I could be wrong, but the report seems to be that some mines contained asbestos, but that it was manageable, so the only relevant finding was that their end product "sometimes tested positive" for "small amounts" of asbestos during a 30-something-year period. Did the amount/frequency represent a legal responsibility to report it? Did it represent a moral responsibility, based on known science? I haven't seen much about that, and I'd love to hear from some source that at least appears to be attempting objectivity.
