Roberto, I have been out sick and I am now just reviewing the 5-Day Reporting form that was sent to you earlier this
week (attached).
I would like to state something that I would like be on the record and that I wish was included on the "Additional
Comments About the Event" section of the original 5-Day Reporting Form. As you can see from the start of the spill
(11:OOam) an operator was on -site, once the ORC heard from the operator about the spill the ORC came onsite and
stayed onsite until the spill stopped. Since the spill, a certified operator has been onsite 24/7 tending to the plant. We
will continue this 24/7 staffing until we feel comfortable returning back to the approved staffing variance.
The bypass was not caused from the facility being unstaffed and at no time was this bypass taking place without a
certified operator on -site.
We greatly appreciate the staffing variance this facility has been given and we do not take this variance for granted or
lightly.
In Partnership,
