To follow up on our conversation about Wire -Bond, we've conducted in-house monitoring at the facility on 10/15/2012,
6/13/2013, and 2/15/2017. 1 was a bit high in my estimates on the phone, but the highest zinc concentration we've
found was 130 mg/L in 2012. We also found values of 86 mg/L in 2012 and 9 mg/L in 2017. There have been other
exceedances, but zinc is the primary issue. I don't have my field notes in front of me, but from what I recall they are
regularly finding zinc of 5 to 7 mg/L during their self -monitoring.
