Study in use and management of de/anti-icing constituents with regard to new storm water legislation. Master's thesis
This research identified management practices of airfield and aircraft de/anti-icing constituents which may be implemented to deal with new storm water legislation. Storm water regulations require that deicing operations obtain a NPDES permit for discharges into storm water runoff which may mandate the use of Best Management Practices. An FAA civilian airport survey and a USAF survey were used, with a literature search, to identify practices of de/anti-icing constituents. Four major constituents are used-glycol, urea, calcium magnesium acetate, and sodium formate. Concerns of uncontrolled release of the constituents include high BOD rates, nitrate and nitrite enrichment, impaired aesthetic water quality, ammonia formation from the degradation of urea, and the toxicity of such chemicals to aquatic life. Several options that exist for managing the runoff of de/anti-icing constituents include alternative constituents such as potassium acetate; alternative application procedures such as centralized facilities and greater use of anti-icing operations; collection alternatives using porous surface materials, drainage systems, and holding tanks; and treatment alternatives such as a mobile recovery unit to recycle deicing fluids for re-use....
