I. Location: Hornwood, Inc is located at Pit Road, SR 1812 in Lilesville,NC.Anson County.

Directions: From FRO,take Hwy 401 S to Wagram,then right on Wire Road past Laurel Hill, and turn
right(west)onto Hwy'74. Go past Rockingham 5 miles to Hailey's Ferry Rd/SR 1801 /Pit Road on the
left. After turning,WR Bonsal is on the left. Go for— 1/4 miles to Hornwood on the right.
II. Description: Hornwood,Inc is a textile company that warps,weaves, dyes yarn,and heat-sets(tenter
frame finishes)and doffs(textures)nylon and polyester knit fabrics. They produce baseball uniforms,
automoble seat fabric, cloth for reverse osmosis water purification, gauze(currently their largest seller),
liners for tennis shoes, and cowboy shirts to name a few. The last compliance inspection was on 22 May
2013 by Robert Hayden.
Safety: Standard FRO safety equipment required. Plant personnel do not wear helmets. Boilers,high
pressure steam leaks,and associated hot piping are the principal hazards.Do not put fingers in the looms
or fabric handlers on either side of the tenters.
Current throughputs: There facility traditionally employs about 360 people and operates 24 hrs/day, 5
or 6 days/wk, 50 wks/yr. Business is slightly up from last year. The"through-tenters"number(best
measure of production) in 2013 was 10,312,041 lbs.

Operation
IV. Initial Conference: On 22 May 2013, I,Robert Hayden,FRO DAQ, met with Mr.Kenneth
Horne Jr. We verified all FacFinder information. Mr.Home said that there had been no changes in
processes,equipment or formulations since the last inspection. Business is relatively good,but there
seems to be a dramatic drop in the demand for football-related clothing,presumably because of reduced
school revenue.
V. Process Description: This process may be divided into several distinct operations and are
discussed as follows:
a.Warping: Yarn is spun onto a single spool for processing in the knitting room. Yarn may also
be draw warped which draws the diameter of the yarn down by heat and tension. Draw warping
effectively reduces the size of the yarn.
b. Knitting Room: Spools go onto a mandrel that feeds the knitting machines.
c. Middle Warehouse: This is where both finished and unfinished fabric is stored until either
future processing is done or shipped to the customer.
d.Dye House: Dye is added to the fabric in one of two processes,beam or jet dying. In beam
dying,fabric is wound onto a beam with holes that allow the dye to pass through. The dye
solution is pumped from the rear of the chamber and passes through holes in the beam and out
through the fabric. In jet dying,the cloth is pulled through a tube in the top of the dye chamber
by means of a roller and dye water and is constantly in motion through a solution in the bottom of
the chamber. They are now adding fire retardant here to reduce VE in the tenter frame.
e. Finishing: Here,cloth is passed through one of four tenter frames which heat sets the fabric to
reduce shrinking and stretching, and add chemicals which stiffen or coat the material.
f.Napping: One of three things may be performed on the material during this process. The
fabric will be napped which gives it the appearance of fleece, or shearing which cuts off the top
of the fleece, or sueded which sands the fabric.

g. Mist Eliminators: The exhaust air from the tenter frames flows through a pre-filter that takes
out some of the dry particles with a one inch fiberglass mesh using two trays to pass the air
through. They change these daily. Next,the air passes over six cold water coils that helps
condense the vapor and send it through the mist eliminator. The coils are washed daily and taken
out quarterly for washing. They discovered a problem with the pipes leading to the coils that had
to do with pipe threads. They have ordered new pipes so that the coils won't have to be replaced.
The mist eliminator houses 18 two-inch fiberglass cylinders that are surrounded by a wire mesh.
The condensed vapor passes through the center of the filter then proceeds out the stack. The
filters have to be cleaned during a shut down. They have had to replace the filters once already
because of epoxy buildup. A different surfactant is being used now that helps cut through the
epoxy, but they must first soak the filters weekly. Jet nozzles are located at the bottom center of
each filter tube and spray wash water into each. The rinse water is collected at the bottom of the
collector unit and sent through a trap to a holding tank for collection and disposal.
V. Inspection Summary: I checked the NSPS requirements for boiler B-3. When limited to natural
gas,there are few requirements and few opportunities for noncompliance. We checked VE from the
operating boilers(zero)and from the two condenser stacks prior to entering the plant. We toured the plant
with Mr.Kelly and confirmed the accuracy of the permit and that there were no unpermitted sources.
Two boilers were operating on NG. Both tenter/condenser stacks were emitting something,but as in the
last four years,the sun position,background, and complexity of the emission stream(vapor percentage)
all complicate a valid VEE. This year the background clouds were the same color as the plume,rendering
it virtually invisible. The nature of their synthetic products, especially the ROWPU's cured epoxy
membrane, creates some smoke. The condenser maintenance logs were very good.
VI. Stipulation Review:
2D.503 Particulate from combustion.
Compliance Indicated The boilers have been operating on natural gas for the last two years and AP-42
emission factors indicate compliance.
2D.0515 Particulate control from miscellaneous processes(tenters,presumably).
Compliance Indicated. Determined at initial permit review. Likely has improved with condensers.
2D..0516 Sulfur Dioxide control.
Compliance Indicated. The boilers were operating on natural gas on the day of the inspection. When
fuel oil is combusted,NSPS Dc requires sulfur content no greater than 0.5%.
2D.0521 Visible Emissions control
Compliance Indicated, but not positive. VE from the condenser controlling tenter frames 3 and 4
appeared to be around 40%.. This stream,however, has a water vapor content,which does not separate
from the smoke plume,greatly complicating a valid VEE.
2D.0524 NSPS fuel monitoring and recording only reqt when burning NG).
Appeared In Compliance. No oil combusted since last inspection. Fuel records showed xxxx therms of
NG combusted in 2012.
2D.0611 —Condenser/Mist Eliminator Requirements. Elements of the logbook include: annual internal
inspection-Inspect and maintain structural integrity of duct work and piping leading to and coming from
condenser/mist eliminator. Change pre-filter once per week. Implement wash procedure when the
pressure drop across the fiberglass Mist Eliminator increases to 7.5 to 8.0 inches of water. Implement

wash procedure when pressure drop across water coils increases to 3.0 inches of water. Weight of both
the oil and particulate material collected in the condenser/mist eliminator weekly.
Compliance Indicated. Maintenance checks are done several times daily on the condenser/mist
eliminators when operating. Twice yearly they are internally checked for problems. The filters are
changed weekly. The facility has not had the any problems will pressure drops on the fiberglass mist
eliminator but one is washed daily and the other weekly just to make sure.
2D.0958(c)Work Practices.
Compliance Indicated. No rags,buckets or containers with VOC containing materials were left open or
unsealed. Very little solvent in use.
2D.1806 Control and Prohibition of Odorous Emissions.
Compliance Indicated. No offensive odors were noticed on either side of the property.
2D.0540 Dust Control
Compliance Indicated. No dust was seen on the entrance of the facility or in the roadway.Most surfaces
are paved.
20.0711 Toxic Air Pollutant Emission Limit.
Compliance Indicated. No applicable changes in operating rate or formulations since last permit review.
Therefore they are incompliance from review done during their permit application process.
VH.> Chemical Accident Prevention/112R Status: Homwood does not use or store store any
regulated chemicals in amounts that would necessitate a written Risk Management Program.
V1I. Compliance History: None in last 5 years.
VHI. Comments and Recommendations:
1. Plant should research tenter operating parameters to maybe reduce opacity; condenser stacks are
difficult to read,but may exceed limits. Perhaps inspect early or late in the day, or under unusual
meteorological conditions to attempt a better VE read(with detached vapor plume),
2. Boilers should be labeled as to ID, size and mfg date (at least ID). Past permit reviews indicate that
the boilers from left to right, as observed from outside, are 01, Main 032,Main 031 and 03.
3. Hornwood appeared to be in compliance on 25 March 2014.
