Methane Leakage, again

In a sane world, we would be very concerned about measuring, reporting and closely regulating methane releases during its extraction and processing, especially if we claim that it is clean energy. This is nothing I, or other people haven’t said before, but here’s more research summarized in the very respectable Nature Journal indicating that measurable leak rates of methane can vary widely.

Preliminary results from a field study in the Uinta Basin of Utah suggesting even higher rates of methane leakage — an eye-popping 9% of the total production. That figure is nearly double the cumulative loss rates estimated from industry data — which are already higher in Utah than in Colorado

10% is a large number. I’ve posted this picture from Wigley (2011) previously. At any leakage rate other than zero, which no one claims, the benefits of switching from coal to methane are very modest.

It's all about Methane leakage
It’s all about Methane leakage
We absolutely need to measure, control and regulate fugitive methane emissions from every BC site, and need to have solid regulation in place before we keep expanding natural gas infrastructure. We need our political leaders to start talking seriously about capturing methane leaks when they talk about BC’s natural gas “play”.

  • Au Revoir, Clean Water Act?

    Just like that, the Supreme Court chips away at one of the foundations of this country’s Environmental Law.
    Court Splits Over Wetlands Protections – New York Times

    By DAVID STOUT. WASHINGTON, June 19 — The Supreme Court set the stage for a re-examination of the 1972 Clean Water Act, as it narrowly ruled today in favor of two Michigan property owners who have sought to develop tracts designated as wetlands.

    By 5 to 4, the justices overturned lower court judgments against the Michigan land owners, who had run afoul of the Clean Water Act over their plans to build a shopping mall and condominiums.

    The ruling was not the resounding, unambiguous triumph that the land owners, John A. Rapanos and June Carabell, may have hoped for. Instead, five justices found that regulators may have gone too far in trying to thwart their plans, and it returned the case to lower courts for further deliberation. One of the five justices, Anthony M. Kennedy, even suggested in a separate opinion that the property owners might lose once again in the lower courts.

    I was very afraid when I last thought about this challenge way back in February. It was pretty clear at that point that Kennedy was the swing vote and that 8 out of 9 minds were probably made up. Kennedy’s lawmaking seems to be a little incoherent in this case. He was obviously not comfortable with the Scalia-Alito-Roberts-Thomas cabal’s clearly ideological decision, but can’t bring himself to make the centrist decision.

    But Justice Kennedy wrote that the evidence in the long-running Rapanos and Carabell cases suggests “the possible existence of a significant nexus,” or connection, between their properties and navigable waterways — a connection that, if established in the lower courts, would reaffirm the jurisdiction of the Clean Water Act over the tracts and could cause the property owners to lose again.

    If you thought that there was a “significant nexus”, what kind of logic would then make you turnaround and support the opinion that there is no connection?

    But Justice Scalia had a different perspective as he questioned the extent of federal jurisdiction. Under the government’s logic, he said, “a storm drain, even when not filled with water, is a tributary.”

    “I suggest it’s very absurd to call that ‘waters of the United States,’ ” Justice Scalia added. “It’s a drainage ditch.”

    Where Hon. Justice Scalia pretends to misunderstand the concept of drainage? I wonder if he would feel the same way if it was a pollution issue in his neighbor’s backyard.

    This will make things confusing for a while, and you all know who confusion favors!

  • EU outpaces United States on Chemical safety

    Dog bites man news o’ the day!

    ScienceDaily: European Union Outpaces United States On Chemical Safety

    In the 1970s and ’80s, the United States effectively set many global product standards for consumer and environmental protection. Today, Europe is playing this role, while U.S. government and industry oppose the resulting standards in Europe and in international arenas.

    The size of the European market (more than 485 million citizens) will push manufacturers in the United States and Asia to meet European standards and will increase the availability of “green” products globally, contend the authors. Additionally, the new toxic risk information generated by REACH may allow environmental advocates in the United States and elsewhere to focus their efforts with specific, supportable data.

    Amen to that, you can either lead, or be forced to follow. EU policies are far from perfect, and as vulnerable to politics, hypocrisy and competing interests as any other “country’s” policies. But, you can never fault them for lack of effort, and they do not seem to have suffered from any consequences to using the precautionary principle.

    When an activity raises threats of harm to the environment or human health, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically.

    Not so hard to grasp. But here’s the precautionary principle the US of A uses. I propose calling it the plutocracy-protectionary principleTM.

    When a proposed regulation raises threats of harm to the short term shareholder returns of an industry, precautionary measures to oppose this regulation must be taken even if cause and effect relationships are clearly established, or if scientific research has shown the opposite effect to the industry claim being made.

    Organic agriculture can feed the world

    That’s the conclusion reached by the authors of this study based on 293 examples in the developing and developed world.The authors also conclude that yields in the developing world are higher for organic agriculture than for conventional agriculture. Why? Well, since the paper is not open access, I can’t read it, or critique it, I’ll have to wait to get to the library before I can download it. But, maybe it’s because organic agriculture tends to be more labor intensive than conventional agriculture as practised by the developed world, and in the developing world, labor is cheap!

    Anyway, this is a good news study and should be examined a little more thoroughly.

    CJO – Abstract – Organic agriculture and the global food supply

    The principal objections to the proposition that organic agriculture can contribute significantly to the global food supply are low yields and insufficient quantities of organically acceptable fertilizers. We evaluated the universality of both claims. For the first claim, we compared yields of organic versus conventional or low-intensive food production for a global dataset of 293 examples and estimated the average yield ratio (organic:non-organic) of different food categories for the developed and the developing world. For most food categories, the average yield ratio was slightly 1.0 for studies in the developing world. With the average yield ratios, we modeled the global food supply that could be grown organically on the current agricultural land base. Model estimates indicate that organic methods could produce enough food on a global per capita basis to sustain the current human population, and potentially an even larger population, without increasing the agricultural land base. We also evaluated the amount of nitrogen potentially available from fixation by leguminous cover crops used as fertilizer. Data from temperate and tropical agroecosystems suggest that leguminous cover crops could fix enough nitrogen to replace the amount of synthetic fertilizer currently in use. These results indicate that organic agriculture has the potential to contribute quite substantially to the global food supply, while reducing the detrimental environmental impacts of conventional agriculture. Evaluation and review of this paper have raised important issues about crop rotations under organic versus conventional agriculture and the reliability of grey-literature sources. An ongoing dialogue on these subjects can be found in the Forum editorial of this issue.

    DuPont sets goal of eliminating Teflon processing chemical

    See, it wasn’t too hard to come up with safe alternatives, improved processes and a decent timeline!

    DuPont sets goal of eliminating Teflon processing chemical

    One year after accepting a government challenge to work toward eliminating the use of a potentially dangerous chemical used to make Teflon and other products, the DuPont Co. said Monday it plans to stop using the chemical by 2015.

    The Environmental Protection Agency asked the Wilmington-based chemical giant and seven other companies last year to commit to a 95 percent reduction in environmental emissions and product content levels of perfluorooctanoic acid, or PFOA, and associated chemicals by 2010.

    DuPont makes the chemical at a plant near southeast Ohio in Parkersburg, W.Va.

    The companies also were asked to work toward the elimination of PFOA and associated chemicals from emissions and products by 2015.

    On Monday, DuPont said technological advances have allowed it to remove more than 97 percent of trace levels of PFOA and associated chemicals from surface protection fluorotelomers used in products such as oil-resistant paper packaging and stain- and water-repellent textiles.

    DuPont also has been able to reduce PFOA content by at least 97 percent in fluoropolymer coatings used in Teflon cookware, architectural coatings and electronics applications.

    “We have been working for a long time, but particularly over the last year, on alternative technologies to PFOA,” said David Boothe, business manager for DuPont fluoroproducts. “We believe that work is going to allow us to eliminate the need to make, buy, or use PFOA by 2015… That’s firmer language than ‘work toward.'”

    For previous posts on this subject, see here. Who says a little pressure doesn’t help change even the all powerful Dupont!

    Virus Implicated In Colony Collapse Disorder In Bees

    This is a potentially important find, but as usual, I feel the need to stress that at this point in time, as the scientists did too, that they correlated the presence of this virus with the prevalence of Colony Collapse Disorder. It is likely that this virus, while being a contributing factor, is not the only cause. Other contributors may include stress, the fact that these bee hives are transported thousands of miles, etc.

    But, great detective work by this collaborative team of academics, American government scientists and one for-profit company.

    ScienceDaily: Virus Implicated In Colony Collapse Disorder In Bees

    A team led by scientists from the Columbia University Mailman School of Public Health, Pennsylvania State University, the USDA Agricultural Research Service, University of Arizona, and 454 Life Sciences has found a significant connection between the Israeli Acute Paralysis Virus (IAPV) and colony collapse disorder (CCD) in honey bees.

    The findings, an important step in addressing the disorder that is decimating bee colonies across the country, are published in the journal Science.

    In colony collapse disorder, honey bee colonies inexplicably lose all of their worker bees. CCD has resulted in a loss of 50-90% of colonies in beekeeping operations across the U.S.

    I was just thinking I should check on the progress of scientists towards finding a cause for this issue, seems like I did not have to!

  • Coal is Evil, part 1201010

    Note: When people say “clean coal”, they are referring in part to all the actions taken to limit particle and ash emissions out of the smokestacks. This is done in a variety of ways including washing the coal to remove inorganic ash components, trapping the particles using electrostatic precipitators, etc. What this leaves you with is very toxic coal ash, and very toxic acidified water loaded with the coal wastes it was used to remove.

    Now you can pretend that this is somehow cleaner, and it is, to an extent, because you have concentrated the pollution by isolating it and not letting it disperse into the atmosphere. However, if you then dump the waste into unlined landfills, you completely defeat the whole point of the exercise. This very extensive report written by the Clean Air Task Force and Earth Justice looked at streams in Pennsylvania and found a ton of heavy metal pollution.

    Coal is neither cheap, nor clean if you have to deal with all the pollution and pay for it, and we did not even have to get to that whole other pollutant, CO2!

    <Pennsylvania Groundwater Contaminated By Coal Ash

    Disposing of coal ash in mines is contaminating water supplies throughout Pennsylvania, according to a report released today by the advocacy group Clean Air Task Force and the nonprofit, public interest law firm Earthjustice.

    In 10 of 15 mines examined across the state, groundwater and streams near areas where coal ash, or coal combustion waste, was placed had levels of arsenic, lead, cadmium and selenium and other pollutants above safe standards.

    ‘Disposing of coal combustion waste in these mines is threatening water supplies all over the state,’ said Jeff Stant, director of the Pennsylvania Minefill Research Project at the Clean Air Task Force. ‘If the Pennsylvania Department of Environmental Protection won’t act now to stop these dangers, the U.S. EPA should step in to protect the residents of Pennsylvania who live near coal ash mine fills.’

    The Pennsylvania Department of Environmental Protection has refered to the ‘beneficial use’ of coal ash in these active and abandoned mines, claiming that the practice limits the outflow of acidic water from mines.

    This study found the opposite was true – in six of the nine permits that used coal ash to treat acid mine drainage, acidity levels increased, leaving the mines more acidic at the end of monitoring.
