Not sure why the EPA and FBI decided to get involved.
Because OSHA can’t ban the use of lead in bullets and neither OSHA nor the EPA can come in with an armed attack.
Ok, now that I think about it they might be able to now; but they need some on the job training since they didn’t used to be able to.
Forgot about the Hope and Change.
But USA Brass doesn't deal in bullets, they deal in fired brass.
Sure there is probably some lead traces, although not much since most bullets are jacketed and the lead doesn't touch the brass of the cartridge case (the brass) There is also lead in the primers, but again, not much in fired primer.
The employees are more likely to have gotten a little extra lead exposure at the local gun ranges. Or from any number of other sources.
