Dear Mr_Long:
In accordance with your completed Air Quality Pen-nit Application for a significant modification
under 15A NCAC 02Q .0501(b)(2)of a Title V permit received July 2, 2018,we are forwarding herewith
Air Quality Permit No.03 735T44 to Chemours Company—Fayetteville Works,Fayetteville,Bladen County,
North Carolina authorizing the construction and operation of the emission source(s) and associated air
pollution control device(s)specified herein. Additionally,any emissions activities determined from your Air
Quality Permit Application as being insignificant per 15A North Carolina Administrative Code 02Q .0503
have been listed for informational purposes. Please note the requirements for the annual compliance
certification are contained in General Condition P in Section 3.The current owner is responsible for submitting
a compliance certification for the entire year regardless of who owned the facility during the year.
As the designated responsible official,it is your responsibility to review,understand,and abide by all
of the terms and conditions of the attached permit. It is also your responsibility to ensure that any person who
operates any emission source and associated air pollution control device subject to any term or condition of
the attached permit reviews, understands, and abides by the condition(s) of the attached permit that are
applicable to that particular emission source.
If any parts,requirements,or limitations contained in this Air Quality Permit are unacceptable to you,
you have the right to request a formal adjudicatory hearing within 30 days following receipt of this permit,
identifying the specific issues to be contested. This hearing request must be in the form of a written petition,
conforming to NCGS (North Carolina General Statutes) 150B-23, and filed with both the Office of
Administrative Hearings,6714 Mail Service Center,Raleigh,North Carolina 27699-6714 and the Division of
Air Quality,Permitting Section, 1641 Mail Service Center,Raleigh,North Carolina 27699-1641. The form
for requesting a formal adjudicatory hearing may be obtained upon request from the Office of Adm in i strative
Hearings. Please note that this permit will be stayed in its entirety upon receipt of the request for a hearing.
Unless a request for a hearing is made pursuant to NCGS 15013-23, this Air Quality Permit shall be final and
binding 30 days after issuance.You may request modification of your Air Quality Permit through informal
means pursuant to NCGS 15013-22. This request must be submitted in writing to the Director and must

identify the specific provisions or issues for which the modification is sought. Please note that this Air Quality
Permit will become final and binding regardless of a request for informal modification unless a request for a
hearing is also made under NCGS 150B-23.
The construction of new air pollution emission source(s) and associated air pollution control
device(s), or modifications to the emission sources) and air pollution control device(s) described in this
permit must be covered under an Air Quality Permit issued by the Division of Air Quality prior to construction
unless the Permittee has fulfilled the requirements of NCGS 143-215.108A(b)and received written approval
from the Director of the Division of Air Quality to commence construction.Failure to receive an Air Quality
Permit or written approval prior to commencing construction is a violation of NCGS 143-215,108A and may
subject the Permittee to civil or criminal penalties as described in NCGS 143-215.114A and 143-215.114B.
Biaden County has triggered increment tracking under PSD for PMIo and SOz. This permit
modification will result in an increase of 0.17 pounds per hour of PMio and 0.0095 pounds per hour of SOz.
This Air Quality Permit shall be effective from March 14, 2019 until March 31, 2021, is
nontransferable to future owners and operators, and shall be subject to the conditions and limitations as
specified therein. Should you have any questions concerning this matter, please contact Heather Sands at

accordance with 15A NCAC 02D.2600 and follow the procedures outlined below:
1. The owner or operator of the source shall arrange for air emission testing protocols to be provided to the Director
prior to air pollution testing.Testing protocols are not required to be pre-approved by the Director prior to air
pollution testing.The Director shall review air emission testing protocols for pre-approval prior to testing if
requested by the owner or operator at least 45 days before conducting the test.
2. Any person proposing to conduct an emissions test to demonstrate compliance with an applicable standard shall
notify the Director at least 15 days before beginning the test so that the Director may at his option observe the test.

collection unless otherwise specified in the specific conditions. The owner or operator may request an extension to
submit the final test report.The Director shall approve an extension request if he finds that the extension request is a
result of actions beyond the control of the owner or operator.
a. The Director shall make the final determination regarding any testing procedure deviation and the validity of the
compliance test.The Director may:
i. Allow deviations from a method specified under a rule in this Section if the owner or operator of the source
being tested demonstrates to the satisfaction of the Director that the specified method is inappropriate for
the source being tested.
ii. Prescribe alternate test procedures on an individual basis when he finds that the alternative method is
necessary to secure more reliable test data.
iii. Prescribe or approve methods on an individual basis for sources or pollutants for which no test method is
specified in this Section if the methods can be demonstrated to determine compliance of permitted emission
sources or pollutants.
b. The Director may authorize the Division of Air Quality to conduct independent tests of any source subject to a
rule in this Subcbapter to determine the compliance status of that source or to verify any test data submitted
relating to that source.Any test conducted by the Division of Air Quality using the appropriate testing
procedures described in Section 02D.2600 has precedence over all other tests.
