While leaded fuel has been banned in almost all other transportation applications, it is still being used by piston engine aircraft. For over two decades, there have been efforts to find a replacement for leaded avgas. While a replacement has not yet been fully developed or vetted, it is believed that there will likely be fueling infrastructure and other airport challenges before any replacement can be fully implemented. Addressing these challenges will take many years to ensure that the industry is able to safely transition. There may be practices that airports can adopt to reduce baseline lead emissions and/or exposure and may be able to mitigate, if not reduce, lead emission impacts. For example, one mitigation strategy may be to move the run-up area. But, airports need to understand all considerations of the mitigation strategies.
The objective of this research was to develop guidelines for airports on minimizing lead emission impacts.
