Washington, D.C. – Noise levels would be restricted at Jackson Hole Airport under a bill headed to President Bush. The U-S Senate late Friday night agreed to a compromise version of an aviation funding bill already passed by the House. The measure reauthorizes funding for the Federal Aviation Administration and contains an amendment restricting noise levels at the Jackson airport, the only commercial airport in the lower 48 states located in a national park. The amendment was sponsored by Wyoming Senator Craig Thomas, who says the provision will not affect commercial aircraft. Noise at the airport has been rising due to increasing private jet traffic, which includes many older, louder planes. Thomas says less than three percent of the airport's operations are conducted by those older, private jet, but he says those planes have a disproportionately high impact on noise.
