The Federal Aviation Administration will do an aeronautic study after a south-central Idaho company increased the size of exhaust stacks. Pilots from a nearby airport cited safety concerns.
Steve Engebrecht of the FAA tells The Times-News in a story on Wednesday that the study will take about 45 days to complete.
Burley Airport Users Association President Jack Hunsaker says the new stacks put in by Gem State Processing could interfere with some approaches and departures.
Gem State Processing General Manager Bill Schow says the company replaced temporary stacks with permanent exhaust stacks that are up to 10 feet taller and have larger diameters.
Burley City Administrator Mark Mitton says Gem State didn't tell city officials or Minidoka County about making the stacks bigger.
