A study ordered by Congress says the burning of fossil fuels costs the U.S. $120 billion annually and declares coal the biggest single source of such external expenses. But the damages are likely to be even higher.
The study conducted by the National Academy of Sciences set out to measure the costs not incorporated into the market price of a kilowatt-hour or a gallon of gasoline or diesel. The main budget item: excess mortality. According to the authors, 20,000 people die prematurely every year due to health complications brought on by criteria air pollutants that are released in the process of burning fossil fuels. These toxins include soot particles, which cause lung cancer; nitrogen oxides, which contribute to smog; and sulfur dioxide, the main culprit behind acid rain. While these hidden public health costs are caused almost equally by coal and oil, their single biggest source is coal burning, according to the study.
The findings add support to the efforts of regulators and environmentalists who are pushing for stricter regulations of power plant emissions at a time when representatives of the Obama administration and the E.P.A. are debating how to move forward on the issues. However, critics of the status quo say that the estimates that were not incorporated in the study are even more noteworthy than the enormous price tag researcher from the National Academy of Sciences put on the hidden costs of fossil fuels. These include, aside from the environmental damage of global warming or the damages from burning oil for trains, ships, and planes, the damages from current solid waste management practices in the power industry.
Evidence shows that there has been a dramatic increase in coal waste products that are discarded in waterways or stored in ways that endanger human health. In many cases, such disposal or storage is not regulated or existing regulations are not enforced. Consequently, the hidden cost of power production from coal is likely to be significantly higher than the NAS estimate, critics argue. And thus far it is unclear when the Obama administration will push for additional regulation to curb the increase in harmful pollution.
The production of coal waste such as fly ash and other toxic byproducts of generating electricity from coal, in particular, has increased over the past two decades. To some extend this is the result of an increasing demand for electricity in the U.S. However, improvements in air pollution controls have contributed to this trend even more. Contaminants and waste products that used spew through the power plants’ smokestacks are now captured with greater frequency in solid form. As a result, American coal fired power plants produced 45 percent more combustion waste last year than in 1990, some 130 million tons in total. That’s enough to fill a train of box cars stretching from the District of Columbia to Australia.
While some of this waste product is used for construction fill and other “beneficial uses”, the majority is deposited in 1300 storage sites across the country, most of them unregulated and unmonitored. These dumps, which hold huge piles of this solid waste in 46 states, can reach up to 1500 acres. Frequently, they contain heavy metals such as arsenic, lead, mercury and selenium, all of which the EPA considers a threat to water supply and human health. Different studies have shown that substances leaching from storage sites can cause cancer and birth defects, according to the New York Times.
Yet currently these disposal sites are not subject to federal regulation. Tyson Slocum, an expert in environmental regulation and energy policy with the consumer rights organization Public Citizen in Washington whom I spoke with a few weeks ago, says, “The way we deal with coal combustion products is a big loophole in the country’s waste management system.” He explains that in the absence of federal policy, the states have set requirements, which vary significantly. Alabama, for example, does not regulate the waste product at all, except through nationally mandated water discharge permits. In Texas no groundwater monitoring or engineering requirements exist for utilities that dump coal ash on site.
According to Slocum, these differences in regulation are as much as the result of the varying regional influence of the coal industry as they are the product of tight state budgets. “Many states simply do not have the financial resources to pay the personnel costs necessary to regulate and monitor these waste sites.”
