Perchlorate Coverup?

Byoliveridley

Pentagon pressured EPA on perchlorate

The federal government has been inconsistent and at times intentionally silent on how much perchlorate is safe in drinking water. As a result, environmental groups contend, defense contractors and the government have been indefinitely shielded from cleanup costs while infants and pregnant women are exposed to a chemical that impairs thyroid function and can slow infant brain development.

Perchlorate is the oxidizing component of rocket fuel that has been proven to interfere with thyroid function at low levels. The defense department is probably the single largest source of localized contamination. So, expecting the EPA (politically appointed head) to regulate the defense department (politically appointed head) is a little naive.

Industry advocates argue that the science on perchlorate is not precise enough to warrant strong — and extremely costly — remedies.

Ah, where would we be without the plutocracy-protectionary principle!

  • Bill to exempt factory farms from pollution laws

    pigSmell manure?

    FEED – May 2006

    Congress may exempt factory farms from pollution laws Large agribusiness companies are pushing their friends in Congress to exempt factory farms from the pollution reporting and cleanup provisions in key pollution laws. The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, also known as Superfund) and the Emergency Planning and Community Right to Know Act (EPCRA) provide an essential safety net for protecting water supplies from livestock pollution and for providing warnings of toxic air emissions from factory farms. Over 140 representatives are supporting a bill, H.R. 4341, that would give this sweetheart deal to factory farms. The bill may soon be attached to a “must-pass” spending bill in an effort to speed this ill-conceived measure through Congress. Please call your representative and urge him or her to oppose this dangerous legislation. To learn more, read the Sierra Club’s fact sheet (pdf) on this issue.

    Factory farms tend to be located in rural areas next to communities that do not have the power to stop them/mobilize against them. This provision will further stack the deck against these communities. Anyone who thinks manure, pesticide runoff, ammonia, etc are not hazardous to the ecosystem and to human health needs to live next to one of these “farms”. I am hazarding a really wild guess that Congressman Hall (the sponsor) does not have to deal with issues such as these.

    Ethanol significantly worse than gasoline for air pollution

    Byoliveridley

    So, Mark Jacobson from Stanford, an accomplished atmospheric chemist and modeler from Stanford, puts ethanol into his modeling mix as an automobile fuel and comes up with increased ozone, peroxyacetyl nitrate (PAN, an ozone precursor) and acetaldehyde, leading to a possible increase in mortality. Without reading his paper, I cannot comment on the assumptions used, but this is an additional issue to be concerned about as our politicians continue to binge on alcohol. It’s weird, almost as if there’s something intoxicating and addictive about this fuel :-;

    Effects of Ethanol E85 versus Gasoline Vehicles on Cancer and Mortality in the United States

    Ethanol use in vehicle fuel is increasing worldwide, but the potential cancer risk and ozone-related health consequences of a large-scale conversion from gasoline to ethanol have not been examined. Here, a nested global-through-urban air pollution/weather forecast model is combined with high-resolution future emission inventories, population data, and health effects data to examine the effect of converting from gasoline to E85 on cancer, mortality, and hospitalization in the United States as a whole and Los Angeles in particular. Under the base-case emission scenario derived, which accounted for projected improvements in gasoline and E85 vehicle emission controls, it was found that E85 (85% ethanol fuel, 15% gasoline) may increase ozone-related mortality, hospitalization, and asthma by about 9% in Los Angeles and 4% in the United States as a whole relative to 100% gasoline. Ozone increases in Los Angeles and the northeast were partially offset by decreases in the southeast. E85 also increased peroxyacetyl nitrate (PAN) in the U.S. but was estimated to cause little change in cancer risk. Due to its ozone effects, future E85 may be a greater overall public health risk than gasoline. However, because of the uncertainty in future emission regulations, it can be concluded with confidence only that E85 is unlikely to improve air quality over future gasoline vehicles. Unburned ethanol emissions from E85 may result in a global-scale source of acetaldehyde larger than that of direct emissions.

  • Solar plant cheaper than conventional plants

    Byoliveridley

    Generating clean electricity that's as cheap as power from fossil fuels is the Holy Grail of green-energy companies. A new solar project powering California homes appears to be closing in on that prize.

    Sempra Generation, a subsidiary of Sempra Energy in San Diego, just took the wraps off a 10-megawatt solar farm in Nevada. That's small by industry standards, enough to light just 6,400 homes. But the ramifications are potentially huge.

    A veteran analyst has calculated that the facility can produce power at a cost of 7.5 cents a kilowatt-hour, less than the 9-cent benchmark for conventional electricity.If that’s so, it marks a milestone that renewable fans have longed for: “grid parity,” in which electricity from the sun, wind or other green sources can meet or beat the price performance of such carbon-based fuels as coal and natural gas.

    via Los Angeles Times: Sempra solar energy project makes advances in costs.

    This is great as long as the math is real. The company has made quite a few changes from conventional solar, including using cadmium telluride as the semiconductor instead of the more expensive polycrystalline silicon and fashioning them into thinner films.

    I am not a big fan of unverified claims, especially when so much money is likely to be involved. But the exact number is not important. This installation appears to get close to or greater than grid parity without the externalities of fossil fuel power generation (carbon costs, mercury mitigation, etc.) being accounted for on the “conventional” side.

    The future appears to be sunny!

    One small, niggling issue, can we stop calling coal “conventional”? Coal comes from the remains of prehistoric plants that made all their biomass by using the sun as a fuel source, got buried way underground, and, after millions of years at high pressure and no oxygen, formed a carbon rich material that if burned, releases a small fraction of the energy that the sun put in it! As such, using the sun directly as a power source is about as conventional as it gets, everything else is 2nd order, derivative and fairly inefficient.

    Environmental Racism, Global Warming Edition

    Byoliveridley

    As armchair critics debate endlessly on the virtues and vices of carbon trading versus carbon taxes, they are in no danger of losing their armchairs (or their homes, or their money, or their livelihood). Africa and Asia, not so lucky.

    Poor Nations to Bear Brunt as World Warms – New York Times

    Two-thirds of the atmospheric buildup of carbon dioxide, a heat-trapping greenhouse gas that can persist in the air for centuries, has come in nearly equal proportions from the United States and Western European countries. Those and other wealthy nations are investing in windmill-powered plants that turn seawater to drinking water, in flood barriers and floatable homes, and in grains and soybeans genetically altered to flourish even in a drought. In contrast, Africa accounts for less than 3 percent of the global emissions of carbon dioxide from fuel burning since 1900, yet its 840 million people face some of the biggest risks from drought and disrupted water supplies, according to new scientific assessments. As the oceans swell with water from melting ice sheets, it is the crowded river deltas in southern Asia and Egypt, along with small island nations, that are most at risk.

    I read another story about Bangladesh recently, apparently in Bangladesh, there will be both flooding and drought due to cimate change!

    We are fighting climate change on the front line,” Professor Nishat
    told The Independent earlier this year. “But the battle has to be
    integrated across all countries.”

    Bangladesh has good reason to feel aggrieved at global warming. Its
    annual carbon emissions only 0.172 tons per capita, compared to 21 tons
    in the US.

    If the rivers dry up, it would leave Bangladesh completely at the mercy of the rains.

    What is to be done? There are no simple answers, but this is a global issue that requires a global solution. There needs to be a relentless push for efficiency and conservation, with technologies being made available sans intellectual property and patent protection to help India and China control emissions. Efficiency is where the low hanging fruit are. This wikipedia article is a decent compendium of options.

    Europe has started on the control path already. The U.S has to act, will it do anything this year? Or do we have to wait for this? I am very cynical about the West’s ability and willingness to act in this regard. When the prime contributors and benefiters of a harmful action are not the same as the ones who will face the worst consequences, where’s the will? As life in the third world becomes more miserable, the rich countries can always build more walls.

    No fun and games here!

  • Powerful Story of Environmental Racism

    I have nothing to say, just read and weep.

    A Well of Pain – washingtonpost.com

    She has had cervical polyps. Another of her daughters, Holt-Orsted’s sister, has had colon polyps. Three of Holt-Orsted’s cousins have had cancer. Her aunt next door has had cancer. Her aunt across the street has had chemotherapy for a bone disease. Her uncle died of Hodgkin’s disease. Her daughter, 12-year-old Jasmine, has a speech defect.

    They believe trichloroethylene, or TCE, is to blame for it all. The carcinogen leaked from the county landfill, just 500 feet away, and contaminated the Holts’ well water. That fact is undisputed. For years, the family drank that water, bathed in that water, cooked in that water — and had no clue that it might harm them.

    More…

    In that box, she found letters and documents indicating that Tennessee environmental and water officials had concerns about the possibility of TCE appearing in the Holt’s well water as early as 1988. The Holts’ well was left untested for nine years while TCE problems in the wells of white families were tended to with haste, the records showed.

    Even more…

    Meanwhile, the toxin also showed up at high levels in a spring and several wells in 1993 and 1994. The white families at those sites were immediately told to stop using the water. And tests were conducted repeatedly all around the landfill — but not at the Holt well.

  • GE – weakening air pollution standards

    GE – we bring good things to life (and kill them with Diesel exhaust).

    Clean Air Watch – Blog for Clean Air

    General Electric Co., which is running a marketing campaign promoting itself as environmentally friendly, has pushed to weaken smog controls for railroad locomotives in rules about to be proposed by the Environmental Protection Agency.

    The rules, which could take effect between 2011 and 2017, are designed to cut smog and soot levels and would replace standards adopted in 1997. Since the rules would apply to new locomotives and could require changes on older ones, they would have a big effect on GE, which dominates the nearly $2 billion-a-year North American locomotive market. While the nation’s other locomotive maker and diesel-engine makers say they are prepared to meet the proposed new standard, GE argues it is “unlikely to be achieved” and has proposed a weaker one.

    I have nothing to say, just another example of the plutocracy-protectionary principle, nothing new, same old Modus Operandi.
