d. Instrument monitoring shall be conducted for
i. Valves in gas/vapor or light liquid service;
ii. Pumps in light liquid service;
iii. Connectors in gas/vapor or light liquid service; and
iv. Pressure relief devices in gas/vapor service.
e. Sensory monitoring for leaks shall be conducted for pumps in light liquid service. Sensory monitoring
consists of visual, audible, olfactory, or any other detection method used to determine a potential leak to
the atmosphere.
f. Instrument monitoring shall comply with the following requirements,
i. Monitoring shall comply with Method 21 of 40 CFR part 60, appendix A.
ii. The detection instrument shall meet the performance criteria of Method 21 of 40 CFR part 60,
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 VOC in the
stream. For process streams that contain nitrogen, air, water or other inerts that are not VOC, the
representative stream response factor shall be determined on an inert-free basis. The response factor
may be 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
shall be mixtures of methane in air at a concentration no more than 2,000 parts per million greater
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 VOC 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 B.2.f, 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:

Permit 01819T46
Page 37
(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.
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 6 months after the leak was detected and one of the following is used;

shall monitor each valve once per month.
ii At process units with less than the greater of two leaking valves or two percent leaking valves, the
Permittee shall monitor each valve once each quarter,except as provided below.
(A)The Permittee may elect to monitor each valve once every two quarters for process units with less
than one percent leaking valves.
(B) The Permittee may elect to monitor each valve once every four quarters for process units with
less than 0.5 percent leaking valves.
(C) The Permittee may elect to monitor each valve once every two years for process units with less
than 0.25 percent leaking valves.
iii. The Permittee shall keep a record of the monitoring schedule for each process unit.
in. The Permittee may choose to subdivide the valves in the group of process units and apply the monitoring
frequency provisions to each subgroup. If the Permittee subdivides the valves in the group of process
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 shall 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). Non-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:

i=1
Where: %VLp= Overall performance of total valves in the applicable process unit or group of process
units
%VLi =Percent leaking valves in subgroup i, most recent value
Vi =Number of valves in subgroup i
n =Number of subgroups.

(C) Which valves are reassigned,the last monitoring result prior to reassignment,and when they were
reassigned; and
(D)The results of the semiannual overall performance calculation.
v. The Permittee shall notify the DAQ no later than 30 days prior to the beginning of the next monitoring
period of the decision to subgroup valves. The notification shall identify the participating process
units and the number of valves assigned to each subgroup, if applicable, and may be included in the
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 Rotocel/recovery) for comparison with the sub grouping criteria specified in Section 2.2
B.2.m, above, and the percent leaking valves for each monitoring period for each process unit or valve
subgroup shall be calculated using the following equation:
%VL = VL X 100
T
Where: %VL = Percent leaking valves.
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 be 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 be
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

Permit 01819T46
Page 40
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.
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.

designated as an unsafe-to-monitor pump is exempt from this requirement and shall be monitored and
inspected according to the written plan specified in Section 2.2 B.2.b, above.
s. Each pump shall be checked by visual inspection each calendar week for indications of liquids dripping
from the pump seal. The Permittee shall document that the inspection was conducted and the date of the
inspection. If there are indications of liquids dripping from the pump seal at the time of the weekly
inspection, the Permittee shall:
i. Monitor the pump as specified in this permit and if the instrument reading indicates a reading of 2,000
parts per million (ppm) or greater it shall be repaired using the procedures in Sections 2.2 B.2.i
through 2.2 13.21, above; or
ii. Eliminate the visual indications of liquids dripping.
Any pump that is located within the boundary of an unmanned plant site is exempt from the weekly visual
inspection provided that each pump is visually inspected as often as practical and at least monthly.
t. If, when calculated on a 6-month rolling average for the percent leaking pumps, at least the greater of
either 10 percent of the pumps in a process unit or three pumps in a process unit leak, the Permittee shall
implement a quality improvement program for pumps Sections 2.2.B.2.bb through 2.2 B.2.gg,below.The
Permittee shall not alter the process grouping used in calculating this percentage.
i. The number of pumps at a process unit shall be the sum of all the pumps in VOC service, except that
pumps found leaking in a continuous process unit within one month after start-up of the pump shall
not count in the percent leaking pumps calculation for that one monitoring period only.
ii. Percent leaking pumps shall be determined by the following equation:

background,and
iii. The Pennittee shall record the dates and results of the monitoring following a pressure release
including the background level measured and the maximum instrument reading measured during the
monitoring.
aa. Any pressure relief device that is equipped with a rupture disk upstream of the pressure relief device is
exempt from monitoring provided the Pennittee installs a replacement rupture disk upstream of the
pressure relief device as soon as practical after each pressure release but no later than five calendar days
after each pressure release,except as provided for in delay of repair.
Quality improvement program for pumps [15A NCAC 02Q .0508(f)]
bb. If,on a 6-month rolling average,at least the greater of either 10 percent of the pumps in a process unit or
three pumps in a process unit leak, the Pennittee shall implement a quality improvement plan until the

i. The analysis shall also be used to determine if there are superior performing pump or pump seal
technologies that are applicable to the service(s),operating conditions,or pump or pump seal designs
associated with poorer than average emission performance.A superior performing pump or pump seal
technology is one with a leak frequency of less than 10 percent for specific applications in the process
unit.A candidate superior performing pump or pump seal technology is one demonstrated or reported
in the available literature or through a group study as having low emission performance and as being
capable of achieving less than 10 percent leaking pumps in the process unit.
ii. The analysis shall include consideration of the following information:
(A) The data obtained from the inspections of pumps and pump seals removed from the process unit
due to leaks;
(B) Information from the available literature and from the experience of other plant sites that will
identify pump designs or technologies and operating conditions associated with low emission
performance for specific services; and
(C) Information on limitations on the service conditions for the pump seal technology operating
conditions as well as information on maintenance procedures to ensure continued low emission
performance.

the quality improvement program.
ff. The Permittee shall prepare and implement a pump quality assurance program that details purchasing
specifications and maintenance procedures for all pumps and pump seals in the process unit. The quality
assurance program may establish any number of categories, or classes, of pumps as needed to distinguish
among operating conditions and services associated with poorer than average emission performance as
well as those associated with better than average emission performance. The quality assurance program
shall be developed considering the findings of the data analysis required under paragraph Section
2.2B.2.ee,above,and the operating conditions in the process unit.The quality assurance program shall be
updated each year as long as the process unit has the greater of either 10 percent or more leaking pumps
or has three leaking pumps.

(A)Establish minimum design standards for each category of pumps or pump seal technology. The
design standards shall specify known critical parameters such as tolerance, manufacturer,
materials of construction,previous usage, or other applicable identified critical parameters.
(B) Require that all equipment orders specify the design standard (or minimum tolerances) for the
pump or the pump seal.
(C) Provide for an audit procedure for quality control of purchased equipment to ensure conformance
with purchase specifications.
(D)Detail off-line pump maintenance and repair procedures. These procedures shall include
provisions to ensure that rebuilt or refurbished pumps and pump seals will meet the design
specifications for the pump category and will operate so that emissions are minimized.
ii. The quality assurance program shall be established no later than the start of the third year of the
quality improvement program.

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.

Instrument and sensory monitoring for leaks [15A NCAC 02Q .0508(f)]
d. Instrument monitoring shall be conducted for
i. Valves in gas/vapor or light liquid service;
ii. Pumps in light liquid service;
iii. Connectors in gas/vapor or light liquid service; and
iv. Pressure relief devices in gas/vapor service.
e. Sensory monitoring for leaks shall be conducted for pumps in light liquid service. Sensory monitoring
consists of visual, audible, olfactory, or any other detection method used to determine a potential leak to
the atmosphere.
f. Instrument monitoring shall comply with the following requirements,
i. Monitoring shall comply with Method 21 of 40 CFR part 60, appendix A.
ii. The detection instrument shall meet the performance criteria of Method 21 of 40 CFR part 60,
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 VOC in the
stream. For process streams that contain nitrogen, air, water or other inerts that are not VOC, the
representative stream response factor shall be determined on an inert-free basis. The response factor
may be 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
shall be mixtures of methane in air at a concentration no more than 2,000 parts per million greater
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 VOC 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 B.2.f, 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:

Permit 01819T46
Page 37
(A)The date of first attempt to repair the leak;
(B) The date of successful repair of the leak;
(C) The maximum instrument reading measured by Method 21 of 40 CFR part 60,appendix A at the
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.
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

Valves in GasNapor/Light Liquid Service [15A NCAC 02Q .0508(f)]
1. The Permittee shall monitor all valves using the method specified in this permit at the intervals, except
unsafe to monitor valves and maintain records as specified below. The instrument reading that defines a
leak is 500 parts per million or greater.
i. If at least the greater of two valves or two percent of the valves in a process unit leak, the Permittee
shall monitor each valve once per month.
ii At process units with less than the greater of two leaking valves or two percent leaking valves, the
Permittee shall monitor each valve once each quarter,except as provided below.
(A)The Permittee may elect to monitor each valve once every two quarters for process units with less
than one percent leaking valves.
(B) The Permittee may elect to monitor each valve once every four quarters for process units with
less than 0.5 percent leaking valves.
(C) The Permittee may elect to monitor each valve once every two years for process units with less
than 0.25 percent leaking valves.
iii. The Permittee shall keep a record of the monitoring schedule for each process unit.
in. The Permittee may choose to subdivide the valves in the group of process units and apply the monitoring
frequency provisions to each subgroup. If the Permittee subdivides the valves in the group of process
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 shall 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). Non-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:

Permit01819T46

i=1
Where: %VLp= Overall performance of total valves in the applicable process unit or group of process
units
%VLi =Percent leaking valves in subgroup i, most recent value
Vi =Number of valves in subgroup i
n =Number of subgroups.
iv. The Permittee shall maintain the following records:
(A) Which valves are assigned to each subgroup;
(B) Monitoring results and calculations made for each subgroup for each monitoring period;
(C) Which valves are reassigned,the last monitoring result prior to reassignment,and when they were
reassigned; and
(D)The results of the semiannual overall performance calculation.
v. The Permittee shall notify the DAQ no later than 30 days prior to the beginning of the next monitoring
period of the decision to subgroup valves. The notification shall identify the participating process
units and the number of valves assigned to each subgroup, if applicable, and may be included in the
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 Rotocel/recovery) for comparison with the sub grouping criteria specified in Section 2.2
B.2.m, above, and the percent leaking valves for each monitoring period for each process unit or valve
subgroup shall be calculated using the following equation:
%VL = VL X 100
T
Where: %VL = Percent leaking valves.
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 be 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 be
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

Permit 01819T46
Page 40
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.
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.
Pumps in light liquid service standards [15A NCAC 02Q .0508(f)]
r. The pumps shall be instrumentally monitored monthly to detect leaks by the method specified in this
permit. The instrument reading that defines a leak is 1,000 parts per million or greater. Repair is not
required unless an instrument reading of 2,000 parts per million or greater is detected. Any pump that is
designated as an unsafe-to-monitor pump is exempt from this requirement and shall be monitored and
inspected according to the written plan specified in Section 2.2 B.2.b, above.
s. Each pump shall be checked by visual inspection each calendar week for indications of liquids dripping
from the pump seal. The Permittee shall document that the inspection was conducted and the date of the
inspection. If there are indications of liquids dripping from the pump seal at the time of the weekly
inspection, the Permittee shall:
i. Monitor the pump as specified in this permit and if the instrument reading indicates a reading of 2,000
parts per million (ppm) or greater it shall be repaired using the procedures in Sections 2.2 B.2.i
through 2.2 13.21, above; or
ii. Eliminate the visual indications of liquids dripping.
Any pump that is located within the boundary of an unmanned plant site is exempt from the weekly visual
inspection provided that each pump is visually inspected as often as practical and at least monthly.
t. If, when calculated on a 6-month rolling average for the percent leaking pumps, at least the greater of
either 10 percent of the pumps in a process unit or three pumps in a process unit leak, the Permittee shall
implement a quality improvement program for pumps Sections 2.2.B.2.bb through 2.2 B.2.gg,below.The
Permittee shall not alter the process grouping used in calculating this percentage.
i. The number of pumps at a process unit shall be the sum of all the pumps in VOC service, except that
pumps found leaking in a continuous process unit within one month after start-up of the pump shall
not count in the percent leaking pumps calculation for that one monitoring period only.
ii. Percent leaking pumps shall be determined by the following equation:

u. The Permittee shall monitor all connectors in gas and vapor and light liquid using instrumentation as
specified in this permit. If an instrument reading greater than or equal to 500 parts per million is measured,
a leak is detected. Any connector that is designated as unsafe-to-monitor is exempt from this requirement
and shall be monitored and inspected according to the written plan specified in Section 2.2 B.2.b, above.
v. The Permittee shall perform monitoring as specified below.
i. If the percent leaking connectors in the process unit was greater than or equal to 0.5 percent, then
monitor within 12 months (one year).

provided all connectors have been monitored by the end of the four year monitoring period.
iii. If the percent leaking connectors in the process unit was less than 0.25 percent the Permittee shall
monitor at least 50 percent of the connectors within four years of the start of the monitoring period
and
(A)Monitor as soon as practical,but within the next six months,all connectors that have not yet been
monitored during the monitoring period if the percent leaking connectors is greater than or equal
to 0.35 percent of the monitored connectors [At the conclusion of monitoring, a new monitoring
period shall be started based on the percent leaking connectors of the total monitored connectors.],
or
(B) Monitor all connectors that have not yet been monitored within eight years of the start of the
monitoring period if the percent leaking connectors is less than 0.35 percent of the monitored
connectors.
iv. If, during the monitoring, a connector is found to be leaking, it shall be re-monitored once within 90
days after repair to confirm that it is not leaking.
v. The Permittee shall keep a record of the start date and end date of each monitoring period under this
section for each process unit.

(or plant site)remains in the quality improvement program.
dd. The Permittee shall inspect all pumps or pump seals that exhibited frequent seal failures and were removed
from the process unit due to leaks. The inspection shall determine the probable cause of the pump seal
failure or of the pump leak and shall include recommendations, as appropriate, for design changes or
changes in specifications to reduce leak potential.
ee. The Permittee shall analyze the data collected to comply with the requirements of Section 2.2 B.2.cc,
above, to determine the services, operating or maintenance practices, and pump or pump seal designs or
technologies that have poorer than average emission performance and those that have better than average
emission performance.The analysis shall determine if specific trouble areas can be identified on the basis
of service, operating conditions or maintenance practices, equipment design, or other process-specific
factors.

Permit 01819T46
Page 43
i. The analysis shall also be used to determine if there are superior performing pump or pump seal
technologies that are applicable to the service(s),operating conditions,or pump or pump seal designs
associated with poorer than average emission performance.A superior performing pump or pump seal
technology is one with a leak frequency of less than 10 percent for specific applications in the process
unit.A candidate superior performing pump or pump seal technology is one demonstrated or reported
in the available literature or through a group study as having low emission performance and as being
capable of achieving less than 10 percent leaking pumps in the process unit.
ii. The analysis shall include consideration of the following information:
(A) The data obtained from the inspections of pumps and pump seals removed from the process unit
due to leaks;
(B) Information from the available literature and from the experience of other plant sites that will
identify pump designs or technologies and operating conditions associated with low emission
performance for specific services; and
(C) Information on limitations on the service conditions for the pump seal technology operating
conditions as well as information on maintenance procedures to ensure continued low emission
performance.
iii. The data analysis may be conducted through an inter- or intra-company program (or through some
combination of the two approaches) and may be for a single process unit, a plant site, a company, or
a group of process units.
iv. The first analysis of the data shall be completed no later than 18 months after the start of the quality
improvement program. The first analysis shall be performed using data collected for a minimum of
six months. An analysis of the data shall be done each year the process unit or affected facility is in
the quality improvement program.
ff. The Permittee shall prepare and implement a pump quality assurance program that details purchasing
specifications and maintenance procedures for all pumps and pump seals in the process unit. The quality
assurance program may establish any number of categories, or classes, of pumps as needed to distinguish
among operating conditions and services associated with poorer than average emission performance as
well as those associated with better than average emission performance. The quality assurance program
shall be developed considering the findings of the data analysis required under paragraph Section
2.2B.2.ee,above,and the operating conditions in the process unit.The quality assurance program shall be
updated each year as long as the process unit has the greater of either 10 percent or more leaking pumps
or has three leaking pumps.
i. The quality assurance program shall implement the following procedures.
(A)Establish minimum design standards for each category of pumps or pump seal technology. The
design standards shall specify known critical parameters such as tolerance, manufacturer,
materials of construction,previous usage, or other applicable identified critical parameters.
(B) Require that all equipment orders specify the design standard (or minimum tolerances) for the
pump or the pump seal.
(C) Provide for an audit procedure for quality control of purchased equipment to ensure conformance
with purchase specifications.
(D)Detail off-line pump maintenance and repair procedures. These procedures shall include
provisions to ensure that rebuilt or refurbished pumps and pump seals will meet the design
specifications for the pump category and will operate so that emissions are minimized.
ii. The quality assurance program shall be established no later than the start of the third year of the
quality improvement program.
gg. Three years after the start of the quality improvement program, the Permittee shall replace the pumps or
pump seals that are not superior emission performance technology with pumps or pump seals that have
been identified as superior emission performance technology and that comply with the quality assurance
standards for the pump category. Superior emission performance technology is that category or design of
pumps or pump seals with emission performance that when combined with appropriate process,operating,
and maintenance practices, will result in less than 10 percent leaking pumps for specific applications in
the process unit. Superior emission performance technology includes material or design changes to the

Permit 01819T46
Page 44
existing pump, pump seal, seal support system,installation of multiple mechanical seals or equivalent, or
pump replacement.
i. Pumps or pump seals shall be replaced at the rate of 20 percent per year based on the total number of
pumps in light liquid service. The calculated value shall be rounded to the nearest nonzero integer
value. The minimum number of pumps or pump seals shall be one. Pump replacement shall continue
until all pumps subject to the requirements of Sections 2.2 B.2.r through 2.2 B.2.t, above, are pumps
determined to be superior performance technology.
ii. The Permittee may delay replacement of pump seals or pumps with superior technology until the next
planned process unit shutdown,provided the number of pump seals and pumps replaced is equivalent
