No. 2 fuel oil for one natural gas-fired/No. 2 fuel oil-fired boiler(ID No. ES-B5)at Plant
No. 1. The No. 2 fuel oil aboveground storage tank(10,000 gallon maximum capacity)is
exempt per 15A NCAC 2Q .0102 (g)(4). This tank should be listed in the insignificant/
exempt activities of the air permit during the next revision.
This tank is listed in item 9. of this report for permit changes and also placed on the
yellowsheet in the facility's electronic file.
b. This company has one corrugator that is used to corrugate the fiber sheets,bind the fiber
sheets together using glue(corn starch/water/borax/caustic mixture), dry the corrugated
fiber sheets using steam from the two NSPS affected boilers(ID Nos. ES-B3 or#2 and
ES-B4 or#1) at Plant No. 2, and cut excessive trim from the fiber sheets. The corrugator
has no exhaust to the outside atmosphere. During the inspection,the corrugator at Plant
No. 2 was in operation.
At Plant No. 2,the trim from the fiber sheets is picked up from flexible steel pickup lines
on the trim pipe of the corrugator and then transported to an air separator. From the air
separator,the trim is transported to the baler and then baled. Any scrap paper from two
shredders ("hoggers"; referred to as wet end and dry end by this company)and one
pickup vent on the floor are transported via separate fans to the air separator. From the
air separator,the shredded scrap paper is transported to the baler and then baled. The
bales of shredded paper are sent to a paper mill to be recycled.
Any particulate matter emissions from the air separator are transported to a metal box and
then into the filter system(cloth on the outside of the filter; size unknown). From the
filter system, any dust waste exhausts to a closed-loop cyclone and then through a rotary
valve into a metal box located underneath this cyclone. From the metal box,the dust
waste is compressed by a machine into oval brick forms ("pucks"). The oval brick forms
("pucks")are dropped into an open bin and then transported to a landfill. The air from the
cyclone is returned back to the metal box prior to the filter system.
The filter system, closed-loop cyclone,oval brick machine, air separator and baler
exhausts inside of the building at Plant No. 1. During the inspection,the air separator,
two shredders("hoggers"),baler, filter system,closed-loop cyclone,pickup vent on the
floor and oval brick machine were in operation. I observed no visible emissions from
these sources during the inspection.

Observed. On January 21,2021,this office received the annual actual emissions
reports for 2020 calendar year 2020 from this company. This company reported
that 408 gallons of No. 2 fuel oil was combusted in the boilers(ID No. ES-B3,
ES-B4 and ES-B5) for periodic testing in 2020 calendar year. The facility-wide
S02 emissions from the combustion of natural gas and No. 2 fuel oil in the three
boilers were 0.019 tons during 2020 calendar year. Compliance with this
stipulation is indicated.
k. Condition A. 12. Avoidance Condition for Area Sources Subject to 40 CFR 63 Subpart
JJJJJJ 61 -In accordance with 15A NCAC 2Q .0317,the permittee is avoiding

Greif Packaging,LLC—CorrChoice Concord
January 28,2021
Page 14
applicability of 40 CFR 63 Subpart JJJJJJ(6J) "Industrial, Commercial,and Institutional
Boilers Area Sources." The permittee is permitted to operate a natural gas/No. 2 fuel oil-
fired boilers (ID Nos. ES-133,ES-134 and ES-135). Per 40 CFR 63.11195(e),these
sources are exempt from this subpart because they are defined as gas-fired boiler in 40
CFR 63.11237. In order to maintain this exemption,the permittee is allowed to fire
liquid fuel only during periods of gas curtailment,gas supply interruptions, startups, or
for periodic testing on liquid fuel(periodic testing not to exceed a combined total of 48
hours during any calendar year).
i. The permittee shall maintain records that document the time periods when liquid
fuel is fired and reasons the liquid fuel is fired.
ii. If the permittee fires liquid fuel for reasons other than gas curtailment, gas supply
interruptions, startups, or for periodic testing on liquid fuel,the Permittee is no
longer exempt from Subpart JJJJJJ(6J). As required by 40 CFR 62.11225(g),the
Permittee must provide notice within 30 days of the fuel switch. The notification
must identify:
A. The name of the owner or operator of the affected source,the location of
the source,the boiler(s)that have switched fuels, and the date of the
notice.
B. The date upon which the fuel switch occurred.
C. As required by 40 CFR 63.11210(h),the permittee must demonstrate
compliance within 180 days of the effective date of the fuel switch.
Observed. NCDAQ received the initial notification form from this facility on September
13,2011, stating that the existing boilers (ID Nos. ES-133 and ES-134; considered existing
if constructed before June 4,2010)combusts natural gas and only uses No. 2 fuel oil as a
back-up during periods of gas curtailment,gas supply interruptions, startups, and for
periodic testing(not to exceed a combined total of 48 hours for each boiler during any
calendar year).
The boiler(ID No. ES-135)is considered a new area source per NESHAP area boiler
GACT Subpart JJJJJJ(6J), since it commenced construction after June 4, 2010. During
the permitting process of this boiler(ID No. ES-135),this company chose to avoid
NESHAP Subpart 6J boiler GACT by only burning No .2 fuel oil during times of
curtailment, emergencies and periodic testing. The startup of this boiler firing No. 2 fuel
oil occurred on July 26,2016.
No curtailment or supply interruption of natural gas to the three boilers(ID Nos. ES-133,
ES-B4 and ES-B5) occurred during 2020 calendar year to present date. The periodic
testing of each boiler on No. 2 fuel oil is conducted for 30 minutes once a month. The
periodic testing of the three boilers on No. 2 fuel oil was each less than 48 hours from
2020 calendar year to present date.
Therefore,the three boilers (ID Nos. ES-133,ES-134 and ES-135)burning only natural gas
are not subject to the National Emission Standards for Hazardous Air Pollutants
(NESHAP)for Industrial, Commercial, and Institutional Boilers Area Sources(40 CFR

Greif Packaging,LLC—CorrChoice Concord

Part 63, Subpart JJJJJJ or 6J). Compliance with this stipulation is indicated.
1. Condition A. 13. Toxic Air Pollutant Emissions Limitation Requirement-Pursuant to
15A NCAC 2Q .0711 "Emission Rates Requiring a Permit" for each of the below listed
toxic air pollutants (TAPS),the permittee has made a demonstration that facility-wide
actual emissions,where one or more emission release points are obstructed or non-
vertically oriented, do not exceed the Toxic Permit Emission Rates(TPERs) listed in 15A
NCAC 2Q .0711(a). The facility shall be operated and maintained in such a manner that
emissions of any listed TAPs from the facility, including fugitive emissions,will not
exceed TPERs listed in 15A NCAC 2Q .0711(a).

Observed. The TPER limits of 2Q .0711(a) are applicable since the exhaust stacks of the
three boilers are a mixture of vertical and capped and uncapped. This company operates
this facility 24 hours per day, 5 days per week and 52 weeks per year. The primary fuel
of the three boilers (ID Nos. ES-133,ES-134 and Es-135) is natural gas. No. 2 fuel oil is
combusted if the three boilers are curtailed or periodic testing.
This company is tracking the monthly natural gas and No. 2 fuel oil usage in an
electronic Excel spreadsheet. The facility-wide natural gas usage was 134,525 ccf in
calendar year 2020. The No. 2 fuel oil usage was 408 gallons in calendar year 2020.
The DAQ combustion emissions calculator spreadsheets for natural gas and No. 2 fuel oil
were used to determine if the above listed pollutants were being exceeded. The actual
emissions from the combustion of natural gas and No.2 fuel oil in the three boilers
during calendar year 2020 indicate that each pollutant is less than the respective TPER
limits listed in the above table. Compliance with this stipulation is indicated.
8. NSPS/NESHAP Review:
a. The three boilers(ID Nos. ES-133,ES-134 and ES-135)burning only natural gas are not
subject to the National Emission Standards for Hazardous Air Pollutants(NESHAP) for
Industrial, Commercial, and Institutional Boilers Area Sources (40 CFR Part 63, Subpart
JJJJJJ or 6J). This company will only burn No. 2 fuel oil in the three boilers(ID Nos.
ES-133,ES-134 and ES-135) during times of gas curtailment,gas supply interruptions,
startups, or for periodic testing(not to exceed combined total of 48 hours per boiler
during any calendar year) (refer to explanation in Specific Condition and Limitation No.
A. 12).
b. The three boilers (ID Nos.ES-133,ES-134 and ES-135) are subject to 40 CFR Part 60,
Subpart Dc-"Standards of Performance for Small-Industrial-Commercial-Institutional
Steam Generating Units," since these boilers were constructed after June 9, 1989 with a
maximum heat input capacity greater than 10 million Btu per hour(refer to explanation in
Specific Condition and Limitation No. A. 7.).
C. This company has no emergency or peak shaving engines/generators or gasoline storage

tanks at this facility. The fire pump at Plant No. 2 is not subject to NESHAP Subpart 4Z,
since it is electrically powered.
9. Summary of changes needed to the current permit:
a. The No. 2 fuel oil aboveground storage tank (10,000 gallon maximum capacity) should
be listed in the insignificant/exempt activities in permit attachment during the next
revision. The No. 2 fuel oil tank is exempt per 15A NCAC 2Q .0102 (g)(4).
b. The electronic yellowsheet for permit changes needed has been completed and placed in
the facility's electronic file.
10. Compliance assistance offered duringthe h�pection:
Air Permit No. 06503R12 will expire on September 30, 2021. Specific Condition and Limitation
No. A. 2. "Permit Renewal and Emission Inventory Requirement" states that the permittee request
permit renewal by letter along with an application form and submit air pollution emissions
inventory report for the 2020 calendar year with certification sheet at least ninety (90) days prior
to the expiration date of the permit. I discussed the permit renewal requirements with Mr. Wilson
and Mr. Hogle.
11. Section 112(r)applicability:
This facility does not appear to be subject to the requirements of the Chemical Accident Release
Prevention Program, Section 112(r)of the Clean Air Act.
12. Compliance determination:
Based on my observations, this facility appeared to be in compliance with the applicable air
quality regulations at the time of the inspection.
