Welcome to the discussion of US Politics!
Rules:
- Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.
Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

I have written about it. Didn’t receive a response. I also made public comments of proposed lead regulations in my own industry, pointing out the incongruity of taking little to no federal action on lead paint and avgas. If we have to have a tight timeline to replace millions of lead lines, so should avgas and far fewer aircraft.
Glad you are doing something. Sorry, it just seems you continue to defend using leaded fuel as well as the inaction of the aviation industry through the 80s and 90s even as the dangers of leaded fuel were well understood. The fact that ANYONE is still allowed to use leaded fuel truly boggles my mind.
Well also remember: The aviation sector as a whole has done a LOT to reduce its lead footprint since 1950. Used to be, everything from two seat trainers to transcontinental airliners burned leaded gasoline in reciprocating engines. Now it is fairly rare to find a reciprocating engine of more than 350 horsepower or so in service as they have largely been replaced with turboprops. Sometimes literally replaced; I know of several operations that use older airframes like DeHavilland Beavers/Otters, Grumman Geese/Mallards, or even Douglas DC-3s that have swapped their old radial engines for Pratt & Whitney PT-6s.
Old 80/87 red AVGAS was phased out before I started flying, I've never seen any in person. Granted some aircraft rated for it just started burning 100LL but others started using regular automotive gasoline. 115/145 purple AVGAS was also phased out, though I understand it's made in small batches for certain motorsports events? Even 100/130 green AVGAS is rare to find; 100LL blue AVGAS is meant to do the job of 100/130 with less lead. The industry as a whole has made a lot of broad strokes, now we're working on the details.
Before the 60s, people didn’t consider what tetraethyl lead was doing. It was the groundbreaking work of Clair Cameron Patterson that finally exposed it. Even then industry fought him for years. I would far and away attribute most of those early gains to the wide adoption of faster and higher flying jet aircraft that thankfully do not use leaded fuel. And even turboprops have seen wide adoption, not because of lead fuel, but because they have superior performance and can support higher altitudes.
But, again, I find it unconscionable that in 2024 leaded fuel is still used. Sorry it effects you livelihood (it sure as hell effects mine even though we figured out how to mitigate it 30 years ago and would have stayed that way if it weren’t for some moron tea party Republicans in Michigan that thought they knew more than experts), but our children can’t wait. Hopefully, now nearly 60 years after Dr. Patterson exposed how bad leaded fuel is, leaded gas can finally die.
