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!

    Fish-Killing Virus Spreading in the Great Lakes – New York Times

    A virus that has already killed tens of thousands of fish in the eastern Great Lakes is spreading, scientists said, and now threatens almost two dozen aquatic species over a wide swath of the lakes and nearby waterways.

    The virus, a mutated pathogen not native to North America that causes hemorrhaging and organ failure, is not harmful to humans, even if they eat contaminated fish. But it is devastating to the ecosystem and so unfamiliar, experts said, that its full biological impact might not be clear for years. It is also having a significant impact on the lakes’ $4 billion fishing industry.

    There is no known treatment for the virus. As a result, scientists are focusing on managing its spread to uncontaminated water — quite a challenge since the Great Lakes are linked and fall under the jurisdiction of several states and provinces in Canada.

  • BC Carbon Tax regressive?

    British Columbians with low incomes will benefit from the carbon tax in its first year, but will pay more by the scheme’s third year, a new study concludes.

    The impact of the tax and its offsetting income tax cuts will become increasingly unequal unless the provincial government increases payments to low-income earners, the study says.

    The study, by Marc Lee, senior economist with the Canadian Centre for Policy Alternatives, and Toby Sanger, senior economist with the Canadian Union of Public Employees, takes a detailed look at the fairness of the controversial tax.

    via Carbon Tax Whacks the Poor, Later :: News :: thetyee.ca

    The report makes some good points. Revenue neutrality (the offsetting of carbon taxes with income/corporate tax cuts) has nothing to do with reducing carbon emissions. If I were to redesign this tax, I would do as the report says, increase rebates to lower income people, reduce corporate tax cuts so that the resulting revenue can be used to fund more transit infrastructure, energy efficiency infrastructure and the building of a low carbon economy.

    A carbon tax in itself is not sufficient to reduce emissions. It does its part, but building an energy efficient, low carbon infrastructure will do a lot more and the money’s there, just use it.

  • Bisphenol A Linked to Breast Cancer

    Chemical & Engineering News: Latest News – Bisphenol A May Trigger Human Breast Cancer

    Soto and her colleagues exposed pregnant rats to bisphenol A at doses ranging from 2.5 to 1,000 µg per kg of body weight per day. By the time the pups exposed at the lowest dose reached the equivalent of puberty (50 days old), about 25% of their mammary ducts had precancerous lesions, a proportion three to four times higher than among the nonexposed controls. Mammary ducts from all other exposure groups showed elevated levels of lesions. Cancerous lesions were found in the mammary glands of one-third of the rats exposed to 250 µg/kg/day.

    Bisphenol A is used in the manufacture of polycarbonate plastics and epoxy resins. It is found in many food and beverage containers, including baby bottles. It is also found in canned food linings and dental composites, and it leaches from all of these products. In one study, Soto notes, urine samples from 95% of the human subjects contained the chemical.

    The Environmental Protection Agency has set a safe human intake dose of 50 µg/kg/day for bisphenol A. “On the basis of the effects observed in recent studies, this seems to be an unsafe level,” Soto says.

    Bisphenol A is old news, BTW, people have known for a while about this chemical’s propensity to carcinogenicity. Of course, there’s that whole argument about pregnant mice being more susceptible to chemicals than humans, etc. So, the jury is still out. but Soto is right, 50 µg/kg/day seems to not provide enough of a safety factor. The EU uses 10 µg/kg/day, though they do say that

    realistic worst-case estimates of consumer exposure via foodstuffs, range from 0.00048 mg/kg bw/day for adults to 0.0016 mg/kg bw/day for infants, which is well below the maximum exposure level

    Of course, who knows what additive effects this chemical may have with the multitude of other chemicals floating around. Doing tests of single chemicals and trying to link that to epidemiological data is a perilous undertaking, the connections are tenuous most of the time and the plastics companies routinely fund studies that prove otherwise, because as you know, if you know what you’re going to find before you study it, you will find it!

    Read the wikipedia stub on polycarbonates. Us yuppies who drink religiously from Nalgene bottles to avoid phthalates and nasty tastes would do good to take note! I guess glass is the best, though it does have that annoying tendency to shatter when dropped… Water from glass bottles do have the best taste, though.

  • Industry flacks to write new EPA rules

    Now if I were a journalist, that is the tag line I would use, not the lame byline used in this article. Greater is always good, right!

    Greater Role for Nonscientists in E.P.A. Pollution Decisions – New York Times

    The Environmental Protection Agency has changed the way it sets standards to control dangerous air pollutants like lead, ozone and tiny particles of soot, enhancing the role of the agency’s political appointees in scientific assessments and postponing the required review by independent scientific experts.

    Now let’s see which famous “Industry advocacy group” may be behind this one…

    The change, which largely tracks the suggestions of the American Petroleum Institute but also adopts some recommendations of the agency’s independent scientific advisers, was announced yesterday afternoon by the agency’s deputy administrator, Marcus Peacock. Mr. Peacock said it would streamline a cumbersome process and bring it “into the 21st century.”

    Ah, the 21st century, where scientists know nothing and it is best for groups that will gain most from a weakening of legislation actually write the rules. This way, there’s no pesky “scientist” using “knowledge” to shape policy, only rules written for the short term gain of a few.

    It gets worse

    For one thing, agency scientists will no longer produce their own independent review of the latest science to start the process of deciding whether a pollution standard — for lead, say, or ozone — is tough enough to protect public health. Instead, initial reviews will now involve both agency scientists and their political bosses and will produce a synopsis of “policy-relevant” science, agency officials said.

    “They are using this idea of streamlined and expedited decision-making as a Trojan horse to infect the most important decisions the administrator makes with politics,” Ms. Patton said.

    In addition, she said, the role of the independent panel of scientific advisers — who act as auditors, reviewing the document produced by agency scientists and advising top management — has been diminished. The panel, the Clean Air Scientific Advisory Committee, will now comment on the agency’s proposed actions after the public has been notified of them, giving the scientists essentially the same kind of participation as industry lobbyists and environmental groups.

    (Emphasis mine). And they wonder why morale at the EPA is low. There are hordes of good (not great, but good!) scientists at the EPA who spend all their lives working on each of their scientific niches, and to take away any decision making or policy input from them is dehumanizing their work. Wonder why the EPA has a lot of trouble attracting talent.

  • Rolling Stone Magazine Expose' on the Pork Industry

    Excellent article, read in full, and let the next mass market pig you eat weigh on your conscience a little bit.

    I have attended meetings organized by the North Carolina Environmental Justice Network recently, and Smithfield foods is high on their agenda for the mind blowing pollution that overwhelmingly affects the poor and rural African-American communities, for their appalling safety record, and early American style treatment of its workers. See this PBS video for more. It is truly heartbreaking to hear testimony from people who live near hog farms, how the stench is overwhelming, omnipresent, and travels in your clothes and system wherever you go.

    Some Excerpts:

    Rolling Stone : Pork’s Dirty Secret: The nation’s top hog producer is also one of America’s worst polluters

    Smithfield Foods, the largest and most profitable pork processor in the world, killed 27 million hogs last year. That’s a number worth considering. A slaughter-weight hog is fifty percent heavier than a person. The logistical challenge of processing that many pigs each year is roughly equivalent to butchering and boxing the entire human populations of New York, Los Angeles, Chicago, Houston, Philadelphia, Phoenix, San Antonio, San Diego, Dallas, San Jose, Detroit, Indianapolis, Jacksonville, San Francisco, Columbus, Austin, Memphis, Baltimore, Fort Worth, Charlotte, El Paso, Milwaukee, Seattle, Boston, Denver, Louisville, Washington, D.C., Nashville, Las Vegas, Portland, Oklahoma City and Tucson.

    To appreciate what this agglomeration of hog production does to the people who live near it, you have to appreciate the smell of industrial-strength pig shit. The ascending stench can nauseate pilots at 3,000 feet. On the day we fly over Smithfield’s operation there is little wind to stir up the lagoons or carry the stink, and the region’s current drought means that lagoon operators aren’t spraying very frequently. It is the best of times. We can smell the farms from the air, but while the smell is foul it is intermittent and not particularly strong.Unsurprisingly, prolonged exposure to hog-factory stench makes the smell extremely hard to get off. Hog factory workers stink up every store they walk into. I run into a few local guys who had made the mistake of accepting jobs in hog houses, and they tell me that you just have to wait the smell out: You’ll eventually grow new hair and skin. If you work in a Smithfield hog house for a year and then quit, you might stink for the next three months.

    Epidemiological studies show that those who live near hog lagoons suffer from abnormally high levels of depression, tension, anger, fatigue and confusion. “We are used to farm odors,” says one local farmer. “These are not farm odors.” Sometimes the stink literally knocks people down: They walk out of the house to get something in the yard and become so nauseous they collapse. When they retain consciousness, they crawl back into the house.

    Successful Farming magazine warned — six years ago. There simply is no regulatory solution to the millions of tons of searingly fetid, toxic effluvium that industrial hog farms discharge and aerosolize on a daily basis. Smithfield alone has sixteen operations in twelve states. Fixing the problem completely would bankrupt the company. According to Dr. Michael Mallin, a marine scientist at the University of North Carolina at Wilmington who has researched the effects of corporate farming on water quality, the volumes of concentrated pig waste produced by industrial hog farms are plainly not containable in small areas. The land, he says, “just can’t absorb everything that comes out of the barns.” From the moment that Smithfield attained its current size, its waste-disposal problem became conventionally insoluble.

    Nice, huh! Still eating factory pork?

  • Sethusamudram – A typical Indian development project

    The Sethusamudram (bridge sea – for the transliterators) project has the classic development plot lines that I’ve seen play out many times in India. Here’s a rationale from the official site…

    Currently the ships coming from the west coast of India and other western countries with destination in the east coast of India and also in Bangladesh, China etc have to navigate around Srilankan coast. The existing water way is shallow and not sufficient for the movement of ships. This is due to the presence of a shallow region known as Adam’s bridge, located southeast of Rameswaram near Pamban, which connects the Talimannar Coast of Srilanka

    What? They are going to destroy the bridge that rama and the vanaras built? Look at that picture, (thanks Manitham), can’t you see all the “Vanaras” (this has always struck me as racist – folks showing up from the North and calling the darker skinned Southerners Monkeys! But that is a different rant) running across the very clearly delineated land bridge – It’s fascinating, almost makes me believe that the Ramayana happened as narrated!

    Manitham has a good rundown of the project from an activist standpoint.

    A few points

    • The secrecy and lack of transparency are classic government techniques to control the flow of information and discourse. Every government does it, and the Indian government is no exception.
    • Environmental Impact Assessments are bought and paid for by the funding agency, and are hence essentially unreliable and untrustworthy. I had first hand experience of this when I was a student at IIT Bombay 10 years back.
    • There is a lot of politics involved, the port of Tuthukudi (Tuticorin as the damn Brits say) in Tamil Nadu is a clear winner and Colombo in SriLanka stands to lose revenue. There is also a great deal of Tamil Pride involved
    • Read this excellent article from the climate.lk clearinghouse of articles : There is a security dimension here for India that may have been the actual motivation.
    • The area, due to its sheltering and shallow waters, has a lot of marine life. From a 2004 Deccan Herald Article

    The series of meetings called by the Tuticorin Port Trust chairman in the coastal districts have turned out to be stormy with representatives of political parties shouting down objections from fishermen, who fear the loss of livelihood, and environmentalists who say the project threatens to destroy the Gulf of Mannar Marine Reserve. This reserve is one of India’s most biologically diverse coastal regions.
    Over 3,600 species of plants and animals are found here. It is the first marine biosphere reserve in the South and South-East Asia and is believed to have the highest concentration of seagrass species along India’s coast. It is also among the largest remaining feeding grounds for the globally endangered species dugong. Five different species of endangered marine turtles, innumerable fish, molluscs and crustaceans are also found here. The Bombay Natural History Society (BNHS), the largest NGO working in the field of bio-diversity and environmental conservation, has said the rapid Environmental Impact Assessment (EIA) report prepared by the National Environmental Engineering Research Institute (NEERI) is insufficient and a detailed study should be conducted in all seasons for at least a year.

    • The EIA actually says that since the seaway is 20 km away from the reserve, there will be no effect on the reserve, um, that seems highly unlikely to me…
    • The other major dimension is the usual utter lack of care for the people displaced. previous instances like the Sardar Sarovar project indicate that there will be no fair compensation for the displaced people, or for lost livelihood, which I guess is perfectly fine because it serves the greater good of the country?

    Most of these big projects have resulted in overstated gains, understated losses, and huge wastes of taxpayer money. I don’t trust this to be any different. The facts look fudged, the project seems unnecessary (where’s my tamil pride?) and the effect on the wildlife and the crazy complex current system around Sri Lanka may change significantly leading to unforseen micro climate effects.

    Two thumbs down…
