FRANKFORT, Ky. - The Sierra Club has filed a lawsuit against poultry giant Tyson Foods for allegedly failing to clean up waste from four Kentucky chicken farms.<br>
<br>
The lawsuit, mailed to court officials Monday by the environmental group, includes charges that Tyson failed to report releases of ammonia.<br>
<br>
The federal Superfund law requires a permit if an operation releases more than 100 pounds of ammonia per day.<br>
<br>
Tyson is among poultry companies that have contracts with farmers to grow chickens, typically in large, barnlike structures called chicken houses.<br>
<br>
"Tyson Foods and the farmers who grow chickens for us are dedicated to adhering to the laws of the land and being good stewards of the environment," the Springdale, Ark.-based company said in a statement Monday.<br>
<br>
Tyson operations in three western Kentucky counties are at issue in the suit. Local residents have also filed complaints in court against Tyson and the chicken farms over the smell.<br>
