The Air Force (AF) uses many deicing/anti-icing compounds |
|
on its aircraft and airfields. And several new compounds |
|
have been proposed for future use because they are said |
|
to be more environmentally friendly or less corrosive to |
|
aircraft parts and pavements. A comparison of the oxygen |
|
demands of various de-icing and anti-icing compounds is |
|
presented in an effort to determine their relative |
|
environmental impacts. A theoretical approach and various |
|
manufacturers' data were used to place the compounds on |
|
an even footing. For valid comparisons, the AF must |
|
request that BOD/COD tests be run on all compounds at |
|
equivalent concentrations using the same units. Then this |
|
data, along with application rates for the same |
|
temperature range, can be used to make comparisons on |
|
which deicing compounds have the least environmental |
|
impact. The EPA suggests that COD, rather than BOD, is |
|
the best test for deicing compounds because it captures |
|
total oxygen demand, is not affected by additives, is |
|
simple to conduct, can be measured in real time, and is |
|
not temperature dependent. Other environmental aspects of |
|
aircraft and airfield deicing, such as storm water and |
|
wastewater permitting requirements affecting deicing |
|
activities, are discussed. A partial summary of the 2008 |
|
Air Force survey of deicing practices at its |
|
installations for deicing seasons 2005 through 2008 is |
|
provided. The survey shows the number of aircraft deiced |
|
versus the number of sorties flown during a deicing |
|
season. The amounts of aircraft and airfield deicing |
|
compounds used by the AF are compared to those used at |
|
commercial airports. The AF deicing footprint on the |
|
environment is much lower than that of commercial |
|
airports. |
