On Thursday, August 29, the California legislature officially signed a ban on leaded aviation gasoline, according to AvWeb. This law that enforces the ban is now on its way to the Governor of California, Gavin Newsome. Once he signs off on the bill, which he is predicted to do, the ban would go into effect throughout the state beginning in 2031. California would be the first state to ban leaded aviation fuel if Newsome signs the bill. Thumbnail Image: InsectWorld | Shutterstock
