considered process unit shutdowns:
a. an unscheduled work practice or
operational procedure that stops production from a process unit or part of a
process unit for less than 24 hours;
b. an unscheduled work practice or
operational procedure that would stop production from a process unit or part of
a process unit for a shorter period of time than would be required to clear the
process unit or part of the process unit of materials and start-up the unit,
and would result in greater emissions than delay of repair of leaking
components until the next scheduled process unit
shutdown;
c. the use of
spare equipment and technically feasible bypassing or isolating of equipment
without stopping production; and

3. Leak Repair
a. The owner or operator shall make every
reasonable effort to repair a leaking component, as described in Paragraph C.1
or Subparagraph D.3.b of this Section, within 15 calendar days of detection. A
repair is considered successful if it meets any of the following conditions:
i. a component is monitored (or remonitored)
to verify that the instrument reading is below the applicable leak definition
in Paragraph C.1 of this Section;
ii. a component that has been identified as
leaking using the AWP, either meets Clause C.3.a.i of this Section, or the
emissions are no longer visible using the AWP; or
iii. a component in liquid service that has
been identified as leaking by visual, audible, or olfactory means, including,
use of the soap bubble test for natural gas processing plants, either meets
Clause C.3.a.i of this Section, or when visual, audible, or olfactory
indications of the leak have been eliminated.
b. Equipment that cannot be repaired shall be
placed on a delay-of-repair list, unless it can be isolated or bypassed to
eliminate the leak. Repair of equipment on the delay-of-repair list shall occur
by the end of the next scheduled process unit shutdown. The
administrative authority as defined in LAC 33:III.111.A
reserves the right to take enforcement action pursuant to
R.S.
30:2025, should it be determined that the
total percentage of components on the delay-of-repair list is excessive or is
causing damage to public health or the environment.
c. Equipment placed on the delay-of-repair
list in accordance with Subparagraph C.3.b of this Section may be removed from
the list if it meets any of the following conditions:

the leak limitation specified in Paragraph C.1 of this Section or there are no
visible emissions using an optical gas imaging instrument pursuant to the AWP;
or
ii. the owner or operator has
undertaken additional or extraordinary efforts to repair the leaking equipment,
and subsequent monitoring or imaging demonstrates that either the instrument
readings are below the leak limitation in Paragraph C.1 of this Section, or
there are no visible emissions using an optical gas imaging instrument pursuant
to the AWP. Extraordinary efforts are non-routine repair methods (e.g., sealant
injection, clamp installation) or utilization of a closed-vent system to
capture and control the leak by at least 90 percent.
(a). The decision to monitor equipment on the
delay-of-repair list or undertake extraordinary efforts to repair equipment
shall be made solely at the owner or operator's discretion.
D. Monitoring and Inspection Requirements.
Monitoring of components by method 21 and inspections shall be conducted
according to this Subsection. After initially complying with this Subsection,
the owner or operator may elect to comply with the appropriate alternate
monitoring schedule(s) in Subsection E of this Section. In lieu of method 21

of a description of the program to the administrative authority* and approval
thereof. A facility which has consolidated into an overall more stringent
program in accordance with the Louisiana Consolidated Fugitive Emissions
Program (i.e., with a source notice and agreement or a title V permit) is
exempted from having to submit a description of the program to the
administrative authority*. (The Louisiana fugitive emission program
consolidation guidelines are contained in LAC 33:III.2199.Appendix
B.)
6. Force Majeure
a. If a force majeure is about to occur,
occurs, or has occurred for which the affected owner or operator intends to
assert a claim of force majeure, the owner or operator shall notify the
administrative authority, in writing, as soon as practical following the date
the owner or operator first knew, or through due diligence should have known
that the event may cause or has caused a delay in monitoring beyond the
regulatory deadline. The notification shall occur before the monitoring
deadline unless the initial force majeure event delays the notice, and in such
cases, the notification shall occur as soon as practicable.
b. The owner or operator shall provide to the
administrative authority a written description of the force majeure event and a
rationale for attributing the delay in monitoring beyond the regulatory
deadline to the force majeure; describe the measures taken or to be taken to
minimize the delay; and identify a date by which the owner or operator proposes
to conduct the monitoring. The monitoring shall be conducted as soon as
practicable after the force majeure occurs.
c. The decision to grant an extension to the
monitoring deadline is solely within the discretion of the administrative
authority. The administrative authority shall notify the owner or operator in
writing of approval or disapproval of the request for an extension as soon as
practical.
d. Until an extension of
the monitoring deadline has been approved by the administrative authority under
Subparagraph D.6.c of this Section, the owner or operator of the affected
facility remains subject to the requirements of this Section.

one of the following alternate work practices. The batch product-process
equipment shall be tested with a gas using the procedure specified in
Subparagraph E.7.a of this Section or with a liquid using the procedure
specified in Subparagraph E.7.b of this Section.
a. The following procedure shall be used to
pressure test batch product-process equipment using a gas (e.g., air or
nitrogen) to demonstrate compliance.
i. The
batch product-process equipment train, or section of the train, shall be
pressurized with a gas to the operating pressure of the equipment. The
equipment shall be tested at a pressure lower than the lowest pressure setting
of any relief device.
ii. Once the
test pressure is obtained, the gas source shall be shut off.
iii. The test shall continue for not less
than 15 minutes, unless it can be determined in a shorter period of time that
the allowable rate of pressure drop was exceeded. The pressure in the batch
product-process equipment shall be measured after the gas source is shut off
and at the end of the test period. The rate of change in pressure in the batch
product-process equipment shall be calculated using Equation 3.
Equation 3
P
=
(Pf -
P)
t (tf
- ti)
where:
P/t = change in pressure, psi/hr
Pf = final pressure, psi
Pi = initial pressure, psi
tf - ti =
elapsed time, hours
iv. The
pressure shall be measured using a pressure measurement device (e.g., gauge,
manometer, or equivalent) that has a precision of +-2.5 millimeters (+-0.05
psi) of mercury over the range of measured test pressures and is capable of
measuring pressures up to the lowest pressure setting of any relief
device.
v. A leak is detected if
the rate of change in pressure (Equation 3) is greater than 6.9 kPa (1 psi) per
hour or if there is visible, audible, or olfactory evidence of a
leak.
b. The following
procedure shall be used to pressure test batch product-process equipment using
a liquid to demonstrate compliance.
i. The
batch product-process equipment train, or section of the train, shall be filled
with the test liquid (e.g., water, alcohol). Once the equipment is filled, the
liquid source shall be shut off.
ii. The test shall be conducted for a period
not less than 60 minutes, unless it can be determined in a shorter period of
time that the test is a failure.
iii. Each seal in the equipment being tested
shall be inspected for indications of liquid dripping or other indications of
fluid loss. If there are any indications of liquids dripping or of fluid loss,
a leak is detected.
c.
If a leak is detected, it shall be repaired and the batch product-process
equipment shall be retested before VOCs are fed to the equipment.
d. If the batch product-process equipment
fails the retest or the second of two consecutive pressure tests, it shall be
repaired as soon as practicable, but no later than 30 calendar days after the
equipment is placed in VOC service.
F. Recordkeeping
1. When a component remains leaking after
every reasonable attempt at repair within the 15-calendar day period provided
by Subparagraph C.3.a of this Section has been exhausted, a weatherproof and
readily visible tag bearing an identification number and the date the leak was
located shall be affixed to the leaking component. After the leak has been
repaired the tag may be removed.
2.
A survey log shall be maintained by the owner or operator and shall include the
following:
a. the name of the process unit
where the leaking component is located;
b. the type of the leaking
component;
c. the stream
identification at the leak;
d. the
identification number from the tag required by Paragraph F.1 of this
Section;
e. the date the leak was
located;
f. the date maintenance
was performed;
g. the date(s) the
component was rechecked after maintenance, and the results (i.e., instrument
reading; visual, audible, or olfactory results; soap bubble test results; AWP
video);
h. a record of the monitor
calibration or AWP daily instrument check;
i. a delay-of-repair list;
j. a bypassed or isolated component list;
and
k. a record of all monitoring,
imaging, and inspection results.
3. The owner or operator shall retain the
survey log for two years after the latest date specified in Paragraph F.2 of
this Section and make the log available to the administrative authority upon
request.
4. The optional use of the
AWP shall require storing video and other records of the daily instrument check
and inspections as required in
40 CFR
60.18.
G. Reporting Requirements. The owner or
operator of the affected facility shall submit a report semiannually to the
Office of Environmental Services containing the information listed in
Paragraphs G.1-5 of this Section for each calendar quarter during the reporting
period, except for affected facilities that elect to meet the requirements of
the alternate standard for batch processes in Paragraph E.5 of this Section,
for which the report shall include the information listed in Paragraphs G.6-9
of this Section. The reports are due by the last day of the month (January and
July) following the monitoring period or by an alternate date approved by the
administrative authority. The reports shall include the following information
for each quarter of the reporting period:
1.
the number of each component type for which monitoring is required by
Subsection D or E of this Section versus the number monitored;
2. the percent of leaking components
(Equation 1) for each component type and the number of leaks detected by
visual, audible, or olfactory means for each component type;
3. the total percent of leaking and
delay-of-repair components (Equation 2) for each component type;
4. a listing of all leaks that were
identified, but not repaired, within the 15-day limit, including the following
information:
a. the name of the process unit
where the leaking component is located and the date of last unit
shutdown;
b. the type of leaking
component;
c. the stream
identification at the leak;
d. the
identification number from the tag required by Paragraph F.1 of this Section,
if the component is on the delay-of-repair list;
e. the date the leak was located;
f. the monitoring or inspection
results;
g. the date maintenance
was performed;
h. the date the leak
is expected to be repaired if the component is on the delay-of-repair list;
and
i. the reason repairs failed or
were postponed;
5. a
signed statement attesting to the fact that all requirements of this Section
have been met;
6. the batch process
equipment train identification;
7.
the number of pressure tests conducted;
8. the number of pressure tests that the
equipment train failed; and
9. a
signed statement attesting to the fact that all requirements of this Section
have been met.
