Santa Clara County officials and advocates are rejoicing as the federal government agrees to reassess the use of leaded aviation gasoline nationwide.
During a news conference Wednesday, County Counsel James Williams announced the Environmental Protection Agency approved a petition from the county and several environmental organizations to evaluate whether leaded fuel used by airplanes is a threat to public health and welfare. Leaded fuel for cars was banned in the U.S. more than two decades ago, but it is still used by some airplanes, including those at the Reid-Hillview and San Martin airports in Santa Clara County.
"Today is a landmark milestone in the long effort to ban leaded aviation fuel," Williams said.
The EPA will issue an "endangerment finding" later this year for public review, and then make a final finding in 2023. This finding would potentially allow the EPA to take action under the Clean Air Act to curb the use of leaded aviation fuel.

Red, do you have the aviation list?
YES, DO YOU NEED A COPY?
Aviation Ping!.................
Meybee if de planes fly on unleaded den dere won’t be no more chemtrails ....
thanks.
Good thing they don’t use coal for those planes.
Santa Clara County has been trying to kill RHV for the last 4 decades because they want to develop it into high rise housing for the citizens of Mexico.
That is absolutely true, IMO.
I’m wondering if there is an established workaround for this. Lead was an anti-knock additive that allows for higher compression engines. A lot of civil aviation aircraft were built decades ago. If they dropped the lead content those engines would have to be de-tuned.
Well, there goes 100LL AvGas for all of those 1970s era Cessnas.
Some can be converted to use unleaded 91 octane automobile gasoline (AutoGas,) but not all.
program note: when the EPA (End Progress Altogether) forced ultra low sulfur on kerosene for heating, it disabled most kerosene space heaters across the country.
This was because part of the mix was biodiesel.
I know this because I used to spot heat my house with a kerosene space heater.
It was great in the winter time, because I could get my living space heat bubble up to 75 degrees for pennies, as opposed to the then-expensive natural gas heating that was my main heating fuel.
I would start the space heater outside, let it get up to temp, then bring it inside.
No fumes for a well-adjusted heater.
I would bring it outside to put it out, once again avoiding the fumes.
One year, I suddenly started having trouble with the heater.
I realized later that it was the switch to ultra-low sulfur kerosene. After that year, it was no longer economical to use kerosene - the price per gallon tripled, and and I was having to change wicks within weeks - whereas before, the wicks would last half a season.
Thanks, Blowbama!
Can you add me to the ping list? Thanks...
Don’t the still sell leaded fuel additive?
Lead in fuel serves a need that some engines require. I am not sure about aircraft engines, but if you drive a pre mid 70’s engine. You NEED lead, if not, you have to put IN lead additives.
The valve seats will breakdown. Newer engines have hardened valve seats.
I send family members in Calif. lead additive for a few cars from the 50’s.
I think so........................
Added..................
Swift Fuels has certification for “over 1800 models of GA aircraft” for UL94 but there are still major questions on it.
Haven’t kept up on this little controversy but aviation is full of debacles where a change like this wasn’t supposed to cause problems...but did.
Don’t even mention low sulfur diesel. Talk to all the diesel owners with CP4 Bosch fuel pumps.
Germany uses higher sulfur which provides lubrication that American low sulfur does not.
Almost a $10,000 repair caused by wrong fuel
There are about 200,000 General Aviation aircraft in America. Factor out turboprops and you are probably around 130k.
That’s around 26k per state. A shocking number of those never leave the ground. The ones that do fly a shockingly low number of hours each year.
They are creating a horrific expense and a level of danger to stop a handful of engines. General aviation emissions cannot be one ten thousandth of what cars put out.
This is just screwing with people. And if they remove it, there will instantly be a market for additives and people will add it right back in.
