Gresham, Smith and Partners (GS&P), a leading multi-disciplinary design and consulting firm to the built environment, is pleased to announce completion of Airport Cooperative Research Program (ACRP) Report 99: Guidance for Treatment of Airport Stormwater Containing Deicers. The guidebook, available for download from the Transportation Research Board’s website, offers a process to help airports identify, select, and implement technologies to treat stormwater that has been affected by deicing materials. The guidance also includes suggestions for the design, operation and maintenance of different treatment technologies.
Deicer treatment is often a unique operation for airports and is an operation that can be highly dynamic because of real-time dependencies on weather and airport operations. In an effort to yield a better understanding of deicer treatment technology performance and provide numerous lessons learned regarding applicability, performance, cost, and operational considerations, the research team assessed a variety of airports using differing deicer treatment approaches across the US, Canada and Europe.
“Inadequate management of deicer treatment operations can increase the risk of noncompliance and lead to excessive costs for even the most well-designed treatment system,” commented Tim Arendt, P.E., principal investigator, Gresham, Smith and Partners. “Our in-the-field experiences were melded with theoretical understanding of deicer treatment and consolidated in this guidebook. The information found within this report will provide airport operators with guidance on critical issues to consider during design and operation of treatment systems.”
In addition to the complete Report, 11 fact sheets that address the treatment technologies referenced in ACRP Report 99 are available for download. The fact sheets cover activated sludge; aerated gravel beds; aerated lagoons; anaerobic fluidized bed reactors; distillation; mechanical vapor recompression; moving bed biofilm reactors; passive facultative treatment systems; public wastewater treatment systems; private recycling systems; and reverse osmosis.
The development of Report 99 was led by GS&P with support from Malcolm Pirnie/ARCADIS, Naturally Wallace Consulting, Inland Technologies International, McGuiness Unlimited, Inc. and NewFields. GS&P is an industry leader in development guidance for the aviation industry, including serving as the principal investigatory firm for more than 11 ACRP guidance documents in recent years.
