The news is about the only lead smelter in the US, hence the term "plant" was used. It is the Doe Run Co lead smelter in Herculaneum, MO. It is about 70 miles from my house. The mines are operating in the same area.
Don't get your panties wadded up. Only about 5% of the lead produced is used for bullets. Most is for batteries. We've been shipping ore to China for processing for years then they send the clean stuff back. China isn't about to quit doing the dirty work. They don't give two hoots about pollution.
