The recommendations have not solved wildlife management
issues. Waste management areas, for example, are classed as
extremely hazardous and are not recommended within 8 km of the
airport reference point, yet waste storage sites, waste transfer sites
and landfills were all reported within such a radius. Sewage lagoons
are classified as moderately hazardous and yet 52.6% of responding
airports reported one within 8 km of their reference point. Airports
reportingwaste management sites, sewage lagoons and ponds on or
nearby should be addressing their risk and attempting to influence
these land use practices, but only 17.1% of respondents have been
active in land use discussions about nearby landfill practices.
Airports often make poor land use choices. Lands inside and
outside of airports can be leased for agricultural production as
a source of revenue for the airport authority. Respondents noted
agricultural crops airside at 50% of airports, groundside at 39.5%
and within 8 km of the airport reference point at 81.6%. Despite the
possibility of extreme risk, depending upon the specific crop, less
than a quarter of airports have attempted to influence adjacent
agricultural crop management. Because agricultural crops can vary
in the hazards posed to aircraft operations, depending on the type
of crop, agricultural practices implemented, and distance from the
airport, the airport needs to address the specific risks posed by the
agricultural crops present.
