For years, residents here complained about the yellow smoke pouring from the tall chimneys of the nearby coal-fired power plant, which left a film on their cars and pebbles of coal waste in their yards. Five states — including New York and New Jersey — sued the plant’s owner, Allegheny Energy, claiming the air pollution was causing respiratory diseases and acid rain.
So three years ago, when Allegheny Energy decided to install scrubbers to clean the plant’s air emissions, environmentalists were overjoyed. The technology would spray water and chemicals through the plant’s chimneys, trapping more than 150,000 tons of pollutants each year before they escaped into the sky.
But the cleaner air has come at a cost. Each day since the equipment was switched on in June, the company has dumped tens of thousands of gallons of wastewater containing chemicals from the scrubbing process into the Monongahela River, which provides drinking water to 350,000 people and flows into Pittsburgh, 40 miles to the north.
Even as a growing number of coal-burning power plants around the nation have moved to reduce their air emissions, many of them are creating another problem: water pollution. Power plants are the nation’s biggest producer of toxic waste, surpassing industries like plastic and paint manufacturing and chemical plants, according to a New York Times analysis of Environmental Protection Agency data.
Much power plant waste once went into the sky, but because of toughened air pollution laws, it now often goes into lakes and rivers, or into landfills that have leaked into nearby groundwater, say regulators and environmentalists. The Environmental Protection Agency projects that by next year, roughly 50 percent of coal-generated electricity in the United States will come from plants that use scrubbers or similar technologies, creating vast new sources of wastewater.
Yet no federal regulations specifically govern the disposal of power plant discharges into waterways or landfills. Some regulators have used laws like the Clean Water Act to combat such pollution. But those laws can prove inadequate, say regulators, because they do not mandate limits on the most dangerous chemicals in power plant waste, like arsenic and lead.
For instance, only one in 43 power plants and other electric utilities across the nation must limit how much barium they dump into nearby waterways, according to a Times analysis of E.P.A. records. Barium, which is commonly found in power plant waste and scrubber wastewater, has been linked to heart problems and diseases in other organs.
Ninety percent of 313 coal-fired power plants that have violated the Clean Water Act since 2004 were not fined or otherwise sanctioned by federal or state regulators, according to a Times analysis of Environmental Protection Agency records. Hatfield’s Ferry has violated the Clean Water Act 33 times since 2006. For those violations, the company paid less than $26,000. During that same period, the plant’s parent company earned $1.1 billion.
Last year, when Hatfield’s Ferry asked the state for permission to dump scrubber wastewater into the Monongahela River, the Pennsylvania Department of Environmental Protection approved the request with proposed limits on some chemicals.
But state officials placed no limits on water discharges of arsenic, aluminum, boron, chromium, manganese, nickel or other chemicals that have been linked to health risks, all of which have been detected in the plant’s wastewater samples, according to state documents.
wastewater often contains high concentrations of dissolved arsenic, barium, boron, iron, manganese, cadmium, magnesium and other heavy metals that have been shown to contribute to cancer, organ failures and other diseases. Company officials say the emissions by the plant will not pose health risks, because they will be diluted in the river. [what a shame]
A 2007 report published by the E.P.A. suggested that people living near some power plant landfills faced a cancer risk 2,000 times higher than federal health standards.
In 2000, Environmental Protection Agency officials tried to issue stricter controls on power plant waste. But a lobbying campaign by the coal and power industries, as well as public officials in 13 states, blocked the effort. In 2008 alone, according to campaign finance reports, power companies donated $20 million to the political campaigns of federal lawmakers, almost evenly divided between Democrats and Republicans.
“Americans want cheap electricity, but those of us who live around power plants are the ones who have to pay for it,” Mr.Philip Coleman, who lives about 15 miles from Hatfield’s Ferry said. “It’s like being in the third world.”
