In support of the existing planning process for airport facilities and to protect drinking water sources from runoff containing de-icing chemicals, the following policies apply where the management of runoff that contains chemicals used in the de-icing of aircraft would be a significant threat:

a. relevant airport authorities and operators, in their consideration of future airport facilities, are requested to include appropriate design standards and management practices to prevent the runoff from airport de-icing facilities from becoming a significant drinking water threat.

T-46-S (b): The Source Protection Department of the Halton Region and Hamilton Conservation Authorities shall periodically review the federal regulatory regime and policy to ensure appropriate design standards and management practices are included to prevent the runoff of chemicals at de-icing facilities where this activity is a significant threat. If improvements are warranted, Transport Canada is to be contacted.
