In yet another milepost in the galactically slow train wreck that is finding a replacement for lead-spiked avgas, the EPA has finally announced its intent to declare leaded fuel environmentally hazardous. And this time, says EPA, we’re serious so all you FAA footdraggers better pay attention. No, really. We mean it. But wait, hold up. What the press release headline said was this, exactly: “EPA to Evaluate Whether Lead Emissions from Piston-Engine Aircraft Endanger Human Health and Welfare.” The waffle word here is “whether.” If the answer is no, no endangerment, then what? Or was this just sloppy prose? Try not to think about it.
