Airport Deicing Effluent Guidelines
The Federal Aviation Administration (FAA) requires airlines and airports that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement. This ensures the safety of passengers and cargo operations. However, when performed without discharge controls in place, these deicing operations can degrade nearby water bodies.
Airports are required to obtain stormwater discharge permits under the NPDES program and ensure that wastes from deicing operations are properly collected and treated.
The Effluent Guidelines require existing and new primary airportsPrimary airportA primary airport is a commercial service airport with more than 10,000 passenger boardings each year (49 U.S.C. 47102). with 1,000 or more annual jet departures that discharge wastewater associated with airfield pavement deicing to use non-urea-containing deicers, or alternatively, meet a numeric effluent limitation for ammonia.
New airports with 10,000 annual departures located in certain cold climate zones are required to collect 60 percent of aircraft deicing fluid after deicing. Airports that discharge the collected aircraft deicing fluid directly to waters of the U.S. must also meet numeric discharge requirements for chemical oxygen demand.
The Effluent Guidelines do not establish requirements for aircraft deicing discharges at existing airports. Such requirements will continue to be established in general permitsgeneral permitAn NPDES general permit is written to cover multiple dischargers with similar operations and types of discharges., or for individual permits on a site-specific basis.
