Culp, Inc. (Culp Ticking Facility)
Stokesdale, North Carolina
Dear Ms. Chandler:
NC Department of
Environmental Quality
Received
MAY 3 1 2019
Winston-Salem
Regional Office
As we have discussed, the Culp Ticking facility is proposing to modify equipment covered under the
above referenced permit.
CHANGES TO PERMIT NO. WQ000962
a) The current permit contains the language "two evaporators with a catch basin". One of the
two evaporators have been removed from service. The replacement of the second
evaporator is proposed. A complete set of plans and specifications for the replacement unit
is attached in Appendix A. Note that this is a one -for -one replacement. No new
evaporation equipment is proposed.
b) The current permit does not specify the details for secondary containment surrounding the
evaporator and its associated catch basin. Plans have been made to install a concrete
secondary containment structure to supplement the existing earthen berm. Note that the
secondary containment will be constructed outside of the one hundred foot set -back from
the stream bed. An approximate location for the containment structure is attached in
Appendix B. Calculations indicating the approximately containment capacity are also
attached.
c) The existing permit includes a flow rate of 130,000 gallons per day. It is requested that the
revised permit include a flow rate of 20,000 gallons per day.
d) Form 06-16 has been completed and is attached in Appendix C.

e) The description of equipment contained in the current permit is accurate with three
adjustments. Aerial photos showing the relative location of the equipment is attached in
Appendix D. Photographs of the actual equipment are attached as well.
1) The finished water storage tank is 50,000 gallons, not 45,000 gallons.
2) The equalization tank is 20,000 gallons, not 27,700 gallons.
3) The automatic dry treatment chemistry feed system has an auger lift, not a vacuum
lift.
CHANGES TO ANCILLARY PORTIONS OF THE TREATMENT SYSTEM
a) The security fencing surrounding the outside portions of the wastewater system will be
installed upon the completion of the new concrete secondary containment. An as -built
drawing of the fencing will be prepared upon completion and this drawing will be
maintained on -site.
b) An air injection system has been added to the finished water tank serving the
evaporator. This system is intended to stir and aerate the water to eliminate nuisance
conditions, primarily odor.
It is anticipated that the above information is sufficient to respond to all questions raised by the North
Carolina Division of Environmental Quality. If more information is needed, please advise. It is the
intention of Culp, Inc. to operate the Culp Ticking facility in full and continuous compliance with all
environmental regulations.
Thank you for the assistance and support of your staff.
Sincerely,
CULP, INC.

Design Features
Two SpeeA Motors
For those installations requiring close control, two
speed 1800/900 RPM motors are an excellent
method of capacity control. This agrras emerlt gives.
capacity steps of 10% (fans off), 60% (fans half-
speed) and 100%. A temperature controller can be
supplied to set control steps at 511, so fairly close
temperature control can be maintained without
excessive cycling of the fan motor.
Two speed motors also save operating costs. At
half -speed, the motor draws less than 15% of full
load power. Since. maximum wet bulb and maxi-
mum load very seldom coincide, the cooling tower
will actually operate at half -speed as much as 80%
of the time. Thus,. power costs will be reduced by
a00*imMely_05% during the major portion of the
A third advantage of'two-speed motors is that noise
levels are reduced b 6 to 8 d0 when operating at
half speed, Since f oh the. load pnd.the .wet bulb
are normally lower at night, the tower will oper7te at
low speed and the noise level will be substantially
reduced during this noise sensitive period.
Inverter Duty..Motors
EVAPOO recommends theuse of 'Invierter Duty
Motors when Variable Frequency [gives are
utilized for gapacity control. Inverter Duty: Motors
are available as An option.
Accessibility
The pan/fan section of a centrifugal fan unit Is
designed for accessibility and matr►t0hance. Fan
and. drive components. are positioned to allow easy
adlustmenf and cleaiiing.. All grease fittings are in
convenient looations for periodic lubneation.

PAN SECTION ACCESSIBILITY
Large ciroular access doors are provided on each
section to allow entry into the pan. All float valve
and strainer assemblies are located near the door
for easx.adjustment and cleaning' The pan sump is
designed to catch the dirt accuinu►ated .and cart be
flushed out_with . hose.
PVC Eliminators

EVAIRA10. Cooling Tower Pill
The patented" EVAPW fill design used in the
forcer draft idociling tower line is the culmination of
thousands of iiours.of.research and testing
conducted byE-VAPCOs research engineers. This
program f ias produced a cooling. tower fill with
superior heat transfer, rec(uced channeling in flow
passages, improved drip enhancement for lower
air side pressure drop"and exceptional structural
strength.
The fill is specially designed to induce, highly
turbulent. mixing of the air and water for heat
transfer: This is made possible by forming the raw
fill Into corrugated panels.on which there are small
ridges.. These ridges serve many purposes, one of
Which is to create a' itation in both the water and
the air in the tower. This increase Jr!turbulence
prevents channeling of the water and promotes
hatter mixing of air and water, therefore improving
heat transfer. lh addition, special. drainage tips
allow high wateT loadings without excessive
pressure drop,
The fill is constructed of inert polyvinyl chloride,
(PVC). Ii will not rot or decay and .is formulated to
withstand water temperatures of 130'P. The fill
also has excellent fire resistant qualities providing
a flame spread rating of 5 per ASTM=1584$1a.
(The flame spread .rating scale Tangos from 0 for
non-combustible to 100 for highly combustible).
Because of,the unique way lti which the crossfluted
sheets are bonded to'ether, the structural integrity
of the fill is greatly enhanced, making the fill usable
as a working platform.
A high temperature fill is available for water
temperature$ exceeding 13p°F. Consult your
EVAPCO representative for further details,

Pan Freeze Protection Electric Water Level Control
Remote Sump
Whenever at cooiino tower is idle during sub -freezing
weather, the water in the sump must be protected from
freezing and damaging tale pan. The simplest and
most reliable method of accixnplishing this is with a
remote sump, tank located in a heated space in the
building under the. tovier, With this system, the water
in the tower drains to the indoor tank whenever the
pump is shut=oil. When a tower is ordered for remote
sump bpe"ration, the standard float valve and strainer
are omitted, and the unit is provided with an oversized
water out connection. When a remote sump is not
possible., a supplementary means of heating the pan
water must be provided.
Electric Heaters
Electric immersion heaters are available factory
installed in the basin of the tower They are sized to
maintain a +40'1- pan water temperature `at 00F
ambient withthe fans off. They are furnished with a
combinatlon tharmostatllow water.protection device to
cycle the heater on when required and to prevent the
heater elements from energizing unless.they are com-
pletely submerged. All components are enclosed in
rugged, weatherproof enclosures for-Qutdooruse.
Heater control -packages; are available as an opfion.

Steam or Hot Water Coils
Pan coils are available. as an aftemate. to the electric
heaters , des cribed above. Constructed of galvanized
pipe installed in the cooling tower basin,. they are
supplied less controls and are ready for piping to
an external steamor hot water source. Pan water
heater controls should be interlocked with the water
circulating 'pucrtp to prevent their operation when the
pump is energized.
E . ARCO LSTA Cooling Towers are available with an
optional electric water level control system in place of
the standard mechanical makeup valve. and float
assembly, This: package provides at;curate control of
the pan water level and does not require field
adjustment, even under widely variable.oporating
conditions.
The control was designed by EVAPCO and consists of
multiple.heavy duty stainless steel electrodes. These
electrodes are mounted external to the unit in a vertical
stand pipe. Fqr, Winter operation, the stand pipe must
be wrapped with electric heading cable -and insulated
to protect it froth freezing. The weather protected
slow closing solenoid valve for the makeup water
connection is factory supplied and is ready for piping
to a water supply with a.pressure between 20 psig
(minirrium)and 50 psig. (maximum).
Vibration Isolators
The fans on EVAPCO cooling towers. are balanced and
run virtually vibration free. In addition, the notating
mass is very small In relation to the total mass of the
cooling tower, further reducing the 00ibiliity of
objectionable vibration being transmitted to the
building structure. As a result, vibrAti6h isolation is
generally not required:
In those .cases where, it is determined that vibration
isoation is necessary, spring type vibration isolator rails
can be furnished. The rails are constructed of heavy
gauge 0-235 hot -dip galvanized. steel for superior
corrosion resistance, Rails are designed to be
mounted between the,cooling tower and the
supporting steel framework. They are 90% efficient
and have approximately 1' static deflection. Rails are
designed _for wind loading up to 50 mph:
It is important to note that vibration isolation rust be
installed continuously along the full length of the
cooling lower on both sides of the unit. Point isolators
mayy be used between the supporting steel and the
building framework, but not betweenthe;:unit and the
supporting steal.
Screened Bottom Panels
Protective inlet screens are provided on the front of the
fan section on the LSTA Screens are not provided on
the bottom oft . Oar section since most units are
mounted on the roof or at.ground level.
If units are.installed in an elevated, position, bottom
screens are recommended fcr safety protection.

Secondary containment parameters:
40 feet in diameter
5 feet wall height
Total volume of containment: 47,000 gallons
Total retention capacity at 20,000 gallons per day = 2.4 days
Assuming that 2 feet is reserved for precipitation capacity and assuming that the average flow is 12,000
gallons per day, the system will have a typical, average storage capacity of 2.3 days.
It is concluded that the proposed parameters will provide sufficient safety from a release to the
environment during any foreseeable conditions.
The exact parameters will be dependent on conditions encountered during construction. A complete as -
build drawing will be prepared following completion of the construction activities.
