In accordance with your completed Air Quality Permit Application for an Administrative
Amendment/Name Change of your Title V permit, we are forwarding herewith Air Quality Permit No.
04319T27 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(8) have
been identified as such in the permit. Please note the requirements for the annual compliance certification
are contained in General Condition P in Section 4. 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 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.”

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.

Permit 02977T27
Page 41

the ambient air quality standards or are required to create an offset, the permit shall contain a condition requiring these
controls.

JJ. General Emissions Testing and Reporting Requirements [15A NCAC 02Q .0508(i)(16)]
Emission compliance testing shall be by the procedures of Section .2600, except as may be otherwise required in Rules
.0524, .1110, or .1111 of Subchapter 02D. If emissions testing is required by this permit or the DAQ or if the Permittee
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.
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]
1. A permit shall be reopened and revised under the following circumstances:
a. additional applicable requirements become applicable to a facility with remaining permit term of three or more
years;
b. additional requirements (including excess emission requirements) become applicable to a source covered by Title
IV;
c. the Director or EPA finds that the permit contains a material mistake or that inaccurate statements were made in
establishing the emissions standards or other terms or conditions of the permit; or
d. the Director or EPA determines that the permit must be revised or revoked to assure compliance with the
applicable requirements.
2. Any permit reopening shall be completed or a revised permit issued within 18 months after the applicable requirement
is promulgated. No reopening is required if the effective date of the requirement is after the expiration of the permit
term unless the term of the permit was extended pursuant to 15A NCAC 02Q .0513(c).
3. Except for the state-enforceable only portion of the permit, the procedures set out in 15A NCAC 02Q .0507, .0521, or
.0522 shall be followed to reissue the permit. If the State-enforceable only portion of the permit is reopened, the
procedures in 15A NCAC 02Q .0300 shall be followed. The proceedings shall affect only those parts of the permit for
which cause to reopen exists.
Permit 02977T27
Page 42

4. The Director shall notify the Permittee at least 60 days in advance of the date that the permit is to be reopened, except
in cases of imminent threat to public health or safety the notification period may be less than 60 days.
5. Within 90 days, or 180 days if the EPA extends the response period, after receiving notification from the EPA that a
permit needs to be terminated, modified, or revoked and reissued, the Director shall send to the EPA a proposed
determination of termination, modification, or revocation and reissuance, as appropriate.

LL. Reporting Requirements for Non-Operating Equipment [15A NCAC 02Q .0508(i)(16)]
The Permittee shall maintain a record of operation for permitted equipment noting whenever the equipment is taken from
and placed into operation. When permitted equipment is not in operation, the requirements for testing, monitoring, and
recordkeeping are suspended until operation resumes.

MM. Fugitive Dust Control Requirement [15A NCAC 02D .0540]
As required by 15A NCAC 02D .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 or excessive fugitive dust emissions from the facility are observed beyond the
property boundaries for six 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 02D .0540(f).

"Fugitive dust emissions" means particulate matter from process operations 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).

NN. Specific Permit Modifications [15A NCAC 02Q .0501 and .0523]
1. For modifications made pursuant to 15A NCAC 02Q .0501(b)(2), the Permittee shall file a Title V Air Quality Permit
Application for the air emission source(s) and associated air pollution control device(s) on or before 12 months after
commencing operation.
2. For modifications made pursuant to 15A NCAC 02Q .0501(c)(2), the Permittee shall not begin operation of the air
emission source(s) and associated air pollution control device(s) until a Title V Air Quality Permit Application is
filed and a construction and operation permit following the procedures of Section .0500 (except for Rule .0504 of
this Section) is obtained.
3. For modifications made pursuant to 502(b)(10), in accordance with 15A NCAC 02Q .0523(a)(1)(C), the Permittee
shall notify the Director and EPA (Air Permitting Branch, EPA, Region 4, 61 Forsyth Street SW, Atlanta, GA 30303
or through the EPA CEDRI) in writing at least seven days before the change is made.
a. The written notification shall include:
i. a description of the change at the facility;
ii. the date on which the change will occur;
iii. any change in emissions; and
iv. any permit term or condition that is no longer applicable as a result of the change.
b. In addition to this notification requirement, with the next significant modification or Air Quality Permit
renewal, the Permittee shall submit a page "E5" of the application forms signed by the responsible official
verifying that the application for the 502(b)(10) change/modification, is true, accurate, and complete. Further
note that modifications made pursuant to 502(b)(10) do not relieve the Permittee from satisfying
preconstruction requirements.

OO. Third Party Participation and EPA Review [15A NCAC 02Q .0521, .0522 and .0525(7)]
For permits modifications subject to 45-day review by the federal EPA, EPA’s decision to not object to the proposed
permit is considered final and binding on the EPA and absent a third party petition, the failure to object is the end of
EPA's decision-making process with respect to the revisions to the permit. The time period available to submit a public
petition pursuant to 15A NCAC 02Q .0518 begins at the end of the 45-day EPA review period.
