In April the Environmental Protection Agency issued an Advance Notice of Proposed Rulemaking on Lead Emissions from Piston-Engine Aircraft Using Leaded Aviation Gasoline - a move sure to contribute to the effort on how to kill general aviation.
As I read through this Notice of Proposed Rulemaking it is clear that this document lacks any real data that ties the emissions generated by piston powered aircraft to any specific harm or injury to the population in general, but rather uses what I consider scare tactics. For example, here is an excerpt of part of this Notice: "Lead Concentrations and Exposure to Lead from Piston-Engine Aircraft

- * Lead concentrations in air increase with proximity to airports where piston-engine aircraft operate.
- * Lead emitted in-flight is expected to disperse widely in the environment because lead is emitted as a small particle and can travel widely before depositing to soil, water, vegetation or other surfaces.
- * Approximately 16 million people live within one kilometer of the approximately 20,000 airport facilities in the U.S.
- * Over 3 million children attend school within one kilometer of the approximately 20,000 airport facilities. "
