EPA Calls for End to Releases of Chemical in Teflon Process

Check out this story from the January 26, 2006 LA Times.

In a rare move to phase out a widely used industrial compound, the Environmental Protection Agency announced Wednesday that it was asking all U.S. companies to virtually eliminate public exposure to a toxic chemical used to make Teflon cookware and thousands of other products.

EPA’s system of regulating chemicals leads to some really perverse incentives. The burden of proof shifts to the EPA to prove beyond reasonable doubt that a chemical has definite harmful effects on humans at ambient exposure levels. So the preferred route has been for the EPA to “suggest” to the companies to participate in a voluntary phaseout.

No one knows how the chemical is getting into people’s bloodstreams and in the bodies of polar bears and other animals. Although it is used in production of cookware, it is not found in the cookware, clothing and other fluoropolymers after manufacture.

Well, not quite. This from a paper published in the Environmental Science and Technology on January the 25th.

Polyfluorinated telomer alcohols and sulfonamides are classes of compounds recently identified as precursor molecules to the perfluorinated acids detected in the environment. Despite the detection and quantification of these volatile compounds in the atmosphere, their sources remain unknown. Both classes of compounds are used in the synthesis of various fluorosurfactants and incorporated in polymeric materials used extensively in the carpet, textile, and paper industries. This study has identified the presence of residual unbound fluoro telomer alcohols (FTOHs) in varying chain lengths (C6-C14) in several commercially available and industrially applied polymeric and surfactant materials…

This study suggests that elimination or reduction of these residual alcohols from all marketed fluorinated polymers and fluorosurfactants is key in reducing the prevalence of perfluorinated acids formed in the environment.

Well, that explains it a little better, this article from ES&T provides a nice executive summary like context.

An emerging theory that explains how PFOA (perfluorooctanoic acid) and other PFCAs (perfluorocarboxylic acids) have contaminated the Arctic has received a boost from a new modeling study published in this issue of ES&T (pp 924–930). The theory contends that Arctic contamination is due to atmospheric transport and breakdown of fluorotelomer alcohols, chemicals that are used in products that include stain protectors, microwave-popcorn bags, fast-food wrappers, polishes, and paints.

Well, it sure looks like we need to focus much more on the PFOA precursors rather than on the PFOA itself. Dupont and 3M are not going to be happy about that!

    Chemical agency ties under review – Los Angeles Times

    As I mentioned a couple of days back, Sciences International has some conflicts of interests in this bisphenol A issue. I am glad that NIEHS is taking note.

    Chemical agency ties under review – Los Angeles Times

    The National Institute of Environmental Health Sciences has begun a review of ties between a federal health center that evaluates the risks of chemicals to reproductive health and a consulting firm funded by companies that produce chemicals linked to reproductive disorders.

    The investigation follows a Times report on Sunday that Sciences International, an Alexandria, Va., firm funded by more than 50 industrial companies, helps manage the federal Center for the Evaluation of Risks to Human Reproduction.

    Among the firms with financial ties to Sciences International are two that produce bisphenol A, a chemical in polycarbonate plastic bottles that has been linked in animal testing to prostate and breast cancer and reduced fertility.

    Since 1998, Sciences International has helped manage the federal reproductive health center and prepared draft reports analyzing bisphenol A and 16 other chemicals. The company has a $5-million contract with the center.

    The center’s scientific advisory panel was scheduled to decide today whether bisphenol A endangers reproductive health in humans.

    But on Tuesday, director Michael Shelby announced that the panel, after two days of reviewing the 372-page report that Sciences International prepared on bisphenol A, known as BPA, still had too many unresolved questions and was postponing its decision for six weeks.

    Good investigative journalism still makes a big difference.

    As always, as I was writing this post, I noticed that the ever excellent folks at the pump handle read my mind and posted about it (2nd time in 3 days!), so I will stop writing (and thinking about Bisphenol A) and direct your attention to their post!

  • Doom and Gloom on Canadian Climate Change Report

    “The conclusions [the report] draws are irresponsible,” said Mr. Prentice in an interview with The Globe and Mail from Kingston, where he was meeting with provincial and territorial environment ministers. Specifically, he said Canadians will not accept the report’s advocacy of emission targets for 2020 that would reduce Canada’s gross domestic product by 3 per cent nationally and 12 per cent in Alberta from business-as-usual estimates.

    Climate change report ‘irresponsible,’ Prentice says – The Globe and Mail.

    Canada cannot take its national unity for granted and must not, in the service of international obligations, allow itself to be immolated by a government policy of such wrenching dislocation.

    Globe and Mail Editorial

    Wow, “irresponsible”, “Threat to Canada’s National Unity?” What could we talking about? Surely, not a report that addresses the cost of meeting Canada’s commitments to greenhouse gas reductions by 2020?. A bit of hyperbole from this nation’s great flagship newspaper and the Environment Minister?

    The study (English summary) looked at two different scenarios, first the weak sauce 20% reduction from 2006 levels by 2020 proposed by the Canadian government. The reason the Canadian government deliberately shifted the baseline from 1990 (the accepted consensus baseline so comparison can be made easily) to 2006 is that if you calculate what the change from 1990 levels is for the Canadian government proposal, it is actually a small increase, not the 20-25% decrease that is needed to put the world on a stabilization path for <2°C rise in temperature. This is unethical and dishonest, like telling the world that the average Canadian is 4 feet tall (head to knee only). The authors of the report know this is an unacceptably weak proposal and therefore looked at what was actually needed, a 20-25% reduction from 1990 levels. BTW, remember that if someone ever shoots a percentage off for you, ask for the baseline, check if this is standard.

    Incidentally, the editorial pages of the G&M has not read its own report, or wilfully ignores all the good news while selectively playing up the bad news, geez, it’s like they have an agenda or something! The good news:

    • Canada CAN meet its climate goals
    • The effect on Canadian GDP growth is modest. Under the required goal of 25% reduction from 1990, GDP growth is about 3% below “business as usual” standards. Note that this year, GDP growth was negative, what percent is that?
    • Alberta, which would “suffer” the greatest reduction from “business as usual” scenarios still leads the country in growth. This is the scenario which the G&M concern trolls as a threat to National Unity
    • Jobs still grow, very few changes from business as usual scenarios
    • Significant Increases in energy costs. But money flows from carbon revenue to defray some of these costs, so actual costs to consumers are modest
    • Massive increases in the efficiency of cars, houses, heating, etc., means lower prices in the long run

    Of course, the environmental, social and geopolitical costs of “doing nothing” are not enumerated. Are we prepared to face a world with melting polar ice caps, climate refugees, water wars and anger? Are we willing to take those Canadian flags off our backpacks and put Swedish flags on them? There is also a very good chance of incremental breakthroughs in electric vehicle technologies squeezing the demand out of oil and completely collapsing Alberta’s economy, making this entire decision moot. Things can change quickly, just ask anyone involved in the BC timber industry! My point is that unless you factor in the costs of doing business as usual, any change proposed will not compare favourably. The report alludes to the cost of doing business as usual, a 5-20% LOSS in global GDP over the century. But does not include this into the calculation of the business as usual scenario. Note that none of the changes envisaged here propose anything but “growth”.

    The changes required are quite significant.

    • Capture and storage of carbon dioxide from the oil and gas industry and power plants (Ha!)
    • Reduction of “fugitive” emissions from the oil and gas industry and from landfills
    • Increased energy efficiency throughout the economy (e.g., in vehicles and buildings)
    • Increased production of renewable energy (e.g., wind power accounts for 18 per cent of electricity generated in 2020 when meeting the 2°C target)
    • Replacement of fossil fuels by cleaner electricity (e.g., for heating buildings).

    When you are near the bottom of the pack when it comes to efficiency and per capita emissions, you do necessarily have to work a little harder. Most of these goals (except the first one which needs a major technological advance) are easily achievable and would put Canada more in line with European countries as far as energy efficiency goes.

    What do the words of the mainstream media and the government mean? We are screwed. Canada has NO leadership or commitment to steer away from the cliff. We do not have a powerful enough constituency for climate change. We have a government and polity completely captured by oil interests. We will be dragged kicking, screaming and unprepared into a new, efficient and carbon constrained world. We may still turn out okay because we are a VERY rich country with very few people. But, be prepared for the backlash.

  • New Source Review stands for now

    Cinergy, now Duke Energy, was trying to claim that as long as its plants’ hourly emission rate did not increase, they could make unlimited “modifications” to the plants. So, in theory, if capacity got doubled so a plant was operating 24 hours a day from 12, the hourly rate would remain the same, but pollution would double. Well,  isn’t that a “new source” then? Apparently, Cinergy did not think so, and after at least 6 years of wrangling, this thing is going to be decided by the Supreme Court this fall. So, once again, the crack team of Roberts, et al. will decide whether we breathe or not, policy by judicial fiat?

    US court hands EPA a win in utility emission case | Reuters.com

    A federal court has ruled that a big U.S. utility must install costly pollution-reduction equipment at its aging coal-powered electric plants if it expands them, handing a victory to the U.S. government in a case that could shape an upcoming Supreme Court ruling.

    The three-member 7th Circuit Court of Appeals in Chicago on Thursday ruled that Cinergy must install emission curbs at its coal-powered plants in the Midwest if it expands them to prolong their operating lives.

    The Environmental Protection Agency had sued the utility to force it to apply for an expansion permit, which would trigger emission-reduction measures.

    In a bevy of cases, U.S. utilities are testing how far they can go to expand aging plants without triggering a section of the Clean Air Act known as “New Source Review.”

  • We're all going to die – Indian Glacier Melting edition

    Big Melt Threatens India’s Water — Bagla 2007 (112): 1 — ScienceNOW

    The massive glaciers of the Himalayas, which hold one of Earth’s largest reserves of snow and ice, have dwindled by one-fifth in the past 4 decades. A team of Indian geologists and remote sensing experts published the alarming news this week–a grim warning that if the trend continues, it could jeopardize the fresh water supply of more than 500 million people in India

    Well, still early news, the worst case scenarios come to pass if there is not enough rain during the monsoon to replenish the glaciers. Here’s a concise Yahoo Answers page compiled by an 18 year old Nicaraguan

    All states will have increased rainfall except Punjab, Rajasthan, Tamil Nadu where it will decrease. Extreme precipitation will increase, particularly along the western coast and west central India.

    Excerpted from the Stern report… My reading of the Stern report leads to the conclusion that global warming will increase water availability in the subcontinent, but also lead to more extreme rainfall and flood events, increased run off, more soil erosion, landslides, etc. Increased glacial melting will add to this mess. So, I don’t really like the conclusion this science article seems to come to. South Asia is not going to run out of fresh water anytime soon, it’s just going to have a hell of a time dealing with it!

  • More Focus on China – Pesticides and Food Safety

    I begin to wonder how much of this was not known previously, and is coming out now, pushed by US domestic food interests who can suddenly become a little more competitive.

    Reuters AlertNet – Pesticides next frontier in China food safety

    China’s farmers overuse pesticides, skip protective clothing and have at their fingertips an array of banned and counterfeit products, raising another area of concern in the country’s fragile food chain. Spraying chemicals on crops improperly or using products that may be fake or banned risks the health of China’s hundreds of millions of farmers and could lead to unsafe levels of residues in fruits and vegetables, experts say. “The government has to stop banned or illegal pesticides being available in the market,” said Angus Lam, a Greenpeace Campaign Manager for Food and Agriculture based in the southern city of Guangzhou. China banned five high toxicity pesticides as of Jan. 1, but Lam said old stock was still in the market, in the hands of traders, retailers and farmers themselves. The government pledged last week to step up inspections in its food industry, saying checks on fertilisers and pesticides would be one of the priority areas.

    China is not alone in this problem. Pesticides get overused in the US as well. But it’s as if all of a sudden, the mainstream press is waking up to the reality that is China. It is a developing country with high levels of growth in manufacturing, and a burgeoning middle class. But government regulation mechanisms have a long way to go to catch up.

    The US surely knows this, and needed to have a more stringent testing regime with food imports from China. But the FDA was not given the mandate or the money. It is very easy to blame the FDA here. The fact of the matter is that any agency is only as good as the money and mandate it’s given. The political will to take a good look at where your food comes from, and how to ensure its safety needs to come first.
