Environmental Hogwash

Chicken has taken on a whole new meaning for Faye Lear, of White Plains, in western Kentucky, who lives 300 feet from two giant barns containing thousands of birds laying eggs for Tyson Foods.

There are the sickening wafts of ammonia and bird feather dust that chase her inside from her front porch. Clouds of well-fed flies swarm her car windows. Once a year, when the barns are emptied for cleaning, mass infestations of mice overrun the neighborhood.

"It's like an open sewer for a big city," says Lear, who works as a nurse. "It's nauseating, it burns your eyes. I wouldn't call them a farm – they're like an industry."

Across the country, thousands of these "factory farms" – each warehousing thousands of tightly confined hogs, chickens or cows – produce potentially toxic air emissions. These fumes are the byproduct of 1.3 billion tons of waste created annually by the sprawling compounds, which are the top polluters of America's waterways according to the Environmental Protection Agency.

Despite this torrent of manure, and a growing number of lawsuits by sickened neighbors, "there are essentially no pollution controls on these operations whatsoever," says Sierra Club attorney Barclay Rogers. "The environment is being wrecked by these operations."

But the EPA isn't ready to stanch this stench anytime soon. According to documents obtained by the Sierra Club through a Freedom of Information Act request, the EPA has developed a voluntary air monitoring program in close collaboration with animal-industry groups such as the National Pork Producers Council (NPPC) and the US Poultry and Egg Association. (The cattle industry chose not to participate.)

The plan, still being hashed out internally at the agency "resolves [participating companies'] civil liability for potential violations" of federal clean air laws. In effect, this would mean a two-year amnesty from enforcement of the Clean Air Act – as well as immunity from federal Superfund and environmental right-to-know laws. During this time, some of the nation's largest pig and chicken facilities would gather air emissions data. Only later could they be penalized for exceeding the emmissions limits for ammonia and hydrogen sulfide.

Environmentalists are up in arms. "The exchange of data for prosecutorial immunity is antithetical to the notion of aggressive environmental enforcement," says Rogers.

"These [poultry] operations are generating extraordinary quantities of ammonia gas," says Rogers. Ammonia gas is listed as an "Extremely Hazardous Substance" in the Superfund law and is a key contributor to particulate matter pollutants. Indeed, EPA researchers have found that "animal husbandry operations" are responsible for 73 percent of all ammonia released into the air nationwide.

In 2001, EPA inspectors detected disturbingly high releases of ammonia from Buckeye Egg Farm in Ohio, then the nation's fourth-largest egg producer. Some Buckeye facilities were churning out 700-800 tons of particulate matter per year – far in excess of the federal air-quality reporting standard of 250 tons. After years of enforcement battles begun under the Clinton administration, the EPA this past February secured a Clean Air Act settlement and a $880,598 civil penalty against the now-defunct Buckeye.

A 1999 analysis of air data by the Environmental Defense Fund found that hog operations spew 167 million pounds of ammonia nitrogen into the atmosphere each year in North Carolina alone. "Studies in the North Carolina region where hog facilities are clustered show that the level of ammonia in rain has doubled in the past decade," the report stated.

Epidemiological studies, meanwhile, suggest the fumes may cause increased rates of asthma, chronic bronchitis and other respiratory disorders. A 1999 report prepared by epidemiologist Steve Wing for the North Carolina Department of Health and Human Services found that people residing near a large hog facility suffered increased levels of nausea, diarrhea and respiratory problems.
