The Ada County,Idaho, commission is reconsidering Allied Wastes plan to open a 560-acre landfill, according to a report in the Idaho Statesman. The commission, which initially denied the waste companys application on a technicality, heard testimony on June 14 from a dozen people all opposed to the landfill. Representatives from two federal agencies said that building a landfill near the Boise airport will increase the risk of bird and airplane collisions. Bird strikes cause $450 million in aircraft damage annually, said Shane Koyle, a wildlife biologist with the U.S. Department of Agriculture, in the report. The commission voted to close the public record and continue discussion on June 28.
