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

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 VQC 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 can not 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 deign 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

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.

Peirmit 61819T38
Page 53
(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:

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 semi-annual periodic report.
vi. The Permittee shall submit in the semi-annual 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
V.
Where: %VL = Percent leaking valves.

V1, = 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) 'ap 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 pert-ormcd to satisfy the

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:
(1) 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.
(2)Prescribe alternate test procedures on an individual-basis when he finds that the alternative
method is necessary to secure more reliable test data.
(3) Prescribe or approve methods on an individual basis for sources or pollutants for which no test
method is specified in this Section if the methods can be demonstrated to determine compliance
of permitted emission sources or pollutants.
b.The Director may authorize the Division of Air Quality.to conduct independent tests of any source
subject to a rule in this Subchapter 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 Section 2D .2600 has precedence over all
other tests.
