The morning of the field portion of the compliance assurance visit(CAV)on December 1,2020,1
completed the NC Employee Screening for Employees Reporting Onsite form on the oshr.nc.gov web site
Based on my responses to the questions in this form, I was able to proceed with the onsite CAV. The
compliance assurance visit(CAV)was conducted by me outside of this facility. I met with Ms. Owens
and Mr.Kevin Hefner,president,to conduct the inspection. Mr. Hefner escorted me outside of this
facility to the two cyclones and the exhaust of the three-sided sanding booth. Both Mr. Hefner and I wore
a face covering and maintained a distance of more than six feet(social distancing) from each other during
the CAV.

Compliance Assurance Visit:
1. General Information:
The purpose of this site visit was to conduct a routine compliance assurance visit(CAV). This
facility manufactures wooden furniture frames. This company operates this plant from 6:30 am
to 2:30 pm, 5 days per week(Monday through Friday), 50 weeks per year for the woodworking
and gluing operations. Mr.Kevin Hefner,president,accompanied me during the CAV.
2. Facility Contact Information:
During the inspection, I verified the facility contact information in IBEAM with Mr. Hefner. No
changes to the facility contacts are needed in IBEAM.
3. Compliance history file review:
No problems have been noted in the last five years by DAQ prior to this visit. The current
compliance status is discussed in the following sections.
4. Source Observations:
This facility has one cyclone (144 inches in diameter) installed on woodworking equipment with
associated storage silo and truck trailer, and one cyclone(88 inches in diameter)installed on a
grinder. hi the main plant of this facility,woodworking equipment consisting of routers and saws
vent woodwaste to the cyclone(144 inches in diameter) and then into truck trailers or a storage
silo. The storage silo had been used as an emergency alternative if the truck trailers are full. Mr.
Hefner stated that the storage silo is no longer being used by this facility. An augering system is
used to transfer the woodwaste from the cyclone to two truck trailers located on either end of this
system. The truck trailers are equipped with bin indicators that identify when the trailers are full
of woodwaste. Mr. Hefner stated that two truck loads of woodwaste are collected every other
day. Each truck trailer weighs approximately 15 tons. The woodwaste is sold by this company
as boiler fuel and shipped to customers.
The larger scraps of wood are conveyed to a vibrating shaker table and then to a grinder. Any
woodwaste from the grinder is vented to the cyclone. This company uses the same augering
system as described in the above referenced process to transfer the woodwaste from the cyclone
(88 inches in diameter)to the truck trailers.
The woodwaste from the woodworking operations and grinder appeared to be properly controlled
by each cyclone. The exhausts of each cyclone is horizontal and uncapped. The two cyclones,
grinder, various woodworking equipment and augering system were in operation during the visit.
I observed no visible emissions from the two cyclones, grinder,various woodworking equipment,
augering system, truck trailers, or associated ductwork during the visit. The visible emissions
from these sources are limited to 20 percent opacity when averaged over a six-minute period.
These sources were not exceeding the 20 percent opacity limit during the visit.
This company uses two wood glues (assemby 433 and titebond 111)by the manufacturer, Franklin
International, to assemble the furniture frames. The copies of the SDS are located in the file of
this facility. The wood glue, assembly 433, is purchased in totes. Each tote contains 2,535
pounds of glue and the glue weighs 9.77 pounds per gallon. The glue has 0.029 pounds per

gallon of VOC as indicated on the SDS. The wood glue, titebond 111, is purchased in buckets.
Each bucket contains 5 gallons of glue. The glue has 0.4 pounds per gallon of VOC (ethylene
glycol) in product as indicated on the SDS. Mr. Hefner stated that furniture frames was being
glued at the time of this visit. I observed no visible emissions or detected any emissions from the
gluing operations outside of this facility during this visit.
This company reported during the last air emissions inventory for calendar year 2012 that the
actual VOC emissions from a furniture leg dip process were 55.5 pounds. It was noted in an
inspection report dated October 30, 2014 that furniture legs were dipped in a bucket and legs air
dried on a rack. During this visit, Mr. Hefner stated that the furniture leg dip station is no longer
being conducted at this facility. No furniture leg dip station was observed by me at this facility.
This facility has a three-sided booth that had been used for conducting touch-up/quality control
sanding. The booth has a fan that exhausts through a vertical and capped stack to the outdoor
atmosphere. Mr. Hefner stated that the booth is no longer being used. I observed no visible
emissions from the vertical and capped exhaust of the three-sided sanding booth located on the
roof of this facility.
This office has not received any fugitive dust emissions complaints regarding this facility. This
company has paved roads at this facility. During the visit,I observed no fugitive dust from this
facility. I asked Mr. Hefner if any excess emissions had occurred at this facility since the last
inspection on October 31,2018. Mr. Hefner stated that no excess emissions had occurred at this
facility.
5. NSPS/NESHAP Review:
This facility is not subject to any NSPS or NESHAP regulations. There are no emergency or
peak shaving generators,fire pump engines or gasoline storage tanks at this facility.
6. Exemption Qualification:
This facility submitted a request to rescind Air Permit No. 07896R07, since the actual facility-wide
emissions of particulate matter(PM10), sulfur dioxide,nitrogen oxides,volatile organic compounds,
carbon monoxide,hazardous air pollutants(HAP) and toxic air pollutants(TAP), each are less than
five tons per year and the total actual aggregate emissions of these pollutants are less than ten tons
per year.
During the exemption review by the permit engineer,this company provided information on the
amount of woodwaste(wood chips) generated by woodworking operations and the grinder. The
amount of wood chips sold as boiler fuel was 748.26 tons in 2012; 1,111.93 tons in 2013; 1,365.44
tons in 2014; 1,300.79 in 2015 and 766.756 tons from January 1 to August 30,2016. The wood glue
was not evaluated by MRO DAQ permitting during the exemption review.
The highest amount of wood chips produced in 2014 was used to calculate the facility-wide actual
PM10 emissions. It was determined that 35%of the wood chips is from routing/rough sawing(95%
shaving/chipping and 5%sawing) and 65%of the wood chips is from the grinder(100%milling&
hog). The actual amount of woodwaste (wood chips)generated was 477.925 tons for routing/rough
sawing and 887.575 tons for grinding. The DAQ woodworking emissions spreadsheet was used to
calculate the actual facility-wide PM10 emissions as 0.27 tons per year. All PM10 emissions
emitted were from routing/rough sawing. The grinder only produced PM emissions.

This office sent a letter dated October 11,2016 exempting this facility from permit since the facility-
wide actual particulate emissions(PM10),VOCs,HAPs, and TAPs are less than five tons per year
and total aggregate emissions are less than ten tons per year.
This company is keeping records of the actual tons of woodwaste (wood chips)generated and the
pounds or gallons of wood glue used. Ms. Owens emailed me the usage of the woodwaste(wood
chips) and glues in 2018,2019 and January 1 through October 31,2020. The woodwaste(wood
chips) shipped for boiler fuel was 1,724.54 tons in 2018; 1,482.94 in 2019 and 1,434.88 from
January 1 through October 31,2020. The wood glue usage for assemby 433 was 35,490 pounds in
2018; 53,235 pounds in 2019 and 22,815 pounds from January 1 through September 15,2020. The
wood glue usage for titebond III was 40 gallons in 2018; 75 gallons in 2019 and 90 gallons from
January 1 through September 15,2020. The usage records for the woodwaste(wood chips)and
wood glues indicate that this facility still qualifies for exemption under 15A NCAC 2Q .0102(d).
This facility has not changed or modified the equipment to increase emissions above the exemption
thresholds since the rescission request.
6. Compliance determination:
Based on my observations, this facility appeared to be in compliance with the air quality rules
(21) .0521-visible emissions; 2D .0512-particulates from wood products finishing plants; 2D
.0535-excess emissions and 2D .0540-fugitive dust emissions) at the time of the visit. The
compliance assurance visit checklist is attached on page 6.
