The construction of new air pollution emission source(s)and associated air pollution control device(s),
or modifications to existing emission source(s)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.
Chatham County has triggered increment tracking under PSD for NOx,PMIo and SOz. However,this
permit modification does not consume or expand increments for any pollutants.
This Air Quality Permit shall be effective from January 13,2022 and shall expire on the earlier of
August 31,2026 or the renewal of Permit No. 09006T06 has been issued or denied. This Air Quality Permit
is nontransferable to future owners and operators, and shall be subject to the conditions and limitations as
specified therein.

submits emissions testing to the DAQ to demonstrate compliance for emission sources subject to Rules.0524, .1110,or
.1111,the Permittee shall provide and submit all notifications,conduct all testing,and submit all test reports in
accordance with the requirements of 15A NCAC 02D.0524,.1110,or.1111,as applicable. Otherwise,if emissions
testing is required by this permit or the DAQ or if the Permittee submits emissions testing to the DAQ to demonstrate
compliance,the Permittee shall perform such testing in 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.
3. The owner or operator of the source shall arrange for controlling and measuring the production rates during the
period of air testing.The owner or operator of the source shall ensure that the equipment or process being tested is
operated at the production rate that best fulfills the purpose of the test. The individual conducting the emission test
shall describe the procedures used to obtain accurate process data and include in the test report the average
production rates determined during each testing period.
4. Two copies of the final air emission test report shall be submitted to the Director not later than 30 days after
sample 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 15A NCAC 02D .2600 if the methods can be demonstrated to determine compliance of
permitted emission sources or pollutants.

Permit No. 09006T08
Page 44
b. The Director may authorize the DAQ to conduct independent tests of any source subject to a rule in 15A
NCAC 02D 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 15A NCAC 02D .2600 has precedence over all other tests.
KK. Reopening for Cause[15A NCAC 02Q.0517]
