The facility at Doe Run that closed only processed mined lead ore, or primary lead.
95% of the lead used in the United States comes from recycling old products that contain lead, such as batteries and the like, not from primary lead such as that produced at the Doe Run facility.
That facility closing will not affect the availability of lead in the US.
Stop fear mongering and rumor spreading.
Sierra is only 3 hours distance from Doe Run, and they say it wont affect them at all.
