The BMP action levels established in accordance with permit requirements and in effect for 2016
are as follows:

on the dates outlined in the following table. A brief summary of information for these dates are
included as required by permit Condition A.(6.), Section EA The permit -required BMP
investigation reports are maintained at the mill. None of the BMP action level days resulted in
disruption to the wastewater treatment plant. The Canton Mill met all NPDES annual average
effluent limits for the period July 1, 2015 to June 30, 2016.

Cause and Corrective Action s — Non-BMP event. During
the period of 6/16 & 6/17 the purge stream from the CRP
process was increased from 5 gpm to 13 gpm. This was an
effort to reduce the amount of chlorides in the black liquor
system. Although these efforts proved beneficial to the
Recovery process black liquor cycle it also increased the
amount of color coming into the WWTP. The purge rate
was cut back to 8 gpm on the morning of 6/18. Subsequent
influent color monitoring showed a reduction in color after
the adjustment was made.

action
Cause and Corrective Action s — BMP event. A leak
developed in the piping leading to the East Unoxidized
Black Liquor Tank. The material lost from the piping was
being collected and put back into the process through the
#11 Recovery sump. Although a majority of this material
was captured, a small portion did reach the WWTP influent.
As a mitigation measure, prior to piping repair, two bark
dams were constructed to prevent any further material from
reaching other sewers that do not lead to sumps.
Another leak was observed on the dome sidewall on the 1st
effect of the Swenson evaporators. Mitigation measures
were also implemented to prevent excess material from
entering the sewer. Sandbags were placed to collect the
material which was then pumped with an air pump to the
nearby sump so that the material could be put back into the
process.
Other items of note were that the #11 & #15 digesters were
taken out of service to repair heater tube leaks. These
leaks, although not significant, did contribute to the
incoming color loading to the WWTP. Once repaired these
digesters were put back into service and monitored.

Recovery personnel began to mitigate the source by

stacking sandbags to contain the loss and divert the flow of
62,431 Ibs/day
material to a nearby air pump for pick up. Any additional
78,058 Ibs/day
loss of colored material was captured in the area sump and
put back into the liquor cycle for processing.
On 7/27, the Evaporator area took a planned outage to
address the leaking shell. All repairs were made at that
time to stop the leak. After the planned outage, influent
color to the WWTP improved.
27 Sep 2016 172,736 Ibs/day 1 1-day UAL — Immediate Corrective Action
Cause and Corrective Actions} — BMP event. During a
routine outage of the #11 Recovery Boiler, liquor inventory
levels became elevated. The cyclones had been in wash
mode for approximately 17 hours. The wash material was
thought to be dilute and could be released to the sewer
without significant impact to color levels. Conductivity was
not checked and the material was released. WWTP
personnel observed the elevated color material in the low
lift and diverted the flow into the #1 spare clarifier.
Recovery operations were notified and the source was
stopped. The material captured in the clarifier was then
batch treated and released back into the treatment process
at a non -disruptive rate.
29 Nov 2016 184,846 Ibs/day 11-day UAL — Immediate Corrective Action
Cause and Corrective Actions} — Non-BMP event. The #4
kiln was being washed because of an accumulation of hard
material inside the kiln and because the ID fan needed to
be sand blasted and balanced. Two hour colors samples
do not correlate with the elevated influent color number for
that day. Operators observed turbidity interference within
the cuvet prior to analysis. Secondary effluent color did not
show the expected effect had the number the influent
number been elevated.

Cause and Corrective Actions} — BMP Event. During a
cyclone wash of the #10 Recovery Boiler the Mix Tank
overflowed. The boiler's sump gate was in the closed
position but elevated color material was observed
downstream of this point. The boiler sump had been put
into manual mode to help manage inventories in the sump
recovery system. Although the material was being held in
the u-drain system some of this material continued to leak
by the gate. Once observed operators turned the sump
back into automatic mode and collected the material.
Sandbags were placed to prevent any other material from
entering the sewer system. After the outage was complete,
the sandbags were removed and the gate and channel
were cleaned. Once put back into service no leaks were
detected around the gate.
Other observations around the mill were that the MRP
system for the Pulp Mill was down at this time for
maintenance. The system was brought back online on
12/15 after maintenance was completed. The #7 digester
liquor heater had also developed a leak and showed spikes
in conductivity in the Hog Line. This digester was
immediately taken out of service and repaired.
