Required Annual Point Source Air Pollutant Emissions Inventory for Calendar Year 2022
Unilin Flooring NC, LLC - Thomasville Facility
Air Quality Permit No. 09481T17
Facility ID: 2900346, Thomasville, Davidson County
SUBJECT:
Dear Mr. Stofferis:
All Title V facilities, and others receiving this notice, are required to provide a point source air emissions
inventory, quantifying actual air pollutant emissions for calendar year (CY) 2022, under the authority of Title
15A NCAC 2Q.0207 and 2D.0202, and as a condition of the operating permit. Your facility data will be
available in Air Emissions Reporting Online (AERO) on February 15, 2023. You must complete and
submit the report even if: 1) your facility has been modified recently such that the permit classification has
changed, 2) you anticipate such changes, or 3) your facility did not operate in CY 2022.
Please note that reporting of estimates of greenhouse gases to NC Division of Air Quality (DAQ) for CY
2022 is voluntary. Greenhouse gases are included in the DAQ pollutant list. Guidance on estimating these
emissions can be found on NC DAQ's webpage, https://deq.nc.gov/media/7502/download.
The DAQ's Internet-based reporting tool, AERO, may be accessed at https://xapps.ncdenr.org/aq/aero/.
AERO may also be accessed on the DAQ webpage by scrolling down the page to the AERO quicklink or
selecting the "Emissions Inventory" Program link. You will need to use your unique User Id: and PIN: when
you logon to AERO. This process protects the information so that only you or your authorized representative
(and assigned DAQ staff) may access, view, and update the information. It is your responsibility to control the
use of this unique PIN. Beginning with CY2020, the emission estimation code list has been expanded to be
consistent with US EPA’s emission estimation code list. The US EPA has made significant changes to how
controls are reported to their emission inventory system. Please note the EPA's TANKS program is outdated
and should no longer be used to estimate emissions from storage tanks. If you have any questions about
emission estimation codes, controls or the TANKS program, please consult your regional office.

You may make updates to your data from the previous year and submit the data online through AERO. If
there are significant changes in emission values, it would be helpful to the DAQ reviewer if you would include
comments noting the reason(s) for the differences. Prior to adding emission sources through AERO, it may be
beneficial to contact the appropriate regional office to discuss the necessity of including these sources. You
are reminded that the CY 2021 emissions data for sources included in the Insignificant Activities list attached

to your permit can be carried forward to CY 2022 if no significant emission changes have occurred.
Pre-filled, site-specific forms for your facility are also available to print from AERO, but we highly encourage
use of the online capabilities for data submittal. If you do not have access to a computer or to the Internet,
please contact Dylan Wright of the DAQ Winston-Salem Regional Office at 336-776-9800 to request
assistance.
When updating online, you must complete the "submit" process in AERO, and provide a paper
Certification Form with the submittal date and time stamp at the top of the form (signed by the legally
responsible official in blue ink) along with the supporting documentation and emission calculations to the
appropriate regional office. The facility is responsible for ensuring that the AERO (electronic) submittal is
completed and that all forms and supporting documentation are mailed (postmarked) by June 30, 2023 to the
address below.
Furthermore, if you are requesting information to be held as confidential, you must submit written
justification as to how the information you have marked confidential should be held as such. This request must
include the following:
a. How the information meets the definition of "Trade Secret" per NCGS 132-1.2 and NCGS 66-152(3);
b. How the information is not "Emissions Data" as defined in 40 CFR 2.301;
c. How your facility would be affected if the information is disclosed; and
d. How the information is protected at your facility.
If you choose to submit via paper forms, you must submit one complete original packet including an
Emission Source/Operating Scenario form for each emission source or emission source group, a signed
Certification form, supporting documentation and emission calculations; postmarked no later than June 30, 2023
to:
Air Emissions Inventory
Winston-Salem Regional Office
450 West Hanes Mill Road
Suite 300
Winston-Salem, NC 27105
Incomplete submittals will not be accepted. Extensions are not normally granted. Facsimiles (faxes) or
e-mails will not be accepted as an original submittal. Sources failing to comply by the stated deadline may be
subject to enforcement action. If submitting paper forms or the certification form that includes the submittal
date and time stamp with supporting documentation and calculations via US mail or a private carrier, we
strongly urge that you use certified or tracked mail, so you have a record should there be any question or
dispute regarding its timely receipt.
Sincerely,
Original signed with Director electronic signature
