(A)Buried,insulated in a manner that prevents access by a monitor probe,
(BB) Obstructed by equipment or piping that prevents access by a monitoring probe,
(C) Unable to be reached by a lift up to 25 feet above ground level,
(D)Inaccessible because it would require elevating the monitoring personnel more than seven feet
above a permanent support surface or would require the erection of scaffolding,or
(E) Not able to be accessed in a safe manner to perform monitoring;
(Connectors need not be individually identified if all connectors in a designated area or length of pipe
are identified as a group,and the number of connectors subject is indicated.)
ii. Pressure relief devices that are equipped with rupture disk upstream of the pressure device;
iii. Valves,pumps, and connectors that are designated unsafe-to-monitor(i.e.,Permittee has determined
that monitoring personnel would be exposed to an immediate danger as a consequence of complying
with the monitoring requirements); and
iv. Valves that are difficult-to-monitor(i.e.,Permittee has determined that the valve cannot be monitored
without elevating the monitoring personnel more than seven feet above a support surface or it is not
accessible in a safe manner when it is in regulated material service.
b. The Permittee shall record the identity of equipment designated as unsafe-to-monitor and/or difficult-to-
monitor and the planned schedule for monitoring this equipment, The Permittee shall include an
explanation why the equipment is unsafe or difficult-to-monitor.These records must be kept at the plant
and be available for review by an inspector.
i. The Permittee shall have a written plan that requires monitoring of the equipment as frequently as
practical during safe-to-monitor times,but not more frequently than the periodic monitoring schedule
otherwise applicable,and repair of the equipment if a leak is detected.
ii. The Permittee shall have a written plan that requires monitoring of difficult to monitor equipment at
least once per calendar year and repair of the equipment if a leak is detected.
c. Connectors that are designated as unsafe-to-repair will be repaired before the end of the next process unit

appendix A, except the instrument response factor criteria in section 3.1.2,paragraph(a) of Method
21 shall be for the representative composition of the process fluid not each individual VCC in the
stream. For process streams that contain nitrogen, air, water or other inerts that are not VQC, the
representative stream response factor shall be determined on an inert-free basis. The response factor
may he determined at any concentration for which monitoring for leaks will be conducted. If there is
no instrument commercially available that will meet the performance criteria specified above, the
instrument readings may be adjusted by multiplying by the representative response factor of the
process fluid,calculated on an inert-free basis.
iii. The detection instrument shall be calibrated annually by the manufacturer by the procedures specified
in Method 21 of 40 CFR part 60,appendix A.
iv. Calibration gases shall be zero air(less than 10 parts per million of hydrocarbon in air);and the gases

than the leak definition concentration of the equipment monitored. If the monitoring instrument's
design allows for multiple calibration scales,then the lower scale shall be calibrated with a calibration
gas that is no higher than 2,000 parts per million above the concentration specified as a leak, and the
highest scale shall be calibrated with a calibration gas that is approximately equal to 10,000 parts per
million. A calibration gas other than methane in air may be used if the instrument does not respond
to methane or if the instrument does not meet the performance criteria specified Method 21 of 40 CFR
part 60, appendix A. In such cases, the calibration gas may be a mixture of one or more of the
compounds to be measured in air.
v. Monitoring shall be performed when the equipment is in VQC service.
g. The Permittee may elect to adjust or not to adjust the instrument readings for background.
i. If the Permittee elects not to adjust instrument readings for background,the Permittee shall monitor
the equipment according to the procedures specified above in Section 2.2 B.2.f of this permit, above.
In such cases,all instrument readings shall be compared directly to the applicable leak definition for
the monitored equipment to determine whether there is a leak or to determine compliance with
operational standards for pressure relief devices.
ii. If the Permittee elects to adjust instrument readings for background,the Permittee shall
(A)Monitor the equipment according to the procedures specified above in Section 2.2 13.21,above;
(B) Determine the background level using the procedures in Method 21 of 40 CFR part 60,appendix
A;
(C) Traverse the potential leak interfaces with the instrument probe as close to the interface as
possible as described in Method 21 of 40 CFR part 60,appendix A;and
(D)Compare the arithmetic difference between the maximum concentration indicated by the
instrument and the background level to the applicable leak definition for the monitored equipment
to determine whether there is a leak or to determine compliance operational standards for pressure
relief devices.
h. When a leak is detected:
i. A weatherproof and readily visible identification, shall be attached to the leaking equipment,and
ii. Leak repair records shall be made that include the following:
(A)The date of first attempt to repair the leak;

time the leak is successfully repaired or determined to be non-repairable;
(D)Dates of process unit shutdowns that occur while the equipment is unrepaired; and
(E) Any delay of repair and the reason for the delay if a leak is not repaired within 15 calendar days
after discovery of the leak.
(1) The Permittee may develop a written procedure that identifies the conditions that justify a
delay of repair.The written procedures may be included as part of the startup,shutdown,and
malfunction plan, or may be part of a separate document that is maintained at the plant site.
Air Quality Permit No.01819T53
Page No.49
In such cases,reasons for delay of repair may be documented by citing the relevant sections
of the written procedure(i.e. season operation).
(2) If delay of repair was caused by depletion of stocked parts,there must be documentation that
the spare parts were sufficiently stocked on-site before depletion and the reason for depletion.
Leak Repair [15A NCAC 02Q .0508(f)]
i. The Permittee shall repair each leak detected as soon as practical,but not later than 15 calendar days after
it is detected,except as provided for in delay of repair and/or unsafe to repair connectors.A first attempt
at repair shall be made no later than 5 calendar days after the leak is detected. First attempt at repair for
pumps includes,but is not limited to,tightening the packing gland nuts and/or ensuring that the seal flush
is operating at design pressure and temperature. First attempt at repair for valves includes, but is not
limited to,tightening the bonnet bolts, and/or replacing the bonnet bolts, and/or tightening the packing
gland nuts, and/or injecting lubricant into the lubricated packing.
j. The leak identification on a valve in gas/vapor or light liquid service may be removed after it has been
monitored as specified in this permit and no leak has been detected during that monitoring, The leak
identification on a connector in gas/vapor or light liquid service may be removed after it has been
monitored as specified in this permit and no leak has been detected during that monitoring. Identification
that has been placed on equipment determined to have a leak, except for a valve or for a connector in
gas/vapor or light liquid service,may be removed after it is repaired.
k. Delay of repair is allowed for any of the conditions specified below.The Permittee shall maintain a record
of the facts that explain any delay of repairs and, where appropriate, why the repair was technically
infeasible without a process unit shutdown.
i. Delay of repair of equipment for which leaks have been detected is allowed if repair within 15 days
after a leak is detected is technically infeasible without a process unit or affected facility shutdown.
Repair of this equipment shall occur as soon as practical,but no later than the end of the next process
unit shutdown.However,delay of repair beyond a process unit shutdown will be allowed for a valve
if valve assembly replacement is necessary during the process unit shutdown, and valve assembly
supplies have been depleted, and valve assembly supplies had been sufficiently stocked before the
supplies were depleted.Delay of repair beyond the second process unit shutdown will not be allowed
unless the third process unit shutdown occurs sooner than six months after the first process unit
shutdown.
ii. Delay of repair of equipment for which leaks have been detected is allowed for equipment that is
isolated from the process and that does not remain in VOC service.
iii. Delay of repair for valves and connectors is also allowed if:
(A)The Permittee determines that emissions of purged material resulting from immediate repair
would be greater than the fugitive emissions likely to result from delay of repair,and
(B)When repair procedures are effected, the purged material cannot be collected and destroyed or
reused in the process.
iv. Delay of repair for pumps is also allowed if repair requires replacing the existing seal design with a
new system that the Permittee has determined under a quality improvement program (Sections 2,2
B,2.bb through 2.2 B.2.gg,below)will provide better performance,or the repair is completed as soon
as practical,but not later than b months after the leak was detected and one of the following is used;
(A)A dual mechanical seal system;
(B) A pump that meets has no external shaft penetrating the pump housing; or
(C) A system that routes emissions to a process or a fuel gas system or a closed vent system and
control device;

units,then the following provisions apply.
i. The overall performance of total valves in the group of process units to be subdivided shall be less
than two percent leaking valves.
ii. The initial assignment or subsequent reassignment of valves to subgroups sball be governed as
follows.
(A)The Permittee shall determine which valves are assigned to each subgroup.Valves with less than
one year of monitoring data or valves not monitored within the last twelve months must be placed
initially into the most frequently monitored subgroup until at least one year of monitoring data
have been obtained.
(B) Any valve or group of valves can be reassigned from a less frequently monitored subgroup to a
more frequently monitored subgroup provided that the valves to be reassigned were monitored
during the most recent monitoring period for the less frequently monitored subgroup. The
monitoring results must be included with that less frequently monitored subgroup's associated
percent leaking valves calculation for that monitoring event.
(C)Any valve or group of valves can be reassigned from a more frequently monitored subgroup to a
less frequently monitored subgroup provided that the valves to be reassigned have not leaked for
the period of the less frequently monitored subgroup (e.g., for the last 12 months, if the valve or
group of valves is to be reassigned to a subgroup being monitored annually). Note-repairable
valves may not be reassigned to a less frequently monitored subgroup.
iii. The Permittee shall determine every six months if the overall performance of total valves in the
applicable process unit or group of process units is less than two percent leaking valves and so indicate
the performance in the next periodic report.If the overall performance of total valves in the applicable
process unit or group of process units is two percent leaking valves or greater,the Permittee shall no
longer subgroup and shall revert to the program required in Section 2.2 B.2.p.for that group of process
units.The Permittee can again.elect to comply with the valve subgrouping procedures if future overall
performance of total valves in the process unit or group of process units is again less than two percent.

without elevating the monitoring personnel more than seven feet above a support surface or it is not
accessible in a safe manner when it is in regulated material service.
b. The Permittee shall record the identity of equipment designated as unsafe-to-monitor and/or difficult-to-
monitor and the planned schedule for monitoring this equipment, The Permittee shall include an
explanation why the equipment is unsafe or difficult-to-monitor.These records must be kept at the plant
and be available for review by an inspector.
i. The Permittee shall have a written plan that requires monitoring of the equipment as frequently as
practical during safe-to-monitor times,but not more frequently than the periodic monitoring schedule
otherwise applicable,and repair of the equipment if a leak is detected.
ii. The Permittee shall have a written plan that requires monitoring of difficult to monitor equipment at

appendix A, except the instrument response factor criteria in section 3.1.2,paragraph(a) of Method
21 shall be for the representative composition of the process fluid not each individual VCC in the
stream. For process streams that contain nitrogen, air, water or other inerts that are not VQC, the
representative stream response factor shall be determined on an inert-free basis. The response factor
may he determined at any concentration for which monitoring for leaks will be conducted. If there is
no instrument commercially available that will meet the performance criteria specified above, the
instrument readings may be adjusted by multiplying by the representative response factor of the
process fluid,calculated on an inert-free basis.
iii. The detection instrument shall be calibrated annually by the manufacturer by the procedures specified
in Method 21 of 40 CFR part 60,appendix A.
iv. Calibration gases shall be zero air(less than 10 parts per million of hydrocarbon in air);and the gases

to methane or if the instrument does not meet the performance criteria specified Method 21 of 40 CFR
part 60, appendix A. In such cases, the calibration gas may be a mixture of one or more of the
compounds to be measured in air.
v. Monitoring shall be performed when the equipment is in VQC service.
g. The Permittee may elect to adjust or not to adjust the instrument readings for background.
i. If the Permittee elects not to adjust instrument readings for background,the Permittee shall monitor
the equipment according to the procedures specified above in Section 2.2 B.2.f of this permit, above.
In such cases,all instrument readings shall be compared directly to the applicable leak definition for
the monitored equipment to determine whether there is a leak or to determine compliance with
operational standards for pressure relief devices.
ii. If the Permittee elects to adjust instrument readings for background,the Permittee shall
(A)Monitor the equipment according to the procedures specified above in Section 2.2 13.21,above;
(B) Determine the background level using the procedures in Method 21 of 40 CFR part 60,appendix
A;
(C) Traverse the potential leak interfaces with the instrument probe as close to the interface as
possible as described in Method 21 of 40 CFR part 60,appendix A;and
(D)Compare the arithmetic difference between the maximum concentration indicated by the
instrument and the background level to the applicable leak definition for the monitored equipment

(E) Any delay of repair and the reason for the delay if a leak is not repaired within 15 calendar days
after discovery of the leak.
(1) The Permittee may develop a written procedure that identifies the conditions that justify a
delay of repair.The written procedures may be included as part of the startup,shutdown,and
malfunction plan, or may be part of a separate document that is maintained at the plant site.
Air Quality Permit No.01819T53
Page No.49
In such cases,reasons for delay of repair may be documented by citing the relevant sections
of the written procedure(i.e. season operation).
(2) If delay of repair was caused by depletion of stocked parts,there must be documentation that
the spare parts were sufficiently stocked on-site before depletion and the reason for depletion.
Leak Repair [15A NCAC 02Q .0508(f)]
i. The Permittee shall repair each leak detected as soon as practical,but not later than 15 calendar days after
it is detected,except as provided for in delay of repair and/or unsafe to repair connectors.A first attempt
at repair shall be made no later than 5 calendar days after the leak is detected. First attempt at repair for
pumps includes,but is not limited to,tightening the packing gland nuts and/or ensuring that the seal flush
is operating at design pressure and temperature. First attempt at repair for valves includes, but is not
limited to,tightening the bonnet bolts, and/or replacing the bonnet bolts, and/or tightening the packing
gland nuts, and/or injecting lubricant into the lubricated packing.
j. The leak identification on a valve in gas/vapor or light liquid service may be removed after it has been
monitored as specified in this permit and no leak has been detected during that monitoring, The leak
identification on a connector in gas/vapor or light liquid service may be removed after it has been
monitored as specified in this permit and no leak has been detected during that monitoring. Identification
that has been placed on equipment determined to have a leak, except for a valve or for a connector in
gas/vapor or light liquid service,may be removed after it is repaired.
k. Delay of repair is allowed for any of the conditions specified below.The Permittee shall maintain a record
of the facts that explain any delay of repairs and, where appropriate, why the repair was technically
infeasible without a process unit shutdown.
i. Delay of repair of equipment for which leaks have been detected is allowed if repair within 15 days
after a leak is detected is technically infeasible without a process unit or affected facility shutdown.
Repair of this equipment shall occur as soon as practical,but no later than the end of the next process
unit shutdown.However,delay of repair beyond a process unit shutdown will be allowed for a valve
if valve assembly replacement is necessary during the process unit shutdown, and valve assembly
supplies have been depleted, and valve assembly supplies had been sufficiently stocked before the
supplies were depleted.Delay of repair beyond the second process unit shutdown will not be allowed
unless the third process unit shutdown occurs sooner than six months after the first process unit
shutdown.
ii. Delay of repair of equipment for which leaks have been detected is allowed for equipment that is
isolated from the process and that does not remain in VOC service.
iii. Delay of repair for valves and connectors is also allowed if:
(A)The Permittee determines that emissions of purged material resulting from immediate repair
would be greater than the fugitive emissions likely to result from delay of repair,and
(B)When repair procedures are effected, the purged material cannot be collected and destroyed or
reused in the process.
iv. Delay of repair for pumps is also allowed if repair requires replacing the existing seal design with a
new system that the Permittee has determined under a quality improvement program (Sections 2,2
B,2.bb through 2.2 B.2.gg,below)will provide better performance,or the repair is completed as soon
as practical,but not later than b months after the leak was detected and one of the following is used;
(A)A dual mechanical seal system;
(B) A pump that meets has no external shaft penetrating the pump housing; or
(C) A system that routes emissions to a process or a fuel gas system or a closed vent system and
control device;

i. The overall performance of total valves in the group of process units to be subdivided shall be less
than two percent leaking valves.
ii. The initial assignment or subsequent reassignment of valves to subgroups sball be governed as
follows.
(A)The Permittee shall determine which valves are assigned to each subgroup.Valves with less than
one year of monitoring data or valves not monitored within the last twelve months must be placed
initially into the most frequently monitored subgroup until at least one year of monitoring data
have been obtained.
(B) Any valve or group of valves can be reassigned from a less frequently monitored subgroup to a
more frequently monitored subgroup provided that the valves to be reassigned were monitored
during the most recent monitoring period for the less frequently monitored subgroup. The
monitoring results must be included with that less frequently monitored subgroup's associated
percent leaking valves calculation for that monitoring event.
(C)Any valve or group of valves can be reassigned from a more frequently monitored subgroup to a
less frequently monitored subgroup provided that the valves to be reassigned have not leaked for
the period of the less frequently monitored subgroup (e.g., for the last 12 months, if the valve or
group of valves is to be reassigned to a subgroup being monitored annually). Note-repairable
valves may not be reassigned to a less frequently monitored subgroup.
iii. The Permittee shall determine every six months if the overall performance of total valves in the
applicable process unit or group of process units is less than two percent leaking valves and so indicate
the performance in the next periodic report.If the overall performance of total valves in the applicable
process unit or group of process units is two percent leaking valves or greater,the Permittee shall no
longer subgroup and shall revert to the program required in Section 2.2 B.2.p.for that group of process
units.The Permittee can again.elect to comply with the valve subgrouping procedures if future overall
performance of total valves in the process unit or group of process units is again less than two percent.
The overall performance of total valves in the applicable process unit or group of process units shall
be calculated as a weighted average of the percent leaking valves of each subgroup according to
following equation:

next semiannual periodic report.
vi. The Permittee shall submit in the semiannual periodic reports the following information:
(A)Total number of valves in each subgroup,and
(B) The results of the semiannual overall performance calculation.
n. The Permittee perform percentage calculations for each process group(i.e.,botanical extraction,biomass
extraction, and Rotocellrecovery) for comparison with the sub grouping criteria specified in Section 2.2

VL = Number of valves found leaking, excluding non-repairable valves and including those
valves found whose repair was not confirmed with both post leak repair monitoring and
periodic monitoring.
VT = The sum of the total number of valves monitored.
o. When determining monitoring frequency for each process unit or valve subgroup subject to monthly,
quarterly,or semiannual monitoring frequencies,the percent leaking valves shall be the arithmetic average
of the percent leaking valves from the last two monitoring periods. When determining monitoring
frequency for each process unit or valve subgroup subject to annual or biennial (once every 2 years)
monitoring frequencies, the percent leaking valves shall be the arithmetic average of the percent leaking
valves from the last three monitoring periods.
i. Non-repairable valves shall he included in the calculation of percent leaking valves the first time the
valve is identified as leaking and non-repairable. Otherwise, a number of non-repairable valves
(identified and included in the percent leaking valves calculation in a previous period) up to a
maximum of one percent of the total number of valves in VOC service at a process unit may he
excluded from calculation of percent leaking valves for subsequent monitoring periods.
ii. If the number of non-repairable valves exceeds one percent of the total number of valves in regulated
material service at a process unit or affected facility,the number of non-repairable valves exceeding
one percent of the total number of valves in regulated material service shall be included in the
calculation of percent leaking valves.
p. If a leak is determined,then the leak shall be repaired. After a leak has been repaired,the valve shall be
monitored at least once within the first three months after its repair.
Air Quality Permit No. 01819'T53

i. This monitoring is in addition to the monitoring required to satisfy the definition of repaired and first
attempt at repair. The monitoring shall be conducted to determine whether the valve has resumed
leaking.
ii. Periodic monitoring may be used to satisfy this if the timing of the monitoring period coincides with
the time specified. Alternatively, other monitoring may be performed to satisfy the requirement
regardless of whether the timing of the monitoring period for periodic monitoring coincides with the
time above.
iii. If a leak is detected by monitoring that is conducted after leak repair,the Permittee shall:
(A)Use periodic monitoring to satisfy the requirement above, then the valve shall be counted as a
leaking valve,or
(B) If the Permittee elected to use other monitoring, prior to the periodic monitoring, to satisfy the
above requirement, then the valve shall be counted as a leaking valve unless it is repaired and
shown by periodic monitoring not to be leaking.
q. Any valve that is designated as an unsafe-to-monitor or difficult to monitor valve is exempt from the
requirements of Section 2.2 B.2.1,above,and the Permittee shall monitor the valve according to the written
plan specified in Section 2,2 B.2.b, above.

under the permit,due to unavoidable increases in emissions attributable to the emergency. An emergency
shall not include noncompliance to the extent caused by improperly designed equipment,lack of
preventive maintenance,careless or improper operation,or operator error.
2. An emergency constitutes an affirmative defense to an action brought for noncompliance with such
technology-based emission limitations if the conditions specified in 3.below are met.
3. The affirmative defense of emergency shall be demonstrated through properly signed contemporaneous
operating logs or other relevant evidence that include information as follows:
a. an emergency occurred and the Permittee can identify the cause(s)of the emergency;
b. the permitted facility was at the time being properly operated;
c. during the period of the emergency the Permittee took all reasonable steps to minimiTe levels of
emissions that exceeded the standards or other requirements in the permit; and
d. the Permittee submitted notice of the emergency to the DAQ within two working days of the time
when emission limitations were exceeded due to the emergency. This notice must contain a
description of the emergency,steps taken to mitigate emissions, and corrective actions taken.
