ARTICLE: EPA Releases Deicing Regulations
Deicing is an issue at the intersection of aviation safety and legitimate environmental considerations. The FAA’s preferred solution is to spray the aircraft at the last moment before it departs; that is usually a place on the airport for which effluent containment is not easy. The chemicals used for this process are not welcomed in the water and ecosystems.
EPA’s Effluent Limitation Guidelines and New Source Performance Standards for the Airport Deicing Category reflects the thoughtful participation by and comments of A4A, ACI, RAA and AAAE. An unduly harsh set of rule could have been toxic to airport/airline operations. Instead, the new rules require that existing and new primary airports with 1,000 or more annual jet departures (”non-propeller aircraft”) that generate wastewater associated with airfield pavement deicing are to use non-urea-containing deicers, or alternatively, meet a numeric effluent limitation for ammonia.
It’s great to see the aviation/airport industry and EPA work together effectively.
