(AP) — The 20-year master plan for Omaha’s Eppley Airfield includes eight new gates, major alterations and renovations in the terminal and another parking garage.

The plan approved Tuesday by the airport authority board will be submitted to the Federal Aviation Administration. The projects would be paid for by FAA grants, airport revenue, bonds and new passenger and customer facility charges.

The FAA allows a passenger charge of up to $4.50 each.

Eppley’s director of planning and engineering, David Roth, says the first phase of the plan would begin when the airport hits 4.8 million passengers. He says that could be many years from now. The airport is handling about 4 million passengers a year now.
