, local coffee roasters, it may make sense to confirm that your roasting environments are not exposing your workers to harmful, lung obliterating chemicals. Remember, organic, shade grown, fair pay, artisanal roasting aside, chemical exposures to workers don’t change. And, everything that smells good isn’t good for you.

    One of my frequent points of emphasis (rants, some might say) is on the relative risk vs. media attention to exposures of people to ambient, day to day concentrations of potential harmful chemicals vs. those faced by workers everywhere. The last time diacetyl and bronchitis obliterans were in the news, it was around the use of diacetyl to produce that buttery smell so beloved in microwave bag popcorn (I don’t like it myself, olive oil all the way!). Despite reports of many workers facing severe lung issues, it took the detection of the disease of one person eating multiple bags of microwave popcorn over many years to actually move government regulators into action on diacetyl. People who work in factories, in the fields, and make things are exposed to thousands of times higher concentrations of harmful chemicals for longer periods of time, but their concerns are often de-emphasized.

    This doesn’t mean ambient exposures in the general population are to be ignored, but worker exposures are to higher levels, and more sustained, so they deserve the most attention.

    16-May-2016 Update

    This US Centers for Disease Control page is a good collection of information and further readings. They recommend facility tests to measure diacetyl and its cousin 2,3-pentanedione, and better ventilation, worker safeguards and personal protective equipment as necessary. They also note that at least five workers in large scale coffee processing plants have been diagnosed with bronchitis obliterans.
