methods.In addition to the above,the following equipment shall be specifically identified:
i. Connectors that are:
(A) Buried,insulated in a manner that prevents access by a monitor probe,
(B) 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

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 shutdown.

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:
(A) The date of first attempt to repair the leak;

(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.

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(Section 2.2 B.2.bb through Section 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;
(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;

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.

Permit 01819T54
Page 45
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:
(%VL,x V)�
%V
LO n
V J
Where: %VLo= Overall performance of total valves in the applicable process unit or group of process units
%VL; = Percent leaking valves in subgroup i,most recent value
V; =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 Ix 100
r

Permit 01819T54
Page 46
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 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.

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 Section 2.2 B.2.i through Section 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 Section 2.2 B.2.bb through Section 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.

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).
ii. If the percent leaking connectors in the process unit was greater than or equal to 0.25 percent but less than 0.5
percent,then monitor within four years.The Permittee may comply with this requirement by monitoring at least

The Permittee shall continue to collect data on the pumps as long as the process unit or affected facility(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.
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

An analysis of the data shall be done each year the process unit or affected facility is in the quality improvement
program.
f£ 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 in 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 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 Section 2.2 B.2.r through Section 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

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;

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(Section 2.2 B.2.bb through Section 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;

Permit 01819T54
Page 45
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:
(%VL,x V)�
%V
LO n
V J
Where: %VLo= Overall performance of total valves in the applicable process unit or group of process units
%VL; = Percent leaking valves in subgroup i,most recent value
V; =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 Ix 100
r

Permit 01819T54
Page 46
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 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.

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 Section 2.2 B.2.i through Section 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 Section 2.2 B.2.bb through Section 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.

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.
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

f£ 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 in 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.

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 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 Section 2.2 B.2.r through Section 2.2 B.2.t above,are pumps determined to be superior
performance technology.

FF. Title IV Allowances[15A NCAC 02Q.0508(i)(1)]
This permit does not limit the number of Title IV allowances held by the Permittee,but the Permittee may not use
allowances as a defense to noncompliance with any other applicable requirement. The Permittee's emissions may not
exceed any allowances that the facility lawfully holds under Title IV of the Federal Clean Air Act.
GG.Air Pollution Emergency Episode[15A NCAC 02D.0300]
Should the Director of the DAQ declare an Air Pollution Emergency Episode,the Permittee will be required to operate in
accordance with the Permittee's previously approved Emission Reduction Plan or,in the absence of an approved plan,with
the appropriate requirements specified in 15A NCAC 02D.0300.
HH.Registration of Air Pollution Sources[15A NCAC 02D.0202]
The Director of the DAQ may require the Permittee to register a source of air pollution. If the Permittee is required to
register a source of air pollution,this registration and required information will be in accordance with 15A NCAC 02D
.0202(b).
II. Ambient Air Quality Standards[15A NCAC 02D.0501(c)]
In addition to any control or manner of operation necessary to meet emission standards specified in this permit,any source
of air pollution shall be operated with such control or in such manner that the source shall not cause the ambient air quality
standards in 15A NCAC 02D.0400 to be exceeded at any point beyond the premises on which the source is located. When
controls more stringent than named in the applicable emission standards in this permit are required to prevent violation of
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).
