3. Zoning
The permit application received on 03/28/2022 included a request for a Zoning Consistency
Determination from the Anson County Zoning and Planning Department dated 03/22/2022. The
determination was signed by Larry Newton, Planning Director, dated 03/29/2022, indicating that
"The proposed operation IS consistent with applicable zoning ordinances. "
4. Application Chronology
Date Activity .
02/10/2022 Mike Thomas of FRO DAQ inspected the facility and found it to be in
apparent violation for installing and operating a 16 mmBtu/hr Natural
gas-fired boiler without first obtaining a permit. This source cannot be
exempt from permitting since the wood-fired boiler was modeled and this
new source has common pollutants. Therefore, a permit is required.
02/28/2022 NOV issued for installing and operating the 16mmBtu/hr natural gas-fired
boiler without first obtaining a permit is a violation of N.C.G.S. 143-
215.108.
03/18/2022' Jeffrey Cole spoke with Daryl H. Grassick, an Air Quality Consultant for
Edwards Wood Products. Mr. Grassick asked if the facility would need to
model again because they installed the NG-fired boiler. Mr. Cole explained
that the natural gas-fired boiler was not exempt from permitting(02Q
.0102(b)(2)). If the facility wanted both the boilers to operate at the same
time,then they would need to remodel for toxics. This was due to the '
combined expected actual emissions(as TPERs had been exceeded for the
wood-fired boiler originally and the NG-fired boiler emissions would add
to those emissions).
03/18/2022 Jeffrey Cole confirmed with Tom Anderson that if the facility requested a
stipulation restricting operations to one boiler at a time, they would not
need to remodel for toxics. This was due to the NG-fired boiler emissions
alone not exceeding TPER.
_- --____
03/28/2022 FRO received the application for modification of the air permit. The
application included a properly completed Form A and a check in the
amount of$50 for the applicable permit processing fees. There was no
request to keep any information confidential. The application appeared to
be complete for processing.
03/29/2022 FRO sent the facility a letter acknowledging receipt of the permit
application.
03/31/2022 The permit application was forwarde 11 d to the permit engineer.

5. Changes in Equipment, Emissions and Regulations and PE Review Requirements
This permit modification application is for the following changes to the current air permit:
• Add one natural gas-fired boiler(rated at 16.739 mmBtu/hr maximum heat input).
• Corrections to existing permit source ES-2(in permit R03 listed as Four(4)steam-heated
lumber drying kilns(62,000 board feet capacity each))based on changes at the plant not
reflected in the current permit. The facility requested removal of two of the four
steam-heated lumber drying kilns(62,000 board feet capacity each; from ID No. ES-2)that
were never installed at the site.
• Delete emission source ES-4(in permit R-3 listed as"Two(2)steam-heated lumber drying
kilns, 62,000 board feet capacity each")from the permit. The facility indicated these kilns
have been relocated to Edwards Wood Products,Inc.Laurinburg plant.
There is one relevant pink sheet item to be addressed in this permit revision.
• "Facility may want to remove some of the kilns listed on the permit that are not installed.
Engineer should confirm with facility during next permit mod or renewal." The facility
requested a correction in this modification application to existing permit source ES-2 to
indicate two(2) steam-heated lumber drying kilns rather than four.
A 02D .1100"Control of Toxic Air Pollutants"Ad-Hoc Operational Restriction has been
incorporated into the permit: "The Permittee shall only operate either the Natural gas-fired boiler
(16.739 mmBtu/hr maximum heat input) (ID No. ES-S) or the Stoker type wood-fired Boiler(10.54
mmBtu/hr maximum heat input(300 BHP)) (ID No. ES-1), not both simultaneously, to ensure
emissions do not exceed Toxic Permit Emission Rates (TPERs)."
The latest updated permit condition for 15A NCAC 02D .0521 "Control of Visible Emissions" has
been incorporated into the permit.
The latest updated permit condition for 15A NCAC 02D .1 100 "Toxics Above TPER Limits" has
been incorporated into the permit.
PE Seal—A PE Seal was not required for this application.

6. Background
The following information is excerpted from the Permit R03 Review on 11/29/2017 by Greg Reeves.
A review of the toxics emissions submitted with their 05/06/16 permit renewal and administrative
amendment package showed that the facility projected actual emissions (based on emissions from the
wood-fired boiler [ID No. ES-I] only as steam heated kilns only emit VOCs)would exceed the TPER
for several toxic pollutants, specifically, arsenic, benzene, chromium. This required the facility to
perform an air dispersion analysis to demonstrate compliance with the AALs for these pollutants.
Data was supplied by the company regarding emissions, emission locations, and terrain, and RCO
AQAB performed a dispersion modeling analysis based on this data. Emission rates were not
optimized for maximum allowable AALs. The results of this modeling analysis were as follows:
Concentration at AAL o L
x
Pollutant Emission Rate Property Boundary (µg�m3) /o AA
(ftg/m )
Arsenic 2.03 lbs/yr 1.3 8 E-04 0.0021 6.6
_
Benzene 387.81bs/yr 2.63E-02 0.12 21.9
Chromium 0.323 lbs/yr 1.32E-04 0.62 0.02
Hydrogen Chloride j 2.00 lbs/hr 1.19E-01 700 0.02
Formaldehyde 0 0464 lbs/hr 2.76E-01 150 0.18
Based on this modeling analysis, a limitation of 1.17 tons wood combusted per hour was placed into
the 02D .1100 toxics permit condition.
In 2017 the facility exceeded the hourly wood combustion limit. Review of modeling analysis
showed emission rates had not been optimized for allowable AALs. RCO AQAB agreed that
optimizing emission rates would have increased limits by factor of 5 or more.

8. Emissions Review
Overall emissions are expected to decrease due to this permit modification. The addition of one (1)
natural gas-fired boiler(16.739 mmBtu/hr maximum heat input), removing two of the four
steam-heated lumber drying kilns(62,000 board feet capacity each; from ID No. ES-2) and removing
two (2) steam-heated lumber drying kilns(62,000 board feet capacity each; ID No. ES-4)will
decrease Potential Emissions for PM(TSP), PMIo, PM2.5,NOx, CO and VOC.

from the NCDEQ Wood Waste Combustion Emissions Calculator Revision L 09/03/2019. Actual
yearly fuel usage is based on the combustion of 6,473 ton/yr of wood(the facility's total wood
combusted in 2021) in their wood-fired boiler(ID No. ES-1). The facility will only operate either the
natural gas-fired boiler or wood fired boiler,not both simultaneously. Potential VOC emissions from
the facility's wood kilns were derived from the NCDEQ Wood Kiln Emissions Calculator Revision C
July 2007. The potential bd-ft/year of steam heated kiln dried lumber was taken from the 2016
renewal dated 06/23/2016.
