(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.

M Low Installed Costs The LSTA forced draft cooling tower is designed using a modular concept to miriiml;t6 rigging, piping and support costs. All major components are factory assembled into corriffiete sections. Fans, shafts, bearings and drives are installed and aligned at the fa6tofy as an integral part of the pan section se to eliminate the for necessity of he field ri,� ging fre- these dy parts. & J I 0 I] Fan Motors All LSTA models utilize heavy duty totally enclosed fan motors iT.E.F itr) designedspecifically for cool- ing tower applications In addition; EVAPCO offers Many :opliohal motors t6 rri et your specific needs, including: • Premlurn Efficiency Motors • Multi -Speed Motors • Inverter-DUty Motors.for VFD Applications Fan Motor Location EVAPCO mounts the fan motor in a convenient. open area to make it easy to adjustbelt tension; lubiicate the motor; electrically connect it, or :change the M010r if heoessary. The fan motor and drive are under a ppros otective cover for safety purpes and to :protect rt ..i6 i5 from the elements. LARGE SERIES MOTOR MOUNT SMALL SERIES MOTOR MOUNT Centrifugal Fan Assembly Faris on the LSTA. models are of the forward curved centrifugal type with hdf-dip galvanized steel construction. All fans are statically and dynamically balanced.and mounted In a hot -dip galvanized steel housing designed and manufactured by EVAPCO. CENTRINGAL WHEEL Forged Bearing Journal The fan shafts. used on all LSTA models are stan- dard. with forged bearing journals. The competition's design utilizes:a two-piece fan shaft with welded end journals,1hat is guscoptible to rusting and eventual failure. The solid forged. design of the LSTA fan shaft provides durable long-lasting operation, free from pre -mature mechanical failure. 5 LSTA 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. j t C': it. r l 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 The final elepient in the upper.pari of the cooling tower are moisture eliminators which strip the entrain ed Water 5" deep, spaced on 1" centers: They incorporate a hooked leavinv edge designed to. direct the ELIMINATOR discharge. air shear away fttini the fans to help eliminate recirculation of hot, saturaled air back into the fan inlets. The air discharge side of the cooling.tower is the most corrosive and 0ndst.difficult arts to clean and refinish. To provtde'the greatest. protection in this area, the drift eliminators are made of. Inert polyvinyl chloride (PVC): The PVC material will effectively eliminate corrosion of these vital components and is specially treated to resist ultraviolet light. The eliminators are assembled in easilyhandled sections to facilitate. removal. This will expose the entire upper portion of the unit and water distribution system for periodic inspection. Stainless Steel Strainers One other component of evaporative cooling equipment which is Subject to.excessive wear is the suction strainer. EVAPCO provides a - ype 304 stainless steel strainer a0 all units taxcept remote sump applications) as stendard—Strainers are positioned around a large anti -vortex hood in easily handled sections. STRAINER !U.S. Patent No. 4,500,330 U t ;i EVAPCOAT; G-235 Hot=pip Galvanized Steel Construotioh The: standard material of construction for evaporative coolinQ equipment.for many years has been hot -dip galvanized steel. The purpose of galvanizing is to protect the base metal from corrosion, and the thickhess of the galvanized layer directly affects the equipment life. EVAPCO has been instrumental in the development of corrosion protection technology and was the first manufacturer to use 0-235 galvanized steel construction. The 6-235 designation equates to a minlmurn of 2.35 ounce's of zinc per;square foot of surface area.

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.

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.

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 .
