    The deicing and anti-icing of aircraft and airfield surfaces is required by the Federal

    Aviation Administration (FAA) to ensure the safety of passengers; however, when performed

    without discharge controls in place, airport deicing operations can result in environmental

    impacts. In addition to potential aquatic life and human health impacts from the toxicity of

    deicing and anti-icing chemicals, the biodegradation of propylene or ethylene glycol (i.e., the base

    chemical of deicing fluid) in surface waters (i.e., lakes, rivers) can greatly impact water quality,

    including significant reduction in dissolved oxygen (DO) levels. Reduced DO levels can

    ultimately lead to fish kills.

    This Preliminary Data Summary provides information about the air transportation

    industry and the best practices being employed for aircraft and airfield deicing operations, as well

    as for the collection, containment, recovery, and treatment of wastewaters containing deicing

    agents. This study was conducted to meet the obligations of the EPA under Section 304(m) of

    the Clean Water Act, in accordance with the consent decree in Natural Resources Defense

    Council and Public Citizen, Inc. v. Browner (D.D.C. 89-2980, as modified February 4, 1997).

    EPA hopes that this study will serve as an objective source of information that can be used by

    airports, airlines, state and local regulators, and citizen groups.
