Dear Mr. Horton:
In accordance with your completed application received December•7, 2022, we are
forwarding herewith Permit No. 06650R14 to CertainTeed dba Millwork &Panel LLC, Claremont,
Catawba County,North Carolina for the construction and operation of air emissions sources or air
cleaning devices and appurtenances. Additionally, any emissions activities determined from your air
permit application as meeting the exemption requirements contained in 15A NCAC 2Q .0102 have
been listed for information purposes as an "ATTACHMENT" to the enclosed air permit.
If any parts, requirements, or limitations contained in this permit are unacceptable to you, '
you have the right to file a petition for contested case hearing in the North Carolina Office of
Administrative Hearings. Information regarding the right, procedure, and time limit for permittees
and other persons aggrieved to file such a petition is contained in the attached "Notice Regarding
the Right to Contest a Division of Air Quality Permit Decision."
Unless exempted by a condition of this permit or the regulations, construction of new
air pollution sources or air cleaning devices, or modifications to the sources or air cleaning
devices described in this permit must be covered under a permit issued by the Division of Air
Quality prior to construction. Failure to do so is a violation of G.S. 143-215.108 and may
subject the Permittee to civil or criminal penalties as described in G.S. 143-215.114A and 143-
215.114B.
This permit shall be effective from January 5, 2023 until December 31, 2030, is

Changes have been made to the permit stipulations. The Permittee is responsible for
carefully reading the entire permit and evaluating the requirements of each permit
stipulation.The Permittee shall comply with all terms, conditions, requirements, limitations
and restrictions set forth in this permit. Noncompliance with any permit condition is grounds
for enforcement action, for permit termination, revocation and reissuance, or modification, or
for denial of a permit renewal application. Specific changes and additions are summarized
below(note: this list may not include all changes and additions):
• A rule change that became effective November 1, 2016, removed the"state-wide"
applicability of 2D .0958, and it now only applies to the counties/townships listed in
the regulation. This facility is not located in one of the areas still subject to this -
regulation; therefore, the condition for 2D .0958 is being removed from the permit.
• Condition 15A NCAC 2D .1806 "Control.and Prohibition of Odorous Emissions"
was added to the permit per DAQ policy.
Should you have any questions concerning this matter, please contact Jennifer Manning at 704-235-

over a six-minute period, except that six-minute periods averaging not more than 87 percent
opacity may occur not more than once in any hour nor more than four times in any 24-hour
period. However, sources which must comply with a visible emissions standard in 15A
NCAC 2D .0524 "New Source Performance Standards" or .1110 "National Emission

iii. the time when the malfunction or breakdown is first observed,
iv. the expected duration, and
V. an estimated rate of emissions.
b. Notify the Director or his designee immediately when the corrective measures have
been accomplished.
This reporting requirement does not allow the operation of the facility in excess of
Environmental Management Commission Regulations.
6. FUGITIVE DUST CONTROL REQUIREMENT -As required by 15A NCAC 2D .0540
"Particulates from Fugitive Dust Emission Sources," the Permittee shall not cause or allow
fugitive dust emissions to cause or contribute to substantive complaints or excess visible
emissions beyond the property boundary. If substantive complaints are received or excessive

minutes in any one hour (using Reference Method 22 in 40 CFR, Appendix A), the owner or
operator may be required to submit a fugitive dust plan as described in 2D .0540(f).
"Fugitive dust emissions" means particulate matter that does not pass through a process
stack or vent and that is generated within plant property boundaries from activities such as:
unloading and loading areas, process areas stockpiles, stock pile working,plant parking lots,
and plant roads (including access roads and-haul roads).
7. CONTROL AND PROHIBITION OF ODOROUS EMISSIONS -As required by 15A
NCAC 2D .1806 "Control and Prohibition of Odorous Emissions" the Permittee shall not
