It wasn't the mine, it was the smelter. You even later say that our mined ore would be processed elsewhere and returned.
This has been a story for a time, and all the bullet manufactures have said they are getting their lead from recycled sources, not from freshly smelted ore.
Granted, there will now be more competition for the recycled sources.
Aviation gas unaffordable? How many plane owners are living paycheck to paycheck? 2g per gallon is going to make a difference in affordability? Gas has already tripled in price without worrying about 2g of lead in every gallon affecting that price. I don't see that having a significant impact, much less making it "unaffordable."
But yes, I'm on your side here. The EPA is out of control. We can cut back on emissions without strangling our producers in the process.
