After being re -stacked, it will be tagged with the name, grade of lumber, thickness, and species
of lumber. The lumber will then be placed in the kiln to dry. After the lumber is dried it goes
down the line in the SFD building, where it is graded and restacked according to the grade
length, and species of lumber. The lumber will then be stored in the dry shed until picked up
by the vendor.

Question #7 describe the treatment system.
Wilderness NC, Inc., Waste Water Treatment Facility
05/18/19
Wilderness NC, Inc. operates a 0.0125 MGS extended aeration wastewater treatment system
consisting of the following components:
• Aeration chamber
• Sludge holding tank
• Clarifier
• Recirculating sand filter
• 5:1 flow splitter
• 1500-gallon recirculation tank with air diffuser
• Filter screens
• Dual pumps
• Tablet chlorination and de -chlorination
• Fifty-four (54) day polishing pond
Wastewater flows from the plant into the aeration chamber via gravity. After aeration,
wastewater flows either to the pump tank or polishing pond. During normal operation (April to
October), wastewater flows from the aeration chamber to the pump tank and then is pumped to
the recirculating sand filter. Wastewater is diverted to the pond during winter months
(November to March) to avoid high ammonia typical during winter months. Water from the pond
is returned to the pump tank at approximately the same rate. From the pump tank, wastewater
is pumped into the recirculation sand filter. Effluent from the sand filter is split 4 to 1 with 3/4th
of the flow being returned to the pump tank and 1/4th being discharged.
Discharge is domestic wastewater, boiler blow down, and kiln condensate.

General Overview
The wastewater treatment plant at Wilderness -NC, Inc., SFD/64 Lumber plant treats
approximately 2000 gallons per day. The treatment system consist of an aeration
chamber, pump tank, polishing pond, recirculating sand filter, tablet chlorination and
dechlorination. Wastewater flows from the plant into the aeration chamber.via;gravity.
After aeration, wastewater flows either to the pump tank or the polishing pond. During
normal operation (April to October); wastewater flows from the aeration chamber to the
pump tank, and them pumped to the recirculating sand filter. Wastewater is: diverted -to
the pond during winter months (November to March) to avoid high ammonia typical
during winter months. Water form the pond is returned .to the pump tank at
approximately the same rate. From the pump tank, wastewater is pumped into the
recirculating sand filter. Effluent from.the sand filter is split 4 to 1 with 4/P of the flow
being returned to the pump tank and 115" being discharged. The North Carolina
Department of Environment and Natural Resources, NPDS Permit No.. NC0023604,
permit the discharge of the effluent.
This Operation and Maintenance (O&M) manual intends to set forth guidelines and
procedures for the wastewater treatment system. OST based these guidelines on the
NPDES seasonal effluent limitations and past experiences with system performances.
Occasionally, this O&M manual may need to be updated to :comply with effluent.
requirements. A system flow land construction diagram is included with this O&M
manual.

Diverting Flow to Polishing Pond
Under normal operating conditions (April to October), wastewater flows from the
aeration. chamber to the pump tank: During this operating period, anunonia.effluent
limits (per the NPDES permit) are 2.0 mg/1 (monthly average). The ammonia effluent
limits from November to March are increased to; 4.0 mg/1 (monthly average)..
Historically, high ammonia results are seen in .the winter months. Therefore; beginning
on November, flow should be diverted to incorporate the polishing pond.
To .Divert to. -the Pond
1. Two 44nch ductile iron gate valves are located between the aeration chamber and the
pump tank. To divert flow to the pond, open the gate valve on the discharge: line
flowing to the pond.
2. Close the gate valve on the discharge line flowing to the pump tank.
Water is pumped from the pond back into the pump tank using a transfer pump and must
be activated on the same winter/summer schedule above. The transfer.pump supplies
water to the pump when activated, and to a yard hydrant for use at any time. 'A timer
located at the :pump tank activates a solenoid valve that allows pond water to flow to the
.. pump tank.
To Divert from the Pond to the Pump Tank -
1. Engage the time by sitting the timer to activate the pump
2. The pump should be activated 4 times per day and run for % hour. (Note: -The
pump will be able to pump approximately 200 gallons in a V2 hour.) The pump
needs to be running while the operator is perfom- ung.his daily site check. (Note: The
pump activation schedule may need to be altered depending on flow and associated
r." 2

pond levels.)
3. The pressure switch on the transfer pump should be set at 30 psi.
High and low level probes control the pump tank wastewater levels. The piobes will
automatically tum on/offthe pump in the pump tank. Wastewater from the pump tank
flows into the recirculating sand filter and by gravity returns to the pump tank or is
discharged. 'Prior to discharge, the effluent flows through a chlorinator and then a
dechlorinator.
