In October 2019, Pittsburgh International announced it will become the first major U.S. airport powered entirely by a microgrid. The microgrid is unique because not only will it power both terminals, the airfield, the Hyatt hotel and a Sunoco gas station, it will be fueled in part by the airport’s own natural gas wells drilled on-site and nearly 8,000 solar panels across eight acres.

In accordance with the National Environmental Policy Act (NEPA) of 1969 and FAA Order 5050.4B, Implementing Instructions for Airport Actions, the Allegheny County Airport Authority (ACAA) is publishing a notice of availability (NOA) of the FONSI and Final Supplemental EA for the PV Solar Array Microgrid Phase 2 Expansion Project.

Community Support

Members of the Airport Authority team participate in community service activities throughout the year, including:


From saving plastic water bottles to spent aircraft deicing fluid, Pittsburgh International Airport has implemented several programs to help reduce waste in its daily operations.

  • Water bottle filling stations can be found in several locations through PIT’s Airside and Landside Terminals. Since beginning the program, the airport has saved an average of 340,740 water bottles per year.
  • To promote waste reduction, Pittsburgh International also offers Beverage Disposal Stations near its security checkpoints. The stations allow passengers to dump their unfinished drinks prior to the screening process and then keep or recycle their bottle or cup. Learn more here.
  • Pittsburgh International was one of the first airports to begin managing and reclaiming spent aircraft deicing fluid. The airport has captured and recycled more than 150 million gallons since 1998. Learn more here.

Food Rescue

In partnering with one of the fastest-growing food recovery organizations in the U.S., Pittsburgh-based 412 Food Rescue, the airport provided nearly 4,000 meals for the Pittsburgh community in 2018 and rescued more than 4,300 lbs. of food. The partnership includes twice-weekly pickups of excess food from more than 30 restaurants throughout the airport. Learn more about the partnership here.


Pittsburgh International Airport’s wildlife population includes millions of honeybees, thanks to a thriving apiary program held on airport property. With large amounts of unused land, airports including PIT, are excellent sanctuaries for the declining honeybee population, which has been threatened by stresses including exposure to pesticides, parasites and poor nutrition.
